The utility model discloses can realize carrying out quick clamping with fixed to spherical spacer, it is fixed reliable, make things convenient for grinding equipment to spherical spacer's finish machining, improve work efficiency.
Description
Technical field
The utility model relates to a kind of fixture, is specifically related to a kind of spherical pad spherical outside surface clamp.
Background technology
Spherical pad is a kind of annular circle body with inside and outside spherical surface, the key of spherical pad is its sphere precision and fineness, in some critical components, the required precision of spherical pad is high, and the sphere of spherical pad needs could arrive required precision by grinding.The patent of invention of the patent No. 200810121605.0 that our company applied on October 11st, 2008, patent name " fixture for grinding spherical pad " solves the problems referred to above preferably, but shortcoming be for some not by the spherical pad of magnetic absorption (as brass material, powdered metallurgical material), just have no idea to utilize above-mentioned patented technology to implement grinding.For this, our company have employed multiple solution afterwards, and devise multiple clamp, but be from the endoporus of spherical pad, spherical pad is clamped substantially, although also devise the clamp clamped spherical pad from the excircle of spherical pad, the such as patent No. 201310354939.3 of application on August 15th, 2013, the patent of patent name " fixture of spherical pad and grinding spherical pad ", but it is obviously inadequate to the clamping dynamics of spherical pad, spherical pad easily throws away in grinding process, there is very big potential safety hazard.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide one can realize carrying out quick-clamping to spherical pad and fixing, fixing reliable, facilitate equipment for grinding to the fine finishining of spherical pad, the spherical pad spherical outside surface clamp of increasing work efficiency.
The utility model is implemented by the following technical programs:
Spherical pad spherical outside surface clamp, comprise the ring flange and chuck that are fixedly connected with, chuck has the spherical arc identical with spherical pad Internal Spherical Surface curvature, chuck spherical arc is provided with multiple alignment pin, the axis of alignment pin is by chuck sphere centre and perpendicular to the rotation of fixture, the external diameter of alignment pin and the diameter of bore of spherical pad match, it is characterized in that: alignment pin both sides are provided with left and right clamp, chuck spherical arc is provided with the left and right cavity corresponding with left and right clamp, left clamp is actively installed in left cavity, right clamp is actively installed in right cavity, the head of left and right clamp exceeds chuck spherical arc, chuck end face outside is fixedly connected with blind flange, blind flange end face outside is provided with adjustment screw, adjustment screw is rotated and is located on blind flange, collet interior between the cavity of left and right is provided with through hole and passes by adjustment screw activity, adjustment screw is provided with left hand thread and right-handed thread, left hand thread is threaded with left clamp, right-handed thread is threaded with right clamp.
The inner portion of left and right clamp has the negative camber mated with spherical pad cylindrical.
After adopting technique scheme, when grinding spherical pad, spherical pad is placed on the spherical arc of chuck, spherical pad carries out Internal hole positioning by alignment pin, then adjustment screw is rotated, left and right clamp is moved towards direction close to each other, so left and right clamp can clamp spherical pad from the excircle of spherical pad simultaneously, clamping great efforts, make fixing reliable on chuck spherical arc of spherical pad, so, spherical pad just not easily throws away in grinding process, eliminate safe hidden trouble, guarantee work safety.
Accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in the figure, spherical pad spherical outside surface clamp of the present utility model, comprise the ring flange 13 and chuck 1 that are fixedly connected with, chuck 1 has the spherical arc identical with spherical pad 7 Internal Spherical Surface curvature, chuck 1 spherical arc is provided with the number of four alignment pin 6(alignment pins can according to actual arrangement), the axis 5 of alignment pin 6 is by chuck 1 sphere centre and perpendicular to the rotation 12 of fixture, the external diameter of alignment pin 6 and the diameter of bore of spherical pad 7 match, alignment pin 6 both sides are provided with left clamp 4 and right clamp 9, chuck 1 spherical arc is provided with the left cavity 3 corresponding with left and right clamp and right cavity 10, left clamp 4 is actively installed in left cavity 3, right clamp 9 is actively installed in right cavity 10, the head of left and right clamp exceeds chuck 1 spherical arc, the inner portion of left and right clamp has the negative camber mated with spherical pad 7 cylindrical, chuck 1 end face outside is fixedly connected with blind flange 11, blind flange 11 end face outside is provided with adjustment screw 2, adjustment screw 2 is rotated and is located on blind flange 11, chuck 1 inside between the cavity of left and right is provided with through hole 8 allows adjustment screw 2 activity pass, adjustment screw 2 is provided with left hand thread 21 and right-handed thread 22, left hand thread 21 is threaded with left clamp 4, right-handed thread 22 is threaded with right clamp 9.
When grinding spherical pad, spherical pad 7 is placed on the spherical arc of chuck 1, spherical pad 7 carries out Internal hole positioning by alignment pin 6, then adjustment screw 2 is rotated, left clamp 4 and right clamp 9 are moved towards direction close to each other, so left and right clamp can clamp spherical pad 7 from the excircle of spherical pad 7 simultaneously, clamping great efforts, make spherical pad 7 fixing reliably on chuck 1 spherical arc, guarantee safety when grinding works.
