Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for machining bolt hole chamfers on wheel flanges are inefficient, particularly in automatic production settings, as they require lengthy single-hole machining, which does not meet the requirements for high-speed machining centers.
Innovation Solution
A chamfer removing device comprising a lower base, upper base, guide table cylinder, deceleration motor, supporting plate, external thread guiding sleeve, sliding box, drill bits, and internal thread guiding sleeve, which adjusts the wheel's position and uses air pressure and gear-driven drill bits to efficiently remove chamfers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If single hole chamfer removing method is used, then machining precision is maintained, but productivity is low
Solution Approach 1:
The device divides the wheel flange into multiple sections with multiple drill bits positioned at different locations. Each drill bit processes one bolt hole simultaneously, transforming the single-hole sequential machining into multi-hole parallel machining, thereby significantly improving productivity while maintaining precision through individual bit control
Solution Approach 2:
The device combines multiple chamfer removing operations into a single integrated processing step. Multiple drill bits are mounted on the same rotating mechanism and driven by a single motor, allowing simultaneous chamfer removal from multiple bolt holes that were previously processed sequentially, thus enhancing productivity without sacrificing precision
2Device complexity
If single hole chamfer removing method is used, then device complexity is low, but productivity is low
Solution Approach 1:
The device employs a universal processing mechanism that can handle multiple bolt holes with a single rotating assembly. The drill bits are positioned on a common mechanism that rotates to align with different bolt holes, allowing one mechanism to perform multiple chamfer removing operations that would otherwise require separate dedicated tools, thereby improving productivity without proportionally increasing device complexity
Solution Approach 2:
The device uses a dynamic rotating mechanism to position multiple drill bits at different angular locations. The rotation allows the same physical mechanism to access multiple bolt holes sequentially or simultaneously, transforming a static single-point tool into a multi-functional dynamic system that improves productivity while maintaining relatively simple device architecture

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device enables efficient, automatic chamfer removal for wheels of varying sizes and heights, significantly improving machining efficiency and adaptability.
Implementation Method 1
When air is introduced into the guide table cylinder, the connecting plate, the deceleration motor, the supporting plate and the sliding box move up in the axial direction
Implementation Method 2
air is introduced into the cylinders, the pressure blocks in threaded connection with cylinder rods motion linearly to compact the wheel lip
Implementation Method 3
The center shaft is connected with the output end of the deceleration motor via the key, the center shaft is driven to rotate via the bearing, each of the gears is fixed on the center shaft by using the shoulder and the key and rotates along with the center shaft
Implementation Method 4
an output rod of the guide table cylinder pushes the connecting plate, the deceleration motor, the supporting plate and the sliding box to move up in the axial direction and simultaneously drives the drill bits to implement an upward cutting action

AI summary
The present application provides a chamfer removing device for wheels. The device may be used for removing a bolt hole chamfer on flange side of back cavity of a wheel in hub machining process. Drill bits are spaced a certain height from the flange side of the wheel by adjusting the relative height of an external thread guiding sleeve in an internal thread guiding sleeve, a motor and gears drive the drill bits to rotate, and a cylinder and a sliding box drive the drill bits to move up and down so as to realize chamfer removing function.
