Method and device for determining mechanical zero point and machine tool equipment

The invention discloses a method and device for determining a mechanical zero point and machine tool equipment. The method comprises the following steps of: detecting a current load rate when each coordinate axis of a target machine tool moves towards a first target direction; judging whether the current load rate of each coordinate axis reaches a load rate threshold or not; if the current load rate reaches the load rate threshold, stopping the coordinate axis from moving towards the first target direction, and performing returning to a preset position; and determining a final moving positionof the target machine tool as the mechanical zero point. According to the invention, the technical problems of low setting efficiency and low accuracy due to manual setting of the mechanical zero point in the prior art are solved. 本发明公开了一种机械零点的确定方法及装置、机床设备。其中，该方法包括：检测目标机床各坐标轴向第一目标方向移动时的电流负载率；判断每个坐标轴的电流负载率是否达到负载率阈值；若电流负载率达到负载率阈值，则停止坐标轴向第一目标方向移动，并返回预设位置；将目标机床的最终移动位置确定为机械零点。本发明解决了相关技术中通过人工设置机械零点，设置效率较低且准确度低的技术问题。
