  • the invention relates to the technical field of bearing assembly, in particular to fully automatic assembly equipment and a method for thin-wall angular contact bearing rings.
  • Bearings are an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. According to the different friction properties of the moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, their radial dimensions, vibrations and noise are larger, and their prices are also higher.
  • Angular contact ball bearings are a type of bearing that can withstand radial and axial loads at the same time. They can work at higher speeds. The larger the contact angle, the higher the axial load capacity. High-precision and high-speed bearings usually take a contact angle of 15 degrees. Under the action of axial force, the contact angle will increase. Thin-walled bearings achieve an extremely thin bearing section, and also achieve miniaturization and lightweight of the product.

Description

薄壁角接触轴承套圈的全自动组装设备及方法 技术领域
本发明涉及轴承组装技术领域，具体是薄壁角接触轴承套圈的全自动组装设备及方法。
背景技术
轴承是当代机械设备中一种重要零部件。它的主要功能是支撑机械旋转体，降低其运动过程中的摩擦系数，并保证其回转精度，按运动元件摩擦性质的不同，轴承可分为滚动轴承和滑动轴承两大类。其中滚动轴承已经标准化、系列化，但与滑动轴承相比它的径向尺寸、振动和噪声较大，价格也较高。角接触球轴承是轴承的一种，角接触球轴承可同时承受径向负荷和轴向负荷。能在较高的转速下工作。接触角越大，轴向承载能力越高。高精度和高速轴承通常取15度接触角。在轴向力作用下，接触角会增大。薄壁型轴承实现了极薄型的轴承断面，也实现了产品的小型化、轻量化。轴承的润滑方法，分为脂润滑和油润滑。
轴承一般由内圈、外圈、滚动体和保持架四部分组成，内圈的作用是与轴相配合并与轴一起旋转；外圈的作用是与轴承座相配合，起支撑作用；滚动体是借助于保持架安装在内圈和外圈之间，其形状、大小和数量直接影响着轴承的使用性能和寿命；保持架能使滚动体均匀分布，防止滚动体脱落，引导滚动体旋转，起润滑作用。高速轴承的装配是先将内圈、保持架和滚动体组装成内圈组件，然后再将该内圈组件与外圈进行装配。
现有的薄壁角接触轴承套圈组装设备在对薄壁角接触轴承进行组装时，往往使用柱状定位件对内圈组件进行定位，但为了便于内圈组件的脱离，内圈组件与柱状定位件间的配合方式往往采用间隙配合，该种定位方式保证内圈组件脱离的 便捷性，但间隙配合使得内圈组件定位精确度降低，无法同时保证内圈组件脱离的便捷性和定位的精确性。
发明内容
本发明的目的在于提供薄壁角接触轴承套圈的全自动组装设备及方法，用于解决现有的薄壁角接触轴承套圈组装设备在对薄壁角接触轴承进行组装时，往往使用柱状定位件对内圈组件进行定位，但为了便于内圈组件的脱离，内圈组件与柱状定位件间的配合方式往往采用间隙配合，该种定位方式保证内圈组件脱离的便捷性，但间隙配合使得内圈组件定位精确度降低，无法同时保证内圈组件脱离的便捷性和定位的精确性的技术问题。
本发明的目的可以通过以下技术方案实现：
