Dimension automatic detection device and method of piston rod

Abstract

The invention relates to a dimension automatic detection device of a piston rod. The automatic detection device comprises a machine body, a feeding mechanism arranged on the machine body, a transmission and detection mechanism, a material distribution mechanism and a blanking mechanism, wherein the feeding mechanism contains an inclined feeding plate, the upper part of the feeding plate is provided with a piston rod leveling pressure plate which is connected with a pneumatic system and can move up and down, the end of the feeding plate is provided with a piston rod block rod which is connected with the pneumatic system and can move up and down; the transmission and detection mechanism contains a power mechanism, a piston rod transmission body, a light source and a camera which are separately arranged on the two ends of the transmission body and an information processing control system connected with the camera; the material distribution mechanism is arranged between the transmission body and the blanking mechanism and contains a rotatable material distribution plate; one end of the material distribution plate is provided with an air cylinder connected with the pneumatic system, the piston of the air cylinder stretches out and retracts to drive the material distribution plate to rotate, the pneumatic system is connected with the information processing control system; and the blanking mechanism contains an upper blanking mechanism and a lower blanking mechanism. The whole structure has delicate design, simple structure, accurate transmission, ultralow error rate, fast detection and high work efficiency.

Description

technical field [0001] The invention relates to a production and processing detection device and method of a piston rod, in particular to a device and a method for comprehensive detection of whether the size of the piston rod meets the requirements. Background technique [0002] Most of the piston rod is used in the cylinder and cylinder movement actuators, which is a moving part with frequent movements and high technical requirements. Whether the various dimensions of the piston rod meet the requirements has a major impact on the production of its subsequent products. Therefore, it is necessary to carry out dimensional inspection on the processed piston rod, and only after passing the test can it enter the next process. Now the detection of piston rod size mainly includes length detection, thread end size detection, and screw riveting end size detection, including overall length, stroke, thread outer diameter, thread bottom diameter, diameter, thread length, thread tilt ang...

AI Technical Summary

Problems solved by technology

At present, domestic piston rod manufacturers mainly adopt manual measurement methods, such as grating rulers, angle gauges and other tools to measure the size of piston rods. This traditional manual visual inspection not only consumes a lot of labor time, but also has very low labor efficiency. More importantly, manual operation errors are large, burying hidden dangers for the quality and safety of final products
