本發明係屬曲柄軸加工的技術領域，尤指其技術上提供一車床多偏心夾具，透過徑向偏心量及環向角度偏移量之調整結構，使得僅需具備XZ雙軸向加工能量之車床，即可進行多重偏心加工。The invention belongs to the technical field of crankshaft machining, in particular to technically providing a lathe multi-eccentric clamp, which has an adjustment structure of radial eccentricity and circumferential angular offset, so that only XZ biaxial machining energy is needed. On the lathe, multiple eccentric machining is possible.
目前，市面上曲柄軸普遍使用CNC臥式銑床或CNC車床進行加工，惟，直接使用CNC臥式銑床做加工具有下述缺點：(1).工時過於冗長。(2).CAM程式過長撰寫耗時。(3).銑削偏心軸難以得到真圓。(4).製作多重偏心需經常更換夾具，定位不易。(5).針對每種偏心軸皆需製作特殊夾具做夾持，夾具需求種類繁多大幅增加成本支出。直接使用CNC車床做加工具有下述缺點：(1).須撰寫巨集指令，專業需求度高。(2).車床須具備XYZC軸向加工能量，設備成本偏高。(3).可用速差做車削，但無法得到真圓。(4).製作多重偏心需經常更換夾具，定位不易。(5).針對每種偏心軸皆需製作特殊夾具做夾持，夾具需求種類繁多大幅增加成本支出。另習知曲柄軸加工夾具如第7A及7B圖所示，其包含二偏心盤70，各該偏心盤70一端分別設置有一傳動軸71，各該傳動軸71旁側分別貫設一偏心孔72，一工作物80二端分別套設於各該偏心孔72，二固定螺絲73分別將該工作物80二端固設於各該偏心盤70，各該傳動軸71分別夾設於加工機(圖未示)，一刀具90對該工作物80之一第一曲柄軸81進行加工，此時各該傳動軸71及該第一曲柄軸81呈同軸心設置，上述夾具僅適用於第一曲柄軸81加工，無法應用於第二曲柄軸82等不同偏心量曲柄軸之加工，亦即針對多重偏心工作物必需準備各式不同的夾具，造成生產成本的增加，實有加以改良的必要。At present, the crankshafts on the market are generally processed by CNC horizontal milling machines or CNC lathes. However, the direct use of CNC horizontal milling machines for processing has the following disadvantages: (1). Working hours are too long. (2). The CAM program is too long to write and take time. (3) It is difficult to obtain a true circle for milling the eccentric shaft. (4). It is necessary to change the fixture frequently to make multiple eccentricities, and the positioning is not easy. (5). For each type of eccentric shaft, special fixtures need to be made for clamping, and the variety of fixture requirements greatly increases the cost. Direct use of CNC lathes for processing has the following disadvantages: (1). It is necessary to write a macro instruction, and the professional demand is high. (2). The lathe must have XYZC axial processing energy, and the equipment cost is high. (3). The speed difference can be used for turning, but the real circle cannot be obtained. (4). It is necessary to change the fixture frequently to make multiple eccentricities, and the positioning is not easy. (5). For each type of eccentric shaft, special fixtures need to be made for clamping, and the variety of fixture requirements greatly increases the cost. As shown in FIGS. 7A and 7B, the conventional crankshaft machining jig includes two eccentric discs 70. One end of each of the eccentric discs 70 is respectively provided with a transmission shaft 71, and an eccentric hole 72 is respectively disposed on the side of each of the transmission shafts 71. The two ends of a working object 80 are respectively sleeved on the eccentric holes 72, and the two fixing screws 73 respectively fix the two ends of the working object 80 to the eccentric disks 70, and the transmission shafts 71 are respectively disposed on the processing machine ( In the figure, a cutter 90 processes the first crankshaft 81 of one of the workpieces 80. At this time, each of the transmission shafts 71 and the first crankshaft 81 are disposed concentrically, and the clamp is only suitable for the first crank. The machining of the shaft 81 cannot be applied to the machining of different eccentric crankshafts such as the second crankshaft 82, that is, it is necessary to prepare various clamps for multiple eccentric work, which increases the production cost and is necessary for improvement.
