Description

Technical Field

[0001] This application relates to the field of milling apparatus for beveling machines, and in particular to a milling apparatus for beveling machines. Background Technology

[0002] A beveling machine is a metal processing device primarily used to cut bevels at specific angles on the edges of metal sheets or pipes for welding, splicing, or other processing operations. However, when faced with beveling tasks involving large-diameter pipes, existing equipment has revealed some problems that urgently need to be addressed.

[0003] A beveling machine typically consists of two parts: a clamping device and a milling device. The clamping device is responsible for fixing the tube body and ensuring its stability during processing; while the milling device is used to precisely bevele the ends of the tube body. However, in actual operation, due to the wide variety of tube diameters, existing milling devices often only meet the processing needs of tubes with specific diameters. When processing tubes of different diameters is required, operators must readjust the position of the milling device and perform a tedious recalibration process. This process is not only time-consuming and labor-intensive but also severely impacts processing efficiency, significantly reduces production speed, and causes numerous inconveniences to the company's production operations.

One end of the rotating shaft is coaxially fixedly mounted on the side of the rotating disk; The rotating shaft rotates about its own axis via the first driving unit.

[0007] Optionally, the second drive source includes a transmission rod, a threaded cylinder, and a threaded rod, wherein: The transmission rod is coaxially placed inside the rotating shaft, and the transmission rod rotates around its own axis through the second drive unit; The threaded cylinder is disposed inside the rotating disk, the axis of the threaded cylinder coincides with the axis of the rotating disk, and the threaded cylinder rotates around the axis of the threaded cylinder in a rotatable engagement with the rotating disk; the transmission rod and the threaded cylinder are in a transmission engagement. The threaded rod is coaxial with the threaded cylinder and is threadedly connected to the threaded cylinder. Both ends of the threaded rod are mounted on the milling tool holder and are rotatably engaged with the milling tool holder. The milling tool holder slides in a radial engagement with the rotary disk.

[0008] Optionally, a mounting ring is provided at one end of the rotating shaft near the rotating disk; The mounting ring has a transmission cylinder on its side wall. The axis of the transmission cylinder is parallel to the axis of the mounting ring. A first circular toothed ring and a first conical toothed ring are coaxially provided on the cylinder wall of the transmission cylinder. The end of the transmission rod is coaxially provided with a second circular gear ring that meshes with the first circular gear ring; The end of the threaded cylinder is provided with a second conical ring that meshes with the first conical ring.

[0009] Optionally, the rotary disk is provided with a pair of stop bars, and the milling cutter holder is placed between the pair of stop bars, with the milling cutter holder slidingly engaged with the stop bars along the radial direction of the rotary disk.

[0010] Optionally, the mounting frame is provided with a speed adjustment rod, which passes through the mounting frame and rotates around its own axis in cooperation with the mounting frame; The first gear ring group is coaxially mounted on the speed adjustment rod, and the second gear ring group is coaxially mounted on the outer wall of the rotating shaft.

[0012] Optionally, the mounting frame is provided with a support plate at its bottom, and the support plate is provided with a base at its bottom; The support plate and the base move along the axis of the rotating disk via a lead screw module.

[0013] In summary, this application includes at least one of the following beneficial technical effects: 1. The transmission rod is coaxially housed inside a hollow rotating shaft. This structural design makes the movement of the transmission rod more stable. Because the transmission rod is encased in the hollow rotating shaft, it experiences less external interference during rotation, enabling more precise power transmission from the second drive unit to the threaded cylinder. When the motor drives the transmission rod to rotate, the transmission rod can stably transmit rotational motion to the threaded cylinder, thereby driving the threaded rod and milling tool holder to move. This stable power transmission reduces energy loss and improves the power transmission efficiency of the entire device. 2. The transmission rod is housed within a hollow rotating shaft, resulting in a more compact overall structure. This compact design not only saves space but also ensures a tighter fit between components. In practical applications, the compact structure reduces the footprint of the device, facilitating installation and operation in limited spaces. Furthermore, the compact structure means more robust connections between components, reducing the risk of malfunctions due to loose parts and improving the reliability of the device. 3. The transmission rod, through its transmission engagement with the threaded cylinder, can precisely control the radial position of the milling cutter holder. When the transmission rod rotates, it drives the threaded cylinder to rotate. The threaded connection between the threaded cylinder and the threaded rod allows the threaded rod to move along its own axis, thereby causing the milling cutter holder to slide on the rotary table. This transmission method allows for quick and precise adjustment of the milling cutter position according to different pipe diameters, adapting to the pipe diameter and improving machining flexibility and accuracy.

