Description
Technical Field
The utility model relates to the field of pressure testing equipment, in particular to an electro-hydraulic pressure testing machine.
Background
Electrohydraulic pressure testers are used primarily for compression testing of various materials, for example: the compressive strength tests of cement, concrete, various building bricks, rubber pads, concrete members, metal members and the like. The machine applies test force by adopting a hydraulic system, test data is measured by an oil pressure sensor, and a nixie tube displays the test data, so that the machine has the functions of peak value holding, loading speed display and the like.
The existing electrohydraulic type pressure testing machine comprises a frame, wherein a loading plate is arranged in the frame, a lower pressing plate is arranged right above the loading plate, the lower pressing plate is connected with a screw rod, and the screw rod penetrates through the frame and is in threaded connection with the frame.
But the electro-hydraulic formula compression testing machine of this kind of structure makes the holding down plate go up and down through rotating the screw rod when using, because the screw rod is great and the position is higher for it is comparatively hard to rotate, and can't the visual observation the shift position of holding down plate.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an electro-hydraulic pressure testing machine to solve the problem of labor waste in use in the prior art.
In this scheme, an electrohydraulic formula compression testing machine, including frame and drive assembly, fixedly connected with carries thing board in the frame, drive assembly includes screw rod and turbine, the turbine rotates the top of connecting in the frame, the screw rod runs through the top of turbine and frame, and screw rod and turbine threaded connection, the vertical sliding connection of screw rod and frame, the one end fixedly connected with holding down plate that the screw rod is located the frame, and the turbine meshing has the worm, and the worm rotates with the frame to be connected.
The working principle and the beneficial effects of the scheme are as follows: during the use, drive the turbine through corotation worm and rotate, because screw rod and turbine meshing, the screw rod is simultaneously again with the vertical sliding connection of frame, therefore the turbine rotates the screw rod and can be driven the decline, and the screw rod vertical removal can drive the holding down plate decline, and the reversal turbine can drive the holding down plate and rise. Adopt simple structure in this scheme, changed the direction of drive assembly for current direction of drive is with original perpendicular, and is more convenient during the drive, plays the effect of sparingly strength, and when the holding down plate, can be when rotating the worm, sees the position that the holding down plate removed directly perceived, is convenient for control the holding down plate and awaits measuring the distance between the work piece.
Further, the side of screw rod is equipped with vertical spout, the top of frame is equipped with the mounting hole coaxial with the turbine, be equipped with the stopper in the mounting hole, the screw rod runs through the mounting hole, and stopper sliding connection is in the spout. This arrangement allows the control screw to move only in the vertical direction.
Further, fixedly connected with gusset plate in the frame, the worm rotates to be connected on the gusset plate. The provision of the reinforcing plate makes the rotation of the turbine more stable.
Further, the top of frame is equipped with the backup pad, be equipped with circular shape recess in the backup pad, the turbine rotates to be connected in the recess. This arrangement makes the rotation of the turbine more stable.
Furthermore, a stop block is arranged at the top of the screw rod. A limiting block is arranged to prevent the screw from being separated from the turbine.
Further, a handle is fixedly connected to the worm. The use of the handle to turn the turbine is more labor-saving.
Further, the turbine is connected with a motor for driving the turbine to rotate, and the motor is fixedly connected with the reinforcing plate. The motor is more intelligent when in use.

fig. 2 is a schematic structural view of embodiment 2.
Detailed Description
The following is further detailed by the specific embodiments:
reference numerals in the drawings of the specification include: the device comprises a frame 1, a lower pressing plate 2, a loading plate 3, a screw rod 4, a sliding groove 5, a limiting block 6, a reinforcing plate 7, a handle 8, a worm 9, a supporting plate 10, a turbine 11, a stop block 12 and a motor 13.
The embodiment is basically as shown in the attached figure 1: an electrohydraulic pressure tester comprises a frame 1 and a driving component, a loading plate 3 is fixedly connected in the frame 1, a supporting plate 10 is arranged at the top of the frame 1, a circular groove is arranged on the supporting plate 10, the driving component comprises a screw rod 4 and a turbine 11, the turbine 11 is rotatably connected in the groove, a vertical chute 5 is arranged at the side edge of the screw rod 4, a mounting hole coaxial with the turbine 11 is arranged at the top of the frame 1, a limiting block 6 is arranged in the mounting hole, the screw rod 4 penetrates through the turbine 11 and the mounting hole and extends into the frame 1, the limiting block 6 is slidably connected in the chute 5, and screw rod 4 and turbine 11 threaded connection, screw rod 4 is located the one end fixedly connected with holding down plate 2 in frame 1, and the top of screw rod 4 is equipped with dog 12, and turbine 11 meshes has worm 9, fixedly connected with gusset plate 7 on the frame 1, and worm 9 rotates to be connected on gusset plate 7, and fixedly connected with handle 8 on the worm 9.
Use embodiment 1 as an example, during the use, drive turbine 11 through corotation worm 9 and rotate, because screw rod 4 and 11 meshes of turbine, frame 1 is again through stopper 6 and the vertical sliding connection of screw rod 4 simultaneously, therefore turbine 11 rotates screw rod 4 and can be driven and descend, and screw rod 4 vertical removal can drive holding down plate 2 and descend, and 11 chances of reversal turbine drive holding down plate 2 and rise.
