Description

Bearing frame positioning mechanism Technical Field The invention relates to the field of machining, in particular to a bearing seat positioning mechanism. Background Referring to fig. 1, a schematic structure of a bearing housing is shown. The bearing seat with the structure is of a rectangular block structure with a thickness, one end of the bearing seat is a connecting end, the other end of the bearing seat is a bearing assembly end, and the width of the connecting end is smaller than that of the bearing assembly end. The connecting end welding of bearing frame has the connection base plate, and the connection base plate extends along the width direction of bearing frame, and two extension ends surpass bearing assembly end length, thickness place side respectively, are provided with the bearing hole that runs through along the thickness direction on the bearing assembly end for the assembly bearing. When machining enterprises mill the side face where the length and the thickness of the bearing assembly end are located, as the extending end of the connecting substrate exceeds, if the bearing seat is directly clamped on a milling machine table, the side face where the length and the thickness of the bearing assembly end are located extends obliquely, and normal milling cannot be performed.
