为了在大型铸铁零件(如造纸机烘缸)上修磨补焊焊缝,我们设计了一台适用现场使用的手提式磨削装置,既可用来修磨弧面,也可修磨平面,介绍如下:该装置的结构见附图,磨削时的动力来源干手轮3,U形夹7(两个)将其固定在上支架10上.滚轮1(四个)安装在下支架11的下面.铰链9和铰链座12(两副)分别焊接在上支架和下支架上,将上支架和下支架联为一体.修磨时,将该装置放于烘缸上.使砂轮正对焊缝,四个滚轮要能够与烘缸外圆表面均匀接触.这时,即可
In order to grind and weld the weld on large cast iron parts (such as paper machine dryers), we have designed a hand-held grinding device for on-site use that can be used both for grinding the arc and for grinding the plane. As follows: The structure of the device is shown in the attached drawings, and the power source of the dry grinding wheel 3 and the clevis 7 (two) during grinding are fixed on the upper bracket 10. The rollers 1 (four) are installed under the lower bracket 11 The hinge 9 and the hinge seat 12 (two pairs) are respectively welded on the upper bracket and the lower bracket, and the upper bracket and the lower bracket are integrated together. When grinding, put the device on the drying cylinder, , Four rollers to be able to make uniform contact with the cylindrical surface of the dryer
