Description

Technical Field

[0001] This invention relates to the field of milling technology, specifically to a milling machine for machining the keyway of a centrifugal pump shaft. Background Technology

[0002] The centrifugal pump shaft keyway milling equipment uses a rigid bed as its load-bearing foundation and integrates a worktable assembly that enables workpiece clamping, rotary indexing, and axial feed. It is equipped with a milling spindle unit that can be raised and lowered to adjust the cutting depth. The transmission system supplies the rotational power of the tool and the feed power of the workpiece. It is equipped with a clamping system that is suitable for long shaft workpieces, consisting of a center, chuck, and center frame. It also integrates tool holding, cooling and chip removal, lubrication, and electrical control related supporting structures. The whole machine completes the long keyway forming by continuous axial feed of the workpiece, and can meet the indexing milling needs of both single and multi-key slots.

[0003] In the existing technology, the overall rigidity of the milling equipment for machining the keyway of the centrifugal pump shaft is constrained by the clamping method of the long shaft during operation. When machining the slender pump shaft, cutting vibration is easily generated, which affects the surface quality and dimensional symmetry accuracy of the keyway. The structure has inherent clearance error, which is difficult to maintain in a long-term stable manner. In addition, the chips are easy to accumulate on the equipment, which can affect the movement between the parts and thus affect the machining effect of the equipment.

[0021] This invention provides a milling machine for machining the keyway of a centrifugal pump shaft. It has the following advantages:

[0022] 1. The milling equipment for machining the keyway of the centrifugal pump shaft has a first electric push rod that controls the receiving plate to drive the milling cutter to rise and fall, so that the milling cutter can fit on the workpiece, thereby realizing the milling operation. During the lifting and lowering of the component, the auxiliary rod extends and retracts with the first electric push rod to maintain the stability of the component during movement, improve the stability of the equipment during milling, maintain the milling accuracy of the equipment, and the milling frame shields metal chips to reduce chip splashing.

[0023] II. The milling equipment for machining the keyway of the centrifugal pump shaft has a shielding housing connected to a telescopic rod. Before operation, the shielding housing drives the telescopic rod to maintain a sense of verticality. When the milling cutter comes into contact with the workpiece surface, the telescopic rod retracts as the shielding housing contacts the workpiece, causing the shielding housing to move. During the milling process, the shielding housing acts to block metal chips. An outer housing is set outside the shielding housing to increase the shielding range and improve the shielding effect. Rubber blocks are set outside the outer housing to act as shock absorbers, reduce the impact pressure of chips, and reduce wear on the components. The support frame increases the rigidity of the shielding housing and maintains its stability.

[0024] 3. The milling equipment for machining the keyway of the centrifugal pump shaft adopts a funnel shell structure for the discharge shell, which guides the flow of debris and collects the debris. The guide plate increases the guiding effect of the debris, ensuring that the debris moves to the side of the discharge plate. When the discharge plate and the bottom of the discharge shell are closed, it plays the role of sealing and storing the debris. The connecting shaft is rotated by the motor, and the connecting shaft drives the discharge plate to rotate, thereby achieving the function of automatic discharge.

[0025] IV. The milling equipment for machining the keyway of the centrifugal pump shaft uses a grid plate and a perforated plate to block external and internal metal debris. The connecting housing drives the fan, which is connected to the discharge housing with an oblique structure. The fan generates air force, which is directed and unidirectionally flushed onto the machining table without the need for continuous air supply. This achieves the effect of impacting debris on the parts, reducing debris accumulation, keeping the inside of the equipment clean, and improving the debris collection effect.

