Description

Technical Field

[0001] The utility model belongs to the technical field of gear processing, and particularly relates to a gear center hole polishing and grinding device. Background Technique

[0002] Center holes are usually provided at both ends of shaft parts. When machining shaft parts, they are usually used as the positioning reference of shaft parts. At the same time, they are also the process reference for the clamping, inspection and assembly positioning of shaft parts. Therefore, the accuracy of the center hole directly affects the machining accuracy of shaft parts. After retrieval, the application number is "CN202122120180.5", which discloses "a center hole grinding device for shaft gear machining", which records that "through symmetrically arranged adjusting components, by rotating the adjusting disk, the adjusting rod slides in the sleeve. When the adjusting disk rotates clockwise, the upper limit shell moves away from the lower limit shell, increasing the clamping distance. When the adjusting disk rotates counterclockwise, the upper limit shell moves towards the lower limit shell, shortening the clamping distance, so as to adjust the clamping distance". By using symmetrically arranged adjusting components and rotating the adjusting disk, the adjusting rod slides in the sleeve. When the adjusting disk rotates clockwise, the upper limit shell moves away from the lower limit shell, and the clamping distance does increase.
