Grinding tool of inside diameter grinder

Abstract

The invention discloses a grinding tool for an inner diameter muller, which belongs to a muller accessory. The invention includes a rotary grinding carriage fixedly combined on a mandril of a grinding device. The grinding carriage is provided with a grinding wheel welded after being directly inserted which rotates together with the grinding carriage to grind the inner diameter of an object to be machined. The design of the invention prevent the phenomenon of the grinding wheel bending generated when the grinding wheel is combined with the grinding carriage in advance; thereby being able to grind the inner diameter of the object to be machined precisely. Beside, a grinding wheel fixing part of the grinding wheel is made by a sintered body with higher intensity, consequently the invention can prevent the grinding wheel fixing part from bending during a grinding process; thereby achieving further improvement of the machining precision.

Description

technical field [0001] The invention relates to an accessory of a grinder, in particular to a grinding tool for an inner diameter grinder in which a grinding wheel is integrally adhered to a grinding wheel frame in an inner diameter grinder for grinding the inner diameter of a compressor bearing. Background technique [0002] figure 1 It is a schematic diagram of the decomposition structure of the grinding tool of the previous inner diameter grinder; figure 2 It is a partial vertical cross-sectional structural diagram of the grinding tool assembly state of the conventional inner diameter grinder. [0003] As shown in the figure, the grinding tools of the conventional internal diameter grinder include a grinding wheel frame 1 fixedly combined with the spindle of the internal diameter grinding machine and rotating at a constant speed; The outer peripheral surface of the fixed base 2 is welded with a grinding wheel 3 for grinding the inner diameter of a bearing for a compres...

AI Technical Summary

Problems solved by technology

[0007] But, in the above-mentioned grinding tool of internal diameter grinding machine in the past, when screwing in the coupling groove 1b of grinding wheel frame 1 and coupling emery wheel holder 2 screw thread 2a, the phenomenon that coupling protrusion 2a deforms under the action of coupling force often takes place, The grinding wheel 3 is distorted, so the center of the grinding wheel 3 cannot be consistent with the machining center of the workpiece, so there is a disadvantage that the inner diameter of the workpiece is excessively ground, resulting in a poor workpiece

[0008] In addition, the grinding wheel holder 2 and the grinding wheel holder 1 supporting the grinding wheel 3 are made of steel, so the strength is relatively weak. If used for a long time, deformation will occur due to material fatigue. The machining center of the processed product cannot be consistent, and there is also the disadvantage of excessive grinding of the inner diameter of the processed product, which leads to the defect of the processed product
