Poor weld detection system
Robo-navi-Double

Overview

Robo-navi-Double detects with a high accuracy whether or not the nut and the workpiece are set correctly right before welding.
It prevents manufacturing defectively welded products.
It is a poor weld detection system developed for robots and automated machinery in nut welding.
 
 

- SMK has acquired the intellectual property rights both inside and outside Japan.

Robo-navi-Double Slide Unit

Reduce production time to 1/2

Vertical movement of the guide pin enables high-speed movement of the workpiece, and to shorten tact time.
 

Positioning is much easier

The replacement work can be done easily without time-consuming adjustment and centering work that occurs when replacing each part and electrode.

Two types of nut on one welding machine

This Slide Unit Double Type has two levels of height. A welding machine can be used for two types of nut welding.

Holder has excellent cooling effect! Six sizes available.

Internal water-cooling system that directly cools the inside of the holder reduce abrasion and spatter adhesion caused by heat on the electrode part.
Slim and compact body without water jacket or intermediate adapter allows minimum interference with the workpieces.
 
We have 6 standard sizes for inner water-cooling holder.
Please contact us for other sizes.
 

Holder outer dia. Φ25 Φ32
Suitable nut size M4・M5・M6・M8 M10・M12・7/16
Holder lenghth 150㎜・200㎜・250㎜ 150㎜・200㎜・250㎜

Ceramics guide pin specification

Ceramics guide pin (Silicon nitride) is included as standard equipment.
Ceramics guide pin has high hardness and long service life. Because there is no electrocorrosion, nor abrasion.
Also there is no adhesion of spatter and jamming of nut.
The use of silicon nitride guide pins stabilizes navi measurements.

No friction!

Adoption of high-powered cylinder has reduced friction between the workpiece and the guide pin, and it raises operation rate.
