Description

Technical Field

[0001] The present invention belongs to the technical field of combined processing of hydrogen energy power devices, and in particular relates to a combined processing machine tool and method for hydrogen energy power devices. Background Art

[0002] The processes for processing hydrogen energy power unit accessories include corner cutting, punching, rough turning, lathe finishing, five-axis surface machining and the final chrome plating process. Each process requires different processing equipment for processing. The combined machine tool is based on serialized and standardized general components, equipped with special components and fixtures designed according to the specific shape of the workpiece and the processing technology. It is a semi-automatic or automatic special-purpose machine tool. It generally adopts multi-axis, multi-tool, multi-process, multi-surface or multi-station simultaneous processing. The production efficiency is several to dozens of times higher than that of general-purpose machine tools, which can effectively improve the processing efficiency of hydrogen energy power unit accessories.

[0003] The prior art discloses some invention patents in the field of combined processing technology of hydrogen energy power devices, among which the invention patent with publication number CN115156923A discloses a combined processing machine tool for hydrogen energy power devices, including an integrated combined processing body, a sheet metal efficient rough cutting mechanism, a multi-axis curved surface deburring mechanism and a hidden chrome plating mechanism. The sheet metal efficient rough cutting mechanism is arranged at the upper end inside the integrated combined processing body, the multi-axis curved surface deburring mechanism is arranged in the integrated combined processing body, and the hidden chrome plating mechanism is arranged on the integrated combined processing body. This technical solution proposes a sheet metal efficient rough cutting mechanism, a multi-axis curved surface deburring mechanism and a hidden chrome plating mechanism. Through the mutual cooperation between the mechanisms, the labor cost is effectively reduced and the processing efficiency is improved.

[0004] The prior art discloses some invention patents in the field of combined processing technology of hydrogen energy power devices, among which the invention patent with announcement number CN118650439B discloses a drilling and tapping combined machine tool that can chamfer on both sides. It includes a base, a placement frame, a lifting frame, a chamfering tool I, an electric slide rail, a rotating frame, a dual-axis motor, etc. The placement frame is connected to the top surface of the base, the lifting frame is arranged on the top surface of the base, and the lifting frame is located below the placement frame. The chamfering tool I is symmetrically rotated and installed on the top surface of the lifting frame. The electric slide rail is slidably installed on the placement frame. The rotating frame is rotatably connected to the slider of the electric slide rail. The dual-axis motor is symmetrically connected in the rotating frame. The drill body of the technical solution continues to move downward after drilling the workpiece, which can enable the chamfering tool II to automatically chamfer the entrance of the drill hole. Then, when the drill body rises and switches the direction of the tap, the chamfering tool I can rise accordingly and automatically chamfer the exit of the drill hole. In this way, both sides of the drill hole can be automatically chamfered, which can prevent burrs from causing harm to workers, and no manual operation is required by workers, thereby improving processing efficiency.

[0005] In summary, it can be seen that the combined processing machine tools that can be used for the processing of hydrogen energy power plant accessories still have some shortcomings during use. Drilling and deburring still use traditional distributed processing technology. The distribution of drilling and deburring limits the production efficiency of the combined processing machine tools, and the burrs are easy to scratch the processing surface during the rapid rotation of the drill body, thereby affecting the processing accuracy.

[0006] Based on this, the present invention designs a hydrogen energy power device combined processing machine tool and method to solve the above problems. Summary of the invention

[0015] A limiting gasket is clamped above the corresponding conical cutter head in the coolant outlet hole B, and a supporting spring A is connected under the limiting gasket. The limiting gasket is elastically supported and connected to the conical cutter head through the supporting spring A. A sealing sleeve for sealing is sleeved in the limiting gasket, and a connecting shaft is fixedly sleeved in the sealing sleeve. A supporting spring B is connected to the end of the connecting shaft, and the connecting shaft is elastically supported and connected to the bottom wall of the inner cavity of the conical cutter head through the supporting spring B.

[0016] As a further description of the above technical solution:

[0017] An elastic gasket is clamped in the port of the coolant outlet hole B, and a coolant injection assembly A and a coolant injection assembly B are sleeved in the elastic gasket on the conical cutter head. The coolant injection assembly B has the same structure as the coolant injection assembly A and is used to change the coolant injection angle.

[0024] A method for using a combined processing machine tool for a hydrogen energy power device comprises the following steps:

[0025] First, install the butt joint onto the drilling machine body, then install the drill bit body into the butt joint, control the operation of the drilling machine body, and the drilling machine body drives the drill bit body to rotate at high speed through the butt joint, and at the same time drives the drill bit body to approach the hydrogen energy power device accessories fixed on the processing table. When the conical cutter head contacts the hydrogen energy power device accessories, the drill bit body is still located above the hydrogen energy power device accessories;

[0026] The drilling machine body continues to drive the drill body downward, and pressure is generated and gradually increased between the conical cutter head and the hydrogen energy power device accessories. The conical cutter head retracts into the coolant outlet hole A under the action of pressure. During this process, the conical cutter head approaches the limit washer and squeezes the support spring A. The support spring A undergoes elastic deformation and is compressed. The conical cutter head also drives the connecting shaft upward through the support spring B during the upward process. The connecting shaft drives the sealing sleeve to rise synchronously during the upward process. At this time, the upper and lower sides of the limit washer are in a conducting state to control the operation of the pump body. The pump body injects the sucked coolant into the adapter sleeve through the inlet pipe. The coolant entering the adapter sleeve enters the bridge groove through the bridge hole A, and then flows into the coolant outlet hole A, and finally flows into the multiple coolant injection heads through multiple bridge holes B. The coolant is sprayed out through the multiple coolant injection heads to act on the groove body processed on the hydrogen energy power device accessories;

[0027] The conical cutter head retracts to the maximum extent, at which time the ball is located in the concave groove, and the coolant flowing through the fin wheel will drive the fin wheel to rotate, and the rotation of the fin wheel drives multiple balls to rotate. In the process of the ball rolling out of the concave groove, an extrusion pressure is generated between the ball and the limit ring and gradually increases. Under the action of the extrusion pressure, the connecting shaft moves downward and squeezes the support spring B to cause it to undergo elastic deformation. In the process of the ball gradually rolling into the concave groove, the support spring B begins to recover its deformation, thereby pushing the connecting shaft upward, and utilizing the reciprocating lifting action of the connecting shaft to drive the synchronous action of the adapter, thereby being able to drive the coolant spray head to perform a pitch action.

