Abstract
The invention discloses a finish turning fixture for a reducing sleeve. The finish turning fixture for the reducing sleeve comprises a disk-shaped fixing base, positioning tables and positioning pins, the positioning tables are arranged on a fixing surface of the fixing base contacting with a workpiece, each positioning pin is arranged on the upper surface of each positioning table, the axis of each positioning pin is perpendicular to the upper surface of the corresponding positioning table, the upper surface of each positioning table is perpendicular to the fixing surface of the fixing base, and the distance between the upper surface of each positioning table and the circle center of the fixing seat is equal to that between the plane at the side edge of the reducing sleeve and the circle center of a mouth of the reducing sleeve. The distance between the axis of each positioning pin and the fixing surface of the fixing base is equal to that between the axis of each elongated hole of the reducing sleeve and the end face of the reducing sleeve, and the distance between the axes of the two positioning pins is equal to that between the axes of the elongated holes at the side edge of the reducing sleeve. By the means, the reducing sleeve can be better clamped, processing precision is improved, surface roughness is reduced, the processed reducing sleeve is short in running-in time, and service life of the reducing sleeve is prolonged.
Description
Technical field
The present invention relates to finish turning frock field, particularly relate to a kind of reducing sleeve finish turning frock.
Background technology
At present the technique of processing reducing sleeve mainly comprises the techniques such as punch forming, rough turn, boring, finish turning, correct grinding, polishing, and because the reducing sleeve external structure is irregular, can't accurately locate with traditional clamping method, positioning process is also more complicated loaded down with trivial details, and there are the defectives such as rough surface, chamfering be inhomogeneous in the reducing sleeve that adopts existing explained hereafter to go out, and running-in time is long after the installation, and the abrasive particle of formation is many in the reducing sleeve, scratch easily workpiece, and working (machining) efficiency is low.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of reducing sleeve finish turning frock, and better the clamping reducing sleeve improves machining accuracy and working (machining) efficiency, so that finished reducing sleeve running-in time is short, has increased the service life of reducing sleeve.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of reducing sleeve finish turning frock is provided, comprises: firm banking, positioning table and locating pin; Described firm banking is discoid; Described positioning table is arranged on firm banking and the stationary plane that workpiece contacts; Described locating pin is arranged on the positioning table upper surface, and the axle center of locating pin is vertical with the positioning table upper surface, described positioning table upper surface is vertical with the stationary plane of firm banking, and the positioning table upper surface equates with the distance of reducing sleeve side plane to the reducing sleeve running-on center of circle to the distance in the firm banking center of circle; The distance of described locating pin axle center between the stationary plane of firm banking equate with the distance of reducing sleeve elongated hole axle center to the reducing sleeve end face, between the axle center of described locating pin apart from equating with distance between the axle center of elongated hole on the reducing sleeve side.
The invention has the beneficial effects as follows: the present invention is the clamping reducing sleeve better, improves machining accuracy and working (machining) efficiency, and so that finished reducing sleeve running-in time is short, has increased the service life of reducing sleeve.
Description of drawings
Fig. 1 is that the master of a kind of reducing sleeve finish turning of the present invention frock looks schematic diagram;
Fig. 2 be shown in an a kind of left side of reducing sleeve finish turning frock look schematic diagram;
Fig. 3 be shown in master during a kind of reducing sleeve finish turning frock clamping reducing sleeve look schematic diagram;
Fig. 4 be shown in left side during a kind of reducing sleeve finish turning frock clamping reducing sleeve look schematic diagram;
The mark of each parts is as follows in the accompanying drawing: 1, firm banking; 2, positioning table; 3, locating pin; 4, reducing sleeve.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also Fig. 1 to Fig. 4, the embodiment of the invention comprises:
A kind of reducing sleeve finish turning frock comprises: firm banking 1, positioning table 2 and locating pin 3; Described firm banking 1 is discoid; Described positioning table 2 is arranged on firm banking 1 and the stationary plane that workpiece contacts; Described locating pin 3 is arranged on positioning table 2 upper surfaces, and the axle center of locating pin 3 is vertical with positioning table 2 upper surfaces, described positioning table 2 upper surfaces are vertical with the stationary plane of firm banking 1, and positioning table 2 upper surfaces equate with the distance of reducing sleeve 4 side planes to the reducing sleeve running-on center of circle to the distance in firm banking 1 center of circle; The elongated hole axle center of the distance of described locating pin 3 axle center between the stationary plane of firm banking 1 and reducing sleeve 4 equates to the distance of the end face of reducing sleeve 4, between the axle center of described locating pin 3 apart from equating with distance between the axle center of elongated hole on reducing sleeve 4 sides.During clamping reducing sleeve 4, only need the elongated hole of reducing sleeve 4 sides is aimed at the locating pin 3 of finish turning frock, and insert locating pin 3, easy to operate, and can improve machining accuracy and working (machining) efficiency, increased the service life of reducing sleeve.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
