Problems solved by technology

However, the current cylindrical grinding machines for crankshafts generally use automatic equipment such as fully enclosed protective covers, follow-up center frames, and flip radial gauges. The commonly used crankshaft loading and unloading methods rely on manual loading and unloading or controlled crane loading and unloading, which is not only labor-intensive , and often scratches the surface of the crankshaft

Abstract

The invention relates to an automatic loading and unloading device aiming at a crankshaft, comprising a left swinging bracket and a right swinging bracket, wherein, the swinging brackets are composedof a front swinging arm, a rear swinging arm and a workpiece bracket; two sides of the workpiece bracket are respectively hinged with upper ends of a left swinging arm and a right swinging arm, and lower ends of the left swinging arm and the right swinging arm are respectively connected with a front rotating shaft and a rear rotating shaft; the front rotating shaft and the rear rotating shaft arerotatablely connected with a frame by a bearing; and one of the front rotating shaft and the rear rotating shaft is a driving shaft, the driving shaft is connected with a hydraulic drive mechanism, and the hydraulic drive mechanism is provided with a control circuit. In the invention, a hydraulic cylinder of the hydraulic drive mechanism drives the swinging brackets to swing for automatically loading and unloading, thus improving working efficiency, reducing labor intensity and avoiding scratch possibility on a workpiece during a manual loading and unloading process.

Description

technical field [0001] The invention relates to an automatic loading and unloading device, in particular to an automatic loading and unloading device for crankshafts, which belongs to the field of metal cutting and can be used for loading and unloading workpieces of cylindrical grinding machines for crankshaft processing and other machine tools. Background technique [0002] In order to meet the needs of the new industrial structure, especially the rapid expansion of the modern automobile manufacturing industry, the requirements for the efficiency of the corresponding machine tools are constantly increasing. However, the current cylindrical grinding machines for crankshafts generally use automatic equipment such as fully enclosed protective covers, follow-up center frames, and flip radial gauges. The commonly used crankshaft loading and unloading methods rely on manual loading and unloading or controlled crane loading and unloading, which is not only labor-intensive , and of...
