Technical problem to be solved by this invention provides a kind of gear shapping machine main motion control device, can realize cutter anxious time, and rate smoothing, and can adjust cutter spacing and stroke easily.
For solving the problems of the technologies described above; The technical scheme that the present invention adopted is: a kind of gear shapping machine main motion control device; Comprise crank and drive crank; Drive crank is rigidly connected through transition axis and transition rocking bar, and transition rocking bar and working beam are slidingly connected, and the bearing of working beam is installed on the frame through apparatus for adjusting position.
In the described apparatus for adjusting position, bearing is slidingly mounted in the mounting, and bearing is connected with the lateral adjustments screw rod;
The end and the transition axis that prop up mounting flexibly connect, and a mounting is provided with worm sector, and worm sector cooperates with rack-mounted vertical adjustment worm screw.
Have an angle between described drive crank and the transition rocking bar, α is 28-32 °.
Described α is 29-31 °.
Transition rocking bar length, crank shaft core to transition axis distance of shaft centers from and drive crank length between ratio be 1:1.4 ~ 1.6:0.85 ~ 1.
Transition rocking bar length, crank shaft core to transition axis distance of shaft centers from and drive crank length between ratio be 1:1.5 ~ 1.6:0.85 ~ 0.95.
Described crank is connected with drive unit through worm-and-wheel gear.
Described working beam one end is provided with knife rest.
A kind of gear shapping machine main motion control device provided by the invention owing to compressed the holding time of inoperative stroke, is compressed to 1/4 with the holding time of inoperative stroke by original 1/2, increases substantially the gear shapping machine stock-removing efficiency.When increasing the impulse stroke holding time, utilize design optimizing that the speed designs of operation interval is minimum for mean square deviation, operating rate is almost at the uniform velocity, and rate curve as shown in Figure 3, obviously improves cutter life near one section straight line.
But through the floating rod mechanism that is provided with; The position and the stroke of adjustment knife rest; Thereby control module---the servo-actuated spool motion state of adjustment hydraulic follow-up knife rest (Chinese patent 201110168593.9) realizes that adjustment cutter shaft reciprocating motion length, cutter shaft move back and forth point midway; Cutter shaft moves back and forth functions such as each stage speed.But use the floating rod output movement to be convenient to adjust lathe cutter shaft reciprocating motion length and reciprocating motion final position and haul distance, the condition in the mechanism is provided for realizing the full-digital control lathe.

Among the figure: crank 1, drive crank 2, working beam 3, knife rest 4, bearing 5, drive unit 6, worm-and-wheel gear 7, transition axis 8, transition rocking bar 9, worm sector 10, vertical adjustment worm screw 11, a mounting 12, lateral adjustments screw rod 13, frame 14.
The specific embodiment
In Fig. 1,4,5 and 6; A kind of gear shapping machine main motion control device comprises crank 1 and drive crank 2, and drive crank 2 is rigidly connected through transition axis 8 and transition rocking bar 9; Transition rocking bar 9 is slidingly connected with working beam 3, and the bearing 5 of working beam 3 is installed on the frame 14 through apparatus for adjusting position.Structure has realized the at the uniform velocity cutting movement of knife rest band quickreturn characteristics thus.
In the described apparatus for adjusting position, bearing 5 is slidingly mounted in the mounting 12, and bearing 5 is connected with lateral adjustments screw rod 13; Structure thus, according to the difference of lateral adjustments screw rod 13 mounting means, when lateral adjustments screw rod 13 and bearing 5 rotatable flexible connections, and a mounting 12 is when being provided with the screw thread that is used to cooperate, and rotation adjusting screw rod 13 is the lateral attitude of scalable bearing 5.Perhaps lateral adjustments screw rod 13 is fixedly connected with bearing 5, and the position of then adjusting the nut on the lateral adjustments screw rod 13 is the lateral attitude of scalable bearing 5, like Fig. 4,5, shown in 6.
One end of mounting 12 flexibly connects with transition axis 8, props up a mounting 12 and is provided with worm sector 10, and worm sector 10 cooperates with vertical adjustment worm screw 11 on being installed in frame 14.Structure is rotated vertical adjustment worm screw 11 thus, then drives worm sector (10) rotation, and 12 of mountings are center of circle rotation with transition axis 8, thus the vertical position of adjustment bearing 5, as shown in Figure 5.
In the scheme of optimizing, have an angle between described drive crank 2 and the transition rocking bar 9, α is 28-32 °.Angle is meant drive crank 2 and transition rocking bar 9, with the perpendicular plane of the axis of transition axis 8 on the angle that forms of projection.
The scheme of further optimizing is: described α is 29-31 °.
Ratio between transition rocking bar 9 length, crank 1 axle center to transition axis 8 axle center distance A and drive crank 2 length is 1:1.4 ~ 1.6:0.85 ~ 1.Crank 1 axle center to the transition axis 8 axle center distance A here are meant, crank 1 axle center and transition axis 8 axle center, and the perpendicular plane of the axis of transition axis 8 on projection between distance.
The scheme of further optimizing is: the ratio between transition rocking bar 9 length, crank 1 axle center to transition axis 8 axle center distance A and drive crank 2 length is 1:1.5 ~ 1.6:0.85 ~ 0.95.Because above-mentioned structural parameters, obtain curve movement as shown in Figure 3, promptly the holding time of inoperative stroke is compressed to 1/4 by original 1/2, increases substantially the gear shapping machine stock-removing efficiency.When increasing the impulse stroke holding time, the speed mean square deviation of operation interval is minimum, and operating rate is almost at the uniform velocity, obviously improves cutter life, improves cutting quality.
Described crank 1 is connected with drive unit 6 through worm-and-wheel gear 7.Described working beam 3 one ends are provided with knife rest 4.Knife rest 4 and hydraulic follow-up knife rest (Chinese patent 201110168593.9) control module---the servo-actuated spool is connected.
