Description

Technical Field

[0001] This application relates to the technical field of vibration damper installation, and in particular to a device for installing vibration damper pads. Background Technology

[0002] Driven by the rapid development of the intelligent manufacturing equipment industry and the continuous expansion of the new energy vehicle market, the driving safety and comfort of new energy vehicles have become the core focus of industry competition. As a key component in the chassis suspension system of new energy vehicles, the performance of shock absorbers directly determines the vibration control effect during vehicle operation, and plays an irreplaceable role in improving the driving experience, protecting the vehicle body structure and extending the service life of the whole vehicle.

[0003] A shock absorber is a mechanical device that can suppress vibration and impact. By absorbing the vibration energy generated by uneven road surfaces during vehicle operation, it effectively attenuates the vibration response of the vehicle body and chassis. In the structural design of the shock absorber, in order to fill the gaps between components, reduce friction, and improve assembly stability, one or more shims are required in several key parts, such as the shock absorber's connecting rod. One end of the connecting rod is connected to the piston, and the other end is connected to the vehicle body. The connecting rod is prone to fretting wear during high-speed reciprocating motion. Shims need to be installed at the connection between the connecting rod and the vehicle body to effectively buffer vibration transmission and reduce direct contact wear between metal parts. After the shims are installed, nuts need to be installed and tightened to ensure that the shims do not shift or loosen under long-term dynamic loads.

[0004] In existing technologies, shim installation is mostly done manually with simple tooling. During the installation process, the operator needs to manually pick up and place the shims and position them, and then use tools such as wrenches to tighten the nuts. When installing multiple shims, problems such as missing shims or misalignment are likely to occur. Manual verification is difficult, resulting in unstable assembly quality and affecting the overall performance of the shock absorber.

[0005] Therefore, a device for installing shock absorber shims is needed to solve the problems of easy omissions and low installation accuracy when installing multiple shims in shock absorbers, thereby improving the automation and reliability of assembly. Summary of the Invention

[0006] To enable the quantity detection of installed gaskets, this application provides a device for installing shock absorber gaskets.

[0007] This application provides a device for installing shock absorber pads, which adopts the following technical solution: A device for installing shock absorber pads includes a device body, on which a conveying assembly and a pressing and detection mechanism are mounted. The conveying assembly is used to convey a product to the pressing and detection mechanism. The pressing and detection mechanism includes a lifting assembly, a pressing assembly, and a detection assembly. The lifting assembly is used to lift the product from the conveying assembly to a specified height. After the product is lifted to the specified height, the pressing assembly presses down on the pad on the product. The detection assembly moves down synchronously with the pressing assembly to monitor the relative displacement of the pad.

[0008] By adopting the above technical solution, the conveying component stably transports the product with completed gasket assembly to the pressing and testing mechanism. The lifting component first detaches the product from the conveying component and lifts it to a preset height. Then, the pressing component moves downward to press the gasket on the product. At the same time, the testing component moves down synchronously with the pressing component to capture the relative displacement data of the gasket in real time during the pressing process. Based on the displacement change characteristics, it judges whether the gasket is installed in place and whether the quantity is complete, thereby realizing the detection of gasket assembly and effectively avoiding the problems of missing or misaligned installation.

[0009] Optionally, the lifting assembly includes a lifting frame, a lateral drive component, and a vertical drive component. The lateral drive component drives the lifting frame to move closer to or away from the product. The lateral drive component is fixedly mounted on the vertical drive component. The vertical drive component drives the lifting frame to rise and fall to lift or lower the product.

[0010] By adopting the above technical solution, the lateral drive component first drives the lifting frame to move horizontally, approaching and fitting the product on the conveying component to complete the lateral positioning of the product. Then, the vertical drive component drives the lateral drive component and the lifting frame to lift the product from the conveying component to the designated height. After the pressing test is completed, the vertical drive component reverses its movement to lower the product, and the lateral drive component then drives the lifting frame to reset, completing one cycle of operation. Through the coordinated action of the lateral drive component and the vertical drive component, the product is lifted and accurately positioned, ensuring that the product is in a stable state during the testing process.

