[0062] Reference Appendix Figures 1-9 This application provides a push-pull force detection system, including a base 100, a support device 200, a sliding device 300, and a first sensor 400; wherein the base 100 is disposed on a horizontal plane, the support device 200 includes a fixing member 201 and a limiting member 202, the fixing member 201 is fixed to the top surface of the base 100, and at least one limiting member 202 is fixed to the side wall of the fixing member 201; the sliding device 300 includes two sliding members 301, a first push-pull member 302, and a second push-pull member 303, and a limiting member 403 passes through the sliding members 301. The positioning groove 307 is slidably sleeved outside the limiting member 202. The first push-pull member 302 and the second push-pull member 303 are respectively fixed at both ends of the two sliding members 301. The two sliding members 301, the first push-pull member 302, and the second push-pull member 303 together form an accommodating space. The fixing member 201 divides the accommodating space into a first space and a second space. The first sensor 400 is located on the side of the first push-pull member 302 away from the fixing member 201 and is connected to it. The first sensor 400 is electrically connected to a control console 1200.

[0063] Reference Appendix Figures 1-3 In some embodiments, the base 100 is a tooling frame, and the base 100 includes a top rod and a mounting surface. The mounting surface is located at the end of the top rod away from the horizontal plane and is parallel to the horizontal plane.

[0064] The top rod is used to support the mounting platform so that it is at a suitable height, making the installation or testing process more convenient for the testing personnel; the mounting platform is used to provide a horizontal base surface for the testing operation.

[0065] Reference Appendix Figures 4-6 In some embodiments, the support device 200 includes a fixing member 201, a limiting member 202, a mounting base 203, an auxiliary member 204, and a support member 205.

[0066] The fixing member 201 is a plate-shaped component, which is fixedly disposed on the top surface of the base 100. The fixing member 201 includes a first side wall and a second side wall that are disposed opposite to each other, as well as a third side wall and a fourth side wall that are disposed opposite to each other. The area of ​​the first side wall and the second side wall is larger than the area of ​​the third side wall and the fourth side wall. The first side wall faces the first sensor 400. At least one limiting member 202 is fixedly disposed on the third side wall or the fourth side wall of the fixing member 201. The limiting member 202 is a boss that is perpendicular to the third side wall or the fourth side wall.

[0067] The fixing member 201 is used to limit the horizontal displacement of the sliding device 300, so that the sliding device 300 will no longer move when it comes into contact with the first side wall or the second side wall; the limiting member 202 is used to limit the displacement of the sliding device 300 in the direction perpendicular to the horizontal plane, so that the sliding device 300 reciprocates along the direction from the first side wall to the second side wall.

[0068] It should be noted that the number of limiting members 202 should be set according to the actual situation. The more limiting members 202 there are, the more stably the sliding device 300 can be restricted from displacement in the direction perpendicular to the horizontal plane. In some embodiments, limiting members 202 are respectively provided on the third side wall and the fourth side wall so that the sliding device 300 cannot be displaced in the direction perpendicular to the horizontal plane, and the sliding device 300 reciprocates along the direction from the first side wall to the second side wall.

[0069] In some embodiments, the mounting base 203 is a plate-shaped component, fixedly mounted on the top surface of the base 100, and the fixing member 201 is fixedly mounted on the top surface of the mounting base 203. The top surface of the mounting base 203 is parallel to the top surface of the base 100. The auxiliary member 204 is a rib, and two auxiliary members 204 are fixedly mounted on the top surface of the mounting base 203 and located on both sides of the fixing member 201. The two auxiliary members 204 are fixedly connected to the fixing member 201. The support member 205 is a plate-shaped component, and the top surface of the support member 205 is parallel to the top surface of the mounting base 203.

The two support members 205 are located in the first space and the second space, respectively.

[0070] Mounting base 203 is used to adjust the height of fixing member 201 and support member 205 relative to base 100, so that fixing member 201 and support member 205 are more convenient to use for detection; auxiliary member 204 is used to stabilize the relative position of fixing member 201 and base plate, and auxiliary member 204 is also used to support and stabilize support member 205, so that support member 205 and mounting base 203 maintain a certain height, and the positional relationship between support member 205 and fixing member 201 remains stable; support member 205 is used to support second sensor 500 and third sensor 600, so that second sensor 500 and third sensor 600 maintain a certain height relative to mounting base 203, thereby reducing the detection error of second sensor 500 and third sensor 600 during detection.

[0071] It should be noted that the number of auxiliary components 204 is set according to the actual situation. The more auxiliary components 204 there are, the more stable the relative position of the fixing component 201 and the base 100 will be. In some embodiments, four auxiliary components 204 are arranged opposite to each other on both sides of the fixing component 201.

[0072] Reference Appendix Figures 7-9 In some embodiments, the sliding device 300 includes two sliding members 301, a first push-pull member 302, and a second push-pull member 303. A limiting groove 307 is provided on the sliding member 301. The two sliding members 301 are slidably sleeved on the limiting member 202 through the limiting groove 307. The first push-pull member 302 and the second push-pull member 303 are respectively fixed at both ends of the two sliding members 301. The two sliding members 301, the first push-pull member 302, and the second push-pull member 303 together form an accommodating space. The fixing member 201 divides the accommodating space into a first space and a second space.

[0073] Among them, the sliding member 301 is a plate-shaped component. The sliding member 301 is located on one side of the third or fourth side wall. A limiting groove 307 is provided on the sliding member 301. The inner diameter of the limiting groove 307 in the horizontal direction is larger than that of the limiting member 202, and the inner diameter of the limiting groove 307 in the vertical direction is also larger than that of the limiting member 202. The two sliding members 301 are slidably sleeved on the outside of the limiting member 202 through the limiting groove 307, so that the sliding member 301 can slide relative to the fixed member 201, and the displacement of the sliding member 301 is restricted.

[0074] The first push-pull member 302 and the second push-pull member 303 are plate-shaped components. The first push-pull member 302 is located on one side of its first sidewall relative to the fixing member 201, and the second push-pull member 303 is located on one side of its second sidewall relative to the fixing member 201. The first push-pull member 302 and the second push-pull member 303 are located at both ends of the two sliding members 301. The first push-pull member 302 and the second push-pull member 303 are respectively connected to the two sliding members 301. The two sliding members 301, the first push-pull member 302, and the second push-pull member 303 together form an accommodating space. The fixing member 201 divides the accommodating space into a first space and a second space. The two supporting members 205 are respectively located below the first space and the second space.

[0075] When the first push-pull member 302 slides from the first sidewall to the second sidewall, the second push-pull member 303 slides from the first sidewall to the second sidewall, the volume of the first space decreases, and the volume of the second space increases; when the first push-pull member 302 slides from the second sidewall to the first sidewall, the second push-pull member 303 slides from the second sidewall to the first sidewall, the volume of the first space decreases, and the volume of the second space increases.

[0076] The first space and the second space are used to accommodate the second sensor 500 and the third sensor 600, respectively, so as to facilitate the assembly and disassembly of the second sensor 500 and the third sensor 600; the first push-pull member 302 and the second push-pull member 303 are used to squeeze the second sensor 500 and the third sensor 600, so that the second sensor 500 and the third sensor 600 can simultaneously receive the push or pull force attached to the first sensor 400.

[0078] The first sensor 400, the second sensor 500, and the third sensor 600 are push-pull force sensors. The first sensor 400 is located between the power device 1300 and the sliding device 300. When the power device 1300 pushes or pulls the sliding device 300 relative to the support device 200, the first sensor 400 is used to detect the push or pull force provided by the power device 1300. When the sliding device 300 is restricted by the support device 200 and cannot follow the movement of the power device 1300, the first sensor 400 is used to detect the maximum value of the push or pull force provided by the power device 1300.

[0079] The second sensor 500 is disposed in the first space, located between the first push-pull member 302 and the first side wall. When the power device 1300 pushes the first push-pull member 302 and the second sensor 500 close to the first side wall, the second sensor 500 is used to detect the thrust provided by the power device 1300. When the power device 1300 pushes the first push-pull member 302 and the second sensor 500 are pressed tightly against the first side wall, the second sensor 500 is used to detect the maximum value of the thrust provided by the power device 1300. By determining whether the detection value of the second sensor 500 is equal to the detection value of the first sensor 400, the first sensor 400 is verified to be qualified.

When the power device 1300 pulls the second push-pull member 303 and the third sensor 600 approaches the second side wall, the third sensor 600 is used to detect the pulling force provided by the power device 1300. When the power device 1300 pulls the second push-pull member 303 and the third sensor 600 is pressed against the second side wall, the third sensor 600 is used to detect the maximum value of the pulling force provided by the power device 1300. By determining whether the detection value of the third sensor 600 is equal to the detection value of the first sensor 400, the first sensor 400 is verified to be qualified.

The control console 1200 includes a control center and a pump station. The control center is used to read the values ​​detected by the first sensor 400, the second sensor 500, and the third sensor 600.

[0092] The mounting bracket 1000 is a plate-shaped component. The mounting bracket 1000 has a mounting groove 1001 perpendicular to the horizontal direction. The mounting bracket 1000 is used to mount the power device 1300. The actuating end of the power device 1300 passes through the mounting groove 1001 and is connected to the third connector 900.

[0096] This application also provides a detection method for a push-pull force detection system, which performs the detection based on the push-pull force detection system of specific embodiment one, including:

[0097] In the power activation step, the power device 1300 is activated via the control panel 1200, causing the power device 1300 to push or pull the sliding device 300. The first push-pull member 302 moves closer to or further away from the fixed member 201, and the corresponding second push-pull member 303 moves further away from or closer to the fixed member 201.

[0098] In the thrust detection step, when the side wall of the first push-pull member 302 is in contact with the side wall of the fixed member 201, the electrical signal fed back by the first sensor 400 reaches its maximum value, and the maximum thrust value fed back by the first sensor 400 is read through the control console 1200.

[0099] In the tensile force detection step, when the side wall of the second push-pull member 303 is in contact with the side wall of the fixing member 201, the electrical signal fed back by the first sensor 400 reaches its maximum value, and the maximum tensile force fed back by the first sensor 400 is read through the control console 1200.

[0100] The data verification step determines whether the standard value of power unit 1300 is equal to the measured value. If yes, power unit 1300 is qualified; otherwise, it is unqualified.

[0101] It should be noted that the measured values ​​in the data verification step include the maximum thrust and maximum tension values ​​measured by the first sensor 400. The standard values ​​of the power unit 1300 are the maximum thrust reference value and the maximum tension reference value given at the factory. In order to ensure the accuracy of the power unit 1300, it is usually necessary to compare the measured maximum thrust and maximum tension values ​​with the maximum thrust reference value and the maximum tension reference value, respectively. Only when they are equal can the power unit 1300 be considered qualified. However, in special cases, it is only necessary for the power unit 1300 to provide qualified thrust or tension. Therefore, it is only necessary to determine that the measured maximum thrust value is equal to the maximum thrust reference value to be considered qualified, or the measured maximum tension value is equal to the maximum tension reference value to be considered qualified.

[0102] During the actual testing process, the testing personnel installed the power unit 1300 on the mounting bracket 1000 and electrically connected it to the control console 1200. The actuating end of the power unit 1300 passed through the mounting groove 1001 and connected to the third connector 900. The power unit 1300 was turned on by the control console 1200, causing the power unit 1300 to rotate forward to push or reverse to pull the third connector 900 to move, thereby transmitting power sequentially to the first sensor 400, the second connector 700, the first connector 304, and the first push-pull member 302. The first push-pull member 302 moved closer to or away from the fixing member 201, and the corresponding second push-pull member 303 moved away from or closer to the fixing member 201.

[0103] When the first push-pull member 302 is in contact with the first side wall of the fixing member 201, the support device 200 and the sliding device 300 no longer move relative to each other. At this time, the thrust received by the first sensor 400 reaches its maximum value. By reading the thrust received by the first sensor 400 at this time through the control console 1200, the maximum thrust output by the power device 1300 can be obtained. The measured maximum thrust is compared with the standard maximum thrust of the power device 1300. If the two are equal, the power device 1300 is qualified. If the two are not equal, the power device 1300 is unqualified.

[0104] When the side wall of the second push-pull member 303 is in contact with the second side wall of the fixing member 201, the support device 200 and the sliding device 300 no longer move relative to each other, and the tension on the first sensor 400 reaches its maximum value. By reading the tension on the first sensor 400 at this time through the control console 1200, the maximum value of the tension output by the power device 1300 can be obtained. The measured maximum value of the tension is compared with the standard maximum value of the tension of the power device 1300. If the two are equal, the power device 1300 is qualified; if the two are not equal, the power device 1300 is unqualified. Specific Implementation Example 3

[0106] This application also provides a detection method for a push-pull force detection system, which verifies the push-pull force detection system based on the specific embodiment one, including:

[0107] In the power activation step, the power device 1300 is activated via the control panel 1200, causing the power device 1300 to push or pull the sliding device 300. The first push-pull member 302 moves closer to or further away from the fixed member 201, and the corresponding second push-pull member 303 moves further away from or closer to the fixed member 201.

