Description: |
| Abstract:
The present invention relates to an improved tool slide mechanism for machine tools, and particularly that type of machine tool which includes a rotatable carrier, haying one or more rotary work tables, and one or more tool slide mechanisms related to the work tables, and adapted to move into and out of relation to the work; and to operate automatically thereon; it being understood, however, that the invention is not limited to such use, but may be employed upon a machine having a single work table and a single tool slide mechanism to cooperate therewith. An object of the invention is to provide tool slides respectively adapted to have independent movement imparted thereto from a single source of power. in which the application of such power will be positive, direct, and free of sliding or other parts which might set up variable working relations and forces between the tool slides, and particularly in which a given speed, force and cutting resistance upon one of the slides will not effect a given speed, force and cutting resistance upon the other slide; and further to provide for the independent adjustment of the slide relatively to the work, to the end that the machine may be adapted to work upon pieces of different dimensions and of various shapes. A further object is to provide means whereby the relative extent and speed of the slides may be adjusted and regulated, as desired, and in which a maximum variation as to speed, extent. force and cutting resistance may be provided upon each of the slides without effecting the operation of the other slide, or the characteristics of the work to to be performed thereby. A still further object is to provide means whereby the slides may be reciprocated in either direction relative to each other, that is, one slide may be made either to move to the right or the left during the movement of the other slide in one direction, or in either direction during the movement in the other direction.
Claim:
In a tool slide mechanism, a support. a tool slide mounted to reciprocate vertically, a second tool slide mounted to reciprocate horizontally, a reciprocating rack member, a gear meshing with and adapted to be rotated by said rack member and having a spindle, a pair' of gears, one for each slide, mounted on said spindle and connected to be o driven thereby, gearing between said pair of gears and the respective tool slides, and means whereby said gears may be disconnected to permit adjustment of said slides independently of said rack member ouch of each other. |
