[0002] Deburring is a crucial step in the production of miniature circuit breakers, improving product quality and performance. Deburring devices are specialized for removing burrs from the surface of miniature circuit breakers, effectively improving production efficiency and product quality. While existing deburring devices generally meet user needs, the following issues remain.

[0003] During the production process of a miniature circuit breaker, the shell of the miniature circuit breaker is produced by an injection molding machine. After the production of the miniature circuit breaker shell is completed, a small amount of burrs may be generated on the surface of the miniature circuit breaker shell. When the operator is cleaning the burrs, he may use a handheld grinder to grind the burrs on the miniature circuit breaker shell. However, when grinding, the operator may need to use different grinding wheels according to the location of the burrs. However, since the grinding wheels of general handheld grinders cannot be quickly connected, the operator may not be able to perform fast grinding. For this reason, we propose a deburring device for miniature circuit breaker manufacturing. Utility Model Content

[0023] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0024] Example:

[0025] See also Figure 1 - Figure 6A deburring device for manufacturing a miniature circuit breaker includes an electric handle 1 and a transmission rod 2. The transmission rod 2 is installed at the end of the electric handle 1, and a fixed block 5 is installed at the end of the transmission rod 2. The end of the fixed block 5 is hot-melted with a mounting sleeve 4. The end of the mounting sleeve 4 is elastically connected to a support block 23. The support block 23 and the mounting sleeve 4 are both hot-melted with a sleeve rod 7 on one side thereof. The surface of the sleeve rod 7 is provided with a first spring groove 9 opened on both sides of the mounting sleeve 4. The surface of the sleeve rod 7 is wound with a first spring 8 respectively abutting between the surface of the sleeve rod 7 and the inner wall of the first spring groove 9, and a support block 23 is set between the two groups of support blocks 23. There is a rotating block 18, and the ends of both sides of the rotating block 18 are respectively hot-melted with a rotating shaft 20 that passes through the support block 23, and the ends of both sides of the rotating block 18 are respectively hot-melted with a grinding wheel 3. The surface of the grinding wheel 3 is provided with a receiving groove 6 opened in the middle of the mounting sleeve 4. When the operator needs to adjust a different style of grinding wheel 3, the operator first pulls the grinding wheel 3, and the grinding wheel 3 drives the rotating block 18 to move, so that the rotating block 18 drives the support block 23 to move through the rotating shaft 20. When the support block 23 moves, the support block 23 drives the sleeve rod 7 to slide in the first spring groove 9, and the sleeve rod 7 slides in the first spring groove 9. When the first spring 8 is elastically deformed, the sleeve rod 7 is squeezed by the first spring 8, so that the first spring 8 is elastically deformed. After the first spring 8 is elastically deformed, the first spring 8 avoids the sleeve rod 7, so that the sleeve rod 7 is moved out of the first spring groove 9, and the support block 23 is separated from the mounting sleeve 4. At the same time, the rotating block 18 drives the other grinding wheel 3 to move, so that the other grinding wheel 3 is moved out of the receiving groove 6. Then the operator pushes the rotating block 18, and the rotating block 18 drives the rotating shaft 20 to rotate, so that the rotating block 18 rotates between the two groups of support blocks 23, and the grinding wheels 3 fixed on both sides of the rotating block 18 are adjusted in position. Then the operator releases the rotating block 18. The support block 23 no longer squeezes the first spring 8 through the sleeve rod 7, and the first spring 8 recovers its elastic deformation. The first spring 8 pushes the sleeve rod 7 to move, so that the first spring 8 pushes the sleeve rod 7 to slide in the first spring groove 9, so that the sleeve rod 7 drives the support block 23 to move. The support block 23 drives the rotating block 18 to move through the rotating shaft 20, and the rotating block 18 drives the grinding wheel 3 to move, so that the grinding wheel 3 is inserted into the storage groove 6, which is convenient for storing the grinding wheel 3. By adjusting the positions of the two groups of grinding wheels 3, the operator can adjust the grinding head for grinding, thereby improving the usability of the operator.

[0026] The second spring groove 12 is provided on the side of the transmission rod 2 close to the fixed block 5, and the second spring groove 12 is provided with a push block 11 and a second spring 13 respectively. The ends of the second spring 13 on both sides abut between the surface of the push block 11 and the inner wall of the second spring groove 12. The end of the push block 11 is hot-melt-fitted with a ring 10 sleeved between the fixed block 5 and the surface of the transmission rod 2. The middle part of the push block 11 is hot-melt-fitted with an insertion rod 14, and the end of the insertion rod 14 passes through the second spring groove 12. The surface of the insertion rod 14 is sleeved with a slot 15 opened on the positioning block 17. The surface of the positioning block 17 is sleeved with a positioning groove 16 opened on the end of the transmission rod 2. The positioning block 17 is set in a round cake shape. The positioning groove 16 is set as a round cake-shaped groove that matches the positioning block 17, and a notch is opened on one side of the positioning groove 16 that matches the diameter of the positioning block 17. The positioning block 17 is hot-melt-fitted on the fixed block 5. When the operator needs to replace the installation sleeve 4, the operator first holds his hand on the sleeve After the push block 11 moves, the push block 11 drives the collar 10 to move, and the collar 10 slides on the surface of the transmission rod 2, so that the collar 10 moves away from the notch opened at the front end of the positioning groove 16, and the push block 11 drives the insertion rod 14 to move out of the slot 15, so that the insertion rod 14 and the slot 15 no longer fix the positioning block 17. After that, the operator pulls the transmission rod 2, and the transmission rod 2 drives the positioning groove 16 to move, so that the positioning groove 16 is separated from the surface of the positioning block 17, separating the fixing block 5 from the transmission rod 2, making it convenient for the operator to replace or disassemble the installation sleeve 4.

[0027] In other embodiments, the ring 10 is configured in a circular shape, and a plurality of groups of wavy grooves are provided on the surface of the ring 10. When the operator pulls the ring 10 to move, the circular shape of the ring 10 slides on the surface of the transmission rod 2, and the inner wall of the ring 10 fits with the surface of the transmission rod 2, thereby increasing the stability of the ring 10 sliding on the surface of the transmission rod 2. When the operator holds his hand on the surface of the ring 10, the operator's hand fits with the wavy grooves provided on the surface of the ring 10, thereby increasing the friction force of the operator's hand on the surface of the ring 10 and improving the stability of the operator pulling the ring 10.

[0028] In other embodiments, a rolling groove 19 is provided on one side of the support block 23 and the rotating block 18 that are in contact with each other, and a ball 21 is embedded in the rolling groove 19. The surface of the ball 21 is provided with a guide groove 22 provided on the rotating block 18. The ball 21 is configured as a spherical block, and the guide groove 22 and the rolling groove 19 are configured as arc-shaped grooves that match the ball 21. When the rotating block 18 rotates, the rotating block 18 drives the guide groove 22 to move. Since the inner wall of the guide groove 22 is in contact with the surface of the ball 21, the guide groove 22 drives the ball 21 to move. The ball 21 rolls in the rolling groove 19, and the ball 21 slides on the surface of the guide groove 22, thereby reducing the friction between the rotating block 18 and the support block 23 and increasing the stability of the rotating block 18 in rotating between the support blocks 23.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
