TECHNICAL FIELD
[0001] The utility model relates to sensor stroke test technical field especially relates to a stroke sensor stroke testing device. BACKGROUND
[0002] In the field of industrial production and equipment manufacturing, as a key component for precise measurement of displacement and stroke, the performance of stroke sensor directly affects the operation accuracy and reliability of equipment. A stroke sensor stroke testing device emerges as the times require. The device aims to provide an efficient and accurate performance testing environment for stroke sensors. In automobile manufacturing, stroke sensors that control door opening and closing, seat adjustment, and other functions need to be strictly tested. On the automated production line, sensors used for positioning the action stroke of mechanical arms also need to be calibrated with such devices to ensure smooth production flow. The device plays an indispensable role in many industrial processes.
[0003] In the prior art, stroke sensor stroke testing devices mostly use simple mechanical structures. Commonly, a fixed support is used to fix the stroke sensor, and a movable contact is manually operated to simulate the displacement under actual working conditions. Meanwhile, a simple dial or scale is used to read the stroke data. The technical principle is based on simple mechanical transmission and visual measurement. The operator manually pushes the contact, observes the change of the sensor output signal, and determines the stroke value by referring to the dial. In order to move the contact, some devices use screw nut transmission. Rotating the screw rod drives the nut and the connected contact to move linearly, thereby testing the performance of the stroke sensor under different displacements.
[0004] However, this traditional testing device has significant drawbacks. On the one hand, when fixing the stroke sensor, due to the lack of convenient and efficient fixing structure, it often takes a lot of time to adjust the sensor position and ensure its stability, resulting in extremely low testing efficiency. On the other hand, manually moving the contact and reading data through the dial is greatly affected by human factors, making it difficult to ensure measurement accuracy. When facing high-precision stroke sensor testing requirements, it cannot provide reliable and accurate test results. In addition, the traditional device can usually only adapt to stroke sensors of specific length specifications, making it difficult to flexibly cope with testing of different size products, greatly limiting its application range and practicality. Therefore, a stroke sensor stroke testing device is proposed to solve the above problems. UTILITY MODEL CONTENT

[0033] The test assembly comprises a connecting plate 8 made of stainless steel, which can stably slide on the outer wall of the mounting seat 1 through cooperation with the I-shaped sliding block 17, and plays a role of connecting and fixing the components such as the fixed plate 10 and the bearing plate 9. The connecting plate 8 is slidably connected to the outer wall of the mounting seat 1, and the outer wall of one side of the connecting plate 8 is fixedly connected with the fixed plate 10 made of carbon steel and having high hardness, which is used for fixing the triangular seat 11 and providing a stable installation basis for the rotating arm 12 and other components. The outer wall of the other side of the connecting plate 8 is fixedly connected with the bearing plate 9 made of engineering plastic and having a smooth surface and certain toughness, which is used for bearing the stroke sensing column 7 and keeping it stable during the test. The top of the fixed plate 10 is fixedly connected with the triangular seat 11 made of a triangular iron block of metal material and having a stable structure. The outer wall of the triangular seat 11 is rotatably connected with the rotating arm 12, which can rotate around the rotating shaft of the outer wall of the triangular seat 11. The top of the rotating arm 12 is fixedly connected with the pull handle 28 made of a metal rod wrapped with rubber, which provides strength and increases the comfort and friction force of holding, so as to facilitate the staff to rotate the rotating arm 12 by applying force. The inner top of the triangular seat 11 is rotatably connected with the movable arm 14, which can rotate at the rotating connection position of the inner top of the triangular seat 11. The middle position of the inner wall of the rotating arm 12 is rotatably connected with the connecting arm 13, which plays a role of connecting the rotating arm 12 and the movable arm 14, so that the rotation of the rotating arm 12 can drive the movable arm 14 to move. The other end of the connecting arm 13 is rotatably connected to the middle position of the outer wall of the movable arm 14. One end of the movable arm 14 is slidably connected with the connecting column 15, which is adjusted in height by sliding up and down in the groove at one end of the movable arm 14 through a nut, so as to adapt to the stroke sensing column 7 of different thicknesses. The bottom of the connecting column 15 is fixedly connected with the limiting block 16 made of rubber and having good friction and buffering performance, which is used for pressing the stroke sensing column 7 to prevent it from moving during the test. The stroke sensing column 7 is arranged between the limiting block 16 and the outer wall of the bearing plate 9. The outer wall of the stroke sensing column 7 is slidably connected with the magnetic ring 25, which generates a magnetic field and cooperates with the stroke sensing column 7 to detect the stroke. The outer wall of the magnetic ring 25 is provided with the magnetic ring fixing block 6 made of metal material, which is used for fixing the magnetic ring 25 to enable it to smoothly slide on the outer wall of the stroke sensing column 7. The bottom of the magnetic ring fixing block 6 is provided with the linear guide rail 5 made of metal material and having a high-precision surface, which is fixedly arranged on the inner wall of the guide groove 2 through bolts to provide stable linear guidance for the movement of the magnetic ring 25. The bottom of the linear guide rail 5 is slidably connected to the inner wall of the guide groove 2. The outer wall of one side of the magnetic ring fixing block 6 is fixedly connected with the handle 27 made of plastic material and convenient for the staff to hold, which can drive the magnetic ring 25 and related components to move. The outer wall of the other side of the magnetic ring fixing block 6 is fixedly connected with the pointer 26 made of a metal sheet and used for indicating the stroke value. The side wall of the pointer 26 is provided with the steel ruler 4.The steel plate ruler 4 is made of stainless steel material, and the scale is clear and accurate, which is used for reading the stroke data in cooperation with the pointer 26. The bottom of the steel plate ruler 4 is slidingly connected to the inner wall of the guide groove 2, which is consistent with the linear guide rail 5, and is fixed to the inner wall of the guide groove 2 by bolts. The left and right sides of the mounting seat 1 are slidingly connected with the fixed angle blocks 3 made of metal material, which are used for fixing the mounting seat 1 on the workbench or other installation positions. The side walls of the fixed angle blocks 3 are also fixed to the inner wall of the guide groove 2 by bolts.
