Internal thread passage detection equipment

Abstract

The invention relates to internal thread passage detection equipment which comprises a rack, a feeding device, a positioning sliding table and a detection mechanism. The feeding device comprises a vibration disk, a manifold block, a segmentation block, a feeding hose and a feeding cylinder; the detection mechanism comprises a bracket, a hold-down driving part, a rotation motor and a through-end not-go-end gauge; the bracket is mounted on the bracket; the hold-down driving part is arranged on the bracket; the rotation motor is mounted on the hold-down driving part; the through-end not-go-end gauge is arranged on an output shaft of the rotation motor; the hold-down driving part is used for pushing the through-end not-go-end gauge to vertically ascend or descend along the outer sidewall of the bracket; and the rotation motor is used for driving the through-end not-go-end gauge to rotate. To-be-detected workpieces are stored in the feeding device, the feeding device automatically transmitsthe to-be-detected workpieces onto the positioning sliding table one by one, the positioning sliding table carries out clamping positioning on the to-be-detected workpieces, and the through-end not-go-end gauge is driven by the motor to detect the to-be-detected workpieces, so that force application consistency when the workpieces are detected each time is ensured, a detection error caused by anexternal force is avoided, and detection efficiency is improved.

Description

technical field [0001] The invention relates to the field of automatic detection, in particular to a device for detecting the passage of internal teeth. Background technique [0002] The go-no-go gauge is a kind of measuring tool. In actual production, it is very troublesome to measure a large number of products one by one with measuring tools (such as vernier calipers, dial gauges, etc.). Qualified products have a measurement range. All within this range are qualified, so people use the pass gauge and the stop gauge to measure. [0003] However, the force applied when using the go-no-go gauge to detect products is an important factor affecting the detection accuracy of the go-no-go gauge. If the applied force is too small, the go-no-go gauge cannot enter the product under test, and the processed size of the product under test is misjudged to be too small. , On the contrary, if the force is too large, the stop gauge will enter the product under test, the defective product w...
