[0024] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] With reference to Figures 1-2 The present application provides an embodiment: a square shoulder milling replaceable tool head, comprising a tool body 1, the bottom of the tool body 1 is fixedly connected with an intermediate column 4, the tool body 1 has a fixed position effect on the intermediate column 4. The outside of the intermediate column 4 is fixedly connected with a threaded ring 2, and the threaded ring 2 is arranged to facilitate the replacement of the tool head. A plurality of sliding grooves 5 (as shown in the accompanying drawings) are formed in the inside of the intermediate column 4, and when the plurality of sliding grooves 5 are connected with the external structure, the plurality of movable balls 6 are spirally extruded, so that a small amount of lubricating oil stays in the inside of the sliding groove 5, thereby enabling the lubricating oil to slowly act on the threaded ring 2, so that the addition of lubricating oil does not cause excessive stickiness. Figure 2

[0026] The inner walls of the plurality of sliding grooves 5 are movably connected with the movable balls 6, and in the process of spiraling, the movement of the plurality of movable balls 6 enables the lubricating oil to be in a flowing state. The outside of the plurality of movable balls 6 is movably connected in the inside of the threaded ring 2, and the position change of the movable balls 6 drives the lubricating oil to communicate between the outside of the threaded ring 2 and the inside of the sliding groove 5.

[0027] With reference to Figure 1 The top of the tool body 1 is fixedly connected with a machining assembly for cutting machining, and the machining assembly comprises a contact head 8, the outside of the contact head 8 is fixedly connected at the top of the tool body 1, and the tool body 1 has a supporting and fixed position effect on the contact head 8. A plurality of small holes are formed in the inner wall of the contact head 8, and the plurality of small holes are arranged to fix the positions of other components. The inner walls of the plurality of small holes are threadedly connected with screws 10, and the screws 10 are used to fix the positions of the components more stably. The other ends of the plurality of screws 10 are threadedly connected with blades 9, so that the positions of the blades 9 and the contact head 10 can be detachably fixed, and when the blades 9 are detached, the screws 10 can be untwisted in the opposite direction. The outside of the blade 9 is in contact with the outside of the contact head 8, and after the blade 9 is fixed in position, a part of the blade 9 is in contact with the inner wall of the contact head 8, so that the blade 9 can be stable during work.

[0028] With reference to Figures 3-4 The bottom of the tool body 1 is fixedly connected with a rubber ring 3, and the rubber ring 3 is made of a ductile material. The inner wall of the rubber ring 3 is slidably connected with the outside of the threaded ring 2, one end of the rubber ring 3 is fixed at the bottom of the tool body 1, and the other end of the rubber ring 3 is deformed under the extrusion of the external structure. A plurality of channels 7 (as shown in the accompanying drawings) are formed in the inner wall of the rubber ring 3, and the plurality of channels 7 are arranged to communicate between the outside of the threaded ring 2 and the inside of the sliding groove 5. Figure 3 ​), the rubber ring 3 can extrude the lubricating oil from the inner wall of the plurality of channels 7 when deformed, the other end of the plurality of channels 7 is communicated with each other, so that the lubricating oil can flow along the outside of the thread ring 2, thereby forming a lubricating effect.

[0029] Working principle: when the replaceable tool bit is connected with the external structure, the rubber ring 2 touches the external structure, and the rubber ring 2 is extruded, so that the lubricating oil can flow along the channel, and when the screw continues to spiral, the thread extrudes the plurality of movable balls 6, so that the plurality of movable balls 6 are pressed down and then pushed by the lubricating oil to present a convex state, thereby driving the lubricating oil to change position, so that a small amount of lubricating oil stays inside the sliding groove 5, so that the lubricating oil can slowly act on the thread ring 2, so that the added lubricating oil does not cause the paste, and in the spiral process, the movement of the plurality of movable balls 6 makes the lubricating oil in a flowing state, regularly checks and maintains the threaded connection, timely removes rust and applies an appropriate amount of anti-rust oil or lubricating oil, so as to prolong the service life of the tool bit and keep its good working condition.

[0030] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the protection scope of the present application.
