In the embodiment, the clamp is arranged by separating the left clamp from the right clamp, so that feeding at the upper end and discharging at the lower end can be realized, the processes of discharging and discharging are simple, and the time is saved; the process of feeding at the upper end can be that two workers take one end of the metal pipe 8, move the metal pipe 8 into the opened clamp and release the metal pipe after the clamp is closed; or the mechanical arm is used for clamping two ends of the metal pipe 8 and putting the metal pipe into the clamp, so that the labor intensity is reduced, the mechanical operation is realized, and the mechanical arm is used for taking objects, which is a common technology in the existing factory, so that the technology is not further described here.

The compression roller 23 that sets up in the anchor clamps can carry out self rotation under the effect of first driving motor 29, tubular metal resonator 8 is in the anchor clamps, through compression roller 23 self rotation, can polish the surface of tubular metal resonator 8, detach the iron rust etc. in the tubular metal resonator 8 outside, there is the clearance again between the adjacent compression roller 23, impurity such as iron rust that polishes and detach can fall to the anchor clamps lower part through the clearance, can discharge along with tubular metal resonator 8 together in the ejection of compact, prevented that impurity from piling up in the anchor clamps, influence the operation of other spare parts.

Meanwhile, the metal pipe 8 can also detect and correct the size of the metal pipe 8 in the cavity, and if the size of the metal pipe 8 is too large or the bending amplitude is too large, the size of the cavity is not met, the clamp cannot be matched, and a worker can know the condition; further, the metal pipe 8 itself is seen straight, but there is a bending phenomenon, and when the metal pipe 8 is ground, the bent portion of the metal pipe 8 can be corrected by pressing the metal pipe 8 by the press roller 23.

In addition, the first guide rail 1 and the machine tool 16 are designed to be hollow at a position corresponding to blanking, so that the metal pipe 8 can directly fall to a designed blanking area.

The implementation method of the embodiment comprises the following steps: firstly, starting a second driving motor 14, adjusting the distance between a first frame 4 and a second frame 4 to be proper so as to conveniently place a metal pipe 8 into a clamp, and then closing the second driving motor 14;

and secondly, starting the driving device, opening the clamp, putting the metal pipe 8 into the clamp from the upper part, wherein the length error of the two ends of the metal pipe 8 extending out of the clamp is not more than 10 cm.

Thirdly, starting the second driving motor 14, adjusting the distance between the first frame 4 and the second frame 4 to enable the processing devices 50 on the first frame 4 and the second frame 4 to contact the metal pipe 8, selecting the specific types of the processing devices 50 according to the requirements, and then closing the second driving motor 14;

fourthly, starting the first driving motor 29 to rotate the compression roller 23, and polishing, detecting and correcting the surface of the workpiece;

fifthly, starting the processing device 50 to process the two ends of the workpiece simultaneously; after the machining is finished, the machining device 50 is closed;

sixthly, closing the first driving motor 29, starting the second driving motor 14, enabling the distance between the first frame 4 and the second frame 4 to be longer, and closing the servo motor;

and seventhly, starting the driving device, opening the clamp, releasing the processed metal pipe 8 in the clamp, and simultaneously putting the unprocessed metal pipe 8 into the clamp.

The preferred embodiments of the present invention have been described in detail above, but it is apparent that the present invention is not limited to the above embodiments. The technical idea of the utility model within the scope, can be right the utility model discloses a technical scheme carries out multiple equivalent variant, and these equivalent variants all belong to the utility model discloses a protection scope. In addition, it should be noted that the technical features described in the above embodiments may be separately and independently combined as long as they are within the technical concept of the present invention.
