Description

Technical Field

[0001] This utility model relates to the field of pressure sensor detection technology, and in particular to a precision detection device for pressure sensor processing. Background Technology

[0002] Pressure sensors are among the most commonly used sensors in industrial practice, widely applied in various industrial automation environments, including water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemicals, oil wells, power, shipbuilding, machine tools, pipelines, and many other industries. A pressure sensor is a device that can sense pressure signals and convert them into usable electrical output signals according to certain rules.

[0003] Pressure sensors need to be fixed during testing, but after each sensor is tested, the next sensor needs to be reinstalled. The disassembly and reassembly process consumes a lot of time, thus reducing testing efficiency. Therefore, we propose an accuracy testing device for pressure sensor processing. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a precision detection device for pressure sensor processing.

[0005] This utility model is achieved using the following technical solution: a precision testing device for processing pressure sensors, including a testing platform, a mounting base fixedly connected to the top of the testing platform, a standard pressure sensor fixedly mounted on the top of the mounting base, a display screen on the top of the testing platform, a rotating assembly on the right side of the mounting base, multiple sets of fixing assemblies on the surface of the rotating assembly, a testing assembly on the top of the testing platform, and support columns fixedly connected to the four corners of the bottom of the testing platform.

[0006] The rotating assembly includes a hollow column, a driven gear is fixedly connected to the surface of the hollow column, a motor is provided at the left end of the hollow column, a driving gear is fixedly connected to the output end of the motor, a fixed seat is fixedly connected to the top of the hollow column, and a connector is fixedly connected to the top of the fixed seat.

[0007] The above technical solution allows the connector's wiring to pass through the cavity inside the hollow column and connect to the display screen. When the pressure sensor to be tested and the wire are connected to the connector, signal transmission between the pressure sensor to be tested and the display screen is realized. The motor drives the drive gear to rotate. Since the drive gear and the driven gear mesh with each other, the driven gear rotates and drives the hollow column to rotate, causing the pressure sensor to be tested on another fixed component to rotate to the bottom of the detection component, thus realizing continuous detection.

[0008] As a further improvement to the above solution, the surface of the hollow column is rotatably connected to the inner wall of the testing platform, the driven gear meshes with the driving gear, and the top of the motor is fixedly connected to the bottom of the testing platform.

[0009] The above technical solution uses a large driven gear and a small driving gear to reduce the rotational speed and prevent excessive speed from affecting the adjustment accuracy.

[0010] As a further improvement to the above solution, the fixing component includes an extension plate, a fixing clamp is fixedly connected to the top of the extension plate, a sliding groove is provided on the inner wall of the extension plate, a movable clamp is slidably connected to the inner wall of the sliding groove, and a threaded rod is threadedly connected to the inner wall of the extension plate.

[0011] Through the above technical solution, by rotating the threaded rod, which is threaded to the inner wall of the extension plate, the threaded rod will move into the sliding groove during rotation and push the movable clamping plate to move. Together with the fixed clamping plate, the pressure sensor to be tested is clamped and fixed, preventing it from moving during subsequent testing. Since there are multiple sets of fixing components, the pressure sensor to be tested can be fixed in advance.

[0012] As a further improvement to the above solution, one end of the extension plate is fixedly connected to the surface of the hollow column.

[0013] With the above technical solution, the extension plate and the mounting base are on the same horizontal line, so that the pressure plate can simultaneously contact the standard pressure sensor and the pressure sensor with detection.

[0014] As a further improvement to the above solution, one end of the threaded rod extends into the interior of the sliding groove and is rotatably connected to the extension plate.

[0015] The above technical solution uses a sliding groove to limit the movement of the movable clamping plate, ensuring its stability during movement.

[0016] As a further improvement to the above solution, the detection component includes a mounting frame, a cylinder is fixedly connected to the top of the mounting frame, the output end of the cylinder passes through the mounting frame and is fixedly connected to a pressure plate, and a guide rod is fixedly connected to the top of the pressure plate.

[0017] The above technical solution uses a cylinder to push a pressure plate downwards, which applies pressure to both the standard pressure sensor and the pressure sensor under test. Since the wires of the pressure sensor under test are connected to the connector, the signal can be transmitted to the display screen. By comparing the measured values ​​of the standard pressure sensor and the pressure sensor under test on the display screen, the accuracy of the pressure sensor under test can be determined.

[0018] As a further improvement to the above solution, the bottom of the mounting bracket is fixedly connected to the top of the testing platform, and the surface of the guide rod is slidably connected to the inner wall of the mounting bracket.

[0019] With the above technical solution, when the pressure plate moves, the guide rod will slide along the inner wall of the mounting bracket, avoiding deviation during the movement of the pressure plate, thereby ensuring the accuracy of the test.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This invention features a rotating assembly, specifically a motor that drives a drive gear to rotate. The drive gear meshes with the driven gear, causing the driven gear to rotate and rotate the hollow column. This causes the pressure sensor to be tested on another fixed assembly to rotate to the bottom of the detection assembly, enabling continuous detection and reducing the waiting time for disassembling and assembling the pressure sensor, thereby improving detection efficiency.

