Problems solved by technology

Grinding wheels wear very quickly, and in some cases, research into reducing cycle times has resulted in increased part movement speeds, which can lead to too sudden contact between the part to be machined and the machined wheel, resulting in premature wear, Even the damage of the grinding wheel

Embodiment Construction

[0031] [31] Reference Figure 1A and 1B , the shown grinding machine 10 includes: a frame 11, which includes a lower part 11a and an upper part 11b; an electrical cabinet 12; , and is connected to an automatic feeding device 14 of the bearing ring to be ground; Figures 3A to 3C An automatic unloading device 15 of the ground ferrule is shown; and a console 16, which is fixed on a movable arm 16a and has a display screen and a keyboard. Preferably, the upper part 11b of the frame 11 is glassed and allows access to the grinding unit 13 . The electrical cabinet 12 includes all electrical components for powering and operating the machine. The space defined by the lower part 11a of the frame contains the hydraulic components and lubricating devices required during the machining of the part. Depending on whether the ring to be ground is the inner ring or the outer ring of the bearing, the grinding unit 13 differs from one machine to another. Since the design of the present inven...

Abstract

A bearing ring grinding machine comprising a grinding unit arranged to provide machining quality with micron-size tolerances and a reduced grinding cycle period. To this end, the grinding unit (13) comprises a fixed plate (13a) on which are mounted a loader (14c) and a sliding carriage (20) arranged to move horizontally in the direction of the double arrow A. A sliding carriage (20) stopper (21),in the loader (14c), holds the inferior ring (100) applied against the plate (13a) and maintained between two lateral channels. The fixed plate (13a) has a passage opening for a rotatable spindle (22)equipped with a magnetizable socket (23) to support a ring during machining and two adjustable support stops (24, 25) for automatically positioning the rotating ring on the socket (23). At first, thesliding carriage (20) releases the passage for a ring (100) to be grinded toward the magnetizable socket (23) of the rotatable spindle (22), through a magnetic carrier tape (14b) in order to, at a second moment, maintain the ring (100) against the two stops (24, 25) during their machining and in order to, at a third moment, transfer the grinded ring (100) from the support position toward an automatic discharge device (15).

Description

technical field [0001] [01] The present invention relates to a machine tool for grinding bearing rings, comprising a machine frame, an automatic feeding device, a grinding unit, an automatic unloading device for grinding bearing rings, an electrical cabinet and a control unit The grinding unit comprises: a rotating spindle equipped with a magnetizable sleeve for supporting the ferrule during machining, and two adjustable support stops for automatically positioning the rotating ferrule on the sleeve on the barrel. Background technique [0002] [02] Bearing ring grinding machines, either ball bearings or roller bearings, must work in a fully automatic manner and are therefore usually dedicated to this function. Their equipment conforms to the dimensions of the relevant bearings and the individual specifications of the bearings correspond to certain equipment. The decisive parameters required for bearing ring grinding are cycle time, machining accuracy and the duration of the...
