A machining center spindle motor connecting plate

Abstract

The invention discloses a connecting plate for a spindle motor of a machining center, which includes a connecting plate main body, a sealing cover is arranged on the top of the connecting plate main body, and the sealing cover and the connecting plate main body are threadedly connected by a plurality of inner hexagonal bolts. There is an oil groove inside the main body of the connecting plate, and the oil groove is distributed in a U shape inside the main body of the connecting plate, and the two ends of the oil groove are respectively provided with an oil inlet and an oil outlet, and an axial sealing ring and an oil outlet are arranged inside the main body of the connecting plate. A radial sealing ring, the axial sealing ring is arranged at the joint between the sealing cover and the main body of the connecting plate, and the radial sealing ring is arranged in the oil groove. The invention can inject cooling oil into the motor connection plate through the oil tank, oil inlet and oil outlet, and form a closed-loop cooling system inside the main body of the connection plate through external cooling oil, so as to control the surface temperature of the main body of the connection plate , The purpose of improving the processing accuracy of the equipment.

Description

technical field [0001] The invention belongs to the field of machining center spindle equipment, and relates to a motor connecting plate technology, in particular to a machining center spindle motor connecting plate. Background technique [0002] At present, the spindle transmission of machining centers is mainly divided into synchronous belt spindle, gear drive spindle, direct-coupled spindle and electric spindle. The direct-coupled spindle is mainly connected through the coupling between the spindle and the motor shaft, and is connected by the motor The plate fixes the motor on the spindle box. The precision and thermal conductivity of the motor connecting plate directly affect the precision of the spindle. It is also easy to deform when heated. Therefore, it is necessary to invent a motor connection plate with stable precision, better thermal conductivity or a function of forced cooling. [0003] The utility model patent with the notification number CN206788747U disclose...
