Description
Technical field
The present invention relates to gear-hobbing machine technology fox field, be specifically related to a kind of gear-hobbing machine.
Background technology
Gear-hobbing machine is most widely used a kind of lathe in gear cutting machine, can on gear-hobbing machineCutting straight-tooth, helical gears, also can machining worm wheel, sprocket wheel etc.; And common gear-hobbing machine,Operate by artificial processing gimmick, the workpiece processing like this, its precision is low, andManual operation has very large potential safety hazard.
Summary of the invention
For addressing the above problem, the present invention proposes a kind of gear-hobbing machine.
A kind of gear-hobbing machine, speed gears that it comprises the first motor, be connected with the first motor-driven,The worm gear pair being in transmission connection with speed gears, the pawl engaging with worm gear pair wheel, same with pawl wheelMaster gear that axle connects, be arranged on finger cutter directly over master gear, drive finger cutter to turnMoving the second motor, cam, the first roller closing with cam meshing, coordinate company with the first rollerThe spring, the bar that moves up and down that connect, be arranged on the knife rest that moves up and down on bar, connect with cam coaxialThe second roller connecing, the spline shaft being meshed with the second roller, nibble mutually with spline shaftThe 3rd roller that closes, with the coaxial divided teeth gear being connected of the 3rd roller, be meshed with divided teeth gearThe 4th roller; Wherein, described the 4th roller is coaxially connected with worm gear pair.
Described in gear-hobbing machine of the present invention, gear-hobbing machine comprises screw mandrel; Described screw mandrel be arranged on knife rest just underSide.
Described in gear-hobbing machine of the present invention, gear-hobbing machine also comprises the 5th roller; Described the 5th roller andThe motor shaft of one motor coaxially connects and mentions and be meshed with speed.
Gear hobbing described in gear-hobbing machine of the present invention, at cam, the first roller, spring and move up and downUnder bar acting in conjunction, rotating finger cutter pumps with respect to knife rest; Master gear isOne motor, speed gears and worm gear pair rotate under driving; When finger cutter moves up and downWhen speed is identical with master gear reference circle tangential motion linear velocity, its compound motion track is for tiltingThe straight line of 45 °, change cam curve parameter can obtain straight line and the curve of different angle; CamThe finger cutter that rotates a circle is done once to move back and forth; Divided teeth gear makes finger cutter up and down reciprocatingly inferiorNumber is consistent with the institute machining gears number of teeth; Adjusting processed gear tangential position meets revolution markDrawing requirement. Finger cutter uses the first motor, and rotating speed is 2850r/min, and stock-removing efficiency is high,Machined surface roughness is low; By leading screw, knife rest is moved up and down to capable of regulating finger cutter and master gearThe vertical range of end face, to change the cutting depth of vertical direction.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of gear-hobbing machine of the present invention;
