The transition member 60 is in a rectangular frame structure, and the transition member 60 is located in a cavity surrounded by the two first vertical plates 12 and the two second vertical plates 22. The transition part 60 is pivoted with the first frame 10, and specifically, two first rotating shafts 31 vertically penetrate through the first vertical plate 12 and the transition part 60 respectively, so that the transition part 60 is pivoted with the first frame 10; the second frame 20 is pivotally connected to the transition member 60, and specifically, the two second rotating shafts 32 vertically penetrate through the second vertical plate 22 and the transition member 60, respectively, so that the second frame 20 is pivotally connected to the transition member 60. Also, the pivot axis o1 of the transition member 60 relative to the first frame 10 is perpendicular to the pivot axis o2 of the second frame 20 relative to the transition member 60. In this way, the second frame 20 can be adjusted in spatial attitude by pivoting itself with respect to the transition member 60 and pivoting the transition member 60 with respect to the first frame 10.
The workpiece 100 is used for being mounted on the holding member 70, the lower end of the holding member 70 is formed with a stud 73, a threaded hole is opened on the bottom plate 21 of the second frame 20, and the stud 73 is screwed into the threaded hole so that the holding member 70 is fixed on the bottom plate 21 of the second frame 20; the holding member 70 is substantially sleeve-shaped, that is, a mounting hole 71 is opened at the middle part of the holding member 70, and the structure of the mounting hole 71 is matched with the outer peripheral surface of the workpiece 100, that is, when the outer peripheral surface of the workpiece 100 is a polygonal cylindrical surface, a limit plane 72 is formed at the hole wall of the mounting hole 71 of the holding member 70, so that the workpiece 100 cannot rotate relative to the holding member 70 after the workpiece 100 is inserted into the mounting hole 71.
As is apparent from the above description, since the holding member 70 is attached to the bottom plate 21 of the first frame 10 and the workpiece 100 is fitted into the attachment hole 71 of the holding member 70, the spatial attitude of the holding member 70 can be adjusted by the second frame 20 pivoting with respect to the transition member 60 and the transition member 60 pivoting with respect to the first frame 10.

As shown in fig. 3, when the transition member 60 is adjusted by pivoting to a spatial angle such that the holding member 70 and the workpiece 100 conform to the direction, the two first positioning bolts 412 are screwed against the transition member 60, thereby restricting the transition member 60 from pivoting to be held at the adjusted angle.
When the second frame 20 is adjusted by pivoting to a spatial angle such that the holding member 70 and the workpiece 100 conform to the direction, the two second positioning bolts 422 are screwed against the transition member 60, thereby restricting the second frame 20 from being held upright at the adjusted angle.
By adjusting the two positioning components, the workpiece 100 is adjusted to a desired spatial attitude.
The first position adjustment member 51 includes a first adjustment bolt 511 passing through the first vertical plate 12 and a first locking nut 512 sleeved on the first adjustment bolt 511, the first adjustment bolt 511 is screwed to push the transition member 60 to adjust the position of the transition member 60 in the front and rear directions, and then the first locking nut 512 is screwed to prevent the first adjustment bolt 511 from being loosened. The second position adjusting member 52 includes a second adjusting bolt 521 passing through the second vertical plate 22 and a second locking nut 522 sleeved on the second adjusting bolt 521, and the position of the transition member 60 in the left and right directions is adjusted by screwing the second adjusting bolt 521 so that the second adjusting bolt 521 pushes against the transition member 60. Then, the second lock nut 522 is tightened to prevent the second adjustment bolt 521 from being loosened. In this way, the positions of the holding member 70 and the workpiece 100 can be adjusted by the first position adjustment member 51 and the second position adjustment member 52 so that the position of the workpiece 100 meets the requirements.
As shown in fig. 4, after the spatial attitude and position adjustment of the workpiece 100 is completed, the inner hole of the workpiece 100 is strictly aligned with the grinding stone 200, and the grinding stone 200 is inserted into the inner hole of the workpiece 100 to grind the inner hole of the workpiece 100 by the rotational and axial feed motion.
