Abstract

The utility model relates to an alloy cutter adaptable to various hole diameters. The alloy cutter comprises a handle (1), a sleeve (2), a lock screw (4) and an alloy cutter body, wherein the lower end of the handle (1) is fixedly connected with the middle of the upper surface of the sleeve (2), a laterally through hole is formed in the sleeve (2), a cutter bar (3) penetrates through the hole, the lock screw (4) penetrates through a screw hole formed in the lower part of the sleeve (2) to be propped against the lower surface of the cutter bar (3), a downward bend is arranged at one end of the cutter bar (3), and a blade (5) is arranged at the lower part of the downward bend. According to the alloy cutter, the blade on the cutter bar can be controlled through combination of the square hole of the sleeve and the lock screw, and the requirement for machining of workpiece holes with different hole diameters can be met.

Description

A kind of alloy knife that adapts to multiple aperture

[technical field]

The utility model relates to a kind of alloy knife, especially relates to a kind of alloy knife that adapts to multiple aperture.

[background technology]

In mechanical processing industry, for needs, installing hole or through hole workpiece are set, first use gas cutting to form the blank in hole, then grinding processing is carried out in the hole being gone out for gas cutting on workpiece by the alloy knife on milling machine, namely utilize alloy cutter on workpiece, to need reciprocal feed, to smooth meeting of hole wall used or design requirement, especially larger hole, requires higher for tool precision; Existing way is first to use slightly smaller alloy knife to carry out initial stage grinding, then use accurately alloy knife to carry out accurate grinding, so not only the time is longer, and need use to overlap alloy knifes more, especially for while a plurality of holes of grinding on a workpiece, and a plurality of holes are while being divided into the grinding in multiple aperture, cutter will have tens covers.

[summary of the invention]

In order to overcome the deficiency in background technology, the utility model discloses a kind of alloy knife that adapts to multiple aperture, utilize the square opening of body just can control knife bar upper knife edge in conjunction with lock screw, can realize the different workpiece hole process requirements in aperture.

In order to realize described utility model object, the utility model adopts following technical scheme:

A kind of alloy knife that adapts to multiple aperture, comprise handle of a knife, body, lock screw and alloy knife, the lower end of handle of a knife is fixedly connected with the upper side of body middle part, on body, be provided with about one hole connecting, knife bar is through in described hole, after the screw that lock screw arranges through body bottom, withstand in the bottom surfaces of knife bar, in one end of described knife bar, be provided with downward bending, in the bottom of downward bending, be provided with blade.

The described alloy knife that adapts to multiple aperture, the hole that the left and right arranging on body connects is square opening, knife bar is set to square structure.

Owing to having adopted technique scheme, the utlity model has following beneficial effect:

The alloy knife that adapts to multiple aperture described in the utility model, by the square opening arranging on body, regulated the insertion depth of knife bar, then use lock screw fixedly knife bar just can form the processing needs of required aperture workpiece hole, realize the different workpiece hole process requirements in aperture; The utlity model has the advantages such as simple in structure, economic and practical.

[accompanying drawing explanation]

Fig. 1 is structural representation of the present utility model.

Fig. 2 is that the A of Fig. 1 is to view.

In figure: 1, handle of a knife; 2, body; 3, knife bar; 4, lock screw; 5, blade.

[specific embodiment]

Explanation the utility model that can be detailed by the following examples, open the purpose of this utility model is intended to protect all technological improvements within the scope of the utility model,

The alloy knife that adapts to multiple aperture described in 1 or 2 by reference to the accompanying drawings, comprise handle of a knife 1, body 2, lock screw 4 and alloy knife, the lower end of handle of a knife 1 is fixedly connected with the upper side middle part of body 2, on body 2, be provided with about one square opening connecting, square knife bar 3 is through in described hole, after the screw that lock screw 4 arranges through body 2 bottoms, withstand in the bottom surfaces of knife bar 3, in one end of described knife bar 3, be provided with downward bending, in the bottom of downward bending, be provided with blade 5.

Implement the alloy knife that adapts to multiple aperture described in the utility model, utilize the square opening arranging on body 2 to regulate the insertion depth of knife bar 3, by the knife bar 3 behind lock screw 4 location, just can form the processing needs of required aperture workpiece hole, when changing aperture, unclamp lock screw 4, again regulate knife bar 3 at the insertion depth of body 2, then by lock screw 4 location, just can realize the different workpiece hole process requirements in aperture; The utility model can shorten man-hour effectively, has saved the use amount of alloy knife.The utility model does not describe part in detail for prior art.
