Along with the progress of society, numerical control horizontal gear hobbing machine industry has had larger development, therefore has higher requirement to the work piece holder in numerical control horizontal gear hobbing machine.
In the prior art, the ringfeder of the internal expansion type fixture in numerical control horizontal gear hobbing machine makes ringfeder externally strut the workpiece with endoporus is fixed location by fixture is inner stressed, the ringfeder end that the stress point of internal expansion type fixture ringfeder when stationary positioned workpiece of this spline structure is only limitted to, make ringfeder discontinuity, and stressed also relatively little when stationary positioned of workpiece, during processing larger workpiece, workpiece makes workpiece easily produce because power suffered when fixture is fixed workpiece is less to rock under High Rotation Speed, the machining accuracy causing workpiece to be processed in numerical control horizontal gear hobbing machine reduces.
Summary of the invention
The ringfeder uniform force of a kind of internal expansion type fixture made in numerical control horizontal gear hobbing machine that the purpose of this utility model is deficiency in order to solve above-mentioned technology and provides, improves the internal expansion type fixture for numerical control horizontal gear hobbing machine of machining accuracy.
The internal expansion type fixture for numerical control horizontal gear hobbing machine designed by the utility model, comprise the main shaft for fixture rotation on numerical control horizontal gear hobbing machine, described main shaft runs through and is provided with rod assembly, this rod assembly is fixed with tensioner screw rod, this tensioner screw rod and rod assembly are socketed with internal expanding seat simultaneously, and interfix between main shaft and internal expanding seat, the head cover of this internal expanding seat has ringfeder, and the end of ringfeder contacts at the head of tensioner screw rod, be provided with inner bevel in described ringfeder, the head of described internal expanding seat is provided with the outer oblique angle mutually mated with inner bevel.
In order to accurate positioning when workpiece is fixed, improve machining accuracy during work pieces process, the right side of internal expanding seat can be provided with and mate with described ringfeder the working panel used; Anti-feather key can be provided with between the head and ringfeder of internal expanding seat.
When workpiece is installed, workpiece is placed on ringfeder, utilize working panel to determine the depth of parallelism and the perpendicularity of workpiece, rod assembly stressed drive tensioner screw rod moves to the left, now the head of tensioner screw rod drives ringfeder to move to the left, and the angle direction that ringfeder also matches along inner bevel and outer oblique angle simultaneously moves the effect reaching the fixation workpiece that ringfeder externally struts.
In order to make clamp structure compact, spacing effect is played to pull bar and tensioner screw rod, be convenient to installation or removal, improve the Practical Performance of fixture, described rod assembly comprises pull bar and coupling sleeve, this coupling sleeve is placed in the centre bore of internal expanding seat, described tensioner screw rod and pull bar are all fixed on coupling sleeve, the outer surface of described internal expanding seat from top to bottom runs through and has bolt, the outer surface of described coupling sleeve is provided with the locating slot mated with bolt, and the bottom of this bolt is placed in locating slot.
The internal expansion type fixture for numerical control horizontal gear hobbing machine designed by the utility model, make the uniform force of ringfeder when fixation workpiece, during the location of workpiece, precision is higher, and power suffered when workpiece is fixed is also relatively large, when processing larger workpiece, workpiece is not easy generation and rocks, and improves the machining accuracy of numerical control horizontal gear hobbing machine when processing work.
