Problems solved by technology

At the same time, considering the axial positioning of the small end of the connecting rod, it is required that the end face of the small end of the connecting rod must be finished. In general, it needs to be milled. However, because the small end is at the end of the connecting rod, the shape is irregular, making the processing more difficult.

Abstract

The invention discloses an end face milling clamping device of an automobile engine connecting rod small end. The end face milling clamping device comprises a bottom plate (8), a locating assembly, a clamping assembly and a supporting block (1). The locating assembly and the clamping assembly are arranged at the two ends of the bottom plate (8) correspondingly. A large end round hole of a connecting rod (13) is formed in the locating assembly in a sleeving manner, and the clamping assembly clamps the small end of the connecting rod (13). The supporting block (1) is arranged between the connecting rod (13), and the supporting block (1) and the bottom plate (8) are mounted through interference or transition fit, so that the top end of the supporting block (1) abuts against the bottom end of the small end of the connecting rod (13). The end face milling clamping device of the automobile engine connecting rod small end is simple in structure, convenient to use, high in machining efficiency and good in machining effect.

Description

technical field [0001] The invention relates to a milling processing device, in particular to a clamping device for milling and processing the small end face of an automobile engine connecting rod. Background technique [0002] In the crank linkage mechanism of an automobile engine, the connecting rod is generally composed of three parts: the small end of the connecting rod, the shaft and the large end of the connecting rod. The small end of the connecting rod is connected with the piston pin and is sleeved in the piston. When working, the small end of the connecting rod swings and reciprocates along the piston pin in the piston, which requires a gap between the end face of the small end of the connecting rod and the inside of the piston. At the same time, considering the axial positioning of the small end of the connecting rod, it is required that the end face of the small end of the connecting rod must be finished. In general, it needs to be milled. However, because the sm...
