[0054] In some embodiments, a tool hanging box 17 is mounted on the support column 11 to facilitate the storage and placement of assembly tools, which is beneficial for finding and taking tools and avoiding disordered placement or even loss of tools. In the exemplary embodiment, an operation procedure 19 is arranged on both sides of the frame 20 of the linear conveying mechanism 2 corresponding to each station, which is convenient for the operator to watch the process procedure and does not need to additionally set up a support to place the operation procedure; at the same time, placing the operation procedure 19 on the overhead frame 20 can avoid accidental contamination of the operation procedure 19.

[0056] In some embodiments, a code scanning gun 8 is placed on the support frame 1 at the exit of the linear conveying mechanism 2, and each assembled bicycle can be automatically recorded and calculated by the code scanning gun 8, thereby realizing automatic statistics of production data.

[0057] Please refer to Figure 11 , Figure 12In some embodiments, the cantilever clamp 3 comprises a straight arm 31, a rotating base 32 mounted on the straight arm 31 and rotatable relative to the straight arm 31 in a horizontal plane, a rotating arm 33 mounted on the rotating base 32 and rotatable relative to the rotating base 32 in a vertical plane, and a clamping unit 34 mounted on the rotating arm 33. The straight arm 31 has a connecting head 311 at one end, and the connecting head 311 is fixedly connected with the chain plate 28. The rotating base 32 is mounted at the other end of the straight arm 31.

[0058] The rotating base 32 is provided with a first locking mechanism 35. The first locking mechanism 35 can lock the rotating base 32 and prevent it from rotating relative to the straight arm 31 in the horizontal plane. Please refer to Figure 13 、 Figure 14 In exemplary embodiments, the first locking mechanism 35 comprises a gear sleeve 351, a locking tooth block 352, and a first operating mechanism. The locking tooth block 352 is used to engage with the gear sleeve 351. The axis of the gear sleeve 351 is parallel to the axial direction of the straight arm 31. The gear sleeve 351 is fixedly connected with the straight arm 31. The locking tooth block 352 is mounted in a straight slot of the rotating base 32 and is linearly movable relative to the gear sleeve 351. The locking tooth block 352 has a locking position and an unlocking position. When the locking tooth block 352 is in the locking position, the locking tooth block 352 engages with the gear sleeve 351. When the locking tooth block 352 is in the unlocking position, the locking tooth block 352 is separated from the gear sleeve 351. The first operating mechanism is used to drive the locking tooth block 352 to move linearly relative to the gear sleeve 351, so as to switch the gear sleeve 351 between the locking position and the unlocking position.

[0059] In some embodiments, the upper end of the gear sleeve 351 is fixedly connected with the lower end of the straight arm 31 by screws or bolts.

[0060] It is worth noting that there are many mechanisms for driving the locking tooth block 352 to move linearly, such as gear and rack, screw and nut, cam mechanism, etc. Those skilled in the art can reasonably set them according to the needs. In exemplary embodiments, as shown in Figure 14As shown, the first operating mechanism includes a locking knob 353, the rotating base 32 is sleeved outside the gear sleeve 351 and is rotationally connected with the gear sleeve 351, the locking tooth block 352 is arranged in the linear groove of the rotating base 32, and the locking tooth block 352 can only move radially relative to the rotating base 32 under the constraint of the linear groove. The rotating base 32 has a threaded hole matched with the locking knob 353, one end of the locking knob 353 is arranged in the threaded hole and is rotationally connected with the locking tooth block 352. The clockwise or counterclockwise locking knob 353 can move the locking knob 353 radially inward or outward relative to the rotating base 32, and in turn drive the locking tooth block 352 to move radially inward or outward, so that the locking tooth block 352 is engaged with or separated from the gear sleeve 351, when the locking tooth block 352 is engaged with the gear sleeve 351, the locking tooth block 352 and the rotating base 32 cannot rotate relative to the gear sleeve 351 and the straight arm 31 in the horizontal plane, to realize locking; and when the locking tooth block 352 is separated from the gear sleeve 351, the locking tooth block 352 and the rotating base 32 can rotate relative to the gear sleeve 351 and the straight arm 31 in the horizontal plane, to realize unlocking.

