Cylindrical pin length detection device and detection method thereof

Abstract

The invention discloses a cylindrical pin length detection device and a detection method thereof. Before detection, after air pressure of a fixed numerical value is given, the pressure readings of cylindrical pins with a standard length during contact with a pressure sensor are certain interval value, and when the pressure readings of the pins driven by a third air pressure rod after contacting the pressure sensor are not within the interval value, the detection result is unqualified, the operation is convenient, and the detection result is accurate; meanwhile, by driving a horizontal moving part and a vertical moving part, clamping parts can be driven to move, by driving a second air cylinder, a second air pressure rod drives a second connecting block to move downwards, clamping blocks get close to each other to clamp the cylindrical pins, and then the detected cylindrical pins are placed in a sliding way or a placement box according to the detection result, meanwhile, to-be-detectedcylindrical pins are placed in a placement groove at a side end of a third air cylinder, in the detection process, only manual discharging is needed, the operation is convenient, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the detection field of pins, in particular to a cylindrical pin length detection device and a detection method thereof. Background technique [0002] The pin is one of the commonly used mechanical standard rooms. The main function of the pin is to fix the relative position of two parts. A generally cylindrical part of wood, metal, or other material, especially a support used to hold several separate objects together or to suspend one object from another. It is one of the commonly used fasteners in modern mechanical equipment. The diameter and length of the cylindrical surface are an important data to distinguish its specifications. [0003] Most of the existing pin detection devices are to detect its diameter, and the detection device of the length is relatively rare. Most of the existing length detection methods use vernier calipers and other instruments to measure, which has high detection accuracy and can eliminate pins th...

AI Technical Summary

Problems solved by technology

Most of the existing length detections are measured by vernier calipers and other instruments. The detection accuracy is high, and the pins that deviate from the standard length tolerance can be eliminated. However, there is a problem of low efficiency when measuring manually.

When a large number of pins need to be tested for length, manual operation will reduce the detection efficiency, and long-term work will also cause errors. Once the qualified products are mixed with unqualified products, it will easily cause the danger of subsequent production and cause damage to production equipment.
