[0018] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0019] The embodiment of the present invention provides a surface burr removal device for impeller machining, such as Figure 1-10 As shown, the surface burr removal equipment for impeller processing includes: a workbench 1 and a grinding disc 2 arranged above the workbench 1 for removing burrs on the impeller surface; a hole plate 3 assembled in the mounting opening of the workbench 1; a suction hopper 4 fixedly mounted at the bottom of the workbench 1 for dust collection, and a fan blade 5 arranged in the suction hopper 4; a dust removal box 6 installed at the bottom of the workbench 1 for collecting and filtering dust; and a fixing mechanism arranged on the workbench 1 for fixing the impeller.

[0020] In this embodiment, first, the impeller to be processed is placed on the hole plate 3 and secured by a fixing mechanism. Subsequently, the grinding disc 2 is started to grind the surface of the impeller. During the grinding process, the fan blades 5 in the suction hopper 4 start to rotate at high speed, generating a strong suction force. This suction force sucks the dust generated by grinding into the suction hopper 4 and transports it to the dust removal box 6 through the connecting pipe 22. The dust removal box 6 is responsible for collecting and filtering the dust to ensure the air quality in the working environment. Through the combination of the suction hopper 4 and the fan blades 5, as well as the collection and filtering function of the dust removal box 6, the equipment can efficiently remove the dust generated during the grinding process and significantly reduce the dust concentration in the air. The efficient dust removal mechanism effectively reduces the risk of workers inhaling dust, thereby protecting the workers' respiratory system and overall health. The clean working environment helps workers stay focused and reduces operational errors caused by dust interference, thereby improving overall work efficiency.

[0021] In a further preferred embodiment of the present invention, a hydraulic cylinder 7 is fixedly installed on the top of the workbench 1, a support frame 8 is fixedly installed on the output rod of the hydraulic cylinder 7, a mounting plate 9 is installed on the support frame 8, the mounting plate 9 is rotatably connected to the grinding disc 2, a first motor 10 is fixedly installed on the mounting plate 9, and the output shaft of the first motor 10 is connected to the rotating shaft of the grinding disc 2.

[0022] In this embodiment, after the impeller is placed on the hole plate 3, the hydraulic cylinder 7 adjusts the grinding disc 2 to an appropriate height. At the same time, the impeller is fixed by a fixing mechanism, and the first motor 10 starts to drive the grinding disc 2 to rotate for grinding operation. At the same time, the fan blades 5 in the suction bucket 4 rotate at high speed to generate suction, sucking in the dust generated by grinding and collecting and filtering it through the dust removal box 6. By adding the hydraulic cylinder 7, the height of the grinding disc 2 can be precisely adjusted to adapt to impellers of different sizes and shapes, thereby improving the versatility and flexibility of the equipment. The grinding disc 2 is directly driven to rotate by the first motor 10, providing stable power output and ensuring the efficient progress of the grinding operation.

[0023] In a further preferred embodiment of the present invention, a rubber telescopic cylinder 11 for preventing dust from spreading is fixedly installed on the bottom of the mounting plate 9, and the rubber telescopic cylinder 11 is covered on the grinding disc 2. A ventilation hole 12 is opened on the top of the mounting plate 9, and a counterweight block 13 is fixedly installed on one side of the support frame 8.

[0024] In this embodiment, when the hydraulic cylinder 7 adjusts the grinding disc 2 to an appropriate height, the rubber telescopic tube 11 will shrink as the grinding disc 2 descends, and tightly cover the impeller and the clamping block 30. Then, the first motor 10 starts to drive the grinding disc 2 to rotate for grinding operation. At the same time, the fan blades 5 in the suction bucket 4 rotate at high speed to generate suction, and the dust in the rubber telescopic tube 11 is sucked in through the vent 12 and collected and filtered through the dust removal box 6, while the counterweight 13 ensures the balance and stability of the support frame 8. The addition of the rubber telescopic tube 11 effectively isolates the dust generated during the grinding process, avoids the spread of dust, and further protects the health of the workers. The setting of the vent 12 enables the dust collection system to work more efficiently, improves the dust collection efficiency, and ensures the balance and stability of the support frame 8 by adding the counterweight 13, prevents the hydraulic cylinder 7 from generating torque during the lifting process, and extends the service life of the equipment.

