One slide block 15, for a movable clamp structure 30 against slippage, but and slide block 15 be provided with the compression spring 41 that a pushing tow drive block 22 resets to top offset with drive block 22 appropriate locations.
One drives structure 20, comprise that (this pneumatic cylinder 21 only is an embodiment of the present utility model to a pneumatic cylinder 21, also can use oil hydraulic cylinder) and a drive block 22, wherein drive block 22 is to be an oblique cone shape, and be arranged in the receiving part 11 of perforating press clamping body 10, this drive block 22 is subjected to a pneumatic cylinder 21 to drive control.
One pneumatic cylinder 21, be to be installed in perforating press clamping body 10 tops, wherein be provided with an atmospheric pressure pole 23 in the pneumatic cylinder 21, this atmospheric pressure pole 23 passes the hole portion 12 of receiving part 11, and be a continuous action relation with drive block 22, like this, when pneumatic cylinder 21 actions, promptly can drive atmospheric pressure pole 23 displacements, and then make drive block 22 upper and lower displacements.
One movable clamp structure 30, be against slippage on the slide block 15 of the lower end of perforating press clamping body 10, comprise: several spacings are separated the movable block 31 and a clamping part 33 of shape, movable block 31 1 ends wherein, be to form and the corresponding oblique cone of drive block 22 portion 32, oblique cone portion 32 is a sliding relationship with drive block 22.In addition, symmetry shape movable block 31 appropriate locations are provided with a perforation 35, this perforation 35 is to supply the pushing portion 13 of perforating press clamping body 10 to penetrate to protrude out, and pushing portion 13 and 35 formation of perforation can be for the required displacement spaces of movable block 31, so, and when preventing the inside lateral displacement of movable block 31, replace pushing portion 13.
One clamping part 33 is to utilize the screw tightening spiral shell solid in movable block 31 outsides, makes movable block 31 and clamping part 33 be one and sets firmly continuous action relation, and this clamping part 33 is provided with a recess 34, and this recess 34 is for wheel rim one end phase fit contact.
One compression spring 41, one end are to be installed in pushing portion 13 terminal appropriate locations, and the other end then is installed in movable block 31 lower end appropriate locations, by the elastic-restoring force of compression spring 41, movable block 31 is resetted fast.
From the above mentioned, when pneumatic cylinder 21 actions, make atmospheric pressure pole 23 produce action, and interlock and atmospheric pressure pole 23 are the drive block 22 of continuous action relation to bottom offset, and be the symmetrical movable block 31 of a sliding relationship with drive block 22, also can generate one and condense in laterally and move, and make clamping part 33 lateral displacements that are installed in movable block 31 outsides, and reach clamping wheel rim effect.At last, cooperate a punching pin device 50 again, can reach the identical effect of above-mentioned most preferred embodiment;
Otherwise, when desiring that spoke hole is dashed and establish the wheel rim of finishing to get loose, also be sharp pneumatic cylinder 21, make upwards action of atmospheric pressure pole 23, and interlock drive block 22 to top offset, spiral shell is solid at movable block 31 simultaneously, and compression spring 41 elastic resets on the pushing portion 13, and then drive movable block 31 lateral displacements reset.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
