(54) MACHINE FOR CANVAS FLOW

The invention relates to a machine tool industry and can be used in machine-building enterprises for grooving grooves, for example, in bearing manufacturing when pulling fillets on roller bearing rings.

A known machine for grooving the Kanak, comprising a spindle and a caliper, the longitudinal slide of which is kinematically connected with the drive shaft 1.

The disadvantage of this machine is that it does not provide simultaneous cutting of two grooves, which limits its performance and that it has narrow technological capabilities, since it is not suitable for grooving grooves located in planes at given angles to the axis of the part of the part .

The purpose of the invention: - increase in productivity and expansion of technological capabilities due to the simultaneous grooving of two grooves located in planes at specified angles to the axis of rotation of the part.

The goal is achieved by the fact that the machine is equipped with an additional support

and each caliper is mounted on a corresponding plate that is rotatably mounted around the drive shaft and parallel to the spindle axis, and the drive shaft is interconnected with the calipers through a gear mounted on it with the possibility of axial movement.

FIG. 1 shows the proposed machine, top view; in fig. 2 shows section A-A in FIG. one.

10 The machine for grooving grooves has a frame 1 on which a disk 3 with a gear wheel 4 and a limb is attached with screws 2. On the drive shaft 6 parallel to the spindle 7 are mounted on rolling bearings 8 rotary plates 9 and 10, which

 mounted on the disk 3 by means of bolts 11 entering its l-shaped annular groove. In the rotary plates 9 and 10 there are mounted gears 12 and 13, which engage with the gear wheel 4. On the rotary plates 9 and 10 are fixed support bodies 14 and 15, in which the shafts 16 and 17 are mounted on rolling bearings 18. At the ends of the shafts 16 and 17, bevel gears 19 and 20 are firmly seated, which engage with the bevel gear 21. The gear 21 is seated on the drive shaft 6 with the possibility of axial movement and fixed with a latch 22. Inside the housings 14 and 15 on the shafts 16 and 17 rigidly fixed drums 23 with cams 24 (on the second caliper is not visible). The longitudinal slide 25 and 26 are mounted to move from the action of the cams 24 through the housings 14, and 15. The cross slide 27 and 28 are mounted with the possibility of sliding along the longitudinal slide 25 and 26 in the transverse direction. On the cross slide 27 and 28, the tool holders 29 and 30 are rigidly fastened. For counting the longitudinal movements of the tool holders 29 and 30, limbs 31 and 32 are used, which are mounted on the feed screws 33 and 34, and using screws 35 and 36 you can make adjustment movements of the tool bits holders 29 and 30 in the transverse direction. The workpiece 37 is mounted on the spindle 7. The machine works as follows. Install the caliper relative to the axis of the spindle 7 at a certain angle depending on the workpiece 37 on the limb 5. To do this, loosen the nuts of the bolts 11, remove the gear 21 from the gears 19 and 20 from engagement. Manually using rollers-gear 12 and 13, the respective plates 9 and 10 are turned around the drive shaft 6, each caliper is set at a certain angle along the limb 5. Then the plates 9 and 10 are fastened with bolts 11 and the gear wheel 19 is meshed with gears 19 and 20. With screws 35 and 36 made the regulation of the provisions of the incisor holding Avok 29 and 30 in the transverse direction, and with the help of the feed screws 33 and 34 on the limbs 31 and 32 adjust the tool holders 29 and 30 to the extreme positions of their longitudinal feed. Include a machine electric motor (not shown) which, through appropriate kinematic gears, drives the spindle 7 with the workpiece 37 installed on it and the drive shaft 6. The shaft 6 transmits rotation through bevel gears 19 and 20 by a drum 23 with cams 24, which convert the rotational movement into translational movement of the longitudinal slide 25 and 26 and the associated tool holders 29 and 30 (high speed, working stroke, fast retraction). The present invention makes it possible to simultaneously process two grooves located at arbitrary angles to the spindle axis, thereby increasing productivity and expanding the technical capabilities of the machine for grooving the grooves. Claims A groove groove machine comprising a spindle and a caliper, the longitudinal slide of which is kinematically associated with a drive shaft, characterized in that in order to increase productivity and expand technological capabilities by providing simultaneous groove of two grooves located in planes at given angles to the axis of rotation of the part, it is provided with an additional caliper and each caliper is mounted on a corresponding plate mounted to rotate around the drive shaft and spindle parallel to the axis, and the drive shaft is interconnected with calipers through a gear mounted on it with the possibility of axial movement.
