Description
Technical field
The present invention relates to a kind of bearing support cylinder more particularly to a kind of hydraulic pressure processed for caliper class part in automotive brake
The rotary bearing support cylinder of fixture.
Background technology
In the hydraulically operated fixture that existing caliper machine adds, mostly directly workpiece is supported by hydraulic cylinder, needs larger branch
When load, used hydraulic cylinder cylinder diameter is also relatively large, and fixture overall volume is bigger than normal, it is difficult to the smaller, quality suitable for space
It is required that lighter operating mode.
Traditional beveling block formula oil hydraulic cylinder, stroke is shorter, and when needing long stroke, oil hydraulic cylinder volume needs equal proportion to increase.
Traditional oil cylinder after losing oil pressure, also can lose supporting force simultaneously, without self-locking function, there is nothing after losing oil pressure
The risk of method bearing.
Chinese patent 201080032969.7, it is open a kind of for generating hydraulic pressure due to tensile load or pressure load
Pressure generator, the Pressure generator carry connector, one of connector can with for transmit machinery pulling force
The mechanism of load or pressure load connects, and another connector can rigidly be connect with holder, pressure cylinder and piston unit, the work
Plug unit extends in the pressure cylinder at least partly and movably, and the restriction hydraulic pressure together with the pressure cylinder
The boundary of the hydraulic cavities of fluid filling, the connector are connect by coupling device with the pressure cylinder or the piston unit,
Wherein, the coupling device constructs in this way so that tensile load and under pressure load with the same hydraulic cavities of pressure-loaded.This
Structure is relative complex, and performance is relatively low.
Invention content
The present invention mainly solves the deficiencies in the prior art, provides a kind of compact-sized, small volume, supporting force
Larger, stroke is longer, band self-locking, realizes that the caliper class part in automotive brake that is used for of high-clamping force purpose in small space is processed
The rotary bearing support cylinder of hydraulically operated fixture.
The above-mentioned technical problem of the present invention is mainly to be addressed by following technical proposals：
A kind of rotary bearing support cylinder of hydraulically operated fixture processed for caliper class part in automotive brake, including fulcrum bearing, it is described
Fulcrum bearing in be equipped with operation cavity, rotor is equipped in the operation cavity, be equipped in being set in the rotor along rotor into
Fulcrum bearing is extended in one end of the bolt of row rotation displacement, the bolt, is equipped with and behaviour in the fulcrum bearing
The left side oil circuit being connected as cavity is equipped with the right side oil circuit being connected with operation cavity, left side oil circuit in the fulcrum bearing
Oil inlet drive rotor rotates and bolt is driven to carry out rotating in the forward direction displacement, the rotation of right side oil circuit oil inlet drive rotor along rotor
And bolt is driven to carry out reverse rotation displacement along rotor.
Preferably, the edge of the rotor is equipped with the blade of 4 half built-ins, the edge of the blade and operation
Cavity mutually touches.
Preferably, the front end of the fulcrum bearing is equipped with the drive end bearing bracket mutually positioned with bolt, the fulcrum bearing
Rear end be equipped with the rear end cap that is mutually positioned with bolt, be equipped in the rear end cap and plug the anti-of locking with bolt
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 is bolted respectively between bearing.
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.
Hydraulic transmission is combined 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
Profit solves the problems, such as that high bearing power cylinder is difficult to install and use in small space, and one kind is provided 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 the volume change in confined space formed between fulcrum bearing cavity, rotor, 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 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 processed for caliper class part in automotive brake of the invention, knot
Structure is simple, easy to operate, promotes its performance.
