Description

Technical Field

[0001] This utility model relates to the field of power battery box processing technology, specifically a positioning device for internal cutting and processing of power battery boxes. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the performance and safety of power batteries, as core components, have attracted much attention. The internal structure of power battery boxes is complex. In order to meet the assembly requirements of the complex internal structure of power battery boxes, it is often necessary to perform cutting and machining on the inside during the production and processing of power battery boxes.

[0003] Currently, during machining, a positioning device is required to locate the power battery box. Since the distance between the positioning devices cannot be adjusted, it can only locate power battery boxes of a single size. When machining battery boxes of different specifications, the positioning components need to be changed frequently. This is not only cumbersome and time-consuming, but also prone to errors during the replacement process, which can lead to a decrease in positioning accuracy and affect the quality of the machining.

[0004] In the prior art, such as the one disclosed in CN221716224U, a machining fixture for a battery box is used for positioning the battery box. It includes: a first support base, comprising a mounting portion and a limiting portion perpendicular to each other; the mounting portion is used to connect to machining equipment; a limiting groove is formed at the top of the limiting portion for placing the battery box to perform initial positioning; and a limiting device, with multiple limiting devices distributed circumferentially along the limiting portion. The limiting device has a first state and a second state. In the first state, the limiting device locks the battery box within the limiting groove to prevent separation of the battery box from the limiting groove; in the second state, the limiting device releases the lock on the battery box. However, there is no related structure for adjusting the positioning position. Therefore, when positioning power battery boxes of different specifications, the positioning components need to be frequently replaced. This results in a decrease in positioning accuracy due to errors during replacement, which in turn affects the machining quality. Therefore, we need to propose a positioning device for internal machining of power battery boxes. Utility Model Content

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a positioning device for internal cutting and processing of a power battery box, including a mounting frame 1 installed on a cutting device, a positioning seat 2 integrally formed at the top of the mounting frame 1, adjustment grooves are provided around the positioning seat 2, a movable seat 3 is slidably connected to the inner cavity of the adjustment groove, a support frame 4 is bolted to the bottom end of the movable seat 3, a first push rod 5 is bolted to the bottom end of the support frame 4, a positioning post 6 for positioning the power battery box is bolted to the push rod part of the first push rod 5, an movable hole adapted to the positioning post 6 is provided on the surface of the movable seat 3, and an adjustment component 7 for changing the positioning position is also installed on the upper surface of the positioning seat 2;

[0024] First, the positioning device is installed on the cutting table of the cutting equipment via the mounting bracket 1. The power battery box to be processed is placed on the positioning seat 2. The moving component is activated to adjust the position of the surrounding moving seats 3 in the adjustment groove, so that the moving seats 3 drive the positioning column 6 to move towards the surface of the power battery box. At the same time, the first push rod 5 is activated according to the height of the power battery box, so that the first push rod 5 pushes the positioning column 6 to extend and retract. The height of the positioning column 6 is adjusted according to the height of the power battery box. Finally, the moving seats 3 drive the positioning column 6 to fit against the surface of the power battery box, thereby achieving the positioning of the power battery box. Through the above scheme, the positioning device can position power battery boxes of different specifications, avoid frequent replacement of positioning components, reduce the impact on the cutting quality, and improve the positioning accuracy of the power battery box.

[0025] The upper surface of the positioning seat 2 is provided with scale lines, which are distributed on both sides of the adjustment groove. By setting the scale lines, when adjusting the position of the positioning post 6 on the positioning seat 2, the distance of adjustment of the positioning post 6 on the positioning seat 2 can be understood by observing the scale lines, thereby further improving the positioning accuracy of the power battery box.

[0026] The inner wall of the support frame 4 is fixedly connected to the support plate 8. The surface of the positioning column 6 is provided with a support groove that matches the support plate 8. By setting the support plate 8, the two sides of the positioning column 6 can be supported, which improves the stability of the positioning column 6 when it is extended and retracted, and prevents the position angle of the positioning column 6 from shifting after being subjected to force.

[0027] The top of the positioning column 6 is bolted to a positioning block 9, and the top of the positioning block 9 is bolted to a positioning sensor 10. The positioning sensor 10 can sense the position of the power battery box. The positioning sensor 10 is connected to the control computer. The positioning sensor 10 can further sense the distance between the positioning column 6 and the power battery box, so as to facilitate the adjustment of the position of the positioning column 6 and further improve the positioning accuracy of the positioning column 6 for the power battery box.

