Eccentric pipe fitting chunk

Abstract

The invention relates to an eccentric pipe fitting chunk. The eccentric pipe fitting chunk comprises an inner clamping device, an eccentric connector and an outer supporting frame. The inner clampingdevice comprises an inner connection pipe. A limit ring is arranged on one end of the connection pipe, multiple slide grooves are formed in the inner wall of the connection pipe, the portions, corresponding to the limit ring, of the bottoms of the slide grooves are provided with sliding slopes, and a clamping propulsion mechanism is further arranged on the front end of the inner connection pipe. Clamping blocks are further arranged in the slide grooves and are in an isosceles trapezoid, and each extrusion slope and the corresponding slide slope are in contact with the two bevel edges of the corresponding clamping block respectively. The eccentric connector comprises two outer eccentric sheets and two inner eccentric sheets, the inner eccentric sheets and the outer eccentric sheets are in an arc shape, the outer arc sides of the outer eccentric sheets are in contact with the inner wall of the outer frame, the inner arc sides of the inner eccentric sheets are in contact with the outer wall of an inner frame, and the inner sides of the two arc ends of each outer eccentric sheet are located on the outer sides of the two arc ends of the corresponding inner eccentric sheet. Multiple compression bolts are annularly arranged on the outer supporting frame in an array mode, and the ends of the compression bolts are used for being in contact with the ends of the outer eccentric sheets.

Description

Technical field [0001] The invention relates to an eccentric pipe chuck, which belongs to the field of clamping equipment. Background technique [0002] Although the traditional three-jaw and four-jaw chuck can realize the eccentric clamping of the workpiece, the eccentric position can only face the fixed direction of the jaws, and the direction of the eccentric angle of the workpiece cannot be flexibly adjusted. Summary of the invention [0003] The technical problem to be solved by the present invention is to overcome the technical problem in the prior art and provide an eccentric pipe chuck. [0004] The technical solutions adopted by the present invention to solve its technical problems are: [0005] An eccentric pipe chuck, including an inner clamp, an eccentric connector, and a support outer frame; wherein the inner clamp includes an inner connecting pipe, one end of the connecting pipe is provided with a limiting ring, and the inner wall of the connecting pipe is processed Th...
