Description

Technical Field

[0001] The invention belongs to the technical field of industrial automation testing and measuring, and in particular relates to an intelligent self-testing device for a tuning fork. Background Art

[0002] The tuning fork multi-station test bench is an advanced device that integrates multiple independent test stations and is specially used to test tuning fork level meters or other similar sensors. It combines the essence of industrial automation and test and measurement technology. Each station is equipped with high-performance test instruments and precise control systems, which can automatically complete the test process. During the test, the equipment can capture and record the test data in real time, and analyze it in depth to ensure the accuracy and reliability of the test results. The emergence of the tuning fork multi-station test bench not only improves the test efficiency, but also reduces manual intervention, providing strong support for the quality control of industrial automation production lines. The traditional tuning fork multi-station test bench has shortcomings in terms of ease of operation and intelligence. Its operation interface may not be intuitive enough, so that users need to spend a lot of time to familiarize themselves with and master the operation methods. At the same time, the parameter setting and calibration steps during the test process may also be relatively complicated, which increases the difficulty of user operation. In addition, the traditional test bench has a low degree of intelligence in data recording, analysis and processing, and usually requires users to manually process and analyze data, which not only increases the workload of users, but also may affect the accuracy and efficiency of the test. In addition, the application scope of traditional test benches is limited. They may only be applicable to specific types of tuning fork level meters or sensors. They may not be able to test other types of sensors or the test results may be poor. At the same time, with the continuous development of industrial automation technology, new test requirements and test methods are constantly emerging. Traditional test benches may have limitations in scalability and flexibility, and it is difficult to meet the development needs of future testing technology. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] like Figures 1 to 8 As shown, an embodiment of the present invention provides an intelligent self-test device for a tuning fork, comprising a fixed bracket 1, a guide rail 3 is fixedly installed on the top of the fixed bracket 1, a positioning rod 12 is fixedly installed inside the guide rail 3, and one end of the positioning rod 12 passes through the inside of the guide rail 3, a cylinder 4 is fixedly installed on the top of the positioning rod 12, a slider 13 is fixedly installed on the outer surface of the positioning rod 12, a placement block 19 is fixedly installed on the outer side of the slider 13, an upper shelf plate 14 is fixedly installed on the top of the two placement blocks 19, a positioning hole 15 is opened inside the upper shelf plate 14, and a lifting component is fixedly installed on the top of the fixed bracket 1.

[0018] The staff placed the tuning fork to be tested inside the lifting assembly, and then started the cylinder 14 to drive the slider 2 13 to slide down smoothly along the positioning rod 2 12, and simultaneously drive the placement block 2 19 and the upper shelf plate 14 to descend. When the upper shelf plate 14 contacts the top of the tuning fork, the positioning hole 2 15 inside it contacts the tuning fork through electricity. At this time, the upper shelf plate 14 and the lifting assembly descend synchronously. During the detection process, the system switches the high and low positions of the PNP and NPN values ​​to comprehensively and accurately evaluate the performance of the tuning fork. If the tuning fork contacts the material, the system will immediately alarm; otherwise, there is no abnormality. After the detection is completed, the system displays the data current status to achieve a comprehensive detection of the tuning fork.

[0019] The tuning fork to be tested is placed inside the lifting assembly, and then the cylinder 14 is started to drive the slider 2 13 to slide smoothly down along the positioning rod 2 12, and simultaneously drive the placement block 2 19 and the upper shelf plate 14 to descend. When the upper shelf plate 14 contacts the top of the tuning fork, the positioning hole 2 15 inside it is electrically in contact with the tuning fork. At this time, the upper shelf plate 14 and the lifting assembly descend synchronously. Compared with the traditional test bench, the test bench is driven by the cylinder to achieve a smooth descent, and the upper shelf plate and the tuning fork are electrically in contact and descend synchronously. This process is not only efficient but also accurate. During the detection process, the system flexibly switches the high and low positions of the PNP and NPN values ​​to comprehensively evaluate the performance of the tuning fork and ensure the comprehensiveness of the detection. Once the tuning fork contacts the material, the system immediately alarms to effectively prevent potential problems. After the detection is completed, the system intuitively displays the data current status, which is convenient for quickly judging the tuning fork status. This not only improves the detection efficiency, but also enhances the accuracy of the detection, provides a reliable guarantee for the subsequent maintenance and use of the tuning fork, and ensures its stability and reliability in application.

[0020] The lifting assembly is fixedly mounted on the top of the fixed bracket 1, and the lifting assembly includes a guide rail 25 fixedly mounted on the top of the fixed bracket 1, a positioning rod 7 is fixedly mounted inside the guide rail 25, and one end of the positioning rod 7 passes through the inside of the guide rail 25, and a cylinder 26 is fixedly mounted on one end of the positioning rod 7; A slider 8 is fixedly installed on the outer surface of the positioning rod 7, a placement block 9 is fixedly installed on the inner side of the slider 8, a lower bracket 10 is fixedly installed on the top of the two placement blocks 9, and a positioning hole 11 is opened inside the lower bracket 10.

[0021] The staff puts the tuning fork into the positioning hole 11 and supports the tuning fork through the lower bracket 10. Now, the cylinder 26 is turned on to push the slider 8 to slowly descend on the outer surface of the positioning rod 7, and then the slider 8 drives the placement block 9 to descend synchronously, and then the placement block 9 drives the lower bracket 10 to descend synchronously, and then the lower bracket 10 drives the tuning fork to descend, thereby completing the descent of the tuning fork.

