Description

Technical Field

[0001] This utility model relates to the field of chip removal processing technology, and more specifically, to a milling device for chip removal processing. Background Technology

[0002] Damage to metallic materials caused by the surrounding medium is called metal corrosion. Rusting is the most common form of corrosion. During corrosion, chemical or electrochemical multiphase reactions occur at the metal interface, causing the metal to enter an oxidized state. This significantly reduces the mechanical properties of the metallic material, such as strength, plasticity, and toughness; damages the geometry of metal components; increases wear between parts; deteriorates electrical and optical properties; and shortens the service life of equipment. However, due to the excellent properties of metals, they are widely used in industrial production. Metal parts are prone to wear and tear over long-term use, so they sometimes need to be replaced. Some parts are also prone to rusting due to improper storage, so descaling is often required before use.

[0003] A search revealed that patent application CN202210488885.9 discloses a milling cutter for chip removal, comprising a worktable and a base. A support rod is positioned above the worktable, and a moving component for controlling the movement of the support rod is located at the bottom of the support rod. An annular limiting plate is positioned at the top of the support rod, and multiple limiting frames are evenly distributed on the sides of the annular limiting plate. Two parallel support plates are arranged inside each limiting frame. Compared to existing technologies, this application adds an annular limiting plate with multiple limiting frames evenly distributed on its sides. A retractable grinding component is arranged inside each limiting frame, and these multiple grinding components are arranged in a ring. This allows for rust removal from the surface of metal parts passing through the annular limiting plate. The retractable grinding components allow for grinding and rust removal at different locations on the part during rotation, improving grinding efficiency. Two sets of clamping mechanisms are used to rotate and fix the part requiring rust removal and grinding. However, the following drawbacks still exist:

[0004] Existing technologies are convenient for chip removal of circular workpieces, but not convenient for rectangular workpieces, resulting in poor applicability and flexibility.

[0005] In the existing technology, the workpiece is clamped by the first spring and the limiting block. The clamping stability is poor. During the chip removal process, the workpiece is prone to shaking, which affects the chip removal effect.

[0006] Therefore, we have made improvements to this and proposed a milling device for chip removal. Utility Model Content

[0033] like Figure 1 and Figure 2As shown, in a preferred embodiment, based on the above method, the shifting mechanism 4 further includes two horizontal plates 401 symmetrically fixed to the lower end face of the mounting frame 1.

[0034] like Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, in a preferred embodiment, based on the above method, the rotating mechanism 19 further includes a third bearing 1901 fixed to the outer wall of the assembly frame 5. A connecting shaft 1902 is fixedly connected to the inner wall of the inner ring of the third bearing 1901. One end of the connecting shaft 1902 passes through the assembly frame 5 and is fixedly connected to a transmission gear 1903 that meshes with the gear ring 18. The other end of the connecting shaft 1902 is fixedly connected to a first pulley 1904. A fourth bearing 1905 is fixedly connected to the assembly frame 5. A transmission tube 1906 is fixedly connected to the inner wall of the inner ring of the fourth bearing 1905. One end of the transmission tube 1906 passes through the assembly frame 5. A second pulley 1907 is fixedly connected to the other end of the transmission tube 1906. The second pulley 1907 is connected to the first pulley 1904 via a synchronous belt 1908. A second splined shaft 1909 is slidably connected inside the transmission tube 1906. Both ends of plate 9 are rotatably connected to mating plates 1910, which are fixedly connected to mounting frame 1. A fourth motor 1911 is fixedly connected to one of the mating plates 1910. The drive end of the fourth motor 1911 is fixedly connected to the shaft end of the second spline shaft 1909. The fourth motor 1911 drives the second spline shaft 1909 to rotate. The rotation of the second spline shaft 1909 drives the transmission tube 1906 and the second pulley 1907 to rotate. The second pulley 1907 drives the first pulley 1904, the connecting shaft 1902 and the transmission gear 1903 to rotate through the synchronous belt 1908. The rotation of the transmission gear 1903 can drive the gear ring 18 and the rotating plate 9 to rotate. When processing a circular workpiece, it can make the circular workpiece rotate. When processing a rectangular workpiece, it is convenient to adjust the position of the rectangular workpiece, thus facilitating chip removal processing on different surfaces of the rectangular workpiece, making it more applicable and flexible.

