Abstract
The utility model relates to a ground titanized spiral pointed machine screw tap which solves the technical problem that the screw tap is mounted on a machine tool difficultly in the prior art. The ground titanized spiral pointed machine screw tap comprises a body, wherein the body consists of a holding part and a tapping part; the holding part is arranged at the end part of the body; and the external diameter of the holding part is slightly less than that of the body.
Description
Technical field
The utility model belongs to the conventional tool technical field of machining internal thread, refers in particular to a kind of titanizing spiral shell point machine tap that grinds.
Background technology
Screw tap is extensively used as the conventional tool of machining internal thread.At present, spiral shell point machine tap is mainly by body, and this body is mainly formed by clamping part and tapping section, and the maximum outside diameter of this clamping part is consistent with the external diameter of tapping section, causes this screw tap to be not easy to the clamping part on it is installed on the lathe.
Summary of the invention
The purpose of this utility model provides a kind of titanizing spiral shell point machine tap that grinds, and it can be installed to this screw tap on the lathe easily.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of titanizing spiral shell point machine tap that grinds, comprise body, and described body is formed by clamping part and tapping section, described clamping part is arranged on the end of described body, and the external diameter of described clamping part is slightly less than the external diameter of described body.
On the basis of such scheme and as the preferred version of such scheme: the outer surface in described tapping section is coated with titanium alloy layer.
The utility model compared to existing technology outstanding and useful technique effect is: the titanizing spiral shell point machine tap that grinds of the present utility model has adopted the clamping part external diameter to be slightly less than the structure of this body diameter, and this grinds titanizing spiral shell point machine tap and can be installed on the lathe easily.
Description of drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is the enlarged drawing of top view of the present utility model.
Fig. 3 is the enlarged drawing at A place among Fig. 1.
The specific embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing;
Referring to Fig. 1, Fig. 2, a kind of titanizing spiral shell point machine tap that grinds of the present utility model comprises body 1, and described body 1 is formed by clamping part 11 and tapping section 12, described clamping part 11 is arranged on the end of described body 1, and the external diameter of described clamping part is slightly less than the external diameter of described body.The titanizing spiral shell point machine tap that grinds of the present utility model has adopted the clamping part external diameter to be slightly less than the structure of this body diameter, and this grinds titanizing spiral shell point machine tap and can be installed on the lathe easily.
In order to improve the service life of this screw tap, this screw tap can also be provided with titanium alloy layer at the outer surface of tapping section 12.Adopt the titanium alloy layer structure, so that this grinding machine contacts with work piece with titanium alloy layer with wear-resisting screw tap, moreover the hardness greater than tapping section of this titanium alloy layer, so that this grinding machine is better with the anti-wear performance of wear-resisting screw tap, longer service life.
Above-described embodiment is preferred embodiment of the present utility model only, is not to limit according to this protection domain of the present utility model, so: all equivalences of doing according to structure of the present utility model, shape, principle change, and all should be covered by within the protection domain of the present utility model.
Claims (2)
1. one kind grinds titanizing spiral shell point machine tap, comprises body, and described body is formed by clamping part and tapping section, and described clamping part is arranged on the end of described body, it is characterized in that: the external diameter of described clamping part is slightly less than the external diameter of described body.
2. the titanizing spiral shell point machine tap that grinds according to claim 1 is characterized in that: the outer surface in described tapping section is coated with titanium alloy layer.
