Description

A kind of inspection tooling for the disk miller hydraulic test that more is open
Technical field
It is specifically a kind of for the dish-type that more is open the present invention relates to a kind of verifying attachment for machinery industry hydraulic test The inspection tooling of part hydraulic test.
Background technology
The metal disk miller that machinery industry uses, rear and front end sealing structure generally use radial seal or end face seal knot Structure is connected using ring flange connection or key ring.For being open in structure, more, bearing capacity is high, there is the product at non-bearing position, Hydraulic test and sealing are difficult solution, while can not completely isolated non-bearing position.
It is found by retrieving patent document and paper database both domestic and external, " a kind of upper and lower flange face of cavity hatch is uneven Capable casting pressure-detecting device " (publication number:CN105181277A it) uses and is resisted against casting cavity open lower end flange face Profile-followed pulling plate, the pressing plate being resisted against in cavity hatch upper flange surface, rubber pad, by passing through the last one between profile-followed pulling plate and pressing plate Tie-rod connection is drawn in order to be secured against, is mainly used for not parallel, the simple in structure casting of flange face that is open, for opening more Mouth part can not complete pressure test, while the non-bearing position of part can not be isolated;A kind of " big nozzle detachable hydraulic Sealing device " (publication number:CN102374290A) by one section of cylinder be placed in needed for seal take in, and set in the side of cylinder The inner wall that cylinder is mounted on take over pressure vessel by support device is set, setting is adjusted it and installs elastic journey in the other side of cylinder Degree, while adjusting the sealing device of its seal degree and cylinder is sealed interface with taking over, it is mainly used for simple cylinder Sealing test, hydraulic test can not also be carried out for the class disk miller that more is open, while non-bearing position can not be isolated.
Invention content
To overcome more opening class disk miller existing in the prior art that can not carry out hydraulic test, and can not be to non-bearing The deficiency that position is isolated, the present invention propose a kind of inspection tooling for the disk miller hydraulic test that more is open.
The present invention includes upper blanking cover, opening blanking cover, cylinder blanking cover, pedestal, water supply connector and pressure tap plug.It is therein to open Mouth blanking cover is absolute construction, is used cooperatively with the upper blanking cover and cylinder blanking cover, realizes the sealing to the disk miller that more is open.
The cylinder blanking cover is located in the pedestal, and is fixedly mounted on the center of the plate upper surface of the pedestal.It is upper stifled Lid is fixed on the upper surface of the pedestal.The water supply connector is fixed on the center of the upper blanking cover upper surface, and with positioned at this The inlet opening at upper blanking cover center is connected.There is pressure tap on the upper blanking cover, pressure tap plug is installed on the pressure tap.
The opening blanking cover directly coordinates with more opening disk millers.
There is axial annular convex platform in the following face of upper blanking cover edge, and upper blanking cover is equipped in the lower face of the annular convex platform Upper blanking cover sealing ring.It is useful for the connecting flange of connect base in the external peripheral surface of the upper blanking cover.In the upper blanking cover The heart has inlet opening;In the inlet opening, there is pressure tap in side.
The edge of cylinder blanking cover lower surface is ladder-like, forms the positioning of the cylinder blanking cover and more opening disk miller cooperations Seam allowance.It is fixed with connecting rod at the center of cylinder blanking cover lower surface.It is embedded on the cascaded surface of cylinder blanking cover lower surface There is cylinder blanking cover cylinder blanking cover sealing ring.
The center of pedestal lower end bottom plate is equipped with connecting rod.The center of the pedestal upper end end face is round hole, the trepanning Aperture slightly larger than opening blanking cover and the maximum outside diameter after more opening disk millers cooperations.The upper surface of pedestal upper surface outer rim There is axially projecting connecting seat, which is evenly distributed in the upper surface the connecting hole for being useful for connecting the upper blanking cover;Pass through multiple spiral shells Pedestal and upper blanking cover are connected by bolt.
The end face of the step difference of the external peripheral surface of opening blanking cover forms and the positioning surface after mostly opening disk miller cooperation. There is the seal groove of construction opening blanking cover sealing ring in the circumferential surface of the opening blanking cover.There is axis at the opening blanking cover lower surface center To threaded rod, cushion block is sleeved on the threaded rod and fastened by nut, and by adjusting the position of the cushion block, realizes split Mouth blanking cover limit.
The present invention is suitable for more opening disk millers of the diameter no more than 500mm and detects disk miller thickness in 5~20MPa pressure Flange arrangement tests outer circle lateral openings slot and the sealing station of the small trepanning of flange face, while ensureing thin-walled cylinder section hydraulic pressure mistake Pressure is not subject in journey.
The present invention is and real by the opening connection sealing each to the disk miller that more is open respectively of the upper blanking covers of 3 different structures It now limits, fasten, it is easy to assembly, sealing structure form is detached using to the disk miller that more is open, realizes the disk miller thin-walleds that are open more Cylindrical section is isolated with flange end, ensures that more opening disk miller cylindrical sections are not subject to pressure, prevent cylindrical section from deforming.
Compared with prior art, beneficial effects of the present invention are:
Tooling is examined to realize that complicated more opening disk miller hydraulic pressure are surveyed by upper blanking cover, opening blanking cover, cylinder blanking cover Examination, it is simple in structure, it is easy to operate.
Inspection man, according to more opening disk miller own structural characteristics, realizes corresponding blanking cover limit mounted in each opening sealing station Position ensures assembly zero defect.
It examines tooling to use and sealing structure form is detached to the disk miller that more is open, realize the disk miller thin-walled cylinder sections that are open more It is isolated with flange end, ensures that more opening disk miller thin-walled cylinder sections are not subject to pressure, prevent from deforming.
