The processing and positioning device as claimed in claim 1, wherein the left carrying bar and the right carrying bar are provided with at least one set of groove bars for limiting the left and right sides of one or more pieces of workpieces to be processed, and the distance between the bottom surfaces of the corresponding groove bars of the left carrying bar and the right carrying bar is greater than the length of the workpieces to be processed.
4. The tooling positioning apparatus of claim 1, wherein the left positioning bar and/or the right positioning bar is provided with a protective assembly.
5. The processing positioning device according to claim 1, wherein the positioning mechanism is fixedly provided with a limiting component, the aggregate box is placed on the positioning table through the limiting component, and the positioning mechanism is further provided with a locking component which can be detachably fixed on the aggregate box.
6. Machine tool, characterized in that it comprises a machining positioning device according to any one of claims 1 to 5, a numerically controlled machine tool and a manipulator for taking the change between said machining positioning device and said numerically controlled machine tool.
7. The processing method is characterized by comprising the following steps:
a: the material collecting box is arranged on the positioning table and comprises a lower transporting strip for limiting the up-and-down direction of the workpiece to be processed, a left transporting strip and a right transporting strip for limiting the left-and-right direction of the workpiece to be processed, the workpiece to be processed in the material collecting box is lifted upwards by a certain height under the action of the lower positioning rod, and then the left positioning rod moves radially and accurately positions the workpiece to be processed in the left-and-right direction together with the right positioning rod;
b: after positioning is completed, the mechanical arm grabs the workpiece to be machined and places the workpiece to be machined on a machining table of the numerical control machine tool, and after the machining table finishes clamping the workpiece to be machined, a machining head of the numerical control machine tool machines the workpiece to be machined;
c, after the processing is finished, the mechanical arm grabs the processed piece and places the processed piece in the material collecting box;
d: and C, the manipulator grabs the next workpiece to be processed or returns to the step A.
8. The process of claim 7 further comprising, prior to step C:
when the processing head processes the workpieces to be processed, the manipulator returns to the processing positioning device, the manipulator grabs the next workpiece to be processed and transfers the next workpiece to be processed to the vicinity of the processing table for waiting until the previous workpiece to be processed is processed, other idle grabbing components of the manipulator grab the processed workpiece, the next workpiece to be processed grabbed for the second time is placed on the processing table after rotation, then the workpieces grabbed by the other grabbing components are placed in the material collecting box, then the next workpiece to be processed is grabbed and transferred to the vicinity of the processing table for waiting until the workpieces are not left in the material collecting box.
