Problems solved by technology
[0002] In the process of R&D and production of molded case circuit breakers, the number of opening and closing of products has always been one of the important parameters of its products. The existing detection methods usually use manual measurement and recording data, which is labor-intensive, data accuracy is low, and the detection results are not accurate. Reliable; moreover, there are many types of molded case circuit breakers developed and produced, and the specifications are different. It is difficult for ordinary test devices to meet the detection of molded case circuit breakers of different sizes and different performances.

The invention relates to a mechanical life testing device for molded case circuit breakers. The mechanical life testing device comprises a self-locking lifting mechanism. A molded case circuit breaker can be laid on a laying plate of the self-locking lifting mechanism, a releasing testing mechanism is mounted on the top of the molded case circuit breaker, and a crank and slider mechanism is mounted at an end of the self-locking lifting mechanism. The mechanical life testing device has the advantages that a lead screw of the self-locking lifting mechanism is matched with support arms, so that the test piece laid on the laying plate can be freely lifted to reach a proper position; opening and closing operation on an opening and closing handle can be carried out by a crank connecting rod mechanism of the crank and slider mechanism; a cylinder of the releasing testing mechanism can be pushed, so that a button contact bar can be driven to press a releasing reset button for resetting; the mechanical life testing device is applicable to detecting the mechanical lives of the molded case circuit breakers with different dimensions, full-automatic detection work can be implemented, the molded case circuit breakers can be tested in flat lying or upright states, and the mechanical life testing device is high in efficiency and low in cost.
Description
technical field [0001] The invention relates to the technical field of testing devices, in particular to a testing device for testing the mechanical life of a molded case circuit breaker. Background technique [0002] In the process of R&D and production of molded case circuit breakers, the number of opening and closing of products has always been one of the important parameters of its products. The existing detection methods usually use manual measurement and recording data, which is labor-intensive, data accuracy is low, and the detection results are not accurate. Reliable; moreover, there are many types of molded case circuit breakers developed and produced, and the specifications are different. It is difficult for ordinary test devices to meet the detection of molded case circuit breakers of different sizes and different performances. Contents of the invention [0003] Aiming at the shortcomings of the above-mentioned existing production technology, the applicant provi...
