Description

Tapping sleeve tooth

Technical Field

The utility model relates to a tool to lock handle preparation facilities of people's air defense guard gate, concretely relates to tapping cover tooth.

Background

The tool to lock handle of people's air defense guard gate is mainly by changeing the handle outward, interior commentaries on classics handle and being used for connecting interior commentaries on classics handle and the connecting axle of changeing the handle outward, the upper end of changeing the handle outward and interior commentaries on classics handle all is equipped with a joint that is used for cup jointing the connecting axle, cup joint fixedly through the flat side between the joint of interior commentaries on classics handle and the connecting axle, through threaded connection (the one end of connecting axle is flat side promptly) between the joint of outer commentaries on classics handle and the connecting axle (the other end.

At present, when the connecting shaft is manufactured, a steel bar needs to be clamped on a clamp on one side of a tapping machine, a tapping main machine capable of axially sliding and positioning along the steel bar is arranged on the other side of the tapping machine, a sleeve coaxial with the steel bar is arranged on the tapping main machine, and a tapping sleeve tooth is arranged on one side of the sleeve. The tapping sleeve teeth comprise a sleeve in which tapping teeth are arranged, and two fixing rods which are respectively arranged on two sides of the sleeve and are positioned on the diameter extension line of the sleeve are arranged outside the sleeve. During the use, it is coaxial rather than hugging closely telescopic end with tapping cover tooth earlier to two dead levers with tapping cover tooth support respectively on the cassette of the inner end of tapping machine and outer end, make tapping cover tooth fixed, slide the tapping host computer to the department of being close to the rod iron end again, make the sleeve of tapping host computer and the rod iron coaxial, then start anchor clamps, make anchor clamps at the uniform velocity rotatory, and constantly move to the direction of tapping host computer, and then drive the rod iron rotatory and constantly move, make the rod iron embolia in tapping cover tooth, tap through tapping tooth.

Above-mentioned tapping cover tooth is fixed comparatively troublesome, whether judge that whether the tapping cover tooth leans on naked eye and workman experience to judge completely when coaxial with the sleeve on the tapping host computer, influence the tapping precision of later stage rod iron easily, simultaneously, its fixed also not firm enough, only two fixed points.

Disclosure of Invention

To the not enough of above-mentioned prior art, the utility model aims to solve the technical problem that: how to provide a convenient assembling, and the assembly back is comparatively firm, can ensure with the tapping cover tooth of the sleeve coaxial core of tapping host computer.

In order to solve the technical problem, the utility model discloses a following technical scheme:

the tapping cap tooth is characterized in that a sleeve shaft coaxial with the tapping cap tooth is arranged at one end of the cap tooth body, and an outer convex part used for being in tight fit with a clamping groove at the front end of a tapping machine is arranged on one side of the cap tooth body. Like this, when using, only need embolia the sleeve on the tapping host computer with the one end of cover spiale in, then, the tapping host computer of slip makes the tapping host computer adjacent with the rod iron end of treating processing, and rotatory cover tooth main part makes the evagination card in the draw-in groove of cassette, offsets with the draw-in groove, will overlap the tooth main part and fix on the tapping host computer. After adopting above-mentioned cover tooth main part, its mounting means is simpler, and simultaneously, the area of contact is bigger after cup jointing between the axle that cup joints that add and the sleeve, together with the evagination, forms dual fixed knot structure, and this kind of one side supports the tight fit, and the opposite side cup joints the mode of fixing more firm. In addition, after the sleeve joint shaft sleeve is adopted to connect the tapping sleeve teeth, the sleeve teeth main body and the sleeve joint shaft are coaxial, so that the coaxial centers of the sleeve teeth main body and the sleeve can be ensured, and the processing precision of the tapped steel bar can be ensured.

Furthermore, the cross section of the sleeve joint shaft is circular, and the outer end of the sleeve joint shaft is frustum-shaped. Like this, will cup joint the axle and establish to circularly, the rotatory cover tooth main part in later stage of can being convenient for to the outer convex part that makes in the cover tooth main part can continue rotatory cover tooth main part through the draw-in groove of cassette and after cover tooth main part moves suitable position, makes outer convex part and draw-in groove offset, will cup joint the axle and fix.

Furthermore, the convex part is the slant setting, including a screw sleeve and a screw rod that passes through threaded connection with the screw sleeve of welding on the cover tooth. Like this, in the use, the evagination length of convex part is adjusted to the mode of accessible rotatory screw rod, and then better offsets with the draw-in groove.

Furthermore, at least two waste accommodating holes communicated with the through hole are formed in the outer side of the through hole of the threading main body. Like this, can enter into the waste material holding downthehole when tapping the produced waste material of tooth in the tapping process, can not lead to the fact the influence to the tapping progress, simultaneously, finishes at the tapping, takes off behind the tapping cover tooth, also can tremble the unified position with the waste material together, collects the waste material.

Furthermore, six waste material containing holes are formed, and the six waste material containing holes are circumferentially and uniformly distributed on the outer side of the through hole. Thus, the waste holding holes are uniformly arranged, and the waste is not easy to accumulate.

Furthermore, a lubricating oil channel communicated with the through hole is radially arranged on the threading main body. In this way, lubrication oil can be added to the threading body and the steel bar being machined through the lubrication oil passage during tapping.

Furthermore, the lubricating oil channel is circular, and the diameter of the upper end is larger than that of the lower end. Therefore, in the process of adding lubricating oil, the lubricating oil adding port is large, the waste of the lubricating oil is avoided, and meanwhile, the lubricating oil is more conveniently added.

Compared with the prior art, the utility model discloses the tapping cover tooth that obtains has following advantage:

1. tapping cover tooth comprises cover tooth main part and cover spiale, cup joints through the sleeve on cover spiale and the tapping host computer to and the outer convex part in the cover tooth main part supports the close-fitting to be fixed with the tapping machine goes up the cassette, and this kind of fixed mode is more convenient, and is also more firm simultaneously, can also ensure to overlap tooth main part and sleeve with the axle center.

2. The outer convex part can finely tune in the use, is more convenient to support tightly with the cassette, and the operation is more convenient.
