我们是生产柴油机的专业厂,对铸件毛坯(如气缸盖、机体、齿轮箱)壁厚及型腔的检测较多。过去通常在平板上用高度游标卡尺配合划针盘检测,操作费工费时。现在我们在内、外卡钳的基础上改进自制了测量壁厚及型腔的卡钳,使用效果很好。图1是固定式测壁厚的卡钳,图2 We are a professional factory producing diesel engine, and we have more testing on wall thickness and cavity of casting blank (such as cylinder head, body, gear box). In the past, usually with a high degree of caliper vernier caliper with a flat plate inspection, the operating time and labor costs. Now we are in the internal and external calipers based on the improvement made of the wall thickness measurement and cavity calipers, the use of good results.
