Description

In the proposed plowing device, the rotation of the table carrying the billet of the circular saw being manufactured is carried out by means of tongs, which are freely seated on the vertical axis,. connected by a gear with the axis of the table of the device and pivoted with forceps, gripping when the axis rotates, the disk fixedly fixed above it.

In FIG. 1 is a side elevational view of the device of FIG. 2 - view from above.

The proposed dividing device is mounted to a machine for the manufacture of circular saws on a sled 3, receiving a movement from the spindle 4, which is manually rotated. The axis 11, holding the table for the workpiece 14 of the manufactured saw, is equipped with a gear 12, which engages a double-width gear 10, located on the intermediate axis 9 of the tool and interlocks, in turn, with Pin 9, sitting on the axis 5. Axis 5 , in addition to gear 6, is equipped with a disk 8 rigidly fastened with it and a lower spongy - forceps 7, which is rotatably planted on it with its front part. The tongs 7 are located in a horizontal slot provided with a scale 16 and cut with the jaws a disk 8, with the upper

tongs are grooved. In the slot of the body there are two stops 17, 18, mounted on a scale of 16, respectively, the required angle of rotation of the table fixture. A billet 14 of a manufactured circular saw, fastened to the table of fixture by means of a washer 13, is established by moving the slide 3 under the machine slide 1, equipped with a working tool for notching the saw teeth or wiring them.

When bringing the machine into operation, the table of the device together with the workpiece 14 installed by the step size of the teeth of the saw being made is made by turning the disk 8 with tongs 7, which are moved along the notch between the stops 17 and 18 installed according to the required angle of rotation. The rotation of the table with the workpiece 14 did not interfere with the fins that formed on the last burr; the axis 11 is fitted onto the loosely seated on it under gear 12, P1aboy 15; movable in a vertical direction by a rod 19 that is pressed into it from below, controlled by a foot pedal. When pressed, the pedal sponge is moved upward by the rod 19 of the washer 15, acting on the tester, nude 12 and the fixture table, lifts the workpiece 14 over the matrix 2 of the machine ..

The subject matter of the invention.

The separating attachment to the machine for making circular saws, characterized by the use of tongs 7, whose sponge is swiveled onto the vertical part of the front part

an axis 5 carrying the disk 8 connected by a system of gear wheels with the axis 11 of the table supporting the saw-piece, and the upper sponge provided with grooves serves to clamp the disk 8 between the jaws in order to rotate to the desired angle fixed by the stops 17, 18 on gkkale 16.
