Description
本發明係與進給系統之自動預壓裝置有關，尤指一種可自動因應不同剛性而調變預壓力量的進給系統之自動預壓裝。 The invention relates to an automatic preloading device of a feeding system, in particular to an automatic preloading of a feeding system capable of automatically adjusting a preload amount according to different rigidity.
如第5圖所示，為習用之進給系統，係一台座91上設有滑軌92，一載台93底部設滑塊94而可滑動地設於滑軌92上，台座91設有一傳動軸95，載台93底部與傳動軸95螺設，此傳動軸95的兩端分別架設於一軸座96，且傳動軸95於一端聯結一驅動馬達97，藉由該驅動馬達97的運轉而驅動該傳動軸95旋轉，藉此帶動該載台93於台座91上直線滑移。 As shown in FIG. 5, for the conventional feeding system, a pedestal 91 is provided with a slide rail 92, and a bottom of the loading table 93 is provided with a slider 94 slidably disposed on the slide rail 92, and the pedestal 91 is provided with a transmission. The shaft 95, the bottom of the stage 93 and the transmission shaft 95 are screwed. The two ends of the transmission shaft 95 are respectively mounted on a shaft seat 96, and the drive shaft 95 is coupled to a drive motor 97 at one end, and is driven by the operation of the drive motor 97. The drive shaft 95 rotates, thereby causing the stage 93 to slide linearly on the pedestal 91.
又如第6圖所示，各該軸座96內皆設有軸承961，當傳動軸95的端部組設於軸座96內時，會在軸承961的外側套設一預壓蓋951，並以迫緊件952於軸座96上對該預壓蓋951朝軸承961方向施壓迫緊，使軸座96內之軸承961得到預壓，藉而達到提高傳動軸95剛性之目的，而在載台93設置工件進行切削加工時，即便因切削加工而產生阻抗力，該傳動軸95仍可提供該載台93精準位移及定位。 然而，雖預壓蓋951被該迫緊件952施壓而對軸承9 61迫緊，惟當進給系統作動一段時間後，傳動軸95會因構件間的磨擦或環境溫度影響而使本身的溫度上昇，因而產生熱脹變形的情況，而傳動軸95變形時會導致其於軸向的長度伸長，預壓蓋951原先對軸承961的迫緊力量將隨著傳動軸95伸長而減弱，甚至消失，此時對軸承961便無法達到期望的預壓效果。 As shown in FIG. 6, each of the shaft seats 96 is provided with a bearing 961. When the end of the transmission shaft 95 is assembled in the shaft seat 96, a pre-pressing cover 951 is disposed on the outer side of the bearing 961. The pressing member 952 is pressed against the bearing 961 on the shaft seat 96 to press the bearing 961 in the direction of the bearing 961, so that the bearing 961 in the shaft seat 96 is pre-stressed, thereby achieving the purpose of improving the rigidity of the transmission shaft 95. When the stage 93 is provided with a workpiece for cutting, even if a resistance force is generated by the cutting process, the drive shaft 95 can provide accurate displacement and positioning of the stage 93. However, although the pre-pressure cap 951 is pressed by the pressing member 952, the bearing 9 is 61 is tight, but when the feed system is actuated for a period of time, the drive shaft 95 will increase its own temperature due to the friction between the components or the ambient temperature, thus causing thermal expansion and deformation, and the transmission shaft 95 will cause deformation. Its length in the axial direction is elongated, and the pressing force of the pre-pressing cover 951 to the bearing 961 will be weakened or even disappeared as the transmission shaft 95 is elongated, and the desired pre-compression effect cannot be achieved for the bearing 961 at this time.
有鑑於此，故如何解決上述問題，即為本發明所欲解決之首要課題，因此，本案發明人在經過不斷的苦思與試作後，才終於有本發明之產生。 In view of this, how to solve the above problem is the primary problem to be solved by the present invention. Therefore, the inventor of the present invention finally has the invention after continuous arduous thinking and trial work.

較佳地，該感測組包括有至少二溫度計、一加速規及一位移計，其中，該二溫度計分別設於該連接座及該軸承座上，而可分別量測該連接座與該軸承座之工作溫度，並相對產生一溫度值；而該加速規係設於該載台上，而可用以量測該載台於進行直線移動時之加速度值，並相對產生一加速度值；該位移計則設於該預壓裝置中，以即時量測該傳動軸之位移量，並相對產生一位移值。 Preferably, the sensing group includes at least two thermometers, an accelerometer and a displacement meter, wherein the two thermometers are respectively disposed on the connecting seat and the bearing seat, and the connecting seat and the bearing are respectively measured The operating temperature of the seat, and a relative temperature value is generated; and the acceleration gauge is disposed on the stage, and can be used to measure the acceleration value of the stage when the linear movement is performed, and relatively generate an acceleration value; the displacement The gauge is disposed in the preloading device to instantly measure the displacement of the drive shaft and relatively generate a displacement value.

