Description

Technical Field

[0001] The present invention relates to the technical field of insulating cylinder production parts, and particularly to a combined testing machine for inspecting insulating cylinders. Background Art

[0002] An insulating cylinder is an insulating material mainly used in electrical equipment to prevent electric power leakage and the generation of electric sparks, ensuring the safety of operators. It is widely used in interior decoration and urban construction, especially performing well in high-voltage vacuum circuit breakers; Since insulating cylinders are widely used outdoors, during the production process of insulating cylinders, various different detections need to be carried out on the insulating cylinders. First, the insulating cylinder to be detected is cut, and a small part of it is selected as a sample. The sample is installed on the testing machine, and the testing machine is started to begin the corresponding detections. However, in the actual detection process, the traditional detection can only complete one type of detection operation on the insulating cylinder, and can only perform separate tensile, bending, and extrusion detections on the insulating cylinder, and cannot perform combined detections. At the same time, during the testing, it is carried out in a relatively enclosed space indoors. Since most insulating cylinders are installed outdoors, especially at high altitudes, the environment is relatively harsh, and there is no simulation operation of the environment where the insulating cylinder is located, resulting in most of the experimental detection results being theoretical results, with a certain gap from the actual results. Therefore, a combined testing machine for inspecting insulating cylinders is provided. Summary of the Invention

