Automobile Air Suspension Equalizer Beam Welding Positioning Device

Technical Field

The utility model relates to the technical field of air suspension equalizer beams, and particularly relates to an automobile air suspension equalizer beam welding positioning device.

Background Technology

The axle and air suspension system are connected through a floating connection, so that the rear axle pitch angle remains basically unchanged during vehicle operation. This facilitates spatial arrangement and allows the use of large-capacity air springs to improve vehicle ride comfort and overload resistance.

The equalizer beam and torque rod system serve as guiding and lateral force transmission components as well as stabilizing control mechanisms. They are mainly used to ensure driving stability and good anti-roll characteristics of the vehicle suspension under various road conditions.

Traditional equalizer beams mainly consist of a sleeve pipe, a middle clamping plate, and a rear spindle. The sleeve pipe and rear spindle are respectively fixed to two ends of the arc-shaped middle clamping plate, while another sleeve pipe passes through the middle portion of the middle clamping plate and is fixed thereto.

During manufacturing of the equalizer beam, workers first position the sleeve pipe, middle clamping plate, and rear spindle, and then weld them together. However, during the welding process, the positions of the components are prone to shifting, which affects welding accuracy and may even lead to product scrapping in severe cases.

Summary of the Utility Model

To address the above problems, the utility model provides an automobile air suspension equalizer beam welding positioning device capable of conveniently positioning the assembled components of the equalizer beam, preventing positional displacement during welding, ensuring welding accuracy, and improving work efficiency.

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

An automobile air suspension equalizer beam welding positioning device, comprising:

an operation frame,

a lifting mechanism,

a pressing member,

lower supporting members, and

a side supporting member.

Wherein:

The operation frame is a box-shaped structure with open front and rear ends.

The lifting mechanism is fixed on the top surface of the operation frame. The pressing member is positioned inside the operation frame and fixed to the lifting rod of the lifting mechanism.

The lower supporting members are fixed on the bottom surface inside the operation frame and located below the pressing member. The lower supporting members are mainly used for placing and supporting the sleeve pipe and middle clamping plate of the equalizer beam.

The side supporting member is connected to one side wall inside the operation frame and is mainly used for temporarily mounting and fixing the rear spindle of the equalizer beam.

Further, the lower end of the pressing member used for pressing and fixing the upper opening of the sleeve pipe is formed as a conical structure, so that it can more easily enter the upper opening of the sleeve pipe while also correcting the position of the sleeve pipe.

Further, the lower supporting members include a first type lower supporting member and a second type lower supporting member. The first type lower supporting member has a lower height than the second type lower supporting member.

The first type lower supporting member is arranged at the position for placing the sleeve pipe of the equalizer beam, while the second type lower supporting member is arranged at the position for placing the middle clamping plate, thereby fixing the middle clamping plate at a predetermined height on the side wall of the sleeve pipe.

Further, one end of the side supporting member is fixed to one side wall inside the operation frame, while the other end is provided with a socket for insertion of one end of the rear spindle of the equalizer beam. At this time, the other end of the rear spindle is butted against the other end of the middle clamping plate.

Further, a first positioning member is provided on the side wall of the socket end of the side supporting member. One end of the first positioning member passes through the side wall of the side supporting member and extends into the socket. The first positioning member is threadedly connected to the side wall of the side supporting member to temporarily fix the rear spindle.

Further, the lifting mechanism may be any one of an air cylinder, hydraulic cylinder, or the like, and is mainly used to drive the pressing member to position the assembled components of the equalizer beam and prevent displacement during welding.

Further, the lower supporting member is composed of an outer cylinder body and an inner supporting column. The outer cylinder body is fixed to the bottom surface inside the operation frame. The inner supporting column is positioned inside the outer cylinder body, and the bottom surface of the inner supporting column is threadedly connected to the bottom surface of the operation frame through a screw rod.

One end of the screw rod extends through the bottom surface of the operation frame to the lower side thereof, so that the height of the inner supporting column can be adjusted after welding, thereby facilitating removal of the equalizer beam from the operation frame.

Further, the device also includes a bracket, and the operation frame is suspended and fixed on the bracket so as to facilitate adjustment of the screw rod.

Further, both side walls of the operation frame are fixed to the bracket through rotating shafts, and the side walls of the rotating shafts are detachably connected to the bracket through second positioning members, so that after releasing the second positioning members, the position of the operation frame can be swing-adjusted.

Beneficial Effects

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

The automobile air suspension equalizer beam welding positioning device can utilize the lower supporting members and side supporting member to respectively mount the sleeve pipe, middle clamping plate, and rear spindle of the equalizer beam, allowing all components to be arranged according to predetermined positions.

The lifting mechanism and pressing member are then used to fix the positioned components, ensuring that the components do not shift during welding. As a result, the components can be connected more accurately to form the equalizer beam, thereby improving product qualification rate and work efficiency.

Detailed Description

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

Referring to Figure 1, an automobile air suspension equalizer beam welding positioning device includes an operation frame 1, lifting mechanism 2, pressing member 3, lower supporting member 4, and side supporting member 5.

The operation frame 1 is a box-shaped structure open at both the front and rear ends. The lifting mechanism 2 is fixed on the top surface of the operation frame 1, and the lifting rod extends into the frame body. The pressing member 3 is fixed to the lower end surface of the lifting rod.

The lifting mechanism 2 may be an air cylinder or hydraulic cylinder. The pressing member 3 is cylindrical and mainly used to position the assembled components of the equalizer beam under the driving action of the lifting mechanism, thereby preventing positional deviation during welding.

The lower supporting member 4 is fixed on the bottom surface inside the operation frame 1 and positioned below the pressing member 3. It is mainly used to support the sleeve pipe 6 and middle clamping plate 7.

The side supporting member 5 is fixed on one side wall inside the operation frame 1 and includes a socket for inserting one end of the rear spindle 8.

After all components are installed, the lifting mechanism 2 is activated to drive the pressing member 3 downward to press and fix the sleeve pipe 6 and middle clamping plate 7. Spot welding is then performed between the sleeve pipe 6 and middle clamping plate 7 and between the middle clamping plate 7 and rear spindle 8.

After spot welding, the equalizer beam is removed for further welding operations.

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.
