Technical Field

[0001] This invention relates to the field of vehicle manufacturing technology, and more particularly to an assembly device. Background Technology

[0002] In vehicle production, the brake assembly needs to be assembled, which involves putting the brake disc, shock absorber, control arm, and bracket together. The brake disc is secured to the shock absorber by screws, and the shock absorber is fixed to the brake disc by lock nuts. The control arm is also secured to the brake disc by locking nuts, and the bracket is installed on the control arm by fixing bolts and their matching nuts. However, assembling the brake assembly presents a technical challenge of low work efficiency.

[0003] Therefore, it is necessary to provide a new assembly equipment to solve the above-mentioned technical problems. Summary of the Invention

[0004] The main objective of this invention is to provide an assembly device that addresses the technical problem of low work efficiency during the assembly of brake assemblies.

[0016] In one embodiment, the conveying assembly includes a first conveying unit and a second conveying unit spaced apart along a first direction, the second conveying unit being slidably disposed on the frame along a second direction, the frame being provided with a drive cylinder, and the bearing assembly having a retraction position;

[0017] Both the first conveying unit and the second conveying unit can drive the carrying component to move along the first direction to the feeding position; when the carrying component is in the feeding position, the carrying component is placed in the second conveying unit, and the drive cylinder can drive the second conveying unit to move along the second direction, so as to drive the carrying component to switch between the feeding position and the recycling position.

[0018] In one embodiment, the feeding device includes a pushing mechanism disposed above the feeding station and a feeding mechanism disposed on one side of the feeding station. The pushing mechanism includes a cylinder and a push rod telescopically disposed in the cylinder. The feeding mechanism includes a vibratory feeder and a conveying pipe connected to the vibratory feeder. One end of the conveying pipe is connected to the cylinder and forms a discharge port. The push rod can pass through the discharge port to push the locking nut to the screw.

[0019] The end of the push rod that passes through the discharge port has a stepped portion that can be inserted into the locking nut.

[0020] In one embodiment, the feeding mechanism further includes a sealing assembly, which includes a rotating shaft, a torsion spring, and a sealing plate. The rotating shaft is disposed on one side of the discharge port. The sealing plate is movably disposed at the discharge port to open or close the discharge port. The two ends of the torsion spring are respectively connected to the conveying pipe and the sealing plate.

[0021] In one embodiment, the feeding device further includes a first adjusting mechanism, which can drive the pushing mechanism to move in a third and a fourth direction.

[0022] In one embodiment, the tightening device includes a second transfer robot, a quick-change assembly, and a tightening component.

The tightening device can tighten the locking nut and the locking nut to fix the position of the shock absorber and the swing arm. The tightening machine can tighten the fixing bolt and its matching nut to fix the bracket to the swing arm. Specifically, during brake assembly assembly, the brake assembly sequentially passes through a loading station, a feeding station, and a tightening station. While the brake assembly is at the loading station, a first transfer robot transports the shock absorber from the load-bearing mechanism to the tightening mechanism for tightening. After the shock absorber's fastening nut is tightened, the shock absorber is transferred to the brake disc at the loading station. While the brake assembly passes through the feeding station, the feeding device pushes the locking nut to the screw on the brake disc. While the brake assembly passes through the tightening station, the tightening device tightens the locking nut and the locking bolt to fix the shock absorber and the control arm to the brake disc. Subsequently, the tightening machine tightens the fixing bolts and their matching fixing nuts to fix the bracket to the control arm, thus completing the brake assembly assembly. This assembly equipment can replace manual labor in brake assembly, improving work efficiency. This assembly equipment is applied in the field of vehicle production technology.

[0050] Please see Figure 13 In the vehicle production process, a brake assembly 600 needs to be assembled, which involves combining the brake disc 620, shock absorber 610, control arm 630, and bracket 640. The screw 621 on the brake disc 620 passes through the shock absorber 610, and the shock absorber 610 is fixed to the brake disc 620 by a lock nut 611. The control arm 630 is fixed to the brake disc 620 by a locking nut 631, and the bracket 640 is installed on the control arm 630 by fixing bolts 641 and their matching fixing nuts. In actual work, researchers have found that the assembly and tightening of the various parts of the brake assembly 600 are currently mainly done manually (e.g., assembling the brake disc 620 and shock absorber 610, tightening the lock nut 611, tightening the locking nut 631, and tightening the fixing bolts 641 and their matching fixing nuts), which is inefficient.

