Abstract

The invention discloses a large-load liftable workbench which comprises a base supporting plate and a workbench panel. The upper part of the base supporting plate is provided with four first guide roller support seats, the four first guide roller supporting seats are respectively internally provided with a first guide roller, four second guide roller supporting seats are arranged at the lower part of the workbench panel, and the four second guide roller supporting seats are respectively internally provided with a second guide roller. The base supporting plate is further provided with an air cylinder, a rail pushing rod is fixed on the air cylinder, the two ends of the rail pushing rod are respectively fixedly provided with an abnormal guide rail, and the abnormal guide rails are arranged between the first guide rollers and the second guide rollers. The large-load liftable workbench disclosed by the invention is a simple cam mechanism, and the support of the large-load liftable workbench is a rigid support with excellent bearing capability; in addition, according to the large-load liftable workbench disclosed by the invention, the mechanism is simple and is convenient to maintain; the performance is stable and reliable; the precision depends on the precision of a workpiece and is controllable; the machining difficulty is small, the production is convenient, the manufacture cost is low and the workbench is easy to bear.

Description

technical field [0001] The invention designs a working platform in the machinery industry, and in particular relates to a large-load liftable working platform. Background technique [0002] In the current machinery industry, liftable working platforms are roughly divided into motors, ball screw drive mechanisms, cylinders, connecting rod drive mechanisms, and large cylinder direct drive mechanisms. The driving mechanism of the motor plus ball screw has smooth movement and good controllability. Its accuracy depends on the accuracy of the ball screw and the accuracy of the motor, and its load capacity can only be determined by the power and torque of the motor. The applicability is relatively Wide, but the cost is relatively high. The lifting platform mechanism combined with cylinder and connecting rod has a simple mechanism and flexible action. The disadvantage is that the critical point in the actual use process (the three rotation axes of the two connecting rods are coplan...
