Abstract

The utility model discloses a spherical washer grinding fixture, spherical spacer have interior sphere, spherical outside surface and a central hole, and the spherical outside surface is equipped with the inclined plane groove on the excircle border, and the direction in inclined plane groove is spherical spacer's radial direction, its characterized in that: grinding fixture is including the anchor clamps body that has the spherical outside surface, it is the same with spherical spacer's interior sphere radian to press from both sides specific spherical outside surface radian, the top circumference equipartition of the external sphere of anchor clamps is equipped with a plurality of locating pins, the central line and the specific rotation centerline of clamp of locating pin intersect vertically, the external diameter of locating pin matches with spherical spacer's central bore diameter, the side of locating pin is equipped with and presss from both sides tight piece, it has the outer inclined plane clamp plate of choosing that matches the inclined plane groove to press from both sides tight piece, the external sphere of anchor clamps corresponds the position that presss from both sides tight piece and is equipped with the spout, the tightly piece activity of pressing from both sides is set up by the screw in locating the spout. The utility model discloses can realize that the clamp force is big to spherical spacer's quick clamping, press from both sides tight reliably, make things convenient for grinding equipment to spherical spacer's abrasive machining, improve work efficiency.

Description

Spherical pad clamp
[technical field]
The utility model relates to a kind of clamp being exclusively used in spherical pad grinding.
[background technology]
Spherical pad is a kind of pad with inside and outside spherical surface, if the spherical outside surface precision of spherical pad and smoothness requirements high, so with regard to needing, grinding is carried out to the spherical outside surface of spherical pad.The thickness of spherical pad is thin, and there is no the clamping position that can utilize very well, although have employed the structure of a lot of method to spherical pad at present to improve to make spherical pad be easy to be clamped on clamp fix, but that ubiquitous problem is clamping force is little, it is unreliable to clamp, if the slightly large workpiece that just easily causes of the grinding allowance of emery wheel feed departs from fixture, cause potential safety hazard, especially more can be like this for the spherical pad that size is large.
[summary of the invention]
In view of current known technology Problems existing, problem to be solved in the utility model is to provide a kind of quick-clamping realized spherical pad, and clamping force is large, reliable clamping, facilitate equipment for grinding to the grinding of spherical pad, the spherical pad clamp of increasing work efficiency.
For solving the problems of the technologies described above, the utility model takes following technical scheme:
Spherical pad clamp, the spherical pad of institute's grinding has Internal Spherical Surface, spherical outside surface and central bore, spherical outside surface is provided with surface groove on outer circumferential edge edge, the direction of surface groove is the radial direction of spherical pad, it is characterized in that: clamp comprises the clamp body with spherical outside surface, 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 central bore diameter compatible of spherical pad, the side of alignment pin is provided with clamp, clamp has coupling the outer of surface groove and chooses inclined-plane pressing plate, the position of the corresponding clamp of clamp body spherical outside surface is provided with chute, clamp activity is located in chute and is tightened up by screw.
In technique scheme, because the spherical outside surface of spherical pad is provided with surface groove, so clamp can realize the quick-clamping to spherical pad on outer circumferential edge edge, clamping force is large, reliable clamping, facilitates equipment for grinding to the grinding of spherical pad, increases work efficiency.Detailed process is: before the grinding work carrying out spherical pad, the Internal Spherical Surface of spherical pad being against is placed on the spherical outside surface of clamp body, the central bore of alignment pin to spherical pad positions, then the inclined-plane pressing plate aligning surface groove that clamp makes to choose outside clamp is moved, then turning screw is fixed tightly in chute by clamp, now surface groove will compress and then be fixed by spherical pad by inclined-plane pressing plate, owing to being from compressing the inclined-plane of surface groove above, such clamping force can be larger, so spherical pad would not occur throwing away the phenomenon departing from clamp outward in the rotation process of clamp, reliable clamping.
[accompanying drawing explanation]
The utility model has following accompanying drawing:
Fig. 1 is the structural representation of the spherical pad of the utility model institute grinding;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the structural representation of clamp.
[detailed description of the invention]
Drawings illustrate the technical solution of the utility model and embodiment, further describe each details and the operation principle thereof of embodiment below more by reference to the accompanying drawings.
As shown in Figure 1, 2, the spherical pad 1 of the utility model institute grinding, there is Internal Spherical Surface, spherical outside surface and central bore, spherical outside surface processes two place's surface grooves 2 on outer circumferential edge edge, two place's surface grooves 2 are arranged along staggering 180 ° in the outer circumferential edge of spherical outside surface, the direction of surface groove 2 is the radial direction of spherical pad, is 45-60 ° between the bevel angle of surface groove 2 and level.
As shown in Figure 3, spherical pad clamp of the present utility model, comprise the clamp body 6 with spherical outside surface 4, spherical outside surface 4 radian of clamp body 6 is identical with the Internal Spherical Surface radian of spherical pad 1, the top circumference of clamp body spherical outside surface 4 is laid with four alignment pins 3, the center line 10 of alignment pin 3 intersects vertically with the rotation centerline 8 of clamp body 6, the external diameter of alignment pin 3 and the central bore diameter compatible of spherical pad 1, the left and right side of alignment pin 3 is provided with clamp 5, clamping 5 has coupling the outer of surface groove 2 and chooses inclined-plane pressing plate 51, the position of the corresponding clamp 5 of clamp body spherical outside surface 4 is provided with chute 9, clamp 5 activity is located in chute 9 and is tightened up by screw 7.