[0051] This invention proposes an assembly device for assembling a brake assembly 600, aiming to solve the technical problem of low work efficiency in assembling the brake assembly 600.

[0052] Please see Figure 1 and Figure 2In one embodiment of the present invention, the assembly equipment includes a production line 100, an assembly device 200, a feeding device 300, a tightening device 400, and a tightening machine 500. The production line 100 is sequentially provided with a loading station 110, a feeding station 120, and a tightening station 130 along its conveying direction. The assembly device 200 is located on one side of the loading station 110. The assembly device 200 includes a carrying mechanism 210, a tightening mechanism 220, and a first transfer robot 230. The first transfer robot 230 can transfer the shock absorber 610 from the carrying mechanism 210 to the tightening mechanism 220, and the tightening mechanism 220 tightens the shock absorber 610. The tightening nut also allows the shock absorber 610, tightened by the tightening mechanism 220, to be transferred to the brake disc 620 at the loading station 110. The feeding device 300 is located on one side of the feeding station 120 and is used to feed the locking nut 611 to the screw 621 passing through the shock absorber 610 on the brake disc 620. The tightening device 400 is located on one side of the tightening station 130 and is used to tighten the locking nut 611 and the locking nut 631 of the fixed swing arm 630. The tightening machine 500 is located on the other side of the tightening station 130 and is used to tighten the fixing bolts 641 of the fixed bracket 640 and their matching fixing nuts.

[0053] The technical solution of this invention, by setting up an assembly device 200, a feeding device 300, a tightening device 400, and a tightening machine 500, can replace manual labor in assembling the brake assembly 600, thereby improving work efficiency. In this embodiment, the assembly device 200 can tighten the fastening nut of the shock absorber 610 and complete the pre-assembly of the shock absorber 610 and the brake disc 620. The feeding device 300 can push the washer and the locking nut 611 sequentially to the screw 621 of the brake disc 620. The tightening device 400 can tighten the locking nut 611 and the locking nut 631 to fix the position of the shock absorber 610 and the swing arm 630. The tightening machine 500 can tighten the fixing bolt 641 and its matching nut to fix the bracket 640 to the swing arm 630. Specifically, when assembling the brake assembly 600, the brake assembly 600 will sequentially pass through the loading station 110, the feeding station 120, and the tightening station 130. When the brake assembly 600 is at the loading station 110, the first transfer robot 230 will transfer the shock absorber 610 from the carrying mechanism 210 to the tightening mechanism 220 for tightening, and after the fastening nut of the shock absorber 610 is tightened, the shock absorber will be transferred to the brake disc 620 at the loading station 110. When the brake assembly 600 passes through the feeding station 120... During assembly, the feeding device 300 pushes the locking nut 611 to the screw 621 of the brake disc 620; when the brake assembly 600 passes the tightening station 130, the tightening device 400 tightens the locking nut 611 and the locking nut 631 to fix the shock absorber 610 and the swing arm 630 to the brake disc 620. Subsequently, the tightening machine 500 tightens the fixing bolt 641 and its matching fixing nut to fix the bracket 640 to the swing arm 630, thus completing the assembly of the brake assembly 600. This assembly equipment can replace manual labor in assembling the brake assembly 600, improving work efficiency. This assembly equipment is applied in the field of vehicle production technology.

[0054] Please see Figure 2 and Figure 3 In one embodiment of the present invention, the tightening mechanism 220 includes a mounting frame 221, a tightening assembly 222, a clamping member 223, and a locking assembly 224 sequentially disposed on the mounting frame 221. In this embodiment, the clamping member 223 may be a structure in which a bidirectional drive cylinder cooperates with two clamping blocks. Specifically, the bidirectional drive cylinder can drive the two clamping blocks to move in a direction that approaches or moves away from each other, so as to clamp or release the shock absorber 610. In a specific embodiment, the sides of the two clamping blocks facing each other are each formed with an arc-shaped surface adapted to the outer surface of the shock absorber 610.

