Robot tool changing transformed

Whether it is for a high payload robot changing spot welding guns in the automotive sector, or smaller robot systems performing multiple handling or assembly operations, today’s tool-changing technology makes it possible to maximise robot flexibility.

Stäubli says that its MPS series robotic tool changers increase productivity for robots in all payload categories from all major manufacturers. Compared with the limited functionality of early-day tool changers, Stäubli’s latest-generation systems offer numerous different modules for the transmission of pneumatics, vacuum, signals, data transmission up to 10 Gbit/s, shielding, earthing, RFID tool coding and data storage.

The ability to combine these different technologies and modules makes it possible to configure a solution for a wide range of applications. Notably, the location of the transmission modules is highly flexible, allowing users to position them as required to suit the individual robot’s cable package. The robot-mounted component of the MPS tool changer incorporates all the services required to provide functionality for the various tools that the robot might use in production. On the tool-change element, the only transmission modules required are those relating to the operation of specific tools, which makes it possible to use multiple, individually configured tool elements with one robot mounted element, optimising the return on investment.

Cross-shaped guide surfaces combined with a spring-loaded ball locking system facilitate interconnection between the robot and tool sides of the MPS tool-changer system. This feature makes it possible to maintain the highest levels of precision throughout its entire product lifecycle. The tools always return to their original insertion position with a repeat accuracy of ±1.5 µm.

Stäubli tool-changing systems are available for robot payloads up to 1530 kg.

RoboTrex helps break performance records

The recent installation of a Lang RoboTrex robotic system at the production facility of motorcycle and automotive brake aftermarket specialist, HEL Performance, is enabling one of the company’s Brother VMCs to run unattended 24 hours a day, seven days a week.

Director Simon Lane says: “Over the past few years, rising global demand for our products has inspired us to invest in a range of cutting-edge machine tools and associated equipment. Our highly-efficient Lang RoboTrex system has been a great success in this area. The system’s installation and integration was trouble-free, and as it’s so easy to use that operator training was also very straightforward.

“Now, by ensuring that we can produce master cylinders and calipers 24 hours a day, seven days a week, without stopping, our Lang RoboTrex system has enabled us to realise the full productive potential of the Brother M140X2 VMC it serves,” continues Lane. “In fact, the combination of our Brother VMC and our Lang RoboTrex system has allowed us to break all of our previous efficiency records for the production of cylinders and calipers, and enabled us to keep-pace with ever-increasing customer demand.”

Lang Technik UK director Gareth Barnet adds: “Given the nature and cycle times of HEL Performance’s parts we were confident that the RoboTrex 52 system was the ideal solution to the company’s needs, as dependant on workpiece size, each of the system’s trolleys is able to hold between 30/42 vices, each loaded with workpieces. As the RoboTrex 52 system is able to accommodate four trolleys with a total storage capacity of 120/168 vices, the automated system is able to undertake lights-out production every night.”

Zeroing in on higher output

In the challenging environment businesses operate within today, manufacturers are seeking every opportunity to increase and maintain the highest levels of productivity. Where components require multiple processes, as is often the case in machining operations, minimising set-up time between machining cycles can make a significant contribution to productivity. Zero-point systems allow the clamping of parts with accuracy and speed, reducing set-up time and maximising productive machining time.

The modular SPN zero-point clamping system from Zimmer Group includes a standard version that incorporates all essential functions, such as unlocking and a PLUS connection. In addition, there is an advanced version with an enhanced range of functionality suitable for automated production operations.

Both variants feature positive locking via clamping segments that are specially adapted to the pin contour. This creates a rigid system that can absorb high forces with maximum repeatable accuracy. The product range extends through the use of different types of clamping plates, available in every size and in various configurations. To increase the protection of the particular zero-point clamping system and prevent any intrusion of dirt and debris, there is also an optional automatic seal that reliably protects the pin opening.

The SPN zero-point clamping system offers repeatability of 0.005 mm due to its sophisticated design. Thanks to its high clamping forces and consistent use of tempered stainless steel, Zimmer Group says that the system provides a high-precision, torsion-resistant base that also stabilises any parts with a tendency to vibrate. The zero-point clamping system is able to absorb maximum forces with maximum repeatability, largely due to a principle that uses clamping segments for positive locking in comparison with conventional systems where balls are in point contact.

Consultative design service for injection moulding

Protolabs is now offering engineers a critical ‘missing link’ that will help them find the best manufacturing solution for their parts. The company has launched a new injection moulding consultative design service that will tap into the thinking and problem solving of its 200-strong team of engineers. Samuel Guest, product manager for injection moulding, says: “Our quoting platform is well-known in industry and allows you to upload your CAD model and check its suitability for injection moulding. It even suggests changes that would make it better and save money. You’ll receive your report and quote back within a couple of hours.”
