Hanger Mounting Plate Height Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for adjusting hanger arms in vehicle body production are inefficient due to spatial restrictions, time consumption, and limitations in compatibility, particularly when handling vehicles of varying shapes, leading to reduced productivity.
Innovation Solution
A system for automatically adjusting the height of a hanger mounting plate using a coupling pin mechanism, hanger arm fixing devices, a pin fixing device, and a mounting plate height adjusting device, which allows for precise alignment and adjustment of hanger arms based on vehicle body types, incorporating sensors for detection and positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual adjustment of hanger arm height is used to accommodate various vehicle body types, then adaptability is improved, but productivity deteriorates due to time-consuming manual intervention
Solution Approach 1:
The hanger arm height adjustment system transitions from static manual adjustment to dynamic automated adjustment. The system uses a drive mechanism with motor, transmission gears, and lead screw to automatically adjust the height of the mounting plate and hanger arm according to different vehicle body types, enabling the system to adapt dynamically to varying production requirements without manual intervention
Solution Approach 2:
The system incorporates sensors (proximity sensor, position sensor) that automatically detect vehicle body type and trigger the appropriate height adjustment sequence. The control unit processes sensor signals and autonomously controls the drive mechanism to adjust the hanger arm height, making the system self-regulating and eliminating the need for manual measurement and adjustment operations
2Adaptability or versatility
If multiple tools are prepared for different vehicle types in clamp conveyance method, then adaptability is improved, but device complexity increases due to space requirements for tool accommodation
Solution Approach 1:
The hanger system uses a universal mounting plate with multiple holes arranged in different patterns. By selectively positioning holes and adjusting the mounting plate height, a single hanger arm can accommodate various vehicle body types, eliminating the need for multiple specialized tools and reducing spatial requirements for tool storage and changing mechanisms
3Adaptability or versatility
If tool changing device is used to switch grippers for different vehicles, then adaptability is improved, but loss of time increases due to tool changing operations
Solution Approach 1:
The system pre-arranges multiple holes in the mounting plate at different positions and orientations before production begins. When a vehicle type change is detected by sensors, the system quickly repositions the mounting plate to align the appropriate hole pattern with the coupling pin, eliminating the need for time-consuming tool changing operations and enabling rapid adaptation to different vehicle types

AI summary
A system for changing a height of a hanger mounting plate, may include a frame; a hanger arm fixing device mounted at an upper side of the frame in a longitudinal direction of the vehicle body to be movable in the longitudinal direction of the vehicle body and fixing both sides of the connecting blocks; a pin fixing device which is mounted at a center portion of the frame to be movable in a width direction of the vehicle body and separates or couples the coupling pin from/to the connecting block; and a mounting plate height adjusting device mounted at a lower side of the center portion of the frame to be movable in the height direction of the vehicle body in a state in which the mounting plate height adjusting device supports a lower portion of the mounting plate, and adjusting a height of the mounting plate.
