Background technology
On the planet bevel-gear spherical, all put radially oil groove, effectively improve the service condition of bevel planet gear.Because the design feature of bevel planet gear, this oil groove Milling Process difficulty is bigger, and location when being mainly reflected in Milling Process and clamping are difficult.Prior art adopts awl tooth location, pressing plate to clamp on milling machine, groove milling processing respectively then, and this technology can mill out qualified sphere oil groove.But groove of every milling will reorientate that installation technology once is not advanced, and the milling work efficiency is slow, and cost of manufacture is big, be not suitable for producing in batches.
Summary of the invention
The present invention is primarily aimed at the deficiencies in the prior art, proposes a kind of disposable location, swelling, the bevel-gear spherical oil-tank lathe milling fixture of difference groove milling on lathe.This clamp structure is simple, accurate positioning, compress reliable, milling is quick.
The present invention is achieved through the following technical solutions technical goal.
Bevel-gear spherical oil-tank lathe milling fixture, it comprises transmission mechanism, detent mechanism, indexing mechanism, clamp body and base.Described transmission mechanism is by hand wheel Driven by Coaxial worm screw and drive worm gear and the splined shaft that matches rotates.Described base bottom face is the plane, and base upper surface is provided with two risers at interval that are parallel to each other, and riser is provided with through hole supporting splined shaft.Described clamp body comprises the side's cover and the pivoted housing of matched in clearance.Described detent mechanism comprises expansion set, tooth template, pull bar and nut, and the tooth template is connected the pivoted housing large end face, and the built-in expansion set of tooth template cooperates with the pivoted housing endoporus.Described indexing mechanism comprises alignment pin, positioning sleeve and the index plate that cooperatively interacts, cover end, the positioning sleeve side of being fixedly connected on, and index plate is connected on the small end face of pivoted housing.Improvements are: placing the side's cover between base two risers is that the axle supporting is rotated with the splined shaft.Described expansion set endoporus axially inserts pull bar and passes from the index plate middle part, and pull bar expands expansion set outward by nut check.
In the said structure, be positioned at bevel gear to be processed on the tooth template by swelling in expansion set and the pull bar taper fit.Index plate is fixedly connected on the small end face of pivoted housing, and the restriction pivoted housing is with respect to the axial float of side's cover.
The present invention compared with prior art has following good effect:
1, interior swelling structure cooperates with the tooth template, accurate positioning, reliable clamping;
2, side's cover is by 2 supportings of splined shaft, and the bevel gear to be processed of cover end, the side of being in is that axle rotates with the splined shaft, and the radius of gyration equates that with bevel-gear spherical radius to be processed the sphere oil groove is milled into and describes easily;
3, index dial and tooth template are fixedly connected on two end faces of pivoted housing respectively, and indexing mechanism is directly controlled the rotation of pivoted housing with respect to side's cover, and calibration is accurate.
