Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 and Fig. 2, milling machine of digital-control spiral conical gear workpiece box device, the work spindle 15 comprising workpiece casing 11, servomotor 1 and be arranged on workpiece casing, work spindle two ends are supported by pair of bearings and are arranged on workpiece casing, the change gear gearshift that described workpiece casing one end is fixed with change gear box 7 by screw and is arranged in change gear box.Described change gear gearshift comprises driving gear 2, bevel gear shaft 3, bevel gear 14, straight-tooth wheel shaft 6 and spur gear 16, and described driving gear is directly sleeved on the motor shaft of servomotor 1 by bearing 9, sealing ring 8 and screw 10.Described bevel gear shaft two ends are arranged on change gear box 7 by bearing and ring flange 12, described bevel gear shaft is provided with the bevel gear 14 be meshed with driving gear and the first power shift gear 5 being positioned at tail end by locking nut 4, and described driving gear and bevel gear form bevel gear pair.Described straight-tooth wheel shaft 6 tail end is equipped with the second power shift gear 13 be meshed with the first power shift gear, and the spur gear 16 engaged with straight-tooth wheel shaft is equipped with in described work spindle one end, and forms spur gear pair with straight-tooth wheel shaft.
In the present embodiment, between the motor shaft of described servomotor and driving gear, be provided with the adjusting pad 17 for adjusting driving gear gap.
Operation principle of the present utility model is:
Servomotor 1 and driving gear 2 rotate, and drive bevel gear 14, bevel gear shaft and the first power shift gear 5 engaged with driving gear to rotate, described first power shift gear 5 drives the second power shift gear 13 engaged with it to rotate, and drive straight-tooth wheel shaft 6 to rotate simultaneously, because straight-tooth wheel shaft engages with the spur gear 16 on work spindle 15, and then realize the rotation of milling machine of digital-control spiral conical gear work spindle.
The utility model is by increasing change gear box device at workpiece box back, and the gear pair transmission of work spindle substitutes the transmission of former worm gear, improve the rotating speed of workpiece, and achieve the processing of convergent tooth and equal-depth teeth by the gear pair changing the secondary different drive ratios of gear changing group two.
The embodiment described in the utility model accompanying drawing is exemplary, only for explaining the utility model, and can not be interpreted as restriction of the present utility model.
