Description

Technical Field

[0002] A butterfly valve, also known as a flap valve, is a simple regulating valve that can be used for on / off control of low-pressure pipeline media. A butterfly valve is a valve in which the closing element (valve disc or butterfly plate) is a disc that rotates around the valve shaft to achieve opening and closing. When manufacturing butterfly valves, the end face needs to be machined using an end milling machine.

[0003] For example, CN209255937U discloses a milling machine for processing butterfly valves, including a spindle box, a milling cutter, and a worktable. The spindle box is mounted on an axial robotic arm, a servo device is mounted on the side of the axial robotic arm, a linkage device is mounted on the servo device, a CNC system is mounted on the linkage device, the milling cutter is mounted on a tool mounting axis, the tool mounting axis is located at the bottom of the spindle box, and a workpiece clamping device is mounted on the worktable.

[0004] In the prior art, milling machines generate chips during machining, which need to be cleaned. However, the fixed angle of the cleaning nozzle results in a limited cleaning range, and fine chips are easy to remain. The fine chips generated during machining have strong adhesion and are very easy to stick to the worktable or the machined butterfly valve end face. They are difficult to completely remove under the fixed angle of spraying, resulting in a large amount of chip residue. This residue will rub and scratch the machined surface in subsequent processes, causing surface scratches and roughness exceeding the tolerance. Utility Model Content

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention.

Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-4As shown, this utility model provides an end face milling machine for butterfly valve production, including a worktable 1.

One end of one support plate 21 is rotatably connected to two rotating rods 29. One end of the two rotating rods 29 is fixedly connected to a connecting pipe 23. One end of the connecting pipe 23 passes through the other support plate 21 and is fixedly connected to a three-way pipe 22. Gears 24 are fixedly connected to the outside of the rotating rods 29. One side of the two gears 24 meshes with a rack 25. A moving bar 27 is fixedly connected between the two racks 25. A guide block 26 is slidably connected to the outside of the moving bar 27. One side of the guide block 26 is fixedly connected to one side of one of the support plates 21. An electric push rod 28 is fixedly connected to one side of the moving bar 27. One side of the electric push rod 28 is fixedly connected to one side of one of the support plates 21.

[0024] The electric push rod 28 drives the moving bar 27 to move. The moving bar 27 slides inside the guide block 26. The fixed moving bar 27 moves in a straight line. The movement of the moving bar 27 drives the two racks 25 to move. The teeth of the two racks 25 are set on opposite sides, which can drive the two meshing gears 24 to rotate in opposite directions. The rotating rod 29 and the connecting pipe 23 rotate accordingly, adjusting the spray angle of the nozzle on the connecting pipe 23. The nozzle can tilt and rotate at a certain angle to increase the cleaning range. One end of the three-way pipe 22 is connected to a high-pressure pump, and the high-pressure airflow passes through the three-way pipe 22 and the connecting pipe 23 and blows out from the nozzle on the connecting pipe 23. After the workpiece is processed, the air is automatically sprayed to remove residual fine chips and prevent the chips from scratching the processed surface. The surface of the worktable 1 is distributed with honeycomb chip removal holes, and the chips can slide off the table by gravity.

[0025] Example 2: Figures 1-4As shown, the positioning mechanism 3 includes a fixed frame 37, with a threaded rod 33 rotatably connected inside the fixed frame 37. One end of the threaded rod 33 passes through one side of the fixed frame 37 and is fixedly connected to a first motor 32. One side of the first motor 32 is fixedly connected to one side of the fixed frame 37. Positioning blocks 34 are threadedly connected to both sides of the middle part of the threaded rod 33, and the positioning blocks 34 are slidably connected to one side of the fixed frame 37. A flip plate 38 is fixedly connected to the other side of the fixed frame 37. Both ends of the flip plate 38 are fixedly connected to steering bearings 36. Fixed seats 31 are rotatably connected to the outside of the two steering bearings 36. One side of the fixed seat 31 is fixedly connected to the top side of the worktable 1. A second motor 35 is fixedly connected to one side of one of the fixed seats 31. The output end of the second motor 35 is fixedly connected to one end of the steering bearing 36. A third linear module 6 is installed on both sides of the worktable 1. A second linear module 5 is installed on one side of the third linear module 6. A first linear module 4 is installed on one side of the second linear module 5. A tool assembly 7 is installed on one side of the first linear module 4.

[0026] The overall effect of this embodiment is as follows: the butterfly valve workpiece to be processed is placed on the fixed frame 37, the first motor 32 drives the threaded rod 33 to rotate, the threads on both sides of the middle of the threaded rod 33 are set in opposite directions, driving the two threaded positioning blocks 34 to move, thereby clamping and fixing the butterfly valve workpiece. The second motor 35 is a geared motor, and the second motor 35 drives the steering bearing 36 to rotate, which can adjust the angle of the flip plate 38 to adjust the processing angle of the butterfly valve workpiece. At the same time, after processing is completed, the flip plate 38 can be flipped so that the chips above it fall off under the action of gravity, preventing it from affecting subsequent processing. Through the cooperation between the first linear module 4, the second linear module 5 and the third linear module 6, the position of the tool assembly 7 is moved to process different parts of the butterfly valve workpiece.

[0027] The device's operation and working principle are as follows: The butterfly valve workpiece to be processed is placed on the fixed frame 37. The first motor 32 drives the threaded rod 33 to rotate, causing the two positioning blocks 34 to move and clamp the butterfly valve workpiece. The second motor 35 drives the steering bearing 36 to rotate, adjusting the angle of the flipping plate 38 to adjust the processing angle of the butterfly valve workpiece. After processing, the flipping plate 38 can be flipped to allow the chips above to fall off under gravity. The chips are then processed through the first linear module 4, the second linear module 5, and the third linear module. The movement of the tool assembly 7, coordinated between 6, allows for machining of different parts of the butterfly valve workpiece. The electric push rod 28 drives the moving bar 27 to move, which in turn drives the two racks 25 to move, causing the two meshing gears 24 to rotate in opposite directions. The rotating rod 29 and the connecting pipe 23 rotate accordingly, adjusting the spray angle of the nozzle on the connecting pipe 23. A high-pressure pump is connected to one end of the three-way pipe 22, and the high-pressure airflow passes through the three-way pipe 22 and the connecting pipe 23, blowing out from the nozzle on the connecting pipe 23. After the workpiece is machined, the air is automatically sprayed, and the chips can slide off the table by gravity.
