An introduction to the purpose and functions of dolphins
Improve fixture changing efficiency of machining center and other equipment.
The Delphin/Dolphin transfer system consists of a chuck and a pull rod
The repeated positioning accuracy of collet and tie rod is 0.005mm (±0.0025mm), and the clamping force of collet is very stable over 10000N.
According to the equipment travel, the size of the workpiece free and flexible design and layout.
The exchange pallet or worktable can be manufactured according to the fixture requirements of the workpiece.
The flexible ring structure (PAT) is adopted to avoid the weakness of the previous cone positioning, and the repeated positioning accuracy in z-axis direction (height direction) is greatly improved.




The workpiece, fixture and exchange table can be fixed correctly without manual handling adjustment

The workpiece, the fixture, the exchange table has a single ordinary worker can be completed

The innovation of the dolphin chuck is the use of a flexible structure in the Z-direction cone, improving the cone
Weaknesses in positioning. So that the replacement system precision greatly improved.
Movable part は 3 r club alone の structure に よ っ て high-precision を between long-term maintain で き ま す.
Movable flexible construction (patented by 3R) technology allows the system to maintain high precision over a long period of time
Rod is introduced

The pull rod is divided into 3 kinds, which is used for the change between the self-made tray and collet.
The error of tie bar spacing relative to the allowable mounting error of collet is ±0.015mm
Installation error is ±0.015mm, but repeat positioning accuracy is maintained at ±0.0025mm (±2.5)
Type of tie rod

Tray production

It is very difficult to achieve an error of 0mm in the mounting hole of the collet and pallet rod.
The tray case for the four collet in figure 1, the tie rod A being the full circumference orientation (origin). Rod B is the direction of the Angle. The tie rod C is not positioned and only plays a tensioning role.
In Figure 2, the error installed is within ±0.015㎜. Pull rod A position repeat positioning accuracy to maintain in ±0.0025㎜