[0025] In a further preferred embodiment of the present invention, the suction bucket 4 is provided with a driving mechanism for driving the fan blade 5 to rotate, and the driving mechanism includes: a bracket 14 fixedly installed in the suction bucket 4, the bracket 14 is rotatably connected to the rotating shaft of the fan blade 5; a protective cover 15 installed at the bottom of the bracket 14; a connecting rod 16 rotatably installed on one side of the suction bucket 4, one end of the connecting rod 16 extends into the protective cover 15; a first bevel gear 17 fixedly sleeved on the connecting rod 16 and the rotating shaft of the fan blade 5, respectively, and the two first bevel gears 17 are meshed with each other; a rotating rod 18 rotatably installed on the suction bucket 4 and the dust removal box 6; a differential gear 19 provided on the rotating rod 18 and one side of the suction bucket 4, respectively, and the two differential gears 19 are meshed with each other; a second motor 22 installed on the suction bucket 4, and a connecting sprocket 20 is fixedly sleeved on the output shaft of the second motor 22 and the rotating rod 18, and a first chain 21 is sleeved on the two connecting sprockets 20.

[0026] In this embodiment, when it is necessary to drive the fan blades 5 to rotate, the second motor 22 is started, and its output shaft drives the connecting sprocket 20 to rotate. Through the transmission of the first chain 21, the rotating rod 18 realizes synchronous rotation. Subsequently, the rotating rod 18 transmits the rotational force to the differential gear 19. Due to the size design difference of the differential gear 19, the rotation speed of the connecting rod 16 is higher than that of the rotating rod 18. Finally, the connecting rod 16 transmits the rotational force to the rotating shaft of the fan blade 5 through the first bevel gear 17, realizing high-speed rotation of the fan blade 5. Through the combined design of chain drive and differential drive, high-speed rotation of the fan blade 5 is realized, and the dust collection efficiency is improved. All driving components are compactly installed in the suction bucket 4, which reduces the footprint and improves the overall aesthetics and practicality of the equipment. The setting of the protective cover 15 effectively protects the rotating shaft of the fan blade 5 and its driving components, prevents the invasion of dust and other debris, and extends the service life of the equipment.

[0027] In a further preferred embodiment of the present invention, a connecting pipe 23 is fixedly installed on one side of the dust removal box 6, and the connecting pipe 23 is connected to the suction hopper 4. A protective cover 50 is provided on the suction hopper 4, and the protective cover 50 is provided on the second motor 22 and the differential gear 19 to protect the differential gear 19 and the connecting sprocket 20.

[0028] In this embodiment, a protective cover 50 is provided on the suction hopper 4, and the protective cover 50 effectively covers the second motor 22 and the differential gear 19. This design not only protects the second motor 22 from the invasion of dust and other debris, thereby extending its service life, but also plays a good protective role for transmission components such as the differential gear 19 and the connecting sprocket 20, thereby preventing transmission failures caused by the invasion of foreign matter. The setting of the connecting pipe 23 ensures the smoothness of the dust collection channel, improves the dust collection efficiency, and enables the dust generated during the grinding process to be collected and processed in a timely and effective manner.

[0029] In a further preferred embodiment of the present invention, a plurality of filters 24 for filtering dust are slidingly provided in the dust removal box 6, a water tank 26 for absorbing dust is provided at the bottom of the dust removal box 6, a plurality of connection ports 25 are opened at the bottom of the dust removal box 6, and the plurality of connection ports 25 are all connected to the water tank 26, and a partition 27 is fixedly installed at the bottom of the dust removal box 6, and the partition 27 will be used to separate the plurality of connection ports 25.

[0030] The dust collected by the filter 24 is then sucked into the dust collecting box 6 and the dust is then collected by the dust collecting box 6.

[0031] In a further preferred embodiment of the present invention, the fixing mechanism includes: a bidirectional screw 28 rotatably mounted on the top of the workbench 1; a group of sliders 29 all threadedly sleeved on the bidirectional screw 28; a group of clamping blocks 30 respectively provided on a group of the sliders 29 for clamping and fixing the impeller; anti-slip pads 31 respectively installed on the group of the clamping blocks 30; and a rotating mechanism provided on the mounting plate 9 and the bidirectional screw 28 for driving the bidirectional screw 28 to rotate.

