Detailed description of the invention
Fig. 1 is a kind of schematic diagram of the four turntable synchronous drive mechanism of vertical machining centre of the utility model；
Fig. 2 is the cross-sectional view in Fig. 1 along long axis；
Fig. 3 is the cross-sectional view of worm screw.
Specific embodiment
As illustrated in fig. 1 and 2, the four turntable synchronous drive mechanism of a kind of vertical machining centre of the utility model, including motor
With the worm screw 9, four of belt wheel 2, belt 6, long axis 3, four worm gear 15, needle bearing 8, combination needle roller being set in turntable body 1
Bearing 11.
Motor rotation drives to belt wheel 2 by belt 6, and belt wheel 2 is fixedly connected with the first end of long axis 3 drives long axis 3 to revolve
Turn, the first end of long axis 3 is supported by needle bearing 8, and the second end of long axis is supported by combination needle bearing 11；Four worm screws
9 are fixedly connected with long axis 3, and four worm gears 15 are engaged with corresponding worm screw 9 respectively, and the rotation of long axis 3 drives worm gear 15 by worm screw 9
Rotation, and then four turntables being separately positioned on four worm gears 15 is driven to rotate synchronously.
When it is implemented, the belt wheel 2 is by 4 tensioner of the first tensioner to realize being fixedly connected between long axis 3.First
Tensioner 4 can satisfy any angle fixed pulley 2.
When it is implemented, four worm screws 9 are respectively by four 10 tensioners of the second tensioner to realize the fixation between long axis 3
Connection.
When it is implemented, driving mechanism is additionally provided with first bearing seat 7 and second bearing seat 12, needle bearing 8 is assemblied in
In one bearing block 7, combination needle bearing 11 is assemblied in second bearing seat 12.The combination needle bearing 11 passes through locking nut
14 lock with second bearing seat 12.The coefficient of friction of needle bearing 8 is small, transmission efficiency is high, mechanical performance with higher and compared with