At this time, the piston member in the cylinder body can be applied to the bearing in the bearing seat with a relatively large pre-pressure amount. To increase its preload value; conversely, when the logic judgment unit analyzes and judges that the rigidity of the drive shaft is too large, The pressure regulating valve is lowered to reduce the pressure value of the pressure medium input into the cylinder to reduce the preload value; and when the logic judging unit analyzes and judges that the rigidity of the transmission shaft is standard, the pressure regulating valve maintains the input The pressure value of the pressure medium in the cylinder.

For example, when the feed system is operated for a period of time, the drive shaft 14 causes its own temperature to rise due to the friction between the components or the influence of the ambient temperature, and thus the thermal expansion deformation occurs, at which time the logic determination unit 53 receives the data according to the reception. After analyzing the sensing signals (ie, the temperature value, the acceleration value, and the displacement value), the rigidity of the current transmission shaft 14 is automatically determined, and then the control signal corresponding to the rigid state of the current transmission shaft is outputted, and the pressure regulating valve 31 is The pressure value of the pressure medium input into the cylinder block 22 is adjusted in real time, and thereby the feed system has the effect of automatically adjusting the preload value according to the different rigidity of the transmission shaft 14.
接著請繼續參閱第4圖，為本發明之傳動軸剛性檢測流程，其係可在載台13上固定工件而準備進行切削加工之前，先以預設之載台13移動速度及行程距離，對該傳動軸14進行負載震盪測試，此時該微控制器模組51之邏輯判斷單元53即會依照該感測組41所量測到之數值(即感測訊號)，檢測該傳動軸14在負載時之剛性大小，並傳遞控制訊號予該調壓閥31，以進行預壓值之調整；也就是說，當該微控制器模組51之邏輯判斷單元53分析並判斷該傳動軸14之剛性不足時，即會令該調壓閥31增加輸入該缸體22內壓力介質之壓力值，此時缸體2 2內的活塞件23即可以相對較大的預壓力量施予軸承座15內的軸承151，以提升其預壓值；反之，當該邏輯判斷單元53分析並判斷該傳動軸14之剛性過大時，即會令該調壓閥31降低輸入該缸體22內壓力介質之壓力值，以降低其預壓值；而當該邏輯判斷單元53分析並判斷該傳動軸14之剛性為標準時，即會令該調壓閥31維持輸入該缸體22內壓力介質之壓力值。 Next, please refer to FIG. 4 again, which is a transmission shaft rigidity detecting process of the present invention, which is capable of moving the speed and the travel distance of the preset stage 13 before the workpiece is fixed on the stage 13 to be subjected to the cutting process. The drive shaft 14 performs a load oscillating test. At this time, the logic determining unit 53 of the microcontroller module 51 detects the drive shaft 14 according to the value measured by the sensing group 41 (ie, the sensing signal). The rigidity of the load is transmitted, and the control signal is transmitted to the pressure regulating valve 31 for adjustment of the preload value; that is, when the logic determining unit 53 of the microcontroller module 51 analyzes and judges the drive shaft 14 When the rigidity is insufficient, the pressure regulating valve 31 is increased in pressure value input to the pressure medium in the cylinder 22, and at this time, the cylinder 2 The piston member 23 in 2 can be applied to the bearing 151 in the bearing housing 15 with a relatively large pre-pressure amount to increase its preload value; otherwise, when the logic judging unit 53 analyzes and judges that the rigidity of the transmission shaft 14 is too large When the pressure regulating valve 31 is lowered, the pressure value of the pressure medium input into the cylinder 22 is lowered to lower the preload value; and when the logic determining unit 53 analyzes and determines that the rigidity of the transmission shaft 14 is the standard, The pressure regulating valve 31 is caused to maintain the pressure value of the pressure medium input into the cylinder block 22.
當然，本發明並不僅限用於進給系統在進行切削加工之前的事先檢測工作，其當然亦可在進給系統於加工過程中，透過該感測組41之各感測器的即時量測，而使該微控制器模組51可依據該感測組41所量測到之數值，檢測該傳動軸14在實際加工過程時之剛性大小，並即時傳遞控制訊號予該調壓閥31，使其在加工過程中同樣可進行預壓值之調整，並藉此即可自動因應不同剛性而調變預壓力量，使傳動軸14的剛性能隨該調變而維持穩定，故載台13移動的精準度及順暢度亦隨之穩定，令工件於切削加工時可具有極佳的尺寸精確度。 Of course, the present invention is not limited to the prior detection work of the feed system before the cutting process, and of course, the instantaneous measurement of each sensor through the sensing group 41 during the processing of the feed system. The microcontroller module 51 can detect the rigidity of the transmission shaft 14 during the actual processing according to the value measured by the sensing group 41, and immediately transmit a control signal to the pressure regulating valve 31. The pre-pressure value can also be adjusted during the processing, and the pre-pressure amount can be automatically adjusted according to different rigidity, so that the rigid performance of the transmission shaft 14 is maintained stable with the modulation, so the stage 13 The accuracy and smoothness of the movement are also stabilized, allowing the workpiece to have excellent dimensional accuracy during machining.