[0011] Optionally, the clamping assembly includes a pressure head and a clamping drive, wherein the clamping drive drives the pressure head to move up and down to clamp the pad.

[0012] By adopting the above technical solution, the pressing drive drives the pressure head to press down vertically, so that the gasket can be stably displaced under force. The pressure applied by the pressure head to the gasket is uniform, ensuring that the gasket and the product fit tightly, making the assembly more secure and reliable.

[0013] Optionally, the detection component includes an initial displacement sensor, an end displacement sensor, and a processing unit. The initial displacement sensor is used to detect the initial position of the pad before the pressure head is pressed down, and the end displacement sensor is used to detect the final position of the pad after the pressure head is pressed down. The processing unit receives the initial and final positions of the pad and determines whether the number of pads is correct.

[0014] By adopting the above technical solution, during the process of the pressure head pressing the gasket, the initial displacement sensor and the end displacement sensor collect the displacement data of the gasket from the initial state to the pressed position in real time, and transmit the displacement data in the form of electrical signals to the processing unit. The processing unit compares the actual displacement data with the displacement range of the corresponding standard gasket quantity to determine whether the number of gaskets on the current product meets the assembly requirements. The gasket pressing and quantity detection processes are carried out simultaneously to avoid errors caused by secondary positioning and improve the accuracy of gasket quantity detection.

[0015] Optionally, the clamping detection mechanism further includes a second limiting component, which includes a limiting rod and a limiting drive component. The device body is provided with a mounting plate for mounting the vertical drive component. The mounting plate has a through hole that slides with the limiting rod. The limiting drive component drives the limiting rod to insert into the through hole to limit the vertical displacement of the mounting plate.

[0016] By adopting the above technical solution, the second limiting component works in conjunction with the lifting component. When the vertical drive component of the lifting component lifts the product to a specified height, the limiting drive component drives the limiting rod to be inserted laterally into the through hole on the mounting plate. The limiting rod and the through hole form a rigid limiting fit, restricting the vertical displacement of the mounting plate and the vertical drive component. After the pressing test is completed, the limiting drive component drives the limiting rod to exit the through hole, releasing the limiting, and the vertical drive component can then lower the product, ensuring that the product maintains a stable height during the pressing test, thereby improving the accuracy of the gasket quantity detection.

[0017] Optionally, the device body is further equipped with a locking assembly for locking the pre-installed locking element on the product. The locking assembly includes a screw sleeve, a screw drive, and a lifting drive. The screw drive drives the screw sleeve to rotate to lock the locking element, and the lifting drive drives the screw drive to move up and down so that the screw sleeve is placed on or disengaged from the locking element.

[0018] By adopting the above technical solution, the lifting drive first drives the turning drive and the turning sleeve to descend, so that the turning sleeve is accurately fitted onto the product's locking component; then the turning drive starts, driving the turning sleeve to rotate, and locking the pre-installed locking component onto the product through threaded engagement; after locking is completed, the lifting drive drives the turning sleeve to rise, disengaging from the locking component and resetting, which enhances the connection stability between the locking component and the product and avoids the locking component from loosening or the gasket from being deformed due to uneven locking force.

[0019] Optionally, the conveying assembly includes a positioning seat, a forward conveyor belt, and a reverse conveyor belt. The positioning seat is used to place the product, and the forward conveyor belt and the reverse conveyor belt have opposite conveying directions to either convey the positioning seat in the forward direction or drive the positioning seat to reset in the reverse direction.

[0020] By adopting the above technical solution, the positioning seat ensures the positional accuracy of the product during the conveying process. When the forward conveyor belt is running, it drives the positioning seat and the product to the working position such as the pressing and testing mechanism. After the product completes all the processes, the reverse conveyor belt runs, driving the unloaded positioning seat to return to the initial loading position in the reverse direction, waiting for the next round of assembly operations.

