Description

Process slim roller gear part gear grinding clamp
Technical field
The utility model belongs to metal cutting technology field, particularly relates to a kind of slim roller gear part gear grinding clamp.
Background technology
At present, on gear grinding machines during machining cylindrical gear, generally take the method processing of tapering or the clamping of nut compressing mandrel location.But when running into the little and thin roller gear in hole, as shown in Figure 5, due to the design feature that this type of roller gear centre bore is little, determine clamping tooling mandrel localization part thin, therefore bring difficulty to gear location, clamping.Simultaneously in order to meet the range of work of grinding machine bed, mandrel must ensure certain length, and namely the draw ratio of mandrel is greater than 5 usually, and the rigidity of clamping tooling will inevitably be caused very poor, when adding large deformation under the effect in thrust after mandrel locking.Have a strong impact on clamping precision and gear Accuracy of finish like this, made it be difficult to reach designing requirement, time serious, also there will be waste product.
Summary of the invention
The utility model provides a kind of and meets thin type gear Element Design regulation and required precision, increase substantially working (machining) efficiency and can adapt to the slim roller gear part gear grinding clamp produced in batches for solving in known technology the technical problem that exists.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:
Process slim roller gear part gear grinding clamp, it is characterized in that: comprise mandrel, spring ringfeder and carry out the clamping sleeve of axial locking for roller gear part, described mandrel is shaped with the boss for roller gear part axial location, the mandrel of boss side is shaped with the benchmark conical surface and external screw thread, described spring ringfeder is shaped with the inner conical surface and multiple groove that match with the mandrel benchmark conical surface, described clamping sleeve be circumferentially provided with multiple screwed hole.
The utility model can also adopt following technical scheme:
Described spring ringfeder outer circular shape and roller gear inner bore of part shape match.
Described clamping sleeve be circumferentially provided with 6 screwed holes.
The advantage that the utility model has and good effect are: because the utility model adopts technique scheme, namely the physical condition of hole machined has been completed according to roller gear parts character and this parts, design mandrel and spring ringfeder, under the compression of round nut, spring ringfeder spreading, make roller gear inner bore of part and its blind-mate, utilize clamping sleeve to lock roller gear part axial.The roll flute processing that the utility model not only can be cylinder thin type gear part provides and simplifies very much and manufacturing process easily, makes the processing of cylinder thin type gear part teeth portion on gear grinding machine bed possess the technological equipment can stablizing use; But also machining accuracy and the crudy of cylinder thin type gear part can be ensured, increase substantially the working (machining) efficiency of cylinder thin type gear part.

Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1-Fig. 4, process slim roller gear part gear grinding clamp, comprise mandrel 1, spring ringfeder 2 and clamping sleeve 3, described mandrel is shaped with the boss 1-1 for roller gear part axial location, the mandrel of boss side is shaped with benchmark conical surface 1-2 and external screw thread 1-3, described spring ringfeder is shaped with the inner conical surface 2-1 and multiple groove 2-2 that match with the mandrel benchmark conical surface, described clamping sleeve be circumferentially provided with multiple screwed hole 3-1.Described mandrel is matched with inner conical surface 2-1 in spring ringfeder 2 by benchmark conical surface 1-1, and its reference center is matched.
In the present embodiment, described spring ringfeder inwall is shaped with three uniform groove 2-2.
In the present embodiment, described spring ringfeder outer circular shape and roller gear inner bore of part shape match.
In the present embodiment, described clamping sleeve be circumferentially provided with 6 screwed holes, for installing interior hexagonal flower shape fillister head screw 5, and can revise the distortion that coupling mechanism force produces.
In the present embodiment, described spring ringfeder cylindrical is the involute spline felt relieved in the large footpath matched with processed gear part endoporus.If processed gear part is unthreaded hole, spring ringfeder cylindrical changes the cylindrical of matched in clearance with it into.
Operation principle of the present utility model is:
The feature little and thin according to roller gear part locating hole, gear grinding clamp designs problem to be solved and is to ensure that the benchmark of part location and fixture datum match and eliminate to lock and be out of shape.
Refer to Fig. 5 and Fig. 6, according to its using method of gear grinding clamp that above-mentioned principle is made, first roller gear part 6 is contained on the mandrel 1 of gear grinding clamp, be loaded on spring ringfeder 2, the inner conical surface 2-1 of spring ringfeder is matched with the benchmark conical surface 1-1 of mandrel, make the spline cylindrical of spring ringfeder match with the splined hole of processed roller gear part simultaneously, screw in round nut 4 pretension again, make the appropriate adjustments and continue the round nut axial locking of pretension, till the gap making spring ringfeder spreading eliminate between processed roller gear part.Namely promote spring ringfeder 3 by the external screw thread 1-3 of mandrel by round nut 4 to move axially along mandrel benchmark conical surface 1-2, simultaneously radial through groove 2-2 spreading.Then load onto clamping sleeve 3, then screw in round nut 4 and compress processed roller gear part 6.Processed roller gear part and gear grinding clamp are assembled and is arranged on gear grinding machines, with top very good and install clip, the end face run-out of the processed roller gear part of centering, regulate according to 6 that the defect fixture of end face run-out is joined interior hexagonal flower shape fillister head screws 5, compensating approach is done to clamping deformation.The grinding of its teeth portion can be carried out after the clamping of roller gear part.Use and prove that this gear grinding clamp is reliable, and the quality of processed roller gear part can be ensured.
This fixture, in actual production, has given full play to its due effect according to the arrangement of roller gear part manufacturing procedure.In using, due to uniqueness design cleverly make gear part install and processing all very convenient.The embodiment that the utility model accompanying drawing describes is exemplary, only for explaining the utility model, and can not be interpreted as restriction of the present utility model.
