Locating pin size screening machine

Abstract

The invention provides a positioning pin size screening machine, comprising a base, the base is provided with a first slide rail facing forward and backward, a first slide table is installed on the first slide rail, and one side of the first slide rail is fixed There is a first drive device, a second slide rail is installed on the first slide rail, a second drive device is fixed on one end of the second slide rail, and a second slide table is installed on the second slide rail, so A limiting plate is installed on the second sliding table, and the limiting plate is provided with a limiting hole for placing positioning pins, and a limiting height plate is arranged above the limiting plate, and a height limiting plate is provided on the limiting plate. Through the through hole of the positioning pin, a sensor is provided at the end of the height limiting plate, the sensor is connected to the signal receiver, and a feeler rod is provided at the position corresponding to the sensor at the end of the limiting plate. The locating pin size screening machine provided by the present invention can automatically prompt the locating pins whose length is unqualified.

Description

technical field [0001] The invention relates to a positioning pin size screening machine, which belongs to the field of manufacturing equipment. Background technique [0002] Locating pins have certain applications in some mechanical movement equipment, mainly for position determination based on two-dimensional space. It is the most widely used in the mold, mainly in the mold composed of two or more parts, the pin designed to make the adjacent two parts of the mold accurately positioned. Molds include stamping molds, injection molds, etc. Their precision requirements are particularly high, and it is definitely not possible to fix the formwork only by bolts, so only positioning pins can be used to achieve the purpose of positioning, or to prevent installation. , wrong direction, etc. [0003] The mold has strict requirements on the dimensional precision of the locating pins, but the current locating pin size screening machines generally have complex structures, high cost, h...

AI Technical Summary

Problems solved by technology

[0003] The mold has strict requirements on the dimensional precision of the locating pins, but the current locating pin size screening machines generally have complex structures, high cost, high failure rate, or need to use measuring tools to measure, which is prone to human error, and the detection of unqualified The positioning pin has no automatic alarm function and other problems
