Abstract
The utility model discloses a pressure testing machine with hydraulic transmission to adjust testing space, including a lifting device and a pressure device. The lifting device is connected with the pressure device through a column, which is fastened through a nut. A top beam is arranged on the upper part of the column and a base is fixed at the bottom of the pressure device. The lifting device includes a lifting fuel tank with a lifting piston inside positioned on the top beam, the lifting fuel tank is fastened with a lifting cover through a screw and the lifting piston is fastened with an upper pressure plate through the screw. With the above structure, the utility model could make the piston do up-and-down movement with the oil supplying of hydraulic pump to adjust the distance between the upper pressure plate and a lower pressure plate and then adjusts the testing space of the pressure testing machine.
Description
Technical field
The utility model discloses and a kind ofly adjust the pressure test of test space, belong to the pressure testing machine technical field with hydrostatic transmission.
Background technology
Existing pressure testing machine mainly adopts mechanically operated mode to the adjustment of test space, and main employing is the large diameter acme thread kind of drive of coarse pitch, mainly comprise jacking gear, device for exerting, jacking gear is connected by column with device for exerting, and fastening by nut, also be provided with upper beam on the column, described jacking gear comprises the last swivel nut that is used with screw mandrel that install of putting the beams in place, the top board that the lower end of screw mandrel is provided with, described device for exerting comprises lower platen.When pressure testing machine carries out pressure test, to different test blocks, must move up and down or screw mandrel is moved up and down by the direct rotary screw of manual mode by the rotation that worm and gear drives swivel nut, adjust the distance between top board and the lower platen, after the locus was suitable, the rising by hydraulic piston compressed test block and exerts pressure again.This product is when making, and swivel nut cooperates the precision prescribed height with the acme thread of screw mandrel, otherwise causes displacement easily in process of the test, test power error is increased, even behind certain pressure, swivel nut and screw mandrel rotate dumb even stuck, cause and can't test.When if the rotation of adopting worm and gear to drive swivel nut moves up and down screw mandrel, worm and gear requires also than higher machining accuracy, and in the process of the test of being everlasting, influenced by certain pressure, make worm and gear owing to the reason of clearance fit causes and can't move, thereby abort has caused certain loss to company.
The utility model content
For addressing the above problem, it is a kind of by hydraulic transmission mode that the utility model purpose is to provide, and adjusts the pressure testing machine of the test space of pressure testing machine.
The technical scheme that its technical matters that will solve the utility model adopts is: a kind of pressure testing machine of adjusting test space with hydrostatic transmission, comprise jacking gear, device for exerting, jacking gear is connected by column with device for exerting, and it is fastening by nut, the top of column is provided with upper beam, the bottom of device for exerting is installed with base, it is characterized in that: described jacking gear comprises and places the hoist cylinder that is provided with lifting piston in put the beams in place going up, hoist cylinder is fastenedly connected by screw and hoist cylinder lid, and lifting piston is fastenedly connected by screw and top board.
Of the present utility modelly further be set to: described device for exerting also comprises the master cylinder that is provided with main piston in being installed on the base, is placed with lower platen on the master cylinder, and lower platen is connected with main piston by screw.
Of the present utility modelly further be set to: all be provided with O-ring seal on lifting piston, hoist cylinder lid, the master cylinder.
After adopting said structure, the utility model technological requirement is low, and the lifting stable drive easily is automated the control operation.Can pass through the hydraulic pump fuel feeding, lifting piston is moved up and down, adjust the distance between top board and the lower platen, reach the purpose that to adjust the pressure testing machine test space.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises jacking gear 1, device for exerting 2, column 3, nut 4, base 5.Jacking gear 1 is connected by column 3 with device for exerting 2, and it is fastening by nut 4, the top of column 3 is provided with puts the beams in place 11, described jacking gear 1 comprises and places the hoist cylinder 12 that is provided with lifting piston 13 in putting the beams in place on 11, hoist cylinder 12 and lifting piston 13 are for closely cooperating, hoist cylinder 12 is fastenedly connected by screw 16 and hoist cylinder lid 14, and lifting piston 13 is fastenedly connected by screw 103 and top board 15.2 of described device for exerting also comprise the master cylinder 22 that is provided with main piston 23 in being installed on the base 5, and master cylinder 22 and main piston 23 are placed with lower platen 24 for closely cooperating on the master cylinder 22, and lower platen 24 passes through screw 25 and closely is connected with main piston 23.Be respectively equipped with O-ring seal 17,18,26 on lifting piston 13, hoist cylinder lid 14, the master cylinder 22, make jacking gear 1, device for exerting 2 have better sealing property.
When the utility model carries out pressure test, the carrying that pressure oil entered when master cylinder 22 was detected pressures, the supporting body that main piston 23 is mainly exerted pressure to test block by lower platen 24 conducts, the lifting space requirement of this part does not greatly make different test blocks or test block of the same race can put into the test space of pressure testing machine and conveniently promptly test, just must adjust distance between top board 15 and the lower platen 24, reach the purpose that to adjust the pressure testing machine test space by lifting piston 13.Adjust the test space of pressure testing machine, need by the hydraulic pump fuel feeding, from hoist cylinder 12, advance face hydraulic fluid port 19 input hydraulic pressure oil, the hydraulic oil in zone 101 is then discharged from advance face hydraulic fluid port 102,13 of lifting pistons move downward, thereby top board 15 is also moved downward, thereby dwindle test space.Otherwise, from hoist cylinder 12, advance input hydraulic pressure oil in the face hydraulic fluid port 102, then lifting piston 13 moves upward, and top board 15 also moves upward, thereby increases test space.
