C. Wickman Limited, Coventry, England Application April 13, 1951, Serial No. 220,905
Claims priority, application Great Britain April 28, 1950 2 Claims.
This invention relates to a tool-slide actuatin mechanism, for use on a multi-spindle automatic lathe or other machine, of the kind adapted to effect a rapid movement of the tool-slide from a rest position to the Work piece, a relatively slow feed movement while the tool is acting on the work piece, and a rapid return movement to the initial position.
The invention has for its object to provide a mechanism of the above kind in a simple and convenient form.
The invention comprises the combination of a slide-actuating rack, a pinion or quadrant in engagement with the rack, a pivoted arm, a lever pivoted on the arm, adjustable means interconnecting the lever and the pinion or quadrant, a toggle mechanism for actuating the arm, and cams for actuating the toggle mechanism and the secondary lever.
In the accompanying drawings:
Figure 1 is a side elevation of a mechanism embodying the invention.
Figures 2 and 3 are similar views to Figure 1 showing two other working positions of the mechanism.
Figure 4 is an end elevation of the mechanism.
Referring to the drawings, a tool-slide a has formed on or connected to it a rack b, and with the latter is engaged a pinion or quadrant c. On the latter is formed or secured an arm (1 to the outer end of which is pivotally attached a link e, and the other end of the link is adjustably connected to a lever f of bell crank or other convenient form. The connection between the link and lever is efiected by a pivot pin g which is securable in any desired position along a slot 71. in one arm of the lever, and is such that the amount of angular movement to be imparted to the quadrant c and thence the slide a can be varied as desired.
At the elbow of the lever f is pivotally mounted an arm 2 which at one end is pivotally connected to a fixed fulcrum y. The other arm of the lever is provided with a roller is which engages an actuating cam m formed in one side of a disc n on a driving shaft 0.
To the pivoted arm 2' is connected one end of one of a pair of toggle links 17, q, the opposite end of the other link being pivotally attached to another fixed fulcrum 1'. On the link q is mounted a roller 8 which is in engagement with a cam t on the opposite side of the disc n.
The arrangement is such that (starting from the rest position of the tool-slide as shown in Figure 1) the toggle-actuating cam 22 first straightens the toggle links into alignment with each other and moves the pivoted arm i into contact with a fixed stop u, and in so doing rapidly advances the tool slide a to a position adjacent to the work piece which may be carried by a r0- tary spindle 2). Subsequently the cam m rocks the lever f relatively to the primary lever and so imparts feed movement to the tool-slide as shown in Figure 3. Later the cams effect rapid return of the tool-slide to the initial position shown in Figure 1.
When it is required to actuate simultaneously a second tool-slide, mounted in a difierent position on the machine, the additional tool-slide is provided with a rack and pinion or quadrant similar to that of the first tool-slide, and the quadrant is connected by another link as e to the lever 1.
By this invention a mechanism for actuating one or a pair of tool-slides is provided in a simple and convenient form, and the load imposed on the cams while the tool is in action is reduced to a minimum.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
1. A tool-slide actuating mechanism comprising in combination with the tool slide, a rack on said tool slide, an angularly movable toothed member engaging said rack, a first arm pivoted at one end to a fixed anchorage, a two-armed lever pivoted at the junction of its arms on said \first arm, adjustable means interconnecting one end of said two-armed lever and said toothed member, a toggle mechanism connected at one end to said first arm and provided at its opposite end with a fixed anchorage, a cam arranged to act on said toggle mechanism for imparting rapid movement to said tool slide, and a second cam arranged to act on the end of said two-armed lever remote from said adjustable means for imparting relatively slow feed movement to said tool slide.
2. A tool-slide actuating mechanism as claimed in claim 1, in which the adjustable means interconnecting one end of the two-armed lever and the toothed member comprise another arm secured to said toothed member, and a link connected at one end to the last mentioned arm and adjustably connected at its opposite end to the corresponding end of said two-armed lever.
