Description

Technical Field

[0001] The utility model belongs to the field of milling cutters, and in particular relates to a modular reconfigurable high-efficiency milling cutter. Background Art

[0002] A milling cutter is a rotating tool used for milling processing. It generally has one or more teeth. When working, each tooth cuts off the excess of the workpiece intermittently in turn. The milling cutter is mainly used to process planes, steps, grooves, formed surfaces and cut off workpieces on milling machines.

[0003] When processing metal objects, the wear of the milling cutter will increase, and the milling cutter needs to be replaced. Common milling cutters only have one or two processing ends, and when the processing ends are excessively worn, they need to be replaced. In view of this, the present invention is proposed.

Detailed implementation manners

[0030] Now, the present utility model will be further described in detail with reference to the attached drawings.

[0031] Please refer to Figures 1 to 9 , the present utility model provides a technical solution: a modular and recombinable high - efficiency milling cutter, including a bottom cover 1, an upper cover 2 and a milling cutter head 8. The front end of the bottom cover 1 is provided with the upper cover 2. Reserved holes 5 for the connecting shaft 3 and the stud 4 to pass through are provided in the middle of both the bottom cover 1 and the upper cover 2. A fixed groove 6 for placing the bottom cover 1 is opened at the lower end of the connecting shaft 3. A nut 7 is installed outside the stud 4. Fixing cavities for installing the milling cutter head 8 are opened at the four corners of the bottom cover 1. Relief grooves 9 matching the side parts of the milling cutter head 8 are opened at the side ends of both the fixing cavities and the upper cover 2. A special - shaped limit post 11 that fits the internal contour of the limit hole 10 in the middle of the milling cutter head 8 is fixed in the middle of each fixing cavity;

[0032] The outer shape of the milling cutter head 8 is an equilateral triangle structure design, and the three ends of the milling cutter head 8 are processing ends;

[0033] A receiving groove 12 for placing the milling cutter head 8 is also provided in the middle of the fixing groove 6. Considering that the wear of the milling cutter will increase when processing metal objects, the milling cutter needs to be replaced. Common milling cutters have only one or two processing ends. When the processing ends are excessively worn, they need to be replaced. The utility model uses a triangular milling cutter head 8 so that each end can be a processing end. Therefore, compared with the existing single-head or double-head milling cutter head 8, this device has 12 processing ends that can be used for milling processing, which is more practical. The user does not need to frequently replace the entire milling cutter. The user only needs to take out the milling cutter head 8 and rotate it to the next unused processing and then install it with the special-shaped limit column 11.

[0034] Among them, the outside of the special-shaped limiting column 11 is evenly spaced with protruding ends that are adapted to the concave surface inside the limiting hole 10, and each concave surface position of the limiting hole 10 is aligned with the processing end position of the milling cutter head 8. Considering that the external shape of the milling cutter head 8 is an equilateral triangle, the center of each cutter head needs to be aligned with the protruding end of the special-shaped limiting column 11 and the concave surface of the limiting hole 10. Therefore, the processing end of the milling cutter head 8 is aligned with each concave surface position of the limiting hole 10, thereby ensuring that each time the processing end is replaced, the installation position of the next processing end to be replaced will not be offset, resulting in skewed installation.

[0035] Among them, a polyurethane block 13 is fixed inside each fixed cavity, which is in contact with the side of the milling cutter head 8. By setting the polyurethane block 13, the side end of the fixed cavity and the milling cutter head 8 is in contact, thereby avoiding the existence of a gap between the milling cutter head 8 and the fixed cavity to affect the stability of the milling cutter head 8 during use.

[0036] Among them, a positioning ring 14 is fixed to the middle of the bottom cover 1, and the outer size of the positioning ring 14 is smaller than the inner size of the annular positioning kit 15. The annular positioning kit 15 is fixedly installed on the back of the upper cover 2, and the position of the annular positioning kit 15 is set one-to-one with the position of the positioning ring 14. An annular magnetic block 17 for magnetically adsorbing a metal ring 16 is fixed inside the annular positioning kit 15, and the metal ring 16 is fixedly installed on the front end surface of the positioning ring 14. By arranging the positioning ring 14, the metal ring 16, the annular positioning kit 15 and the annular magnetic block 17, it is convenient for users to install the upper cover 2 and the bottom cover 1, that is, after the upper cover 2 and the bottom cover 1 are closed, the annular magnetic block 17 and the metal ring 16 will be magnetically adsorbed to complete the alignment.

[0037] Among them, a plurality of positioning bars 18 are arranged in a cross-shaped array in the middle of the bottom cover 1, and the external dimensions of the positioning bars 18 match the internal dimensions of the strip-shaped positioning kit 19. The number of the strip-shaped positioning kits 19 corresponds one-to-one to the number of the positioning bars 18. By setting the positioning bars 18 and the strip-shaped positioning kits 19, it is convenient for the user to complete the alignment installation when installing the bottom cover 1 and the upper cover 2, so that each milling cutter head 8 is just positioned by the fixing cavity and the relief groove 9 of the upper cover 2.

[0038] Among them, a plurality of groups of symmetric anti-detachment toughness bars 20 are arranged in the interior of the bottom cover 1, and the bottom cover 1 is fixed to the upper cover 2 by buckling the anti-detachment groove 21 through the anti-detachment toughness bars 20. The anti-detachment groove 21 is opened in the middle of the upper cover 2. By setting the anti-detachment toughness bars 20 to cooperate with the anti-detachment groove 21, the upper cover 2 and the bottom cover 1 are fixed. That is, during installation, the positioning bars 18 and the strip-shaped positioning kits 19 are first used for docking and positioning, and then the anti-detachment toughness bars 20 are inserted into the back of the anti-detachment groove 21. Subsequently, the front end of the anti-detachment toughness bar 20 is reset to abut against the side wall edge of the anti-detachment groove 21 to complete the fixing process of the upper cover 2 and the bottom cover 1. During disassembly, the symmetric anti-detachment toughness bars 20 are pressed in sequence so that the front edge thereof no longer abuts against the edge of the anti-detachment groove 21, and then the upper cover 2 can be removed.

[0039] The present utility model is not limited to the above embodiments. Any person should know that structural changes made under the inspiration of the present utility model, as long as they have the same or similar technical solutions as the present utility model, all fall within the protection scope of the present utility model.
