Positioner is rectified to anchor clamps

The utility model discloses an including positioner is rectified to anchor clamps, anchor clamps are installed in four -axis linkage mechanism, and four -axis linkage mechanism installs on the board, still including calibration block, calibration block has a datum plane and a correcting plane, and correcting plane is located the opposite of datum plane, and correcting plane and datum plane constitute and be greater than 0 degree and be less than 90 degrees contained angle to constituting calibration block one end and favoring and the thin structure of the other end, calibration block's correcting plane 's inclination is the demand angle, calibration block installs the correction location structure that formation can be moved about on anchor clamps. The utility model discloses processing angle according to the product has designed the calibration block that the angle meets the requirements earlier, then utilizes calibration block and anchor clamps and four -axis linkage mechanism to cooperate in order to recti
