Fig. 1 is front view of the present invention;
Fig. 2 is side view of the present invention;
Fig. 3 is the structural representation of base plate of the present invention;
Fig. 4 is the side view of base plate of the present invention.
In figure, 1-milling machine table, 2-tee-slot, the right thimble seat of 3-, 4-claw thimble, 5-base plate, 6-through hole, 7-T shape bolt, 8-locating piece, the left thimble seat of 9-, the 10-self-pressing type thimble that stretches, 11-hand-operated wheel.
The specific embodiment
Referring to Fig. 2-4, the quick positioning and clamping device of keyway of the present invention, there is milling machine table 1, the top of milling machine table, middle part, three tee-slots 2 are arranged at bottom respectively lateral arrangement, the right side of milling machine table 1 is provided with right thimble seat 3 by the tee-slot 2 on tommyhead bolt 7 and milling machine table, right thimble seat 3 is provided with claw thimble 4, the top of one base plate 5, middle part, bottom has some through holes 6, through hole 6 is corresponding with three tee-slots 2 on milling machine table, pass tee-slot on bottom hole and milling machine table base plate be arranged on the left side of milling machine table by tommyhead bolt, the tommyhead bolt at base plate 5 middle parts is provided with locating piece 8, base plate 5 is provided with left thimble seat 9, left thimble seat 9 is provided with the flexible thimble 10 of self-pressing type, the tail end of the flexible thimble 10 of self-pressing type is provided with hand-operated wheel 11.Using method: first the tommyhead bolt on right thimble seat is close in tee-slot side and fixing right thimble seat, then the locating piece on the base plate under left thimble seat is close to tee-slot side fastening, lock again the upper and lower two ends of base plate tommyhead bolt, guarantee like this symmetry and the depth of parallelism of the thimble at two ends, finally change hands workpiece that wheel will process and be placed between two thimbles of left and right and hold out against and can process keyway, after completion of processing, as long as rotate handwheel, unclamp workpiece, be loaded on another workpiece.