[0021] Optionally, the device body is further provided with a switching component, which includes a push block and a switching drive component. The switching drive component drives the push block to move laterally to push the positioning seat to switch positions between the positive conveyor belt and the negative conveyor belt.

[0022] By adopting the above technical solution, when the positioning seat is conveyed to the designated position by the forward conveyor belt, the switching drive unit drives the push block to move laterally. The push block acts on the side of the positioning seat, pushing the positioning seat from the forward conveyor belt to the surface of the reverse conveyor belt. After the positioning seat reaches the initial working position, the positioning seat on the reverse conveyor belt is pushed back to the forward conveyor belt, thus starting a new round of product conveying, ensuring the smooth circulation of the conveying system, and also avoiding the accumulation of positioning seats at the ends of the forward and reverse conveyor belts.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. The conveying component stably transports the assembled gaskets to the pressing and testing mechanism. The lifting component first detaches the product from the conveying component and lifts it to a preset height. Then, the pressing component moves downward to press the gaskets on the product. At the same time, the testing component moves down synchronously with the pressing component to capture the relative displacement data of the gaskets in real time during the pressing process. Based on the displacement change characteristics, it judges whether the gaskets are installed in place and whether the quantity is complete, thereby realizing the detection of gasket assembly and effectively avoiding the problems of missing or misaligned installation. 2. The horizontal drive first drives the lifting frame to move horizontally, approaching and fitting the product on the conveying component to complete the horizontal positioning of the product. Then, the vertical drive drives the horizontal drive and the lifting frame to lift the product from the conveying component to the specified height. After the pressing test is completed, the vertical drive reverses its movement to lower the product, and the horizontal drive then drives the lifting frame to reset, completing one cycle. Through the coordinated action of the horizontal and vertical drive components, the product is lifted and accurately positioned, ensuring that the product is in a stable state during the testing process. 3. During the process of the pressure head pressing the gasket, the initial displacement sensor and the end displacement sensor collect the displacement data of the gasket from the initial state to the pressed position in real time, and transmit the displacement data in the form of electrical signals to the processing unit. The processing unit compares the actual displacement data with the displacement range of the corresponding standard gasket quantity to determine whether the number of gaskets on the current product meets the assembly requirements. The gasket pressing and quantity detection processes are carried out simultaneously to avoid errors caused by secondary positioning and improve the accuracy of gasket quantity detection.

[0026] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0027] Example: A device for mounting shock absorber pads, reference Figure 1 and Figure 2 The system includes a device body 1, on which a workbench 111 is mounted. The workbench 111 has several horizontally arranged stations for installing shims on vibration dampers. A conveying assembly 2 and a clamping and testing mechanism 3 are installed on the workbench 111. The conveying assembly 2 transports the vibration dampers with shims to be installed to each station. Workers install the shims onto the vibration dampers sequentially. The conveying assembly 2 then transports the vibration dampers with installed shims to the next station. The clamping and testing mechanism 3 is located on the workbench 111 and, in conjunction with… Figure 3The clamping and testing mechanism 3 includes a lifting component 311, a clamping component 321, and a testing component 331. The conveying component 2 transports the vibration damper with shims installed to the clamping and testing mechanism 3. The lifting component 311 first moves to the bottom of the vibration damper, and then moves upward to lift the vibration damper to a preset position. Subsequently, the clamping component 321 descends from above and, in cooperation with the lifting component 311, presses down on the multiple shims on the vibration damper. The shims slightly shift downward after being subjected to pressure to ensure that the multiple shims are tightly fitted. During the pressing process of the clamping component 321, the testing component 331 simultaneously collects the height change data of the shims and compares the collected data with the preset standard value. The data comparison results determine whether the shims are installed in place and whether the number of shims installed on the vibration damper meets the requirements. If the data is within the allowable range, the lifting component 311 moves down to release the vibration damper, and the conveying component 2 transports the vibration damper to the next station for subsequent assembly. If the data exceeds the allowable range, an alarm signal is issued to prompt the staff to immediately check the abnormal vibration damper.

