PURPOSE:To rest positioning easily and reliably, in a welding positioner, by manually operating horizontal and vertical movement motors and storing the table position then positioning the table based on a signal fed from a memory means. CONSTITUTION:A table 1 is journaled to a receiving board 2 and a driven gear 4 is fitted over a rotary shaft 3 so as to obtain a driving power through a horizontal rotation motor 5 and a reduction gear 6. The rotation of the driven gear 4 is stored in a memory means 8 through a encoder 7. Consequently, the motor 5 can control forward/rearward rotation through a manual switch 9 and can be operated by a signal fed from the memory means 8. On the other hand, the receiving board 2 is journaled rotatably up and down to a positioner body 10 and a driven gear 12 receives driving power through an up/down rotation motor 13 arranged on the positioner body 10 and a reduction gear 14, and said rotation is stored in the memory means 8 through an encoder 15. Consequently, when the memory in the memory means 8 is called out and signals are fed to the motors 5, 13, the table 1 can be set accurately. |
