Lateral Gripper Multi-Point Contact for Drill Box Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost of vacuum suction equipment for handling drill boxes during manufacturing and transportation poses a significant investment burden, and existing solutions fail to provide a stable and cost-effective method for gripping and transporting drill boxes.
Innovation Solution
A lateral gripper with a simple structure, comprising a gripper mount, two gripper jaw modules, and positioning devices, which allows for multi-point contact and stable gripping of drill boxes, eliminating the need for expensive vacuum suction systems by using a driving device to move the gripper jaw modules between open and close positions and employing elastic clamping positioning devices for secure grip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vacuum suction equipment is used to handle drill boxes, then the drill boxes can be gripped and transported, but the investment cost is high and requires long-term recovery
Solution Approach 1:
The gripper is divided into two independent jaw modules, each with its own positioning devices. This segmentation allows for a simpler, more cost-effective structure compared to expensive vacuum suction systems, while maintaining reliable gripping through multi-point contact at the fingertips of the jaw modules
Solution Approach 2:
The patent replaces the vacuum suction system (pneumatic/hydraulic system) with a purely mechanical gripping system using jaw modules and positioning devices. This substitution eliminates the need for complex vacuum generation and control equipment, significantly reducing investment cost while providing stable mechanical gripping through elastic clamping force
2Ease of manufacture
If a simple and lightweight gripper structure is used, then installation is easy and cost is low, but gripping stability may be compromised
Solution Approach 1:
The jaw modules are designed to be movable along the linear sliding groove, allowing dynamic adjustment of the gripping position and force. The elastic positioning devices provide dynamic clamping force that adapts to the drill box position, ensuring stable gripping despite the simple overall structure
Solution Approach 2:
The positioning devices extend the gripping function from simple lateral clamping to multi-point contact in three dimensions. The positioning devices protrude from the jaw fingertips to contact specific points on the drill box, adding a vertical dimension to the gripping action and significantly enhancing stability without complicating the basic jaw structure

Function Achieved in This Case
The lateral gripper provides a stable and cost-effective solution for gripping and transporting drill boxes, reducing the risk of damage and eliminating the need for expensive vacuum suction equipment, thereby lowering installation costs and improving delivery accuracy.
Implementation Method 1
The positioning device comprises a spring, a steel ball and a limiter. The spring is mounted in the mounting hole, the steel ball is supported on the spring and position-limited by the limiter

AI summary
A lateral gripper includes a gripper mount, and two gripper jaw modules assembled on the gripper mount. Each gripper jaw module includes a sliding block and a gripper jaw. The sliding block drives the gripper jaw to slide on the gripper mount. The gripper jaw is configured to grip a drill box by multi-point contact, so that the freedom of the drill box is restricted, and the drill box can be stably carried by the gripper jaw modules.
