[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0020] Example 1:

[0021] Reference Figure 1 、 Figure 2 、 Figure 3A clamping device for circuit breaker production includes a base plate 1, and also includes: four slide grooves 101 equidistantly arranged on the base plate 1, wherein each slide groove 101 is slidably connected to a slider 102, and a spring 103 is provided in the slide groove 101, one end of the spring 103 is fixedly connected to the slider 102, and the other end is fixedly connected to the inner wall of the slide groove 101; a connecting rod 3 is fixedly connected to the slider 102; and an L-shaped clamping plate 301 is fixedly connected to the connecting rod 3.

[0022] It also includes a protection pad 302 , which is fixedly mounted on the L-shaped clamping plate 301 .

[0023] When the circuit breaker needs to be clamped, the circuit breaker is placed in the center of the base plate 1. Since the spring 103 is in a natural state or pre-compressed state, after the circuit breaker is placed, the circuit breaker will generate an outward thrust on the L-shaped clamping plate 301. At this time, the L-shaped clamping plate 301 transmits force to the slider 102 through the connecting rod 3, causing the slider 102 to slide in the slide groove 101 in a direction away from the center of the circuit breaker. The spring 103 is further compressed. At the same time, the reaction force of the compressed spring 103 acts on the L-shaped clamping plate 301 through the slider 102 and the connecting rod 3, so that the L-shaped clamping plate 301 generates an inward clamping force on the circuit breaker, thereby clamping the circuit breaker. At the same time, the protective pad 302 on the L-shaped clamping plate 301 can protect the surface of the circuit breaker from being scratched.

[0024] Since the L-shaped clamping plate 301 can slide in the slide groove 101 through the connecting rod 3 and the slider 102, the clamping device can adapt to circuit breakers of different sizes. When a smaller-sized circuit breaker is placed, the elastic force of the spring 103 will cause the slider 102 to slide toward the center in the slide groove 101, thereby driving the L-shaped clamping plate 301 to move toward the center, effectively clamping the smaller-sized circuit breaker. On the contrary, when a larger-sized circuit breaker is placed, the circuit breaker will push open the L-shaped clamping plate 301, causing the slider 102 to slide outward in the slide groove 101, compressing the spring 103 until the L-shaped clamping plate 301 is in close contact with the surface of the circuit breaker, thereby achieving clamping. Therefore, the versatility of the clamping device is improved, and there is no need to frequently replace the clamp for circuit breakers of different sizes.

[0025] Example 2:

[0026] Reference Figure 2 、 Figure 3 A clamping device for circuit breaker production is substantially the same as that of Example 1, further comprising a mounting cylinder 4, a base plate 1 being rotatably connected to the mounting cylinder 4, a plurality of balls 401 being equidistantly arranged around the top circumference of the mounting cylinder 4, the balls 401 being in contact with the base plate 1;

[0027] The motor 5 is fixedly mounted on the inner wall of the top of the mounting tube 4, and the base plate 1 is fixedly connected to the output end of the motor 5;

[0028] When the circuit breaker needs to be rotated, the motor 5 on the inner wall of the top of the mounting cylinder 4 is started. The output end of the motor 5 drives the base plate 1 to rotate, and the base plate 1 rotates on the mounting cylinder 4. During the rotation process, the balls 401 arranged at equal intervals around the top of the mounting cylinder 4 come into contact with the base plate 1. The rolling of the balls 401 effectively reduces the friction during the rotation of the base plate 1, making the rotation of the base plate 1 more stable and smooth, and facilitating the production and processing of the clamped circuit breaker from different angles.

[0029] Example 3:

[0030] Reference Figure 2 、 Figure 4 A clamping device for circuit breaker production is basically the same as that of Example 1. Furthermore, guide grooves 2 are provided on both inner walls of the slide 101. Guide blocks 201 are slidably connected in the guide grooves 2. The guide blocks 201 are integrally formed with the slider 102.

[0031] During the sliding process of the slider 102, the guide blocks 201 integrally formed on the slider 102 slide in the guide grooves 2 on the inner walls of both sides of the slide groove 101, ensuring the linearity and stability of the movement of the slider 102, thereby ensuring the accuracy and reliability of the clamping action.

[0032] Example 4:

[0033] Reference Figure 1 、 Figure 3 , a clamping device for circuit breaker production, which is basically the same as embodiment 1, furthermore, a plurality of groups of heat dissipation grooves 402 are equidistantly provided on the circumference of the mounting cylinder 4, and each group of heat dissipation grooves 402 is provided with a plurality of;

[0034] During operation, the motor 5 generates heat. At this time, multiple groups of heat dissipation slots 402 equidistantly arranged on the circumference of the mounting tube 4 can promote air circulation. At the same time, the heat will be dissipated through the heat dissipation slots 402 along with the air, thereby reducing the internal temperature of the mounting tube 4, ensuring the normal operation of the motor 5, and avoiding damage to the motor 5 due to excessive temperature.

[0035] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
