Description

A kind of signal gear ring hobber structure

Technical field

The utility model belongs to Gear Processing field, and in particular to a kind of signal gear ring hobber structure.

Background technique

Signal gear ring is a kind of thin gear ring, and circumferentially the gear teeth are imperfect, lacks several teeth, and there are also the teeth of several teeth Slot needs Baking soda to deepen, finally to meet the needs of client is to signal gear ring product.

Existing signal gear ring processing flow: rolling out signal teeth on gear-hobbing machine, and part signal tooth is milled away on milling machine Formed hypodontia, and milling machine get on Baking soda deepen.

Technology mode needs are respectively completed gear hobbing, mill teeth, complex process on two lathes, and equipment cost also increases therewith Add.

Utility model content

In view of this, gear hobbing, mill teeth are concentrated the purpose of this utility model is to provide a kind of signal gear ring hobber structure As soon as completing gear hobbing, the mill teeth operation of signal gear ring on one device on lathe, process flow is reduced, simplifies operation Process and difficulty of processing improve processing efficiency.

In order to achieve the above objectives, the utility model provides the following technical solutions:

A kind of signal gear ring hobber structure, including rack, hobboing cutter case, pedestal, knife bar, hobboing cutter and milling cutter；The hobboing cutter case Rack or more two sides are respectively arranged at pedestal；The knife bar is extended downwardly by hobboing cutter case, the bottom end rotation connection of the knife bar In on pedestal, and knife bar can rotate under the drive of hobboing cutter case and alter up and down knife；The hobboing cutter and milling cutter respectively have one, are all connected with and set It is placed on knife bar.

Preferably, the knife bar, which is detachably fixed, is mounted in the middle part of hobboing cutter case, fixed peace on the outer wall of the knife bar upper end Equipped with external screw thread, the internal screw thread with external screw thread cooperation, the knife bar and hobboing cutter case spiral shell are installed in the middle part of hobboing cutter bottom portion Line connection.

Preferably, the knife bar is integrally formed the middle part for being mounted on hobboing cutter bottom end.

Preferably, the hobboing cutter, milling cutter with knife bar tight fit.

Preferably, the distance between the hobboing cutter and milling cutter are adjustable.

Preferably, the hobboing cutter is any one high-speed steel in W18Cr4V, W9Mo3Cr4V, W6Mo5Cr4V2.

Preferably, the milling cutter is face milling cutters.

The utility model has the beneficial effects that: the utility model by connecting hobboing cutter and milling simultaneously on a knife bar Knife concentrates on gear hobbing, mill teeth on lathe as soon as realizing, and completes the gear hobbing of signal gear ring on one device, mill teeth is made Industry reduces process flow, simplifies operational sequence and difficulty of processing, improves processing efficiency.

Detailed description of the invention

In order to keep the purpose of this utility model, technical scheme and beneficial effects clearer, the utility model provides as follows Attached drawing is illustrated:

FIG. 1 is a schematic structural view of the utility model；

Fig. 2 is the signal gear ring structure schematic diagram completed after processing.

It is marked in attached drawing as follows: rack 1, hobboing cutter case 2, pedestal 3, knife bar 4, hobboing cutter 5, milling cutter 6, signal gear ring 7.

Specific embodiment

Below in conjunction with attached drawing, the preferred embodiment of the utility model is described in detail.

Such as Fig. 1, a kind of signal gear ring hobber structure, including rack 1, hobboing cutter case 2, pedestal 3, knife bar 4, hobboing cutter 5 and milling cutter 6；The hobboing cutter case 2 and pedestal 3 are respectively arranged at about 1 two sides of rack；The knife bar 4 is extended downwardly by hobboing cutter case 2, and bottom end turns It is dynamic to be connected to pedestal 3, and knife bar 4 can rotate under the drive of hobboing cutter case 2 and alter up and down knife；The hobboing cutter 5 and milling cutter 6 respectively have one Being all connected with and be set on knife bar 4.

In use, first with hobboing cutter 5 by signal gear ring 7 to be processed institute it is with teeth process, then knife bar 4 is altered knife and is exchanged with Milling cutter 6, corner mill away hypodontia part by cyclic process, and then workbench (not shown) drives signal gear ring 7 to rotate Then certain angle processes duplicate removal slot part so that duplicate removal slot part is needed to be directed at milling cutter 6, the letter after completing processing Number gear ring structure such as Fig. 2.

So far, as soon as the present embodiment realizes concentrates on gear hobbing, mill teeth on lathe, signal is completed on one device Gear hobbing, the mill teeth operation of gear ring reduce process flow, simplify operational sequence and difficulty of processing, improve processing efficiency.

Further, the hobboing cutter that the present embodiment uses is high for any one in W18Cr4V, W9Mo3Cr4V, W6Mo5Cr4V2 Fast steel.In signal gear ring process, the effect and abrasion of load are absorbed impact, therefore hardness requirement reaches 63- 66HRC can meet processing request using above-mentioned high-speed steel.

Further, the milling cutter 6 that the present embodiment uses is face milling cutters, its main feature is that high production efficiency；Rigidity is good, can use The biggish amount of feeding；There are multiple cutters tooth to participate in cutting simultaneously, work smoothness are good；Adopt rigid inserted structure, the sharpening of cutter tooth, replacement Convenient, cutter life is long.

Finally, it is stated that preferred embodiment above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, to the greatest extent Pipe has been described in detail the utility model by above preferred embodiment, but those skilled in the art should manage Solution, can make various changes, without departing from the utility model claims book institute to it in the form and details The range of restriction.