[0028] refer to Figure 1 and Figure 4 A material rack 112 is provided on one side of the workbench 111. The equipment body 1 also includes a material picking module 113. The material picking module 113 includes a material box 114 and a material picking sensor 115. The material box 114 is used to place the pads. The material box 114 is installed on the material rack 112. Multiple material boxes 114 are evenly distributed along the direction of the vibration damper conveying, which makes it convenient for the staff to pick up the pads in the order of the workstation. The material picking sensor 115 is located at the opening of the material box 114. Whenever the staff takes out the pad from the material box 114, the material picking sensor 115 immediately records the picking action and feeds it back to the control system to ensure that the use of the pads at each workstation can be traced.

[0029] refer to Figure 2 and Figure 5 The conveying assembly 2 includes a positioning seat 211, a forward conveyor belt 221, and a reverse conveyor belt 231. The positioning seat 211 has a placement groove 212, the size and shape of which match the size and shape of the shock absorber. The placement groove 212 has a certain depth, which can effectively limit the shaking of the shock absorber during the conveying process. The forward conveyor belt 221 and the reverse conveyor belt 231 are symmetrically arranged on both sides of the workbench 111. The forward conveyor belt 221 and the reverse conveyor belt 231 rotate synchronously in opposite directions. In this embodiment, the forward conveyor belt 221 and the reverse conveyor belt 231 are belt conveyors, driven by a motor to realize the conveying function. The synchronous reverse rotation of the forward conveyor belt 221 and the reverse conveyor belt 231 is realized by using a gear transmission structure to ensure that the shock absorber is stably conveyed during the loading and unloading process, avoiding deviations and improving assembly accuracy and efficiency.

[0030] refer to Figure 2 and Figure 5The equipment body 1 is also equipped with a positive support edge 121 and a negative support edge 131. The positive support edge 121 and the negative support edge 131 are located outside the positive conveyor belt 221 and the negative conveyor belt 231, respectively. The positive conveyor belt 221 is located between the positive support edge 121 and the worktable 111. When the positioning seat 211 is conveyed on the positive conveyor belt 221, the edges of the positive support edge 121 and the worktable 111 limit the positioning seat 211, preventing the positioning seat 211 from shifting during the conveying process, and ensuring that the vibration damper is stably conveyed from the initial station to each assembly and testing station. At the workstation, after the vibration damper completes all assembly and testing procedures, it is removed from the positioning seat 211 and transferred to the next process. The reverse conveyor belt 231 is located between the reverse support edge 131 and the worktable 111. The unloaded positioning seat 211 is synchronously transported back to the initial workstation by the reverse conveyor belt 231. During the process of the unloaded positioning seat 211 returning to the initial workstation, the reverse support edge 131 and the edge of the worktable 111 also limit the positioning seat 211, ensuring that the unloaded positioning seat 211 returns to the initial workstation stably, preparing for the next cycle of assembly.

[0031] refer to Figure 2 and Figure 5 The workbench 111 has four stations arranged sequentially along the conveying direction of the vibration damper: a first assembly station 141, a second assembly station 151, an inspection station 161, and a locking station 171. The vibration damper is placed in the placement slot 212 of the positioning seat 211 and conveyed to the first assembly station 141 by the conveyor belt 221. The first assembly station 141 is equipped with a blocking block, which blocks the positioning seat 211, allowing it to stop precisely at the first assembly station 141, facilitating the installation of the first gasket by the workers. Figure 4 Workers assemble the gaskets from material box 114 into the designated positions on the vibration damper. When the gaskets are removed, the material sensor 115 records the action in real time and uploads it to the control system. After the gaskets are assembled, the first assembly station 141 is equipped with a first material sensor 1411. The first material sensor 1411 detects whether there are any omissions or misassemblies on the vibration damper and feeds the detection results back to the control system for judgment. Appropriate actions are taken for different situations. Then, the blocking block releases the positioning seat 211, and the conveyor belt 221 transports the vibration damper with the first gasket installed to the second assembly station 151.

