Description
Technical field
The utility model relates to the mechanism of the relevant mill rotating shaft lifting in the polishing machine, particularly polishing machine that building boards such as wall floor tile are polished.
Background technology
The mill rotating shaft elevating mechanism of polishing machine, comprise the fixed mount that is fixed on the polishing machine frame, be fixed on the lifting driver on the fixed mount, and mill rotating shaft, the supporting seat that has radially shaken main effect of contraction to the mill rotating shaft of erectting, the mill rotating shaft is enclosed within the supporting seat rotationally.In existing polishing machine, above-mentioned supporting seat is fixed on the frame motionless, be the requirement of satisfying that the mill rotating shaft can be rotated and can lifting, draw bail between mill rotating shaft and the supporting seat not only will satisfy the rotation connecting relation, also to satisfy the relation of being slidingly connected, so just make that the draw bail between mill rotating shaft and the supporting seat is comparatively complicated.And supporting seat is bearing the radially shock load of mill rotating shaft in the polishing machine course of work, and it is heavier to load.So existing polishing machine is after work a period of time, just make mill rotating shaft and the generation of the draw bail between supporting seat wearing and tearing in the mill rotating shaft elevating mechanism loosening easily, in case take place loosening, can aggravate the radially vibrations of mill rotating shaft again conversely, form vicious circle, greatly shortened the service life of mill rotating shaft elevating mechanism.For this reason, existing polishing machine all has to limit the rotating speed of mill, generally is controlled at 400～1000 rev/mins, and under this slow-speed of revolution, the mill utilization rate is lower, and polishing effect is undesirable.
Summary of the invention
The purpose of this utility model is the defective at above-mentioned polishing machine, and a kind of more durable polishing machine mill rotating shaft elevating mechanism is provided.
The utility model is achieved in that the mill rotating shaft elevating mechanism of polishing machine comprises the fixed mount that is fixed on the polishing machine frame, is fixed on the lifting driver on the fixed mount, and mill rotating shaft, a supporting seat that has radially shaken main effect of contraction of erectting to the mill rotating shaft, the mill rotating shaft is enclosed within the supporting seat rotationally, especially, mill rotating shaft axial restraint in supporting seat, supporting seat and fixed mount slide up and down and connect and by the lifting driver drives.Polishing machine when work, the mill rotating shaft can freely be rotated in supporting seat, when needs mill rotating shaft lifting, by lifting driver drives supporting seat, again by supporting seat drive rotating shaft one lifting, has satisfied the requirement that the mill rotating shaft should be rotated lifting again thus.This shows, the utility model is retrained with the elevating movement branch rotation of mill rotating shaft by different members, make the draw bail between mill rotating shaft and the supporting seat no longer need to satisfy the rotation connecting relation simultaneously and be slidingly connected relation, draw bail is simplified, can improve supporting seat thus and bear the holding capacity that the mill rotating shaft radially shakes, thus the durability of raising mill rotating shaft elevating mechanism.
The utility model has the advantages that: owing to improved the supporting seat holding capacity that rotating shaft radially shakes to mill, so the rotating speed of mill can bring up to more than 1450 rev/mins, thereby improves the mill utilization rate, promotes quality of finish; Have again, because between supporting seat and the mill rotating shaft is axial restraint, so the weight of supporting seat can be delivered on the mill by rotating shaft, and the increasing mill is to the pressure of work piece, thereby can reduce the originally required Pneumatic pressure of mill, reduce the operating cost of polishing machine.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Referring to Fig. 1, Fig. 2, the mill rotating shaft elevating mechanism of polishing machine comprises the fixed mount 2 that is fixed on the polishing machine frame 1, is fixed on the lifting driver 3 on the fixed mount 2, and the mill rotating shaft of erectting 4, the supporting seat that has radially shaken main effect of contraction 5 to the mill rotating shaft, mill rotating shaft 4 is enclosed within the supporting seat 5 rotationally.Mill rotating shaft 4 is axial restraint in supporting seat 5, and supporting seat 5 and fixed mount 2 slide up and down and connect and driven by lifting driver 3.
Rotation between mill rotating shaft 4 and the supporting seat 5 and axial restraint structure, preferably as shown in Figure 2, supporting seat 5 is sleeves concentric with mill rotating shaft 4, be fixed with rolling bearing 6 between rotating shaft 4 and supporting seat 5 inwalls, the inwall of the outer ring of rolling bearing 6 and supporting seat 5 is fixed, inner ring and rotating shaft 4 is fixing, constitutes thus that mill rotating shaft 4 connects with rotation between the supporting seat 5 and axial restraint concerns.
Preferred forms as draw bail between supporting seat 5 and the fixed mount 2, the fixed mount 2 of present embodiment is a hollow cylinder, supporting seat 5 is enclosed within the fixed mount 2, be with location shock absorbing ring 7 between fixed mount 2 and the supporting seat 5, symmetry offers the chute 8 of two settings on fixed mount 2, on supporting seat 5, be symmetrically fixed with two slide blocks 9, two slide blocks 9 are enclosed within two chutes 8 slidably, 9 pairs of supporting seats 5 of slide block play radial location and axially directed effect, constitute the relation that is slidingly connected between supporting seat 5 and the fixed mount 2 thus.
As the preferred forms of lifting driver, the lifting driver 3 of present embodiment is a cylinder, and the piston rod 10 of cylinder is connected with slide block 9 on being fixed on supporting seat 5, and cylinder 3 drives supporting seats 5 liftings by piston rod 10.In addition, lifting driver 3 also can adopt hydraulic cylinder to replace cylinder, perhaps adopts motor.If the lifting driver 3 among Fig. 2 is motors, then can change the piston rod among the figure 10 into screw mandrel, and with slide block 9 as nut, constitute screw mandrel-nut transmission mechanism, just can drive supporting seat 5 oscilaltions when screw mandrels 10 rotate when the motor 3 as the lifting driver drives.
The main motor 11 that present embodiment will drive mill rotating shaft rotation is fixed on the fixed mount 2, connect by axle sleeve 13 between motor shaft 12 and the mill rotating shaft 4, transmit torsion by axle sleeve 13, connect by slip flat key (also can be spline) between axle sleeve 13 and the mill rotating shaft 4, mill rotating shaft 4 can be slided in axle sleeve 13, axle sleeve 13 connects with a fixed cover 15 by bearing 14, fixed cover 15 is fixing with fixed mount 2, and be slidingly matched with supporting seat 5, be fixed with sliding bearing 16 between supporting seat 5 and the fixed cover 15, sliding bearing 16 plays the effect that reduces frictional force between supporting seat 5 and the fixed cover 15, and certain cushioning effect, sliding bearing 16 are arranged can be a copper sheathing or make with other elastomeric materials.In order to reduce the vibrations between mill 17 and the rotating shaft 4, between rotating shaft 4 and mill 17, damping rubber cushion 18 shown in Figure 2 should be installed, make rotating shaft 4 form flexible the connection with mill 17.
