Description
Technical field
The utility model relates to a kind of frock clamp, particularly relates to the frock clamp that the endoporus grinding of a kind of automobile axle shaft two ends uses.
Background technology
The two ends of automobile axle shaft have centre bore to need grinding, two when carrying out lathe process to automobile axle shaft, general way adopts the direct clamping disk(-sc) portion of scroll chuck, and then hold out against the other end with thimble, there is following defect in this mode: push up too tight as top, be heated during work pieces process and extend to be obstructed and also will cause flexural deformation, as top top get Tai Song, then stability is poor again, and half shaft centre line and thimble cannot be ensured on the same line, cause machining benchmark to be forbidden, percent defective is higher; Gripping is inconvenient, affects operating efficiency.
Utility model content
Because the above-mentioned defect of prior art, when technical problem to be solved in the utility model is to provide a kind of automobile axle shaft two ends endoporus attrition process, good stability, workpiece deformation is little, and positioning datum is unified, handled easily, efficiency high frock clamp.
For achieving the above object, the utility model provides a kind of frock clamp, it is characterized in that, comprises the base of fixture, pressing plate, two locking nuts; The left and right sides of described base upper surface is all arranged with back-up block, support cylinder and cushion block in parallel; Described back-up block top is provided with two the first parallel installing rings; Described support cylinder top is provided with the first arc-shaped notch of clamping automobile axle shaft bottom; Described cushion block Upper vertical direction is provided with threaded rod; The left and right sides of described pressing plate bottom face is all arranged with the second installing ring in parallel, compresses cylinder and U-type groove mouth; Described compression cylinder bottom is provided with second arc-shaped notch on clamping automobile axle shaft top; The second described installing ring is arranged on two the first installing rings centres and forms turning joint by bearing pin assembly connection; Described threaded rod realizes tightening or unclamping by threaded engagement on locking nut and threaded rod through after U-type groove mouth again.
Further, be also provided with the second breach in the middle part of described pressing plate, it is as observation panel, conveniently observes constantly the clamped condition of automobile axle shaft when fixture uses, and also reduces pressing plate overall weight simultaneously, cost-saving.
Further, on described pressing plate, the left and right sides of the second breach is provided with handle, handled easily.
Compared to existing technology, the beneficial effects of the utility model are: the utility model structure is simple, easy to operate, it adopts a pressing plate that two positions on automobile axle shaft just can be made to be compressed simultaneously, good stability and to realize benchmark same, clamped position, not at both sides top end, is out of shape little during work pieces process, thus the position error of central shaft on minimizing automobile axle shaft, improve crudy and production efficiency.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figures 1 to 6, a kind of frock clamp, is characterized in that, comprises the base 1 of fixture, pressing plate 2, two locking nuts 3; The left and right sides of described base 1 upper surface is all arranged with back-up block 11, support cylinder 12 and cushion block 13 in parallel; Described back-up block 11 top is provided with two the first parallel installing rings 111; Described support cylinder 12 top is provided with the first arc-shaped notch 121 of clamping automobile axle shaft 10 bottom; Described cushion block 13 Upper vertical direction is provided with threaded rod 14; The left and right sides of described pressing plate 2 bottom face is all arranged with the second installing ring 22 in parallel, compresses cylinder 21 and U-type groove mouth 23; Described compression cylinder 21 bottom is provided with second arc-shaped notch 211 on clamping automobile axle shaft 10 top; The second described installing ring 22 is arranged on two the first installing rings 111 centres and forms turning joint by bearing pin 4 assembly connection; During assembling, its bearing pin 14 passes through successively through the first through hole 112 on the second through hole 221 on the first through hole 112, second installing ring 22 on the first installing ring 111 and another the first installing ring 111; Described threaded rod 14 realizes tightening or unclamping by threaded engagement on locking nut 3 and threaded rod 14 through after U-type groove mouth 23 again; The second breach 24 is also provided with in the middle part of described pressing plate 2; On described pressing plate 2, the left and right sides of the second breach 24 is provided with handle 25.
As shown in Figures 1 to 6, during use, base 1 is fixed on the workbench of attrition process lathe, hand-held handle 25, two the second installing rings 22 on such pressing plate 2 rotate and are greater than 90 degree afterwards with regard to having reserved operating space to the installation of automobile axle shaft 10 under twisting force and by hinge arrangement, now automobile axle shaft 10 are placed in first arc-shaped notch 121 on two support cylinder 12 tops; It is firmly made to rotate pressing plate 2 by rotary hinge structure to pressing plate 2 upper handle 25 again, second arc-shaped notch 211 of such compression cylinder 21 bottom will with automobile axle shaft 10 upper contact, now threaded rod 14 also can pass U-type groove mouth 23 simultaneously, finally locking nut 3 is assembled to the upper end of threaded rod 14, and rotational lock nut 3 moves downward and automobile axle shaft 10 is locked, finally make two the second arc-shaped notch 211 and two the first arc-shaped notch 121 that the top and the bottom at automobile axle shaft 10 two ends are all compressed, therefore operation is few for non-cutting time, good stability, is out of shape little; Because two the first arc-shaped notch 121 centers on the base 1 of fixture are coaxial with the alignment of shafts of lathe, and two the first arc-shaped notch 121 maintain static, so when automobile axle shaft clamps, the center line of the two ends endoporus on its automobile axle shaft 10 is all consistent with machine tool chief axis, therefore it can guarantee the accuracy of its machining benchmark.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technical staff in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
