Description

Technical Field

[0001] This utility model relates to the technical field of electric bicycle assembly equipment, and more specifically, to an adjustable electric bicycle assembly and fixing device. Background Technology

[0002] Electric bicycles, as an environmentally friendly and convenient means of transportation, are increasingly widely used in modern society. With the continuous expansion of the electric bicycle market, the requirements for the production efficiency and quality of electric bicycles are also getting higher and higher. In the production process of electric bicycles, the assembly process is a crucial link, which is directly related to the performance and quality of electric bicycles.

[0003] In the traditional electric bicycle assembly process, the use of fixing devices is essential. However, existing electric bicycle assembly fixing devices have many shortcomings and are difficult to meet current production needs. On the one hand, traditional fixing devices are often structurally fixed and lack adjustability, making them unable to adapt to the fixing requirements of electric bicycle frames of different sizes and types. This leads to workers needing to frequently change fixing devices or adjust the position of the frame during assembly, greatly reducing assembly efficiency.

[0004] On the other hand, traditional fixing devices often fail to guarantee the stability and accuracy of electric bicycle frames. Due to the diverse materials and structures of electric bicycle frames, traditional fixing devices may experience slippage or misalignment during the fixing process, leading to safety hazards or performance issues in the assembled electric bicycle. Therefore, we propose an adjustable electric bicycle assembly fixing device. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 This utility model provides a technical solution: an adjustable electric bicycle assembly and fixing device, including a support frame 1, a fixing clamping assembly 2 on the top plate of the support frame 1, the fixing clamping assembly 2 including two symmetrical first cylinders 20 fixedly installed on the top plate of the support frame 1, a crossbeam 21 is provided at the end of the telescopic shaft of the two first cylinders 20, the extension and retraction of the telescopic shaft of the first cylinders 20 are used to adjust the height of the crossbeam 21; a support plate 22 is fixedly installed on the front side of the crossbeam 21, a second cylinder 23 is fixedly installed on the top surface of the crossbeam 21, a rectangular sleeve 24 is provided on the telescopic shaft of the second cylinder 23, the rectangular sleeve 24 is sleeved on the crossbeam 21 and slidably connected to the crossbeam 21, a horizontal plate 25 is fixedly installed on the front side of the rectangular sleeve 24, and a third cylinder 26 is fixedly installed on the top surface of both the support plate 22 and the horizontal plate 25, so that the distance between the two third cylinders 26 can be adjusted, which is beneficial for subsequent clamping operations of corresponding parts;

[0027] Specifically, a clamping plate 262 is provided at the end of the telescopic shaft of the third cylinder 26, which is used for clamping operations; a lifting plate 27 is fixedly installed on the bottom surface of the crossbeam 21, and multiple detachable lifting rods 282 are provided on the lifting plate 27, which are used for supporting the frame.

[0028] In this embodiment, a fixed base plate 10 is fixedly installed at the bottom of the left and right side plates of the support frame 1. The fixed base plate 10 is fixedly installed on the external base, so that the entire device can be stably fixed on the external base, ensuring that the device will not shake or shift during the assembly of the electric bicycle, and providing a stable operating platform for the assembly work.

[0029] Specifically, a steel plate 201 is fixedly installed at the end of the telescopic shaft of the first cylinder 20, and a crossbeam 21 is fixedly installed on the bottom surface of the two steel plates 201 by multiple fastening bolts; a fixed seat 231 is fixedly installed at the end of the telescopic shaft of the second cylinder 23, and a rectangular sleeve 24 is fixedly installed on the bottom surface of the fixed seat 231 by multiple fastening bolts; a bolt plate 261 is fixedly installed at the end of the telescopic shaft of the third cylinder 26, and a clamping plate 262 is fixedly installed on the bottom surface of the bolt plate 261 by multiple fastening bolts, which facilitates the fixed installation operation.

[0030] Furthermore, an anti-slip pad 263 is provided on the bottom surface of the clamping plate 262.

The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0034] When using the adjustable electric bicycle assembly and fixing device of this utility model, the operator first ensures that the position of the left lifting rod 282 remains unchanged according to the shape and size of the frame. Then, the position of the right lifting rod 282 is adjusted, and the stud 28 is tightened into the threaded cylinder 271. At this time, the frame is then suspended on multiple lifting rods 282. Next, the second cylinder 23 is activated and put into operation. The operation of the second cylinder 23 adjusts the position of the right clamping plate 262. Then, the third cylinder 26 is activated and put into operation. The telescopic shaft of the third cylinder 26 extends, causing the clamping plate 262 to clamp and fix the frame on the corresponding lifting rod 282. Then, the first cylinder 20 is activated and put into operation. The operation of the first cylinder 20 extends or shortens its telescopic shaft, which can adjust the height of the frame. Finally, other accessories are installed on the frame to complete the assembly and fixing operation.
