Aspects of the disclosure relate to grabbing, holding and releasing an object (30) including a pull stud (200). For instance, a grabbing mechanism (100) may include a piston chamber (134) having a piston (136) configured to move within the piston chamber when the piston chamber is pressurized. The mechanism may also include a collet (170) attached to the piston such that the collet and piston movetogether when the piston moves. The collet may include a groove (174). The mechanism may also include ball cage (160) including a plurality of balls (164, 165) arranged at least partially within respective ball chambers (166, 167) of the ball cage. The ball cage may be arranged at least partially within the collet such that movement of the piston and collet causes the groove to align with the respective ball chambers. The plurality of balls may be configured to move into and out of the groove and to lock the pull stud within the mechanism.

    本公开的方面涉及抓取、保持和释放包括拉杆(200)的物体(30)。例如,抓取机构(100)可以包括具有活塞(136)的活塞室(134),该活塞配置为当活塞室被加压时在活塞室内运动。该机构还可以包括筒夹(170),该筒夹附接到活塞,使得当活塞运动时,筒夹和活塞一起运动。筒夹可以包括凹槽(174)。该机构还可以包括滚珠轴承罩(160),该滚珠轴承罩包括至少部分地布置在滚珠轴承罩的相应滚珠室(166、167)内的多个滚珠(164、165)。滚珠轴承罩可以至少部分地布置在筒夹内,使得活塞和筒夹的运动导致凹槽与相应滚珠室对准。所述多个滚珠可以配置为运动进入和运动离开凹槽并将拉杆锁定在该机构内。
