Description

Technical Field

[0001] This utility model relates to the field of spinning technology, and in particular to a spinning device for CNC lathes. Background Technology

[0002] Spin forming technology, as a highly efficient and energy-saving plastic forming process, is widely used in the machining of high-precision rotating parts (such as conical parts, cylindrical parts, parabolic shells, etc.) in aerospace, automotive manufacturing, and military industries. Traditional CNC lathe spinning devices typically employ a single spinning wheel structure, applying radial or axial pressure to the rotating workpiece through the spinning wheel to achieve continuous localized plastic deformation of the material.

[0003] However, existing technologies have the following significant drawbacks: limited precision; during a single spinning process, the material is prone to springback due to stress release, making it difficult to meet high requirements for workpiece dimensional accuracy and geometric tolerances, especially for thin-walled parts or high-strength materials. High-precision workpieces often require secondary fine spinning to eliminate deformation errors, but traditional devices require disassembling the first-stage spinning wheel, replacing it with a finishing spinning wheel, and resetting the tool. Replacing the spinning wheel increases auxiliary time, resulting in low processing efficiency. Utility Model Content

[0024] The following is combined with Figures 1 to 3 This invention describes a spinning device for a CNC lathe according to an embodiment of the present invention.

[0025] A spinning device for a CNC lathe includes a mounting plate 1, a first rotating part 2, a second rotating part 3, a first mounting member 4, a second mounting member 5, a first spinning wheel 6, a second spinning wheel 7, and a tool holder 8. The first rotating part 2 is mounted on one end of the mounting plate 1, and the first mounting member 4 is mounted on the rotating end of the first rotating part 2, with the first mounting member 4 rotating through the first rotating part 2. The first spinning wheel 6 is mounted on the swinging end of the first mounting member 4, and the first mounting member 4 can drive the first spinning wheel 6 to swing up and down. The second rotating part 3 is mounted on the other end of the mounting plate 1, and the second mounting member 5 is mounted on the rotating end of the second rotating part 3, with the second mounting member 5 rotating through the second rotating part 3. The second spinning wheel 7 is mounted on one side of the upper end of the second mounting member 5, and the tool holder 8 is mounted on the other side of the upper end of the second mounting member 5.

[0026] A spinning device for CNC lathes is installed at the tool mounting position to shape the workpiece. It can be installed at the tool mounting position of a horizontal CNC lathe, model CAK6140. The tool mounting section of the CNC lathe moves the mounting plate 1, causing a first spinning roller 6 to press against the workpiece. The first spinning roller 6 is mounted on the swing end of a first mounting member 4. Depending on the height of the workpiece, the first mounting member 4 can move the first spinning roller 6 up and down, applying pressure to the workpiece and deforming it, completing the first shaping. The tool mounting section of the CNC lathe moves the mounting plate 1, causing a second spinning roller 7 to press against the workpiece. The second mounting member 5 is positioned at the height of the second spinning roller 7 according to the height of the workpiece. The second spinning roller 7 applies pressure to the workpiece, deforming it and completing the second shaping, resulting in high workpiece shaping accuracy.

[0027] The first rotating part 2 is mounted on one end of the mounting plate 1, and the second rotating part 3 is mounted on the other end of the mounting plate 1. When the first spinning roller 6 is close to the workpiece for processing, the second spinning roller 7 is away from the workpiece. When the second spinning roller 7 is close to the workpiece for processing, the first spinning roller 6 is away from the workpiece.

[0028] The first mounting part 4 is mounted on the rotating end of the first rotating part 2. The first mounting part 4 rotates through the first rotating part 2. The rotation here refers to the first rotating part 2 driving the first mounting part 4 to rotate in the horizontal plane, which facilitates the adjustment of the angle of the first spinning wheel 6 relative to the workpiece, and facilitates the first spinning wheel 6 to process the workpiece.

[0029] The second mounting member 5 rotates through the second rotating part 3. The rotation here refers to the second rotating part 3 driving the second mounting member 5 to rotate in the horizontal plane, which facilitates the adjustment of the angle of the second mounting member 5 relative to the workpiece and facilitates the processing of the workpiece by the second mounting member 5.

[0030] The tool holder 8 is installed on the other side of the upper end of the second mounting part 5. The tool holder 8 can cut the workpiece and can cut the parts of the workpiece that do not need to be cut.

[0031] The first spinning wheel 6 and the second spinning wheel 7 can be arc wheels. The tool holder 8 can be a one-piece tool holder.

