Definitions

  • the invention relates to a device for mechanical finishing of running surfaces of rolling bearing rings, in particular for the machining of running surfaces on cylindrical roller and tapered roller bearings. Finishing is an additional processing step to improve the roughness and dimensional accuracy of machined surfaces. Finishing usually involves a chip removal of a few micrometers. During finishing, the workpiece to be machined is driven in rotation. The processing takes place by means of a finishing stone, which performs oscillating movements during processing. The oscillation path and the oscillation frequency have an effect on the final result.
  • a device for finish machining of rolling bearing rings is made EP 0 936 028 B1 known.
  • the known device comprises two linearly adjustable in the X-, Y-direction carriages and arranged on one of the carriage pivoting device with a stone holder for a finishing stone.
  • the positioning movements in X-, Y-direction and the pivoting movements of the stone holder are controllable depending on the workpiece profile to be machined.
  • the finishing stone is movable over the workpiece surface to be machined and follows the contour of the workpiece surface.
  • the running surfaces can be edited on bearing rings of spherical roller bearings, cylindrical roller bearings and tapered roller bearings.
  • the invention has for its object to provide a device for universal finish machining of bearing rings for cylindrical roller and tapered roller bearings, which is structurally simple and is characterized in that the to be moved for an oscillatory movement of a finishing stone masses are small.
  • the Oszillationsweg and the oscillation frequency with which the finishing stone is moved over the workpiece surface to be machined, should be variable fixable.
  • the invention relates to a device according to claim 1 for the mechanical finishing of running surfaces of rolling bearing rings.
  • the object is achieved in that the eccentric drive has an NC-controlled servo drive, the output shaft reversing movements with freely programmable pivot angle executes that the carriage guide is disposed on a rotary plate which is rotatably mounted about a coaxial to the output shaft axis on the support, and that the tool carrier has an adjusting device for linear adjustment of the stone holder transversely to the direction of movement of the carriage.
  • the workpiece to be machined is clamped to a workpiece spindle and set in rotation during finishing.
  • the spindle axis of the tool spindle and the direction of movement of the carriage of the device according to the invention are aligned in parallel.
  • the eccentric drive for generating oscillatory movements of the carriage has a highly dynamic servo drive, which performs reversing rotational movements.
  • the swivel angle of the servo drive is freely programmable. Since the output shaft of the servomotor acts by an eccentric on the slide, changes with the tilt angle of their reversing movements at the same time the linear stroke of the carriage. The linear stroke of the carriage and the pivot angle of the output shaft are in a fixed relationship to each other. By the motor speed of the servo drive, the oscillation frequency of the linear stroke is also variable. Both the swing angle for the reversing motions of the output shaft and the motor speed of the servo drive can be continuously changed during a finish machining to affect the finishing. By an appropriate control of the servo motor oscillatory movements with short stroke or long stroke and also with different frequencies can be generated. Furthermore, long stroke oscillatory motions and short stroke oscillatory motions may be superimposed.
  • a connecting piece is connected to the output shaft of the servo drive, which has a staggered to the shaft axis of the output shaft arranged pin.
  • the pin cooperates with sliding surfaces on the carriage, which transmit a component of the pin movement acting in the direction of movement of the carriage onto the carriage and permit a pin movement transverse to the direction of movement of the carriage.
  • two stop elements are preferably attached to the carriage, which are arranged on both sides of the pin with a height offset opposite and having a planar gate surface, which rests against each one arranged on the pin bearings.
  • the device according to the invention has a modular structure and can be retrofitted in a few steps so that the device can be used by using the servo drive for finish machining of roller bearing rings for ball bearings.
  • the rotary plate, the carriage assembly and the connector for transmitting the oscillatory movements of the output shaft form a replaceable module.
  • the tool carrier is directly or indirectly connected by means of an adapter to the output shaft of the servo drive.
  • the reversing movements of the motor are transmitted as pivotal movements on the stone holder, so that the device can also be used for finishing of spherically curved surfaces.
  • Users who use the device according to the invention first for machining roller bearing rings for ball bearings want to use the device can subsequently by installing the assembly described also for processing Zylinderrollenlagem and tapered roller bearings use.
  • the entire device can be connected to an adjusting device, for. B. to a carriage, are connected, with which the device between a working position and a second position in which the finishing stone is spaced from the workpiece surface, is movable. If the device takes the second position, a trouble-free workpiece change is possible.
  • the carrier is therefore fastened by means of a clamping device to push rods, which are displaceable with a predetermined travel between two positions.
  • the device 1 shown in the figures is used for mechanical finishing of raceways on rolling bearing rings for cylindrical roller bearings and tapered roller bearings.
  • the device 1 is associated with a tool spindle 2 in which a workpiece 3 to be machined is tensioned and can be driven in rotation about the spindle axis 4 during finish machining.
  • the basic structure of the device 1 includes a carrier 5, a carriage assembly 6, which has a carriage 7 and a slide guide 8 for linear guidance of the carriage 7, an eccentric 9 for generating oscillatory movements of the carriage 7, a tool carrier 10 fastened to the carriage 7 and a tool holder 10 connected to the stone holder 11 with a finishing stone 12.
  • the tool carrier 10 has an adjusting device 13 for linear adjustment of the stone holder 11 transversely to the direction of movement of the carriage 7. During finish machining, the finishing stone 12 bears against the peripheral surface of the rotationally driven workpiece 3 with a predetermined pressure force.

  • the eccentric 9 an NC-controlled servo drive 14, z. an AC servomotor, on.
  • the output shaft 15 of the servo drive 14 performs reversing rotational movements, wherein the pivot angle ⁇ is freely programmable.
  • the reversing rotational movement is transmitted to the carriage 7 by an eccentric arrangement 16.
  • the pivot angle ⁇ By adjusting the pivot angle ⁇ , the stroke of the carriage 7 is variable.
  • the oscillation frequency of the oscillating movement performed by the finishing stone 12 is also controllable.
  • the carriage guide 8 is arranged on a rotary plate 17, which is fastened to the output shaft 15 coaxial axis 18 rotatable on the carrier 5.
  • the axis of rotation 4 of the workpiece and slide guide 8 are aligned parallel to each other ( Fig. 6a ).
  • the rotary plate 17 is adjusted by an angle ⁇ , so that the carriage guide 8 is aligned parallel to the cone / conical surface to be machined ( Fig. 6b ).
  • a connecting piece 19 is connected, which has a shaft 20 of the output shaft 15 offset staggered pin 20 has.
  • the pin 20 cooperates with slide surfaces 21 on the carriage 7, which transmit a acting in the direction of movement of the carriage 7 component of the pin movement on the carriage 7 and allow a pin movement transverse to the direction of movement of the carriage 7.
