Segmented Grinding Pad Alignment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing belt grinder systems face challenges in maintaining effective alignment between segmented sanding pads and feeler elements at varying angles of inclination, particularly as the angle increases, leading to misalignment of segments with perpendicular feeler elements.
Innovation Solution
The use of a fixed stop, sliding segments, a guide axis, and a counter-pressure device, or alternative motor, electronic, or pneumatic devices to laterally shift segments and maintain alignment with feeler elements, allowing multiple segment sanding pads to operate at different positions while compensating for increased angle deviations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a segmented sanding pad is tilted at a larger angle, then the ability to handle complex surface geometries is improved, but the alignment between segments and feeler elements deteriorates
Solution Approach 1:
The patent applies the dynamics principle by making the sanding pad segments laterally displaceable relative to the feeler elements. The segments are mounted on laterally displaceable carriers that can move in the lateral direction, allowing the segments to dynamically adjust their position to maintain alignment with the feeler elements even when the pad is tilted at larger angles. This dynamic adjustment capability resolves the contradiction by enabling both large tilt angles for complex surfaces and precise alignment for measurement accuracy.
2Manufacturing precision
If a lever device is used to laterally displace segments, then alignment compensation is improved, but device complexity increases
Solution Approach 1:
The patent applies the mechanics substitution principle by replacing the traditional lever device with a motor-driven lateral displacement mechanism. Instead of using mechanical levers to displace the segments laterally, the invention uses motors (electric or pneumatic) to drive the lateral movement of segments on their carriers. This substitution reduces mechanical complexity while maintaining or improving the precision of alignment compensation, as motorized control offers more precise and controllable displacement.
3Manufacturing precision
If feeler elements are repositioned laterally to match tilted segments, then alignment is improved, but the fixed row of feeler elements can only serve a single inclination angle
Solution Approach 1:
The patent applies the inversion principle by reversing which component moves laterally. Instead of moving the feeler elements laterally to match the tilted segments (as in prior art), the invention moves the segments laterally on their carriers to maintain alignment with the fixed feeler elements. This inversion allows the fixed feeler element row to serve multiple inclination angles, as the segments can be laterally repositioned to compensate for different tilt angles while the feeler elements remain in their original positions.

AI summary
When a segmented grinding pad (11, 12, 13) of a continuous belt grinding machine is inclined, the modified position of the row (15) of key elements in relation to the original, for example, right-angled position of the row (11) of segments presents a problem. The aim of the invention is to carry out an approximate comparison of the deviations created by the lateral displacement of the segments S1 ... Sn by means of a lever device (16) or a servomotor. The full compensation of the deviations of the segments from the longitudinal axis thereof to the key elements can be achieved by a special embodiment of one such device.
