Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The utility model carries out drilling operating after clamping major axis class knuckle.As shown in Figure 1, it forms by body 100 and from the axle head 200 that body 100 protrudes so-called major axis class slewing journal structure, and axle head 200 is vertical with body 100.So-called drilling operating needs in axle head 200, bore a through circular hole.Effect of the present utility model is to be fixed knuckle, is alignd with the bit central of drilling machine in axle head center.
As shown in Figure 2, the utility model forms primarily of pedestal 1, lower locating piece 2, spring 3, upper locating piece 4, lower platen 5, top board 6 and block 7.The shape of lower locating piece 2, spring 3 and upper locating piece 4 is mated with the chamber of pedestal 1, three is superimposed to be successively arranged in chamber, and usually, lower locating piece 2, spring 3, upper locating piece 4 and chamber are all circular configuration, certainly, each part mentioned above also can adopt square shape structure to realize.
Lower platen 5 and top board 6 are individually fixed in side, face and the bottom side of pedestal 1.During concrete enforcement, both generally adopt the mode of screw locking to be fixed on pedestal 1.Lower locating piece 2, spring 3 and upper locating piece 4 can be defined in chamber in the mode of pressurized by both, namely the mode of so-called pressurized is that spring 3 extrudes by lower locating piece 2 and upper locating piece 4, compress on lower platen 5 at the lower surface of the situation not being subject to external force locating piece 2 at present, the upper surface of upper locating piece 3 then compresses on top board 6.
Lower locating piece 2, upper locating piece 4 are for clamping the axle head of knuckle, and therefore, the middle part of lower locating piece 2 is provided with first hole clipping 8 of mating with the nose shape of axle head, and the middle part of upper locating piece 4 is then provided with second hole clipping 9 of mating with the root shape of axle head.First hole clipping 8 and the second hole clipping 9 can, respectively by the head of axle head and root clamping, make knuckle entirety be fixed.In order to reach better clamping effect, the madial wall of the first hole clipping 8 is provided with the outstanding madial wall for the first inclined-plane 13, second perforate 9 clamping axle head and is provided with outstanding the second inclined-plane 14 for clamping axle head.
The middle part of lower platen 5 is provided with the first through hole 10, and the middle part of top board 6 is provided with the second through hole 11.Second through hole 11 is inserted in chamber for axle head, its size is between upper locating piece 3 and the second hole clipping 9, guarantee that upper locating piece 3 can not be emerged from the second hole clipping 9, in order to increase the active strokes of upper locating piece 3, the outer ledge of upper locating piece 3 upper surface is provided with the slot to make way 12 mated with the second through hole 11.First through hole 10 provides axle head head through the space of inserting further after the first hole clipping 8, and its size, between lower locating piece 2 and the first hole clipping 8, guarantees that lower locating piece 2 can not be emerged.
During concrete use, as shown in Figure 3, base central is alignd with drilling machine center, the axle head of knuckle workpiece is inserted in the chamber of pedestal through top board above pedestal, slight firmly pressing down makes the head of axle head be clamped by the first hole clipping of lower locating piece, and upper locating piece upwards lifts under the action of the spring and the root of axle head is clamped by the second hole clipping.After completing above-mentioned steps, knuckle can carry out spacing, and spacing rear axle head is arranged according to vertical mode, and its central shaft aligns with the center of drill bit.
After lower locating piece and upper locating piece can make knuckle be fixed, axle head keeps vertical, and block 7 is for guaranteeing that knuckle can not follow rotation when holing.Particularly, block 7 entirety is bar list structure, preferably adopts stud to realize, and this block 7 is vertically fixed on pedestal 1 through top board.The body of knuckle can be provided with some outward extending lever arms, when knuckle is fixed on fixture, block 7 can be punctured between lever arm, plays the effect preventing knuckle from following bit.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
