Description

Technical Field

[0001] The utility model provides a battery shell drilling and positioning tool, belonging to the technical field of battery shells. Background Art

[0002] The battery case is a device or outer shell used to contain and protect the internal structure of the battery. It is an indispensable battery accessory. The battery case is mainly composed of an upper shell and a lower shell. The most common installation method is to connect the upper and lower shells together with bolts. Therefore, when producing the battery case, drilling equipment is essential for drilling. When drilling the battery case with drilling equipment, the battery case usually needs to be placed on a positioning tool.

[0003] Existing positioning tooling can basically meet the normal use needs of battery shell drilling, but there are still certain defects: the positioning tooling usually sets a holding component on two opposite sides to press the battery shell tightly. Although this holding method saves the cost of using the holding component, the battery shell is not firmly held and may become loose, affecting the accuracy of the drilling equipment during drilling; and directly using the holding component to hold the battery shell on the top of the tooling table, due to the lack of a limit component, the position of the battery shell initially placed on the top of the tooling table may be disordered, and the placement of the held batteries may be chaotic. Based on this, the utility model provides a battery shell drilling positioning tool. Utility Model Content

[0004] The technical problem solved by the present invention is that: when a pressing assembly is set on two opposite sides to press the battery shell, the pressed battery shell is not firm enough and may become loose, affecting the accuracy of the drilling equipment during drilling; directly using the pressing assembly to press the battery shell on the top of the workbench may cause the pressed battery to be placed in a disorderly manner.

[0005] In order to solve the technical problem, the technical solution provided by the utility model is: a battery shell drilling and positioning tool, including a tooling table, a plurality of pressing components and a limiting component arranged on the outside of the pressing component are arranged around the top of the tooling table, and the limiting component includes a support plate fixedly set on the top of the tooling table, a hollow block is provided on the outer wall of the support plate, a slide is slidably connected to the hollow block, a connecting rod passing through the support plate is provided on one side wall of the slide, a limiting plate is provided on the end of the connecting rod, and a return spring is provided between the other side wall of the slide and the inner wall of the hollow block.

[0006] Furthermore, the holding assembly includes a holding cylinder fixedly arranged on the top of the workbench, the piston rod end of the holding cylinder is rotatably connected to a support block, a cross plate is provided at one end of the bottom of the support block away from the holding cylinder, and holding blocks are symmetrically provided at both ends of the bottom of the cross plate.

[0007] Furthermore, a bolt fixedly connected to the top of the horizontal plate is provided on the top of the support block.

[0008] Furthermore, the two inner side walls of the hollow block are symmetrically provided with limiting rails that match the side walls of the slide.

[0009] Furthermore, a guide plate is provided on the top of the limiting plate, and the inclination angle of the guide plate is 15°-35°.

[0010] Beneficial effects of the utility model:

[0011] 1. By operating the pressing assembly, the battery shell can be firmly and stably pressed and positioned between the surrounding pressing blocks and the top of the workbench, which can effectively prevent the situation of loose clamping, so as to prevent the pressed battery shell from loosening and affecting the accuracy of the drilling equipment during drilling;

[0012] 2. Through the limiting assembly, under the joint action of the return spring, the limiting plate, etc., the battery shell can be initially limited between the limiting plates to avoid the situation where the battery shell is placed in a disorderly manner when the subsequent pressing assembly is pressing.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] According to the attached Figure 1 、 34: The utility model provides a battery shell drilling and positioning tool: it includes a tooling table 1, a plurality of holding components 2 are arranged around the top of the tooling table 1, and a limiting component 3 is arranged on the outside of the holding component 2. The limiting component 3 includes a support plate 4 fixedly arranged on the top of the tooling table 1, and a hollow block 5 is provided on the outer wall of the support plate 4. A slide plate 6 is slidably connected in the hollow block 5. The two inner side walls of the hollow block 5 are symmetrically provided with limiting rails 15 that match the side walls of the slide plate 6, which play a role in limiting the slide plate 6. A connecting rod 7 passing through the support plate 4 is provided on one side wall of the slide plate 6, and a limiting plate 8 is provided on the end of the connecting rod 7. A reset spring 9 is provided between the other side wall of the slide plate 6 and the inner wall of the hollow block 5. A guide plate 16 is provided on the top of the limiting plate 8. The inclination angle is 15°-35°. When it is necessary to drill a hole in the battery shell, the battery shell is placed on the top of the workbench 1 and the battery shell is located between the limit assemblies 3. When the battery shell is lowered between the limit assemblies 3, the bottom of the battery shell moves down and contacts the guide plate 16 before pushing the guide plate 16 outward. The guide plate 16 moves outward and causes the limit plate 8, the connecting rod 7, and the slide plate 6 to move outward, thereby causing the reset spring 9 to be compressed. When the bottom of the battery shell moves down to the limit plate 8, the reset spring 9 in a compressed state at this time has a tendency to rebound and reset, thereby causing the limit plate 8, the connecting rod 7, and the slide plate 6 to move inward until the limit plate 8 is tightly fitted with the side wall of the battery shell, thereby being able to preliminarily limit the battery shell between the limit plates 8.

[0020] According to the attached Figure 1 、 2 3: The pressing assembly 2 includes a pressing cylinder 10 fixedly arranged on the top of the workbench 1, and the piston rod end of the pressing cylinder 10 is rotatably connected to a support block 11, and a cross plate 12 is provided at one end of the bottom of the support block 11 away from the pressing cylinder 10, and holding blocks 13 are symmetrically provided at both ends of the bottom of the cross plate 12. A bolt 14 fixedly connected to the top of the cross plate 12 is provided on the top of the support block 11. The support block 11 is rotated so that the holding block 13 is placed above the battery shell, and the support block 11, the cross plate 12, and the holding block 13 are driven downward by starting the pressing cylinder 10 until the holding block 13 moves down to fit tightly with the top of the battery shell, so that the battery shell can be firmly and stably pressed and positioned between the four sides of the holding blocks 13 and the top of the workbench 1 to prevent the clamped battery shell from loosening and affecting the accuracy of the drilling equipment during drilling.

[0021] Principle of the utility model

[0022] During use, through the limiting component 3, under the joint action of the return spring 9, the limiting plate 8, etc., the battery shell can be initially limited between the limiting plates 8, so as to avoid the subsequent pressing component 2 from placing the pressed battery shell in a disorderly position during pressing. By operating the pressing component 2, the pressing block 13 is moved down until the pressing block 13 moves down to fit tightly with the top of the battery shell, and then the battery shell can be firmly and stably pressed and positioned between the surrounding pressing blocks 13 and the top of the workbench 1. Compared with the traditional method of only setting the pressing component 2 on two opposite sides to press the battery shell, it can effectively prevent the situation of loose clamping, so as to avoid the pressed battery shell from loosening and affecting the accuracy of the drilling equipment during drilling.

[0023] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
