Abstract
The utility model discloses an annular terminal surface spot facing work anchor clamps, its structure includes the anchor clamps bottom plate and in proper order by lower ring washer on the anchor clamps bottom plate of lower supreme setting, well ring washer, disc spring on, ring washer, eccentric wheel packing ring, handle and Y -type eccentric wheel, is equipped with the mandrel on the anchor clamps bottom plate, down ring washer, disc spring, go up ring washer and eccentric wheel packing ring from bottom to top the mandrel is located to the cover in proper order on, the Y -type eccentric wheel passes through hinge looks swing joint in mandrel top, Y -type eccentric wheel afterbody passes through bolt looks fixed connection with the handle, Y -type eccentric wheel and eccentric wheel packing ring material all adopt 20 steel, the handle can more change different length into according to the required packing force of actually holing, the mandrel top need not process the screw. After adopting above -mentioned technical scheme, through changing the handle, provide sufficient packing force in the time of can driling for different work pieces, Y -type eccentric wheel compact structure easy dismounting has improved production efficiency greatly.
Description
Technical field
The utility model relates to fixture, particularly relates to a kind of annular end face hole processing clamp.
Background technology
In prior art, common annular end face hole processing clamp comprises clamp bottom board, lower ring washer, middle ring washer, upper ring washer, butterfly spring, axle, open washer, nut.Fixture is the screwed tight by nut and axle top, is compressed by butterfly spring by open washer and ring washer, makes its diameter become large, from inner surface stretching annular workpieces.But prior art central shaft top needs machining screw, and compressed by the mode of fastening nut, there is Post isothermal treatment need consider screw thread protection, and heat treatment comparatively bothers, and changes workpiece consuming time longer, the problem that production efficiency is not high.
Utility model content
For the problems referred to above, the utility model provides a kind of annular end face hole processing clamp.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of annular end face hole processing clamp, the lower ring washer that its structure comprises clamp bottom board and is arranged on from the bottom to top successively on clamp bottom board, middle ring washer, butterfly spring, upper ring washer, eccentric wheel packing ring, handle and fork-shaped eccentric wheel, described clamp bottom board is provided with axle, described lower ring washer, butterfly spring, upper ring washer and eccentric wheel packing ring are from bottom to top sheathed in axle successively, described fork-shaped eccentric wheel is movably connected on axle top mutually by hinge, described fork-shaped eccentric wheel afterbody and handle are fixedly connected by bolt, described fork-shaped eccentric wheel and eccentric wheel gasket materials all adopt 20 steel.
Further, described handle the thrust needed for reality boring can be replaced with different length.
Further, described axle top does not need machining screw.
From the above-mentioned description to the utility model structure, compared to the prior art, the utility model tool has the following advantages:
1, a kind of annular end face hole processing clamp that the utility model provides changes screw thread compressing structure of the prior art into eccentric wheel self-locking compressing structure, makes workpiece disassembling operations convenience, clamping rapidly, improves production efficiency.
2, a kind of annular end face hole processing clamp of providing of the utility model, by being releasable connection by handle and fork-shaped eccentric wheel, handle the thrust needed for reality boring can be replaced with different length, has widened the occasion that fixture can be tried out.
3, a kind of annular end face hole processing clamp of providing of the utility model, by axle top being set as the screw thread not needing to process, the consideration of double thread protection when avoiding axle heat treatment, reduces heat treated difficulty, has saved cost.
Accompanying drawing explanation
The accompanying drawing forming a application's part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of a kind of annular end face hole processing clamp of the utility model;
Fig. 2 is the structural representation of annular end face boring grab of the prior art.
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.
Embodiment
With reference to figure 1, a kind of annular end face hole processing clamp, the lower ring washer 2 that its structure comprises clamp bottom board 1 and is arranged on from the bottom to top successively on clamp bottom board 1, middle ring washer 3, butterfly spring 4, upper ring washer 6, eccentric wheel packing ring 7, handle 8 and fork-shaped eccentric wheel 9, clamp bottom board is provided with axle 5, lower ring washer 3, butterfly spring 4, upper ring washer 6 and eccentric wheel packing ring 7 are from bottom to top sheathed in axle 5 successively, fork-shaped eccentric wheel 9 is movably connected on axle 5 top mutually by hinge, fork-shaped eccentric wheel 9 afterbody and handle 8 are fixedly connected by bolt, fork-shaped eccentric wheel 9 and eccentric wheel packing ring 7 material all adopt 20 steel, handle 8 thrust needed for reality boring can be replaced with different length, axle 5 top does not need machining screw.A kind of annular end face hole processing clamp that the utility model provides, by changing screw thread compressing structure of the prior art into eccentric wheel self-locking compressing structure, make workpiece disassembling operations convenient, clamping rapidly, improve production efficiency, further, by being releasable connection by handle 8 and fork-shaped eccentric wheel 9, handle 8 thrust needed for reality boring can be replaced with different length, widen the occasion that fixture can be tried out, further, by axle 5 top being set as the screw thread not needing to process, the consideration of double thread protection when avoiding axle 5 heat treatment, reduce heat treated difficulty, save cost.
The utility model realizes the clamping to ring tool mainly through eccentric wheel compressing structure.Operating process is as follows:
(1) clamping workpiece
First assemble fixture during use, load onto workpiece, then by handle 8, toward pressing down, namely disk spring 4 compresses by eccentric wheel packing ring 7 and upper ring washer 6 by fork-shaped eccentric wheel 9, makes it diameter swell, from inner surface swelling workpiece, just can carry out Drilling operation afterwards.
(2) workpiece is retracted
After having bored hole, up lifted by handle 8, can unclamp, disk spring 4 rebounds automatically, and diameter diminishes, thus easily takes off workpiece.
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.
