[0002] An insertion flowmeter is a device used to measure the flow rate of liquids or gases in a pipeline, and is also known as a differential pressure flowmeter. Its working principle is mainly based on different physical principles, such as the Karman vortex principle, Faraday's law of electromagnetic induction, etc., specifically depending on the type of flowmeter.

[0018] 1. For this insertion type flowmeter installation tooling structure, the arc-shaped rubber cushion strips on the upper clamping plate will be deformed under the clamping force. At this time, the surface rod can be firmly fixed between the moving tooling base and the upper clamping plate. Then, manually move the moving tooling base to the required position.

Two mounting plates 4 are movably installed on the aluminum profile chute rail 1, and screw holes for adjusting the installation and fixing positions are provided on both mounting plates 4;

[0032] Pneumatic push rods 5 are fixedly connected and installed on both mounting plates 4. The output ends of the two pneumatic push rods 5 are fixedly sleeved with tooling top blocks 6 for respectively pressing against the meter rod and the probe. A V-shaped tooling 3 for placing the probe is fixedly connected to one side of the mounting plate 4;

[0033] A locking mechanism is provided on the moving tooling seat 2, and the locking mechanism is used to lock and fix the meter rod. The locking mechanism includes an upper clamping plate 7, an arc-shaped rubber gasket strip 9, a pressing plate 10, and a rotating slot block 12;

[0034] A positioning and adjusting component is provided on the moving tooling seat 2, and the positioning and adjusting component is used to adjust and fix the position of the moving tooling seat 2. The positioning and adjusting component includes a cushion block 11, a long eccentric wheel 14, and a circumferential groove 17.

[0035] Furthermore, the locking mechanism further includes two side fixing plates 8, which are respectively fixedly connected to both sides of the moving tooling seat 2, and two rotating slot blocks 12 are respectively rotatably connected to the opposite sides of the two side fixing plates 8.

[0036] Further, both pressing plates 10 are rotatably connected to the upper clamping plate 7. A torsion spring is arranged between the pressing plate 10 and the upper clamping plate 7. The torsion spring is used to drive the pressing plate 10 to rotate downward. The two pressing plates 10 are respectively adapted to the corresponding rotating clamping groove blocks 12. The rotating clamping groove blocks 12 are used to clamp the upper clamping plate 7. A locking handle 16 is fixedly connected between the two rotating clamping groove blocks 12.

[0037] Further, the upper clamping plate 7 is rotatably connected to one side position of the upper surface of the moving tooling seat 2. A plurality of arc-shaped rubber cushion strips 9 are uniformly fixed on the inner surface of the upper clamping plate 7 of the aluminum profile chute rail 1. The arc-shaped rubber cushion strips 9 are used to improve the axial fixing force and can effectively prevent the meter rod from sliding horizontally.

[0038] Further, the positioning and adjusting assembly further includes an eccentric wheel fixing seat 13. The eccentric wheel fixing seat 13 is fixedly connected to the outer surface of the moving tooling seat 2. A long eccentric wheel 14 is rotatably connected inside the eccentric wheel fixing seat 13. A plurality of circumferential grooves 17 for improving the axial friction force are uniformly formed on the outer surface of the long eccentric wheel 14.

[0039] Further, a positioning handle 15 is fixedly connected to the long eccentric wheel 14. The cushion block 11 is fixedly connected to the outer surface of the aluminum profile chute rail 1. The long eccentric wheel 14 is used to lock the cushion block 11.

[0040] Further, during use, the meter rod and the probe to be assembled are placed on the corresponding moving tooling seat 2 and the V-shaped tooling 3, and then the upper clamping plate 7 is closed. The locking handle 16 is manually rotated outward. At this time, the pressing plate 10 will enter the rotating clamping groove block 12. At this time, the locking handle 16 is pulled upward. The locking handle 16 presses the pressing plate 10 tightly through the rotating clamping groove block 12, so that the upper clamping plate 7 can clamp the meter rod on the moving tooling seat 2. This effectively restricts the axial movement of the meter rod, avoids the installation failure caused by unstable fixing of the meter rod accessories, and also improves the assembly efficiency of the insertion type flowmeter.

[0041] Further, at the same time, the arc-shaped rubber cushion strip 9 on the upper clamping plate 7 will deform under the clamping force. At this time, the meter rod can be firmly fixed between the moving tooling seat 2 and the upper clamping plate 7. Then the moving tooling seat 2 is manually moved to the required position. At this time, by pulling up the positioning handle 15, the positioning handle 15 drives the long eccentric wheel 14 to rotate. The eccentric protrusion part of the long eccentric wheel 14 will apply a force to the cushion block 11 and press it tightly. Under the action of the plurality of circumferential grooves 17, it is pressed tightly on the cushion block 11. This effectively fixes the position of the moving tooling seat 2 at this time, improves the assembly stability of the meter rod and the probe, and can also avoid the assembly failure caused by unstable fixing of the accessories to a certain extent when the pneumatic push rod 5 assembles the meter rod and the probe, and also improves the assembly efficiency of the insertion type flowmeter.

[0042] Further, by activating the corresponding pneumatic push rod 5, the pneumatic push rod 5 can drive the tooling top block 6 on the aluminum profile chute rail 1 to combine the meter rod and the probe, completing one assembly.

[0043] Further, by machining the dimensions of the moving tooling seat 2 and the V-shaped tooling 3 according to the dimensions of the meter rod and the probe respectively, the meter rod and the probe can be accurately positioned, ensuring concentricity during the installation of the meter rod and the probe.

[0044] Further, by setting two pneumatic push rods 5, when in use, they simultaneously provide uniform thrust to combine the meter rod and the probe. Uniform force application can reduce unnecessary damage to parts caused by uneven force.

[0045] Further, the positioning and adjusting component can be adjusted according to the different lengths of the meter rod. This device can be used for the assembly of plug-in flowmeter bodies with different lengths, which improves the adaptability to flowmeter bodies of different lengths.

[0046] Working principle: When in use, place the meter rod and the probe to be assembled on the corresponding moving tooling seat 2 and V-shaped tooling 3, then close the upper clamping plate 7 and manually rotate the locking handle 16 outwards. At this time, the pressing plate 10 will enter the rotating slot block 12. Then, pull the locking handle 16 upwards. The locking handle 16 will push the pressing plate 10 tightly through the rotating slot block 12, so that the upper clamping plate 7 can clamp the meter rod on the moving tooling seat 2.

[0047] Further, at the same time, the arc-shaped rubber gasket strip 9 on the upper clamping plate 7 will deform under the clamping force. At this time, the meter rod can be firmly fixed between the moving tooling seat 2 and the upper clamping plate 7. Then, manually move the moving tooling seat 2 to the required position. At this time, by pulling the positioning handle 15 upwards, the positioning handle 15 drives the long eccentric wheel 14 to rotate. The eccentric protruding part of the long eccentric wheel 14 will apply a force to the spacer block 11 and push it tightly. Under the action of multiple circumferential grooves 17, it is pushed tightly on the spacer block 11, which effectively fixes the position of the moving tooling seat 2 at this time.