[0032] Specifically, the first mounting component 4 includes a mounting shaft 401, a swing block 402, a pneumatic telescopic cylinder 403, a rotating block 404, and a connecting block 405. The mounting shaft 401 is mounted on the upper end of the first rotating part 2, with one end of the mounting shaft 401 protruding from one side of the first rotating part 2. One end of the swing block 402 is rotatably mounted on the side of the mounting shaft 401 protruding from the first rotating part 2, and the other end of the swing block 402 is arc-shaped. One end of the connecting block 405 is fixedly mounted on the arc-shaped end of the swing block 402, and the first spinning wheel 6 is rotatably mounted on the other end of the connecting block 405. The pneumatic telescopic cylinder 403 is rotatably mounted on the top of the first rotating part 2, and the rotating block 404 is rotatably mounted on the upper end of the swing block 402. The driving end of the pneumatic telescopic cylinder 403 is rotatably connected to the rotating block 404, and the extension and retraction of the pneumatic telescopic cylinder 403 drives the swing block 402 to swing up and down through the rotating block 404. The other end of the swing block 402 is arc-shaped. The pneumatic telescopic cylinder 403 can extend and retract to drive the swing block 402 to swing up and down, which facilitates the adjustment of the position of the first spinning wheel 6 installed at the swing block 402 to process the workpiece. The pneumatic telescopic cylinder 403 can be of model SC32X25.

[0033] To further explain, the oscillating block 402 has two connecting blocks 405 at one of its arc-shaped ends. The two connecting blocks 405 are respectively installed at the upper and lower ends of the oscillating block 402, and each of the two connecting blocks 405 is equipped with a first spinning wheel 6. The diameters of the two first spinning wheels 6 can be designed to be one large and one small, and the first spinning wheel 6 is selected for processing according to the diameter of the workpiece.

[0034] To further explain, a top block 9 is provided on one side of the top of the first rotating part 2, and the pneumatic telescopic cylinder 403 is rotatably mounted on the top block 9. The top block 9 facilitates the installation of the pneumatic telescopic cylinder 403.

[0035] Specifically, the first rotating part 2 includes a first column 201 and a base plate 202. The first column 201 is detachably mounted on the top of the base plate 202. First elongated holes 203 are respectively provided on both sides of the lower end of the first column 201. The first elongated holes 203 are arc-shaped. The base plate 202 is provided with first fixing holes. Bolts are inserted through the first elongated holes 203 and the first fixing holes to fix the first column 201 to the base plate 202. The arc-shaped first elongated holes 203 facilitate the alignment of the first fixing holes with the positions of the first elongated holes 203 after the first column 201 is adjusted and rotated. Since the first column 201 is mounted on the top of the base plate 202, the first fixing holes are not shown in the attached drawings.

[0036] To further explain, the base plate 202 is also provided with a second fixing hole 204, and the mounting plate 1 is provided with a second elongated hole 10. Bolts are inserted into the second fixing hole 204 and the second elongated hole 10 to fix the base plate 202 to the mounting plate 1. The position of the base plate 202 on the mounting plate 1 can be adjusted according to usage requirements.

[0037] Specifically, the second rotating part 3 includes a servo motor 301, a worm gear 302, a worm wheel 303, and a housing 304. The worm gear 302 is mounted on the drive end of the servo motor 301, and the bottom of the first mounting member 4 is mounted on the worm wheel 303. The worm gear 302 and the worm wheel 303 are connected in a transmission manner. The servo motor 301 drives the worm gear 302 and the worm wheel 303 to rotate, causing the first mounting member 4 to rotate. The housing 304 is sleeved and mounted on the outside of the worm gear 302 and the worm wheel 303. The servo motor 301 drives the worm gear 302 to rotate, causing the worm wheel 303 to drive the first mounting member 4 to rotate horizontally. This facilitates adjusting the angle of the second spinning wheel 7 toward the workpiece and switching the tool holder 8 toward the workpiece for cutting, thus facilitating processing. The transmission between the worm gear 302 and the worm wheel 303 is stable.

[0038] Specifically, the second mounting component 5 includes a second column 501, a first connecting rod 502, and a second connecting rod 503. The second column 501 is rotatably mounted on the housing 304, with its lower end connected to the worm gear 303. The first connecting rod 502 and the second connecting rod 503 are respectively mounted on the two side walls of the second column 501. The second spinning wheel 7 is rotatably mounted on the upper end of the first connecting rod 502. The tool holder 8 is mounted on the upper end of the second connecting rod 503. The first connecting rod 502 and the second connecting rod 503 facilitate the installation of the second spinning wheel 7 and the tool holder 8. The first connecting rod 502 and the second connecting rod 503 are respectively mounted on the two side walls of the second column 501. When the second spinning wheel 7 faces the workpiece, the tool holder 8 is positioned away from the workpiece, preventing them from interfering with each other.
