Remote maintenance for novel gripper sensor
The FPS-F5 multiple position sensor is the first gripper sensor with a remote maintenance function.
With only a few modifications the Kontec MTC can be changed from a centric vice to a vice with a fixed jaw or even to a double clamping vice.
This flexibility means a tremendous reduction of initial costs compared with the price of specialised clamping vices.
The fixed base jaw can be equipped with top jaws from the extensive Schunk jaw program allowing the MTC vice to achieve jaw strokes in the range of 40 to 70mm.
Used as a fixed jaw vice, by rotation of the spindle, the moving jaw is guided towards the workpiece and is clamped by means of a torque wrench (optional).
In this situation, the indexing pin is in the extreme left bore and fixes the left base jaw in a fixed position.

Magnetic clamping plates provide flexibility
Magnetic clamping system that uses a square pole electro-permanent magnet is a work holding device for rough or fine cutting applications on milling machines and machining centres.
Chuck cuts cycle times by 40%
Electro-pneumatic control system in power chuck lets workpiece be preclamped concentrically at a predetermined low clamping pressure, so the part can be adjusted within the desired tolerance.
Used as a double vice, the indexing pin is removed completely.
The spindle is then held in a floating position, enabling clamping of irregularly large workpieces.
The fixed and secured middle jaw serves as the stop or fixturing element.
Used as a centric vice, the indexing pin is inserted in the middle bore.
This fixes and locks the entire spindle in position.
By turning the drive spindle both base jaws are guided centrically towards the workpiece by turning the spindle.
The Kontec MTC has extremely compact dimensions and this limited use of space enables the user to optimally use the available machining area.
The MTC unit is equipped with a mounting groove as well as bores for connection to the machine table.
Using a torque wrench the spindle can be adjusted and achieves clamping forces from 15 to 25kN.
The MTC is available in three sizes with a jaw width of 60, 80 or 100mm and its chip-repelling contour and robust functional components guarantee to keep maintenance to a minimum whilst providing an exceptionally long product life span.
The high degree of robustness and flexibility enable the MTC vice to work hand in hand with the Schunk Unilock Quick-Change-Pallet System.
Also on show will be the PGN-plus and PZN-plus grippers.
Ideal for situations where long fingers and high gripping forces often stand in conflict with the requirement of having compact sizes of the gripper housing, this exciting new range offers 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 whilst 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 140 and 13,000N.
Additionally, the PZN-plus three-finger centric gripper is offered in seven sizes offering gripping forces from 580 to 38,700N.
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, with or without internal/external acting spring pressure for additional clamping force or safety facility and 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.
This will save precious time and additionally is free of charge.
With the PGN-plus and PZN-plus gripper series Schunk offers universal grippers for all kinds of application.
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 580 to 7100N.
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 free introductory details about products from Schunk Intec ...
