Milling device for crank connecting rod of auto parts

Abstract

The invention relates to the field of manufacturing of automobile parts, in particular to a milling device for an automobile part crank connecting rod. The milling device comprises a table, a loadingdevice, a fixing device, a conveying device, milling devices and an unloading device; a stand on which the conveying device, the milling devices and the unloading device are fixedly mounted is arranged on the table, the fixing device is mounted at the discharging port of the loading device, and the conveying device driving the fixing device to conduct horizontal reciprocating movement is mounted on the fixing device; the two sides of the conveying device are provided with the multiple milling devices which are oppositely arranged, and the side of the tail end of the conveying device is provided with the unloading device. The milling device can conduct multi-pass milling procedures on the crank connecting rod, can achieve automatic loading, can fix the crank connection rod which is being processed, and can achieve automatic unloading after processing is completed.

Description

technical field [0001] The invention relates to the field of auto parts manufacturing, in particular to a milling device for crank connecting rods of auto parts. Background technique [0002] The shape of the crank connecting rod is relatively complex, easy to deform, poor in rigidity, high in dimensional accuracy, positional accuracy and surface quality, and it is difficult to manufacture. The quality of the connecting rod manufacturing technology directly affects the performance and economic performance of the connecting rod, as well as the survival and development of an enterprise. With the development of production technology, the traditional manufacturing technology cannot meet the current production requirements gradually. The traditional end face milling of crankshaft and connecting rod is to mark and position first, use one end face of the crankshaft connecting rod as a reference, process the other side, and then use the processed surface as a reference to process th...

AI Technical Summary

Problems solved by technology

[0004] This patent does not consider the fixing mechanism during milling. When the workpiece is milled in the equipment, it is easy to jump out of the processing position due to vibration, thereby causing damage to the equipment, and the vibration of the workpiece during processing will also adversely affect the machining accuracy, and the crank The connecting rod is a casting or forging part, and the milling surface is very deep. The milling head alone is not enough to mill the double end faces of the crank connecting rod, and the required processing depth cannot be achieved.
