Abstract
A kind of double hydraulic cylinder sync control device, it is included by two identical hydraulic cylinder assemblies, and sliding block beam, the piston rod of two hydraulic cylinder assemblies is symmetrically fixed on above the both ends of sliding block beam, a screw thread of the large pitch without self-locking is fixedly mounted at the piston centre position of each hydraulic cylinder assembly, leading screw is installed together with feed screw nut in a manner of screw thread coordinates, the outside of cylinder body is stretched out in the upper end of leading screw, and the top with cylinder body by bearing rotary, first bevel gear is fixedly mounted in leading screw end outside each stretching cylinder body, each first bevel gear and second bevel gear are intermeshed, two the second bevel gears are fixed on the both ends of power transmission shaft, the utility model has synchronous reliable, the higher place of synchronous requirement is can adapt to use.
Description
Technical field
It the utility model is related to hydraulic press, and in particular to portal-type hydraulic machine double hydraulic cylinder sync control device, belong to liquid
Technical field of pressing machine.
Background technology
It is well known that the typically up and down motion with longer sliding block beam, sliding block beam of portal-type hydraulic machine is by setting
Two Driven by Hydraulic Cylinder installed in sliding block beam both ends, in the course of work of the higher portal shaped hydraulic press of some requirements
Sliding block beam is asked to keep balance, the hydraulic cylinder synchronous control of existing portal shaped hydraulic press, usually using liquid during motion
Pressure system is realized, HYDRAULIC CONTROL SYSTEM hydraulic cylinder, realizes that double hydraulic cylinder balances, although this mode have it is simple in construction,
Installation manufacture it is more convenient the advantages of, still, hydraulic system is easily influenceed by extraneous factor, exist reliability it is poor lack
Fall into.
Utility model content
The purpose of this utility model is：A kind of new double hydraulic cylinder sync control device is provided, this kind of device has
The advantages of synchronization accuracy is higher, disclosure satisfy that some site requirements hydraulic cylinder synchronous required precision high fields use.
Technical scheme is used by the utility model realizes above-mentioned purpose：A kind of described double hydraulic cylinder Synchronization Control dress
Put, it is included by two identical hydraulic cylinder assemblies, and sliding block beam（12）, described hydraulic cylinder assembly includes piston rod
（1）, cylinder body（2）, piston（3）, the piston rod of two hydraulic cylinder assemblies（1）Symmetrically it is fixed on sliding block beam（12）Both ends above,
In the piston of each hydraulic cylinder assembly（3）A feed screw nut is fixedly mounted in centre（4）, described feed screw nut（4）
Internal thread be screw thread of the large pitch without self-locking, in each feed screw nut（4）The piston rod of position directly below（1）On be formed with it is blind
Hole（13）, leading screw（5）With feed screw nut（4）It is installed together in a manner of screw thread coordinates, in feed screw nut（4）End portion
Leading screw（5）In blind hole（13）It is interior, blind hole（13）Diameter be more than leading screw（5）External diameter, leading screw（5）Upper end stretch out cylinder body
（2）Outside, and pass through bearing（6）Rotatably with cylinder body（2）Top be installed together, bearing gland（7）Center borehole jack
It is connected on stretching cylinder body（2）Outside leading screw（5）On, blending bolt and cylinder body（2）Top be fixed together, bearing gland（7）
Simultaneously by bearing（6）From axial restraint, in bearing gland（7）With leading screw（5）Between be provided with sealing ring（8）, stretched at each
Go out cylinder body（2）Outside leading screw（5）First bevel gear is fixedly mounted in end（9）, each first bevel gear（9）With one
Second bevel gear（10）Intermeshing, two the second bevel gears（10）It is fixed on power transmission shaft（11）Both ends.
Beneficial effect：Synchronization principles of the present utility model be it is such, the pistons of two hydraulic cylinder assemblies rise or under
During drop, due to feed screw nut（4）The leading screw to be cooperated with it（5）Between, be no self-locking large pitch screw thread, and
Leading screw（5）The free degree only rotated, so, work as piston（3）Drive feed screw nut（4）During being moved upwardly or downwardly, silk
Thick stick（5）With regard to forward or reverse, due to two leading screws（5）Between transmission be to pass through power transmission shaft（11）Rigidly it is connected, so,
It is also synchronous that the piston rod of two hydraulic cylinder assemblies, which moves up and down, it is clear that sliding block beam（12）Up and down motion be also to maintain it is flat
Weighing apparatus, it can be seen that by operation principle of the present utility model：The utility model have it is synchronous reliable, can adapt to it is synchronous require compared with
High place uses.
Brief description of the drawings
Accompanying drawing 1 is structure principle chart of the present utility model.
Shown in figure：1 it is piston rod, 2 be cylinder body, 3 be piston, 5 be leading screw, 6 be bearing, 7 be bearing gland, 8 is close
