Fixture for box body with cylinder type structure

Abstract

The invention discloses a fixture for a box body with a cylinder type structure. The fixture for the box body with the cylinder type structure solves the problems that a box body is easy to deform to lead to being seriously overproof at the positions of a bearing hole and a location hole in a clamping process of an existing tool of a box body with the cylinder type structure. The fixture for the box body with the cylinder type structure comprises a shell body. A location plate, a draw bolt, a guide sleeve, a spring guide bolt and a lower bottom base are arranged at the axis center position of the shell body from top to bottom in sequence. A lining is fixed on the inner side of the shell body. A guide sleeve reset spring is arranged between the spring guide bolt and the guide sleeve. A clamping sleeve with the lower portion provided with an annular step is arranged outside the guide sleeve in an enclosing manner. A bolt pillar reset spring is arranged between the clamping sleeve and the lower bottom base. An arc-shaped circular groove is formed in the lateral face of the lower portion of the draw bolt. A steel ball is fixed on the upper portion of the clamping sleeve. A cam ring is fixed on the upper side in the lining. The inner wall of the cam ring is tightly appressed to the steel ball and the surface of the inner wall of the cam ring is inclined inwards. An oil cylinder is arranged above the cam ring inside the shell body. A bolt plug is arranged on the lower portion in the lining. The fixture for the box body with the cylinder type structure is reasonable and reliable in design. Components can be convenient and reliable to clamp. Worker operation time can be reduced and work efficiency can be improved.

Description

technical field [0001] The invention relates to a positioning device for mechanical processing, in particular to a clamp for a cylindrical structure box. Background technique [0002] The casing of the barrel-type gearbox is large in size and thin in wall, and the shape of the casing lacks effective and reliable process positioning and pressing points. If the traditional tooling is designed with two pins on one side, the casing will be deformed during processing, resulting in The position of the bearing hole and the positioning hole for assembly of the finished product is seriously out of tolerance. Contents of the invention [0003] The present invention provides a clamp for a cylindrical structure box in order to solve the problem that the existing tooling for a cylindrical structure box easily causes deformation of the box during the clamping process, resulting in serious deviation of the positions of the bearing hole and the positioning hole. [0004] The present inve...