[0061] Please refer to Figure 13 、 Figure 14 In the exemplary embodiment, the rotating base 32 includes a tray 321, a gland 322 and a rotating shaft 323, the rotating shaft 323 is coaxial with the gear sleeve 351, the upper part of the rotating shaft 323 is arranged in the gear sleeve 351 and is rotationally matched with the gear sleeve 351 through a bearing, and the tray 321 is fixedly connected with the flange at the lower end of the rotating shaft 323 through a screw; the gland 322 is arranged above the tray 321 and is fixedly connected with the tray 321, the locking tooth block 352 is arranged in the linear groove of the gland 322, and the locking knob 353 is arranged in the threaded hole of the gland 322. The tray 321 and the gland 322 are rotationally matched with the gear sleeve 351 through bearings.

[0062] The rotating arm 33 is configured with a second rotating locking mechanism 36, through which the rotating angle of the rotating arm 33 in the vertical plane can be controlled. Please refer to Figure 13 、 Figures 15 to 17In the example embodiment, the second rotation locking mechanism 36 comprises a brake disc 361 fixedly connected with the tray 321, a rotating shaft 360 fixedly installed in the center hole of the brake disc 361, and a locking pin assembly installed on the brake disc 361. The rotating arm 33 is rotationally connected with the rotating shaft 360 and is provided with a bearing therebetween. The locking pin assembly comprises a locking pin 362, a locking pin seat 363, and an operating handle 364. The locking pin seat 363 and the brake disc 361 are each provided with a pin hole matched with the locking pin 362. The locking pin 362 is installed in the pin holes of the brake disc 361 and the locking pin seat 363 and is movable relative to the brake disc 361 in a first direction parallel to the axial direction of the rotating shaft 360. A plurality of locking holes 331 are arranged on the rotating arm 33 at the same circumference around the rotating shaft 360. The rotating arm 33 is rotatable to make the plurality of locking holes 331 successively face the locking pin 362. The locking pin 362 has a locking position and an unlocking position. When the locking pin 362 is at the locking position, the locking pin 362 is inserted into one of the locking holes 331 of the rotating arm 33. When the locking pin 362 is at the unlocking position, the locking pin 362 is separated from the rotating arm 33. The operating handle 364 is connected with the locking pin 362 and is used to drive the locking pin 362 to move relative to the brake disc 361 in the first direction, thereby switching the locking pin 362 between the locking position and the unlocking position.

[0063] When the locking pin 362 is at the locking position, the locking pin 362 is prevented from moving to the unlocking position under unexpected circumstances. Please refer to Figure 15 、 Figure 17 In the example embodiment, the locking pin seat 363 is provided with a slot hole 365 matched with the operating handle 364. One end of the operating handle 364 extends into the locking pin seat 363 from the slot hole 365 and is connected with the locking pin 362. The slot hole 365 allows the operating handle 364 to move relative to the locking pin seat 363 in the first direction and limits the linear displacement of the locking pin 362. One end of the slot hole 365 is provided with a clamping hole 366. When the locking pin 362 is driven by the operating handle 364 to move to the locking position, the operating handle 364 is located at the clamping hole 366. At this time, rotating the operating handle 364 around the locking pin 362 can clamp the handle rod into the clamping hole 366. Since the clamping hole 366 limits the operating handle 364, the locking pin 362 is prevented from exiting from the locking hole 331 of the rotating arm 33, thereby keeping the rotating arm 33 in the locked state.

[0064] It is worth mentioning that the locking pin seat 363 and the brake disc 361 can be integrally manufactured or separately manufactured.

[0065] When the locking pin 362 is switched to the unlocking position to facilitate the adjustment of the angle of the rotating arm 33, the rotating arm 33 is prevented from rotating by itself under the action of its own weight and the gravity of the bicycle, thereby increasing the stability of the angle adjustment. Please refer to Figure 13 、 Figure 17In some embodiments, a damping device is installed on the brake disc 361, which includes at least one round head spring pin 37 installed in a mounting cavity of the brake disc 361, and a plurality of index grooves 332 are arranged on the rotating arm 33 around the rotating shaft 360 on the same circumference and matched with the round head spring pin 37, the free end of the round head spring pin 37 can be inserted into one of the index grooves 332 under the action of its own spring, thereby preventing the rotating arm 33 from rotating in the vertical plane; but when the rotating external force increases to a certain extent, the round head spring pin 37 can be retracted, thereby rotating the rotating arm 33 in the vertical plane. As a preferred, the round head spring pin 37 is provided with a spring force adjusting nut 371, the round head spring pin 37 and the corresponding spring force adjusting nut 371 are installed in the same mounting cavity, the round head spring pin 37 includes a ball head pin and a spring, the spring force adjusting nut 371 is threadedly matched with the brake disc 361, the ball head pin is gap matched with the mounting cavity, and the two ends of the spring act on the ball head and the spring force adjusting nut 371 respectively. Under the action of the spring, the free end of the ball head pin protrudes from the brake disc 361. Through the spring force adjusting nut 371, on the one hand, the round head spring pin 37 can be limited, and on the other hand, the spring force of the round head spring pin 37 can be adjusted.

