Connection is closed, the leading screw is passed through from worm gear center vertical and screw thread is engaged, the leading screw slides up and down and drives bridge to lift, also
Including the lifting oil cylinder below worm gear case, the lifting oil cylinder includes the cylinder block provided with plunger shaft, the plunger shaft
Interior to be provided with piston, the piston is installed on piston rod, and the upper end of the piston rod is connected with leading screw.
Preferably, the plunger shaft includes the valve piston chamber of bottom and the big plunger shaft on top, the piston rod is big
Big piston is installed, the piston rod is provided with valve piston in valve piston chamber, and the diameter of the valve piston chamber is small in plunger shaft
It is provided with big plunger shaft diameter and valve piston chamber with big plunger shaft connecting part to determining that big piston lowermost position is positioned
Position step, the valve piston chamber is connected with fuel feed hole.
Preferably, being provided with the lower cover of mouth under closed piston chamber below the cylinder block, opened up on the lower lid
There is fuel feed hole, the fuel feed hole is connected with in-line, and the in-line enters in plunger shaft provided with control hydraulic oil
Magnetic valve.
Preferably, the leading screw and piston rod are structure as a whole.
Preferably, the top of the worm gear case, which is provided with to be provided with boring cover, the boring cover, prevents the same of leading screw rotation
When the feather key that slides up and down of guiding leading screw.
The technical solution adopted in the utility model, realizes that upper bridge is overall fast by the quick motion of piston in lifting oil cylinder
Fast lifting, compared with motor control more fast and stable, reaction is more rapid, and in lifting and resetting engineering, entirely upper bridge
Accurate adjustment can be carried out by the cooperation of worm and gear screw mandrel, Adjustment precision is high.
Brief description of the drawings
The utility model is further described with reference to the accompanying drawings and detailed description：
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in figure 1, bridge rapid uplift and resetting means on splitting machine, including the upper bridge 1 that is lifted along left and right guide plate and
It is fixed in the worm gear case 2 on the guide plate of left and right, the worm gear case and is provided with worm gear 21, worm screw and leading screw 20, the worm gear and worm screw
It is staggered and engages connection, the leading screw is passed through and mutually screw thread engagement from worm gear center vertical, and it is matched somebody with somebody by worm and gear
Driving leading screw 20 is closed to slide up and down and drive bridge 3 to lift.
Further, in order to realize the overall rapid uplift of upper bridge, lifting oil cylinder 1 is additionally provided with, the lifting oil cylinder includes
Piston is provided with cylinder block 10 provided with plunger shaft, the plunger shaft, the piston is installed on piston rod, the piston rod
Upper end stretch out and be connected with leading screw 20 from cylinder block.The preferred ball-screw of leading screw, piston rod and ball screw are preferably
Same part, so ensures that lifting oil cylinder in lifting and reset engineering, entirely upper bridge can pass through worm and gear
Ball screw is adjusted, and both are mutually independent of each other.
Wherein, plunger shaft includes the valve piston chamber of bottom and the big plunger shaft on top, and the top of cylinder block 10 is provided with upper
The closed piston chamber of lid 11 is suitable for reading, and the bottom of cylinder block, which is provided with mouth under the closed piston chamber of lower cover 14, lower lid, offers fuel feed hole.
The piston rod is provided with big piston 12 in big plunger shaft, and the piston rod is provided with valve piston 13, institute in valve piston chamber
The diameter for stating valve piston chamber is less than big plunger shaft diameter and valve piston chamber with big plunger shaft connecting part provided with most lower to big piston
Put the positioning step positioned in orientation.Fuel feed hole is connected with in-line, and in-line enters provided with control hydraulic oil lives
Fill in the magnetic valve in chamber.And the cavity between big piston 12 and valve piston 13 needs the stomata that begins to rehearse, confined air otherwise can be formed
Between.
Big plunger shaft oil-feed, the larger positioning being pressed in cylinder body 10 that can be by upper bridge 3 steadily of pressure when resetting
On step, it is fixed on equivalent to whole upper bridge on the guide plate of left and right.The main effect of valve piston 13 is bridge 3 in quick lifting.Lift
It is not same to rise piston used and push piston with reset use state, to reach small area piston rapid increase, large area
The stable upper bridge of piston.
During splitting machine normal work when needing up-regulation lifting, press after electric switch, liquid is controlled by hydraulic buttery valve
Force feed is entered in valve piston chamber by fuel feed hole on lower cover 14, because the oil chamber volume is smaller, as long as into relatively small oil just
Quickly upper bridge can be lifted, play a part of rapid uplift.And then reset upper bridge location to postpone, hydraulic oil enters big piston
Chamber, piston is tightly pressed on cylinder body 10, because big piston relative area is larger, and the pressure of formation is larger can will be upper
Bridge steadily push down fixed position, cut open layer and enter upper bridge during skin and can not be entered the power of skin formation to produce lifting displacement.
The top of the worm gear case is provided with square boring cover 22, the boring cover and is provided with feather key, can both prevent
Ball screw rotates, and can slide up and down again.
Bridge rapid uplift and resetting means are set simultaneously in the left and right sides of upper bridge on above-mentioned splitting machine, in addition, in liquid
Flow control element is also equipped with pressure pipe road and is risen and reset to ensure that left and right is synchronous.
