Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-6, the present utility model provides a technical solution: a hydraulic universal testing machine, including a test bench 1, on which a height adjustment component 2, a transmission component 3 and a clamping component 4 are respectively arranged.

The pipe bodies of the two chip inlet pipes 1004 extend into the inside of the glass protective cover 8, and the inlet ends are fixedly connected with chip inlets 1005. A take-off cover 1006 is movably connected to the upper surface of the chip collection box 1001. When the blower 1002 is turned on, small chips generated during the test are sucked into the chip collection box 1001 through the two chip inlets 1005 and the two chip inlet pipes 1004 for collection and storage, thereby reducing the consumption of the cleaning labor intensity of the staff. The protective filter screen 1003 effectively prevents chips from entering the blower 1002 and damaging it.

[0026] The height adjustment component 2 includes a first lead screw 201 rotatably connected to the upper surface of the test bench 1. An adjustment block 202 is threadedly connected to the rod body of the first lead screw 201.

A second bevel gear 302 is sleeved on the shaft body of the transmission shaft 301. The second bevel gear 302 meshes with the first bevel gear 203. A first motor 303 is installed on the back of the test bench 1. The output end of the first motor 303 is fixedly connected to the input end of the transmission shaft 301. When the first motor 303 is turned on, it drives the transmission shaft 301 and the second bevel gear 302 to rotate, and then drives the first bevel gear 203 and the first lead screw 201 to rotate, thereby driving the adjustment block 202 and the test component 5 to move up and down under the limitation of the limiting rod 204, realizing the adjustment of the height of the test component 5 according to the height of the metal material to be tested, and improving the practicability of the device.

Turn on the second motor 407 to drive the second lead screw 402 to rotate. Since the thread directions on the surfaces of both axial ends of the second lead screw 402 are opposite, the first rotating block 403 and the second rotating block 404 are driven to move towards the middle simultaneously under the limitation of the sliding groove 401, so that the two clamping plates 405 drive the first rubber anti-slip pads 406 to also move towards the middle simultaneously, clamping the metal material well, preventing the metal material from deviating from its original position, and improving the test efficiency.

[0028] The testing assembly 5 includes a connecting support plate 501 connected to the outer wall of the adjusting block 202. A hydraulic pump 502 is installed on the upper surface of the connecting support plate 501. A hydraulic telescopic rod 503 is installed on the lower surface of the connecting support plate 501.

Second rubber anti-slip pads 604 are embedded at the fixing ends of the two fixing blocks 603. Adjusting turntables 605 are connected to the ends of the two threaded rotating rods 602 far away from the fixing blocks 603. Rotate the two adjusting turntables 605 respectively, so that the two threaded rotating rods 602 drive the two fixing blocks 603 and the second rubber anti-slip pads 604 to move towards the middle simultaneously, fixing the upper end of the metal material. Turn on the hydraulic pump 502 to drive the hydraulic telescopic rod 503 to move up or down, thereby driving the metal material to move up and down, and completing various mechanical property tests such as stretching, compression, and bending, solving the problem of inconvenient testing by relying on manual adjustment and manual operation.

[0029] The stabilizing component 7 includes support legs 701 welded to the lower surface of the test bench 1. The number of support legs 701 is four, and the four support legs 701 are arranged in a rectangular array at the four corners of the lower surface of the test bench 1. Shock pads 702 are installed on the lower surfaces of the four support legs 701, and stabilizing blocks 703 are connected to the lower surfaces of the four shock pads 702. Threaded holes are provided on the four stabilizing blocks 703. By setting the support legs 701 and the shock pads 702, the stability of the device during use is increased. The device is fixed in place by means of the threaded holes provided on the four stabilizing blocks 703, further increasing the stability of the device during use.

[0030] Working principle: During use, the first motor 303 is turned on to drive the transmission shaft 301 and the second helical gear 302 to rotate, thereby driving the first helical gear 203 and the first lead screw 201 to rotate, and then driving the adjusting block 202 and the test component 5 to move up and down under the limitation of the limiting rod 204, so as to adjust the height of the test component 5 according to the height of the metal material to be tested, improving the practicability of the device. After adjusting to the appropriate distance, the first motor 303 is turned off, and the metal material to be tested is placed on the upper surface of the test bench 1. The second motor 407 is turned on to drive the second lead screw 402 to rotate. Since the thread directions on the surfaces of the two ends of the second lead screw 402 along its axis are opposite, the first rotating block 403 and the second rotating block 404 are driven to move towards the middle simultaneously under the limitation of the sliding groove 401, so that the two clamping plates 405 drive the first rubber anti-slip pads 406 to also move towards the middle simultaneously, clamping the metal material well and preventing the metal material from deviating from its original position, improving the test efficiency. The two adjusting turntables 605 are rotated respectively, so that the two threaded rods 602 drive the two fixing blocks 603 and the second rubber anti-slip pads 604 to move towards the middle simultaneously, fixing the upper end of the metal material. The hydraulic pump 502 is turned on to drive the hydraulic telescopic rod 503 to move up or down, thereby driving the metal material to move up and down, completing various mechanical property tests such as tension, compression, and bending, and solving the problem of inconvenient testing by relying on manual adjustment. The blower 1002 is turned on, and the small pieces of debris generated during the test are sucked into the debris collection box 1001 through the two chip inlets 1005 and the two chip inlet pipes 1004 for collection and storage, thereby reducing the consumption of the cleaning labor intensity of the staff. The protective filter net 1003 effectively prevents debris from entering the blower 1002 and damaging it.
