Abstract

Disclosed in the invention is a guiding screw tap comprising a screw tap body and a guiding post. Screw teeth are arranged at the cylindrical surface of one end of the screw tap body and a square clamping head is arranged at the other end. A chip pocket is formed in the surfaces of the screw teeth at the axial direction. A threaded hole is formed in the front ends of the screw teeth. A threaded mounting head is arranged at one end of the guiding post; and the guiding post is connected with the screw tap body based on cooperation of the mounting head and the threaded hole. According to the invention, the structure is simple and the guiding screw tap can be used conveniently. And defects that exist when the existing screw tap is used for carrying out tapping can be effectively overcome.

Description

A kind of guide tap
Technical field
The present invention relates to a kind of small tool, be specifically related to a kind of guide tap.
Background technology
Pincers worker is the very important work post of machine industry, and along with the fast development of equipment manufacture and the extensive use of high-end Precision Manufacturing Technology, the status of pincers worker in manufacturing industry is also more and more higher.Tapping is one of basic skills of pincers worker.When using existing screw tap tapping, because screw tap is in oral area easily left and right or the swing of bottom outlet, be difficult to reach screw tap and the orthogonal requirement of bottom outlet end face, this situation is corrected timely and effectively as can not get, and will cause that screw tap is fractureed, screw thread form and size do not reach requirement.In addition, because screw tap and bottom outlet end face easily tilt, operating personnel need repeatedly to adjust, and this easily destroys the shape of bottom outlet oral area, cause between screw tap and bottom outlet and are difficult to location, certainly will affect the efficiency of tapping.
Summary of the invention
The object of the present invention is to provide the guide tap that a kind of structure is simple, easy to use, it can solve in background technology various drawbacks existing when using existing tap tapping.
For achieving the above object, technical scheme of the present invention, it comprises wire cone and lead, and the face of cylinder of described wire cone one end is provided with a tooth, the other end is provided with square clamping head; The surface of described silk tooth is axially arranged with chip pocket, and the front end of described silk tooth is provided with screwed hole; One end of described lead is provided with screw thread mounting head, and lead is connected with wire cone with the cooperation of screwed hole by mounting head.
In technique scheme, the angle between described chip pocket and the axis of wire cone is 5 ° ~ 10 °.
Adopt after technique scheme, utilize the guiding between lead and bottom outlet, can effectively prevent and use existing screw tap to produce crooked between stage screw tap and bottom outlet end face rising to attack, thus reduce screw tap and fractureed, guarantee Tapping Quality, and improve tapping efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of guide tap of the present invention;
In accompanying drawing, each label is: 1, wire cone, 11, clamping head, 12, silk tooth, 13, chip pocket, 14, screwed hole, 2, lead.
Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of guide tap of the present invention is described further:
As seen from Figure 1, the present invention it comprise wire cone 1 and lead 2, the face of cylinder of described wire cone 1 one end is provided with a tooth 12, the other end is provided with square clamping head 11; The front end of described silk tooth 12 is provided with screwed hole 14; One end of described lead 2 is provided with screw thread mounting head 21, and lead 2 is connected with wire cone 1 with the cooperation of screwed hole 14 by mounting head 21.
Using method of the present invention is, first the mounting head 21 of lead 2 be tightened in the screwed hole 14 of wire cone 1 front end, then be arranged on by the clamping head 11 of screw tap on strand thick stick, the right hand holds the center of strand thick stick, make lead 2 insert in bottom outlet, left hand firmly rotates strand thick stick normally can carry out tapping.
In the present embodiment, for ease of discharging the iron filings that tapping produces, the surface of described silk tooth 12 is axially arranged with chip pocket 13, and the angle between described chip pocket 13 and the axis of wire cone 1 is 5 ° ~ 10 °.
In the present embodiment, for ease of the good guidance between lead 2 and thread Pilot hole, the diameter 0.05 ~ 0.10mm less of the path of screw thread of described lead.
