Three, summary of the invention
Technical problem to be solved in the utility model provides a kind of precision height, can improve the rigid out-covered clamping device of vertical fine boring machine of processing work qualification rate.
For solving the problems of the technologies described above, the utility model rigid out-covered clamping device of vertical fine boring machine, comprise the anchor clamps tube that is provided with Connection Block, position, anchor clamps drum outer wall middle and lower part is provided with retainer ring, this retainer ring through O-ring seals and length less than the anchor clamps tube and be fixed with upper flange plate and the sleeve lining of lower flange cooperates, sleeve is provided with upper vent hole and following passage, and the inner face of described upper flange plate and lower flange all cooperates through the outer wall of O-ring seals with the anchor clamps tube; Described anchor clamps tube inwall is provided with centring ring and following centring ring, last centring ring is provided with the trim ring of fixation workpiece upper surface, the anchor clamps drum outer wall is fixed with support ring near the top, evenly be provided with three supports on the described support ring, each support all flexibly connects by axle and pressing plate, one end of described pressing plate is corresponding with the upper surface of trim ring, and the other end is corresponding with fore-set on being fixed on the sleeve upper flange plate.
Technique scheme is that last centring ring has been designed in the benchmark the inside and following centring ring is mated with the anchor clamps tube, and the cylindrical that utilizes the anchor clamps tube is designed to the piston rod of cylinder, the piston volume pressure can make three pressing plate work through fore-set by propelling sleeve, thereby pressure is pressed in workpiece pressing on the trim ring, as long as there is the compressed air source of 0.4～0.70Mpa just can operate.The utility model has solved and has occurred when causing boring when hole length is longer in the workpiece of big model that tapering is big, the depth of parallelism is poor, precision problems such as horn mouth phenomenon appear in two bores; fine finishining on this lathe can be guaranteed the effect that the jig form and position tolerance is unified for the workpiece counterpart, has satisfied the service precision requirement.
Adopt the utility model processing vapor cylinder sleeve, improved anchor clamps commutativity and installation accuracy, improved the quality of product.Compare the saving cost with existing anchor clamps, its manufacturing expense is about 2.5 ten thousand yuan.
