Counterweight Mechanism for Swivel Arrangement Vibration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional swivel arrangements in machining tools increase motor load, wear transmission mechanisms, and reduce the quality of products due to unreliable operation and shortened component lifespan.
Innovation Solution
A counterweight mechanism with two counterweights, each comprising a seat, an axle, and two cylinders, where the cylinders are pivotably secured to the axle and seat, allowing for reduced vibration and jarring through hydraulic or pneumatic action, eliminating the need for a speed reduction mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a motor is used to provide rotational force and stopping force to the swivel arrangement, then the swivel arrangement can be operated and positioned, but the motor load increases greatly and transmission mechanism wear increases
Solution Approach 1:
The patent introduces counterweights that balance the swivel arrangement's weight, allowing gravity to assist in supporting and positioning the swivel arrangement. This eliminates the need for the motor to continuously counteract gravity, significantly reducing motor load and transmission wear while maintaining operational capability.
Solution Approach 2:
The patent replaces the motor-driven mechanical stopping system with a gravity-based mechanical stopping mechanism. The counterweights create a natural stopping point when the swivel arrangement reaches a horizontal position, eliminating the need for motor braking and reducing mechanical wear.
2Ease of operation
If a motor is used to provide rotational force and stopping force to the swivel arrangement, then the swivel arrangement can be operated and positioned, but transmission mechanism wear increases and component lifespan decreases
Solution Approach 1:
The counterweights reduce the operational burden on transmission components by balancing the swivel arrangement's weight. This leads to reduced wear, lower operating temperatures, and extended component lifespan, directly improving system reliability.
Solution Approach 2:
By replacing motor-driven stopping with gravity-based stopping, the patent eliminates high-stress braking operations that cause transmission wear and component failure, thereby extending system reliability.
3Ease of operation
If conventional swivel arrangement operation is used, then the motor can control positioning, but product quality decreases due to unreliable operation
Solution Approach 1:
The counterweights provide stable, predictable positioning behavior by utilizing gravity to naturally settle the swivel arrangement at desired positions. This eliminates motor control inconsistencies and positioning errors, leading to more reliable operation and improved manufacturing precision.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution decreases vibration and jarring, increases the lifespan of machine components, and enhances the quality of products made by machining tools by distributing the rotational force effectively without excessive wear on the motor and transmission.
Implementation Method 1
Each of the cylinders have a first end pivotably secured to a position proximate to the axle and a second end pivotably secured to the seat. The cylinders are either hydraulic cylinders or pneumatic cylinders.
