Description

Technical Field

[0001] This utility model relates to the field of electric tricycle brake shaft welding technology, specifically an auxiliary positioning device for welding electric tricycle brake shafts. Background Technology

[0002] Electric tricycles are three-wheeled transport vehicles that use batteries and electric motors for hauling goods or carrying passengers. They are commonly known as "three-wheeled vehicles" and can be classified into various types according to their purpose, such as household, freight, and factory types. According to their drive method, they can be classified into electric-assisted tricycles and pure electric tricycles. The brake axle of an electric tricycle is an important component of the braking system. Its main function is to transmit braking force to slow down or stop the vehicle.

[0003] A welding positioning device for axles, disclosed in CN220838662U, is provided with an axle positioning mechanism and a welding positioning mechanism on the through hole side of the fixed frame. This achieves radial positioning between the cylindrical welding base and the axle, avoiding the need to drill positioning cone holes on the axle and simplifying the process.

[0004] The axle welding positioning device can clamp and fix the axle through the positioning block. However, since the axle sizes are different, and the arc shape of the contact position between the positioning block and the axle cannot be adjusted, the positioning block is unstable when clamping axles of different sizes, which affects the welding effect. Therefore, it needs to be improved. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] This utility model provides the following technical solution:

[0026] Example 1

[0027] Please see Figure 1-4 This utility model provides a technical solution: an auxiliary positioning device for welding brake shafts of electric tricycles, including a support column 1, a processing table 2 fixedly connected to the top of the support column 1, a clamping mechanism 3 provided in the middle of the inner side of the processing table 2, and a welding mechanism 4 provided at the back end of the inner side of the processing table 2.

[0028] The clamping mechanism 3 includes a fixed plate 34, which is fixedly connected to the left and right sides of the bottom of the processing table 2. A first cylinder 33 is fixedly connected to the outside of the fixed plate 34. A moving plate 35 is fixedly connected to the inside of the first cylinder 33. A hollow plate 32 is fixedly connected to the top of the moving plate 35. A motor 31 is fixedly connected to the front of the hollow plate 32. A bidirectional threaded rod 38 is fixedly connected to the back of the motor 31. The bidirectional threaded rod 38 is rotatably connected to the inside of the hollow plate 32. A threaded plate 37 is threadedly connected to the outside of the bidirectional threaded rod 38. A support plate 39 is fixedly connected to the top of the threaded plate 37. A V-shaped clamping plate 36 is fixedly connected to the inside of the support plate 39.

[0029] Furthermore, a groove corresponding to the movement trajectory of the moving plate 35 is provided on the inner side of the processing table 2, and the moving plate 35 is slidably connected inside the groove. Through the groove, the moving plate 35 can slide on the inner side of the processing table 2. When the moving plate 35 moves, it can drive the hollow plate 32 to move.

[0030] Furthermore, a limiting groove corresponding to the movement trajectory of the threaded plate 37 is provided on the inner side of the hollow plate 32, and the threaded plate 37 is slidably connected inside the limiting groove. The limiting groove can limit the movement of the threaded plate 37, making the threaded plate 37 more stable during movement.

[0031] Furthermore, there are two V-shaped clamping plates 36, support plates 39, and threaded plates 37. The two threaded plates 37 are respectively threaded to the periphery of the bidirectional threaded rod 38, and the two V-shaped clamping plates 36 slide alternately. When the bidirectional threaded rod 38 rotates, it can drive the two threaded plates 37 to move simultaneously, so that the threaded plates 37 can drive the V-shaped clamping plates 36 to move through the support plate 39, so that the V-shaped clamping plates 36 can clamp and fix the brake axle of the electric tricycle.

[0032] Example 2

[0033] Please see Figure 1-4 Furthermore, based on Embodiment 1, the welding mechanism 4 further includes a third cylinder 48, which is fixedly connected to the right back end of the processing table 2. A slide plate 47 is fixedly connected to the left side of the third cylinder 48. A connecting frame 46 is fixedly connected to the top of the slide plate 47. A second cylinder 43 is fixedly connected to the top of the connecting frame 46. A lifting plate 45 is fixedly connected to the bottom of the second cylinder 43. A slide bar 44 is fixedly connected to the top of the lifting plate 45. A connecting plate 41 is fixedly connected to the bottom of the lifting plate 45. A welder 42 is fixedly connected to the inner side of the connecting plate 41.

[0034] Furthermore, the inner back end of the processing table 2 is provided with a guide groove corresponding to the movement trajectory of the slide plate 47, and the slide plate 47 is slidably connected inside the guide groove. The guide groove can limit the movement of the slide plate 47, making the slide plate 47 more stable during movement.

[0035] Furthermore, there are two slide bars 44, which are fixedly connected to the top left and right sides of the lifting plate 45 respectively, and are slidably connected to the inner side of the connecting frame 46 respectively. The slide bars 44 can limit the lifting plate 45, making the lifting plate 45 more stable during the lifting and moving process.

[0036] In actual operation, when this device is used, when welding the brake shaft of an electric tricycle is required, and the position of the V-shaped clamp 36 needs to be adjusted according to the length of the electric tricycle brake shaft, the first cylinder 33 is opened, causing the first cylinder 33 to push the moving plate 35 and the hollow plate 32 to move. The hollow plate 32 drives the support plate 39 and the V-shaped clamp 36 to move through the threaded plate 37, placing the electric tricycle brake shaft inside the V-shaped clamp 36. The motor 31 is then turned on, causing the motor 31 to drive the threaded plate 37 to move through the bidirectional threaded rod 38. The threaded plate 37 then drives the V-shaped clamp 36 to move through the support plate 39, allowing the V-shaped clamp 36 to clamp and fix the electric tricycle brake shaft.

[0037] Open the third cylinder 48, causing it to move the connecting frame 46 via the slide plate 47. The connecting frame 46 then moves the lifting plate 45 and the connecting plate 41 via the slide bar 44. This allows the connecting plate 41 to move the welder 42 to the appropriate position. Open the second cylinder 43, causing it to move the connecting plate 41 and the welder 42 to the appropriate height via the lifting plate 45. The welder 42 can then weld the electric tricycle brake shaft. When the welding position of the electric tricycle brake shaft needs to be adjusted, open the motor 31, causing it to rotate the bidirectional threaded rod 38 in the opposite direction. This causes the bidirectional threaded rod 38 to move the support plate 39 and the V-shaped clamp 36 via the threaded plate 37. This allows the V-shaped clamp 36 to release the electric tricycle brake shaft, enabling the operator to manually adjust the welding position of the electric tricycle brake shaft. This device can weld different positions of the electric tricycle brake shaft.
