Abstract
The utility model discloses a kind of high accuracy wheel hub processing technique equipment, comprise workbench, clamps, wheel hub blank, machine tool, described clamps is that the arc fixture block of two pieces or more forms wheel cuff-like fixture, the cylindrical of described wheel hub blank is installed in the inner surface of wheel cuff-like fixture, settles described machine tool at the machined surface of the other corresponding wheel hub to be processed of wheel cuff-like fixture.The utility model, by process modification such as wheel hub blank, process tool, cutting parameters, improves Product Precision and uniformity, reduces percent defective, improve high accuracy wheel hub working (machining) efficiency.
Description
Technical field
The utility model relates to auto parts and components process equipment technical field, and more particularly, it relates to a kind of high accuracy wheel hub processing technique equipment.
Background technology
For the axletree of some high-precision requirement, the adjustment-free gap axis of such as Guangdong Fuhua company, require to control wheel hub dead eye diameter and spacing dimension PPK≤1.33(initial procedure Capability index), adopt common process method can not reach the requirement of this high accuracy wheel hub, therefore, need by process modification such as wheel hub blank, process tool, cutting parameters, Product Precision and uniformity could be improved.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of high accuracy wheel hub processing technique equipment, improves Product Precision and efficiency, saves processing cost.
The technical scheme in the invention for solving the technical problem is: high accuracy wheel hub processing technique equipment, comprise workbench, clamps, wheel hub blank, machine tool, described clamps is that the arc fixture block of two pieces or more forms wheel cuff-like fixture, the cylindrical of described wheel hub blank is installed in the inner surface of wheel cuff-like fixture, settles described machine tool at the machined surface of the other corresponding wheel hub to be processed of wheel cuff-like fixture.
Described machine tool adopts 55 o angle rhombus mechanical clamped cutting blades or 80 o angle rhombus mechanical clamped cutting blades.
Described wheel hub blank needs through artificial or natural aging treatment before machined.
Described cuff-like fixture of taking turns comprises three pieces of arc fixture blocks.
The beneficial effects of the utility model are:
1. the utility model is by process modification such as wheel hub blank, process tool, cutting parameters, improves Product Precision and uniformity, reduces percent defective, improve high accuracy wheel hub working (machining) efficiency.
2. can complete the machinings such as the turning of the mating surface of the bearing position of wheel hub, wheel hub and brake drum in clamped one time, not only increase the uniformity that efficiency also assures that locating and machining benchmark, thus processing precision of products is improved.
3. empirical tests: processing adjustment-free gap axis high accuracy wheel hub, its dead eye diameter and spacing dimension PPK≤1.33.Axial gap brings up to 0.15mm by the 0.38mm of common axletree, decreases the swing of vehicle tire in the process of walking, ensures the stability of vehicle.
Accompanying drawing explanation
Fig. 1 is high accuracy wheel hub processing technique equipment structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, high accuracy wheel hub processing technique equipment of the present utility model, comprise workbench 3, clamps 2, wheel hub blank 1, machine tool (not shown), described clamps 2 is that three pieces of arc fixture blocks form wheel cuff-like fixture, the cylindrical of wheel hub blank 1 is installed in the inner surface of wheel cuff-like fixture, settles described machine tool (not shown) at the machined surface of the other corresponding wheel hub to be processed of wheel cuff-like fixture.Because the part profile of wheel hub is periphery, adopt wheel cuff-like fixture to form good circumferential profile, be conducive to the high accuracy processing of product.
In order to reduce the resistance to cutting of cutter in process, adopt 55 o angle D type blades (55 o angle rhombus mechanical clamped cutting blade), select suitable cutting parameter, and with being with 80 o angle C type blade (80o angle rhombus mechanical clamped cutting blade) finish turning bearing positions of wiper edges, to meet product requirement.
The wheel hub blank material that the utility model is selected is magnesium iron QT450-10, stable size is kept after making the turning of high accuracy wheel hub, the internal stress of blank must be reduced, in technique, therefore have employed method that is artificial or natrual ageing, reduce the workpiece deformation that the internal stress due to blank causes.Simultaneously, owing to using process equipment of the present utility model, process for machining is greatly improved: machined in clamped one time by the mating surface of the bearing position of wheel hub, wheel hub and brake drum, and by controlling the proportioning of cutting fluid, reducing heat in metal cutting causes internal stress to change, quality control reaches CPK≤1.33(Measure of Process Capability), ensure that high accuracy wheel hub Geometrical Tolerance Principle.In application cutter, by 55 o angle D type blades, the cutting parameter that configuration selection is suitable, and with being with 80 o angle C type blade finish turning bearing positions of wiper edges, improve machining accuracy.By adopting above-mentioned process means, make adjustment-free gap axis high accuracy wheel hub, its dead eye diameter and spacing dimension PPK≤1.33.Axial gap brings up to 0.15mm by the 0.38mm of common axletree.Substantially increase Product Precision.
The foregoing is only preferred embodiment of the present utility model; and be not used in restriction of the present utility model; all do within spirit of the present utility model and principle any amendment, the equivalent improvement etc. of replacing and doing without creative work, all should be included within protection domain of the present utility model.
