specific Embodiment 1

[0139] Specific embodiment 1: With the strengthening of environmental supervision, machine tool users are often faced with the situation of reducing product processing energy consumption. In order to obtain the energy consumption in product processing, it is necessary to accurately calculate the power of the machine tool. At this time, the calculation of the power of the machine tool spindle is one of them. A very important step, according to the above method of obtaining the power of the spindle system of the machine tool, such as figure 2 As shown, the method for the machine tool user to calculate the power of the spindle system and the correlation coefficient during the use of the machine tool includes the following steps:

[0140] Step 1-1: Determine the gear position of the machine tool;

[0141] Step 1-2: Determine the rated speed point of the spindle motor of the machine tool, and the rated speed point is the dividing point between the constant torque area and the cons...

[0169] Specific embodiment three: In some simulation calculations or design calculations, it is often necessary to directly calculate the total energy consumption of the spindle system. According to the above-mentioned method for obtaining the power of the spindle system of a machine tool, as Figure 4 As shown, the method for obtaining the power of the machine tool spindle system includes the following steps:

[0170] Step 3-1: Determine the operating range of the spindle motor, if it is running in the constant torque area, go to step 3-2; if it is running in the constant power area, go to step 3-9;

[0171] Step 3-2: Determine whether to adopt the power calculation model of the machine tool spindle system in the constant torque zone before simplification, if not simplified, go to step 3-3; if simplified, go to step 3-5;

[0172] Whether simplification is required depends on the accuracy requirements of the calculation results. If the accuracy requirements are relatively low,...

Abstract

The invention, which relates to the fields of machine manufacturing, motor, and driving, provides a method for obtaining a power of a main shaft system of a machine tool. With the method, problems that prediction of the energy consumption of the machine tool at the design stage can not be realized and requirements of the machine tool energy-saving design and the energy-saving modification can not be met according to the existing method for obtaining a power of a main shaft system can be solved. The method comprises: step one, a main shaft system is divided into a main shaft motor drive system, a main shaft mechanical drive system, and a tail end execution mechanism; step two, a power flow of the main shaft system of the machine tool is analyzed to obtain a main shaft system power PSR: PSR=Psd-loss + Psm-loss + Psm-out (formula I), wherein the Psd-loss expresses the power loss of the main shaft motor drive system, the Psm-loss expresses the power loss of the main shaft motor, the Psm-out expresses the output power of the main shaft motor, and the Psm-out is equal to the power Pspin-mec of the main shaft mechanical transmission system. According to the invention, the method is used for obtaining a specific structural parameter of a machine tool.

Description

technical field [0001] The invention relates to the fields of mechanical manufacturing, motors and drives, and in particular to a method for calculating the power of the main shaft of a machine tool. Background technique [0002] From the 1992 United Nations Framework Convention on Climate Change to the 2005 Kyoto Protocol, carbon emissions, carbon tariffs, and carbon trading are gradually becoming new trade barriers in international trade. The European Union's "20 / 20 / 20by2020" principle and Germany's "Energy Perspective 2050" both proposed clear targets for energy conservation and emission reduction; High punitive tariffs are imposed on emission-intensive products; the ISO14955 standard is specially designated for the environmental impact assessment of machine tools, focusing on the energy consumption of machine tools, making the energy consumption index of machine tools a market entry threshold for machine tools. Two parts have been released so far, and the rest It is bei...
