[0002] Shock absorber assembly refers to the process of integrating the various components of the shock absorber. The main function of the shock absorber is to absorb and attenuate the vibration and impact generated by the vehicle during driving, thereby improving the stability and comfort of the vehicle. The shock absorber is an important part of the automobile suspension system and directly affects the vehicle's handling performance and ride comfort. Modern shock absorber technology is constantly improving, from traditional hydraulic shock absorbers to electronically controlled shock absorbers and even pneumatic suspension systems.

[0003] In the traditional shock absorber assembly process, due to the lack of effective auxiliary equipment, workers often need to squat on the ground for a long time to assemble, resulting in high labor intensity and low work efficiency. However, in actual use, the inventors found that due to the low efficiency of manual assembly, the production cycle of the shock absorber is long and the production cost is relatively high. In addition, errors are prone to occur during the manual assembly process, resulting in unstable product quality, which further increases the production cost problem. Summary of the Invention

[0040] The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings.

[0041] Example 1 like Figure 1 As shown, a semi-automatic assembly system for a shock absorber comprises: A rear shock-absorbing sleeve press-fitting device 1 includes a first positioning fixture 12 mounted on a work platform a11 and a press-fitting fixture a13 located in front of the first positioning fixture 12. After the damper 100 is placed on the first positioning fixture 12, it is moved below the press-fitting fixture a13, which presses the bushing into the damper. A front decelerator spring disc press-fitting device 2 includes a second positioning fixture 22 mounted on a work platform b21 and a press-fitting fixture b23 located above the second positioning fixture 22. The damper 100 is placed on the second positioning fixture 22. The press-fitting fixture b23 installs the front decelerator spring disc 200 on the damper 100. A first cap press-fitting device 3 includes a carrier a32 mounted on a work platform c31, a centering assembly a33 disposed on one side of the carrier a32, and a press-fitting tool c34 located above the carrier a32. After the damper is placed on the carrier a32, the centering assembly a33 centeringly positions the damper, and the press-fitting tool c34 press-fits the first cap onto the damper 100. A vibration isolation rubber block installation device 4 includes a carrier b42 installed on a work platform d41, a centralizing assembly b43 located on one side of the carrier b42, and a press-fitting tool d44 located above the centralizing assembly b43. After the damper 100 is placed on the carrier b42, the centralizing assembly b43 centralizes the damper. A spring below the press-fitting tool d44 acts on the damper to manually pre-install the tower top nut. The yoke mounting device 5 includes a carrier c52 mounted on a working platform e51, a splitting assembly 53 longitudinally symmetrically arranged on both sides of the carrier c52, a positioning assembly a54 laterally symmetrically arranged on both sides of the carrier c52, and a tightening assembly a55 arranged on the other side of the positioning assembly a54.

[0042] Further, if Figure 2-4 As shown, the first positioning fixture 12 includes a support seat a121, a bottom bracket 122 that slides on the support seat a121 in the form of a pulley rail and matches the shape of the damper, a positioning track 123 that is arranged in parallel on one side of the bottom bracket 122 and has a serrated structure at the upper end, and an elastic ball 124 that is arranged below the bottom bracket 122 and intermittently matches and engages with the positioning track 123; The pressing tool a13 includes a press a131 and a positioning seat 132 installed under the press a131. The part of the damper to be pressed is matched and placed on the positioning seat 132 and a limiting column 133 is provided in the middle of the positioning seat 132. After the bushing is matched and placed on the limiting column 133, the press a131 presses the bushing onto the part of the damper to be pressed.

[0043] Among them, a CCD detection camera is set on the rear side of the press tool a13. The CCD detection camera is installed on the working platform a11. The CCD detection camera is used to detect whether the bushing and the damper are in place. When they are in place, the sensor transmits the signal and the press a131 starts working; Moreover, the first positioning tool 12 is arranged crosswise with the installation direction of the pressing tool a13. A bushing material rack 14 is also provided on the working platform a11. A damper temporary storage tool 15 is provided in front of the bushing material rack 14. The damper temporary storage tool 15 includes a mounting frame 151 installed on the working platform a11, a bracket a152 located on one side of the mounting frame 151 and vertically arranged, and a bayonet a153 provided on the bracket a152 and adapted to the shape of the damper. One end of the damper is inserted into the mounting frame 151, and the rod part of the damper is tilted and leans on the bayonet a153. The damper temporary storage tool 15 can quickly place qualified press-fitted products therein for temporary storage. During the pressing working time, the qualified products will be transferred to the next workstation, which is in line with the work rhythm.

