[0025] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 to Figure 7 As shown, this embodiment proposes a vehicle shock absorber rubber bushing press-fitting device, and its structure includes a fixing frame 1. The workbench 11 in this embodiment is fixedly arranged on the fixing frame 1. The clamping structure 2 is arranged on the workbench 11, and is used to clamp and position the shock absorber. The press-fitting part 4 is arranged at the upper end of the clamping structure 2. The locking mechanism 5 is arranged on the press-fitting part 4, and is used to open and fix the rubber bushing on the press-fitting part 4 or to separate the rubber from the press-fitting part 4. The driving structure is arranged on the top of the fixing frame 1, and is used to make the press-fitting part 4 approach the clamping structure 2 or move away from the clamping structure 2.

[0027] The driving structure in this embodiment includes a telescopic member 3, the fixed end of the telescopic member 3 is fixedly connected to the top of the fixed frame 1, and the telescopic end of the telescopic member 3 is fixedly connected to the top of the first sliding rail 51. The telescopic member 3 in this embodiment is preferably a hydraulic cylinder or a pneumatic cylinder. Among them, the hydraulic cylinder or the cylinder is the prior art, and this embodiment will not be repeated. The compression of the shock absorbing member is achieved by the expansion and contraction of the telescopic member 3, which ensures that during the compression process, when the rubber bushing is placed in the mounting hole, there will be a certain buffering force.

[0028] The locking mechanism 5 in this embodiment includes a first locking member 41 and a second locking member 42, and a limit plate 43 is fixedly arranged on the outer surface of the first locking member 41 and the second locking member 42. The control structure is arranged on the top of the first locking member 41 and the second locking member 42, and is used to simultaneously control the first locking member 41 and the second locking member 42 to move closer to or away from each other. When the rubber bushing is sleeved on the first locking member 41 and the second locking member 42, the first locking member 41 and the second locking member 42 are driven to move in the direction away from each other, so as to ensure that the rubber bushing is stretched and fixed on the first locking member 41 and the second locking member 42; when the first locking member 41 and the second locking member 42 are close to each other, the rubber sleeve on the first locking member 41 and the second locking member 42 is separated from the first locking member 41 and the second locking member 42, so that the rubber sleeve can be built into the mounting hole of the shock absorber and separated from the first locking member 41 and the second locking member 42 to be taken out. Such a design ensures that the rubber sleeve can directly and evenly penetrate into the mounting hole of the shock absorber, thereby improving the qualified rate of the product.

[0029] In this embodiment, the first locking member 41 is provided with a connecting portion 411 and a positioning portion 412. The connecting portion 411 is a semi-cylindrical structure, and the positioning portion 412 is a semi-conical structure. The diameter of the positioning portion 412 close to the connecting portion 411 is larger than the diameter of the end away from the connecting portion 411. The second locking member 42 has the same structure as the first locking member 41. The design of the positioning portion 412 makes it easier for the first locking member 41 and the second locking member 42 to enter the mounting hole of the reducer.

[0030] The control structure in this embodiment includes a first sliding rail 51, a first sliding groove 511 is arranged on the first sliding rail 51, a first sliding member 61 is fixedly arranged on the top of the first locking member 41, and a second sliding member 62 is fixedly arranged on the top of the second locking member 42. The first sliding member 61 and the second sliding member 62 are both slidingly connected to the first sliding groove 511, and the adjusting screw 53 is rotatably arranged in the first sliding groove 511. The first external thread 531 and the second external thread 532 are arranged on both sides of the adjusting screw 53. The first external thread 531 and the second external thread 532 rotate in opposite directions, so as to simultaneously control the first sliding member 61 and the second sliding member 62 to move toward or away from each other when the first adjusting bolt 52 rotates, thereby improving the adjustment efficiency. The first sliding member 61 is threadedly connected to the first external thread 531, the second sliding member 62 is threadedly connected to the second external thread 532, the first adjusting bolt 52 is fixedly arranged at the end of the adjusting screw rod 53, and the first adjusting bolt 52 is threadedly connected to the first sliding rail 51, so as to more accurately adjust the opening and locking of the rubber bushing by the first locking member 41 and the second locking member 42. Such a design can ensure that when the first locking member 41 and the second locking member 42 open and hold the rubber bushing, the center of the rubber bushing is always aligned with the center of the clamping structure 2, and the positioning of the rubber bushing deep into the shock absorber mounting hole is more accurate. Such a design ensures that after the adjustment is completed, the positions of the first sliding member 61 and the second sliding member 62 can be self-locked due to the threaded connection of the first adjusting bolt 52 and the sliding rail, so that the adjustment result can be maintained.

[0031] The clamping structure 2 in this embodiment includes a second sliding rail 21 fixedly arranged on the workbench 11, a second sliding groove 211 arranged in the second sliding rail 21, a first clamping member 71 and a second clamping member 72 slidingly arranged in the second sliding groove 211, a first clamping groove 711 arranged on the side of the first clamping member 71 close to the second clamping member 72, a second clamping groove 721 arranged on the side of the second clamping member 72 close to the second clamping member 72, and the first clamping groove 711 and the second clamping groove 721 are both semicircular structures. A placement notch 24 is provided on the center of the second sliding rail 21, the first clamping member 71 and the second clamping member 72 for placing a reducer. A first adjustment structure is arranged at one end of the second sliding rail 21 to control the displacement of the first clamping member 71. A second adjustment structure is arranged at the other end of the second sliding rail 21 to control the displacement of the second clamping member 72. Such a design of the first clamping member 71 and the second clamping member 72 can ensure that when there are reducers of different models and sizes, the position of the reducer can be repositioned by changing the positions of the first clamping member 71 and the second clamping member 72, thereby expanding the scope of application of this embodiment.

[0032] The first adjustment structure in this embodiment includes a second adjustment bolt 23, and a threaded hole 22 is provided at one end of the second sliding rail 21, which is threadedly connected to the second adjustment bolt 23. The limiting hole 712 is provided on the first clamp 71, and the rotating hole 7121 is provided on the side wall of the limiting hole 712, and the adjustment bolt is rotatably connected to the rotating hole 7121. The limiting bolt 231 is provided in the limiting hole 712, and is fixedly connected to the second adjustment bolt 23. The structures of the first adjustment structure and the second adjustment structure are the same. Such a design ensures that after the adjustment is completed, the positions of the first clamp 71 and the second clamp 72 can be self-locked, and the adjustment result can be maintained due to the threaded connection between the second adjustment bolt 23 and the threaded hole 22.

[0033] This embodiment can be provided with a high-precision servo motor system, a motion control system and a data acquisition host system. The programmable control terminal and the motion control system can be coordinated to accurately control the operation of the equipment based on the production parameters input from the external touch screen. In this embodiment, the press machine can detect the installation status of the sliding bearing and the stop ring in the guide by cooperating with the tooling and the photoelectric sensor, thereby reducing the generation of waste products.

[0034] Since various automobiles have different appearances, shock absorbers are also diverse. The press-fitting equipment in this embodiment can set different parameters through the touch screen, and can be compatible with all shock absorbers within the press-fitting range. During the production process, the production process is detected in real time through the force and displacement curve. After completion, the production process is judged to ensure the accuracy of the press-fitting, and important data in the production process is stored through the upper system to provide a digital basis for the later inspection of the shock absorber.

[0035] This embodiment adopts high-precision motion control equipment such as servo motors. Through different control methods such as pressure control, displacement control, and dual control of force and displacement, it is suitable for various pressing needs. The pressing accuracy can be accurate to within 0.01 mm. The force and displacement curve is used for real-time monitoring during the pressing process, and the local database stores important data of the processing process.

[0036] This embodiment changes the traditional hydraulic press-fitting method, adopts electronic equipment, saves energy and reduces emissions, greatly improves the press-fitting accuracy, and uses force and displacement press-fitting curve detection during the press-fitting process to make the press-fitting process more accurate. Through the coordination of tooling and photoelectric sensors to prevent errors, the scrap rate is reduced.

[0037] The working process of this embodiment is as follows: first, place the shock absorber to be press-fitted between the first clamping groove 711 and the second clamping groove 721, and then rotate the second adjusting bolt 23 on the first adjusting structure and the second adjusting bolt 23 on the second adjusting structure respectively, so that the first clamping member 71 and the second clamping member 72 clamp the shock absorber. Then, the rubber bushing is sleeved on the first locking member 41 and the second locking member 42, and at this time, the first adjusting bolt 52 is rotated so that the first locking member 41 and the second locking member 42 open and fix the rubber bushing, and then the telescopic member 3 is started to drive the rubber bushing to move down to the mounting hole of the shock absorber, and then the first adjusting bolt 52 is rotated to separate the rubber bushing from the first locking member 41 and the second locking member 42, and the first locking member 41 and the second locking member 42 are taken out through the telescopic member 3.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
