Spindle running equipment and spindle running detection mechanism thereof

Abstract

The invention relates to spindle running equipment and a spindle running detection mechanism thereof. The equipment comprises a machine tool body, a programmable logic controller (PLC), a spindle motor, a power head spindle and the spindle running detection mechanism, wherein the spindle motor and a machine tool electronic control system are electrically connected; a main belt pulley is arranged at the power output end; a slave belt pulley is arranged at the power input end of the power head spindle; and the main belt pulley and the slave belt pulley are connected through a belt. The spindle running detection mechanism comprises a coded disc, a sensor fixing support and an inductive contactless sensor, wherein the coded disc is arranged at the power input end of the power head spindle; thecoded disc is located on one side of the axial direction of the slave belt pulley; the coded disc and the slave belt pulley are coaxially arranged; the sensor fixing support is fixed to the upper part of a portal frame located on one side of the slave belt pulley; and the sensor is arranged on the sensor fixing support in a matching way and is electrically connected with the machine tool electronic control system. The spindle running equipment and the spindle running detection mechanism thereof provided by the invention are simple and reasonable in structure design, and capable of quickly, accurately and stably detecting and responding to the power head spindle running state in real time.

[0002] At present, in the field of mechanical processing, the running state of the equipment spindle determines whether it can provide continuous and stable power for continuous processing of parts. When the spindle is abnormal, such as the spindle suddenly stops due to various unforeseen reasons, or the spindle speed is not If the setting interval is not detected in time and corresponding measures are not taken, it will cause great safety accidents and quality risks, such as knife collision, equipment spindle or fixture damage, parts scrapping and other losses

[0003] At present, the commonly used CNC lathes and machining centers all use encoders to detect the spindle speed. The cost is relatively high, the structure is complex, the installation and maintenance are difficult, and the working environment is demanding.

However, for the existing non-standard equipment, due to the tight cost budget and the harsh working environment of the equipment, if the encoder continues to be used to detect the running status of the equipment spindle, it will not only increase the production and processing costs, but also the encoder will be used in harsh environments. Real-time, fast, accurate, and stable detection and response cannot be carried out under the environment. Once a failure occurs during use, it will have a serious impact on the normal operation of the entire equipment, which will cause great safety accidents and product quality risks.
