Wheel-set pressing-fit machine high-precision control and measurement control system

Abstract

The invention discloses a wheel-set pressing-fit machine high-precision control and measurement control system, which relates to the technical field of pressing-fit machines. The wheel-set pressing-fit machine high-precision control and measurement control system comprises a first grating scale, a left measuring rod, a right measuring rod, a left laser head, a right laser head, a primary stand column, a secondary stand column, a left wheel supporting trolley, a right wheel supporting trolley, a secondary pendulum bob, a primary pendulum bob and a second grating scale, wherein the first grating scale is arranged on one side of the left measuring rod and the right measuring rod, the lower end of the left measuring rod is provided with the left laser head, the lower end of the right measuring rod is provided with the right laser head, and the left measuring rod and the right measuring rod are each connected with a translation hydraulic oil cylinder; the left side of the primary stand column is sequentially provided with the right wheel supporting trolley, the left wheel supporting trolley and the secondary stand column, the secondary stand column is connected with the secondary pendulum bob, and the primary stand column is connected with the primary pendulum bob; and the second grating scale is arranged between the primary stand column and the primary pendulum bob. The wheel-set pressing-fit machine high-precision control and measurement control system does not need system calibration and test before pressing fit, thus a certain amount of errors caused by mechanical deformation amount in traditional pressing fit can be eliminated, thereby greatly improving pressing fit precision of equipment.

Description

technical field [0001] The invention relates to the technical field of press-fitting machines, in particular to a high-precision control measurement control system for wheel-set press-fitting machines. Background technique [0002] The method generally used in the existing wheel set press machine measurement control press-fit technology system is: a group of hydraulic cylinders drive a group of two measuring rods installed and fixed on a back plate to move the overall measuring structure, and the measuring rods fit together to be pressed. On the inner side of the wheel-to-wheel disc, when the press-fitting work starts, the press-fitting cylinder pushes the wheel disc to press-fit, and the movement of the wheel disc drives the movement of the measuring rod. By monitoring the moving distance of the measuring rod, combined with the measured data such as the length of the wheel-to-axle Judge the pressing stroke. [0003] In the existing wheel set pressing machine measurement co...

AI Technical Summary

Problems solved by technology

[0003] In the existing wheel set pressing machine measurement control pressing technology, due to the direct contact between the measuring rod and the wheel disc during the measurement process, the force will produce a certain amount of mechanical deformation during the pressing process, which will affect the accuracy error of the moving distance of the measuring rod , and the whole main machine will have a certain amount of mechanical deformation with the change of the press-fitting force during the press-fitting process, which will affect the accuracy of measurement and press-fitting data
