[0005]为了解决上述背景技术中提出的卧式加工过程中金属碎屑易缠绕于铣刀的表面，此时随着铣刀的移动，缠绕的金属碎屑容易对金属件的表面形成划痕，进而导致金属件加工后的美观性降低，不利于推广使用的问题，本申请提供一种管状金属件表面车铣设备
[0012] 1. By setting a milling cutter, the tubular metal part is placed vertically on the top side of the hollow tray. Turning the double-acting screw causes two support columns to move relative to each other simultaneously. At the same time, the double-acting screw drives a gear to rotate, which in turn drives two toothed plates to move relative to each other. These two toothed plates then drive two other support columns to move outwards. All four support columns can move outwards simultaneously until they contact the inner wall of the placed tubular metal part, achieving compression and limiting. The motor's output shaft drives a worm gear to rotate, which in turn drives a worm wheel to rotate. The worm wheel then drives a rotating rod and a reciprocating screw to rotate. The rotating rod, in conjunction with the hollow tray, drives the placed tubular metal part to rotate. The reciprocating screw, in conjunction with the connecting sleeve, drives the milling cutter to move up and down reciprocally. During this up-and-down movement, the milling cutter can perform milling operations on the surface of the rotating tubular part in a standing position. The milling chips, under the influence of gravity, will fall directly off the milling cutter, thus preventing metal chips from entangled and scratching the surface of the metal part. This ensures the aesthetic appearance of the machined metal part and facilitates its widespread use.

Technical Field
[0001] This application relates to the technical field of milling and turning of parts, and in particular to a milling and turning device for the surface of tubular metal parts. Background Technology
[0002] Turning, milling, planing, and grinding are the four basic machining methods in mechanical processing. They are important parts in parts manufacturing, mainly used to process parts so that they can be used for the assembly of machinery and equipment. These include turning, milling, planing, and grinding. Different parts require different machining methods. For example, shaft parts generally only require turning, while some parts require two or more of these methods to complete their machining.
[0003] However, in practical applications, most existing milling and turning equipment typically uses a horizontal machining method when milling and turning tubular metal parts. However, during horizontal machining, metal chips tend to get tangled on the surface of the milling cutter. As the milling cutter moves, the tangled metal chips can easily scratch the surface of the metal part, which reduces the aesthetics of the machined metal part and hinders its widespread use.
[0004] Therefore, those skilled in the art have provided a milling and turning device for the surface of tubular metal parts to solve the problems mentioned in the background art. Utility Model Content

[0011] In summary, this application includes the following beneficial technical effects:
[0012] 1. By setting a milling cutter, the tubular metal part is placed vertically on the top side of the hollow tray. Turning the double-acting screw causes two support columns to move relative to each other simultaneously. At the same time, the double-acting screw drives a gear to rotate, which in turn drives two toothed plates to move relative to each other. These two toothed plates then drive two other support columns to move outwards. All four support columns can move outwards simultaneously until they contact the inner wall of the placed tubular metal part, achieving compression and limiting. The motor's output shaft drives a worm gear to rotate, which in turn drives a worm wheel to rotate. The worm wheel then drives a rotating rod and a reciprocating screw to rotate. The rotating rod, in conjunction with the hollow tray, drives the placed tubular metal part to rotate. The reciprocating screw, in conjunction with the connecting sleeve, drives the milling cutter to move up and down reciprocally. During this up-and-down movement, the milling cutter can perform milling operations on the surface of the rotating tubular part in a standing position. The milling chips, under the influence of gravity, will fall directly off the milling cutter, thus preventing metal chips from entangled and scratching the surface of the metal part. This ensures the aesthetic appearance of the machined metal part and facilitates its widespread use.

