Background
The aluminum alloy wheel is manufactured according to the process flows of aluminum ingot smelting, blank casting, heat treatment, metal processing, spraying and the like. In the heat treatment process, the shape of the aluminum alloy wheel is changed due to various reasons such as the change of internal structure performance, the release of internal stress, the structure of the blank and the like, and the aluminum alloy wheel is generally called as blank deformation.
"blank deformation" is a very complicated process, and includes various situations such as roundness deformation, end surface deformation, radial deformation and the like in view of dimensional change. In fact, any deformation will affect the subsequent metal working to a greater or lesser extent, and will in turn affect the yield. Specifically, the roundness deformation may cause various defects such as "deviation", "insufficient machining amount", "balance waste", and the like. Therefore, the roundness correction device for the aluminum alloy wheel needs to be designed to solve the problem of roundness deformation of the blank of the aluminum alloy wheel.

In order to realize the purpose, the technical scheme of the utility model is that: a roundness correcting device for an aluminum alloy wheel comprises a clamping part and a correcting part. The clamping part consists of a clamp bottom plate, a shifting rod, a positioning mandrel, a pressure plate and a locking nut, wherein the shifting rod and the positioning mandrel are arranged on the clamp bottom plate, and the locking nut and the pressure plate are arranged on the positioning mandrel; the correcting part consists of a correcting roller, a pin shaft, a roller bracket, a needle bearing, an adjusting nut, a thrust bearing, a base, a push rod, a spring and a nut, wherein the needle bearing is arranged inside the correcting roller, the correcting roller is arranged on the roller bracket through the pin shaft, the push rod is arranged on the base, the head of the push rod is connected with the roller bracket, the spring and the nut are arranged at the bottom of the correcting roller and used for resetting, the adjusting nut and the thrust bearing are arranged in the middle of the push rod, the adjusting nut is rotated to drive the push rod to move up and down, and the roller bracket and the. The clamping part is arranged on a lathe spindle, and the correcting part is arranged on a lathe body.
Before roundness correction, a positioning mandrel and a deflector rod with corresponding sizes are selected according to the specification of the aluminum alloy wheel, the positioning mandrel plays a role in radial positioning, and the deflector rod is used for driving the wheel to rotate; the wheel end is then placed against the fixture base plate and tightened with a pressure plate and lock nut. At this time, the lathe can drive the wheel to rotate.
When the lathe works, the lathe is started firstly, and the lathe drives wheels to rotate through the clamp bottom plate and the deflector rod; then, rotating an adjusting nut, driving an ejector rod to move upwards by the adjusting nut, and driving a correcting roller to move upwards by the ejector rod through a roller bracket until the correcting roller is contacted with a wheel; and continuously rotating the adjusting nut under the condition that the wheel rotates, so that the correcting roller continuously generates radial extrusion force on the wheel, and when the radial extrusion force reaches the degree of generating plastic deformation on the wheel, the roundness of the aluminum alloy wheel can be recovered, so that the aim of correcting the roundness is fulfilled.
The radial extrusion force is continuously applied under the condition that the wheel rotates, so the force application direction is the whole circumferential direction of the wheel, the wheel is uniformly stressed, the plastic deformation consistency is good, the local plastic deformation is not overlarge, and the local internal damage of the wheel is not caused.
The utility model discloses can satisfy the needs that the aluminum alloy wheel circularity was rectified, can play the effect that improves the blank qualification rate, reduces the blank waste product, have simple structure, stable performance's characteristics simultaneously.
