Abstract

The invention discloses a clamp lifting type connecting rod grooving device. The clamp lifting type connecting rod grooving device mainly comprises a machine frame, a workbench, a backboard, a wire winding cylinder, an electrode wire, a grooving mechanism, a lifting mechanism and an adjustable anti-collision clamp; during use, a locking block is pushed backwards firstly, a connecting rod workpieceis installed on a clamp face board, then the locking block is released, the locking block abuts against a connecting rod under the action of a locking spring, so that effective centering of the connecting rod is ensured, and the connecting rod is prevented from shaking in the machining process; and then the lifting mechanism drives the adjustable anti-collision clamp to rise upwards, if the connecting rod collides with a U-shaped structure, the clamp face board can turn over, so that collision damage is reduced, if no collision occurs, the position of the grooving device is adjusted through afirst motor, so that the machining position of the U-shaped structure is determined; during machining, a left sliding block and a right sliding block are adjusted to move close to each other or awayfrom each other through the driving of a second motor, so that a cracking groove is machined. The clamp lifting type connecting rod grooving device further has the advantages of being simple in structure, convenient to operate and easy to implement.

Description

technical field

[0001] The invention relates to the technical field of wire electric discharge machining, in particular to a clamp lifting type connecting rod grooving equipment. Background technique

[0002] Automobile connecting rod is an important component of automobile engine, which has an important influence on the performance of the engine. The connecting rod expansion technology is to apply a horizontal directional breaking force inside the big end hole of the connecting rod through the state, so that the crack in the cracking groove expands rapidly until it breaks, and the rod cover and the rod body are separated. The rod body and the rod cover are combined through the concave-convex fracture surface, which increases the accuracy and reliability compared with the traditional fracture surface. The connecting rod expansion process can reduce the process by 60% at most, reduce the investment by 25%-35%, and save energy by 40%. Processing the cracking groove of the co...
