Description

Technical Field

[0001] This invention relates to the technical field of gate measuring instruments, specifically a dual-position difference ceramic piston rod gate measuring instrument. Background Technology

[0002] The ceramic piston rod gate measuring instrument is a high-precision instrument used to measure the opening of hydraulic and hydroelectric gates. It utilizes grooves on a ceramic piston rod and a magnetoresistive sensor array module to accurately measure the gate opening. Its working principle involves spraying ceramic onto a metal piston rod, and engraving annular grooves of equal width and depth but varying spacing on the ceramic layer. The arrangement of these grooves contains absolute position information. These grooves are installed at intervals between the cylinder and the ceramic piston rod. As the piston rod moves, the sensor array module detects the arrangement of the grooves on the piston rod, acquiring absolute coded position information. This absolute position information is obtained through a probe and electronically subdivided to obtain a high-precision measurement result. It is a high-precision, high-reliability measuring instrument widely used in various fields requiring precise displacement measurement.

[0003] Common dual-differential ceramic piston rod gate measuring instruments are often inconvenient to adjust during use. Different settings and adjustments may be required for different application scenarios, which greatly reduces the adaptability of the measuring instrument and limits its application in various environments. If the position or parameters of the measuring instrument cannot be easily adjusted, it may lead to inaccurate measurement results, affecting the normal operation and control effect of the system. At the same time, without a protective structure for the actuator, the actuator is exposed to the external environment and is easily contaminated by dust, impurities and other contaminants. These contaminants may enter the actuator, causing wear or jamming of mechanical parts, affecting measurement accuracy and equipment life, and bringing certain adverse effects to the user experience. To address these issues, we propose a dual-differential ceramic piston rod gate measuring instrument. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a dual-position difference ceramic piston rod gate measuring instrument, which offers advantages such as improved measurement accuracy, adaptability to different working conditions, and enhanced safety. The moving block is fitted onto the outer wall of the adjusting rod through a threaded hole, and the guide block is fitted onto the outer wall of the guide rod through a through hole, positioning the support frame on both sides of the upper end of the positioning adjusting frame. A control motor drives the adjusting rod to rotate inside the adjusting groove, causing the moving block to move on the outer wall of the adjusting rod, simultaneously driving the support frame to move in the opposite direction. The driver drives the rotating rod to rotate the measuring gear, enabling the measurement and monitoring of the gate opening. The instrument's position can be finely adjusted to ensure accurate measurement points, thereby improving measurement accuracy and allowing for flexible adaptation to different working environments. The application scope has been expanded by modifying the environment and measuring objects. The insertion block frame is inserted into the inner side of the insertion slot, and the positioning block is snapped into the inner side of the first positioning port, so that the protective cover is positioned outside the driver. This can prevent dust, oil and other contaminants from entering the driver, thereby ensuring the normal operation of the driver and extending its service life. At the same time, it can prevent external objects from accidentally contacting the moving parts of the driver, reducing the occurrence of safety accidents. The anti-slip pad on the outer wall of the insertion block frame can enhance the friction and make the engagement more secure. The heat dissipation mesh is snapped into the inner wall of the second positioning port and is positioned with the protective cover by the positioning frame and bolts.

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] like Figure 1-6 As shown, a dual-position difference ceramic piston rod gate measuring instrument includes a positioning adjustment frame 1. A control port 2 is provided in the middle of the upper end of the positioning adjustment frame 1. Adjustment grooves 3 are provided at both ends of the control port 2. A movable groove 4 is provided on one side of the upper end of the positioning adjustment frame 1. A control motor 5 is fixedly connected to the inner wall of the control port 2. An adjustment rod 6 is movably connected to the inner wall of the adjustment groove 3. A guide rod 7 is fixedly connected to the inner wall of the movable groove 4. Through the cooperation of the control motor 5 and the adjustment rod 6, the measuring instrument can be precisely adjusted. The guide rod 7 is fixed to the inner wall of the movable groove 4, which can ensure the linear movement of the piston rod during the measurement process, reduce deviation, and improve measurement accuracy.

[0025] Furthermore, the outer wall of the control motor 5 is fixedly connected to the inner wall of the control port 2, one end of the adjusting rod 6 passes through the inner wall of the adjusting groove 3 and is movably connected to both ends of the control motor 5, and both ends of the guide rod 7 are fixedly connected to the inner wall of the movable groove 4. The fixed connection between the outer wall of the control motor 5 and the inner wall of the control port 2 ensures that the motor will not shift or shake during operation, thus improving the stability of the system. The design of the adjusting rod 6, which passes through the inner wall of the adjusting groove 3 and is movably connected to both ends of the control motor 5, allows the movement of the adjusting rod 6 to be precisely controlled, thereby achieving precise adjustment of the position of related components. The guide rod 7 ensures that the movable components move along a predetermined path, preventing them from shifting or jamming during movement, further improving the stability and reliability of the system.

