一种顺序打开夹持装置
摘要：
本发明公开了一种顺序打开夹持装置，包括有夹紧支撑块、夹紧块，所述焊接支架放置在夹紧支撑块和夹紧块中间固定，所述夹紧块的中部设置有通孔，在所述通孔中设置有螺栓定位块，所述夹紧块和螺栓定位块为两个独立结构；通过将螺栓定位块和夹紧块设置成两个独立的机构，螺栓焊接定位完成后，先将螺栓定位块从螺栓上拉出（夹紧块保持不动），此时夹紧块仍将支架压贴在夹紧支撑块上，螺栓很容易从螺栓定位块中退出，本发明结构简单、操作方便、大大提高了焊接质量和效率。
摘要（英）：

The invention discloses a sequential opening and clamping device which comprises a clamping and supporting block and a clamping block. A welding support is arranged between the clamping and supporting block and the clamping block to be fixed. A through hole is formed in the middle portion of the clamping block. A bolt locating block is arranged in the through hole. The clamping block and the bolt locating block are of two independent structures. The bolt locating block and the clamping block are arranged to be two independent mechanisms, after bolt welding locating is completed, the bolt locating block is firstly pulled out of a bolt (the clamping block keeps still), the clamping block still enables the support to be pressed and attached to the clamping and supporting block at this moment, and the bolt can retreat from the bolt locating block easily. The sequential opening and clamping device is simple in structure and convenient to operate, and the welding quality and efficiency are greatly improved.
