Abstract
The utility model discloses a novel spherical spacer has interior sphere, spherical outside surface and central hole, its characterized in that: several inclined plane grooves are processed out to the spherical outside surface on the excircle border, the direction in inclined plane groove is spherical spacer's radial direction. The utility model discloses a spherical spacer can realize that the quick clamping on grinding fixture is fixed, and the clamp force is big, presss from both sides tightly reliably, makes things convenient for abrasive machining.
Description
[technical field]
The utility model relates to a kind of improvement invention of spherical pad.
[background technique]
Spherical pad is a kind of pad with inside and outside spherical surface, if the outer spherical surface precision of spherical pad and smoothness requirements high, so with regard to needing, grinding is carried out to the outer spherical surface of spherical pad.But, 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 on clamp to fix, and clamping force is large, and reliable clamping, facilitates the new spherical pad of grinding.
For solving the problems of the technologies described above, the utility model takes following technological scheme:
New spherical pad, has inner ball surface, outer spherical surface and central bore, it is characterized in that: outer spherical surface processes several places surface groove on outer circumferential edge edge, and the direction of surface groove is the radial direction of spherical pad.
In technique scheme, the outer spherical surface of spherical pad has been provided with several places surface groove on outer circumferential edge edge, the setting of surface groove can conveniently utilize clamp effectively compress its inclined-plane and do not affect grinding, clamping force can be larger, owing to compressing inclined-plane, so spherical pad would not occur throwing away the phenomenon departing from clamp outward, reliable clamping in the rotation process of clamp, thus facilitate grinding.
As preferably, surface groove is provided with two places in the outer circumferential edge of outer spherical surface along staggering 180 °.
As preferably, be 45-60 ° between the bevel angle of surface groove and level.
[accompanying drawing explanation]
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the A-A sectional view of Fig. 1.
[embodiment]
As shown in the figure, new spherical pad of the present utility model, there is inner ball surface, outer spherical surface 1 and central bore, outer spherical surface 1 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 outer spherical surface 1, 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.
Claims (3)
1. new spherical pad, has inner ball surface, outer spherical surface and central bore, it is characterized in that: outer spherical surface processes several places surface groove on outer circumferential edge edge, and the direction of surface groove is the radial direction of spherical pad.
2. new spherical pad as claimed in claim 1, is characterized in that: surface groove is provided with two places in the outer circumferential edge of outer spherical surface along staggering 180 °.
3. new spherical pad as claimed in claim 1, is characterized in that: be 45-60 ° between the bevel angle of surface groove and level.
