Description

Technical Field

[0001] The utility model relates to the technical field of milling cutters, in particular to a milling cutter facilitating blade replacement. Background Technique

[0002] A milling cutter is a rotating cutter with one or more cutting teeth for milling. During operation, each cutting tooth intermittently cuts off the surplus of the workpiece in turn. Milling cutters are mainly used for machining planes, steps, grooves, formed surfaces and cutting workpieces on milling machines. A PCD double-sided milling cutter has multiple unequal cutting edges and two groups of cutter disks combined, which is a rotating cutter used to cut the machining surface of the steering knuckle of new energy vehicles. Two planes can be machined simultaneously to obtain high-precision dimensions and shapes.

[0003] During the use of the existing milling cutter, the blade and the rotating shaft are usually driven by a flat key. When disassembling and replacing the milling cutter blade, the whole needs to be disassembled and replaced, and the replacement process is rather troublesome. Therefore, we propose a milling cutter facilitating blade replacement. Content of the Utility Model

[0004] In view of the above problems, the utility model provides a milling cutter facilitating blade replacement, which can solve the problems existing in the above background technique.

[0009] In a further technical solution, a fastening bolt is movably connected between the first connection plate and the connection insertion block. A fastening nut is threadedly connected to the outer surface of the end of the fastening bolt. Fixed clamping grooves are formed at the positions where the first connection plate and the second connection plate are close to each other.

[0010] In a further technical solution, the inner side of the fixed clamping groove fits with the inner side of the fixed installation groove.

[0011] In a further technical solution, fixing grooves are symmetrically formed on the outer side of the surface of the first connecting plate, and one end of the fastening bolt away from the fastening nut and the fastening nut are both located inside the fixing grooves.

[0012] In a further technical solution, fixing insertion rods are arranged inside the fixing clamping grooves at the edges of the first connecting plate and the second connecting plate, and fixing insertion holes adapted to the fixing insertion rods are formed on the outer side of the surface of the rotating shaft and inside the fixed installation groove.

[0026] During use, the first connection mechanism 3 and the second connection mechanism 4 are mutually attached, and the first connection mechanism 3 and the second connection mechanism 4 are snapped into the inside of the fixed installation groove 2, so as to be quickly connected, and are mutually attached to the fixed installation groove 2, which can ensure the stability of transmission and is convenient to operate.

[0027] In another embodiment, as Figure 3 shown, the first connection mechanism 3 includes a first connecting plate 6. Fixed slots 7 are symmetrically formed at the bottom of the first connecting plate 6.

[0028] It is convenient for the first connecting plate 6 to be quickly connected to the second connection mechanism 4 through the fixed slots 7.

[0029] In another embodiment, as Figure 4 shown, the second connection mechanism 4 includes a second connecting plate 8. Connecting plugs 9 are symmetrically arranged at the top of the second connecting plate 8.

[0030] It is convenient for the connecting plugs 9 to be inserted into the inside of the fixed slots 7, so that a preliminary connection is made between the first connecting plate 6 and the second connecting plate 8.

[0031] In another embodiment, as Figure 4 shown, a fastening bolt 10 is movably connected between the first connecting plate 6 and the connecting plug 9. A fastening nut 11 is threadedly connected to the outer surface of the end of the fastening bolt 10. Fixed clamping grooves 12 are formed at the positions where the first connecting plate 6 and the second connecting plate 8 are close to each other.

[0032] When the connecting insert block 9 is inside the fixed slot 7, the fastening bolt 10 can be inserted into the first connecting plate 6 and the connecting insert block 9, and the fastening nut 11 is connected and fixed to the end of the fastening bolt 10, so that the whole can be quickly connected and fixed. On the contrary, it can also be quickly disassembled and replaced, which is convenient to operate.

[0033] In another embodiment, as Figure 4 shown, the inner side of the fixed engaging groove 12 fits with the inner side of the fixed mounting groove 2.

[0034] It is convenient for the first connecting plate 6 and the second connecting plate 8 to be clamped inside the fixed mounting groove 2 through the fixed engaging groove 12 and connected to the rotating shaft 1.
