Abstract
The utility model discloses a lifting mechanism for a heat preservation furnace. The lifting mechanism comprises two rectangular lifting top plates arranged side by side, wherein the bottoms of the left end and the right end of each lifting top plate are respectively connected with a lifting screw rod mechanism; the lower ends of the lifting screw rod mechanisms are connected with speed change boxes; worm wheel and worm mechanisms are arranged in the speed change boxes and are used for driving the lifting screw rod mechanism; two worm wheel and worm mechanisms corresponding to each lifting top plate are connected by a connection shaft of the corresponding speed change box in a transmission manner; the speed change box correspondingly arranged below the left side of each lifting top plate is respectively provided with the connection shaft for driving worm wheel and worm mechanism; the two connection shafts are driven to rotate by the same motor; and the lifting top plates are guided to lift by guide mechanisms. The lifting mechanism executes lifting in a worm wheel and worm mode; worm wheels and worms have self-locking functions; two guide sleeves are respectively arranged on two sides of the mechanism; in the process, under the action of the guide sleeves and guide columns, the heat preservation furnace is precisely lifted and is accurately and quickly matched and linked with a casting machine; and a phenomenon of lifting deviation caused by position difference is avoided.
Description
Technical field
The utility model relates to the holding furnace elevating mechanism.
Background technology
In low-pressure casting process, in the past holding furnace lifting mainly is to carry out lifting by oil cylinder, in this process, owing to the difference of the oil pressure between the leakage of oil in the oil cylinder and each oil cylinder etc. reason, tend to cause the slight inclination that produces gap or holding furnace between holding furnace and the casting die, affect the casting pressure of product, the accidents such as the aluminium hydrorrhea has perhaps occur in smoothly moulding.Especially in the double air injection machine, because the tonnage of holding furnace is heavier, and two casting machines share holding furnaces, therefore the elevating mechanism of this holding furnace becomes more important.
The utility model content
Technical problem to be solved in the utility model just provides a kind of holding furnace elevating mechanism, and lifting process is reliable and stable.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the holding furnace elevating mechanism, it is characterized in that: comprise two rectangle lifting top boards side by side, bottom, two ends, the every lifting top board left and right sides connects respectively an elevating screw mechanism, described elevating screw mechanism lower end connects gearbox, be provided with worm-and-wheel gear in the gearbox and drive elevating screw mechanism, between two worm-and-wheel gears corresponding to every lifting top board by gearbox connecting axle connection for transmission, the gearbox that correspondence is arranged on below, lifting top board left side is respectively equipped with connecting axle driving worm-and-wheel gear, described two connecting axles drive rotation by same motor, and described lifting top board guides lifting by guiding mechanism simultaneously.
As preferably, described connecting axle end is provided with a pair of intermeshing bevel gear, comprise in this a pair of bevel gear that the driving bevel gear of fixing with connecting axle reaches and drive the bevel gear that is connected of bevel gear engagement, be fixedly connected with by a control major axis between two connection bevel gears, motor connects one of them by shaft coupling and drives bevel gear.
As preferably, described gearbox is fixed on the lifting base plate of lifting floor below, described lifting floor below is provided with column and supports, described guiding mechanism comprises guide pillar and the corresponding lifting guide pin bushing that is fixed on the lifting base plate that vertically is fixed in respectively below, the lifting top board left and right sides, the lifting in the lifting guide pin bushing of described guide pillar.
As preferably, described guide pillar lower end is connected and fixed by a plate.
As preferably, fix an auxiliary cylinder in the middle part of the described lifting base plate and drive the lifting top board.
As preferably, described lifting top board is provided with that limit switch connects and the control motor.
The utility model adopts the mode of worm and gear to carry out lifting, be provided with two lifting guide pin bushings and an auxiliary cylinder, worm and gear has the effectiveness of self-locking, can be not autonomous after namely rising offset downward etc., respectively be provided with two guide pin bushings in the both sides of this mechanism, in this process because the effect of guide pin bushing guide pillar, the lifting of holding furnace is more accurate, cooperating with the casting board of accurate quick is online, the lifting deviation that can not produce owing to the difference of position degree, and be provided with auxiliary cylinder at the stressed middle part of this elevating mechanism, increased holding furnace to whole elevating mechanism, simultaneously also play the holding capacity of sharing the both sides elevating screw, make its safety and reliability, the life-span is longer.
