PURPOSE:To improve work efficiency in a feed device with a vibrative bed for a grinding machine or the like, by constituting the device such that one of the two slide tables is fixed and the other table can perform reciprocating motion. CONSTITUTION:If a rod 44 is advanced, a connecting pin 40 is also advanced to press a flange 34 of a slide table 28 to the front. Accordingly, the table 28 is advanced by accompanying a slide table 30 through a spring 52, adapted to a stopper 24 and fixed by pressing force of the pin 40. Under this condition, driving force of a motor 56 rotates a cam 60 to vibrate the table 30 by urging force of the coil spring 52. If the rod 44 is moved backward, the table 30 is similarly fixed to vibrate the table 28. In this constitution, a work is easily mounted and removed to enable the improvement of work efficiency. |
