Pneumatic grippers have longer fingers
Grippers are equipped with a precise multi-tooth guidance so that forces and moments are spread over several surfaces, thereby enabling longer fingers.
In situations where long fingers and high gripping forces often stand in conflict with the requirement of having compact sizes of the gripper housing, the PGN-plus and PZN-plus from Schunk offer innovative solutions to this problem The grippers are equipped with a precise multi-tooth guidance
Forces and moments of the gripper are spread over several surfaces of a multiple-tooth guide, enabling longer fingers.
The base jaws are precisely adjusted into the housing (0.01mm) in order to achieve a low guide clearance and to minimise wear.
The base jaws are synchronised by a stable wedge hook mechanism, which is guided via surface contact.
The required forces are achieved by a pneumatic piston and the gripper offers a range from 2 to 35mm stroke per finger.
The PGN-plus two-finger parallel grippers are available in eight sizes to cover a range of gripping forces between 140N and 13kN.
Additionally, the PZN-plus three-finger centric gripper is offered in seven sizes offering gripping forces from 580N to 38.7kN.
The finger positions can be sensed by magnetic or inductive proximity switches or by a freely programmable position control system.
When using the FPS position control system, up to five positions per stroke can be monitored.
Each gripper can be ordered in a heat resistant or corrosion-proof design, but also in combination with a dust cover or with a spring operated pressure plate.
Engineering drawings in all current 2D and 3D CAD formats are available for download from the Schunk website.
Taking these exciting workholding solutions to new heights, Schunk has extended its portfolio with the new PZV four-finger concentric gripper - the latest addition to the exceptional product range.
Whereas two- and three-finger grippers cater for most industrial handling tasks, four-finger grippers are required in instances where cylindrical workpieces are magazined on one level.
Whereas three finger-grippers have at least one finger that would always collide with neighbouring components, the PZV profits in spacious circumstances with its four fingers.
The four-finger PZV is the ideal gripper module for holding coplanar and cylindrical workpieces at a high positioning accuracy.
Even at other applications, the PZV convinces with its high degree of flexibility.
It can be used as a parallel gripper for clamping with two different pairs of top jaw fingers without problems and without having to set up the fingers.
As a result the setup times can be permanently optimised - without interrupting the running operation.
Working with the strong pneumatic pistons, stable wedge hook system and the robust multi-tooth guidance, the PZV ensures outstanding capacity with high gripping forces.
The PZV is available in four sizes of 64, 100, 160 and 200mm - achieving gripping forces from 580N to 7.1kN.
With strokes from 4 to 16mm, it can be used to cover an extensive range of workpieces.
The technical finesse of the PZV is proven in applications of the gripper module, in the PGN-plus and PZN-plus.
The PGN-plus and PZN-plus demonstrate established technology that offer high torque transmission.
Like the PGN-plus and PZN-plus, the PZV has a large assortment of accessories available such as magnetic and inductive proximity switches, positioning sensors, and finger blanks.
In addition it can be used together with rotary distributors and other robot accessories in the normal manner. Request a free brochure from Schunk Intec ...
