Description

Technical Field

[0001] This utility model relates to a vertical pressure sleeve tooling for a commercial vehicle stabilizer bar, belonging to the technical field of stabilizer bar lug bushing assembly. Background Technology

[0002] Bushings need to be installed at the lugs of the stabilizer bar. These bushings serve to position the stabilizer bar, limit its excessive displacement, buffer vibrations, and isolate noise. Currently, the assembly method for stabilizer bar lug bushings in commercial vehicles is mostly a horizontal hydraulic press, requiring two people to work together to press the bushings in place. The center distance after pressing still needs to be checked, and any defects such as improper pressing require rework, resulting in low production efficiency. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a vertical pressure sleeve tooling for commercial vehicle stabilizer bars, which can realize the precise assembly of stabilizer bar lug bushings, ensure the stability of assembly quality, and improve production efficiency.

[0004] The commercial vehicle stabilizer bar vertical pressing tooling of this utility model includes a lower pressing die and an upper pressing die. The lower pressing die can accurately position the end of the stabilizer bar. The lower pressing die is bolted to the top of the lower die base, and the lower die base is bolted to the lower worktable of the single-column hydraulic press. The upper pressing die is bolted to the upper die base, and the upper die base is fixedly connected to the upper template. The upper template is bolted to the upper worktable of the single-column hydraulic press. The upper pressing die and the lower pressing die are coaxially arranged. A crossbeam support rod is movably connected to the lower part of the lower die base. The crossbeam support rod is used to support the crossbeam part of the stabilizer bar to ensure the verticality of the stabilizer bar lug, thereby ensuring the smooth pressing of the bushing.

[0005] The technical solution of this utility model is to provide a vertical press sleeve tooling for a commercial vehicle stabilizer bar. The lower die of the press sleeve is used to accurately position the end of the stabilizer bar, and the crossbeam support rod supports the crossbeam part of the stabilizer bar to ensure that the ear hole of the stabilizer bar is vertical. The press sleeve is completed by the cooperation of the lower die and the upper die of the press sleeve.

[0006] Preferably, the lower die of the compression sleeve has a cavity, the shape of which is consistent with the shape of the stabilizer rod end, so as to accurately position the stabilizer rod end through the cavity.

[0007] Furthermore, the bottom of the cavity of the lower die of the press sleeve is provided with a through hole that is slightly larger than the outer diameter of the bushing, which can ensure that the bushing is installed in place.

[0008] Preferably, the working surface of the upper die of the press sleeve is machined with a blind hole with a draft angle. The blind hole can be used to automatically guide the bushing placed above the ear hole of the stabilizing rod so that it is perpendicular to the ear hole. The depth of the blind hole is consistent with the length of the bushing protruding outside the ear hole after it is assembled. Therefore, as long as the upper die of the press sleeve is pressed to the bottom, the installation accuracy and consistency of the bushing can be guaranteed.

[0009] Preferably, a limiting tube is provided through the lower part of the lower mold base, and the crossbeam support rod is movably disposed in the limiting tube. A top block is fixed on the limiting tube, and a top bolt is installed on the top block. The position of the crossbeam support rod can be locked by the top bolt.

[0010] Preferably, the end of the crossbeam support rod is provided with a support block, which is adapted to the crossbeam part of the stabilizer rod, and the support block supports and limits the crossbeam of the stabilizer rod.

[0011] The advantages of this utility model compared with the prior art are: 1. This utility model can achieve precise assembly of stabilizer bar lug bushings for commercial vehicles, reducing the defect rate of products and ensuring the stability of assembly quality; 2. This utility model can be operated by a single person without the need for two people to cooperate, thus improving production efficiency; 3. This utility model has strong versatility. When changing the model of different products, it is only necessary to replace the corresponding upper mold and lower mold of the pressure sleeve and adjust the crossbeam support rod to the appropriate position and fix it, which greatly saves the changeover time.

[0016] In this embodiment, the lower die 6 of the press sleeve is provided with a cavity 61, the shape of which is consistent with the shape of the end of the stabilizer rod 5, and the end of the stabilizer rod is precisely positioned through the cavity 61. The bottom of the cavity 61 of the lower die sleeve is provided with a through hole 62 that is slightly larger than the outer diameter of the bushing 2, which can ensure that the bushing 2 is installed in place.

[0017] The upper die 9 of the press sleeve has a blind hole 91 with a draft angle machined on its working surface. The blind hole 91 can be used to automatically guide the bushing placed above the ear hole of the stabilizer bar, making it perpendicular to the ear hole. The depth of the blind hole 91 is consistent with the length of the bushing 2 protruding outside the ear hole after assembly. Therefore, as long as the upper die 9 of the press sleeve is pressed to the bottom, the installation accuracy and consistency of the bushing 2 can be guaranteed. The lower die base 3 has a limiting tube 31 running through its lower part. The crossbeam support rod 4 is movably set in the limiting tube 31. A top block 33 is fixed on the limiting tube 31. A top bolt 32 is installed on the top block 33. The position of the crossbeam support rod 4 can be locked by the top bolt 32. The end of the crossbeam support rod 4 is provided with a support block 41. The support block 41 is adapted to the crossbeam part of the stabilizer bar 5. The support block 41 supports and limits the crossbeam of the stabilizer bar.

[0018] The working process of this utility model is as follows: 1. Place the end of the stabilizer bar 5 into the cavity 61 of the lower die 6 of the pressure sleeve; 2. Adjust the position of the crossbeam support rod 4 so that the support block 41 fits against the crossbeam part of the stabilizer rod 5, ensure the verticality of the lug of the stabilizer rod 5, tighten the top bolt 32, and lock the crossbeam support rod 4. 3. Place the bushing 2 at the lug of the stabilizer 5, and let the single-column hydraulic press 1 drive the upper die 9 of the press sleeve to descend. During the descent of the upper die 9, the blind hole 91 automatically guides the bushing 2 until the bushing 2 is pressed into place.
