A cutting machine tool for crankshaft connecting rod production

Abstract

The invention provides a cutting machine tool for crankshaft connecting rod production. The cutting machine tool comprises a compartment body, a sawing machine, a clamping device, a numerical control main unit, a hopper and a material box, wherein the compartment body is provided with a sawing machine operation window and a clamping operation window; the clamping device comprises a support, a cross sliding table, a cylinder, a lever structure, a pressing block, a limiting block and a rotatable servo motor; both a Y-axis sliding rail and an X-axis sliding rail of the cross sliding table are arranged horizontally, and are connected through a sliding block; a Y-directional screw rod structure and a Y-directional servo motor are arranged in the Y-axis sliding rail; an X-directional screw rod structure and an X-directional servo motor are arranged in the X-axis sliding rail; the lever structure and the cylinder are fixed above the X-axis sliding rail; two ends of a lever are respectively connected with a telescopic rod of the cylinder and the pressing block in a hinged manner; the limiting block is arranged on the X-axis sliding rail and is connected with the rotatable servo motor through a transmission mechanism; and the numerical control main unit is electrically connected with the rotatable servo motor, the Y-directional servo motor and the X-directional servo motor. The cutting machine tool for crankshaft connecting rod production reduces the labor intensity of a worker, eliminates the potential safety hazards and guarantees the quality of a workpiece.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a cutting machine tool used in the production of crankshaft connecting rods. Background technique [0002] Crankshaft-connecting rod mechanism is a transmission mechanism widely used in engines and motors. It is used to realize the power transmission between the linear reciprocating motion of the piston and the rotary motion of the crankshaft. The connecting rod is a rod-shaped rod directly connected between the piston and the crankshaft. The structure generally includes a small end, a shaft and a large end. The small end of the connecting rod is used to connect the piston pin, the large end of the connecting rod is used to connect with the crank pin of the crankshaft, and the shaft is used to connect the small end and the large end. The large head is designed as a split type, and the separated part is the connecting rod cover. During production, the connecting rod body an...

Problems solved by technology

Since the connecting rod body and the connecting rod cover mostly adopt the die-casting process, in order to improve efficiency, multiple connecting rod cores are usually set in the mold, so that multiple connecting rod workpieces can be die-casted at one time and these multiple workpieces need to be connected through reserved connecting rods. For an integrated blank, after the blank is taken out from the mold and cooled, the workpiece needs to be cut off from the blank. In the prior art, workers mostly use connecting rods to cut the blank. The disadvantage is that on the one hand Workers are prone to fatigue if they hold the blank for a long time. The labor intensity of the workers is high, and there are also potential safety hazards. At the same time, it is difficult to ensure the accuracy of the cut manually, which may easily cause unqualified waste parts.