[0022] This invention uses a fixing component, specifically a rotating threaded rod. Because the threaded rod is threaded to the inner wall of the extension plate, the rotating threaded rod moves into the sliding groove and pushes the movable clamping plate to move. Together with the fixed clamping plate, the pressure sensor to be tested is clamped and fixed, preventing it from moving during subsequent testing and affecting the testing accuracy.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] Example:

[0032] Please combine Figure 1-5 This embodiment of a precision testing device for pressure sensor processing includes a testing platform 1, a mounting base 2 fixedly connected to the top of the testing platform 1, a standard pressure sensor 3 fixedly mounted on the top of the mounting base 2, a display screen 4 on the top of the testing platform 1, a rotating component 5 on the right side of the mounting base 2, multiple sets of fixing components 6 on the surface of the rotating component 5, a testing component 7 on the top of the testing platform 1, and support columns 8 fixedly connected to the four corners of the bottom of the testing platform 1.

[0033] The rotating assembly 5 includes a hollow column 501, with a driven gear 502 fixedly connected to the surface of the hollow column 501. A motor 504 is installed at the left end of the hollow column 501, and a driving gear 503 is fixedly connected to the output end of the motor 504. A fixed base 505 is fixedly connected to the top of the hollow column 501, and a connector 506 is fixedly connected to the top of the fixed base 505. When the motor 504 is started, it drives the driving gear 503 to rotate. Since the driving gear 503 and the driven gear 502 mesh with each other, the driven gear 502 rotates, causing the hollow column 501 to rotate. This causes the pressure sensor to be tested on another fixed assembly 6 to rotate to the bottom of the detection assembly 7, enabling continuous detection, reducing the waiting time for disassembling and assembling the pressure sensor to be tested, and thus improving detection efficiency.

[0034] The surface of the hollow column 501 is rotatably connected to the inner wall of the testing table 1, the driven gear 502 meshes with the driving gear 503, and the top of the motor 504 is fixedly connected to the bottom of the testing table 1.

[0035] The fixing assembly 6 includes an extension plate 601, with a fixing clamp 602 fixedly connected to the top of the extension plate 601. A sliding groove 603 is formed on the inner wall of the extension plate 601, and a movable clamp 604 is slidably connected to the inner wall of the sliding groove 603. A threaded rod 605 is threadedly connected to the inner wall of the extension plate 601. The pressure sensor to be tested is placed between the fixing clamp 602 and the movable clamp 604. By rotating the threaded rod 605, since the threaded rod 605 is threaded to the inner wall of the extension plate 601, the threaded rod 605 will move into the sliding groove 603 during rotation and push the movable clamp 604 to move. This, together with the fixing clamp 602, clamps and fixes the pressure sensor to be tested, preventing it from moving during subsequent testing and affecting the testing accuracy.

[0036] One end of the extension plate 601 is fixedly connected to the surface of the hollow column 501.

[0037] One end of the threaded rod 605 extends into the interior of the sliding groove 603 and is rotatably connected to the extension plate 601.

[0038] The detection assembly 7 includes a mounting bracket 701. A cylinder 702 is fixedly connected to the top of the mounting bracket 701. The output end of the cylinder 702 passes through the mounting bracket 701 and is fixedly connected to a pressure plate 703. A guide rod 704 is fixedly connected to the top of the pressure plate 703. When the cylinder 702 is activated, the output end of the cylinder 702 pushes the pressure plate 703 downward, applying pressure to the standard pressure sensor 3 and the pressure sensor under test through the pressure plate 703.

[0039] The bottom of the mounting bracket 701 is fixedly connected to the top of the testing table 1, and the surface of the guide rod 704 is slidably connected to the inner wall of the mounting bracket 701.

[0040] The implementation principle of the accuracy detection device for pressure sensor processing in this embodiment is as follows: During use, the pressure sensor to be tested is placed between the fixed clamping plate 602 and the movable clamping plate 604. By rotating the threaded rod 605, which is threaded to the inner wall of the extension plate 601, the threaded rod 605 moves into the sliding groove 603 and pushes the movable clamping plate 604 to move. This, in conjunction with the fixed clamping plate 602, clamps and fixes the pressure sensor to be tested, preventing movement during subsequent testing and ensuring accuracy. Then, the wires of the pressure sensor to be tested are connected to the connector 506. Next, the cylinder 702 is activated, and its output pushes the pressure plate 703 downwards. The pressure plate 703 applies pressure to the standard pressure sensor 3 and the pressure sensor to be tested. The standard pressure sensor 3 monitors the pressure in real time. The applied pressure value is transmitted and displayed on the display screen 4. Simultaneously, the pressure sensor under test also monitors the applied pressure value and transmits it to the display screen 4. By comparing the measured values ​​of the standard pressure sensor 3 and the pressure sensor under test on the display screen 4, the accuracy of the pressure sensor under test is determined to be qualified, thus completing the test. When the pressure sensor under test on one of the fixed components 6 has completed the test, the motor 504 is started. The motor 504 drives the drive gear 503 to rotate. Since the drive gear 503 and the driven gear 502 mesh with each other, the driven gear 502 rotates, causing the hollow column 501 to rotate, so that the pressure sensor under test on the other fixed component 6 rotates to the bottom of the detection component 7, realizing continuous detection, reducing the waiting time for disassembling and assembling the pressure sensor under test, and thus improving the detection efficiency.
