Bearing press-fitting automatic feeding device and bearing press-fitting method

Abstract

The invention belongs to the technical field of bearing assembly, and particularly discloses a bearing press-fitting automatic feeding device and a bearing press-fitting method. A pushing mechanism pushes a positioning cylinder to stretch forwards until a front-end positioning pin is inserted into a bearing seat pin hole for accurate alignment; if the position deviates, forced correction can be carried out through the floating connection relation of clearance fit of an elastic connecting block, a through hole of a mounting seat and an equal-height screw; a bearing in a feeding groove falls into the positioning cylinder from a window, and whether the bearing falls in place or not is detected through a correlation photoelectric sensor; and a platform pushes the mounting seat forwards and pushes a press-fitting piece to press the bearing into the bearing seat, and the inner diameter of the positioning cylinder always limits the outer diameter of the bearing to be press-fitted to maintain press-fitting positioning in the press-fitting process. According to the scheme, the problems that in the existing bearing press-fitting process, a bearing feeding device and a press-fitting device are independently separated, so that the structure is complex, the cost is high, the occupied space is large, and bearing posture keeping is not facilitated are solved, and the bearing press-fitting automatic feeding device is low in cost, compact and integrated.

Description

technical field [0001] The invention belongs to the technical field of bearing pressing assembly, and in particular relates to an automatic feeding device for bearing pressing and a bearing pressing method based on the device. Background technique [0002] Bearings are common components of mechanical devices, and the common installation methods mainly include press-fitting and shrink-fitting. For press-fit assembly, when the bearing is pressed into the assembly hole of the bearing seat, it is necessary to align the bearing with the assembly hole, and the bearing must not be deflected during the press-in process, otherwise the press-in will not be possible or the press-in will not be in place. Bearing press-fitting is generally more suitable for the situation where the assembly hole is vertically facing upwards. In this case, the press-fitting equipment is less restricted, and the press-fitting process does not even require additional posture-maintaining auxiliary tools. For ...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that it is difficult to mount the bearing on the side, and the integration of a separate bearing feeding device is low
