Technical field
The utility model relates to the machining equipment field of broaching spiral internal gear, helical spline, is a kind of broacher of processing two drive-types of spiral internal gear, helical spline.
Background technology
It is big that spiral internal gear, helical spline have a driving torque than spur gear and common spline, advantages such as stable drive, extensive use in the automotive transmission now.The processing of spiral internal gear, helical spline is the bigger Broaching Technology of difficulty, on common in the market broaching machine, can't directly broach, and the price of numerical control broaching machine is very expensive, and general medium-sized and small enterprises are bought the restriction that funds and investment repayment are arranged.Therefore be badly in need of occurring lower, the two broachers that drive of inside spin tooth effective, long service life of broaching of a kind of cost.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, provides a kind of cost lower, the two broachers that drive of inside spin tooth effective, long service life of broaching, and satisfies the production demand.
The utility model solves the technical scheme that its technical problem adopts: the two broachers that drive of this inside spin tooth; Comprise lathe, the lathe middle section position is fixed with the work mounting s seat, and work mounting s seat left side is provided with left supporting seat; Work mounting s seat right side is provided with right supporting seat; Left side supporting seat, right supporting seat all slide and are arranged on the lathe, and the work mounting s seat is provided with through hole, is provided with spiral guide pillar, broaching tool between left supporting seat and the right supporting seat; The transmission of spiral guide pillar is bolted on the work mounting s seat, and broaching tool is arranged in the through hole; The spiral guide pillar rotates through the gear drive broaching tool.Like this; The spiral guide pillar rotates broaching tool through gear drive when straight line moves; Can make more steady reliable, the bigger possibility appearance that can prevent effectively that also the less broaching tool of diameter from being twisted off of transmission moment of torsion of broaching, obviously improve the service life of equipment, thereby reduce cost; The spiral guide pillar can adopt the high-strength materials manufacturing, and result of use can be better.
Further, left supporting seat one side is provided with spiral guide pillar chuck, pulling chuck, and spiral guide pillar one end is arranged in the spiral guide pillar chuck, and broaching tool one end is arranged in the pulling chuck.Like this, come clamping spiral guide pillar and broaching tool, can be convenient to withdrawing clamping workpiece to be processed, can obviously increase work efficiency during use through spiral guide pillar chuck, pulling chuck.
Further, gear comprises front gear, backgear; Front gear, backgear all have two, and front gear is individually fixed on spiral guide pillar chuck, the pulling chuck, and backgear is individually fixed in the other end of spiral guide pillar, broaching tool.Like this, the utilization through two pairs of travelling gears can make that stable drive is reliable, to transmit moment of torsion bigger, effectively avoids the less broaching tool of diameter to be twisted off, and has enlarged the scope of apparatus processing size.
Right supporting seat is provided with top, and the rigidity and the stable working property of spiral guide pillar and broaching tool can be improved so all through top support in the end of spiral guide pillar and the end of broaching tool, improves machining accuracy.
The effect that the utility model is useful is: the utility model rational in infrastructure, compact, through spiral guide pillar, broaching tool and before back-geared reasonable setting, can effectively solve a broaching difficult problem of on plane bench, carrying out spiral internal gear or helical spline; Two pairs of gears rotated broaching tool before and after the utility model adopted when straight line moves, and two pairs of gears can make stable drive reliable, made the transmission moment of torsion more greatly also can prevent effectively that the less broaching tool of diameter from being twisted off.The utility model cost is lower, easy maintenance, and service life is higher, and it is effective to broach, and is worthy of popularization.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
With reference to accompanying drawing: the two broachers that drive of this inside spin tooth in the present embodiment; Comprise lathe 1; Lathe 1 middle section position is fixed with work mounting s seat 2, and work mounting s seat 2 left sides are provided with left supporting seat 3, and left supporting seat 3 one sides are provided with spiral guide pillar chuck 9, pulling chuck 10; Work mounting s seat 2 right sides are provided with right supporting seat 4; Right supporting seat 4 is provided with top 11; Left side supporting seat 3, right supporting seat 4 all slide and are arranged on the lathe 1, and work mounting s seat 2 is provided with through hole 5, is provided with spiral guide pillar 6, broaching tool 7 between left supporting seat 3 and the right supporting seat 4; Spiral guide pillar 6 one ends are arranged in the spiral guide pillar chuck 9, and broaching tool 7 one ends are arranged in the pulling chuck 10; 6 transmissions of spiral guide pillar are bolted on the work mounting s seat 4, and broaching tool 7 is arranged in the through hole 5; The end of the end of spiral guide pillar 6 and broaching tool 7 is all supported through top 11; Spiral guide pillar 6 drives broaching tool 7 through gear 8 and rotates; Gear 8 comprises front gear 8-1, backgear 8-2; Front gear 8-1, backgear 8-2 all have two, and front gear 8 is individually fixed on spiral guide pillar chuck 9, the pulling chuck 10, and backgear 8-2 is individually fixed in the other end of spiral guide pillar 6, broaching tool 7.
When the utility model uses; Workpiece to be processed 12 is clamped in through hole 5 outer ends on the work mounting s seat 2; Select the broaching tool 7 of corresponding specification and the spiral guide pillar 6 that is complementary with broaching tool 7 according to the processing needs; During installation broaching tool 7 feed ends are passed workpiece 12 and dock fixingly with pulling chuck 10, spiral guide pillar 6 dock with spiral guide pillar chuck 9 simultaneously to be fixed; Then spiral guide pillar 6 rotates on the following limit of moving of the effect of lathe 1 main shaft; When spiral guide pillar 6 rotates; Can drive broaching tool 7 through front gear 8-1, backgear 8-2 and rotate, the helical pitch of spiral guide pillar 6 is identical with the spiral internal gear helical pitch of workpiece to be machined 12 like this, and rotation direction is opposite; During work, broaching tool 7 also turn to the switched in opposite with spiral guide pillar 6.The two pairs of gears can make that transmission is more steadily reliable, to transmit moment of torsion bigger and can prevent effectively that the less broaching tool of diameter 7 from being twisted off.The utility model result of use is good, long service life, and also cost is lower, is worthy to be popularized.
