Abstract
The utility model relates to a threading turning tool with an adjustable lead angle, which comprises a tool body and an adjusting sleeve. The threading turning tool with the adjustable lead angle is characterized in that a conical tool handle is arranged on the tool body; the tail part of the conical tool handle is provided with an annular groove; the conical tool handle is matched with a conical inner hole of the square adjusting sleeve; the tail part of the adjusting sleeve is provided with a nut; and an opening gasket is also arranged between the nut and the annular groove of the conical tool handle. And the conical tool handle is of a Morse taper of 4-6. Compared with the prior art, the threading turning tool with the adjustable lead angle has the benefits that: the conical tool handle can rotate by any angle along the axis of the conical tool handle; as long as the handle of the turning tool is rotated, a tool bit of the turning tool can obtain different front angles and back angles to process threads of different lead angles; moreover, the handle of the turning tool and the adjusting sleeve are fixed by thread and opening gasket structures, which leads the turning tool to be mounted and dismounted more conveniently, and can effectively improve the processing efficiency.
Description
Technical field
The utility model relates to the lathe tools field, relates in particular to the adjustable threading tool of a kind of lead angle.
Background technology
At present on engine lathe, when the threads of lead screw of different lead angles is processed in turning,, change the working orthogonal clearance of threading tool along with the change of leading screw lead angle, generally be to will adding a lead angle in the face of the relief angle on the workpiece left side, the right to deduct a lead angle; The lathe tool anterior angle is not generally as long as the bit alignment rotation can change, for obtaining suitable anterior angle and relief angle, need carry out sharpening to the rake face and the back knife face of lathe tool, because lathe tool is commonly square cutter hub, after it was clipped on the knife rest, anterior angle and relief angle were fixed, for adapting to various lead angle screw thread, can only frequently whet a knife or tool changing, production efficiency is low.
In the prior art, the patent No. is CN200920043747.X, chuck and external jacket in threading tool anchor clamps, these anchor clamps comprise, and interior chuck places among the external jacket, and the inboard of interior chuck is a square groove, and the outside is an arc surface, and the inboard of external jacket is an arc surface.This threading tool anchor clamps can be used for the special type anchor clamps of turning trapezoidal thread expeditiously, can reduce the sharpening amount, thereby enhance productivity, fine setting by angle, can guarantee carrying out smoothly of turning, fabricated structure is different with the utility model structure up and down for they, when cutting force is big, and play before and after lathe tool easily takes place.
Summary of the invention
The purpose of this utility model provides the adjustable threading tool of a kind of lead angle, is suitable for the thread turning of multiple lead angle, flexible operation, accurate positioning.
For achieving the above object, the utility model is achieved through the following technical solutions:
The adjustable threading tool of a kind of lead angle, comprise cutter hub, adjust cover, it is characterized in that, cutter hub is provided with the taper handle of a knife, the tapered knife handle tail is provided with annular groove, described taper handle of a knife matches with the cone-shaped inner hole of square adjustment cover, adjusts the cover afterbody and is provided with nut, also is provided with open washer between the annular groove of nut and tapered knife handle tail.
Described taper handle of a knife is four to No. six taperings of Mohs.
Compared with prior art, the beneficial effects of the utility model are: the taper handle of a knife can rotate arbitrarily angled around himself axis, as long as the handle of a knife of rotation lathe tool, the lathe tool cutter head can obtain different anterior angles and relief angle, process the screw thread of different lead angles, the handle of a knife of lathe tool and fixedly employing screw thread and the open washer structure of adjusting cover make the installation of lathe tool, dismounting more convenient, can improve working (machining) efficiency effectively.
Description of drawings
Fig. 1 is the utility model example structure schematic diagram;
Fig. 2 is the side view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:
See Fig. 1, Fig. 2, it is the adjustable threading tool example structure of a kind of lead angle of the utility model schematic diagram, comprise cutter hub 1, adjust cover 2, cutter hub 1 is provided with taper handle of a knife 3, tapered knife handle tail 6 is provided with annular groove 7, described taper handle of a knife 3 matches with the cone-shaped inner hole of square adjustment cover 2, adjusts cover 2 afterbodys and is provided with nut 4, also is provided with open washer 5 between the annular groove 7 of nut 4 and tapered knife handle tail 6.
Described taper handle of a knife 3 is advisable for four to No. six taperings of Mohs, especially with No. six tapering the bests of Mohs.
The utility model can be fixed on the knife rest of lathe easily, realizes the processing of screw thread, and its method of adjustment is:
1) according to the thread helix lift angle that will process, rotate the handle of a knife 3 of lathe tool by hand, adjust its angle in adjusting cover 2, to obtain suitable anterior angle and the relief angle of lathe tool;
2) insert open washer 5, screw nut 4, fix the position of cutter hub 1 in square adjustment cover 2;
3) the threading tool integral installation that assembles more than the general gets final product machining screw on lathe saddle.
Claims (2)
1. adjustable threading tool of lead angle, comprise cutter hub, adjust cover, it is characterized in that, cutter hub is provided with the taper handle of a knife, the tapered knife handle tail is provided with annular groove, described taper handle of a knife matches with the cone-shaped inner hole of square adjustment cover, adjusts the cover afterbody and is provided with nut, also is provided with open washer between the annular groove of nut and tapered knife handle tail.
2. the adjustable threading tool of a kind of lead angle according to claim 1 is characterized in that, described taper handle of a knife is four to No. six taperings of Mohs.
