Problems solved by technology

However, this requires regular shutdown and back-to-origin calibration operations, which reduces production efficiency and complicates the operation
[0004] Due to the semi-closed-loop control method and the cumulative error of rotation, it will have a negative impact on positioning accuracy and automated production

Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] see Figure 1-4 , a wheel rotation device, which is applied to the finished product inspection equipment of the wheel inspection line, adopts servo drive control, the servo motor with encoder drives the reduction mechanism and the load shaft, and drives the disc to rotate in one direction in one direction, forming a half Closed loop position control ( figure 1 ). The loading and unloading manipulator of the production line automatically places three w...

Abstract

The invention discloses a wheel rotating device and a positioning detection compensation method thereof, and the method comprises the steps: recording two rotating position values and calculating a deviation value through a positioning detection proximity switch signal and a servo position target arrival signal which are fixed on the ground, building a relation between a motor encoder of a semi-closed loop system and the fixed ground, and carrying out the positioning detection compensation of the wheel rotating device. A full closed loop in a certain sense is achieved, the target position of servo operation every time is adjusted to be step increasing or step decreasing, a window value within allowable positioning precision is set, wall collision type dynamic control is conducted on a deviation value, and position positioning detection and automatic compensation error elimination of a rotating device are achieved.

Description

technical field [0001] The invention belongs to the technical field of automatic control of train wheel detection equipment, and relates to a wheel appearance rotation inspection device for a wheel detection line, in particular to a wheel rotation device and a positioning detection compensation method thereof. Background technique [0002] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0003] With the rapid development of my country's rail transit, the requirements for train wheel inspection and equipment have also been further improved. In the appearance inspection equipment of the newly built train wheel inspection production line, the rotation device is controlled by servo drive. The device automatically places three wheels by the manipulator and rotates them in one direction. Each rotation is 120° at an angle to complete the cycle of loading, inspection, and unloading, realizing aut...
