The invention relates to mechanical engineering and can be used in the mass production of gear products.

UeJib invention - increase the rigidity of the head and improve the performance of dental processing.

FIG. 1 shows the design of the head; in fig. 2 is a view A of FIG. one; in fig. 3 - head cutter; FIG. A is a section BB of FIG. 3

The head comprises a housing 1, in the radial grooves 2 of which the incisors 3 are located, consisting of tail and cantilevered parts. The housing 1 is provided with radial holes A, in which the clamps 5, the spring 6 and the threaded plug 7 are located. The housing 1 with the bolts 8 and the nuts 9 is installed on the (1 shaft 10 equipped with an annular groove II in which the heads of the bolts 8 are located. In the central hole of the housing 1 on the centering 12, a taper 13 of the pit is mounted around its axis, secured with a bolt 1A, on which a coolant supply device 16 is installed in the cutting zone with the help of a bolt 15 On the taper 13 of the feed .Cutting tool 3 This unit interacts with the feed cones 13 and the feed 17. In addition, the cutter 3 is provided with a support surface 18 and two-sided two-sided ledges 19 and 20 on the console part of the cutter, on which the ring 21 rests. The thickness of the ring 2 is equal to the size B cutter 3.

The ring 21 is fixed on the body i and is provided with radial samples: and 22, covering the cantilever part of the cutter 3. Each cutter 3 is a group of re) 5 core elements (rough and finishing), where a known 2: 1 ratio of rough and finishing pu: all elements arranged in alternating order with a step equal to the circumferential pitch of the teeth of the machined toothed contour.

The ratio of 2: 1 roughing and finishing cutting elements is maintained for the head as a whole.

The device works as follows.

Before installing the cutters 3 in the radial grooves 2 of the housing 1, remove the bolt 15 and the coolant supply device 16. Loose bolt 1A and nuts 9

so that the feed cone 13 and the frame 1 of the pocket rotate around its axis relative to the centering 12 and the flange 10 with the annular groove II. In this case, the claws 5 are removed from the radial grooves 2 and rotated 90 ° relative to the CBoeii axis so that their heads rest on the outer cylindrical surface of the housing 1. Then the cutters 3 alternately, in order of marking in the coupling, are installed in the radial grooves 2, and the clamp 5 is inserted also in the radial} 1st slot 2 and its golopka comes into contact with the support surface 18 of the cutter 3, ensuring 1p standing pressure of the tail part of the cutter 3 against the conical surface of the feed cone 13. When installing the cutters 3 in the radial grooves 2 of the housing 1, they gradually turn on the bolts 8 located in the annular groove 11 of the flange 10. The pressing force of the cutters 3 to the feed cone 13 and the amount of the sticking force 5 are adjusted by the threaded plug 7.

After installing the KOMiuieKTa cutters 3, body 1 is bolted on the flange 10 with bolts B and t-aek 9 and the feed cone 13 is bolted on the junction box 12 with bolt 1A. Then the coolant sprinkler 16 is attached to the feed cone 13 with the bolt 15 13 feed, mixed along the cBoeii axis, performs a radial feed cut up to .4 3 for plunging into each double stroke of the workpiece, which performs a reciprocating motion and at the same time} periodic circular pressure. The removal cone 17 removes the incisors 3 from the profile to be processed during the reverse (idle) course of the workpiece due to the interaction of its inner conical surface with the tail part of the incisor 3.

During the cutting process, under the action of the cutting force, the cutters 3, with their lateral benches 19 and 20, rest on the lower surface of the ring 21, which at the expense of radial samples 22 encompasses the cantilever part of the cutters 3, while increasing the bearing surface of the cutters 3 significantly reduces the bias their tail part in the radial grooves 2. The cutting force ensures the self-fastening of the incisors 3 and additional pressing of the ring 21 to the body 1 by means of lateral ledges 19 and 20 that are raised to its lower surface, which increases the reliability of fastening lp.a 2

the joint with the housing 1, since the fastening bolts (not shown) of the ring 21 in this case are relieved by tensile force.
