Torque Socket with Visual Indication for Precise Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional torque sockets fail to accurately display the torque value during the screw locking process, leading to potential over-tightening and idle rotation issues due to the disengagement of the tool driving cylinder and passive seat, which compromises the precision of torque adjustment.
Innovation Solution
A torque socket with a torque value indication system, featuring a main body with an accommodation slot, a torque adjusting assembly including a spring and shaft cylinder, and an end cover ring, where the guiding tenon displaces along the arc-shaped guiding slot to compress the spring, allowing the indication mark to align with torque value marks on the indication ring, thereby displaying the locking torque value accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a torque socket with torque adjusting mechanism is used, then torque value can be adjusted, but the real torque value cannot be truly displayed when torque exceeds preset value
Solution Approach 1:
The patent implements a feedback mechanism through the indication ring with torque value marks and indication mark. As the shaft cylinder compresses the spring during torque application, the indication mark moves along the indication ring to display the current torque value, providing real-time feedback to the user about the actual torque being applied.
Solution Approach 2:
The patent introduces an intermediary indication system consisting of the indication ring, torque value marks, and indication mark. This intermediary mechanism translates the mechanical compression of the spring into visible torque value display, solving the problem of inaccurate torque indication when exceeding preset values.
2Reliability
If the tool driving cylinder and passive seat disengage to prevent over-tightening, then torque limit is protected, but idle rotation occurs and precise torque display is lost
Solution Approach 1:
The indication system provides continuous feedback during the torque application process, allowing users to monitor torque values in real-time. This enables operators to stop rotation at the precise moment when the desired torque is achieved, preventing both over-tightening and idle rotation.
Solution Approach 2:
The torque socket provides self-service through the automatic indication mechanism. As torque is applied, the indication mark automatically moves to reflect the current torque value without requiring additional input or observation from the operator, enabling precise control.
3Device complexity
If no torque indication system is provided, then the structure is simpler, but timely display of torque value during locking process cannot be achieved
Solution Approach 1:
The indication ring with torque value marks is pre-calibrated and positioned on the shaft cylinder before use. This preliminary setup allows the indication mark to immediately display the correct torque value as torque is applied, eliminating the need for separate measurement or calculation steps.
Solution Approach 2:
The torque indication system is self-activating and requires no external power source or additional操作步骤. As torque is applied to the fastener, the spring compression automatically moves the indication mark to display the current torque value, providing timely information without adding operational complexity.