[0026] 5. In the milling equipment for machining the keyway of the centrifugal pump shaft, during the movement of the component driven by the sliding block, the clamping plate comes into contact with the workpiece. The clamping plate drives the clamping support rod to compress and contract the first spring, thereby playing a role in shock absorption and buffering, reducing the clamping pressure on the component, avoiding rigid collisions between components, and maintaining the stability of the workpiece. At the same time, the first spring absorbs the amplitude of the milling process, further maintaining the stability of the workpiece. By opening tooth marks on the plate surface, the chips are guided, reducing chip residue and preventing chips from affecting the clamping effect of the component during the clamping process, thus avoiding scratches on the workpiece surface. Secondly, when the clamping plate moves with the clamping support rod, the clamping plate drives the connecting plate to slide inward into the housing groove, thereby further improving the stability of the component during movement.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] First embodiment, such as Figures 1 to 2 As shown, the present invention provides a technical solution: a milling machine for machining the keyway of a centrifugal pump shaft, comprising:

[0040] The processing table 1 has a square block structure and fixed support legs set at the bottom of the square block. A milling device 2 is fixedly connected to the center of the top of the processing table 1, and a material discharge mechanism 3 is fixedly connected to the bottom of the processing table 1 at the corresponding position of the milling device 2.

[0041] A first slot 6 is located inside the machining table 1, with openings on both sides of the machining table 1. A first guide rod 7 is fixedly connected to the inner side of the first slot 6, and a clamping device 5 is slidably connected to the outer side of the first guide rod 7. A second slot 8 is located at the center of the top of the machining table 1, with a second guide rod 9 fixedly connected to the inner side of the second slot 8. A conveying mechanism 4 is slidably connected to the outer side of the second guide rod 9. Before operation, the pump shaft is placed on the conveying mechanism 4. After the pump shaft is clamped by the conveying mechanism 4, the conveying mechanism 4 slides on the second guide rod 9 toward the milling device 2, thereby achieving automatic feeding. Then, the clamping device 5 squeezes the workpiece from both sides to fix it, preventing it from shifting during milling, thus avoiding affecting the milling effect and improving the milling quality. The milling device 2 processes the workpiece. When the equipment needs to move the tool, the clamping device 5 and the conveying mechanism 4 work together to adjust the position of the workpiece, thereby achieving the function of tool movement milling. During the milling process, a large amount of metal chips are generated on the workpiece. The discharge mechanism 3 collects and discharges the metal chips to facilitate subsequent processing. At the same time, it optimizes the working environment of the equipment and reduces the difficulty of subsequent cleaning.

[0042] A guide frame 10 is fixedly connected to the top of the processing table 1 at a position corresponding to the milling device 2. A seepage screen 11 is fixedly connected to the upper side of the inside of the guide frame 10. The guide frame 10 supports the seepage screen 11, which is used to guide and collect debris, facilitate the flow of debris, prevent the seepage screen 11 from becoming blocked, and prevent debris from falling. The blower 311 generates air force, which flushes the holes of the seepage screen 11, thereby achieving a certain cleaning effect and keeping the seepage screen 11 in continuous operation.

[0043] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 3 to 6 As shown, the milling device 2 includes:

[0044] The milling frame 201 has a T-shaped shell structure. A first electric push rod 202 is fixedly connected to the top of the inner side of the milling frame 201, and a receiving plate 203 is fixedly connected to the bottom of the first electric push rod 202.

[0045] An auxiliary rod 205 is installed outside the receiving plate 203, with its bottom fixedly connected to the bottom of the receiving plate 203. A milling cutter 204 is fixedly connected to the center of the bottom of the receiving plate 203. A first electric push rod 202 controls the receiving plate 203 to move the milling cutter 204 up and down, facilitating the milling cutter 204 to fit against the workpiece, thereby realizing the milling operation. During the lifting and lowering of the component, the auxiliary rod 205 extends and retracts with the first electric push rod 202 to maintain the stability of the component during movement, improve the stability of the equipment during milling, maintain the milling accuracy of the equipment, and the milling frame 201 shields metal chips to reduce chip splashing.

[0046] The milling device 2 also includes:

[0047] Connecting end 211 has a square block structure. A telescopic rod 206 is fixedly connected to the bottom of the connecting end 211. A shielding shell 207 is fixedly connected to the bottom of the telescopic rod 206.

