Solution Overview
Problem
Conventional abrasive belt machines require extensive time and effort for adjustments due to the heavy and complex screwing fasteners, which hinder work efficiency during maintenance and belt replacements.
Innovation Solution
An adjusting device for lifting and lowering a workbench, featuring an adjusting wheel with a threaded hole, a screwing fastener with a bushing, and an elastic member, allowing for easy up and down movement of the workbench through screw rotation, reducing the need for manual adjustments and enhancing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional screwing fasteners are used to control tightness of the abrasive belt wheel set, then the machine structure is stable and reliable, but the adjustment time increases significantly and work efficiency decreases
Solution Approach 1:
The invention divides the adjustment mechanism into separate functional components: a quick-release lever mechanism for rapid adjustment and screwing fasteners for final locking. This segmentation allows the adjustment process to be divided into two stages - quick positioning using the lever and precise securing using the screws - thereby reducing overall adjustment time while maintaining structural reliability
Solution Approach 2:
The quick-release lever performs preliminary positioning of the abrasive belt wheel set before the final locking action. By pre-positioning the component close to its target location using the lever mechanism, the subsequent screwing operation only requires minor adjustments, significantly reducing the time and effort needed for final securing while ensuring reliable locking
2Reliability
If multiple screwing fasteners are used to lock the abrasive belt wheel set, then the locking reliability is improved, but the device complexity and operation difficulty increase
Solution Approach 1:
The invention combines multiple fastening functions into a single integrated mechanism where the quick-release lever and screwing fasteners work together as one system. The lever mechanism provides preliminary securing action while the screws provide final locking, merging the functions of multiple fasteners into a coordinated two-stage system that reduces operational complexity
Solution Approach 2:
The quick-release lever mechanism automatically performs the preliminary positioning and partial securing function, reducing the manual effort required for the screwing operation. The mechanism is designed so that the lever action itself contributes to the locking process, making the system partially self-servicing and reducing the complexity of manual operation
3Strength
If the abrasive belt wheel set is made heavy for durability, then the machine strength and stability are improved, but the ease of adjustment and work efficiency deteriorate
Solution Approach 1:
The invention introduces a dynamic adjustment mechanism using the quick-release lever that allows for rapid movement and repositioning of the abrasive belt wheel set. This dynamic component enables easy adjustment despite the heavy weight of the wheel set, as the lever mechanism provides mechanical advantage to overcome the weight during adjustment operations while maintaining stability during normal operation
Applied Scientific Principles
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 significantly shortens the time required for machine corrections and adjustments, improving work efficiency by enabling easy movement and positioning of the workbench without affecting the processing of work pieces.
Implementation Method 1
An elastic member is fitted around the outer circumference of the bushing and positioned between the flange of the screwing fastener and the topside of the fixed plate, and further the elastic member has a prestress toward the workbench
Implementation Method 2
An adjusting seat is firmly fixed with the workbench rest and bored with a longitudinal threaded hole. An adjusting wheel has one end screwed with the threaded hole of the adjusting seat

AI summary
An adjusting device for lifting and lowering a workbench is provided between a workbench and a workbench rest. An adjusting seat is firmly secured with the workbench rest and an adjusting wheel is screwed and locked on the adjusting seat. A screwing fastener is inserted through the underside of the workbench and the adjusting wheel, and an elastic member is provided between an upper flange of the screwing fastener and the topside of a fixed plate of the workbench. Thus, by the prestress of the elastic member pushing against the workbench, the workbench can be surely driven by screw rotation of the adjusting wheel and hence the adjusting wheel can easily drive the workbench to move up and down.
