Abstract

The invention discloses a small and medium-sized plane form grinding machine tool. A vertical shaft upright column is mounted at the rear part of a tool body; a water cooler is mounted behind a water tank; a display is mounted in front of the upper part of an electric cabinet; a grinding head is mounted at the upper end of the vertical shaft upright column; a Y-axis lead screw is mounted inside the vertical shaft upright column; a spindle motor is mounted inside the grinding head; a counter weight is mounted at the rear end of the grinding head; a Y-axis speed reducer matched with the Y-axis lead screw is mounted at the upper part of the grinding head; a Y-axis servo motor matched with the Y-axis speed reducer is mounted at the front end of the Y-axis speed reducer; an abrasive wheel is mounted at the front end of the grinding head; a Z-axis lead screw, a Z-axis servo motor and a Z-axis speed reducer are mounted inside the tool body; according to the grinding head and the vertical shaft upright column of the machine tool, overall vertical movement feeding is realized, and the rigidity and the accuracy stability are high; the grinding capacity of the plane form grinding machine tool is greatly improved, the grinding amount is large, and the accuracy retention is high; the machining stability of a plane grinder is improved. The grinding range of the plane grinder is expanded, and the machine tool is high in accuracy, high in steady mobility and long in service life.

Description

technical field

[0001] The invention relates to the technical field of machine tools, in particular to a medium-sized and small-sized plane forming grinding machine tool. Background technique

[0002] With the industrial upgrading of modern enterprises and the rapid development of aerospace, semiconductor packaging, and new energy technologies, it is required that the five-point grinding flatness, parallelism, and height difference of the surface grinder are all less than 0.002mm, and the profile surface forming grinding accuracy is less than 0.002mm. Surface roughness is less than Ra0.02μm;

[0003] The existing grinding machine structure is fixed on the bed with four bolts on the upper and lower shaft columns. The headstock relies on two flat guide rails with a length of about 200mm and a width of about 20mm to slide up and down on the column, so as to realize the feed of the upper and lower axes. Over time, the guide rail wears quickly and guides, and the accuracy of the...
