[0025] See also Figure 1-3 , the utility model provides a technical solution: a multifunctional hydraulic testing platform, including a testing workbench 1, a testing component and a clamping component;

[0026] The test assembly is set on the test workbench 1, and the test assembly includes a tester 2, a threaded hole 4, a connecting column 5, a pressure measuring joint 6 and a threaded rod 7. The tester 2 is installed on the test workbench 1, and the threaded hole 4 is opened on the tester 2;

[0027] The clamping assembly is arranged on the test workbench 1, and the clamping assembly includes two arc-shaped clamping parts 9, a sliding groove 10, two threaded sleeves 11, a bidirectional screw 12, two guide sleeves 13, two connecting parts 14, two threaded columns 15, two knobs 16 and two clamping rods 17. The sliding groove 10 is opened on the test workbench 1, and the two connecting parts 14 slide along the inside of the sliding groove 10. The two connecting parts 14 are respectively fixedly sleeved on the corresponding guide sleeves 13, and the two clamping rods 17 slide along the inside of the corresponding guide sleeves 13. The two arc-shaped clamping parts 9 are respectively welded to the opposite surfaces of the corresponding clamping rods 17.

[0030] The two connecting members 14 are respectively fixedly sleeved on the corresponding threaded sleeves 11 , and the sponge pads 8 are fixedly adhered to the opposite surfaces of the two arc-shaped clamping members 9 .

[0031] The two threaded columns 15 are respectively connected to the corresponding guide sleeves 13 by threads, and the two threaded columns 15 are respectively in contact with the surface of the corresponding clamping rod 17.

[0033] When it is necessary to clamp the device to be tested;

[0034] First, place the device to be tested between the two sponge pads 8. Then, start the tester 2 through an external power supply. The start-up of the tester 2 drives the bidirectional screw 12 to rotate. The rotation of the bidirectional screw 12 drives the two threaded sleeves 11 to move. The movement of the two threaded sleeves 11 drives the corresponding connecting parts 14 to move relative to each other along the inside of the sliding groove 10. The relative movement of the two connecting parts 14 drives the corresponding threaded columns 15 to move. The movement of the two threaded columns 15 drives the corresponding clamping rods 17 to move. The movement of the two clamping rods 17 drives the corresponding arc-shaped clamping parts 9 to move relative to each other. The relative movement of the two arc-shaped clamping parts 9 drives the corresponding sponge pads 8 to move relative to each other to clamp the device to be pressure tested.

[0035] When it is necessary to adjust the clamping position of the device to be tested;

[0036] First, the two knobs 16 are driven to move by external force, and the movement of the two knobs 16 drives the corresponding threaded column 15 to move to loosen the clamping rod 17. Then, the two clamping rods 17 are driven to move by external force, and the movement of the two clamping rods 17 drives the corresponding arc-shaped clamping parts 9 to move, and the movement of the two arc-shaped clamping parts 9 drives the corresponding sponge pads 8 to move to adjust the position of the device to be pressure measured clamped by the two sponge pads 8 to a suitable position. Then, the two knobs 16 are driven to move by external force, and the movement of the two knobs 16 drives the corresponding threaded column 15 to move to tighten the position of the two clamping rods 17.

[0037] Working principle:

[0038] When it is necessary to adjust the device for testing different diameters;

[0039] First, the connecting column 5 is driven to move by an external force, and the movement of the connecting column 5 drives the threaded rod 7 to move to replace the pressure measuring joints 6 of different sizes to test devices of different diameters.

[0040] By setting two knobs 16 in the clamping assembly, the two sponge pads 8 can be loosened by turning the two knobs 16, thereby adjusting the position of the device to be tested, ensuring that the position of the device to be tested and its pressure measuring joint 6 are consistent, thereby avoiding the problem of being unable to perform testing when the test port of the device to be tested is not in the center position, thereby expanding the scope of application of the devices that can be tested by the test platform, that is, expanding the practicality of the test platform.

[0041] By setting a connecting column 5 in the test assembly, the connecting column 5 can drive the threaded rod 7 to move out of the inside of the threaded hole 4, thereby replacing pressure measuring joints 6 of different sizes to adapt to devices to be tested with different diameters, thereby expanding the scope of application of the test platform.

[0042] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
