Abstract
Each guiding tube of the equipment provided to guide the different stock bars which can be machined in a given automatic lathe carries collars and a cap member. The collars and cap members of all the tubes of the equipment have the same outer diameter so that any one of these tubes can be secured by means of removable yoking beams on the semi-cylindrical seats of brackets rigidly fixed to one and the same prismatic canal which confers a great stiffness to the guiding tube fixed thereto. Owing to a pin on said cap members entering a bracket notch, bores of the collars and tube mounted in said canal automatically come to lie opposite openings of oil supply conduits to control the pusher feeding the bar to the lathe and to form an oil cushion around that bar.
Claims10
A device for guiding the various workpiece bars which can be machined in an automatic lathe, comprising:
- at least two interchangeable guidance tubes of different diameters, each being alignable with the lathe headstock spindle to support that part of a workpiece bar which extends to the rear of the lathe;
- fastening members disposed at at least three points distributed along the guidance tubes for rigidly connecting the tubes to a reinforcing element extending along the entire length of the tubes.
