Description

Part wire-electrode cutting frock

Technical Field

The utility model relates to a cutting frock, concretely relates to part wire-electrode cutting frock.

Background

The complicated part shape often can increase the processing degree of difficulty of part, when the surface to hollow tubular part need be carried out line cutting, how to fix the part is the key in the course of working, and tubular part often can take place to rotate in the course of working for it is more difficult to the fixed of part.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a part wire-electrode cutting tool which can limit and fix a hollow tubular part so as to carry out wire-electrode cutting processing; the technical scheme is as follows:

a part linear cutting tool comprises a base and a mandrel, wherein a limiting mechanism for preventing the mandrel from rotating is arranged on the base, the base is detachably connected with the mandrel, and the limiting mechanism limits the mandrel and a part in a direction perpendicular to the central line of the mandrel; the part cup joints on the dabber, stop gear also can carry out spacingly to the part when carrying out spacing to the dabber.

Preferably, the upper end of the base is provided with a through hole, and the mandrel is matched and connected with the through hole and is fixed through a fastener.

Preferably, the through-hole is a counter bore, one end of the mandrel is provided with a flange which is connected with the counter bore in a matched mode, the other end of the mandrel is provided with threads, the mandrel penetrates through the counter bore in the base, and the other end of the mandrel is fixed through a nut.

Preferably, the limiting mechanism comprises a limiting hole and a limiting pin, the base is provided with a first limiting hole, the central line of the first limiting hole is perpendicular to the central line of the through hole, the mandrel is provided with a second limiting hole, the central line of the second limiting hole is perpendicular to the central line of the mandrel, and the limiting pin is connected with the first limiting hole and the second limiting hole in a matched mode so as to limit the mandrel.

A core shaft penetrates through a through hole formed in the base, a part is sleeved on the core shaft, and the part is fixed through a nut; the stop pin passes first spacing hole on the base hole on the part, the spacing hole of spindle second to it is spacing to carry out the rotation of part in the process of working to the part.

The utility model has the advantages that: can install spacingly to hollow tubular part fast to wait for wire-electrode cutting processing.
