[0023] Example 1

[0024] like Figure 1-5 As shown, this utility model provides a lead screw surface processing device, including a processing table, a driving mechanism fixedly connected to the surface of the processing table, and a processing mechanism fixedly connected to the inner wall of the processing table. The driving mechanism includes a first motor 21, a first chuck 22 fixedly connected to one end of the shaft of the first motor 21, a workpiece 23 overlapping the surface of the first chuck 22, a second chuck 24 overlapping one end of the workpiece 23, an adjusting member 25 rotatably connected to one side of the second chuck 24, a first slider 26 fixedly connected to one side of the adjusting member 25, a first screw 27 threadedly connected to the inside of the first slider 26, a first slide rail 212 slidably connected to the inner wall of the first slider 26, an arc-shaped support member 210 overlapping the bottom of the workpiece 23, a guide rod 29 fixedly connected to the bottom of the arc-shaped support member 210, a support frame 28 overlapping the surface of the lower end of the guide rod 29, an adjusting screw 211 threadedly connected to the inside of the support frame 28, and the upper end of the adjusting screw 211 overlapping the surface of the support member 210.

After moving to a suitable position, the second chuck 24 is pushed, so that the first slider 26 slides along the first slide rail 212. The workpiece 23 is pushed to contact the first chuck 22. After the first chuck 22 and the second chuck 24 fix the workpiece 23, it is processed. When other tools are needed, the fourth screw 311 is loosened, and the tool holder 37 is rotated to adjust the angle of the tool holder 37 so that the tool to be used faces the workpiece 23. Then the fourth screw 311 is tightened to complete the replacement of the tool 38, making it easier to use.

[0026] Example 2

[0028] In this embodiment, after fixing, the adjusting screw 211 is rotated in the opposite direction to move the support 210 downward, and the first motor 21, the second motor 31 and the third motor 361 are started. The first motor 21 drives the workpiece 23 to rotate, and the second motor 31 drives the threaded rod 32 to rotate, so that the drive block 33 drives the mounting part 34 to move. At the same time, the second slider 35 slides along the second slide rail 312 to guide the mounting part 34, so that the mounting part 34 drives the processing tool 38 to move.

[0029] Example 3

[0030] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a second slider 35 is inserted into the interior of both ends of the mounting member 34, a second slide rail 312 is slidably connected inside the second slider 35, one side of the second slide rail 312 is fixedly connected to the surface of the mounting bracket 12, a feed assembly 36 is threadedly connected inside the mounting member 34, a tool holder 37 is rotatably connected inside the feed assembly 36, a machining tool 38 is inserted into the interior of the tool holder 37, a third screw 39 is threadedly connected inside the tool holder 37, and the end of the third screw 39 is connected to the machining tool 38. The surfaces of the cutting tool 38 abut against each other, and the surface of the tool holder 37 is fixedly connected to the limiting plate 310. The limiting plate 310 is internally threaded with a fourth screw 311. The end of the fourth screw 311 abuts against the surface of the mounting part 34. The feed assembly 36 includes a third motor 361. One end of the shaft of the third motor 361 is fixedly connected to a feed screw 362.

The surface of the third motor 361 is fixedly connected to the surface of the mounting part 34.

[0031] In this embodiment, the third motor 361 drives the feed screw 362 to move the connector 363, thereby causing the connector 363 to slide on the surface of the second slider 35, which in turn drives the machining tool 38 to approach the workpiece 23 and create threads on the surface of the workpiece 23.

[0032] The working principle of this lead screw surface processing device will be explained in detail below.

At the same time, the guide rod 29 slides along the inside of the support frame 28 to guide the support 210. After moving to the appropriate position, the second chuck 24 is pushed, causing the first slider 26 to slide along the first slide rail 212. The workpiece 23 is pushed to contact the first chuck 22, and then the first chuck 22 and the second chuck 24 fix the workpiece 23. After fixing, the adjusting screw 211 is rotated in the opposite direction to move the support 210 downward. The first motor 21, the second motor 31, and the third motor 361 are started. The first motor 21 drives the workpiece 23 to move downward. 3. Rotation: The second motor 31 drives the threaded rod 32 to rotate, causing the drive block 33 to move the mounting part 34. At the same time, the second slider 35 slides along the second slide rail 312 to guide the mounting part 34, causing the mounting part 34 to move the machining tool 38. Simultaneously, the third motor 361 drives the feed screw 362 to move the connecting part 363, causing the connecting part 363 to slide on the surface of the second slider 35, bringing the machining tool 38 closer to the workpiece 23 and creating threads on the surface of the workpiece 23. When other tools are needed, loosen the fourth screw 311 to rotate the tool holder 37, adjust the angle of the tool holder 37 so that the machining tool to be used faces the workpiece 23, and then tighten the fourth screw 311 to complete the replacement of the machining tool 38, making it easier to use.
