Description
Technical field
The utility model is related to a kind of lathe auxiliary mould, more particularly to a kind of lathe process internal thread auxiliary mould, special
Shi He not triangle internal thread of the lathe process pitch less than 2 millimeters.
Background technology
It is typically directly at manufactured screw thread bottom when lathe process pitch is less than 2 millimeters of angular thread workpiece
In the hole of footpath, with the direct tapping of machine tap, or first screw thread carried out it is rough turn, then completed again with screw tap screw thread plus
Work.Inner hole thread is processed using above-mentioned brill offense method, although operating method is simple, production efficiency is high, but machining accuracy is relatively low, and
Easily there is the situation of " rotten tooth ", " disorderly button " and the screw tap that fractures.
The content of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of lathe process internal thread auxiliary mould.It is tied
Structure is simple, and concentricity is high, and efficiency, precision are high, and labor intensity is low.
The technical scheme in the invention for solving the technical problem is：The left end of main body overcoat is fluted, groove
Inwall on be threadably secured on adjusting nut, the external cylindrical surface of adjusting nut and be threadably secured locking nut, locking screw
Mother can be by cover locking outside adjusting nut and main body, and having in adjusting nut has conical grooves on wall, setting-in taper connects in conical grooves
Junctor, taper connector stretches out adjusting nut with gap to the left, and the left end of taper connector fixes screw tap, the right side of taper connector
End is by there is the left end of spring, and the right-hand member of spring is leaned against on the groove bottom wall, and spring is between taper connector and adjusting nut
Frictional force is provided, when cutting force is excessive, screw tap will produce idle running, can effectively prevent " rotten tooth ", " disorderly button " and fracture
The situation of screw tap occurs；The right-hand member of the main body overcoat has centre bore, is set with stroke shaft, stroke shaft and car centre bore internal clearance
Tailstock frame is fixed.
The utility model has following advantages：1) it is, simple in construction, it is adaptable to process the angular thread that pitch is less than 2 millimeters
Workpiece；2), because when cutting tapping being guided by workpiece bottom footpath hole, so as to ensure that concentricity；3), with directly using hand
Compared with screw tap tapping, shortening centering centering consumed non-cutting time improves process velocity and Mass accuracy；4), subtract
The light working strength of lathe operation person；5), because its part is assembly, assembly and disassembly is convenient, wherein most assembly
It is reusable, reduce cost of manufacture.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the utility model sectional view.
Embodiment
As shown in figure 1, adjusting nut 4 is threadably secured on the left end of main body overcoat 8 fluted 6, the inwall of groove 6,
Locking nut 3 is threadably secured on the external cylindrical surface of adjusting nut 4, locking nut 3 can be by adjusting nut 4 and main body overcoat
Have on wall in 8 lockings, adjusting nut 4 and have conical grooves 5, setting-in taper connector 2 in conical grooves 5, taper connector 2 to the left between
Adjusting nut 4 is stretched out in unoccupied place, and the left end of taper connector 2 fixes screw tap 1, and the right-hand member of taper connector 2 is by there is a left side for spring 7
End, the right-hand member of spring 7 is leaned against on the bottom wall of groove 6, and spring 7 is to provide friction between taper connector 2 and adjusting nut 4
Power, when cutting force is excessive, screw tap 1 will produce idle running, can effectively prevent the shape of " rotten tooth ", " disorderly button " and the screw tap that fractures
Condition occurs；The right-hand member of the main body overcoat 8 has centre bore, is set with stroke shaft 11, stroke shaft 11 and lathe centre bore internal clearance
The frame of tail 13 is fixed.
There are the axial elongated slot 10 communicated with centre bore, the internal clearance of elongated slot 10 on the wall of main body overcoat 8 of the central hole
Ground is oriented to control screw 9 and is fixed on described stroke shaft 11 equipped with control screw 9 is oriented to.
The right-hand member of the stroke shaft 11 is the circular cone coordinated with tail stock tapered sleeve 12.
