This equipment is usually used in the fields of material mechanical properties testing, metal tensile testing, concrete strength testing, etc. to improve test efficiency and accuracy.

[0003] In the prior art, most horizontal testing machines are usually equipped with only one set of motor oil pumps for operation, which causes the hydraulic oil to heat up quickly when the machine is working under load, affecting the test results.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a motor oil pump for rapid adjustment of the oil cylinder of a horizontal testing machine, comprising a test bed 1, a support frame 2 is arranged on an adjacent side of the test bed 1, a low-power motor 3 is fixedly connected to the upper surface of the support frame 2, an oil pipeline 5 is fixedly connected to the output end of the low-power motor 3, a high-power motor 4 is fixedly connected to the upper surface of the support frame 2, the output end of the high-power motor 4 is fixedly connected to the inside of the oil pipeline 5, an oil inlet pipe 6 is fixedly connected to the inside of the oil pipeline 5, an oil inlet pipe 6 is fixedly connected to the outer wall of the oil inlet pipe 6, and a cylinder body 7 is fixedly connected to the output end of the cylinder body 7 8. A water tank 9 is arranged directly below the oil pipeline 5. A water pump 10 is fixedly connected to the outer wall of the water tank 9. The input end of the water pump 10 is fixedly connected to the inside of the water tank 9. The output end of the water pump 10 is fixedly connected to the water pipeline 11. A cooling component is arranged on the outer wall of the water pipeline 11. A water collecting frame 27 is fixedly connected to the inside of the water tank 9. The cooling component includes a water spray pipe 12. The water spray pipe 12 is fixedly connected to the outer wall of the water pipeline 11. A shunt pipe 13 is fixedly connected to the inside of the water spray pipe 12. A support rod 14 is fixedly connected to the lower surface of the water spray pipe 12. The support rod 14 is fixedly connected to the upper surface of the oil pipeline 5.

[0024] Specifically, the low-power motor 3 is started to transport the oil to the inside of the oil pipe 5 through the output end of the low-power motor 3, and then transported to the inside of the cylinder body 7 through the oil pipe 5 and the oil inlet pipe 6. The cylinder body 7 is started to drive the slide plate 8 to slide back and forth on the outer wall of the connecting column 15. The high-power motor 4 is started to transport the oil to the inside of the oil pipe 5 through the output end of the high-power motor 4, and then transported to the inside of the cylinder body 7 through the oil pipe 5 and the oil inlet pipe 6. During the tensile test, generally only the low-power motor 3 is started to supply oil to the cylinder body 7, and the high-power motor 4 is a stopped working state, which prevents the low-power motor 3 and the high-power motor 4 from working at the same time to increase consumption. Starting only the low-power motor 3 to work at low power can not only reduce consumption but also play a role in cooling. At the same time, the water pump 10 is started to pump out the water inside the water tank 9 and transport it into the inside of the water pipe 11, and then transport it to the inside of the water spray pipe 12 through the water pipe 11, and finally split and spray it through the diverter pipe 13, which plays a role in cooling the oil pipe 5, thereby achieving the effect of rapid adjustment of the low-power motor 3 and the high-power motor 4 and cooling the oil pipe 5.

[0025] Reference Figure 1 and Figure 3 The interior of the test bed 1 is fixedly connected with a connecting column 15, the outer wall of the slide plate 8 is fixedly connected with a connecting plate 16, the upper surface of the connecting plate 16 is fixedly connected with a driving motor 17, the output end of the driving motor 17 is fixedly connected with a worm 18, the interior of the slide plate 8 is rotatably connected with a first worm gear 19, the first worm gear 19 is meshed with the worm 18, the outer wall of the first worm gear 19 is fixedly connected with a first connecting rod 20, and the outer wall of the first connecting rod 20 is rotatably connected with a first clamping block 22;

[0026] Specifically, the two connecting columns 15 fixed inside the test bed 1 play a limiting role. The driving motor 17 is started to drive the worm 18 to rotate. During the rotation of the worm 18, the first worm wheel 19 is driven to rotate. When the first worm wheel 19 rotates, it drives the first connecting rod 20 to rotate an angle. When the first connecting rod 20 rotates an angle, it also drives the first clamping block 22 to rotate an angle. The rotation angle of the first clamping block 22 drives the second connecting rod 21 to rotate an angle. The second connecting rod 21 rotates inside the slide plate 8, so that the first clamping block 22 can translate left and right.

[0027] Reference Figure 3 The interior of the slide plate 8 is rotatably connected to a second connecting rod 21, the second connecting rod 21 is rotatably connected to the interior of the first connecting rod 20, the interior of the slide plate 8 is rotatably connected to a second worm gear 23, the second worm gear 23 is meshed with the worm 18, the outer wall of the second worm gear 23 is fixedly connected to a third connecting rod 24, the outer wall of the third connecting rod 24 is rotatably connected to a second clamping block 26, the interior of the slide plate 8 is rotatably connected to a fourth connecting rod 25, the fourth connecting rod 25 is rotatably connected to the interior of the second clamping block 26;

[0028] Specifically, the worm 18 also drives the second worm gear 23 to rotate during the rotation process. The second worm gear 23 drives the third connecting rod 24 to rotate during the rotation, thereby driving the second clamping block 26 to rotate. When the second clamping block 26 rotates, it drives the fourth connecting rod 25 to rotate, thereby causing the second clamping block 26 to translate, so that the first clamping block 22 and the second clamping block 26 are clamped close to each other, the objects to be stretched are clamped and fixed, and the slide plate 8 is driven back and forth by the cylinder body 7 to slide for stretching.

[0029] Working principle: When a tensile test is required, two groups of clamping and fixing components are arranged inside the test bed 1, one of which is fixed on the left side of the test bed 1, and the other is fixed on the outer wall of the output end of the cylinder body 7. First, the object to be stretched is placed between the two groups of clamps, aligned between the first clamping block 22 and the second clamping block 26, and the drive motor 17 is started to drive the worm 18 to rotate. The worm 18 drives the first worm gear 19 and the second worm gear 23 to rotate respectively, and further drives the first connecting rod 20 and the third connecting rod 24 to rotate respectively, thereby driving the first clamping block 22 and the second clamping block 26 to rotate. Because of the limiting effect of the second connecting rod 21 and the fourth connecting rod 25 respectively, the first clamping block 22 and the second clamping block 26 are translated closer to each other, thereby clamping and fixing the object. At this time, the low-power motor 3 is started to supply oil to the inside of the oil pipe 5 through the output end of the low-power motor 3, and then the oil is transported into the inside of the oil cylinder body 7 through the oil inlet pipe 6. The oil cylinder body 7 is started to drive the slide plate 8 to slide back and forth for stretching. High temperature is easily generated during the stretching process, so the water pump 10 needs to be started at the same time during the tensile test. The water in the water tank 9 is pumped out through the input end of the water pump 10 and transported into the inside of the water pipe 11 through the output end, and then transported to the diversion pipe 13 through the water spray pipe 12 for diversion spraying, thereby cooling the oil pipe 5. When a high-power tensile test is required, the low-power motor 3 is turned off and the high-power motor 4 is started. The high-power motor 4 is used to supply oil to the oil cylinder body 7, and the water pump 10 is also started to cool the oil pipe 5, thereby achieving the effect of rapid adjustment and cooling.
