Deburring Machine Spindle Rotation Direction and Thrust Force Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deburring machines for wood, metal, and plastic materials face issues with precision due to concordant thrust forces from adjacent tool-holder spindles, leading to movement of elements and non-uniform deburring operations, especially at the front and rear ends.
Innovation Solution
A deburring machine design where tool-holder spindles rotate in the same direction, utilizing a belt transmission system with toothed and idler pulleys to balance thrust forces and ensure uniform deburring, featuring a gantry frame with oscillatory motion and aligned rotation axes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If tool-holder spindles rotate in opposite directions, then the drive belt can be wound in a zigzag shape around the toothed pulleys, but concordant thrust forces cause element movement and reduce deburring precision
Solution Approach 1:
The patent inverts the conventional rotation direction arrangement by making all tool-holder spindles rotate in the same direction rather than alternating directions. This inversion eliminates the concordant thrust forces that cause element movement, thereby resolving the technical contradiction between ease of operation and manufacturing precision.
2Device complexity
If tool-holder spindles rotate in opposite directions, then the drive belt structure is simplified, but the uniformity of deburring operations on front and rear ends is compromised
Solution Approach 1:
The patent applies homogeneity by making all tool-holder spindles rotate in the same direction, creating uniform deburring forces across the entire element surface. This ensures consistent deburring quality on both front and rear ends, resolving the contradiction between device complexity and manufacturing precision.
3Manufacturing precision
If tool-holder spindles rotate in the same direction, then thrust forces are balanced and element stability is improved, but the drive belt cannot be wound in a zigzag shape
Solution Approach 1:
The patent extracts the zigzag configuration requirement from the drive belt system, replacing it with a simpler linear or alternative routing that accommodates the same-direction rotation of all spindles. This extraction allows the system to achieve element stability without being constrained by the zigzag belt winding.

AI summary
In a deburring machine for the finishing of elements (2) made of wood, metal, plastic material or the like, each element (2) is fed through a deburring assembly (9), which is mounted crosswise to a feeding direction (4) of the element (2) and is provided with a plurality of tool-holder spindles (15), each designed to receive and hold a respective finishing tool and mounted so as to rotate in a rotation direction that is the same as a rotation direction of the other tool-holder spindles (15).
