在GB355—64型、TGT—300型、TGT—500型台秤上,台板下面不使用方架和弹子,而是在台板四角重点位置固有装刀垫用的四个支架。支架在使用中有时会折断,一般的修理方法,是用气焊或电焊,焊上新的支架。但这样焊上去的支架,往往容易变形,造成比较大的示值变动性。我们采用另外一种修理方法,效果比较好。在原来固定支架的铸桩上,用钢锯居中锯出两条深20毫米的平行锯缝,它们之间的距离与要安装的新支架的宽度相等。然后用錾子铣成一个凹槽,再用整形锉刀把槽壁锉平,一般这个凹槽的宽度为4毫
On the GB355-64, TGT-300 and TGT-500 scales, the square frame and the marbles are not used under the platen. Instead, the four brackets are used to fix the cutter pad at the four corners of the platen. Bracket in use sometimes broken, the general repair method is to use gas welding or welding, welding a new bracket. However, the brackets welded up in this way tend to be easily deformed, resulting in a relatively large change of indication. We use another method of repair, the effect is better. On the original cast-in pile of the stationary support, two 20 mm deep, parallel kerfs are sawed centrally with a hacksaw, with a distance equal to the width of the new stand to be installed. And then use a razor milling into a groove, and then plastic file rasp wall file, the general width of this groove 4 milliliters