[0044] Furthermore, an NG temporary storage component a16 is provided between the damper temporary storage tooling 15 and the first positioning tooling 12. The NG temporary storage component a16 includes a feed cylinder a161 and a storage box a162 provided below the feed cylinder a161. Its function is to transfer defective products in the storage box a162. At the same time, the vertically arranged feed cylinder a161 facilitates guided feeding of defective products on the one hand, and facilitates human operation on the other hand. When the operator removes the product from the first positioning tooling 12, he instinctively holds the damper vertically, which facilitates quick operation, reduces the frequency and intensity of manual operation of workers, reduces labor intensity, improves the working environment, and helps to attract and retain skilled workers.

[0045] In this embodiment, by equipping a precise first positioning tool 12 in combination with a pressing tool a13, it is possible to ensure that the workpiece remains stable during the processing, reduce human errors, and improve processing accuracy. Although the initial investment may be high, in the long run, the semi-automatic processing tool can reduce the manufacturing cost of each unit product because it improves production efficiency and reduces scrap rate.

[0046] It should be noted that by setting up the first positioning tool 12, the position of the damper can be easily adjusted, and the loading position and the pressing position can be smoothly switched to avoid mutual interference between the workstations. At the same time, the elastic ball 124 is used in conjunction with the positioning rail 123, so that the damper can be automatically limited when moved to any position. The loading station requirements for the operator are flexible, easy to use and precise processing. This structure has certain flexibility and can be adjusted and reconfigured according to different processing requirements. It is suitable for a variety of different types of workpieces and processing tasks.

[0047] Further, if Figure 5-7As shown, the second positioning tool 22 includes a bracket b221, a first sliding frame 222 that moves horizontally on the bracket b221 in the form of a pulley rail, and a support block 223 is connected to the bottom of the first sliding frame 222, and the support block 223 slides in a sliding groove 224 provided on the bracket b221; The pressing tool b23 includes a press b231 and a pressing head a232 arranged at the lower end of the press b231. The pressing head a232 is provided with a bayonet b233 that is adapted to the shape of the damper and has an arc-shaped structure. Its lower surface is adapted to the upper surface structure of the front spring disc 200. It includes a serrated protrusion block 234 and protrusion columns 235 located at both ends.

[0048] In this embodiment, by coordinating the press-fitting tool b23 with the second positioning tool 22, the coaxiality error between the spring disk and the damper 100 is controlled within ±0.05mm. Compared with the positioning deviation caused by manual assembly relying on experience and judgment, which is usually ≥±0.3mm, the automation system can feedback the position information in real time through the encoder to ensure that the parallelism of the fitting surface between the spring disk and the upper and lower support seats meets the standard, thereby avoiding abnormal noise or life reduction problems of the product caused by uneven distribution of preload force.

[0049] It should be noted that the matching structure of the pressure head A232 and the upper surface of the front spring plate allows for precise docking, avoiding installation difficulties caused by misalignment or tilting during assembly. This ensures that the pressure head maintains vertical alignment with the end cap when applying pressure, reducing unbalanced loading, thereby improving assembly accuracy and system stability. Furthermore, the structurally matched pressure head provides more even force during use, reducing wear or deformation caused by stress concentration, thereby extending the service life of the equipment.

[0050] The press b231 is driven either automatically or manually. The pressing tool b23 is installed on the vertical part of the bracket b221 through a locking piece 24. The locking piece 24 includes a second sliding frame 241 connected to the press b231. The second sliding frame 241 moves vertically on the bracket b221 in the form of a pulley rail. The bracket b221 is provided with a plurality of positioning holes 226220 in the vertical direction. The second sliding frame 241 is installed on the positioning hole 226 through a second positioning bolt 225. A placement rack b24 is provided on one side of the working platform b21, and a plurality of storage frames b25 are placed on the placement rack b24.

[0051] Further, if Figure 8-10 As shown, the carrier a32 includes a mounting cylinder a323 rotatably mounted on a rotating seat a322 via a rotating shaft a321 and a rotating rod a324 of a right-angle structure disposed at the lower end of the mounting cylinder a323 . The damper is matingly inserted into the mounting cylinder a323 . The righting assembly a33 includes a positioning assembly a331 provided on one side of the carrier a32 and a clamping assembly a332 located above the positioning assembly a331. The positioning assembly a331 includes a pneumatic unit a3321, a push plate a3323 connected to the telescopic end of the pneumatic unit a3321 and movable within the position of the bayonet c3322 on the rotating rod a324. The telescopic end of the pneumatic unit a3321 is elastically connected to the rotating seat a322. The clamping assembly a332 includes a clamping seat a3324 that slides vertically on the working platform c31 in the manner of a pulley rail, and a pneumatic gripper a3325 mounted on the clamping seat a3324. The press-fitting tool c34 includes a press c341 and a pressing head b343 that is raised and lowered on a mounting frame a342 under the drive of the press c341.

