Modular Side-by-Side Vise With Positioning Lug Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional side-by-side vise structures require technicians to hold one piece while tightening or loosening bolts, making it difficult to apply force, and the adjustment of clamp distances based on graduations on the base is time-consuming and prone to dimensional tolerance issues.
Innovation Solution
A modular side-by-side vise structure with laterally extending grooves and fixture blocks featuring detents and positioning lugs, allowing for easy assembly and disassembly without manual holding and enabling quick adjustment of clamp distances using side clamping pieces that fix securely to the base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the side clamping piece is fixed to the base with a bolt, then the clamping force is improved, but the operator must hold the side clamping piece with one hand while tightening the bolt with the other hand, making it difficult to apply force
Solution Approach 1:
A positioning lug is introduced as an intermediary component that fits into a positioning groove on the base. This positioning groove acts as a mediator that automatically supports the side clamping piece during bolt tightening, eliminating the need for manual holding and allowing the operator to apply full force to the bolt.
2Manufacturing precision
If the clamp distance is adjusted according to graduations on the base before clamping, then the preset clamp distance is achieved, but this action takes time and leads to dimensional tolerance problems in workpiece manufacturing
Solution Approach 1:
The positioning groove is pre-configured at a fixed position on the base, establishing a predetermined clamp distance before the workpiece is even placed. This preliminary positioning action eliminates the need for time-consuming adjustments during operation, while the fixed groove geometry ensures precise dimensional tolerance for workpiece manufacturing.

AI summary
A modular side-by-side vise structure including a base, a fixture block group located on the base, and a side clamping piece group; the side clamping piece has an upper part and a lower part, and a bolt is screwed in the upper part to prop the lower part, so that the stopper and movable fixture block cling to the base tightly; or the side grooves on both sides of the stopper and movable fixture block are provided with bolt holes, and the inner wall of side clamping piece is provided with a punch hole, the bolt is screwed in the bolt hole through the punch hole, so that the stopper and movable fixture block cling to the base tightly. Therefore, it is unnecessary to hold up the side clamping piece with a hand while tightening or loosening the bolt, favorable for the technician to implement quick assembly or disassembly.
