Description

The spherical pad clamp

[technical field]

The utility model relates to a kind of clamp for the grinding of spherical pad spherical outside surface.

[background technology]

Spherical pad is the pad with inside and outside spherical surface, for more considerable spherical pads, the required precision of its inside and outside spherical surface is very high, so must process through grinding process, but, because the special shape of spherical pad and very thin thickness in order to improve grinding efficiency, need the special spherical pad clamp of design to improve clamping speed.And present spherical pad clamp is manual type to location, the clamp operation of spherical pad mostly, and inefficiency so the grinding efficiency of spherical pad is also very low, directly affects product yield and cost.

[summary of the invention]

For the deficiency that background technology exists, the purpose of this utility model is to be to provide a kind of grinding for the spherical pad spherical outside surface, and is easy to location, the clamp operation of spherical pad, improves the spherical pad clamp of working (machining) efficiency.

The utility model takes following technical scheme to finish:

The spherical pad clamp, comprise 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 to be ground, the spherical outside surface top circumference of clamp body is laid with a plurality of positioning core axles, the center line of positioning core axle and the rotation centerline of clamp body intersect vertically, it is characterized in that: the spherical outside surface of described clamp body is provided with Magnetic adhesive mat, and Magnetic adhesive mat is made by permanent-magnet material, and the Magnetic adhesive mat magnetic absorption is on the spherical outside surface of clamp body.

The spherical pad clamp of technique scheme, simultaneously a plurality of spherical pads are positioned by a plurality of positioning core axles, then clamp from both sides to the spherical pad of locating at positioning core axle by Magnetic adhesive mat, above-mentioned operation is very easy, so can greatly improve the grinding efficiency of spherical pad, improve product yield, reduce product cost.

[description of drawings]

The utility model has following accompanying drawing:

Fig. 1 is the shape assumption diagram of spherical pad clamp,

Fig. 2 is the A-A view of Fig. 1.

[specific embodiment]

As depicted in figs. 1 and 2, spherical pad clamp of the present utility model, comprise the clamp body 1 with spherical outside surface 2, spherical outside surface 2 radians of clamp body are identical with the Internal Spherical Surface radian of spherical pad 5 to be ground, spherical outside surface 2 top circumference of clamp body are laid with six positioning core axles 3, the center line of positioning core axle 3 and the rotation centerline of clamp body 6 intersect vertically, the spherical outside surface 2 of described clamp body is provided with Magnetic adhesive mat 4, Magnetic adhesive mat 4 is made by permanent-magnet material, Magnetic adhesive mat 4 magnetic absorptions are on the spherical outside surface 2 of clamp body, and a side of Magnetic adhesive mat 4 has the circular arc 4a identical with spherical pad 5 external diameters; Like this when spherical pad 5 behind positioning core axle 3 location, Magnetic adhesive mat 4 can better clamp (corresponding two Magnetic adhesive mats of spherical pad) to spherical pad 5 from the both sides of spherical pad 5, and clamping force is equivalent to the magnetic adsorptive power that Magnetic adhesive mat is adsorbed on the clamp body surface.

The utility model is like this operation: six spherical pads are positioned at six positioning core axles respectively, then mobile Magnetic adhesive mat is close to the both sides of Magnetic adhesive mat and spherical pad, realize the clamping to spherical pad, clamping force is exactly the magnetic adsorptive power that Magnetic adhesive mat is adsorbed on the clamp body surface, and the clamping force during the spherical pad grinding does not need very large.
