United States Patent AUTOMATIC, SELF-ADJUSTING WIRE WELD FILER Peter Joseph Rumsavich, Chicago, Ill.
Application March 16, 1953, Serial No. 342,558
1 Claim. (Cl. 90-15) This invention is an automatic, self-adjusting, wire weld filer, that requires no die changes, adjusts itself to any size wire, and does work in seconds, that requires minutes in manual labor.
The invention is illustrated in the accompanying drawings in which, Fig. 1, is a cut-away side view of the entire gear assembly, showing position of gears with relation to the housing, the internal ring gear 8, that transmits power thru successive gears to the cutting blades. This gear ring is cast into the housing, which comes in two sections, a right and let t housing, bolted together at the center to form the sleeve mounting for the main gear assembly as shown in Figs. 2, 5, and 11 at 5. By spreading the right and left housing apart the entire gear assembly may be removed without disturbing any part therein. Fig. 1 also illustrates how expansion of the rocker arms 19, 20 is accomplished by means of a stop 23, that is part of the housing, said step causing the arms 19, 20, Fig. 1, to recede into the recessed portions of the main gear 4, at lines 35, 36.
Fig. 2 is a cut-away front view of the same assembly showing the method of mounting the working parts onto the main gear and how the gears are spaced. It shows how the main gear fits into the sleeve mounting at and how the rocker arms 19, straddle the main gear 4. The electrically controlled clamps 18, move up and down freely in the guides 30, 31. These guides are cast into the frame, and finally the anvil part of the clamps 32, 33, which centers the work vertically are incorporated into the housing.
Fig. 3 is a top view of the upper rocker arm, one of the two which carry the cutting blades. This upper rocker arm has one side extended which comes into contact with the stop 23, Fig. 1. It shows how the cutting blade is mounted into the arm, and how it is driven by gear and gear chain. It shows the construction at line 24, so that these arms straddle the main gear 4, and tinally mounting of the pressure springs at 21.
Fig. 4 is a front view of both the upper and lower rocker arms to illustrate how the rocker arm frame at 27, 28 serves as a guide to control the depth or shallowness of the surface to be cut.
Fig. 5 is a detail drawing of the method of mounting the main gear 4 (upper half) in the housing that provides the sleeve for the gear to rotate in, without a center shaft. On the left at 7 is the drive gear for the cutting blades, on the right at 34 is the stabilizing gear that reduces wear to a minimum in the sleeve mounting.
Fig. 6 illustrates how expansion of the lower rocker arm is accomplished vthru gear teeth 25, 26, which are cast into the arm. Pressure when in operation is supplied by suitable springs 21, 22.
Fig. 7 is the complete upper and lower rocker arm assembly in operating position showing all gears and gear chains.
Fig. 8 shows the design of gear 4, with a radial slot to permit insertion of work, and the recessed portions at 2,755,708 Patented July 24, 1956 'ice I 35, 36, which allow the cutting heads to recede far enough to insert work.
Fig. 9 illustrates the housing and how it is machined with a radial slot to permit insertion of work at line 1, and how it is constructed without a recessed portion at line 2, so that it centers the work horizontally.
Fig. 10 is a cut-away sectional view in a line 10, 10, in Fig. 9, to clarify the centering of work vertically by the anvil parts of the clamps 32, 33. This figure also shows the mounting of the motor with gear 3 at 29.
Fig. 11 is a sectional view in a line 11, 11, Fig. 9, to show how the anvil parts of the clamps are incorporated in the housing at 32, 33. It also shows in detail how the extension on the upper rocker arm 19 comes in contact with the stop 23, which is a part of the housing 6.
A complete cycle of this machine is as follows: when work is inserted into the opening at line 1, Figs. 1 and 9, which is a radial slot machined in the main gear 4, Fig. 1, as well as the two housing sections, Fig. 9, to the point at line 2, Figs. 1 and 9, and power is applied, three distinct operations begin. First, the electrically controlled clamps 18, Figs. 2, 10, bear down on the work to hold it rigid and in place. Second, gear 3, Figs. 1, 10, begins to rotate in a clockwise direction causing the main gear assembly 4 to rotate in a counterclockwise direction thru the sleeve mounting 5, Figs. 2 and 5. At this instant gear 7, Fig. 1, begins to rotate by virtue of its being geared to the internal gear rings 8, Figs. 1 and 11, which is stationary and part of the housing 6. This gear 7 transmits power thru gears 9, 10, 11, dual integral or change gears, gear chains 12, 13, and gears 14, 15 to the cutting blades 16, 17, Figs. 1, 3, 4, 7, causing the blades to spin and cut any surface that is in contact with it. At the instant that this second operation begins, the third operation begins simultaneously; as the main gear assembly 4, Fig. 1, moves in a counterclockwise direction the rocker arms 19, 20, which are mounted on this gear assembly leave the stop 23, that is stationary and attached to the housing, by virtue of the downward motion of this gear assembly 4; as this upper rocker arm 19 leaves stop 23, pressure springs 21,
22, Fig. 6, tend to force the cutting heads onto the work to be processed, and come to rest as shown in Fig. 7. Trimming the periphery of the work piece is done as long as the main gear assembly is in motion, this operation continues in a counterclockwise direction until a point is reached where the lower cutting blade has overlapped the cut, started by the upper cutting blade, to insure a clean cut, then the power is reversed automatically at gear 3, Fig. 1, and the main gear assembly 4 rotates in a clockwise direction until it comes to rest at the reset position as shown in Fig. 1. This distance of travel of the main gear assembly 4, Fig. 1, is adjustable to insure a uniform cut.
Pressure springs that tend to force the cutting heads down onto the work as shown in Fig. 7 are mounted directly opposite gears 10, 11, Fig. 7, as indicated at line 21, Figs. 3, 11. The rocker arms operate free of their respective shafts to avoid any chattering at the cutting blades.
You will notice from Fig. 1 that only the one side of the upper arm is extended to come in contact with the stop 23. To expand this arm, to accomplish expansion of the lower arm gear teeth .are cast into the upper and lower rocker arms, as shown in Fig. 6, at 25, 26. These gear teeth expand the lower arm simultaneously with the upper arm, and also provide uniform pressure on both arms when in operation. These rocker arms are both cast with a center space as shown at line 24, Fig. 3, so that they straddle the main gear 4, Figs. 2, 11.
The self-adjusting theory is carried out in the following manner: when the rocker arms come to rest onto the Work as shown in Fig. 4, the cutting blades 16, 17 will cut only to the extent of the cutting guides 27, 28 coming to rest onto the work. Regardless of the diameter of the Work, this permits any size Work to be filed, .without any die changes or adjustments and also controls the shallowness or depth of the cut Whichever is needed.
All gears mounted on the main gear 4, Fig. 1, operate free of their respective shafts, with the exception of gears 14, 15, Fig. 7, which are keyed to their respective shafts with the cutting blades 16, 17, Figs. 3, 4. This is done to reduce chattering to a minimum.
Backlash by the spring pressure is taken up at the motor 29, Fig. 10, which is automatically braked when at rest.
I claim:
A machine tool combination for peripherally trimming a metal workpiece comprising a frame, a rotatably driven tool carriage and a work support means mounted on said frame, means on said carriage for s-wingably supporting at least two rotary metal working tools, means responsive to the rotational movement of said carriage for driving said tools, means on said carriage normally biasing said second mentioned support means to a position wherein said tools engage the workpiece and gauge means on said second mentioned support means operatively engaging the workpiece for controlling the depth of cut made by said tools.
