Description

Technical Field

[0001] The present invention relates to the technical field of drilling equipment, and in particular to a drilling equipment for processing coupling flanges. Background Art

[0002] As a key component connecting two shafts in a mechanical transmission system, the coupling flange achieves high-precision docking and torque transmission through precise bolt holes. Its main body materials are mostly metals such as steel or cast iron, and it needs to withstand high-intensity torque and vibration. During the manufacturing process, the hole machining of the coupling flange is particularly crucial, and the symmetry and spacing accuracy of the holes directly affect the assembly stability and reliability.

[0003] Currently, the production of coupling flanges usually combines numerical control machine tools with positioning jigs and uses laser calibration technology for assistance to achieve efficient and precise batch machining of evenly distributed holes. For example, a drilling device for processing flanges with the authorization announcement number CN220347234U effectively fixes the coupling flange by using an adjustable jig, thereby improving the overall drilling efficiency and accuracy. However, in practical applications, this device has some limitations: during operation, the workpiece needs to be placed in the clamping component for fixation first, and then the drill bit is controlled to slowly descend to complete the drilling operation. During this process, in order to lubricate and cool the drill bit, cutting fluid needs to be intermittently sprayed. As the number of drilled holes increases, the generated debris also increases. Since the working platform of the device is in a horizontal state, the debris is not easily separated from the workpiece naturally, affecting the machining environment of a single workpiece. Even more, the flushing effect of the cutting fluid instead enhances the adhesion of the debris on the workpiece surface. When replacing the workpiece, the residual debris is easily adhered to the clamping component, which not only reduces the clamping stability of the subsequent workpiece but also affects the overall machining quality.

[0004] In view of the above problems, it is necessary to propose a drilling equipment for processing coupling flanges that effectively optimizes the clamping method and improves the debris treatment mechanism to improve the machining quality and efficiency. Summary of the Invention

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a drilling equipment for processing coupling flanges that effectively optimizes the clamping method and improves the debris treatment mechanism.

[0006] The technical solution is as follows: A drilling equipment for processing coupling flanges, comprising:

[0007] A processing platform;

[0008] An outer cylinder, arranged in the middle of the top of the processing platform, an electric gear is installed inside the outer cylinder, a toothed ring meshing with the electric gear rotates on the inner wall of the outer cylinder, and a rotating ring connected to the toothed ring rotates on the outer wall of the outer cylinder;

[0009] The placement plates are arranged on the rotating ring in a circumferentially spaced and inclined manner. Bumps for clamping the flange body are provided on each placement plate. Electric slide rails are installed at one end of each placement plate close to the outer cylinder. An extension plate is connected to the slider of each electric slide rail, and a baffle plate matching the position of the corresponding bump is inserted at the end of the extension plate.

[0010] The drilling machine is arranged on the processing platform and aligned with one side of the placement plate.

[0011] The liquid storage frame is arranged on the processing platform and below the drilling machine. Liquid infusion pumps are symmetrically installed on the liquid storage frame. A spray pipe is connected to the liquid outlet of each liquid infusion pump. A U-shaped pipe that abuts against the corresponding extension plate is connected between the ends of the spray pipes. Connecting rods that abut against and are slidably connected to one side of the housing of the drilling machine are respectively fixed on both sides of the spray pipes, so that the spray pipes cooperate with the drilling machine to lift and lower, and the nozzles of the spray pipes are flush with the corresponding placement plates.

[0012] Preferably, an inlet pipe is further included. An inlet pipe extending into the liquid storage frame is connected to the inlet of each liquid infusion pump. A set of guide plates is arranged on both inner walls of the liquid storage frame. A filter frame with a floating block at the top slides between the guide plates on the same side, and the ends of the inlet pipes are all placed inside the filter frame on the same side.

[0013] Preferably, a centralized frame is further included. A centralized frame connected to the liquid storage frame is arranged on the processing platform. A wind guide frame is connected to one side of the centralized frame away from the outer cylinder. An upright frame is also arranged on the processing platform. Hair dryers with air outlets facing the flange body after drilling are symmetrically arranged on the upright frame.

[0014] Preferably, a mounting frame is further included. A mounting frame is arranged on the processing platform on the other side of the centralized frame. Rotating frames are rotatably arranged on the mounting frame in a vertically symmetric layout. Three grinding wheels are rotatably arranged at intervals on both sides of each rotating frame, and a driving component for driving the corresponding grinding wheels to operate is built in the rotating frame; a driving motor is also installed on the mounting frame. A worm gear is arranged at each end of the two rotating frames. A worm meshing with the worm gears on both sides is connected to the output end of the driving motor to drive the rotating frames to open and close.

