Abstract

The invention provides a large-batch elastic element automatic detection device which comprises a lead screw, the upper portion of the lead screw is fixedly connected to a motor, the bottom of the lead screw is movably connected to a bottom plate of a base, the middle of the lead screw is sleeved with a lead screw nut, the lead screw nut is fixedly connected to an insulating plate, and a circuit board and a plurality of elastic piece contacts are fixedly installed above the insulating plate. The lead screw rotates to drive the circuit board, the insulating plate and the elastic piece contacts to move up and down, the end of each elastic piece contact is electrically communicated with the circuit board, a grating ruler assembly is installed on one side of the insulating plate and used for collecting displacement data of the insulating plate, and an elastic piece installation plate is arranged above the bottom plate and used for fixing elastic pieces. And the motor and the circuit board are connected to an external computer through lines. According to the automatic detection device for the large-batch elastic elements, the consistency and the accuracy of detection references before and after 72-hour pressing are ensured, the detection cost is saved, and the detection efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the field of mechanical product testing, and in particular relates to a testing method for the control of variation before and after a space-same-dimension compression test for a large number of elastic elements. Background technique [0002] Shrapnel production requires that the dimensional change is less than 0.2 after the 72-hour bearing test, which means that the dimensional detection accuracy is required to be less than 0.05. The existing detection methods are divided into two types: 1. The use of image measuring instrument, the image measuring instrument uses an optical microscope to perform high-magnification optical magnification imaging on the object, and through the CCD camera system image, the enlarged object image is input into the computer, and the internal length is calculated. , to detect the contour surface size, angle and position of various complex workpieces. At that time, large-scale detection required analy...
