Multistage self-locking and positioning device

Abstract

The invention discloses a multistage self-locking and positioning device, wherein multiple through holes are formed in the side wall of a positioning sleeve; positioning pins are arranged in the through holes; screw sleeves are fixedly installed on the outer ends of the through holes; limiting steps are arranged on the positioning pins; springs are installed in the through holes; one end of each spring is pressed against the inner end face of the corresponding screw sleeve; the other end of each spring is pressed against the left end face of the corresponding limiting step; the lower end of a drive rod stretches into a center hole in the positioning sleeve and is fixedly connected with the multistage self-locking and positioning device; the upper end of a screw rod stretches out of the positioning sleeve; a multistage cone dish (3) is provided with multiple cylindrical sections (31) and conical sections (32) at intervals, which are gradually shrunken or amplified from top to bottom or from bottom to top; the right ends of the positioning pins are provided with shafts; pulleys cooperating with the multiple cylindrical sections and conical sections are arranged on the shafts. By the adoption of the multistage self-locking and positioning device, the multistage cone dish is driven through the drive rod, so that the stretching length of each positioning pin is controlled; at the moment, various devices can be positioned quickly; moreover, when a roller moves to the cylindrical sections, the positioning pins implement automatic locking on the roller; therefore, the multistage self-locking and positioning device is flexible to operate and reliable in positioning.

Description

technical field

[0001] The invention relates to the field of mechanical processing, in particular to a positioning and tightening device capable of realizing rapid positioning. Background technique

[0002] With the continuous development of machining technology, the traditional three-jaw chuck positioning can no longer meet the processing needs of parts with different structures. The clamping and positioning method of parts has always been a design focus in the processing field. In the processing of a special part that needs to be processed through the hole position, it is the key to the processing technology to design a positioning device that can be processed through the hole as a positioning surface. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a positioning and tightening device with simple and flexible operation and reliable positioning.
