Machine Vice Jawplate Quick Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional machine vice units require multiple turns of screws or screw bolts for locking and unlocking jawplates, which is time-consuming and fatiguing for machinists.
Innovation Solution
A modified machine vice jaw unit with vertically inclined countersunk continuous hole spaces in the mounting blocks and jawplates, featuring a plate-bolt-nut complex that allows for quick locking and unlocking with only a half turn of the screw bolt, enabling rapid and dependable attachment and detachment of jawplates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional screws or screw bolts are used for locking and unlocking jawplates, then reliable locking is achieved, but the process is time-consuming and requires multiple turns
Solution Approach 1:
The hole space is segmented into three distinct portions: a frontal rectangular portion, a mid cylindrical portion, and a rear rectangular portion. This segmentation allows the bolt to be inserted at an angle and provides different functional zones that enable quick locking with minimal rotation
Solution Approach 2:
The invention introduces angular/倾斜 dimensions to the hole space configuration, with the frontal and rear portions inclined relative to each other. This angular arrangement allows the bolt to be inserted at an angle and locked quickly without requiring multiple turns, transforming the conventional linear insertion approach
2Reliability
If multiple turns of screws are required for locking, then secure attachment is achieved, but operator fatigue increases
Solution Approach 1:
The threaded portion of the bolt is pre-configured with appropriate thread pitch and engagement length to achieve secure locking with minimal rotation. The hole space geometry is pre-designed to guide the bolt into the correct position, eliminating the need for multiple turns and reducing operator effort
3Strength
If conventional locking mechanisms are used, then jawplates are securely attached, but the process lacks efficiency
Solution Approach 1:
The invention changes the geometric parameters of the hole space, including the angular inclination between frontal and rear portions, the cylindrical mid-portion diameter, and the threaded bolt dimensions. These parameter optimizations enable secure attachment with minimal rotation, significantly improving changeover efficiency while maintaining attachment strength

AI summary
A machine vice quick locking system being a machine vice unit with modified mounting blocks, each having a plurality of vertically inclined continuous hole spaces with the mid-space portion of each hole space being amenable to receipt of the nut portions of a plate-bolt-nut complex unit serving to quickly facilitate a locking fast of either one and ultimately both of a pair of equivalently sized jawplates to either of the anterior or posterior walls of either modified mounting block portion of the machine vice unit with each jawplate featuring a pair of horizontally inclined counterbored holes for receipt by each, of one bolt portion of each complex unit.
