Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hydraulic machining tongs require extensive maintenance, have limited precision in force and movement control, and occupy excessive space due to the hydraulic pressure cylinder, leading to potential collisions in cramped applications.
Innovation Solution
The use of electric drive units for both the actuating and infeed devices in machining tongs, with a power transmission mechanism to amplify the auxiliary machining force, allowing for precise control of machining movements and reducing overall height, enabling the use of lower output drive units with lower energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a hydraulic pressure cylinder is used for the actuating device, then high machining force can be generated, but the overall height increases and maintenance requirements increase
Solution Approach 1:
The patent replaces the hydraulic pressure cylinder with an electric drive unit (such as a servo motor or electric cylinder) to generate the machining force. This substitution eliminates the need for hydraulic fluid and associated components, reducing maintenance requirements while allowing for a more compact design with reduced overall height. The electric drive unit directly or indirectly drives the tool ram to deliver the required machining force.
Solution Approach 2:
The patent employs a power transmission mechanism (such as a toggle mechanism, linkage, or radial displacement system) that converts motion or force from one dimension to another. For example, a radially displacing power transmission element can convert axial motion into radial positioning, or use a toggle mechanism to amplify force while reducing the axial stroke required. This dimensional transformation allows achieving high machining force with a more compact overall height.

3Measurement precision
If separate drive units are used for actuating and infeed devices, then precise control is possible, but device complexity increases
Solution Approach 1:
The patent combines the actuating device and infeed device into a single integrated drive unit. This unified drive unit can perform both infeed movement (positioning the tool ram) and actuating movement (generating machining force) through different operational modes or stroke phases. By merging the two functions into one drive unit, the patent reduces the number of separate components while maintaining precise control through programmable motion sequences, thus lowering device complexity without sacrificing control precision.
4Length of moving object
If the tool ram is spaced axially from the pressure piston, then infeed movement is possible, but the overall height increases
Solution Approach 1:
The patent employs a power transmission mechanism (such as a toggle mechanism, linkage, or radial displacement system) that converts motion or force from one dimension to another. For example, a radially displacing power transmission element can convert axial motion into radial positioning, or use a toggle mechanism to amplify force while reducing the axial stroke required. This dimensional transformation allows achieving high machining force with a more compact overall height.
