Description of the drawings:

FIG. 1 is a view of the overall structure of the present invention;

FIG. 2 is a schematic view of the structure of the gear and nut carrier of FIG. 1;

FIG. 3 is a schematic structural view of the lead screw of FIG. 1;

fig. 4 is a schematic structural view of the body of fig. 1.

The specific implementation mode is as follows:

as shown in fig. 1-4, a clamping device for grinding a metal test block comprises a main body 1, wherein the main body 1 comprises a transverse plate 1a, two ends of the transverse plate 1a are respectively provided with a vertical plate 1b, the vertical plates 1b are perpendicular to the transverse plate 1a, and the transverse plate 1a and the vertical plates 1b are of an integrated structure, so that the main body 1 is in a door-shaped structure.

Be equipped with spout 2 along the length direction of riser at every

riser

1b, 2 ascending central lines of spout width direction lie in with riser 1b width direction ascending central line one side, and be equipped with the interval between 2 ascending central lines of spout width direction and the riser 1b width direction ascending central line, and two central lines are parallel distribution. This divides the vertical plate 1b on both sides of the chute 2 into a large plate a having a large area and a small plate b having a small area.

Set up a roof 3, be equipped with a slider 3a of card income spout 2 respectively at roof 3 both ends, the welding has rack 4 on the lower surface of roof 3, rack 4 become vertical distribution with the lower surface of roof 3.

The blind hole a1 is arranged on the large plate surface a on one side of the lower sliding groove 2 of one vertical plate 1b, the threaded hole a2 is arranged on the large plate surface a on one side of the lower sliding groove 2 of the other vertical plate 1b, and the blind hole a1 and the threaded hole a2 are coaxially distributed.

The gear 6 is correspondingly matched with the rack 4, a round hole 6b which is coaxially distributed is formed in one end of the gear 6, key grooves 6d which are axially distributed are formed in the hole wall of the round hole 6b, a nut seat 6a which protrudes out of the wheel surface of the gear 6 is formed in the other end of the round hole 6b, the gear 6, the round hole 6b, the key grooves 6d and the nut seat 6a are of an integrated structure which is coaxially distributed, and threaded holes of the round hole and the nut seat are not communicated.

A rotating shaft 5 is arranged, one end of the rotating shaft 5 is a polished rod, a key which is correspondingly matched with the key groove 6d is arranged at the end part of the other end of the rotating shaft, and the key and the rotating shaft 5 are integrally formed. One end of the rotating shaft 5 is inserted into the blind hole a1, and the other end is inserted into the round hole 6b and fastened with the key groove 6d, so that the rotating shaft 5 and the gear 6 form synchronous rotating fit.

The screw rod 8 is arranged in the threaded hole a2 in a penetrating way, the front end part of the screw rod 8 is a section of polished rod part 8a, the polished rod part 8a is inserted into the nut seat 6a, and the length of the polished rod part 8a is lower than that of the threaded hole 6c in the nut seat 6 a.

The rear end of the screw rod 8 is positioned on the outer side of the vertical plate 1b, a through hole 8b is arranged on the end of the screw rod, a cross rod 7 capable of axially sliding along the through hole is arranged in the through hole in a penetrating mode, and the axis of the cross rod 7 and the rotating shaft 5 are vertically distributed. Limiting blocks 7a are further welded at two ends of the cross rod 7, and the cross rod 7 is prevented from being separated from the through hole through limiting of the limiting blocks 7 a.

The diameter of the gear 6 is smaller than the width of the large plate surface a of the vertical plate 1b on one side of the sliding groove 2, so that the outer circular surface of the gear 6 cannot extend out of the vertical plate 1 b.

The working process is as follows:

a metal test block is placed between the horizontal plate 1a and the top plate 3, and the polished surface of the metal test block extends out of the upper surfaces of the main body 1 and the top plate 3. And then the rack 4 is pushed, so that the top plate 3 clamps the metal test block, and the rotating shaft 5 and the gear 6 rotate along with the movement of the rack 4. And when the top plate 3 clamps the metal test block, one hand holds the gear 6, and the other hand starts to rotate the cross rod 7 to drive the screw rod 8 to rotate, so that the thread section of the screw rod 8 is screwed into the nut seat 6a until the screw rod is screwed.

And finally, when the polishing is carried out on sand paper or a grinding machine, the outer surface of the main body 1 is held by hands for polishing. The upper surface and the lower surface of the clamp can clamp the metal test block.