[0052] In this application, by setting up a carrier a32 in conjunction with the straightening component a33, the damper can be quickly loaded into the carrier a32 in an inclined state, and the straightening component a33 straightens it after installation and positioning to keep it in a vertical state. Since the damper is heavy and long, the clamping component a332 is used to clamp and position the damper body, and then the press c341 applies pressure stably and accurately to complete the press installation.

[0053] Further, if Figure 12-14 As shown, the carrier b42 includes a base a422 with a rotation groove 421, a mounting frame b423 mounted on the base a422, a clamping unit a424 fixedly mounted on the mounting frame b423, a clamping unit b426 rotatably arranged on the mounting frame b423 via a rotation axis b425, and a mounting cylinder b427 mounted on the base a422 and located between the clamping unit a424 and the clamping unit b426. The lower end of the clamping unit b426 is located in the rotation groove 421 and includes a right-angled bayonet d428 at its lower end. A gap is set between the lower end of the clamping unit b426 and the outer end of the rotation groove 421. A straightening assembly b43, comprising a pneumatic unit b431 and a push plate b432 connected to an output end of the pneumatic unit b431, wherein the output end of the push plate b432 is matingly inserted into the bayonet d428; and The press-fitting tool d44 includes a press d441 and a pressing head c442 that rises and falls under the drive of the press d441.

[0054] In this application, by setting up a rotatable carrier b42, it is convenient to quickly insert and install the tower top nuts and vibration isolation rubber blocks during manual loading, so as to reduce the requirements for operators of different heights, and dampers with excessive size are also easy to operate. Assisted by the straightening component b43, the carrier b42 remains in a vertical state during the processing, thereby ensuring the accuracy of the processing. Special and intelligent tooling ensures high precision and consistency, thereby improving product quality.

[0055] It should be noted that by setting up the straightening component b43, on the one hand, when the damper is loaded, the clamping unit b426 can be opened and rotated to a suitable position, and the damper can be placed on the clamping unit b426 and straightened. The straightening component b43 is inserted under the clamping unit b426, and the clamping unit b426 cooperates with the clamping unit a424 to clamp the damper, so that its positioning during assembly is more accurate.

[0056] A limiting member a443 is installed on the base a422, and the limiting member a443 is arranged on the other side of the clamping unit b426 relative to the straightening assembly b43, limiting the rotating clamping unit b426 and limiting the extreme position of the rotation of the clamping unit b426. A discharge box 45 for placing nuts is provided on the working platform d41, and a tightening assembly b46 is also provided directly above the carrier b42. The tightening assembly b46 includes a balancing hanger, a screw gun control system 461 and a screw gun operating system b462.

[0057] Further, if Figure 15-17 As shown, the upper end of the carrier c52 is a concave structure and is adapted to the shape of the yoke 300; The splitting assembly 53 includes a base b531 and a splitting rod 532 slidably disposed on the base b531 , wherein the end of the splitting rod 532 is a triangular structure; The positioning assembly a54 includes a pneumatic unit c542 mounted on a base c541 and a positioning column a543 disposed at the end of the pneumatic unit c542 and adapted to the yoke circular opening 400; The tightening assembly a55 includes a base d551 and a screw gun 552 installed on the base d551 in a pulley slide manner.

[0058] A clamping assembly b56 is also provided behind the splitting assembly 53. The clamping assembly b56 includes a clamping seat b561 that slides vertically on the working platform e51 in the form of a pulley slide rail and a pneumatic clamp b562 installed on the clamping seat b561. A press e57 is also provided above the carrier c52. The press e57 includes a pressure head d571 and a laser micrometer arranged on one side of the pressure head d571. A detection camera is provided on one side of the carrier c52. A nut storage rack 58 and a bolt storage rack 59 are installed on the working platform e51.

[0059] It should be noted that before the yoke is tightened by the nut, the yoke movable mouth needs to be opened by the splitting component 53 to make its state position unique, which is convenient for the subsequent installation of bolts and nuts, and then the triangular structure at the end of the splitting rod 532 is used to gradually open the yoke movable mouth quickly and stably.

[0060] Among them, the damper is positioned and straightened by setting the clamping component b56, and then the positioning component a54 below is used to position and fix the yoke to improve the accuracy of assembly.

[0061] In the present application, the carrier c52, the splitting assembly 53 and the positioning assembly a54 are provided to cooperate in limiting the yoke 300, and the clamping assembly b56 is used to limit the damper. When the yoke and the damper are assembled, the processing tooling can accurately position and fix the workpiece to ensure the consistency of size and position during the processing, thereby improving the quality and consistency of the finished product. In addition, the front yoke serves as a key connecting component between the shock absorber and the frame body, and the high precision and quality of its assembly are used to ensure the overall rigidity of the shock absorber system and the stability of the vibration transmission path.

[0062] Further, if Figure 1 As shown, a transport trolley 9 for transporting the damper 100 is also included.

[0063] It should be noted that the transfer between the various devices needs to be carried out through the transfer trolley 9.
