[0002] When manufacturing the brake boxes for shared bicycles, it is necessary to assemble the various components that make up the brake box. This requires the use of an assembly machine. During assembly, a robotic arm is typically used to pick up the corresponding parts and complete the assembly operation.

[0003] The gate boxes are connected to each other by bolts during assembly. The large number of bolts makes disassembly time-consuming and laborious. In addition, the cable of the electric tightening shaft in the assembly machine occupies a lot of space and is difficult to arrange. The installation of the tightening shaft is also difficult, which greatly increases the difficulty and cost of equipment manufacturing.

[0004] Therefore, it is necessary to invent a multi-station linkage automated assembly machine for shared bicycle brake boxes to solve the above problems. Utility Model Content

The screw shaft is telescopically slidably connected to the bottom end of the drive shaft. A return spring is sleeved on the outer wall of the screw shaft, and the working height of the screw shaft can be adjusted by the return spring.

[0008] Preferably, a lifting cylinder is fixedly connected to the top of the assembly frame, and the output end of the lifting cylinder is fixedly connected to the top of the lifting seat. Activating the lifting cylinder drives the lifting seat to rise and fall.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figure 1-5The diagram shows a multi-station linkage automated assembly machine for shared bicycle brake boxes, comprising an assembly platform 1. A multi-station bolt tightening mechanism 2 is provided on the surface of the assembly platform 1. The multi-station bolt tightening mechanism 2 includes an assembly frame 201 fixedly connected to the top of the assembly platform 1. A lifting seat 202 is provided below the assembly frame 201. A sealing box 203 is fixedly connected to the bottom end of the lifting seat 202. A starter motor 204 is fixedly connected to the top end of the lifting seat 202. An outer sprocket 208 is fixedly connected to the bottom end of the starter motor 204. A chain 205 is provided on the outer side of the outer sprocket 208, and the chain 205 is located at... Inside the sealed box 203, several sets of external chain teeth 206 are fixedly connected to the outer wall of the chain 205, and the external chain teeth 206 mesh with the external sprockets 208. Several sets of internal chain teeth 207 are fixedly connected to the inner wall of the chain 205, and four sets of internal sprockets 212 mesh with the inner wall of the internal chain teeth 207. A turning shaft 211 is provided below the internal sprockets 212. By starting the motor 204 and cooperating with the external chain teeth 206, the chain 205 is driven to move, thereby cooperating with other parts to achieve the tightening of bolts by multiple sets of turning shafts 211. A drive shaft 209 is fixedly connected to the bottom end of the internal sprockets 212. 09 is rotatably connected to the inner side of the sealing box 203. The rotating shaft 211 is telescopically slidably connected to the bottom end of the transmission shaft 209. A return spring 210 is sleeved on the outer wall of the rotating shaft 211. The working height of the rotating shaft 211 can be adjusted by the return spring 210. The top of the assembly frame 201 is fixedly connected to the lifting cylinder 5. The output end of the lifting cylinder 5 is fixedly connected to the top of the lifting seat 202. When the lifting cylinder 5 is activated, the lifting seat 202 is lifted and lowered. Through the cooperation of the assembly table 1 and the multi-station bolt tightening mechanism 2, after the gate box is initially assembled by the pressing mechanism 4, it is transported to the assembly stage by the conveying mechanism 3. Below the mounting bracket 201, the lifting cylinder 5 is activated to lower the lifting seat 202 and the sealing box 203, which in turn lowers the drive shaft 209 and the tightening shaft 211. The tightening shaft 211 and the return spring 210 work together to accommodate bolts at different heights and installation positions. The starting motor 204 is controlled to drive the outer sprocket 208 to rotate. The outer sprocket 208 drives the outer chain teeth 206 and the chain 205 to rotate. In turn, the chain 205 and the inner chain teeth 207 drive the inner sprocket 212 and the drive shaft 209 to rotate. Finally, the drive shaft 209 drives the tightening shaft 211 to rotate, thus tightening the bolts.

[0025] Refer to the instruction manual appendix Figure 1-5An oil lubricating tank 6 is fixedly connected inside the assembly frame 201, and an oil injection valve is fixedly connected to the back side of the assembly frame 201. Two sets of drainage hoses 7 are fixedly connected to the bottom end of the oil lubricating tank 6, and the drainage hoses 7 communicate with the sealing box 203. Oil is injected into the oil lubricating tank 6 through the assembly frame 201. Two sets of external nozzles 8 are fixedly connected to the inner wall of the sealing box 203. The external nozzles 8 are located outside the outer chain teeth 206, and lubricate the outer chain teeth 206 and the outer sprocket 208 through the external nozzles 8. An inner nozzle 9 is fixedly connected to the bottom wall of the sealing box 203. The inner nozzle 9 is located inside the inner chain tooth 207. The inner sprocket 212 and the inner chain tooth 207 are lubricated by the inner nozzle 9. A conveying mechanism 3 is installed on the surface of the assembly table 1. A pressing mechanism 4 is fixedly connected to the top of the assembly table 1 and is located in front of the multi-station bolt tightening mechanism 2. The pressing mechanism 4 and the conveying mechanism 3 cooperate with the multi-station bolt tightening mechanism 2 to achieve the compaction and other processes to improve the linkage of the structure.

[0026] The working principle of this practical application is as follows:

[0027] Refer to the instruction manual appendix Figure 1-5 When the gate box needs to be assembled, the gate box parts are placed on the surface of the conveying mechanism 3, and then the gate box is pressed by the pressing mechanism 4 for preliminary assembly. After the preliminary assembly is completed, bolts are inserted into the bolt holes on the surface of the gate box. The gate box is then sent to the bottom of the assembly frame 201 by the conveying mechanism 3. The lifting cylinder 5 is activated to drive the lifting seat 202 and the sealing box 203 to descend, which in turn drives the transmission shaft 209 and the turning shaft 211 to descend. The turning shaft 211 and the return spring 210 cooperate to accommodate bolts of different heights and installation positions. After the screwing shaft 211 contacts the bolt, the starter motor 204 is controlled to drive the outer sprocket 208 to rotate. The outer sprocket 208 drives the outer chain teeth 206 and the chain 205 to rotate, which in turn drives the inner sprocket 212 and the drive shaft 209 to rotate through the chain 205 and the inner chain teeth 207. In turn, the drive shaft 209 drives the screwing shaft 211 to rotate, thereby tightening the bolt. This achieves multi-station automatic assembly. When the chain 205 rotates, the outer nozzle 8 and the inner nozzle 9 are activated to lubricate both the inner and outer sides of the chain 205 to extend its service life.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