[0048] The outer housing 208 has an annular housing structure. The inner side of the outer housing 208 is fixedly connected to the outer side of the shielding housing 207. A rubber block 210 is fixedly connected to the inner side of the outer housing 208, and a support frame 209 is fixedly connected to the inner side of the shielding housing 207. The shielding housing 207 is connected to the telescopic rod 206. Before operation, the shielding housing 207 drives the telescopic rod 206 to maintain a vertical feel. When the milling cutter 204 comes into contact with the workpiece surface, the telescopic rod 206 retracts after the shielding housing 207 contacts the workpiece, causing the shielding housing 207 to move. When the milling cutter 204 is machining the workpiece, the shielding housing 207 plays the role of blocking metal chips. The outer housing 208 is set outside the shielding housing 207 to increase the shielding range of the component and improve the shielding effect. The rubber block 210 is set outside the outer housing 208 to play the role of shock absorption and buffering, reducing the impact pressure of chips and reducing component wear. The support frame 209 increases the rigidity of the shielding housing 207 and maintains the stability of the housing.

[0049] The discharge mechanism 3 includes a discharge housing 301. Guide plates 302 are fixedly connected to both sides of the inner wall of the discharge housing 301. A support end 303 is fixedly connected to the bottom of the discharge housing 301. A connecting shaft 304 is rotatably connected to the inner side of the support end 303. A discharge plate 305 is fixedly connected to the outer side of the connecting shaft 304. A fixed end 306 is fixedly connected to one end of the connecting shaft 304. A motor 307 is fixedly connected to the outer side of the fixed end 306. The output end of the motor 307 is fixedly connected to one end of the connecting shaft 304. The discharge housing 301 adopts a funnel-shaped structure to guide and collect debris. The guide plates 302 enhance the guiding effect of debris, ensuring that debris moves towards the discharge plate 305. When the discharge plate 305 is closed with the bottom of the discharge housing 301, it seals and stores the debris. The motor 307 controls the rotation of the connecting shaft 304, which in turn drives the discharge plate 305 to rotate, thereby achieving automatic discharge.

[0050] The discharge housing 301 has housing slots 309 on both sides of its exterior. A connecting housing 310 is fixedly connected to the inside of each slot 309. A fan 311 is fixedly connected inside the connecting housing 310. A grating plate 312 is fixedly connected to one side of the connecting housing 310, and a perforated plate 308 is fixedly connected to the other side. The grating plate 312 and the perforated plate 308 serve to block external and internal metal debris. The connecting housing 310 drives the fan 311, which is connected to the discharge housing 301 with an oblique structure. The fan 311 generates airflow, which is directed and unidirectionally flushed onto the processing table 1 without continuous air supply. This achieves the effect of impacting debris on the parts, reducing debris accumulation, keeping the inside of the equipment clean, and improving the debris collection efficiency.

[0051] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 7 to 10 As shown, the clamping device 5 includes a clamping base 51, with a base groove 52 on the top of the clamping base 51. A sliding block 53 is slidably connected to the inner side of the base groove 52, and a clamping tool 54 is fixedly connected to the top of the sliding block 53. The sliding block 53 controls the clamping tool 54 to squeeze from both sides of the workpiece, thereby achieving the function of squeezing and clamping the workpiece to fix it, thus maintaining the stability of the workpiece, reducing the amplitude of workpiece vibration, improving the milling effect of the workpiece, and improving the processing quality of the product.

[0052] The clamping device 54 includes a clamping housing 541. Cylindrical grooves 542 are formed on both sides of the interior of the clamping housing 541. A first spring 543 is provided inside the cylindrical grooves 542. A clamping support rod 544 is slidably connected inside the cylindrical grooves 542. A clamping plate 545 is fixedly connected to one end of the clamping support rod 544. Tooth marks 548 are formed on the outer side of the clamping plate 545. A connecting plate 547 is fixedly connected to the outer side of the clamping plate 545 near the clamping housing 541. A housing groove 546 is formed inside the clamping housing 541. The connecting plate 547 is slidably connected to the inner side of the housing groove 546. During the movement of the component driven by the sliding block 53, the clamping plate 545 comes into contact with the workpiece. The clamping plate 545 drives the clamping support rod 544 to compress and contract the first spring 543, thereby playing a role in shock absorption and buffering, reducing the clamping pressure of the component, avoiding rigid collisions between components, and maintaining the stability of the workpiece. At the same time, the first spring 543 absorbs the amplitude of the milling process, further maintaining the stability of the workpiece. By opening the toothed marks 548 on the plate surface, the chips are guided, reducing chip residue and preventing chips from affecting the clamping effect of the component during the clamping process, thus avoiding scratches on the surface of the workpiece. Secondly, when the clamping plate 545 moves with the clamping support rod 544, the clamping plate 545 drives the connecting plate 547 to slide inward into the housing groove 546, thereby further improving the stability of the component during movement.

