Description

Technical Field

[0001] The invention relates to the technical field of milling machines, in particular to a giant tank surface milling machine. Background Art

[0002] Milling machine is a widely used machine tool. It can process planes (horizontal plane, vertical plane), grooves (keyway, T-slot, dovetail groove, etc.), toothed parts (gear, spline shaft, sprocket), spiral surface (thread, spiral groove) and various curved surfaces. In addition, it can also be used for rotating body surface, inner hole processing and cutting work. However, traditional milling machines are used to mill products of ordinary size. During milling, the workpiece is clamped by the fixture on the workbench. However, power plants and shipyards often need to use large tank container equipment, which can reach several meters in diameter and several meters or even more than ten meters in height. Such tank containers usually need to withstand strong pressure inside. Therefore, such tank containers are usually made of metal as a whole, including the annular tank body of the main part. The upper and lower ends of the tank body are fixedly connected by welding or other methods with upper and lower sealed ends. In this way, it is necessary to mill the connection surface of the connection position of the tank body or the end, but the overall appearance of such tank body or end cover is huge and heavy. The traditional milling equipment processing platform cannot accommodate it at all. The existing processing method usually involves building a working platform on the outside of the tank body, and then requiring workers to climb onto the working platform with milling equipment to process the upper edge of the tank body section by section. This processing requires constant disassembly and assembly of the milling equipment, and the workflow is complicated. In addition, it is difficult to keep the edge of the giant tank body processed section by section on a horizontal plane. In this way, it is difficult to ensure welding or assembly requirements when docking the giant tank body and its ends.

[0003] The cutting of giant tanks is often done by flame cutting and other methods. The surface of the tank is often rough, and the plane on the tank has large fluctuations, so it needs to be removed layer by layer during milling. Since it is necessary to ensure the flatness of the tank edge milling, the milling cutter needs to perform multiple milling from top to bottom along the horizontal plane. This also means that when milling the edge of the tank, the milling cutter head often has a large amount of idle stroke, which affects the milling efficiency of the giant tank.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1 of the present invention: Please refer to Figure 1-Figure 4The giant tank body plane milling machine is mainly used to process the tank body 03 with a diameter and height of several meters or even tens of meters. The giant tank body plane milling machine includes a working platform 01, a horizontal rotating disk 02 is installed in the middle of the working platform 01, the tank body 03 to be milled is fixedly installed on the upper part of the rotating disk 02, and the side of the tank body 03 is designed with a lifting frame 1 vertically fixed on the working platform 01. The rotating disk 02 can adopt a traditional bearing rotating structure, and a giant-sized large load-bearing bearing is specially customized at the lower part of the rotating disk 02, and then an internal gear structure is assembled on the inner side of the bearing. The upper plane of the rotating disk 02 where the tank body 03 is placed is fixed on the internal gear part, and then the internal gear and the upper plane of the rotating disk 02 are driven to rotate by the motor. The internal transmission structure of the rotating disk 02 is similar to the traditional automatic turntable structure, which will not be described in detail here. In the specific design, due to the huge volume of the rotating disk 02, a maintenance entrance that can enter the lower part of the rotating disk 02 can be designed on the side of the working platform 01.

[0035] In this patent, the lifting frame 1 is equipped with a lifting assembly 2, and the lifting assembly 2 controls the fixing assembly 3 to move vertically up and down along the lifting frame 1, and the fixing assembly 3 is equipped with a milling module 5. The fixing assembly 3 includes a placement plate 37 corresponding to the upper edge of the tank body 03, and the lower outer side of the placement plate 37 is fixedly equipped with an outer wall plate 32 corresponding to the outer wall surface of the tank body 03, and the lower inner side of the placement plate 37 is fixedly equipped with an inner wall plate 371 corresponding to the inner wall surface of the tank body 03. The inner side of the outer wall plate 32 is equipped with an arc clamping plate 34 that can be pushed by the clamping plate control block 31 and can move horizontally toward the outer wall surface of the tank body 03. The arc clamping plate 34 and the inner wall plate 371 are equipped with rollers 4 that rotate along the vertical axis along the arc surface array on one side of the wall surface of the tank body 03. The arc dimensions of the above parts need to correspond to the curvature of the tank body 03 to be processed. At the same time, the lifting component 2 can be assembled relative to the working platform 01 using an easily disassembled structure. When placing the tank body 03 to be milled and disassembling the tank body 03, for the convenience of operation, the lifting component 2 and the corresponding upper fixing component 3 and the milling module 5 can be disassembled accordingly.

