A positioning and clamping device for a boss bush

Abstract

The invention provides a positioning clamping device for a boss bushing, and belongs to the technical field of mechanical equipment. The positioning clamping device comprises a disc, clamping support columns, a sliding column, centering column pins, positioning baffle blocks and a post rod, wherein the disc is mounted on a hemisphere head support base; the clamping support columns are vertically mounted on the disc; the post rod is arranged on the fixing support base in a manner of sliding up and down; the lower end of the post rod is connected with the hemisphere head support base; the sliding column is coaxially mounted on the post rod; three driving inclined surfaces are arranged on the sliding column at equal angles; three sliding groove holes are formed in the fixing support base at equal angles; the centering column pins are arranged on sliding sleeves in a sliding manner; one end of each centering column pin is a driven inclined surface; the driven inclined surfaces are adhered to the driving inclined surfaces; the boss busing is mounted on a platform support base; a vertical support column guide groove is formed in the platform support base; the vertical support column guide groove is formed right above the clamping support columns; the positioning baffle blocks are inverted L-shaped and are mounted on outer sides of the circumference of the platform support base. The positioning clamping device is capable of positioning and clamping the boss bushing and is reasonable in structure and good in reliability.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a positioning and clamping device for a boss bush. Background technique [0002] A bushing is a ring that acts as a pad. In the moving parts, the wear of the parts is caused by long-term friction. When the gap between the shaft and the hole is worn to a certain extent, the parts must be replaced. Therefore, materials with lower hardness and better wear resistance are selected as the bushing or bushing. sleeve, which can reduce the wear of the shaft and seat. When the shaft sleeve or bush is worn to a certain extent, replace it, which can save the cost of replacing the shaft or seat. Generally speaking, the bush and seat adopt interference fit, and the The shaft adopts clearance fit, because wear and tear cannot be avoided no matter what, and it can only prolong the life, while shaft parts are relatively easy to process. The shaft sleeve is used to replace the rolli...
