Rear Cross Beam Stabilizer Bar Welding Auxiliary Device for Automobile Suspension System

Technical Field

The utility model relates to the technical field of automobile parts, and particularly relates to a rear cross beam stabilizer bar welding auxiliary device for an automobile suspension system.

Background Technology

Automobile air suspension systems are mainly used for transporting precision objects and fragile goods, such as hazardous chemical transport vehicles and large precision equipment transport vehicles. Air suspension systems have the advantages of simple structure, convenient use, easy maintenance, and high riding comfort.

However, vehicles are prone to body roll during turning. The function of the rear transverse stabilizer bar is to prevent excessive lateral body roll when the vehicle turns and to maintain vehicle balance as much as possible. During turning, the vehicle body tilts, and the suspension movement on both sides becomes inconsistent. The outer suspension compresses the stabilizer bar, causing the stabilizer bar to twist. The elastic force of the bar prevents the wheel from lifting, thereby maintaining vehicle balance and providing lateral stability.

The traditional rear cross beam stabilizer bar mainly consists of a tee pipe joint and a pipe beam. Generally, the pipe beam is welded to one port of the tee pipe joint. During welding, it is necessary to ensure accurate alignment of the two components. At present, most methods rely on manual alignment, which results in low precision and slow efficiency, thereby reducing production efficiency.

Summary of the Utility Model

In view of the above problems, the utility model provides a rear cross beam stabilizer bar welding auxiliary device for an automobile suspension system, capable of assisting operators in aligning the various components of the rear cross beam more accurately and improving welding precision.

To achieve the above purpose, the utility model adopts the following technical solution:

A rear cross beam stabilizer bar welding auxiliary device for an automobile suspension system, comprising:

an operation box,

a first adjustment mechanism arranged on the left side of the operation box, and

a second adjustment mechanism arranged on the right side of the operation box.

Wherein:

The first adjustment mechanism includes an adjustment rod, a pressing block, a mounting shaft, a guide rod, and a support pad.

The upper end of the operation box is open. The adjustment rod is connected to the left side wall of the operation box and is capable of telescopic movement relative to the inner cavity of the operation box.

The pressing block located inside the operation box is fixed to the adjustment rod.

Both ends of the front wall of the operation box are provided with first through holes, while the rear wall of the operation box is provided with second through holes corresponding to the first through holes.

The mounting shaft is supported inside the operation box through the guide rod, and both ends of the guide rod pass through the first through holes and second through holes respectively.

The pressing block is aligned with the mounting shaft but is not connected thereto. The guide rod can advance within the through holes under the pushing action of the pressing block.

The structure and connection relationship of the second adjustment mechanism are identical to those of the first adjustment mechanism.

The support pad is fixed on the bottom surface inside the operation box and located between the two mounting shafts.

Further Technical Features

Further, the adjustment rod is a screw rod threadedly connected to the side wall of the operation box, and the adjustment rod is perpendicular to the side wall of the operation box.

Further, the outer end of the adjustment rod is connected with a first handle for conveniently rotating the adjustment rod.

Further, the surface of the pressing block facing the mounting shaft is formed as an arc-shaped groove so as to facilitate contact with the outer wall of the tee pipe joint sleeved on the mounting shaft.

Further, each guide rod is composed of two rod bodies detachably connected to both ends of the mounting shaft. Optionally, the rod bodies are threadedly connected to the mounting shaft to facilitate assembly and disassembly.

Further, the outer end of the guide rod is connected with a second handle for conveniently driving the guide rod into and out of the through holes.

Further, sleeves are fixed inside the first through holes and second through holes, and both ends of the guide rod extend outside the operation box after passing through the sleeves.

Further, the upper surface of the support pad is provided with a groove for constraining and supporting the pipe beam of the workpiece and preventing it from falling. Optionally, the groove may be an arc-shaped groove, a V-shaped groove, a U-shaped groove, or the like.

Beneficial Effects

Compared with the prior art, the utility model has the following beneficial effects:

The rear cross beam stabilizer bar welding auxiliary device can utilize the mounting shafts to mount the tee pipe joints of the workpiece to be welded, while the support pad supports the pipe beam between the two tee pipe joints and accurately aligns one port of each tee pipe joint with the port of the pipe beam.

The adjustment rod then drives the pressing block forward, thereby pushing the mounting shaft carrying the tee pipe joint to tightly press against and connect with the pipe beam, accurately completing the positioning between the tee pipe joint and the pipe beam.

Welding is then performed. After completion, the tee pipe joint is separated from the mounting shaft, and the welded workpiece can be removed from the inner cavity of the operation box.

It can therefore be seen that the auxiliary device can assist operators in aligning the components of the rear cross beam more conveniently and accurately, thereby improving welding precision.

Detailed Description

For convenience of description, the terms “upper,” “lower,” “left,” and “right” merely correspond to the directions shown in the drawings and do not limit the structure.

Referring to Figure 1, a rear cross beam stabilizer bar welding auxiliary device for an automobile suspension system includes an operation box 1, a first adjustment mechanism, and a second adjustment mechanism arranged on the left and right sides of the operation box respectively.

The first adjustment mechanism includes an adjustment rod 2, a pressing block 3, a mounting shaft 4, a guide rod 5, and a support pad 6.

The operation box 1 is an open-top rectangular box structure. The adjustment rod 2 is a screw rod threadedly connected to a threaded hole on the left side wall of the operation box 1. One end of the adjustment rod extends into the inner cavity of the operation box 1, and the adjustment rod is perpendicular to the side wall of the operation box. Therefore, rotating the adjustment rod allows telescopic movement relative to the inner cavity.

The pressing block 3 is located inside the operation box 1 and fixed to the end of the adjustment rod 2. The pressing block has a larger contact area than the end of the adjustment rod, thereby preventing slipping when pressing the outer wall of the tee pipe joint.

The mounting shaft 4 is supported inside the operation box 1 through the guide rod 5, and both ends of the guide rod extend outside the operation box through the first through holes 7 and second through holes 8.

The mounting shaft 4 is used for mounting the tee pipe joint 10 of the workpiece to be welded.

The pressing block 3 is aligned with the mounting shaft 4 but not connected thereto. The guide rod 5 can advance inside the through holes under the pushing action of the pressing block.

Several support pads 6 are fixed on the bottom surface inside the operation box 1 between the two mounting shafts 4. The support pads 6 are used to support the pipe beam 13 of the workpiece so that its pipe opening is aligned with the pipe opening of the tee pipe joint 10 at the same height for convenient docking.

The auxiliary device of the present embodiment can accurately position the tee pipe joint and pipe beam together through the pressing action of the adjustment rod and pressing block, thereby improving welding precision and production efficiency.

Finally, it should be noted that any modifications, equivalent substitutions, or improvements made within the spirit and principles of the utility model shall fall within the protection scope of the utility model.
