In order to ensure the accuracy and air tightness of ultrasonic gas meter to meet the requirements, the manufacturer needs to strictly detect it before leaving the factory. The traditional manual detection is low in efficiency and time-consuming, which cannot meet the mass production demand, so it is of great practical significance to develop a high-efficiency detection platform to improve the test efficiency and accuracy. At present, for the factory detection of ultrasonic gas meter, the common method mainly depends on manual recording of detection results, which is not only low in efficiency, but also prone to errors.

Those skilled in the art can obtain other embodiments by combining the embodiments of the present application without creative labor, and these embodiments are also within the protection scope of the present application.

[0031] The present application has found that there are problems of complicated manual operation and easy errors in the current ultrasonic gas meter detection process.

The present application will be described in further detail below.

[0032] The ultrasonic gas meter detection platform provided by the embodiments of the present application comprises a detection platform base 1, a positioning block 2 arranged on the base, the positioning block 2 being used for positioning and placing an ultrasonic gas meter, a clamping device 3 arranged correspondingly on the positioning block 2, the clamping device 3 being used for clamping and fixing the ultrasonic gas meter, an air inlet and outlet connector 4, a sealing device 5 and a reading device 6, and the detection of the ultrasonic gas meter is performed after the ultrasonic gas meter is clamped.

[0033] The detection platform is provided with a plurality of clamping positions for placing the gas meter, the clamping device 3 is used for fixing the gas meter on the positioning block 2 of the clamping position, the air inlet and outlet connector 4 is arranged on the detection platform and is used for connecting the air inlet and outlet interfaces of the ultrasonic gas meter, and the air pipe connector is sealed by the sealing device 5 to ensure the air tightness, and the reading device 5 is used for automatically reading the display count of the gas meter, thereby achieving the purpose of improving the detection efficiency. Through the reasonable design of the clamping device and the sealing device, the effective fixing and sealing of the ultrasonic gas meter are achieved, thereby improving the operation efficiency and test accuracy of the detection platform.

[0034] Specifically, the clamping device 3 includes a clamping block 31 and a cylinder 32 for pushing the clamping block. The clamping block 31 is used to fix the gas meter on the clamping position. The cylinder drives the clamping block 31 to displace through the cylinder piston rod 321, so as to clamp the ultrasonic gas meter. The clamping block 31 is provided with a rubber pad 311 on the abutting surface with the ultrasonic gas meter, which increases the friction coefficient of the contact surface with the gas meter and provides a certain buffer force, thereby improving the stability of clamping. In addition, the clamping block 31 can also be covered with rubber or other high-friction coefficient materials to enhance the gripping force.

[0035] The clamping position is provided with an adjusting block 21 which is in contact with the bottom of the gas meter. The positioning protrusion can be fixed or designed to be adjustable in height. The latter allows the same equipment to be applicable to products of various specifications. The fixed type positioning protrusion is suitable for production lines of large quantities of single type products, while the adjustable type is more flexible and can meet diversified market demands.

[0036] The gas inlet and outlet connector 4 includes a gas inlet connector 41 and a gas outlet connector 42, which are correspondingly arranged on both sides of the clamping position and correspond to the gas inlet and outlet connectors of the placed ultrasonic gas meter. The gas inlet and outlet connector 4 is provided with a support frame 43 which is fixedly connected to the clamping block 31 and moves together with the clamping block. When the clamping block 31 moves to clamp the ultrasonic gas meter, the gas inlet and outlet connector moves to the position of the gas pipe connector of the ultrasonic gas meter.

[0037] The sealing device 5 includes a sealing cylinder 51, a sealing pad 52, a sealing air bag 53 and a gas pipe 54 for inflating the sealing air bag 53.

The sealing air bag 53 is inflated by the gas pump 54 connected by the gas pipe. After the sealing air bag 53 is inflated, the sealing cylinder 51 is inflated and filled, and the gas pipe connector of the ultrasonic gas meter is clamped and sealed. After the test is completed, the sealing air bag 53 is no longer inflated and pressurized, and the sealing air bag 53 shrinks after the air pressure is released, so as to separate the clamping and sealing of the gas pipe connector of the ultrasonic gas meter, which facilitates the separation of the gas inlet and outlet connector 4 and the gas pipe connector of the ultrasonic gas meter. By setting the sealing device 5, the clamping and sealing of the ultrasonic gas pipe during connection can reduce the resistance of the clamping block 31 during movement and ensure smooth movement.

[0038] The gas inlet and outlet joint 4 includes a gas inlet joint 41 for introducing gas into the gas meter and a gas outlet joint 42 for receiving the discharged gas. The gas tightness of the gas meter can be detected by comparing the amount of gas introduced and the amount of gas discharged. The data of the amount of gas introduced is used for testing the accuracy of the ultrasonic gas meter.

[0039] The implementation principle of the embodiment is that: through reasonable design of clamping devices and sealing devices, effective fixation and sealing of the ultrasonic gas meter are realized, so that the operation efficiency and test accuracy of the detection platform are improved. Compared with the traditional manual detection method, the operation intensity of the operator can be significantly reduced, and the error caused by human factors can be greatly reduced. In addition, through the integrated intelligent reading device, automatic reading and recording of the gas value are realized, the efficiency of counting and extracting is improved, and the automation level and reliability of the overall system are greatly enhanced. In summary, the detection platform is a major innovation and improvement of the current detection method, and represents a new development direction and technical path. The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, therefore: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
