[0001] The invention relates to the technical field of mechanical processing, in particular to a machine reamer rotating device used for mechanical processing. Background Art

[0002] A reamer is a tool with multiple sharp cutting edges. It is mainly used for finishing or semi-finishing existing holes in workpieces to remove a small amount of metal material, making the inner wall of the hole smoother and the size more accurate, and can improve the position accuracy of the hole. It is widely used in industrial fields such as automobile manufacturing, aerospace, and mold processing.

[0015] Working principle: When the device is needed, first place the workpiece to be processed on the upper surface of the placement table, then turn on the second hydraulic cylinder fixed to the outer wall of the support frame, and the output end of the second hydraulic cylinder can push the slider to slide on the outer wall of the fixed column through the clamping plate, and the slider can push the rotating shaft fixed by the transmission plate to rotate through the connecting sleeve when moving, and then the transmission plate can pull the slider at the other end of the fixed column through the connecting sleeve at the other end to slide relative to each other, thereby driving the clamping plates at both ends to move, so as to clamp and fix the workpiece on the upper surface of the placement table, ensuring the accurate position of the workpiece during processing and enhancing the processing efficiency. The working stability is improved. At the same time, the technician can rotate the workpiece to drive the placement table to rotate on the end of the support column, and then clamp it to achieve multi-faceted processing of the workpiece, thereby improving the flexibility of the device. After that, the first motor is turned on, and the output end of the first motor can drive the screw rod to rotate on the inner wall of the fixed frame.

After that, the sleeve is driven to rotate by turning on the third motor, and then the first hydraulic cylinder is turned on, and its output end drives the positioning frame to slide on the upper surface of the support plate to drive the reamer body to process different positions of the workpiece. When the reamer body is replaced, the bolts on the inner wall of the sleeve are rotated, and the bolts can be adjusted by The guide plate is driven to slide on the outer wall of the guide rail through a threaded connection with the fixed block, and when the guide plate moves, the second gear can be driven to rotate through the second rack, and when the second gear rotates, the guide plate at the other end can be driven to move relatively through the meshing connection, thereby driving the guide plate to clamp or loosen the reamer body handle in the installation groove. At the same time, the two layers of guide plates are perpendicular to the clamped or loosened positions of the reamer body, thereby more effectively ensuring the stability of the reamer body during rotation, thereby achieving more effective installation and disassembly of the reamer body, facilitating the maintenance and replacement of the reamer body, and improving the processing adaptability and production continuity.
