Description
Technical field
The utility model relates to machining manufacturing technology field, is specifically related to a kind of fixture of hard car axle shaft gear angle head cylindrical.
Background technology
Automobile half axle gear is a kind of straight bevel gear, and when assembling, installed surface, axle journal and the flank of tooth coordinate with adjacent elements, and its quality of fit directly affects the transmission quality of automobile half axle gear.And installed surface and axle journal are reference for assemblings, therefore adding man-hour, the tooth runout being benchmark with installed surface and axle journal requires high.
Automobile half axle gear will carry out necessary heat treatment after flank profil is shaped, and after heat treatment, teeth portion is no longer processed, and carries out grinding or hard Vehicle Processing to end face and axle journal.Wherein hard Vehicle Processing technique due to its efficiency high, environmental protection, the Product Precision of processing is high, stable, to advantages such as operating personnel's skill set requirements are low, is used widely.The fixture used in existing processing adopts tooth shape locating, and three-jaw compresses the fixture of the locking mode of back cone, and this clamp structure is complicated, manufacturing cost efficiency that is high, clamping is on the low side.
Summary of the invention
The purpose of this utility model is to provide a kind of fixture of hard car axle shaft gear angle head cylindrical, the simple low cost of manufacture of this clamp structure, and positioning stablity is reliable, and clamping efficiency is high.
For achieving the above object, the technical scheme that the utility model adopts is: the fixture of hard car axle shaft gear angle head cylindrical, comprises clamp body.Described clamp body one end is fixed on lathe spindle flange, and the other end arranges tooth shape locating head; Described tooth shape locating head is arranged the toothed region with axle shaft gear flank engagement; Described clamp body is provided with through hole, arranges pull bar in through hole; Described pull bar one end connects lathe pull bar, and the other end stretches out the intermediate throughholes of tooth shape locating head; Described pull bar stretches out tooth shape locating head part and to removably connect packing ring.
Preferred: described pull bar stretches out one end of the intermediate throughholes of tooth shape locating head, comprise the thin neck that size is less; Described packing ring is open washer, is set on thin neck.
Preferred: described tooth shape locating head is coordinated by seam small―gap suture with clamp body, and tooth shape locating head is fixed by screws on clamp body.
Preferred: described pull bar one end is connected with lathe pull rod screw, the pull bar other end coordinates with tooth shape locating head endoporus small―gap suture.
The utility model has following beneficial effect: the fixture provided is with axle shaft gear tooth shape locating, and positioning stablity is reliable.Clamp body is provided with through hole, arranges pull bar in through hole, and pull bar stretches out tooth shape locating head part and to removably connect packing ring.When using this fixture, axle shaft gear is contained on tooth shape locating head, is compressed the axle journal end face of axle shaft gear by pull bar band washer, complete clamping.In clamping process, needed for pull bar, displacement is little, and therefore clamp body length is shorter, fixture good rigidly.And convenient mounting and clamping, quick, be particularly suitable for the hard Vehicle Processing after axle shaft gear heat treatment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the fixture of hard car axle shaft gear angle head cylindrical, comprises clamp body 1.Described clamp body 1 one end is fixed on lathe spindle flange, and the other end arranges tooth shape locating head 2.Described tooth shape locating head 2 is arranged the toothed region with axle shaft gear 5 flank engagement.Described clamp body 1 is provided with through hole, arranges pull bar 4 in through hole; Described pull bar 4 one end connects lathe pull bar, and the other end stretches out the intermediate throughholes of tooth shape locating head 2; Described pull bar 4 stretches out tooth shape locating head 2 part and to removably connect packing ring 3.When using this fixture, axle shaft gear 5 is contained on tooth shape locating head 2, is compressed the axle journal end face of axle shaft gear 5 by pull bar 4 with washer 3, complete clamping.This fixture is with axle shaft gear 5 tooth shape locating, and positioning stablity is reliable.In clamping process, needed for pull bar 4, displacement is little, and therefore clamp body 2 length is shorter, fixture good rigidly.And convenient mounting and clamping, quick, be particularly suitable for the hard Vehicle Processing after axle shaft gear heat treatment.
Preferably, described pull bar 4 stretches out one end of the intermediate throughholes of tooth shape locating head 2, comprises the thin neck 41 that size is less; Described packing ring 3 is open washer, is set on thin neck 41.The thin neck 41 that size is less is set, pull bar 4 can be avoided to damage the flank of tooth of axle shaft gear 5, also can good retaining washer 3, to compress axle shaft gear 5.Packing ring 3 hardness is less, and the damage of packing ring 3 pairs of axle shaft gears 5 when avoiding clamping, ensures the crudy of axle shaft gear 5.And open washer is convenient to place and change.Described packing ring 3 also can be select ring washer, and now for the ease of changing, end head 42 and pull bar 4 are for being threaded.
Described tooth shape locating head 2 is coordinated by seam small―gap suture with clamp body 1, realizes radial centering; Tooth shape locating head 2 is fixed by screws on clamp body 1, realizes axial location.Like this by radial and axial location, well determine the position of tooth shape locating head 2, thus determine the position being contained in axle shaft gear 5 on tooth shape locating head 2, ensure that the Product Precision after processing.Described pull bar 4 one end is connected with lathe pull rod screw, and pull bar 4 other end coordinates with tooth shape locating head 2 endoporus small―gap suture.
The fixture that the utility model provides, it is installed and use step can be:
First the clamp body 1 installing tooth shape locating head 2 is arranged on lathe, with table centering.The plane in tooth shape locating head 2 detection reference face is beated with circular runout all in 0.01mm.Detect with master gear, guarantee master gear end face run-out, circular runout are no more than 0.015mm.Be contained on lathe by pull bar 4, axle shaft gear 5 is contained in after on tooth shape locating head 2, loads onto open washer.Start lathe hydraulic clamp button, make pull bar 4 to left movement, pull bar 4 compresses open washer, completes clamping.After process finishing, start lathe hydraulic unlock button, take off open washer, take off the axle shaft gear 5 processed.
