[0011] Compared with the prior art, the present utility model has the following beneficial effects:

[0012] 1. For this sensor diaphragm positioning device, by the controller emitting a signal, the motor can be started to make the rotating shaft rotate, so that the connecting suction cup can drive the moving plate to slide up and down on the outer wall of the sliding rod, enabling the lower pressing plate to move up and down on the inner wall of the diaphragm placement groove, so that the lower pressing plate can press and position the sensor diaphragm to ensure that the sensor diaphragm remains in a fixed position during the measurement process, preventing the diaphragm from generating displacement when subjected to external forces or vibrations, which may affect the accuracy of the measurement results.

[0013] 2. For this sensor diaphragm positioning device, after the positioning of the sensor diaphragm is completed, the lower pressing plate will stop sliding due to the positioning component. At this time, the reset spring will undergo elastic deformation to make the lower pressing plate bounce upward, so that the device can realize the repeated positioning of the diaphragm, enabling the diaphragm to return to the same position every time during measurement, improving the consistency and repeatability of the measurement, and effectively reducing the error caused by non-matching, further improving the measurement accuracy.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1 - Figure 5 , a sensor diaphragm positioning device, including an automatic reset component 1. A diaphragm placement groove 2 is installed on the top of the automatic reset component 1. A slide bar 3 is arranged on the top of the automatic reset component 1. The top of the slide bar 3 is fixedly installed with a top plate 4 through a connecting bolt 7. A controller 5 is fixedly assembled on the top of the top plate 4. A positioning component 6 is arranged on the top of the top plate 4. A lower pressing plate 8 is installed at the bottom of the positioning component 6;

[0024] With the above structure, through the setting of the connecting bolt 7, the stability of the device can be ensured, so that the sensor diaphragm is evenly stressed during fixation, and the diaphragm deformation caused by excessive local pressure can be effectively avoided.

[0025] In a preferred implementation manner, the automatic reset component 1 includes a base 101. A bottom plate 103 is installed on the inner wall of the base 101 through a mounting bolt 102. A limit seat 104 is fixedly assembled on the top of the bottom plate 103. A return spring 105 is fixedly installed on the top of the limit seat 104;

[0026] In a preferred implementation manner, the number of the base 101, the mounting bolt 102, the limit seat 104 and the return spring 105 is four each. And the four bases 101, the mounting bolts 102, the limit seats 104 and the return springs 105 are evenly distributed at the upper and lower ends of the bottom plate 103. The top of the limit seat 104 is in contact with the bottom of the limit top seat 607. The diameter of the return spring 105 is smaller than the diameter of the limit seat 104;

[0027] Using the above structure, through the setting of the return spring 105 and the position characteristics of the installation of the return spring 105, it can be known that after the positioning work of the device is completed, the lower pressing plate 8 will stop sliding due to the positioning component 6. At this time, the return spring 105 will undergo elastic deformation, enabling the lower pressing plate 8 to bounce upward, thus achieving the result of automatic reset.

[0028] In a preferred embodiment, the positioning component 6 includes a motor 601. The power output shaft of the motor 601 is fixedly assembled with a rotating shaft 602. A limiting plate 603 is sleeved and installed on the outer wall of the rotating shaft 602 through a fixing bolt 604.

[0029] In a preferred embodiment, one end of a connecting suction cup 605 is fixedly assembled at the bottom of the rotating shaft 602. A moving plate 606 is fixedly installed at the bottom of the connecting suction cup 605. A limiting top seat 607 is fixedly installed at the bottom of the moving plate 606. A circular hole 608 is formed at the top of the moving plate 606.

[0030] In a preferred embodiment, the motor 601 is electrically connected to the controller 5. The diameter of the circular hole 608 is adapted to the diameter of the sliding rod 3. The limiting plate 603 is fixedly installed at the top of the top plate 4 through the fixing bolt 604. The limiting top seat 607 is sleeved on the outer wall of the sliding rod 3.

[0031] Using the above structure, by the controller 5 emitting a signal, the motor 601 can be started. At this time, the rotating shaft 602 can rotate inside the limiting plate 603, so that the connecting suction cup 605 can drive the moving plate 606 to slide up and down on the outer wall of the sliding rod 3, enabling the lower pressing plate 8 to move up and down inside the diaphragm placement groove 2, so that the lower pressing plate 8 can press and position the sensor diaphragm, effectively ensuring that the sensor diaphragm maintains a fixed position during the measurement process and reducing the measurement error caused by the movement of the diaphragm.

[0032] Working principle: When using this device, first place the sensor diaphragm to be positioned on the inner wall of the diaphragm placement groove 2, and make the controller 5 emit a signal, which can start the motor 601. At this time, the rotating shaft 602 can rotate on the inner wall of the limit plate 603, so that the connecting suction cup 605 can drive the moving plate 606 to slide up and down on the outer wall of the sliding rod 3, so that the lower pressing plate 8 can move up and down on the inner wall of the diaphragm placement groove 2, so that the lower pressing plate 8 can press and position the sensor diaphragm, thus effectively ensuring that the sensor diaphragm remains fixed during the measurement process. And after the positioning of the sensor diaphragm is completed, the lower pressing plate 8 will stop sliding due to the positioning component 6. At this time, the return spring 105 will undergo elastic deformation, so that the lower pressing plate 8 can bounce up, so that the device can realize the repeated positioning of the diaphragm, so that the diaphragm can return to the same position every time it is measured, so that it is convenient for the device to complete the positioning work of the sensor diaphragm.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
