Bolt screwing machine for automobile engine flywheel

Abstract

The invention discloses a bolt screwing machine for an automobile engine flywheel. The bolt screwing machine comprises a base. A lifting installing frame is fixed to the middle of the base. A lifting device is arranged on the lifting installing frame. A first machine base and a second machine base are fixed to the two sides of the base respectively. A first supporting plate is fixed to the first machine base. A first sliding rail cushion plate and a second sliding rail cushion plate are arranged on the two sides of the first supporting plate respectively. A first air cylinder is installed in the middle of the first supporting plate. Linear sliding rails are arranged on the first sliding rail cushion plate and the second sliding rail cushion plate respectively. A first installing plate is in sliding connection with the first sliding rail cushion plate and the second sliding rail cushion plate. A first air cylinder push plate is connected to the bottom of the first installing plate. One side of the first air cylinder push plate is fixed to the first installing plate. The other side of the first air cylinder push plate is connected with a first floating connector fixed to an output shaft of the first air cylinder. The bolt screwing machine is high in automation degree and has high pertinence; and in addition, the installing error is reduced, and the part installing precision and the part production efficiency are improved.

Description

technical field [0001] The invention relates to an auxiliary equipment for installing auto parts, in particular to a bolt tightening machine for the flywheel of an automobile engine, belonging to the technical field of mechanical equipment. Background technique [0002] For a general four-stroke engine, work is done once every four piston strokes, that is, only the power stroke does work, and the three strokes of exhaust, intake and compression all consume work. Therefore, the external output torque of the crankshaft on the engine changes periodically, and the crankshaft speed is also unstable. In order to improve this situation, a flywheel is installed at the rear end of the crankshaft. The flywheel is a disc-shaped part with a large moment of inertia. It acts like an energy storage. Its main function is to store the energy and inertia outside the power stroke of the engine. When the engine speed increases, the kinetic energy of the flywheel increases. At this time The f...
