Description
Technical field
The utility model belongs to machine tools field, especially relates to a kind of Two-end Tap Applied.
Background technology
Screw tap is a kind of cutter of machining internal thread, spiral tap and straight sword screw tap can be divided into according to shape, set tap and machine tap can be divided into according to environment for use, screw tap is the main instrument of operator's machining screw, but there is following shortcoming in screw tap conventional in prior art: one when machining screw, during machining screw, normally first process a circular hole with drill bit, utilize screw tap machining internal thread in circular hole afterwards, so just need to complete respectively in two procedures with two kinds of cutters, not only time-consuming but also require great effort, and certain damage may be caused to circular hole while replacing instrument, accuracy is reduced, two, when the internal thread of processing work, screw tap conehead adds workman and is easily fractureed man-hour, and after conehead fractures, whole screw tap just can not re-use, and adds production cost, and meanwhile, the screw tap of fracture is also usually residual cannot be taken out within the workpiece, adds percent defective.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of operating efficiency and the accuracy that improve machining internal thread, reduces production cost, increases the service life, and conehead of avoiding fractureing remains, Two-end Tap Applied easy to loading and unloading.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of Two-end Tap Applied, comprises conehead and taper shank, also comprises drill bit, and described drill bit, conehead and taper shank are split-type structural; Offering one in described conehead along conehead axial line runs through the through hole of conehead, is provided with internal thread in described through hole; Described drill bit one end is provided with the cylindrical protrusions I along drill bit axial line, and described protruding I is outside equipped with screw thread; Described taper shank one end is provided with the cylindrical protrusions II along taper shank axial line, and described protruding II is outside equipped with screw thread; Described conehead one end is threaded by the through hole formation that to match with the projection I on drill bit, and the other end is threaded by the through hole formation that to match with the projection II on taper shank.
Described drill bit and protruding I is formed in one structure.
Described taper shank and protruding II is formed in one structure.
Described taper shank offers two clamping planes be parallel to each other.
Owing to adopting technique scheme, the projection I of the through hole in described conehead and drill bit one end is formed by screw thread and removably connects, machining internal thread can be carried out by direct screw tap after drill bit beats via hole, the operation of dispersion is rationally concentrated, shortens operation number, simplify flow process, eliminate tool change time, improve production efficiency, and bore the structure of attacking one and also assures that its precision of processing, thus ensure that product quality;
The projection II of the through hole in described conehead and taper shank one end is formed by screw thread and removably connects, once there is the situation of screw tap fracture, can be taken out by residual screw tap within the workpiece like a cork with screwdriver, and conehead of avoiding fractureing remains;
Described drill bit, conehead and taper shank are split-type structural, and structure is simple, easy to loading and unloading, even if when screw tap conehead interrupts, the taper shank of this screw tap and drill bit can also continue to use, and can not cause waste, reduce production cost, increase the service life.
The beneficial effects of the utility model are: have and improve the operating efficiency of machining internal thread and accuracy, reduce production cost, increase the service life, and conehead of avoiding fractureing remains, advantage easy to loading and unloading.
Accompanying drawing explanation
Below by with reference to accompanying drawing describe the utility model particularly in conjunction with example, advantage of the present utility model and implementation will be more obvious, wherein content shown in accompanying drawing is only for explanation explanation of the present utility model, and do not form restriction of going up in all senses of the present utility model, in the accompanying drawings:

Detailed description of the invention
As shown in Figure 1, a kind of Two-end Tap Applied of the utility model, comprise conehead 1 and taper shank 2, also comprise drill bit 3, described drill bit 3, conehead 1 and taper shank 2 is split-type structural; Offering one in described conehead 1 along conehead 1 axial line runs through the through hole 11 of conehead 1, is provided with internal thread in described through hole 11; Described drill bit 3 one end is provided with the cylindrical protrusions I 31 along drill bit 3 axial line, and described protruding I 31 are outside equipped with screw thread; Described taper shank 2 one end is provided with the cylindrical protrusions II 21 along taper shank 2 axial line, and described protruding II 21 are outside equipped with screw thread; Described conehead 1 one end is threaded by through hole 11 formation that to match with the projection I 31 on drill bit 3, and the other end is threaded by through hole 11 formation that to match with the projection II 21 on taper shank 2; Described drill bit 3 and protruding I 31 is formed in one structure; Described taper shank 2 and protruding II 21 is formed in one structure; Described taper shank 2 offers two clamping planes be parallel to each other 22.
The course of work of this example: the projection I 31 of the through hole 11 in conehead 1 and drill bit 3 one end is formed by screw thread and removably connects, directly machining internal thread can be carried out with conehead 1 after drill bit 3 dozens of via holes, the operation of dispersion is rationally concentrated, shorten operation number, simplify flow process, eliminate tool change time, improve production efficiency, and bore the structure of attacking one and also assures that its precision of processing, thus ensure that product quality; The projection II 21 of the through hole 11 in conehead 1 and taper shank 2 one end is formed by screw thread and removably connect, once there is the situation that conehead 1 ruptures, can be taken out by residual conehead 1 within the workpiece like a cork with screwdriver, conehead 1 of avoiding fractureing is residual; Drill bit 3, conehead 1 and taper shank 2 is split-type structural, and structure is simple, easy to loading and unloading, even if when screw tap conehead 1 interrupts, the taper shank 2 of this screw tap and drill bit 3 can also continue to use, and can not cause waste, reduce production cost, increase the service life.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model scope change and improve, and all should still belong within this patent covering scope.
