Description
Technical field
The utility model relates to a kind of SF6 combination valve calibration mechanisms.
Background technique
In mechanical processing process, it is often necessary to first fix workpiece by clamping device, obtain workpiece relative to machine
The correct position of bed and cutter, then workpiece is processed.Workpiece is fixed by clamping device, due to the position precision of workpiece
Guaranteed by clamping device, not will receive the influence of worker's technical level, so Workpiece Machining Accuracy is high and stablizes, and then reduced useless
Product rate ensure that the quality of product；Again since clamping device can make the rapid positioning and clamping of workpiece, significantly reduce auxiliary
Working hour improves production efficiency.It not only can guarantee mechanical processing quality in this way, and improved production efficiency, reduce labor intensity, but also can drop
The low excessive demand to worker's technology.But structure is complicated for universal clamping device, cumbersome, and maintenance maintenance is at high cost.It is real
Use new content
The utility model provides a kind of SF6 combination valve calibration mechanism, improves the fixed effect of two components, structure letter
Folk prescription just, does not need frequently to dismantle, more laborsaving.
To achieve the above object, the technical solution of the utility model is: a kind of SF6 combination valve calibration mechanism, comprising:
D connector with upper valve core assembly, the D connector are trapezium structure, and the bottom end of D connector has the protrusion extended downwardly
Portion；
C connector with lower valve core assembly has the card hole for the insertion of D connector boss on C connector；
Bolt hold-down mechanism is arranged on D connector, for after D connector insertion C connector by D connector tightly in C connector,
It include: pedestal, handle, positioning plate, bolt, the pedestal is bolted on D connector, which is contract type block,
The other end is the vertical plate with level-one positioning hole groove, and described handle one end is hinged on contract type block, the handle close to contract type block with
There is a torque arm at the position of pedestal connection, the bolt and torque arm are hinged, and the positioning plate is arranged side by side at vertical plate
Side, the positioning plate be equipped with the two-stage positioning hole slot big with level-one positioning hole groove notch etc..
The level-one positioning hole groove and two-stage positioning hole slot are arranged side by side.
The size of the level-one positioning hole groove notch is slightly larger than the width of handle.
The bolt hold-down mechanism quantity is two groups and the opposite two sides that D connector is arranged in.
The upper valve core assembly is arranged in the sealing surface of D connector, and the sealing surface of C connector is arranged in the lower valve core assembly
It is interior.
The utility model has the beneficial effects that making D connector and C connector are quickly fixed to lock by flexible handle, make in D connector
Upper valve core assembly and lower valve core assembly in C connector respectively upwards, move down, flow gas, the device structure is simple, laborsaving
And it is easily operated.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the SF6 combination valve calibration mechanism of the utility model.
Fig. 2 is the structural schematic diagram of the D connector of the utility model.
Specific embodiment
With reference to the accompanying drawing 1,2 and specific embodiment the utility model is described in further detail.
The utility model discloses a kind of SF6 combination valve calibration mechanisms, comprising:
D connector 6 with upper valve core assembly 61, the D connector 6 are trapezium structure, and the bottom end of D connector 6, which has, to be extended downwardly
Lug boss；
C connector 7 with lower valve core assembly has the card hole for the insertion of 6 lug boss of D connector on C connector 7；
Bolt hold-down mechanism 8 is arranged on D connector 6, connects for D connector 6 to be pressed on C after the insertion C connector 7 of D connector 6
On first 7 comprising: pedestal 1, handle 2, positioning plate 3, bolt 4, the pedestal 1 are bolted on D connector 6, the pedestal
1 one end is contract type block, and the other end is the vertical plate with level-one positioning hole groove, and described 2 one end of handle is hinged on contract type block, this
Hand 2 has a torque arm 21 at the position that contract type block is connect with pedestal 1, and the bolt 4 and torque arm 21 are hinged, described fixed
Position plate 3 is arranged side by side at the side of vertical plate, which is equipped with the two-stage positioning hole big with level-one positioning hole groove notch etc.
Slot, 8 quantity of bolt hold-down mechanism are two groups and the opposite two sides that D connector 6 is arranged in.
Wherein, level-one positioning hole groove and two-stage positioning hole slot are arranged side by side, and when being fixed and clamped, bolt 4 passes sequentially through level-one
Positioning hole groove, two-stage positioning hole slot position and accurately compress D connector 6.The size of level-one positioning hole groove notch is slightly larger than handle
The width of hand 2 facilitates handle 2 to be caught in or extract easily.
The upper valve core assembly 61 of the utility model is arranged in the sealing surface of D connector 6, and the lower valve core assembly is arranged in C
In the sealing surface of connector 7.
As shown in Fig. 2, height of upper valve core assembly 61 of the lug boss height H of D connector 6 greater than twice apart from lug boss end
A is spent, the reasons why end height on lower valve core assembly distance C connector 7 with extension is also A, which designs: making D connector 6
Lug boss be fully inserted into the card hole of C connector 7, the contact as big as possible with lower valve core assembly of upper valve core assembly 61 or separate.
Specific implementation process:
6 lug boss of D connector is fully inserted into the card hole of C connector 7, pulls two handles 2 counterclockwise, makes two bolts 4 simultaneously
Firmly by the trapezoidal halfpace locking positioning of D connector 6, upper valve core assembly 61 moves up in the sealing surface of D connector 6, bottom spool
Component moves down in the sealing surface of C connector 7, and two sealing surfaces are opened, airflow.Conversely, it is then clockwise to close sealing surface
Pull two handles 2.
In summary it is only the preferred embodiment of the utility model, not is used to limit the implementation model of the utility model
It encloses.Equivalent changes and modifications made by i.e. all contents according to present utility model application the scope of the patents, all should be the utility model
Technology scope.
