Description

Technical Field

[0001] The utility model relates to the technical field of mechanical running-in devices, in particular to a mechanical running-in device for a circuit breaker. Background Art

[0002] A circuit breaker is a protective device used in power systems, primarily designed to automatically disconnect the circuit in the event of an overload, short circuit, or other fault, preventing equipment damage, fire, or electrical accidents. It is a crucial electrical protection device widely used in a variety of fields, including household appliances, power distribution, and industrial automation. After assembly, to ensure product quality and reliability, a mechanical run-in test is performed on the circuit breaker. This test measures the mechanical lifespan and mechanical operating capabilities to ensure product quality. This test also optimizes various torque parameters, ensuring smoother and more stable operation during normal operation. This is known as a run-in test, which involves inspecting the circuit breaker's opening and closing.

[0003] Currently, there is no standard mechanical run-in device for circuit breakers. Most factories use simple tools for mechanical run-in, or directly rely on manual operation, or the equipment is relatively rigid and cannot be used flexibly. That is, one device is used for the production and testing of circuit breakers of various models, specifications and sizes, which wastes a lot of manpower, material and financial resources, so improvements are needed. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that circuit breaker production and testing wastes a lot of manpower, material and financial resources, and to propose a mechanical running-in device for circuit breakers.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a mechanical running-in device for a circuit breaker, comprising a workbench, support columns are symmetrically fixedly installed on the bottom of the workbench, a slide groove is penetrated through the top of the workbench, an L-rod is slidably connected inside the slide groove, a connecting plate is fixedly installed on the end of the L-rod away from the slide groove, a telescopic cylinder is fixedly installed inside the connecting plate, a toggle rod is fixedly installed on the output end of the telescopic cylinder, a rack is fixedly installed on the inner side of the L-rod, a mounting plate is fixedly installed on the bottom of the workbench, a first motor is fixedly installed inside the mounting plate, and a gear is fixedly installed on the output end of the first motor.

[0006] Preferably, the gear and the rack are meshed with each other, and the rack and the slide groove are slidably connected.

[0007] Preferably, a limit plate is fixedly mounted on the bottom end of the rack and the L-rod.

[0008] Preferably, a stabilizing block is fixedly mounted on the bottom end of the support column, and the stabilizing block is in the shape of a circular plate.

[0009] Preferably, empty slots are symmetrically opened through the top of the workbench, a second motor is fixedly installed on one side of the workbench, a bidirectional threaded rod is fixedly installed on the output end of the second motor, a sliding plate is symmetrically threaded on the outer wall of the bidirectional threaded rod, and a clamping plate is fixedly installed on the top of the sliding plate.

[0010] Preferably, the sliding plate is slidably connected to the empty slot.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] 1. In the utility model, by starting the first motor, the first motor will drive the gear to rotate when it works. During the rotation process, the gear will drive the rack meshing with it to slide downward inside the slide groove. During the downward sliding process, the rack will drive the L rod to slide downward inside the slide groove. During the downward sliding process, the L rod will drive the connecting plate, the telescopic cylinder and the toggle rod to move downward together. When the toggle rod is moved to be flush with the switch of the circuit breaker, the first motor will be turned off, and then the telescopic cylinder will be started again. When the telescopic cylinder works, it will drive the toggle rod to move. During the movement, the toggle rod will toggle the switch of the circuit breaker. By repeatedly toggling the switch of the circuit breaker, the circuit breaker can be tested for multiple running-in tests. This design realizes the automatic running-in detection function of the circuit breaker, effectively avoids the need for manual operation during the detection process, and improves the running-in detection efficiency of the circuit breaker.

[0013] 2. In the utility model, the circuit breaker to be inspected is placed between the two sets of clamping plates, and the second motor is started after placement. When the second motor is working, it drives the bidirectional threaded rod to rotate. During the rotation process, the bidirectional threaded rod drives the two sets of sliding plates to slide inside the two sets of empty slots toward the position of the circuit breaker. During the sliding process, the two sets of sliding plates drive the two sets of clamping plates to move together. After moving a certain distance, the two sets of clamping plates will clamp and fix the circuit breaker to be inspected. This design greatly improves the fixing effect of the circuit breaker, effectively prevents the circuit breaker from being displaced during the detection process, and improves the stability of circuit breaker detection.

[0022] In this embodiment, by starting the first motor 10, the first motor 10 will drive the gear 11 to rotate when it works. During the rotation process, the gear 11 will drive the rack 8 meshing with it to slide downward inside the slide groove 3. During the downward sliding process, the rack 8 will drive the L rod 4 to slide downward inside the slide groove 3. During the downward sliding process, the L rod 4 will drive the connecting plate 5, the telescopic cylinder 6 and the toggle rod 7 to move downward together. When the toggle rod 7 is moved to be flush with the switch of the circuit breaker, the first motor 10 is turned off, and then the telescopic cylinder 6 is started again. When the telescopic cylinder 6 works, it will drive the toggle rod 7 to move. During the movement, the toggle rod 7 will toggle the switch of the circuit breaker. By repeatedly toggling the switch of the circuit breaker, the circuit breaker can be subjected to multiple running-in tests. This design realizes the automatic running-in detection function of the circuit breaker, effectively avoids the need for manual operation during the detection process, and improves the running-in detection efficiency of the circuit breaker.

[0023] Example 2: Figure 1 As shown, a slot 14 is symmetrically provided on the top of the workbench 1, a second motor 15 is fixedly installed on one side of the workbench 1, a bidirectional threaded rod 16 is fixedly installed on the output end of the second motor 15, a sliding plate 17 is symmetrically threaded on the outer wall of the bidirectional threaded rod 16, a clamping plate 18 is fixedly installed on the top of the sliding plate 17, and the sliding plate 17 is slidably connected to the slot 14.

[0024] In this embodiment, the circuit breaker to be inspected is placed between the two sets of clamping plates 18, and then the second motor 15 is started.

During the rotation process, the bidirectional threaded rod 16 will drive the two groups of sliding plates 17 to slide inside the two groups of empty slots 14 toward the position of the circuit breaker. During the sliding process, the two groups of sliding plates 17 will drive the two groups of clamping plates 18 to move together. After moving a certain distance, the two groups of clamping plates 18 will clamp and fix the circuit breaker to be tested. This design greatly improves the fixing effect of the circuit breaker, effectively prevents the circuit breaker from being displaced during the detection process, and improves the stability of circuit breaker detection. After clamping and fixing, start the first motor 10. When the first motor 10 works, it will drive the gear 11 to rotate.

When the toggle rod 7 is moved to be flush with the switch of the circuit breaker, the first motor 10 is turned off, and then the telescopic cylinder 6 is started again. When the telescopic cylinder 6 works, it will drive the toggle rod 7 to move. During the movement, the toggle rod 7 will toggle the switch of the circuit breaker. By repeatedly toggling the switch of the circuit breaker, the circuit breaker can be subjected to multiple running-in tests. This design realizes the automatic running-in detection function of the circuit breaker, effectively avoids the need for manual operation during the detection process, and improves the running-in detection efficiency of the circuit breaker.
