[0010] The above technical scheme has the following beneficial effects:

[0011] The utility model has simple structure, the circular truncated cone of conical locating disc is inserted into thin-walled cylinder for supporting, which is convenient for clamping thin-walled cylindrical aluminum parts and not easy to deform, and the circular truncated cone of conical locating disc can be used for different hole diameters, thereby expanding the range of use.

[0012] The small-diameter end bottom surface of the circular truncated cone is provided with a clamping part reserved for repairing the tool, which is convenient for clamping during subsequent repair of the circular truncated cone.

[0013] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the structure of specific embodiment 1;

[0015] Figure 2 for Figure 1 Side view.

[0016] In the attached diagram, 1 is a truncated cone, 2 is a clamping part, and 3 is a mounting groove. Detailed Implementation Specific Implementation

[0017] See Figure 1 and Figure 2 As shown, a clamping fixture for turning thin-walled cylindrical aluminum parts includes a worktable and a lathe mounted on the worktable. The lathe is equipped with an ejector mechanism and a conical positioning plate. The conical positioning plate has a truncated cone 1, and the bottom surface of the large-diameter end of the truncated cone 1 has a mounting groove 3, which is a conical center hole. In this specific embodiment, the mounting groove 3 is located at the center of the bottom surface of the large-diameter end of the truncated cone, and the mounting groove 3 is used to mount the conical positioning plate on the ejector mechanism. The truncated cone 1 is used to mate with the inner wall of the thin-walled cylindrical workpiece to be processed. The thin-walled cylindrical workpiece to be processed is an aluminum alloy part, an aluminum part, or a large-diameter cylindrical workpiece. The lathe inserts the truncated cone 1 of the conical positioning plate into the inner wall of the thin-walled cylindrical workpiece to be processed, thereby supporting the circumference of the thin-walled cylindrical workpiece to be processed and preventing deformation of the thin-walled cylindrical workpiece due to partial stress.

[0018] The small-diameter end of the truncated cone 1 is provided with a clamping part 2 for the repair tooling. The clamping part 2 is a truncated cone. Due to long-term contact with the workpiece, the tapered part of the truncated cone 1 is worn, which affects the accuracy. Therefore, it is necessary to repair the tapered part of the truncated cone of the conical positioning plate. During the repair, the lathe clamps and aligns the truncated cone at the small end of the truncated cone in the clamping part 2.

[0019] The working principle of this utility model:

[0020] By installing a conical positioning plate on the ejector mechanism on the worktable, and then inserting the conical positioning plate into the thin-walled cylinder to be processed, the conical positioning plate is supported on the inner wall of the thin-walled cylinder by the truncated cone of the conical positioning plate. This effectively avoids the deformation of the workpiece caused by directly clamping it on part of the outer wall of the thin-walled cylinder by using a chuck mechanism, and improves the processing accuracy of the thin-walled cylinder parts.
