Spring grinding machine and grinding method

Abstract

The invention discloses a spring grinding machine and a grinding method. The grinding machine comprises a pedestal, a grinding table, a grinding pool, a grinding body, a first vibration motor and a second vibration motor, wherein the pedestal and the grinding table are both cylindrical; the grinding table is arranged in the center of the top of the pedestal; the diameter of the grinding table is smaller than that of the pedestal; the grinding pool is a drum arranged at the top of the grinding table; a plurality of lower fixing blocks are uniformly arranged at the bottom inside the grinding pool; the grinding body is arranged above the grinding pool; a plurality of upper fixing blocks are uniformly arranged at the bottom of the grinding body; the upper fixing blocks and the lower fixing blocks are in one-to-one correspondence; springs to be machined are placed in the space between the upper fixing blocks and the lower fixing blocks; the grinding pool is filled with a grinding agent submerging the springs; the first vibration motor and the second vibration motor are symmetrically arranged on the two sides of the grinding body; the axes of rotating shafts of the vibration motors are parallel to the axis of the grinding body; the axes of the pedestal, the grinding table, the grinding pool and the grinding body are collinear. The spring grinding machine and the grinding method disclosed by the invention can be used for machining and manufacturing the springs in batches, and has the characteristics of low cost, high efficiency and high quality.

Description

Technical field [0001] The invention relates to a spring grinder and a grinding method, in particular to a spring grinder and a grinding method for processing springs for trains of multiple trains, belonging to the technical field of spring processing. Background technique [0002] Spring is an important functional part in the train vibration reduction system of EMU. Its main function is to absorb and isolate vibration, improve the stability of the vehicle at high speed, ensure the comfort and safety of passengers, and extend the service life of vehicle components and rails. [0003] For a long time, there has always been a technical problem in the processing and manufacturing of springs for EMU trains. For the manufacturers of springs for EMU trains, it is necessary to achieve between the support ring and the effective ring of the spring for the EMU train under the working load. The length of the contact line is greater than one-third of the middle diameter of the spring used in t...

AI Technical Summary

Problems solved by technology

Therefore, the manual grinding process is not only extremely low in production efficiency, it is difficult to achieve large-scale efficient processing and manufacturing, and it is also difficult to ensure that the support ring and the effective ring of the EMU spring after manual grinding must be continuous.

[0005] So far, there is no effective spring processing technology, which can ensure continuous contact between the support ring and the effective ring of the spring used in the EMU, and realize large-scale and efficient production
