Specific embodiment
The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of embodiment of the invention, rather than whole embodiments.
Embodiment one
Reference picture 1-2, a kind of refrigerator stamping parts hole position error-proof detection device, with workpiece table to be punched specially on upper module 2
Perforate corresponding position in face offers mounting hole 4, is provided with spring 5 and test pin 3 in mounting hole 4, test pin 3 by spring 5 with
The inwall of mounting hole 4 is abutted, and the position in mounting hole 4 positioned at the top of test pin 3 is additionally provided with microswitch 6, and microswitch 6 is connected with
Jerk circuit, the controllable lathe power-off of jerk circuit is stopped.In actual applications, workpiece to be punched is placed under lathe
On module 1, upper module 2 is moved downward under the drive of power set, if workpiece putting position is correct, test pin 3 enters workpiece
Surface perforate, will not touch microswitch 6, and lathe normally carries out punching press to workpiece；If workpiece putting position mistake, test pin 3
Workpiece surface is touched, and is moved upwards up to touching microswitch 6, and then go out to trigger jerk circuit, lathe is promptly broken
