Technical Field

[0001] This invention belongs to the field of air conditioner compressor bracket processing technology. Specifically, this invention relates to a pre-deformation tooling for the inner bushing of an automotive air conditioner compressor bracket. Background Technology

[0002] The automotive air conditioning compressor is the heart of the automotive air conditioning refrigeration system, playing the role of compressing and transporting refrigerant vapor. The automotive air conditioning compressor is installed in the engine compartment of the car by means of a corresponding compressor bracket. Due to the limited space in the engine compartment, the design and structure of the compressor bracket plays a significant role in securing the automotive air conditioning compressor and saving engine compartment space.

[0003] In the existing automotive air conditioning compressor bracket tooling, after verifying the stiffness and performance of the NBR rubber bushing, it was found that the current tooling does not have the ability to reverse the deformation caused by the 5N torque gun. The bushing cannot enter the pre-deformation state in advance, which leads to problems such as poor performance caused by bushing deformation. Summary of the Invention

The L-shaped push block abuts against the limiting post.

[0008] Preferably, the propulsion assembly includes a strip plate and a support platform. The strip plate is fixedly connected to the top of the tooling base, and the support platform is fixedly connected to the back of the tooling base. A second motor is fixedly connected to the rear side of the top of the support platform via a second base. A lead screw is fixedly connected to the output end of the second motor. The other end of the lead screw is rotatably connected to the back of the strip plate. A threaded block is threaded onto the surface of the lead screw. The bottom of the threaded block is slidably connected to the top of the support platform. Limiting mechanisms are fixedly connected to both sides of the top of the support platform.

[0009] Preferably, the limiting mechanism includes a fixing block, which is fixedly connected to the rear side of the top of the support platform. A limiting rod is fixedly connected to the front of the fixing block. One end of the limiting rod is fixedly connected to the back of the strip plate. A sliding sleeve is sleeved on the front side of the surface of the limiting rod. A slider is fixedly connected to the bottom of the sliding sleeve. The bottom of the slider is slidably connected to the top of the support platform.

[0010] Preferably, the clamping assembly includes a telescopic cylinder, which is fixed to the bottom of the tooling base via a third base.

[0013] The beneficial effects of adopting the above technical solutions are:

[0014] I. This invention applies a force in the opposite direction to the deformation of the rubber bushing in the compressor bracket in advance by setting a tooling anti-pre-deformation component. This effectively avoids the deformation of the rubber bushing caused by the torque gun during bolt installation of the compressor bracket, reduces the performance problems of the compressor bracket caused by bushing deformation, and improves the product processing quality.

[0015] Second, by setting up a propulsion component, this invention enables the pre-variant plate to more accurately align with the holes on the bushing during the docking process between the pre-variant component and the bushing in the compressor bracket, saving labor costs, automating the entire process, and effectively improving the product processing efficiency.

[0016] Third, the present invention can effectively fix the compressor bracket by adding a clamping component, avoiding the phenomenon that the compressor bracket will shift during the bolt tightening process, thus preventing damage to the workpiece. In addition, the convex block, first ear plate, trapezoidal block and third ear plate in the clamping component can not only fix the compressor bracket according to its own structural characteristics, but also the clamping component uses little space, which can better fix the compressor bracket.

[0042] Both sides of the top of the tooling base 1 are provided with arc-shaped bevels.

[0043] The specific working method is described below using specific embodiments: Example 1

[0044] The staff controls the second motor 23 to rotate forward, which drives the lead screw 24 to rotate, causing the threaded block 25 to move backward along the support platform 22, thereby driving the anti-pre-deformation component 3 to move backward;

[0045] Next, by controlling the external feeding device, the arc openings on both sides of the bottom of the compressor bracket are aligned with the arc-shaped positioning block 5 and placed. After the compressor bracket is placed, the telescopic cylinder 41 is extended, thereby driving the convex block 42 to move upward. The upward movement of the convex block 42 causes the first ear plate 43 and the third ear plate 46 to rotate along the connection point with the convex block 42, thereby pushing the trapezoidal block 44 to tilt and press to the side, thus completing the fixation of the compressor bracket. Example 2

[0046] After the compressor bracket is fixed, the operator controls the second motor 23 to reverse, thereby driving the lead screw 24 to rotate. This causes the threaded block 25 to move forward along the support platform 22, which in turn moves the anti-pre-deformation component 3 forward until the pre-deformation plate 324 of the inserting rotating plate mechanism 32 in the anti-pre-deformation component 3 enters the rubber bushing hole on the compressor bracket. Then, by controlling the first motor 36 to rotate forward, the operator drives the cam 37 to rotate. The farthest arc of the cam 37 pushes the elliptical limit plate 35 to move to the left, thereby driving the strip slider 264 to slide to the left along the slide rail. This causes the L-shaped push block 34 to move to the left, so that the limit post 325 moves in a circle around the turntable 323 as the center point, thereby driving the turntable to rotate. This causes the two pre-deformation plates 324 to rotate, thereby applying an anti-deformation reaction force to the rubber bushing on the compressor bracket. Finally, the operator controls the external torque wrench to tighten the bolts of the compressor bracket.

[0047] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other situations without modification, are all within the protection scope of the present invention.
