[0051] A method for using a hydrogen energy power device combined processing machine tool, comprising the following steps:

[0052] First, the butt joint 201 is installed on the drill body 1, and then the drill bit body 204 is installed in the butt joint 201, the drill body 1 is controlled to operate, the drill body 1 drives the drill bit body 204 to rotate at high speed through the butt joint 201, and at the same time drives the drill bit body 204 to move close to the hydrogen energy power device accessory fixed on the machining table 3, the tapered cutter head 401 contacts the hydrogen energy power device accessory, and at this time the drill bit body 204 is still located above the hydrogen energy power device accessory;

[0053] The drill body 1 continues to drive the drill bit body 204 to move downward, pressure is generated between the tapered cutter head 401 and the hydrogen energy power device accessory and gradually increases, the tapered cutter head 401 retracts into the cooling liquid outlet hole A205 under the action of the pressure, in the process, the tapered cutter head 401 moves close to the limiting washer 402 and extrudes the supporting spring A403, the supporting spring A403 is elastically deformed and compressed, and the tapered cutter head 401 moves upward through the supporting spring B to drive the connecting shaft 405 to move upward, the connecting shaft 405 drives the blocking sleeve 404 to synchronously rise in the process of moving upward, at this time the upper and lower sides of the limiting washer 402 are in a conductive state, the pump body 2033 is controlled to operate, the pump body 2033 injects the pumped cooling liquid into the adapter sleeve 2031 through the inlet pipe 2032, the cooling liquid in the adapter sleeve 2031 enters the bridge groove through the bridge hole A202, and then flows into the cooling liquid outlet hole A205, and finally flows into the plurality of cooling liquid spray heads 601 through the plurality of bridge holes B602, and the cooling liquid is sprayed out of the plurality of cooling liquid spray heads 601 and acts on the groove on the hydrogen energy power device accessory;

[0054] The tapered cutter head 401 is retracted to the maximum extent, at which time the ball 707 is located in the concave groove, and the cooling liquid flowing through the fin wheel 702 drives the fin wheel 702 to rotate, and the rotation of the fin wheel 702 drives the plurality of balls 707 to rotate. During the rolling out of the ball 707 from the concave groove, the ball 707 and the limiting ring 703 generate extrusion force and gradually increase. Under the action of the extrusion force, the connecting shaft 405 goes down and extrudes the supporting spring B to cause elastic deformation. During the process of the ball 707 gradually rolling into the concave groove, the supporting spring B begins to recover the deformation, thereby pushing the connecting shaft 405 to go up. The reciprocating lifting action of the connecting shaft 405 drives the adapter 604 to move synchronously, thereby enabling the cooling liquid injection head 601 to perform the pitching action.

[0055] Working principle, in use:

[0056] First, install the adapter 201 to the drilling machine body 1, and then install the drill bit body 204 into the adapter 201. Control the drilling machine body 1 to operate, and the drilling machine body 1 drives the drill bit body 204 to rotate at high speed through the adapter 201, and at the same time drives the drill bit body 204 to move close to the hydrogen energy power device accessory fixed on the machining table 3. When the tapered cutter head 401 contacts the hydrogen energy power device accessory, the drill bit body 204 is still located above the hydrogen energy power device accessory at this time;

[0057] The drilling machine body 1 continues to drive the drill bit body 204 to go down, and the pressure between the tapered cutter head 401 and the hydrogen energy power device accessory gradually increases. Under the action of the pressure, the tapered cutter head 401 retracts into the cooling liquid outlet hole A 205. In this process, the tapered cutter head 401 moves close to the limiting washer 402 and extrudes the supporting spring A 403, and the supporting spring A 403 is compressed and deformed elastically. In the process of the tapered cutter head 401 going up, the supporting spring B drives the connecting shaft 405 to go up, and the connecting shaft 405 drives the blocking sleeve 404 to rise synchronously. At this time, the upper and lower sides of the limiting washer 402 are in a conductive state. Control the pump body 2033 to operate, and the pump body 2033 injects the pumped cooling liquid into the adapter sleeve 2031 through the inlet pipe 2032. The cooling liquid in the adapter sleeve 2031 enters the bridge groove through the bridge hole A 202, and then flows into the cooling liquid outlet hole A 205. Finally, the cooling liquid flows into the plurality of cooling liquid injection heads 601 through the plurality of bridge holes B 602, respectively. The cooling liquid is sprayed out of the plurality of cooling liquid injection heads 601 and acts on the groove machined on the hydrogen energy power device accessory. The sprayed cooling liquid directly acts on the drill bit body 204 and the machining surface, which can quickly cool the drill bit body 204 and the machining surface, and also effectively remove burrs on the machining surface. The burrs carried by the cooling liquid flow out of the groove machined on the hydrogen energy power device accessory along the spiral groove on the surface of the drill bit body 204;

