Abstract

The invention provides a method for measuring a torsion shaft rolling characteristic parameter by using a laser displacement sensor. The method is conducted on a machine tool and comprises the steps of setting a measuring device; demarcating through a testing bar, and measuring the distance L0 from the axis of the testing bar to a laser head; measuring the distance L' of points on the surface of a torsion shaft to the laser head at each moment, and using an encoder to record the corresponding angle value theta of each measuring point; through R=L0-L' obtaining the distance R of each measuring point of the torsion shaft to the axis of the torsion shaft, and then, storing each theta and corresponding R to (theta, R), and calculating the position of a tooth root of the torsion shaft according to the (theta, R). According to a measuring device established by the method, structure is simple and easy to implement, measuring method is easy to operate, and the requirement to automatic non-contacting measuring to the torsion shaft can be satisfied.

Description

technical field [0001] The invention belongs to the technical field of photoelectric measurement, and relates to a method for measuring characteristic parameters of torsion shaft rolling by using a laser displacement sensor. Background technique [0002] In general, manual contact measurement is commonly used for torque axis measurement, and manual tool setting is also used for tool setting at the tooth root position of the torsion axis. For modern high-efficiency and intelligent processing machines, this obviously does not meet the accuracy requirements and efficiency. Require. Therefore, it is necessary to develop an automated measurement system, which requires automatic non-contact measurement, automatic positioning of the tooth root position, and high measurement accuracy. [0003] There is a method for non-contact measurement of the angle of a workpiece using a laser displacement sensor, but since the torsion shaft is a rotating body, this method is not suitable for th...
