Upper-pressing oil seal device for end cover

Abstract

The invention aims at providing an upper-pressing oil seal device for an end cover and capable of greatly improving a pressing-fitting effect for oil seal and the end cover. The upper-pressing oil seal device for the end cover comprises a bottom plate, wherein an oil seal loading mechanism, an end cover placement seat and a pressing machine are arranged on the bottom plate; the oil seal loading mechanism comprises an upper fixed plate; the upper fixed plate is provided with a charge hole penetrating through from top to bottom and allowing the oil seal to pass through; a lifting drive device isarranged at the lower side of the upper fixed plate; a lifting plate is arranged at an output end of the lifting drive device; the lifting plate is provided with an oil seal placement groove used foraccommodating the oil seal; the pressing machine is located at the front side of the upper fixed plate; a pressing head of the pressing machine at least comprises a first section of the pressing headand a second section of the pressing head; the first section of the pressing head is located at the lower side of the second section of the pressing head and provided with a step structure; the pressing head moves downwards to press the oil seal on the first section of the pressing head into an oil seal fixing groove of the end cover through the second section of the pressing head; the end coverplacement seat is arranged at the lower side of the pressing head of the pressing machine; and the lifting drive device is linked with a first linear drive device.

Description

technical field [0001] The invention relates to a pressure oil sealing device for an end cover. Background technique [0002] The press-fitting of the oil seal is different from the press-fitting of the bearing. When the bearing is press-fitted, the bearing can be placed on the upper end of the end cover bearing block to realize the pre-positioning of the end cover and the bearing. Since the oil seal is small in size and easy to deform, it cannot The oil seal is placed on the upper side of the oil seal fixing groove of the end cover to pre-position the two before press-fitting, which will cause a gap between the outer wall of the oil seal and the inner wall of the oil seal fixing groove of the end cover, and the oil seal and the oil seal fixing groove of the end cover are not in the same axis. The use effect becomes worse. Contents of the invention [0003] The purpose of the present invention is to provide an end cap pressing oil seal device with greatly improved effect ...
