Description

Automatic testing machine for the elasticity of moving contact spring sheets of refrigeration compressor motor starter protectors

technical field

The invention belongs to the technical field of automatic testing devices for electrical components, and in particular relates to an automatic testing machine for the elasticity of a moving contact spring sheet of a motor starter protector of a refrigeration compressor.

Background technique

The above-mentioned refrigeration compressor motor starter protector is a refrigeration compressor single-phase AC motor overload protector, which provides effective protection for the temperature over-temperature overload of the single-phase AC motor. Its structure can be found in a large number of published Chinese patent documents. Such as CN2218263Y (self-protection refrigeration compressor thermal protector), CN2287339Y (refrigeration compressor motor protector), CN1207743C (thermal protector), CN2341305Y (current temperature composite motor protector) and CN100356652C (single-phase AC motor of overload protectors), etc. Through reading but not limited to the aforementioned patent documents, especially through reading CN100356652C and combining professional common sense, it can be known that when the moving contact on the aforementioned moving contact spring sheet is in contact with the static contact of the pin base, that is, when the moving contact is in contact with When the static contact is closed, the electric circuit is connected, and vice versa, so as to protect the compressor motor, that is, to protect the single-phase AC motor. Specifically, when the radiation of the heating wire or the aluminum cover or the external environment is lower than the induction temperature at which the bimetal is deformed, the bimetal is reset, and the ejector rod is not aligned with the free end of the spring (the aforementioned movable contact is located at the The free end of the spring sheet) generates a force, that is, it does not push the spring sheet. Since the moving contact corresponds to the bottom of the static contact, the moving contact recovers upward under the action of the elastic restoring force of the spring sheet and closes with the static contact. , the motor circuit is turned on. For details, please refer to page 6 of the main text of the specification of CN100356652C.

It can be seen from the above description that the elasticity of the moving contact spring sheet as the structural system of the motor starter protector for refrigeration compressors must meet the technological requirements. The amount of elastic deformation must ensure that the moving contact on it is separated from the static contact on the pin of the starter protector, and when the ejector rod does not push its free end, it must be restored in time to make the moving contact and the static contact Both contact.

Due to the lack of reasonable technical measures in the prior art, there are mainly the following three ways to detect whether the elastic deformation of the above-mentioned movable contact spring sheet meets the requirements: one is to act or release the ejector rod by the artificially preset force, and at the same time, the The online operator observes whether the moving contact on the spring sheet is in contact with or separates from the static contact; the second is that the elasticity of the spring sheet is judged purely by the worker's hand feel; The motor starter protector is connected in a circuit that simulates actual use to verify the elasticity of the movable contact spring. The shortcomings of the first method among the above three methods are: it has greater blindness and subjectivity, because it is difficult or even impossible to scientifically judge with a relatively uniform evaluation standard, and the detection efficiency is low, especially the detection results The sense of responsibility, experience, emotions and work attitudes of the inspectors are different; the second method of the above three methods also varies from person to person as described in the first method above, and even the same person will not The elasticity of the moving contact spring sheets of the same batch yields basically the same results, and even the opposite conclusion is not excluded, and the detection efficiency is also very low; although the third method among the above three methods can draw relatively It is a scientific and reasonable conclusion, but it is impossible to represent all by random inspection, that is, there is a shortage of covering the surface by points, so the limitations are relatively large and the detection cost is high.

In view of the above-mentioned existing technical situation, if there is a mechanical energy that can relatively efficiently and automatically implement a same standard inspection of each movable contact spring sheet without omission, then the above technical problems can be solved, but so far The published Chinese and foreign patents and non-patent documents have not found any technical inspiration that can be used for reference to help solve the above-mentioned technical problems. Therefore, the applicant has made arduous and beneficial repeated designs, and finally formed the technical solution to be introduced below.

The contact spring piece detects the position of the bearing seat 44 and the front pick-up nozzle 77 corresponds to the upper part of the front movable contact spring piece detection bearing seat 44, since the front movable contact spring piece detection bearing seat 44 has been completed at this time. Therefore, in fact, the front pick-up nozzle 77 corresponds to the upper part of the movable contact spring piece 10 . At this time, the front reclaiming nozzle lifting action cylinder 73 works in the opposite direction relative to the above, and the front reclaiming nozzle lifting action cylinder slide block 732 descends to make the front reclaiming nozzle translation action cylinder fixed platform 74 together with the front reclaiming material. The suction nozzle translation cylinder 75 and the front pick-up nozzle 77 descend downward, and the front pick-up nozzle 77 sucks the movable contact spring piece 10 under the action of negative pressure (the reason is the same as the above-mentioned feeding nozzle 35 ). Next, the lifting action cylinder 73 of the front reclaiming nozzle works in the reverse direction, so that the front reclaiming nozzle 77 is displaced upward in the state of sucking the movable contact spring sheet 10, and then the front reclaiming nozzle translation action cylinder 75 Moving in the opposite direction to the previous direction, that is, moving forward, drives the front pick-up nozzle 77 that sucks the movable contact spring sheet 10 to also move forward correspondingly. Then, the horizontal displacement action cylinder 72 of the front reclaiming nozzle acts in the opposite direction to the above, so that the front reclaiming nozzle 77 corresponds to the feeding port 121 of the extraction groove, and at the same time, the front reclaiming nozzle 77 becomes positive pressure. The moving contact spring pieces 10 that have been tested and passed are released to the qualified moving contact spring piece lead-out grooves 12 and introduced into the aforementioned storage box 1421 therefrom. If it is found to be unqualified, the front reclaiming nozzle translation action cylinder 75 will continue to act, so that the front reclaiming nozzle translation action cylinder slider 751 will continue to move forward, so that the previous front reclaiming nozzle 77 corresponds to The position of the inlet 121 of the lead-out groove becomes corresponding to the upper part of the first receiving box I13a of the unqualified movable contact spring piece, and the unqualified movable contact spring piece 10 is released to the first unqualified movable contact spring piece. In the receiving box I13a. so repeatedly.

When the front detection clock thimble 615 of the structural system of the above-mentioned moving contact spring sheet pushes the contact spring sheet head 101 upward, the distance that the moving contact spring sheet head 101 is raised upward is determined by The front detector 92 detects and feeds back a signal to the electrical controller 15. The aforementioned upward raised distance is the degree of elastic deformation of the movable contact spring piece head 101 required by the process, that is, regulated by the quality index. If the upward lift of the movable contact spring piece head 101 meets the requirements, it indicates that the elasticity is qualified, and vice versa. The mechanism of action of the rear detector 94 is as described for the front detector 92 .
