A chip discharge pipe 18 connected to the collecting groove 17 is installed on the rear side of the processing seat 1, and the flushing water and the flushed metal debris are discharged from the chip discharge pipe 18. A water supply component 15 is installed on the frame, and a drilling drive component 3 is installed on the moving mechanism 14. A drill rod 2 is installed on the drilling drive component 3. The drilling drive component 3 includes a motor 31 and a tool sleeve 352. The motor 31 is used to drive the drill rod 2 to drill a hole. The motor 31 drives the drilling drive component 3 to rotate, and then the drilling drive component 3 drives the drill rod 2 to rotate and drill a hole. A spray component 4 is arranged outside the tool sleeve 352, and the spray component 4 includes a U-shaped slide seat 41, the U-shaped slide 41 is stuck on the outside of the I-shaped sleeve 352 and slides. The outer wall of the I-shaped sleeve 352 is provided with multiple racks 353 in a ring array. A gear 45 is movably installed on the inner side of the U-shaped slide 41. A stepper motor 46 is installed on the top of the U-shaped slide 41. The stepper motor 46 is used to drive the gear 45 to rotate. The gear 45 is meshed with the rack 353. The gear 45 is limited between the top and bottom horizontal ends of the I-shaped structure of the I-shaped sleeve 352. A water collecting box 43 is installed at the bottom of the U-shaped slide 41. The water collecting box 43 is provided with a water spray head 44 facing the bottom of the drill pipe 2. The water supply component 15 is connected to the water collecting box 43 using a water supply pipe 42. The water supply component 15 includes a water supply tank and a water pump. The water pump connects the water tank and the water supply pipe 42.

[0031] The protective vertical plate 12 is a U-shaped structure, and two protective doors 13 are provided at the opening of the protective vertical plate 12. One end of the protective door 13 slides through the protective vertical plate 12, and the bottom end of the protective vertical plate 12 is a T-shaped structure. The upper end surface of the processing seat 1 is provided with a slide groove that cooperates with the sliding of the protective vertical plate 12, and a chip removal port 11 is provided in the middle of the slide groove. Both ends of the slide groove pass through both sides of the processing seat 1. The setting of the chip removal port 11 is convenient for discharging metal debris in the slide groove. The two protective doors 13 are opened by horizontal sliding, which makes it convenient to place the metal product on the processing table 16. By closing the two protective doors 13, the protective doors 13 and the protective vertical plate 12 are used to prevent the flying of metal debris during grinding.

[0032] The top edge of the I-shaped sleeve 352 is bent upward, and the bottom edge of the I-shaped sleeve 352 is bent downward. Two upper and lower arc grooves 411 are opened on the inner side of the U-shaped slide 41 for sliding cooperation with the bent parts at the top and bottom of the I-shaped sleeve 352; the upward bent part of the I-shaped sleeve 352 is inserted into the top arc groove 411, and the downward bent part of the I-shaped sleeve 352 is inserted into the bottom arc groove 411, which can limit the sliding of the U-shaped slide 41 on the I-shaped sleeve 352.

The spray water of the sprinkler head 44 can not only cool the drill rod 2 and improve the service life of the drill rod 2, but also the sprinkler head 44 can be used for unidirectional flushing without moving, so that the metal debris moves in a unidirectional direction to the collection tank 17. The movement mode of the stepper motor 46 is to drive the gear 45 to rotate, and the gear 45 cooperates with the rack 353 to make the U-shaped slide 41 rotate around the tool sleeve 352, and then the stepper motor 46 drives the U-shaped slide 41 to rotate back and reset, so that the debris around the grinding position of the drill rod 2 can be blown to the collection tank 17 from all directions, so that the debris at the grinding position is collected and processed, and the punching efficiency and punching quality of metal accessories are ensured.

[0034] Example 2

[0035] Reference Figure 1-7 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:

[0036] The drilling drive assembly 3 also includes a quick-release sleeve 34. A motor shaft 32 is provided at the bottom of the motor 31. The motor shaft 32 is installed at the top of the quick-release sleeve 34 using a first bolt and nut set 33. A second bolt and nut set 36 is used to install the top of the drill rod 2 and the quick-release sleeve 34. The drill rod 2 is not directly installed on the motor shaft 32 to avoid direct conduction and heat exchange between the heat generated by the operation of the motor 31 and the drill rod 2.

[0037] Two groups of sickle grooves 341 are provided on the outer wall of the quick-release sleeve 34. The hole of the quick-release sleeve 34 for installing the drill rod 2 is connected to the sickle grooves 341. During the circular rotation of the quick-release sleeve 34, the sickle grooves 341 guide the wind to enter, thereby dissipating the heat from the top outer wall of the drill rod 2, so as to reduce the heat loss of the drill rod 2.

[0038] The outer wall of the quick-release sleeve 34 is provided with a plurality of air exchange blades 342 in a circular array, and the work-shaped sleeve 352 is sleeved on the outside of the plurality of air exchange blades 342. The quick-release sleeve 34 is movably mounted with an adapter sleeve 35 using a bearing sleeve, and the adapter sleeve 35 is connected to the work-shaped sleeve 352 through a plurality of connecting rods 351. During the circular rotation of the quick-release sleeve 34, the air exchange blades 342 blow the wind from above to the bottom of the drill hole of the drill rod 2, which not only blows the metal debris downward to reduce the possibility of the metal debris flying around, but also cools the drill rod 2 by air, further reducing the heat loss of the drill rod 2.

[0039] The motor 31 is installed with the moving slider of the moving mechanism 14, a bracket is installed at the bottom of the motor 31, the connecting rod 351 is connected with the vertical rod 354, the top of the vertical rod 354 is installed with the bracket of the motor 31, and the vertical rod 354 is used to ensure the stability of the industrial sleeve 352, so that the quick-release sleeve 34 rotates and the industrial sleeve 352 does not move.

[0040] When in use, by further optimizing the installation method of the drill rod 2, by setting the sickle groove 341 and the air exchange blade 342, and utilizing the drilling rotation of the drill rod 2, the automatic air cooling and heat dissipation effect of the drill rod 2 is achieved, thereby reducing the heat loss of the drill rod 2 and increasing the service life of the drill rod 2.

[0041] The remaining structures are the same as those of Example 1.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
