Abstract

The utility model discloses a kind of tandem fine module gear solid hob, including knife bar and the hobboing cutter cutter hub for being arranged on knife bar and being connected as one with knife bar, two or more equidistant annular isolation grooves are set on hobboing cutter cutter hub, and annular isolation groove isolates hobboing cutter cutter hub to form multiple independent hobboing cutters being cascaded.The fine module gear solid hob of the utility model is integrated with installation knife bar in series due to each relatively independent hobboing cutter, the accessories such as knife bar, packing ring, clamp nut need not be installed when in use, this not only reduces the installation error of hobboing cutter, also reduces use cost.And after disposable clamping the relatively independent hobboing cutter that each is cascaded on hobboing cutter cutter hub can be used to carry out Roughing and fine machining to Same Part, element precision is stablized after making processing, overcomes the deficiency of existing Gear Hob with Small Modulus.

Description

A kind of tandem fine module gear solid hob
Technical field
A kind of tandem fine module gear solid hob is the utility model is related to, belongs to cutter for gear wheel manufacturing technology and makes Use field.
Background technology
At present, the cutting edge partial-length of conventional Gear Hob with Small Modulus is respectively less than 30mm, is subtracting with cutter module It is small and gradually reduce it is short, this is because in Gear Hob with Small Modulus process, after relief grinding hobboing cutter top relief angle and side edge During angle, since the abrasive particle of Grinding wheel comes off and blunt naturally, hobboing cutter axial pitch bigger error can be caused, so, in order to ensure The accuracy of manufacture of Gear Hob with Small Modulus, the maximum length of cutting edge part are usually no more than 30mm, also, current low module Gear hob is during manufacture and use, using mesoporous location and installation, the drawback is that:The length of the cutting edge part of hobboing cutter It is limited, that is, hobboing cutter altering knife number and can accordingly reduce in use, which increase hobboing cutter tool changing and reface frequency Rate, reduces production efficiency;Meanwhile Gear Hob with Small Modulus is during manufacture and use, with mesoporous location and installation, it is necessary to There are the accessories such as corresponding installation knife bar, packing ring, clamp nut, not only add the use cost increase of hobboing cutter, can also make hobboing cutter Installation error increase, reduce the accuracy of manufacture of fine module gear.
Utility model content
The purpose of this utility model is:A kind of simple in structure, low manufacture cost, quick for installation, high precision machining is provided Tandem fine module gear solid hob, with overcome the deficiencies in the prior art.
A kind of tandem fine module gear solid hob of the utility model, including knife bar and be arranged on knife bar and with The hobboing cutter cutter hub that knife bar is connected as one, sets two or more equidistant annular isolation grooves on hobboing cutter cutter hub, Annular isolation groove isolates hobboing cutter cutter hub to form multiple independent hobboing cutters being cascaded.
Further, each relatively independent hobboing cutter is by rake face, top relief angle, side edge, helicla flute and chip pocket structure Into.
Further, the rake face of each relatively independent hobboing cutter is on same plane in the axial direction.
By adopting the above-described technical solution, the utility model has the advantage of:The utility model makes tandem low module During fabrication, the length of cutting edge part can be added gear solid hob according to the maximum moving distance of selected gear hobbing machine knife frame Long, maximum can be lengthened to 100mm, can make hobboing cutter in use, reduced tool changing and refaced frequency, improve production efficiency.Together When, the fine module gear solid hob of the utility model is in series with installing knife bar due to each relatively independent hobboing cutter It is integrated, the accessories such as knife bar, packing ring, clamp nut need not be installed when in use, this not only reduces the installation of hobboing cutter Error, also reduces use cost.And the phase that each is cascaded on hobboing cutter cutter hub can be used after disposable clamping Roughing and fine machining is carried out to Same Part to independent hobboing cutter, element precision is stablized after making processing, overcomes existing fine module gear The deficiency of hobboing cutter.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model;
Fig. 2 is the Section A-A figure of Fig. 1.
Description of reference numerals:1- knife bars, 2- hobboing cutter cutter hubs, 3- annular isolation grooves, 4- rake faces, 5- top relief angles, 6- sides Sword, 7- helicla flutes, 8- chip pockets.
Embodiment
It is right with reference to the accompanying drawings and examples in order to make the purpose of this utility model, technical solution and advantage clearer The utility model is described in further detail.
The embodiment of the utility model:Structure diagram such as Fig. 1 and Fig. 2 institutes of tandem fine module gear solid hob Show, including knife bar 1 and the hobboing cutter cutter hub 2 that is arranged on knife bar 1 and is connected as one with knife bar 1, set on hobboing cutter cutter hub 2 Three equidistant annular isolation grooves 3, annular isolation groove 3 isolate hobboing cutter cutter hub 2 to form four independences being cascaded Hobboing cutter.Each relatively independent hobboing cutter is formed by rake face 4, top relief angle 5, side edge 6, helicla flute 7 and chip pocket 8. The rake face 4 of each relatively independent hobboing cutter is on same plane in the axial direction.
Tandem fine module gear solid hob when in use, the installation method one of its mounting means and common hob arbor Cause, the taper shank part of knife bar 1 couples with the tool spindle hole of gear-hobbing machine, the cylindrical place in 1 front end of knife bar and gear-hobbing machine knife bar bracket hole Coordinate.When processing gear part, can be opened from the left side of four relatively independent hobboing cutters or first of the right being cascaded Begin to use, after first relatively independent hobboing cutter cutter tooth is all worn, can wouldn't change reconditioning, only need to be by gear hobbing machine knife frame axis To the width distance of a mobile annular isolation groove 3, such second relatively independent hobboing cutter can begin to use, according to above-mentioned Method, until after four relatively independent hobboing cutters are all worn, changes reconditioning, and reduce hobboing cutter changes number and reconditioning frequency Rate, improves production efficiency.
When carrying out the Roughing and fine machining of gear tooth using tandem fine module gear solid hob, if opposite from four The left side of independent hobboing cutter or the first of the right begin to use, then first relatively independent hobboing cutter is used as roughing, second Relatively independent hobboing cutter is just finished, and after the completion of roughing, the knife rest of gear-hobbing machine moves axially a relatively independent rolling The length of knife, second relatively independent hobboing cutter can be finished.
After rough machined hob abrasion is used as first, knife rest one relatively independent hobboing cutter of axial movement of gear-hobbing machine Length, second relatively independent hobboing cutter that original is used as finishing can be used as roughing and use, and the 3rd relatively independent rolling Knife is then finished, and so on, each relatively independent hobboing cutter can be made full use of, meanwhile, according to said method into Row finishing hobboing cutter blade used remains most sharp state, this can stablize the accuracy of gear after processing.