Detailed Implementation
[0018] The following will be combined with the appendix Figure 1-3 The technical solution of this utility model has been clearly and completely described. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0019] This application discloses a milling and turning device for the surface of a tubular metal part, referring to... Figure 1-3The system includes a processing table 1, a hollow tray 2 rotatably connected to the top side of the processing table 1, four sliding grooves on the top side of the hollow tray 2, and support columns 3 slidably connected to the inner walls of each of the four sliding grooves. A double-acting screw 4 is rotatably connected to the outer side of the processing table 1. Two of the four support columns 3 are helically driven and sleeved with the double-acting screw 4. A gear 5 is fixedly sleeved on the outer side of the double-acting screw 4. Two toothed plates 6 are meshed and connected to the outer side of the gear 5. The two support columns 3 are respectively fixedly connected to the two toothed plates 6. A rotating rod 7 is fixedly connected to the bottom side of the tray 2, and a reciprocating lead screw 8 is rotatably connected to the top side of the processing table 1. A connecting sleeve 9 is helically driven on the outer side of the reciprocating lead screw 8, and a milling cutter 10 is slidably connected to the inner wall of the connecting sleeve 9. A motor 11 is fixedly connected to the bottom side of the processing table 1, and a worm gear 12 is fixedly connected to the output shaft of the motor 11. Worm wheels 13 are fixedly sleeved on the outer sides of both the rotating rod 7 and the reciprocating lead screw 8, and both worm wheels 13 are meshed with the worm gear 12. By setting the milling cutter 10, the tubular metal part is placed vertically on the hollow tray. On the top side of the disc 2, the double-acting lead screw 4 is turned. When the double-acting lead screw 4 rotates, it drives the two support columns 3 to move relative to each other simultaneously. At the same time, the double-acting lead screw 4 drives the gear 5 to rotate, and the gear 5 drives the two toothed plates 6 to move relative to each other. The two toothed plates 6 drive the other two support columns 3 to move outward respectively. At this time, the four support columns 3 can move outward simultaneously until they contact the inner wall of the placed tubular metal part to achieve compression and limiting. The output shaft of the motor 11 drives the worm gear 12 to rotate, the worm gear 12 drives the worm wheel 13 to rotate, and the worm wheel 13 drives the rotating rod 7 and the reciprocating lead screw 8 to rotate. The rotating rod 7, together with the hollow disc 2, drives the placed tubular metal part to rotate. The reciprocating lead screw 8, together with the connecting sleeve 9, drives the milling cutter 10 to move up and down reciprocally. During the up and down reciprocating movement of the milling cutter 10, the surface of the rotating tubular part can be milled in a standing position. At this time, the milling chips will fall directly from the milling cutter 10 due to the influence of gravity, thereby avoiding the metal chips from getting entangled and causing scratches on the surface of the metal part, thus ensuring the aesthetics of the metal part after processing, which is conducive to its widespread use.
[0020] In this application, a limiting plate 14 is fixedly connected to the top side of the processing table 1, and the connecting sleeve 9 is slidably connected to the left side of the limiting plate 14. By setting the limiting plate 14, when the connecting sleeve 9 drives the milling cutter 10 to move up and down, the limiting plate 14 can limit the movement of the connecting sleeve 9, so as to avoid the connecting sleeve 9 and the reciprocating lead screw 8 from rotating together.
[0021] In this application, a threaded hole is provided on the top side of the connecting sleeve 9, and a limit bolt 15 is threadedly connected to the inner wall of the threaded hole. By setting the limit bolt 15, when performing milling operations on the surface of tubular metal parts of different sizes, the milling cutter 10 can be moved and adjusted inside the connecting sleeve 9. After the adjustment is completed, the limit bolt 15 is tightened to fix the position of the adjusted milling cutter 10, thereby improving the applicability of the milling cutter 10 and reducing its limitations.
[0022] In this application, threaded holes are provided on the top side of each of the four support columns 3, and screws 16 are threadedly connected to the inner walls of each of the four threaded holes. Pressure plates 17 are rotatably sleeved on the outer sides of each of the four screws 16. By setting pressure plates 17, when the tubular metal part is placed on the hollow tray 2, the screws 16 are turned, and the screws 16 drive the pressure plates 17 to move downward. At this time, the pressure plates 17 can squeeze and fix the placed tubular metal part from the top side, thereby further improving the stability of the tubular metal part.
[0023] In this application, the top side of the processing table 1 is provided with multiple roller grooves, and the inner walls of the multiple roller grooves are movably installed with ball bearings 18; by setting the ball bearings 18, the multiple ball bearings 18 cooperate with each other to support the hollow tray 2 from the bottom side, while minimizing the friction.
[0024] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
[0025] The implementation principle of the surface milling equipment for tubular metal parts in this application embodiment is as follows: During use, the tubular metal part is placed vertically on the top side of the hollow tray 2. The double-acting screw 4 is turned, causing the two support columns 3 to move relative to each other simultaneously. At the same time, the double-acting screw 4 drives the gear 5 to rotate, which in turn drives the two toothed plates 6 to move relative to each other. The two toothed plates 6 then drive the other two support columns 3 to move outwards. At this time, all four support columns 3 can move outwards simultaneously until they contact the inner wall of the placed tubular metal part to achieve compression and limiting. The output shaft of the motor 11 drives the worm gear 12 to rotate, which in turn drives the worm wheel 13 to rotate. The worm wheel 13 drives the rotating rod 7 and the reciprocating screw 8 to rotate. The rotating rod 7, in conjunction with the hollow tray 2, drives the placed tubular metal part to rotate. The reciprocating screw 8, in conjunction with the connecting sleeve 9, drives the milling cutter 10 to move up and down reciprocally. During the up-and-down reciprocating movement of the milling cutter 10, the surface of the rotating tubular part can be milled in a standing position. At this time, the milled debris, affected by gravity, will directly fall from the milling cutter 10. The screw 10 moves up and down, preventing metal chips from getting tangled and scratching the surface of the metal parts, thus ensuring the aesthetics of the processed metal parts and facilitating its widespread use. When the connecting sleeve 9 drives the milling cutter 10 to move up and down, the limiting plate 14 can limit the movement of the connecting sleeve 9, preventing the connecting sleeve 9 from rotating with the reciprocating lead screw 8. When milling the surface of tubular metal parts of different sizes, the milling cutter 10 can move and adjust inside the connecting sleeve 9. After adjustment, the limiting bolt 15 is tightened to fix the position of the adjusted milling cutter 10, thereby improving the applicability of the milling cutter 10 and reducing its limitations. When the tubular metal part is placed on the hollow tray 2, the screw 16 is tightened, and the screw 16 drives the pressure plate 17 to move downward. At this time, the pressure plate 17 can squeeze and fix the placed tubular metal part from the top side, thereby further improving the stability of the tubular metal part. Multiple balls 18 cooperate to support the hollow tray 2 from the bottom side, while minimizing friction.
[0026] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships.
