[0002] A beveling cutting device suitable for small and medium-sized cutting machines is available. It is mounted on the turntable of the cutting machine and rotates around the pipe during operation to cut a bevel on the pipe. This beveling cutting device includes a housing, a moving device on the upper side of the housing, and a swing seat at one end of the housing, which is fixed to the cutting head.

[0003] The existing beveling cutting device described above has at least the following shortcomings: 1. During non-working periods, the beveling cutting device is generally located above the pipe placement position with the cutting head facing downwards. Since the internal installation space of small and medium-sized cutting machines is limited, and because its moving mechanism is located on the top, it is difficult to disassemble and repair it from the side of the machine. Operation may require accessing the top of the machine, making disassembly for inspection and maintenance very inconvenient; 2. The cutting head is located at one end of the housing, resulting in a longer beveling cutting device. This may increase the difficulty of installation within the already limited installation space of small and medium-sized cutting machines; 3. In the existing beveling cutting device, the servo motor drives the cutting head via a belt. The belt is prone to damage, requiring frequent maintenance of the beveling cutting device.

[0031] like Figures 1 to 10 As shown, a bevel cutting device includes a housing 1, a first moving drive assembly 2, and a cutting assembly 3. The cutting assembly 3 is disposed on the housing 1. The first moving drive assembly 2 includes a first moving drive device 21, a first moving transmission assembly 22, and a first mounting plate 223. The first moving drive device 21 is disposed inside the housing 1. The first moving transmission assembly 22 includes a power transmission part 221 and a moving transmission part 222. The moving transmission part 222 is disposed on the side of the housing 1. The first moving drive device 21 and the moving transmission part 222 are connected by transmission through the power transmission part 221. The first mounting plate 223 is slidably connected to the side of the housing 1 where the moving transmission part 222 is disposed and is connected to the moving transmission part 222. The first moving drive device 21 can drive the housing 1 to move relative to the first mounting plate 223 in the X-axis direction.

[0032] In this embodiment, the bevel cutting device has the moving transmission part 222 of the first moving transmission assembly 22 and the first mounting plate 223 set on the side of the housing 1. This allows maintenance personnel to directly perform maintenance from the side of the bevel cutting device in the limited internal space of small and medium-sized cutting machines, making maintenance operations more convenient and efficient, thereby shortening maintenance time and ensuring production efficiency.

[0033] In some specific embodiments, reference is made to Figures 2 to 3 The first moving drive device 21 includes a first drive motor. The moving transmission part includes a first lead screw 2221 extending along the X-axis and a first lead screw nut 2222 screwed onto the first lead screw 2221. The first lead screw 2221 is rotatably disposed on the side of the housing 1. The power transmission part 221 includes a first driving wheel 2211, a first driven wheel 2212 and a first belt 2213 wound around the first driving wheel 2211 and the first driven wheel 2212. The first driving wheel 2211 is disposed on the shaft of the first drive motor and the first driven wheel 2212 is disposed on the first lead screw 2221. Both sides of the first lead screw 2221 are provided with first slide rails 2231 extending along the X-axis. The two first slide rails 2231 are arranged along the Y-axis. The first mounting plate 223 is engaged on the two first slide rails 2231 and can move along the first slide rails 2231. The first mounting plate 223 is fixedly connected to the first lead screw nut 2222.

[0034] Specifically, the shaft of the first drive motor extends along the X-axis, and the length of the motor housing of the first drive motor is also in the same direction as the X-axis. The first drive motor transmits power to the first lead screw 2221 through a combination of the first driving wheel 2211, the first driven wheel 2212, and the first belt 2213. This allows the placement of the first drive motor to extend along the X-axis, resulting in a smaller width of the bevel cutting device. This helps to reduce the space occupied by the bevel cutting device and makes it easier to install on the cutting machine in the very limited installation space of small and medium-sized cutting machines. The first mounting plate 223 is provided with a first slider 2232 and is slidably connected to the first slide rail 2231.

[0035] In other embodiments, the first moving transmission component 22 may also adopt a "helical gear component + chain" or other transmission structure, as long as it can drive the housing 1 to move relative to the first mounting plate 223 in the X-axis direction.

[0036] In some specific embodiments, reference is made to Figure 1 and Figure 4 The cutting assembly 3 includes a cutting head 31 and a swing drive motor 32. The main body of the swing drive motor 32 is located inside the housing 1. The rotating shaft of the swing drive motor 32 protrudes from the side of the housing 1 where the moving transmission part 222 is provided. The rotating shaft of the swing drive motor 32 extends along the Z-axis and is connected to the cutting head 31 for transmission, so as to drive the cutting head 31 to swing.

[0037] Specifically, within the housing 1, the first drive motor and the swing drive motor 32 are arranged along the X-axis. Unlike existing technologies, in this embodiment, the shaft of the swing drive motor 32 extends along the Z-axis, and the cutting head 31 is connected to the shaft via a transmission mechanism. This results in a shorter length of the bevel cutting device in the X-axis direction, which helps reduce the space occupied by the bevel cutting device. Furthermore, the shaft of the swing drive motor 32 protrudes from the side of the housing 1 where the moving transmission part 222 is located, and the cutting head 31 is also located on the side of the housing 1 where the moving transmission part 222 is located. This further reduces the length of the bevel cutting device in the Z-axis direction, making the structure of the bevel cutting device more compact and further reducing the space occupied by the bevel cutting device.

[0038] The oscillation drive motor 32 is specifically a harmonic motor, which is connected to the cutting head 31 through a harmonic reducer. Compared with the existing structure in which the servo motor drives the cutting head 31 to oscillate via belt transmission, the structure in this embodiment that directly drives the cutting head 31 to oscillate using a harmonic motor has fewer components, is simpler to install, and has a lower maintenance frequency, which is more conducive to improving production efficiency.

[0039] In some specific embodiments, reference is made to Figure 1 , Figures 5 to 9 The beveling device also includes a mounting frame 4 and a second moving drive assembly. The second moving drive assembly includes a second moving drive device 51, a second moving transmission assembly 52, and a second mounting plate 53. The mounting frame 4 is located beside the first mounting plate 223. The mounting frame 4 has two second slide rails 531 extending along the Y-axis on the side near the first mounting plate 223. The second mounting plate 53 is engaged with the two second slide rails 531 and can move along the second slide rails 531. The first mounting plate 223 is fixed to the second mounting plate 53. The second moving drive device 51 is located on the mounting frame 4. The second mounting plate 53 is connected to the second moving drive device 51 through the second moving drive assembly.

[0040] Specifically, the mounting bracket 4 is mounted on the cutting machine and remains fixed in the X-axis direction. The first mounting plate 223 is fixed to the second mounting plate 53, thus the first mounting plate 223 also remains fixed in the X-axis direction. When the first drive motor runs, the housing 1 and the first mounting plate 223 move relative to each other in the X-axis direction. Since the first mounting plate 223 is stationary in the X-axis direction, the housing 1 will move in the X-axis direction. The second mounting plate 53 is provided with a second slider 532, and is slidably connected to the second slide rail 531 through the second slider 532.

[0041] The beveling device also includes a second moving drive assembly to move the first mounting plate 223, the housing 1 and the cutting head 31 in the Y-axis direction.

[0042] In some specific embodiments, reference is made to Figures 5 to 7The second moving drive device 51 includes a second drive motor, and the second moving transmission assembly 52 includes a second lead screw 521 extending along the Y-axis and a second lead screw nut 522 screwed onto the second lead screw 521. The second lead screw 521 is rotatably disposed in the mounting bracket 4. The second lead screw 521 is drivenly connected to the second drive motor, and the second lead screw nut 522 is fixedly connected to the second mounting plate 53.

[0043] In some specific embodiments, including Figures 5 to 9 The second moving transmission assembly 52 also includes a third lead screw 7 extending along the Y-axis direction. The third lead screw 7 is rotatably mounted in the mounting frame 4. The second drive motor is coaxially fixedly connected to the third lead screw 7. The third lead screw 7 is provided with a second driving wheel 511, and the second lead screw 521 is provided with a second driven wheel 512. A second belt 513 is wound around the second driving wheel 511 and the second driven wheel 512. The threads on the second lead screw 521 and the third lead screw 7 are opposite in direction. A third lead screw nut 71 is screwed onto the third lead screw 7. The mounting frame 4 is provided with two third slide rails 61 extending along the Y-axis direction on the side away from the first mounting plate 223. A third mounting plate 6 for mounting the beveling cutting device onto the cutting machine is slidably connected to the two third slide rails 61.

