Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cylindrical grinding machines, and particularly relates to a rough grinding feeding mechanism of a cylindrical grinding machine. BACKGROUND

[0002] In the processing of a cylindrical grinding machine, the rough grinding process is a key link. The main purpose of rough grinding is to quickly remove the large excess of the workpiece, to lay a good foundation for the subsequent fine grinding process, so as to improve the overall processing efficiency and ensure the final processing quality. In the rough grinding stage, the stability, accuracy and reasonable control of the feeding speed of the feeding have a crucial influence on the processing effect.

[0003] On the one hand, stable and uniform feeding can ensure that the workpiece enters the grinding area at a suitable speed and posture, so that the relative stable contact state between the grinding wheel and the workpiece is maintained, and the quality problems such as surface burn, size precision out-of-tolerance and shape error of the workpiece are avoided due to the fluctuation of the feeding. For example, if the feeding speed is too fast, the grinding load of the grinding wheel is too large at a moment, which can easily cause the surface roughness of the workpiece to be poor, and even the grinding wheel can be prematurely worn and damaged; and if the feeding speed is too slow, the processing efficiency will be reduced and the production cost will be increased.

[0004] On the other hand, different sizes, shapes and materials of workpieces often require different feeding parameters during rough grinding, and the feeding mechanism is required to have a certain universality and adjustability to adapt to diversified processing tasks. At the same time, accurate feeding positioning is also one of the key factors to ensure the grinding accuracy of the workpiece, which needs to ensure that the workpiece can accurately enter the preset grinding position, otherwise it may cause uneven distribution of the processing allowance, affecting the allowance removal of the subsequent fine grinding process and the size accuracy of the final product.

[0005] The conventional rough grinding feeding mechanism of the cylindrical grinding machine mostly adopts a simple mechanical transmission structure, such as a gear, a screw nut and the like transmission mode to realize the feeding action of the workpiece. However, these mechanical transmission parts will gradually decrease the transmission accuracy due to the problems of wear, clearance and the like during long-term use, and it is difficult to accurately control the feeding speed. For example, after the screw nut pair is used for a period of time, the fitting clearance between the screw and the nut is increased, so that the workpiece will appear the phenomenon of uneven speed during feeding, which cannot meet the requirement of the stability of the feeding speed for high-precision rough grinding processing. Therefore, in order to solve the above problems, the present application provides a rough grinding feeding mechanism of a cylindrical grinding machine. CONTENT OF THE INVENTION
