A wire cutting machine with V-shaped positioning mode

Abstract

The invention discloses a linear cutter with a V-shaped positioning way and belongs to the technical field of linear cutting. The linear cutter comprises a machine frame, wherein a workbench is arranged on the machine frame; at least one clamp is arranged on the workbench; the clamp comprises a V-shaped block and a U-shaped clamp; an L-shaped section which is bent towards the center of the U-shaped clamp is arranged at each of the two free ends of the U-shaped clamp; a slide groove is formed in each of the two sides of the V-shaped block; the L-shaped sections of the U-shaped clamp are glidingly embedded in the slide grooves along the slide grooves; a threaded through hole is formed in the top of the U-shaped clamp; a bolt is arranged in the threaded through hole in a matching way; at least one flange is arranged on the surface of the workbench; a groove mated with the flange is formed in the bottom surface of the V-shaped block. By the bolt on the U-shaped clamp, a rod on the V-shaped block is tightly clamped, rods with different sizes can be tightly screwed by the bolt to push against the surfaces of the rods to be tightly clamped, and the U-shaped clamp can slide to the corresponding position to realize different clamping positions, so that processing is convenient to perform, the operation is simple and quick, and the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of wire cutting, in particular to a wire cutting machine with a V-shaped positioning method. Background technique [0002] Wire cutting is realized by using the erosion effect on the workpiece produced by the pulse discharge between the electrode wire and the two poles of the workpiece. During normal cutting, the electrode wire and the workpiece are in a non-contact state, and there is no cutting force. Therefore, the clamping of the workpiece in wire cutting generally only needs to consider the positioning of the workpiece, and the clamping in wire cutting is mainly to prevent the possible displacement of the workpiece under the action of external force. In the process of manual wire threading and waste removal for many times, it may collide with the workpiece and cause the workpiece to move. The vibration of the machine tool during cutting may also cause the position of the workpiece to change, so a certai...
