It ships and resell on another market.
Preferably, the bolt extends drive end bearing bracket, between the drive end bearing bracket and fulcrum bearing, rear end cap and branch
It holds and is bolted between seat respectively.
Preferably, the left side oil circuit, right side oil circuit extend upwardly to operation cavity from the bottom of fulcrum bearing respectively
In.
Preferably, the bottom end of the fulcrum bearing is equipped with several bolts hole, the bottom of the bolt hole and fulcrum bearing
Bottom.
By hydraulic transmission in conjunction with worm drive, not merely with worm drive the characteristics of, reached the requirement of high supporting force,
The combination of hydraulic transmission and worm drive simultaneously, reduces the volume of oil pressure clamping cylinder entirety.This rotary bearing support cylinder invention is special
Benefit solves the problems, such as that high bearing power cylinder is difficult to install and use in small space, provides one kind for the design of hydraulically operated fixture
New design scheme.
Solve traditional beveling block formula oil hydraulic cylinder, the shorter problem of stroke.
The characteristics of using threads turn, supporting device is made to have self-locking function, solves traditional oil cylinder without self-locking function
The problem of.
There is oil circuit in fulcrum bearing cavity, left side oil circuit oil inlet, when right side oil circuit is fuel-displaced, in the case where the flowing of oil drives, and
Under the action of fulcrum bearing cavity, rotor, the volume change in the confined space that is formed between blade, rotor generates rotation.Equally,
Right side oil circuit oil inlet, when left side oil circuit is fuel-displaced, the rotation of opposite direction occurs for rotor.
Transmission is connected through a screw thread between rotor inner hole internal screw thread and bolt external screw thread.Stop pin is oriented to guide rod part
Prevent bolt from rotating with bolt regular hexagon inner hole for hexagon.As a result, rotor occur it is positive or
When rotating backward, by the threaded connection between bolt, the straight line for being converted into bolt is pushed forward or retraction
Movement.
Using formula bearing support cylinder is rotated above, the control acted to bolt, realization pair can be realized by controlling oil circuit
The clamping of workpiece and loosen.
Therefore, the rotary bearing support cylinder of hydraulically operated fixture that caliper class part is processed in the automotive brake of the utility model, knot
Structure is simple, easy to operate, promotes its service performance.