[0021] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0022] This application discloses a milling device for a beveling machine.

[0023] A milling device for a beveling machine includes a mounting frame 1, a rotary disk 2, and a milling tool holder 3. A support plate 4 is horizontally fixedly mounted on the bottom of the mounting frame 1. A base 5 is fixedly positioned at the bottom of the support plate 4. A lead screw module 6 is provided between the support plate 4 and the base 5. The support plate 4 drives the mounting frame 1 to move along an axis parallel to the rotary disk 2 via the lead screw module 6. The rotary disk 2 is mounted on the side of the mounting frame 1 and rotates around its own axis in coordination with the mounting frame 1, rotating via a first drive source 7. The milling tool holder 3 is mounted on the rotary disk 2 and can move relative to the rotary disk 2 radially via a second drive source 8. Milling tools are mounted on the milling tool holder 3.

[0024] After the axes of the tube body and the rotating disk 2 are aligned, when the tube body needs to be beveled, the milling cutter holder 3 is moved radially along the rotating disk 2 by the second drive source 8 according to the diameter of the tube body, so that the rotation diameter of the rotating cutter on the rotating cutter holder is adapted to the diameter of the tube body. Then, the lead screw module 6 on the base 5 moves along the axial direction of the rotating disk 2, so that the milling cutter contacts the tube body, and the rotating disk 2 is driven to rotate by the first drive source 7. The rotation of the rotating disk 2 causes the milling cutter to rotate, and the tube body is beveled during the rotation of the milling cutter.

[0025] The first drive source 7 includes a hollow rotating shaft 71 and a first drive unit. The rotating shaft 71 passes through the mounting frame 1 and rotates around the axis of the rotating shaft 71 in a rotatable engagement with the mounting frame 1. One end of the rotating shaft 71 is coaxially fixedly mounted on the side of the rotating disk 2. The rotating shaft 71 rotates around its own axis through the first drive unit.

[0026] The rotating shaft 71 is mounted on the mounting frame 1, and the rotating disk 2 is fixedly mounted on the rotating shaft 71 by bolts. The mounting frame 1 supports the rotating disk 2 through the rotating shaft 71, thereby improving the ease of installation of the rotating disk 2. At the same time, during the rotation of the rotating shaft 71, the mounting frame 1 guides and limits the rotating shaft 71, further improving the stability of the rotating shaft 71 and the rotating disk 2.

[0027] The second drive source 8 includes a transmission rod 81, a threaded cylinder 82, and a threaded rod 83. The transmission rod 81 is coaxially placed inside the rotating shaft 71 and rotates around its own axis via the second drive unit 84. The threaded cylinder 82 is located inside the rotating disk 2, and its axis coincides with the axis of the rotating disk 2. The threaded cylinder 82 rotates around the axis of the rotating disk 2, and the transmission rod 81 and the threaded cylinder 82 are in a transmission engagement. The threaded rod 83 is coaxial with the threaded cylinder 82 and is threadedly connected to the threaded cylinder 82. Both ends of the threaded rod 83 are located on the milling tool holder 3 and rotate in engagement with the milling tool holder 3. The milling tool holder 3 slides in engagement with the rotating disk 2 along the radial direction of the rotating disk 2.

[0028] The transmission rod 81 is housed within a hollow rotating shaft 71, which protects the transmission rod 81. Furthermore, the placement of the transmission rod 81 within the rotating shaft 71 contributes to a more compact overall structure. When the position of the milling tool holder 3 needs adjustment, the rotating transmission rod 81 drives the threaded cylinder 82 to rotate. Since the threaded cylinder 82 and the threaded rod 83 are threadedly connected, and the end of the threaded rod 83 is mounted on the milling tool holder 3, the rotating threaded cylinder 82 and the threaded rod 83 move relative to each other along their own axes during rotation, thereby causing the milling tool holder 3 to slide on the rotating disk 2.

[0029] In this embodiment, the second drive unit 84 is a motor, which is fixedly mounted on the mounting frame 1. The motor shaft and the end of the transmission rod 81 are fixedly connected. Since the motor as a whole does not need to rotate with the rotating disk 2, the possibility of the cable connected to the motor being damaged during operation is reduced.

