High-precision portable inner taper hole grinding device

Abstract

The invention discloses a high-precision portable inner taper hole grinding device. The grinding device comprises a base, a lower supporting plate arranged on the base through a center shaft, a feeding motor arranged on the lower supporting plate, an electric main shaft arranged on an upper supporting plate and a grinding head arranged on the electric main shaft, wherein the upper supporting plate slides on a sliding rail arranged on the lower supporting plate through lead screw transmission, and the lead screw and the feeding motor are in transmission through a belt. According to the scheme, the angle of the portable inner taper hole grinding device can be adjusted in a stepless mode, the compatibility of the grinding device is improved, the application range is enlarged, grinding of an inner taper hole of the main shaft can be completed without disassembling a machine tool main shaft, and the repairing efficiency is greatly improved; the electric main shaft for the grinding machine is selected as grinding power, so that the machining efficiency and the machining precision are improved; the semi-open type box body base enables the portability of the whole device to be greatly improved; and according to the scheme, the problems that in the grinding process of the inner taper hole of the large machine tool main shaft, the main shaft is difficult to disassemble, the inner taper hole grinding workload is large, and the grinding precision is not high are solved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a high-precision portable inner taper hole grinding device. Background technique [0002] The precision and roughness of the inner taper hole of the spindle are strictly required. How to ensure the tight fit between the inner taper hole of the machine tool spindle and the tool holder is the key; it is difficult to disassemble the main shaft of a large machine tool, and the grinding workload of the inner taper hole is heavy. Therefore, under the existing conditions, how to ensure the precision and roughness of the inner taper hole, quickly grind the inner taper hole of the spindle, reduce the workload, and improve work efficiency are difficult points. [0003] Electric spindle is a high-tech of CNC machine tools. With the rapid development of CNC technology and cutting tools, more and more mechanical equipment is developing towards high speed, high precision, high efficiency,...