[0026] Furthermore, support frames 10 are movably connected to both sides of the upper end of the positioning adjustment frame 1. A moving block 8 is fixedly connected to the lower end of the support frame 10. A threaded hole 9 is opened on the inner wall of the moving block 8. A driver 11 and a protective cover 19 are positioned and installed on the upper part of the rear end of the support frame 10. The driver 11 is located inside the protective cover 19, which can prevent dust, oil and other contaminants from entering the driver, thereby ensuring the normal operation of the driver and extending its service life. At the same time, it can prevent external objects from accidentally contacting the moving parts of the driver and reduce the occurrence of safety accidents.

[0027] Furthermore, a rear support 14 is fixedly connected to the lower part of the rear end of the support frame 10, and a guide block 15 is fixedly connected to the lower end of the rear support 14. A through hole 16 is opened on the inner wall of the guide block 15. A rotating rod 12 is movably connected to the front end of the support frame 10, and a measuring gear 13 is fixedly connected to the front end of the rotating rod 12. An insertion groove 17 is opened on the inner wall of the rear end of the support frame 10. First positioning holes 18 are opened at both the upper and lower ends of the inner wall of the insertion groove 17. The lower end of the support frame 10 is fixedly connected to the upper end of the moving block 8. The moving block 8 is sleeved on the outer wall of the adjusting rod 6 through the threaded hole 9. This modular design allows the support frame to flexibly adjust its height and position to adapt to different usage needs.

[0028] Furthermore, an insertion block frame 20 is fixedly connected to one end of the protective cover 19. An anti-slip pad 21 is fixedly connected to the outer wall of the insertion block frame 20. Positioning blocks 22 are fixedly connected to both the upper and lower ends of the insertion block frame 20. A second positioning port 23 is opened at the upper end of the protective cover 19. A heat dissipation mesh 24 is positioned and installed on the inner wall of the second positioning port 23. An outer anti-slip pad 25 is fixedly connected to the outer wall of the heat dissipation mesh 24. A positioning frame 26 is fixedly connected to the upper end of the outer wall of the heat dissipation mesh 24. An anti-slip pad 21 is fixedly connected to the outer wall of the insertion block frame 20. This can increase the friction between the insertion block frame 20 and the contact surface, prevent the protective cover 19 from sliding during use, and thus improve stability. Positioning blocks 22 are fixedly connected to both the upper and lower ends of the insertion block frame 20. These positioning blocks can ensure the accurate installation of the protective cover 19. To improve the accuracy and reliability of installation, a second positioning port 23 is provided at the upper end of the protective cover 19. A heat dissipation mesh 24 is installed on the inner wall of the second positioning port 23. The heat dissipation mesh 24 can effectively promote air circulation inside the protective cover 19, increase heat dissipation, and prevent internal equipment from overheating. An outer anti-slip pad 25 is fixedly connected to the outer wall of the heat dissipation mesh 24, which can increase the friction between the heat dissipation mesh 24 and the protective cover 19, prevent the heat dissipation mesh 24 from loosening or falling off during use, and thus improve the installation stability of the heat dissipation mesh 24. A positioning frame 26 is fixedly connected to the upper end of the outer wall of the heat dissipation mesh 24. The positioning frame 26 can further fix the position of the heat dissipation mesh 24, ensure its stable installation inside the protective cover 19, and prevent the heat dissipation mesh 24 from shifting due to vibration or other external forces.

[0029] Furthermore, the lower end of the support frame 10 is fixedly connected to the upper end of the movable block 8. The movable block 8 is fitted onto the outer wall of the adjusting rod 6 through the threaded hole 9. One end of the driver 11 and the rear bracket 14 are both fixedly connected to the rear end of the support frame 10. The upper end of the guide block 15 is fixedly connected to the lower end of the rear bracket 14. The guide block 15 is fitted onto the outer wall of the guide rod 7 through the through hole 16. This fit ensures that the support frame 10 maintains linear motion during movement, preventing deviation and swaying, and improving overall stability. The movable block 8 is fitted onto the outer wall of the adjusting rod 6 through the threaded hole 9. This means that by rotating the adjusting rod 6, the up and down movement of the moving block 8 can be precisely controlled. This threaded transmission method can provide high precision and stability, and is suitable for application scenarios that require fine adjustment. The guide block 15 is sleeved on the outer wall of the guide rod 7 through the through hole 16. This guiding structure can ensure that the moving block 8 maintains linear motion when moving, preventing deviation or shaking, thereby improving the stability of the entire system. By rotating the adjusting rod 6, the position of the moving block 8 can be flexibly adjusted, and the position of the support frame 10 can be adjusted at the same time, thereby adapting to different working requirements and environmental conditions, and improving the adaptability and flexibility of the system.

