A cover milling edge guiding and positioning device

Abstract

This utility model relates to the field of guiding and positioning technology, and discloses a guide and positioning device for milling edges of a cover. It includes a machine body with a clamping mechanism in the middle. The clamping mechanism clamps the workpiece to be processed. The clamping mechanism includes two oil boxes, both located in the middle of the machine body. Multiple fixing units are connected to the bottom of each oil box. A piston tube is fixedly connected inside each fixing unit. A piston rod is slidably connected to the inner wall of the piston tube, and a partition plate is slidably connected to the rear side of the piston tube. In this utility model, hydraulic oil in the oil box flows into the piston tube through the communication channel with the fixing unit under the pressure of the extrusion plate, pushing the piston rod. The piston rod of each independent fixing unit moves according to the contour of the workpiece to fit the outer wall. This mechanism can adjust the shape of the clamping surface according to the shape of the workpiece, solving the problems of high cost and difficulty in adapting to fast-paced production in traditional methods.
