Description
Technical field
The utility model relates to gear-hobbing machine technical field, particularly a kind of Novel chuck of gear-hobbing machine.
Background technology
In existing gear-hobbing machine, object one end to be processed is fixed by the three-jaw grip slipper arranged, the other end of object to be processed is fixed by thimble, the three-jaw grip slipper used is scroll chuck, but the periphery of material is clamped for ease of scroll chuck, the top of each claw periphery bare terminal end is provided with chamfering, and the clamping face of each claw is typically provided to the plane of asperities.
For make scroll chuck stable clamp rack to be processed, just need to reserve in one end of rack a longer technique clamping position, namely a columniform boss is set in one end of rack, simultaneously when clamping, because the contact surface of each claw and cylindrical boss is little, often make cylindrical boss understand the indent because stress concentrates, affect the machining accuracy of gear-hobbing machine to rack.
Summary of the invention
The purpose of this utility model is defect for prior art and deficiency, provides a kind of structure simple, the Novel chuck of gear-hobbing machine reasonable in design, easy to use.
For achieving the above object, the technical solution adopted in the utility model is: the Novel chuck of a kind of gear-hobbing machine described in the utility model, comprise disk body, three outer pawl pin bodies, parcel, three interior pawls, screw rod, handle, bearing and chassis, described outer pawl pin body one end is provided with outer pawl, all curved shape of outboard sidewalls of described outer pawl and interior pawl; The lateral wall of described interior pawl is fixedly connected by bearing and screw rod one end, and it is external that the screw rod other end stretches out outer pawl pin after being threaded mutually with the screw of outer pawl pin body; Described parcel is arranged in the dish inner chamber of disk body, and the bottom of disk body is fixedly connected by screw and chassis; The center on chassis is provided with convex axle, and the convex axle other end is fixedly connected by bearing and parcel; Disk body lateral wall is disposed radially three cone pinions matched mutually with parcel; Lower surface and the cone pinion phase toe joint of parcel, the upper surface tooth bar of parcel and the lower surface tooth bar phase toe joint of outer pawl pin body.
Further, the described screw rod other end is fixedly connected with handle.
Further, the sidewall area of described outer pawl is greater than the sidewall area of interior pawl.
After adopting said structure, the utility model beneficial effect is: the Novel chuck of a kind of gear-hobbing machine described in the utility model, comprise disk body, three outer pawl pin bodies, parcel, three interior pawls, screw rod, handle, bearing and chassis, described outer pawl pin body one end is provided with outer pawl, all curved shape of outboard sidewalls of described outer pawl and interior pawl; The lateral wall of described interior pawl is fixedly connected by bearing and screw rod one end, and it is external that the screw rod other end stretches out outer pawl pin after being threaded mutually with the screw of outer pawl pin body; Described parcel is arranged in the dish inner chamber of disk body, and the bottom of disk body is fixedly connected by screw and chassis; The center on chassis is provided with convex axle, and the convex axle other end is fixedly connected by bearing and parcel; Disk body lateral wall is disposed radially three cone pinions matched mutually with parcel; Lower surface and the cone pinion phase toe joint of parcel, the upper surface tooth bar of parcel and the lower surface tooth bar phase toe joint of outer pawl pin body.When using the utility model, coordinating to come holding workpiece by inside and outside pawl, the stress of cylindrical boss both can be avoided to concentrate, and then ensure that gear-hobbing machine is to the machining accuracy of rack, the technique clamping length of 1/3rd racks can be reduced again, and then save materials, reduce production cost.It is simple that the utility model has structure, arranges rationally, the advantages such as cost of manufacture is low.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1-2, the Novel chuck of a kind of gear-hobbing machine described in the utility model, comprise the outer pawl pin body 2 of disk body 1, three, parcel 3, three interior pawls 4, screw rod 5, handle 6, bearing 8 and chassis 9, described outer pawl pin body 2 one end is provided with outer pawl 2-1, all curved shape of outboard sidewalls of described outer pawl 2-1 and interior pawl 4; The lateral wall of described interior pawl 4 is fixedly connected by bearing 8 and screw rod 5 one end, and screw rod 5 other end stretches out outside outer pawl pin body 2 after being threaded mutually with the screw of outer pawl pin body 2.
Described parcel 3 is arranged in the dish inner chamber 1-1 of disk body 1, and the bottom of disk body 1 is fixedly connected by screw and chassis 9; The center on chassis 9 is provided with convex axle 7, and convex axle 7 other end is fixedly connected by bearing 8 and parcel 3; Disk body 1 lateral wall is disposed radially three cone pinions 10 matched mutually with parcel 3; Lower surface and the cone pinion 10 phase toe joint of parcel 3, the upper surface tooth bar of parcel 3 and the lower surface tooth bar phase toe joint of outer pawl pin body 2.
When clamping workpiece, workpiece one end will make a call to a fabrication hole in advance, and in first adopting, pawl 4 withstands the inwall of fabrication hole outward, and then clamp process section with outer pawl 2-1, adopt inside and outside clamping, greatly ensure that the stability of clamping, reduce the length of process section simultaneously.
Further, described screw rod 5 other end is fixedly connected with handle, facilitates user to move interior pawl 4 inward or outward, realizes fast clamp.
Further, the sidewall area of described outer pawl 2-1 is greater than the sidewall area of interior pawl 4, is conducive to the stress of balanced workpiece like this, avoids the nip stress of workpiece to concentrate.
When using the utility model, coordinating to come holding workpiece by inside and outside pawl, the stress of cylindrical boss both can be avoided to concentrate, and then ensure that gear-hobbing machine is to the machining accuracy of rack, the technique clamping length of 1/3rd racks can be reduced again, and then save materials, reduce production cost.In addition, this structure is simple, reasonable in design, low cost of manufacture.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
