Description

The invention relates to machine tools. for the manufacture of nests in various materials, using milling tape as a tool, and is intended to enable the execution of several nests with one installation of the material being processed, making these nests inclined to the surface of the material in required cases. In order to implement the required installation of the working chain, the machine bed can be turned around the horizontal axis, and the chain itself can be turned in the same bed near the vertical axis and properly raised or lowered relative to the machine bed.

In FIG. 1 shows a side view of the machine bed; FIG. 2, too, rear view; FIG. 3-vid machine in front; FIG. on the side of a part of the mechanism of turning the working chain around the rotary axis; FIG. 5 is a front view of the mechanism for tensioning the working chain; fig; .6- the same. side view; FIG. 7 is the same, top view; FIG. 8, 9 is a side view of a part of the working circuit in two versions.

The proposed machine consists of a body (Fig. 1, 2) carrying an infinite milling machine used as a gun, a chain that can be installed with a slope of up to 45 ° to the vertical, in order to produce inclined cuts in the material placed on the table

(291).

machine tool. The machine body consists of a table / and a rotary frame D fixed on the axis 4 and provided with an arcuate guide / 5 and spikes / 5 in the lower part. In the upper part of the frame 3, a working milling chain is fixed (in Figs. 1 and 2, the chain is not shown). On axis 4, a jagged sector b is engaged, coupled with two gears, axis 5 of which is driven by gears 8 connected to each other by an endless chain.

In the lower part of the bed 3 ,,, on the ring //, connected with roller 72, the counterweight 16 is suspended, Roller 12, guided during its movement with the counterweight 16 by arc 15, is connected by cables with the ends of 19 axes 5 bearing gears 7, moreover, cables go around blocks 9.

When rotating the gears in one direction or another, the gear sector 6 together with the base 3 rotates to the corresponding angle, while simultaneously the counterweight 16 moves accordingly due to the connection of the roller 12 with the bsyO5 respectively. When rotating the base 5, the working milling this rotation is set at a certain angle to the material.

The base 3 in the upper part is provided with a cylindrical cup (Fig. 3), to which the bolts are attached to the bottom to the author's certificate of V.N. Minikh No. 33277

In the proposed clamp, a crossbar is used for the carpentry workbench, which is rotatably and longitudinally displaceable. a guide groove formed in the lower part of the board, a workbench, and associated with a clamping sponge.

In FIG. 1 is a perspective view of a clip; FIG. 2 is the same side view; FIG. 3 is a top view of a workbench board with a clip attached to it and the object to be processed; FIG. 4-side view of the workbench; FIG. 5 is a perspective view of the clamping of a workpiece, inclined to the workbench board; FIG. 6. A perspective view of a modified clip.

The proposed clamp (Figs. 1-4) consists of a stand 8, carrying a crossmember 3 to a rail 5 fitted with straps 5 and 7 with a clamping sponge 4 fixed in a hinge 5, Sponge 4, when rotated relative to hinge b, for clamping machined on the workbench of the object //, guided by a plank 7 entering the opening of the sponge 4, and secured in a certain position by means of a wedge 72 Cross bar 3 stand 8 is rounded on top and when the clamp is in operation . (292)

the control bars / and 2 connected to the board 73 workbenches.

To secure the workpiece / 7 on the workbench, one end is placed between the board, / J of the workbench and the gasket M (Fig. 3), and the proposed clamp is brought to the other end, respectively, by moving it in the guide bars /, 2 boards J3. After proper installation of the clamp in relation to the object, the sponge 4 (FIG. 2) is turned by turning about the hinge b to the object / 7 and secured with a wedge / 2-.t

If it is necessary to handle objects oblique with respect to the workbench / 5 (Fig. 5), the clamp is also installed obliquely by appropriately rotating it together with the cross bar 3 in the guide bars L 2 of the board / 5.

The clamp described can be modified, instead of the guide for the clamping jaw 4 of the bar 7 to whom the clamp 9 is used (Fig. 6) connected to the stand, and in the bar 5 to fix the jaw 4 a groove M is made. In this case 4, when clamping the object to be processed, is guided with the aid of hairpins fO and secured in a certain position with a wedge / 7.
