The ratchet processing device refers to a set of continuous and sequential processing equipment and process flow specially designed for mass production, high efficiency and stable production of ratchet parts. The raw material of the ratchet is round steel, which is roughed and semi-finished by a numerical control lathe to remove most of the excess and form a basic shape, and the tooth shape is processed so that the round steel is processed into a ratchet.

Then the rotating shaft is rotated again to clamp the first workpiece reversed on the workpiece reversing device by the other extension plate and the clamping cylinder and clamping arm below it, and the second workpiece after front end turning is sent into the workpiece reversing device for reversing. The grabbing mechanical arm is moved and the rotating shaft is rotated, so that the other extension plate and the clamping cylinder and clamping arm below it are aligned with the third workpiece on the material disc. Then the first workpiece is sent into the rear end lathe for rear end turning. After turning, the first workpiece is placed on the material disc, and the third workpiece is sent into the front end lathe for front end turning. Then the second workpiece is grabbed from the workpiece reversing device, the third workpiece is sent into the workpiece reversing device, and the second workpiece is rear end turned. The process is repeated, so that the grabbing mechanical arm can simultaneously carry out feeding and front end turning during the reversing and front end turning and rear end turning of the workpiece, without waiting for each workpiece to be completely processed before grabbing a new workpiece, thereby improving the processing speed.

Then, the longitudinal rotating arm 52 and the front and rear moving arm 53 of the grabbing mechanical arm 5 are used to move the workpiece facing upward to the position of the grabbing claw 65 of the workpiece reversing device 6. The workpiece is clamped by the grabbing claw 65 of the workpiece reversing device 6 at the end that has been machined.