[0034] Specifically, when using the stroke sensor stroke test device, first, the work staff places the stroke sensor column 7 at both ends on the surface of the bearing plate 9 stably, and then holds the pull handle 28 and applies force upward along the circumferential direction of the outer wall of the triangular seat 11 as the center of the rotating shaft. The pull handle 28 drives the rotating arm 12 to rotate clockwise around the rotating shaft of the outer wall of the triangular seat 11. With the rotation of the rotating arm 12, the connecting arm 13 inside it drives the movable arm 14 to rotate as well. During the rotation of the rotating arm 12, the rotating connection point between the middle position inside the rotating arm 12 and the connecting arm 13 is displaced. Since the other end of the connecting arm 13 is rotationally connected with the middle position of the outer wall of the movable arm 14, the connecting arm 13 transmits the rotation of the rotating arm 12 to the movable arm 14, so that the movable arm 14 rotates clockwise around the rotating connection at the top inside the triangular seat 11. When the movable arm 14 rotates to the horizontal position, the rotating arm 12 and the connecting arm 13 are in a vertical state at this time. The movable arm 14 drives the connecting column 15 at one end and the limiting block 16 at the bottom to press against the outer wall of the stroke sensor column 7. The connecting column 15 moves downward with the rotation of the movable arm 14, and finally the limiting block 16 contacts and applies pressure to the outer wall of the stroke sensor column 7, thereby completing the fixation of the stroke sensor column 7. After the stroke sensor column 7 is fixed, the magnetic ring 25 on the outer wall of the stroke sensor column 7 is fixed inside the magnetic ring fixing block 6. The work staff manually installs the magnetic ring 25 inside the magnetic ring fixing block 6. The work staff holds the handle 27 and pushes the handle 27 back and forth along the length direction of the linear guide rail 5. The handle 27 drives the bottom of the magnetic ring fixing block 6 to slide linearly along the surface of the linear guide rail 5, and also drives the magnetic ring fixing block 6 and the magnetic ring 25 connected thereto to move. The magnetic ring 25 slides back and forth along the outer wall of the stroke sensor column 7. Through the cooperation of the pointer 26 and the steel plate ruler 4, the stroke detected by the stroke sensor can be read. During the movement of the magnetic ring 25, the pointer 26 moves synchronously with the magnetic ring 25. The pointer 26 moves across the side wall of the steel plate ruler 4. The work staff observes the scale value corresponding to the pointer 26 on the steel plate ruler 4, thereby achieving the effect of quickly and accurately testing whether the stroke of the stroke sensor is accurate.
[0035] Referring to Figure 3The bottom of the side wall of the connecting plate 8 is fixedly connected with an I-shaped sliding block 17, the I-shaped sliding block 17 is made of high-strength aluminum alloy material, and the I-shaped sliding block 17 is matched with the guide groove 2 to provide stable support and guidance for the sliding of the connecting plate 8 on the mounting seat 1, the outer wall of the I-shaped sliding block 17 is slidably connected with the inner wall of the guide groove 2, the I-shaped sliding block 17 can smoothly slide in the guide groove 2, the inner wall of the I-shaped sliding block 17 is provided with a sliding groove 18, the sliding groove 18 provides a sliding space for a sliding column 19, the sliding groove 18 is slidably connected with the symmetric sliding columns 19, the sliding columns 19 are made of carbon steel material, the sliding columns 19 are connected with the movable plate 20 and transmit force, so that the movable plate 20 can be driven to move by the sliding columns 19, one end of the sliding column 19 is fixedly connected with the movable plate 20, the movable plate 20 is made of stainless steel material, the movable plate 20 is matched with the rubber sheet 21 and the inner wall of the guide groove 2 to generate friction force to fix the position of the connecting plate 8, the outer wall of the movable plate 20 is fixedly connected with a plurality of rubber sheets 21, the rubber sheets 21 are made of rubber material and have good elasticity and friction force, the rubber sheets 21 are arranged in an array, the contact area with the inner wall of the guide groove 2 can be increased, and the fixing effect is improved, the outer wall of the I-shaped sliding block 17 is provided with a rotating column 24, a plurality of flat pieces are fixed on the outer wall of the rotating column 24, the surface of the flat piece is treated to prevent slipping, and the rotating column 24 is rotated by the staff, the rotating column 24 is matched with the threaded column 22 to realize displacement, the threaded column 22 is made of metal material and is provided with threads on the surface, the threaded column 22 is matched with the threads in the I-shaped sliding block 17 to realize displacement, the threaded column 22 is connected with the rotating column 24, the threaded column 22 is fixedly connected with a fixed ball 23 at one end, the surface of the fixed ball 23 is smooth, the fixed ball 23 is matched with the sliding column 19 to generate displacement, and the threaded column 22 is slidably connected in the I-shaped sliding block 17;
[0036] Specifically, when the travel sensing column 7 of different lengths needs to be tested, the worker holds the rotating column 24 by hand and applies a torque force in the counterclockwise direction to make the rotating column 24 rotate counterclockwise around its central axis. The rotation of the rotating column 24 drives the threaded column 22 to rotate counterclockwise as well. The rotation of the rotating column 24 is directly transmitted to the threaded column 22, which starts to rotate under the action of the threads inside the I-shaped sliding block 17. Due to the cooperation between the threaded column 22 and the threads inside the I-shaped sliding block 17, when rotating counterclockwise, the threaded column 22 moves linearly outward along the helical direction of the threads. The displacement of the threaded column 22 drives the fixed ball 23 at the bottom of the threaded column 22 to move as well. As the fixed ball 23 moves outward, the contact between the fixed ball 23 and the bottom of the sliding column 19 gradually separates, and the extrusion force on the bottom of the sliding column 19 disappears, so that the sliding column 19 becomes loose. After losing the extrusion of the fixed ball 23, the sliding column 19 can freely slide in the sliding groove 18. After the sliding column 19 becomes loose, the movable plate 20 and the rubber sheet 21 fixedly connected to the sliding column 19 are no longer subjected to the outward pushing force, so they no longer extrude the inner wall of the guide groove 2. At this time, the worker can hold the connecting plate 8 by hand and push or pull the connecting plate 8 along the direction of the guide groove 2 to make it slide on the mounting seat 1. When the position is adjusted, the worker only needs to hold the rotating column 24 again and apply a torque force in the clockwise direction to make the rotating column 24 rotate clockwise around its central axis, which can promote the movable plate 20 to extrude the inner wall of the guide groove 2 again, so as to complete the fixation of the position of the connecting plate 8. Through the frictional force between the rubber sheet 21 and the inner wall of the guide groove 2, the connecting plate 8 is fixed at the adjusted position, thereby achieving the effect of quickly adjusting and fixing the position of the assembly to adapt to the testing requirements of the travel sensing column 7 of different lengths.
[0037] Working principle: when using the stroke sensor stroke test device, first, the two ends of the stroke sensor column 7 are placed above the bearing plate 9, then the staff turns the rotating arm 12 upward by pulling the handle 28, with the rotation of the rotating arm 12, the connecting arm 13 in it drives the movable arm 14 to rotate, when the movable arm 14 rotates to the horizontal position, the rotating arm 12 and the connecting arm 13 are in the vertical state at this time, the movable arm 14 drives the connecting column 15 at one end and the limiting block 16 at the bottom to press the outer wall of the stroke sensor column 7, thereby completing the fixation of the stroke sensor column 7, when the stroke sensor column 7 is fixed, the magnetic ring 25 on the outer wall of the stroke sensor column 7 is fixed in the magnetic ring fixed block 6, the staff holds the handle 27 to drive the magnetic ring fixed block 6 at the bottom to reciprocate on the outer wall of the linear guide rail 5, at the same time, the magnetic ring 25 on the outer wall of the stroke sensor column 7 is also driven to slide, through the cooperation of the pointer 26 and the steel ruler 4, the stroke of the stroke sensor detection can be read, thereby achieving the effect of quickly and accurately testing whether the stroke of the stroke sensor is accurate, when the stroke sensor column 7 of different lengths needs to be tested, the staff can rotate the rotating column 24 on the outer wall of the connecting plate 8 counterclockwise, the rotation of the rotating column 24 drives the threaded column 22 to rotate counterclockwise, under the action of the screw, the threaded column 22 gradually displaces outward, the displacement of the threaded column 22 drives the fixed ball 23 at the bottom to displace, the displacement of the fixed ball 23 makes the outer wall no longer extrude the bottom of the sliding column 19 on the upper and lower sides, so that the sliding column 19 becomes loose, further promoting the movable plate 20 together with the rubber sheet 21 no longer extruding the inner wall of the guide groove 2, at this time, the staff can move the connecting plate 8, when the position is adjusted, only the rotating column 24 needs to be rotated clockwise, so that the movable plate 20 can extrude the inner wall of the guide groove 2 again, thereby completing the fixation of the position of the connecting plate 8, thereby achieving the effect of quickly adjusting the position of the fixing assembly to adapt to the test requirements of stroke sensor columns 7 of different lengths.
