Embodiment Construction

[0012] in figure 1 , figure 2 Among them, the present invention is provided with a lead screw 1, a screw frame nut seat 3 and a lead screw nut 2 are sleeved on the lead screw 1, a temperature sensor 4 is embedded on the lead screw nut 2, and the temperature sensor 4 is controlled by an AD converter and programmable logic The device is electrically connected. Temperature sensor 4 is a PT100 temperature sensor with a certain functional relationship between resistance and temperature. Through an AD converter, the analog signal sampled by the temperature sensor is converted into a digital signal and sent to the programmable logic controller. The CNC system PLC is programmed according to the A good program calculates the temperature value, compares whether the temperature is higher than the normal operating temperature of the machine tool screw, to judge whether the lubricating oil supply of the machine tool screw is normal, and displays alarms and prompts on the system display acc...

Abstract

The invention relates to a screw lubrication detecting device for a numerical control machine tool, belonging to the field of machine tools and comprising a lead screw, wherein the lead screw is sheathed with a screw frame nut seat and a lead screw nut; a temperature sensor is embedded on the lead screw nut; and the temperature sensor is electrically connected with a programmable logic controller through an A-D converter. The invention has the advantages that the structure is simple; the operation components of the machine tool can be prevented from influencing the production precision of workpieces because of frictional heating caused by poor lubrication condition; and the lead screw can be prevented from operating in a no lubricant state in a long time so as to influence the service life of the integral screw.

Description

Technical field [0001] The invention relates to the field of machine tools, in particular to a screw lubrication detection device for numerical control machine tools. Background technique [0002] As we all know, with the rapid development of machine tool technology and the continuous improvement of the overall level of the equipment manufacturing industry, the performance requirements of the ball screw, the core component of CNC machine tools, are also getting higher and higher. Due to poor lubrication conditions, friction and heat generation of machine tools will affect the machine tool. The position of the motion axis produces additional errors, which will directly affect the positioning accuracy of the machine tool, thereby affecting the machining accuracy of the workpiece. If the lead screw is operated for a long time without lubricating oil, it will also affect the lead screw itself, and the entire life of the lead screw will be greatly affected by long-term operation. In...