[0055] The locking assembly 224 includes a positioning pin 2241 and a locking member 2242. The locking member 2242 has a clearance groove 2243. The positioning pin 2241 is accommodated in the clearance groove 2243 and can pass through the mounting hole of the shock absorber 610. In this embodiment, the locking member 2242 can also be a structure in which a bidirectional drive cylinder cooperates with two clamping blocks, which is similar to the structure of the clamping member 223 and will not be described in detail here. The clamping member 223 is used to clamp the middle part of the shock absorber 610, and the locking member 2242 is used to clamp the end of the shock absorber 610. The positioning pin 2241 can pass through the mounting hole at the end of the shock absorber 610 to prevent the shock absorber 610 from rotating; the clearance groove 2243 allows the positioning pin 2241 to pass through to prevent the positioning pin 2241 from interfering with the locking member 2242. In one specific embodiment, the diameter of the locating pin 2241 is slightly smaller than the diameter of the mounting hole at the end of the shock absorber 610, and the difference between the two diameters is 0.1 mm.

[0056] The tightening assembly 222 includes a drive member 2221, a mounting base 2222 slidably disposed on the mounting bracket 221, and a first tightening gun 2223 disposed on the mounting base 2222. The first tightening gun 2223 is provided with a first tightening sleeve adapted to fasten the nut. The drive member 2221 can drive the mounting base 2222 to move toward or away from the clamping member 223, thereby driving the first tightening gun 2223 to move toward or away from the clamping member 223. Specifically, when tightening the fastening nut of the shock absorber 610, firstly, the clamping member 223 and the locking assembly 224 are controlled to clamp the shock absorber 610; then, the driving member 2221 is controlled to drive the mounting base 2222 to move towards the clamping member 223, which in turn drives the first tightening gun 2223 to move towards the clamping member 223, until the first tightening sleeve on the first tightening gun 2223 is fitted onto the fastening nut; finally, the first tightening gun 2223 is controlled to run, and the first tightening sleeve is driven to rotate by the first tightening gun 2223, which in turn drives the fastening nut to rotate, thereby tightening the fastening nut. After the fastening nut of the shock absorber 610 is tightened, the drive component 2221 is first controlled to drive the mounting base 2222 to move away from the clamping component 223, thereby driving the first tightening gun 2223 to move away from the clamping component 223 until the first tightening sleeve disengages from the fastening nut. Then, the clamping component 223 and the locking assembly 224 are controlled to release the shock absorber 610. At this time, the shock absorber 610 can be transferred by the first transfer robot 230 to the brake disc 620 at the loading station 110. In a specific embodiment, the drive component 2221 can be a drive cylinder or a drive hydraulic cylinder, and the structure of the first tightening gun 2223 can refer to existing electric tightening guns.

[0057] In this embodiment, the mounting base 2222 is slidably disposed on the mounting frame 221 via a combination of slide rails and sliders. Specifically, there are two slide rails, spaced apart on the mounting frame 221, and each slide rail is provided with two corresponding sliders. The mounting frame 221 is provided with a limiting block that can abut against the mounting base 2222, which is used to limit the position of the mounting base 2222. Specifically, when the driving member 2221 drives the mounting base 2222 to move away from the clamping assembly, the limiting block can abut against the mounting base 2222 to limit the position of the mounting base 2222. In addition, a positioning plate 2231 is provided above the clamping member 223, and the positioning plate 2231 has a positioning groove 2232 for accommodating the shock absorber 610; wherein, the positioning groove 2232 can pre-position the shock absorber 610 when the clamping member 223 clamps the shock absorber 610 to ensure the accurate position of the shock absorber 610.

[0058] Please see Figure 4 and Figure 5 In one embodiment of the present invention, the supporting mechanism 210 includes a frame 211, a conveying assembly 212, and a supporting assembly 213. The conveying assembly 212 is disposed on the frame 211, and the supporting assembly 213 includes a pallet 2131 placed on the conveying assembly 212 and a positioning block 2132 disposed on the pallet 2131. The positioning block 2132 has a positioning hole 2133 for the shock absorber 610 to be inserted. The supporting assembly 213 has a loading position, and the conveying assembly 212 can drive the supporting assembly 213 to move to the loading position. Specifically, the conveying assembly 212 is disposed on the frame 211 and can drive the supporting assembly 213 placed on it to move to the loading position. The carrying component 213 includes a pallet 2131 and a positioning block 2132. The pallet 2131 is placed on the conveying component 212, and the positioning block 2132 is used to place the shock absorber 610. By opening a positioning hole 2133 on the positioning block 2132 for the shock absorber 610 to be inserted, the shock absorber 610 can be positioned and fixed, thereby preventing the shock absorber 610 from shaking during the conveying process, so that the transfer robot can grab the shock absorber 610.

