Problems solved by technology

Generally, there are two methods for turning eccentric workpieces: (1) Clamping eccentric workpieces on three-jaw or four-jaw chucks through pads, this method has low processing efficiency and poor precision; (2) Turning on special fixtures For eccentric workpieces, although the processing accuracy can be well guaranteed by using special fixtures, the cost is high and the versatility is poor

Abstract

The invention discloses a regulable eccentric chuck. The regulable eccentric chuck comprises a fixing chuck, a clamping chuck and a positioning flange plate, wherein the positioning flange plate is fixedly clamped on the fixing chuck, and a plurality of mounting holes are formed in the positioning flange plate; the clamping chuck is fixedly mounted on the positioning flange plate through the mounting holes, the mounting holes adopt a bar-shaped groove structure, the mounting holes are mutually in parallel in the lengthwise direction, a threaded hole is formed in one jack catch on the clamping chuck, and a positioning bolt is mounted in the threaded hole. The regulable eccentric chuck disclosed by the invention is reformed from a general three-jaw chuck, can be used for production of eccentric parts in batches, and has high production efficiency; the processing accuracy can be effectively controlled through rough regulation and fine regulation in the process of using the regulable eccentric chuck, and the regulable eccentric chuck has the characteristics of high efficiency, high accuracy and low cost.

Description

technical field [0001] The invention relates to a clamping chuck, in particular to an eccentric chuck with adjustable eccentric distance. Background technique [0002] The eccentric workpiece is the outer circle and the outer circle of the part, or the outer circle and the axis of the inner hole are parallel but not coincident, and deviate from a certain distance. When processing such eccentric parts, measures are usually taken in terms of clamping, that is, the axis of the eccentric part to be processed is aligned to coincide with the rotation axis of the lathe spindle. Generally, there are two methods for turning eccentric workpieces: (1) Clamping eccentric workpieces on three-jaw or four-jaw chucks through pads, this method has low processing efficiency and poor precision; (2) Turning on special fixtures For eccentric workpieces, although the processing accuracy can be well guaranteed by using special fixtures, the cost is high and the versatility is poor.
