Slide Hammer Pliers With Threaded Clamping Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools, such as slide hammers and locking pliers, often struggle to effectively grip and remove components due to misalignment, cumbersome design, and inadequate gripping force, especially in tight or crowded spaces.
Innovation Solution
A slide hammer attachment with pliers featuring a threaded clamping mechanism that provides a co-axial, secure grip on fasteners or workpieces, allowing for forceful removal when used with a slide hammer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If conventional locking pliers are used with slide hammers, then gripping force can be applied, but the pliers cannot properly align the axis of the component with the axis of the slide hammer weight/shaft due to offset axis or non-parallel orientation
Solution Approach 1:
The tool is divided into separate functional segments: a slide hammer attachment portion for generating pulling force and a pliers portion for gripping. This segmentation allows each part to be optimized independently while working together, with the attachment portion providing co-axial alignment and the pliers providing gripping capability.
Solution Approach 2:
A threaded shaft acts as an intermediary mechanism between the slide hammer attachment and the pliers jaws. Rotating the threaded shaft creates differential movement that simultaneously tensions the pliers for gripping and maintains co-axial alignment with the slide hammer axis, resolving the alignment issue.
2Ease of operation
If conventional locking pliers are used, then components can be gripped, but the design is cumbersome and not well-suited for tight-fitting or crowded spaces
Solution Approach 1:
The pliers jaws and mechanism are nested within a compact attachment structure that integrates with the slide hammer. The threaded shaft mechanism allows the jaws to be positioned close together while maintaining the gripping function, reducing the overall footprint for tight spaces.
Solution Approach 2:
The pliers mechanism transitions from a static conventional design to a dynamic system where the threaded shaft rotation creates controlled movement and tensioning of the jaws. This dynamic mechanism allows for adjustable gripping force and compact configuration suitable for crowded spaces.
3Force
If traditional pullers are used, then components can be removed, but they cannot sufficiently grip and successfully remove components requiring large amounts of gripping and pulling force due to obstruction from adjacent equipment
Solution Approach 1:
The tool merges the functions of a slide hammer (for generating high pulling force) with a pliers mechanism (for secure gripping). This combination allows the application of substantial pulling force through the slide hammer while the pliers jaws provide secure grip on the component, enabling removal even when access is restricted by adjacent equipment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The attachment enables secure, co-axial clamping and effective removal of workpieces with improved gripping force and alignment, overcoming the limitations of traditional tools in tight spaces.
Implementation Method 1
The threaded mechanism may include a threaded shaft about which the jaws of the pliers may be coupled and tensioned to sufficiently grip the workpiece
Implementation Method 2
Upon impact with the stop, inertia from the mass is transferred to the shaft, generating an axial impacting-type force on the shaft in the direction the mass slid

AI summary
A slide hammer attachment with pliers-type or clamping members having a threaded clamping mechanism for securely gripping a fastener or work piece. The tool, when coupled to a slide hammer, may provide a secure clamping force, co-axial with an axis of a slide hammer shaft, on or about a fastener or work piece. The clamping force may facilitate removal of the work piece from a fitting with a pulling-type force.
