Abstract
Abstract A five axis profiler has swivel head assembly attached to a vertical slide. The swivel head assembly includes a support, a first rotary slide mounted upon the support for rotation about a first axis, a second rotary slide mounted upon the second rotary slide for rotation about a second axis which crosses the first axis intermediate the respective rear and front ends of the first and second rotary slides to define an acute angle, and a spindle head fixedly secured to the second rotary slide. The spindle head may be rotatably positioned by rotating the first rotary slide and may be tilted by simultaneously rotating the first and second rotary slides in opposite directions. Worm gear arrangements are provided for rotating the rotary slides.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
218 words
In a multi-axis machine tool having a movable vertical slide, the combination of: a first rotary slide mounted upon the vertical slide for rotation relative thereto about a first axis; a second rotary slide mounted upon the first rotary slide for rotation relative thereto about a second axis such that the first and second axes cross intermediate the respective rear and front ends of the first and second rotary slides to define an acute angle; a Spindle head adapted to hold a tool secured to the second rotary slide such that a tool held by the head is radially spaced from the first axis a distance greater than that of the periphery of the front end of the first rotary slide so as to minimize interference with workpieces; and means to independently rotate the first and second rotary slides about the first and second axes comprising: a first worm gear fixedly connected to the rear portion of the first rotary slide; a first worm mounted upon the vertical slide in fixed relationship thereto in meshing engagement with the first worm gear; a second worm gear fixedly connected to the front portion of the first rotary slide; and a second worm mounted upon the second rotary slide in fixed relationship thereto in meshing engagement with the second worm gear.
Claim 2
Dependent Claim

In a multi-axis machine tool having a movable vertical slide, the combination of: a first rotary slide mounted upon the vertical slide for rotation relative thereto about a first axis; a second rotary slide mounted upon the first rotary slide for rotation relative thereto about a second axis such that the first and second axes cross intermediate the respective rear and front ends of the first and second rotary slides to define an acute angle; a Spindle head adapted to hold a tool secured to the second rotary slide such that a tool held by the head is radially spaced from the first axis a distance greater than that of the periphery of the front end of the first rotary slide so as to minimize interference with workpieces; and means to independently rotate the first and second rotary slides about the first and second axes comprising: a first worm gear fixedly connected to the rear portion of the first rotary slide; a first worm mounted upon the vertical slide in fixed relationship thereto in meshing engagement with the first worm gear; a second worm gear fixedly connected to the front portion of the first rotary slide; and a second worm mounted upon the second rotary slide in fixed relationship thereto in meshing engagement with the second worm gear.
Claim 3
Dependent Claim
33 words
The combination of claim 1, further including: a support fixedly connected to the vertical slide for mounting the first rotary slide thereupon; and bearing means interconnecting the support and the first rotary slide.
Claim 4
Dependent Claim
16 words
The combination of claim 1, wherein the spindle head comprises: a motor for rotating the tool.
Claim 5
Dependent Claim
53 words
The combination of claim 1, wherein the rear portion of the first rotary slide generally defines a truncated right circular cylinder having an axis coincident with the first axis, and wherein the front portion of the first rotary slide generally defines a surface of revolution having an axis coincident with the second axis.