[0028] The adjustment assembly 7 includes a second push rod 71, which is bolted to the upper surface of the positioning seat 2. A connecting block 72 is bolted to the push rod part of the second push rod 71. The bottom end of the connecting block 72 is bolted to the top end of the movable seat 3. When the second push rod 71 is activated, the push rod part of the second push rod 71 pushes the movable seat 3 to move through the connecting block 72, causing the movable seat 3 to move the positioning column 6 within the adjustment groove. By adjusting the position of the movable seat 3 within the adjustment groove, the position of the positioning column 6 is adjusted, allowing the positioning column 6 to position power battery boxes of different sizes.

[0029] The surface of the movable seat 3 has a through hole, and a support rod 11 is slidably inserted into the inner cavity of the through hole of the movable seat 3. Both sides of the support rod 11 are fixedly connected to the inner side wall of the adjustment groove. By setting the support rod 11, the two sides of the movable seat 3 can be supported, which improves the stability of the movable seat 3 when it moves in the adjustment groove and prevents the angle of the movable seat 3 from shifting when it moves.

[0030] It also includes a clamping mechanism 12 for clamping and fixing the power battery box. The clamping mechanism 12 is provided in several groups and is installed on the upper surface of the movable seat 3. The clamping mechanism 12 can be used to clamp and fix the power battery box, avoiding the phenomenon of shaking of the power battery box during the cutting process, and further improving the stability of the power battery box during processing.

[0031] The clamping mechanism 12 includes a clamping cylinder 121, which is bolted to the top of the movable seat 3. A clamping block 122 is bolted to the output end of the clamping cylinder 121. A pressure sensor 123 is installed at the bottom of the clamping block 122. When the clamping cylinder 121 is activated, the output end of the clamping cylinder 121 drives the clamping block 122 to rotate and extend. After the clamping block 122 rises, it rotates to the top of the power battery box. Then, the clamping block 122 descends and contacts the top of the power battery box. The clamping block 122 contacts the power battery box through the pressure sensor 123. Then, according to the data transmitted by the pressure sensor 123, the clamping force of the clamping cylinder 121 on the power battery box is adjusted.

[0032] The clamping cylinder 121 is connected to an air compressor via a connecting pipe. The compressor supplies air to the clamping cylinder 121. The clamping cylinder 121 in this application is a very mature prior art. There is no further protection or limitation on the clamping cylinder 121. Products with the same function can be purchased on the market for use.

[0033] In this embodiment, both the first push rod 5 and the second push rod 71 are electric push rods. The first push rod 5 and the second push rod 71 are connected to a power supply device via a power cord. At the same time, the first push rod 5 and the second push rod 71 are connected to a control button for controlling the extension and retraction of the push rod via the power cord. Electric push rods are a mature existing technology in the mechanical field. This application does not further protect or limit the first push rod 5 and the second push rod 71. Both the first push rod 5 and the second push rod 71 can be purchased on the market and used as products with equivalent functions.

[0034] The positioning sensor 10 and pressure sensor 123 mentioned in this embodiment are mature existing technologies. This application does not further protect or limit the positioning sensor 10 and pressure sensor 123. Both the positioning sensor 10 and pressure sensor 123 can be purchased on the market and used as products with the same functions. The positioning sensor 10 and pressure sensor 123 are connected to the control computer through power lines and signal lines, and the data sensed by the positioning sensor 10 and pressure sensor 123 is transmitted to the control computer for display.

[0035] In practical use: First, the positioning device is installed on the cutting table of the cutting equipment via the mounting bracket 1. The power battery box to be processed is placed on the positioning seat 2. Then, the height of the positioning column 6 is adjusted according to the height of the power battery box. The first push rod 5 is activated to push the positioning column 6 to move, causing the positioning column 6 to extend and retract on the surface of the positioning seat 2. After adjusting the height of the positioning column 6, the second push rod 71 is activated. The push rod part of the second push rod 71 pushes the moving seat 3 to move via the connecting block 72, causing the moving seat 3 to move the positioning column 6, thereby changing the positioning position of the positioning column 6 relative to the power battery box. When the positioning columns 6 around the positioning seat 2 are in contact with the surface of the power battery box, the positioning of the power battery box is achieved. To improve the positioning effect of the power battery box, the clamping cylinder 121 is then activated. The output end of the clamping cylinder 121 first drives the clamping block 122 to rise. After rising to a certain height, the output end drives the clamping block 122 to rotate directly above the power battery box. Then, the clamping block 122 retracts, causing the pressure sensor 123 to contact the surface of the power battery box. By observing the data transmitted by the pressure sensor 123, the clamping force of the output end of the clamping cylinder 121 is adjusted. Through the above scheme, the positioning device can position power battery boxes of different specifications, avoid frequent replacement of positioning components, reduce the impact on the cutting quality, and improve the positioning accuracy of the power battery box.
