[0036] like Figures 1 to 8 As shown, the present application provides a drilling device for metal processing, including a workbench 100, a bracket 110 and a driving assembly 130, wherein the bracket 110 is fixed on the workbench 100, and further includes a protective assembly 200, wherein the protective assembly 200 is used to prevent coolant and waste chips from being discharged outward;

[0037] The protection assembly 200 includes a mounting seat 210 and a positioning ring 220;

[0038] The mounting seat 210 is a cylinder and is fixed on the bracket 110. A cooling pipe 211 is fixed on the mounting seat 210. The cooling pipe 211 is used to transport coolant. A drill bit 212 is fixed at the bottom of the mounting seat 210. The driving assembly 130 is used to drive the drill bit 212 to move and complete the drilling action. A threaded groove is opened on the outer side of the mounting seat 210.

[0039] The positioning ring 220 is a circular ring, and a thread strip is fixed on the inner side of the positioning ring 220. The thread strip on the inner side of the positioning ring 220 cooperates with the thread groove on the outer side of the mounting seat 210. The positioning ring 220 and the mounting seat 210 are detachably connected.

[0040] The bottom of the positioning ring 220 is provided with a plurality of arc-shaped baffle plates 221 distributed in an annular manner, and the plurality of baffle plates 221 form an inverted frustum-shaped cover body, and the bottom of the baffle plates 221 can contact the surface of the metal plate, and the baffle plates 221 can deform with the depth of the drill bit 212 drilling into the metal plate, without affecting the work of the drill bit 212;

[0041] There are gaps between the baffle plates 221, the gaps are in the range of 0.2 cm to 0.3 cm, and the water outlet of the cooling tube 211 extends from the gaps of the baffle plates 221. That is, the baffle plates 221 are split-type designs without affecting the blocking of the coolant and waste chips.

[0042] In the above embodiment, when the drill bit 212 is working, the cooling tube 211 sprays coolant to cool the drill bit 212 to avoid annealing of the drill bit 212. The material baffle plate 221 is covered on the outside of the drill bit 212 to reduce the splashing of the coolant. As the driving assembly 130 drives the drill bit 212 to move, the material baffle plate 221 maintains contact with the surface of the metal plate, and can scrape off the coolant and waste chips on the surface of the metal plate to avoid the accumulation of coolant and waste chips on the surface of the metal plate, thereby ensuring the drilling quality of the metal plate and improving the processing efficiency.

[0043] In some embodiments of the present application, Figures 4 to 8 As shown, a ring plate 224 is fixed to the bottom of the baffle plate 221, and a plurality of baffle plates 221 are fixed together. A plurality of flexible scrapers 225 are detachably connected to the bottom of the ring plate 224. The flexible scrapers 225 are in contact with the surface of the metal plate, and there are gaps between adjacent flexible scrapers 225.

[0044] It is easy to understand that the flexible scraper 225 can scrape the liquid on the surface of the metal plate, and the scraping effect is better. The flexible scraper 225 can be disassembled. When a flexible scraper 225 is damaged, the damaged flexible scraper 225 can be directly replaced without replacing the entire structure.

[0045] Specifically, if Figure 7 As shown, a metal moving plate 223 is fixed on the outer ring surface of the positioning ring 220, and a magnetic cleaning plate 226 is fixed on the inner ring surface of the positioning ring 220. The magnetic cleaning plate 226 can be magnetically attracted to the metal moving plate 223;

[0046] It is easy to understand that the mobile metal moving plate 223 can drive the magnetic cleaning plate 226 to move on the inner side of the baffle plate 221, scrape off the waste liquid on the inner ring surface of the baffle plate 221, and at the same time scrape off the impurities adsorbed on the inner side of the baffle plate 221, so as to facilitate the cleaning of the baffle plate 221;

[0047] like Figure 7 As shown, the outer ring surface of the magnetic cleaning plate 226 is fixed with protrusions, and the protrusions on the magnetic cleaning plate 226 can contact the inner side surface of the baffle plate 221. The protrusions can increase the contact force with the inner side surface of the baffle plate 221 to better clean the baffle plate 221.

[0048] In the above embodiment, the flexible scraper 225 is provided to facilitate scraping of liquid and waste on the surface of the metal plate, and to facilitate removal and replacement of the flexible scraper 225, and the movable metal moving plate 223 can drive the magnetic cleaning plate 226 to move on the inner side of the baffle plate 221, and the convex points on the magnetic cleaning plate 226 are used to increase the contact force with the inner side of the baffle plate 221, so that impurities on the baffle plate 221 can be better cleaned without frequent disassembly and cleaning.

[0049] In some embodiments of the present application, Figures 1 to 3 As shown, it also includes a positioning assembly 120, which is used to fix the metal plate;

[0050] The positioning assembly 120 includes a fixing plate 121 and a screw rod 122;

[0051] The fixing plate 121 has an opening and is fixed on the workbench 100. The screw 122 extends into the opening of the fixing plate 121. The opening of the fixing plate 121 has an internal thread that cooperates with the external thread of the screw 122. The screw 122 and the fixing plate 121 form a threaded connection.

[0052] A rotating handle 123 is fixed to one end of the screw rod 122, and a positioning block 124 is fixed to one end of the screw rod 122;

[0053] Specifically, if Figures 1 to 3 As shown, there are four positioning components 120 , and the four positioning components 120 are distributed on the side of the metal plate.

[0054] In the above embodiment, the metal plate is placed between the positioning components 120, and the screw 122 can be driven to rotate by turning the rotating handle 123, so that the screw 122 makes the positioning block 124 rest against the side of the metal plate. The screw 122 achieves a self-locking effect while transmitting power through the action of the thread, thereby effectively preventing the screw 122 from loosening. Repeat the above operation and fix the metal plate through the four positioning components 120.

[0055] In some embodiments of the present application, Figures 1 to 3 As shown, the driving assembly 130 includes a guide rod 131, a reciprocating screw rod 132 and a driving source 133;

[0056] The guide rod 131 is fixed on the bracket 110, the reciprocating screw rod 132 is fixed on the bracket 110, the guide rod 131 is parallel to the reciprocating screw rod 132, and the mounting seat 210 is positioned on the reciprocating screw rod 132 and the guide rod 131;

[0057] The driving source 133 is used to drive the reciprocating screw rod 132 to rotate. The driving source 133 is a motor, and the driving source 133 is fixed on the bracket 110 .

[0058] In the above embodiment, by starting the driving source 133, the reciprocating screw 132 can be driven to rotate, and the mounting seat 210 can be driven to move. The guide rod 131 limits and guides the mounting seat 210, which can prevent the mounting seat 210 from flipping over and make the drill bit 212 move synchronously, thereby ensuring the stability of use and facilitating the drilling of metal plates.

[0059] In some embodiments of the present application, Figures 1 to 3As shown, a collecting groove 150 is opened on the workbench 100, and the collecting groove 150 is located below the drill bit 212. A reserved groove is opened in the workbench 100, and the reserved groove is communicated with the inside of the collecting groove 150. A collecting box 140 is positioned in the reserved groove, and a filter screen 141 is detachably connected to the collecting box 140.

[0060] In the above embodiment, the waste chips generated by drilling are conveniently collected by setting the collection groove 150, and the scraped coolant can enter the collection groove 150 and fall into the collection box 140. The solid and liquid are separated by the filter 141, and the coolant is collected at the bottom of the collection box 140, and the waste chips remain on the filter 141. The filter 141 can be taken out to collect and process the waste chips, which reduces the accumulation of waste chips and coolant while collecting both, thereby increasing the functionality of use.

[0061] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
