Rotating working table

Abstract

The invention discloses a rotating working table, and belongs to the field of low-voltage electric facilities. The rotating working table comprises a rotating base, a rotary central spindle and a loading plate, a rolling bearing is arranged on a radial nested surface between the rotating base and the rotary central spindle, a plane bearing is arranged on an axial end plane between the rotating base and the rotary central spindle; the rotating working table further comprises a locking mechanism which is composed of a limiting ring, a pressing level, a movable rod, a pedal, a springback part and a fixed block. According to the rotating working table, friction of original two sleeve end planes is changed into thrust ball bearing rolling friction, friction of inner and outer nested surfaces of two sleeves are is changed into rolling friction of a deep groove ball bearing, and then rotation is smoother; even though a rotating table body rotates at a high load for a long time under large mass pressure, no abnormal sound or shake exists, the use effect is better, and the service life is greatly prolonged; the rotating working table has the advantages of being simple in structure, few in parts, convenient to assemble, high in reliability, capable of effectively lowering the cost and the like.

Description

technical field [0001] The invention belongs to the technical field of low-voltage electrical facilities, and in particular relates to a rotary workbench. Background technique [0002] At present, the main structure of most of the rotary tables on the market is that two large-diameter circular tubes are nested together after finishing. Its defects are: the inner and outer walls of the two sleeves and the outer tube surface will rub against each other when rotating, and when rotating under high load for a long time, the inner and outer surfaces of the two sleeves will wear more and more, and the rotation will not be smooth due to the large gap, resulting in Abnormal noise and shaking will greatly reduce its service life. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a rotary table with simple structure and convenient operation in order to solve the above problems, so as to make the rotation smoother, even if the rota...
