Description
Technical field
The utility model relates to a kind of fixture, especially for the elastic sheet fixture of machining gears.
Background technology
At present, when machining gears, multiplex clamping with three-jaw chuck, spanner need be operated and move claw by transmission mechanism, not only clamp inconvenience, efficiency is low, and can only tooth top be clamped, cannot aligning, positioning precision poor, the wearing and tearing of fixture are very fast, are difficult to service life meet the demands.
Summary of the invention
The purpose of this utility model is for prior art above shortcomings, provides a kind of elastic sheet fixture, and it has, and clamping is convenient, efficiency is high, the advantage of long service life, and positioning precision is high.
For achieving the above object, elastic sheet fixture of the present utility model, comprise clamp body, slide through pull bar in the middle part of clamp body, it is characterized in that the elastic sheet being provided with band annular sidewall in clamp body front, its annular sidewall and clamp body connect firmly, one guide post connects with pull bar through in the middle part of elastic sheet, the front end of guide post is pressed on elastic sheet front end face, clamp body is associated with more than one backstay through elastic sheet, backstay is fixedly connected with positioning disk, the elastic sheet outside positioning disk is provided with at three circumferentially uniform claws.
In use, by pulling pull bar to make guide post pull back the middle part of elastic sheet, elastic sheet produces distortion and three claws is inwardly shunk the utility model, can clamping work pieces; After pull bar resets, the distortion of elastic sheet also disappears, and claw resets and unclamps workpiece; The utility model is by pulling pull bar holding workpiece, and clamping is convenient, efficiency is high, and transmission mechanism-free, wear and tear little, long service life;
As further improvement of the utility model, three briquettings are provided with on rear side of elastic sheet, on front side of elastic sheet, correspondence is provided with three locating pieces, the more than one positioning sleeve through elastic sheet is provided with between briquetting and corresponding locating piece, the screw of more than one is connected with locating piece by screw thread through briquetting, positioning sleeve, locating piece is equipped with T-slot, is provided with T-shaped bar in T-slot, and described claw is connected with corresponding T-shaped bar by screw; Be convenient to dismounting claw, and pass through the radial position of T-shaped bar adjustable claw, improve versatility;
As further improvement of the utility model, inside each claw, be equipped with the plug contacted with it; During clamping, be placed in by plug in teeth groove, claw compresses plug, and located by plug and adjacent two face, adjusting center, positioning precision are high;
As further improvement of the utility model, the annular sidewall of clamp body and elastic sheet is by several screw attachment, and guide post and pull bar are by thread connection, and backstay and clamp body are by thread connection, and positioning disk and backstay pass through screw attachment; Front end and the elastic sheet of guide post also pass through screw attachment; Be convenient to mounting or dismounting;
In sum, the utility model has the advantage that clamping is convenient, efficiency is high, be convenient to mounting or dismounting, long service life, and positioning precision is high.
