Impact Tool Dust Collection Device Two-Point Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dust collecting devices for impact tools have reduced stability and efficiency due to their mounting configuration, which increases the distance from the hood holding part to the front end, affecting the collection of dust generated during operations.
Innovation Solution
A dust collecting device is designed to be attached to the impact tool at two points, with the dust collecting part held on the tool bit and the transfer part on the tool body, allowing for closer placement to the dust generation area and adjustable positioning to improve stability and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the dust collecting device uses a cylindrical hood extending from the hood holding part on the tool body, then the dust collection function is provided, but the distance from the hood holding part to the front end of the hood is increased, reducing the stability of the dust collecting device
Solution Approach 1:
The dust collecting device is divided into two separate mounting locations: the dust collecting part is mounted on the shank of the tool bit, while the dust transfer part is mounted on the tool body. This segmentation allows the dust collecting part to be positioned close to the dust generation area for effective collection, while the dust transfer part provides stable mounting on the tool body, thus resolving the contradiction between providing dust collection function and maintaining device stability.
2Productivity
If the dust collecting part is placed closer to the dust generation area, then the dust collecting efficiency is improved, but the mounting stability is reduced
Solution Approach 1:
The device is segmented into a dust collecting part mounted on the tool bit shank (close to dust generation area for high efficiency) and a dust transfer part mounted on the tool body (providing stable mounting). This segmentation enables both high dust collection efficiency and mounting stability to be achieved simultaneously.
Solution Approach 2:
The dust transfer part acts as an intermediary component that connects the dust collecting part to the dust collection system. It is held on the tool body and receives dust from the dust collecting part, allowing the dust collecting part to be positioned optimally near the dust generation area while maintaining overall system stability through the intermediary connection.
3Stability of the object's composition
If the dust collecting device is held at two points (tool body and tool bit), then the mounting condition is improved, but the device complexity increases
Solution Approach 1:
The dust collecting part utilizes the existing shank of the tool bit for mounting, and the dust transfer part utilizes the tool body for mounting. Both components leverage already-present structural elements, allowing the device to achieve stable two-point mounting without adding complex mounting mechanisms or structures.
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 improved mounting configuration enhances the stability and efficiency of dust collection, allowing for effective dust trapping and extended device life without interfering with the tool's operation, while accommodating various tool bit lengths and diameters.
Implementation Method 1
The dust collecting part has a sliding part which is engaged at least in part with the shank of the tool bit and can move in the axial direction with respect to the shank. Accordingly, the dust collecting part is movably guided with respect to the shank of the tool bit via the sliding part

AI summary
Disclosed is a feature that contributes to an improvement in the attachment to an impact tool of a dust collection device that is attached to the impact tool and that collects dust particles that said impact tool generates. The dust collection device (140) collects dust that the impact tool (101) generates and is attached to said impact tool (101) that, in the lengthwise direction, linearly operates a tool bit (119) that is mounted to the tip region of a tool body (103). The dust collection device (140) has a dust collection unit (141, 143) that has a dust intake port (141a) at the tip; and a dust transfer unit (146) that is connected with the dust collection unit (141, 143) in order to transfer dust sucked in from the dust intake port (141a) towards the downstream side. The dust collection unit (141, 143) is held by the shaft section (119b) of the tool bit (119), and the dust transfer unit (146) is held by the tool body (103).