Detailed implementation

[0014] Refer to Figures 1-11 , a combined testing machine for inspecting an insulating cylinder, including a body 1, a bracket is fixedly connected to the lower side of the body 1, a plurality of buffer pads are fixedly connected to the lower side of the bracket, a fixed seat 2 is fixedly connected to the upper side inside the body 1, a first hydraulic rod 3 is fixedly connected to the lower side inside the body 1, an extrusion test plate 4 is fixedly connected to the output end of the first hydraulic rod 3, a fixed ring 11 is installed on the body 1, and a clamping assembly is installed on the fixed ring 11; First, when detection is required, the sample to be detected is installed on the clamping assembly and the sample is in a slightly taut state. At this time, the first hydraulic rod 3 is started, and the first hydraulic rod 3 drives the extrusion test plate 4 to move downward. The extrusion test plate 4 abuts against the sample and forms extrusion on the sample, and the extrusion test of the sample is started. After a period of time, the first hydraulic rod 3 is turned off to make the first hydraulic rod 3 return to its original position, the sample is taken off, and the damaged degree of the sample is checked. The detection is carried out multiple times, and the force of the extrusion test plate 4 on the sample is adjusted during each experiment. The experimental data is statistically analyzed, and finally the extrusion test effect of the sample is completed; The clamping assembly includes an internal thread cylinder 5 fixedly penetrating through the fixed ring 11. A plurality of clamping rods 6 are slidably penetrated through the side walls of the two internal thread cylinders 5. A first frustum 7 is fixedly connected to one side of each clamping rod 6 inside the internal thread cylinder 5. A first spring 8 is fixedly connected between the first frustum 7 and the internal thread cylinder 5. A first external threaded rod 9 is also threadedly connected inside the internal thread cylinder 5. A second frustum 10 is fixedly connected to one side of the first external threaded rod 9 inside the internal thread cylinder 5. The second frustum 10 abuts against the first frustum 7. An anti-slip sleeve is fixedly connected to the side of the clamping rod 6 away from the internal thread cylinder 5, and the anti-slip sleeve is circularly arranged; First, when clamping the sample is required, both ends of the sample are sleeved outside the internal thread cylinder 5, and the clamping rods 6 outside the internal thread cylinder 5 are also located inside the sample. While holding the internal thread cylinder 5, rotate the first external threaded rod 9 to move the first external threaded rod 9 relative to the internal thread cylinder 5. The first external threaded rod 9 drives the second conical platform 10 to move. The second conical platform 10 abuts against the first conical platform 7, forming an extrusion on the first conical platform 7 and causing the first conical platform 7 to move away from the internal thread cylinder 5. While the first conical platform 7 compresses the first spring 8, it drives the clamping rod 6 until the left and right clamping rods 6 tightly abut against the sample, thereby completing the clamping and fixing operation of the sample; A control component for controlling the movement of the fixed ring 11 is installed on the upper side of the body 1. The control component includes a sliding cylinder 17 rotatably connected to the fixed ring 11. Two installation grooves 36 are symmetrically opened on the upper side of the body 1. The two sliding cylinders 17 are slidably connected to the installation grooves 36. The sliding cylinder 17 is rotatably connected to the fixed ring 11. A return spring is fixedly connected between the sliding cylinder 17 and the installation groove 36. A positioning rod 18 is slidably connected inside the sliding cylinder 17. A second spring 20 is fixedly connected between the positioning rod 18 and the sliding cylinder 17. An inclined head rod 19 is fixedly connected to the side wall of the positioning rod 18, and the inclined head rod 19 penetrates through the sliding cylinder 17. Positioning grooves are opened at the bottom of both installation grooves 36. One end of the positioning rod 18 extends into the positioning groove. A sliding plate 14 is slidably connected to the upper side of the body 1. Second hydraulic rods 12 are fixedly connected to both sides of the sliding plate 14. The output ends of the two second hydraulic rods 12 are fixedly connected with push plates 13. A moving head 31 is fixedly connected to the side wall of the push plate 13. A second external threaded rod 15 is rotatably connected to the side wall of the fixed seat 2. The second external threaded rod 15 threadedly penetrates through the sliding plate 14; First, in the initial state, the lower end of the positioning rod 18 is located in the positioning groove in the installation groove 36, and the return spring is in a stretched state. Secondly, before the test, first determine whether to conduct a tensile test or a bending test on the sample according to the actual work requirements. When a tensile test is required, rotate the second external threaded rod 15. Since the sliding plate 14 and the body 1 are slidably connected, rotating the second external threaded rod 15 will drive the sliding plate 14 to move relative to the body 1, as Figure 5As shown, it will cause the skateboard 14 to move back and forth relative to the main body 1. The skateboard 14 drives the second hydraulic rod 12 and the push plate 13 to move back and forth relative to the main body 1. The push plate 13 drives the moving head 31 to move until the positions of the push plate 13 and the inclined head rod 19 are opposite. Then, the second hydraulic rod 12 is started. The second hydraulic rod 12 drives the push plate 13 and the moving head 31 to move away from the fixed seat 2. The push plate 13 abuts against the inclined head rod 19. Under the blocking effect of the positioning groove, it will first drive the inclined head rod 19 to move upward relative to the sliding cylinder 17. While the inclined head rod 19 drives the positioning rod 18 to move upward, the second spring 20 is compressed until the positioning rod 18 moves out of the positioning groove. At this time, without the blocking effect of the positioning groove, it will cause the sliding cylinder 17, the fixed ring 11 and the internal thread cylinder 5 to move away from the fixed seat 2. The internal thread cylinder 5 drives the clamping rod 6 and the sample to move away from the fixed seat 2, forming a stretching effect on the sample. The second hydraulic rod 12 is started repeatedly for multiple times to form multiple stretching operations, and the magnitude of the stretching force is different each time. The experimental data is statistically analyzed, and finally the stretching test effect of the sample is completed. Here, it should be noted that when the push plate 13 abuts against the inclined head rod 19, the inclined head rod 19 will be squeezed to an extreme position, which is the position where the positioning rod 18 moves out of the positioning groove. At this time, the push plate 13 still abuts against the inclined head rod 19, and it will cause the sliding cylinder 17, the fixed ring 11 and the internal thread cylinder 5 to move by applying a force to the inclined head rod 19. And in this state, there is still a gap between the moving head 31 and the fixed ring 11, and the two will not abut against each other; When a bending test needs to be performed on the sample, still rotate the second external threaded rod 15. Different from the above, the moving distance of the moving head 31 driven by the push plate 13 is changed. This time, the positions of the push plate 13 and the moving head 31 are staggered from the position of the sliding cylinder 17, that is, when the push plate 13 drives the moving head 31 to move left and right, the push plate 13 will not abut against the sliding cylinder 17 when moving, but the moving head 31 will abut against the fixed ring 11. At this time, the second hydraulic rod 12 is started. The second hydraulic rod 12 drives the push plate 13 and the moving head 31 to move away from the fixed seat 2. The moving head 31 abuts against the fixed ring 11. Under the blocking effect of the positioning groove and the positioning rod 18, the whole fixed ring 11 will not move. Therefore, when the moving head 31 abuts against the fixed ring 11, it will cause the whole fixed ring 11 and the internal thread cylinder 5 to rotate around the sliding cylinder 17. The internal thread cylinder 5 drives the clamping rod 6 to rotate around the sliding cylinder 17, and then the clamping rods 6 on both sides rotate in opposite directions, and finally the sample will be bent. The second hydraulic rod 12 is started repeatedly for multiple times to form multiple bending operations, and the magnitude of the bending force is different each time. The experimental data is statistically analyzed, and finally the bending test effect of the sample is completed.