[0053] The conveying mechanism 4 includes a conveying frame 41, with second electric push rods 42 fixedly connected to both sides of the conveying frame 41. A positioning device 43 is fixedly connected to the external output end of the second electric push rods 42. After the workpiece is horizontally aligned with the positioning device 43, the second electric push rods 42 clamp and squeeze both ends of the workpiece to fix it in place. Then, the conveying frame 41 slides on the second guide rod 9 to achieve automatic loading and unloading. The conveying mechanism 4 and the clamping device 5 perform clamping and adaptation operations.

[0054] The positioning device 43 includes a positioning frame 431, with a frame groove 432 inside the positioning frame 431. A second spring 433 is installed inside the frame groove 432. A spherical block 434 is fixedly connected to one side of the second spring 433. A limiting plate 435 is fixedly connected inside the frame groove 432 near the spherical block 434. An annular frame 438 is pluggable and adaptable to the outside of the positioning frame 431. A frame slot 439 is opened on the inner side of the annular frame 438, and the frame slot 439 is pluggable and adaptable to the spherical block 434. When the annular frame 438 moves to the positioning frame 431 for docking, the slot 439 of the frame engages with the spherical block 434. During the docking process, the spherical block 434 is compressed and contracted by the second spring 433, thereby providing space for the component to move. At the same time, the second spring 433 supports the spherical block 434, thereby quickly fixing the component. The limiting plate 435 constrains the spherical block 434, restricting its movement space, preventing the spherical block 434 from derailing, and maintaining the normal operation of the equipment.

[0055] A positioning housing 436 is fixedly connected to the outer side of the ring-shaped frame 438 away from the second electric push rod 42. A plastic film 437 is fixedly connected to the working surface of the positioning housing 436. The positioning housing 436 presses and fixes the two ends of the workpiece. The plastic film 437 increases the wear resistance of the positioning housing 436, reduces wear between parts, and extends the service life of the parts. Secondly, the plastic material increases the anti-slip effect of the parts and improves the stability of the workpiece fixation.

[0056] In use, the conveying mechanism 4 slides on the second guide rod 9 to automatically feed materials up and down. The conveying mechanism 4 is equipped with a second electric push rod 42. The second electric push rod 42 applies pressure to both ends of the workpiece to fix the workpiece. Then, the conveying mechanism 4 moves the workpiece to the milling device 2 to facilitate subsequent milling operations.

[0057] When the conveying mechanism 4 moves the workpiece to the designated position, the clamping device 5 squeezes and clamps the workpiece from both sides to fix the workpiece. The conveying mechanism 4 and the clamping device 5 are matched to improve the clamping effect on the workpiece and strengthen the stability of the workpiece clamping.

[0058] The milling device 2 controls the milling cutter 204 to move onto the workpiece via the first electric push rod 202, thereby achieving the milling operation;

[0059] Considering that there is a tool-walking operation in the milling operation, the clamping device 5 and the conveying mechanism 4 work together to move the workpiece and adapt it to the milling device 2, thereby realizing the walking milling operation;

[0060] During the milling process, the shielding housing 207 and the outer housing 208 shield the chips to prevent them from splashing, thus preventing the chips from affecting the operation of the equipment, reducing the wear of parts caused by chips, and extending the service life of the equipment.

[0061] The fallen debris is collected by the discharge mechanism 3, which guides and collects the debris for subsequent unified processing.

[0062] Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