[0066] Of course, the edges of the index grooves 332 are smoothly transitioned so as to facilitate the free end of the round head spring pin 37 to slide into or out of the index grooves 332.

[0067] It is worth noting that the number of index grooves 332 can be reasonably set according to the need. In some embodiments, the number of index grooves 332 is equal to and corresponds to the number of lock holes 331, when the round head spring pin 37 is clamped into a certain index groove 332, the locking pin 362 is just opposite to one of the lock holes 331. When it is necessary to adjust the angle of the rotating arm 33 in the vertical plane, the locking pin 362 is moved backward away from the rotating arm 33 by operating the handle 364, and then the rotating arm 33 is slightly rotated by applying a rotating force, with the rotation of the rotating arm 33, the round head spring pin 37 will be clamped into the index grooves 332 one by one, so that the operator will have a jamming feeling when rotating. Therefore, whether the locking pin 362 is opposite to one of the lock holes 331 can be judged by the jamming feeling of the round head spring pin 37 and the index grooves 332; when the rotating arm 33 is rotated to the appropriate angle, the locking pin 362 is moved forward to be inserted into the corresponding lock hole 331 of the rotating arm 33 by operating the handle 364, so as to fix the angle of the rotating arm 33 in the vertical plane. As Figure 16 As shown in the figure, in the exemplary embodiment, a corresponding lock hole 331 is formed in the bottom opening of each index groove 332.

[0068] It is worth noting that the number of round head spring pins 37 can be reasonably set according to the need; as a preferred, the round head spring pin 37 has at least two. In the exemplary embodiment, the round head spring pin 37 has three.

[0069] The clamping unit 34 can be an inner expanding clamping tool or an outer clamping tool. In the exemplary embodiment, the clamping unit 34 is an inner expanding clamping tool. The inner expanding clamping tool can have various structures, which can be selected by those skilled in the art as needed.

[0070] Please refer to Figure 13 In the exemplary embodiment, the clamping unit 34 includes a mounting seat 340, an expanding body for being inserted into a pipe of a bicycle frame and being fixedly expanded therein, and an expanding trigger mechanism for driving the expanding body to switch between an expanding state and a loosening state. The mounting seat 340 is mounted on the connecting side wall 38, which is fixedly connected with the rotating arm 33 by bolts. The bolt connection is detachable, so as to facilitate replacement of different types of clamping units 34 and adaptation to assembly of different types of bicycles.

[0071] The expanding body includes a taper sleeve 341 and at least two expanding blocks 342. The taper sleeve 341 has a straight cylinder segment and a taper segment. The upper end of the straight cylinder segment is connected with the mounting seat 340, and the lower end of the straight cylinder segment is connected with the upper segment of the taper segment. The inner surface of the expanding block 342 is an inner taper surface matched with the outer taper surface of the taper segment. The expanding blocks 342 are arranged on the outer side of the taper sleeve 341 in the circumferential direction and are in contact with the outer taper surface of the taper sleeve 341.

[0072] The expanding trigger mechanism includes a screw rod 343, an adjusting nut 344, and a second operating mechanism. The adjusting nut 344 is built in the taper sleeve 341 coaxially with the taper sleeve 341.

The expanding blocks 342 have clamping grooves matched with the clamping blocks 345. The taper sleeve 341 has avoiding openings 3411 for the clamping blocks 345 to pass through. The clamping blocks 345 pass through the avoiding openings 3411 of the taper sleeve 341 and are installed in the clamping grooves of the expanding blocks 342, so as to realize the movable connection between the expanding blocks 342 and the adjusting nut 344. The screw rod 343 can drive the adjusting nut 344 to move axially in the taper sleeve 341. The adjusting nut 344 can drive the expanding blocks 342 to move synchronously axially through the clamping blocks 345. Meanwhile, the expanding blocks 342 can also move radially along the outer taper surface of the taper sleeve 341, so as to realize the switching of the expanding blocks 342 between the positions of approaching each other and moving away from each other.

[0074] In some embodiments, the adjusting nut 344 and the clamping blocks 345 are integrally manufactured.
