Automatic centering seal cover press-fitting machine for double row conical bearings

Abstract

The present invention discloses an automatic centering seal cover press-fitting machine for double row conical bearings, and belongs to the technical field of bearing manufacturing. The automatic centering seal cover press-fitting machine comprises two hydraulic cylinders that are disposed on bedplates oppositely and fixedly, and two centering cover pressing devices disposed oppositely and connected to the two hydraulic cylinders, respectively. A bedplate height adjusting device is arranged below each centering cover pressing device. The automatic centering seal cover press-fitting machine for double row conical bearings has the following advantages: first centering and later press-fitting are achieved by means of the centering cover pressing devices to take the place of existing manual placement of seal covers onto bearings, and therefore, rejected products after press-fitting due to placement position errors can be avoided; according to the press-fitting machine, horizontal simultaneous two-side press-fitting is implemented without manual reversing of bearings, such that the workload is reduced, and the working efficiency and quality are improved; moreover, the bedplate height adjusting devices are provided for adjustment to enable the centers of different bearings to coincide with the centers of the hydraulic cylinders, and the production of bearings different in specification is thus realized.

Description

technical field [0001] The invention relates to a centering and pressing cover device for a bearing, which belongs to the technical field of bearing processing. Background technique [0002] The sealing cover of the existing double-row tapered bearing is pressed by hand, and the sealing cover is placed on the upper end of the bearing or placed in the cover head tooling. When it is placed on the upper end of the bearing, the center of the sealing cover and the center of the bearing It is difficult to overlap. This method will cause eccentricity during the pressing process, and the sealing cover will not be pressed in a state completely perpendicular to the bearing, so there will be burrs, which will cause the sealing cover to be unqualified after being pressed; When the cover head tooling is inside, it can ensure that the cover head tooling and the sealing cover are completely concentric, but it cannot guarantee that the cover head and the bearing are completely concentric, a...

[0002] The sealing cover of the existing double-row tapered bearing is pressed by hand, and the sealing cover is placed on the upper end of the bearing or placed in the cover head tooling. When it is placed on the upper end of the bearing, the center of the sealing cover and the center of the bearing It is difficult to overlap. This method will cause eccentricity during the pressing process, and the sealing cover will not be pressed in a state completely perpendicular to the bearing, so there will be burrs, which will cause the sealing cover to be unqualified after being pressed; When the pressure cover head tooling is inside, it can ensure that the pressure cover head tooling and the sealing cover are completely concentric, but it cannot guarantee that the pressure cover head and the bearing are completely concentric, and eccentricity will also occur
