The specific embodiment
Referring to Fig. 1 and Fig. 2, cam-type quick-speed jigs of the present utility model comprises: anchor clamps connecting plate 1, little wedge 2, big wedge 4 and main presser device 16.
Referring to Fig. 1 and Fig. 4.Anchor clamps connecting plate 1 is a rectangular slab, and there is the square groove 17 of perforation the upper end, below square groove, is equipped with mounting hole 18 with the level near the plate interposition.Customization soket head cap screw 3 is housed in the mounting hole 18, is used for and the fixedlying connected of little wedge 2.One circular concave surface 19 is arranged in the nearly center of rectangular slab, in to inlay through heat treated cylindrical steel part be mold insert 20, this mold insert 20 is bumped into that back upper surface and plate polish in the plate.The screwed hole 21 that symmetrical distribution is arranged in mold insert 20 both sides.In the bottom of plate five flat spring eyes 22 of bottom ream are arranged, place compression spring 8 in the hole.One group of through hole 23 is arranged above spring eye, is the installing hole of screw 6, and screw 6 passes through hole 23 the described main pressing plate 9 in big wedge 4 and back is connected.
Referring to Fig. 1 and Fig. 5, main presser device 16 is made up of main pressing plate 9, threaded pin 10, decenter clutch 11, woodruff key 14 etc.Main pressing plate 9 is rectangular slabs, and there is mounting hole 27 centre on top, and the right of mounting hole 27 links to each other with square groove 28.Be formed with screw thread pin-and-hole 29 on the top of mounting hole 28, there is screw thread the upper end of screw thread pin-and-hole 29.In mounting hole 27 and square groove 28 decenter clutch 11 is installed, spanner 11 usefulness threaded pins 10 are connected with main pressing plate 9.The lower end of main pressing plate 9 has one to extend inclined-plane 39.Inclined-plane 39 gradients (with respect to vertical plane) are spent to 20 degree scopes 15, have rectangular boss 30 to link up with in the inboard of main pressing plate 9, are used to tangle patrix.The arc groove 31 of one smooth perforation is arranged above boss 30, woodruff key 14 is housed in the groove 31,,, woodruff key 14 is connected on the main pressing plate 9, and makes woodruff key 14 in groove 31, can carry out a spot of flexibly rotation through screw hole 32 with screw 13.Be drilled with two screw holes 33 that are connected with big wedge 4 in the centre of main pressing plate 9, be processed into sphere at the bottom of the hole, main pressing plate 9 can be swung around screw 6.Screw 6 customizes, and is used to connect main pressing plate 9 and big wedge 4, and screw 6 is arc surfaces that R is arranged with the contact surface in main bridge screw hole 33, in the suitable minification in collar position, main pressing plate 9 can be swung around screw 6.
Referring to Fig. 1 and Fig. 6.Decenter clutch 11 is drilled with centre bore 34 for head has the rectangle or the circular rod member of circular arc boss at head, and central hole size cooperates with the threaded pin diameter for basic hole system H8 level and cooperates.There is eccentric throw 35 in the Center-to-Center hole of circular arc boss.Spanner 11 heads are through heat treated, and the middle part of decenter clutch 11 and rear end are adopted to soak and moulded technology and be enclosed with the anti-skidding plastic cover, and spanner can be located when a certain angle position.When decenter clutch 11 usefulness threaded pins 10 are connected with main pressing plate 9, be lined with plain washer 12 at the upper and lower faces of spanner.
After main pressing plate 9 and big wedge 4 usefulness customization soket head cap screw 6 are connected, need to adjust customize soket head cap screw 6 be screwed into depth dimensions to rational position, make main pressing plate 9 can fasten patrix 15 and do not have slippage and become flexible phenomenon.Be screwed into holding screw 7 without a head in the screw hole 26 of big wedge 4 this moment, with screw 6 fastening location.
After the anchor clamps assembling, left and right push-and-pull decenter clutch 11, the circular arc boss of the off-centre of decenter clutch 11 is resisted against on the mold insert 20, because of eccentric throw 35 is arranged, make main pressing plate 9 upper ends along with the rotation of spanner 11 produces different displacement with respect to connecting plate 1, the line that main pressing plate 9 can be shown a plurality of screws 6 this moment greatly is that center line carries out deflection, and main simultaneously pressing plate 9 forms different opening size A in the lower end of plate under the effect of compression spring 8.When decenter clutch 11 was drawn out to 90 degree positions, the displacement minimum of the upper end of main pressing plate 9 was pushed open main pressing plate 9 lower ends by compression spring 8.The opening size A of lower end is maximum, this moment, patrix 16 can directly insert in the anchor clamps master pressing plate 9, can inwardly shift decenter clutch 11 onto 45 then spends to 30 degree scopes, make boss 30 tangle patrix 15, can adjust patrix 16 to suitable fixed position, at last decenter clutch 11 is inwardly shifted onto the end during zero degree, then can lock fixedly patrix fully.Need to regulate the length dimension of patrix, then can unclamp decenter clutch 11, will not unload by patrix, directly insert the little diffusing cutter patrix that needs increase in position, can carry out quick-clamping.
The beneficial effects of the utility model are as follows:
1, on clamping, in the mold process, only need push away, draw decenter clutch, get final product the clamping patrix, save the clamping time.
2, on clamping in the mold process, decenter clutch is in 90 degree positions, and 45 degree can form different opening size A in main pressing plate lower end, convenient dismounting patrix to 30 degree range position. When needs are adjusted the patrix length dimension, only need directly to insert the diffusing cutter patrix of small size, more convenient.
3, these anchor clamps have been reduced the number of the redundancy function part in the situation that satisfies client's instructions for use, and its structure is compact, is convenient to processing and manufacturing, and material is less, and the processing charges cost descends obviously, and cost performance is more reasonable.