[0032] refer to Figure 2 and Figure 5The positioning seat 211 is conveyed to the second assembly station 151 by the main conveyor belt 221. The second assembly station 151 is also equipped with a blocking block to ensure that the positioning seat 211 stops accurately, which facilitates the installation of the second pad by the workers. The workers take out the second pad from the corresponding material box 114 and assemble it into the designated position of the vibration damper. The second assembly station 151 is equipped with a second material sensor 1511. After the assembly is completed, the second material sensor 1511 of the second assembly station 151 detects the assembly result. After confirming that there are no omissions or misassemblies, it feeds the signal back to the control system. The system performs corresponding processing according to the instructions of the control system. If the detection is passed, the blocking block releases the positioning seat 211, and the vibration damper with the two pads installed continues to enter the detection station 161 by the main conveyor belt 221.

[0033] refer to Figure 2 and Figure 6 The testing station 161 is equipped with a first limiting component 1611, which includes a limiting cylinder 1612, a limiting baffle 1613, and a limiting sensor. When the vibration damper arrives at the testing station 161, the limiting sensor detects the positioning seat 211 in place, and the limiting cylinder 1612 drives the limiting baffle 1613 to extend. The limiting baffle 1613 has a limiting groove 1614 that matches the edge of the positioning seat 211. The limiting baffle 1613 extends and cooperates with the edge of the positioning seat 211 to achieve accurate positioning of the positioning seat 211, which facilitates subsequent testing of the pads on the vibration damper.

[0034] refer to Figure 2 and Figure 3 The lifting assembly 311, pressing assembly 321, and detection assembly 331 of the pressing and detection mechanism 3 are all located above the detection station 161. The lifting assembly 311 includes a lifting frame 312, a horizontal drive component 313, and a vertical drive component 314. The lifting frame 312 is provided with a U-shaped slot, which is adapted to the outer periphery of the shock absorber. In this embodiment, the horizontal drive component 313 and the vertical drive component 314 are both cylinders. The equipment body 1 is provided with a mounting plate 181. The horizontal drive component 313 is mounted on the mounting plate 181. Mounting plate 181 is fixedly connected, and lifting frame 312 is fixedly connected to the output shaft of horizontal drive component 313. Horizontal drive component 313 drives lifting frame 312 to move horizontally to directly below the shock absorber. The output end of vertical drive component 314 is fixedly connected to mounting plate 181. Vertical drive component 314 drives mounting plate 181, lifting frame 312 and horizontal drive component 313 to rise and fall synchronously. Lifting frame 312 rises so that U-shaped slots are engaged with the outer periphery of the shock absorber, so that the shock absorber is stably lifted to the detection height.

[0035] refer to Figure 2 and Figure 3The clamping assembly 321 includes a clamping drive 322 and a pressure head 323. The clamping drive 322 is a cylinder and is fixed on the mounting plate 181. The output end of the clamping drive 322 is fixedly connected to the pressure head 323. The clamping drive 322 drives the pressure head 323 to move vertically downward. After the pressure head 323 abuts against the pad on the shock absorber, it applies a set pressure to ensure that the pad is completely in place. The equipment body 1 is also equipped with a pressure regulating valve 191 to adjust the output pressure of the clamping drive 322 to ensure that the pressure applied during the assembly of shock absorbers of different specifications is appropriate and to avoid damage to the pad and shock absorber due to excessive pressure.

