[0023] like Figure 1-3As shown, a lathe threading fixture of this utility model includes a support platform 1. Support legs 2 are provided at the four corners of the bottom of the support platform 1. The four support legs 2 are fixedly connected to each other by reinforcing rods 3. Guide rails 4 are provided on the front and rear upper surfaces of the support platform 1 along its length. Movable seats 5 are slidably connected to the upper surfaces of two guide rails 4. T-slots 7 are provided in the middle part of the upper surface of the guide rails 4 along its length. T-plates 13 are provided on both sides of the bottom of the movable seat 5 and are slidably connected to the T-slots 7. Through the cooperation between the T-plates 13 and the T-slots 7, the movable seat 5 plays an auxiliary support and limiting role, making the movable seat 5 more stable and reliable when moving. A cylinder 6 for driving the movable seat 5 is located at the middle of the right end of the upper surface of the support platform 1. The cylinder 6 is positioned between two guide rails 4. A motor 8 is located at the middle of the upper surface of the movable seat 5. A connecting shaft 9 is connected to the shaft of the motor 8. A sleeve 10 is slidably connected to the end of the connecting shaft 9. A threading head 11 is located at the end of the sleeve 10 away from the connecting shaft 9. A triangular chuck 12 concentric with the connecting shaft 9 is located at the middle of the left end of the upper surface of the support platform 1. The sleeve 10 and the threading head 11 are an integral structure. The sleeve 10 is hollow, and its inner diameter matches the outer diameter of the connecting shaft 9. By slidably connecting the sleeve 10 and the connecting shaft 9, the extension distance of the threading head 11 can be easily adjusted. A threaded hole 14 is provided on the side wall of the connecting shaft 9 away from the motor 8. An elongated hole 15 is provided on the side wall of the sleeve 10 along its length. A locking bolt 16 is threadedly connected between the elongated hole 15 and the threaded hole 14. The diameter of the nut of the locking bolt 16 is larger than the diameter of the elongated hole 15. The sleeve 10 is easy to disassemble and install through the cooperation between the threaded hole 14, the elongated hole 15 and the locking bolt 16, which facilitates the replacement of the threaded end 11.

[0024] The working principle of this lathe threading fixture is as follows: When in use, the workpiece is fixed on the triangular chuck 12, the cylinder 6 is started, which pushes the movable seat 5 to one side of the triangular chuck 12, so that the threading head 11 is fitted onto the workpiece. The motor 8 is started, which causes the connecting shaft 9 to drive the sleeve 10 to rotate, thus realizing the threading of the workpiece. The whole process is highly automated, which greatly reduces the labor intensity of workers and greatly improves work efficiency. The finished product is of good quality and is especially suitable for batch processing, ensuring production needs. It is 20 times more efficient than manual threading and 2-4 times more efficient than threading machines. This fixture can also be used for the repair of old bolts.

[0025] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
