[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Reference Figure 1-Figure 7: An end gear auxiliary support device for a machine tool milling head, the device comprises: a frame 1, a first drive motor 2, a milling rotating rod 3, a first rotating sleeve 4, a drive gear 5, a second rotating sleeve 6 and a clutch mechanism 7, the milling rotating rod 3 is vertically rotatably arranged on the frame 1, the first drive motor 2 is arranged on the frame 1, and its output shaft is coaxially fixed with the milling rotating rod 3, the first rotating sleeve 4 is coaxially rotatably sleeved on the milling rotating rod 3, the second rotating sleeve 6 is coaxially rotatably arranged below the first rotating sleeve 4, the second rotating sleeve 6 is coaxially surrounded by a plurality of hydraulic grooves 601 facing its axis, each hydraulic groove 601 is coaxially provided with a damping rod 602, the damping rod 602 extends out of the hydraulic groove 601 at one end and abuts against the side wall of the milling rotating rod 3, and its rod body is sleeved with an elastic member 60303, the elastic member 60303 One end of the member 60303 abuts against the inner wall of the hydraulic groove 601, and the other end abuts against the side wall of one end of the damping rod 602 extending into the hydraulic groove 601. A pressure-adjusting threaded rod 603 is coaxially arranged in each hydraulic groove 601, and a rotating gear 604 is coaxially and rotatably arranged on the outer side of the hydraulic groove 601. The rotating gear 604 is coaxially threadedly assembled on the pressure-adjusting threaded rod 603. A limiting groove 60301 is arranged on the threaded portion of the pressure-adjusting threaded rod 603 along its length direction. A limiting block 60101 adapted to the limiting groove 60301 is arranged in the hydraulic groove 601 along its length direction. A driving toothed disc 5 meshing with each rotating gear 604 is coaxially arranged on the first rotating sleeve 4. The clutch mechanism 7 is arranged on the frame 1 to drive the milling rotating rod 3 and the first rotating sleeve 4 to rotate or separate synchronously through the first driving motor 2.

[0033] In the present application, when the first driving motor 2 is started to drive the milling rotating rod 3 to rotate, when the milling rotating rod 3 shakes, the damping rod 602 will be shaken, thereby moving along the axis direction of the hydraulic groove 601, and the elastic member 60303 and the damping fluid in the hydraulic groove 601 will absorb the shaking force, thereby being buffered, and finally the damping rod 602 will gradually reset under the action of the elastic member 60303; when it is necessary to replace the elastic member 60303 and the damping fluid, the clutch mechanism 7 is started to enable the first driving motor 2 to drive the milling rotating rod 3 to rotate. The dynamic milling rotating rod 3 and the first rotating sleeve 4 rotate synchronously, thereby driving the driving gear plate 5 to rotate, and then driving the pressure regulating threaded rod 603 to rotate through the rotating gear 604, thereby adjusting the hydraulic pressure in the hydraulic groove 601. When the pressure regulating threaded rod 603 is screwed out, the user can replace the damping rod 602, the elastic member 60303 and the damping fluid; during use, we start the clutch mechanism 7 so that the first driving motor 2 can only drive the milling rotating rod 3 to rotate, so as to ensure that the machine tool milling head can work normally.

The pressure regulating threaded rod 603 is provided with a pressure regulating plug 60302 adapted to the hydraulic groove 601 at one end close to the damping plug 60201.

[0035] The present application sets a damping plug 60201 to ensure that the damping fluid can flow through the through hole on the damping plug 60201, thereby absorbing the force generated by the vibration of the milling rotating rod 3, and the pressure regulating plug 60302 is to prevent the leakage of the damping fluid.

[0036] Reference Figure 8 : The damping rod 602 is movably provided with a rotating ball head 60202 at one end close to the milling rotating rod 3.

[0037] The present application converts sliding friction into rotational friction by setting a rotating ball head 60202, thereby extending the service life of the machine tool milling head and the damping rod 602.

[0039] The driving toothed disc 5 of the present application is assembled on the spline block 401 of the first rotating sleeve 4 through the first spline groove 501 to ensure that the first rotating sleeve 4 and the driving toothed disc 5 rotate synchronously.

[0041] The second rotating sleeve 6 of the present application is assembled in the first rotating ring groove 402 of the first rotating sleeve 4 through the first rotating ring block 605. At the same time, due to the meshing of the driving gear plate 5 and the plurality of rotating gears 604, the second rotating sleeve 6 is limited and will not rotate.

The driving assembly 703 is arranged on the frame 1 and can drive the first clutch toothed disc 701 to reciprocate along the axis direction of the milling rotating rod 3.

[0045] The present application starts the driving component 703 to drive the first clutch toothed disc 701 to reciprocate along the axis direction of the milling rotating rod 3 to mesh with the second clutch toothed disc 702, thereby realizing the synchronous rotation of the milling rotating rod 3 and the first rotating sleeve 4, and then drives the driving toothed disc 5 to rotate synchronously. The driving component 703 can also be started to drive the first clutch toothed disc 701 to separate from the second clutch toothed disc 702, thereby realizing the independent rotation of the milling rotating rod 3.

[0047] The first clutch gear plate 701 of the present application is coaxially sleeved on the spline shaft 301 of the milling rotating rod 3 through the second spline groove 70101 to ensure that the first clutch gear plate 701 can rotate synchronously with the milling rotating rod 3.

One end of the linkage frame 70303 is sleeved on the first clutch gear plate 701, and the other end is coaxially threadedly assembled on the screw rod 70302.

[0049] In the present application, the second driving motor 70301 is started to drive the screw rod 70302 to rotate, thereby driving the first clutch gear plate 701 to rise and fall synchronously through the linkage frame 70303 to achieve clutch with the second clutch gear plate 702 .

[0050] Reference Figure 4 : A third rotating ring groove 70102 is coaxially arranged on the first clutch gear plate 701, and a third rotating ring block 7030301 adapted to the third rotating ring groove 70102 is coaxially arranged on one end of the linkage frame 70303.

[0051] The linkage frame 70303 of the present application is rotatably assembled in the third rotating ring groove 70102 of the first clutch sprocket 701 through the third rotating ring block 7030301 to ensure that the first clutch sprocket 701 can rotate normally.

[0052] The device provided by the present invention starts the first driving motor 2 to drive the milling rotating rod 3 to rotate. When the milling rotating rod 3 shakes, the damping rod 602 will be shaken, thereby moving along the axis direction of the hydraulic groove 601. The elastic member 60303 and the damping fluid in the hydraulic groove 601 will absorb the shaking force, thereby being buffered. Finally, the damping rod 602 will gradually reset under the action of the elastic member 60303. When it is necessary to replace the elastic member 60303 and the damping fluid, the clutch mechanism 7 is started to make the first driving motor 2 It can drive the milling rotating rod 3 and the first rotating sleeve 4 to rotate synchronously, thereby driving the driving gear plate 5 to rotate, and then driving the pressure regulating threaded rod 603 to rotate through the rotating gear 604, thereby adjusting the hydraulic pressure in the hydraulic groove 601. When the pressure regulating threaded rod 603 is screwed out, the user can replace the damping rod 602, the elastic part 60303 and the damping fluid; during use, we start the clutch mechanism 7 so that the first driving motor 2 can only drive the milling rotating rod 3 to rotate, so as to ensure that the machine tool milling head can work normally.