[0036] During the design, the fixed component 3 is assembled with the lifting component 2 in a horizontal sliding manner, and the lifting component 2 controls the horizontal movement of the fixed component 3 through the horizontal control block 29. The milling module 5 includes a milling cutter 513 rotating along a vertical axis, the cutting surface of the milling cutter 513 is facing the upper edge of the tank body 03, and the milling cutter 513 is assembled and lifted vertically relative to the placement plate 37. The milling width of the milling cutter 513 needs to be greater than the thickness of the tank body 03, so as to ensure that the milling cutter 513 can complete the milling of the edge of the tank body 03.

[0037] After the above structure is assembled, the axis of the tank body 03 is vertical relative to the horizontal plane of the rotating disk 02. At this time, if the weight of the tank body 03 is sufficient, a fixed structure is not required. If the tank body 03 is small and the weight is insufficient, the tank body 03 can be welded to the upper end surface of the rotating disk 02 by means of rib plate welding. When the tank body 03 is milled, the horizontal control block 29 controls the fixed assembly 3 to move toward the outside of the tank body 03 as a whole, the rollers 4 of the side array of the inner wall plate 371 are elastically pressed against the inner wall surface of the tank body 03, the clamping plate control block 31 pushes the outer wall plate 32 to move horizontally toward the outer wall surface of the tank body 03, the rollers 4 of the side array of the outer wall plate 32 are elastically pressed against the outer wall surface of the tank body 03, the milling cutter 513 moves downward to mill the upper edge of the tank body 03, the rotating disk 02 drives the tank body 03 to rotate about its axis, and the milling cutter 513 completes the milling of the upper edge of the tank body 03.

[0038] In this patent, the giant tank body 03 is placed vertically on the rotating disk 02, and a rotating structure is designed at the lower part of the rotating disk 02, so that the rotating disk 02 can drive the tank body 03 to rotate about its axis, and the lifting component 2 on the working platform 01 can lift the fixing component 3 vertically, and the milling module 5 can be sent to the upper milling end face of the tank body 03 through the fixing component 3 for milling processing. The fixing component 3 is designed with a clamping structure, which can clamp and fix the tank body 03 of different thicknesses at the wall position. The fitting part of this clamping method is contacted by the roller 4, so that when the rotating disk 02 drives the tank body 03 to rotate about its axis, the fixing component 3 and the milling module 5 are partially fixed, and the milling cutter 513 of the milling module 5 partially completes the milling of the upper part of the tank body. This arc-shaped rolling wrapping method has a simple structure, and the volume of the milling module 5 is very small, which can greatly reduce the complexity of the equipment and reduce the equipment cost. Since the main position of the force bearing when the milling module 5 is working acts on the wall of the tank body 03, the external support force requirement is greatly reduced, so the lifting frame 1 and the lifting assembly 2 can be designed to be more compact and convenient for disassembly and assembly.

[0039] At the same time, when the device is working, since the tank body 03 is aligned with the lower part of the milling cutter 513 by rotating on its own axis, the giant tank body 03 does not need to be constantly disassembled and reinstalled for the milling module 5 during milling, and the milling speed is faster. The one-time cutting maintained in a fixed position can maximize the flatness of the milling.

[0040] Further, after the fixing assembly 3 rises to the upper end of the giant tank body 03, the inner wall plate 371 and the arc-shaped clamping plate 34 are driven by the horizontal control block 29 and the clamping plate control block 31 to clamp the tank body from the inside and outside of the tank body 03. This clamping and clamping inside and outside at the same time can clamp and fix tanks of different thicknesses. In the specific design, the arc-shaped clamping plate 34 can be made of elastic material to adapt to the slight curvature difference caused by different diameters during production. When the arc-shaped clamping plates 34 on both sides are fitted with the giant tank body 03, the clamping plate control block 31 and the horizontal control block 29 are closed. In the specific design, the horizontal control block 29 and the clamping plate control block 31 can also use a cylinder structure. In this way, even when the inner wall plate 371, the arc-shaped clamping plate 34 and the roller 4 are all made of rigid materials, the elastic clamping of the inner wall plate 371 and the arc-shaped clamping plate 34 on the inner and outer walls of the tank body 03 can be achieved.

[0041] In the specific design, such as Figure 3 , Figure 4 and Figure 5 As shown, the clamping plate control block 31 is fixedly connected with a push rod 33 through an output shaft, and the push rod 33 is movably mounted on the inner surface of the outer wall plate 32. The other end of the push rod 33 is fixedly mounted on the outer surface of the arc clamping plate 34. The arc clamping plate 34 is slidably positioned with the placement plate 37 through a slider 35 provided on the upper surface. Specifically, the slider 35 is slidably mounted on the inner surface of a slide groove 36, and the slide groove 36 is provided at the lower end of the placement plate 37. In the specific design, the slide groove 36 adopts a T-slot structure, and the upper end section of the slider 35 is enlarged, and can be embedded in the upper part of the slide groove 36, so that the arc clamping plate 34 can also be slidably positioned in multiple positions in the upper slide groove 36, so that the clamping plate control block 31 can facilitate the arc clamping plate 34 to be ejected as a whole along the track through the push rod 33.

