Problems solved by technology

[0002] In the design of machining fixtures, it often happens that the positioning holes at both ends of the workpiece need to be positioned, but the fixed positioning pins cannot realize the clamping of the workpiece. In addition, the positioning accuracy and stability of ordinary positioning mechanisms are also poor. Therefore, it is necessary to design A mobile positioning pin mechanism to solve such problems conveniently

Abstract

The invention relates to a hydraulic moving expansion sleeve positioning mechanism which comprises a linear sliding rail, a sliding rail installation plate, a fixing seat, an oil cylinder and an expansion sleeve positioning mechanism. The oil cylinder drives the expansion sleeve positioning mechanism to move front and back in a reciprocating manner on the linear sliding rail. The expansion sleevepositioning mechanism comprises an expansion sleeve oil cylinder, a floating pull rod, a taper seat and an expansion sleeve. The expansion sleeve oil cylinder drives the floating pull rod to move. A circular truncated cone is arranged at the front end of the floating pull rod and drives the expansion sleeve to move along the taper face of the taper seat. By means of the hydraulic moving expansionsleeve positioning mechanism, during workpiece clamping, the oil cylinder drives the expansion sleeve positioning mechanism to overall move forwards and retreat backwards through a connecting block toachieve workpiece avoiding, in addition, the expansion sleeve oil cylinder drives the floating pull rod and the expansion sleeve to contract back so that the expansion sleeve can expand in the movingprocess, and the positioning precision and stability of workpiece clamping are improved through design of a positioning expansion workpiece hole.

Description

technical field [0001] The invention relates to the field of fixtures, in particular to a positioning mechanism for hydraulically movable expansion sleeves. Background technique [0002] In the design of machining fixtures, it often happens that the positioning holes at both ends of the workpiece need to be positioned, but the fixed positioning pins cannot realize the clamping of the workpiece. In addition, the positioning accuracy and stability of ordinary positioning mechanisms are also poor. Therefore, it is necessary to design A mobile positioning pin mechanism is provided to solve such problems conveniently. Contents of the invention [0003] Aiming at the problems in the prior art, the present invention provides a positioning mechanism for hydraulically movable expansion sleeves. [0004] In order to solve the above problems, the solution of the present invention is a hydraulically movable expansion sleeve positioning mechanism, including a linear slide rail, a slid...
