Description
本發明係關於一種無線量測補償裝置,尤指一種用以量測多軸工具機作動之無線量測補償裝置者。 The invention relates to a wireless measurement and compensation device, in particular to a wireless measurement and compensation device for measuring the operation of a multi-axis machine tool.
按,近年來由於多軸加工技術的提升,目前多軸工具機已經逐漸受到工業界的重視與使用,目前市面上僅有非接觸式儀器(Non-bar或R-test)及接觸式探頭等量測裝置,可檢測多軸工具機之性能,在使用上既有接觸式儀器(Non-bar)可檢測多軸工具機的動/靜態性能,但需要離線檢測,而既有接觸式探頭僅可檢測多軸工具機之靜態性能,但可進行線上檢測;然而,既有的量測裝置雖能量測出多軸工具機的誤差並予以補償改善,進而提高多軸工具機的加工精度,然而,既有量測裝置會受到量測裝置本身傳輸線的纏繞而產生干涉的現象,導致多軸工具機於量測時,則無法透過該多軸工具機進行加工,相對會增加多軸工具機的非生產時間,甚至影響整條生產線的工作效率而產生延宕的情形;再者,既有量測裝置並未與一如電腦的運算處理單元與多軸工具機的控制器相連接,因此,當既有量測裝置量測得到誤差值時,無法自動地輸入該多軸工具機控制器內進行誤差補償,而必須經由人工判讀誤差值並手動輸入誤差值的方式進行補償的動作,在操作上相當不方便且耗時,相對會提高量測所需的成本與時間,誠有加以改進之處。 According to the improvement of multi-axis machining technology in recent years, multi-axis machine tools have been gradually valued and used by the industry. Currently, there are only non-contact instruments (Non-bar or R-test) and contact probes on the market. The measuring device can detect the performance of the multi-axis machine tool. In use, the contact instrument (Non-bar) can detect the dynamic/static performance of the multi-axis machine tool, but it needs offline detection, and only the contact probe only It can detect the static performance of the multi-axis machine tool, but it can be tested on-line; however, the existing measuring device can measure the error of the multi-axis machine tool and compensate and improve it, thus improving the machining accuracy of the multi-axis machine tool. The measurement device may be interfered by the winding of the transmission line of the measuring device itself, so that when the multi-axis tool machine is measured, the multi-axis machine tool cannot be processed, and the multi-axis machine tool is relatively increased. Non-production time, even affecting the efficiency of the entire production line, resulting in delays; in addition, the existing measuring device is not connected with the controller of the computer and the controller of the multi-axis machine tool Connection, therefore, when the existing measuring device measures the error value, the error compensation cannot be automatically input into the multi-axis machine tool controller, but must be compensated by manually interpreting the error value and manually inputting the error value. Actions, which are quite inconvenient and time consuming to operate, will increase the cost and time required for measurement, and there are improvements.
