Description

Technical Field

[0001] The present invention relates to the technical field of modular machine tools, and particularly to a drilling device for a generator end cover. Background Art

[0002] A generator is a device that converts other forms of energy into electrical energy. It operates based on the law of electromagnetic induction and mainly consists of a stator and a rotor. The output electrical energy can be adjusted in parameters and then transmitted to various power consumption sites to meet the power consumption requirements.

[0003] A patent with the application number CN202410362330.9 discloses a drilling device for a generator end cover, including a main body mechanism. Columns are symmetrically arranged at the top of the main body mechanism, and a top plate is fixedly connected to the top of the columns. Active rollers are evenly arranged on the inner wall of the main body mechanism close to the columns, guide rods are symmetrically arranged on the inner wall of the main body mechanism, and a groove is formed inside the main body mechanism. It also includes a drilling mechanism for drilling and grinding the generator end cover, where the top of the drilling mechanism is fixedly connected to the bottom of the top plate, and an adjustment mechanism for adjusting the position of the generator end cover to cooperate with the drilling mechanism for drilling and grinding.

[0004] An end cover is provided at the tail of the generator. During the production process of the end cover, drilling is required. Existing equipment for drilling the end cover uses cutting fluid to cool the drilling. However, the drilling transports the generated debris upward, which causes the cutting fluid flowing from the top to the drill bit to not cool the drill bit well. The drill bit is prone to wear due to poor heat dissipation, and when a large number of end covers are drilled, the excessive wear of the drill bit will affect the processing speed. Summary of the Invention

A cleaning pool is fixedly connected to the top of the equipment base on the right side of the moving robotic arm. Two fixing clips are fixedly connected to the top of the drill bit.

[0012] Preferably, a storage box is fixedly connected to the top of the equipment base. A first hydraulic pump is fixedly connected to the top of the storage box. A first connecting pipe is fixedly connected to the top of the first hydraulic pump. The first connecting pipe is fixedly connected to the bottom of the impact tube.

[0013] Preferably, a notch is provided on the outer wall of the return hood on the front side of the filter cover. A receiving structure is provided at the bottom of the notch. The bottom of the moving platform is movably connected to a rotating frame through a bearing. A sweeping plate is fixedly connected to the bottom of the rotating frame. A driving motor is fixedly connected to the bottom of the drill bit. Tooth patterns meshing with the driving motor are provided on the outer wall of the rotating frame.

[0014] Preferably, the top cooling mechanism includes fixed telescopic rods, which are fixedly connected to the bottom of the driving box. A first spring is fixedly connected to the bottom of the fixed telescopic rods. A sealing cover is fixedly connected to the bottom of the fixed telescopic rods. The drill bit is located inside the sealing cover. A rubber ring is fixedly connected to the bottom of the sealing cover. A second connecting pipe is fixedly connected to the outer wall of the sealing cover. A second hydraulic pump is fixedly connected to the top of the storage box. The top of the second hydraulic pump is fixedly connected to the second connecting pipe.

[0015] Preferably, a rotating plate is movably connected to the bottom of the second connecting pipe inside the sealing cover through a bearing. A pushing foot is fixedly connected to the bottom of the rotating plate.

[0016] Preferably, when the second hydraulic pump has liquid flowing into the sealing cover, the liquid will pass through the rotating plate, and at the same time, the liquid will pass through the moving rotating plate, causing the rotating plate to rotate around the axis of the drill bit.

[0017] Preferably, a pressure relief pipe is fixedly connected to the outer wall of the sealing cover. A second spring is fixedly connected to the inside of the pressure relief pipe. A pressure relief piece is fixedly connected to the inside of the second spring. The pressure relief piece is movably connected to the inside of the pressure relief pipe. An opening is provided on the outside of the pressure relief pipe at the bottom of the pressure relief piece.

[0018] The present invention provides a generator end cap drilling device, which has the following beneficial effects:

[0019] 1. For this generator end - cover drilling device, liquid will continuously spray out from the top of the impact pipe. The sprayed liquid will impact the bottom of the end - cover. Since the generator end - cover is made of metal liquid with good heat conduction, when the drill bit drills, heat will also be transferred to the bottom of the generator end - cover. The flowing liquid at the bottom of the end - cover can better dissipate heat from the end - cover, thereby cooling the drill bit working inside the end - cover. And the returned liquid will flow back into the storage tank through the return pipe at the bottom of the return cover for circulating cooling, which can reduce the wear of the drill bit and improve the processing speed.

