[0002] The methods for turning a cone on a common lathe include: 1. Rotating the small slide method; 2. Offset tailstock method; 3. Profiling method (profiling method); 4. Wide blade turning method; 5. Reaming internal cone method. When turning a shorter cone, the rotating small slide method is generally used. When turning, just rotate the small slide to a certain angle according to the requirements of the workpiece so that the motion trajectory of the turning tool is parallel to the cone element line.
[0003] This method is simple to operate, has a wide adjustment range, and can ensure a certain degree of accuracy. However, when there are two or more cones on a workpiece, the small slide needs to be rotated multiple times. Sometimes the small slide is interfered with by the lathe chuck or the lathe tailstock, affecting the processing. In addition, the fastening nut needs to be loosened and tightened each time the small slide is moved, which reduces the processing efficiency.
[0004] Based on the above problems, there may already be technical means in the current technology to solve the above technical solutions. This case intends to provide an alternative or replacement technical means. Utility Model Content

[0018] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
[0019] Example
[0020] See also Figure 1-3 , the utility model provides a technical solution: a lathe turning tool for processing a conical surface;
[0021] This case aims to provide a lathe tool for machining conical surfaces that is convenient for manual feeding. The existing small slide workpiece is easily interfered with by the lathe chuck or the lathe tailstock, which affects the machining and has low machining efficiency.
[0022] Based on the above problems, the components in this case include a tool holder 1, a tool seat 2 is inserted into one side of the tool holder 1, and a plurality of clamping bolts 3 are provided at the connection between the tool holder 1 and the tool seat 2. The tool seat 2 is configured as a whole in a cylindrical shape, and an end cover 4 is connected to one side of the tool seat 2 by bolts. A screw rod 5 passes through the middle part of the end cover 4, and a cavity is provided inside the end cover 4. A first thrust bearing 6 is provided inside the cavity. A second thrust bearing 7 is provided on one side of the end cover 4, and the screw rod 5 is rotatably connected to the first thrust bearing 6 and the second thrust bearing 7 respectively;
[0023] A knife rod 8 is inserted into the other side of the knife seat 2, and a screw nut 9 is connected to one end of the knife rod 8 inserted into the knife seat 2. The screw nut 9 is threadedly connected to the screw rod 5. A hand wheel 10 is inserted into one side of the screw rod 5. A locking nut 11 is threadedly connected to the connection between the screw rod 5 and the hand wheel 10. A knife head 12 is provided on one side of the knife rod 8;
[0024] It should be noted that when the cutter head 12 is installed, the end cover 4 is first fixed to one side of the cutter seat 2 with a screw, and then the handwheel 10 is inserted into one end of the screw rod 5, and the lock nut 11 can be used to limit the position of the handwheel 10. A pin hole is provided on one side of the screw rod 5, and a pin that matches the pin hole is inserted on the outside of the handwheel 10. When the operator rotates the handwheel 10 through the handle 13, the screw rod 5 can be driven to rotate. Then the operator inserts the cutter rod 8 and the screw nut 9 into the inside of the cutter seat 2, and the screw nut 9 is threadedly connected to the screw rod 5, and at the same time, the guide groove at the bottom of the cutter rod 8 is plugged into the guide block 16;
[0025] When a lathe is required to turn a shorter conical workpiece, the tool holder 2 will be fixed to the lathe tool holder 1 by a plurality of clamping bolts 3, and the workpiece turning operation can be performed. When the position of the cutter head 12 needs to be adjusted, the operator can drive the screw rod 5 to rotate by using the handle 13 and the hand wheel 10. Since the screw rod 5 is threadedly connected to the screw rod nut 9, the tool rod 8 and the cutter head 12 can be pushed to move along the guide groove. After moving to the expected position, the position of the tool rod 8 and the cutter head 12 can be fixed by the locking bolt 17. The first thrust bearing 6 and the second thrust bearing 7 are used to ensure that the screw rod 5 can rotate normally when the screw rod 5 receives the reaction force generated by the thread when the cutter rod 8 is adjusted.
[0026] A first oiling nozzle 14 is provided on the top of the tool holder 2, and a second oiling nozzle 15 is provided on the top of the end cover 4, so that the operator can inject lubricant into the first thrust bearing 6 and the second thrust bearing 7 respectively, thereby keeping the first thrust bearing 6 and the second thrust bearing 7 running smoothly.
[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
