SU24641A1 - Adaptation to the planer for division - Google Patents

Description

The proposed adaptation to the planer for applying divisions consists of a base, in the groove of which a slider moves, carrying at one end of the axis rotating arms with cutters for applying divisions.

The levers under the weight of the load are supported by rollers mounted on one end of a reciprocating mobile pole under the action of an eccentric mounted on the end of the machine shaft, as a result of which the cutter blades alternately lower and raise, causing division.

In FIG. 1 is a side view of the device; FIG. 2 - its top view; FIG. 3-gear from the shaft of the machine to the workpiece m cylindrical shape.

In the base 1, mounted on the machine, the prism 2 moves on the prismatic guides, on the stand of which the levers 3 with weights sit on the axis 4. The levers 3 on the other end carry holders with cutters 4. On the stand of the slider 2, in its upper part, there is a knurled screw that serves to lift the tool when installing the workpiece. In the slider 2 and in the bearing 7, a shtanga 8 is placed, which receives movement from an eccentric 9 fixed on the end of the machine shaft, and has

reverse stroke under the action of a spring located in the support 7 and adjustable by a pressure screw.

Rod 8 carries racks 10 and 11, of which the first has a roller at the end that is in contact with the eccentric 9, and the second is a stop bolt 12 with a lock nut. On the rack 11 there is also a dog 13 with a spring and adjusting screws, which are located on both sides and respectively install it. On the base 1, the stand 14 is reinforced, bearing on the rod a copying disc with a ratchet 15, the number of teeth of which corresponds to the number of scratches of different lengths applied on the workpiece. A copying disc on a circle has one or more notches corresponding to longer risks. The locking bolt 12 constantly touches the rotatable copying disc, and as the rod 8 goes into its recess, the rod 8 moves further, which gives the touch point of the roller 17 seated at the end of the rod 8 with the levers 3 and, therefore, increases the span of the arms. The slider 2 has a pin 16. The shtanga 8, which enters the oblong slot, is always ahead of the slider 2 carrying levers with chisels, and therefore

“Reverse idling roller 17 lifts the levers 3, and with them the incisors ..

On the rack 14, another dog is hardened, keeping the ratchet 15 from turning. The product is fastened with special clips on a cross support mounted on a glass table. Suport is reported to move from the spindle, on the end of which the ratchet 19 is mounted, which is rotated by means of a rod 20, articulated with an eccentric 9. When the eccentric 9 rotates, the slider with the lever 3 "receiving alternating movements causes division on the product. During the return stroke of the slider, the shtanga raises the levers 3: 4 incisors, the last passes over 5 points, etc.

To apply tick marks on round products, for example, micrometer vernies, a transfer consisting of a ratchet 19 mounted on a smooth shaft 21 communicating by means of a worm gear can be used to coordinate the movement of the rod with the turns of the products being processed. rotation of the shaft 22 with the gear 23, coupled with the same teeth sitting on the mandrels for the products to be processed.

The subject matter of the invention.

A trimming attachment equipped with a copying disk for adjusting the length of the scratch marks, characterized by the use of a rod 8 that is movable on a slider 2 and equipped with a roller 17 to act on the bearing cutter 4 to lift it at idle.
