Description

Technical Field

[0001] The utility model belongs to the technical field of water meter production, and particularly relates to a water meter grasping mechanism. Background Art

[0002] An intelligent water meter is a new type of water meter that uses modern microelectronics technology, modern sensing technology, and intelligent IC card technology to measure water consumption and conduct water use data transmission and settlement transactions. Compared with traditional water meters, intelligent water meters have significant progressiveness.

[0003] During the production process of intelligent water meters, multiple inspection processes are required, and multiple station transfers are involved during the inspection process. The traditional process method is to use clamping jaws to clamp and transfer intelligent water meters;

[0004] However, intelligent water meters usually come with electronic module boxes, and due to different models of intelligent water meters, the forms of the electronic module boxes are also different. Common intelligent water meters are divided into vertical water meters and horizontal water meters. For a vertical water meter, the first end of the electronic module box is installed on the base meter of the water meter, and the second end is located above the water outlet of the water meter. For a horizontal water meter, the electronic module box is installed above the water inlet of the water meter;

[0005] Therefore, ordinary clamping jaws cannot be adapted to different types of water meters with electronic module boxes at the same time. And due to the existence of the electronic module box, when an ordinary single clamping jaw is used for clamping, the clamping force is likely to be small, and the center of gravity is unstable, resulting in the water meter slipping. If the clamping force is too large, it may damage the water meter. Summary of the Utility Model

[0006] To solve the problems raised in the above background art, the utility model provides a water meter grasping mechanism to solve the problems that ordinary clamping jaws cannot be adapted to different types of water meters with electronic module boxes at the same time, and due to the existence of the electronic module box, when an ordinary single clamping jaw is used for clamping, the clamping force is likely to be small, and the center of gravity is unstable, resulting in the water meter slipping. If the clamping force is too large, it may damage the water meter.

[0007] To achieve the above object, the utility model provides the following technical solutions:

When clamping, the two horizontal clamping ends of the servo front clamping jaw are in pressing contact with both sides of the water meter base meter, and the two horizontal clamping ends of the servo rear clamping jaw are in pressing contact with both sides of the electronic module box.
