Belt Grinding Module Coupling Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing belt grinding devices require significant labor and time to couple and detach modules due to the need for multiple screw connections, making the process cumbersome and inefficient.
Innovation Solution
A belt grinding device with a coupling element featuring a bolt and clamping bolt system that allows for easy movement between a release and coupling position, enabling secure connection between modules without the need for tools, using a clamping bar and quick-action clamping screws for a simple and secure mechanical link.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screw connections are used to connect belt grinding modules, then a secure mechanical connection is achieved, but the coupling and detaching process requires significant labor and time
Solution Approach 1:
The connection system is segmented into a coupling element with bolts on one module and a counter-element with clamping bolts and openings on the other module. This segmentation allows the connection to be made through simple insertion and clamping actions rather than requiring multiple screw connections, thereby reducing the time and labor needed for module coupling while maintaining secure mechanical connection.
2Reliability
If multiple screw connections are made to firmly connect modules, then a stable mechanical link is achieved, but the process becomes cumbersome and requires tools
Solution Approach 1:
The fastening function is extracted from the traditional screw connection system and implemented through a dedicated clamping bolt mechanism. The clamping bolt, when moved to the coupling position, secures the bolts in the openings without requiring tools, thus maintaining connection stability while greatly improving ease of operation.
Solution Approach 2:
The coupling element and counter-element are designed to self-secure through the clamping bolt mechanism. Once the bolts are inserted into the openings, the clamping bolt automatically secures them in place, creating a reliable connection without requiring additional tools or complex fastening procedures.
3Ease of operation
If a simple coupling mechanism is used to reduce labor, then ease of operation improves, but the mechanical connection may be less secure against twisting or shifting
Solution Approach 1:
The connection stability is enhanced by adding a clamping dimension to the simple insertion mechanism. The clamping bolt provides a third dimension of control (clamping force) in addition to the insertion motion, creating a secure connection that resists twisting and shifting while maintaining ease of operation through the straightforward clamp-and-lock action.

AI summary
A belt grinding device (10) has at least two belt grinding modules (12, 14) that can be coupled to each other, wherein a coupling element is provided on a first of the two belt grinding modules (12, 14) which can be coupled to an associated counter element on a second of the two belt grinding modules (12, 14) in order to connect the two belt grinding modules (12, 14) to each other, wherein the coupling element has at least one bolt (20, 22, 24, 26) projecting from a surface (13) which can be inserted into an associated opening (32, 34, 36, 38) on a clamping latch (28, 30) on the counter element, and wherein the clamping latch (28, 30) is located between a release position in which the at least one bolt (20, 22, 24, 26) is inserted into the associated opening (32, 34, 36, 38) is insertable or removable from this, and is movable to a coupling position in which the at least one bolt (20, 22, 24, 26) is secured against loosening in the associated opening of the clamping bolt (28, 30) (Fig. 1).
