我所研制的码坯机组采用微机控制。该设备有一个重约2t 的夹盘,即大型机械手,每次夹取96块湿坯,按一定的节拍以200mm/s 的速度下降,向窑车上码放5层,完成一个大循环。夹盘在窑车上有五个停留位置(见图1),要求停位点不准确度不得大于±5mm。根据这一要求,按文献[1]、[2]的介绍,选用了如图2的平衡回路。根据文献[3]的介绍,选用Ⅺ-100B型平衡阀。此回路进行试运转时,发现停位信号发出后,夹盘仍继续下滑60～70mm,致使失去控制。
I developed the code blank unit using computer control. The device has a chuck about 2t weight, that is, a large robot grip each wet blank 96, at a certain beat at a speed of 200mm / s, to the car on the store on the 5th floor to complete a major cycle. Chuck in the car on the car there are five stops (see Figure 1), stop point inaccuracy requirements shall not be greater than ± 5mm. According to this requirement, according to the literature [1], [2] introduction, the selection of the balance circuit shown in Figure 2. According to the literature [3] introduction, choose Ⅺ-100B type balance valve. When this circuit is in trial operation, it is found that after the stop signal is issued, the chuck still continues to slide down 60-70mm, resulting in loss of control.
