Abstract

The invention relates to an end shaft drilling device. The end shaft drilling device comprises a machine frame and a supporting table, wherein a triangular plate is connected to the machine frame, a cam is arranged below one end of the triangular plate, a rotating shaft is arranged below the cam, a rotating shaft is coaxially connected with a rotating disc, the rotating disc can be meshed with thecam, the rotating shaft is connected with a transverse shaft and a supporting shaft through a bevel gear, a supporting disc is fixedly connected to the top end of the supporting shaft, and a collecting box is rotationally connected to the bottom end of the supporting shaft, the other end of the triangular plate is connected with a first fixing block, and the bottom end of the first fixing block is connected with a first supporting plate, the first supporting plate is connected with a sliding rod, the other end of the sliding rod is connected with a drill bit, a supporting spring sleeves the sliding rod, the first fixing block is fixedly connected with a transverse plate, the other end of the transverse plate is connected with a second fixing block, the bottom end of the second fixing block is connected with a push rod, a water bag is fixedly connected to the supporting table, the water bag is connected with a water spraying pipe, and the water spraying pipe is connected with a spray head. According to the device, the problems that the drill bit needs to be moved in a drilling process and iron scraps are not easy to remove due to excessively high temperature are solved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a crankshaft end shaft drilling device. Background technique [0002] The crankshaft is the most important component in the engine. It bears the force transmitted by the connecting rod and converts it into torque through the crankshaft output and drives other accessories on the engine to work. The crankshaft is subjected to the joint action of the centrifugal force of the rotating mass, the periodically changing gas inertial force and the reciprocating inertial force, so that the crankshaft is subjected to the bending torsional load. [0003] The crankshaft is basically divided into an integral crankshaft and a combined crankshaft. Whether it is an integral crankshaft or a combined crankshaft, its basic components are mainly: end shaft, connecting rod journal, crank, crank throw and balance weight. The end shaft of the crankshaft usually needs to be drilled during the machi...
