[0050] The telescopic motor 19 is fixedly arranged on the top of the support frame 3, and the telescopic motor 19 is connected to the telescopic rod 22;

[0051] The movable plate 20 is fixedly arranged at the bottom of the telescopic rod 22;

[0052] The drill bits 21 are evenly and equidistantly fixed on the bottom of the movable plate 20;

[0053] The fixed cooling unit is arranged on the workbench 1, and includes a driving component, a fixing component 42, a cooling component 43 and a cleaning component 44; the driving component drives the fixing component 42 to move; the driving component drives the cooling component 43 to move up and down; the driving component drives the cleaning component 44 to move;

[0054] The automobile flange to be processed is placed on the fixing component 42, and the driving component drives the fixing component 42 to move and fix the automobile flange. While fixing the automobile flange, the driving component also drives the cooling component 43 to move up and down, so that the cooling component 43 moves to a specified position, and then the automobile flange is drilled by the drilling. While drilling, the cooling component 43 cools the drill bit 21 and the automobile flange, and the sprayed water flows into the cleaning component 44, which is filtered and reused by the cleaning component 44;

[0055] The automobile flange is placed on the fixing assembly 42 of the workbench 1, and then the fixing assembly 42 is driven by the driving assembly to move, and the automobile flange placed on the workbench 1 is fixed, and then the telescopic motor 19 on the support frame 3 drives the telescopic rod 22 to extend and retract, driving the moving disk 20 and the drill bit 21 to move downward, so that the drill bit 21 drills and cuts the automobile flange. The fixing assembly 42 is provided to firmly fix the automobile flange to avoid vibration when the drill bit 21 drills and cuts the automobile flange, causing the automobile flange to deviate, so that the drill bit 21 deviates from the preset drilling and cutting position, causing damage to the automobile flange and causing economic losses;

[0056] When the drill bit 21 is drilling and cutting the automobile flange, the friction between the drill bit 21 and the automobile flange will cause the temperature of the automobile flange and the drill bit 21 to rise sharply. Therefore, when the driving component drives the fixing component 42 to fix the automobile flange, the driving component will also drive the cooling component 43 to rise. When the drill bit 21 is drilling and cutting the automobile flange, the cooling component 43 will spray coolant on the drill bit 21 and the automobile flange to cool the drill bit 21 and the automobile flange, so as to prevent the drill bit 21 and the automobile flange from cracking due to excessive temperature during drilling and cutting.

[0057] The sprayed coolant will cool the drill bit 21 and the automobile flange, and then flow into the bottom of the workbench 1. A cleaning component 44 is provided under the workbench 1. The coolant sprayed on the drill bit 21 and the automobile flange will be mixed with debris from drilling, so the coolant is filtered by the cleaning component 44 and then sent back to the cooling component 43 for repeated use to avoid waste of coolant.

The rising or falling rotating rod 25 drives the telescopic water block 7 and the water spray head 8 to rise or fall on the operating table 9. The purpose of lifting the telescopic water block 7 and the water spray head 8 is that when the automobile flange is placed on the workbench 1 for fixing, if the telescopic water block 7 and the water spray head 8 are fixed and cannot be moved, the telescopic water block 7 and the water spray head 8 may be accidentally bumped during placement, which may easily cause damage to personnel, the telescopic water block 7 and the water spray head 8. At the same time, the lifting telescopic water block 7 and the water spray head 8 can be lifted above the automobile flange and the drill bit 21, so that the cooling liquid can be sprayed on them better.

The moving toothed plate 16 penetrates the processing box 17. When the moving toothed plate 16 moves, the cleaning plate 40 at the bottom of the mounting block 41 cleans the filter plate 34 in the processing box 17. This is set up to prevent the debris in the coolant from clogging the filter plate 34 when the filter plate 34 filters the debris in the coolant. Therefore, the moving cleaning plate 40 reciprocates to clean the filter plate 34 to avoid filtering. The plate 34 is blocked, and holes are provided on the operating table 9 and the workbench 1. The contaminated coolant flows into the processing box 17 through the holes on the operating table 9 and the workbench 1.

[0077] The coolant in the water supply tank 18 is transported to the telescopic water block 7 through the first connecting water pipe 23, and then the coolant is evenly distributed to each telescopic water block 7 through the second connecting water pipe 28, so that the telescopic water block 7 can spray out the coolant smoothly.

[0078] See also Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, a water stop plate 29 is fixedly connected to the workbench 1;

[0079] The purpose of setting a water stop plate 29 on the workbench 1 is to prevent the coolant from flowing out after passing through the operating table 9. Therefore, the coolant is intercepted by the water stop plate 29 and then flows into the processing box 17 through the holes on the workbench 1. There is a certain drop when the coolant drips from the operating table 9 to the workbench 1. This setting is to allow the coolant to cool down quickly during the falling process.

[0080] The working principle of the present invention is as follows: the automobile flange is placed on the fixing assembly 42 of the workbench 1, and then the fixing assembly 42 is driven by the driving assembly to move, the automobile flange placed on the workbench 1 is fixed, and then the telescopic motor 19 on the support frame 3 drives the telescopic rod 22 to telescope, driving the moving disk 20 and the drill bit 21 to move downward, so that the drill bit 21 drills and cuts the automobile flange. The fixing assembly 42 is provided to firmly fix the automobile flange, so as to avoid the vibration generated when the drill bit 21 drills and cuts the automobile flange, causing the automobile flange to deviate, so that the drill bit 21 deviates from the preset drilling and cutting position, causing the automobile flange to be damaged and causing economic losses;

[0081] When the drill bit 21 is drilling and cutting the automobile flange, the friction between the drill bit 21 and the automobile flange will cause the temperature of the automobile flange and the drill bit 21 to rise sharply. Therefore, when the driving component drives the fixing component 42 to fix the automobile flange, the driving component will also drive the cooling component 43 to rise. When the drill bit 21 is drilling and cutting the automobile flange, the cooling component 43 will spray coolant on the drill bit 21 and the automobile flange to cool the drill bit 21 and the automobile flange, so as to prevent the drill bit 21 and the automobile flange from cracking due to excessive temperature during drilling and cutting.

[0082] The sprayed coolant will cool the drill bit 21 and the automobile flange, and then flow into the bottom of the workbench 1. A cleaning component 44 is provided under the workbench 1. The coolant sprayed on the drill bit 21 and the automobile flange will be mixed with debris from drilling, so the coolant is filtered by the cleaning component 44 and then sent back to the cooling component 43 for repeated use to avoid waste of coolant.

[0083] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
