在喷丸喷砂清理中,用国内普遍采用的喷丸(砂)装置,操作工本人不能在操纵喷枪的同时控制喷丸罐的开关,需由另一人配合操作,很不方便。为了防止环境污染,回收铁丸,保护工人健康,在清理铸件时:一般都采用密闭式清理室,由操作工人在室外用长喷枪进行清理。操作者需不断地改变工件和自身的位置和角度,来寻找和适应未清理的目标。这种改变是通过设备上的各种机构来完成的,都需要辅助时间。统计表明:虽然每个铺助时间并不太长,但却频繁发生,占全部操作时间的30～40％,
In the shot peening cleaning, shot peening (sand) device commonly used in China, the operator can not manipulate the gun at the same time control shot peening tank switch, the operation by another person, very inconvenient. In order to prevent environmental pollution, iron pills are collected to protect the health of workers. When cleaning castings, closed-type clean-up rooms are generally used and outdoor workers use long-length spray guns to clean them. Operators need to constantly change the position of the workpiece and its position and angle, to find and adapt to the unclear goals. This change is done through a variety of facilities on the device, all of which require supplemental time. Statistics show that: Although each paving time is not too long, but frequent occurrence, accounting for 30 to 40% of the total operating time,
