Milling machine for wrench opening

Abstract

The invention discloses a milling machine for a wrench opening. The milling machine comprises a transmission device, a fixing frame, a hydraulic cylinder, a wrench fixture and a work bench, wherein the transmission device comprises a motor and a knife shaft; the motor and the knife shaft are respectively fixed on the fixing frame through a bearing; the motor is transmittedly connected with one end of the knife shaft; the other end of the knife shaft is fixedly connected with an alloy milling cutter; the side wall of the fixing frame and the side wall of the work bench are slidingly connected by a sliding table; the hydraulic cylinder is disposed below the fixing frame; the wrench fixture is disposed in front of the milling cutter; the fixture comprises a pedestal, a support, a hydraulic piston disposed in the support and the fixing plate disposed on the top of the support; the hydraulic piston and the support are disposed at the top of the pedestal; a piston rod of the hydraulic piston penetrates through the fixing plate and protrudes out of the support; the top of the piston rod of the hydraulic piston is provided with a press block; the top surface of the fixing plate is provided with a lug; and the lug and the milling cutter form an included angle. The wrench opening milled by the machine is flat in surface, good in quality, high in work efficiency and convenient for use.

Description

technical field [0001] The invention relates to a wrench milling machine. Background technique [0002] At present, in the milling machine for milling the wrench, the milling tool holder and the transmission device generally move laterally, and the workpiece fixture that fixes the wrench body is also horizontally clamping the wrench body, and the milling cutter passage is reserved horizontally. Since the workpiece fixture clamps the wrench body horizontally, the way the milling cutter mills the wrench opening in the working process of the milling machine adopts horizontal milling, and the traverse device for performing horizontal milling does not run smoothly. , The wrench is easy to loosen and shift, resulting in the flatness of the surface of the wrench opening not meeting the requirements, poor quality, resulting in low production efficiency, low economic benefits, and inconvenient use. Contents of the invention [0003] The purpose of the present invention is to provi...
