Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the wheel blank is positioned by the process wheel lip without trimming, then the manufacturing process is simple, but the positioning accuracy deteriorates due to blank deformation causing uneven positioning end surface
Solution Approach 1:
The patent applies preliminary action by trimming the positioning end surface of the wheel blank before the machining process. The trimming device removes deformation and unevenness from the casting blank's positioning end surface in advance, ensuring that when the wheel blank is subsequently positioned by the process wheel lip, the positioning accuracy is maintained. This preliminary trimming action prevents positioning errors before they occur during machining.
Solution Approach 2:
The patent introduces an intermediary trimming device between the casting process and the machining process. This trimming device acts as a mediator that corrects the positioning end surface of the wheel blank, transforming the deformed surface into a uniform surface that can be accurately positioned by the process wheel lip during subsequent machining operations.
2Productivity
If traditional positioning method is used without trimming, then the device complexity is low, but productivity deteriorates due to turning deviation waste products
Solution Approach 1:
By performing preliminary trimming of the positioning end surface before machining, the patent eliminates turning deviation waste products that would otherwise occur during the machining process. This preliminary action ensures that the wheel blank is properly prepared, reducing material waste and improving manufacturing efficiency by avoiding rework or scrap.
Solution Approach 2:
The patent converts the harmful effect of blank deformation into a beneficial outcome by using the trimming device to remove the deformation. What would normally be a defect causing waste and reduced productivity is transformed into an opportunity to improve manufacturing efficiency through controlled preliminary processing that eliminates subsequent problems.
3Loss of substance
If the positioning end surface is not trimmed, then the ease of manufacture is high, but the loss of substance increases due to turning deviation waste
Solution Approach 1:
The trimming device performs preliminary removal of material from the positioning end surface to eliminate deformation and unevenness. This preliminary action reduces material waste during subsequent machining by ensuring that only necessary material is removed, rather than wasting material to compensate for positioning errors caused by an untrimmed surface.

AI summary
The present application discloses a device for trimming the positioning end surface of a wheel blank comprises a wheel positioning clamping system, an axial positioning surface trimming system and a radial positioning surface trimming system. The wheel positioning clamping system completes the loading, clamping and low-speed rotation of the wheel; the axial positioning surface trimming system firstly completes the detection of the wheel axial hop, and then completes the trimming of the axially positioning surface; the radial positioning surface trimming system firstly completes the detection of the wheel radial hop, and then completes the trimming of the radial positioning surface. The axially positioning surface trimming system and the radial positioning surface trimming system are independent of each other and complementary to each other, and the two systems accomplish the trimming of the positioning end surface of the wheel blank jointly.
