Abstract
The invention relates to a novel screw tap clamp for stainless steel material tapping. The novel screw tap clamp comprises a clamp casing and a screw tap. A C-shaped groove is arranged in the clamp casing, a limiting main body is installed on the inner side of the C-shaped groove through a locating pin, a loosening clamping pressing sleeve is installed in the limiting main body and presses the screw tap through a steel ball, and an elastic seal ring is further arranged between the clamp casing and the limiting main body. According to the technical scheme, a cutter material is saved, cutter manufacturing cost is reduced, the screw tap is located accurately, transmitted torque is large, the screw tap is installed and dismantled rapidly, auxiliary time is saved, and production efficiency is improved.
Description
Technical field
The present invention relates to mechanical manufacturing field, be specifically related to a kind of fixture of the Two-end Tap Applied for the stainless steel material tapping.
Background technology
Stainless steel is as a kind of good resistant material, and possesses the excellent serviceability of the aspects such as intensity and toughness are arranged, and makes it to be widely used in every field such as machine parts and pharmacy, chemical industry equipments.But, along with the continuous increase of stainless steel consumption, stainless steel just becomes increasingly conspicuous as the processing problems of hard-cutting material.Exactly because stainless steel has good plasticity and certain toughness and intensity, so cause the work hardening phenomenon serious, easily the cutter cutting edge is caused to damage.Because under its high temperature, intensity is high, pyroconductivity is low, so cutting temperature is high, and the Cutter wear impact is very large, and just, because it has sizable toughness and intensity, percentage elongation is large, therefore very easily form built-up edge.These situations are processed for stainless steel, and especially tapping will bring very large difficulty.
Traditional screw tap material is common high-speed steel.Have data to show, processing stainless steel can carry out the TiN coating at surface of high speed steel, to reduce the cutting moment of torque, extends life of tap, improves thread quality.Experimental results show that, the TiN coating can make the frictional force between screw tap surface and stainless steel material descend, make the cutting moment of torque descend 1/3～1/2, the TiN coating can also effectively suppress screw tap and stainless affinity interaction, obviously stop the bonding between stainless steel and screw tap, thereby the thread surface quality is improved, and our screw tap commonly used only has an end that screw thread is arranged at present, and the other end is handle of a knife.This structure makes the knife bar afterbody must the side's of being designed to body or the conical surface, with can transmitting torque.And the live part of the screw thread of screw tap only accounts for 40% left and right of tap length, the screw tap material is most of for shank portion, relatively wastes material.
Summary of the invention
Because the two-end tap is a kind of new structure, general fixture can't clamping, the object of the invention is to overcome the problem that prior art exists, and a kind of fixture of the Two-end Tap Applied for the stainless steel material tapping is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of fixture of the Two-end Tap Applied for the stainless steel material tapping, comprise fixture housing and screw tap, be provided with C shape groove in described fixture housing, by alignment pin, spacing main body is installed in described C shape groove inboard, loose cramping cover is installed in described spacing main body, described loose cramping cover compresses described screw tap by steel ball, between described fixture housing and described spacing main body, also is provided with elastic seal ring.
Further, described spacing main body and described loose cramping cover are fixed by alignment pin.
Preferably, described screw tap is that the two-end tap is without shank, and cobalt Co ion is injected on described screw tap surface, between the interior axial end of described loose cramping cover and described spacing main body, spring also is installed, and between the interior axial end of described spacing main body and described fixture housing, described spring also is installed.
The invention has the beneficial effects as follows:
Adopt technical solution of the present invention, saved cutter material, reduced the cutter manufacturing cost, the screw tap accurate positioning, transmitting torque is larger, and mounting or dismounting fast, are saved non-cutting time, enhance productivity.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Number in the figure explanation: 1, fixture housing, 2, screw tap, 3, alignment pin, 4, spacing main body, 5, loose cramping cover, 6, steel ball, 7, elastic seal ring, 8, alignment pin, 9, spring.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Shown in Fig. 1, a kind of fixture of the Two-end Tap Applied for the stainless steel material tapping, comprise fixture housing 1 and screw tap 2, be provided with C shape groove in described fixture housing 1, by alignment pin 3, spacing main body 4 is installed in described C shape groove inboard, loose cramping cover 5 is installed in described spacing main body 4, and described loose cramping cover 5 compresses described screw tap 2 by steel ball 6, between described fixture housing 1 and described spacing main body 4, also is provided with elastic seal ring 7.
Further, described spacing main body 4 is fixing by alignment pin 8 with described loose cramping cover 5.
Preferably, described screw tap 2 is that the two-end tap is without shank, and cobalt Co ion is injected on described screw tap 2 surfaces, between the interior axial end of described loose cramping cover 5 and described spacing main body 4, spring 9 also is installed, and between the interior axial end of described spacing main body 4 and described fixture housing 1, described spring 9 also is installed.
Principle of the present invention:
Promoting loose cramping cover 5 can easily and turn around screw tap 2 dismounting.Because the spacing main body 4 of the effect of elastic seal ring 7 can be slightly unsteady in fixture housing 1, so that alignment pieces hole, and there in the axial effect due to spring 9, also have a little to permit to be moving, so that during screw tap 2 advance and retreat, permission some deviation slightly on pitch, adopt surface to inject the high speed steel screw tap of cobalt Co ion, can improve 1.5～2.0 times of screw tap 2 durabilitys, and the wearing and tearing of cutter tooth are more even.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
