nullThen，When transformator arrives at mechanism for testing 120，Telescopic cylinder 123d drives and pushes slide block 123b along pushing guide rail 123a in cutting agency 130 sliding process，When horizontal plate 1232a moves at stress bearing 122c，Height due to stress bearing 122c peak is higher than the height of horizontal plate 1232a，Therefore horizontal plate 1232a can press down stress bearing 122c to make it the most relatively low，Stress bearing 122c is moved downward along lifting slide unit 122a together by driving lifting slider 122b after downward pressure，Test probe 122d is dropped at transformator transformator is tested，Simultaneously，Transformator is pushed to cutting agency 130 by push unit 123，After propelling movement，Push slide block 123b reversely to reset，When horizontal plate 1232a sails out of stress bearing 122c in reseting procedure，Distress resolves to stress bearing 122c，The spring force that stress bearing 122c sets in passing through under the effect not having external force automatically resets.
Finally, after being completed, time at the rebound 131 that transformator is pushed to cutting agency 130 by push unit 123, proximity switch 125 detects this information and feeds back to controlling organization, controlling organization controls blanking cylinder 135 and starts working, controlling organization according to test result, drives blanking cylinder 135, by push rod 134, transformator pushes certified products chute 132 or defective products chute 133.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that, for the person of ordinary skill of the art, without departing from the inventive concept of the premise, it is also possible to make some deformation and improvement, these broadly fall into protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
