The number of the second slots 11 on the ratchet wheel 5 is the same as the number of planes to be machined on the outer circumferential surface of the part, and the second slots 11 are uniformly distributed on the wheel surface of the ratchet wheel 5. Similarly, the number of the first locking grooves 10 on the locking wheel 4 is the same as the number of planes to be machined on the outer peripheral surface of the part, and the first locking grooves 10 are uniformly distributed on the wheel surface of the ratchet wheel 5.
In this embodiment, the number of the second slots 11 on the ratchet 5 and the number of the first slots 10 on the locking wheel 4 are two, the outer peripheral surface of the part 21 to be machined is machined into two flat surfaces, and the pawl 7 enters one second slot 11 every time the ratchet 5 rotates 180 °. For another example, when the outer peripheral surface of the disc part needs to be machined into a tetrahedron, four second clamping grooves 11 are uniformly distributed on the wheel surface of the ratchet wheel 5, each time the ratchet wheel 5 rotates by 90 degrees, the pawl 7 enters one second clamping groove 11, at the moment, the ratchet wheel 5 cannot move in the reverse direction, and then the locking wheel 4 cannot move in the reverse direction, so that the gear overrunning mechanism 3, the locking wheel 4, the ratchet wheel 5 and the tray 6 are integrally locked and positioned and cannot rotate.
Taking a disc-type part as an example, when the processing device is used for processing the outer periphery of the part, the basic process is as follows: the whole machining device is fixed on a sawing machine or a milling machine by bolts from the fixing plate 1, so that the peripheral surface of the part can be cut by a saw blade or a milling cutter. Then, after the disk-type part to be machined 21 is sleeved on the mandrel 2 and is fixed with the mandrel 2 into a whole through the part pressing plate 20, the driving device 8 is started to complete a stroke to drive the gear overrunning mechanism 3 to rotate anticlockwise by an angle, the position of the part to be machined 21 which is already in indexing is locked through the return stroke of the driving device 8, the part to be machined is cut downwards by the saw blade to obtain a machined surface after the part to be machined is completed, then the driving mechanism 8 continues to drive the gear overrunning mechanism 3 to rotate 180 degrees to complete the indexing of the part to be machined 21, the position of the part to be machined 21 is locked through the return stroke of the driving device 8, and the part to be machined is cut by the saw blade to complete the machining of the other surface.

Meanwhile, by utilizing the arrangement of a specific position between the locking wheel 4 and the ratchet wheel 5, utilizing the locking hook 9 to lock the locking wheel 4 in a positive/negative direction when the return stroke of the driving mechanism 8 is finished, and utilizing the pawl 7 to lock the ratchet wheel 5 in a negative/positive direction, the whole formed by the mandrel 2, the gear overrunning mechanism 3, the locking wheel 4, the ratchet wheel 5 and the tray 6 is locked and positioned, and the whole rotation caused when a part fixed on the tray 6 is cut is avoided, so that the cutting tool is prevented from being damaged and the processing of the peripheral surface of the part is prevented from being influenced. In addition, the gear overrunning mechanism 3 is utilized to avoid the problem that the driving mechanism 8 is blocked with the locked whole body and cannot return when returning, so that the driving mechanism 8 can realize continuous processing and accurate indexing of the peripheral surface of the part only by reciprocating motion, and the problem that the part with two flat surfaces which are not convenient to be prefabricated mainly depends on expensive numerical control equipment and a manual indexing tool when a part blank is manufactured at present is solved.
