Description

Technical Field

[0002] The inner support point of the bearing is the shaft, and the outer support is what is commonly called the bearing seat. During the production and processing of the bearing seat, it is often necessary to perform hole drilling on its surface. When the bearing is subjected to inclined hole processing, an angle positioning device is required to assist the rotation of the workpiece. Such equipment is not only expensive, but also has low operating efficiency and certain requirements for system control. This leads to huge investment in the CNC drilling machine used, but the processing efficiency is not high. Since a bearing can use different bearing seats, and a bearing seat can also use different types of bearings, there are many varieties of bearing seats. The Chinese patent announcement number is: CN111375800A discloses "A device for processing circumferential inclined holes in a bearing seat". The patent can facilitate the one-time clamping and positioning of the seat body through the arrangement of a machining center, a dividing head and a chuck. The inclination angle of the chuck can be rotated by the dividing head, and the rotation angle of the chuck can be automatically controlled by the rotating spindle of the machining center, so as to facilitate the processing of multiple inclined holes on the same bearing seat, thereby improving the processing efficiency of the inclined holes on the bearing seat while meeting the processing accuracy requirements. The arrangement of the mounting ring, the positioning hole, the positioning pin and the material reduction groove can improve the relative installation accuracy of the seat body, thereby facilitating the effect of improving the processing accuracy of the inclined holes.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions. The sentence "includes an element defined by... does not exclude the existence of other identical elements in the process, method, article or device including the element".