[0020] 2. For this generator end - cover drilling device, the liquid inside the storage tank is sent into the sealing cover through the second connecting pipe, making the inside of the sealing cover full of liquid. The liquid will fit more closely to the drill bit. When the drill bit drills, heat will also be transferred to the rest of the drill bit, thus cooling the drill bit. At the same time, when the driving foot rotates, the debris around the drilled hole will be swept to the edge by centrifugal force, avoiding the debris from accumulating at the drilled hole. Due to the cooling effect on the drill bit, it can reduce the wear of the drill bit and improve the processing speed of crushing.

[0021] 3. For this generator end - cover drilling device, when the drilling is completed, the moving platform descends, allowing the liquid discharged from the impact pipe to pass through the drilled hole. Since the drilled hole is blocked by the liquid discharged from the impact pipe, the liquid discharged from the impact pipe will mix with the liquid discharged from the second connecting pipe and flow around from the top of the generator end - cover, washing down the debris generated from drilling at the top of the generator end - cover. Then, the moving robotic arm will put the drilled end - cover into the cleaning pool for cleaning, which can save the time for cleaning the debris attached to the surface of the end - cover and indirectly improve the processing speed.

Specific embodiments

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0035] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0036] Embodiment 1: Please refer to Figures 1-7 , the present invention provides a technical solution: a drilling device for the end cover of a generator, including an equipment base 1, a fixed column 2 fixedly connected to the top of the equipment base 1, a drive box 3 fixedly connected to the top of the fixed column 2, a drill bit 41 movably connected to the bottom of the drive box 3, a moving platform 42 movably connected to the outer wall of the fixed column 2, a bottom cooling and flushing mechanism 5 fixedly connected to the bottom of the moving platform 42, and a top cooling mechanism 6 fixedly connected to the bottom of the drive box 3;

[0037] The bottom cooling and flushing mechanism 5 includes:

[0038] Filter cover 501, which is fixedly connected to the bottom of the mobile platform 42;

[0039] Return flow cover 502, which is fixedly connected to the bottom of the filter cover 501;

[0040] Impact pipe 503, which is fixedly connected inside the filter cover 501 and located at the bottom of the mobile platform 42.

[0041] Place the generator end cover to be drilled on the top of the conveyor belt 44, and the conveyor belt 44 will transport the generator end cover to the top of the mobile platform 42.

[0042] On the left side of the mobile platform 42, there is a fixedly connected conveyor belt 44. At the bottom of the conveyor belt 44, there is a fixedly connected telescopic rod, and the telescopic rod can extend and retract following the up and down movement of the mobile platform 42. On the top of the mobile platform 42 and to the right of the fixed column 2, there is a fixedly connected mobile robotic arm 45, which can move the end cover after drilling. On the top of the equipment base 1 and to the right of the mobile robotic arm 45, there is a fixedly connected cleaning tank 46. Inside the cleaning tank 46, there is a liquid capable of cleaning the drilled parts. At the top of the drill bit 41, there are two fixedly connected fixing clamps 43.

[0043] The two fixing clamps 43 extend inward to clamp and fix the generator end cover. Then, the mobile platform 42 moves upward along the mobile platform 42, and the drive box 3 drives the drill bit 41 to rotate to drill the generator end cover. After drilling, the fixing clamps 43 release the fixation, and the mobile robotic arm 45 moves the mobile platform 42 into the cleaning tank 46 to clean the generator end cover.

[0044] On the top of the equipment base 1, there is a fixedly connected storage tank 504. Inside the 504, there is stored cutting fluid. On the top of the storage tank 504, there is a fixedly connected first hydraulic pump 505. On the top of the first hydraulic pump 505, there is a fixedly connected first connecting pipe 506, and the first connecting pipe 506 is fixedly connected to the bottom of the impact pipe 503. At the bottom of the return flow cover 502, there is a fixedly connected return pipe 507, and the bottom of the return pipe 507 is fixedly connected to the storage tank 504.

[0045] When drilling, the first hydraulic pump 505 will send the liquid inside the storage tank 504 through the first connecting pipe 506 into the impact pipe 503. The top of the impact pipe 503 will continuously spray out the liquid, and the sprayed liquid will impact the bottom of the end cover. Part of the liquid will enter the top of the mobile platform 42, and then through the mobile platform 42, it will flow back into the return flow cover 502 after passing through the filter cover 501. There is also part of the liquid that will directly fall back into the return flow cover 502. The returned liquid will flow back into the storage tank 504 through the return pipe 507 at the bottom of the return flow cover 502.

[0046] A notch is provided on the outer wall of the reflux hood 502 at the front of the filter hood 501, and a receiving structure is provided at the bottom of the notch. The bottom of the moving platform 42 is movably connected to the rotating frame 508 through a bearing. The bottom of the rotating frame 508 is fixedly connected to the sweeping plate 509. The bottom of the drill bit 41 is fixedly connected to the driving motor 510. Tooth patterns meshing with the driving motor 510 are provided on the outer wall of the rotating frame 508.

