For convenience of description, the two ends of the main shaft 12 are respectively referred to as a first end of the main shaft 12 and a second end of the main shaft 12, the first end of the main shaft 12 extends from the riser 11, and the second end can be located in the riser 11 or extend from the riser 11.

The flange 13 is fixed on the outer wall of the stand pipe 11 and is used for abutting against the machining center or fixedly connecting with the machining center. Of course, the riser 11 can also be connected to a machining center.

The turret 21 is fixedly mounted to a first end of the spindle 12 and is capable of rotating with the rotation of the spindle 12, and the turret 21 is further mounted with a swinging head holder 22, and the swinging head holder 22 is also capable of rotating with the rotation of the turret 21. The spindle 12 rotates in a horizontal direction and the oscillating nose cup 22 rotates in a vertical direction.

The support of the turntable 21 during rotation is achieved by a slide bearing 31, the slide bearing 31 being mounted on the flange 13, and the axis of the slide bearing 31 being in line with the axis of the main shaft 12. The slide bearing 31 can provide sufficient support to the turntable 21 during rotation of the turntable 21.

The adjusting member 32 is mounted on the flange 13 and can abut against the sliding bearing 31, and the adjusting member 32 is used for adjusting the levelness of the turntable 21, for example, when the levelness of the turntable 21 is changed in a heavy load state, the levelness of the turntable 21 can be restored by the adjusting member 32.

For example, the turntable 21 is inclined to a certain angle, which is generally caused by an excessive gravity load in the direction of the angle, and the adjusting member 32 is rotated to apply a pushing force to the sliding bearing 31 by the adjusting member 32, so as to restore the levelness of the turntable 21.

Overall, the double-pendulum milling head vertical turntable provided in the embodiments of the present application can realize the stability of the processing precision in the long-time processing process through an active adjustment manner, and especially in the long-time operation in a certain angle direction, the advantage will be more obvious.

As an embodiment of the double pendulum milling head vertical turntable, the adjusting members 32 are uniformly arranged on the flange 13 around the axis of the main shaft 12, so that adjustment can be performed in multiple directions.

In some possible implementations, the adjusting member 32 is composed of a base and an electric cylinder mounted on the base, the electric cylinder is connected to the control system, and when adjustment is needed, a piston of the electric cylinder abuts against the sliding bearing 31, so that the levelness of the sliding bearing 31 is changed.

Referring to fig. 1, as a specific embodiment of the vertical turntable of the double pendulum milling head provided by the application, a lubricating oil nozzle 41 and an active lubricating unit 42 are further added, the lubricating oil nozzle 41 is installed on the vertical pipe 11, a first end of the lubricating oil nozzle 41 is communicated with a gap at a connection position of the sliding bearing 31 and the turntable 21, and a second end is connected with the active lubricating unit 42.

In the lubricating process, the active lubricating unit 42 injects lubricating oil into the lubricating oil nozzle 41, and after the lubricating oil flows out from the lubricating oil nozzle 41, the lubricating oil flows into a gap at the joint of the sliding bearing 31 and the turntable 21, so as to lubricate the bearing 31 and the turntable 21.

Further, referring to fig. 1 and 2, an annular groove 311 is added to the working surface of the sliding bearing 31, and the first end of the lubricating oil nozzle 41 is communicated with the groove 311, so that the lubricating oil can be fed into the groove 311 for storage. A part of the groove 311 is located between the slide bearing 31 and the turn table 21, and another part is located outside the slide bearing 31 and the turn table 21.

Referring to fig. 3, a liquid level sensor 43 is further installed on the turntable 21, a detection end of the liquid level sensor 43 extends into the groove 311, and a signal output end of the liquid level sensor 43 is connected to a signal input end of the active lubrication unit 42, and is used for detecting the amount of the lubricating oil remaining in the groove 311 and feeding back the amount of the lubricating oil to the active lubrication unit 42.

When the amount of the lubricant remaining in the recess 311 is insufficient, the active lubrication unit 42 is activated to inject a certain amount of lubricant into the recess 311. Wireless communication is used between the level sensor 43 and the active lubrication unit 42.
