Description

technical field [0001] The invention relates to a collection stand, in particular to a multi-channel numerical control machine tool energy consumption data collection stand. Background technique [0002] At present, the data acquisition and control experiment bench with the data acquisition module as the core is widely used in the research and application of the machine tool field. However, there are still some deficiencies in using the existing domestic and foreign data acquisition platforms to collect energy consumption of machine tools: [0003] (1) The functions of many data acquisition modules are relatively simple: the types of signals collected by many existing acquisition products are relatively single. When analyzing the energy consumption of machine tools, it is necessary to analyze the total energy consumption, total voltage, current, and spindle energy consumption of the machine tool , spindle voltage, spindle current, servo module energy consumption, servo modu...

Problems solved by technology

[0003] (1) The functions of many data acquisition modules are relatively simple: the types of signals collected by many existing acquisition products are relatively single. When analyzing the energy consumption of machine tools, it is necessary to analyze the total energy consumption, total voltage, current, and spindle energy consumption of the machine tool , spindle voltage, spindle current, servo module energy consumption, servo module voltage, servo module current, spindle speed, spindle torque and other multi-channel signals are collected. The existing equipment is mainly based on Japanese collection systems, which have a single collection function and Only one signal can be collected. When the physical quantity needs to be collected for a variety of complex on-site conditions, the collection system is difficult to meet the demand

[0004] (2) Low sampling frequency: For the existing acquisition system, its sampling frequency is low, which has serious limitations on the acquisition of machine tool data, and cannot completely express the physical quantity characteristics of the machine tool

[0005] (3) The construction and use of the experimental bench are cumbersome and inconvenient to operate: as far as the existing acquisition system is concerned, it is mainly for the acquisition of a certain signal, and its sensor wiring is difficult to meet the complex wiring of the machine tool