[0059] In this embodiment, there are multiple positioning blocks 2132 arranged in a rectangular array on the support plate 2131, and each positioning block 2132 has a positioning hole 2133. Each positioning hole 2133 has two opposing first positioning surfaces, and the end of the shock absorber 610 inserted into the positioning hole 2133 has two opposing second positioning surfaces, with the two first positioning surfaces and the two second positioning surfaces corresponding and fitting together. Furthermore, each positioning block 2132 is provided with two positioning rods 2134 spaced apart, and a clamping gap is provided between the two positioning rods 2134. Through the cooperation of the positioning rods 2134 and the positioning surfaces (the line connecting the two first positioning surfaces is perpendicular to the line connecting the two positioning rods 2134), the shock absorber 610 can be positioned in two directions to prevent the shock absorber 610 from shaking. In a specific embodiment, a reinforcing rod 2135 is provided between the two positioning rods 2134 of two adjacent positioning blocks 2132 that are close to each other.

[0060] Please see Figure 4 In one embodiment of the present invention, the conveying assembly 212 includes a first conveying unit 2121 and a second conveying unit 2122 spaced apart along a first direction. The second conveying unit 2122 is slidably disposed on a frame 211 along a second direction. The frame 211 is provided with a drive cylinder 2111, and the carrying assembly 213 has a retraction position. Both the first conveying unit 2121 and the second conveying unit 2122 can drive the carrying assembly 213 to move along the first direction to the loading position. When the carrying assembly 213 is in the loading position, the carrying assembly 213 is placed on the second conveying unit 2122, and the drive cylinder 2111 can drive the second conveying unit 2122 to move along the second direction, thereby driving the carrying assembly 213 to switch between the loading position and the retraction position. The first direction is... Figure 4 The direction indicated by X in the diagram, the second direction is Figure 4 The direction indicated by Z in the diagram. Specifically, the carrying component 213 can move along the first direction to the loading position under the drive of the first conveying unit 2121 and the second conveying unit 2122; after the first transfer robot 230 has finished grabbing the shock absorber 610 on the carrying component 213, the drive cylinder 2111 can drive the second conveying unit 2122 to move along the second direction, thereby driving the carrying component 213 from the loading position to the recycling position. Subsequently, the second conveying unit 2122 can drive the carrying component 213 to move in the opposite direction of the first direction, so that the emptied carrying component 213 can leave the recycling position. In a specific embodiment, a recycling component is provided on one side of the recycling position. The recycling component includes multiple recycling rollers arranged sequentially from low to high along the first direction; specifically, after the emptied carrying component 213 leaves the recycling position, it will slide down the recycling component to the bottom, at which time the worker can recycle the emptied carrying component 213.

[0061] In this embodiment, both the first conveying unit 2121 and the second conveying unit 2122 include a plurality of conveying rollers spaced apart along a first direction. The plurality of conveying rollers of the first conveying unit 2121 are connected by a synchronous belt drive and driven by a drive motor. Each conveying roller of the second conveying unit 2122 is provided with a corresponding drive motor.

