Description

Technical Field

[0001] This utility model belongs to the technical field of welding auxiliary devices, specifically, it relates to an auxiliary support device for welding production of ultrasonic flow meters. Background Technology

[0002] An ultrasonic flow meter is a flow meter developed based on the principle that the propagation speed of ultrasonic waves in a flowing medium is equal to the vector sum of the average velocity of the measured medium and the velocity of the sound wave in a stationary medium. It mainly consists of a transducer and a converter, and comes in different types, including Doppler method, velocity difference method, beam deflection method, noise method, and correlation method. Ultrasonic flow meters typically have flanges at both ends for connecting the flow meter to pipelines or other equipment. The flow meter body is usually fixed to the flanges at both ends by welding. During the welding process, because circumferential welding is required, the welding skills of the operator are highly demanding, and multiple splicing operations are often needed to meet the circumferential welding requirements, resulting in low welding efficiency.

[0003] In view of this, this utility model is hereby proposed. Utility Model Content

[0024] like Figures 1 to 4As shown, an auxiliary support device for welding production of ultrasonic flowmeters includes a rotating power box 1 and a clamping power box 2.

The main shaft of the rotary motor 19 is connected to the lower end of the rotating shaft 15 through a coupling 20. A transmission screw 16 is installed in the cavity of the clamping power box 2. A movable nut seat 18 and a movable nut seat 2 17 are respectively installed on the transmission screw 16. A supporting inner claw 5 is fixedly installed above the movable nut seat 18, and a supporting inner claw 2 6 is fixedly installed above the movable nut seat 2 17. A clamping support upper platform 7 is correspondingly provided on the outer side of both the supporting inner claw 1 5 and the supporting inner claw 2 6. A clamping support lower platform 8 is provided below the clamping support upper platform 7. A clamping pad 9 is provided on the support surface of both the clamping support upper platform 7 and the clamping support lower platform 8 to protect the clamping position of the electromagnetic flowmeter body and the inner hole of the flange.

[0025] The clamping surfaces of the upper clamping support 7 and the lower clamping support 8 are both arc-shaped structures. The outer side of the clamping pad 9 is provided with a clamping engagement protrusion 10. The clamping engagement protrusion 10 is a longitudinal strip structure. The protruding surface of the clamping engagement protrusion 10 is arc-shaped to increase the contact area of ​​the clamping position and improve the stability of the clamping fixation.

[0026] The transmission screw 16 is a bidirectional screw. The threads of the first movable nut seat 18 and the second movable nut seat 17 are in opposite directions to ensure that the first movable nut seat 18 and the second movable nut seat 17 can move closer or separate synchronously during the rotation of the transmission screw 16.

[0027] Bearings are provided at the mating positions between the two ends of the transmission screw 16 and the inner wall of the clamping power box 2. A clamping adjustment mating hole 13 is provided at the end of the clamping power box 2. A clamping adjustment end 14 is provided at the end of the transmission screw 16. An internal hexagonal countersunk hole is provided on the end face of the clamping adjustment end 14 to facilitate the adjustment of the transmission screw 16 with a wrench. The transmission screw 16 is a self-locking screw.

[0028] A movable slide groove 3 is provided on the upper surface of the clamping power box 2. The lower ends of the supporting inner claw 1 5 and supporting inner claw 2 6 are fitted in the movable slide groove 3. A telescopic protective cover 4 is installed in the movable slide groove 3 to protect the transmission screw 16 assembly inside the clamping power box 2.

[0029] A control box 11 is fixedly installed on the outer wall of the rotating power box 1. The control box 11 has operation buttons 12 on its panel. The control box 11 is electrically connected to the rotating motor 19. The control box 11 is used to control the operation of the rotating motor 19.

[0031] The working principle of this utility model is as follows: When welding the main housing and flange of the ultrasonic flowmeter, firstly, a wrench and clamping adjustment end 14 are used to drive the transmission screw 16 to rotate, causing the moving nut seat 18 and the moving nut seat 2 17 to move closer together. This, in turn, causes the supporting inner claw 1 5 and the supporting inner claw 2 6 to move closer together, so that the through hole of the connecting flange is fitted onto the outside of the supporting inner claw 1 5 and the supporting inner claw 2 6. Then, the center hole of the ultrasonic flowmeter is fitted onto the outside of the supporting inner claw 1 5 and the supporting inner claw 2 6. The main body of the ultrasonic flowmeter is located above the connecting flange. Adjust the clamping adjustment end 14 to make the transmission screw 16 rotate in the opposite direction, causing the inner support claw 1 5 and inner support claw 2 6 to separate from each other, so that the clamping support upper platform 7 on the outside of the inner support claw 1 5 and inner support claw 2 6 contacts the inner wall of the ultrasonic flow meter body, and the clamping support lower platform 8 contacts the inner wall of the connecting flange. The clamping surfaces of the clamping support upper platform 7 and clamping support lower platform 8 are both arc surface structures, and clamping pads 9 are provided on the clamping arc surface structures. The clamping pads 9 are provided with clamping engagement protrusions 10 on the outside, to ensure the support effect of the inner support claw 1 5 and inner support claw 2 6 on the inner hole wall.

[0032] The rotary motor 19 is started by controlling the control box 11. The rotary motor 19 drives the rotating shaft 15 to rotate through the coupling 20, which in turn drives the clamping power box 2 to rotate synchronously. During the rotation, the mating position between the ultrasonic flow meter body and the connecting flange is welded. The mating position is provided with a welding bevel to ensure the welding quality. In order to ensure the welding quality, the rotary motor 19 is preferably a low-speed motor.

[0033] The welding auxiliary support of this utility model is equipped with adjustable inner support claws 5 and 6. The cooperation of inner support claws 5 and 6 is used to tighten the body of the ultrasonic flow meter and the inner hole of the flange. The adjustable support structure can meet the welding needs of ultrasonic flow meters with different orifice sizes. The rotating power box 1 is equipped with a rotary motor 19, which can drive the clamping power box 2 to rotate at a uniform speed. During the welding process, it is only necessary to align with one welding position to uniformly weld the circumference of the ultrasonic flow meter, effectively reducing the welding difficulty and improving the welding processing efficiency.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