[0015] Preferably, a cross frame is further included. A cross frame is arranged on the processing platform on the other side of the mounting frame. The cross frame is below the corresponding placement plate, and electric push rods with telescopic ends facing upward are symmetrically installed on both sides of the cross frame. A top plate for pushing the flange body after processing to discharge is connected to the telescopic ends of the electric push rods.

[0016] Preferably, the top plate is an L-shaped structure inclined outward, and pulleys are arranged in a row on the surface of the top plate in contact with the flange body.

[0017] Preferably, a diversion plate is further included. A diversion plate for guiding the flow direction of the air current is arranged on the centralized frame.

[0018] Preferably, through holes that are aligned and communicate with each other are provided on both the centralized frame and the liquid storage frame.

[0019] The present invention has the following advantages: 1. By introducing an improved clamping and spraying mechanism, the present invention uses a placement plate with bumps and a baffle plate that are inclined to achieve upper and lower clamping, making the flange body suspended around its perimeter. With the overall inclined trend, debris generated during the processing naturally slides off. In addition, the spray pipe is linked with the drilling machine through a connecting rod, enabling the nozzle of the spray pipe to automatically adjust its position according to the lifting of the drilling site, ensuring that it always remains flush with the surface of the flange body. This ensures that water can directly wash away the debris, further promoting the shedding of the debris, effectively maintaining the cleanliness of the flange body surface, reducing the impact of debris on the processing quality, and at the same time reducing the risk of debris reattachment when using cutting fluid subsequently.

[0020] 2. The present invention integrates processes such as drilling, flushing, air drying, grinding, and discharging into one, realizing a one-stop automated processing flow from drilling to finished product. This continuous and automated processing method not only significantly improves the effect after processing the flange body but also greatly improves production efficiency, providing necessary favorable conditions for the large-scale and high-efficiency production of coupling flanges.

Specific embodiments

[0032] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the attached drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside that appear or will appear in the text of the present invention are only based on the attached drawings of the present invention and do not specifically limit the present invention.

[0033] Example: A drilling device for processing a coupling flange, as Figures 1-6 shown, includes:

[0034] The processing platform 1 adopts a disc-shaped support structure, and a notch is specifically provided on the front side of the processing platform 1 to facilitate the feeding of the flange body 100.

[0035] The outer cylinder 2 is fixedly arranged in the middle of the top of the processing platform 1. An electric gear 21 is installed inside the outer cylinder 2. A toothed ring 22 that meshes with the electric gear 21 rotates on the inner wall of the outer cylinder 2. The sawteeth of the toothed ring 22 are distributed on its inner wall. A rotating ring 23 connected to the toothed ring 22 rotates on the outer wall of the outer cylinder 2. The meshing between the electric gear 21 and the toothed ring 22 provides an efficient transmission method, enabling the power to be stably transmitted from the electric gear 21 to the toothed ring 22, thereby driving the connected rotating ring 23 to rotate.

[0036] Six placing plates 3 are arranged on the rotating ring 23 at intervals in the circumferential direction. The placing plates 3 as a whole show a downward inclination trend. On each placing plate 3, there are convex blocks 31 for clamping the flange body 100 to fix the flange body 100. By cooperating with the central hole of the flange body 100 itself, it is ensured that the flange body 100 is stably placed on the placing plate 3, so that the flange bodies 100 form a circumferential arrangement layout around the rotating ring 23. On one end of each placing plate 3 close to the outer cylinder 2, there is an electric slide rail 32 installed. On the slider of the electric slide rail 32, there is a connecting plate connected. At the end of the connecting plate, there is a baffle 33 inserted, and the position of the baffle 33 matches the position of the corresponding convex block 31. Since there is a raised structure in the middle of the flange body 100, in order to ensure the complete fit of the baffle 33, the baffle 33 with an adapted size can be replaced according to the overall specifications of the workpiece. And the baffle 33 is designed as a circle as a whole. Driven by the electric slide rail 32, it can completely cover the raised part in the middle of the flange body 100, so as to cooperate with the placing plate 3 to realize the stable clamping of the flange body 100;

[0037] Specifically, by adopting the upper and lower clamping method (i.e., the placing plate 3 and the baffle 33), it is ensured that the flange body 100 remains stable during the whole processing process, avoiding position deviation caused by vibration or other factors, keeping the periphery of the drilling part of the flange body 100 suspended, and promoting the falling of the debris placed on the flange body 100 by means of the overall inclination trend of the placing position, thereby reducing the influence on the processing quality; in addition, through the above settings, the situation of excessive attachment of debris during the subsequent spraying of cutting fluid is further reduced, and the risk of adhesion between the surface of the flange body 100 and other substances is reduced, so as to ensure the cleanliness and processing accuracy of the flange body 100, and significantly improve the processing efficiency and quality of the flange body 100.

