Fig. 1 is the schematic diagram of existing vertical miller side-pressing device, as shown in the figure, the side-pressing device of existing vertical miller comprises side pressure screw mandrel 1, side pressure nut 2, support ring 3 and bellows 4, the head of described side pressure screw mandrel 1 is connected with edger roll framework 5, and edger roll framework 5 is used for being connected with edger roll.Described side pressure screw mandrel 1 is threaded with side pressure nut 2, described support ring 3 is enclosed within on the described side pressure screw mandrel 1, support ring 3 is fixed on the vertical miller memorial archway 6, described side pressure nut 2 is fixedlyed connected with described support ring 3, described bellows 4 is enclosed within on the described side pressure screw mandrel 1, the one end is connected with described support ring 3, and the other end is connected with the edger roll framework 5 of side pressure screw mandrel 1 head.Support ring 3 is used for the support of offside silk pressing bar 1, and bellows 4 then is mainly used in dust and water protection.
But there are problems in such oil return mode, and when bellows 4 was shrinking, the oil return pipe 401 on the bellows 4 can be owing on bellows 4 self stacked and stifled, cause a large amount of long-pending oil in the bellows 4, the not insured amount fuel tanks of only getting back to smoothly of lubricating oil.And when bellows 4 stretches, the lubricating oil of getting back in the fuel tank can be sucked back in the bellows 4 again by oil return pipe 401 owing to produce negative pressure in the bellows 4.Be easy to make bellows 4 that bulging take place like this, repeatedly cause bellows 4 breakages after repeatedly.After bellows 4 breakages, on the one hand, inner lubricating oil can leak, and causes unnecessary waste and influences working environment, on the other hand, dust in the surrounding environment and high pressure descaling water etc. all can enter in the bellows 4, the lubricating oil of bellows 4 is contaminated, and after these contaminated lubricating oil enter fuel tank through oil return pipes 401, can make that this vertical miller is intrasystem lubricatedly all to be affected, can cause the vertical miller system in paralyzed state when serious, can't ordinary production.
The utility model content
For addressing the above problem, the utility model provides a kind of vertical miller side-pressing device, effectively the oil return problem of solving device internal lubrication oil.
For achieving the above object, vertical miller side-pressing device of the present utility model, comprise the side pressure screw mandrel, the side pressure nut, support ring and bellows, described side pressure screw mandrel is connected with the side pressure nut thread, described support ring is enclosed within on the described side pressure screw mandrel, described side pressure nut is fixedlyed connected with described support ring, described bellows is enclosed within on the described side pressure screw mandrel, vertical miller side-pressing device of the present utility model also comprises the oil return sleeve pipe, described oil return sleeve pipe is placed on the described support ring, one end of described oil return sleeve pipe is connected with the end of described bellows, the other end is weldingly fixed on the described support ring, and the bottom of described oil return sleeve pipe is provided with first oil return outlet, also is provided with first exhaust outlet on the described oil return sleeve pipe.
The bottom of described support ring is provided with second oil return outlet, also is provided with second exhaust outlet on the described support ring.
Described side pressure nut is other to be provided with nylon nut, and described nylon nut is fixed on the described side pressure nut, and described nylon nut is connected with described side pressure wire rod thread.
Adopt vertical miller side-pressing device of the present utility model, can guarantee the lubricated normal of system, and can prolong the service life of bellows, oil leak can not take place, guarantee that lubricating oil can be not contaminated, thereby guaranteed the normal operation of vertical miller system.

Fig. 2 is the schematic diagram of vertical miller side-pressing device of the present utility model.
The specific embodiment
Fig. 2 is the schematic diagram of vertical miller side-pressing device of the present utility model, as shown in the figure, vertical miller side-pressing device of the present utility model comprises side pressure screw mandrel 10, side pressure nut 20, support ring 30 and bellows 40, the head of described side pressure screw mandrel 10 is connected with edger roll framework 50, and edger roll framework 50 is used for being connected with edger roll.Described side pressure screw mandrel 10 is threaded with side pressure nut 20, described support ring 30 is enclosed within on the described side pressure screw mandrel 10, support ring 30 is fixed on the vertical miller memorial archway 60, and described side pressure nut 20 is fixedlyed connected with described support ring 30, and described bellows 40 is enclosed within on the described side pressure screw mandrel 10.
Vertical miller side-pressing device of the present utility model also comprises oil return sleeve pipe 70, and described oil return sleeve pipe 70 is placed on the described support ring 30,, leave the gap between described oil return casing pipe sleeve 70 and the described support ring 30, be convenient to lubricating oil and flow.One end of described oil return sleeve pipe 70 is connected with the end of described bellows 40, and the other end is weldingly fixed on the described support ring 30.The other end of described bellows 40 is connected with the edger roll framework 5 of side pressure screw mandrel 1 head.The bottom of described oil return sleeve pipe 70 is provided with first oil return outlet 71, also is provided with first exhaust outlet 72 on the described oil return sleeve pipe 70.First oil return outlet 71 is connected with the grease-box of system by oil pipe.After lubricating oil enters bellows 40 with side pressure screw mandrel 10, lubricating oil can flow to oil return sleeve pipe 70, and enter fuel tank from first oil return outlet 71, when bellows 40 stretches, extraneous air can enter oil return sleeve pipe 70 inside from first exhaust outlet 72, therefore can not produce negative pressure, the phenomenon of the lubricating oil in the resorption fuel tank just can not take place.
For avoiding more lubricating oil to enter bellows 40 inside, can make lubricating oil in support ring 30, just directly be discharged into fuel tank, therefore, be provided with second oil return outlet 31 in the bottom of described support ring 30, also be provided with second exhaust outlet 32 on the described support ring 30, second exhaust outlet 32 can effectively be avoided producing negative pressure in the support ring 30, makes the lubricating oil that amasss in support ring 30 can get back to fuel tank smoothly.
Lubricating oil is to side pressure nut 20 and side pressure screw mandrel 10 lubricating oil, and lubricating oil can stick on the side pressure screw mandrel 10 usually, flows to bellows 40 with side pressure screw mandrel 10 then.Enter bellows 40 for reducing lubricating oil, be provided with nylon nut 7 on described side pressure nut 20 sides, described nylon nut 7 is fixed on the described side pressure nut 20, and described nylon nut 7 is threaded with described side pressure screw mandrel 10.Described nylon nut 7 can block the lubricating oil that comes out from side pressure nut 20, also the most of lubricating oil on the side pressure screw mandrel 10 is scraped off simultaneously, and gets back to fuel tank by second oil return outlet 31 of support ring 30 bottoms.
