Description

Technical Field

[0001] This utility model relates to the technical field of flow meter production equipment, specifically an adjustable assembly fixture for flow meter production. Background Technology

[0002] Flow meters are instruments used to measure the flow rate of fluids in pipes or open channels, and they have wide applications in industrial production, energy management, environmental protection, and other fields. Different types of flow meters operate on different principles. Turbine flow meters, for example, use fluid to drive an impeller to rotate; the impeller speed is proportional to the flow velocity, and the flow rate is calculated by measuring the impeller speed. Electromagnetic flow meters, on the other hand, use conductive liquid cutting a magnetic field to generate an induced electromotive force (EMF); the magnitude of this EMF is proportional to the flow velocity, and the flow rate is calculated by measuring the EMF. Ultrasonic flow meters utilize the time difference of ultrasonic waves propagating in the fluid or the Doppler effect to measure the flow velocity and then calculate the flow rate.

[0003] Assembly fixtures are required in the production of flow meters. Utility model patent CN219027283U discloses a fixture for producing electronic flow meters for medical oxygen concentrators, including a processing table and a clamping structure. A rotating shaft is fixed to the inner side of the processing table, and a rotating seat is movably mounted on the top of the rotating shaft. A limit box is fixed to the inner side of the rotating seat. This utility model utilizes a clamping plate, a movable plate, a spring, and a support plate. A first motor drives a lead screw to rotate, and the lead screw, through opposite-direction threads, drives two nut blocks and the support plate to move in the opposite direction, approaching the flow meter. When the support plate moves, the clamping plate on the inner wall clamps and fixes the bottom of the flow meter. The movable plate at the top of the clamping plate approaches the upper part of the flow meter via a hinge. The two movable plates contact the upper part of the flow meter, and the spring on the connecting plate compresses the movable plates, tightly clamping them to the outside of the flow meter. Thus, the flow meter is fixed under the clamping of the clamping plate and the movable plate.

[0004] However, when using the flow meter manufacturing fixture, the clamping is performed in two symmetrical directions, resulting in no restriction on the two sides perpendicular to the clamping surface. During assembly or processing, the parts are prone to tipping over. Therefore, an adjustable assembly fixture for flow meter manufacturing is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an adjustable assembly fixture for flow meter production, which has advantages such as improving the stability of flow meter fixtures and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An adjustable assembly fixture for flow meter production includes an assembly platform, a clamping base fixedly mounted on the top of the assembly platform, a fixed square tube fixedly mounted on the top of the clamping base, and a movable square tube slidably mounted on the top of the clamping base. Both the fixed square tube and the movable square tube are provided with side clamping components. The side clamp assembly includes a bidirectional screw that is rotatably installed on the inner sidewall of the fixed square tube and the movable square tube. Two side clamp sliders are threadedly connected to the surface of the bidirectional screw. A side clamp connecting block is fixedly installed on one side of the side clamp slider, and a side clamp plate is fixedly installed on one side of the side clamp connecting block. Side clamp buffer pads are fixedly installed on the opposite sides of the two side clamp plates.

[0007] Furthermore, a side clamp knob is rotatably installed on one side of both the fixed square tube and the movable square tube, and the side clamp knob is fixedly connected to one end of the bidirectional screw.

[0008] Furthermore, a clamping slider is slidably installed inside the clamping base, and a clamping connecting block is fixedly installed on the top of the clamping slider.

[0009] Furthermore, the top of the clamping connecting block is fixedly connected to the bottom of the movable square tube, and clamping buffer pads are fixedly installed on the opposite sides of both the fixed square tube and the movable square tube.

[0010] Furthermore, a clamping screw is rotatably mounted on the inner side wall of the clamping base, and the clamping screw is threadedly connected to the clamping slider.

[0011] Furthermore, a clamping motor is fixedly installed on one side of the clamping base, and the output shaft of the clamping motor is fixedly connected to one end of the clamping screw.

