Referring to Fig. 1-Fig. 5, a kind of tight device of quick connection lock, including valve counter flange component, hopper counter flange group
Part, casing assembly, gas circuit control；The tight device of quick connection lock is circular configuration.
The valve counter flange component includes valve counter flange, imitative external screw thread tooth section, air cylinder fixed plate, cylinder, preceding
Duan Huan.Imitative external screw thread tooth section is evenly arranged on valve counter flange side, fixed during connecting locking and on the inside of shell to imitate
Internal screw thread tooth section matches.Cylinder fixing piece is arranged symmetrically in valve counter flange side, for fixing cylinder, while in cylinder
In telescopic process, wobbling action can be completed, so that shell be driven to rotate.
The hopper counter flange component includes hopper counter flange and O-ring seal, and hopper counter flange uses
Taper, the cone match with valve counter flange realize positioning and guiding.It is provided with dove-tail form seal groove in bottom surface simultaneously, is used
In installation sealing ring.
The casing assembly includes support ball bearing, butterfly spring, imitative internal screw thread tooth section and shell.Support ball bearing peace
Cased portion, in assembly, main support shell rubs sliding above hopper counter flange, while in shell rotation
Wiping is converted into rolling friction, to reduce frictional force.Imitative internal screw thread tooth section uniformly installs side inside the housing, locks in connection
During cooperate with the imitative external screw thread tooth section that is mounted on valve counter flange.Shell be mainly used to install imitative thread section and
Ball bearing is supported, while entire attachment device being protected not have the ground that drug falls to internal more difficult cleaning during disengagement
Side.
Imitative internal screw thread tooth Duan Yufang external screw thread tooth section in the case where cooperation, can be realized the locking of whole device.
Cylinder drives shell rotation, can realize imitative internal screw thread tooth Duan Yufang external screw thread tooth section and cooperate.
The cone match of hopper counter flange and valve counter flange, during assembly, even if in hopper transition
Flange and valve counter flange cannot achieve it is entirely on the center in the case where, can also complete guiding realize positioning.
It installs support ball additional, sliding friction is converted into rolling friction, reduces frictional force, it is whole to reduce to reduce cylinder dimensions
Body size.
Cylinder drives shell to rotate 20-22 degree, can realize imitative internal screw thread tooth Duan Yufang external screw thread tooth section and cooperate.
Imitative internal screw thread tooth Duan Yufang external screw thread tooth section in the case where cooperation, can be realized the locking of whole device.
The cone match of hopper counter flange and valve counter flange, during assembly, even if in hopper transition
Flange and valve counter flange cannot achieve it is entirely on the center in the case where, can also complete guiding and realize positioning, lower flange in realization
Automatic centering, to guarantee the rapid abutting joint function in hoisting process.
It installs support ball additional, sliding friction is converted into rolling friction, reduces frictional force, reduce cylinder dimensions and whole ruler
It is very little.
The tight device of this embodiment quick connection lock is by valve counter flange component, hopper counter flange component, shell group
The cylinder composition of part, CDM2E32-100Z-M9B, acts between valve and hopper, realizes that the connection of valve and hopper is locked,
And realize quick disassembling function.The valve counter flange component includes valve counter flange 19, imitative external screw thread tooth section 11, cylinder
Fixed plate 7, cylinder 2, front end ring 9 form.Before work, valve counter flange component passes through the bolt of 8 M18 × 18 with valve 1
It is fixed together, junction is sealed using the O-ring of model Φ 250 × 7.Hopper counter flange component is by hopper transition
Flange 18 and model are respectively the O-ring seal composition of Φ 295 × 7 and Φ 236 × 7.Casing assembly includes eight support balls
Bearing 15,14, six sections of butterfly spring imitative internal screw thread tooth sections 10 and shell 8.Before work, 5 lower end of hopper and casing assembly, annular
Pressing plate 4 and hopper counter flange component are fixed together by 8 bolts of M18 × 18, and hopper is connect with hopper counter flange
Place is sealed using the O-ring of model Φ 250 × 7.Hopper upper end is connect with lid 6, and junction uses model Φ 190
× 5.3 O-ring is sealed.
In the course of work, valve portion and hopper section are docked first.In docking operation, since crane is deposited
In position error, may result in two parts up and down cannot achieve complete coaxial line, at this moment can pass through 19 He of valve counter flange
Cone match between hopper counter flange 18 is oriented to as assembly and realizes rapid abutting joint.Institute's band pin shaft on shell 8 is inserted into
In front end ring 9, docking is completed.Then, cylinder is shunk, and drives shell 8 to rotate clockwise 20-22 degree by front end ring 9, in shell
Six sections of fixed imitative external screw thread tooth sections 11 of side, the six section imitative internal screw thread tooth sections 10 fixed with 19 side of valve counter flange cooperate, real
Now lock.After locking, inside forms closed cavity, can be realized at this time to the internal work that vacuumizes, and guarantee to reach sealing
Effect.When needing device to unclamp, after discharging inner vacuum to atmospheric pressure, stretched out by solenoid valve control cylinder, front end ring 9
The rotation 20-22 degree counterclockwise of shell 8 is driven, at this time six sections fixed on the inside of shell imitative external screw thread tooth sections 11 and valve counter flange
Position is staggered between six sections of fixed imitative internal screw thread tooth sections 10 of 19 sides, that is, completes to unclamp.
Casing assembly can effectively prevent impurity to fall into in-house in the mechanism course of work, and mechanism is caused to damage or pacify
Full accident.Eight support ball bearings 15 in casing assembly are supported between shell 8 and hopper counter flange 18, and reduction rotates through
Frictional force in journey extends the service life of device.Butterfly spring 14 is mounted between support ball bearing 15 and shell 8.It is locking
Under tight state, butterfly spring is generated elastic force by compression, thus increase imitative external screw thread tooth section 11 and imitative internal screw thread tooth section 10 it
Between coupling mechanism force, while the deformation that can pass through butterfly spring adjusts matching between imitative external screw thread tooth section 11 and imitative internal screw thread tooth section 10
It closes, prevents stuck, raising production efficiency.It is close that seal groove on hopper counter flange for mounting O-shaped rings should be dove-tail form
Sealing groove, such seal groove structure can reach the purpose that sealing ring is not fallen out in the case that sealing surface disengages, worked to prevent
O-ring generation gap is bitten or is squeezed out and leads to seal failure in journey, and for cooperation other sizes and avoids due to angle
It is too small and O-ring occur and pressed from both sides after compaction extremely spring back and the case where can not completely take out, the choosing of dovetail groove groove angle.
The operating process of this example
Step 1: operator completes connection, valve and the valve mistake of hopper and casing assembly and hopper counter flange
Cross the connection of flange assembly.
Step 2: operator connects cylinder gas circuit and control circuit, expanding-contracting action is completed for controlling cylinder.
Step 3: operator lifts the connector of hopper and casing assembly and hopper counter flange to valve transition
Above flange, package unit is made to be in the preparation state of docking.
Step 4: by institute's band pin shaft insertion cylinder front end ring, docking is completed on shell.
It is shunk Step 5: controlling cylinder by cylinder solenoid valve, shell rotation is driven to complete locking.
Step 6: controlling cylinder after device completes work by cylinder solenoid valve and stretching out, shell rotation is pushed, is completed
It unclamps, state is identical as step 4 state at this time, can be by the company of hopper and casing assembly and hopper counter flange after release
Fitting hangs valve counter flange, completes to disengage.
