Automatic piston assembling robot and method

Abstract

The invention provides an automatic piston assembling robot. A piston comprises a piston head, a piston rod and a piston pin, a first connecting hole is formed in the piston head, a second connecting hole is formed in the piston rod, the piston pin is inserted into the first connecting hole and the second connecting hole so that the piston rod can be hinged to the piston head. The robot comprises a machine frame, wherein the machine frame comprises a horizontally-placed mounting plate and a plurality of supporting legs arranged on the lower surface of the mounting plate, and the supporting legs support the mounting plate; a piston head feeding mechanism which is arranged on the machine frame and used for feeding a piston head to be assembled to an assembly station; a piston rod feeding mechanism which is arranged on the machine frame and used for feeding a piston rod to be assembled to the assembly station, inserting the end, provided with a second connecting hole, of the piston rod into the piston head located at the assembly station and aligning the first connecting hole with the second connecting hole; and a piston pin feeding mechanism which is arranged on the machine frame and used for feeding a piston pin to the assembly station and inserting the piston pin into the first connecting hole and the second connecting hole located in the assembly station. The robot can achieve automatic assembly of the piston.

Description

technical field [0001] The invention relates to piston assembly technology, in particular to a piston pin automatic assembly robot and an assembly method. Background technique [0002] The piston is the "heart" of the automobile engine. It bears alternating mechanical loads and thermal loads. It is one of the key components in the engine with the worst working conditions. The function of the piston is to bear the gas pressure and transmit it to the connecting rod through the piston pin. The crankshaft rotates, and the top of the piston is also part of the combustion chamber; [0003] The piston includes a piston head and a piston rod, which are assembled and connected by a piston pin. The traditional piston mainly relies on manual operation, and the assembly efficiency is relatively low. During the assembly process, the depth of the piston pin is not easy to control, and often occurs The case where the pin is installed too deep. Contents of the invention [0004] In orde...