[0036] refer to Figure 3 and Figure 7 The pressing and detection mechanism 3 also includes a second limiting component 341, which includes a limiting rod 342 and a limiting drive component 343. In this embodiment, the limiting drive component 343 is a cylinder. The limiting rod 342 is fixedly connected to the output end of the limiting drive component 343. A through hole 182 is provided on the mounting plate 181. Before the driving pressure head 323 presses down on the pad, the limiting drive component 343 pushes the limiting rod 342 into the through hole 182. During the pressing process of the pressure head 323 pressing down on the pad, the pressure of the pressure head 323 is transmitted to the support frame 312 and then to the limiting rod 342 via the mounting plate 181. The reaction force of the limiting rod 342 on the mounting plate 181 achieves force balance, effectively preventing the damper from shifting during the pressing process and ensuring that the displacement of the pad remains accurate.

[0037] refer to Figure 1 and Figure 3 The detection component 331 includes an initial displacement sensor 332, an end displacement sensor 333, and a processing unit. The initial displacement sensor 332 is fixedly mounted on the device body 1 and is used to detect the initial position of the gasket before clamping. Figure 7 The endpoint displacement sensor 333 is installed above the pressure head 323 to detect the final position of the gasket after compression. The data from both are transmitted to the processing unit in real time for comparison and analysis. The number of gaskets assembled is judged based on the displacement change before and after compression. If the displacement change is within the set tolerance range, the number of gaskets assembled is judged to be correct and the test is qualified. If the displacement change exceeds the threshold, it is judged that there is a missing or overlapping assembly and the test is unqualified. The processing unit immediately issues an alarm signal and locks the current vibration damper. The staff will then conduct a manual re-inspection. After confirming the problem, the vibration damper will be reworked.

[0038] refer to Figure 1 and Figure 8 The equipment body 1 is also equipped with a locking assembly 4. After the gasket is pressed and the displacement is detected at the testing station 161, it is then combined with... Figure 2The shock absorber is placed back on the positioning seat 211 and continues to be conveyed forward by the conveyor belt 221 to the locking station 171. After reaching the locking station 171, the locking component is first pre-installed on the shock absorber stud by the operator, and then the pre-installed shock absorber is sent into the working area of ​​the locking assembly 4. The locking assembly 4 includes a screwing sleeve 411, a screwing drive component 412, and a lifting drive component 413. In this embodiment, the screwing drive component 412 is a servo motor, and the lifting drive component 413 is a cylinder. The screwing sleeve 411 is fixedly connected to the output shaft of the screwing drive component 412. The lifting drive component 413 drives the screwing drive component 412 and the screwing sleeve 411 to lift synchronously. The equipment body 1 is provided with a positioning hole adapted to the shock absorber. The positioning hole is located directly below the screwing sleeve 411. After the shock absorber is accurately placed into the positioning hole.

[0039] refer to Figure 8 and Figure 9 The device body 1 is equipped with a first positioning sensor 421 and a positioning fiber optic cable 431. The first positioning sensor 421 is used to detect whether there is a vibration damper in the positioning hole, and the positioning fiber optic cable 431 is used to confirm whether the locking component has been correctly pre-installed. When both the first positioning sensor 421 and the positioning fiber optic cable 431 return normal signals, the lifting drive 413 drives the screwing sleeve 411 to move downward until the screwing sleeve 411 is fitted onto the locking component. Then, the screwing drive 412 starts, driving the screwing sleeve 411 to rotate, precisely tightening the locking component and preventing the shim from falling off the vibration damper. After the locking component is tightened to the set torque, the screwing drive 412 stops driving the screwing sleeve 411, and the lifting drive 413 drives the screwing sleeve 411 to rise and reset. Figure 1 The equipment body 1 is also equipped with a finished product conveyor belt 6. After the shock absorber completes the locking process, it is automatically sent to the next process via the finished product conveyor belt 6. The entire assembly and testing process realizes automated continuous operation.

