Abstract

The invention discloses a radial revolving knife device for a multi-shaft box. A hollow spindle is arranged in the multi-shaft box. A numerical control radial revolving knife device is positioned and fixed to the corresponding position of a rear cover of the multi-shaft box and comprises a servo motor, a ball screw, a ball screw nut, a sliding sleeve and a pull rod. The rotation movement of the servo motor is changed into the linear movement of the pull rod through the ball screw and the ball screw nut. A hollow boring rod is fixed to the front end of the hollow spindle. The pull rod penetrates the hollow spindle and stretches into a hollow part of the hollow boring rod. The gear end of a rack is fixed to the front end of the pull rod. Two knife bin holes are machined in the front end of the hollow boring rod. Two cutter clamps are arranged in the knife bin holes in a sliding manner, and tooth blocks engaged with the rack are fixed to the middle portions of the cutter clamps. Boring cutters are fixed to the cutter clamps in a fine adjustment manner. According to the radial revolving knife device, machining of a spindle hole and scraping of the two end faces of the spindle hole can be conducted at the same time, and the high perpendicularity of the end faces of the spindle and the spindle hole is guaranteed. Meanwhile, one machine tool is omitted, one procedure is omitted, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a radial long knife device for a multi-axis box, in particular to a device in which only one of the main shafts in the multi-axis box needs a radial long knife. Background technique [0002] Multi-axis box is an efficient hole processing tool commonly used in combined machine tools. It transmits power from power components to each working spindle by arranging transmission gears according to a certain speed ratio, so that it can obtain the required speed and steering. In the machining of the engine body, it is required to process the multi-axis hole while scraping both ends of the main shaft hole, and the verticality of the two ends facing the main shaft hole has strict requirements. hole to improve processing efficiency, ②The second process uses the same positioning and clamping method as the first process, and selects the end face boring head to complete the end face of the turning spindle. Due to the secondary clamping of th...
