Automatic production line material transmission abnormality monitoring method and automatic honing line

Abstract

The invention discloses an automatic production line material transmission abnormality monitoring method and an automatic honing line. According to the basic principle of the monitoring method, marking is conducted at each station, the theoretical variable is automatically updated according to the station material state, material transmission abnormality of the corresponding station is found according to the difference of the actual variable and the theoretical variable, a user can find the transmission abnormality of workpieces on the automatic honing line in time, and the abnormal station isaccurately positioned. The automatic honing line based on the material transmission abnormality monitoring method comprises a plurality of material detection switches, an automatic line displacementdrive sensor and a PLC, wherein the material detection switches are arranged along the automatic line and correspond to the stations. The accurate and efficient material transmission monitoring methodis achieved, original automatic line monitoring hardware is basically not changed, the upgrading cost is low, operation is convenient and reliable, and the risk of mistaken machining of the workpieces on the automatic line is eliminated; and the automatic honing machining efficiency is improved, and the requirement of automatic assembly lines in the fields of honing and the like for efficient machining is met.

Description

technical field [0001] The invention relates to an automatic production line control technology, in particular to an automatic production line material transmission abnormality monitoring method and an automatic honing line. Background technique [0002] In the field of mechanical processing, honing is to use one or more oil stones installed on the circumference of the honing head, under the action of radial expansion of the expansion mechanism, and press it against the hole wall of the workpiece to produce a certain surface contact. At the same time, the workpiece is kept still by the workpiece clamping device, and the honing head is rotated and reciprocated to realize honing processing. This process is widely used in the processing of thin-walled pipe sleeves. [0003] In recent years, in order to improve the efficiency of honing processing, various innovations and attempts have been made by those skilled in the art, such as an automatic honing machine tool disclosed in Ch...

Problems solved by technology

However, in actual production, when the switch line of material detection is damaged, even if the workpiece reaches the processing station, the system will not detect the signal of material, and then the workpiece will not be processed, which will affect the operation of the entire production line

Since the existing automatic line only collects and uses the signal of the material detection switch, and does not judge the abnormal situation of the material detection switch signal, when the signal of the material detection switch is abnormal, it will send a wrong signal, resulting in the failure of the automatic line. The processing is abnormal, so the existing automatic line has the risk of wrongly processing the workpiece, which seriously affects the quality and efficiency of automatic honing processing
