Double-cam universal rotary table

Abstract

The invention provides a double-cam universal rotary table. The rotary table comprises a base, a mandrel, a push rod frame and a workbench, one end of the mandrel is fixedly connected with the base through a nut, the push rod frame sleeves the middle of the mandrel, the outer side, between the base and the push rod frame, of the mandrel is sleeved with a first cam and a second cam, the first cam is connected to the inner side of the second cam in a sleeved mode, the positions, on the inner side of the base, of the first cam and the second cam are provided with a first turbine mechanism and a second turbine mechanism respectively, two first push rods and two second push rods are uniformly sleeved on the position, close to the periphery, of the push rod frame, the other end of the mandrel isrotationally connected with the workbench through a spherical joint, and the other ends of the first push rods and the second push rods abut against the inner side face of the workbench correspondingly. According to the rotary table, through the synergistic effect of the turbine mechanisms and a boss, the problem that an existing rotary table cannot be independently rotated and controlled duringpitching and horizontal lateral rotation, the moving structure has dead points, so that the use of linkage control of rotation is influenced is solved.

Description

technical field [0001] The invention belongs to the technical field of universal turntables, and in particular relates to a double-cam universal turntable. Background technique [0002] The universal turntable refers to the mechanical structure that the worktable can be rotated to any position and fixed at that position. It is widely used in machining, and the finished universal turntable is also widely used in the daily monitoring industry. [0003] The existing turntable cannot be independently rotated and controlled in the pitch and horizontal and lateral rotations, and the motion structure has a dead point, which affects the use of the linkage control of the rotation. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a double-cam universal turntable for the above-mentioned deficiencies in the prior art, which is used to solve the problem that the existing turntable proposed in the above background technology ca...
