[0002] As an important means of transportation, the manufacturing process of electric tricycles involves multiple steps, from design and planning to final commissioning and acceptance, each of which is crucial. This includes the production and processing of the tricycle's components.
[0003] In the manufacturing of electric tricycles, the welding fixture for the basket is an important piece of equipment. Traditional basket welding usually requires manual handling of the basket components and welding of the basket using the welding fixture. Manual operation has certain errors, which can cause the basket components to shake during welding, affecting the quality of the weld.
[0004] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. The existing welding fixture requires manual holding of the basket components and welding of the basket. Due to the certain errors in manual operation, the basket components shake during welding, affecting the welding efficiency; 2. The existing welding fixture has a relatively simple structure and insufficient height adjustment function. Due to the different heights of the operators, the use of the welding fixture is limited to a certain extent. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1 to 4This utility model provides a technical solution: a welding fixture for electric tricycle baskets with automatic positioning and clamping function, including a support base 1, one end of a hydraulic push rod 2 is installed in the middle of the top of the support base 1, the other end of the hydraulic push rod 2 is installed on a support platform 3, a first positioning slide rod 4 is installed on the inner wall of the support platform 3, a housing 5 is installed on the top surface of the support platform 3, a clamping component 6 is installed on the inner wall of the housing 5, a top cover 7 and an adjustment component 8 are installed on the top surface of the housing 5, and a vision sensor 9 is installed on the inner wall of the top cover 7.
[0024] The clamping assembly 6 includes a platform 601 installed on the inner wall of the housing 5. A bidirectional screw 602 is rotatably connected to the inner wall of the platform 601.

A second limiting plate 607 is installed at the other end of the first electric telescopic rod 606.
[0025] The adjustment assembly 8 includes a first limiting rail 801 and a second limiting rail 802 mounted on the top surface of the housing 5. A first one-way screw 803 is rotatably connected to the inner wall of the first limiting rail 801. A second motor 804 is mounted on one end of the first one-way screw 803. A third limiting rail 805 is mounted on one end of the outer wall of the first one-way screw 803. A second positioning slide rod 806 is mounted on the other end of the third limiting rail 805. A second one-way screw 807 is rotatably connected to the inner wall of the third limiting rail 805. A third motor 808 is mounted on one end of the second one-way screw 807.

A welding head 811 is mounted on the other end of the second electric telescopic rod 810.
[0026] In this embodiment, as Figure 1 As shown, the hydraulic push rod 2 and the support platform 3 constitute a lifting mechanism, and the support platform 3 and the first positioning slide rod 4 constitute a sliding mechanism. Through this design, the hydraulic push rod 2 can be activated to adjust the height of the support platform 3 according to the height of different users. The support platform 3 slides on the outer wall of the first positioning slide rod 4, which can effectively limit the movement of the support platform 3, so that the device has the function of height adjustment.
[0027] In this embodiment, as Figure 3As shown, there are two first limiting plates 605, and the first limiting plates 605 are symmetrical about the central axis of the platform 601. The first motor 603 forms a transmission mechanism with the first limiting plates 605 through the bidirectional screw 602 and the first slider 604. With this design, the basket body of the cart is placed on the surface of the platform 601. The basket body is monitored by the vision sensor 9, and the first motor 603 is controlled to drive the bidirectional screw 602 to rotate, so that the first sliders 604 move closer together.

The second limiting plate 607 effectively clamps the two sides of the outer wall of the annular connecting block, which facilitates the welding of the basket and the annular connecting block.
[0029] In this embodiment, as Figure 4 As shown, the second motor 804 forms a transmission mechanism with the first one-way screw 803 and the third limiting rail 805. With this design, the second motor 804 can be started by monitoring the vision sensor 9. The second motor 804 drives the first one-way screw 803 to rotate and controls the movement of the third limiting rail 805, thereby adjusting the longitudinal position of the welding head 811 to facilitate welding of the basket.
[0030] In this embodiment, as Figure 4 As shown, the third motor 808 forms a transmission mechanism with the second one-way screw 807 and the second slider 809. With this design, the third motor 808 can be started by monitoring the vision sensor 9, which drives the second one-way screw 807 to rotate and controls the movement of the second slider 809. This allows the lateral position of the welding head 811 to be adjusted, making it easier to weld the basket.
[0031] In this embodiment, as Figure 4 As shown, the second electric telescopic rod 810 and the welding head 811 constitute a telescopic mechanism; through this design, the distance between the welding head 811 and the welding point can be monitored in real time by the vision sensor 9, and the height of the welding head 811 can be adjusted by the second electric telescopic rod 810, which facilitates the welding of the basket.
[0032] The usage and advantages of this utility model: The welding fixture for electric tricycle baskets with automatic positioning and clamping function works as follows:
[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, firstly, the hydraulic push rod 2 is activated to adjust the height of the support platform 3 according to the height of different users. The support platform 3 slides on the outer wall of the first positioning slide rod 4 to adjust the support platform 3 to a suitable height. Then, the basket body is placed on the surface of the storage platform 601. The basket body is monitored by the vision sensor 9, and the first motor 603 is controlled to drive the bidirectional screw 602 to rotate, so that the first sliders 604 come together. The first limiting plate 605 effectively clamps the two sides of the outer wall of the basket body. Then, the annular connecting block is attached to the outer wall of the basket body, and the first electric telescopic rod 606 is activated to extend the second limiting plate 607. Plate 607 effectively clamps the outer walls of the annular connecting block on both sides. Then, through the monitoring of vision sensor 9, the second motor 804 is started. The second motor 804 drives the first one-way screw 803 to rotate, controlling the movement of the third limit rail 805, thereby adjusting the longitudinal position of the welding head 811. The third motor 808 can also be started to drive the second one-way screw 807 to rotate, controlling the movement of the second slider 809, thereby adjusting the lateral position of the welding head 811. The height of the welding head 811 is adjusted by the second electric telescopic rod 810. The basket and the annular connecting block can then be welded using the welding head 811.
