Description

Technical Field

[0001] The utility model relates to the technical field of flange hole processing, in particular to a flowmeter flange hole processing device. Background Art

[0002] A flowmeter is an instrument used to measure the flow rate of fluids (including liquids and gases) in pipelines or open channels. It has a wide range of applications in industrial automation, process control, and energy metering. Flowmeters are typically installed on pipelines using flange connections. After the flowmeter valve body is cast, flange holes are machined at both ends to facilitate subsequent flange connection.

[0003] When machining flange holes at both ends of a flowmeter's valve body, existing flange hole machining equipment requires disassembling and rotating the valve body after machining one end, allowing machining of the other end. However, during this rotation, the valve body must be disassembled and clamped again, and the fixing angle of the valve body must be readjusted to prevent relative offset of the flange holes at both ends. This process can easily reduce machining efficiency. Therefore, those skilled in the art have provided a flowmeter flange hole machining device to address the problems raised in the aforementioned background technology. Utility Model Content

[0004] In response to the deficiencies in the prior art, the utility model provides a flowmeter flange hole processing device to solve the problem that when the flange hole processing equipment processes the flange holes at both ends of the valve body of the flowmeter, the valve body needs to be disassembled and rotated after processing one end so as to process the other end of the valve body. In addition, during the valve body rotation process, the valve body needs to be disassembled and clamped again, and the fixed angle of the valve body needs to be readjusted to avoid the problem of relative offset of the flange holes at both ends. This process can easily lead to a problem of reduced processing efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flow meter flange hole processing device, comprising a base plate, a punching unit is installed on the base plate, a frustum is provided on one side of the punching unit, positioning holes are symmetrically provided on both sides of the frustum, a round cover is provided on the frustum, a ball is installed on the inside of the round cover, the ball contacts the upper surface of the frustum, a limiting groove is provided on one side of the round cover, a positioning bolt is inserted in the limiting groove, a limiting ring is installed on the positioning bolt, a spring is provided on the positioning bolt, a movable plate is provided on the round cover, and a splint is provided on one side of the movable plate.

[0006] Preferably, one end of the spring is pressed against the inner wall of the limiting groove, and the other end of the spring is pressed against the limiting ring, the circular cover is rotatably connected to the circular table, and the positioning bolt is positioned and plugged into the positioning hole. After the punching unit punches a hole in one end of the fixed flow meter valve body, the positioning bolt is pulled out, and then the circular cover is rotated. When the positioning bolt is rotated to the other side, the positioning bolt is plugged into the positioning hole on the other side of the circular table, thereby ensuring that the flow meter valve body fixed on the circular cover is flipped over, so that the other end of the flow meter valve body can be punched without disassembling the flow meter valve body.

[0007] Preferably, a first sliding groove is provided on the round cover, and a first bidirectional screw is rotatably engaged in the first sliding groove. A first slider is installed at the bottom of the movable plate, and the movable plate is slidably engaged with the first sliding groove through the first slider. The first slider is threadedly engaged with the first bidirectional screw. By rotating the first bidirectional screw, the two movable plates can be moved relative to each other, thereby driving the clamping plate on the movable plate to clamp the flow meter valve body.

[0008] Preferably, a second slide groove is provided on the movable plate, a through hole is provided on one side of the second slide groove, a second bidirectional screw is rotatably engaged in the through hole, a second slider is installed on one side of the clamping plate, the clamping plate is slidably engaged with the second slide groove through the second slider, the second slider is threadedly sleeved with the second bidirectional screw, and the clamping plate can be adjusted in spacing under the rotation of the second bidirectional screw, so as to be suitable for flow meter valve bodies of different specifications.

[0009] Compared with the prior art, the present invention provides a flowmeter flange hole processing device with the following beneficial effects:

After the punching unit punches a hole on one end of the fixed flow meter valve body, the positioning bolt is pulled out, and then the round cover is rotated. When the positioning bolt is rotated to the other side, the positioning bolt is plugged into the positioning hole on the other side of the frustum, thereby ensuring that the flow meter valve body fixed on the round cover is flipped 90°, so that the other end of the flow meter valve body can be punched without disassembling the flow meter valve body, and the hole positions at both ends are aligned without deviation, thereby ensuring the processing efficiency of the flange hole.
