Abstract
The utility model discloses a screw thread cutting tool, which comprises a handle, a screw die and a screw die seat, wherein, the screw die seat is provided with a threaded hole for mounting a guide sleeve; the center of the guide sleeve is provided with a guide hole of which the diameter is equal to the nominal diameters of processed threads. The utility model has the advantages of simple cutter structure, simple manufacture, reduced labour intensity and improved work efficiency.
Description
The utility model relates to the cutter of metal processing usefulness, and more particularly, the utility model relates to the screw thread cutting tool.
Manual cutting external screw thread cutter (being commonly called as the hitch spanner) is the instrument of a kind of machining screw of using always.It is one of the most frequently used instrument of mechanic.Traditional hitch method is that screw die is installed in the installing hole of hitch spanner, fixes and transmit moment of torsion with limit screw.The oblique angle of the guiding conical surface alignment pieces round bar of screw die, guarantee that with technical ability the screw die end face is vertical with axis of workpiece by rule of thumb during hitch by the workman.This cutter not only efficient is low, and often causing simultaneously quality problems, screw die end face and axis of workpiece out of plumb is to cause the not just reason of (the dark one side of tooth one side is shallow) and mashed tooth of workpiece thread form.
The purpose of this utility model is the shortcoming that overcomes prior art, and tool axis easily departs from the difficult problem that axis of workpiece causes processed threaded line to tilt when solving hitch, and a kind of device that makes the cutter positioning guiding is provided.
The purpose of this utility model is achieved by following technical proposals.
Screw thread cutting tool of the present utility model comprises handle, screw die, threading die seat, and described threading die seat is provided with a threaded hole, and in order to fairlead to be installed, described fairlead center is provided with a pilot hole, and its diameter equals the nominal diameter of processed screw thread.
The utility model will be further described below in conjunction with accompanying drawing.
Accompanying drawing is the structural representation of positive thread cutter of the present utility model.
In the drawings, handle 1 is designed to one with threading die seat 6, and the installing hole of the upper surface of threading die seat 6 is installed screw die 5, the lower surface of described threading die seat 6 is provided with a threaded hole 4, in order to fairlead 2 to be installed, that is to say that described fairlead 2 is connected with the hole 4 of threading die seat 6 by connecting thread.The diameter phi D of the pilot hole 3 on the fairlead 2 is a principal parameter, and it is corresponding with screw die, supporting use, and promptly the diameter of pilot hole 3 equals the diameter of screw die machining screw.The fairlead of different size is connected with hole 4 as general-purpose interface by standardized connecting thread.The diameter M in the connecting thread hole 4 on the hitch spanner is coaxial with the screw die installing hole, and the pilot hole 3 on the fairlead 2 is coaxial with the external screw thread cylinder, and is coaxial with the screw die center to guarantee pilot hole 3.When carrying out hitch when operation, the pilot hole 3 of fairlead 2 is inserted in workpiece, fairlead, pilot hole and the screw die guiding conical surface common guarantee tram between cutter and the workpiece.
The utility model compared with prior art has the following advantages:
1. at hitch bolt die seat fairlead is set, can significantly improves the quality of hitch threading, raise labour productivity, Reduce the difficulty of operation.
2. fairlead is dismantled and assembled, and the fairlead of different size can be used for having reduced manufacturing cost on the same threading die seat.
3. simple in structure, be convenient to realize.
Claims (1)
1. a screw thread cutting tool comprises handle, screw die, threading die seat, it is characterized in that, described threading die seat is provided with a threaded hole, in order to fairlead to be installed, described fairlead center is provided with a pilot hole, and its diameter equals the nominal diameter of processed screw thread.
