Vice Reclamping Station with Pressure Plunger for Precise Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reclamping devices for workpieces between two vices rely on the accuracy of a robot, which limits the precision of workpiece positioning, especially when the second vice is held by the robot.
Innovation Solution
A reclamping device with a handling device for positioning and actuating two vices, and a reclamping station featuring a carrier for accurately holding a first vice and a pressure device with a movable pressure plunger to precisely press the workpiece against the vice, independent of the handling device's accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the robot holds the second vice during workpiece transfer, then the device complexity is reduced and automation is improved, but the manufacturing precision of workpiece positioning deteriorates
Solution Approach 1:
The patent introduces a pressure device as an intermediary component between the robot and the workpiece. This pressure device with pressure plunger provides a stable reference frame for workpiece positioning during transfer, decoupling the positioning accuracy from the robot's positioning accuracy. The pressure device acts as a mediator that ensures precise workpiece positioning even when the robot holds the vice.
2Device complexity
If the workpiece is held only by the vices during transfer, then the device complexity is reduced, but the reliability of workpiece holding deteriorates when vices are open
Solution Approach 1:
The patent combines two holding mechanisms: the vice clamping mechanism and the pressure device mechanism. The pressure device merges with the vice system to provide dual holding functionality - the vice holds the workpiece when closed, and the pressure device provides additional securing when vices are open during transfer, ensuring reliability throughout the entire process.
Solution Approach 2:
The pressure device serves as an intermediary holding mechanism that supplements the vice holding. When the vices are open during transfer, the pressure device mediates the holding function, ensuring the workpiece remains securely positioned without relying solely on the open vices.

AI summary
A reclamping device for reclamping a workpiece between two vices has a handling device for positioning and actuating the two vices and a reclamping station which contains a carrier for holding a first vice in an accurate position. The reclamping station contains a pressure device with a pressure plunger movable relative to the carrier by an actuator for pressing the workpiece against the first vice positioned on the carrier.
