Description
Technical field
The present invention relates to product processing technique field, and in particular to the processing of product bearing hole.
Background technology
Axle portion, such as Fig. 1 are fixed and installed to Motorcycle Aluminum Alloy wheel hub typically in assembling by the way of two side bearings
Shown, the bearing of both sides is respectively clutch shaft bearing 10 and second bearing 20, and drive shaft 30 coordinates with clutch shaft bearing, second bearing pacifies
Dress.
If the both sides bearing hole axiality on wheel hub 40 is excessive, it can cause after axle portion installation, wheel hub is tilted, and is directly affected
Stability and security of the motorcycle in ride, as shown in Figure 2.
At present, the general processing process of processing above-mentioned wheel hub both sides bearing hole is：Using the radial centre lines of wheel rim as
Two bearing holes are divided to two process completions, i.e. using wheel hub right flank as positioning datum by boundary, bearing hole on the left of processing wheel hub, then
Using wheel hub left surface as positioning datum, bearing hole on the right side of processing wheel hub.In the technical standard of product, the bounce deviation of wheel rim end face
Typically within 0.5mm, the coaxiality deviation requirement of two bearing holes must be in 0.05mm, as shown in Figure 3.
In the design and processes of wheel hub are formulated, the positioning datum of two sequences is usually using the bearing hole of a sequence as positioning base
Standard, because the positioning method of two sequences is gap positioning (bearing hole of a sequence coordinates with the gap of positioning core 80), according to bearing hole
Design tolerance and positioning core design tolerance, the gap between the bearing hole and positioning core of wheel hub is 0.05mm to the maximum,
Also, because auxiliary positioning face is wheel rim end face, the run-out tolerance that end face allows is 0.5mm to the maximum, as shown in Figure 4.
Gap between the bearing hole and positioning core of wheel hub, the run-out tolerance of wheel rim end face, it is above-mentioned that both influence each other,
Especially when wheel rim end face run-out is in higher limit, product can not obtain horizontal positioned in clamping plane, but draw (pressure)
Under power effect, product is forced to draw (pressure) to put down, because the end face existed after mechanically deform and processing post-tensioning (pressure) power disappearance is anti-
Bullet, axiality requirement is just difficult to be guaranteed, and depending on the difference of product tympanic part length dimension, maximum coaxiality deviation is possible to reach
To 0.1-0.2mm, as shown in Figure 5.
Understood by above-mentioned analysis, conventional technique obviously can not ensure the axiality requirement of wheel hub both sides bearing hole.
The content of the invention
Technical problem solved by the invention：How the axiality requirement of wheel hub both sides bearing hole is ensured.
In order to solve the above technical problems, the present invention provides following technical scheme：A kind of product axis hole two end axles bearing bore plus
In work technique, the product axis hole two ends, at least one end is provided with axial convex portion, center line and the product axis hole of the axial convex portion
Center line is overlapped；The axial convex portion is stretched into the positioning sleeve being fixedly installed and is positioned, and the first process tool is to remotely located set
One end of product axis hole carry out bearing hole machined, the second process tool stretches into product axis hole to the product axis hole close to positioning sleeve
The other end carry out bearing hole machined.
In above-mentioned technical proposal, grasping system acts on product, and product is acted on it by positioning sleeve and grasping system
Power, both are in opposite direction, and product is positioned.
By above-mentioned technical proposal, the first process tool carries out bearing hole machined, the second process tool to product axis hole one end
Stretch into product axis hole and bearing hole machined is carried out to the product axis hole other end, positioning sleeve is used for the positioning hole for positioning the axial convex portion
Condition is provided for the second process tool converted products axis hole other end bearing hole.In this way, the present invention is through primary production clamping, i.e.,
Can the bearing hole at product axis hole two ends completely processing, it is ensured that the axiality of axis hole two end axles bearing bore.
Processing technology described in above-mentioned technical proposal applies to adding for Motorcycle Aluminum Alloy hub centre hole both sides bearing hole
Work, i.e. the product is Motorcycle Aluminum Alloy wheel hub, the axis hole is the centre bore of Motorcycle Aluminum Alloy wheel hub.
The positioning sleeve is fixed in positioning pedestal, and positioning pedestal is provided with clamping plane, and the clamping plane is to wheel rim
End face is positioned.Grasping system acts on wheel hub, and wheel hub is pressed in the clamping plane and the positioning sleeve, to ensure wheel
The precision of hub positioning, improves the stability of wheel hub positioning.
Positioning sleeve is used for the positioning hole for positioning axial convex portion in cone, i.e., described positioning hole is in enlarging shape, the axial direction
Convex portion is rounded, and the positioning hole of enlarging shape is stretched into circular axial convex portion, is easy to positioning sleeve convex to the axial direction of external diameter different sizes
Portion is positioned.
The circumferential side wall of positioning sleeve and bottom are equipped with the chip-removal hole on chip-removal hole, circumferential side wall close to the bottom of positioning sleeve
Portion, the chip-removal hole is used to discharge metal fillings produced when the first process tool and the second process tool processing bearing hole, just
In processing of second process tool to bearing hole.
Second process tool is boring cutter or is referred to as drawing boring cutter, and the centre bore of wheel hub is opened in the tympanic part of wheel hub, drum
Portion head, the drawing boring cutter of corresponding size stretches into the center of wheel hub from the one end in the hub centre hole (product axis hole) of remotely located set
Hole, to the other end close to the hub centre hole of positioning sleeve, processes bearing hole.
The present invention is applicant by field test and groped, a set of production dedicated for ensuring axiality developed
Technique.A main sequence positioning tool and process tool by design specialized, the bearing hole work step processed originally by two sequences is moved
Move to sequence processing, the bearing hole of product axis hole both sides is machined in same process, eliminate position gap, wheel rim
Influence of the run-out tolerance to axiality, it is ensured that meet technical requirements.The positioning sleeve specially devises chip-removal hole, adds each work step
The aluminium skimmings produced during work, will not accumulate in heart hole, obstruction will not be produced to cutter and is interfered, makes drawing boring process in the product
Smoothly, accurately.