[0028] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0029] 1. In the present invention, the reciprocating lifting action of the connecting shaft is used to drive the adapter to move synchronously, thereby driving the coolant spray head to do a pitching action. By changing the spray angle of the coolant spray head, the coolant sprayed at a variety of spray angles can better remove burrs and avoid the retention of burrs.

[0030] 2. In the present invention, the coolant flows into multiple coolant injection heads through multiple bridging holes B respectively, and the coolant is sprayed through multiple coolant injection heads to act on the groove body processed on the hydrogen energy power device accessories. The sprayed coolant directly acts on the drill bit body and the processing surface, which can quickly cool the drill bit body and the processing surface, and can also effectively remove burrs on the processing surface. The coolant carries the burrs along the spiral groove on the surface of the drill bit body and flows out of the groove body processed on the hydrogen energy power device accessories.

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

[0052] First, the docking head 201 is installed on the drilling machine body 1, and then the drill bit body 204 is installed in the docking head 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 head 201, and at the same time drives the drill bit body 204 to approach the hydrogen energy power device accessories fixed on the processing table 3. When the conical cutter head 401 comes into contact with the hydrogen energy power device accessories, the drill bit body 204 is still located above the hydrogen energy power device accessories;

[0053] 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. The conical cutter head 401 retracts into the coolant outlet hole A205 under the action of pressure. During this process, the conical cutter head 401 approaches the limit washer 402 and squeezes the support spring A403. The support spring A403 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 4 04 rises synchronously, at this 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 A202, and then flows into the coolant outlet hole A205, and finally flows into the multiple coolant injection heads 601 through multiple bridge holes B602, and the coolant is sprayed out through the multiple coolant injection heads 601 to act on the groove body processed on the hydrogen energy power device accessories;

[0054] 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. 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 pressure is generated between the ball 707 and the limit ring 703 and gradually increases. Under the action of the extrusion pressure, the connecting shaft 405 moves downward and squeezes the supporting spring B to cause it to undergo elastic deformation. In the process of the ball 707 gradually rolling into the concave groove, the supporting 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 spray head 601 to perform a pitch action.

[0055] Working principle, when using:

[0056] First, the docking head 201 is installed on the drilling machine body 1, and then the drill bit body 204 is installed in the docking head 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 head 201, and at the same time drives the drill bit body 204 to approach the hydrogen energy power device accessories fixed on the processing table 3. When the conical cutter head 401 comes into contact with the hydrogen energy power device accessories, the drill bit body 204 is still located above the hydrogen energy power device accessories;

[0057] 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 accessories of the hydrogen energy power device and gradually increases. The conical cutter head 401 retracts into the coolant outlet hole A205 under the action of pressure. During this process, the conical cutter head 401 approaches the limit washer 402 and squeezes the support spring A403. The support spring A403 undergoes elastic deformation and is compressed. During the upward process, the conical cutter head 401 also drives the connecting shaft 405 upward through the support spring B. During the upward process, the connecting shaft 405 drives the sealing sleeve 404 to rise synchronously. At this 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 draws the sucked coolant through the guide The inlet pipe 2032 is injected into the adapter sleeve 2031. The coolant entering the adapter sleeve 2031 enters the bridge groove through the bridge hole A202, then flows into the coolant outlet hole A205, and finally flows into the multiple coolant injection heads 601 through multiple bridge holes B602. The coolant is sprayed out through the multiple coolant injection heads 601 to act on the groove body processed on the hydrogen energy power device accessories. The sprayed coolant directly acts on the drill bit body 204 and the processed surface, which can quickly cool the drill bit body 204 and the processed surface, and can also effectively remove burrs on the processed surface. The coolant carries the burrs along the spiral groove on the surface of the drill bit body 204 and flows out of the groove body processed on the hydrogen energy power device accessories;

[0058] 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 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 supporting spring B to cause it to undergo elastic deformation. In the process of the ball 707 gradually rolling into the concave groove, the supporting spring B begins to recover its deformation, thereby pushing the connecting shaft 405 upward, and the reciprocating lifting action of the connecting shaft 405 drives the adapter 604 to move synchronously, thereby driving the coolant spray head 601 to do a pitch action, and by changing the spray angle of the coolant spray head 601, the coolant sprayed at a variety of spray angles can better remove burrs and avoid the retention of burrs.

8. A method for using the combined processing machine tool for a hydrogen energy power plant according to any one of claims 1 to 7, characterized in that: The following steps are involved: First, the docking head (201) is mounted on the drilling machine body (1), and then the drill head body (204) is mounted in the docking head (201). The drilling machine body (1) is controlled to operate, and the drilling machine body (1) drives the drill head body (204) to rotate at a high speed through the docking head (201). At the same time, the drill head body (204) is driven 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 head 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) through the multiple bridge holes B (602), and the coolant is sprayed out 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. 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 pitch action.
