Abstract
The utility model relates to a nut opening and closing type fast tightening bench vice, which is characterized in that a threaded rod and a half nut are provided with sawtooth threads and the meshing is adopted with a switching mechanism. Simultaneously, a cam and a cam sleeve are connected in an elastic embedding way and the cam sleeve and the threaded rod are adopted with sliding key joint. The rapidity of tightening is achieved and the requirements the requirements for the clamping stroke by the bench worker operations such as assembly, sheet-metal forming, etc., can be satisfied.
Description
The utility model belongs to small tool.
The jaw folding of existing bench vice relies on screw rod, nut transmission, and the speed of levelling jaw folding is very slow.I invent by unit " bench vice of clamping work pieces fast " patent No. 86207594 aspect quick clamping mechanism, also have No. 87213118 " the program control universal bench vices of clamping mechanical fast " of the Decree of Patent Office of China.Foregoing invention has solved the problem of quick levelling jaw folding size, but then is not so good as common bench vice in the serviceability of pincers worker operating aspects such as assembling, sheet metal moulding.For example: the cover of length more than 30 millimeters is pressed in the corresponding hole, on common bench vice, can finishes by continuous rotation spanner.And on the quick bench vice of foregoing invention, the effective travel of the relative nut of screw rod is too little during because of clamping, needs repeatedly positive and negative direction to rotate spanner and just can finish troublesome poeration.In addition, also there is complex structure, shortcomings such as processing, assembling difficulty.
The purpose of this utility model is in order to overcome above-mentioned deficiency.
Nut open-close type fast clamping table vise mainly is made up of other part such as fixed caliper, moving caliper, spanner, screw rod, half-nut, cam pack, rocking bar.Cam pack comprises cam cover, cam, spring, steel ball and nut.The principal character of this bench vice is that screw rod and half-nut are saw-tooth thread, open-and-close mechanism has been adopted in engagement, after half-nut and the screw engages, spanner can be rotated continuously till the jaw closure, pincers worker operations such as assembling, sheet metal moulding can be satisfied clamping the requirement of stroke.Spring in the cam pack, steel ball connect cam and the embedding of cam cover formation elasticity, are not subjected to when cam under the situation of external force, and cam can rotate together in company with the cam cover, and when cam was subjected to external force, the two produced relative rotation.Keyway and key on cam cover and the screw rod can guarantee that moving caliper moves forward and backward in the cam cover with threaded, reaches quick levelling jaw openings of sizes.
Task of the present utility model is achieved in that (with reference to accompanying drawing)
Be processed with axial keyway on screw rod (12) and the cam cover (18), and key (15) is housed.Screw rod (12) can move axially in cam cover (18).The axial location of cam cover (18) is by the end face location of the upstanding edge and the half-nut (5) of pressing plate (8), cam (14) is contained on the cam cover (18), on cam (14) end face garden week, be drilled with two holes, mounting spring in the hole (16) and steel ball (17) by 180 degree directions.The convex shoulder end face of cam cover (18) is drilled with eight awl holes that equate at interval accordingly.
When rotating spanner (1) drive screw rod (12) rotation, drive cam cover (18) by key (15), because the spring (16) that is contained on the cam (14) is cheated the awl that steel ball (17) is pressed into cam cover (18) end face, thereby cam (14) is also along with cam cover (18) rotates together.
When clockwise rotating spanner (1), cam (14) forwards position shown in Figure 3 to and stops operating, and the linear portions of cam (14) gabarit contacts with moving caliper (2) inboard.In rotation process, the curve of cam (14) gabarit is partly depressed an end of rocking bar (7), the other end of rocking bar (7) is lifted, and with half-nut (5) jack-up, half-nut (5) is meshed with screw rod (12), be rotated further spanner (1), cam (14) will no longer rotate, and screw rod (12) moves axially with half-nut (5) generation that is installed in fixed caliper (4) square hole.The shaft shoulder of screw rod (12) promotes moving caliper (2), by jaw (3) workpiece is clamped.The stroke that clamps is unrestricted, can move to the jaw closure from maximum open always, and this existing quick bench vice can't be realized.
Loosen workpiece and should rotate counterclockwise spanner (1).Screw rod (12) reverses in half-nut (5), strain in the clamping process is disappeared, screw rod (12) drives cam (14) counter-rotating by key (15), cam cover (18), spring (16), steel ball (17) simultaneously, cam (14) forwards position shown in Figure 4 to, because of the linear portions of its gabarit contacts with another medial surface of moving caliper (4), and stop operating, half-nut (5) is thrown off with screw rod (12) under spring (9) pulling force effect.Push-and-pull spanner (1) just can drive moving caliper (2) and move forward and backward in fixed caliper (4), reaches the size of quick levelling jaw opening.
Embodiment of the present utility model is processed into one 4 inch bench vice by said structure, and trial effect is good, and clamping work pieces once only needs two seconds.
Description of drawings:
Fig. 1 is a structure chart of the present utility model.1 spanner, 2 moving calipers, 3 jaws, 4 fixed calipers, 5 half-nuts, 6 cam packs, 7 rocking bars, 8 pressing plates, 9 springs, 10 screws, 11 rocker shafts, 12 screw rods.
Fig. 2 is the cam pack cutaway view.13 garden nuts, 14 cams, 15 keys, 16 springs, 17 steel balls, 18 cam covers.
Fig. 3 is that cam is depressed rocking bar one end the position of colliding in flank of cam and moving caliper inboard in the bottom when clockwise rotating.
Fig. 4 is that the cam inhour is rotated at present portion and left rocking bar, another medial surface of flank of cam and moving caliper position of colliding.
Fig. 5 is that cam is depressed rocking bar and lifted half-nut, makes the position of half-nut and screw engages.
Fig. 6 is that cam leaves rocking bar, and half-nut is out-of-gear position under the spring tension effect.
