Embodiment Construction

[0021] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] A dynamic compensation method in the press-fitting process of a wheel set, the specific steps are as follows:

[0023] 1) Use the left laser ruler 3, the right laser ruler 4, the left measuring ruler 5 and the right measuring ruler 6 to calculate the theoretical pressing positions of the left wheel 1 and the right wheel 2 to be pressed, see figure 1 shown;

[0024] 2) First press the right wheel 2 and then press the left wheel 1, press one end of the bearing against the reference plane frame 7 through the main pressure head 8, during the press-fitting process, the left wheel 1 remains still, before the right wheel 2 is pressed, the system gives Set a fitting force to press the wheel surface of the right wheel 2 to be pressed. After the system judges that it is tight, the left laser ruler 3 and the right laser ...

Abstract

The invention discloses a dynamic compensation method in a wheel-pair press-fit process. According to the method, a theoretical press-fit position of a left and right wheel to be press-fitted is calculated by a left laser ruler, a right laser ruler, a left ruler and a right ruler; in the press-fit process, a position change value between a left wheel surface and the left laser ruler is calculatedby a system in real time to calculate a left wheel press-fit compensation value and a right wheel press-fit compensation value; and a left wheel press-fit end judgment value and a right wheel press-fit end judgment value are calculated in real time to determine an end bit of the wheel-pair press-fit. The method is simple, and the real-time compensation amount can be calculated according to the real time deformation condition of a rack, so that the precision of the press-fit is greatly improved.

Description

technical field [0001] The invention relates to the technical field of wheel set press-fitting, in particular to a dynamic compensation method in the process of wheel set press-fitting. Background technique [0002] In the prior art, during the press-fitting process of the wheelset by using a press-fitting machine, the press-fitting accuracy may not meet the standard due to the force deformation of the frame. How to solve the above technical problems and ensure the press-fitting accuracy of the equipment is something that those skilled in the art are committed to solving. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a dynamic compensation method in the process of press-fitting wheelsets. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a dynamic compensation method in the process of pressing the wheel set, the specific steps...
