Robot Seventh Axis

The seventh axis of robots is mainly used to expand the operating radius of robots, expand the range of robot functions, and is mainly applied in industries such as welding, casting, mechanical processing, intelligent warehousing, automotive, aerospace, etc.

We are committed to providing excellent walking axis solutions for every robot through continuous technological advancement. Provide excellent load-bearing platforms, reducers, and drag chains for each robot.

Basically, welded track bases are used, and many machine tools also use welded bed bodies, which is closely related to their related technologies. In China, many large machine tool manufacturers have also tried to use welded bed bodies, but they have basically failed. Firstly, there is no accuracy, and secondly, there is significant deformation during use, which is basically difficult to adjust. In other words, there are significant differences in materials, welding processes and equipment, mechanical processing processes and equipment in China, so the seventh axis stroke of robots is relatively long. It is currently difficult to achieve accuracy and service life. So using a cast base, the performance of the cast base is obviously much better than that of the welded base, with significant advantages in accuracy, deformation, and vibration absorption.

The new robot walking system adopts API laser interferometer to measure its walking positioning accuracy, straightness, repeat positioning accuracy, etc., and issue a qualified measurement report for each product.

The main technical parameters of the seventh axis system of the robot are as follows:

Load capacity 2 tons

Journey 50m

Repetitive positioning accuracy ± 0.05mm

The straightness of the guide rail is 0.3mm/12m

Mobile speed 0~30m/min (adjustable)

Intermittent operation mode

Mobile acceleration 2m/s2

Total number of workstations 8 (quantity to be specified by the customer)

Drive motor 40Nm

Casting base width 500mm

Workbench width 550mm

The seventh axis system of the robot mainly includes:

1. Casting base

2. Heavy duty linear guide rail

3. Large modulus grinding high-precision gear rack

4. Servo system and planetary gearbox

5. Sustainable self lubrication system that provides lubrication

6. Dust prevention system (fully enclosed style)

7. Travel limit switch

8. Buffer device

Danieli provides standardized products in lengths of 1000mm, 2000mm, 3000mm, 4000mm, and 6000mm. Therefore, they can be combined into any trajectory length to meet various customer needs. Standardized module products also provide strong support for customers' convenient installation, debugging, and low maintenance and after-sales costs.
