[0020] Example 1:
[0021] like Figs. 1-3 As shown, a clamping and positioning assembly for tubular parts used in machining includes a base plate 1 and a circular rotating plate 2 movably disposed on the top surface of the base plate 1. An inner clamping assembly 3 and an outer clamping assembly 4 are mounted on the top surface of the circular rotating plate 2. The inner clamping assembly 3 includes a mounting ring 32 and three inner abutting rods 33 that slide radially and are evenly distributed on the mounting ring 32 to abut against the inner ring of the tubular part. A vertical mounting plate 31 is provided on the top surface of the circular rotating plate 2. A mounting column is rotatably mounted on one side of the mounting plate 31. Three adjusting arc blocks 34, which cooperate with the corresponding inner abutting rods 33, are evenly distributed on the outer side of the suspended end of the mounting column. The arc surface of the adjusting arc blocks 34 is a convex surface. The outer clamping assembly 4 includes a mounting ring 42 and three outer abutting rods 43 that slide radially and are evenly distributed on a convex plate on one side of the mounting ring 42 to abut against the outer ring of the tubular part. A vertical mounting plate 41 is provided on the top surface of the circular rotating plate 2, and a ring is fixedly sleeved on the outer side of the mounting plate 41. The guide plate has an annular guide plate with an adjusting ring plate 45 rotatably mounted on one side. Three adjusting arc blocks 44, each corresponding to an outer abutment rod 43, are evenly distributed within the inner ring of the adjusting ring plate 45. The arc surface of the adjusting arc block 44 is concave. Return springs for resetting are fitted onto the rods of both the outer abutment rod 43 and the inner abutment rod 33. A transmission component is located at the top of the circular rotating plate 2 to control the movement of the adjusting arc blocks 34 and 44. The inner clamping assembly 3 and the outer clamping assembly 4 allow for the selection of different clamping components at the end of the tubular component according to the processing position. The three-point positioning of the clamping components provides better support for laterally processed tubular components. The adjusting arc blocks 34 and 44 can clamp the corresponding position at the end of the tubular component and can also clamp tubular components within a certain size range, thus broadening its applicability.

The straight line angle between the center point of the mounting ring one 32 and the center point of the mounting ring two 42 to the center point of the circular rotating plate 2 is ninety degrees, and the vertical distance between the end part of the adjusting motor shell and the axis of the circular rotating plate 2 is greater than the outer ring radius of the mounting ring two 42, so that the outer clamping assembly 4 and the inner clamping assembly 3 will not affect each other when the external machining tool extends along the axis direction of the tubular column-shaped part. The pull plate 6 is fixedly arranged on the circumferential side of the circular rotating plate 2, the top surface of the bottom plate 1 is provided with positioning points for positioning the position of the pull plate 6, and the straight line angle between the two positioning points to the center point of the circular rotating plate 2 is ninety degrees, so as to conveniently adjust the corresponding clamping assembly to clamp the end part of the tubular column-shaped part.
