Nail Stop Block Structure for Pneumatic Nailer Jamming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pneumatic coil nailers lack a restraining structure for the nail stop block, leading to nail jamming and blank shots due to the second nail deviating from the designed path when the nail feeding claw returns.
Innovation Solution
A novel nail stop block structure with a spring-actuated mechanism that keeps the second nail in the designed path, using a restraining groove formed by the nail stop block and the nail feeding claw, ensuring the second nail remains aligned and prevents deviation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional nail feeding mechanism is used without a restraining structure, then the structure is simple, but the second nail deviates from the designed path causing nail jamming and blank shots
Solution Approach 1:
The nail stop block is divided into multiple functional parts: a body portion with a restraining groove, a pressing portion with a pressing groove, and a guiding portion. Each segment performs a specific function in controlling nail movement, ensuring reliable nail feeding while maintaining reasonable structural complexity
Solution Approach 2:
The nail stop block acts as an intermediary component between the nail magazine and the nail feeding claw. It mediates the movement of nails by providing restraining grooves and pressing grooves that guide nails along the designed path, preventing deviation and ensuring reliable feeding
2Manufacturing precision
If the nail stop block has no restraining structure, then the structure is simple, but the second nail cannot be restrained leading to deviation from design path
Solution Approach 1:
The nail stop block features local quality variations through differently shaped grooves: a restraining groove with specific curvature for the first nail, and a pressing groove with different geometry for the second nail. Each groove is locally optimized to control the position and movement of specific nails with high precision
Solution Approach 2:
The nail stop block performs preliminary action by pre-positioning the second nail in the restraining groove before the nail feeding claw returns. This preliminary positioning ensures that when the claw returns to feed the next nail, the second nail is already in the correct position and will not deviate from the design path

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 novel nail stop block structure effectively prevents nail jamming by maintaining the second nail's position stability, allowing for continuous and accurate nailing without blank shots by ensuring the second nail enters the striker hole smoothly after the first nail is struck out.
Implementation Method 1
a spring arranged between the nail stop block and the bottom of the mounting slot
Implementation Method 2
The pneumatic coil nailer is a pneumatic tool, generally used for connecting the fences

AI summary
A novel nail stop block structure for nail stop and restraining comprises a nail head and a striker hole disposed in the nail head. The front orifice of striker hole is located in the front end face of nail head. A nail head cylinder is disposed on the left lower end of middle part of the nail head. A mobile hole is disposed in the center of upper surface of the nail head cylinder connected to the inner space thereof. An assorted nail feeding piston is disposed in the nail head cylinder. A piston rod coaxial with the mobile hole is disposed on the center of upper surface of the nail feeding piston. The upper end of the piston rod passes upwards through the mobile hole.
