Description

Technical Field

[0001] The utility model relates to the technical field of four-edge cutting milling cutters, in particular to a four-edge cutting milling cutter with a dust collecting cover. Background Art

[0002] A four-edge cutting milling cutter is a multi-edge metal cutting tool characterized by four cutting edges. This milling cutter is mainly used for milling operations and can perform a variety of different metal processing tasks.

[0003] Among them, when a four-edge cutting milling cutter is milling metal, the generated debris will fly everywhere. These flying debris are difficult to clean, so a four-edge cutting milling cutter with a dust cover can prevent the debris from flying.

[0004] The above-mentioned equipment often has the following defects: First, the four-edge cutting milling cutter uses a dust cover to prevent debris from flying. During use, the dust cover must be close to the cut metal. If it is not close, the debris will still fly everywhere. The dust cover must rotate synchronously with the four-edge cutting milling cutter, which will cause wear between one end of the dust cover and the cut metal. Second, the dust cover wraps around the four-edge cutting milling cutter, and the heat generated during the four-edge cutting process is reduced. The accumulated heat reduces the service life of the dust cover and the four-edge cutting milling cutter. Therefore, a heat dissipation integrated mechanism is used to solve the above problems.

[0024] Through the above technical solution, the spring enables the blocking block and the resisting rod to return to their original positions.

[0025] Furthermore, a limiting groove is provided on the outer surface of the four-edge cutting milling cutter body, a limiting block is welded on the inner surface of the sleeve, and a clamping groove is provided on the inner side of the sleeve.

[0037] The following describes exemplary embodiments of the present invention in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0038] like Figure 1 As shown, an embodiment of the present utility model provides a four-edge cutting milling cutter with a dust collecting cover, comprising:

[0039] Four-edge cutting milling cutter body 1;

[0040] A sleeve 2 is engaged with and sleeved on the outer surface of the four-edge cutting milling cutter body 1;

[0041] The heat dissipation integrated mechanism 3 is arranged at one end of the sleeve 2 to prevent cutting residues from splashing around and has a heat dissipation effect on the four-edge cutting milling cutter body 1;

[0042] The clamping mechanism 4 is arranged inside the four-edge cutting milling cutter body 1 and is used for quickly installing and disassembling the sleeve 2.

[0043] When the four-blade cutting milling cutter body 1 cuts the device again, the locking mechanism 4 can quickly install and disassemble the sleeve 2, and then the heat dissipation integrated mechanism 3 on the sleeve 2 prevents debris from splashing, and the heat dissipation integrated mechanism 3 can dissipate heat for the four-blade cutting milling cutter body 1.

[0044] like Figure 3 As shown, the heat dissipation integrated mechanism 3 includes rubber blades 301, which are threadedly connected to the outer surface of the four-blade cutting milling cutter body 1 via bolts 302. The outer surface of the four-blade cutting milling cutter body 1 is provided with a plurality of first heat dissipation holes 303. The first heat dissipation holes 303 increase the heat dissipation area of ​​the four-blade cutting milling cutter body 1. When the four-blade cutting milling cutter body 1 rotates, it drives the rubber blades 301 to rotate as well, thus dissipating heat from the four-blade cutting milling cutter body 1.

[0045] like Figure 2 As shown, a bearing 304 is embedded in the inner wall of the sleeve 2, and a telescopic tube 305 is embedded in the inner surface of the bearing 304. One end of the telescopic tube 305 is fixedly connected to a dust cover 306. The sleeve 2 and the four-flute cutting milling cutter body 1 move synchronously. The bearing 304 prevents the telescopic tube 305 and the dust cover 306 from rotating synchronously with the sleeve 2. The telescopic tube 305 can adjust the height of the dust cover 306.

[0046] like Figure 2 As shown, the outer surface of the dust collecting cover 306 is provided with a second heat dissipation hole 307, and a plurality of second heat dissipation holes 307 are provided on the surface of the dust collecting cover 306. The second heat dissipation holes 307 can discharge the hot air generated inside the dust collecting cover 306.

[0047] In the embodiment of the present invention, when cutting the device again, the dust cover 306 is tightly attached to the device through the telescopic tube 305. When the four-blade cutting milling cutter body 1 drives the sleeve 2 to rotate, the telescopic tube 305 and the dust cover 306 will not rotate synchronously due to the bearing 304, which can prevent the dust cover 306 from contacting the device and causing wear of the dust cover 306. When the four-blade cutting milling cutter body 1 rotates, it will drive the rubber fan blades 301 to rotate, which can discharge the heat accumulated in the dust cover 306, thereby increasing the service life of the four-blade cutting milling cutter body 1.

[0048] like Figure 4 As shown, the engaging mechanism 4 includes a clamping block 401, which is installed through the inner wall of the four-blade cutting milling cutter body 1. The clamping block 401 can move on the inner wall of the four-blade cutting milling cutter body 1. The interior of the four-blade cutting milling cutter body 1 is respectively provided with a first mounting cavity 402, a second mounting cavity 403, and a third mounting cavity 404. The clamping block 401 is large at one end and small at the other end. The clamping block 401 can move on the inner wall of the four-blade cutting milling cutter body 1 but will not detach. The first mounting cavity 402 is larger than the second mounting cavity 403, and the second mounting cavity 403 is larger than the first mounting cavity 402.

[0049] like Figure 4 As shown, a blocking block 405 is provided inside the first installation cavity 402, a spring 406 is provided inside the second installation cavity 403, and a stopper 407 is provided inside the third installation cavity 404. The blocking block 405 can slide in the first installation cavity 402 and the third installation cavity 404.

[0050] like Figure 4 As shown, the blocking block 405, the spring 406 and the push rod 407 are movable in the first mounting cavity 402, the second mounting cavity 403 and the third mounting cavity 404 respectively, and the blocking block 405 slides with the second mounting cavity 403. One end of the blocking block 405 is connected to one end of the push rod 407, and the other end is connected to the spring 406.

[0051] like Figure 5 As shown, the outer surface of the four-edge cutting milling cutter body 1 is provided with a limit groove 408, the inner surface of the sleeve 2 is welded with a limit block 409, and the inner side of the sleeve 2 is provided with a clamping groove 410. The limit groove 408 cooperates with the limit block 409 to enable the four-edge cutting milling cutter body 1 and the sleeve 2 to rotate synchronously.

[0052] In an embodiment of the present utility model, when the sleeve 2 is installed on the four-blade cutting milling cutter body 1, first align the limit block 409 on the sleeve 2 with the limit groove 408 on the four-blade cutting milling cutter body 1, and then use an external tool to press the push rod 407 inward from one end of the four-blade cutting cutter body 1. At this time, the spring 406 will be compressed, the blocking block 405 will move into the second mounting cavity 403, and then the block 401 will move slightly inward. When the slot 410 on the sleeve 2 is aligned with the position of the block 401, stop pressing. At this time, the spring 406 and the blocking block 405 return to their positions and press against the block 40 again, and the block 40 is inserted into the slot 410.

[0053] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
