Description
[technical field]
The utility model relates to the fixture of a kind of spherical pad and grinding 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 do not have the clamping position that can utilize very well, so will carry out grinding to spherical pad, a kind of method is the structure by changing traditional clamp, but limitation is many, can not be suitable for the spherical pad of various material; Another kind method is under the prerequisite not destroying spherical pad using function, improve the structure of spherical pad itself, make spherical pad be easy to clamped, but difficulty 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 one can realize quick-clamping and reliably fix, and improves spherical pad and the clamp of work efficiency.
For solving the problems of the technologies described above, the utility model takes following technological scheme:
Spherical pad, there is inner ball surface, outer spherical surface and central bore, it is characterized in that: sphere is provided with through upper and lower elongated hole groove, the length direction of elongated hole groove is along the circumferencial direction of spherical pad, one end of elongated hole groove is the large slotted eye of relatively large radius and the other end is the little slotted eye of small radii, is provided with curve transition between size slotted eye.Elongated hole groove is provided with two in the bilateral symmetry position of central bore, and two elongated hole grooves have identical turning to.
In technique scheme, the structure of spherical pad improves under the prerequisite not destroying using function, the respective design that mating mold is set of elongated hole groove, spherical pad can be made to be easy to the quick-clamping realized on clamp fix with reliable, facilitate equipment for grinding to the grinding of spherical pad, improve work efficiency.
Clamp comprises the fixture with outer spherical surface, the outer spherical surface radian of fixture is identical with the inner ball surface radian of spherical pad, the top circumference of fixture outer spherical surface is laid with multiple locating stud, the center line of locating stud and the rotation centerline of fixture intersect vertically, the external diameter of locating stud and the diameter of bore of spherical pad match, the side of locating stud is provided with elastic clamping pin, elastic clamping pin is aimed at the elongated hole groove of spherical pad, and the aperture that the external diameter of elastic clamping pin is less than the large slotted eye of elongated hole groove is greater than the aperture of the little slotted eye of elongated hole groove.Elastic clamping pin is hollow cylinder structure, and longitudinal grooving that the cylinder of elastic clamping pin offers many same intervals distances makes the cylindrical of elastic clamping pin have elasticity.
In technique scheme, because spherical pad is provided with elongated hole groove on sphere, elongated hole groove has large end and small end, so clamp is easy to realization to the quick-clamping of spherical pad with reliable fixing, facilitate equipment for grinding to the grinding of spherical pad, improve work efficiency.Detailed process is: before the grinding work carrying out spherical pad, the inner ball surface of spherical pad being against is placed on the outer spherical surface of fixture, the endoporus of locating stud to spherical pad positions, the elastic clamping pin that large slotted eye and the clamp outer spherical surface of elongated hole groove are provided with is aimed at, then toward a direction rotation spherical pad, so the little slotted eye of elongated hole groove also slowly can extrude elastic clamping pin near elastic clamping pin, thus make spherical pad on clamp, obtain quick-clamping and reliably fix, facilitate equipment for grinding to the grinding of spherical pad, improve work efficiency.
[accompanying drawing explanation]
The utility model has following accompanying drawing:
Fig. 1 is the structural representation of spherical pad,
Fig. 2 is the A-A sectional view of Fig. 1,
Fig. 3 is the structural representation of clamp.
[embodiment]
Drawings illustrate the technical solution of the utility model and embodiment, further describe each details and the working principle thereof of embodiment below more by reference to the accompanying drawings.
As shown in Figure 1, 2, spherical pad 1 of the present utility model, there is inner ball surface, outer spherical surface and central bore, sphere is provided with through upper and lower elongated hole groove 2, elongated hole groove 2 is provided with two in the bilateral symmetry position of central bore, and two elongated hole grooves have identical turning to, and the length direction of elongated hole groove 2 is along the circumferencial direction of spherical pad 1, one end of elongated hole groove 2 is the large slotted eye 22 of relatively large radius and the other end is the little slotted eye 21 of small radii, is provided with curve transition between size slotted eye.
As shown in Figure 3, clamp of the present utility model, comprise the fixture 6 with outer spherical surface 5, outer spherical surface 5 radian of fixture 6 is identical with the inner ball surface radian of spherical pad 1, the top circumference of fixture outer spherical surface 5 is laid with six locating studs 3, the center line of locating stud 3 and the rotation centerline 7 of fixture 6 intersect vertically, the external diameter of locating stud 3 and the diameter of bore of spherical pad 1 match, the side of locating stud 3 is provided with elastic clamping pin 4, elastic clamping pin 4 is hollow cylinder structure, longitudinal grooving 41 that the cylinder of elastic clamping pin 4 offers many same intervals distances makes the cylindrical of elastic clamping pin 4 have elasticity, elastic clamping pin 4 is aimed at the elongated hole groove 2 of spherical pad, the aperture that the external diameter of elastic clamping pin 4 is less than the large slotted eye of elongated hole groove 22 is greater than the aperture of the little slotted eye 21 of elongated hole groove.
Above-mentioned clamp carries out quick-clamping to above-mentioned spherical pad like this and reliably fixes: before grinding spherical pad, the inner ball surface of six spherical pads 1 being against is placed on the outer spherical surface 5 of clamp, positioned by the endoporus of locating stud 3 pairs of spherical pads 1, first the large slotted eye 22 of elongated hole groove is aimed at elastic clamping pin 4, then toward a direction rotation spherical pad 1, so the little slotted eye 21 of elongated hole groove also slowly can extrude elastic clamping pin 4 near elastic clamping pin 4, thus make spherical pad 1 on clamp, obtain quick-clamping and reliably fix, improve work efficiency, after above-mentioned preparatory work completes, the grinding of spherical pad can be carried out.