[0058] The taper tool head 401 is retracted to the maximum extent, at which time the ball 707 is located in the concave groove, and the cooling liquid flowing through the fin wheel 702 drives the fin wheel 702 to rotate, and the rotation of the fin wheel 702 drives the plurality of balls 707 to rotate. In the process of the ball 707 rolling out of the concave groove, the extrusion force between the ball 707 and the limiting ring 703 is generated and gradually increased. Under the action of the extrusion force, the connecting shaft 405 descends and extrudes the supporting spring B to cause elastic deformation. In the process of the ball 707 gradually rolling into the concave groove, the supporting spring B begins to recover the deformation, thereby pushing the connecting shaft 405 to ascend. The reciprocating lifting action of the connecting shaft 405 drives the adapter 604 to move synchronously, so that the cooling liquid injection head 601 can be driven to perform the pitching action. By changing the injection angle of the cooling liquid injection head 601, the cooling liquid injected at multiple injection angles can better remove burrs and avoid the retention of burrs.

[0059] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacements or changes to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.

A combined processing machine tool for a hydrogen energy power plant according to claim 1, characterized in that: The coolant inlet (203) comprises an adapter sleeve (2031) sleeved on the periphery of the docking head (201); a sealing bearing (2034) is rotatably connected between the adapter sleeve (2031) and the docking head (201); an inlet pipe (2032) is clamped on the outer wall of the adapter sleeve (2031); a pump body (2033) is installed on the drilling machine body (1); and the other end of the inlet pipe (2032) is installed at the output port of the pump body (2033).

3. A method for using the combined processing machine tool for a hydrogen energy power plant according to any one of claims 1-2, characterized in that: The following steps are involved: First, the docking joint (201) is installed on the drilling machine body (1), and then the drill bit body (204) is installed in the docking joint (201). The drilling machine body (1) is controlled to operate. The drilling machine body (1) drives the drill bit body (204) to rotate at a high speed through the docking joint (201), and at the same time drives the drill bit body (204) to approach the hydrogen energy power device accessory fixed on the processing table (3). When the conical cutter head (401) comes into contact with the hydrogen energy power device accessory, the drill bit body (204) is still located above the hydrogen energy power device accessory; The drilling machine body (1) continues to drive the drill bit body (204) downward, and pressure is generated between the conical cutter head (401) and the hydrogen energy power device accessories and gradually increases. Under the action of the pressure, the conical cutter head (401) retracts into the coolant outlet hole A (205). During this process, the conical cutter head (401) approaches the limit washer (402) and squeezes the support spring A (403). The support spring A (403) undergoes elastic deformation and is compressed. During the upward process, the conical cutter head (401) also drives the connecting shaft (405) upward through the supporting spring B. During the upward process, the connecting shaft (405) drives the sealing sleeve ( 404) rises synchronously, at which time the upper and lower sides of the limit washer (402) are in a conducting state, controlling the operation of the pump body (2033), and the pump body (2033) injects the sucked coolant into the adapter sleeve (2031) through the inlet pipe (2032), and the coolant entering the adapter sleeve (2031) enters the bridge groove through the bridge hole A (202), and then flows into the coolant outlet hole A (205), and finally flows into the multiple coolant injection heads (601) respectively through the multiple bridge holes B (602), and the coolant is ejected through the multiple coolant injection heads (601) to act on the groove body processed on the hydrogen energy power device accessories; The conical cutter head (401) retracts to the maximum extent, at which time the ball (707) is located in the concave groove, and the coolant flowing through the fin wheel (702) drives the fin wheel (702) to rotate, and the rotation of the fin wheel (702) drives the multiple balls (707) to rotate. In the process of the ball (707) rolling out of the concave groove, an extrusion force is generated between the ball (707) and the limit ring (703) and gradually increases. Under the action of the extrusion force, the connecting shaft (405) moves downward and squeezes the support spring B to cause it to undergo elastic deformation. In the process of the ball (707) gradually rolling into the concave groove, the support spring B begins to recover its deformation, thereby pushing the connecting shaft (405) upward, and utilizing the reciprocating lifting action of the connecting shaft (405) to drive the adapter (604) to move synchronously, thereby being able to drive the coolant injection head (601) to perform a pitching action.
