Abstract

Technical Field
[0001] The utility model belongs to the technical field of welding positioning, and particularly relates to a positioning device for a top cover pressing plate. Background Art
[0002] To ensure the consistency of the horizontal position and vertical height of the product to be welded, the existing positioning device usually requires the top cover pressing plate to cooperate with the side positioning structure and the bottom plate structure. The bottom plate is a rebound structure designed with springs. When positioning the product, the battery will move down as the top cover pressing plate is pressed down, avoiding damage to the product. Then, the battery is fixed and positioned through the side positioning structure. With the fatigue of the bottom plate spring, the relative vertical height of the product will change, which will greatly affect the quality of the product.
[0003] At the same time, if the friction provided by the side positioning is less than the elastic force of the bottom plate spring, the relative vertical height of the product will also change. Increasing the pressure of the side positioning may cause the product to deform, increasing the debugging difficulty and debugging cost of the equipment. Summary of the Utility Model

At the same time, the pressing block 6 is limited in the installation hole 11 and can slide in the installation hole 11, but is limited by the installation hole 11 for sliding and cannot slide out of the installation hole 11. By providing the pressing block 6, the battery can be pressed down onto the bottom cover through the top cover 1, so that the battery is clamped between the top cover 1 and the bottom cover, and the welding process on the top of the battery can be realized. In addition, the top cover 1 can be used to connect with a numerical control device to realize the precise pressing of the top cover 1 on the battery.
[0025] Please refer to Figures 4-5 As shown, a limiting column 10 is formed at one end of the positioning nut 5. The spring 8 is sleeved on the limiting column 10, and one end of it abuts against one end of the positioning nut 5. The limiting column 10 is used for the connection between the spring 8 and the positioning nut 5, so that the spring 8 is sleeved on the limiting column 10. At the same time, the other end of the spring 8 abuts against one end of the positioning nut 5, realizing the connection between the spring 8 and the positioning nut 5, and providing a reset for the movement of the pressing block 6 in the installation hole 11.
[0026] Please refer to Figures 4-5As shown, a groove 9 is formed at one end of the pressing block 6 close to the spring 8, and one end of the spring 8 away from the positioning nut 5 abuts against the groove 9. The groove 9 is used for the connection between the spring 8 and the pressing block 6, providing an installation space for the connection of the spring 8, enabling one end of the spring 8 to abut in the groove 9, realizing the connection and limit of the groove 9. At the same time, the pressing block 6 is adapted to the mounting hole 11, enabling the pressing block 6 to move back and forth in the mounting hole 11. When the spring 8 is compressed, the battery is clamped. After the top cover 1 is lifted by the numerical control equipment, the spring 8 resets, and at the same time, the pressing block 6 resets.
[0027] Please refer to Figures 4-5 As shown, a spring inner cavity 7 for the movement of the pressing block 6 is formed between one end of the mounting hole 11 and the positioning nut 5, enabling the pressing block 6 to move in the spring inner cavity 7. A limiting ring 12 is provided on the mounting hole 11, and the limiting ring 12 is fixedly connected to the inner wall of the mounting hole 11. The limiting ring 12 is used to limit the maximum stroke of the pressing block 6 moving in the spring inner cavity 7, preventing the pressing block 6 from sliding out of the spring inner cavity 7, and realizing the sliding limit of the pressing block 6 in the spring inner cavity 7.
[0028] Please refer to Figures 1-2 As shown, there are multiple mounting holes 11, and the positioning nut 5, the positioning nut 5 and the pressing block 6 are all arranged in the multiple mounting holes 11. The multiple positioning nuts 5 are located outside the hollow part 2 and are distributed along the contour path of the hollow part 2, realizing the uniform pressing of different areas of the battery, and pressing the battery on the bottom plate or the workpiece to be welded.
[0029] Please refer to Figures 1-2 As shown, multiple bolt fixing holes 3 are provided on the top cover 1, and the multiple bolt fixing holes 3 are evenly distributed on the top cover 1. The fixing holes are used for the installation connection with the electric control equipment, enabling the top cover 1 to be connected to the automation equipment. By installing the equipment with bolts and the bolt fixing holes 3, the connection of the top cover 1 is realized, and further the precise control of the downward pressure of the top cover 1 is realized.
[0030] Please refer to Figure 1 As shown, the fixing holes are counterbored holes, which are convenient for the installation connection between the top cover 1 and the automation equipment.
[0031] Please refer to Figures 1-2 As shown, positioning pin holes 4 are provided on the top cover 1, and the positioning holes penetrate through the top cover 1. The positioning pin holes 4 are used for positioning during the installation connection with the equipment on the one hand, and for positioning when the top cover 1 is pressed down on the other hand. A positioning rod is preset on the bearing platform of the battery. When the top cover 1 is pressed down, the positioning rod passes through the positioning hole, realizing the positioning when the top cover 1 is pressed down, and enabling the battery to be accurately positioned with the bearing platform or workpiece.
[0032] Working principle of the utility model:
[0033] By using bolts and connecting rods, the top cover 1 is connected to the automated equipment, and the equipment is connected through the bolt fixing holes 3, thereby realizing the control of the downward pressure of the top cover 1;
[0034] During battery processing, the battery is grasped and placed on the bottom cover or workpiece for loading by a grasping device, and the downward pressure of the top cover 1 is controlled. At the same time, the positioning rods preset on the bottom cover or workpiece pass through the positioning holes to ensure the accuracy of the downward pressure of the top cover 1;
[0035] During the downward pressure of the top cover 1, the lower end surface of the top cover 1 gradually contacts the upper end surface of the battery until they are in fit. Since the size area of the battery is smaller than the area formed by multiple positioning nuts 5, due to the continuous downward pressure of the top cover 1, the battery is clamped between the top cover 1 and the bottom cover (or workpiece), realizing the pressing of the battery. During this process, the spring 8 in the mounting hole 11 is compressed, and the compression of the spring 8 causes the pressing block 6 to move within the spring cavity 7. One end of the pressing block 6 contacts the bottom cover (or workpiece). The spring 8 and the pressing block 6 are movably matched through the spring 8, avoiding overstress and damage to the battery, realizing the downward pressure limit of the upper and lower positions of the battery, and then clamping and limiting the left and right ends of the battery through the equipment;
[0036] In addition, during the long-term operation of the spring 8, there is excessive fatigue of the spring 8. By controlling the installation height of the positioning nut 5 in the mounting hole 11, the change in the vertical height caused by the excessive fatigue of the spring 8 can be compensated, and the accurate downward pressure control of the battery can still be realized, thus effectively avoiding the complex debugging of the left and right ends of the battery.
