Abstract

The invention is related to the field of mechanical engineering and can be used in the industry for superfinishing of the treadmills of the inner rings of mass bearing types. The purpose of the invention is to increase labor productivity, processing quality and simplify commissioning during superfinishing. To do this, on the rotor 3, in each of its working positions, there is a superfinishing unit, comprising a housing 4, in the vertical plane of which two coaxial holes for the spindle of product 5 and an auto-operator 6 are made, and in the horizontal plane two bores parallel to each other, equidistant from the axes of the vertical holes and perpendicular to it, under the tool heads 7 and 8, and the drive of the tool heads is fulfilled in the form of a face cam 30 mounted coaxially with the rotor shaft, m spindle product 5 through a three-stage pulley, V-belts and an electric motor with pulleys 22, and on the other hand through the system of levers, bearing, spring - with tool heads 7 and 8. beat.

Description

59, the gearbox 60 and the V-belt cycle cycle, curve 42 switches

redacci 61.

The device works as follows.

When the rotor 3 rotates counterclockwise at a speed v, the rings to be processed, from the loading tray 53, through the lead-in cone 55, enter the groove 54 of the receiver 26, where with further rotor rotation of the centrifugal, only the finishing abrasive bar 15 is processed. rotor 3 curve 43 switches

curve 56 relative to the spin — 40 valve 46, compressed air enters

of product 5 and auto operator 6. Curve 41, switching the spool 44, directs the compressed air through pipe 51, through distributing the cylinder of the finishing tool head 8 to discharge the finishing abrasive bar 15. Curve 4) controlling the operation of auto operator 6, hinge box 47 and the channel 52 in the lower 45 switches the valve 44, directed the new cylinder cavity of the auto-operator 6, the compressed air into the upper cavity of the box. as a result, when hydpus 23 is moved to lower the rod with a hydrostatic mandrel 25, located on the cylinder rod, with an auto-statstatic mandrel 25 and the ring to be processed. The lower end of the machined ring rests on the pawl 27, and the mandrel moves to the lowest position to load the next ring, while the machined ring remains on the upper 6, the upper ring 50 is placed on the mandrel 25 and, with further movement, spinning the pawl 27, is pressed against the end of the ring 21 mounted on the shaft of the spindle 5, rotating with speed v. The centering of the plane of the pawl 27, the rings on the mandrel 25 in front with a flush with the plane of the strips 28, is also superfinished by the further rotation of the rotor 3 by the oil going under pressure on the machined ring , through the distributor - the movable inclined bar 58 and the piercer 45, and the compressed air enters the. the case 16 of the rough tool head 7 on the waste of the rough abrasive bar 14 from the surface of the ring.

Further processing is carried out only with a finishing abrasive bar 15. Before completing one revolution of the rotor 3, curve 43 switches

valve 46, compressed air enters

into the cylinder of the finishing tool head 8 to retract the finishing abrasive bar 15. Curve 4), controlling the operation of the auto-operator 6, switches the spool 44, directed compressed air into the upper cavity of the housing 23 to lower the rod

static mandrel 25 and the processed ring. The lower end of the machined ring rests on the pawl 27, and the mandrel moves to the lowest position to load the next ring, while the machined ring remains on top of the plane of the pawl 27, which is flush with the plane of the rails 28, and with further rotation of the rotor 3 the machined ring, resting against the fixed inclined bar 58 and moving along this bar, falls into the loading tray 57. Later, the work of this position is repeated, and the work of the remaining positions proceeds similarly and in that order What they are located on the rotor.
