Description
Technical field
The present invention relates to a kind of tooling, specifically a kind of anti-pressure type hydraulic pressure test fixture of pump case.
Background technique
For pump case class product in batch production, product must do hydraulic pressure test on hydrostatic testing machine.Hydrostatic testing machine is adopted
With the sealing means for compression of taking blame for others, and the pressure of taking blame for others of equipment be it is directly proportional with the sealing bore of product, i.e., bore is taken blame for others more greatly
Pressure is bigger, this will make deformation of products because of excessive pressure of taking blame for others, or even flatten, and leads to scrap of the product.
Summary of the invention
For the defect of above equipment technique, the present invention provides a kind of convenience, reliable Fixture Design, and product is avoided to exist
Because equipment pressure of taking blame for others is non-adjustable when doing hydraulic pressure test, bring quality risk.
To achieve the above object, the invention provides the following technical scheme:
A kind of anti-pressure type hydraulic pressure test fixture of pump case, including input end flange seal cover board, support column against pressure, connecting pin are close
Plate and outlet end flange seal cover board are covered, the input end of measured workpiece is fixed on input end flange seal by four screws one
On cover board, using axial seal, four screws one are fixed by nut one, and the input end of measured workpiece passes through four screws
One is fixed on input end flange seal cover board, and using axial seal, four screws two are fixed by nut two, it is described go out
The center of mouth end flanges seal cover board opens up water injection hole, and water injection hole is used as pressurization hole simultaneously；
The connecting pin for connecting end seal plate and measured workpiece is positioned by the clearance fit of hole axle, through taking blame for others for pressure testing machine
It compresses, using radial seal, the center of the connecting pin seal cover board opens up gas vent, the lower section of the connecting pin seal cover board
Equipped with support column against pressure, the support column against pressure is fixed in the inner cavity of measured workpiece, and support column against pressure is to be greater than row by one section
The bar machine-shaping of air vent aperture, and both ends end face is provided with gutter channel, one end connects gas vent, and one end connects water injection hole.
Preferably, plain washer is equipped between the nut one and outlet end flange seal cover board.
Preferably, spring washer is equipped between the nut one and input end flange seal cover board.
Compared with prior art, the beneficial effects of the present invention are:
The present invention compresses pump case connecting pin seal cover board by taking blame for others, because of the work of radial seal and inner cavity support column against pressure
With product does not stress, and the power for generation of taking blame for others all conducts the use suitable for mass production in tooling by support column against pressure, effectively
It avoids causing deformation of products to be scrapped because taking blame for others pressure, improves Qualified Products Rate.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, a kind of anti-pressure type hydraulic pressure test fixture of pump case, including import end flanges are close in the embodiment of the present invention
Cover plate 1, screw 1, spring washer 3, nut 1, support column against pressure 5, connecting pin seal cover board 6, outlet end flange sealing
The input end of cover board 11, measured workpiece is fixed on input end flange seal cover board 1 by four screws 1, using axial close
Envelope, four screws 1 are fixed by nut 1, it is preferable that between the nut 1 and input end flange seal cover board 1
Equipped with spring washer 3, the outlet end of measured workpiece is fixed on outlet end flange seal cover board 11 by four screws 2 10, is adopted
With axial seal, four screws 2 10 are fixed by nut 28, it is preferable that the nut 1 is sealed with outlet end flange
Plain washer 9 is equipped between cover board 1, the center of the outlet end flange seal cover board opens up water injection hole 12, and water injection hole 12 is made simultaneously
It is used for pressurization hole；
The connecting pin for connecting end seal plate 6 and measured workpiece is positioned by the clearance fit of hole axle, the top through pressure testing machine
Cylinder compresses, and using radial seal, the both ends of the connecting pin seal cover board 6 open up card slot, in the connecting pin seal cover board 6
The heart opens up gas vent 61, and the lower section of the connecting pin seal cover board 6 is equipped with support column 5 against pressure, and the support column 5 against pressure is fixed on
In the inner cavity of measured workpiece, support column 5 against pressure is the bar machine-shaping for being greater than gas vent aperture by one section, and both ends end face is opened
There is gutter channel, one end connects gas vent 61, and one end connects water injection hole 12.
Working principle: measured workpiece such as Fig. 1 assembly is put into water pressure test machine worktable, taking blame for others, it is close to compress pump case connecting pin
Plate 6 is covered, because of the effect of radial seal and inner cavity support column 5 against pressure, product does not stress, and the power for generation of taking blame for others is all by against pressure
Support column 5 conducts in tooling.At this point, starting hydraulic pressure test process: water filling (being vented simultaneously), pressurization, pressure maintaining, pressure release, draining,
Hydraulic pressure test terminates.
