Numerically controlled milling machine with thread mill

摘要

The present invention relates to a numerically controlled milling machine having a screw thread, and more particularly, to a table operated in all directions, in front, rear, left, and right directions, to fix a workpiece to be screwed so as not to rotate, and in a vertical direction. The lower side of the head, which is operated up and down, is provided with a screw that is extrapolated loosely to the outside of the work piece, so that the screw can be machined on the outer periphery of the work piece formed in the form of a round bar having a steel wire or the like provided at the distal end thereof.;In the numerically controlled milling machine equipped with a screw factory value according to the present invention, the front and rear guide rails 2 are installed on both upper sides of the base body 1, and the left and right guide rails 5 are disposed on the upper and rear guide rails 2, respectively. And a forward and backward movement table 3 reciprocating forward and backward by the forward and backward movement motor 4, and the left and right guide rails 5 of the forward and backward movement table 3 are moved left and right by a left and right movement motor 6. A moving left and right moving table 7 is installed, and a lifting head 10 that is moved up and down by a vertical movement motor 9 is installed in front of the vertical body 8 installed vertically at the rear of the base body 1. The lifting head 10 has a vertical motor 22 mounted thereon with a cutter mounted vertically to fix a workpiece fixed to a vise seated on the left and right moving table 7 according to a signal of a numerical control controller. Numbers that can be processed in three dimensions In the air milling machine, the lower side of the elevating head 10 is provided with a screw machine mounting base 13 fixed with a rotary tube mounting portion 14 in a horizontal direction, and the predetermined position of the elevating head 10 is fixed. The power transmission means is installed, the inner side of the rotary tube mounting portion 14, the cutter 15 is installed detachably in the front two or three places so that the installation position is adjustable, the power from the power transmission means on the outer end of the rear end Tube-shaped rotary tube 17 is installed to be freely rotated with the bearing 18 interposed therebetween, and the rod-shaped workpiece is provided on one side of the left and right moving table 7. The clamp 11 for clamping is fixed, and the tailstock 12 supporting the distal end of the workpiece is fixedly installed on the other side of the left and right moving table 7.
