Three the 3rd claws are carried on dog chuck, the contact surface of each 3rd claw and workpiece is provided with the 3rd rubber blanket；3rd three-jaw card
The 3rd diaphragm pressure sensor is additionally provided with disk.
9. the reciprocating reinforcing fin heat exchanger tube processing positioning method realized according to any one of claim 1~8 described device, its
It is characterised by, comprises the following steps：
(1) workpiece is positioned：Workpiece is installed on clamping device, clamp moving mechanism and clamping rotating mechanism, and passes through clamping
Mechanism, clamp moving mechanism and clamping rotating mechanism clamp workpiece；
(2) plow workpiece：Clamping device and clamping rotating mechanism clamp workpiece respectively, and clamp moving mechanism unclamps workpiece；Processing
Cutterhead outside positioner carries out plow operation, after treating plow, cutterhead withdrawing to workpiece feed to workpiece；
(3) stepping：Clamping device loosens workpiece, and clamp moving mechanism clamps workpiece, and clamping rotating mechanism unclamps workpiece；According to pre-
If move horizontally distance, clamp moving mechanism drives workpiece to be carried forward and moved horizontally；
(4) rotate：Clamping device loosens workpiece, and clamp moving mechanism unclamps workpiece, and clamping rotating mechanism clamps workpiece；According to pre-
If the anglec of rotation, clamping rotating mechanism drive workpiece rotated；
(5) rotating mechanism is clamped to reset：Clamping device loosens workpiece, and clamp moving mechanism clamps workpiece, clamping rotating mechanism pine
Go into operation part；Clamp rotating mechanism and rotate and reset；
(6) circulation performs step (2) to step (5), until the translation distance of clamp moving mechanism reaches default range
Or work pieces process is completed；
(7) clamp moving mechanism resets：Clamping device loosens workpiece, and clamp moving mechanism unclamps workpiece, clamping rotating mechanism folder
Clamping of workpieces；Clamp moving mechanism retreats and moves to initial position；
(8) circulation performs step (2) to step (7), until completing the processing of workpiece, forms enhanced fin heat exchanger tube finished product.
