Abstract

The invention provides a high precision dual transmission mechanism comprising a main shaft, a pair of connecting rods, a pair of hinge pins and a movable module. The connecting rods extend toward themovable module from the both sides of the main shaft, and one end of each connecting rod is connected with the main shaft; and the other end of the connecting rod is connected with the movable modulethrough the corresponding hinge pin, and each hinge pin is of a cylindrical structure; and the connecting rods are rotated around the hinge pins. According to the high precision dual transmission mechanism, the shortcomings of the prior art are overcome, and the machining precision is improved; the technological requirements which need to reach during machining of precision accessories are met, so that the rejection rate of processed product is reduced; an original structure is not changed in the method greatly; the manufacturing cost of the mechanism is reduced, and the assembly or fabrication efficiency is improved; a multi-segment main shaft is replaced with a single shaft, so that the manufacturing synchronism is improved; and the product difference caused by non-synchronization of the multi-segment structure is avoided effectively.

Description

technical field [0001] The invention relates to the field of pressure machinery, in particular to a high-precision dual transmission mechanism. Background technique [0002] Presses (including punch presses and hydraulic presses) are versatile presses with exquisite structures. With the characteristics of wide application and high production efficiency, the press can be widely used in cutting, punching, blanking, bending, riveting and forming processes. Processed into parts by applying intense pressure to a metal blank to cause the metal to plastically deform and fracture. When the mechanical press is working, the motor drives the large pulley (usually doubled as a flywheel) through the V-belt, and drives the crank slider mechanism through the gear pair and clutch, so that the slider and the punch go down in a straight line. After the forging work of the mechanical press is completed, the slider moves upward, the clutch is automatically disengaged, and at the same time the...