[0044] The third mounting plate 6 is provided with a third slider 62, which is slidably connected to the third slide rail 61.

[0045] When the second drive motor is running, the second lead screw 521 and the third lead screw 7 rotate synchronously in the same direction. However, since the thread directions of the second lead screw 521 and the third lead screw 7 are opposite, the movement directions of the second lead screw nut 522 and the third lead screw nut 71 are opposite. For example, when the second lead screw 521 and the third lead screw 7 rotate synchronously in the clockwise direction, the third lead screw nut 71 moves upward relative to the third lead screw 7 in the Y-axis direction, and the second lead screw nut 522 moves downward relative to the second lead screw 521 in the Y-axis direction. In this case, since the third mounting plate 6 is mounted on the cutting machine, it can be considered to be stationary in the Y-axis direction. Therefore, the third lead screw nut 71 is also stationary in the Y-axis direction. Combining this with the statement that "the third lead screw nut 71 moves upward relative to the third lead screw 7," the third lead screw 7 will move downward along the Y-axis direction, causing the entire mounting frame 4 to move downward. Meanwhile, the second lead screw nut 522 moves downward relative to the second lead screw 521 in the Y-axis direction, meaning that the second lead screw nut 522 can drive the housing 1 and the cutting head 31 to move downward. In summary, the third lead screw 7 and the third lead screw nut 71 drive the mounting bracket 4 downwards, while the second lead screw 521 and the second lead screw nut 522 drive the housing 1 and the cutting head 31 downwards. This ensures that the total downward stroke of the housing 1 and the cutting head 31 is greater than the stroke of either the second lead screw 521 or the third lead screw 7, and is close to the sum of the strokes of the second lead screw 521 and the third lead screw 7. When it is necessary for the housing 1 and the cutting head 31 to move upwards along the Y-axis, the second drive motor simply reverses its direction.

[0046] refer to Figure 9 This design shortens the length of the lead screw on the mounting bracket 4, thereby reducing the length of the mounting bracket 4 in the Y-axis direction. At the same time, it allows the housing 1 and the cutting head 31 to achieve a larger stroke in the Y-axis direction. This helps to shorten the length of the mounting bracket 4, reduce the space occupied by the bevel cutting device, and make it easier to install the bevel cutting device on small and medium-sized cutting machines. It also helps to expand the stroke of the housing 1 and the cutting head 31 in the Y-axis direction of the bevel cutting device, making the cooperation between the bevel cutting device and other parts of the cutting machine more versatile.

[0047] In some specific embodiments, reference is made to Figure 8 and Figure 10 The mounting frame 4 includes an upper end plate 41 and a lower end plate 44 arranged along the Y-axis, and a first side plate 42 and a second side plate 43 arranged along the Z-axis. The mounting frame 4 also includes a support block 8, which connects the first side plate 42 and the second side plate 43. The support block 8 has two clearance grooves 81 that correspond to the positions of the second lead screw nut 522 and the third lead screw nut 71, respectively.

[0048] The support block strengthens the mounting bracket 4, making it less prone to deformation. Two clearance slots 81 are provided on the support block 8 to ensure unobstructed movement of the second lead screw nut 522 and the third lead screw nut 71 on the second lead screw 521 and the third lead screw 7, respectively.

[0049] Two second slide rails 531 are respectively disposed on the sides of the first side plate 42 and the second side plate 43 near the first mounting plate 223, and two third slide rails 61 are respectively disposed on the sides of the first side plate 42 and the second side plate 43 away from the first mounting plate 223.

[0050] This embodiment also discloses a cutting machine, including the above-mentioned beveling cutting device.

[0051] In some specific embodiments, the bevel cutting device further includes a mounting frame 4, a first mounting plate 223 is disposed on the mounting frame 4, and the cutting machine further includes a turntable, with the mounting frame 4 drivenly disposed on the turntable.

[0052] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
