Problems solved by technology

From the actual repair effect, this structural device often cannot achieve the expected repair accuracy of the spindle taper. This is because the machine tool spindle taper hole itself has been severely worn, and it is obviously impossible to use the poor spindle taper hole as a reference for grinding. Achieving the desired accuracy requirements

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Such as figure 1 , figure 2 and image 3 As shown, the machine tool spindle taper hole repairing device in the present invention includes a base 1, the bottom surface of the base 1 is a horizontal positioning surface, and the top of the base 1 has an inclined surface that is compatible with the taper of the machine tool spindle taper hole 20. A sliding guide rail 7 is fixedly installed on the top, and the axis of the sliding guide rail 7 is arranged along the inclination direction of the inclined plane. A driving mechanism for reciprocating motion, a grinding device is fixedly installed on the workbench 5, and the grinding device includes a drive motor 3, a grinding spindle 6 and a grinding wheel rod 8, and the shell of the grinding spindle 6 and the drive motor 3 are fixedly installed on the workbench 5, the input end of the rotating main sh...

Abstract

The invention relates to a machine tool spindle taper hole repair device and a machine tool spindle taper hole repair method, and belongs to the technical field of repairing of a machine tool. In therepairing process, the machine tool is started to rotate a spindle of the machine tool; secondly, a driving motor of a grinding device is started, a grinding wheel rod rotates around its own axis, then the grinding wheel rod is driven to move and feed in the axial direction of the grinding wheel rod through a driving mechanism of a workbench, and the repairing of a spindle taper hole of the machine tool is completed through the above three composite motions. By adopting the repairing mode, the repairing precision is mainly ensured by the horizontal precision of the bottom surface and the taperprecision of the upper inclined surface in the manufacturing and machining process of a base, so that the phenomenon that the spindle taper hole with serious abrasion is used as a reference is avoided, the spindle taper repairing precision effect can be effectively guaranteed to reach the expected requirement, and installation and implementation are convenient.

Description

technical field [0001] The invention relates to a device for repairing a taper hole of a machine tool spindle, and at the same time relates to a method for repairing a taper hole of a machine tool spindle, belonging to the technical field of machine tool repair. Background technique [0002] During the machining process of automobile panel mould, the cutting impact vibration caused by unreasonable cutting force or workpiece material defects is easy to cause the wear of the taper hole of the machine tool spindle. The out-of-tolerance of axial and axial runout has a great impact on the machining accuracy of the mold, so the taper repair of the spindle has become an important item in the daily maintenance of machine tool accuracy. In view of the above situation, in the current mainstream machining enterprises, a method After dismantling the spindle and taper shank, perform grinding on special equipment, and reinstall the machine tool after eliminating the abnormal wear of the t...
