Description

Technical Field

[0001] This utility model relates to the technical field of spot welding forestry engineering, specifically to a base plate structure for a spot welding X-axis module. Background Technology

[0002] The main function of the spot welding X-axis module is to control the precise movement of the welding electrode in the horizontal direction, thereby achieving precise positioning and control of the welding point. The X-axis module is driven by a motor and combined with transmission mechanisms such as ball screws, synchronous belts or linear guides to achieve precise movement of the base plate on the X-axis. As the requirements for welding workpieces increase, the structure of the X-axis module base plate also increases accordingly.

[0003] A general spot welding base plate for battery pack modules disclosed in the public account CN208879974U includes a spot welding base plate body, which includes a spot welding base plate, through holes, bolt holes, and a top block. Through holes are provided at the four corners of the spot welding base plate, and a number of evenly arranged bolt holes are provided on one side of the spot welding base plate. The top block is fastened to the surface of the spot welding base plate by a second bolt and the bolt holes.

[0004] The above document is simple and reasonable, with low cost. For battery pack modules of different shapes, there is no need to replace the spot welding base plate, which saves costs, simplifies the operation process, and improves the overall work efficiency.

[0005] The aforementioned document describes how to limit the workpiece by installing a top block on the threaded hole. However, due to the different shapes of the workpieces and the fixed position of the threaded hole, some parts are difficult to position during workpiece positioning, resulting in poor workpiece stability, affecting the spot welding effect, and making it inconvenient to adjust the spot welding angle of the workpiece above the base plate. Therefore, we propose a spot welding X-axis module base plate structure to solve the problems mentioned above. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0025] Please see Figure 1-6This utility model provides a technical solution: a base plate structure for a spot welding X-axis module, including a base 1, a base plate 3, and an electric telescopic rod 4. A universal rotating ball 2 is bonded to the upper center of the base 1, and the base plate 3 is positioned above the universal rotating ball 2. The lower center of the base plate 3 is concave, and the connection between the lower part of the base plate 3 and the universal rotating ball 2 is a rotatable connection, facilitating the rotation of the base plate 3 above the universal rotating ball 2 on the base 1 to adjust the spot welding angle of the workpiece. Electric telescopic rods 4 are rotatably connected to both ends of the base 1, and the output of the electric telescopic rods 4... The base plate 3 is connected to a sliding block 5 at one end, and the bottom two ends of the base plate 3 are provided with first sliding grooves 6. The electric telescopic rod 4 is set at an angle. There are two sets of electric telescopic rods 4 at both ends of the base 1. The two sets of electric telescopic rods 4 are symmetrically arranged about the central axis of the base 1. The output end of the sliding block 5 and the electric telescopic rod 4 are rotatably connected, and the sliding block 5 and the first sliding groove 6 below the base plate 3 form a snap-fit ​​sliding connection. The use of the two sets of inclined electric telescopic rods 4 can easily drive the sliding block 5 to slide on the first sliding groove 6 below the base plate 3, so as to easily adjust the use angle of the base plate 3.

[0026] Please see Figure 1-6 The upper surface of the base plate 3 is evenly provided with sliding cavities 7, and a connecting block 8 is provided inside the sliding cavity 7. A limit rod 9 is fixed above the connecting block 8. The four corners of the connecting block 8 are convex, and the connecting block 8 and the sliding cavity 7 on the surface of the base plate 3 form a snap-fit ​​sliding connection. The bottom of the connecting block 8 is connected to the bottom of the sliding cavity 7 on the surface of the base plate 3 through a spring 10, which facilitates the sliding of the connecting block 8 in the sliding cavity 7 on the surface of the base plate 3 for the placement of the workpiece. A second sliding groove 11 is provided in the middle of each of the four sides of the base plate 3, and a first bidirectional lead screw 12 is rotatably connected to the middle of one side of the base plate 3 in the lateral direction, and a second bidirectional lead screw 13 is rotatably connected to the middle of one side of the base plate 3 in the longitudinal direction. The first bidirectional lead screw 12 and Both ends of the surface of the second bidirectional lead screw 13 are equipped with pressing rods 14. The first bidirectional lead screw 12 is located above the second bidirectional lead screw 13, and the first bidirectional lead screw 12 and the second bidirectional lead screw 13 are vertically distributed. The first bidirectional lead screw 12 and the second bidirectional lead screw 13 are connected to the pressing rods 14 by threaded connection, and the pressing rods 14 are connected to the second slide groove 11 by snap-fit ​​sliding connection. The two sets of pressing rods 14 move in opposite directions on the first bidirectional lead screw 12 and the second bidirectional lead screw 13. They can move in opposite directions through the threaded movement of the first bidirectional lead screw 12 and the second bidirectional lead screw 13 with the pressing rods 14 on their surfaces, so that the two sets of pressing rods 14 move towards each other and press and fix the four corners of the workpiece.

[0027] Working principle: First, when using the machine, the base 1 is installed at the bottom of the X-axis module of the spot welding machine. Then, the workpiece to be spot welded is placed on the base plate 3. The base plate 3 is evenly provided with limit rods 9. When the workpiece is placed, the workpiece will squeeze the limit rods 9 so that the connecting block 8 below the limit rods 9 is compressed under the action of the spring 10. There are multiple sets of limit rods 9 evenly provided. The limit rods 9 can be compressed downward according to the shape of the workpiece. Then, by rotating the first bidirectional lead screw 12 and the second bidirectional lead screw 13, the first bidirectional lead screw 12 and the second bidirectional lead screw 13 are conveniently threaded with the extrusion rod 14 so that the extrusion rod 14 can slide on the second slide groove 11. This allows the extrusion rod 14 to extrude the four sides of the workpiece so as to fix the workpiece and improve the stability of the spot welding.

[0028] In use, the electric telescopic rod 4 on one side above the base 1 can be opened, so that the electric telescopic rod 4 drives the sliding block 5 to slide in the first sliding groove 6 below the base plate 3, thereby causing the base plate 3 to rotate on the universal rotating ball 2 above the base 1, which makes it easier to adjust the use angle of the base plate 3 and improve the use effect of the device. This is the working principle of the base plate structure of the spot welding X-axis module.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