[0030] Furthermore, one end of the rotating rod 12 penetrates the inner wall of the support frame 10 and is connected to the driver 11, while the other end of the rotating rod 12 is fixedly connected to the inner wall of the measuring gear 13. One end of the insertion block frame 20 is fixedly connected to one end of the protective cover 19, and one side of the anti-slip pad 21 is attached to the outer wall of the insertion block frame 20 with strong adhesive for positioning. The connection between one end of the rotating rod 12 and the driver 11 enables precise control of the rotating rod 12, thereby ensuring the accurate rotation of the measuring gear 13. This is crucial for equipment requiring high-precision measurement or operation. The fixed connection between the insertion block frame 20 and the protective cover 19 effectively protects the internal components from external environmental influences such as dust and moisture, extending the service life of the equipment. The anti-slip pad 21 is attached to the outer wall of the insertion block frame 20 with strong adhesive, increasing friction and preventing slippage during operation, thus improving the safety and convenience of operation.

[0031] Furthermore, the lower ends of the positioning blocks 22 are fixedly connected to the upper and lower ends of the insertion block frame 20. The protective cover 19 is positioned with the support frame 10 through the engagement of the insertion block frame 20 and the insertion slot 17, as well as the engagement of the positioning blocks 22 and the first positioning port 18. The cooperation of the insertion block frame 20 and the insertion slot 17, and the engagement of the positioning blocks 22 and the first positioning port 18, ensure the stability and firmness of the protective cover 19 on the support frame 10, preventing loosening or falling off during use. This engagement design makes the installation and removal of the protective cover 19 more convenient and quick. Operators can easily install the protective cover 19 onto the support frame 10, or quickly disassemble it when maintenance is required. The engagement of the positioning blocks 22 and the first positioning port 18 ensures the precise alignment of the protective cover 19 during installation, avoiding poor protection or affecting the normal operation of other components due to positional deviation. Through multi-point positioning and engagement, it can be ensured that the protective cover 19 fits tightly against the support frame 10, effectively preventing external objects from impacting the robot's head and protecting internal precision components.

[0032] Furthermore, one side of the outer anti-slip pad 25 is attached and positioned to the outer wall of the heat dissipation mesh 24 with strong adhesive. The inner wall of the positioning frame 26 is fixedly connected to the outer wall of the heat dissipation mesh 24. The heat dissipation mesh 24 is inserted into the inner side of the second positioning port 23 and positioned by the positioning frame 26 and the protective cover 19. The strong adhesive is used to attach and position the outer anti-slip pad 25 and the heat dissipation mesh 24, which can ensure a tight connection between the two and prevent displacement or detachment during use. The design of the heat dissipation mesh 24 promotes air circulation, thereby improving heat dissipation efficiency. Inserting it into the second positioning port 23 and positioning it by the positioning frame 26 and the protective cover 19 can ensure that the position of the heat dissipation mesh 24 is fixed and will not be displaced due to vibration or other external forces, thus ensuring the heat dissipation effect. Positioning by the positioning frame 26 and the protective cover 19 can simplify the installation process and make the heat dissipation mesh 24 and the outer anti-slip pad 25 easier to install and remove. This not only facilitates the initial installation but also makes subsequent maintenance and cleaning easier.

[0033] Working Principle: A dual-position difference ceramic piston rod gate measuring instrument, in use, the moving block 8 is sleeved on the outer wall of the adjusting rod 6 through the threaded hole 9, and the guide block 15 is sleeved on the outer wall of the guide rod 7 through the through hole 16, so that the support frame 10 is positioned on both sides of the upper end of the positioning adjusting frame 1. The control motor 5 drives the adjusting rod 6 to rotate inside the adjusting groove 3, so that the moving block 8 moves on the outer wall of the adjusting rod 6, and at the same time drives the support frame 10 to move in the opposite direction. The driver 11 drives the rotating rod 12 to drive the measuring gear 13 to rotate, which can measure and monitor the opening of the gate. The position of the measuring instrument can be finely adjusted to ensure the accuracy of the measurement point, thereby improving the measurement accuracy. It can flexibly adapt to different working environments and measurement objects, expanding its application range. Insert block frame 20 inserts... The positioning block 22 is inserted into the inner side of the insertion slot 17 and the first positioning port 18, so that the protective cover 19 is positioned outside the driver 11. This can prevent dust, oil and other contaminants from entering the driver, thereby ensuring the normal operation of the driver and extending its service life. At the same time, it can prevent external objects from accidentally contacting the moving parts of the driver and reduce the occurrence of safety accidents. The anti-slip pad 21 on the outer wall of the insertion block frame 20 can enhance the friction and make the engagement more secure. The heat dissipation mesh 24 is inserted into the inner wall of the second positioning port 23 and is positioned with the protective cover 19 by the positioning frame 26 and bolts. The outer anti-slip pad 25 on the outer wall of the heat dissipation mesh 24 can enhance the friction and enhance the anti-slip effect. The heat dissipation mesh 24 on the upper end of the protective cover 19 can enhance heat dissipation.
