Abstract
A water pressure test machine comprises a rectangular frame-shaped gantry and a platform fixed at the upper side of the lower crossbeam middle part of the gantry, wherein, a jack is fixed at the lower side of the upper crossbeam middle part of the gantry, an electromotor of the jack is fixed at the upper side of the upper crossbeam of the gantry, a piston rod of the jack is downward, a press plate is fixed at the lower end of the piston rod of the jack, the lower side surface of the press plate is opposite to the platform, a position sensor is fixed at the external side of an oil cylinder of the jack, the position sensor is connected with the controller of the electromotor. The water pressure test machine of the utility model uses the electromotor to drive and adopts the automation control, the labor strength is low, and the labor efficiency is high.
Description
Technical field
The utility model relates to a kind of testing equipment, particularly a kind of hydrostatic testing machine.
Background technology
The producer that produces explosion-proof electrification all must carry out the hydraulic testing of 1MPa to flameproof enclosure, present hydrostatic testing machine is made up of platform, portal frame, swivel nut, screw rod, water pump, flameproof enclosure is placed on the platform, artificial rotary screw, to rotatablely move converts rectilinear motion to, and shell is pressed on the platform, uses water pump that the flame proof cavity is injected water, produce hydraulic pressure and make it reach regulation numerical value, be used to check the weld seam and the intensity of flameproof enclosure.Its defective is: use the manually-operated screw rod, labour intensity is big, and efficiency is low, and the insecure of pressure also leaks sometimes.
The utility model content
For addressing the above problem, the utility model provides a kind of labour intensity low, the hydrostatic testing machine that efficiency is high.
The utility model hydrostatic testing machine, comprise rectangular box-like portal frame and the platform that is fixed on described portal frame sill middle part upside, wherein: the entablature middle part downside of described portal frame is fixed with lifting jack, the motor of described lifting jack is fixed on the entablature upside of described portal frame, the piston rod of described lifting jack is downward, the lower end of the piston rod of described lifting jack is fixed with pressing plate, and the downside of described pressing plate is relative with described platform.
The utility model hydrostatic testing machine, wherein: the oil cylinder outside of described lifting jack is fixed with position transducer, and described position transducer links to each other with the control device of described motor.
The utility model hydrostatic testing machine uses direct motor drive, adopts robotization control, and labour intensity is low, the efficiency height.
Description of drawings
Fig. 1 is the front view of the utility model hydrostatic testing machine.
Embodiment
Below in conjunction with Figure of description the utility model hydrostatic testing machine is described further.
Referring to Fig. 1, the utility model hydrostatic testing machine, comprise rectangular box-like portal frame 2 and the platform 5 that is fixed on portal frame 2 sills middle part upside, the entablature middle part downside of portal frame 2 is fixed with lifting jack 3, the motor 1 of lifting jack 3 is fixed on the entablature upside of portal frame 2, the piston rod of lifting jack 3 is downward, and the lower end of the piston rod of lifting jack 3 is fixed with pressing plate 4, and the downside of pressing plate 4 is relative with platform 5.
The oil cylinder outside of lifting jack 3 is fixed with position transducer 6, and position transducer 6 links to each other with the control device of motor 1.When being contacted by pressing plate 4, position transducer 6 can send stop signal to motor 1.
The utility model hydrostatic testing machine is placed on workpiece on the platform 5 in use, starts motor 1, and motor 1 rotation drives lifting jack 3, and will be rotatablely moved by lifting jack 3 converts rectilinear motion to, and at this moment pressing plate 4 presses down, with Work-sheet pressing, and the pressure of fetching water.After test is finished, open motor 1, pressing plate 4 rises, when arriving upper limit position, and trigger position sensor 6, motor 1 stops automatically.
The utility model hydrostatic testing machine changes former swivel nut and screw mechanism into lifting jack and motor, when converting rectilinear motion to rotatablely moving, use motor to realize, upper limit position at the piston rod of lifting jack 3 adds a position transducer 6, realizes this process automation control of workpiece pressing backhaul.The utility model hydrostatic testing machine adopts robotization control, raises labour efficiency, and reduces labor intensity, and the more firm of pressure can not leak.
Above embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineering technical personnel in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
