Description
Technical field
The utility model relates to a kind of clamp for machining, especially a kind of thin-wall face gear clamp for machining.
Background technology
Face gear drive (Face Gear Drive) is the gear drive that a kind of roller gear is meshed with conical gear, because aspects such as it is little, in light weight at volume, high bearing capacity, low noise, high reliability, long-life have shown great advantage, and are widely used in the middle of the precision drive and new forms of energy transmission system of the differential gear train on the power dividing of aviation main reducing gear, milling machine spindle, the automobile, the transmission of joint of robot, little sideshake.
At present, show from external technical data, the face gear can adopt the processing method processing of gear shaping, gear hobbing and roll flute, because external opposite gear machining technology is carried out and is holded in close confidence, cause the face gear machining technology domestic also not on top of, just carried out face gear Gear Shaping Study on Technology.
In the process of thin-wall face gear, because the part poor rigidity, weak strength very easily produces distortion at clamping and process, is difficult to guarantee machining accuracy.Thin-wall face gear as shown in Figure 1, face gear tooth place inner and outer diameter is respectively 160.1mm and 170mm; Thin-walled place internal diameter is 162.9mm, and external diameter is 170.7mm, and material is LY12, is typical thin-walled parts.In the thin-wall part process, the most serious by stress deformation to the influence of part processing precision, therefore how to design anchor clamps that simple, the convenient face gear that can guarantee that again thin-wall face gear processes under stress deformation of a cover satisfies machining accuracy and be a technical barrier in the engineering.
Summary of the invention
The purpose of this utility model is to provide a kind of thin-wall face gear Gear Shaping special fixture, these anchor clamps are at the design feature of thin-wall face gear, design a kind of compact conformation, face Gear Processing anchor clamps easy to loading and unloading, guarantee simultaneously in process, reduce or eliminate because the influence of stress deformation processes the thin-wall face gear that satisfies required precision.
The purpose of this utility model is achieved through the following technical solutions:
The utility model comprises clamp body, axial locking screw, pressing plate, dog screw, one end of described clamp body is provided with the boss that can be installed in the workbench centre bore, the other end is provided with the annular boss that thin-wall face gear is installed, annular boss is provided with the fixedly pressing plate and the axial locking screw of thin-wall face gear, and described clamp body periphery also is provided with groove.The center of described clamp body also is equipped with the measurement axle coaxial with clamp body.The boss that is installed in the workbench centre bore on the described clamp body can also be arranged on the aligning axle, and described aligning axle is installed on the clamp body by dog screw.
Described clamp body and thin-wall face gear are matched in clearance.
Described pressing plate and axial locking screw are uniform 6.
The groove that described clamp body periphery also is provided with is uniform 6.
Described dog screw is uniform 3.
The utility model is in use at first tackled thin-wall face gear to be processed and is improved, and increasing in inside has web, is provided with and the corresponding installing hole in clamp body annular boss screwing hole (Fig. 2) on the web.After Gear Processing was finished, web was removed in excision again.
Design has annular boss on the clamp body of the present utility model, and by pressing plate and axial locking screw, can thin-wall face gear to be processed be installed on the anchor clamps, realization radially has axial effective location; Owing to the effect of clamp body, can offset the stress deformation of part to be processed in process; The center of clamp body also is equipped with the measurement axle coaxial with clamp body, it is measurement for convenience of face gear in the process, in use, can adjust change to the length of measuring axle according to the working depth of actual face gear, operation is simple, easy to operate; Clamp body and thin-wall face gear are matched in clearance, can make thin-wall face gear to be processed easy to loading and unloading; Pressing plate and axial locking screw, groove are arranged to uniform 6 and dog screw and are arranged to uniform three, can realize positioning security, reliable lock.The utility model compact conformation, easy to loading and unloading, gear shaping, gear hobbing, roll flute that has overcome thin-wall face gear etc. adds the stressing influence in man-hour, and simultaneously, the utility model can also be applied in the process of thin-wall part of other type.
