Description

Technical Field

[0001] This utility model belongs to the field of lead-acid battery assembly technology, specifically relating to a deburring tool for holes in lead-acid battery casings. Background Technology

[0002] During the production of lead-acid batteries, holes are drilled in the battery casing to facilitate welding. However, during drilling, wear or improper fit of the punching die can result in burrs on the hole edges. These burrs can trap plastic fragments during welding, leading to poor weld quality and impacting the overall quality of the lead-acid battery casing. Traditional manual deburring methods are inefficient and leave plastic debris, affecting subsequent welding processes. Alternatively, hot-melt methods (open flame or hot air melting) can cause deformation of PE plastic due to its low melting point. Therefore, a highly efficient and controllable deburring tool is needed to improve deburring efficiency and quality, thereby enhancing the overall quality of lead-acid battery casings.

Detailed Implementation

[0020] 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.

[0021] Please see Figures 1 to 3 This utility model provides an embodiment of a deburring fixture for holes in lead-acid battery casings, comprising a positioning base 1, a depth adjustment structure 2, a rotating tool assembly 3, and a chip collection system 4.

[0022] The positioning base 1 includes a base, a blocking cylinder 11, and a clamping and positioning device 12. The base has a rectangular frame structure with adjustable feet at the bottom and is installed at the deburring station of the battery casing conveyor roller. The blocking cylinder 11 and the clamping and positioning device 12 are located on the top of the base and are used to fix the battery casing.

[0023] The depth adjustment structure 2 is a conventional three-dimensional robotic arm, mounted on top of the base via a mounting bracket. It specifically includes front and rear slide rails 21, upper and lower slide rails 22, left and right slide rails 23, and an integrated pressure sensor 24. The upper and lower slide rails 22 have vertically sliding sliders, allowing for adjustment in vertical, horizontal, and forward / backward positions to accommodate different hole layouts. The integrated pressure sensor 24, mounted on the upper and lower slide rails 22, monitors cutting resistance and automatically triggers an emergency stop protection mechanism when limits are exceeded.

[0024] The rotary cutter assembly 3 is mounted on the upper and lower sliders and includes a cutter 31, a drive motor 32, a flexible coupling 33, a moving mold 34, and a stationary mold 35. The drive motor 32 is connected to the cutter 31 via the flexible coupling 33. The cutter 31, drive motor 32, and flexible coupling 33 are mounted inside the moving mold 34. The stationary mold 35 is fixed to one clamping end of the transverse clamping cylinder 36 via a stationary mold bracket. The moving mold 34 is fixed to the other clamping end of the transverse clamping cylinder 36 via a moving mold bracket. The transverse clamping cylinder 36 is mounted and fixed on the upper and lower sliders. The moving mold 34 and the stationary mold 35 can be clamped onto the lead-acid battery casing containing the holes to be deburred by the clamping action of the transverse clamping cylinder 36. The diameter of the cutter head of the cutter 31 is adapted to the hole in the casing. The surface of the cutter head is provided with a spiral chip removal groove 311, and the cutting edge is blunted to avoid scratching the hole wall. A sealing gasket 5 is installed between the moving mold 34 and the stationary mold 35 for tightening and sealing. The rotary cutter assembly 3 can be designed in multiple ways to match the positions of multiple holes in a single battery casing, thereby deburring multiple holes in a single casing simultaneously.

[0025] The chip collection system 4 is located below the base and includes a vacuum pump 41, hoses 42, a removable waste box 43, and a support base. The removable waste box 43 is a closed box, and the vacuum pump 41 is mounted on the side of the removable waste box 43. The vacuum pump 41 and the removable waste box 43 are mounted on the support base. One end of the two hoses 42 is connected to the removable waste box 43, and the other end is connected to the moving mold 34 and the stationary mold 35 respectively. During the rotation of the cutter 31, the moving mold 34 and the stationary mold 35 clamp and seal together. The vacuum pump 41 starts and draws the cutting chips into the removable waste box 43 through the hoses 42.

[0026] After the outer casing reaches the deburring station via the roller conveyor, the blocking cylinder 11 and clamping positioning device 12 position and fix the outer casing. The position parameters of the front and rear slide rails 21, upper and lower slide rails 22, and left and right slide rails 23 of the depth adjustment structure PLC program are adjusted to align the tool 31 with the target hole. The cutting depth and vertical feed distance are set. After the program is started, the rotating tool assembly 3 descends to the designated position, and the moving mold 34 and the stationary mold 35 clamp and seal. At the same time, the drive motor 32 is started to control the rotation of the tool 31 and vertical feed to cut and deburr. The flexible coupling 33 buffers the vibration of the tool 31, and the integrated pressure sensor 24 monitors the cutting resistance. If the resistance exceeds the limit, the emergency stop protection is automatically triggered. During the deburring process, the vacuum pump 41 is started, and the cutting chips are discharged along the spiral chip discharge groove 311 on the surface of the tool 31. Then, they are sucked out by the negative pressure through the hose 42 to the removable waste box 43 to prevent chip residue from affecting the subsequent welding quality. After the deburring process is completed, the tool 31 is reset, the rotating tool assembly 3 rises to wait for the next hole to be deburred, and then the above actions are repeated.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
