Abstract
An indexing turret stop assembly for a machine tool to provide variable stop indications. The indexing turret stop is generally comprised of a base structure for providing a turret platform and a predetermined number of indexed positions of rotation, and a plurality of stop rod assemblies extending perpendicularly from the base structure and corresponding to the number of indexed positions of rotation. Each stop rod assembly provides sliding and rotational adjustment to vary the overall length of the assembly. A dial micrometer is provided in combination with the indexing turret stop to provide an indication of the proper stopping position.
Claims8
An indexing turret stop apparatus for a machine tool, comprising:
- base means including a turret platform and a predetermined number of indexed positions of rotation;
- and
- a plurality of stop rod assemblies varying in length and corresponding to the number of said indexed positions of rotation, each having first rod means mounted to said turret platform and extending perpendicularly therefrom for providing a coarse adjustment in the length of said stop rod assembly, a cylindrical sleeve member having a seat portion and slidably disposed on said first rod means generally at a first end of said sleeve member, second rod means generally received in a second end of said sleeve member for providing a fine adjustment in the length of said stop rod assembly, said second rod means including a screw portion threadingly connected to said seat portion of said sleeve member, and first manually adjustable set screw means for restricting the movement of said sleeve member with respect to said first rod means and second manually adjustable set screw means for restricting the movement of said second rod means with respect to said sleeve member.
An indexing turret stop apparatus for a machine tool having a headstock assembly carrying a work piece and a tool cutting carriage movable relative to said headstock assembly along a plurality of ways, comprising:
- (a) a base plate secured to said tool cutting carriage;
- (b) a turret platform movably secured to said base plate for rotational movement relative to said base plate;
- (c) an indexing plate, interposed between said base plate and said turret platform, having a plurality of indentations facing said turret platform;
- (d) a spring loaded ball catch screw mounted in said turret platform and cooperating with said indentations to provide a predetermined number of indexed positions of rotation;
- (e) a plurality of stop rod assemblies varying in length and corresponding to the number of said indexed positions of rotation, each having a first rod mounted in said turret platform and extending perpendicularly therefrom for providing a course adjustment in the length of said stop rod assembly, a cylindrical sleeve member having a threaded nut portion and slidbaly disposed on said first rod, a first set screw mounted on said sleeve member for restricting the relative movement of said sleeve member on said first rod, a second rod disposed at the other end of said sleeve member and received therein for providing a fine adjustment in the length of said stop rod assembly, a rod screw fixedly attached to said second rod for coupling said second rod to said threaded seat portion in said sleeve member and permitting rotational movement of said second rod with respect to said sleeve member, and a second set screw mounted on said sleeve member for restricting the rotational movement of said second rod with respect to said sleeve member;
- and
- (f) micrometer means, mounted to one of said ways, cooperating with a selected one of said stop rod assemblies to provide a stop indication for the movement of said tool cutting carriage toward said headstock assembly.
