[0035] Reference Figure 2 and Figure 3The processing box 1 has a drive assembly for adjusting the distance on the left side. A horizontal plate 5 is fixedly connected to the top of the support column 4, and a second electric slide rail 6 is fixedly connected to the bottom of the horizontal plate 5. A second sliding block 7 is slidably connected to the outer wall of the second electric slide rail 6.

A sliding plate 12 is provided, with its outer wall slidably connected to the inner wall of the recessed box 11. A sliding column 14 can slide up and down on the bottom inner wall of the recessed box 11. The top of the sliding column 14 is fixedly connected to the sliding plate 12.

The second motor 17 is fixedly connected to the inner wall of the left front end of the machining box 1. A first lead screw 18 is fixedly connected to the output end of the second motor 17. A movable seat 25 is threadedly connected to the outer right ring of the first lead screw 18. When the first lead screw 18 rotates, the movable seat 25 can move left and right under the action of its thread. A drive pulley 19 is fixedly connected to the outer left ring of the first lead screw 18. A second lead screw 21 is rotatably connected inside the left rear end of the machining box 1.

A limit plate and bolt are located on the outer left ring of the second lead screw 21, allowing for manual adjustment. A belt 20 is provided between the driving pulley 19 and the driven pulley 22. The driving pulley 19 drives the belt 20 to rotate, which in turn causes the driven pulley 22 to rotate, realizing the synchronous rotation of the first lead screw 18 and the second lead screw 21. This ensures the stability of the moving seat 25 during left and right movement. Guide columns 24 are slidably connected through the interior of both the front and rear ends of the moving seat 25. The left side of the guide column 24 is fixedly connected to the inner wall of the processing box 1.

Connecting columns 26 are fixedly connected to both the front and rear ends of the right side of the moving seat 25. The right side of the connecting column 26 is fixedly connected to the left side of the support block 27, transmitting the movement of the moving seat 25 to the support block 27, thereby realizing the left and right position adjustment of the support block 27 and its metal shaft.

[0037] Reference Figure 4 and Figure 5A support block 27 is slidably connected to the inner wall of the bottom of the processing box 1. A clamping assembly of different sizes is fixed on the top of the support block 27. The clamping assembly includes a third motor 28, which is fixedly connected to the top of the support block 27. The third motor 28 serves as a power source, driving the drive gear 30 to rotate. A support disk 29 is fixedly connected to the right side of the support block 27. The output end of the third motor 28 is fixedly connected to the drive gear 30. A driven gear 32 is meshed with the outer wall of the drive gear 30, and the middle end of the driven gear 32 is rotatably connected to the outer wall of the right side of the support disk 29. The outer wall of the drive gear 30 meshes with the driven gear 32, and the middle end of the driven gear 32 is rotatably connected to the outer wall of the right side of the support disk 29 via bearings or other rotatable connection methods. When the drive gear... When the wheel 30 rotates, it drives the driven gear 32 to rotate. The support plate 29 has evenly distributed clamping plates 23 slidably connected inside. The driven gear 32 has evenly distributed arc-shaped grooves 33 inside. One end of the clamping plate 23 is fixedly connected to a limiting rod 31, and the outer ring of the limiting rod 31 is slidably connected to the arc-shaped groove 33. The clamping plate 23 is long and narrow, and one end of its outer wall is fixed to the limiting rod 31. The limiting rod 31 is short and narrow, and its outer ring slides with the arc-shaped groove 33 inside the driven gear 32. When the driven gear 32 rotates, the arc-shaped groove 33 drives the limiting rod 31 to move, so that the clamping plates 23 slide in opposite directions inside the support plate 29, realizing the clamping or loosening operation of metal shafts of different diameters, and adapting to the processing needs of metal shafts of various specifications.

[0038] Working principle: The metal shaft to be processed is placed in the clamping assembly on top of the support block 27. The third motor 28 is started, and the output end of the third motor 28 drives the drive gear 30 to rotate. The drive gear 30 meshes with the driven gear 32, causing the driven gear 32 to rotate. The arc-shaped groove 33 inside the driven gear 32 rotates with it. As the outer ring of the limiting rod 31 slides against the arc-shaped groove 33, the arc-shaped groove 33 drives the limiting rod 31 to move, thereby causing the clamping plate 23, which is fixedly connected to the limiting rod 31, to slide inside the support plate 29, realizing the processing of different... The clamping and fixing of the large and small metal shafts are performed. According to processing requirements, the second motor 17 on the left side of the processing box 1 is started. The output end of the second motor 17 drives the first lead screw 18 to rotate. The driving pulley 19 on the outer left side of the first lead screw 18 drives the driven pulley 22 on the outer side of the second lead screw 21 to rotate via the belt 20, causing the second lead screw 21 to rotate synchronously with the first lead screw 18. When the first lead screw 18 and the second lead screw 21 rotate, the connecting columns 26 at both ends of the right side of the moving seat 25 drive the support block 27 and the metal shaft fixed on it to rotate... The bottom inner wall of the processing box 1 slides to adjust the left and right position of the metal shaft. The second motor 17 stops moving. Alternatively, the first lead screw 18 can be rotated by rotating the second lead screw 21 for precise machining. The first electric slide rail 2 is started, which drives the first sliding block 3, support column 4, and horizontal plate 5 to move left and right as a whole, further adjusting the machining position. The second electric slide rail 6 at the bottom of the horizontal plate 5 is started, which causes the second sliding block 7 to drive the connecting plate 8, hydraulic cylinder 9, fixed plate 10, groove box 11 and other components to move back and forth at the bottom of the horizontal plate 5 to adjust to the appropriate front and back position. The hydraulic cylinder 9 is started, and the output end of the hydraulic cylinder 9 pushes the fixed plate 10, groove box 11 and other components to move downward, so that the first motor 16 at the bottom of the fixed plate 15 is close to the metal shaft. The first motor 16 is started, which drives the corresponding machining tool to machine the metal shaft. During the machining process, if machining resistance is encountered, the sliding column 14 slides on the bottom inner wall of the groove box 11, and the damping spring 13 plays a buffering role to protect the equipment and machining tool, while ensuring the stability of the machining.
