Description

Clamp for polishing bar slitting knife

Technical Field

The utility model relates to the technical field of clamps, in particular to a clamp for polishing a bar slitting knife.

Background

As shown in fig. 4, the bar parting knife 8 is made of steel, the end of the knife body is embedded with a knife head 9 made of alloy, and the knife head 9 is easy to wear after a long time, and needs to be polished to form a new cutting edge. Because of the angle of inclination of the facets to their side walls, it is desirable to tilt the blade to maintain the facets level for ease of sharpening, and a special fixture is required to stably load the splitting blade on the grinder bed for machining.

Disclosure of Invention

Based on the above, the utility model aims to provide the clamp for polishing the bar slitting knife, which can realize the inclined fixation of the knife body and is convenient for polishing the cutting edge.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a rod is cut sword and is polished and use anchor clamps, it includes fixing base and latch segment, has seted up the standing groove that the cross-section is trapezoidal on the fixing base, and the lateral wall slope of standing groove has erect the screw thread post on the tank bottom, thereby has seted up on the latch segment and has worn the shape hole to overlap to locate on the screw thread post, is equipped with the nut on the screw thread post, and the nut is spacing to the upper run of latch segment, cuts the sword and pastes on a lateral wall of leaning on the standing groove and make cutting edge machined surface level to tightly fix by the latch segment top.

Particularly, the bottom of the placing groove is provided with a limit groove, the limit groove is wedge-shaped, and the bottom of the dividing knife is sunk into the limit groove.

In particular, the locking blocks are provided as trapezoidal blocks which match the groove shape of the placement groove.

In particular, a plurality of locking blocks are arranged in the placing groove at intervals along the length direction.

In particular, the through-hole is a kidney-shaped hole extending in the width direction of the placement groove.

In conclusion, the clamp for polishing the bar slitting knife has the beneficial effects that the inclined clamping and fixing of the slitting knife are realized, so that the processing surface of the cutting edge is horizontal, the polishing and processing are convenient, the cost is low, the clamping effect is good, and the use requirement is met.
