[0002] Titanium alloy refers to a variety of alloy metals made of titanium and other metals. Titanium is an important structural metal developed in the 1950s. Titanium alloy has the characteristics of high strength, good corrosion resistance and high heat resistance. Milling cutters are needed in the process of titanium alloy processing.

[0003] Existing CNC machine tool milling cutters are usually connected with a single nut. In order to prevent the milling cutter from loosening, the tightening direction of the nut is deliberately made opposite to the rotation direction of the milling cutter handle. As a result, as the use time increases, the nut of the milling cutter will become tighter and tighter, making it difficult to disassemble and easily causing damage to the equipment. Therefore, a CNC milling cutter for processing titanium alloy is proposed. Utility Model Content

[0010] Furthermore, the outer surface of the liquid storage cylinder is fixedly connected to a liquid inlet pipe, and the outer surface of the liquid inlet pipe is provided with a plug.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The CNC milling cutter for processing titanium alloys has a limiting hole on the outer surface of the milling cutter head, cooperates with a first spring and a limiting block, performs preliminary limiting on the milling cutter head, and drives the extrusion sleeve to extrude the connecting block through the threaded sleeve, thereby increasing the stability of the milling cutter head limiting, thereby avoiding the use of nuts to fix the milling cutter, so that the milling cutter can be quickly removed after long-term use.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Please refer to Figure 1-Figure 5 The utility model provides a technical solution: a CNC milling cutter for processing titanium alloy, comprising a milling cutter head 1 and a shank 2, the left and right outer surfaces of the milling cutter head 1 are provided with limiting holes 3, the left and right outer surfaces of the shank 2 are provided with through grooves 4, the interiors of the two through grooves 4 are fixedly connected with fixing plates 5, the outer surfaces of the two fixing plates 5 located inside the shank 2 are fixedly connected with first springs 7, the outer surfaces of the first springs 7 away from the fixing plates 5 are fixedly connected with limiting blocks 8, the outer surfaces of the two fixing plates 5 are movably inserted with movable rods 6, the outer surfaces of the movable rods 6 located inside the shank 2 are fixedly connected with the limiting blocks 8, the other ends of the movable rods 6 are fixedly connected with the limiting blocks 8, the outer surface of the shank 2 is threadedly connected with a threaded sleeve 10, and the top outer surface of the threaded sleeve 10 is fixedly connected with an extrusion sleeve 11, in this embodiment, when the first spring 7 is in the initial state, the distance between the connecting block 9 and the surface of the shank 2 is equal to the distance between the limiting block 8 and the inner wall of the limiting hole 3, When the milling cutter head 1 needs to be installed, the milling cutter head 1 is inserted into the tool handle 2. When the top of the milling cutter head 1 contacts the limit block 8, the limit block 8 is squeezed to both sides, and the first spring 7 is deformed. When the limit block 8 contacts the limit hole 3, the limit block 8 is driven to be inserted into the limit hole 3 under the elastic force of the first spring 7, and then the extrusion sleeve 11 is inserted from bottom to top, and the threaded sleeve 10 is screwed on. When the threaded sleeve 10 drives the extrusion sleeve 11 so that the extrusion sleeve 11 is connected to the connection When the block 9 contacts, the connecting block 9 is squeezed inwardly, so that the limiting block 8 is close to the inside of the limiting hole 3, thereby limiting the milling cutter head 1. When disassembling, the threaded sleeve 10 is unscrewed, and the first spring 7 is reset to make the limiting block 8 move a distance to the right, and then the milling cutter head 1 is pulled downward. The milling cutter head 1 squeezes the limiting blocks 8 on both sides, and the milling cutter head 1 is removed, thereby avoiding the use of nuts to fix the milling cutter, so that the milling cutter can be quickly removed after long-term use.

