Problems solved by technology

The processing sequence of the existing ball-joint connecting rod is the overall electroplating after the blank is cut and formed, because the thickness of the coating layer cannot be accurately controlled in the electroplating process, and the surface roughness of the coating layer is relatively large, which may easily cause a mismatch between the size of the ball head and the ball socket, resulting in a and the double wear of the bushing, eventually leading to early failure and scrapping of the connecting rod assembly

Abstract

The invention discloses a ball connecting rod, a connecting rod assembly and a processing method of the ball connecting rod. The ball connecting rod is used for matching a ball socket. The ball connecting rod contains a ball which matches the ball socket, a connecting rod which is connected with the ball and has screw thread and a coating which is arranged on the outer surface of the connecting rod and is at least covered with screw thread. The processing method of the ball connecting rod comprises the following steps: S1, blanking is carried out to generate a blank with a ball and a connecting rod; S2, the connecting rod of the blank undergoes thread rolling to form a first part with screw thread; S3, the surface of the first part is electroplated to form a second part with a coating; S4, the second part is cut and processed, and the coating formed at the ball of the second part is at least removed to form a third part; and S5, the third part undergoes barreling and cleaning. According to the ball connecting rod manufactured by the above processing method, the ball has high machining precision and low roughness, the ball matches the ball socket greatly, and early failure of the connecting rod assembly is avoided.

Description

technical field [0001] The invention relates to a connecting rod assembly, in particular to a ball joint rod, a connecting rod assembly and a processing method for the ball joint rod. Background technique [0002] The car connecting rod is an auxiliary elastic component in the car suspension. Ball pins are often used at the connection of the connecting rod. Its function is to prevent excessive lateral roll of the body when turning, prevent the car from laterally tipping and improve ride comfort. sex. Now the main part of the connecting rod assembly is the connecting rod ball pin, and the quality of the ball pin directly affects the service life of the assembly. The processing sequence of the existing ball-joint connecting rod is the overall electroplating after the blank is cut and formed, because the thickness of the coating layer cannot be accurately controlled in the electroplating process, and the surface roughness of the coating layer is relatively large, which may eas...
