Abstract

The utility model relates to a cutter for processing knuckles at a shaft shoulder and a journal, which includes a turning tool composed of a cutter head and a cutter body, and is characterized by further including a cutter bar composed of a assembling body and a fixing body, also characterized in that a worm assembled with a hand wheel on one end portion is rotationally assembled in the assembling body, a worm gear engaged with the worm is rotationally supported on the assembling body by a shaft, the cutter body of the turning tool is fixed on the root circle circumferential surface of the worm gear by a fixing member, and the cutter head of the turning tool radially stretches along worm gear gear teeth on the cutter body, swinging to and from on the working plane with the worm gear. The cutter for processing knuckles processes workpieces in a turning manner by using worm gear worm transmission having self-locking function to drive the turning tool to swing to and from on the working plane for turning the workpieces, to form smooth knuckles on the workpieces, has advantages of being simple in structure, convenient in use, saving in labor and effort and reliable in moulding, and is suitable for ordinary lathes especially.

Description

A kind of process tool of knuckle

Technical field

The utility model relates to a kind of cutter that is used for lathe, especially a kind of process tool that is used to process the shaft shoulder place knuckle of axle.

Background technology

We know, for the axle that bears complex load, generally are designed to transition fillet externally connectedly at its shaft shoulder place, and this transition fillet externally connected turning angle of generally taking progressively to change lathe tool on lathe is finished.Existing lathe tool is made up of cutter head and cutter hub two parts, and cutter head is used for cutting, and cutter hub is used for installing.Along with the progressively increasing of shipbuilding tonnage, its marine shafting also can the comparatively thick axle system of corresponding employing.Thick axle ties up to the lathe tool that adopts existing structure on the lathe and processes by transfer top rake degree progressively, and knuckle size and roughness that it processes are difficult to reach technological requirement.In order to guarantee fillet size and axle journal smooth transition, also to adopt hand operated grinding wheel that it is carried out form grinding after the car system, there is the deficiency that wastes time and energy.

Summary of the invention

Do not reach technological requirement and also will adopt emery wheel to carry out reconditioning and exist the deficiency that wastes time and energy in order to overcome the thick axle of existing lathe tool processing system, the utility model provide a kind of simple in structure, reasonable in design, cost is low, the process tool of easy to use, the reliable knuckle of turning moulding.

The technical scheme that the utility model technical solution problem is adopted is: a kind of process tool of knuckle, and it comprises a lathe tool of being made up of cutter head and cutter hub, it is characterized in that: it also comprises:

One knife bar, this knife bar can be made up of with the fixed body that jig fixes an assembled body and;

One worm screw, this worm screw is rotated and is assemblied in the assembled body of described knife bar;

One worm gear, this worm gear, and are meshed with described worm screw in assembled body on the assembled body of described knife bar by the axle rotational support;

One handwheel, this handwheel are assemblied in the end of described worm screw, can drive worm screw and rotate;

The cutter hub of described lathe tool is fixed on by fixture on the root circle circumferential surface of described worm gear, and the cutter head of described lathe tool is at the circumferentially extending of the cutter hub upper edge worm gear gear teeth, and with worm gear reciprocally swinging on working face.

The process tool of described knuckle, it also comprises a holding screw, and this is marked closely on the end face of assembled body that screw is assemblied in described knife bar, and its end leans on the radial end face of described worm gear.

The utility model is to have adopted the worm and gear transmission on the assembled body of knife bar, and drives lathe tool on worm gear reciprocally swinging on working face and and form smooth knuckle on workpiece with turner.Adopt the turbine and worm transmission to have the drive mechanism compactness, stable drive, the characteristics that gearratio is big, worm tooth is continuous helical tooth, and has auto-lock function, with the engagement of the worm gear gear teeth be to progress into or withdraw from engagement, overcome the defective that engine lathe does not possess longitudinal and transverse while feed.The utility model and prior art mutually, have simple in structure, reasonable in design, cost is low, easy to use, turning saves labor, the reliable advantage of moulding, be particularly suitable on engine lathe, using.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 1 is a kind of structural front view of the present utility model.

Fig. 2 is the cutaway view along A-A line among Fig. 1.

Among the figure: 1. handwheel, 2. worm screw, 3. lathe tool, 301. cutter hubs, 302. cutter heads, 4. lock-screw, 5. worm gear, 6. spool, 7. holding screw, 8. bearing, 9. bearing (ball) cover, 10. knife bar, 1001. fixed bodies, 1002. assembled body.

The specific embodiment

In Fig. 1, a kind of process tool of knuckle, it comprises lathe tool 3, this lathe tool 3 is made up of cutter head 302 and cutter hub 301.Cutter head 302 is used for cutting, and cutter hub 301 is used for installing.

The process tool of the utility model knuckle, it also comprises a knife bar 10, this knife bar 10 is made up of an assembled body 1001 and a fixed body 1002.Fixed body 1002 can fix with jig.

In Fig. 1, Fig. 2, in assembled body 1001 by two bearings 8 rotate assembling one worm screw 2, one worm gears 5 by one 6 rotational support on assembled body 1001, and assembled body 1001 inner with worm screw 2 between tooth mesh.

In Fig. 1, be equipped with a handwheel 1 in the end of the worm screw 2 that is positioned at assembled body 1001.

In Fig. 1, Fig. 2, in order to prevent the axial float of worm gear 5, on an end face of the assembled body 1001 of knife bar 10, holding screw 7 is housed, the end of this holding screw 7 leans on the radial end face of worm gear 5.

For bearing 8 being played axial location and dustproof, sealing function, the bearing (ball) cover 9 that on the assembled body 1001 of bearing 8 both sides, assembles respectively.

As shown in Figure 1 and Figure 2, the cutter hub 301 of lathe tool 3 is fixed on by lock-screw 4 on the circumferential surface of worm gear 5 root circles, and the cutter head 302 of lathe tool 3 is at the circumferentially extending of the cutter hub 301 upper edge worm gear gear teeth.

Back and forth rotate handwheel 1, drive worm screw 2 and back and forth rotate, the worm gear 5 that is meshed with worm screw 2 reciprocally swinging under the drive of worm screw 2 is fixed on lathe tool 3 on the worm gear 5 with worm gear 5 reciprocally swinging on working face, the shaft shoulder on the axle and axle journal place are carried out turning, and can form smooth knuckle.

The utility model is simple in structure, easy to use, turning saves labor, moulding is reliable, is particularly suitable for using on engine lathe.
