Rail Cover Attachment Jig Using Pressing Rollers Around Moving Blocks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for attaching a rail cover to a track rail in a motion guide device require the removal and re-mounting of the moving block, making the process cumbersome and potentially causing flaws or defects in the motion guide device.
Innovation Solution
An attachment assisting jig for a rail cover that allows for easy attachment without removing the moving block from the track rail, featuring a jig main body with operating grip and pressing rollers that adjust the distance between the rail cover's side wall portions, enabling them to be elastically spread and attached to the track rail.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rail cover is mounted to the track rail after removing the moving block, then the rail cover can be attached to cover the bolt mounting hole, but the process becomes cumbersome and may cause flaws or defects due to removal and re-mounting of the moving block
Solution Approach 1:
The patent introduces a jig as an intermediary tool that enables the rail cover to be attached without removing the moving block. The jig includes pressing members that apply force to spread the side wall portions of the rail cover, allowing it to be fitted over the track rail while the moving block remains in place. This mediator tool resolves the conflict between maintaining device integrity and simplifying the attachment process.
2Ease of manufacture
If the side wall portions of the rail cover are forcibly spread to attach to the track rail, then the rail cover can be mounted, but the moving block must be removed first making the process cumbersome
Solution Approach 1:
The patent employs preliminary action by pre-spreading the side wall portions of the rail cover using pressing members in the jig before final attachment. This pre-preparation allows the rail cover to be easily fitted onto the track rail without requiring removal of the moving block, thus saving time and simplifying the manufacturing process.
3Reliability
If the moving block is removed and re-mounted after attaching the rail cover, then the rail cover can be properly installed, but potential flaws or defects may be caused in the motion guide device
Solution Approach 1:
The jig serves as an intermediary device that enables the rail cover attachment process to proceed without disrupting the moving block. By providing a mechanism to spread and fit the rail cover in place, the jig eliminates the need for repeated removal and re-mounting of the moving block, thereby reducing assembly steps and maintaining device quality.
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
Enables the attachment of the rail cover to the track rail without removing the moving block, eliminating the cumbersome process and preventing potential defects, while ensuring smooth movement of the moving block and preventing interference with the rail cover.
Implementation Method 1
a pair of pressing rollers, which are arranged on a bottom surface of the jig main body so that peripheral surfaces of the pair of pressing rollers are brought into abutment against inner side surfaces of the pair of side wall portions, respectively, and are rotated in directions opposite to each other, and are configured to press the pair of side wall portions outward along with movement of the jig main body in the longitudinal direction of the rail cover
Implementation Method 2
a pair of side wall portions, which are provided at both ends of the flat surface portion in a short-side direction thereof, respectively, and are configured to elastically hold side surfaces of the track rail, respectively
