Abstract

The present invention relates to a double-link overturning platform, which comprises an overturning platform top and an overturning system driving the overturning platform top, and wherein, the overturning system is composed of a platform top pitching mechanism and a platform top turning mechanism. The platform top pitching mechanism consists of a bench, two main motors, two decelerators, two couplings, two fixed seats, four fixed hinges, two small gears, two big gears, two big gear steady bearings, two lower link hinges, two links, two upper link hinges, a coordinating rod, a coordinating rod hinge, an overturning bench connecting seat, an overturning bench and two upper bench hinges. The platform top turning mechanism consists of a platform top rotating motor, a small platform top rotating gear, a large platform top rotating gear, a rotating platform top and a main shaft. The present invention utilizes the driving of the main motors and the platform top rotating motor to realize the overturning movement of a workpiece on the rotating platform top, the structure is simple, the platform top pitching mechanism has a force-increasing effect, the self-locking protection can be realized at an ultimate overturning position, and the present invention can realize the overturning of large-tonnage workpieces.

Description

technical field [0001] The invention relates to a double-link turning table, which is used in conjunction with a large numerically controlled boring and milling machine and the like, and can realize five-axis motion during numerically controlled machining, and belongs to the technical field of numerically controlled equipment in mechanical engineering. Background technique [0002] The turning table is one of the basic tools for multi-axis CNC machining. It is an important equipment for multi-axis CNC machining when used in conjunction with large-scale CNC boring and milling machines. The turning table needs to realize the two basic movements of pitching and rotating of large workpieces. The body structure of the turning table is mainly composed of two relatively independent parts, the pitch and the rotation, which are driven by a motor or a hydraulic system. The main transmission structure of the existing overturning table mainly adopts a large gear transmission form. Aft...