[0035] like Figure 1 As shown, in a preferred embodiment, based on the above method, a rubber pad 20 is fixedly connected to the inner wall of the clamping plate 11, and the surface of the rubber pad 20 is provided with anti-slip texture; this improves the anti-slip effect and ensures the stability of the workpiece during processing.

[0036] like Figure 1 and Figure 7 As shown, in a preferred embodiment, based on the above method, the lower end face of the mounting frame 1 is symmetrical and fixedly connected to two base frames 21, and the lower end faces of the two base frames 21 are symmetrical and fixedly connected to two support feet; providing stable support for the entire device and ensuring the stability of the device during operation.

[0037] Specifically, when using the milling device for chip removal: When removing chips from a circular workpiece, one end of the workpiece is placed on the rotating plate 9 within the fixed assembly frame 5. Then, the second telescopic cylinder 17 drives the fixed plate 15 to move. The movement of the fixed plate 15 causes the first bearing 14 and the connecting head 13 to move. The movement of the connecting head 13 causes the connecting rod 12 to move. The movement of the connecting rod 12 causes the sliding column 10 to move, thereby causing the clamping plate 11 to move inward simultaneously, thus clamping the circular workpiece. Then, the first telescopic cylinder 7 drives the connecting block 8 and the assembly frame 5 connected to it to move, causing the rotating plate 9 to abut against the other end of the workpiece. Then, the other end of the workpiece... The workpiece is clamped, and then the first motor 302 drives the bidirectional screw 301 to rotate. The rotation of the bidirectional screw 301 causes the two connecting blocks 303 to move inward simultaneously, bringing the milling roller 307 into contact with the outer surface of the circular workpiece. Then, the second motor 3015 drives the first spline shaft 3014 to rotate. The rotation of the first spline shaft 3014 drives the rotating tube 3012 and the second bevel gear 3013 to rotate. The rotation of the second bevel gear 3013 drives the first bevel gear 309, the rotating rod 305, and the mounting post 306 to rotate, thereby rotating the milling roller 307. Simultaneously, the fourth motor 1911 drives the second spline shaft 1909 to rotate. The rotation of 1909 drives the transmission tube 1906 and the second pulley 1907 to rotate. The second pulley 1907 drives the first pulley 1904, the connecting shaft 1902 and the transmission gear 1903 to rotate through the synchronous belt 1908. The rotation of the transmission gear 1903 can drive the gear ring 18 and the rotating plate 9 to rotate. When processing a circular workpiece, the circular workpiece can be rotated. At the same time, the third motor 403 drives the threaded rod 402 to rotate. The rotation of the threaded rod 402 causes the shift block 404 to move, thereby driving the moving frame 2 to move, and then causing the rotating milling roller 307 to move, thereby performing comprehensive chip removal processing on the circular workpiece. When a rectangular workpiece needs to be processed, it is first clamped and fixed. Then, the first motor 302 drives the bidirectional screw 301 to rotate. The rotation of the bidirectional screw 301 causes the two connecting blocks 303 to move inward simultaneously, so that the milling roller 307 contacts both sides of the rectangular workpiece. Then, the milling roller 307 is driven to rotate. With the cooperation of the shifting mechanism 4, the two sides of the rectangular workpiece are de-chipped. Then, the milling roller 307 is moved outward, and the rotation mechanism 19 is started to adjust the position of the rectangular workpiece by flipping it over. Then, the milling roller 307 de-chips the remaining two sides. This makes it easier to de-chip both round and rectangular workpieces, and it is more flexible and applicable.

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