[0015] A friction simulation component is installed on the upper side of the fixed seat 2. The friction simulation component includes two arc-shaped plates 21. Two control plates 28 are slidably connected to the side walls of the two arc-shaped plates 21. A connecting plate 26 is fixedly connected to the side walls of the two control plates 28. A third spring 27 is fixedly connected between the connecting plate 26 and the arc-shaped plate 21. Fixed plates 29 are fixedly connected to the lower sides of the two arc-shaped plates 21. A connecting rod 24 is fixedly connected to the side wall of the fixed plate 29. Two moving frames 16 are slidably connected to the upper side of the body 1. The push plate 13 slidably penetrates through the moving frame 16. One end of the connecting rod 24 extending into the moving frame 16 is fixedly connected to a circular plate 34. A plurality of moving blocks 35 are fixedly connected to the outer circumference of the circular plate 34. A plurality of moving plates 30 are evenly fixedly connected to the side wall of the push plate 13; First, when adjusting the position of the moving head 31, the push plate 13 drives the moving plate 30 to move. When the moving plate 30 abuts against the moving block 35, it will cause the moving block 35 to rotate around the connecting rod 24. The moving block 35 drives the circular plate 34 and the connecting rod 24 to rotate. The connecting rod 24 drives the fixed plate 29 and the arc-shaped plate 21 to rotate. During this process, when the arc-shaped plate 21 rotates, the arc-shaped plate 21 drives the control plate 28 to abut against the sample, which will form an extrusion and friction effect on the sample, simulating the actual use environment of the sample, and thus improving the subsequent detection effect.

[0016] A knocking simulation component is installed on the upper side of the arc-shaped plate 21. The knocking simulation component includes a plurality of knocking protrusions 25 fixedly installed on the inner side of the arc-shaped plate 21. A rotating ring 32 is rotatably connected to the outer side of the connecting rod 24. The rotating ring 32 is slidably connected to the moving frame 16. A fourth spring 33 is fixedly connected between the rotating ring 32 and the moving frame 16. A chute 22 is opened on the upper side of the fixed seat 2. A plurality of trapezoidal plates 23 are evenly fixedly connected to the upper side in the chute 22; First, when performing tensile or bending tests, the push plate 13 drives the moving frame 16 to move left and right. The moving frame 16 drives the connecting rod 24, the fixed plate 29 and the arc-shaped plate 21 to move through the rotating ring 32. During this process, under the action of the fourth spring 33, the fixed plate 29 always abuts against the chute 22 or the trapezoidal plate 23. Therefore, during this process, when the fixed plate 29 moves from abutting against the chute 22 to abutting against the trapezoidal plate 23, and when the fixed plate 29 moves from abutting against the trapezoidal plate 23 to abutting against the chute 22, it will cause the arc-shaped plate 21 to move up and down relative to the fixed seat 2. The arc-shaped plate 21 drives the knocking protrusions 25 to move up and down. The knocking protrusions 25 abut against the sample, which will form a knocking effect on the sample, thus enriching the simulation effect and ultimately improving the subsequent detection effect.