[0042] In the specific design, such as Figure 1 and Figure 2As shown, the lifting assembly 2 includes a screw rod 25, which is vertically mounted in the lifting frame 1. The screw rod 25 is mounted with a U-shaped slider 26 through surface thread engagement. The U-shaped slider 26 is movably mounted in a U-shaped slide 27. A connecting plate 28 is fixedly mounted on the outer surface of the U-shaped slide 27. The lifting frame 1 includes two left and right U-shaped slides 27, in which the lifting assembly 2 is respectively mounted. A motor 21 is fixedly mounted on the outer surface of the right side of the lifting frame 1. The motor 21 is fixedly connected to a rotating shaft 22 through an output shaft. The rotating shaft 22 is movably mounted on the inner surface of the lifting frame 1. Two active bevel gears 23 are fixedly mounted on the outer surfaces of both ends of the rotating shaft 22. The active bevel gear 23 is mounted with two linked bevel gears 24 through engagement. The lower surface of the linked bevel gear 24 is fixedly connected with a screw rod 25. Two horizontal control blocks 29 are fixedly mounted on both sides of the outer surface of the connecting plate 28. The lifting assembly 2 on both sides is respectively mounted with the fixing assembly 3. The fixing assembly 3 can be conveniently moved up and down by the screw drive assembly of the screw rod 25 and the U-shaped slider 26. The fixing assembly 3 is clamped to the left and right ends of the wall of the tank body 03, respectively, so that the structure is more stable during milling.

[0043] In the specific design, such as Figure 1 , 2 and Figure 8 As shown, the fixed component 3 on the left is equipped with a milling module 5, the fixed component 3 on the right is equipped with a transmitting end 6 of a photoelectric module, and the front end of the fixed component 3 on the left is equipped with a receiving end 61. During operation, the edge to be milled in front of the milling cutter 513 blocks the light emitted from the transmitting end 6 to the receiving end 61. The rotating disk 02 of the giant tank plane milling machine is controlled by a running computer, and the photoelectric module is connected to the running computer data. When the photoelectric module detects that there is no tank to be milled in front of the milling cutter 513, the running computer controls the rotating disk 02 to speed up the movement.

[0044] The giant tank plane milling machine, by assembling the receiving end 61 and the transmitting end 6 of the photoelectric module part on the left and right fixed components 3 respectively, and at the same time, the detection part of the photoelectric module is in the forward position of the milling cutter 513. At this time, through the detection of the photoelectric module, when the upper edge of the tank 03 passes through the milling part, the rotation of the tank 03 can be accelerated, so that the milling idle part passes quickly, and when the upper part of the tank 03 that needs to be milled reaches the position of the milling cutter 513, the rotation speed of the tank is slowed down and normal milling is performed. In this way, the time of invalid idle milling is greatly reduced, thereby greatly improving the overall milling efficiency.

[0045] In the specific design, two groups of transmitting ends 6 and receiving ends 61 of the two-way photoelectric modules are respectively mounted on the fixed components 3 on the left and right sides. In this way, detection can be performed at two positions at the same time, ensuring the accuracy of milling detection.

[0046] like Figure 6 and Figure 7 As shown, the milling module 5 includes a stepper motor 51, which is fixedly mounted on the outer surface of the side bracket 52, and the side bracket 52 is fixedly mounted on the upper surface of the left placement plate 37. The stepper motor 51 is fixedly connected to a transmission shaft 53 through an output shaft, and the transmission shaft 53 is movably mounted on the left inner surface of the two side brackets 52, and a rotating rod 57 is movably mounted on the right inner surface of the two side brackets 52; the transmission shaft 53 and the rotating rod 57 are respectively fixedly mounted with a driving gear 58 and a rotating gear between the two side brackets 52, and a lifting gear plate 59 is meshed and installed between the driving gear 58 and the rotating gear, and a limit block 510 is arranged on both sides of the lifting gear plate 59, and the limit block 510 is movably mounted in the slide groove arranged on the inner side of the two side brackets 52. The design of the lifting gear plate 59 enables the milling cutter 513 part of the milling module 5 to accurately control the milling thickness alone. In this way, there is no need to use a lifting structure to control the up and down position of the milling cutter 513, making milling more accurate. The driving gear 58 provides lifting power, and the rotating gear is a passive positioning gear. The symmetrical design of the rotating gear and the driving gear 58 can make the lifting gear plate 59 run more stably.

[0047] In the specific design, a chassis 512 is fixedly mounted on the lower surface of the lifting gear plate 59 , a milling cutter motor 511 is fixedly mounted on the upper surface of the chassis 512 , a milling cutter 513 is arranged on the lower surface of the chassis 512 , and the milling cutter 513 is driven by the milling cutter motor 511 .
