Description

Vertical-horizontal conversion swing mechanical main shaft

Technical Field

The utility model relates to a change yaw mechanical spindle crouches immediately.

Background

At present, for domestic and foreign high-grade machining centers, a milling functional part is generally formed by an electric spindle. The electric spindle machining center generally has the advantages of small cutting torque, small feed amount, long machining time for machining workpieces with large cutting amount, low machining efficiency and incapability of meeting market requirements.

SUMMERY OF THE UTILITY MODEL

The utility model provides a technical problem overcome prior art not enough, provide one kind and can carry out the big cutting volume and the conversion yaw mechanical spindle that crouches immediately of fly-cutting.

The utility model discloses a technical scheme be the conversion yaw machinery main shaft of crouching immediately, torque motor drives gear shaft rotation through intermeshing's initiative spiral bevel gear and driven spiral bevel gear, and the gear shaft meshes with the gear wheel among the epaxial double toothed disc of integral key, and integral key shaft axial displacement can be followed to the double toothed disc, and gear wheel accessible meshes the drive spindle rotation with main shaft front gear mutually, and the pinion accessible on the double toothed disc meshes the drive spindle rotation with main shaft rear gear mutually. The spline shaft is also provided with a gear shifting mechanism. When the large gear is meshed with the front gear of the main shaft, the rotating speed of the main shaft is increased, the torque is reduced, and the fine machining operation with small cutting amount is suitable; the gear shifting mechanism pushes the double gear disc to move axially along the spline shaft, the large gear is disengaged from the front gear of the main shaft and is not meshed any more, and when the small gear is meshed with the rear gear of the main shaft, the rotating speed of the main shaft is reduced, the torque is increased, and the gear shifting mechanism is suitable for large cutting amount and rough machining operation.

The beneficial effects of the utility model are that a change yaw mechanical spindle crouches immediately with two grades of regulatory functions is provided, both can carry out the rough machining of big cutting output, fly-cutting, also can carry out the finish machining of high accuracy cutting.

Detailed Description

Found conversion yaw machinery main shaft crouches, torque motor 1 drives gear shaft 4 through intermeshing's initiative spiral bevel gear 2 and driven spiral bevel gear 3 and rotates, and gear shaft 4 meshes with big gear 51 in the double toothed disc 5 on the integral key shaft 8, and double toothed disc 5 can be followed integral key shaft 8 axial displacement, and double toothed disc 5 is basically in on two positions, position one: the main shaft 9 is driven to rotate by the large gear 51 on the double gear disc 5 through being meshed with the front gear 6 of the main shaft, and the small gear 52 idles and does not have power output. In the second position, the pinion 52 on the double gear disc 5 is meshed with the main shaft rear gear 7 to drive the main shaft 9 to rotate, the large gear 51 idles, and no power is output. In both positions one and two, the gearwheel 51 of the double gearwheel disc 5 meshes with the gearwheel shaft 4. Spline shaft 8 on still be equipped with and dial tooth mechanism 10, dial tooth mechanism 10 and stir double gear wheel dish between two positions as required, dial tooth mechanism 10's push rod and spline shaft 8 parallel, the axial pull of push rod drives double gear wheel dish 5 and removes along the spline shaft, drive and controlling means are connected to the push rod, according to the space demand, also can adopt the push rod that is not parallel with spline shaft 8. When the large gear 51 is engaged with the front gear 6 of the main shaft, as shown in fig. 1 and 2, the main shaft 9 has high rotating speed and low torque, and is suitable for fine machining operation with small cutting amount; the gear shifting mechanism 10 pushes the double gear wheel disc 5 to move axially along the spline shaft 8, the large gear 51 is disengaged from the front gear 6 of the main shaft and is not meshed any more, and when the small gear 52 is meshed with the rear gear 7 of the main shaft (as shown in fig. 2), the rotating speed of the main shaft 9 is reduced, the torque is increased, and the gear shifting mechanism is suitable for large cutting amount and rough machining operation. Two kinds of operating condition switch in a flexible way, and the cooperation of finish roughing improves machining efficiency greatly.
