Problems solved by technology

[0013] combine image 3 , the patented device has too much freedom, which will inevitably result in poor structural rigidity and affect the grinding accuracy
Secondly, although NC programming is used to complete the grinding feed at 7:24, it does not give a clear calculation formula for taper and a detailed and reliable grinding process
The accuracy of the final taper repair cannot be accurately detected

Abstract

The invention discloses a method for repairing the taper hole of a main shaft by using a self-grinding device, which belongs to the technical field of machine tool maintenance, and is mainly aimed at the repair work of the loss of the benchmark due to severe damage to the taper hole of the main shaft of a CNC machine tool; Baseline loss repair. The structure is simple and stable, relying on the feed of the machine tool to achieve precise control of the amount of grinding each time, avoiding excessive grinding of the spindle taper hole, greatly reducing maintenance costs, and improving the repair quality of the spindle taper hole; Rotary shaft, guide rail, feed carriage, lead screw, lead screw support, hand wheel; the motor drives the driving pulley to rotate, and the transmission belt bypasses the driving pulley and driven pulley; the hand wheel drives the lead screw to rotate; guide rail and feed carriage It has a matching structure and can move relative to the axial direction. Including the use of autogenous grinding machines, machine tool accuracy testing, and grinding wheel grinding paths.

Description

technical field [0001] The invention belongs to the technical field of machine tool maintenance, and is applicable to a method for repairing datum loss caused by damage to a spindle taper hole of a numerically controlled machine tool by using an self-grinding device. Background technique [0002] Products and methods having the same purpose and similar technical means as the present invention mainly contain the following two types: [0003] Example 1: Patent No.: CN 101829933 A [0004] Name: Machine tool spindle taper hole self-grinding tool [0005] The whole body composed of the longitudinal screw part 6, the grinding head seat 7, the grinding head 9 and the grinding rod 10 is controlled by the handle 19 to feed; Perform feed transmission. [0006] Example 2: Patent No.: CN 106736927 A [0007] Name: A device for self-grinding repair of the taper hole of the spindle of a CNC machine tool [0008] In the present invention, by loosening the locking bolts arranged on th...
