Speed reducer worm diameter and length automatic detection device and method

Abstract

The invention discloses a speed reducer worm diameter and length automatic detection device and method. The device comprises an upper computer module, a driving module, a connecting module, a diameterautomatic detection module, a length automatic detection module, a measured piece clamping module, a supporting module and a limiting module. In the detection process, displacement of a left measuring head and a right measuring head is measured through a grating ruler, and the diameter of a measured shaft section of the speed reducer worm is calculated in combination with the initial distance ofthe two measuring heads; the starting position and the ending position of the measured shaft section of the speed reducer worm are obtained through the grating ruler and a laser displacement sensor, and then the length of the measured worm shaft section is obtained through calculation. The speed reducer worm diameter and length automatic detection device and method can adapt to batch detection ofthe diameters and the lengths of different shaft sections of the speed reducer worms of various specifications.

Description

technical field [0001] The invention relates to a batch automatic detection device and method for a reducer worm aiming at known design parameters, in particular to an automatic detection device and a method for automatic detection of diameters and lengths of different shaft sections of a reducer worm. Background technique [0002] With the rapid development of my country's machinery industry, the requirements for machining accuracy of mechanical parts are getting higher and higher. Shaft parts have the functions of transmitting torque, supporting and fixing other parts, so they are widely used in various mechanical devices. The reducer is a transmission device widely used to transmit torque and change speed between the prime mover and the working machine. Improving the precision of the drive worm of the reducer is conducive to improving the reliability, stability, transmission efficiency and accuracy of the equipment, and reducing assembly errors and vibration and noise du...

Problems solved by technology

[0003] At present, the detection of the diameter and length of different shaft sections of the reducer worm mainly relies on manual caliper detection and manual recording of diameter and length data, which has many problems such as large detection errors, low work efficiency, and high labor costs; some manufacturers use The linear inductive displacement sensor detects the diameters of different shaft sections of the worm of the reducer. When in use, it is necessary to manually adjust the initial position of the inductive displacement sensor for different types of worms with different diameters. The adjustment is cumbersome and time-consuming, and it is inconvenient to use. Multi-batch worms for mass inspection

[0004] To sum up, at present, the detection of the diameter and length of the worm of the reducer is still mainly performed by manual operation, and there is a lack of related devices that can be automatically detected, easy to operate, and can simultaneously detect the diameter and length of the shaft section
