Further optionally, the third jaw 110c includes two opposite clamping plates 111 and a clamping drive mechanism 115 for driving the two clamping plates 111 to approach or separate from each other; wherein, the clamping plates 111 are made of insulating materials, and conductive contact blocks 112 are provided on the lower parts of the opposite sides of the two clamping plates 111;

[0051] Specifically, the automatic wiring tooling for circuit breakers provided in the embodiments of the present application is applicable to automatically wiring ZW32 and ZW20 type circuit breakers. During the use process, due to the differences in the sizes of the circuit breakers, the first orientation adjustment mechanism 120 and the second orientation adjustment mechanism are used to adjust the orientations of the jaws (the first jaw 110a, the second jaw 110b, and the third jaw 110c) of the clamping mechanisms (the first clamping mechanism 110, the second clamping mechanism 210, and the third clamping mechanism 220), so as to accurately position them, and the conductive contact blocks 112 of the two clamping plates 111 of the jaws are made to approach each other to clamp the contacts of the circuit breaker;

[0052] Among them, the two clamping plates 111 of the clamping jaws (the first clamping jaw 110a, the second clamping jaw 110b, and the third clamping jaw 110c) are made of insulating materials, and the conductive contact blocks 112 are made of conductive materials for external connection of wires (including but not limited to copper blocks, etc.). When the conductive contact blocks 112 automatically clamp the contacts of the circuit breaker, through the cooperation of the conductive contact blocks 112 and the external wires on the conductive contact blocks 112, automatic wiring of the contacts of the circuit breaker is achieved. In addition to the conductive contacts and the external wires, the clamping plates 111 are made of insulating materials, which can prevent the circuit breaker from forming a circuit connection with other components, so as to test the circuit breaker.

[0053] In the embodiment of the present application, the orientation of the clamping jaws of the clamping mechanism is adjusted by the orientation adjustment mechanism (the first orientation adjustment mechanism 120, the second orientation adjustment mechanism), so that the clamping mechanism can smoothly reach the required position, and the clamping jaws cooperate to drive the conductive contact blocks 112 on the two clamping plates 111 to automatically clamp the contacts of the circuit breaker, thereby realizing automatic wiring of the contacts of the circuit breaker to test the circuit breaker. During the test process, using the clamping jaws to clamp the contacts can make the wiring firm, the electrical contact of the wiring good, and the conductive circuit clear, which can meet the requirements of circuit breaker maintenance. This tooling is applied to actual maintenance, which can save a lot of manpower, improve the maintenance efficiency and the quality of the detection results.

[0054] It should be noted that:

[0055] In the embodiment of the present application, the clamping jaws used are pneumatic jaws, that is, the clamping drive mechanism 115 that drives the two clamping plates 111 to approach or separate is a cylinder. The working principle that the cylinder can drive the two clamping plates 111 to approach or separate through the structural and constructional design is prior art and will not be elaborated here. The design concept of the present application lies in designing the insulating clamping plates 111 and the conductive contact blocks 112 in the clamping jaws. Therefore, for how to realize the driving mechanism in the clamping jaws to drive the clamping plates 111 to clamp or release, those skilled in the art can select from the existing clamping jaws with automatic driving and clamping, including but not limited to selecting pneumatic jaws.

[0056] Optionally, the first orientation adjustment mechanism 120 includes a frame 122 and a first driving component 121 fixedly connected to the top of the machine frame 30; a plurality of first clamping mechanisms 110 are fixedly connected to the bottom surface of the frame 122; the output end of the first driving component 121 is fixedly connected to the top of the frame 122 and is used to drive the frame 122 to move up and down so as to drive the first clamping mechanism 110 to move up and down.

[0057] During use, the output end of the first driving component 121 drives the frame 122 to move up and down, thereby driving the first clamping mechanism 110 to move up and down. In addition, through the design of the fixing plate 123 and the guide post 124, during use, the output end of the first driving component 121 applies a force to the frame 122 to drive it to move up and down, so that the guide post 124 slides up and down in the linear bearing 1231 of the fixing plate 123. Through such a design, the entire plane of the frame 122 moves up and down more stably, avoiding the frame 122 from shaking or tilting in the front, back, left, and right directions.

[0059] By designing the spring floating mechanism 113 in the first clamping mechanism 110 and the elastic block 114 in the second clamping mechanism 210 and the third clamping mechanism 220, when the first clamping mechanism 110, the second clamping mechanism 210 and the third clamping mechanism 220 are driven to the breaker contact positioning area for clamping, a certain buffering effect is achieved when contacting the breaker, avoiding the occurrence of severe collision damage when the breaker contacts the clamping mechanism;

[0060] In addition, the spring floating mechanism 113 of the first clamping mechanism 110, the elastic block 114 of the second clamping mechanism 210 and the third clamping mechanism 220 are designed with insulating materials, further avoiding the formation of electrical circuit connection between the breaker and other components except for the conductive contact and the external wire path, so as to test the breaker.

[0064] During use, the specific operation process of the whole machine during the operation of the second orientation adjustment mechanism is as follows:

[0065] The operation process of the whole machine propulsion mechanism 230 is as follows: the output end of the second driving component 231 is fixedly connected to the main board 232, so that the second driving component 231 drives the first X-axis slider 234 of the main board 232 to slide back and forth on the first X-axis guide rail 233, causing the main board 232 to slide back and forth to drive the entire three-direction movement mechanism combination thereon (including the first carrier plate 242, the second carrier plate 252, the third carrier plate 262, and the second clamping mechanism 210) and the third clamping mechanism 220 to move back and forth;