[0047] When the liquid on the top of the moving platform 42 flows into the top of the filter hood 501 through the opening on the moving platform 42, it will be filtered by the filter hood 501, so that some debris mixed in the liquid is isolated on the top of the filter hood 501. At the same time, the rotating frame 508 will be driven to rotate by the driving motor 510 through the tooth patterns provided on the outer wall. The sweeping plate 509 at the bottom of the rotating frame 508 will rotate synchronously, sweep the debris out of the top of the filter hood 501 through the notch, and let the debris fall into the receiving structure through the notch for collection.

[0048] Embodiment 2: Please refer to Figures 1-11 , based on Embodiment 1, the present invention provides a technical solution:

[0049] The top cooling mechanism 6 includes a fixed telescopic rod 601, which is fixedly connected to the bottom of the driving box 3. The bottom of the fixed telescopic rod 601 is fixedly connected to a first spring 602. The bottom of the fixed telescopic rod 601 is fixedly connected to a sealing cover 603. The drill bit 41 is located inside the sealing cover 603. A rubber ring 606 is fixedly connected to the bottom of the sealing cover 603. A second connecting pipe 611 is fixedly connected to the outer wall of the sealing cover 603. The top of the storage tank 504 is fixedly connected to a second hydraulic pump 610, and the top of the second hydraulic pump 610 is fixedly connected to the second connecting pipe 611.

[0050] When drilling, the moving platform 42 moves upward, which will make the bottom of the rubber ring 606 stick to the top of the generator end cover. Then, when the moving platform 42 continues to rise, the moving platform 42 will push the sealing cover 603 upward through the generator end cover, causing the fixed telescopic rod 601 and the first spring 602 to contract. At the same time, the second hydraulic pump 610 sends the liquid inside the storage tank 504 into the sealing cover 603 through the second connecting pipe 611, filling the inside of the sealing cover 603 with liquid and allowing the drill bit 41 to drill the generator end cover.

[0051] A rotating plate 604 is movably connected to the bottom of the second connecting pipe 611 inside the sealing cover 603 through a bearing, and a pushing foot 605 is fixedly connected to the bottom of the rotating plate 604.

[0052] When the second hydraulic pump 610 has liquid flowing into the sealing cover 603, the liquid will pass through the rotating plate 604, and at the same time, the liquid will pass through the moving rotating plate 604, causing the rotating plate 604 to rotate around the axis of the drill bit 41.

[0053] When the liquid flow inside the second connecting pipe 611 enters the inside of the sealing cover 603, the liquid inside the sealing cover 603 will pass through the rotating plate 604, thereby driving the rotation of the rotating plate 604. The rotating plate 604 drives the bottom pushing feet 605 to rotate. The rotation of the pushing feet 605 continuously sweeps the periphery of the drill hole, and the debris around the drill hole is swept to the edge by centrifugal force, avoiding the accumulation of drill hole debris near the drill bit 41 and affecting heat dissipation.

[0054] When the drilling is completed, the moving platform 42 descends, allowing the liquid discharged from the impact pipe 503 to pass through the drilled hole. At the same time, the liquid discharged from the second connecting pipe 611 directly flows downward to the top of the generator end cover. Since the drilled hole is blocked by the liquid discharged from the impact pipe 503, the liquid discharged from the impact pipe 503 and the liquid discharged from the second connecting pipe 611 are mixed with each other and flow around from the top of the generator end cover, playing a role in flushing the top of the generator end cover, flushing down the debris generated by drilling the top of the generator end cover, and then flowing back into the inside of the return cover 502 through the moving platform 42.

[0055] A pressure relief pipe 607 is fixedly connected to the outer wall of the sealing cover 603. A second spring 609 is fixedly connected inside the pressure relief pipe 607. A pressure relief piece 608 is fixedly connected to the inner side of the second spring 609. The pressure relief piece 608 is movably connected inside the pressure relief pipe 607. An opening is provided on the outside of the pressure relief pipe 607 at the bottom of the pressure relief piece 608.

[0056] When the inside of the sealing cover 603 is filled with liquid, the continuous injection of liquid by the second connecting pipe 611 will increase the pressure inside the sealing cover 603. The increased pressure inside the sealing cover 603 will push the pressure relief piece 608 outward, thereby compressing the second spring 609. After the pressure relief piece 608 is pushed, the liquid inside the sealing cover 603 will be discharged through the opening of the pressure relief pipe 607.

[0057] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