[0062] Please see Figures 6 to 8 In one embodiment of the present invention, the feeding device 300 includes a pushing mechanism 310 disposed above the feeding station 120 and a feeding mechanism 320 disposed on one side of the feeding station 120. The pushing mechanism 310 includes a cylinder 311 and a push rod 312 telescopically disposed in the cylinder 311. The feeding mechanism 320 includes a vibratory feeder and a conveying pipe 321 connected to the vibratory feeder. One end of the conveying pipe 321 is connected to the cylinder 311 and forms a discharge port 322. The push rod 312 can pass through the discharge port 322 to push the locking nut 611 to the screw 621. In this embodiment, the vibratory feeder is used to convey the gasket and the locking nut 611 to the discharge port 322 through the conveying pipe 321, and the push rod 312 can pass through the discharge port 322 and push the gasket and the locking nut 611 at the discharge port 322 to the screw 621 of the brake disc 620. Specifically, the process of fitting the gasket and locking nut 611 onto the screw 621 of the brake disc 620 is as follows: First, the feeding mechanism 320 conveys the gasket and locking nut 611 to the discharge port 322 through the conveying pipe 321. Then, the push rod 312 of the pushing mechanism 310 moves rapidly towards the feeding station 120. During this process, the push rod 312 pushes the gasket and locking nut 611 at the discharge port 322 directly above the screw 621 of the brake disc 620. Subsequently, the push rod 312 moves rapidly away from the feeding station 120. At this time, due to inertia, the gasket and locking nut 611 do not return with the push rod 312, but remain directly above the screw 621. Finally, under their own weight, they fall downwards and fit onto the screw 621 of the brake disc 620. In a specific embodiment, the pushing mechanism 310 is inclined. The end of the push rod 312 that passes through the discharge port 322 has a stepped portion 3121 that can be inserted into the locking nut 611. In this embodiment, when the push rod 312 passes through the discharge port 322, the stepped portion 3121 formed on the push rod 312 will be inserted into the center hole of the washer and the locking nut 611, which can prevent the washer and the locking nut 611 from falling off the push rod 312.

[0063] In one specific embodiment, there are four vibratory feeders, four conveying pipes 321, and four feeding mechanisms 320. These are arranged in a one-to-one correspondence, and there are two feeding stations 120. The four feeding mechanisms 320 are arranged in pairs above the two feeding stations 120. Two of the four vibratory feeders respectively feed a pad and a locking nut 611 to the two feeding mechanisms 320 above one of the feeding stations 120, and the other two vibratory feeders respectively feed a pad and a locking nut 611 to the two feeding mechanisms 320 above the other feeding station 120. Specifically, in use, by setting a corresponding program, the push rod 312 of the pushing mechanism 310 first feeds the pad to the screw 621 of the brake disc 620, and then feeds the locking nut 611 to the screw 621 of the brake disc 620.

[0064] Please see Figure 8 In one embodiment of the present invention, the feeding mechanism 320 further includes a blocking assembly 330, which includes a rotating shaft 331, a torsion spring 332, and a blocking plate 333. The rotating shaft 331 is disposed on one side of the discharge port 322; the blocking plate 333 is movably disposed at the discharge port 322 to open or close the discharge port 322; the two ends of the torsion spring 332 are respectively connected to the conveying pipe 321 and the blocking plate 333. In this embodiment, the blocking assembly 330 is used to open or close the discharge port 322. Specifically, when the push rod 312 of the pushing mechanism 310 has not passed through the discharge port 322, that is, when the push rod 312 is disengaged from the conveying pipe 321, so that the feeding mechanism 320 conveys the gasket and locking nut 611 to the discharge port 322, the sealing plate 333 can move under the action of the torsion spring 332 and close the discharge port 322 to prevent the gasket and locking nut 611 from falling out of the discharge port 322; when the push rod 312 of the pushing mechanism 310 moves towards the feeding station 120, the push rod 312 will overcome the force of the torsion spring 332 and push the sealing plate 333 to move and open the discharge port 322. At this time, the push rod 312 can push the gasket and locking nut 611 at the discharge port 322 to the screw 621 of the brake disc 620. In a specific embodiment, the sealing plate 333 has a groove 3331 for the push rod 312 to pass through.

[0065] In one embodiment of the present invention, the feeding device 300 further includes a first adjusting mechanism 340, which can drive the pushing mechanism 310 to move along a third direction and a fourth direction. The third direction is... Figure 7 The direction indicated by M in the diagram, the fourth direction is Figure 7The direction indicated by N in the diagram. Specifically, the first adjustment mechanism 340 can drive the pushing mechanism 310 to move along the third and fourth directions to ensure that when the push rod 312 extends, its end (i.e., the stepped portion 3121) is located above the screw 621 of the brake disc 620, thereby ensuring that the pushing mechanism 310 can push the washer and locking nut 611 to the screw 621 of the brake disc 620. In a specific embodiment, the first adjustment mechanism 340 includes a first seat body slidably disposed along the third direction, a first drive motor capable of driving the first seat body to slide along the third direction, a second seat body slidably disposed along the fourth direction, and a second drive motor capable of driving the second seat body to slide along the fourth direction, with the pushing mechanism 310 disposed on the second seat body.