[0032] In this embodiment, when the impeller needs to be clamped and fixed, the hydraulic cylinder 7 drives the mounting plate 9 to slide down, thereby starting the rotating mechanism and driving the bidirectional screw 28 to rotate. Since the slider 29 is threadedly sleeved on the bidirectional screw 28, when the bidirectional screw 28 rotates, a group of sliders 29 will slide close to each other, thereby driving the clamping block 30 and the anti-slip pad 31 to approach the impeller. When the clamping block 30 and the anti-slip pad 31 are tightly fitted on the impeller, the impeller is clamped and fixed. When it is necessary to release the impeller or adjust the clamping position, the mounting plate 9 slides up, and the rotating mechanism drives the bidirectional screw 28 in the reverse direction to rotate, causing a group of sliders 29 to slide away from each other, thereby driving the clamping block 30 and the anti-slip pad 31 to move away from the impeller, thereby realizing the release of the impeller or the adjustment of the clamping position. Through the threaded cooperation of the bidirectional screw 28 and the slider 29, the impeller is clamped and fixed quickly and stably, thereby improving work efficiency. The anti-slip pad 31 on the clamping block 30 increases the clamping force and prevents the impeller from sliding during the grinding process, thereby ensuring the accuracy and safety of the grinding. Through the drive of the rotating mechanism, the position and clamping force of the clamping block 30 can be easily adjusted to adapt to impellers of different sizes and shapes.

[0033] In a further preferred embodiment of the present invention, a mounting seat 32 is fixedly mounted on one side of the slider 29 , and the mounting seat 32 is connected to the clamping block 30 via bolts.

[0034] In this embodiment, the mounting base 32 and the clamping block 30 are connected by bolts, so that the clamping block 30 can be easily disassembled and replaced when it is damaged or needs to be replaced, thereby reducing maintenance costs and time. Through the fixation of the mounting base 32, the installation of the clamping block 30 is more stable and not easy to loosen, thereby improving the stability and safety of the clamping. At the same time, this design allows the clamping block 30 to be selected from different materials, shapes and sizes as needed to adapt to impellers of different sizes and shapes, thereby improving the adaptability and flexibility of the equipment.

[0035] In a further preferred embodiment of the present invention, the rotating mechanism includes: a driven gear 33 fixedly mounted on the bidirectional screw 28; a rack 34 fixedly mounted on the bottom of the mounting plate 9, the rack 34 being engaged with the driven gear 33; a sliding opening 35 opened on the workbench 1 for sliding of the rack 34; and a guide plate 36 fixedly mounted in the sliding opening 35 for guiding the rack 34.

[0036] In this embodiment, when the hydraulic cylinder 7 is started and pushes the grinding disc 2 to descend, the mounting plate 9 will also descend synchronously. Since the rack 34 is fixedly mounted on the bottom of the mounting plate 9, the rack 34 will also descend along with the mounting plate 9. During the descent of the rack 34, it will mesh with the driven gear 33 and drive the driven gear 33 to rotate. The rotation of the driven gear 33 will drive the bidirectional screw 28 to rotate. Since the slider 29 is threadedly sleeved on the bidirectional screw 28, the sliders 29 will slide close to each other, thereby driving the clamping block 30 to approach the blade together. Wheel, when the clamping block 30 fits tightly on the impeller, the impeller is clamped and fixed. Through the rotating mechanism, the synchronous operation of the grinding disc 2 descending and the impeller clamping is realized, which simplifies the operation process and improves work efficiency. The setting of the guide plate 36 ensures the stability of the rack 34 during the sliding process, avoids unstable clamping or equipment damage caused by shaking, and the sliding mouth 35 is opened on the workbench 1 for the sliding of the rack 34. The guide plate 36 is fixedly installed in the sliding mouth 35 to guide the rack 34 to ensure its stable sliding.

[0037] In a further preferred embodiment of the present invention, a support rod 37 is fixedly installed on the bottom of the dust removal box 6, a connecting frame 38 is fixedly installed on one side of the water tank 26, and a screw rod 39 is threadedly installed on one side of the connecting frame 38, and the screw rod 39 is in close contact with the support rod 37.

[0038] The screw rod 39 is then rotated to make it gradually approach and closely contact the support rod 37. Since the screw rod 39 is threadedly connected to the connecting frame 38, the tightness between the screw rod 39 and the support rod 37 can be adjusted by rotating the screw rod 39, thereby achieving the fixation of the water tank 26. By designing the connecting frame 38 and the screw rod 39, the installation process of the water tank 26 is more convenient, without the need for complicated fixing devices or tools, and the installation difficulty and time are reduced. The design of the close contact between the screw rod 39 and the support rod 37 ensures the stability of the water tank 26 at the bottom of the dust removal box 6, avoiding equipment damage or safety hazards caused by shaking. By designing the connecting frame 38 and the screw rod 39, the water tank 26 can be easily disassembled and replaced, and it is also convenient for cleaning and maintenance of the dust removal box 6 and the water tank 26. In order to further improve the use effect of this device, in addition to the above scheme, this scheme also has the following embodiments: In another embodiment of the present invention, a sealing strip 40 is installed in the groove at the bottom of the dust removal box 6 , and the bottom of the sealing strip 40 is in close contact with the top of the water tank 26 .

