The robotic arm is fixedly connected to the fuselage, and the drill bit is fixedly connected to the robotic arm. The robotic arm can control the rotation and lifting of the drill bit; the placement table is fixedly connected to the fuselage, and the placement table is directly corresponding to the drill bit. The placement table is used to carry the workpiece; the robotic arm can drive the drill bit to drill the workpiece on the placement table.

[0005] The above-mentioned prior art solutions have the following drawbacks: prolonged high-speed rotation and friction will cause the drill bit temperature to rise, and excessively high temperature may cause damage to the drill bit. Utility Model Content

[0006] In order to achieve the effect of cooling the drill bit during the process of drilling a workpiece, the present application provides a drill bit cooling device for a drilling machine.

[0007] The above technical objectives of this application are achieved through the following technical solutions:

[0008] A drill bit cooling device for a drilling machine includes a water tank, a circulation component and a spray head. The water tank is placed on a working surface. One end of the circulation component is connected to the water tank, and the other end is connected to the spray head. The spray head is set to aim at the drill bit. The circulation component draws water from the water tank to the spray head. After the spray head sprays water to cool the drill bit, the circulation component guides the used water back to the water tank.

[0009] By adopting the above solution, the circulation component can draw water from the water tank to spray and cool the drill bit, thereby preventing the drill bit from being damaged by overheating, thereby achieving the effect of cooling the drill bit during the process of drilling a workpiece.

[0010] Furthermore, the circulation component includes a water suction pipe, a branch pipe, a driving member, a baffle plate and a guide plate, one end of the water suction pipe is inserted below the liquid level of the water tank, and the other end is connected to the branch pipe; the spray head is connected to the branch pipe; the baffle plate is arranged on both sides and the rear side of the placement table and is fixedly connected to the placement table; one end of the guide plate is fixedly connected to the front side of the placement table, and the other end of the guide plate is tilted downward and corresponds to the top wall of the water tank; the top wall of the water tank is opened; a support assembly is provided corresponding to the circulation component and the spray head, and the support assembly is used to support the spray head and the circulation component; the driving member is connected to the water suction pipe, and the driving member is used to pump water in the water tank into the water suction pipe.

[0011] By adopting the above scheme, because a driving member is provided, the driving member can pump the water in the water tank into the water extraction pipe, and because the water extraction pipe is connected to the sprinkler head, the water entering the water extraction pipe can be sprayed onto the surface of the drill bit through the sprinkler head, so that the drill bit can be cooled; the water after spraying the drill bit will flow to the placement table under the action of gravity, because a blocking plate is provided, the blocking plate can limit the flow direction of the water flow; and because a guide plate is provided, the water flows out along the guide plate; finally, the water flows through the guide plate into the water tank, thereby completing the operations of pumping, spraying and recycling.

[0012] Furthermore, the branch pipe is U-shaped as a whole, and both ends of the branch pipe are connected to a corresponding spray head. Each spray head is arc-shaped, and the two spray heads are arranged on both sides of the drill bit symmetrically and the spray ports are opposite.

[0013] By adopting the above solution, the spraying range of the spray head is increased and the cooling effect on the drill bit is enhanced.

[0014] Furthermore, the support assembly includes a U-shaped plate and a bearing plate. The U-shaped plate can be raised and lowered to the fuselage, and the U-shaped plate supports the branch pipe. There are two bearing plates, and each bearing plate and the U-shaped plate can be adjusted in angle, and the bearing plate is used to support the sprinkler head.

[0015] By adopting the above scheme, the setting of the support assembly can support the branch pipe and the sprinkler head; then adjusting the relative position relationship between the U-shaped plate and the fuselage can adjust the height of the supporting plate, and thus the position of the sprinkler head relative to the drill bit can be adjusted; and because the supporting plate and the U-shaped plate are adjustable, the angle of the sprinkler head's spray port relative to the drill bit can be adjusted.

[0016] Furthermore, a telescopic assembly is provided between the U-shaped plate and the vehicle body, and the telescopic assembly includes a sleeve, an inner rod and a top screw. The bottom wall of the sleeve is fixedly connected to the fuselage, and the inner rod is inserted into the sleeve, and the inner rod can be raised and lowered along the sleeve; one end of the inner rod facing away from the bottom wall of the sleeve is fixedly connected to the U-shaped plate; the top screw passes through the sleeve and abuts against the inner rod, and the top screw is threadedly connected to the sleeve.

[0017] By adopting the above scheme, the relative position relationship between the inner rod and the sleeve can be adjusted by adjusting the movement of the inner rod along the sleeve, that is, the overall length of the telescopic assembly can be controlled, so that the height of the U-shaped plate relative to the placement table can be controlled, so that the height of the branch pipe and the sprinkler head can be controlled.

[0018] Furthermore, a hinge assembly is provided between the U-shaped plate and the supporting plate, and the hinge assembly includes a connecting block, a hinge ball and a fixing member. One end of the connecting block is fixedly connected to the side wall of the U-shaped plate, and the other end of the connecting block is provided with a hinge groove. The hinge ball is rotatably connected to the hinge groove, and the hinge ball is fixedly connected to the side wall of the supporting plate; the fixing member passes through the side wall of the hinge groove and abuts against the hinge ball, and the fixing member is threadedly connected to the side wall of the hinge groove.

[0019] By adopting the above scheme, the angle of the supporting plate can be controlled by controlling the rotation of the articulated ball in the articulated groove, and the angle of the supporting plate and the articulated ball are adjusted synchronously, so that the angle of the sprinkler head placed on the supporting plate relative to the drill bit can be adjusted. When the relative position relationship between the articulated ball and the articulated groove is determined, the fixing part is rotated until it abuts against the articulated ball, so that the relative position relationship between the articulated ball and the articulated groove is locked.

[0020] Furthermore, a relatively close side of the upper surface of the two supporting plates is provided with a connecting groove, and a corresponding protective plate is plugged into each connecting groove; and each protective plate is provided with a plurality of water holes.

[0021] By adopting the above solution, the protective plate is used to block the debris emitted when the drill bit cuts the workpiece, thereby preventing the debris from clogging the spray port of the spray head.

[0022] Furthermore, a filter plate is provided inside the water tank, and the filter plate is detachably connected to the inner wall of the water tank; the position where the water pump is connected to the water tank is located between the filter plate and the bottom wall of the water tank.

[0023] By adopting the above solution, the filter plate is used to filter the recycled water.

[0024] In summary, this application has the following technical effects:

[0025] 1. By setting up a cooling device, the circulation component can draw water from the water tank to spray and cool the drill bit, preventing the drill bit from being damaged by overheating, and achieving the effect of cooling the drill bit during the process of drilling the workpiece;

[0026] 2. By setting up branch pipes, the spray range of the sprinkler head is expanded, and the cooling effect on the drill bit is enhanced;

[0027] 3. By setting up a hinge assembly, the angle of the carrier plate can be controlled by controlling the rotation of the hinge ball in the hinge groove. The angle of the carrier plate and the hinge ball are adjusted synchronously, so that the angle of the sprinkler head placed on the carrier plate relative to the drill bit can be adjusted.