[0038] The drilling machine 4 is arranged on the processing platform 1 and aligned with one placing plate 3. The drilling part of the drilling machine 4 is perpendicular to the placing plate 3 on the same axis to ensure the accuracy and straightness of the drilling position. The drilling machine 4 has the conventional functions of multi-hole drilling and lifting, which belongs to the prior art and will not be elaborated here;

[0039] The liquid storage frame 5 is arranged on the processing platform 1 and below the drilling machine 4. On the liquid storage frame 5, there are liquid infusion pumps 51 symmetrically installed. The liquid outlet of the liquid infusion pump 51 is connected with a spray pipe 52. Between the ends of the spray pipes 52, there is a U-shaped pipe 53 that abuts against the corresponding extension plate. The U-shaped pipe 53 is in an inverted state as a whole. On both sides of the spray pipes 52, there are also connecting rods fixedly connected to and slidably connected with one side shell of the drilling machine 4, so that the spray pipes 52 cooperate with the drilling machine 4 to lift and lower. The nozzles of the spray pipes 52 are flush with the corresponding placing plate 3.

[0040] To optimize the spraying mechanism of the cutting fluid, the spray pipe 52 is connected to the drilling machine 4 through a connecting rod, enabling it to adjust its position as the drilling part of the drilling machine 4 moves up and down, so as to meet the different height requirements of the flange body 100. When the spray pipe 52 descends to a specific position, the U-shaped pipe 53 contacts and abuts against the lower extension plate, restricting the position of the two-side spray pipes 52 and keeping the nozzles flush with the surface of the flange body 100, ensuring that the cutting fluid can be directly sprayed onto the flange body 100. Then, by means of the power of the water flow, the debris attached to its surface can be effectively washed away. Combined with the overall inclined design of the device, it further promotes the rapid fall of the debris, ensuring the cleanliness of the surface of the flange body 100 and improving the processing quality and efficiency;

[0041] This optimized design effectively improves the cleaning effect during the processing by precisely controlling the position and spraying direction of the spray pipe 52, reduces the residue of debris, and ensures the drilling processing accuracy of the flange body 100.

[0042] As Figure 5 and Figure 6 shown, it also includes a liquid inlet pipe 54. The liquid inlet ports of the liquid infusion pumps 51 are all connected with the liquid inlet pipe 54 extending into the liquid storage frame 5. On the upper positions of the inner walls on both sides of the liquid storage frame 5, a group of guide plates 57 are provided. The number of a group of guide plates 57 is two and they are arranged at intervals. A filter frame 55 with a floating block 56 at the top slides between the same-side guide plates 57, and the ends of the liquid inlet pipes 54 are all placed inside the same-side filter frame 55. By placing the ends of the liquid inlet pipes 54 inside the filter frame 55, it is ensured that the cutting fluid inside the liquid storage frame 5 can be effectively filtered before entering the liquid infusion pumps 51, preventing debris and other impurities from entering the liquid infusion pumps 51, thus ensuring the cleanliness of the cutting fluid; meanwhile, under the action of the floating block 56, the filter frame 55 can automatically adjust its position with the change of the liquid level in the liquid storage frame 5 and always remain on the upper layer of the liquid surface, so that no matter how the liquid level fluctuates, the filter frame 55 maintains the best filtering position, ensuring a stable and efficient filtering effect.

[0043] As Figure 1 、 Figure 7 and Figure 8 shown, it also includes a centralized frame 6. A centralized frame 6 connected to the liquid storage frame 5 is arranged on the processing platform 1. Through holes 60 that are aligned and communicate are opened on both the centralized frame 6 and the liquid storage frame 5 for collecting the blown-off cutting fluid. A wind guide frame 61 is connected to the side of the centralized frame 6 away from the outer cylinder 2. The design of the wind guide frame 61 helps to guide the direction of the air flow. An upright frame 62 is also arranged on the processing platform 1. Hair dryers 63 with air outlets facing the flange body 100 after drilling are symmetrically arranged on the upright frame 62. The hair dryers 63 can immediately remove the residual cutting fluid on the surface of the flange body 100 after the processing is completed, ensuring the cleanliness of the flange body 100 and improving the preparation efficiency of the subsequent processing.

