3) The production of engine changes along with the season changes greatly, and it is also so that the intake is taken over, sometimes a batch is thousands of, sometimes a batch is only dozens of, so considered in vertical machining center, drilling center and the commonality on the rocking arm bores, designed interchangeable drill bushing 3, also added bush 18 to prevent pulling out the drill bushing many times and causing the wearing and tearing of roof 11.
When the batch size is large, the fixture can be used on a multi-head drill to play the advantages of rapid multi-hole simultaneous processing; when the batch is small, the compression screw 17 is loosened, the replaceable drill bushing 3 can be drawn out, and the clamp can be used on a vertical machining drill, a numerical control drill or a rocker drill at the moment so as to relieve the insufficient pressure of equipment.
4) The drill clamp disclosed by the utility model well solves the two problems of large size variation of workpieces and troublesome clamp adjustment, and can complete the adjustment of the clamp within half an hour according to the variation of each batch of blanks.
5) The drill clamp also considers the selection of equipment, and can be used on a multi-head drill, a vertical machining center, a numerical control drill and a rocker arm drilling machine.
