The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Embodiment one
Referring to Fig. 1, Fig. 2, a kind of gradient adjustable clamp comprises base 100 and clamp body 200.
Referring to Fig. 3, described base 100 is provided with one group of coaxial bearing pin installing hole 110 and four groups of coaxial pitch adjustment holes 120.Referring to Fig. 4, the downside of described clamp body 200 also be provided with one group of coaxial bearing pin installing hole 210 and and base on the pitch adjustment hole 220 of equal number.Bearing pin installing hole 110 on the described base 100 equals the bearing pin installing hole 210 of clamp body 200 and the centre-to-centre spacing in corresponding each pitch adjustment hole 220 with the centre-to-centre spacing in each pitch adjustment hole 120.
Described clamp body 200 is arranged at the top of base 100, is provided with a bearing pin 300 in the bearing pin installing hole 110 of described base 100 and the bearing pin installing hole 210 of clamp body 200, and clamp body 200 is connected with base 100; Fitted position tolerance fit between described base 100, clamp body 200, the bearing pin 300 is tighter matched in clearance.The relative position that corresponding each the pitch adjustment hole 220 of each pitch adjustment hole 120 of described base and clamp body overlaps is all inequality, also be provided with a bearing pin 300 in the pitch adjustment hole that on base 100 and clamp body 200, coincides, one end of bearing pin 300 is provided with external screw thread, and external screw thread is provided with a nut 800.
The upper surface of described clamp body 200 is " L " shape, the side of the below of " L " shape is provided with three groups of shoulder holes 230 that upper surface upper side diameter is little, the opposite side diameter is big, the bottom, hole that described diameter is big is provided with a compression spring 400, with the compression spring 400 adjacent pressing plates 500 that also are provided with.Referring to Fig. 5, described pressing plate 500 is cylindric, and the sidewall of cylinder is provided with the end face baffle plate vertical with cylindrical linear 510, and it is tighter matched in clearance that described outside diameter of cylinder cooperates with the dimensional tolerance of shoulder hole 230; The aperture in the hole that diameter is little in the endoporus 520 of described cylinder and the clamp body shoulder hole 230 equates; Have a housing screw 600 to pass in the shoulder hole 230 of described clamp body and the endoporus 520 of pressing plate 500, the end of thread of described housing screw 600 is provided with nut 700.
Operation principle of the present utility model is as follows: clamp body 200 and base 100 by base bearing pin installing hole 110 and the bearing pin 300 in the bearing pin installing hole 210 of clamp body be connected; Making clamp body 200 can be that fulcrum rotates around base 100 with bearing pin 300.According to the gradient of wanting processing parts 900, determine base 100 with which group pitch adjustment hole of clamp body 200 overlaps, corresponding relation for convenient identification part gradient and the utility model pitch adjustment hole, next door in base pitch adjustment hole is provided with the gradient numeric indicia, indication according to the gradient numeric indicia is provided with another root bearing pin 300 in the pitch adjustment hole that base 100 and clamp body 200 coincide, for avoiding bearing pin 300 play in the pitch adjustment hole, the end of bearing pin is fixing by a screw thread and a nut 800; At this moment, the gradient of a kind of gradient adjustable clamp inclination of the utility model is identical with the gradient of the part 900 that will process.The part 900 that will process is positioned in the formed concave surface 240 in " L " shape upper surface of clamp body 200, regulates pressing plate 500 with nut 700 and housing screw 600 again, accurately locatees and clamps by the part 900 that pressing plate 500 will be processed.Then, part 900 is processed, after machining, unclamped nut 700, pressing plate 500 outwards moves with nut under the effect of compression spring 400, and part 900 is unclamped, and just can unload part 900.
The utility model can be provided with the pitch adjustment hole of varying number according to the kind of the gradient of parts in small batch, such as, the gradient of the parts in small batch that process has two kinds, then two groups of coaxial pitch adjustment holes of relative set on base and clamp body; If the gradient of the parts in small batch that will process has five kinds, five groups of coaxial pitch adjustment holes of relative set on base and clamp body then, the utility model just can be used for the processing of the part of corresponding different gradient kinds, so versatility is good, thereby the preparation amount that the part that reduces multi-varieties and small-batch is produced, shorten the preparatory period, reduce the processing cost of part.In use, tighten the nut of housing screw and the part between clamp body and the pressing plate can be finished location and clamping, after part processing is good nut is unclamped, then the effect lower platen at the compression spring just moves with nut, part is unclamped, thereby the location of part is convenient, accurate, improved the machining accuracy of part, and simple to operate, part easy accessibility, working (machining) efficiency height; The setting of compression spring also makes the moment of torsion that transmits in the part clamping process regulate, and overload protection function is arranged.The utility model compact overall structure, low cost of manufacture.
