Multi-shaft drilling-tapping machine tool

Abstract

A multi-shaft drilling-tapping machine tool comprises a base, a column frame, a power machine frame and a lifting balance weight device. A gear box and a servo motor are arranged at the top of the power machine frame. A universal joint component and a drilling rod component are arranged in the power machine frame. A motor support and a driving motor are arranged at the top of the column frame. The lower portion of the driving motor is connected with a rotating lead screw. The multi-shaft drilling-tapping machine tool is characterized in that a working feed power shaft extends out from the right side of the gear box and is connected with a worm through a working feed transmission gear, the worm is in transmission connection with a worm gear in a worm gear box which is arranged at the back side of the power machine frame, a hollow worm gear shaft is fixedly connected with the worm gear and is arranged outside the rotating lead screw in a sleeved mode, a lead screw nut on the rotating lead screw is fixedly connected with the bottom end of the worm gear shaft, the power machine frame can move up and down along with rotating of the lead screw nut, and the upper end of the rotating lead screw extends out from a plane bearing arranged on the bottom of the motor support and is connected with the driving motor through a coupler. According to the multi-shaft drilling-tapping machine tool, the servo motor can drive the drilling rod component to carry out working feed and rotating machining at the same time, energy is saved when the machine tool works, and cost is lowered.

Description

technical field [0001] The invention relates to the technical field of metal processing machine tools, in particular to a multi-axis drilling and tapping machine tool capable of both drilling and tapping. Background technique [0002] Traditional multi-axis drilling machines generally include a column frame installed on the base, a power frame that can slide up and down on the left side of the column frame, and a liftable counterweight device for balancing the gravity of the power frame on the right side of the column frame. The universal joint assembly and the drill pipe assembly in the frame, the main motor and transmission gear box on the top of the power frame, the motor bracket on the top of the column frame and the drive motor that drives the screw to rotate. Wherein the several rotating power shafts protruding from the bottom of the gear box are connected to the universal joint assembly, the universal joint assembly is connected to the drill pipe assembly, the drivin...

Problems solved by technology

However, since the rotation of the drill pipe assembly in the power frame of the above-mentioned multi-axis drilling machine is driven independently by the servo motor on the transmission gearbox, and the work of the drill pipe assembly is realized by the screw rod driving the power frame to slide up and down. The rod is independently driven by the servo motor on the top of the column frame. In this way, a machine tool needs to be equipped with two servo motors. When working, the two servo motors must work all the time, which consumes a lot of energy, and the price of the servo motor is much higher than that of ordinary motors. higher cost
