detailed description

FIG. 1 schematically shows a drilling and milling device for a clutch sleeve according to an embodiment of the present invention. As shown in FIG. 1 , the drilling and milling device for the clutch sleeve includes a workbench 1 , an electrical control system and two sets of drilling and milling fixtures 2 on the workbench 1 . Two groups of drilling and milling fixtures 2 are arranged symmetrically on both sides of the central axis of the workbench 1 .

The bottom of the workbench 1 is provided with an electric rotating device, which drives the workbench 1 to rotate around its central axis. The drilling and milling fixture 2 is provided with a corner oil cylinder 21 , a pressing arm 22 and a fixture 23 . A substrate 11 is provided on the workbench 1 . The corner oil cylinder 21 is fixed on the base plate 11 . Specifically, the end of the cylinder body of the corner oil cylinder 21 is fixedly connected to the base plate 11 by screws. It is more firmly connected by screws. The piston 211 of the angle oil cylinder 21 is fixedly connected with the middle part of the pressing arm 22 . Both ends of the pressing arm 22 are respectively provided with clamps 23 for clamping the workpiece. The workbench 1 is provided with four positioning cores 12 for placing the workpiece 3 . The positioning core 12 enables the operator to accurately place the workpiece 3 on the table 1 . The four positioning cores 12 correspond to the four clamps 23 respectively. The workpiece 3 is sleeved on the positioning core 12 and clamped by the corresponding clamp 23 . The electric control system is respectively connected with the corner oil cylinder 21, the electric rotating device and the clamp 23. The electric control device controls the rotation of the workbench 1 through the electric rotating device. The electric control system drives the rotation of the clamp 23 by controlling the rotation of the piston 211 of the corner oil cylinder 21 .
