In a specific embodiment, the two clamping blocks each have an arcuate surface on the facing side thereof that matches the outer surface of shock absorber 610.

[0055] The locking assembly 224 includes a positioning pin 2241 and a locking member 2242. The locking member 2242 is formed with an avoidance groove 2243. The positioning pin 2241 is accommodated in the avoidance groove 2243, and the positioning pin 2241 can be inserted into the mounting hole of the shock absorber 610. In this embodiment, the locking member 2242 can also be a structure composed of a two-way drive cylinder and two clamping blocks. Its structure is similar to that of the clamping member 223 and will not be repeated here. Among them, 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 be inserted into the mounting hole at the end of the shock absorber 610 to prevent the shock absorber 610 from rotating; the avoidance groove 2243 is for the positioning pin 2241 to pass through to prevent the positioning pin 2241 from interfering with the locking member 2242.

Specifically, when tightening the fastening nut of the shock absorber 610, first control the clamping member 223 and the locking assembly 224 to clamp the shock absorber 610; then control the driving member 2221 to drive the mounting seat 2222 to move toward the direction close to the clamping member 223, and then drive the first tightening gun 2223 to move toward the direction close to the clamping member 223 until the first tightening sleeve on the first tightening gun 2223 is sleeved on the fastening nut; finally, control the first tightening gun 2223 to operate, and the first tightening sleeve is driven by the first tightening gun 2223 to rotate, which can drive the fastening nut to rotate to tighten the fastening nut. After the fastening nut of the shock absorber 610 is tightened, the driver 2221 is first controlled to drive the mounting base 2222 away from the clamping member 223, thereby driving the first tightening gun 2223 away from the clamping member 223 until the first tightening sleeve is disengaged from the fastening nut. The clamping member 223 and the locking assembly 224 are then controlled to loosen the shock absorber 610. At this point, the shock absorber 610 can be transferred by the first transfer robot 230 to the brake disc 620 at the loading station 110. In one specific embodiment, the driver 2221 can be a driving cylinder or an oil cylinder, and the structure of the first tightening gun 2223 can refer to existing electric tightening guns.

[0057] In this embodiment, the mounting seat 2222 is slidably mounted on the mounting frame 221 by means of a slide rail and a slider.

In addition, a positioning plate 2231 is provided above the clamping member 223. The positioning plate 2231 has a positioning groove 2232 for accommodating the shock absorber 610. The positioning groove 2232 can pre-position the shock absorber 610 when the clamping member 223 clamps the shock absorber 610, thereby ensuring the accurate position of the shock absorber 610.

[0058] See also Figure 4 and Figure 5 In one embodiment of the present invention, the support mechanism 210 includes a frame 211, a conveying assembly 212, and a support assembly 213.

The support assembly 213 has a loading position, and the conveying assembly 212 can drive the support assembly 213 to the loading position. Specifically, the conveying assembly 212 is mounted on the frame 211 and can drive the support assembly 213 placed thereon to the loading position. The supporting 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 inserting the shock absorber 610, 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, which are arranged in a rectangular array on the support plate 2131. Each positioning block 2132 is provided with a positioning hole 2133. Each positioning hole 2133 has two first positioning surfaces arranged opposite to each other. The end of the shock absorber 610 inserted into the positioning hole 2133 has two second positioning surfaces arranged opposite to each other. The two first positioning surfaces mate with the two second positioning surfaces in a one-to-one correspondence. In addition, each positioning block 2132 is provided with two positioning rods 2134 spaced apart, with a clamping gap provided between the two positioning rods 2134. The cooperation between 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) allows the shock absorber 610 to 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 adjacent positioning rods 2134 of two adjacent positioning blocks 2132.

The first direction is Figure 4 The second direction is the direction indicated by X in Figure 4 The direction indicated by Z in . Specifically, the carrying assembly 213 can be moved along the first direction to the loading position under the drive of the first conveying unit 2121 and the second conveying unit 2122; and after the first transfer robot 230 has finished grabbing the shock absorber 610 on the carrying assembly 213, the driving cylinder 2111 can drive the second conveying unit 2122 to move along the second direction, thereby driving the carrying assembly 213 from the loading position to the recovery position, and then the second conveying unit 2122 can drive the carrying assembly 213 to move in the opposite direction of the first direction, so that the emptied carrying assembly 213 can be separated from the recovery position.

The push rod 312 can pass through the discharge port 322 and push the gasket and locking nut 611 at the discharge port 322 to the screw 621 of the brake disc 620. Specifically, the process of fitting the washer and locknut 611 onto the screw 621 of the brake disc 620 is as follows: first, the feeding mechanism 320 delivers the washer and locknut 611 to the discharge port 322 via the feeding pipe 321. Then, the push rod 312 of the pushing mechanism 310 rapidly moves toward the feeding station 120. During this process, the push rod 312 pushes the washer and locknut 611 at the discharge port 322 to directly above the screw 621 of the brake disc 620. Then, the push rod 312 rapidly moves away from the feeding station 120. At this time, due to inertia, the washer and locknut 611 do not return with the push rod 312, but remain directly above the screw 621. Finally, they fall downward under the action of their own gravity and fit onto the screw 621 of the brake disc 620. In one specific embodiment, the pushing mechanism 310 is arranged at an angle. One end of the push rod 312 that passes through the discharge port 322 is formed with 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 holes 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 a specific embodiment, there are four vibration plates, four feeding pipes 321, and four feeding mechanisms 320, and the vibration plates, the feeding pipes 321, and the feeding mechanisms 320 are arranged in a one-to-one correspondence. There are two feeding stations 120, and the four feeding mechanisms 320 are arranged in pairs above the two feeding stations 120. Two of the four vibration plates respectively deliver gaskets and locking nuts 611 to the two feeding mechanisms 320 above one of the feeding stations 120, and the other two of the four vibration plates respectively deliver gaskets and locking nuts 611 to the two feeding mechanisms 320 above the other feeding station 120. Specifically, during use, the corresponding program can be set so that the push rod 312 of the pushing mechanism 310 first delivers the gasket to the screw 621 of the brake disc 620, and then delivers the locking nut 611 to the screw 621 of the brake disc 620.

