AI Technical Summary

Technical Problem

Before assembling the motorcycle engine spindle box cover, the bearing and oil seal need to be installed in the corresponding position of the spindle box cover in advance. However, due to the complex shape of the spindle cover and difficult to position, it is difficult for the prior art to press multiple bearings into the same time. The operation is complicated and easy to press and crook, which seriously affects production efficiency.

Method used

A high-efficiency spindle cover bearing pressing fixture is provided, including an upper pressing holding mechanism, a middle fixing mechanism and a lower support pressing mechanism. The upper pressing and holding mechanism overcomes the elastic force of the first elastic element by the first pressing and holding part, so that the first pressing and holding part gradually moves into the first through-hole along the first connecting part, so as to achieve soft pressing and holding on the area where the bearing is mounted on the outside of the spindle cover. The middle fixing mechanism and the lower support and pressing mechanism overcome the elastic force of the elastic element through components such as adjustable limiting rods, reference pins and pressure bearings, and gradually press the bearing into the spindle cover.

Benefits of technology

Through this high-efficiency spindle cover bearing pressing tool, stable and efficient pressing of the bearings in the spindle cover is achieved, damage to the spindle cover is avoided, production efficiency is improved, and the positioning of each component is accurate, and production costs are reduced.

Abstract

The invention belongs to the technical field of bearing mounting equipment, and particularly relates to a high-efficiency spindle cap bearing press-fit jig which is provided with an upper press-holding mechanism, a middle fixing mechanism and a lower supporting press-holding mechanism, and a first press-holding part is stressed to overcome the elastic force of a first elastic element, so that the first press-holding part gradually moves into a first through hole along a first connecting part; soft pressing is carried out on the area, where a bearing is installed, outside the main shaft cover, and the main shaft cover is prevented from being damaged in the pressing process; the middle plate overcomes the upward elastic force of the second elastic element to gradually move downwards, so that the bearing in the main shaft cover is softly pressed into the main shaft cover, the bearing is gradually and slowly pressed into the inner side of the main shaft cover through the first pressure-bearing piece, the second pressure-bearing piece and the third pressure-bearing piece, the production efficiency is improved under the condition that the main shaft cover is not damaged, and the production cost is reduced. And each part is accurately positioned, and meanwhile, a plurality of bearings are pressed into the main shaft cover, so that the production cost is greatly saved.
