The utility model is used for the quick switching of special tooling of metal working machine tools such as various machining centers, turning center and remodeling fast, eliminated the frock adjustment time of production line.Overcome the existing low defective of anchor clamps repetitive positioning accuracy, reach the raising working (machining) efficiency, the effect that reduces cost.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: vexed plug 1, chuck pedestal 2, plug screw 3, pallet bearing 4, attachment bolt 5, blind rivet 6, elasticity location-plate 7, piston 8, locking steel ball 9, stage clip 10, compression spring sleeve 11, press spring base 12.
The specific embodiment:
Next explanation at length below with reference to Figure of description a kind of machined of the utility model being done with the quick change repeated positioning device.
The quick change repeated positioning device is used in a kind of machined, its structure comprise offer centre bore and be installed on machine tool chief axis or work top on the chuck pedestal and through the pallet bearing of blind rivet location and installation in chuck pedestal top; Oil duct or air flue that said chuck pedestal set inside has oil cylinder or cylinder and is communicated with oil cylinder or cylinder; Said oil cylinder or air cylinder structure comprise the stage clip that piston and piston below connect; Said oil cylinder or cylinder inner cavity are communicated with chuck pedestal centre bore; On piston, offer spherical groove; On blind rivet, offer cannelure, said spherical groove and cannelure are provided with the locking steel ball through between oil cylinder or cylinder inner cavity and the intercommunicating pore that chuck pedestal centre bore is communicated with.Said pallet bearing offers locating hole and connecting hole, installs in the locating hole to be used for the alignment pin of positioning tool; The attachment bolt that is used for connecting fixing tool is installed in the connecting hole.Be provided with the elasticity location-plate between said chuck pedestal and the pallet bearing, said elasticity location-plate is installed on the pallet bearing, and the screw thread through blind rivet is tightened on the pallet bearing again.Said stage clip is installed in the compression spring sleeve and with the press spring base that is installed in the compression spring sleeve and tightens.The oral area of said oil duct or air flue is provided with vexed plug 1 or plug screw 3.Form a cross by 4 radially-arranged faceted pebble locating pieces on the said chuck pedestal.Form hollow cross recess by 4 radially-arranged elastic grooves on the said pallet bearing.
During work, just chuck pedestal 2 is fixedly mounted on machine tool chief axis or the work top earlier, and chuck pedestal 2 left side screwed holes are installed gas circuit or oil circuit, and chuck pedestal 2 right side screwed holes are installed gas circuit; When changing frock, the alignment pin on the frock is placed in the dowel hole of pallet bearing 4, frock is fixed on the pallet bearing 4 with attachment bolt 5; Then pallet bearing 4 sub-assemblies are put into through blind rivet 6 in the centre bore of chuck pedestal 2 and positioned; Carry out in the process in the location; The faceted pebble locating piece of chuck bearing 2 is embedded in pallet bearing 4 elastic grooves, forces elasticity location-plate 7 in place, makes the faceted pebble locating piece cross of chuck pedestal 2 and pallet bearing 4 hollow cross elastic grooves not have the gap driving fit; Thereby the location on the realization horizontal plane; Pallet bearing 4 sub-assemblies continue to move ahead and in, stage clip 10 clamping pistons 8 move upward the hole of extruding locking steel ball 9 from the piston 8, move to the centre bore of chuck pedestal 2 along the locking steel ball hole, when the external diameter of piston 8 withstands the external diameter of locking steel ball 9; Locking steel ball 9 just in time is positioned at the locking slot of blind rivet 6 and blind rivet 6 is lock onto the centre bore of chuck pedestal 2; Supporting plane on rest pad end face and the chuck pedestal is fitted at this moment, and the elastic centering plate is made micro-deformation, thereby realizes the location on the pallet bearing 4 sub-assembly vertical direction.Can carry out the clamping processing of part, when needs carry out renewal part clamping frock, open the gas circuit or the oil circuit in the left side of chuck pedestal 2; Compression piston 8 moves downwards; Pallet bearing 4 sub-assemblies are upwards operation under the elastic reaction of elasticity location-plate 7, and locking steel ball 9 is shifted under the effect of blind rivet 6 in the hole on the piston 8, and can unload pallet bearing 4 sub-assemblies and change this moment; Break off the left side gas circuit or the oil circuit of chuck pedestal 2, the action when installing above repeating is accomplished and is changed.If when the faying face of chuck pedestal 2 and pallet bearing 4 had foreign material such as iron filings, the gas circuit of opening chuck pedestal 2 right sides can blow off.