[0012] Furthermore, the top of the clamping base is provided with a clamping through hole that is adapted to the clamping connecting block, and the side of the fixed square tube and the movable square tube opposite to each other is provided with a side clamping through hole that is adapted to the side clamping connecting block.

[0013] Furthermore, support legs are fixedly installed at the four corners of the bottom of the assembly platform, and support base plates are fixedly installed at the bottom ends of the support legs.

[0014] Compared with the prior art, this utility model provides an adjustable assembly fixture for flow meter production, which has the following advantages: This adjustable assembly fixture for flowmeter production uses a side clamping assembly on one side of a fixed square tube and a movable square tube. A side clamping knob drives a bidirectional screw to rotate, causing the side clamping slider to move synchronously in opposite directions. After the fixed and movable square tubes clamp the flowmeter components, the side clamping plates further clamp the sides of the flowmeter components, preventing them from tipping over during processing or assembly. This solves the problem of common flowmeter production fixtures that use symmetrical clamping in two directions, leaving the sides perpendicular to the clamping surface unrestricted and prone to tipping over during assembly or processing.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 4 This embodiment discloses an adjustable assembly fixture for flowmeter production, comprising an assembly platform 1, a clamping base 2 fixedly mounted on the top of the assembly platform 1, a fixed square tube 3 fixedly mounted on the top of the clamping base 2, and a movable square tube 4 slidably mounted on the top of the clamping base 2. Side clamping assemblies are provided on both the fixed square tube 3 and the movable square tube 4. Flowmeter components are placed between the fixed square tube 3 and the movable square tube 4, and the movable square tube 4 moves to clamp the components.

[0019] The side clamping assembly includes a bidirectional screw 5 rotatably mounted on the inner wall of the fixed square tube 3 and the movable square tube 4. Two side clamping sliders 6 are threaded onto the surface of the bidirectional screw 5.

Side clamping buffer pads 9 are fixedly mounted on opposite sides of each of the two side clamping plates 8. Rotation of the bidirectional screw 5 causes the two side clamping sliders 6 to move synchronously in opposite directions. This movement, via the side clamping connecting block 7, causes the side clamping plates 8 to move, clamping the other two sides of the component and preventing it from shifting or tipping over.

[0020] Secondly, a side clamp knob 10 is rotatably installed on one side of both the fixed square tube 3 and the movable square tube 4, and the side clamp knob 10 is fixedly connected to one end of the bidirectional screw 5. By rotating the side clamp knob 10, the bidirectional screw 5 is driven to rotate.

[0021] Specifically, the flow meter components are placed between the fixed square tube 3 and the movable square tube 4. The movable square tube 4 moves to clamp the components. By rotating the side clamp knob 10, the bidirectional screw 5 is rotated, which drives the two side clamp sliders 6 to move in opposite directions in sync.

[0024] Meanwhile, a clamping screw 14 is rotatably installed on the inner side wall of the clamping base 2, and the clamping screw 14 is threadedly connected to the clamping slider 11.

[0025] A clamping motor 15 is fixedly installed on one side of the clamping base 2, and the output shaft of the clamping motor 15 is fixedly connected to one end of the clamping screw 14. The clamping motor 15 drives the clamping screw 14 to rotate, which in turn drives the clamping slider 11 to move. Through the clamping connecting block 12, the movable square tube 4 is moved to clamp the components of the flow meter.

[0026] Please see Figure 1 and Figure 4 In this embodiment, the top of the clamping base 2 is provided with a clamping through hole 16 that is adapted to the clamping connecting block 12, and the side opposite to the fixed square tube 3 and the movable square tube 4 is provided with a side clamping through hole 19 that is adapted to the side clamping connecting block 7.

[0028] The working principle of the above embodiment is as follows: the flow meter components are placed between the fixed square tube 3 and the movable square tube 4. The clamping motor 15 drives the clamping screw 14 to rotate, which in turn drives the movable square tube 4 to move and clamp the flow meter components. By rotating the side clamping knob 10, the side clamping plate 8 is moved to clamp the other two sides of the components.
