SU32162A1 - Dividing machine for the simultaneous application of scratches on cylindrical and conical products - Google Patents

Description

Dividing machines using several transverse calipers that carry cutters to apply marks on products are generally known.

In the proposed machine, there are two calipers, one for applying it with a cutter on the cylindrical product, and the other simultaneously on the conical one. Both calipers receive working movement from the common camshaft via separate gears for each caliper. The cone with a tapered piece can be rotated at known times with a gear coupling and cams mounted on the same camshaft. To lengthen the scratches, a lever is applied every five divisions, which, when applying these divisions, is applied to the spring cutter under the action of an eccentric mechanism.

In FIG. 1 shows the front view of the proposed machine; FIG. 2 is a side view of it; FIG. 3 is a top view.

The machine receives movement from the pulley 2 sitting on the shaft /, from which rotation is transmitted by means of a worm gear pair 3 to a roller 24 with a bevel gear 16 at one end and with a movable half of the gear coupling 6 at the other. The second half of the sleeve b sits on the spindle 23, in which the conical product being machined is attached. The cam 22, which is further located on the shaft 7, by acting through the lever on the movable part of the clutch 6 engages it at known times with the spindle 23 and causes it to turn the product around its axis. The curved knee of the shaft 7 serves as a crank 7 for communicating, via the rod 25, and the angular lever 28, to a reciprocating movement of the mounted obliquely support 5 with a chisel, causing risks on the conical product. A conical gear coupling 26 at the end of the shaft 7, its rotation is transmitted to the shaft 77, causing the second support 10 in reciprocating motion through the eccentric P to support the spring-loaded cutter for applying the marks on the cylindrical article 27 fixed on the machine table. The movement of the support plate 10, which is progressive along the product, is carried out by the lead screw 8, which is rotated from the roller 24 by means of bevel gears 15 and 16.

For putting on cylindrical article 27 on the fifth, tenth, and t, d. Divisions of longer lengths, a worm gear 11-12 is arranged from shaft 77 to shaft 13, on which an eccentric sits, acting thanks to its outline “14 pressing the cutter, so that the last every four divisions puts on the fifth a longer risk.

with taper during

the application of risks by the chisel in the car is adapted to the brake 18, and for the same - caliper restraints - the brake 19.

The subject matter of the invention.

Claims (3)

1. A separating machine for simultaneously applying scratches to a cylindrical and conical product with the help of incisors fixed on separate calipers, characterized in that in order to communicate the working movement of the incisors, the camshaft / applied to the caliper 5 through the crank 7 and the angular lever 25 , with periodic turns of the product, and on the caliper 10-using the shaft 77 and the eccentric 9. 2. In the machine of claim 1, apply on the camshaft / cam 22 for acting by means of the lever 4 on the toothed coupling 6 for the purpose of communicating the spindle 23 with the workpiece at the appropriate moments of rotation. 3. In a machine according to claim 1, use for lengthening the scratches on every fifth, tenth, and so on dividing lever 14, which serves to press the spring cutter under the influence of an eccentric on the shaft 13 connected by a worm gear with vgiuom 77.
