Abstract

The invention relates to a clamp for manufacturing a needle of a cube-corner prism, comprising a substrate, a base and a face cover. A platform body is arranged at the center of the substrate; a through hole is respectively arranged at the centers of the base and the face cover; the base is installed on the substrate; the face cover is positioned above the base; the platform body passes through the through holes of the face cover and the base simultaneously; the face cover, the base and a column body are fixed together; the base is a circular conical surface; concave grooves are arranged on the surface of the base at intervals along radius direction; both ends of the groove respectively extend along the surface of the base; the back face of face cover is also a circular conical surface; concave grooves are arranged on the back face of the face cover at intervals along radius direction; both ends of the groove respectively extend along the back face of the back face; and the grooves at the surface of the base correspond to the grooves at the back face of the face cover one by one to form strips of spaces for clamping the needles of regular hexagonal prisms. The clamp has simple assembly and firmly fixes needles, and the needles have good polishing effect and unified standard, thereby the invention greatly improves the polishing efficiency of needles, reduces the labor strength of workers, and has high automation degree.

Description

Be used to make the anchor clamps of the pin of prism of corner cube

Technical field

The present invention relates to the anchor clamps that a kind of pin that is used to make prism of corner cube is used, this kind pyramid rib border is used in the Reflex Reflector as reflection source.

Background technology

What make prism of corner cube in the Reflex Reflector is positive hexagonal prism with pin, the one end must be polished into triangular pyramid, now six prisms being processed into the prism of corner cube pin is one one grinding and grinding, speed is slow, the specification of every pin all has difference, and the prism of corner cube reflecting effect that this pin is made is difficult to reach specified standard.

Summary of the invention

Therefore, the pin that the object of the present invention is to provide a kind of mechanization degree height, grinds meets the requirements, uniform specification, clamping are firm, prevent that pin vibration and being used to of rotating from making the anchor clamps of the pin of prism of corner cube.

Therefore, purpose of the present invention realizes by the following technical solutions:

A kind of anchor clamps that are used to make the pin of prism of corner cube, comprise matrix, base and cover, matrix central authorities are provided with a cylinder, base and cover central authorities are respectively equipped with a through hole, base is installed on the matrix, and wherein cylinder is upward through base plate through holes, and cover is located in the base top, cylinder passes the cover through hole simultaneously, and cover, base and cylinder three are fixed together;

Susceptor surface concaves, and forms a taper seat, and susceptor surface is interval with the groove of indent along radial direction, and extend along susceptor surface respectively at the groove two ends;

The cover back side also forms a taper seat to evagination, and the cover back side is interval with the groove of indent along radial direction, and extend along the cover back side respectively at the groove two ends;

When the described cover back side and susceptor surface were superimposed, susceptor surface groove and cover back side groove be corresponding matching one by one up and down, formed the space of the positive hexagonal prism pin of a rule clamping.

Can be fixed on many pins on these anchor clamps by these anchor clamps, many faller gills become a circle, and the end of the pin of needs polishing is exposed at the anchor clamps outside, after pin is simultaneously polished, unclamp anchor clamps, and all pins are rotated the polishing again of 120 degree in the same way.

It is further perfect that technique scheme also can be made down skill:

The profile of described base and cover is in the form of annular discs, and described cylinder is a cylinder, can guarantee the polishing effect unanimity of many pins.If it is also passable that discoid anchor clamps are made into regular polygon, just anchor clamps are processed the cumbersome while and can't be allowed the spacing distance of every pin equate, cause the grinding effect can be not good enough.

Two inclined-plane intersections in the described susceptor surface groove are provided with a little groove more inwards, and this little groove length is suitable with the susceptor surface groove; Two inclined-plane intersections in the groove of the described cover back side are provided with a little groove more inwards; this little groove length is suitable with cover back side groove; in susceptor surface groove and cover surface groove, establish a little groove again; mainly be in order not allow the corner limit and the groove of pin rub; the protection pin simultaneously also is to cooperate better between pin and the groove in order to allow.The bearing of trend in the space that described susceptor surface groove and cover surface groove form altogether is vertical with the damaged surface of intersecting with it.

Structural design advantages of simple of the present invention, the anchor clamps assembling is simple, and pin is fixed, can not vibrate also after fixing and can not rotate, and the polishing of pin is effective, and standard is unified, has improved the grinding efficiency of pin greatly, has reduced working strength of workers, the automaticity height.

The specific embodiment

The invention will be further described below in conjunction with drawings and Examples.

Embodiment, in conjunction with Fig. 1 to Fig. 7, a kind of anchor clamps that are used to make the pin of prism of corner cube, comprise matrix 1, base 2 and cover 3, be formed with an outstanding cylinder 4 on matrix 1 mediad, base 2 and cover 3 central authorities are respectively equipped with a through

hole

5,6, base 2 is installed on the matrix 1 by screw 7, wherein cylinder 4 is upward through base plate through holes 5, cover 3 is located in base 2 tops, and cylinder 4 passes cover through hole 6 simultaneously, cover 3, base 2 and cylinder 4 threes are by screw 8 (see figure 1) that is fixed together, cylinder 4 is multistage cylinder, matrix 1, base 2 and cover 3 profiles are in the form of annular discs.

Base 2 surfaces concave, form a taper seat, base 2 surfaces are interval with the groove 9 of indent along radial direction, and extend along susceptor surface respectively at groove 9 two ends, two inclined-plane intersections in the susceptor surface groove 9 are provided with a little groove 10 more inwards, and these little groove 10 length are suitable with groove 9.

Cover 3 back sides are to evagination, also form a taper seat, cover 3 back sides are interval with the groove 11 of indent along radial direction, extend along the cover back side respectively at groove 11 two ends, two inclined-plane intersections in the cover back side groove 11 are provided with a little groove 12 more inwards, and these little groove 12 length are suitable with groove 11.

Described cover 3 back sides and base 2 are surperficial when superimposed, susceptor surface groove 9 and cover back side groove 11 be corresponding matching one by one up and down, form space 14 (see figure 2)s of the positive hexagonal prism pin 13 of a rule clamping, the bearing of trend in space 14 is vertical with cylinder 4 surfaces that intersect with it.
