[0034] Please refer to Figures 1 to 8 The automatic oiling mechanism for threading in the figure mainly designs an oil storage tank 1, an adapter 2, a linkage frame 3, a first clamp 4, a second clamp 5, a tension spring 6, a positioning pin 7, and an oil outlet pipe 83 structure. In this case, the adapter 2 is used to achieve the connection between the dynamic and static components, and the clamp is used to link with the threading die head 10 to ensure stable oil discharge.

[0035] The main function of the oil storage tank 1 in the figure is to store lubricating liquid. Its shape can be designed to match the original frame of the threading machine. Specifically, an inwardly recessed groove 11 is designed in the middle of the bottom, which is convenient for the original frame to be inserted, thereby ensuring the overall stable fixation of the oil storage tank 1.

[0036] The adapter 2 in the figure is a component with two ends that can rotate relative to each other. It is a standard component, that is, one end can rotate relative to the other end, so that one end can be fixedly mounted on the oil pipe 81, and the other end can be mounted on the linkage frame 3 and rotate in conjunction with the linkage frame 3, so that the adapter 2 and the linkage frame 3 can maintain relative rotational cooperation, and the normal delivery of the lubricating fluid is maintained through such a design. As shown in the figure, the oil storage tank 1 is designed with a switch 84 and an oil pump and other conventional delivery mechanisms. The oil pump is connected to the oil storage tank 1 and the oil pipe 81 respectively, and the switch 84 controls the opening and closing of the oil pump. In addition, conventional components such as connectors 82 can be added. For example, the two horizontal and vertical oil pipes 81 in the figure are connected. Through the combination of the above components, the oil storage tank 1 is connected to the linkage frame 3 through the oil pipe 81 and the adapter 2 to ensure that the lubricating liquid, i.e., the lubricating oil, is delivered to the oil outlet pipe 83. In this way, when the switch 84 is turned on, the lubricating liquid is delivered to the oil outlet pipe 83 through the oil pump, the oil pipe 81, the connecting pipe, and the adapter 2. Since the adapter 2 uses mutually rotating components, the rotating threading die head 10 does not affect the normal delivery of the lubricating liquid. The oil outlet pipe 83 can be refueled at a fixed point at the cutting position, and there is no need to manually refuel the tap during the working process.

[0037] The main structure of the linkage frame 3 in the figure adopts a Y-shaped design, with its outward end being straight and the middle being a circular structure, thus forming three straight walls 31, two of which are used to install the first clamp 4, and the third straight wall 31 is used to install the second clamp 5, so that the first clamp 4 and the second clamp 5 are evenly spaced and arranged on a circle with the axis of the linkage frame 3 as the center. In order to facilitate the installation of the first clamp 4, a plurality of pin holes 9 are designed longitudinally aligned along the center position of the straight wall 31, and the first clamp 4 is also designed with a pin hole 9 at the corresponding position, so that the first clamp 4 can be firmly fixed on the straight wall 31 by using a pin shaft and its installation position can be adjusted at any time according to the diameter of the different threading die heads 10. In order to facilitate the installation of the second clamping component 5, it is mainly designed with a positioning pin 7, a tension spring 6, and a placement groove 311; wherein the placement groove 311 is used to place the positioning pin 7 and the tension spring 6, the positioning pin 7 is used for the limited sliding of the second clamping component 5, and the tension spring 6 is used to pull the second clamping component 5 so as to always clamp the threading die head 10. As shown in the figure, one end of the positioning pin 7 is installed on the wall at the middle position of the linkage frame 3, and the other end passes through the second clamping component 5 and is installed on the wall of the straight wall 31 at the corresponding position; one end of the tension spring 6 is installed on a hanging plate 312 opposite to the second clamping component 5, and the other end is hung on the second clamping component 5.

[0038] The first clamping member 4 in the figure is designed with two symmetrically arranged clamping ends 41 at the position matching with the straight wall 31 so as to fit the straight wall 31 of the linkage frame 3, and at the same time, a circular arc surface 42 is designed at the position matching with the round tube to form a step structure, which is convenient for clamping the pipe. In order to facilitate installation, a pin hole 9 structure is designed at the step position to ensure that the first clamping member 4 is fixedly matched with the straight wall 31 of the linkage frame 3. Through the above design, the first clamping member 4 can be fixed on the straight wall 31 of the linkage frame 3 and remain motionless, and its position on the straight wall 31 can be adjusted accordingly according to the diameter of different threading dies 10.

[0039] The main structure of the second clamping member 5 in the figure is similar to that of the first clamping member 4, and is also designed with an arc surface 42 and a step structure, which is convenient for clamping the pipe. The second clamping member 5 is uniquely designed with a push piece 51, which is an L-shaped structure. At the same time, a straight groove 52 structure is designed on the straight wall 31 at this position, which is convenient for the push piece 51 to move back and forth along the straight groove 52, thereby realizing the sliding cooperation between the second clamping member 5 and the linkage frame 3, that is, when it is necessary to clamp the threading die 10, the push piece 51 is pulled outward, and the second clamping member 5 can be threaded on the threading die 10 under the pullback of the tension spring 6.

[0040] The tension spring 6 in the figure is an existing component, which is sleeved on the positioning pin 7 and provides an inward pulling force to the second clamp 5, so that the second clamp 5 can clamp the threading die head 10. One end of the tension spring 6 is fixed on the circular wall 32 of the linkage frame 3, as shown in the position of the hanging plate 312 in the figure, and the other end is hung on the second clamp 5.

[0041] The positioning pin 7 in the figure is a conventional round shaft structure, one end of which is mounted on the circular wall 32 of the linkage frame 3, and the other end is mounted on the straight wall 31 of the linkage frame 3. The second clamping member 5 can slide and position in the above-mentioned straight groove 52 through the positioning pin 7.

[0042] The oil outlet pipe 83 in the figure is a conventional hose structure, which transports the lubricating fluid to the location that requires lubrication.

[0043] The threading machine in the figure is different from the existing threading machine in that the above-mentioned automatic oiling mechanism is installed.
