Description
Technical field
The utility model relates to frock clamp field, specifically, relates to a kind of major diameter ultrathin high accuracy pad car grinder clamps.
Background technology
Pad is exactly by high precision, and the flaky material of high rigidity is refining to be formed, and is usually used in adjustment and the measurement of precision die or accurate five metals, or as cushion block, is called fine gasket, be sometimes also mould pad or precision gap sheet.Pad, as a kind of seal member, is widely used in various equipment and assembly, and consumption in the assemblies such as flange is larger; Meanwhile, patch applications is when different equipment or assembly, and its concrete size and dimension is all different, therefore, selects the spacer processing device be applicable to just to seem particularly important.
Existing spacer processing device is punch press, this punch press comprises actuating unit, actuating unit is provided by external power source usually, actuating unit drives the first mould to move up and down, second mould is fixed on the appropriate location on punch press, and the first mould surface relative with the second mould has the shape matched, so that the first mould and the second mould can obtain expecting the pad of specification and shape during punch press work after mutually extruding; In the process of pad, start punch press, actuating unit drives the first mould to move near the direction of the second mould, and there is predetermined shearing force, the motherboard of pad is positioned between the first mould and the second mould, and cut under the effect of the shearing force of two moulds, thus obtains pad.
And for the extra-thin pad of major diameter by punch press direct pressing pad not easy-formation, inefficiency, so general factory is first polished to it by lathe for the extra-thin pad of major diameter, then cuts.
Through retrieval, patent ZL 200810121605.0, denomination of invention is: for the fixture of grinding spherical pad, fixture in this patent, comprise the flange (1) and chuck (5) that are fixedly connected with, the lateral surface of described chuck (5) or medial surface are spherical arc (2) and sphere centre is positioned on the rotation (6) of fixture, this spherical arc radian is identical with the spherical arc radian of spherical washer, is provided with solenoid (4) in described chuck (5).Fixture in this patent is used for grinding spherical pad, is not suitable for the extra-thin pad of major diameter.
Utility model content
The technical problem solved
For overcoming the technical problem existed in prior art, the utility model provides a kind of major diameter ultrathin high accuracy pad car grinder clamps, this clamp structure is simple, easy to operate and can carry out quick-clamping and fixing to pad, is convenient to lathe and polishes and fine finishining to pad.
Technical scheme
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
Major diameter ultrathin high accuracy pad car grinder clamps, comprises jig main body, set bolt, trimming bolt, fine setting movable block; The side of described jig main body is provided with four through holes, described set bolt matches with through hole and is fixed on jig main body by workpiece, described jig main body be circumferentially provided with fine setting through hole, described trimming bolt carries out inching by matching with fine setting through hole to workpiece, and trimming bolt is provided with the fine setting movable block matched with it.
Further, the side of described jig main body is provided with bindiny mechanism, and bindiny mechanism is connected with lathe dop.
Further, described fine setting through hole is located on the excircle of jig main body uniformly, and the number of fine setting through hole is 8 to 24.
Further, be provided with groove, be provided with limited block in groove in described fine setting movable block, trimming bolt can be in rotary moving in groove.
Beneficial effect
Compared with prior art, the utility model has following remarkable advantage:
1, pad is first fixed on jig main body by four through holes being evenly distributed on jig main body side and the set bolt that matches with it thereof by the utility model, in lathe polishing gasket surface process, pad and jig main body side there will be loosening, to be adjusted by trimming bolt again and the limited block of finely tuning in movable block can make pad and workpiece keep side tightly to fit, that then carries out next step to workpiece adds polishing work, polished pad a side carrying out another side polishing processing, finally pad is cut, not easily there is breakage in pad, shaping efficiency is high, substantially increase production efficiency.
2, the utility model is applicable to the processing of major diameter (Ф 500-Φ 1500mm) ultrathin (1mm-4mm) high accuracy alloy pad, polishing pad out can reach surface roughness Ra 0.4, spacer thickness tolerance reaches below 0.03mm, outer diameter tolerance is at below 0.05mm, and pad precision is high.
3, the size of jig main body of the present utility model can adjust according to the pad of different size, large-sized pad also adaptability is increased to the quantity of fine setting through hole and trimming bolt, the structure of fixture of the present utility model is simple, easy to operate, can realize the clamping of workpiece fast and fix.
