Abstract
The utility model discloses a fixture for grinding an inner spherical surface of a spherical gasket. The fixture is characterized by comprising a flange and a chuck which are fixedly connected with each other; the chuck is provided with an inner spherical cambered surface, the radian of the inner spherical cambered surface is equal to the radian of the outer spherical surface of the spherical gasket to be ground, a plurality of positioning pins are arranged on the inner spherical cambered surface, and the axis of each positioning pin passes through the top of the inner spherical cambered surface to be vertically intersected with the rotation axis of the fixture; the head part of each positioning pin is in a hollow tube body structure, the tube wall of each hollow tube body has non-uniform thickness, longitudinal cutting grooves are machined in the tube wall of each hollow tube body, and a rotatable cam block is arranged in the inner hole of each hollow tube body; and each cam block rotates to lean against the tube wall of the corresponding hollow tube body, so as to enable the head part of the corresponding positioning pin to elastically open. The fixture is specially for grinding the inner spherical surface of the spherical gasket and can realize the rapid and simultaneous clamping of multiple spherical gaskets.
Description
Technical field
The utility model relates to a kind of anchor clamps, is specifically related to a kind of anchor clamps of grinding spherical pad Internal Spherical Surface.
Background technology
Spherical pad is a kind of pad with spherical arc, the key of spherical pad is its sphere precision and fineness, at present, spherical pad is by the punch ram moulding, its spherical surface error is big, fineness is not high, so some sphere precision, the demanding spherical pad of fineness need be carried out the grinding of Internal Spherical Surface and spherical outside surface, and in order to improve grinding efficiency, need the special clamp of design to improve clamping speed, and preferably can a plurality of spherical pads of disposable while clamping.
Summary of the invention
The purpose of this utility model is to be to provide a kind of grinding spherical pad Internal Spherical Surface that is exclusively used in, and can realize a plurality of spherical pads are carried out simultaneously the grinding spherical pad Internal Spherical Surface anchor clamps of quick-clamping.
The utility model is implemented by the following technical programs:
A kind of anchor clamps of grinding spherical pad Internal Spherical Surface, it is characterized in that: comprise fixedly connected flange and chuck, chuck has interior spherical arc, the radian of interior spherical arc is identical with the radian of spherical pad spherical outside surface to be ground, interior spherical arc is provided with a plurality of shop bolts, the axis of each shop bolt by interior spherical arc the top and intersect vertically with the rotation of anchor clamps; The head of described shop bolt is the hollow pipe body structure, and hollow body has the not tube wall of uniform thickness, offers vertical grooving on the tube wall of hollow body, and the endoporus of hollow body is provided with rotating cam bit; After cam bit rotated, the tube wall that cam bit leans hollow body opened the head elasticity of shop bolt.
The utility model is so a plurality of spherical pads to be carried out quick-clamping simultaneously: with the inner hole sleeve of the spherical pad head at shop bolt, rotatable cam blocks then, behind the rotatable cam blocks certain angle, the tube wall that cam bit can lean hollow body opens the head elasticity of shop bolt, so spherical pad is carried out quick-clamping, owing to be provided with a plurality of shop bolts, so can carry out quick-clamping simultaneously to a plurality of spherical pads.Owing to realized the quick-clamping of a plurality of spherical pads, so can effectively improve grinding efficiency, be fit to very much the Internal Spherical Surface grinding of some sphere precision, the demanding spherical pad of fineness.
Description of drawings
The utility model has the following drawings:
Fig. 1 is structure chart of the present utility model,
Fig. 2 is the A-A view of Fig. 1,
Fig. 3 is that M amplifies to view is local among Fig. 2,
Fig. 4 is the view after Fig. 3 cam piece rotates 90o.
The specific embodiment
Come the utility model is described in detail below by specific embodiment:
As shown in the figure, the anchor clamps of grinding spherical pad Internal Spherical Surface of the present utility model, comprise fixedly connected flange 2 and chuck 1, chuck 1 has interior spherical arc, the radian of interior spherical arc is identical with the radian of spherical pad spherical outside surface to be ground, interior spherical arc is provided with six shop bolts 3, the axis of each shop bolt 3 by interior spherical arc the top and intersect vertically with the rotation 10 of anchor clamps; The head of described shop bolt 3 is the hollow pipe body structure, offer two vertical groovings 5 of symmetry on the tube wall of hollow body, article two, vertical grooving 5 is divided into the identical two halves in the left and right sides with the tube wall of hollow body, hollow body has the not tube wall of uniform thickness, tube wall from b to a place thickening slowly, the endoporus of hollow body is provided with rotating cam bit 4, and cam bit 4 is connected with handle 7 by outer boom 6; Shown in Figure 3, cam bit does not contact with the tube wall of hollow body; Shown in Figure 4, after cam bit rotated 90o, the tube wall that cam bit leans hollow body opened the head elasticity of shop bolt, and described shop bolt 3 adopts nylon material.
The utility model is work like this: the head that the endoporus of six spherical pads successively is enclosed within six shop bolts, pull the handle rotatable cam blocks then, behind the rotatable cam blocks certain angle, the tube wall that cam bit can lean hollow body opens the head elasticity of shop bolt, so spherical pad is carried out quick-clamping, owing to realized the quick-clamping of a plurality of spherical pads, so can effectively improve grinding efficiency, be fit to very much the Internal Spherical Surface grinding of some sphere precision, the demanding spherical pad of fineness.
Claims (2)
1. the anchor clamps of a grinding spherical pad Internal Spherical Surface, it is characterized in that: comprise fixedly connected flange and chuck, chuck has interior spherical arc, the radian of interior spherical arc is identical with the radian of spherical pad spherical outside surface to be ground, interior spherical arc is provided with a plurality of shop bolts, the axis of each shop bolt by interior spherical arc the top and intersect vertically with the rotation of anchor clamps; The head of described shop bolt is the hollow pipe body structure, and hollow body has the not tube wall of uniform thickness, offers vertical grooving on the tube wall of hollow body, and the endoporus of hollow body is provided with rotating cam bit; After cam bit rotated, the tube wall that cam bit leans hollow body was opened the head elasticity of shop bolt.
