Abstract

A composite tool comprises an integral hilt. A small-diameter seaming tool is mounted at the front end of the integral hilt, a large-diameter seaming tool is mounted behind the small-diameter seaming tool, and a boring tool is mounted behind the large-diameter seaming tool, and the small-diameter seaming tool and the large-diameter seaming tool are inserted in a hilt groove at the front end of the integral hilt by seaming tool hilts. A toolbar of the boring tool is square, is inserted in an oblique square hole which is arranged on the integral hilt, matches with the toolbar of the boring tool and is fixed both radially and axially by a screw. Three holes with the different diameters and the same center line are often required to be machined when a shell of a sewing machine is machined, the small-diameter hole is arranged at the front, the large-diameter hole is disposed on the rear, at the moment, the three holes can be machined and formed at one step by the aid of the composite tool, and the composite tool can also be provided with one tool so as to be used for machining one hole at one step.

Description

A kind of compound tool

Technical field

Present technique relates to mechanical processing industry, particularly a kind of compound tool of the digital control processing of sewing machine housing.

Background technology

At present the processing sewing machine housing has spot-facing processing technology, bore hole processing technology in the conventional process flow, and existing process using three is cutter, with separate machined alone after three tool changing.Taken lathe and used cutter spacing, working (machining) efficiency is not high.

Summary of the invention

To separate machined alone after above-mentioned three tool changing.Take lathe and used cutter spacing, the shortcoming that working (machining) efficiency is not high, the utility model has designed cutter again.

This compound tool comprises a whole handle of a knife, it is characterized in that, at the front end of whole handle of a knife, the path countersink is installed, and at the path countersink big footpath countersink is installed at the back, and countersink is equipped with boring cutter at the back in big footpath.

The path countersink is to be inserted in the handle of a knife groove of whole handle of a knife front end through the countersink handle of a knife with big footpath countersink.Can set up very easily or take off.

The knife bar of boring cutter is square, is inserted in the oblique square hole that matches with knife bar boring cutter on the whole handle of a knife, on radial and axial, all has screw to fix.

In the processing of sewing machine housing; Need process three different holes of diameter of same center line through regular meeting; Small diameter bore in front; At this moment large diameter hole just can utilize three holes of this compound tool time processing moulding in the back, and hole of a cutter time processing also can only be installed in this compound tool.

The utility model has made up boring cutter, large and small countersink according to processing housing processing actual conditions on a handle of a knife, accomplish former three simultaneously the work of cutter completion, has reduced the time of lathe tool changing, has improved working (machining) efficiency.

Description of drawings

Fig. 1 is cutter structure figure

Among the figure, 1, the path countersink, 2, big footpath countersink, 3, boring cutter, 4, whole handle of a knife.

The specific embodiment

In conjunction with Fig. 1, this compound tool comprises a whole handle of a knife 4, at the front end of whole handle of a knife 4, path countersink 1 is installed, and in path countersink 1 back big footpath countersink 2 is installed, and countersink 2 back are equipped with boring cutter 3 in big footpath.

Path countersink 2 is to be inserted in the handle of a knife groove of whole handle of a knife 4 front ends through the countersink handle of a knife with big footpath countersink 3.Can set up very easily or take off.

The knife bar of boring cutter 3 is square, is inserted in the oblique square hole that the knife bar with boring cutter 3 on the whole handle of a knife 4 matches, and on radial and axial, all has screw to fix.

Claims
