Problems solved by technology

[0003] The current hydraulic buffer is basically a single-degree-of-freedom hydraulic cylinder buffer, and due to structural reasons, its buffer direction is unidirectional, which can only achieve unidirectional impact buffering of the controlled object, but cannot track the controlled object. Continuous motion, not to mention the tension and compression cushioning requirements for multi-degree-of-freedom compound vibrations in special environments

Abstract

The invention discloses the multiple vibration hydraulic buffer based on parallel six-freedom platform. It comprises the butter fixing platform, six double-functional single-freedom hydraulic buffers, the buffer movable platform and the joint hinge. The buffer movable platform connects the controlled target; the fixing platform is equipped on the base or other fixing planes; the said six hydraulic buffers connect the movable and the fixing platforms through the hinge and support the movable platform to move six-dimensionally. The invention can bear the vibrations and the strikes from six directions at the same time, can track the continuous movement of the controlled target and provides a tight and ideal assembly scheme for the multi-freedom composite vibration buffer.

Description

technical field [0001] The invention relates to a hydraulic buffer system, in particular to a composite vibration hydraulic buffer based on a parallel six-degree-of-freedom mechanism. Background technique [0002] Hydraulic buffering is much superior to buffering methods such as spring and friction. It can not only absorb huge impact energy but also design buffering rules according to requirements, and work stably and reliably. At present, it is widely used in high-speed automated production lines, construction machinery transportation vehicles, light industry, and textile machinery. The installation of hydraulic buffers can increase output, prolong service life, optimize work and reduce noise. [0003] The current hydraulic buffer is basically a single-degree-of-freedom hydraulic cylinder buffer, and due to structural reasons, its buffer direction is unidirectional, which can only achieve unidirectional impact buffering of the controlled object, but cannot track the control...
