A Repair Fixing Tooling for Automotive Axles

Technical Field

The present invention relates to the technical field of automobile manufacturing, and in particular to a repair fixing tooling for an automotive axle.

Background Technology

An automobile axle (also known as an axle shaft) is connected to the vehicle frame (or unibody structure) through the suspension, with wheels mounted at both ends. The function of the axle is to bear the vehicle load and maintain the normal driving condition of the vehicle. According to different driving modes, axles are generally classified into steering axles, drive axles, steering drive axles, and support axles. Among them, steering axles and support axles belong to driven axles.

Most automobiles adopt a front-engine rear-drive (FR) configuration, where the front axle serves as the steering axle and the rear axle serves as the drive axle; while in front-engine front-drive (FF) vehicles, the front axle acts as the steering drive axle and the rear axle functions as the support axle.

Automobile axles sometimes require maintenance and repair. During repair operations, the axle must first be properly positioned to facilitate disassembly and assembly. If the axle is placed directly on the ground, operators must bend over to work, which is inconvenient and labor-intensive. In addition, placing the axle directly on the ground can easily cause shaking or collision of certain parts of the axle, resulting in scratches or damage.

Summary of the Invention

The purpose of the present invention is to provide a repair fixing tooling for automotive axles, which can effectively solve the technical problems mentioned in the background technology.

To achieve the above objective, the present invention provides the following technical solution:

A repair fixing tooling for automotive axles comprises a fixing frame base. Supporting legs for standing on the ground are arranged on the lower surface of the fixing frame base. One side of the upper surface of the fixing frame base is provided with a sliding groove penetrating through both ends of the fixing frame base. Two sliding seats capable of moving along the sliding groove are arranged inside the sliding groove.

Threaded connection holes are formed on the sliding seats. An axle support assembly is arranged above the sliding seats. The axle support assembly includes support rods connected into the threaded connection holes. The upper ends of the support rods are provided with axle positioning blocks. Each axle positioning block is composed of a fixed bottom plate and limiting blocks connected to both ends of the fixed bottom plate.

A pressing plate for pressing the sliding seat tightly into the sliding groove is arranged on the sliding seat. One end of the pressing plate is provided with a positioning hole, through which a screw rod passes. The lower end of the screw rod is connected to the fixing frame base, and a locking nut is arranged above the pressing plate on the screw rod.

Preferably, the tooling further includes a turnover assembly for rotating the axle. The turnover assembly includes a turnover plate, the lower end of which is connected to an inclined first pull rod. The lower end of the first pull rod is connected to a horizontally arranged second pull rod. One end of the second pull rod passes through a guide hole on a fixing plate and is threadedly connected with a limiting nut. The fixing plate is connected to the fixing frame base.

Preferably, the pressing plate has a rectangular structure.

Preferably, the side walls and bottom surface of the sliding groove are coated with a lubricating layer.

Preferably, the lubricating layer is made of graphite material.

Preferably, the lower surface of the pressing plate is provided with a protective pad made of soft material.

Preferably, a spacer block is arranged between the pressing plate and the fixing frame base.

Preferably, the fixing plate is welded to the fixing frame base.

Beneficial Effects

Compared with the prior art, the present invention has the following beneficial effects:

The two ends of the automobile axle are respectively placed on the fixed bottom plates of the axle positioning blocks. The limiting blocks at both ends of the fixed bottom plates are used to limit the axle position, so that the automobile axle can be stably positioned between the two axle positioning blocks, facilitating disassembly and assembly operations by operators.

When applied to automobile axles of different lengths and specifications, it is only necessary to move the sliding seats along the sliding groove and adjust their positions. Afterwards, the pressing plate is tightly pressed against the sliding seat by tightening the locking nut, thereby preventing arbitrary movement of the sliding seat and ensuring the stability of the axle placement.

During the disassembly and assembly process, when the automobile axle needs to be appropriately turned or rotated, the operator only needs to pull the second pull rod. The turnover plate will provide a rotational pulling force to the automobile axle, causing moderate rotation and facilitating position adjustment by the operator.

In addition, the lubricating layer coated on the side walls and bottom surface of the sliding groove facilitates smooth movement of the sliding seats along the sliding groove.

Detailed Description

Referring to Figures 1 and 2, the repair fixing tooling for automotive axles includes a fixing frame base 1. Supporting legs 2 used for supporting the tooling on the ground are arranged on the lower surface of the fixing frame base 1. A sliding groove 3 penetrating through both ends of the fixing frame base 1 is formed on one side of the upper surface of the fixing frame base 1. Two sliding seats 4 capable of moving along the sliding groove 3 are arranged inside the sliding groove 3.

Threaded connection holes 5 are formed on the sliding seats 4. An axle support assembly is arranged above the sliding seats 4. The axle support assembly includes support rods 6 connected into the threaded connection holes 5. The upper ends of the support rods 6 are provided with axle positioning blocks. Each axle positioning block is composed of a fixed bottom plate 7 and limiting blocks 8 connected to both ends of the fixed bottom plate 7.

The sliding seats 4 are provided with pressing plates 9 for pressing the sliding seats 4 tightly into the sliding groove 3. One end of each pressing plate 9 is provided with a positioning hole 10. A screw rod 11 passes through the positioning hole 10, with the lower end connected to the fixing frame base 1. A locking nut 12 is arranged above the pressing plate 9 on the screw rod 11.

The repair fixing frame further includes a turnover assembly for rotating the automobile axle. The turnover assembly includes a turnover plate 13. The lower end of the turnover plate 13 is connected to an inclined first pull rod 14, whose lower end is connected to a horizontally arranged second pull rod 15. One end of the second pull rod 15 passes through a guide hole on a fixing plate 16 and is threadedly connected with a limiting nut 17. The fixing plate 16 is connected to the fixing frame base 1.

The pressing plate 9 is of rectangular structure. The side walls and bottom surface of the sliding groove 3 are coated with a lubricating layer made of graphite material. The lower surface of the pressing plate 9 is provided with a protective pad made of soft material. A spacer block is arranged between the pressing plate 9 and the fixing frame base 1. The fixing plate 16 is welded to the fixing frame base 1.

The two ends of the automobile axle are respectively placed on the fixed bottom plates 7 of the axle positioning blocks. The limiting blocks 8 at both ends of the fixed bottom plates 7 are used for positioning limitation, so that the automobile axle can be stably placed between the two axle positioning blocks, thereby facilitating assembly and disassembly operations.

When applied to automobile axles with different lengths and specifications, the sliding seats 4 only need to be moved along the sliding groove 3 and adjusted to appropriate positions. Subsequently, the pressing plates 9 are tightly pressed against the sliding seats 4 through the locking nuts 12, thereby preventing random movement of the sliding seats 4 and ensuring the stability of the axle placement.

During axle maintenance and disassembly operations, when moderate turning or rotation of the automobile axle is required, the operator only needs to pull the second pull rod 15. The turnover plate 13 then provides rotational pulling force to the automobile axle, enabling moderate rotation and convenient position adjustment.

Furthermore, the lubricating layer coated on the side walls and bottom surface of the sliding groove 3 facilitates smooth movement of the sliding seats 4 along the sliding groove 3.
