Mindman

Mindman MCHA spring open angular pneumatic gripper with an operating angle from -10 to 30°. The external holding force is 30 N @ 5 bar (6.74 lbf @ 73 psi). The pressure range is from 2 to 7 bar (29 to 101.5 psi). The gripper has a stainless steel piston with aluminum front and back covers, the jaws are made of carbon steel and the seal is NBR. As standard, the piston is magnetic allowing for magnetic position sensors. The gripper is suitable for a temperature range from -5 to 60°C (23 to 140°F).

Description

This two-jaw 30° angular pneumatic gripper from Mindman can be used for pick-and-place operations. The gripper jaws are opened and closed around a central pivot point with a closed angle of -10° and an open angle of +30°. This single acting (normally open) gripper has one air port and handles objects using an external grip. The effective force for external operation is 30 N (6.74 lbf). The effective force is calculated for each gripper jaw at 5 bar and at a lever arm of 20 mm.

The internal air cylinder has a 20 mm bore size. It has an operating pressure of 2 to 7 bar (29 to 101.5 psi) and a maximum operating frequency of 180 cycles/min. The air ports have a size of M5×0.8.

The gripper has a stainless steel piston with aluminum front and back covers and the seal is NBR, making it durable and capable of operating within a temperature range of -5 to 60°C (23 to 140°F).

The jaws are made of carbon steel. The fingers have through holes, allowing you to mount an additional custom gripper design onto them that is optimized for your application. It is recommended to design lightweight fingers with low inertia. This will limit shocks at the stroke ends. Also, please use a flow control valve to limit the jaw speed to reduce the impact when the jaws fully open or close. Make sure that the jaws are in parallel position when grippers at closing position. Use Mindman’s easy to use instructions (see Download section) to calculate the required force.

As standard, the piston has a magnetic ring, which enables the use of a magnetic position sensor. The position sensor is slid into place along the housing grooves and secured with a set screw.

Pros:

  • Thanks to the angular shape, it can be used with different part shapes and sizes
  • It has three mounting interfaces, allowing for flexibility and many design options
  • Suitable for a magnetic position sensor thanks to the magnetic piston
  • A custom finger design can easily attach to the jaw, replacing the current fingers, to optimally grip your work piece

Cons:

  • Only for external griping, select a spring closed or double acting gripper for internal gripping
  • The jaws cannot open 180 degrees like the Mindman MCHY
  • If the object has two opposing flat surfaces, choose a parallel gripper. They can handle some dimensional variations
  • Cannot be operated in freezing environments

MCHA series

The MCHA pneumatic grippers are highly accurate pick-and-place devices. They have a two-jaw 30° angular design. They are available in double acting or single acting versions. The cylinder diameter range is 12-32 mm. The stroke ranges from -10 to 30° and the maximum arm length is from 30 to 85 mm. The gripper delivers an effective force up to 175 N at 5 bar (39.3 lbf @ 72.5 psi). The operating pressure is 1.5 to 7 bar (21.8 to 101.5 psi) and the maximum operating frequency is 180 cycles/min. They have carbon steel jaws and a stainless steel piston, a body from anodized aluminum with recessed sensor grooves. The seal is made of NBR. The temperature range is from -5 to 60°C (23 to 140°F). The three mounting interfaces on different sides allow for flexible installation. It has M3x0.5 or M5x0.8 air ports to connect with a pneumatic hose.
