Problems solved by technology

[0002] In the grinding head assembly of the existing vertical high-speed grinding machine, the lifting drive assembly of the rotating spindle of the machine head is often arranged along the axial direction of the rotating spindle, and adopts a built-in structure, that is, the rotating spindle is pushed and pulled to achieve lifting. This kind of structure makes the processing of each part in the grinding head assembly difficult, the processing accuracy is difficult to guarantee, the overall assembly is more complicated, the subsequent maintenance is inconvenient, and the maintenance cost is high

Abstract

The invention relates to an intelligent double-sided grinding head assembly of a vertical high-precision high-speed grinding machine. The intelligent double-sided grinding head assembly comprises a machine head sleeve, a main shaft rotating core shaft sleeve, a main shaft rotating core shaft, a V belt wheel core shaft fixing sleeve and a V belt wheel core shaft, wherein the V belt wheel core shaft is positioned on the periphery of the main shaft rotating core shaft; a square window is formed in the machine head sleeve; a screw rod nut seat which is fixedly connected with the outer wall of the main shaft rotating core shaft sleeve and penetrates through the square window is mounted at the square window; a screw rod nut and a longitudinal ball screw matched with the screw rod nut are arranged on the screw rod nut seat; and a lifting reducer and a servo motor are mounted at one end of the longitudinal ball screw. According to the intelligent double-sided grinding head assembly, a grinding head main shaft lifting driving component and a grinding head main shaft rotating driving component are mutually independent, the lifting driving component is oppositely positioned at the side part of a main shaft, and an externally arranged structure is adopted, so that the assembly, control and maintenance are more convenient, the changeability of parts is high, the entire machine cost and maintenance cost and are greatly reduced, and the service life is greatly prolonged.

Description

Technical field: [0001] The invention relates to the technical field of processing machine tools, in particular to a grinding head assembly of an intelligent double-sided vertical high-precision high-speed grinding machine. Background technique: [0002] In the grinding head assembly of the existing vertical high-speed grinding machine, the lifting drive assembly of the rotating spindle of the machine head is often arranged along the axial direction of the rotating spindle, and adopts a built-in structure, that is, the rotating spindle is pushed and pulled to achieve lifting. This kind of structure makes it difficult to process each part in the grinding head assembly, and it is difficult to guarantee the processing accuracy. The overall assembly is relatively complicated, and the subsequent maintenance is inconvenient and the maintenance cost is high. Invention content: [0003] The object of the present invention is to overcome the above-mentioned shortcomings of the prio...
