Technical Field

[0001] This utility model relates to the field of precision metal processing technology, and in particular to a micro-lubricated high-speed milling device for stainless steel tubes. Background Technology

[0002] With the development of demand for lightweight structural components in the aerospace manufacturing field, high-precision contour forming and surface integrity control of thin-walled stainless steel tubes are required in the manufacturing process of high-performance engine piping systems.

The mechanism employs a parallelogram linkage system formed by the main and auxiliary support rods to enable the first, second, and third limiting plates to move synchronously, dynamically adapting to the clamping requirements of stainless steel pipes with different outer diameters. This mechanical linkage design ensures that the central axes of the three limiting devices are strictly coincident and avoids the positioning deviation caused by traditional manual adjustment, significantly improving clamping efficiency and repeatability.

[0017] This invention utilizes a structure in which the second servo motor inside the connecting seat drives the wheel to rotate synchronously with the stainless steel tube, thereby generating a precise transmission cutting effect.

Combined with the adjustable fourth limit wheel for axial positioning, a closed-loop dimension control system is formed. This solution eliminates the influence of transmission clearance on machining accuracy through the rigid connection between the power source and the actuator, ensuring that the metal removal rate remains stable even under micro-lubrication conditions.

[0021] Example: Please combine Figure 1-6 This embodiment of a high-speed micro-lubricated milling device for stainless steel pipes includes a mounting assembly 1. The mounting assembly 1 includes a support frame 101, a mounting frame 102 fixedly connected to the outer surface of the support frame 101, a first servo motor 103 fixedly connected to the outer surface of the mounting frame 102, a drive screw 104 fixedly connected to the output end of the first servo motor 103, the drive screw 104 rotatably connected to the inside of a fixed base 105, and a main support rod 106 rotatably connected to the inside of the fixed base 105.

The fourth limiting wheel 405 is disposed on the outer surface of the stainless steel tube 307.

[0022] The outer surface of the drive screw 104 is threadedly connected to an adjusting seat 107, and the inner surface of the adjusting seat 107 is rotatably connected to a secondary support rod 108, which is rotatably connected to the outer surface of the main support rod 106.

[0023] As the drive screw 104 rotates, it causes the adjusting seat 107 to slide. At this time, the distance between the adjusting seat 107 and the fixed seat 105 can be adjusted. The adjusting seat 107 and the fixed seat 105 are connected to the main support rod 106 through the auxiliary support rod 108. As the adjusting seat 107 moves, it can drive the first limiting plate 201, the second limiting plate 301 and the third limiting plate 401 to be adjusted, so as to clamp stainless steel tubes 307 of different sizes.

[0024] The first limiting plate 201 is rotatably connected to the inside of the first limiting plate 202, and the outer surface of the first limiting plate 201 is fixedly connected to the connecting plate 203. The outer surface of the connecting plate 203 is fixedly connected to the placement rack 204, and the outer surface of the placement rack 204 is fixedly connected to the mounting block 205.

[0025] A milling plate 206 is rotatably connected inside the mounting block 205. The milling plate 206 is set on the outer surface of the stainless steel tube 307. A lubricating oil rack 207 is fixedly connected inside the placement frame 204. The lubricating oil rack 207 is set on top of the milling plate 206.

[0026] The milling blade 206, which is connected to the outer surface of the first limiting plate 201 via the mounting block 205, can be used to mill the stainless steel tube 307.

[0027] The second limiting plate 301 is rotatably connected to the second limiting wheel 302, and the outer surface of the second limiting plate 301 is fixedly connected to the limiting rod 303, which is slidably installed inside the mounting bracket 102.

[0028] A connecting seat 304 is fixedly connected to the outer surface of the limiting rod 303. A second servo motor 305 is fixedly connected inside the connecting seat 304. A drive wheel 306 is fixedly connected to the output end of the second servo motor 305. The drive wheel 306 is located on the outer surface of the stainless steel tube 307.

[0029] The third limiting plate 401 is rotatably connected to a third limiting wheel 402. The outer surface of the third limiting plate 401 is fixedly connected to a limiting block 403. The limiting block 403 is slidably installed inside the mounting frame 102. The outer surface of the third limiting plate 401 is fixedly connected to a limiting frame 404.

[0030] Stainless steel tubes 307 are sleeved on the outer surfaces of the first limiting plate 201, the second limiting plate 301, and the third limiting plate 401.

[0031] Driven by the second servo motor 305 inside the connecting seat 304, the drive wheel 306 is rotated. Since the drive wheel 306 is matched with the stainless steel tube 307, it can be ensured that the stainless steel tube 307 rotates under the limit of the first limit wheel 202, the second limit wheel 302, the third limit wheel 402 and the limit frame 404.

[0032] The implementation principle of the micro-lubricated high-speed milling device for stainless steel pipes in this embodiment is as follows: Driven by the first servo motor 103, the drive screw 104 rotates within the fixed seat 105. As the drive screw 104 rotates, the adjusting seat 107 slides, allowing adjustment of the distance between the adjusting seat 107 and the fixed seat 105. The adjusting seat 107 and the fixed seat 105 are connected to the main support rod 106 via a secondary support rod 108. With the movement of the adjusting seat 107, the first limiting plate 201, the second limiting plate 301, and the third limiting plate 401 are adjusted, thereby clamping stainless steel pipes 307 of different sizes. When clamping the stainless steel pipe 307, the first limiting plate 201, the second limiting plate 301, and the third limiting plate 401 within the connecting seat 304... The drive of the two servo motors 305 drives the drive wheel 306 to rotate. Since the drive wheel 306 is matched with the stainless steel tube 307, it can ensure that the stainless steel tube 307 rotates under the limit of the first limit wheel 202, the second limit wheel 302, the third limit wheel 402 and the limit frame 404. At this time, the milling blade 206 connected to the outer surface of the first limit plate 201 through the mounting block 205 can perform milling on the stainless steel tube 307. When the first limit plate 201, the second limit plate 301 and the third limit plate 401 are adjusted, the positions of the milling blade 206, the second servo motor 305 and the fourth limit wheel 405 can be adjusted simultaneously to ensure that stainless steel tubes 307 of different sizes are always clamped, fixed and processed.
