The cylinder drives the reciprocating displacement speed of the table, which in turn can effectively save energy and improve the service life of the hydraulic drive system of the grinding table.
請參閱第1圖所示，一般磨床係於機台上設有可作水平方向滑移之工作台，該工作台連結於液壓缸10，並以一液壓驅動系統20驅動該液壓缸10之活塞桿帶動工作台作水平方向的往復位移，該液壓驅動系統20係根據驅動液壓缸10所需承受的最大負載(如工作台往復位移之最高速度)，於儲油槽21連接一液壓泵22，並以具有足夠輸出功率之馬達23驅動液壓泵22輸出定量的油液，另於該液壓泵22之輸出端連接一流量控制器24，並於該流量控制器24與液壓缸10間連接設有具換向閥25之換向控制裝置，而於進行研磨作業時，即可由馬達23驅動液壓泵22輸出油液，並經由換向控制裝置之換向閥25輸出，以驅動液壓缸22之活塞桿帶動工作台作高速度的往復位移，另於進行工件校準作業時，或於研磨進給量不同時，或於研磨據不同材質之工件時，則利用該流量控制器24進行調整控制油液之輸出流量，進而可調整液壓缸10之活塞桿帶動工作台以較慢的速度往復位移；惟，該液壓驅動系統20於使用上仍有如下之缺弊：Referring to FIG. 1 , the general grinder is provided with a table for horizontal sliding on the machine table. The work table is coupled to the hydraulic cylinder 10 and drives the piston of the hydraulic cylinder 10 by a hydraulic drive system 20 . The rod drives the table to perform a horizontal reciprocating displacement. The hydraulic drive system 20 is connected to a hydraulic pump 22 in the oil storage tank 21 according to the maximum load required to drive the hydraulic cylinder 10 (such as the maximum speed of the reciprocating displacement of the table). The motor 23 with sufficient output power drives the hydraulic pump 22 to output a certain amount of oil, and a flow controller 24 is connected to the output end of the hydraulic pump 22, and the flow controller 24 is connected with the hydraulic cylinder 10 The reversing control device of the reversing valve 25, when the grinding operation is performed, the hydraulic pump 22 is driven by the motor 23 to output the oil, and is output via the reversing valve 25 of the reversing control device to drive the piston rod of the hydraulic cylinder 22. Driving the table for high-speed reciprocating displacement, and when performing workpiece calibration work, or when grinding feed amount is different, or when grinding workpieces of different materials, the flow controller 24 is used for adjustment control Output flow of the liquid, and thus adjust the cylinder rod 10 of the drive stage reciprocally displaced at a slower rate; However, the hydraulic drive system 20 is still in use as the mischief of:
1.該液壓驅動系統20係利用該流量控制器24進行調整控制油液之輸出流量，以調整工作台的往復位移速度，然而，當調整工作台以較慢的速度往復位移時，雖驅動液壓缸20所需的油液流量較少，該馬達 22卻仍以最大的輸出功率驅動液壓泵23輸出定量的油液，因此，該液壓泵23所輸出油液將有部份回流至儲油槽21，而於馬達22產生許多無效動運轉，進而造成能源上的浪費。1. The hydraulic drive system 20 uses the flow controller 24 to adjust and control the output flow of the oil to adjust the reciprocating displacement speed of the table. However, when the adjustment table reciprocates at a slower speed, the hydraulic pressure is driven. The cylinder 20 requires less oil flow, the motor 22, the hydraulic pump 23 is still driven to output a certain amount of oil at the maximum output power. Therefore, the oil outputted by the hydraulic pump 23 is partially returned to the oil storage tank 21, and the motor 22 generates a lot of ineffective operation, thereby causing Waste of energy.
2.該液壓驅動系統20之馬達22啟動時，該馬達22即以最大的輸出功率驅動液壓泵23輸出定量的油液，且當調整工作台以較慢的速度往復位移時，該液壓泵23所輸出的油液將有部份回流至儲油槽21，其不僅使得油液無法順暢流通，且易導致油液溫度過高，進而影響液壓驅動系統20之使用壽命。2. When the motor 22 of the hydraulic drive system 20 is started, the motor 22 drives the hydraulic pump 23 to output a certain amount of oil at the maximum output power, and when the adjustment table reciprocates at a slower speed, the hydraulic pump 23 The outputted oil will be partially returned to the oil storage tank 21, which not only makes the oil flow unsmooth, but also causes the oil temperature to be too high, thereby affecting the service life of the hydraulic drive system 20.

請參閱第4、5圖所示，本創作於控制工作台32以較低的速度往復位移時(如校準作業)，首先將工件50架置固定於工作台32上，而可控制該供壓裝置43之第一馬達434驅動第一液壓泵431輸出儲油槽42內之油液，並經由換向控制裝置44之換向閥441切換油路方向，以驅動該液壓缸41帶動工作台32往復位移，另於校準作業之過程中，又可以該供壓裝置43之流量控制器437，以調整由該供壓裝置43之第一液壓泵431輸出適量之油液，而驅動該液壓缸41帶動工作台32作較低的速度往復位移， 以便進行校準作業；藉此，本創作係根據驅動液壓缸41所需承受的最大負載(如工作台32往復位移之最高速度)，而於該儲油槽42連通配置以第一馬達434驅動之第一液壓泵431、以第二馬達435驅動之第二液壓泵432及以第三馬達436驅動之第三液壓泵433，而以該供壓裝置43之第一液壓泵431、第二液壓泵432及第三液壓泵433分配輸出液壓缸41所需承受之最大負載，因此，於進行校準作業，由於僅需控制該供壓裝置43之第一馬達434驅動第一液壓泵431，以輸出適量之油液，其不僅可避免於供壓裝置43之第一、二、三馬達434、435、436產生無效動運轉，並使得油液順暢流通，以防止油液溫度過高，進而達到有效節能提昇使用壽命之實用效益。Referring to Figures 4 and 5, when the control table 32 is reciprocally displaced at a lower speed (e.g., calibration operation), the workpiece 50 is first mounted on the table 32, and the supply pressure can be controlled.

The three hydraulic pumps 431, 432, and 433 output oil, and switch the oil passage direction via the switching valve 441 of the reversing control device 44 to drive the hydraulic cylinder 41 to drive the table to perform high-speed reciprocating displacement to meet the grinding operation demand.
藉此，本創作係利用該供壓裝置之各液壓泵分配輸出液壓缸所需承受之最大負載，即可根據不同作業需求，而選擇控制各馬達分別驅動各液壓泵輸出油液，即可調整液壓缸帶動工作台的往復位移速度，以避免於供壓裝置之各馬達產生無效動運轉，並使得油液順暢流通，以防止油液溫度過高，進而進而達到有效節能及使用壽命之實用效益。Therefore, the creation system uses the hydraulic pumps of the pressure supply device to distribute the maximum load that the output hydraulic cylinder needs to bear, and can select and control each motor to drive each hydraulic pump output oil according to different operation requirements, thereby adjusting The hydraulic cylinder drives the reciprocating displacement speed of the table to avoid ineffective operation of the motors of the pressure supply device and to make the oil flow smoothly to prevent the oil temperature from being too high, thereby achieving the practical benefits of effective energy saving and service life. .
