Description

A kind of grinding spherical pad spherical outside surface fixture
[technical field]
The present invention relates to a kind of clamp for the grinding of spherical pad spherical outside surface.
[background technology]
Spherical pad is a kind of pad with inside and outside spherical surface, the key of spherical pad is its sphere precision and fineness, for more considerable spherical pads, spherical outside surface precision and smoothness requirements high, spherical outside surface just must can reach required precision and fineness through grinding.The patent No. 200810121605.0, the technical scheme that patent name " fixture for grinding spherical pad " provides solves above-mentioned technical problem preferably, but shortcoming is the spherical pad that can only be suitable for ferrous material, for some not by the copper material spherical pad of magnetic absorption, just have no idea to utilize above-mentioned patented technology to implement grinding, applicant also used certain methods and solved above-mentioned technical problem afterwards, also Patents has been applied for, but on the whole, all to be clamped spherical pad one by one by manual type, speed is slower, obviously requirements of mass production can not be met, more seriously, also there is spherical pad can not reliably fix on fixture, clamp illusive problem, spherical pad is easily deviate from when carrying out grinding.
[summary of the invention]
In view of current known technology Problems existing, the technical problem to be solved in the present invention is to provide a kind of grinding for spherical pad spherical outside surface, can realize fixing with reliable the quick-clamping of spherical pad, the grinding spherical pad spherical outside surface fixture of increasing work efficiency.
For solving the problems of the technologies described above, the present invention takes following technical scheme:
A kind of grinding spherical pad spherical outside surface fixture, the spherical pad of institute's grinding diametrically arranges a narrow connected in star on spherical outside surface, it is characterized in that: described fixture comprises the clamp body with spherical outside surface and the concrete ring flange of geometrical clamp, the spherical outside surface radian of clamp body is identical with the Internal Spherical Surface radian of spherical pad, the top circumference of clamp body spherical outside surface is laid with multiple alignment pin, the center line of alignment pin and the rotation centerline of clamp body intersect vertically, the external diameter of alignment pin and the diameter of bore of spherical pad match, the top of alignment pin is provided with the transverse groove corresponding with narrow connected in star, the setting direction of transverse groove is the top circumference direction of clamp body spherical outside surface, during grinding work, the spherical pad be arranged on clamp body spherical outside surface carries out Internal hole positioning by alignment pin and carries out tighten by band rope, the winding of band rope forms a circle on clamp body spherical outside surface, band rope is through narrow connected in star and transverse groove, band rope is highly less than the narrow connected in star degree of depth, the end face outside of clamp body is fixedly connected with end cap, the end face outside of end cap arranges portable plate and adjusting screw(rod), adjusting screw(rod) is threaded on end cap, the rod end of adjusting screw(rod) arranges handwheel, portable plate rotates to be located on adjusting screw(rod) and moves axially with adjusting screw(rod), band rope two ends enter into clamp body endoporus through clamp body spherical outside surface, then the Central Symmetry two ends of portable plate are connected to through end cap.
The fixture of technique scheme, first the alignment pin of clamp body spherical outside surface is utilized to position spherical pad, then utilize the band rope of tension to carry out tighten or clamping to all spherical pads simultaneously, structure is simple, no matter can be applicable to is the spherical pad of irony, copper or other material, not only realizing quick-clamping, and realize reliable fixing, can never there is deviating from phenomenon when carrying out grinding in spherical pad.Its operation principle is: when grinding spherical pad, multiple spherical pad is arranged in simultaneously on clamp body spherical outside surface, positioned by the endoporus of alignment pin to spherical pad, the narrow connected in star of spherical pad is allowed to align with the transverse groove of alignment pin, and allow band rope through narrow connected in star and transverse groove, then rotating handwheel makes adjusting screw(rod) produce the action exiting end cap, such adjusting screw(rod) will drive portable plate to move axially toward the direction away from end cap, band rope is strained, so all spherical pads are carried out tighten simultaneously, in any case the spherical pad after tighten also can not be deviate from from alignment pin, thus guarantee quick-clamping and reliably fix, improve working (machining) efficiency, next the processing of grinding spherical pad spherical outside surface can be carried out.
[accompanying drawing explanation]
The present invention has following accompanying drawing:
The spherical pad that Fig. 1 is institute of the present invention grinding overlook directional diagram,
Fig. 2 is the sectional view of Fig. 1,
Fig. 3 is shape assumption diagram of the present invention,
Fig. 4 is the right view of Fig. 3,
Fig. 5 is that the axle of Fig. 3 cuts open figure,