[0017] In the present invention, when it is necessary to perform a clamping operation on a sample, both ends of the sample are sleeved outside the internal thread cylinder 5, and the clamping rods 6 outside the internal thread cylinder 5 are also located inside the sample. While holding the internal thread cylinder 5, rotate the first external threaded rod 9 so that the first external threaded rod 9 moves relative to the internal thread cylinder 5. The first external threaded rod 9 drives the second frustum 10 to move. The second frustum 10 abuts against the first frustum 7, forming an extrusion on the first frustum 7 and causing the first frustum 7 to move away from the internal thread cylinder 5. While the first frustum 7 compresses the first spring 8, it drives the clamping rod 6 until the left and right clamping rods 6 tightly abut against the sample, thereby completing the clamping and fixing operation of the sample; Start the first hydraulic rod 3. The first hydraulic rod 3 drives the extrusion test plate 4 to move downward. The extrusion test plate 4 abuts against the sample and forms an extrusion on the sample, starting the extrusion test on the sample. After a period of time, turn off the first hydraulic rod 3 to make the first hydraulic rod 3 return to its original position, remove the sample, check the damage degree of the sample, conduct the detection multiple times, and adjust the acting force of the extrusion test plate 4 on the sample during each experiment. Statistically analyze the experimental data, and finally complete the extrusion test effect on the sample; When a tensile test is required, rotate the second external threaded rod 15. Since the sliding plate 14 is slidably connected to the main body 1, rotating the second external threaded rod 15 will drive the sliding plate 14 to move relative to the main body 1. As Figure 5 shown, it will cause the sliding plate 14 to move back and forth relative to the main body 1. The sliding plate 14 drives the second hydraulic rod 12 and the push plate 13 to move back and forth relative to the main body 1. The push plate 13 drives the moving head 31 to move until the push plate 13 and the inclined head rod 19 are in relative positions. Then, start the second hydraulic rod 12. The second hydraulic rod 12 drives the push plate 13 and the moving head 31 to move away from the fixed seat 2. The push plate 13 abuts against the inclined head rod 19. Under the blocking action of the positioning groove, it will first drive the inclined head rod 19 to move upward relative to the sliding cylinder 17. While the inclined head rod 19 drives the positioning rod 18 to move upward, it compresses the second spring 20 until the positioning rod 18 moves out of the positioning groove. At this time, without the blocking action of the positioning groove, it will cause the sliding cylinder 17, the fixed ring 11, and the internal thread cylinder 5 to move away from the fixed seat 2. The internal thread cylinder 5 drives the clamping rod 6 and the sample to move away from the fixed seat 2, forming a tensile effect on the sample. Repeat starting the second hydraulic rod 12 multiple times to form multiple tensile operations, and the magnitude of the tensile force is different each time. Statistically analyze the experimental data, and finally complete the tensile test effect on the sample; When a bending test needs to be performed on a sample, the second outer threaded rod 15 is rotated. Different from the above, the moving distance of the moving head 31 driven by the push plate 13 is changed. This time, the positions of the push plate 13 and the moving head 31 are offset from the position of the sliding cylinder 17. That is, when the push plate 13 drives the moving head 31 to move to the left and right, the push plate 13 will not abut against the sliding cylinder 17 during movement, but the moving head 31 will abut against the fixed ring 11. At this time, the second hydraulic rod 12 is started, and the second hydraulic rod 12 drives the push plate 13 and the moving head 31 to move away from the fixed seat 2. The moving head 31 abuts against the fixed ring 11. Under the blocking action of the positioning groove and the positioning rod 18, the entire fixed ring 11 will not move. Therefore, when the moving head 31 abuts against the fixed ring 11, it will cause the fixed ring 11 and the internal threaded cylinder 5 to rotate around the sliding cylinder 17 as the center. The internal threaded cylinder 5 drives the clamping rod 6 to rotate around the sliding cylinder 17 as the center, and then causes the clamping rods 6 on both sides to rotate in opposite directions, and finally causes the sample to bend. The second hydraulic rod 12 is started repeatedly for many times to form multiple bending operations, and the magnitude of the bending force is different each time. The experimental data is statistically analyzed, and finally the bending test effect of the sample is completed; When adjusting the position of the moving head 31, the push plate 13 drives the moving plate 30 to move. The moving plate 30 abuts against the moving block 35, which will cause the moving block 35 to rotate around the connecting rod 24 as the center. The moving block 35 drives the circular plate 34 and the connecting rod 24 to rotate. The connecting rod 24 drives the fixed plate 29 and the arc plate 21 to rotate. During this process, when the arc plate 21 rotates, the arc plate 21 drives the control plate 28 to abut against the sample, which will form an extrusion and friction effect on the sample, simulate the actual use environment of the sample, and thus improve the subsequent detection effect; When performing tensile or bending tests, the push plate 13 drives the moving frame 16 to move left and right. The moving frame 16 drives the connecting rod 24, the fixed plate 29 and the arc plate 21 to move through the rotating ring 32. During this process, under the action of the fourth spring 33, the fixed plate 29 always abuts against the chute 22 or the trapezoidal plate 23. Therefore, during this process, when the fixed plate 29 moves from abutting against the chute 22 to abutting against the trapezoidal plate 23, and when the fixed plate 29 moves from abutting against the trapezoidal plate 23 to abutting against the chute 22, it will cause the arc plate 21 to move up and down relative to the fixed seat 2. The arc plate 21 drives the knocking protrusion 25 to move up and down. The knocking protrusion 25 abuts against the sample, which will form a knocking effect on the sample, and thus enrich the simulation effect and finally improve the subsequent detection effect.
