Rotary bearing platform device

Abstract

The invention discloses a rotary bearing platform device. The rotary bearing platform device comprises a base, a bearing platform and a clamp structure, wherein the bearing platform is arranged on thebase, and the clamp structure is arranged on the bearing platform. A cavity is arranged in the base, wherein the top face of the cavity is open. A cylindrical rod is fixed to the center of the bottomface of the bearing platform. One or more guiding protruding blocks are uniformly arranged on the inner wall of the cavity. The surface of the cylindrical rod is provided with a spiral guiding groove. The guiding protruding blocks are located in the spiral guiding groove. A lifting air cylinder is arranged between the bottom end of the cylindrical rod and the bottom wall of the cavity. A round hole is formed in the top end of a piston shaft of the lifting air cylinder. The top face of the piston shaft of the lifting air cylinder is provided with a disc. A rotating rod is arranged on the bottom face of the disc and connected into the round hole through a bearing. The disc is fixed to the bottom face of the cylindrical rod. The rotary bearing platform device is reasonable in structural arrangement and convenient and fast to operate; errors caused by the rotation inertia and the response time difference can be effectively reduced; machining precision and machining efficiency can be improved conveniently; and the rotary bearing platform device is good in application stability and high in practicability.

Description

Technical field [0001] The invention belongs to the technical field of workpiece processing equipment, and specifically relates to a rotating bearing platform device. Background technique [0002] In the process of dividing and processing, a rotating platform structure is required. The structure of the prior art is mainly composed of a main body, a bearing fixing seat, a seat body and an accommodation space, which is driven by a motor when in use, although it can realize a rotary drive operation , But in actual use, when the motor rotates to the required angle, due to the rotational inertia of the output turntable itself and the difference in response time, the output turntable cannot stop immediately, resulting in a significant error in the actual division angle of the output turntable, affecting subsequent Split processing, so applicability and practicality are limited. Summary of the invention [0003] The purpose of the present invention is to provide a rotary bearing platfor...

[0002] In the process of split processing, a rotating platform structure is required. The structure of the prior art is mainly composed of a body, a bearing fixing seat, a seat body and an accommodation space. It is driven by a motor when in use, although it can realize the rotary driving operation , but in actual use, when the motor rotates to the required angle, due to the rotational inertia of the output turntable itself and the response time difference, the output turntable cannot stop immediately, resulting in an obvious error in the actual division angle of the output turntable, affecting the subsequent Partial processing, so the applicability and practicality are limited
