Elevation-adjustable bearing block supporting structure

The invention relates to a bearing block supporting structure and particularly relates to an elevation-adjustable bearing block supporting structure comprising a mounting bracket, an arc-surfaced upper slide block, a mounting bolt and a locating pin; the arc-surfaced upper slide block supports against the top of the mounting bracket through an arc-surfaced left slide block and an arc-surfaced right slide block which are matched with the arc surface of the arc-surfaced upper slide block; the arc-surfaced left slide block and the arc-surfaced right slide block are in threaded connection with adjusted screws; a cushion block is arranged below the mounting bracket; the arc-surfaced upper slide block is connected and fixed together with the mounting bracket through a bolt; the elevation of the arc-surfaced upper slide block is finely adjusted through the matching of the arc surface, the positions of the arc-surfaced left slide block and the arc-surfaced right slide block are adjusted through the adjusted screws, and fixation is performed by using the locating pin after the elevation is adjusted; the mounting bracket is fixedly arranged on a mounting table-board by using the mounting bolt; and the elevation of a bearing block can be greatly adjusted by the cushion block. The elevation-adjustable bearing block supporting structure is reasonable in structural design, simple and convenient in operation, high in adjusting height, capable of saving time and labor, convenient, high in speed and low in cost.
