Abstract

The invention relates to the field of lead screw detection, in particular to a lead screw lead accuracy detection device. The lead screw lead accuracy detection device comprises a mechanical portion, a movement control portion, a data collection portion and a computer. The mechanical portion comprises an instrument main frame, a detection rail, a linear grating ruler, a circular grating pair and a detection head device. The movement control portion comprises a motor, a motor driver and a movement control card. The data collection portion comprises a data collection card and a signal transferring board. Detection software is arranged on the computer, the computer is connected with the movement control card and the data collection card through a data bus, and the computer controls the motor in real time, conducts data collection of grating signals of the circular grating pair and grating signals of the linear grating ruler in real time, and displays a result and an error curve after conducting processing through the algorithm in the detection software. The lead screw lead accuracy detection device is used for detecting the accuracy of the lead of a lead screw.

Description

technical field [0001] The invention relates to the field of screw rod detection, in particular to a detection device for the accuracy of the lead of a screw rod. Background technique [0002] Ball screw is a high-precision and high-efficiency transmission mechanism, which is widely used in CNC machine tools, automobiles, aviation and other manufacturing industries. It is one of the transmission and positioning components widely used in modern machinery. With the development of my country's industry, the output of ball screws continues to increase, and the demand for high-precision screws expands, and the requirements for the accuracy of ball screws (mainly for the detection of lead accuracy) are also getting higher and higher. . At present, small and medium-sized enterprises still rely on manual measurement of workers to solve the detection problem. Such a detection method is not only inefficient but also poor in accuracy. There are also high-precision testing equipment f...
