Description
Technical field
The present invention relates to a kind of hydraulic pressure testing device, especially a kind of hydraulic pressure testing device for round shape workpiece, belong to
Product pressure test test equipment technical field.
Background technology
Hydraulic pressure test is the whether intact necessary detection project of valve type part.In prior art, hydraulic pressure testing device one
As include pressing plate and tool base plate, tool base plate both sides are provided with bolt, pressing plate and tool base plate are bolted, right
When part carries out hydraulic pressure test, workpiece is clamped between pressing plate and tool base plate, then is led to water by the water pipe connecting on base plate
Enter inside workpiece；When carrying out hydraulic pressure test every time, it is required for dismounting once, testing efficiency is relatively low.In addition, hydraulic pressure common at present
Test device workpiece is typically all horizontal positioned pressing plate and tool base plate clamps workpiece from the upper and lower surface of workpiece, respectively in water
In pressure test process, workpiece one side will bear the hydraulic pressure of inside, still suffer from the pressure of workpiece surface, be easily caused test
Result inaccurate.
Content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, provides a kind of hydraulic pressure testing device, ensure that
Workpiece cavity sealing during hydraulic pressure test, reduce test device to the pressure influence of workpiece it is ensured that test result accurate.
The technical scheme providing according to the present invention, a kind of hydraulic pressure testing device, including bearing, it is characterized in that：At described
Workpiece fixing seat is installed in one end of seat, and the inner side of workpiece fixing seat is provided for placing the spacing backing plate of workpiece, workpiece fixing seat
Inner face contact with the end face of workpiece, on the outer face of workpiece fixing seat connect water inlet pipe；The other end in described bearing
Slide setting Mobile base, and Mobile base is connected with the clutch end of driving means；Compact heap, compression are installed on described Mobile base
Block is close-fitting sealing surface with workpiece towards the side of workpiece fixing seat；Setting and spacing backing plate below described compact heap
The positive stop matching.
Further, described workpiece fixing seat and Mobile base are horizontally set on the both sides of workpiece respectively.
Further, described bearing arranges slide rail, slide on slide rail setting slide block, slide block is fixed with Mobile base.
Further, described driving means include screw mandrel and the feed screw nut coordinating on screw mandrel by screw thread, screw mandrel spiral shell
Mother is fixedly connected with Mobile base, installs handwheel in the end of screw mandrel.
Hydraulic pressure testing device of the present invention ensure that workpiece cavity sealing during hydraulic pressure test, reduces test device
Pressure influence to workpiece it is ensured that test result accurate.
Brief description
Fig. 1 is the axonometric drawing of hydraulic pressure testing device of the present invention.
Fig. 2 is the front view of hydraulic pressure testing device of the present invention.
Fig. 3 is the top view of hydraulic pressure testing device of the present invention.
Specific embodiment
With reference to concrete accompanying drawing, the invention will be further described.
As shown in FIG. 1 to 3：Described hydraulic pressure testing device includes water inlet pipe 1, workpiece fixing seat 2, positive stop 3, handwheel
4th, bearing 5, workpiece 6, spacing backing plate 7, slide rail 8, slide block 9, Mobile base 10, feed screw nut 11, screw mandrel 12, compact heap 13 etc..
As shown in FIG. 1 to 3, hydraulic pressure testing device of the present invention, including bearing 5, installs workpiece in one end of bearing 5
Fixed seat 2, the inner side of workpiece fixing seat 2 is provided for placing spacing backing plate 7, the inner face of workpiece fixing seat 2 and the work of workpiece 6
The end face contact of part 6, the outer face of workpiece fixing seat 2 connects water inlet pipe 1；In the other end of described bearing 5, slide rail is set
8, slide on slide rail 8 setting slide block 9, and slide block 9 is fixing with Mobile base 10, the bottom connection wire rod nut 11 of Mobile base 10, silk
Stem nut 11 is threadedly attached on screw mandrel 12, and handwheel 4 is installed in the end of screw mandrel 12；Compression is installed on described Mobile base 10
Block 13, compact heap 13 is close-fitting sealing surface with workpiece 6 towards the side of workpiece fixing seat 2.
Pressure in order to prevent compact heap 13 and workpiece fixing seat 2 clamping workpiece 6 is too big, is mounted with the lower section of workpiece 6
Spacing backing plate 7, this spacing backing plate 7 is matched with the positive stop 3 of compact heap 13 lower section；When the side of spacing backing plate 7 and spacing
When the side of block 3 contacts, the die cavity of workpiece 6 is just sealed by compact heap 13 and workpiece fixing seat 2 from the both sides of workpiece 6,
To prevent compact heap 13 to be moved through position, unnecessary pressure is caused to workpiece 6.
The work process of the present invention：Workpiece is placed on spacing backing plate 7, by shaking handwheel 4, by Mobile base 10 to work
Part 6 one side shifting, until spacing backing plate 7 and positive stop 3 contact and limit the further workpiece pressing 6 of Mobile base 10；Now,
The die cavity of workpiece 6 is realized sealing by the workpiece fixing seat 2 of both sides and compact heap 13.Noted in the die cavity of workpiece 6 by water inlet pipe 1
Enter water, do not pressed test.
The present invention can avoid test device that the thrust of workpiece 6 is transshipped, and prevents the pressure influence hydraulic pressure test transshipping
Result.