[0066] Please see Figure 9In one embodiment of the present invention, the tightening device 400 includes a second transfer robot 410, a quick-change assembly 420, and a tightening member 430. The tightening member 430 is disposed on the second transfer robot 410. The quick-change assembly 420 includes a first retainer 421, a first tightening head 422 engaged with the first retainer 421, a second retainer 423, and a second tightening head 424 engaged with the second retainer 423. The second transfer robot 410 can transfer the tightening member 430 and tighten the tightening member 430. 30 is engaged with either the first tightening head 422 or the second tightening head 424; when the tightening part 430 is engaged with the first tightening head 422, the second transfer robot 410 can transfer the tightening part 430 to the locking nut 611, and the tightening part 430 tightens the locking nut 611; when the tightening part 430 is engaged with the second tightening head 424, the second transfer robot 410 can transfer the tightening part 430 to the locking nut 631, and the tightening part 430 tightens the locking nut 631. In this embodiment, the second transfer robot 410 can transfer the tightening component 430 so that the tightening component 430 can engage with the first tightening head 422 or the second tightening head 424 to replace the tightening head of the tightening component 430; at the same time, when the tightening component 430 is engaged with different tightening heads, it can also transfer the tightening component 430 to different positions to tighten the locking nut 611 of the fixed shock absorber 610 or the locking nut 631 of the fixed swing arm 630. Specifically, when tightening the locking nut 611 of the shock absorber 610, the second transfer robot 410 is first controlled to transfer the tightening component 430 and engage it with the first tightening head 422. Then, the second transfer robot 410 is controlled to transfer the tightening component 430 to the locking nut 611 at the tightening station 130, until the first tightening head 422 is fitted onto the locking nut 611. Finally, the tightening component 430 is controlled to rotate, driving the first tightening head 422 to rotate, thus rotating the locking nut 611 and tightening it, thereby fixing the shock absorber 610 to the brake disc 62. On the 0th, when tightening the locking nut 631 of the fixed swing arm 630, firstly, the second transfer robot 410 is controlled to transfer the tightening component 430 and engage it with the second tightening head 424. Then, the second transfer robot 410 is controlled to transfer the tightening component 430 to the locking nut 631 at the tightening station 130, until the second tightening head 424 is fitted onto the locking nut 631. Finally, the tightening component 430 is controlled to run, driving the second tightening head 424 to rotate, which in turn drives the locking nut 631 to rotate, tightening the locking nut 631 and fixing the swing arm 630 onto the brake disc 620. In a specific embodiment, the tightening component 430 can be a tightening gun.

[0067] In this embodiment, both the first tightening head 422 and the second tightening head 424 have annular grooves, and both the first retainer 421 and the second retainer 423 have semi-enclosed engaging portions that can engage with the corresponding annular grooves. The annular grooves and semi-enclosed engaging portions achieve engagement between the tightening head and the retainer, preventing the tightening head from disengaging from the retainer in the vertical direction, thus ensuring smooth engagement between the tightening head and the tightening gun. Both the first mounting bracket 421 and the second mounting bracket 423 are equipped with detection sensors to detect whether the tightening head has been removed. Specifically, when the first tightening head 422 is removed, the detection sensor on the first mounting bracket 421 transmits the detection information to an external controller. The external controller then controls the movement of the second transfer robot 410 based on the detection information, thereby transferring the tightening component 430 to the locking nut 611 at the tightening station 130 until the first tightening head 422 is fitted onto the locking nut 611. Finally, the robot controls the tightening component 430 to run, driving the first tightening head 422 to rotate, which in turn drives the locking nut 611 to rotate, tightening the locking nut 611 and fixing the shock absorber 610 to the brake disc 620. When the second tightening head 424 is removed, the second transfer robot 410 transfers the tightening component 430 to the locking nut 631 and tightens the locking nut 631.

