Abstract

The utility model discloses an eccentric supporting and positioning device which belongs to an auxiliary tool for mechanical processing. The eccentric supporting and positioning device is characterized by consisting of a fixed seat, an eccentric shaft, a rotating handle and a fastening screw, wherein an eccentric supporting shaft is arranged at the front end of the eccentric shaft; an eccentric annular groove is arranged in the middle of the eccentric shaft; a radial tapered hole is arranged at the rear part of the eccentric shaft; the eccentric shaft is sleeved in an inner hole of the fixed seat; a threaded through hole is arranged in the fixed seat corresponding to the eccentric annular groove; the fastening screw is screwed in the threaded through hole; the rotating handle is sleeved on the rear end part of the eccentric shaft; and a tapered pin is inserted into the tapered hole in the eccentric shaft to fix the rotating shaft on the rear end part of the eccentric shaft. When the eccentric supporting and positioning device is used, the fastening screw is loosened firstly, then the rotating handle is rotated, and the eccentric supporting shaft at the front end of the eccentric shaft is in tight contact with a workpiece; and then the fastening screw is tightly screwed to lock the eccentric shaft, the adjustment is convenient, the positioning is accurate, and the eccentric supporting and positioning device has wide application range.

Description

A kind of eccentric support positioner

Technical field

The utility model relates to a kind of aid of machining, particularly a kind of eccentric support positioner.

Background technology

At present, in machining, adopt the auxiliary locator as workpiece such as rest pad, spring usually, adjust more loaded down with trivial detailsly, use inconveniently, versatility is poor.

Summary of the invention

The purpose of the utility model is in order to overcome above-mentioned weak point, and provides a kind of easy to adjust, accurate positioning, eccentric support positioner applied widely.

The purpose of the utility model is achieved in that a kind of eccentric support positioner; It is characterized in that it is made up of holder, eccentric shaft, rotary handle, fastening screw; Wherein the eccentric shaft front end has to have on eccentric support axle, the middle part cylindrical and has the radial taper hole in eccentric cannelure, the rear portion; Be inserted in the endoporus of holder at the eccentric shaft middle part, and both matched in clearance have tapped through hole in the holder of corresponding eccentric cannelure; Fastening screw screws in the tapped through hole, the bottom is on the eccentric fastener shaft of the annular bottom land of off-centre; Rotary handle packs on the eccentric shaft rearward end, has the conical through-hole consistent with the radial taper hole in the holder at the two ends, radial taper hole in the corresponding eccentric shaft rear portion, inserts in the bellmouth through cone pin rotary handle is fixed on the eccentric shaft rearward end.

The utility model during use, unclamps fastening screw owing to adopt above design earlier, rotates rotary handle, and the eccentric support axle that makes the eccentric shaft front end is with after workpiece closely contacts, and the fastening screw of screwing again locks eccentric shaft.Easy to adjust, accurate positioning, applied widely.