[0022] A liquid storage cylinder 12 is fixedly connected to the top outer surface of the tool handle 2, and a connecting tube 13 is fixedly connected to the top inner surface of the tool handle 2. The connecting tube 13 is fixedly connected to the interior of the liquid storage cylinder 12. A conveying channel 14 is opened inside the milling cutter head 1. When the milling cutter head 1 is in use, the tool handle 2 is connected to the CNC machine, and the milling cutter head 1 contacts the titanium alloy for milling. During the milling process, the coolant in the liquid storage cylinder 12 enters the conveying channel 14 through the connecting tube 13 and falls onto the surface of the titanium alloy, which cools down the milling process and extends the service life of the milling cutter head 1.

[0023] A second spring 15 is fixedly connected to the top inner surface of the shank 2, and a connecting plate 16 is fixedly connected to the bottom outer surface of the second spring 15. In the present embodiment, when the milling cutter head 1 is inserted, the milling cutter head 1 squeezes the connecting plate 16 to compress the second spring 15. When the milling cutter head 1 is disassembled, the elastic force of the second spring 15 enables the milling cutter head 1 to be removed with only a little force.

[0024] The outer surface of the tool handle 2 is provided with internal thread teeth 17, and the interior of the threaded sleeve 10 is provided with external thread teeth 18 that are compatible with the internal thread teeth 17. In this embodiment, the external thread teeth 18 inside the threaded sleeve 10 cooperate with the internal thread teeth 17 to fix the threaded sleeve 10 and the tool handle 2, thereby fixing the extrusion sleeve 11.

[0025] The top outer surface and the bottom outer surface of the limit block 8 and the connecting block 9 are both smooth and inclined outer surfaces. In the present embodiment, by setting the limit block 8 with smooth and inclined top and bottom, it is convenient for the milling cutter head 1 to squeeze the limit block 8 when inserting and removing the milling cutter head 1, and by setting the connecting block 9 with smooth and inclined top and bottom, it is convenient to squeeze the connecting block 9 inward when the extrusion sleeve 11 is inserted.

[0026] The outer surface of the liquid storage cylinder 12 is fixedly connected to a liquid inlet pipe, and a plug is provided on the outer surface of the liquid inlet pipe. In this embodiment, the plug is opened to replenish coolant into the liquid storage cylinder 12 through the liquid inlet pipe.

[0027] Working principle: When the utility model is in use, when the milling cutter head 1 needs to be installed, the milling cutter head 1 is inserted into the shank 2. When the top of the milling cutter head 1 contacts the limit block 8, the limit block 8 is squeezed to both sides, and the first spring 7 is deformed. When the limit block 8 contacts the limit hole 3, the limit block 8 is driven to be inserted into the limit hole 3 under the elastic force of the first spring 7, and then the extrusion sleeve 11 is inserted from bottom to top, and the threaded sleeve 10 is screwed on. When the threaded sleeve 10 drives the extrusion sleeve 11 so that the extrusion sleeve 11 contacts the connecting block 9, , squeeze the connecting block 9 inward, so that the limit block 8 is close to the inside of the limit hole 3, thereby limiting the milling cutter head 1. When disassembling, unscrew the threaded sleeve 10, and the first spring 7 is reset to make the limit block 8 move one end distance to the right, and then pull the milling cutter head 1 downward, and the milling cutter head 1 squeezes the limit blocks 8 on both sides. With the elastic force of the second spring 15, the milling cutter head 1 can be removed by applying only a little force, thereby avoiding the use of nuts to fix the milling cutter, so that the milling cutter can be quickly removed after long-term use.

[0028] When the milling cutter head 1 is in use, the tool handle 2 is connected to the CNC machine, and the milling cutter head 1 contacts the titanium alloy for milling work. During the milling process, the coolant in the liquid storage cylinder 12 enters the delivery channel 14 through the connecting pipe 13 and falls onto the surface of the titanium alloy, thereby cooling the milling and extending the service life of the milling cutter head 1.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
