Description

In the proposed safety device with a fugovochnogo machine used for focusing in the workpiece, in order to supply and hold over the chuck, rotary bar, hinged on the mobile along the table machine rails.

In FIG. 1 shows a perspective view adapted1, mounted on a machine tool; FIG. 2 is a perspective view of a bar that presses a workpiece to a table.

On the table of the planer, the ruler A is fastened (Fig. 1), equipped with a guide projection B, having a shape, for example, a dovetail, and extending along the entire length of the ruler-L. A slide C, equipped with a handle E and a hinge D in which rotary bar F is fixed, can be moved along guide projection B. Bar F with its lower face is removed from the surface of the machine table by an amount somewhat greater than the height of the layer removed from the object being processed.

The object to be processed is placed on the machine table and pressed with its back side to bar F. Then

worker, imposing on the bar N (Fig. 2) and the last clip; the object to be processed to the table, moves with the handle E of the slide C and the block F, which, in turn, moves the object to be processed on the table. The hands of the worker at the same time, placed one on the handle of the bar And, and the other on the handle E, removed from the chuck.

When processing long items, the bar F is folded to the side.

The subject of the patent.

A safety device for a jointing machine, characterized by the use of an emphasis on the object to be processed, in order to hold it over the chuck, - bar F, swivel on hinge D connected with slide C, moved by the handle E by working along the guides 5 of ruler A, which bar / v with its lower edge is removed from the table surface by an amount somewhat greater than the height of the layer removed from the object being processed.
