[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-3 As shown, this utility model provides a technical solution: a Coriolis mass flow meter fitting measurement fixture, including a metering platform 1. The metering platform 1 is the basic support structure of the entire measurement fixture, providing a platform for the installation and operation of other components. A placement groove 2 is fixedly installed on the upper surface of the metering platform 1. The placement groove 2 is used to place the Coriolis mass flow meter fitting to be measured, serving as a positioning and initial fixation function to facilitate subsequent measurement operations. A fixing plate 3 is fixedly installed on the left side of the placement groove 2. The fixing plate 3 provides an installation benchmark and support for other components. A tensioning measuring device 4 is set on the left side of the fixing plate 3. The tensioning measuring device 4 is used for tensioning and measurement-related operations of the fitting. An electric push rod 5 is fixedly installed on the lower surface of the metering platform 1. The electric push rod 5 serves as a power source, providing power for subsequent pushing operations. A pushing vertical block 6 is fixedly installed at the output end of the electric push rod 5. When lever 5 is working, it drives the vertical push block 6 to move. A push rack plate 7 is fixedly installed on the upper surface of the push vertical block 6. The movement of the push vertical block 6 drives the push rack plate 7 to move. A fixed horizontal block 8 is fixedly installed on the upper surface of the metering platform 1. The fixed horizontal block 8 is used to install the rotating shaft 9. A rotatable rotating shaft 9 is set on the top of the fixed horizontal block 8. The rotating shaft 9 can rotate flexibly on the fixed horizontal block 8. A rotating gear 10 is fixedly installed on the outer end of the rotating shaft 9. When the rotating shaft 9 rotates, it drives the rotating gear 10 to rotate. The push rack plate 7 meshes with the rotating gear 10. The linear motion of the push rack plate 7 can be converted into the circular motion of the rotating gear 10. An arc-shaped pressing rod 11 is fixedly installed on the inner end of the rotating gear 10. The rotation of the rotating gear 10 drives the arc-shaped pressing rod 11 to swing. A pressing horizontal plate 12 is fixedly installed on the top of the arc-shaped pressing rod 11. The swing of the arc-shaped pressing rod 11 causes the pressing horizontal plate 12 to press and fix the pipe fitting.

[0022] The tension measuring device 4 includes a measuring horizontal plate 401 fixedly installed on the left side of the fixed vertical plate 3. The measuring horizontal plate 401 is the main load-bearing structure of the tension measuring device 4. A stabilizing horizontal plate 402 is fixedly installed on the left side of the measuring horizontal plate 401. The stabilizing horizontal plate 402 is used to enhance the stability of the entire device. A compression spring column 403 is fixedly installed on the right side of the stabilizing horizontal plate 402. The compression spring column 403 provides elastic force. A sliding horizontal frame 404 is fixedly installed on the right side of the compression spring column 403 and is slidably disposed on the outer surface of the measuring horizontal plate 401. The sliding horizontal frame 404 can slide on the measuring horizontal plate 401. A rotatable linkage rod 405 is provided on the right side of the sliding horizontal frame 404. The linkage rod 405 can realize the transmission of force and motion. A linkage bracket 406 is rotatably disposed on the right side of the linkage rod 405. The linkage bracket 406 further transmits motion. An arc-shaped compression plate 407 is fixedly installed on the right side of the linkage bracket 406. The arc-shaped compression plate 407 is used to compress and tension the pipe fitting.

[0023] Specifically, such as Figure 1 and Figure 2 As shown, a movable slider is fixedly installed inside the pushing vertical block 6, and a movable groove is provided on the upper surface of the measuring platform 1. The movable slider is slidably connected to the movable groove. This sliding connection method ensures the stability and accuracy of the pushing vertical block 6 during movement, enabling the pushing vertical block 6 to move smoothly along a predetermined direction, thereby driving components such as the pushing rack plate 7 to work accurately. There are two sets of pressing horizontal plates 12, and the inner surfaces of both sets of pressing horizontal plates 12 are provided with friction anti-slip textures. Setting two sets of pressing horizontal plates 12 can press and fix the pipe from different directions, improving the fixing effect, while the friction anti-slip textures can increase the friction between the pipe and the pipe, preventing the pipe from sliding during the measurement process and ensuring the accuracy of the measurement.

[0024] Specifically, such as Figure 3 As shown, a long strip-shaped through hole is provided on the left side of the fixed upright plate 3, and a movable horizontal column is fixedly installed on the right side of the linkage bracket 406. The movable horizontal column slides in the long strip-shaped through hole. This structural design allows the linkage bracket 406 to move along the direction of the long strip-shaped through hole, thereby driving the arc-shaped extrusion plate 407 to perform tensioning operation on the pipe, and ensuring the stability and accuracy of the movement. A sliding through hole is provided inside the sliding crossbar 404. The size of the sliding through hole is adapted to the size of the measuring crossbar 401, so that the sliding crossbar 404 can slide smoothly on the measuring crossbar 401, ensuring the normal operation of the tension measuring device 4.

[0025] The working principle of this utility model is as follows:

[0026] S1. Place the Coriolis mass flow meter fitting in the placement groove 2 and use the placement groove 2 to initially position the fitting.

[0027] S2. Then start the electric push rod 5. The output end of the electric push rod 5 drives the vertical block 6 to move. The vertical block 6 drives the rack plate 7 to mesh with the rotating gear 10, so that the rotating gear 10 drives the rotating shaft 9 to rotate. The rotating shaft 9 drives the arc-shaped pressing rod 11 and the pressing horizontal plate 12 to press and fix the pipe fitting, ensuring that the pipe fitting will not move in the horizontal direction during the measurement process.

[0028] S3. Under the action of its own elastic force, the compression spring column 403 drives the sliding crossbeam 404 and the linkage rod 405 to push the linkage bracket 406 and the arc-shaped compression plate 407 to move outward to measure the inner diameter of the Coriolis mass flow meter fitting. The measurement result is obtained according to the scale on the surface of the measuring crossbeam 401. At the same time, the length of the Coriolis mass flow meter fitting is measured using tools such as a ruler.

[0029] In summary, this Coriolis mass flow meter fitting measuring fixture uses an electric push rod 5 and a pusher block 6 to drive a pusher rack plate 7 to mesh with a rotating gear 10, which in turn drives an arc-shaped pressing rod 11 and a pressing horizontal plate 12 to clamp and fix the Coriolis mass flow meter fitting. This makes the fixing operation simpler and more convenient. The entire process does not require multiple people to cooperate and can be operated by a single person. This simplifies the measurement operation process, improves measurement efficiency, and helps to perform Coriolis mass flow meter fitting measurements more efficiently.

[0030] This Coriolis mass flow meter fitting measuring fixture uses a compression spring column 403 to drive a sliding crossbar 404 and a linkage rod 405 to move a linkage bracket 406 and an arc-shaped compression plate 407 outwards to measure the inner diameter of the Coriolis mass flow meter fitting. It can adaptively adjust according to different sizes and shapes of the fitting, ensuring that the fitting is always in a suitable tension state during the measurement process, thus improving the accuracy and applicability of the measurement.
