Method for repairing spindle taper hole through autogenous grinding device

Abstract

The invention discloses a method for repairing a spindle taper hole through an autogenous grinding device, and belongs to the technical field of machine tool maintaining. The method is mainly used forrepairing work of benchmark losses caused by serious numerical control machine tool spindle taper hole damage. The method is suitable for maintaining of the benchmark losses caused by numerical control machine tool spindle taper hole damage. The structure is simple, stability is good, through machine tool feeding, precise control over each time of grinding amount can be achieved, excessive grinding of the spindle taper hole can be avoided, the maintaining cost is greatly reduced, and the spindle taper hole repairing quality is improved. A base, a guide rail bottom plate, a bearing, a rotationshaft, a guide rail, a feeding drag plate, a screw, a screw support and a hand wheel are included, the motor drives a driving belt wheel to rotate, a transmission belt winds around the driving belt wheel and a driven belt wheel, the hand wheel drives the screw to rotate, the guide rail and the feeding drag plate have a fit structure, and relatively axially move, and the method comprises the stepsof using of an autogenous grinder, machine tool precision detection and grinding wheel grinding path performing.

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...

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
