Detailed description of the invention
In Fig. 1, Fig. 2, base plate 1 has the center stepped hole for installing deep groove ball bearing 13, base plate 1 is connected with rotating shaft 14 by deep groove ball bearing 13.Rotating shaft 14 upper end has fixing for base plate 1 nut 15 on the pedestal 11.Base 11 Shang You center counterbore, there is the small stair embedded in the counterbore of base 11 center rotating shaft 14 lower end.Base plate 1 is fixing on the pedestal 11 by rotating shaft 14, nut 15 and large pad 16, and base plate 1 and rotating shaft 14 are matched in clearance, can 14 rotate but can not throw off base 11 around the shaft.Base plate 1 is symmetrically installed with two cover Working piece positioning devices 8 and the rotatable pressing plate 5 of two covers, 3 fixed hinges 6 are also installed, two cover rotary pressure plates 5 are connected with trident connecting rod 9 by hinges 10, trident connecting rod 9 is connected with cylinder 12 by hinges 10, rotary pressure plate 5 is connected with base plate 1 by fixed hinge 6 with cylinder 12, rotary pressure plate 5 and cylinder 12 can rotate around fixed hinge 6 but can not depart from base plate 1, and fixed hinge 6 lower end needs to insert on base plate 1 fixing.
Base plate 1 is provided with 180 ° of arc guiding holes 4 centered by rotating shaft 14, prevents multiple rotations, and cylinder 12 air inlet pipeline takes up damage and loses function.Guiding depression bar 2 is loaded in arc guiding hole 4, arc guiding hole width is greater than guiding depression bar position diameter, centrosymmetric two locator card pin-and-holes (locating hole) are provided with in arc guiding hole end adjacent position, point-blank, each pin hole center and adjacent 180 ° of arc guiding hole 4 tail end distance of center circle are from equaling positioning clamping pin 3 center and guiding depression bar 2 centre distance for two locator card pin-and-hole centers and 180 ° of annular guide channels, 3 two tail end circle center line connectings.
Rotating shaft 14 and base 11 be interference fit, and lower end has in the center counterbore of a small stair embedding base, and rotating shaft 14 power upwards can not be departed from from base 11.Base 11 is being provided with a locating slot, placement positioning bayonet lock 3 in locating slot with arbitrary place locator card pin-and-hole concentric position on base plate 1, and guiding depression bar 2 bottom is loaded on the mounting groove that base 11 is opened, and positioning clamping pin 3 is fixed with guiding depression bar 2.Under free state, positioning clamping pin 3 top must not exceed plane on base, and guiding depression bar 2 top is higher than plane on base plate 1.There is a blind hole positioning clamping pin 3 bottom for placing spring 17.Positioning clamping pin 3 is matched in clearance with locator card pin-and-hole on base plate 1.
When workpiece 7 is at machining state, place second workpiece at offside, when workpiece 7 machines, start cylinder 12, by the motion of steam-cylinder piston, push away or draw trident connecting rod 9 to drive and rotate pressing plate 5, second workpiece is compressed while unclamping workpiece 7, guiding depression bar 2 position in pressing positioning clamping pin 3, positioning clamping pin 3 is deviate from from locator card pin-and-hole base plate 1, now hand-turning base plate, guiding depression bar 2 in positioning clamping pin 3 is relayed to 180 ° at arc guiding hole 4, after putting in place, positioning clamping pin 3 ejects under the elastic force effect of spring 17, insert second locator card pin-and-hole, locked base plate 1, now second workpiece arrives processing stations, can process.So move in circles, uninterrupted processing work can be completed continuously.
