A numerical control multi shaft combination drilling machine is used for the processing of the support floor hole. The pneumatic modular fixture is installed on the middle base. The middle base is connected to the left base and the right base respectively. A left numerical control slide table and a right numerical control slide table are installed on the left base and the right base respectively. The variable speed box is installed on the NC slide table and the left numerical control is on the left. The base of the slide table and the right NC slide table is equipped with a silk base, and the screw pair is made up with a wire rod. The screw rod is connected by a servo motor, and it is fixed at the end of the left NC slide table and the right CNC sliding table. The screw leads the left CNC sliding table and the right CNC sliding table to move forward and back. The positive effect of the invention is that the device adopts a combined fixture, which only needs to replace the drill template, which can be processed for different types of products, and it is completed once by the bottom hole and the cap hole, and the new sliding platform is used to replace the traditional hydraulic sliding table with a linear guide, reducing the friction force and reducing the general machine tool. Power, moving faster and more smoothly.
【技术实现步骤摘要】
一种新型数控多轴组合钻床
本专利技术涉及汽车零部件制造的设备领域,特别涉及一种用于平衡桥大支架底板孔加工的数控多轴组合钻床。
技术介绍
商用车平衡桥大支架底板及上压盖孔大多还采用传统的工艺加工,即用一套夹具满足一套产品,同系列不同型号就需要配备各种夹具,并且底板孔与压盖孔需要分别做两套夹具和两台设备加工。底板孔数量多达17个,用传统摇臂钻床加工出的产品,因为不是一次成型,所以无法保证底板各孔的位置度,无法生产出合格产品,造成后序装配困难,并且加工过程是逐个孔加工,效率低下,这已严重制约了广大客户的生产,也无法满足产品的质量。基于此种状况,市场上也出现了液压多孔钻床,类似于传统的卧式对头钻床,而又在对头钻的动力头上加装了多根固定的钻杆轴,用液压油缸推动动力头上的多轴箱向前运动,实现钻孔加工。其缺点是:数字化程度低,采用PLC电器控制,行程需要靠有经验的工人师傅来调整,更换产品也是如此,对熟练操作人员依赖更大,对操作人员技术要求高。其次是此种设备是专用机型,更换产品则无法使用,另外采用液压控制,精度差,对支架压盖孔为盲孔来说,很难调整,调试困难,对环境污染大,对温度要求高;最后是钻头消耗大,磨损的钻头长短不一,造成了极大的浪费。基于此设备多项缺陷,已不能满足市场及客户的需求。
