我们在修理直角尺松动和百分表套筒松动的过程中,采用了环氧树脂粘结的办法,经过几个周期的检验,证明效果较好。方法是:对直角尺,首先取下尺座与尺苗,分别修好直线性和平行性;进而在尺苗的配合部位用片砂轮打磨出三条沟槽,以增加粘结面积;然后,在尺座与尺苗配合部位涂上粘结剂,并用平台与标准园柱校正角尺的垂直性。四个小时后,即成。对百分表套筒,则首先在配合部位用粗砂纸打毛,并涂上环氧树脂,表壳配合部位也涂上环氧树脂。然后,装上套筒,在装套筒的同时,把测杆也装上,并调正到最好位置,用小虎钳夹住。三个小时后,即成。环氧树脂的配方如下:
We repair the right angle foot loose and dial gauge sleeve loosening process, the use of epoxy bonding method, after several cycles of testing, the effect is better. The method is as follows: firstly, the scale base and the seedling seedlings are removed, and the linearity and parallelism are respectively repaired; further three grooves are polished with a sheet grinding wheel at the mating part of the seedling seedling to increase the bonding area; and then, Block with the seedlings with the site coated with adhesive, and with the standard square column and the correction of the vertical angle. Four hours later, Serve. On the dial gauge sleeve, the first with the co-sand with coarse sandpaper, and coated with epoxy resin, the case with the site also coated with epoxy resin. Then, install the sleeve, install the sleeve at the same time, the test rod is also loaded, and adjusted to the best position, with a small vise clamp. Three hours later, Serve. Epoxy resin formulations are as follows:
