摘要:
This grinding machine (2) for bearing rings (500) includes a frame, a rotating grinding wheel (6) movable in rotation around a first rotation axis (X6), a working station where a bearing ring stands during a grinding operation of one of its surfaces, a chuck (244) for holding a bearing ring in the working station, this chuck being movable in rotation around a second rotation axis (X24). This machine includes first automatic means to set the position of a shaping tool (12) with respect to an outer peripheral edge (10) of the grinding wheel (6), these first automatic means including an electric motor (702), an encoder (710) coupled to the electric motor to detect a rotation of an output shaft (704) of this motor, a sensor (708) of the position of the shaping tool along a translation axis (Y12) and means (800) to compare an output signal (S 710 ) of the encoder and an output signal (S 708 ) of the sensor. The machine also includes second automatic means to set the axial position of the chuck (244) along the second rotation axis (X24), these second automatic means including an electric motor (902) for driving the chuck in translation (A24) along the second rotation axis and means (910) to detect a rotation of the chuck around the second rotation axis.

This grinding machine (2) for bearing rings includes a frame, a rotating grinding wheel (6) movable in rotation around a first rotation axis and a nozzle (150) adapted to inject (A2) a liquid coolant on a peripheral portion (10) of the grinding wheel. The nozzle (150) is mounted on a first slide (152) movable in translation along a second axis (Y154) perpendicular to the first rotation axis (X6) and the position of the slide along the second axis is controlled by a mechanical linkage (152, 172, 190, 202, 204) connected to a movable part (170) of the machine whose position depends on the outer diameter of the grinding wheel (6).

This honing machine (2) for bearing rings (102) includes a frame (12), a honing tool, a honing station (14) for holding a bearing ring in position with respect to the honing tool, the honing station including a workpiece holder (18) with a concave surface (182) equipped with at least one pad for supporting a bearing ring. The workpiece holder (18) is equipped with a damper (190) movable between a first active configuration, where it protrudes on a path of a bearing ring (102) moving towards the workpiece holder (18) in the honing station (14), and a second passive configuration, where it is out of reach of a bearing ring in the honing station.

This grinding (2) machine for bearing rings (500) includes a frame (4), a rotating grinding wheel (6) movable in rotation around a first rotation axis (X6), a working station (14) where a bearing ring (500) stands during a grinding operation (R6) of one of its surfaces. This grinding machine also includes holding means for holding a bearing ring in the working station and transfer means (100, 200) for transferring bearing rings (500) to and from the working station (14). The transfer means include at least a multi-axis robot (100) and a ring moving arm (200) provided with gripping means for temporarily gripping a bearing ring, this ring moving arm being rotatable around a second rotation axis (X200), parallel to the first rotation axis (X6), and movable in translation along this second rotation axis.

This honing (2) machine for bearing rings (100, 102) includes a frame (12), a honing tool, a honing station (14) for holding a bearing ring (100) in position with respect to the honing tool and a transfer mechanism (20) for feeding the honing station with bearing rings, one after the other. The transfer mechanism includes a first transfer box (202), adapted to accommodate a bearing ring (102) and movable in translation, in a to-and-fro movement with respect to the frame (12), along a first axis (Y202), and a second transfer box (204), adapted to accommodate a bearing ring and movable in translation, in a to-and-fro movement with respect to the frame, along a second axis (Y204) parallel to the first axis. The transfer mechanism (20) also includes first and second driving means for driving the first and second transfer boxes in translation along the first and second axes (Y202, Y204). The second transfer box (204) is located under and adjacent the first transfer box (202), above the honing station (14). The second transfer box (204) has a top inlet opening (204A) which is vertically aligned with a bottom outlet opening (202B) of the first transfer box (202).
摘要:
This workpieces processing machine comprises a handling tool (106) for loading a working station of the machine with workpieces (500) to be processed. This machine includes a laser detection cell (650) and computation means configured to compute at least a first dimension (D 500A , D 500B , D 500C , L 500 ) of a workpiece (500) on the basis of a position of the handling tool when the workpiece crosses a laser beam (B 650 ) of the laser detection cell (650) while being moved by the handling tool in a first direction (D1). The method is for automatically controlling some dimensions (D 500A , D 500B , D 500C , L 500 ) of workpieces (500) to be processed in a working station (14) of a machine (2). It includes at least steps consisting in a) picking a workpiece (500) in an inlet station (300) of the machine, b) moving the workpiece with a handling tool (106), in a first direction (D1) towards a laser beam (B 650 ) of a fixed laser detection cell (650), c) detecting the position of the handling tool (106) when the workpiece crosses the laser beam (B 650 ) along the first direction (D1) and d) computing a dimension (D 500A , D 500B , D 500C , L 500 ) of the workpiece on the basis of the position of the handling tool (106) detected at step c).
