A Centrally Positionable Chuck Mechanism for Inner Hole Straight Grinders

Abstract

The invention relates to the technical field of mechanical processing and assembly, and discloses a center-positionable inner hole straight grinder chuck mechanism, which includes a positioning sleeve, a clamping link is fixedly installed on the right side of the outside of the positioning sleeve, and the positioning sleeve One side of the inside is provided with an adjustment cavity, and one side of the inside of the adjustment cavity is movably connected with an adjustment sleeve, and the inside of the adjustment sleeve is threaded with an adjustment screw, and one end of the adjustment screw runs through and extends to the inside of the positioning sleeve And it is connected with the piston on the inner wall of the positioning sleeve through the pressure ball. The chuck mechanism of the inner hole straight grinder that can be centered can store energy on the pressure ball in advance by adjusting the setting of the sleeve, the adjustment screw and the pressure ball, so as to pre-adjust the grinding depth of the grinding wheel, which is different from the existing straight grinder. Compared with the grinding machine, it is not necessary to adjust the grinding depth while grinding artificially, and at the same time, the force between the three sets of grinding wheels is equal, which further improves the grinding accuracy of the chuck mechanism.

Description

technical field [0001] The invention relates to the technical field of mechanical processing and assembly, in particular to a centrally positioned inner hole straight grinder chuck mechanism. Background technique [0002] Mechanical assembly is a labor process in which several parts or components are combined and spliced ​​into a complete product according to the specified technical requirements. In the process of assembly, the cooperation between shaft parts and holes is a common assembly structure, but the processing of inner holes is due to Due to factors such as processing conditions, materials and external temperature environment, there will be a certain accuracy error in the inner hole structure after processing, which will cause the shaft parts to fail to meet the assembly requirements. [0003] Therefore, in the process of assembly work, straight grinders are often used to grind the inner holes to a certain extent, but the existing straight grinders cannot effectivel...

Problems solved by technology

[0005] The present invention provides a centrally positioned inner hole straight grinder chuck mechanism, which has the advantages of good uniformity and coaxiality of the hole wall after grinding, high grinding accuracy, easy adjustment, and convenient operation, and solves the problem of In the process of grinding the inner hole of the existing straight grinder, the center cannot be effectively positioned, and the assembly personnel can only rely on the hand-held straight grinder to tighten the hole wall and carry out the grinding operation, which is difficult to control, and this kind of grinding The method belongs to a segmented grinding, which makes it impossible to accurately control the grinding depth of the inner hole, which eventually leads to poor uniformity and coaxiality of the hole wall after grinding, and poor grinding accuracy.
