By setting up a powder collection component, the position of the limit bolt in the first through hole can be adjusted according to the needs of use, and the protruding length of the connecting rod can be adjusted, so as to flexibly adjust the position of the collecting groove. At the same time, the chip groove on the surface of the thread milling cutter body is relatively fitted with the bottom collecting port of the collecting groove. When the workpiece is processed, the high-speed rotation of the thread milling cutter body will quickly cut the workpiece, and the generated debris will enter the interior of the collecting groove through the chip groove. At the same time, the magnet inside the collecting groove will collect and adsorb the metal powder for easy recycling. The set brush can block the collection port to prevent the collected powder from falling. This setting improves the problem that the existing milling cutter cannot prevent chips or powder from falling when processing the workpiece. The falling chips or powder can easily cause the milling cutter and the workpiece and waste chips to expand, causing damage to the workpiece or reducing the service life of the thread milling cutter.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1

[0024] like Figures 1 to 4As shown, a deburring thread milling cutter with a powder collection structure comprises a thread milling cutter body 1, a milling cutter internal cooling component 4 located inside the thread milling cutter body 1, and a powder collection component 5 located outside the thread milling cutter body 1;

[0025] The powder collection assembly 5 includes a connecting rod sleeve 501, and a connecting rod 502 is sleeved inside the connecting rod sleeve 501. First through holes 504 are provided on both sides of the bottom of the connecting rod sleeve 501, and multiple groups of second through holes 505 are provided on the left and right sides of the connecting rod 502. Limit bolts 503 are inserted into the first through holes 504 and the second through holes 505. A collecting groove 506 is fixedly connected to the bottom of the connecting rod 502, and brushes 507 are fixedly installed around the bottom collecting port of the collecting groove 506. When processing a workpiece, the high-speed rotation of the thread milling cutter body 1 will quickly cut the workpiece, and the generated debris will enter the interior of the collecting groove 506 through the chip removal groove 2. This arrangement improves the problem that the existing milling cutter cannot prevent debris or powder from falling when processing the workpiece. The falling debris or powder can easily cause the milling cutter and the workpiece and waste chips to expand, causing damage to the workpiece or reducing the service life of the thread milling cutter. Embodiment 2

[0026] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0027] The bottom of the thread milling cutter body 1 is provided with a plurality of chip removal grooves 2, which can be used for chip removal.

[0028] A file shaft 3 is fixedly arranged in the middle of the thread milling cutter body 1, wherein the cross section of the file shaft 3 is circular, and the patterns on the file shaft 3 are interlaced, and the diameter of the file shaft 3 is slightly larger than the thread milling cutter body 1. After the thread depth is processed to the right level, the file shaft 3 can remove the burrs at the tail of the product thread to prevent the residual burrs at the tail of the product thread, effectively improve the processing quality of the product, and at the same time do not affect the product appearance and thread use.

[0029] The milling cutter internal cooling assembly 4 comprises a liquid storage tank 402 , and a liquid inlet 401 is provided on one side of the liquid storage tank 402 . When in use, the coolant can be introduced into the liquid storage tank 402 through the liquid inlet 401 . Embodiment 3

[0030] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0031] The bottom of the liquid storage tank 402 is connected to four groups of coolant direct discharge channels 403. The design structure of the coolant direct discharge channels 403 extending completely in a straight line is conducive to the rational manufacture of the thread milling cutter body 1 on the one hand, and the continuous straight coolant direct discharge channels 403 also have the advantage of small flow resistance on the other hand.

[0032] At the ends of multiple groups of coolant direct discharge channels 403, coolant outflow holes 404 are provided, and the coolant is discharged through the coolant outflow holes 404. This setting improves the problem that a large amount of heat is generated when the cutter head of the thread milling cutter body 1 processes the workpiece, and excessive heat accumulation will cause the cutter head to be easily worn during use, affecting its service life.

[0033] The thread milling cutter body 1 penetrates through the inside of the collection groove 506. A magnet is fixedly installed on the bottom inner wall of the collection groove 506, and the magnet inside the collection groove 506 collects and adsorbs metal powder for recycling.

[0034] Working principle: When using the deburring thread milling cutter with a powder collection structure, through the provided grinding shaft 3, the cross-section of the grinding shaft 3 is circular, and the patterns on the grinding shaft 3 are cross-shaped. At the same time, the diameter of the grinding shaft 3 is slightly larger than that of the thread milling cutter body 1. After the thread depth processing is in place, the grinding shaft 3 can remove the burrs at the tail of the product thread, preventing burrs from remaining at the tail of the product thread, effectively improving the processing quality of the product, and at the same time not affecting the appearance and thread use of the product; through the provided milling cutter internal cooling component 4, when in use, the coolant is introduced into the liquid storage tank 402 through the liquid inlet 401, and then the coolant is discharged through the coolant outflow holes 404 through the coolant direct discharge channels 403. This setting improves the problem that a large amount of heat is generated when the cutter head of the thread milling cutter body 1 processes the workpiece, and excessive heat accumulation will cause the cutter head to be easily worn during use, affecting its service life. The design structure in which the coolant direct discharge channels 403 extend completely linearly is beneficial to the reasonable manufacture of the thread milling cutter body 1 on the one hand, and on the other hand, the continuous straight coolant direct discharge channels 403 also have the advantage of small flow resistance; through the provided powder collection component 5, the position of the limit bolt 503 in the first through hole 504 can be adjusted according to the use needs, so as to adjust the protruding length of the connecting rod 502, thereby flexibly adjusting the position of the collection groove 506. At the same time, the chip discharge groove 2 on the surface of the thread milling cutter body 1 is relatively fitted with the bottom collection port of the collection groove 506. When processing the workpiece, due to the high-speed rotation of the thread milling cutter body 1, the workpiece will be quickly cut, and the generated chips will enter the inside of the collection groove 506 through the chip discharge groove 2. At the same time, the magnet inside the collection groove 506 collects and adsorbs metal powder for recycling. The provided brush 507 can block the collection port to prevent the collected powder from falling. This setting improves the problem that when the existing milling cutter processes the workpiece, it is impossible to prevent chips or powder from falling, and the falling chips or powder easily cause the milling cutter and the workpiece to expand with the waste chips, resulting in workpiece damage or a decrease in the service life of the thread milling cutter.