[0040] refer to Figure 1 and Figure 10 The device body 1 is also equipped with a switching component 5, which, in conjunction with... Figure 5The switching assembly 5 is located at both ends of the positive conveyor belt 221. After the vibration damper completes its work and the finished product conveyor belt 6 is placed in the position, the positioning seat 211 is in an unloaded state. The switching assembly 5 includes a push block 511 and a switching drive component 521. In this embodiment, the switching drive component 521 is a pneumatic push rod. The push block 511 is connected to the piston rod of the switching drive component 521. When the unloaded positioning seat 211 runs to the end with the positive conveyor belt 221, a second positioning sensor 531 is provided on the workbench 111 to detect the positioning signal of the unloaded positioning seat 211. The switching drive unit 521 drives the pusher block 511 to push the empty positioning seat 211 from the forward conveyor belt 221 to the reverse conveyor belt 231. The reverse conveyor belt 231 returns and sends the empty positioning seat 211 to the starting position. At the starting position, after the second positioning sensor 531 of the starting position detects the empty positioning seat 211, the switching drive unit 521 of the initial position of the worktable 111 is driven, and the pusher block 511 pushes the empty positioning seat 211 from the reverse conveyor belt 231 to the starting end of the forward conveyor belt 221, so that the positioning seat 211 re-enters the assembly cycle.

[0041] The implementation principle of this application embodiment is as follows: After the equipment is started, the vibration damper to be assembled is placed in the placement slot 212 of the positioning seat 211 and conveyed sequentially in the horizontal direction by the conveyor belt 221. First, at the first assembly station 141 and the second assembly station 151, the workers take the pads from the corresponding material boxes 114 and assemble them into the designated position of the vibration damper. The material picking sensor 115 records the material picking action in real time, and the material sensor simultaneously detects whether there is any omission or misassembly in the assembly. The vibration damper with two pads assembled enters the detection station 161. The limit cylinder 1612 drives the limit baffle 1613 to extend, and the limit groove 1614 cooperates with the edge of the positioning seat 211 to achieve precise positioning. Then, the lateral drive component 313 of the lifting component 311 drives the lifting frame 312 to move horizontally. When the device moves directly below the shock absorber, the vertical drive component 314 drives the lifting frame 312 to rise, stably lifting the shock absorber to the preset detection height. At the same time, the limit drive component 343 pushes the limit rod 342 into the through hole 182 of the mounting plate 181 to keep the shock absorber in a stable position. The pressing drive component 322 drives the pressure head 323 to move vertically downward, applying a set pressure to the pads on the shock absorber to make the pads fit tightly. During this process, the initial displacement sensor 332 and the final displacement sensor 333 collect the displacement change of the pads. The processing unit compares the displacement change with the preset standard value to determine whether the number of pads assembled is correct and whether the installation is in place. If the test is qualified, the lifting component 311 is reset and the shock absorber falls back to the positioning seat 211. If the test is unqualified, an alarm signal is issued and the device is locked for further investigation.

[0042] The qualified shock absorbers enter the locking station 171 along the forward conveyor belt 221. After manual pre-installation of the locking components, the lifting drive 413 drives the screwing sleeve 411 to move down and fit onto the locking components. The screwing drive 412 drives the screwing sleeve 411 to rotate, tightening the locking components to the set torque, completing the anti-detachment fixing of the shims. Then, the finished shock absorbers are sent out by the finished product conveyor belt 6. The unloaded positioning seat 211 runs to the end of the forward conveyor belt 221. The push block 511 pushes the positioning seat 211 to the reverse conveyor belt 231. The reverse conveyor belt 231 and the forward conveyor belt 221 rotate synchronously in opposite directions. Under the limiting action of the reverse support edge 131 and the edge of the workbench 111, the unloaded positioning seat 211 is transported back to the initial position of the workbench 111. Then, the push block 511 at the initial position of the workbench 111 pushes it to the starting end of the forward conveyor belt 221, re-entering the assembly cycle, realizing the continuous assembly, inspection and locking operation of the shock absorber shims.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
