Machine Bed Frame Cross Member Alignment Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for aligning components in machine assembly, such as engines or generators, are cumbersome and prone to mechanical failure due to imprecise alignment, particularly with components like cooling fans and radiators, which require precise height and angle adjustments without causing distortion to the side members.
Innovation Solution
A system featuring adjustable cross members with jacking members and a removable tool with jacking plates and screws allows for precise alignment and secure mounting of components by adjusting the height and angle of the cross members relative to the side frame members, preventing distortion and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If external jigs are used to carry and move components on cross members for alignment, then alignment capability is improved, but device complexity and ease of operation deteriorate due to cumbersome processes
Solution Approach 1:
The invention extracts the alignment function from external jigs and integrates it into the bed frame structure itself. The side members are designed with built-in adjustment mechanisms that allow cross members to be positioned and aligned directly on the frame without requiring separate external alignment tools or jigs.
Solution Approach 2:
The invention introduces an intermediary adjustment mechanism between the cross member and side member connection. This mechanism includes adjustable mounting brackets with threaded rods or similar adjustment devices that enable precise positioning of cross members relative to side members during assembly, facilitating alignment without external jigs.
2Manufacturing precision
If cross members are adjusted for height and angle before bolting, then alignment precision is improved, but ease of operation deteriorates due to cumbersome adjustment processes
Solution Approach 1:
The invention makes the mounting system dynamic by providing adjustable connections between cross members and side members. The adjustment mechanisms allow the cross members to be easily repositioned in height and angle during assembly, and once positioned correctly, can be securely fixed. This dynamic adjustment capability simplifies the alignment process compared to rigid pre-fixed connections.
3Manufacturing precision
If jacking members are used to adjust cross member position, then alignment precision is improved, but reliability deteriorates if side members distort during adjustment
Solution Approach 1:
The invention applies local quality by providing specific reinforcement or structural design features at the locations where jacking members contact the side members. The side members are designed with appropriate thickness, stiffness, and support structures at the adjustment points to withstand the localized forces applied during cross member positioning without causing distortion or compromising overall structural integrity.
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 precise alignment and secure mounting of machine components, enhancing cooling efficiency and preventing mechanical failure by allowing fine adjustments of the cross member's position and angle without distorting the side members, thus improving the assembly process efficiency and reducing costs.
Implementation Method 1
A threaded spindle passes through the bearing plate, and engages with an inner thread on the cross member. This allows the height of the cross member to be adjusted.
Implementation Method 2
The jacking member may be a threaded component such as a bolt or a screw, although any other type of jacking member such as a ratchet could be used instead.
