Controlled emergency stop: ACE safety shock absorbers protect precision components in the aircraft industry
The basic mount of this coordinate measuring machine for the production of parts in the aircraft industry is made of granite and must not be damaged. To avoid damage from operating errors or mishandling, all movement axes were equipped with safety shock absorbers of ACE's productfamily SCS33 to SCS64. If the turntables malfunction the safety shock absorbers decelerate the loads before expensive damage can occur to the granite measuring tables.
Miniature Shock Absorbers - MC5 to MC75
Brake components for pneumatic linear modules
Pneumatic linear modules in miniature slide systems ensure high speeds with constant repeat accuracy. In this design, pneumatic end-of-travel damping was deliberately omitted and shock absorbers from ACE were used. This is because the compact MC5 to MC75 miniature shock absorbers decelerate the movements more safely and quickly when the end position is reached. They always absorb the mass gently and decelerate evenly over the entire stroke. Further advantages: significantly simpler construction, smaller pneumatic valves, smaller maintenance units and lower compressed air consumption.
Miniature Shock Absorbers - SC190 to SC925
Damping system for pick and place machines
ACE miniature shock absorbers optimize production with minimum expenditure. The cycle rate for an assembly line producing electronic components was increased to 3,600 units/hr. The ACE SC190 miniature shock absorbers decelerate the rapid transfer movements on the production line and using soft damping methods optimize the pick up and set down of components. This soft deceleration technique has increased production and reduced maintenance on the portal and rotary actuator modules. The optional side load adaptor protects the shock absorber from high side load forces and increases the operating lifetime. It was possible to reduce maintenance costs by 50% and operating costs by 20%, diminishing energy consumption.
Miniature Shock Absorbers - SC190 to SC925
Impact protection for aircraft
In the course of a robotics project, students equipped quadrocopters with miniature shock absorbers. In order to avoid costly repairs and associated downtime when researching flight characteristics and learning how to use the helicopter, the prospective academics installed the self-adjusting ACE SC650 miniature shock absorbers on both the top and bottom of the helicopter. These reliably protect the batteries, three-phase drives, sensors and an optionally integrated camera from damage in case of a crash.
Industrial Shock Absorbers - MC33 to MC64
Braking systems for gripper carriages
In this design, driven by rodless pneumatic cylinders, two gripper carriages move independently of each other at speeds of 2 to 2.5 m/s. ACE industrial shock absorbers from the product family MC33 to MC64 are used as brake systems, which have to stop a mass of 25 kg up to 540 times per hour in a material-friendly manner. The MC3350 model was used in this case, which allows the sliding stop slides to be adjusted very easily and precisely in the end position. Compared to brakes that work differently, the ACE shock absorbers enable higher travel speeds and shorter cycle sequences. This optimization of the unit in terms of machine loading results in a significant increase in productivity.
Profile Dampers - TUBUS TA
Safety damping for the loading mechanism of lathes
ACE TUBUS profile dampers protect the integrated loading station on a new high speed machining centre. The ACE TUBUS damper is designed to prevent overrun on the high speed loading station of a Camshaft machining centre used in the automobile industry. In the event that the drive train fails during operation or incorrect data is inputted the ACE TUBUS damper absorbs the impact preventing costly damage to the machine. The TA98-40 TUBUS damper impressed engineers with this exceptionally long service life in operation. When used as an emergency stop the TUBUS damper can absorb up to 73 % of the impact energy.
Profile Dampers - TUBUS TA
Safety damping for the loading mechanics of feeding systems
Preventing expensive damage after software errors or power outages is the task of two TUBUS TA17-7 profile dampers. Installed in various linear axes, handling and feed systems, they ensure that there are no uncontrolled impacts of the masses in the end positions. Designed as a cost-effective alternative to the hydraulic end position damping length if pinpoint stopping is not a priority, profile dampers demonstrate their strength: High force absorption in a compact design. Thanks to the co-polyester elastomer material, they also outstrip the service life of competing solutions many times over.
Profile Dampers - TUBUS TS
Protective structures for treadmill drives in space research
When training in zero gravity, a harness with bungee cords is used to ensure that trainees do not become disengaged. Three ACE profile dampers with a linear-working facility are utilized in this case. One so-called TUBUS is positioned in the pneumatic cylinder, while the other two are put in place in the rest of the system. All the dampers have the task of protecting the system if the treadmill drive belts become damaged. Otherwise, the cylinder would reach a very high speed and become seriously damaged at the end of the stroke.
