[0002] A milling cutter is a rotating tool with one or more teeth used for milling. When working, each tooth cuts off the excess of the workpiece intermittently in sequence. Milling cutters are mainly used to process planes, steps, grooves, forming surfaces and cut off workpieces on milling machines. When processing workpieces for different purposes, the milling cutter specifications used are also different. When the parameters of the workpiece are required to be high, high-precision milling cutters are often used.

[0003] However, the high-precision 6-edge milling cutters currently on the market need to be installed and disassembled before and after use, which makes it difficult to store the high-precision 6-edge milling cutters, and even causes the high-precision 6-edge milling cutters to be lost. This leads to a lack of placement ability for the high-precision 6-edge milling cutters, making it inconvenient for staff to classify the sizes of the high-precision 6-edge milling cutters, and is not conducive to the long-term use of the high-precision 6-edge milling cutters. Utility Model Content

[0008] Preferably, the sliding block is in contact with the inner wall of the limiting groove, the pull ring has a semicircular ring structure, and the pull ring is used to drive the movement of the limiting groove.

[0009] Preferably, the first magnetic block has opposite magnetic properties to the second magnetic block, and the first magnetic block is used to attract the second magnetic block.

[0010] Preferably, the size of the limiting slot is adapted to the size of the limiting block, the limiting slot is engaged with the limiting block, the balls are evenly distributed on the inner wall of the limiting slot, and the balls play a role in reducing friction.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] Embodiment 1, by Figure 1-4 The utility model includes a U-groove circular arc back angle high spiral high precision 6-blade milling cutter, including a cutter body 1, a cutter head 2 is fixedly connected to the bottom of the cutter body 1, a connecting block 3 is fixedly connected to the top of the cutter body 1, a shock absorbing ring 4 is sleeved on the outer side of the connecting block 3, the shock absorbing ring 4 is made of rubber material, and the shock absorbing ring 4 plays a role in reducing vibration, an accommodating groove 5 is provided on the outer side of the cutter body 1, the accommodating groove 5 is evenly distributed on the inner wall of the cutter body 1, the accommodating groove 5 is connected with the top of the cutter head 2, a limiting groove 8 is provided on the inner wall of the cutter body 1, a slider 6 is movably connected to the inner side of the limiting groove 8, the slider 6 is fitted with the inner wall of the limiting groove 8, the structure of the pull ring 7 is a semicircular ring structure, the pull ring 7 is used to drive the movement of the limiting groove 8, the outer side of the slider 6 is fixedly connected with a pull ring Ring 7, the inner wall of the knife body 1 and the outer side near the limiting groove 8 are provided with a connecting groove 9, the inner wall of the connecting groove 9 is elastically connected with a limiting block 10, the inner wall of the limiting block 10 is fixedly connected with a second magnetic block 14, the inner wall of the slider 6 is fixedly connected with a first magnetic block 12, the magnetic properties of the first magnetic block 12 and the second magnetic block 14 are opposite, the first magnetic block 12 is used to attract the second magnetic block 14, the inner wall of the slider 6 is provided with a limiting groove 11, the size of the limiting groove 11 is adapted to the size of the limiting block 10, the limiting groove 11 is engaged with the limiting block 10, the balls 13 are evenly distributed on the inner wall of the limiting groove 11, the balls 13 play a role in reducing friction, the inner wall of the slider 6 and the inner side of the limiting groove 11 are movably connected with the balls 13.

[0022] Working principle: When installing the high-precision 6-blade milling cutter, the staff first holds the cutter body 1 and aligns the connecting block 3 with the machine interface, installs the connecting block 3 to the machine interface and fixes it, and then pulls the pull ring 7. At this time, the pull ring 7 drives the slider 6 to move outward along the inner wall of the limit groove 8. At this moment, the limit groove 11 on the inner side of the slider 6 will squeeze the limit block 10. Under the action of the rolling of the ball 13, the friction between the limit block 10 and the limit groove 11 is reduced. At the same time, the limit block 10 will be subjected to the tension of the spring inside the connecting groove 9, so that the limit block 10 will move along the inner wall of the connecting groove 9, so that the limit block 10 overcomes the attraction between the first magnetic block 12 and the second magnetic block 14, until the limit groove 11 is separated from the limit block 10, thereby realizing the separation of the slider 6 and the limit groove 8, thereby not affecting the rotation of the cutter body 1, improving the practicality of the slider 6, and then starting the machine to complete the processing of the material;

[0023] When the high-precision 6-edge milling cutter is working, the impact of the machine's own vibration on the high-precision 6-edge milling cutter is offset by the cushioning effect of the cushioning ring 4, so that the high-precision 6-edge milling cutter has higher working accuracy. At the same time, the cut chips will move upward along the inner side of the receiving groove 5, avoiding the chips from adhering to the surroundings of the cutter head 2, thereby improving the accuracy of the high-precision 6-edge milling cutter.

[0024] When disassembling the high-precision 6-blade milling cutter, align the slider 6 with the limit groove 8 and insert it into the inner side of the limit groove 8. At this time, the first magnetic block 12 will attract the second magnetic block 14, so that the limit card block 10 stretches the spring to enter the inner side of the limit card slot 11, and then the limit card slot 11 is engaged with the limit card block 10, thereby realizing the relative fixation of the slider 6 and the limit groove 8. Then the connecting block 3 can be removed from the machine, and then the high-precision 6-blade milling cutter can be suspended by the pull ring 7, which is convenient for storing the high-precision 6-blade milling cutter and avoiding the loss of the high-precision 6-blade milling cutter. The ability to place the high-precision 6-blade milling cutter is improved, which is beneficial for the staff to classify the sizes of the high-precision 6-blade milling cutter and is beneficial for the long-term use of the high-precision 6-blade milling cutter.