[0022] Put the tuning fork into the positioning hole 11, support the tuning fork through the lower bracket 10, now turn on the cylinder 26, push the slider 8 to slowly descend on the outer surface of the positioning rod 7 through the cylinder 26, and then drive the placement block 9 and the lower bracket 10 to descend synchronously through the slider 8, and then drive the tuning fork to descend through the lower bracket 10. Compared with the traditional test bench, the test bench is convenient for driving the slider 8, the placement block 9 and the lower bracket 10 to descend through the cooperation between the cylinder 26 and the slider 8, and then drives the tuning fork to descend through the slider 8, the placement block 9 and the lower bracket 10, which effectively avoids the vibration and collision of the tuning fork caused by rapid movement, protects the precise structure and surface coating of the tuning fork, and prolongs its service life. At the same time, the slow descent ensures the stability of the tuning fork when it reaches the test position, improves the accuracy of the test, and in addition, this mechanism also enhances the safety of operation and reduces the risk of the tuning fork falling off or being damaged. The design of the tuning fork multi-station test bench combined with the slow descent ensures that each tuning fork is tested according to a predetermined procedure, optimizes the test process, and improves the test efficiency.

[0023] Among them, a fixed bracket 2 2 is fixedly installed on the top of the fixed bracket 1, and a display bracket 17 is fixedly installed on the top of the fixed bracket 2 2. A display screen 18 is embedded in the display bracket 17.

[0024] Through the cooperation between the upper shelf plate 14 and the lower bracket 10, the detection data is displayed on the display bracket 17 through the display screen 18, which is convenient for the staff to view the values ​​and adjust the tuning fork processing process.

[0025] The placement block 19 and the upper shelf plate 14 are both provided with threaded holes 20 , and bolts 16 are movably installed inside the threaded holes 20 .

[0026] By slowly screwing the bolt 16 into the threaded hole 20, the threaded hole 20 and the bolt 16 cooperate with each other, so as to facilitate the limiting and fixing of the upper shelf plate 14 and the placement block 2 19, and facilitate the shaking of the placement block 2 19 and the upper shelf plate 14 during use.

[0027] The positioning holes 11 are arranged in a linear array inside the lower bracket 10 , and the positioning holes 11 are in a hexagonal shape.

[0028] Since the positioning hole 11 is in a hexagonal shape on the lower bracket 10 and the positioning hole 11 is in a linear array shape, it is convenient to put the tuning fork into the positioning hole 11, and the hexagonal shape is convenient for limiting and fixing the positioning hole 11, thereby improving the stability of the tuning fork detection data.

[0029] Among them, a fixing block 21 is fixedly installed inside the fixing bracket 1, and the fixing block 21 presents two shapes of the same size.

[0030] Since the fixing block 21 presents two shapes of the same size inside the fixing bracket 1, it is convenient to provide stable support for the fixing bracket 1, ensure the stability of the fixing bracket 1 during use, reduce the shaking of the fixing bracket 1 during use, and improve the use efficiency of the fixing bracket 1.

[0031] Among them, guide rail 1 3 and guide rail 2 5 are grouped in pairs, and there are two groups at the top of fixed bracket 1.

[0032] Since guide rail 1 3 and guide rail 2 5 are grouped in pairs, there are two groups at the top of fixed bracket 1. Through the cooperation between guide rail 1 3 and guide rail 2 5, it is convenient to provide stable support for the lower bracket 10 and the upper shelf plate 14 during the up and down movement, and reduce the shaking of positioning hole 11 and the upper shelf plate 14 during the up and down movement.

[0033] The inner diameter of the positioning hole 11 is equal to the outer diameter of the tuning fork, and the inner part of the positioning hole 11 is designed to be smooth.

[0034] Since the interior of the positioning hole 11 adopts a smooth design and the diameter of the interior of the positioning hole 11 is equal to the outer diameter of the tuning fork, it is convenient to place the tuning fork into the interior of the positioning hole 11, thereby ensuring the stability of the tuning fork when placed in the interior of the positioning hole 11 and improving the detection efficiency of the tuning fork.

[0035] Working principle and usage process: The staff placed the tuning fork to be tested inside the lifting assembly, and then started the cylinder 14 to drive the slider 2 13 to slide down smoothly along the positioning rod 2 12, and simultaneously drive the placement block 2 19 and the upper shelf plate 14 to descend. When the upper shelf plate 14 contacts the top of the tuning fork, the positioning hole 2 15 inside it contacts the tuning fork through electricity. At this time, the upper shelf plate 14 and the lifting assembly descend synchronously. During the detection process, the system switches the high and low positions of the PNP and NPN values ​​to comprehensively and accurately evaluate the performance of the tuning fork. If the tuning fork contacts the material, the system will immediately alarm; otherwise, there is no abnormality. After the detection is completed, the system displays the data current status to achieve a comprehensive detection of the tuning fork.

[0036] The staff puts the tuning fork into the positioning hole 11 and supports the tuning fork through the lower bracket 10. Now, the cylinder 26 is turned on to push the slider 8 to slowly descend on the outer surface of the positioning rod 7, and then the slider 8 drives the placement block 9 to descend synchronously, and then the placement block 9 drives the lower bracket 10 to descend synchronously, and then the lower bracket 10 drives the tuning fork to descend, thereby completing the descent of the tuning fork.
