Abstract

The invention relates to machine tool industry, in particular to gear processing. The inventive machine consists of a bed 1; tool rack 2, product rack 3. On the tool rack (headstock) there is a faceplate 4 on which the electric motor 5 is mounted via gears 6 connected to the crank 7, which is connected via rods 8 to the racks 9 (right and left), which interact with sector 475 wa # Л 10, the incisors 11 move. The last one is placed on circular (radius) guides with a dovetail section. Cutters 11 (right and left) are secured to sector 10 with screws. A worm wheel 14 is placed inside the tool head 2, which engages with the worm 15. From the worm, the movement is transmitted to the break-in guitar 16 and further, through the gears 17, the movement is transmitted to the rotation angle guitar 18 and further, through the bevel wheels 20 and 21 to the shaft 22 and to the headstock of the products, then to the dividing guitar 23 and through the gears 24 to the worm to 25 and the worm wheel 26.

Description

The invention relates to machine tool industry, in particular to gear processing.

The purpose of the invention is to expand technological capabilities by creating conditions for the simultaneous cutting of one of the convex and concave sides of the tooth with the other.

In FIG. 1 shows a general view of the machine; in FIG. 2 is a view A in FIG. 1; in FIG. 3 - a fragment of the drive - the connection of the rail with the sector; Fig. 4 is a schematic illustration of a gearing process; Fig. 5 is a fragment of the drive — the connection of the crank to the cutter; in FIG. 6 is a section BB in FIG. 3; in FIG. 7 shows planing of concave teeth.

The machine consists of a bed 1, tool stand 2, product stand 3. On the tool stand (headstock) is placed faceplate 4, on which the electric motor 5 is mounted via gears 6 connected to the crank 7, which is connected via rods 8 to the racks 9 (left and right ), which, interacting with sector 10, move the rubber 11, the latter is placed on circular (radial) guides 12 with a dovetail section. The cutters 11 (right and left) are fixed to the sector 10 by means of screws 13. Inside the tool head 2, a worm wheel 14 is placed, which engages with the worm 15. From the worm, movement is transmitted to the break-in guitar 16 and then through gears 17 the movement is transmitted to the guitar of the rotation angle 18 and further, through the bevel wheels 20 and 21 to the shaft 22 and to the headstock of the product, then to the guitar of the division 23 and through gears 24 to the worm to 25 and the worm wheel 26. The cutting edges 27 and 28 are made at an angle 20 °. The workpiece of the cut bevel gear 29 is rotated together with the cutters 11 about the axis X-X, making a rolling movement to form an involute on the tooth x of the cut workpiece.

teeth are used cutters 30 having a disk shape; the left cutter is fixed on the axis 31, and the right one on the axis 32 and with the help of rods and sector 10 have a precise movement around its axis,

The machine operates as follows.

The cutters 11 right and left make the main movement along the radial guides 12: reciprocating movement, strict tooth cavities on both sides, the movement is made using sectors 10 from the racks 9, connecting rods 8, the crankshaft 7 and the electric motor 5, the washer 5 rotates around along their axis X-X and together with the clasp 29 and the cutters 11 they perform a rolling movement to form an involute.

Claims (1)

The claims A dentition machine for cutting bevel wheels with a table placed on the bed and a tool stand with a cradle, on the circular guides of which, with the possibility of adjustment, there are two sectors with cutters mounted to move from the drive, including a crank with a rail, characterized in that, with the purpose of expanding technological capabilities by creating conditions for the simultaneous cutting of the convex and the concave sides of the tooth with one incisor and the other with the concave sides of the tooth, the machine is equipped with a second a crank with a rail and an electric motor with a reduction gear mounted on the cradle and connected to each of the crank, while on the cylindrical surface of the sectors there are gear rims designed to interact each with its own rail, and on its end surface - guides in the shape corresponding to cutters intended to be mounted on them. 5 W fl 29
