The advantages are that: the utility model discloses the replacement is comparatively convenient, use cost is comparatively cheap.
Description
Technical Field
The utility model belongs to the technical field of metal work piece positioning tool, especially, relate to a but wear-resisting flat tongs of substitution.
Background
At present, in the field of machine manufacturing, a machine tool is the most common instrument in the field of hardware, and a workpiece is positioned on a punch press or a grinding machine through flat tongs; the binding clip and the binding clip of the existing flat tongs are mostly integrally formed by iron materials, however, the flat tongs need larger pressure when clamping a workpiece, and the end surfaces of the flat tongs are easily abraded by extrusion between metals, so that the existing flat tongs need to be entirely replaced after being abraded, and the use cost is higher; there is a need for improvement.
Disclosure of Invention
The utility model aims at the not enough of above-mentioned prior art existence, provide a but wear-resisting flat-nose pliers of substitution, it has the comparatively convenient, the comparatively cheap characteristics of use cost of replacement.
In order to realize the purpose, the utility model discloses the technical scheme who adopts is: a replaceable wear-resistant flat tongs comprises a tong seat, a tong head, a tong block, a ball screw and a hand crank, wherein the tong head is fixedly arranged on the tong seat and is matched with the tong block in an opening and closing manner; the hand crank is fixedly connected to the end part of the ball screw; the clamp comprises a clamp head and a clamp block, wherein the clamp head is arranged on the clamp block, the clamp block is arranged on the clamp head, and the clamp block is arranged on the clamp head.
The clamp plate is provided with a convex part, and the end surface of the convex part is flush with the inner end surfaces of the clamp head and the clamp block respectively.
The outer end face of the nipper is plated with a wear-resistant coating.
After the structure is adopted, compared with the prior art, the utility model the advantage that has is: the nipper of the utility model can be disassembled on the nipper head and the nipper block, so that the nipper can be replaced after being worn, thus greatly saving the use cost; the wear-resistant coating on the outer end face of the nipper can improve the wear resistance and prolong the service life.

Detailed Description
The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.
Examples, see fig. 1 and 2: a replaceable wear-resistant flat tongs comprises a tongs base 10, tongs heads 11, tongs blocks 12, a ball screw 13, a hand crank 14, a nut base 16 and tongs plates 18, wherein a workbench is arranged on the tongs base 10, and the tongs heads 11 and the tongs blocks 12 are both positioned on the workbench and are in open-close fit with each other. The clamp base 10 is provided with a guide rail 15, the bottom of the clamp block 12 is provided with a sliding groove, and the sliding groove is arranged on the guide rail 15 in a sliding way, so that the clamp block 12 can slide on the guide rail 15 back and forth. The bottom of the clamp block 12 is provided with a nut seat 16, the ball screw 13 is positioned on the clamp seat 10 and is in threaded connection with the nut seat 16, and the hand crank 14 is fixedly connected with the end part of the ball screw 13; when the pliers are used, the ball screw 13 can be rotated by rotating the hand crank 14, so that the nut seat 16 can move forward or backward to drive the pliers block 12 to move. Clamping grooves are formed in the opposite end faces of the clamp head 11 and the clamp block 12, the clamping grooves are of an open structure, a clamp plate 17 is clamped in the clamping grooves, and the clamp plate 17 is respectively positioned in the clamp head 11 and the clamp block 12 through bolts 18; through the structure, the nipper 17 can be disassembled on the nipper head 11 and the nipper block 12, so that the nipper 17 can be replaced after being worn, and the use cost can be greatly saved. The clamp plate 17 is provided with a convex part, the end surface of the convex part is flush with the inner end surfaces of the clamp head 11 and the clamp block 12 respectively, and the structural arrangement can enable the positioning of the workpiece to be more stable. The outer end face of the nipper 17 is plated with a wear-resistant coating, which can improve the wear resistance and prolong the service life.
