Description

Multi-station numerical control machining fast-assembling clamp

Technical Field

The utility model belongs to the technical field of the machine tool clamp, especially, relate to a multistation numerical control processing fast-assembling anchor clamps.

Background

As is known to all, the clamping of a rectangular solid part by flat tongs or other special fixtures is the positioning clamping of a single part, the rapid clamping of a plurality of parts cannot be realized, and the clamping of the flat tongs or other special fixtures has upward component force, which easily causes the inclination of the part clamping.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a multistation numerical control processing fast-assembling anchor clamps has solved the quick clamping of multistation of cuboid class part and has been processed the technical problem that the part easily inclines.

The technical scheme of the utility model be, a multistation numerical control processing fast-assembling anchor clamps includes anchor clamps main part, tapering compact heap, elasticity bracer and housing screw.

The center of the upper end of the clamp main body is provided with two stepped grooves which are positioned at two ends of the clamp main body, and the bottom surface of the top end groove of each stepped groove is provided with 2 part positioning surfaces;

the elastic supporting block is of a U-shaped structure, the profile of the cross section of the inner side of the upper end of the U-shaped structure is conical, the lower end of the elastic supporting block is inserted into a stepped groove bottom groove of the fixture main body, the upper end of the elastic supporting block extends out of the upper end of the bottom groove, the small end of the taper pressing block is inserted into the elastic supporting block, and a pressing screw is sequentially screwed into a center hole of the taper pressing block, a center hole of the bottom of the elastic supporting block and a center hole of a bottom groove.

The right angle department of the inside surface of two ladder grooves sets up the right angle hole of stepping down on the anchor clamps main part.

The utility model has the advantages that the utility model effectively solves the multi-station quick clamping problem of cuboid parts; the problem of stress inclination under the action of clamping force of the cuboid parts is effectively solved; the utility model discloses the clamping mode of fast-assembling anchor clamps then adopts tapering compact heap cooperation elasticity bracer, and the clamp force is decurrent effect mode, clamping location part safe and reliable, the precision is high.

Detailed Description

The technical solution of the present invention is further described in detail below with reference to the drawings.

As shown in fig. 1, fig. 2, fig. 3 and fig. 4, the utility model relates to a multistation numerical control processing fast-assembling anchor clamps includes anchor clamps main part 1, tapering compact heap 2, elasticity bracer 3 and housing screw 4.

Two stepped grooves are formed in the center of the upper end of the clamp body 1 and are located at two ends of the clamp body 1. The bottom surface of the top groove of the stepped groove is 2 part positioning surfaces. And right-angle yielding holes are formed in the right-angle positions of the inner side surfaces of the two stepped grooves. The bottom of the stepped groove is provided with a threaded hole. The bottom groove of the stepped groove forms an elastic support block abdicating groove. The centers of the outer edges of the two ends of the bottom of the clamp body 1 are respectively provided with a U-shaped pressing groove. The clamp body 1 is fixed on a numerical control machine tool workbench through bolts and outer edge-shaped pressing grooves at two ends of the bottom.

The taper pressing block 2 is provided with a thread center hole. The compression screw 4 is screwed in a thread central hole of the taper compression block 2, and the taper compression block 2 is moved by rotating the compression screw 4.

The elastic supporting block 3 is of a U-shaped structure, and the cross section outline of the inner side of the upper end of the U shape is conical. The center of the bottom of the elastic supporting block 3 is provided with a screw through hole, and the taper pressing block 2 is driven to move downwards by rotating the pressing screw 4 so as to realize the opening of the upper end of the elastic supporting block.

The lower end of the elastic supporting block 3 is inserted into the bottom groove of the stepped groove of the clamp body 1, and the upper end of the elastic supporting block 3 extends out of the upper end of the bottom groove. The small end of the taper pressing block 2 is inserted into the elastic supporting block 3, and the pressing screw 4 is sequentially screwed into the center hole of the taper pressing block 2, the center hole of the bottom of the elastic supporting block 3 and the center hole of the bottom groove of the clamp main body 1 from top to bottom.

The clamp body 1, the taper pressing block 2 and the elastic supporting block 3 are made of 40Cr alloy steel, and the pressing screw 4 and the elastic supporting block 3 are made of 45# medium carbon steel.

The flatness of each surface of the clamp main body is less than 0.01mm, and the parallelism is less than 0.01 mm.

The hardness of the clamp main body 1, the elastic supporting block 3, the taper pressing block 2 and the pressing screw 4 is 35 HRC-40 HRC.

The working principle of the utility model is that 4 processed workpieces are respectively placed on 4 part positioning surfaces of two stepped grooves. The taper pressing block 2 is driven to move downwards through the rotary pressing screw 4, so that the upper end of the elastic supporting block 3 is propped outwards, and the clamping effect on a plurality of machined parts is finally realized by matching with the stepped groove side face of the clamp main body 1.