[0108] In the thrust detection step, the second sensor 500 is pushed to the side wall of the fixing member 201 by the first push-pull member 302. When the electrical signals fed back by the first sensor 400 and the second sensor 500 reach their maximum values, the maximum thrust values ​​fed back by the first sensor 400 and the second sensor 500 are read by the control console 1200.

[0109] In the tensile force detection step, the third sensor 600 is pulled to the side wall of the fixing member 201 by the second push-pull member 303. When the electrical signals fed back by the first sensor 400 and the third sensor 600 reach their maximum values, the maximum tensile force fed back by the first sensor 400 and the third sensor 600 is read by the control console 1200.

[0110] The data verification step determines whether the measured value of the first sensor 400 is equal to the measured value of the second sensor 500 and / or the third sensor 600. If so, the first sensor 400 is qualified; otherwise, it is unqualified.

[0111] It should be noted that the second sensor 500 and the third sensor 600 are used to detect the same value as the first sensor 400. The equality of the measured values ​​is used to verify whether the first sensor 400 is qualified. Therefore, the accuracy of the second sensor 500 and the third sensor 600 should be ensured. To ensure the accuracy of the first sensor 400, the maximum thrust value measured by the second sensor 500 and the maximum tension value measured by the third sensor 600 are usually compared with the maximum thrust value and maximum tension value measured by the first sensor 400, respectively. Only when they are equal is the first sensor 400 considered qualified. However, in special cases, it is only necessary for the first sensor 400 to accurately detect either thrust or tension. Therefore, it is only necessary to determine whether the maximum thrust value measured by the second sensor 500 is equal to the maximum thrust value measured by the first sensor 400, or whether the maximum tension value measured by the third sensor 600 is equal to the maximum tension value measured by the first sensor 400, in which case the first sensor 400 is considered qualified.

[0112] During the actual testing process, the testing personnel installed the power unit 1300 on the mounting bracket 1000 and electrically connected it to the control console 1200. The actuating end of the power unit 1300 passed through the mounting slot 1001 and connected to the third connector 900. The second sensor 500 and the third sensor 600 were installed in the first space and the second space, respectively. The power unit 1300 was turned on by the control console 1200, so that the power unit 1300 pushed or pulled the third connector 900 to move, thereby transmitting power sequentially to the first sensor 400, the second connector 700, the first connector 304 and the first push-pull member 302. The first push-pull member 302 moved closer to or away from the fixed member 201, and the corresponding second push-pull member 303 moved away from or closer to the fixed member 201.

[0113] When the first push-pull member 302 pushes the second sensor 500 to be close to the side wall of the fixing member 201, the support device 200 and the sliding device 300 no longer move relative to each other. The thrust received by the first sensor 400 and the second sensor 500 reaches its maximum value. The maximum thrust detected by the first sensor 400 and the second sensor 500 can be obtained by reading the thrust received by the first sensor 400 and the second sensor 500 at this time through the control console 1200. By comparing the two measured values, if they are equal, the first sensor 400 is qualified; if they are not equal, the first sensor 400 is unqualified.

[0114] When the second push-pull member 303 pulls the third sensor 600 close to the side wall of the fixing member 201, the support device 200 and the sliding device 300 no longer move relative to each other. The tension force on the first sensor 400 and the third sensor 600 reaches its maximum value. The maximum value of the tension force detected by the first sensor 400 and the third sensor 600 can be obtained by reading the tension force on the first sensor 400 and the third sensor 600 at this time through the control console 1200. By comparing the two measured values, if they are equal, the first sensor 400 is qualified; if they are not equal, the first sensor 400 is unqualified.

[0115] In summary, the push-pull force detection system and method provided in this application simplify the detection steps. Push or pull force can be detected simply by connecting the power unit 1300 to the first sensor 400. The first sensor 400 can be calibrated without frequent disassembly and reassembly.