[0064] See also 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 feeding 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 separated from the feeding pipe 321, so that the feeding mechanism 320 can deliver the gasket and lock nut 611 to the discharge port 322, the blocking plate 333 can move under the action of the torsion spring 332 and close the discharge port 322 to prevent the gasket and lock nut 611 from falling out of the discharge port 322. When the push rod 312 of the pushing mechanism 310 moves toward the feeding station 120, the push rod 312 overcomes the force of the torsion spring 332 and pushes the blocking plate 333 to move and open the discharge port 322. At this time, the push rod 312 can push the gasket and lock nut 611 at the discharge port 322 to the screw 621 of the brake disc 620. In a specific embodiment, the blocking plate 333 is provided with a sliding groove 3331 for the push rod 312 to pass through.

Figure 7 The fourth direction is the direction indicated by M in Figure 7The direction indicated by N in the figure. Specifically, the first adjustment mechanism 340 can drive the pushing mechanism 310 to move in the third and fourth directions to ensure that when the push rod 312 is extended, 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 gasket 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 base body slidably arranged along the third direction, a first drive motor capable of driving the first base body to slide along the third direction, a second base body slidably arranged along the fourth direction, and a second drive motor capable of driving the second base body to slide along the fourth direction. The pushing mechanism 310 is disposed on the second base body.

The second transfer robot 410 can transfer the tightening member 430 and make the tightening member 430 is engaged with the first tightening head 422 or the second tightening head 424; when the tightening member 430 is engaged with the first tightening head 422, the second transfer robot 410 can transfer the tightening member 430 to the locking nut 611, and the tightening member 430 tightens the locking nut 611; when the tightening member 430 is engaged with the second tightening head 424, the second transfer robot 410 can transfer the tightening member 430 to the locking nut 631, and the tightening member 430 tightens the locking nut 631. In this embodiment, the second transfer robot 410 can transfer the tightening part 430 so that the tightening part 430 is engaged with the first tightening head 422 or the second tightening head 424 to replace the tightening head of the tightening part 430; at the same time, when the tightening part 430 is engaged with different tightening heads, the tightening part 430 can be transferred to different positions to tighten the locking nut 611 that fixes the shock absorber 610 or the locking nut 631 that fixes the swing arm 630. Specifically, when tightening the locking nut 611 that fixes the shock absorber 610, first control the second transfer robot 410 to transfer the tightening piece 430, and make the tightening piece 430 engage with the first tightening head 422, then control the second transfer robot 410 to transfer the tightening piece 430, and transfer the tightening piece 430 to the locking nut 611 of the tightening station 130 until the first tightening head 422 is sleeved on the locking nut 611, and finally control the tightening piece 430 to run, drive the first tightening head 422 to rotate, and then drive the locking nut 611 to rotate, tighten the locking nut 611, and fix the shock absorber 610 to the brake disc 62. 0; when tightening the locking nut 631 that fixes the swing arm 630, the second transfer robot 410 is first controlled to transfer the tightening member 430 and engage the tightening member 430 with the second tightening head 424. The second transfer robot 410 is then controlled to transfer the tightening member 430 to the locking nut 631 of the tightening station 130 until the second tightening head 424 is sleeved on the locking nut 631. Finally, the tightening member 430 is controlled to operate, driving the second tightening head 424 to rotate, thereby driving the locking nut 631 to rotate, tightening the locking nut 631, and fixing the swing arm 630 to the brake disc 620. In a specific embodiment, the tightening member 430 can be a tightening gun.

[0067] In this embodiment, both the first tightening head 422 and the second tightening head 424 are formed with an annular groove, and both the first and second clamping bases 421 and 423 are formed with semi-enclosed engaging portions that can be snapped into the corresponding annular grooves. The annular grooves and semi-enclosed engaging portions enable the tightening head and the clamping base to be snapped together, preventing the tightening head from vertically separating from the clamping base, thereby ensuring smooth engagement between the tightening head and the tightening gun. The first and second clamping bases 421 and 423 are both provided with detection sensors for detecting whether the tightening heads have been removed. Specifically, when the first tightening head 422 is removed, the detection sensor on the first clamping base 421 transmits the detection information to the external controller, which then controls the movement of the second transfer robot 410 based on the detection information, thereby transferring the tightening member 430 to the locking nut 611 of the tightening station 130 until the first tightening head 422 is sleeved on the locking nut 611. Finally, the tightening member 430 is controlled to operate, driving the first tightening head 422 to rotate, thereby driving 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 member 430 to the locking nut 631 and tightens the locking nut 631.

Specifically, the second limiting rod 442 is retractably mounted on the first limiting rod 441 and does not detach from the first limiting rod 441. The connection between the base 411 and the tightening member 430 by the first limiting rod 441 and the second limiting rod 442 can limit the range of motion of the tightening member 430.
