[0002] The camshaft is an important component in the engine. According to the number of camshafts, it can be divided into single overhead camshaft and double overhead camshaft. Single overhead camshaft uses a camshaft on the cylinder head, and multiple cams are fixed on the camshaft to drive the intake and exhaust valves. Before installing the cam, it is necessary to drill positioning holes on the camshaft, which requires the use of drilling equipment.

[0003] The existing camshaft punching device is composed of X-axis and Y-axis guide rails, a clamp and four sets of motors. The output ends of the four sets of motors are equipped with drill bits, and the functions of the drill bits are drilling, reaming, countersinking and reaming respectively. The camshaft punching device is equipped with relatively more motors, which increases the manufacturing cost of the camshaft punching device and is not conducive to lightweight production of enterprises.
