Abstract

The utility model pertains to the grinding technology, which relates to a flat grinding tool of small parts. The flat grinding tool includes a flat grinding bottom board 1, which is characterized in that a part clamping mechanism is composed of a supporting block 2, a pressing mechanism and a three-jaw clamp 5, the supporting block 2 is a hexahedron, a V-shaped groove 6 is arranged on one surface, the V-shaped groove 6 is perpendicular to the bottom surface 7 of the supporting block 2, and the three-jaw clamp 5 is fixed in the V-shaped groove 6 by the pressing mechanism. The flat grinding tool solves the difficult problem that the small parts are difficult to be clamped, which can stably clamp the parts, ensure the flatness and the size precision of the grinding of the parts and meet the performance requirements of a fault detection device after assembly.

Description

The flat instrument that grinds of micro parts

Technical field

The utility model belongs to grinding technique, relates to the flat instrument that grinds of a kind of micro parts.

Background technology

In the tracer that uses on certain type aircraft actuator, have and in assembling process, to carry out the button and the adjustment pad of facing-up one by one according to tolerance.These parts small-sized is difficult to clamping.Be that hand-held part carries out facing-up at present, its shortcoming is: the clamping instability, influence flatness and dimensional accuracy that part grinds, and do not satisfy the performance requirement of tracer after causing assembling.

Summary of the invention

The purpose of this utility model is: propose the flat instrument that grinds of micro parts of a kind of energy stable holding part, the flatness of guaranteeing the part grinding and dimensional accuracy, with the performance requirement of tracer after the satisfied assembling.

The technical solution of the utility model is: the flat instrument that grinds of micro parts, comprise a flat base plate 1 that grinds, it is characterized in that, be positioned at the flat part clamping device on the base plate 1, that form by back-up block 2, hold-down mechanism and three-jaw chuck 5 that grinds by one, back-up block 2 is a hexahedron, a V-shaped groove 6 is arranged on one face, and this V-shaped groove 6 is vertical with the bottom surface 7 of back-up block 2, by hold-down mechanism three-jaw chuck 5 is fixed in the V-shaped groove 6.

The utility model has the advantages that: the utility model has solved the difficult problem that micro parts is difficult to clamping, and energy stable holding part has been guaranteed flatness and dimensional accuracy that part grinds, has satisfied the performance requirement of assembling back tracer.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the vertical view of Fig. 1.

The specific embodiment

Below the utility model is described in further details.Referring to Fig. 1,2, the flat instrument that grinds of micro parts, comprise a flat base plate 1 that grinds, it is characterized in that, by one be positioned at flat grind on the base plate 1, by the part clamping device that back-up block 2, hold-down mechanism and three-jaw chuck 5 are formed, back-up block 2 is a hexahedron, and a V-shaped groove 6 is arranged on one face, this V-shaped groove 6 is vertical with the bottom surface 7 of back-up block 2, by hold-down mechanism three-jaw chuck 5 is fixed in the V-shaped groove 6.

Said hold-down mechanism is one of following structure:

(1) hold-down mechanism is made up of vertical compression plate 3 and two screws 4 that two ends have through hole, in the both sides of V-shaped groove 6 screwed hole is arranged respectively, and two screws 4 are screwed in respectively in above-mentioned two screwed holes after passing through hole on the vertical compression plate 3;

(2) hold-down mechanism has bent clamp and two screws 4 through hole, that the centre has a semi arch by two ends and forms, and in the both sides of V-shaped groove 6 screwed hole is arranged respectively, and two screws 4 are screwed in respectively in above-mentioned two screwed holes after passing through hole on the bent clamp;

(3) hold-down mechanism has hinge pressing plate and screw 4 that pan, the other end have through hole by an end and forms, side at V-shaped groove 6 has the lug that has pan, a hinge axis is inserted in the pan of hold-down mechanism and V-shaped groove 6 lugs, opposite side at V-shaped groove 6 has a screwed hole, and screw 4 is screwed in the above-mentioned screwed hole after passing through hole on the hinge pressing plate.

Using method of the present utility model is: micro parts is put into three-jaw chuck 5 clampings and locking, there is the three-jaw chuck 5 of micro parts to put into the V-shaped groove 6 of back-up block 2 clamping, adjust the height of three-jaw chuck 5 up and down, make the flat surface of grinding of needs of micro parts and peaceful bottom surface 7 contacts of grinding base plate 1 in bottom surface of back-up block 2.Tighten two screws 4, make pressing plate 3 compress three-jaw chuck 5.Grind on the base plate 1 flat, the tiling polishing paper, hand-held supports piece 2 is put down and is ground by " 8 font " method on polishing paper.Flat grind finish after, unclamp two screws 4, remove pressing plate 3, take out three-jaw chuck 5, unclamp clamping and take out micro parts and get final product.
