This invention relates to mechanical engineering, in particular, to machine tools.

The purpose of the invention is to improve the quality of machined parts by matching the rotational and reciprocating speeds, the spindles.

The drawing shows a hydrokinematic scheme of the honing machine.

The honing machine contains a housing 1 on which the drives 2 and 3 of the reciprocating mechanisms are mounted, made for example in the form of hydraulic cylinders, the rods of which are made in the form of screws 4 and 5 connected with nuts and gears. mi 6 and 7. Screws 4 and 5 are rigidly connected to the spindle head 8, the floor, it has a drive shaft 9. In the spindle head the drive for unclamping honing sticks is mounted, made, for example, in the form of a hydraulic cylinder 10, the rod of which is connected to the drive shaft 9. Nuts sheepsterni 6 and 7 are kinematically connected with gears 11 and 12 drive vraseni spindle. The rotational drive elements are coupled to the drive shaft 9 and the spindle 13 by means of overrunning clutches 14 and 15 of versatile operation. Hoi (lapping) 16 is mounted on the spindle.

The machine works as follows.

When pressure is applied to the lower cavities of the cylinders 2 and 3, their rods move upwards. At the same time, screws 4 and 5 move upwards, headstock 8 with a drive shaft 9 and spindle 13 with a hone 16. At the same time, the nuts and gears 6 and 7 and associated with them gears 11 and 12 of rotation of the spindle rotate simultaneously and depending on the direction of rotation of the nuts one of the overrunning clutches 14 or 15, for example 14, is wedged, transferring the rotation to spindle 13 with hon 16,

for example, clockwise. After reversing the hydraulic drive in the upper position of the turn, the direction of rotation of the g-wheel gears 6 and 7 and the gears 11 and 12 of the rotational drive change. In doing so, the working clutch 14 is wedged and the clutch 15 is wedged, transmitting rotation to the spindle with a hone in the same direction. The drive for unclamping the bars, made, for example, in the form of a hydraulic cylinder 10, allows the hone size to be adjusted in the course of work.

If it is necessary to change the angle of inclination of the grid, the gear ratios of the rotary drive are changed, for example gear ratios of 6-10 and 7-12 gears.
