In this patent, two clamping components are used to weld the parts; however, the clamping range of the two clamping components is limited, making it difficult to clamp larger parts. Furthermore, in this patent, the drive rod is located inside the clamping components and is locked, preventing angle adjustment of the clamping components. Therefore, we present an electric vehicle parts welding equipment. Utility Model Content

[0004] The main objective of this invention is to provide a welding equipment for electric vehicle parts, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A welding equipment for electric vehicle parts includes a base, a clamping device fixedly connected to the upper right side of the base, a rodless cylinder fixedly connected to the upper left side of the base, a movable frame fixedly connected to the upper end of the rodless cylinder, a sliding groove opened at the upper end of the movable frame, a position adjustment device installed in the sliding groove, and the movable frame having an "L" shaped structure.

[0007] Preferably, the clamping device includes a connecting plate and a first motor. Connecting rods are fixedly connected to the left and right front ends of the connecting plate. A front clamping plate is fixedly connected to the front ends of the two connecting rods. A rear clamping plate is movably connected to the outer surfaces of the two connecting rods. Springs are sleeved on the outer surfaces of the two connecting rods. Clamping blocks are fixedly connected to the ends of the rear clamping plate and the front clamping plate that are close to each other. A top block is fixedly connected to the output end of the first motor. Slider blocks are fixedly connected to the lower ends of the front clamping plate and the rear clamping plate.

[0008] Preferably, both sliders have a narrow top and wide bottom structure, and both sliders are slidably connected to the upper end of the base.

[0009] Preferably, the No. 1 motor is fixed to the lower end of the base, and the output end of the No. 1 motor passes through the base.

[0010] Preferably, the front clamp, rear clamp, connecting plate, and two springs do not contact the base.

[0011] Preferably, the position adjustment device includes a mounting frame, which has an "L"-shaped structure. A round rod is movably connected to the left end of the mounting frame, and a threaded rod is threaded to the left end of the mounting frame. A second motor is fixedly connected to the right end of the threaded rod. An electric push rod is fixedly connected to the upper end of the mounting frame, and a welding head is fixedly connected to the output end of the electric push rod. The second motor is installed on the right end of the movable frame. The round rod is fixed in the slide groove, and the threaded rod is movably connected to the inner wall of the slide groove through a bearing.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, by setting a clamping device, the sliders at the lower ends of the front clamping plate and the rear clamping plate are slidably connected to the upper end of the base. By starting the No. 1 motor to drive the top block to rotate, the top block moves the connecting plate backward and the rear clamping plate forward. The connecting plate is connected to the front clamping plate through two connecting rods, which will cause the front clamping plate to move closer to the rear clamping plate. When the two are close, they will clamp the electric vehicle parts, which facilitates the welding of electric bicycle parts and improves the convenience and efficiency of clamping.

[0015] 2. In this utility model, by setting a position adjustment device on the movable frame, starting the No. 2 motor, the No. 2 motor drives the threaded rod to rotate, and the mounting bracket connected to the threaded rod moves left and right, causing the welding head to move left and right. Starting the electric push rod, the electric push rod pushes the welding head to move up and down. Since the movable frame is installed on the rodless cylinder, the rodless cylinder moves back and forth while also driving the welding head to move, so that the welding head can move in multiple directions, which facilitates the welding process of electric bicycle parts.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] A welding equipment for electric vehicle parts includes a base 1, a clamping device 2 fixedly connected to the upper right side of the base 1, a rodless cylinder 6 fixedly connected to the upper left side of the base 1, a movable frame 5 fixedly connected to the upper end of the rodless cylinder 6, a sliding groove 4 opened at the upper end of the movable frame 5, a position adjustment device 3 installed in the sliding groove 4, and the movable frame 5 has an "L" shaped structure.

[0026] In this embodiment, the clamping device 2 includes a connecting plate 21 and a first motor 28. Connecting rods 24 are fixedly connected to the left and right front ends of the connecting plate 21. A front clamping plate 22 is fixedly connected to the front ends of the two connecting rods 24. A rear clamping plate 26 is movably connected to the outer surfaces of the two connecting rods 24. Springs 23 are sleeved on the outer surfaces of the two connecting rods 24. Clamping blocks 25 are fixedly connected to the ends of the rear clamping plate 26 and the front clamping plate 22 that are close to each other. A top block 27 is fixedly connected to the output end of the first motor 28. Slider blocks 29 are fixedly connected to the lower ends of the front clamping plate 22 and the rear clamping plate 26. Both sliders 29 have a structure that is narrow at the top and wide at the bottom. Both sliders 29 are slidably connected to the upper end of the base 1. The first motor 28 is fixed to the lower end of the base 1, and the output end of the first motor 28 passes through the base 1. The front clamping plate 22, the rear clamping plate 26, the connecting plate 21, and the two springs 23 do not contact the base 1.

