Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery plastic shell installation, in particular to a pressing clamp for installing a lithium battery plastic shell. Background Art

[0002] At present, the outer packaging of the battery of an electric vehicle is composed of two plastic shells. During assembly, the battery core is manually placed in the plastic shell and then the two plastic shells are tightened with screws. In order to achieve the waterproof and dustproof functions, it is necessary to add a layer of sealing sleeve or buffer cotton at the junction of the two plastic shells. The buffer cotton increases the distance between the two shells. When assembling the two plastic shells, the two plastic shells are first clamped with the buffer cotton. Due to the strength of the workers' palms, the two plastic shells are slightly displaced, which causes the screw holes on the plastic shells to be misaligned, resulting in the screws slipping, causing the product plastic shell to be scrapped, causing certain losses to the company;

[0003] The existing Chinese patent CN202219467U discloses a clamping fixture for installing a lithium battery plastic shell. The clamping fixture for installing a lithium battery plastic shell aligns the through hole on the pressing plate with the screw hole of the product shell, and is pressed down by a cylinder so that the upper and lower shells of the product are evenly pressed together while keeping them horizontal. Then, an electric screwdriver is used to drive screws through the through hole of the pressing plate to complete the installation of the battery shell.

[0004] However, there are certain size differences between batteries of different specifications. For example, the size of a 10AH battery is approximately 151mm long, 98mm wide, and 94mm high, and the size of a 20AH battery is approximately 181mm long, 77mm wide, and 170mm high. Therefore, there are differences in the positions of screw holes on different batteries. Using a pressure plate with fixed specifications cannot ensure that different battery casings can be pressed and installed. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] See also Figure 1-Figure 5 The utility model provides a technical solution: a clamping fixture for installing a lithium battery plastic shell, comprising a bottom plate 1, a cylinder 2 is fixedly installed on the top of the bottom plate 1, and a pressing mechanism 3 is fixedly installed on the top of the cylinder 2;

[0024] The pressing mechanism 3 includes a mounting frame 301, which is fixedly mounted on the top of the cylinder 2. A positioning plate 302 is slidably arranged inside the mounting frame 301. Two positioning plates 302 are arranged. A friction plate 303 is fixedly mounted on the top of the positioning plate 302. A pressing plate 304 is slidably arranged inside the mounting frame 301. The pressing plate 304 is located above the friction plate 303. A pressing component 305 is fixedly mounted on the top of the pressing plate 304. A threaded hole 306 is provided on the top of the positioning plate 302. , a plurality of threaded holes 306 are provided, and are evenly spaced on the positioning plate 302. By providing a positioning plate 302 that can slide in the mounting frame 301, the position of the positioning plate 302 can be adjusted according to the size of the shell, so that a threaded hole 306 on the positioning plate 302 is aligned with the threaded hole on the shell. After the threaded hole 306 is aligned with the threaded hole on the shell, the mounting frame 301 is driven downward by the cylinder 2, and then the positioning plate 302 is driven downward, so that the positioning plate 302 is pressed on the shell, and the upper and lower shells of the product are evenly pressed together by the force, and the positioning plate 302 is fixed by pressing the clamping plate 304 on the friction plate 303. That is, after the position of the positioning plate 302 is adjusted, the clamping plate 304 is pressed downward by the clamping component 305, so that the clamping plate 304 is tightly pressed on the friction plate 303 to fix the positioning plate 302;

[0025] The clamping component 305 includes a fixing frame 3054, which is fixedly installed on the top of the mounting frame 301. The center of the fixing frame 3054 is threadedly connected with a threaded rod 3053, and the bottom end of the threaded rod 3053 is rotatably connected with a connecting frame 3052 through a bearing. A connecting rod 3051 is fixedly installed on the bottom of the connecting frame 3052. The bottom end of the connecting rod 3051 movably passes through the top of the mounting frame 301, and the bottom end of the connecting rod 3051 is fixedly connected to the top of the clamping plate 304. The connecting frame 3052 is lifted and lowered by rotating the threaded rod 3053, thereby driving the connecting rod 3051 to lift and lower. The lifting of the connecting rod 3051 drives the clamping plate 304 to lift and lower. When the position of the positioning plate 302 is adjusted, the clamping plate 304 rises. When the positioning plate 302 is fixed, the clamping plate 304 descends and presses on the friction plate 303.

[0026] The outer wall of the positioning plate 302 is fixedly mounted with an extension plate 10. The extension plates 10 on the two positioning plates 302 are staggered. The extension plates 10 are arranged to increase the area where the positioning plates 302 press on the shell, reduce the pressure on the shell, and prevent the shell from being deformed by compression while ensuring that the shell is pressed downward;

[0027] A support plate 4 is placed on the top of the bottom plate 1, and a positioning pin 6 is fixedly installed on the bottom of the support plate 4. The positioning pin 6 is inserted into the positioning hole on the top of the bottom plate 1. The positioning pin 6 is provided to locate the position of the support plate 4 on the bottom plate 1, and the product shell is held by the support plate 4;

A pin 7 is threadedly connected to the inner wall of the threaded hole 2 5. A rotating cylinder 8 is rotatably sleeved on the outer wall of the pin 7. According to the size of the product shell, the pin 7 is screwed into the corresponding threaded hole 2 5, so that the rotating cylinder 8 on the pin 7 limits the shell to prevent the shell from moving when pressed;

[0029] A groove is provided at the bottom of the base plate 1, and an anti-skid pad 9 is fixedly installed on the inner wall of the groove. The bottom of the anti-skid pad 9 extends out from the groove. The anti-skid pad 9 is provided to increase the friction between the base plate 1 and the ground to prevent the base plate 1 from sliding during the pressing process, causing the outer shell to shake.

[0030] Working principle: When in use, according to the shell size of the same batch, move the positioning plate 302 so that a threaded hole 306 on the positioning plate 302 can be aligned with the threaded hole on the shell, and then rotate the threaded rod 3053 to make the connecting frame 3052 rise and fall, thereby driving the connecting rod 3051 to rise and fall, and the lifting and lowering of the connecting rod 3051 drives the pressing plate 304 to rise and fall. When adjusting the position of the positioning plate 302, the pressing plate 304 rises, and when fixing the positioning plate 302, the pressing plate 304 descends and presses on the friction plate 303, fixes the positioning plate 302, aligns the upper and lower shells of the product and places them on the support plate 4, aligns the threaded hole on the shell with the preset threaded hole 306 when placing, turns on the cylinder 2 to drive the mounting frame 301 to move downward, thereby driving the positioning plate 302 to move downward, so that the positioning plate 302 is pressed down on the shell, presses the shell downward, and then uses a tool to screw the screw into the threaded hole on the shell.
