Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and more specifically, it relates to a deburring device for metal stamping parts. Background Art

[0002] During the metal stamping process, sharp burrs are formed on the surface of metal parts due to the interaction between the stamping die and the material. These burrs not only affect the appearance quality of the product but may also cause inconvenience in subsequent assembly and use. Therefore, deburring is an important step in the processing of metal stamping parts. For small and sharp burrs, mechanical deburring, such as using a grinding machine, is usually chosen.

[0003] During the deburring process, it is difficult to clamp and fix the metal stamping parts, making it difficult to accurately position the workpiece. This may result in uneven deburring, affecting the surface quality of the workpiece and increasing operational risks. At the same time, the grinding steel brush will wear during the deburring process, but the existing grinding steel brush is not easy to install and replace, which may lead to the steel brush not being securely installed. This may result in uneven wear during the grinding process, affecting the grinding quality and efficiency, leading to prolonged equipment downtime for maintenance, increasing maintenance costs, and reducing the efficiency of equipment use.

A friction strip 24 is rotatably provided on the fastening screw 23. An anti-slip texture 25 is provided on the steering plate 5.

[0030] In this embodiment, during use, the metal stamping part is placed between the clamping plates 7 on the workbench 2. The clamping screw 6 is rotated, which drives the clamping plates 7 and the clamping slide bar 8 to move, thereby clamping and fixing the position of the metal stamping part. The fastening screw 23 is loosened, causing the friction strip 24 to leave the anti-slip texture 25, which can drive the metal stamping part and the steering plate 5 to rotate. After adjusting the support direction of the metal stamping part, the fastening screw 23 is tightened, and the friction strip 24 on the fastening screw 23 moves to the side of the anti-slip texture 25. The friction between the friction strip 24 and the anti-slip texture 25 fixes the direction of the steering plate 5 and the metal part. Then, the drive cylinder 20 adjusts the height of the drive frame 21 through the limit rod 22, thereby adjusting the height of the drive motor 9 and the grinding head 10. The grinding head 10 is a wire brush, and the burrs on the metal part are removed by rotating the grinding head 10.

[0031] Please see Figures 4-5As one embodiment of the connecting device: the drive rod 11 is provided with a movable thread 26, and a movable sleeve 27 is threadedly connected to the movable thread 26. The movable sleeve 27 is rotatably connected to the extrusion sleeve 18. A sliding block 28 is provided inside the drive rod 11.

[0032] More specifically, during the installation of the grinding head 10, the drive rod 11 is mounted on the motor shaft of the drive motor 9, and the connecting rod 12 is mounted on the grinding head 10. The connecting rod 12 is inserted into the drive rod 11 through the cooperation of the sliding block 28 and the sliding groove 29. Then, the moving sleeve 27 is rotated, and the moving sleeve 27 rotates and moves downward on the moving thread 26, driving the pressing sleeve 18 to move downward. When the pressing sleeve 18 moves downward, it drives the pressing plate 17 to press the second return spring 32. 7 drives the locking rod 13 and locking connector 14 to move, stretching the first return spring 31, so that the locking connector 14 extends into the locking hole 15, thereby fixing the position of the connecting rod 12 and the grinding head 10. When disassembling the connecting rod 12, the moving sleeve 27 is rotated in the opposite direction. The moving sleeve 27 drives the pressing sleeve 18 to move upward, and the locking connector 14 and locking rod 13 are reset by the first return spring 31. The pressing plate 17 is reset by the second return spring 32, thereby disassembling the connecting rod 12 and the grinding head 10.

[0033] In summary, during the use or operation of the overall equipment: When in use, the metal stamping part is placed between the clamping plates 7 on the worktable 2. The clamping screw 6 is rotated, which drives the clamping plates 7 and the clamping slide bar 8 to move, thereby clamping and fixing the position of the metal stamping part. The fastening screw 23 is loosened, causing the friction strip 24 to move away from the anti-slip texture 25, which can drive the metal stamping part and the steering plate 5 to rotate. After adjusting the support direction of the metal stamping part, the fastening screw 23 is tightened, and the friction strip 24 on the fastening screw 23 moves to the side of the anti-slip texture 25. The friction between the friction strip 24 and the anti-slip texture 25 fixes the direction of the steering plate 5 and the metal part. Then, the drive cylinder 20 adjusts the height of the drive frame 21 through the limit rod 22, thereby adjusting the height of the drive motor 9 and the grinding head 10. The grinding head 10 uses a wire brush, and the burrs on the metal part are removed by rotating the grinding head 10.

[0034] During the installation of the grinding head 10, the drive rod 11 is mounted on the motor shaft of the drive motor 9, and the connecting rod 12 is mounted on the grinding head 10. The connecting rod 12 is inserted into the drive rod 11 through the cooperation of the sliding block 28 and the sliding groove 29. Then, the moving sleeve 27 is rotated, and the moving sleeve 27 rotates on the moving thread 26 and moves downward, driving the pressing sleeve 18 to move downward. When the pressing sleeve 18 moves downward, it drives the pressing plate 17 to press the second return spring 32. Through the pressing plate 17, the second return spring 32 is pressed. The moving locking rod 13 and locking connector 14 move, stretching the first return spring 31, causing the locking connector 14 to extend into the locking hole 15, thereby fixing the position of the connecting rod 12 and the grinding head 10. When disassembling the connecting rod 12, the moving sleeve 27 is rotated in the opposite direction, and the moving sleeve 27 drives the pressing sleeve 18 to move upward. The first return spring 31 drives the locking connector 14 and locking rod 13 to reset, and the second return spring 32 drives the pressing plate 17 to reset, thereby disassembling the connecting rod 12 and the grinding head 10.
