Detailed description of the invention
In order to the technical solution of the utility model is explained further, below by specific embodiment, this utility model is entered
Row elaborates.
As Figure 1-3, it is a kind of vertical machining centre shaft bearing screw rod transmission structure of this utility model announcement,
Including saddle 1, screw mandrel 2, feed screw nut 3, head shaft bearing 4a, tail bearing seat 4b, drive motor 5, integrated bearing 6 and lock
Jack panel 7.
Saddle 1, head shaft bearing 4a and tail bearing seat 4b are integrally cast, and eliminate head shaft bearing 4a and afterbody
The set-up time of bearing block 4b.The two ends of screw mandrel 2 are arranged on head shaft bearing 4a and tail bearing by integrated bearing 6 respectively
On seat 4b.Feed screw nut 3 is arranged on screw mandrel 2, connects for fixing with workbench (not shown).Saddle 1 is provided with for work
The line rail 11 that station is slided, line rail 11 is parallel with screw mandrel 2.
Drive motor 5 to be fixedly mounted in saddle 1, after the extended tips bearing block 4a of screw mandrel 2 one end, pacified by shaft coupling 8
It is contained on the motor shaft driving motor 5, to ensure the stationarity of transmission.Motor 5 is driven to drive screw mandrel 2 to rotate, screw mandrel 2 band movable wire
Stem nut 3 moves, and feed screw nut 3 then drives on the online rail of workbench 11 and moves.
Head shaft bearing 4a and tail bearing seat 4b are provided with the anticollison block towards feed screw nut 3, to prevent feed screw nut 3
Mobile ultralimit position, and rigid impact head shaft bearing 4a or tail bearing seat 4b, cause the damage of part.
As shown in Figure 4, wherein the two ends of screw mandrel 2 form axle journal 21 respectively, and the inner of axle journal 21 is used for installing integral shaft
Hold 6.The outer end of axle journal 21 forms the diameter external screw thread 22 less than or equal to axle journal 21 the inner, and locking nut 7 is arranged on external screw thread
For the inner ring of the formula bearing 6 that is fixed as one on 22.
Integrated bearing 6 includes one mounted bearing block main body 61, bearing 62, gland 63, sealing ring 64 and in advance
Sleeve 65.
Bearing block main body 61 is T-shaped axle sleeve, and head shaft bearing 4a and tail bearing seat 4b offer and pacify for bearing block main body 61
The axis hole 41 of dress, the diameter of the outer rim 611 of T-shaped axle sleeve is more than the diameter of axis hole 41.
Bearing 62 is arranged in bearing block main body 61.The outer end of bearing block main body 61 is provided with gland 63, and gland 63 is used for
It is fixed the outer ring of bearing 62.
The two ends of bearing 62 inner ring are fixed by the sleeve 65 consistent with inner ring internal diameter, and two sleeves 65 are in the axle of axle journal 21
Between shoulder 211 and locking nut 7, inwardly promoted sleeve 65 by locking nut 7, thus sleeve 65 be pressed on the shaft shoulder 211,
Complete the fixing of bearing 62 inner ring.Between sleeve 65 and gland 63, and it is mounted between sleeve 65 and bearing block main body 61
Sealing ring 64.
During installation, first screw mandrel 2 is located on head shaft bearing 4a and tail bearing seat 4b.The most successively by integrated bearing
6 are set on the axle journal 21 of screw mandrel 2, and are arranged in two axis holes 41.Then by locking nut 7 precession screw mandrel 2, clamp sleeve
65, complete the installation of bearing.Owing to itself having certain adjustment amplitude between bearing 62 inner ring and outer ring, therefore by fine setting
Locking nut 7, can complete the prestretching between screw mandrel and bearing and locking rectification, thus completes the accurate of bearing 62 and screw mandrel 2
Install.
The two ends of screw mandrel 2 are separately mounted to the head of saddle 1 by integrated bearing 6 and locking nut 7 by the present embodiment
On bearing block 4a and tail bearing seat 4b, structure is simpler.
During adjustment, only need to adjust the dynamics that locking nut 7 screws, install very convenient, reduce installation personnel
Technology requirement, accelerate lathe production process.
Owing to only screwing locking nut 7 during mounting and adjusting, when therefore installing, the impact suffered by parts is few, there is not primitive axis
Hold to be difficult to install and cause bearing to block and make component surface form the problem that stealth is burnt, it is ensured that what screw mandrel 2 ran stablizes
Property, improve the stability of machine tooling quality.
These are only preferred embodiment of the present utility model, the not restriction to protection domain of the present utility model.All depend on
