Problems solved by technology

However, this method can only measure the radial runout value, cannot determine the direction of the runout, and cannot measure the runout of the end face, so the practical application is of little significance

Embodiment 1

[0015] A coiler in a cold-rolled thin plate factory had a phenomenon of strip deviation during high-speed coiling, which affected product quality. In order to find out the cause, radial runout detection was carried out on the coiler at different speeds. The common method is to use the dial indicator to detect, but the high linear speed when the coiler rotates is unbearable to the dial indicator, and the dial indicator will fly when it is close to 400 revolutions, so the method of the present invention is used to Fix the target at the end of the coiler support, and then use the dynamic detection function of the laser dynamic tracker to collect data. According to user requirements, the radial runout of the coiler is collected at 100 rpm, 300 rpm, 400 rpm, 600 rpm, and 800 rpm. Processing analysis solves this detection problem.

Embodiment 2

[0017] The sparking phenomenon was found in the V3 motor in the rough rolling mill, and the axial movement of the motor shaft was required to be detected. Using the method of the present invention, the target was fixed on the end face of the motor shaft with tooling, and the dynamic detection function of the laser dynamic tracker was used for data collection. The data acquisition process is divided into: 1. 20% speed; 2. 40% speed; 3. 60% speed; 4. 80% speed; 5. 90% speed; 6. 50%--90%--50% speed; 7. 0--80%--0 speed, use the tracking function of the instrument to record data, use the coordinate reconstruction function of the operating system to process the data, and draw a graph such as figure 2 The axial movement can be obtained from the movement amplitude diagram of the blooming mill.

Abstract

The invention discloses a lossless detecting method of axle element, which is characterized by the following: detecting the working state end-face and radial tripping quantity through laser dynamic tracking method; fixing the reflecting light target on the operational axle element through carpenter; gaining the tripping value and direction of axle element through reflecting light target mobile data of laser dynamic tracker; gathering the dynamic three-dimensional data in the working condition; disposing the data; gaining the tripping amplitude and frequency of axle element in the rotary algorithm condition. The invention can analyze the tripping value and direction of axle element in the moving condition.

Description

Technical field [0001] The invention discloses a method for detecting the working state end face and radial runout of a shaft component, which relates to a non-destructive detection method for the shaft component. Background technique [0002] In mechanical transmission, the runout value of shaft parts is somewhat high. Excessive runout of shaft parts will not only increase the loss of equipment such as shafts, bearings, electrodes, etc., generate huge noise, cause equipment accidents, but also reduce the operation of equipment. Accuracy affects the quality of the product. Therefore, shaft parts have strict requirements on the control of runout (end face runout, radial runout) during processing. Even so, during the operation of many equipment, due to installation, wear, partial load and other reasons, there are considerable jumps in the shaft parts, which affect the normal use of the equipment. Therefore, measuring the runout (end face runout, radial runout) of shaft parts...
