Description

Technical Field

[0001] This application relates to the technical field of rotating shaft processing, and more specifically, to a rotating shaft grinding and polishing device. Background Art

[0002] A rotating shaft generally refers to a part or device that rotates around its own axis. In the fields of engineering and manufacturing, rotating shafts have various applications and designs. Rotating shafts can be used for rotating components in mechanical devices, such as the crankshaft in an engine, the bearing shaft in turbomachinery, etc. These shafts are usually used to transmit power or support rotating components. During processing, the rotating shaft can be used as the support center for clamping the workpiece to ensure that the workpiece rotates around the axis for processing operations such as drilling, grinding, and polishing. The rotating shaft in an electric motor or engine is the core part that converts electrical energy into mechanical energy and drives the rotational movement of other mechanical components. In scientific instruments and precision equipment, rotating shafts are used to ensure precise rotation and positioning, such as the rotating mechanisms in optical instruments like microscopes and telescopes. The design of rotating shafts takes into account factors such as material strength, precision requirements, rotational speed, and working environment. In manufacturing and engineering applications, it is crucial to ensure the balance, wear resistance, and long-term stability of rotating shafts.

[0003] After retrieval, in the Chinese utility model patent application publication number: CN202322227479.X, a rotating shaft grinding and polishing device is disclosed. By setting the output shaft of the first motor to drive the gear to rotate, the gear drives the rack to move, and the rack drives the first positioning block to move through the first fixing block, so that both ends of the rotating shaft are in contact with the rotating shafts on the first positioning block, and the bottom of the rotating shaft contacts the third positioning block, achieving the effect that the rotating shaft can be clamped and the whole rotating shaft can be ground and polished at one time. However, the type of the grinding stone on the grinding block is the same as the required rotating shaft to be ground, so it can only grind and polish rotating shafts of the same type. When the rotating shaft is long, it is impossible to grind and polish the whole of it, and the applicable range is small. Utility Model Content

The second rotating plate 206 is rotatably connected to the first rotating plate 205. By starting the first motor 203, the output end of the first motor 203 drives the first rotating shaft 204 to rotate. The first rotating shaft 204 drives the first rotating plate 205 to rotate. The first rotating plate 205 drives the second rotating plate 206 to rotate. The second rotating plate 206 drives the slider 201 to slide on the slide rail 202, and finally drives the grinding block 4 to move, enabling the grinding and polishing of rotating shafts of different lengths, thus expanding the scope of application;

[0024] A support plate 5 is fixedly connected to the side of the slider 202 close to the grinding block 4. A cylinder 6 is fixedly connected to the bottom of the support plate 5. The grinding block 4 is fixedly connected to the telescopic end of the cylinder 6. By starting the cylinder 6, the telescopic end of the cylinder 6 drives the grinding block 4 to descend, so that the grinding block 4 contacts the surface of the rotating shaft, and grinding and polishing are carried out through the rotating rotating shaft;

[0025] A fixing mechanism 3 is arranged on the workbench 1. The fixing mechanism 3 includes fixing seats 301. There are two fixing seats 301, and both of the two fixing seats 301 are fixedly connected to the top of the workbench 1.

Fixing cylinders 306 are fixedly connected to the outside of both of the two sliding blocks 305. The two fixing cylinders 306 are symmetrically arranged left and right. By bringing one end of the rotating shaft into contact with the second rotating shaft 7 in the fixing cylinder 306, and then starting the second motor 302, the output end of the second motor 302 drives the bidirectional lead screw 303 to rotate. Under the limitation of the limiting rod 304, the two sliding blocks 305 approach each other, thereby driving the two fixing cylinders 306 to approach each other, so that both ends of the rotating shaft are abutted against the second rotating shaft 7 to fix the rotating shaft;
