However, this clamping and fixing method can only fix and clamp the metal tube that matches the size of the arc-shaped clamping part, and the scope of application is narrow.

[0032] The clamping assembly includes a base 2, two bases 2 are distributed and fixedly connected to the fixed block 12 and the telescopic assembly, two groups of rotating plates 4 are rotatably connected to the base 2, the two groups of rotating plates 4 are symmetrically arranged, each group of rotating plates 4 is provided with two, and the two rotating plates 4 are fixedly connected by a support rod 41;

[0033] The rotating sleeves 3 are sleeved on the two supporting rods 41 , and the two rotating sleeves 3 are connected to each other via a flexible friction cloth 31 .

[0034] A groove 21 is formed on the base 2 , and the rotating plate 4 is rotatably connected in the groove 21 via a rotating shaft 42 . The rotating shafts 42 on each set of rotating plates 4 are fixedly connected via a connecting rod 43 .

[0035] A friction wheel 44 is fixedly connected to one end of the rotating shaft 42 away from the connecting rod 43 , and the edges of the two friction wheels 44 fit each other.

[0036] A pneumatic telescopic rod 5 is provided on the rotating plate 4 , and two ends of the pneumatic telescopic rod 5 are distributed and rotatably connected to the two groups of rotating plates 4 .

[0037] The telescopic component is a hydraulic telescopic column 6 , one end of which is fixedly connected to the base 1 , and the other end of which is fixedly connected to the bottom of the base 2 .

[0039] A baffle is fixedly connected to the base 1, and one side of the baffle is in contact with one end of the clamping assembly.

[0040] The working principle of this utility model:

[0041] During use of the metal tube end surface processing device, the metal tube to be processed can be placed on the rotating sleeve 3 above the hydraulic telescopic column 6, and the end to be processed can be fitted with the surface of the baffle plate, and then the hydraulic telescopic column 6 is started. The telescopic end of the hydraulic telescopic column 6 extends to push the base 2, the rotating sleeve 3 and the rotating plate 4 thereon upward until the surfaces of the two flexible friction cloths 31 are fully fitted with the surface of the metal tube. After the surface of the metal tube is fully fitted with the surface of the flexible friction cloth 31, the pressure on each point where the surface of the flexible friction cloth 31 contacts the surface of the metal tube is equal, which can reduce the probability that the metal tube may be squeezed and deformed during the full clamping process, increase the contact area, and improve the static friction between the flexible friction cloth 31 and the metal tube. In addition, because the flexible friction cloth 31 is in a flexible state, when the two flexible friction cloths 31 squeeze the surface of the metal tube under the support of the support rod 41, the flexible friction cloth 31 can adapt to the size of the metal tube. The rotating shafts 42 of the two sets of rotating plates 4 are linked to each other through the linkage rod 43, which can ensure that the force at each position on the rotating sleeve 3 is uniform, and the rotating shafts 42 on the two sets of rotating plates 4 are linked through the friction wheel 44, which can ensure that the rotation of each set of rotating plates 4 is synchronous, so that the pressure of the two rotating sleeves 3 on the surface of the metal pipe is the same, so as to improve the stability in the clamping process. After the metal pipe is clamped and fixed, the electric telescopic rod 7 and the motor 71 can be started. The extension of the telescopic end of the electric telescopic rod 7 can drive the motor 71 and the grinding wheel 72 to approach the end of the metal pipe to be processed until the side of the grinding wheel 72 fits the end face of the metal pipe. After the motor 71 is started, the grinding wheel 72 can be driven to rotate at a high speed. When the side of the grinding wheel 72 fits the end face of the metal pipe, the high-speed rotating grinding wheel 72 can grind the end face of the metal pipe, so that the purpose of processing the end face of the metal pipe can be achieved.

All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
