A piston circlip installation machine and its operating method

Abstract

The invention discloses a piston clamp spring installing machine. The piston clamp spring installing machine comprises a material tidying mechanism, a discharging mechanism, a material pushing mechanism, a clamp spring installing mechanism and a positioning mechanism. The clamp spring installing mechanism comprises a positioning piece and a push piece. The push piece comprises an upper part body and a lower part body. The upper part body comprises a plurality of movable bodies. When the upper part body stretches into the positioning piece, a gap between every two adjacent movable bodies is shrunk after being extruded by the positioning piece. A groove for a clamp spring to stretch is formed in the side wall of the positioning piece, and after the clamp spring is arranged in a hollow part of the positioning piece, the clamp spring moves and is shrunk along with the push piece till the clamp spring disengages from the positioning piece and is pushed into a clamp spring installing groove.The groove is right opposite to the material pushing mechanism, the clamp spring installing groove is formed in an installing hole of a piston, and the upper end face of the positioning piece is located below the installing hole. The invention further discloses an operation method of the piston clamp spring installing machine. According to the piston clamp spring installing machine and the operation method of the piston clamp spring installing machine, the structure is simple, feeding is convenient, automatic clamp spring installation is achieved, the installation position is accurate, the clamp spring is uniform in stress and cannot be damaged, the labor cost is saved, and the installation efficiency is high.

Description

technical field [0001] The invention belongs to the field of auxiliary installation of piston components, and in particular relates to a piston circlip installation machine and an operation method. Background technique [0002] The piston is an important part for reciprocating movement. It is connected to the connecting rod through a circlip. During assembly, the end of the e-shaped circlip is usually manually clamped with pliers and other tools, inserted into the circlip installation slot obliquely, and rotated to fit the entire piston. The circlip is set in the installation groove, and the circlip can be smoothly inserted due to the external force applied by the pliers, which will cause certain damage to the circlip, and its stress point is prone to breakage during work, reducing the service life of the entire piston, and The labor cost is high, the assembly efficiency is low, and the production cost is increased. Contents of the invention [0003] In order to overcome ...

[0002] The piston is an important part for reciprocating movement. It is connected to the connecting rod through a circlip. When assembling, the end of the e-shaped circlip is usually manually clamped with pliers and other tools, inserted into the circlip installation slot obliquely, and rotated to fit the entire piston. The circlip is set in the installation groove, and the clamp can only be inserted smoothly by bending the circlip with an external force, which will cause certain damage to the circlip, and its stress point is prone to breakage during work, reducing the service life of the entire piston, and High labor costs, low assembly efficiency, and increased production costs
