Example Embodiment
[0025] Example one
[0026] Such as figure 1 As shown, a steel pipe inner and outer integrated automatic grinding system 1 includes an inner wall grinding device 10, a steel pipe fixing device 20, an outer wall grinding device 30, and a drive system. The steel pipe inner and outer integrated automatic grinding system 1 can synchronize the inner and outer walls of the steel pipe 9 Grinding and polishing. Such as figure 2 As shown, it is a schematic structural diagram of the inner wall grinding device 10 in an open state when it is working. The inner wall grinding device 10 includes an outer sleeve 101, an inner sleeve rod 102, and the inner sleeve rod 102 is inserted into the outer sleeve 101 and the two ends are respectively from the outer sleeve 101 The front end of the inner sleeve rod 102 is connected to the ends of a plurality of elastic branches 103, and the front end of each elastic branch 103 is provided with a grinding block 104.

Example Embodiment
[0033] Example two
[0034] A preferred embodiment of driving the inner wall grinding device 10 is provided. The steel pipe inner and outer integrated automatic grinding system further includes a fixed pillar 50, the fixed pillar 50 is provided with a fixing bolt 501, and the internal thread on the fixing bolt 501 is connected to the inner thread on the inner sleeve rod 102. External thread engagement. The inner wall grinding device driving motor 402 drives the entire inner wall grinding device 10 to rotate clockwise, and at the same time makes the inner wall grinding device 10 move at a uniform speed in the axial direction of the steel pipe relative to the fixed bolt 501, so as to realize the grinding of the entire inner wall of the steel pipe.
Example Embodiment
[0035] Example three
[0036] In the first embodiment, the front end of the outer sleeve 101 of the inner wall grinding device 10 is provided with a V-shaped opening 105 for restraining and controlling the opening angle of the plurality of elastic branches 103. Since the processing technology of the V-shaped opening 105 is relatively complicated, the wall thickness of the outer sleeve 101 is also required. In order to facilitate the production and popularization of the inner wall grinding device 10, alternatives such as Figure 8 As shown, a V-shaped sleeve 106 is inserted into the front end of the outer sleeve 101 and fixed, instead of the V-shaped opening 105 in the first embodiment. Only the ordinary outer sleeve is combined with the V-shaped sleeve 106.
