Description

A kind of screwdriver bit process tool

Technical field

The utility model relates to a kind of cutter more particularly to a kind of screwdriver bit process tools, belong to screwdriver bit processing technology neck Domain.

Background technique

Existing screwdriver bit process tool generally using carbide bit is welded on tool steel body, is ground, knife After tool abrasion, needing to grind again, change since cutter grinds rear size, when processing, need to be again to size, and centering is cumbersome, Influence processing efficiency.

Utility model content

The utility model in view of the above-mentioned deficiencies in the prior art, provides a kind of screwdriver bit process tool.

The technical solution that the utility model solves above-mentioned technical problem is as follows:

A kind of screwdriver bit process tool, including cutter body, the cutter body include knife handle, transition face and knife bar, described Knife handle includes the fixed plane in side and clamping position face, and notch is provided with inside the knife bar, is equipped with replaceable blade inside the notch Piece, the blade are equipped with the screw hole being used cooperatively with fastening screw, are used for fixed blade.

Preferably, the knife handle of cutter body, transition face and knife bar are whole cut.

Preferably, the knife handle and knife bar are cylindrical structure, and the section that the diameter of section of the knife handle is greater than knife bar is straight Diameter.

Preferably, the transition face is that one end round table-like and that transition face diameter of section is big connects knife handle, and diameter of section is small One end connect knife bar.

Preferably, the knife handle is cylindrical structure, and there are two symmetrical plane, institutes for the knife handle cutting of the cylindrical structure Stating two symmetrical planes cut into is the fixed plane in side, and non-cutting surface is clamping position face.

Preferably, the blade is equipped with eight work edges, and the screwdriver bit of PH and PZ different model can be processed.

Preferably, between the notch and blade there are gap, for facilitate blade replacement and work edge rotation it is solid It is fixed.

Preferably, the screw hole is blind hole.

Compared with prior art, the utility model has the beneficial effects that blade exchange is more convenient, blade has eight works Make sword, the screwdriver bit of PH and PZ different model can be processed, utilization rate is higher, and cutter does not need frequently to position, machining accuracy and efficiency It is higher.

Specific embodiment

The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical It is novel, it is not intended to limit the scope of the utility model.

A kind of screwdriver bit process tool, including cutter body, it is characterised in that: the cutter body includes knife handle 1, transition face 4 and knife bar 5, the knife handle 1 includes the fixed plane 2 in side and clamping position face 3, is provided with notch 6, the slot inside the knife bar 5 6 inside of mouth is equipped with changeable blade 7, and the blade 7 is equipped with the screw hole 9 being used cooperatively with fastening screw 8, is used for fixing cutter Piece 7.

Knife handle 1, transition face 4 and the knife bar 5 of cutter body are whole cut.

The knife handle 1 and knife bar 5 are cylindrical structure, and the diameter of section of the knife handle 1 is greater than the diameter of section of knife bar 5.

The transition face 4 is that round table-like and one end that 4 diameter of section of transition face is big connects knife handle 1, diameter of section it is small one End connection knife bar 5.

The knife handle 1 is cylindrical structure, and there are two symmetrical planes for the cutting of knife handle 1 of the cylindrical structure, described to cut Two symmetrical planes being whittled into are the fixed plane 2 in side, and non-cutting surface is clamping position face 3.

The blade 7 is equipped with eight work edges, and the screwdriver bit of PH and PZ different model can be processed.

There are gap between the notch 6 and blade 7, replacement and the rotation of work edge for facilitating blade 7 are fixed.

The screw hole 9 is blind hole.

Embodiment 1

When processing screwdriver bit, knife handle 1 is fixed on by matching used machine by the fixed plane 2 in side and clamping position face 3 On bed, suitable work edge is selected for different types of screwdriver bit, screwing fastening screw 8 makes 7 fixation of blade that can start to work, When precision is not high due to abrasion for blade 7, the more allowing blade replacement 7 of fastening screw 8 is unclamped, without again to size centering.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model Within the scope of shield.
