Abstract
The utility model relates to an all-ground machine screw tap which solves the technical problem that the service life of the screw tap in the prior art is short. The all-ground machine screw tap comprises a clamping part and a tapping part, wherein a thread part and a chip discharge groove are formed on the tapping part, and a cone part is arranged on the clamping part. The crack of the clamping part of the screw tap with the adoption of the structure can be avoided effectively, and the service life of the all-ground machine screw tap is longer.
Description
Technical field
The utility model belongs to the conventional tool technical field of processing column shape internal thread, refers in particular to a kind of fully grinding machine tap.
Background technology
Screw tap is extensively used as the conventional tool of machining internal thread.The fully grinding machine tap of small dimension (M6 is following) mainly is comprised of clamping part and tapping section in the market, is provided with along the axially extended counterbore of screw tap at clamping part, and this counterbore is used for the processing location.Yet the closing of the structure of this small dimension grinds screw tap owing to be provided with counter bore structure, thereby forms partially circularly, namely generated thinner thin-walled.During use, this screw tap is fixed on the fully grinding machine by clamping part, and the clamping part of this screw tap is stressed larger, causes clamping part to burst apart.The existence of counterbore has had a strong impact on service life of this fully grinding machine tap.
Summary of the invention
The purpose of this utility model provides a kind of fully grinding machine tap of long service life.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of fully grinding machine tap, comprise clamping part and tapping section, and have spiro tooth part and chip area in the described tapping section, be provided with conus portion at described clamping part.
On the basis of such scheme and as the preferred version of such scheme: described conus portion and described clamping part are one.
On the basis of such scheme and as the preferred version of such scheme: described chip area extends axially and runs through described spiro tooth part along screw tap.
On the basis of such scheme and as the preferred version of such scheme: described chip area is 3 and circumferentially uniform along described tapping section.
On the basis of such scheme and as the preferred version of such scheme: described tapping section has conus portion.
The effect that the utility model compared with prior art has is: fully grinding machine tap of the present utility model is provided with conus portion at clamping part, it has positioning action, replaced the prior art plug tap to locate with counterbore, because conus portion is solid, its ability that can bear pressure is strong, in two kinds of stressed identical situations of screw tap, effectively avoid the clamping part of this screw tap to burst apart, the longer service life of fully grinding machine tap of the present utility model.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is front view of the present utility model.
The specific embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing;
As shown in Figure 1 and Figure 2, fully grinding machine tap of the present utility model comprises clamping part 1 and tapping section 2, has spiro tooth part 21 and chip area 22 in the tapping section 2, is provided with conus portion 3 at clamping part.Fully grinding machine tap of the present utility model is provided with conus portion at clamping part, it has positioning action, replaced the prior art plug tap to locate with counterbore, because conus portion is solid, its ability that can bear pressure is strong, in two kinds of stressed identical situations of screw tap, the longer service life of fully grinding machine tap of the present utility model.
In the present embodiment, conus portion 3 is one with clamping part 1.Certainly, conus portion can be split with clamping part also, conus portion and clamping part welding.
During tapping, the spiro tooth part in the tapping section pushes mutually with workpiece and spiro tooth part is cut workpiece, thereby processes screw thread at workpiece.Add and produce inevitably metal fillings man-hour, successfully discharge in chip area in order to make metal fillings, chip area 22 is preferred to adopt following structure, and chip area 22 extends axially and runs through spiro tooth part 21 along screw tap.Adopt the chip area of this structure, it compared with the existing, the debris discharging chute structure that the utility model provides, its length is longer, correspondingly, the cavity that forms between itself and the workpiece is also larger, and the metal fillings that can hold is more, avoid causing some metal fillings to enter between workpiece and the thread because metal fillings is full of whole chip area, make the tooth that processes more neat, smooth.
Preferably, chip area 22 is 3 and circumferentially uniform along tapping section 2.Certainly, chip area also can be selected other quantity.Has conus portion 4 in the tapping section.Adopt the tapping section of this structure, it is conducive to tapping section and enters workpiece.
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 (5)
1. a fully grinding machine tap comprises clamping part and tapping section, has spiro tooth part and chip area in the described tapping section, it is characterized in that: be provided with conus portion at described clamping part.
