High-speed feeding transmission mechanism for ram type milling head for numerical control machine tool

Abstract

The invention discloses a high-speed feeding transmission mechanism for a ram type milling head for a numerical control machine tool. A base is included. The two sides of the side wall of the base arefixedly connected with stand columns. The opposite side walls of the stand columns are rotationally connected with a reciprocating lead screw, and the reciprocating lead screw is in threaded connection with a screw nut. The side wall of the screw nut is fixedly connected with a ram through a connecting rod, and the side wall of the ram is fixedly connected with the milling head. Through the arrangement of a first drive mechanism, a liquid pumping mechanism, a pushing mechanism, a first transmission mechanism, a second transmission mechanism and a second drive mechanism, a motor can be used for driving the reciprocating lead screw to rotate so that the ram feeding motion can be finished, and compared with a traditional feeding mechanism, more stability is achieved; meanwhile, the motor further synchronously drives a sliding plug to reciprocate, accordingly, cooling liquid is sprayed to the surfaces of the milling head and a milling tool, the milling head cooling and temperature reduction function is achieved, the producing and machining cost is saved, meanwhile, synchronous actions with the ram can be conducted, and deformation caused by the tool high milling head temperature due to untimely cooling is avoided.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a high-speed feed transmission mechanism of a ram type milling head for a numerical control machine tool.

AI Technical Summary

Problems solved by technology

[0004] The high-speed feed transmission mechanism of the ram-type milling head used in the CNC machine tool in the prior art still has certain deficiencies, the ram cannot reciprocate very stably; and the milling head is working because the milling cutter is constantly cutting The workpiece, so the milling head will generate extremely high temperature. In the prior art, the milling head is generally sprayed with cooling liquid through a separate water cooling mechanism to reduce its temperature. This cooling method requires a separate power mechanism, not only Increased production and processing costs, and the separate water-cooling mechanism cannot synchronize with the ram, which will easily lead to untimely cooling, resulting in deformation of the milling head due to excessive temperature
