Abstract
The utility model discloses a fixture for a grinding spherical gasket. The chuck of the fixture is provided with an outer spherical arc surface or an inner spherical arc surface. Positioning pins are arranged on the spherical arc surface. The axis of each positioning pin passes through the center of the spherical arc surface and is perpendicular to the rotating centerline of the chuck. The fixture is characterized in that each positioning pin is provided with an elastic opening, a jacking screw is arranged on the side of the positioning pin, and under the effect of the jacking screw, the elastic opening of the positioning pin can be shrunk and expanded. The fixture can be used for simultaneously and rapidly clamping and fixing a plurality of spherical gaskets and the use of the fixture is not restricted by whether the materials of the spherical gaskets have magnetism or not.
Description
[technical field]
The utility model relates to a kind of anchor clamps, what be specifically related to is a kind of anchor clamps of grinding spherical pad.
[background technology]
Spherical pad refers to the pad with spherical arc, for the sphere precision that improves spherical pad need be carried out grinding to the spherical arc of spherical pad, for improving grinding efficiency, also need a plurality of spherical pads are carried out quick-clamping and fixing simultaneously, the applicant has applied for the utility model patent of patent No. ZL200820165879.5 " a kind of anchor clamps that are used for grinding spherical pad " on October 11st, 2008 for this reason, the technical scheme that this utility model patent discloses is: the anchor clamps that are used for grinding spherical pad, comprise fixedly connected flange and chuck, described chuck has the spherical arc identical with spherical pad, is provided with solenoid in the described chuck; Described chuck spherical arc is provided with shop bolt, and the axis of this shop bolt is by the chuck sphere centre and perpendicular to the rotation of anchor clamps, and the external diameter of shop bolt and spherical pad diameter of bore match.The spherical pad that the fine suitable magnetic material of technique scheme energy is made, because it can be adsorbed on by the magnetic force of solenoid on the chuck spherical arc and fix, and these do not have the spherical pad that magnetic material makes just powerless concerning metallic copper.
[summary of the invention]
Deficiency at the prior art existence, the technical problems to be solved in the utility model is to be to provide a kind of can carry out quick-clamping and fixing to a plurality of spherical pads simultaneously, and whether the material of spherical pad has the unrestricted grinding spherical pad anchor clamps of magnetic.
The utility model is implemented by the following technical programs:
The anchor clamps of grinding spherical pad, its chuck portion has outer spherical cambered surface or interior spherical arc, spherical arc is provided with shop bolt, the axis of shop bolt is by the spherical arc center and perpendicular to the rotation centerline of chuck, it is characterized in that: described shop bolt has elastic opening, the side of shop bolt is provided with the roof pressure screw, and under the effect of roof pressure screw, the elastic opening of shop bolt can shrink and open.
The utility model by the roof pressure screw precession or withdraw from, make the elastic opening of shop bolt shrink or open, change the location diameter of shop bolt, make between the endoporus of shop bolt and spherical pad and unclamp mutually or tensioner, if unclamp between the two, about spherical pad can make things convenient for, if tensioner between the two, spherical pad just is fixed on the chuck so, it is fixing that its mode of tightening up is different from the magnetic force absorption of prior art, so the utility model not only can be simultaneously carry out quick-clamping and fixing to a plurality of spherical pads as prior art, and the material of spherical pad whether to have magnetic unrestricted.

[specific embodiment]
Accompanying drawing 1,2 has been represented the structure of spherical pad.
Shown in Fig. 3,4, the anchor clamps of grinding spherical pad (spherical pad spherical outside surface), 3 ones of chucks and 4 ones of flanges by integrative-structure are formed, 3 ones of chucks have outer spherical cambered surface 5, the radian of outer spherical cambered surface 5 is identical with the Internal Spherical Surface radian of spherical pad to be ground, outer spherical cambered surface 5 is provided with six shop bolts 1, shop bolt 1 is fixedlyed connected with chuck 3 by screw, the axis of shop bolt is by the spherical arc center and perpendicular to the rotation centerline of chuck, and the external diameter of shop bolt is a bit larger tham the diameter of bore of spherical pad; As Fig. 7, shown in 8, the anchor clamps of grinding spherical pad (spherical pad Internal Spherical Surface), by 8 ones of fixedly connected chucks and flange 10,11 compositions, 8 ones of chucks have interior spherical arc 9, the radian of interior spherical arc 9 is identical with the spherical outside surface radian of spherical pad to be ground, interior spherical arc 9 is provided with six shop bolts 1, shop bolt 1 is fixed on the cover plate 7 by screw fixedlys connected with chuck 8 by cover plate 7 again, the axis of shop bolt is by the spherical arc center and perpendicular to the rotation centerline of chuck, and the external diameter of shop bolt is a bit larger tham the diameter of bore of spherical pad; Described shop bolt 1 is the middle cylinder that is provided with screw hole, be symmetrily processed with two top-down longitudinal cuts (shown in Fig. 5,6) on the cylinder of shop bolt, these two longitudinal cuts have formed the elastic opening 6 of shop bolt, the side of shop bolt 1 is provided with roof pressure screw 2, roof pressure screw 2 is threaded on the outer face of chuck 3 and 8, by precession or withdraw from roof pressure screw 2, can make the elastic opening 6 of shop bolt 1 shrink or open, change the location diameter of shop bolt, thereby realize unclamping and clamp spherical pad.When precession roof pressure screw, roof pressure screw roof pressure shop bolt, the elastic opening of shop bolt shrinks, the location diameter of shop bolt diminishes, can be located at the inner hole sleeve of spherical pad to be ground the shop bolt cylindrical this moment, outwards withdraw from the roof pressure screw then, when withdrawing from the roof pressure screw, the elastic opening of shop bolt opens elasticity, the location diameter of shop bolt becomes big, so shop bolt can tensioner be fixed on spherical pad on the chuck at the endoporus of spherical pad, thereby realize clamping to spherical pad.
