Chamfering Depth Adjustment with One-Touch Pin Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beveling machines face challenges in accurately and quickly controlling the depth of bevel cut, leading to low precision and increased operational time, with risks of operator injury and cumbersome designs.
Innovation Solution
A one-touch bevel cut depth controller with a calibrated setting mechanism using location setting pins and a spring housing to automatically lock and maintain the bevel cut depth, allowing for safe and immediate control of the bevel cut depth during operation, regardless of cutter rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a rack is used to adjust the depth of bevel cut by operator's arbitrary setting, then the depth can be adjusted, but the accuracy is low and it takes a long time to control the depth
Solution Approach 1:
The depth controlling unit is divided into multiple positioning holes arranged at different depths, allowing the operator to select pre-defined depth positions rather than adjusting continuously, which improves accuracy and reduces adjustment time
Solution Approach 2:
The positioning holes are pre-configured at specific depth intervals, so the operator only needs to select from predetermined accurate positions rather than manually adjusting to achieve precise depth control
2Reliability
If a special locking control unit is tightened to prevent the bevel setting from being loosened, then the setting is secured, but the inconvenience in using the beveling machine increases
Solution Approach 1:
The depth controlling unit can be easily inserted and removed from the cutter shaft, transforming from a static fixed connection to a dynamic removable connection, which maintains setting stability during operation while improving ease of adjustment and removal
Solution Approach 2:
The depth controlling unit is designed to be separable from the cutter shaft, allowing the operator to remove it easily for adjustment or replacement without tightening locking mechanisms, thus improving convenience while maintaining reliability during cutting
3Ease of operation
If the bevel cut depth controlling unit is pulled downwardly toward the cutter to control the depth, then the depth can be controlled, but the operator's hand may be injured if contact with the cutter occurs
Solution Approach 1:
Instead of pulling the depth controlling unit downward toward the cutter, the unit is pulled upward away from the cutter to control depth, which maintains operational ease while eliminating the risk of hand injury from cutter contact
4Reliability
If an adapter with a special fixed spline is used to maintain the setting condition, then the setting is maintained, but it is difficult to manufacture and the size is cumbersome
Solution Approach 1:
The depth controlling unit uses a universal spline structure that can be manufactured with standard processes, eliminating the need for special fixed splines and complex adapters, thus improving manufacturability while maintaining setting reliability through the positioning hole mechanism

AI summary
The present invention relates to a one-touch chamfering-amount adjustment device for a chamfering machine which specifically carries out a chamfering process on the welding bead surfaces of objects to be processed (such as metal sheet materials and pipes). In the present invention, the moment after a chamfering-amount-adjustment piece has been manipulated so as to rotate, a position-setting pin is inserted into a securing recess in the chamfering-amount-adjustment piece and as this happens the chamfering amount is precisely adjusted in units and at the same time locking to the predetermined chamfering amount is automatically maintained, yet nevertheless the adjustment of the chamfering amount is achieved in a straightforward fashion with one touch, and, when the chamfering-amount-adjustment piece is manipulated, a cutter shaft moves vertically and as it does so the chamfering amount is adjusted in such a way that the chamfering amount can be immediately and rapidly adjusted even during working regardless of any cutter rotating action.
