The circuit breaker molded case is a shell that protects the internal components of the circuit breaker and is usually made of plastic material. During the manufacturing process, the edges of the circuit breaker molded case need to be ground to ensure its smooth appearance and avoid harming the operator.

[0003] Among them, it is found through searching that the utility model patent with patent application number CN202221888479.3 discloses an edge grinding device for molded case circuit breaker production, comprising a bottom plate, the top of the bottom plate is connected to a box body, the top of the bottom plate is connected to a chip collecting box, the top of the bottom plate is connected to a lower grinding motor, the output end of the lower grinding motor is connected to a lower grinding shaft, one end of the lower grinding shaft is connected to a lower grinding sheet, and the top of the box body is connected to a workbench;

[0004] When this structure is in use, the rotating handle on the threaded rod is rotated to make the two threaded rods move relative to each other, so that the clamping heads on the two threaded rods are clamped together, so that the molded case circuit breaker is clamped and fixed, which is more convenient for grinding.

[0025] As attached Figure 1-6The circuit breaker plastic case edge grinding device shown in the figure has a grinding assembly arranged on the bottom plate 1. When edge grinding, the electric push rod 5 can drive the support rod 6 to move, so that the interference shaft 7 can contact the grinding belt 4. The grinding belt 4 is deformed by the traction force when the interference shaft 7 moves and approaches the placement block 14, and the circuit breaker plastic case on the placement block 14 is pressurized, thereby improving the edge grinding effect of the device. When the grinding belt 4 is deformed, it will drive the second transmission roller 9 to move along the guide groove 11 through the slider 12, and make the spring 13 stressed. The slider 12 is driven to reset through the elasticity of the spring 13 itself, thereby ensuring that the grinding belt 4 is always in a taut state when deformed, ensuring the stability of the grinding belt 4 when rotating, and the specific structure of the assembly is arranged as follows;

[0026] The grinding assembly includes a vertical plate 2 arranged on the top of the bottom plate 1 for support, a support frame 3 installed on the bottom plate 1 is arranged on one side of the vertical plate 2, and an electric push rod 5 for driving is arranged in the middle of the support frame 3;

[0027] A support rod 6 is provided at the output end of the electric push rod 5. A mounting groove is provided on the support rod 6, and a resistance shaft 7 is rotatably connected in the mounting groove. A grinding belt 4 for grinding is provided on the outer side of the resistance shaft 7. A first transmission roller 8 is provided on one side of the inner cavity of the grinding belt 4, and a second transmission roller 9 is provided on the other side of the inner cavity of the grinding belt 4. A motor 10 for driving the first transmission roller 8 to rotate is provided on one side of the bottom of the support frame 3, and the motor 10 is detachably connected to the support frame 3.

[0028] Guide grooves 11 for guiding are provided at both ends of the second transmission roller 9 and on the surface of the support frame 3, and a slider 12 is slidably connected in each guide groove 11. The slider 12 is rotatably connected to the second transmission roller 9. Springs 13 for supporting are provided on both sides of the slider 12. A placement block 14 is provided on the side of the top of the vertical plate 2 facing the support frame 3, and a slot 15 for limiting the position of the material is provided on the placement block 14.

[0030] At the same time, when edge grinding is performed, the first transmission roller 8 is driven to rotate by the motor 10, so that the grinding belt 4 and the second transmission roller 9 are rotated to grind the circuit breaker plastic shell. At the same time, when edge grinding is performed, the support rod 6 can be driven to move by the electric push rod 5, so that the resistance shaft 7 can contact the grinding belt 4. The grinding belt 4 is deformed by the traction force when the resistance shaft 7 moves and approaches the placement block 14, and the circuit breaker plastic shell on the placement block 14 is pressurized, thereby improving the edge grinding effect of the device;

[0031] When the grinding belt 4 is deformed, it will drive the second transmission roller 9 to move along the guide groove 11 through the slider 12, and make the spring 13 stressed. The elasticity of the spring 13 drives the slider 12 to reset, thereby ensuring that the grinding belt 4 is always in a taut state when deformed, ensuring the stability of the grinding belt 4 when rotating.

[0032] Different from the prior art, the present application discloses a circuit breaker plastic case edge grinding device, which can drive the support rod 6 to move through the electric push rod 5 during edge grinding, so that the interference shaft 7 can contact the grinding belt 4. The grinding belt 4 is deformed by the traction force of the interference shaft 7 when it moves and approaches the placement block 14, so as to pressurize the circuit breaker plastic case on the placement block 14, thereby improving the edge grinding effect of the device, and when the grinding belt 4 is deformed, it will drive the second transmission roller 9 to move along the guide groove 11 through the slider 12, and make the spring 13 subject to force, and the slider 12 is driven to reset through the elasticity of the spring 13 itself, thereby ensuring that the grinding belt 4 is always in a taut state when it is deformed, and ensuring the stability of the grinding belt 4 when it rotates.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
