At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0023] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description.

[0027] A tungsten steel milling cutter for high wear resistance machining comprises a tungsten steel milling cutter body 1, the upper end surface of the tungsten steel milling cutter body 1 is fixedly connected with a connecting rod 2, the outer side of the connecting rod 2 is sleeved with a collar 3, the inner ring of the collar 3 is provided with a plurality of equal-sized card grooves 4, the inner sides of the card grooves 4 are all fixedly connected with arc-shaped magnetic blocks 5, the bottom of the collar 3 is fixedly connected with a protective sleeve 6, the inner side of the connecting rod 2 is provided with a first groove 8 with equal groove diameters, the inner side of the first groove 8 is provided with a first spring 9, the inner side of the first groove 8 is slidably connected with a first magnetic block 10 with one side arranged in an arc shape, the inner side of the connecting rod 2 is provided with a second groove 11 with the same groove diameter, the inner side of the second groove 11 is provided with a second spring 12, the inner side of the second groove 11 is slidably connected with a second magnetic block 13 with one side arranged in an arc shape, and the end of the connecting rod 2 away from the tungsten steel milling cutter body 1 is fixedly connected with a limited position mounting block 14.

[0028] The size of the groove diameter of the first groove 8 is equal to the size of the groove diameter of the second groove 11. The first magnetic block 10 and the second magnetic block 13 are arranged in an equiangular array with the same center. This arrangement allows the first magnetic block 10 and the second magnetic block 13 to be engaged with the groove 4; one side of the first magnetic block 10 that is arranged in an arc shape is engaged with the inner side of the groove 4, and one side of the first magnetic block 10 that is arranged in an arc shape is in contact with the arc-shaped magnetic block 5. This arrangement allows the protective sleeve 6 to be sleeved on the outer side of the tungsten steel milling cutter body 1 through the engagement of the first magnetic block 10 with the groove 4. The protective sleeve 6 can be used when the high wear-resistant machine stops processing. The tungsten steel milling cutter body 1 is protected; the two ends of the first spring 9 are fixedly connected to the inner wall of the first groove 8 and the first magnetic block 10 respectively, and the two ends of the second spring 12 are fixedly connected to the inner wall of the second groove 11 and the second magnetic block 13 respectively. This arrangement enables the installation of the first spring 9 and the second spring 12; a cleaning ring 7 is fixedly connected to the bottom of the inner wall of the protective sleeve 6, and the cleaning ring 7 is sleeved on the outside of the tungsten steel milling cutter body 1. The protective sleeve 6 is sleeved on the outside of the tungsten steel milling cutter body 1. This arrangement allows the cleaning ring 7 to act on the tungsten steel milling cutter body 1 to clean the tungsten steel milling cutter body 1 to a certain extent.

[0029] Working process: the collar 3 is sleeved on the outside of the connecting rod 2, the first magnetic block 10 is engaged with the slot 4, and the first magnetic block 10 is fitted with the arc-shaped magnetic block 5, so that the protective sleeve 6 is sleeved on the outside of the tungsten steel milling cutter body 1. The protective sleeve 6 can protect the tungsten steel milling cutter body 1 when the high wear-resistant machine stops processing, and can also reduce the adhesion of external dust. The first magnetic block 10 can be separated from the arc-shaped magnetic block 5 by pushing the collar 3 with force. In this process, the first spring 9 will be compressed by the first magnetic block 10, and the first magnetic block 10 slides on the inside of the first groove 8, so that the protective sleeve 6 and the collar 3 slide, and the protective sleeve 6 drives the cleaning ring 7 to slide, so that the cleaning ring 7 acts on the tungsten steel milling cutter body 1, and cleans the tungsten steel milling cutter body 1 to a certain extent. When the high wear-resistant machine stops processing, the protective sleeve 6 can protect the tungsten steel milling cutter body 1.

During this process, the second spring 12 will be compressed by the second magnetic block 13 first, and the second magnetic block 13 slides inside the second groove 11. When the arc-shaped magnetic block 5 is fitted with the second magnetic block 13, the second spring 12 generates a reaction force on the second magnetic block 13 according to its own elasticity, so that the second magnetic block 13 can be better engaged with the inner side of the slot 4, so that the protective sleeve 6 will not affect the use of the tungsten steel milling cutter body 1, and the tungsten steel milling cutter processed by high wear resistance machining is installed on the high wear resistance machine through the limit mounting block 14.