[0030] A pair of stop bars 21 are provided on the rotary disk 2, and the milling tool holder 3 is placed between the pair of stop bars 21. The milling tool holder 3 slides in cooperation with the stop bars 21 along the radial direction of the rotary disk 2. The stop bars 21 guide and limit the milling tool holder 3, reducing the possibility that the threaded rod 83 will drive the milling tool holder 3 to rotate synchronously during rotation. At the same time, as the milling tool holder 3 moves along the rotary disk 2, the stop bars 21 limit the milling tool holder 3, improving the stability and positional accuracy of the movement of the milling tool holder 3.

[0031] A mounting ring 711 is provided at one end of the rotating shaft 71 near the rotating disk 2. A transmission cylinder 716 is provided on the side wall of the mounting ring 711. The axial direction of the transmission cylinder 716 is parallel to the axial direction of the mounting ring 711. A first circular toothed ring 712 and a first bevel toothed ring 714 are coaxially provided on the cylinder wall of the transmission cylinder 716. A second circular toothed ring 713 that meshes with the first circular toothed ring 712 is coaxially provided at the end of the transmission rod 81. A second bevel toothed ring 715 that meshes with the first bevel toothed ring 714 is provided at the end of the threaded cylinder 82.

[0032] The mounting ring 711 is connected to the rotating disk 2 by bolts and threads. The large contact area between the mounting ring 711 and the rotating disk 2 improves the installation stability of the mounting ring 711 and the rotating disk 2. The rotating disk 2 has a placement groove 22 on the side near the mounting ring 711 for placing the first circular toothed ring 712, the second circular toothed ring 713, the first bevel toothed ring 714 and the second bevel toothed ring 715.

[0033] After the motor drives the transmission rod 81 to rotate, the transmission rod 81 drives the second circular gear ring 713 to rotate. The second circular gear ring 713 drives the transmission cylinder 716 to rotate through the first circular gear ring 712. The rotating transmission cylinder 716 drives the second bevel gear ring 715 to rotate, which in turn drives the first bevel gear ring 714 to rotate, thereby driving the threaded cylinder 82 to rotate.

[0034] The mounting frame 1 is equipped with a speed adjustment rod 9, which passes through the mounting frame 1 and rotates around its own axis in coordination with the mounting frame 1. A first gear ring assembly 91 is coaxially mounted on the speed adjustment rod 9, and a second gear ring assembly 717 is coaxially mounted on the outer wall of the rotating shaft 71. The first gear ring assembly 91 and the second gear ring assembly 717 mesh with each other, and the first drive unit and the speed adjustment rod 9 are in a transmission coordination. The first gear ring assembly 91 is movably mounted on the speed adjustment rod 9, and the second gear ring assembly 717 is movably mounted on the rotating shaft 71.

[0035] Both the first gear ring group 91 and the second gear ring group 717 include multiple gear teeth. By changing the relative positions of the first gear ring group 91 and the second gear ring group 717, the first gear ring group 91 and the second gear ring group 717 mesh with different gear ratios to further adjust the rotational speed of the rotating shaft 71. In this embodiment, the first drive unit is also a motor, which is fixed in a predetermined position and is driven by the speed adjustment lever 9 via a belt.

[0036] The implementation principle of a milling device for a beveling machine according to an embodiment of this application is as follows: When using this milling device to beveling the end of a pipe, the axes of the pipe and the rotating disk 2 are first aligned. Then, according to the diameter of the pipe, the milling cutter holder 3 is moved radially along the rotating disk 2 by the second drive source 8, so that the rotation diameter of the milling cutter is adapted to the diameter of the pipe. Next, the lead screw module 6 on the base 5 moves along the axial direction of the rotating disk 2, so that the milling cutter and the pipe come into contact. Afterwards, the first drive unit in the first drive source 7 drives the rotating shaft 71 to rotate, thereby driving the rotating disk 2 to rotate, causing the milling cutter to rotate, thereby beveling the pipe. When adjusting the position of the milling cutter holder 3, the motor of the second drive unit 84 drives the transmission rod 81 to rotate. The transmission rod 81, through transmission cooperation with the threaded cylinder 82, causes the threaded cylinder 82 to rotate. The threaded cylinder 82, through threaded connection with the threaded rod 83, drives the milling cutter holder 3 to slide radially on the rotating disk 2. Meanwhile, the stop bar 21 on the rotary disk 2 guides and limits the milling tool holder 3, ensuring the stability and positional accuracy of the milling tool holder 3's movement. Furthermore, through the meshing of the first gear ring group 91 on the speed adjustment lever 9 and the second gear ring group 717 on the rotary shaft 71, and the transmission cooperation between the first drive unit and the speed adjustment lever 9, the rotational speed of the rotary shaft 71 can be further adjusted to adapt to different processing requirements.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
