Double-head milling machine

Abstract

The invention belongs to a dedicated milling machine, and particularly relates to a double-head milling machine. The double-head milling machine is characterized by comprising a machine body, power heads, a transmission mechanism and a tool clamping apparatus; the left power head and the right power head are fixedly connected on a table face of the machine body and are oppositely arranged, and the center lines of the left power head and the right power head are on the same axis; the transmission mechanism is fixedly connected at a position, perpendicular to the central lines of the left power head and the right power head, on the table face of the machine body; the transmission mechanism is composed of ball screws and a guide rail sliding block, and the tool clamping apparatus is fixedly connected on the guide rail sliding block. The double-head milling machine has the beneficial effects that the rigidity is high, a tool can be quickly replaced, and a cam can be quickly clamped tightly. Due to the fact that the power heads are adjusted, the roughness of two faces of a workpiece after being milled can reach more than Ra 6.3, the perpendicularity of the two faces and a datum plane can reach 0.05 mm, the depth of parallelism of the two faces can reach below 0.05 mm, the accuracy of the machine tool is high, the rigidity of the machine tool is good, the tool can be quickly replaced and easy to adjust, and the efficiency is high due to the fact that two surfaces can be milled through one-time clamping.

Description

technical field [0001] The invention belongs to a special-purpose milling machine, in particular to a double-head milling machine for processing counterweight square iron in automobile shock absorbers. Background technique [0002] The counterweight square iron in the automobile shock absorber is made of cold-drawn section steel, which is sawn off according to the design size, and then its two axial end faces are processed. To process the two axial end faces of square iron, the fitter has always been used to mark the line, and then mill one plane after mounting it with a rocker milling machine. The main disadvantage of this method is that it is clamped twice, and the verticality and parallelism of the two end surfaces after processing cannot be guaranteed, and the efficiency is low. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a double-head milling machine with high rigidity and quick...