[0044] As Figure 7 andFigure 9 As shown, it further includes a mounting frame 7. On the processing platform 1, there is a mounting frame 7 located on the other side of the centralized frame 6. On the mounting frame 7, there are rotating frames 73 symmetrically arranged up and down. On both sides of the rotating frame 73, three grinding wheels 75 are rotatably arranged at intervals. On the processing platform 1, there is also a frame body located corresponding to the grinding wheels 75. The grinding wheels 75 respectively correspond to the hole positions at different positions of the flange body 100 to ensure the complete grinding and trimming of the flange body 100. The frame body is used to collect the impurities falling off during grinding. And inside the rotating frame 73, there is a driving component for driving the corresponding grinding wheels 75 to operate. The driving component is an external motor and a transmission component (not shown in the figure) built inside both sides of the rotating frame 73, which is used to drive each grinding wheel 75 to rotate independently. This is common prior art and will not be elaborated here. On the mounting frame 7, there is also a driving motor 71. At the ends of both rotating frames 73, there is a worm gear 74. On the output end of the driving motor 71, there is a worm 72 meshing with the worm gears 74 on both sides to drive the rotating frames 73 to open and close.

[0045] As Figure 7 and Figure 10 shown, it further includes a cross frame 8. On the processing platform 1, there is a cross frame 8 located on the other side of the mounting frame 7. The cross frame 8 is located below the corresponding placing plate 3. And on both sides of the cross frame 8, there are electric push rods 81 with their telescopic ends facing upwards symmetrically installed. On the telescopic ends of the electric push rods 81, there is a top plate 82 for pushing out the processed flange body 100. The top plate 82 is an L-shaped structure inclined outwards, which can further limit the peripheral part of the flange body 100. And on the surface of the top plate 82 contacting the flange body 100, there are pulleys arranged to assist the smooth movement of the flange body 100.

[0046] As Figure 8 shown, it further includes a drainage plate 64. On the centralized frame 6, there is a drainage plate 64 for guiding the air flow direction.

[0047] Working principle: First, place the equipment on a stable ground and ensure that the liquid storage frame 5 is filled with enough cutting fluid. Through a robotic arm or a feeding device, place the flange body 100 to be processed on the placing plate 3 at the notch, and use the convex block 31 to stably clamp the flange body 100. Then start the electric slide rail 32 to drive the baffle 33 to move downwards to form a clamping state with the corresponding placing plate 3, thereby fixing the flange body 100;

[0048] Start the electric gear 21 to engage with the toothed ring 22, drive the rotating ring 23 to rotate, and cause the flange body 100 to rotate accordingly until it is below the drilling machine 4. Then start the drilling machine 4. Its drilling part descends, and at the same time drives the connecting rod and the components thereon to move downward together until the U-shaped pipe 53 contacts the lower placement plate 3 and the two are in contact with each other, thereby restricting the positions of the spray pipes 52 on both sides. The drilling part of the drilling machine 4 continues to descend. At the same time, the connecting rod slides adaptively with the drilling machine 4 until the drill bit contacts the flange body 100 and starts the drilling operation. At this time, start the liquid infusion pump 51 to extract the cutting fluid in the liquid storage frame 5, filter it through the filter frame 55 and then flow into the liquid inlet pipe 54, and then spray it out through the spray pipes 52. Since the spray pipes 52 are flush with the flange body 100, the water flow can effectively wash away the debris and reduce adhesion. The used cutting fluid flows back to the liquid storage frame 5, is filtered again through the filter frame 55, and the floating block 56 keeps the stable input position of the filter frame 55 to ensure that the cutting fluid is always in a good state of use;

[0049] After the drilling is completed, under the driving action of the rotating ring 23, the flange body 100 is transferred above the centralized frame 6 and dried under the action of the hair dryer 63. The excess cutting fluid falls into the centralized frame 6 and flows back to the liquid storage frame 5 through the through hole 60 until the drying is completed; Subsequently, the dried flange body 100 is transferred to the next area and embedded between the two rotating frames 73. Start the driving motor 71 to drive the worm 72 to rotate, engage with the worm wheels 74 on both sides, drive the rotating frames 73 to open and close, and make the grinding wheel 75 fit the surface of the flange body 100 to polish and trim its drilling part to ensure the processing effect.

[0050] After the grinding is completed, the flange body 100 is transferred above the cross frame 8. Start the electric slide rail 32 to release the clamping restriction of the baffle 33. Then start the electric push rod 81 to extend its telescopic end, push the top plate 82 to rise and contact the flange body 100, and then lift the flange body 100. The flange body 100 is released from the restriction of the convex block 31 and slides down along the pulley of the top plate 82 to complete the discharging.

[0051] The above is only the specific implementation manner 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 can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
