Technical Field

[0001] This utility model belongs to the field of battery processing technology and relates to battery box inspection tools. Background Technology

[0002] The development of new energy vehicles is receiving increasing attention. The core technology of new energy lies in the research and development of battery boxes. The inspection of battery boxes is usually carried out by placing the battery box on a fixture and measuring it manually with measuring tools such as a gap gauge or dial indicator. This measurement method is inefficient and cannot effectively fix the battery box. At the same time, the dial indicator is set at a fixed position and cannot be adjusted or moved. The battery box is large in size and there are many points that need to be measured. Therefore, a new battery box fixture structure is needed. Summary of the Invention

[0003] The purpose of this invention is to provide a battery box inspection tool to solve the problems mentioned in the background art.

[0004] The objective of this utility model can be achieved through the following technical solution: a battery box inspection fixture, including a support frame, a worktable, a battery box body, and a clamping mechanism. The worktable is located at the top of the support frame, and the battery box body is located at the top of the worktable. Multiple evenly distributed clamping mechanisms are located on the top side of the worktable. Each clamping mechanism consists of a support base, a fixed base, a swing arm, a clamping arm, and a clamping head. The support base is fixed to the top center of the worktable. A fixed base is installed on the top of the support base. A clamping arm is installed on the top of the fixed base via a pin. A fixed plate is installed at one end of the clamping arm. A clamping head is located at the bottom of the fixed plate. A support crossbar is provided on the top of the worktable via a detection support. A dial indicator is movably installed on the outside of the support crossbar.

[0005] In the aforementioned battery box inspection fixture, a swing arm is movably connected to the bottom side of the fixed base via a pin, and a handle is connected to the top of the swing arm.

[0006] In the aforementioned battery box inspection fixture, the top end of the swing arm is movably connected to an inner linkage frame via a pin, and the bottom end of the inner linkage frame is movably connected to one end of the clamping arm.

[0007] In the aforementioned battery box inspection fixture, the inspection support is located on the top edge of the workbench, and the top of the inspection support is provided with an installation point, with the end of the support crossbar fixed to the installation point.

[0008] In the aforementioned battery box fixture, a locking hole is provided inside the mounting point, and a locking bolt is threadedly installed at the end of the support crossbar, with one end of the locking bolt threaded into the locking hole.

Detailed Implementation

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] The battery box inspection fixture includes a support frame 1, a worktable 2, a battery box body 3, and a clamping mechanism 4. The worktable 2 is located at the top of the support frame 1, and the battery box body 3 is located at the top of the worktable 2. Multiple evenly distributed clamping mechanisms 4 are located on the top side of the worktable 2. Each clamping mechanism 4 consists of a support base 12, a fixed base 13, a swing arm 14, a clamping arm 17, and a clamping head 19. The support base 12 is fixed to the top center of the worktable 2. The fixed base 13 is installed on the top of the support base 12. The clamping arm 17 is installed on the top of the fixed base 13 via a pin. A fixed plate 18 is installed at one end of the clamping arm 17. The clamping head 19 is located at the bottom of the fixed plate 18. A support crossbar 5 is installed on the top of the worktable 2 via a testing support 10. A dial indicator 9 is movably installed on the outside of the support crossbar 5.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the battery box inspection tool of this utility model has a swing arm 14 movably connected to the bottom side of the fixed base 13 via a pin, and a handle 16 is connected to the top of the swing arm 14.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the battery box inspection tool of this utility model has a swing arm 14 with an inner linkage frame 15 movably connected to the top end via a pin. The bottom end of the inner linkage frame 15 is movably connected to one end of the clamping arm 17. By holding the handle 16 and moving the swing arm 14 upwards, the swing arm 14 drives the clamping arm 17 to move through the inner linkage frame 15 on the inner side. The clamping arm 17 moves downwards toward the bottom of the battery box 3, thereby pressing the clamping head 19 fixed at the bottom of the clamping arm 17 against the side of the battery box 3.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the battery box inspection fixture of this utility model specifically includes a testing support 10 set on the top edge of the workbench 2, with an installation point on the top of the testing support 10. The end of the support crossbar 5 is fixed to the installation point. The testing supports 10 of this application are symmetrically arranged on the top edge of the workbench 2, and multiple sets can be symmetrically arranged. In this way, the support crossbar 5 can be supported and installed by the testing supports 10 at different positions during installation.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the battery box inspection tool of this utility model has a locking hole inside the mounting point. A locking bolt 11 is threadedly installed at the end of the support crossbar 5. One end of the locking bolt 11 is threaded into the locking hole. When fixing the end of the support crossbar 5, it is fixed by the locking bolt 11.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the battery box inspection fixture of this utility model specifically includes a guide rail 6 at the top of the supporting crossbar 5, a slider 7 slidably mounted on the outside of the guide rail 6, a mounting base 8 at the top of the slider 7, and a dial indicator 9 fixed to the top of the mounting base 8. The guide rail 6 in this application mainly guides and supports the slider 7. It is made of metal, and the guide rail 6 is a commercially available device known to those skilled in the art. Here, we are simply using it without making any structural or functional improvements, so we will not elaborate further. The dial indicator 9 measures the height of various parts of the battery box 3. The dial indicator 9 is also a commercially available device known to those skilled in the art. Here, we are simply using it without making any structural or functional improvements, so we will not elaborate further.

[0027] In operation, the battery box inspection fixture of this utility model involves placing the battery box 3 on top of the workbench 2, and then fixing the sides of the battery box 3. The handle 16 can be held, and the swing arm 14 can be moved upwards. The swing arm 14, through the inner linkage frame 15, drives the clamping arm 17 to move. The clamping arm 17 presses downwards towards the bottom of the battery box 3, thereby pressing the clamping head 19 fixed at the bottom of the clamping arm 17 against the side of the battery box 3, thus clamping and limiting the battery box 3, facilitating the inspection of the battery box. The battery box 3 is inspected. A slidable dial indicator 9 is installed on the support crossbar 5 via a guide rail 6. The dial indicator 9 can be used to inspect the surface of the battery box 3. At the same time, the position of the dial indicator 9 can be adjusted by sliding the slider 7 to inspect different points on the battery box 3. The support crossbar 5 is fixed to the inspection support 10 by locking bolts 11. This allows for easy disassembly of the support crossbar 5, changing the position of the support crossbar 5, and adjusting the dial indicator 9 to inspect different areas of the battery box 3.
