Description

In the proposed device, the box with the adjustable frame with the wedge protrusions interacting with the same protrusions on the board carrying the workpiece, in order to install this board and the workpiece is in the required position relative to the board which is placed in the slide, moved along the box in its upper part.

In FIG. 1 shows a longitudinal section of the device; FIG. 2 - the same, top view; FIG. 3 is the same in section along the line I - in FIG. 2; FIG. 4- a perspective view of the plow; FIG. 5, a perspective view of a portion of the sled; FIG. 6- top view of the sled; FIG. 7-side view of the plow, placed in a sled; FIG. 8 is a plan view of the board carrying the workpiece support.

The proposed fixture consists of an oblong box A without a bottom and a lid (Fig. 1-3), to the long side walls of which, on the inside of the box in its lower part, are guides B. On the guides B there is a frame B, fitted with wedge projections -G . Frame B is filled with the adjustable part along the guides B with the help of the handle L attached to it,

(287)

the handle D for fixing a certain position of the frame B is fixed by a wedge E in the slot made in the front short wall of box A. Above the frame B in box 4 is placed a LAN board freely movable inside box A in height and fitted from its bottom sides with wedge lugs 3 that rest on the lugs / frames B.

A fixed stop M is attached to the back short side of the box, below its upper edge. To the long side walls of the box, there are guide strips -K attached to the outer side, between which is placed board M, carrying a second stop (Fig. 8), which is adjustable with board M along box A. In board M, a cutout is made for a wedge B, which, when driven into the cutout of board M, serves to clamp the board between the planks b. The slats 1C serve simultaneously as guides for the O- / 7 sled (Fig. 5), designed to support the plow T and are made in the form of a frame of O bars laid on the edge and P bars laid flat. The width of the OP slide is equal to the distance between the slats, while the length of the inner part thereof is equal to the length of the supporting part of the plane T. The slide of the OP in the lower part for

facilitating their movement can be provided with rabbits Y (Fig. 5). Plow T for ease of installation in the slide is provided on its block with projections P and C (Fig. 4, 7).

The board intended for processing is placed on a board G, which is raised or lowered depending on the required thickness of the board being processed; FIG. Figure 1 shows the lowest position of the plank Ж and in order to raise it, it is necessary to pull frame B out of the handle to the right according to the drawing. Then the wedge lugs D attached to frame B, moving together with the frame, will lift the wedge lugs 3, and with them the board J. For a smooth course of the board W it is pulled by springs or rubber W The board F is raised in the raised position wedge E, respectively, moved by handle X. By installing board w, the front end of the board to be machined rests against the stop, and from the other end is pressed with a adjustable stop L, the board L / of which is wedged by the wedge H between planks K. of box A. Then onto the upper edge longitudinal walls of the box A ki between the guide strips mounted slide O- K / 7 placed therein plow T and is moved along the slide boards treated periodically moving transversely to the slide plane T. In this case, the plow T produces processing

the board and makes its thickness accordingly made the installation board J.

The subject matter of the invention.

Claims (3)

1. A device for correctly handing boards off boards, characterized by the use of box A (Fig. 1-3), with guides B below, for adjustable using a handle} and a wedge E of frame B with wedge projections P interacting with similar projections 3 on the board W, for the purpose of its height setting, which board W serves to place on it the board under treatment, fixed between the stops, fixed L4 and the adjustable board L (Fig. 8), and processed by the Strug T (Fig. 4) supported by the O- / Z slide (Fig. 6), moved along the upper sides boxes A provided with guide plates K. 2. In the device according to claim 1, use of the plow T, fitted on the block with projections P and C in order to mount it on the O-slide and move along with it, which slide to facilitate them. movements can be equipped with rollers Y (Fig. 5). 3. In the device according to claim 1, use for clamping a treated board of a relocatable b, ortham box L of an L-M stop (Fig. 7) provided with a cutout for a wedge // on the board M for clamping it between the bars If (Fig. 1-3).
