It should be understood that the data used in this way can be interchanged where appropriate for the embodiments of the present invention described herein. In addition, similar terms such as "including" and "having" mean that in addition to those contents already listed in "including" and "having", other contents that have not been listed may also be "included" and "having"; for example, a process, method, system, product or device that may include a series of steps or units is not necessarily limited to those steps or units that have been clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or devices.

[0021] Due to the angle of the drawing, some components may not be drawn, but their positions and connection relationships can be partially understood based on the text.

[0022] like Figure 1As shown, the utility model is a tool for turning long cantilever thin-walled parts, including a core rod 1, a front clamping portion and an axial positioning block 2 are provided at the front end of the core rod 1, a rear clamping portion is provided at the rear end of the core rod 1, and positioning surfaces 7 and a fixing mechanism are evenly distributed on the core rod 1.

[0023] The front clamping part and the rear clamping part are used to install the core rod 1 on the lathe. The front clamping part is a front positioning plate 8, which is circular; the rear clamping part is a rear positioning ring 9, and the rear positioning ring 9 has a rear positioning hole 9-1 in the middle.

[0024] A three-jaw chuck is installed at the front end of the lathe, and an ejector is installed in the tailstock at the rear end of the lathe; the three-jaw chuck jaws contact the front positioning plate 8, and the ejector presses against the rear positioning hole 9-1, completing the installation of the core rod 1 and the lathe.

[0025] In this embodiment, two positioning surfaces 7 are evenly distributed on the core rod 1, so that two long cantilever thin-walled parts 11 can be processed simultaneously, thereby improving work efficiency and achieving rotation stability.

[0026] The positioning surfaces 7 are arranged linearly, and weight-reducing grooves 10 are provided between the positioning surfaces 7 .

[0027] The fixing mechanism is a fixing screw 5, and screw holes are provided on both sides of the positioning surface 7. A process waist groove is provided on both sides of the long cantilever thin-walled part 11, and the fixing screw 5 is passed through the process waist groove and screwed into the screw hole.

[0028] In order to support the middle part of the long cantilever thin-walled part 11, a support groove is provided in the middle of the core rod 1, in which a support block 3 is installed through an adjusting screw 6. An adjustment groove is provided in the support block 3 for sliding adjustment of the support block. The support block 3 is provided with a screw hole.

[0029] In order to further increase the support for the long cantilever thin-walled parts 11, the rear clamping part is threadedly connected with a support bolt 4. Since the support bolt 4 has an adjustable ability, it has a higher fit with the long cantilever thin-walled parts 11.

[0030] In order to further reduce the weight of the core rod 1 , weight-reducing holes are radially opened at equal distances on the core rod 1 .

[0031] The working process of this utility model is as follows:

[0032] Clamp the core rod 1 on the lathe (one end is positioned and pressed with a three-jaw chuck, and the end with the thimble is tightened with the thimble of the lathe tailstock); use a lever dial indicator to suck it into a fixed position on the lathe, rotate the lathe spindle, align the head of the lever dial indicator with the position of the tooling axis, observe the jump of the dial indicator, and adjust the tooling position.

[0033] like Figure 2As shown, the long cantilever thin-walled part 11 is installed on the core rod 1, the inner side of the long cantilever thin-walled part 11 is tightly against the positioning surface 7, and the end face of the long cantilever thin-walled part 11 is tightly against the axial positioning block 2. Then slide the support block 3 against the middle of the long cantilever thin-walled part 11, tighten the adjusting screw 6 and the fixing screw 5, and rotate the support bolt 4 to press against the end of the long cantilever thin-walled part 11 to complete the clamping and start processing.

[0034] It is understood that the above embodiments are merely exemplary embodiments for illustrating the principles of the present invention, and the present invention is not limited thereto.