[0027] Through the above scheme: Motor 28 responds quickly, driving the top block 27 to rotate. The rotational motion of the top block 27 is converted into a thrust on the connecting plate 21, causing the connecting plate 21 to move smoothly backward. At the same time, due to the specific mechanical linkage between the rear clamping plate 26 and the top block 27, the rear clamping plate 26 will move forward accordingly. The connecting plate 21 is connected to the front clamping plate 22 through two sturdy and precisely calibrated connecting rods 24. This connection method ensures that the front clamping plate 22 can move synchronously with the movement of the connecting plate 21, that is, move closer to the rear clamping plate 26. As the distance between the front clamping plate 22 and the rear clamping plate 26 gradually decreases, they will tightly clamp the component located in the middle.

[0028] In this embodiment, the position adjustment device 3 includes a mounting frame 31, which has an "L" shaped structure. A round rod 32 is movably connected to the left end of the mounting frame 31, and a threaded rod 33 is threaded to the left end of the mounting frame 31. A second motor 36 is fixedly connected to the right end of the threaded rod 33. An electric push rod 34 is fixedly connected to the upper end of the mounting frame 31, and a welding head 35 is fixedly connected to the output end of the electric push rod 34. The second motor 36 is installed at the right end of the movable frame 5. The round rod 32 is fixed in the slide groove 4, and the threaded rod 33 is movably connected to the inner wall of the slide groove 4 through a bearing. Four threaded columns 61 are fixedly connected to the rodless cylinder 6. A connecting seat 51 is fixedly connected to the lower end of the movable frame 5. The connecting seat 51 is movably connected to the four threaded columns 61, and each of the four threaded columns 61 is threaded with a nut 62.

[0029] Through the above scheme: Motor 36 starts running and drives the threaded rod 33 to rotate. The mounting bracket 31 connected to the threaded rod 33 moves left and right along the axis of the threaded rod 33 under the drive of the thread. The welding head 35 is installed on the mounting bracket 31, so the welding head 35 also moves left and right, realizing flexible adjustment of the welding position in the horizontal direction. In order to further meet the precise control of the height of the welding head 35 during the welding process, the equipment is also equipped with an electric push rod 34. When it is necessary to adjust the height of the welding head 35, the electric push rod 34 is activated. The telescopic rod of the electric push rod 34 will push the welding head 35 up and down, thereby realizing precise adjustment of the welding height.

[0030] It should be noted that this utility model describes a welding device for electric vehicle parts. The front clamping plate 22 and the rear clamping plate 26 are key clamping components, each with a cleverly installed slider 29 at its lower end. These sliders 29 form a sliding connection with the carefully designed slide rail structure on the upper end of the base 1. This design not only ensures the smooth movement of the clamping plates but also greatly improves the flexibility and response speed of the clamping system. When electric bicycle parts need to be clamped for welding, the operator only needs to start the first motor 28. The first motor 28 responds quickly, driving the top block 27 to rotate. The rotational motion of the top block 27 is converted into a thrust on the connecting plate 21, causing the connecting plate 21 to move smoothly backward. Simultaneously, due to the specific mechanical linkage between the rear clamping plate 26 and the top block 27, the rear clamping plate 26 moves forward accordingly. The connecting plate 21 is connected to the front clamping plate 22 via two robust and precisely calibrated connecting rods 24. This connection method ensures that the front clamping plate 22 can move synchronously with the movement of the connecting plate 21, i.e., move closer to the rear clamping plate 26. As the distance between the front clamping plate 22 and the rear clamping plate 26 gradually decreases, they will tightly clamp the component located in the middle, providing stable and reliable support for subsequent welding operations of electric bicycle components. This significantly improves the convenience of clamping and work efficiency. After clamping the electric bicycle components, the next step... The welding process begins. At this point, motor 36 is started, driving the threaded rod 33 to rotate. The mounting bracket 31, threaded onto the threaded rod 33, moves left and right along the axis of the threaded rod 33 under the drive of the threads. The welding head 35 is mounted on the mounting bracket 31, and therefore moves left and right accordingly, allowing for flexible adjustment of the welding position in the horizontal direction. To further ensure precise control of the height of the welding head 35 during welding, the equipment is also equipped with an electric push rod 34. When the height of the welding head 35 needs to be adjusted, the electric push rod 34 is activated. The telescopic rod of the electric push rod 34 pushes the welding head 35 up and down, thus achieving butt welding. In addition to precise height adjustment, the movable frame 5 is securely mounted on the rodless cylinder 6. The rodless cylinder 6 has advantages such as compact structure, smooth operation, and fast response speed. It can move back and forth under the command of the control system. When the rodless cylinder 6 moves back and forth, it will drive the movable frame 5 and the welding head 35 mounted on the movable frame 5 to move synchronously. In this way, the welding head 35 can not only move in the horizontal and vertical directions, but also adjust in the back and forth direction, realizing flexible movement in multiple directions. This multi-directional movement design allows the welding head 35 to easily reach various welding parts of the electric bicycle components, greatly improving the flexibility and precision of welding.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
