Hydraulic intermittent motion mechanism

Abstract

The invention discloses a hydraulic intermittent motion mechanism, wherein, a rotating platform (1) is provided with a plurality of taper pin holes; the rotating platform (1) is tightly connected with a rotating column (2) and then arranged on a frame (8); the rotating platform (1) and the rotating column (2) moves relative to the frame (8); a pin hydraulic cylinder (7) is fixed on a swinging rod (3); the other end of the swinging rod (3) is hinged with a connecting rod (4); the swinging rod (3) and the frame (8) form a prismatic pair to ensure the rigidity of the swinging rod under the action of the pin hydraulic cylinder; the other end of the connecting rod (4) is hinged with a sliding block (6); the sliding block (6) is arranged on the frame (8) and slides on the frame, and the sliding block (6) is fixedly connected with a piston rod of an active hydraulic cylinder (5); and the active hydraulic cylinder (5) is fixedly connected with the frame (8). In the invention, the sliding block and the swinging rod are organically combined with hydraulic transmission so as to realize connection and disconnection between the swinging rod and the rotating platform, thus achieving intermittent circular motion of the rotating platform, solving the problem of heavy load that the common intermittent mechanism can not adapt to, and meeting the demand of automatic production.

Description

technical field [0001] The invention relates to a motion mechanism, in particular to a hydraulic intermittent motion mechanism. Background technique [0002] Commonly used intermittent circular motion mechanisms include ratchet mechanisms, sheave mechanisms, and incomplete gear mechanisms. These intermittent circular motion mechanisms have their own characteristics in specific applications, but they all have certain shortcomings; There is a large impact and noise, and the motion stability is poor, so it is often used in occasions where the speed is low, the load is small, and the motion accuracy is not high; the driven wheel of the incomplete gear mechanism has a large vibration when entering and disengaging. Impact and dynamic characteristics are poor, so it is only suitable for low-speed and light-load occasions. In engineering practice, when intermittent circular motion needs to drive large loads, the above-mentioned commonly used mechanisms obviously cannot meet their u...