[0068] In one specific embodiment, the tightening device 400 further includes a limiting component 440 and a base 411 for mounting the second transfer robot 410. The limiting component 440 includes a first limiting rod 441 and a second limiting rod 442. The second limiting rod 442 is telescopically disposed on the first limiting rod 441. The end of the first limiting rod 441 away from the second limiting rod 442 is rotatably connected to the base 411, and the end of the second limiting rod 442 away from the first limiting rod 441 is rotatably connected to the tightening member 430. Specifically, the second limiting rod 442 is telescopically disposed on the first limiting rod 441, and the second limiting rod 442 will not detach from the first limiting rod 441. By connecting the base 411 and the tightening member 430 through the first limiting rod 441 and the second limiting rod 442, the range of motion of the tightening member 430 can be limited.

[0069] Please see Figures 10 to 12 In one embodiment of the present invention, the tightening machine 500 includes a tightening unit 510 and an anti-rotation unit 520, which are arranged opposite to each other along a fifth direction. The tightening unit 510 includes a second tightening gun 511 that can move along the fifth direction, and the second tightening gun 511 is provided with a second tightening sleeve 5111 for inserting a fixing nut. The anti-rotation unit 521 includes a locking block 521 that can move along the fifth direction, and the locking block 521 has a locking hole for inserting the nut end of a fixing bolt 641. The fifth direction is... Figure 10The direction indicated by L in the figure. In this embodiment, the lock hole opened in the lock block 521 allows the nut end of the fixing bolt 641 to be inserted to prevent the fixing bolt 641 from rotating; the second tightening gun 511 can drive the fixing nut to rotate through the second tightening sleeve 5111 to tighten the fixing bolt 641 and its matching fixing nut, thereby fixing the swing arm 630 and the bracket 640 together.

[0070] In one specific embodiment, the locking block 521 is provided with a buffer spring 522 to provide cushioning. Specifically, the buffer spring 522 is sleeved on the guide rod 523. In another specific embodiment, the guide rod 523 is provided with a telescopic rod body 524, which passes through the lock hole. Both the rod body 524 and the guide rod 523 have oblong holes 525. A limiting rod 526 passes through the locking block 521 radially, and the limiting rod 526 passes through the oblong holes 525 of the guide rod 523 and the rod body 524 in sequence. When the limiting rod 526 abuts against the lower end of the oblong hole 525, it can limit the position of the locking block 521 and prevent the locking block 521 from disengaging from the guide rod 523. When the limiting rod 526 abuts against the upper end of the oblong hole 525, it can limit the position of the locking block 521 and prevent the buffer spring 522 from being damaged due to excessive movement of the locking block 521.

[0071] Please see Figure 10 In one embodiment of the present invention, the tightening machine 500 further includes a second adjusting mechanism 530, which can drive the tightening unit 510 and the anti-rotation unit 520 to move simultaneously along a sixth direction and a seventh direction. The sixth direction is... Figure 10 The direction indicated by K in the diagram, the seventh direction is Figure 10 The direction indicated by J in the diagram. Specifically, when tightening the fixing bolt 641 and its matching fixing nut connecting the swing arm 630 and the bracket 640, the second adjusting mechanism 530 first drives the tightening unit 510 and the anti-rotation unit 520 to move along the sixth and seventh directions, so that the anti-rotation unit 520 is aligned with the fixing bolt 641 and the tightening unit 510 is aligned with the fixing nut. Then, the anti-rotation unit 520 and the tightening unit 510 are controlled to move towards each other until the locking block 521 of the anti-rotation unit 520 is fitted onto the fixing bolt 641 and the second tightening sleeve 5111 of the tightening unit 510 is fitted onto the fixing nut. Finally, the second tightening gun 511 is controlled to run, driving the second tightening sleeve 5111 to rotate, which in turn drives the fixing nut to rotate, tightening the fixing bolt 641 and its matching fixing nut, and fixing the swing arm 630 and the bracket 640 together.

[0072] To ensure positioning accuracy during assembly, the assembly device 200, feeding device 300, tightening device 400, and tightening machine 500 are all equipped with cameras. Specifically, the camera in the assembly device 200 is used to acquire the position information of the screw 621 of the brake disc 620, the camera in the feeding device 300 is used to acquire the position information of the screw 621 of the brake disc 620, the camera in the tightening device 400 is used to acquire the position information of the locking nut 611 of the fixed shock absorber 610 or the locking nut 631 of the fixed swing arm 630, and the camera in the tightening machine 500 is used to acquire the position information of the fixing bolt 641 and its matching fixing nut.
