[0002] A milling cutter is a rotating cutting tool with one or more cutting teeth used for milling. During operation, each cutting tooth cuts off the excess material of the workpiece in sequence and intermittently. Milling cutters are mainly used to machine planes, steps, grooves, shaped surfaces and cut off workpieces on milling machines. The femoral support is machined by a milling cutter.

[0003] Chinese Patent Publication No. CN215746634U discloses a rotary high-precision milling cutter for femoral support processing. This patent discloses a technical solution to improve service life and reduce usage costs, solving the problem that existing femoral support requires high precision and is made of hard material, and the milling cutter is prone to breakage and damage during processing. Moreover, once wear occurs, the entire milling cutter needs to be replaced, which is costly.

[0024] Please see Figures 1 to 5 In this embodiment, a milling cutter for bracket processing includes a bracket processing milling cutter body 1, a cover 2 and a cutter body 16 disposed on the bracket processing milling cutter body 1, and a sponge cover 5 placed on the inner peripheral wall of the cover 2.

[0025] Two fixing plates 3 are fixedly connected to the bottom surface of the cover 2. Connecting plates 6 are fixedly connected to the left and right inner walls of the sponge cover 5. Positioning grooves 13 are opened on the top surface of the two fixing plates 3. Positioning blocks 7 with one end extending into the positioning groove 13 are fixedly connected to the bottom surface of the two connecting plates 6. Mounting grooves 10 are opened on the opposite side of the two fixing plates 3. A clearance hole 21 is opened on the top surface of the sponge cover 5. A connecting ring 17 is fixedly connected inside the clearance hole 21. The blade body 16 passes through the connecting ring 17.

[0026] The positioning block 7 and the positioning groove 13 are slidably connected, the connecting plate 6 and the fixing plate 3 are fitted together, and the blade body 16 and the connecting ring 17 are fitted with a clearance.

[0027] It should be noted that the support machining milling cutter body 1 is a conventional device known to the public in the prior art, and its specific structure and working principle will not be described in detail in this article.

[0028] Specifically, the sponge cover 5 is pushed into the interior of the cover body 2, the blade body 16 passes through the clearance hole 21, the sponge cover 5 is pushed to fit the cover body 2, the positioning block 7 is inserted into the interior of the positioning groove 13, and the sponge cover 5 is restricted by the sliding connection between the positioning block 7 and the positioning groove 13 to improve the stability of the sponge cover 5.

[0029] In this embodiment, both fixing plates 3 are equipped with fixing components, including telescopic rods 11. The telescopic rods 11 are fixedly connected to the inside of the mounting groove 10. A baffle 20 is fixedly connected to the top surface of the telescopic rods 11. Springs 12, which are fixedly connected to the baffle 20 and the mounting groove 10 respectively, are fitted on the outer peripheral wall of the telescopic rods 11. Fixing holes 14 are opened on the bottom surface of both positioning blocks 7. A fixing rod 15 with one end extending into the fixing hole 14 is fixedly connected to the top surface of the baffle 20. A support groove 9 is opened inside the fixing plate 3. A support plate 8 with one end extending into the support groove 9 is fixedly connected to the side of the baffle 20 near the support groove 9.

[0030] Among them, the support plate 8 is an L-shaped plate, the support plate 8 and the support groove 9 are slidably connected, the fixed rod 15 and the fixed hole 14 are clearance fit, the telescopic rod 11 is composed of a sleeve and a moving rod, one end of the moving rod passes through and extends into the interior of the sleeve, a limiting block located inside the sleeve is fixedly connected to the outside of the moving rod, and a through hole adapted to the moving rod is opened on one side of the sleeve.

[0031] Specifically, pulling the baffle 20 causes the fixed rod 15 to move downwards, compressing the telescopic rod 11 and spring 12, causing them to retract. The sliding connection between the support plate 8 and the support groove 9 supports the baffle 20, improving its stability. The positioning block 7 is inserted into the positioning groove 13, making the sponge cover 5 and the cover body 2 fit together. The fixed rod 15 and the fixing hole 14 are on the same center line. Releasing the baffle 20 allows the fixed rod 15 to reset under the action of the spring 12, inserting it into the fixing hole 14. The gap between the fixed rod 15 and the fixing hole 14 fixes the sponge cover 5.

[0032] In this embodiment, the blade body 16 is provided with a support assembly, which includes two support rods 4. The two support rods 4 are fixedly connected to the left and right sides of the blade body 16, respectively. The inner top wall of the sponge cover 5 is provided with two support holes 19. The two support rods 4 extend into the two support holes 19, respectively. The inner bottom wall of the cover 2 is fixedly inlaid with two magnets 18, and the two magnets 18 are attached to the connecting ring 17.

[0033] Among them, the support rod 4 is an L-shaped elastic rod, the support rod 4 and the support hole 19 are fitted with a clearance, and the magnet 18 and the connecting ring 17 are magnetically attracted.

[0034] Specifically, pulling the support rod 4 causes it to deform, pushing the sponge cover 5 into the interior of the cover body 2. The blade body 16 passes through the clearance hole 21, positioning the support rod 4 at the bottom of the support hole 19. Pushing the support rod 4 back to its original position allows it to be inserted into the support hole 19. The gap between the support rod 4 and the support hole 19 restricts the top of the sponge cover 5. The top of the sponge cover 5 is then fixed by the magnetic attraction between the magnet 18 and the connecting ring 17.

[0035] The working principle of the above embodiments is as follows:

[0036] Pulling the support rod 4 causes it to deform, pushing the sponge cover 5 into the interior of the cover body 2. The blade body 16 passes through the clearance hole 21, positioning the support rod 4 at the bottom of the support hole 19. Pushing the support rod 4 back to its original position, the support rod 4 is inserted into the support hole 19. The gap between the support rod 4 and the support hole 19 restricts the top of the sponge cover 5. The top of the sponge cover 5 is fixed by the magnetic attraction between the magnet 18 and the connecting ring 17. Pulling the baffle 20 causes the baffle 20 to move the fixing rod 15 downward, thus affecting the telescopic rod 11 and the spring. 12 is squeezed, causing the telescopic rod 11 and spring 12 to retract. Through the sliding connection between the support plate 8 and the support groove 9, the baffle 20 is supported, improving the stability of the baffle 20. The sponge cover 5 is pushed, so that the sponge cover 5 and the cover body 2 fit together. The positioning block 7 is inserted into the interior of the positioning groove 13. The fixing rod 15 and the fixing hole 14 are located on the same center line. The baffle 20 is released. Under the action of the spring 12, the fixing rod 15 is pushed to reset. The fixing rod 15 is inserted into the interior of the fixing hole 14. Through the gap fit between the fixing rod 15 and the fixing hole 14, the sponge cover 5 is fixed.
