Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grinding devices for riveted joints on sheet metal require manual movement, leading to arm tension and aches, and are prone to deviation, which can result in damage to the sheet metal during the grinding process.
Innovation Solution
A grinding device with a lateral plate, legs, moving plate, springs, a grinding wheel, oscillating plate, and a driving motor that allows the grinding wheel to be positioned and operated automatically, reducing manual effort and minimizing the risk of deviation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual grinding device is used, then portability is improved, but operator fatigue and deviation risk increase
Solution Approach 1:
The grinding device employs dynamic positioning mechanisms including guide rails with sliders, spring-loaded pressing components, and adjustable arms that can adapt to different rivet positions. The device transitions from static manual holding to dynamic automated positioning, reducing operator fatigue while maintaining grinding accuracy through mechanical guidance systems.
Solution Approach 2:
The device incorporates self-positioning features where the grinding wheel automatically aligns with rivet heads through guide rails and positioning pins. The spring mechanism provides automatic pressure regulation, and the device structure enables self-adjustment to different rivet configurations, reducing the need for constant manual intervention and positioning corrections.
2Manufacturing precision
If automated positioning is implemented, then grinding precision is improved, but device complexity increases
Solution Approach 1:
The grinding device is divided into modular functional segments: a positioning system with guide rails and sliders, a grinding mechanism with wheel and motor, a pressing system with springs and arms, and a base structure with legs. Each segment performs a specific function and can be independently adjusted or maintained, achieving precise positioning without requiring an overly complex integrated design.
Solution Approach 2:
The device uses intermediary mechanical elements such as guide rails as mediators between the operator and the grinding wheel, positioning pins as intermediaries for alignment, and spring mechanisms as intermediaries for pressure control. These intermediary components simplify the overall control complexity while ensuring accurate and consistent grinding positions.

AI summary
A grinding device for raised joints of rivets on sheet metal is provided, including a lateral plate, legs, a moving plate, first springs, a first bearing seat, a sleeve, a grinding wheel, a moving bar, a 7-shaped plate, a vertical bar, a second spring, an oscillating plate, etc. The legs are fixedly connected, in a symmetric manner, to left and right sides of the bottom of the lateral plate. A through hole, which has a function of guiding, is formed on a left side of the lateral plate. The moving bar is located in the through hole. In the present disclosure, a driving motor is started to rotate the grinding wheel, the grinding device is moved to enable the grinding wheel to be located above a raised joint, and then the oscillating plate is pulled so that the grinding wheel can move downward to grind the raised joint.
