Abstract

This invention belongs to the field of machining technology and discloses an automatic machining device and method for automotive connecting rod kits. The machining device includes a base, a broach assembly, a slide plate, and a fixing assembly. The broach assembly includes a broach for machining mating teeth on a first workpiece and a second workpiece. The slide plate is vertically slidably mounted on the base and has an upper positioning post and a lower positioning semi-cylinder. The sleeve portion of the first workpiece is fitted onto the upper positioning post. The lower positioning semi-cylinder has a first positioning groove for engaging the first workpiece and a second positioning groove for engaging the second workpiece. The difference in the radial distance between the two positioning grooves on the lower positioning semi-cylinder is equal to the width of a single machining tooth of the broach. The fixing assembly includes a pressure clamp for pressing the first and second workpieces onto the lower positioning semi-cylinder. This machining device and method can simultaneously machine the mating teeth on the first and second workpieces and ensure good engagement between them, saving space and manufacturing costs.
