Description

Cylindrical Workpiece Slicing Fixture for Wire Cutting

technical field

The utility model relates to a fixture, in particular to a cylindrical workpiece slicing fixture for wire cutting.

Background technique

At present, there are mainly two types of common workpiece fixing methods for WEDM machine tools.

Further: the upper clamping body and the lower clamping body are arc panels.

Further: step grooves are provided on the inner walls of the upper clamp body and the lower clamp body.

Further: The lock nut is located on the upper or lower part of the positioning ear.

Compared with the prior art, the technical effects of the utility model include:

The utility model is suitable for fixing large cylindrical non-magnetic workpieces, which improves the cutting precision and processing quality. Use the fixed threaded rod and the fixed nut located in the card slot of the wire cutting machine table to cooperate with the fixed fixture body, and fix the workpiece in the fixture with the help of clamping bolts. During the cutting process, the contact surface between the workpiece and the fixture body can be reduced as much as possible. To ensure that the workpiece is firmly clamped, the clamped part of the workpiece is reduced, the root of the workpiece is cut completely, and the waste of workpiece materials is reduced. At the same time, the step groove used for workpiece positioning can provide a support platform for the workpiece during the assembly process to ensure that the workpiece is parallel to the fixture. In addition, the fixed thread rod and the positioning bolt cooperate with each other, on the one hand, the fixture can be firmly fixed on the workbench; on the other hand, the parallelism between the cutting end surface of the workpiece and the molybdenum wire can be adjusted to improve the cutting accuracy and ensure the cutting quality.

The utility model has the advantages of simple disassembly and assembly, convenience and practicality, especially strong practicability for slicing cylindrical workpieces, and can be popularized and used as a general fixture.