[0039] In this embodiment, when the water tank 26 is installed at the bottom of the dust removal box 6, the top of the water tank 26 will be in close contact with the groove at the bottom of the dust removal box 6. At this time, the sealing strip 40 is located in the middle of the contact surface of the two, playing a filling and sealing role. Since the sealing strip 40 has good elasticity, it can fit tightly to the top of the water tank 26 and the groove of the dust removal box 6, effectively preventing dust and moisture from leaking from the gap in the contact surface.

[0040] In another embodiment of the present invention, a dust cleaning mechanism is provided on the dust removal box 6, and the dust cleaning mechanism includes: a rectangular box 41 fixedly installed in the dust removal box 6; a cleaning brush 42 rotatably installed on one side of the rectangular box 41 for cleaning dust on the filter 24, a fixed rod rotatably installed on one side of the dust removal box 6, one end of the fixed rod extends into the rectangular box 41; a second bevel gear 43 fixedly mounted on the rotating shaft of the cleaning brush 42 and the fixed rod, respectively, and the two bevel gears 43 are meshed with each other; a linkage mechanism is provided on the fixed rod and the rotating rod 18 for synchronously driving the fan blades 5 and the cleaning brush 42 to rotate.

[0041] In this embodiment, when the second motor 22 is started, the linkage mechanism starts working, synchronously driving the fan blades 5 and the fixed rod to rotate. The rotation of the fan blades 5 generates suction, which sucks the dust generated by grinding into the dust removal box 6 and filters it through the filter 24. At the same time, the rotation of the fixed rod is transmitted to the cleaning brush 42 through the engagement of the second bevel gear 43, so that the cleaning brush 42 rotates on the filter 24, and the dust attached to the filter 24 is swept away. The swept dust then falls into the water tank 26. Through the dust cleaning mechanism, the dust on the filter 24 is automatically cleaned without manual intervention, reducing the difficulty and labor intensity of operation. Through the design of the linkage mechanism, the fan blades 5 and the cleaning brush 42 can rotate synchronously, thereby achieving efficient cleaning of the dust. At the same time, the rotation of the cleaning brush 42 can ensure that all parts of the filter 24 can be evenly cleaned, avoiding dust accumulation and blockage, and further improving the overall performance of the equipment and user experience.

[0042] In another embodiment of the present invention, the linkage mechanism includes: a connecting rod 44 rotatably installed on one side of the dust removal box 6; a cross bar 45 provided on one side of the dust removal box 6, and the cross bar 45 is located above the fixed rod; two sets of third bevel gears 46 fixedly mounted on the fixed rod, both ends of the connecting rod 44 and the cross bar 45, and the two sets of third bevel gears 46 are meshed with each other; differential sprockets 47 fixedly mounted on the cross bar 45 and the rotating rod 18, and a second chain 48 is mounted on the two differential sprockets 47; a protective box 49 installed on one side of the dust removal box 6, and the protective box 49 cover is provided on the connecting rod 44 and the two sets of third bevel gears 46, and the protective box 49 is rotatably connected to the cross bar 45.

[0043] In this embodiment, when the second motor 22 is started, it drives the rotating rod 18 to rotate. Since a differential sprocket 47 is fixedly provided on the rotating rod 18, and a second chain 48 is provided on the differential sprocket, the rotation of the rotating rod 18 will drive the synchronous rotation of the second chain 48 and the differential sprocket 47. The rotation of the differential sprocket 47 will drive the rotation of the cross bar 45. Since a differential sprocket 47 is also fixedly provided on the cross bar 45, and the two differential sprockets are connected by the second chain 48, the rotation of the cross bar 45 will be transmitted to the connecting rod 44 and the fixed rod through the engagement of the third bevel gear 46. Since a second bevel gear 43 is fixedly provided on the fixed rod, and the second bevel gear is engaged with the second bevel gear on the rotating shaft of the cleaning brush 42, the rotation of the fixed rod will drive the rotation of the cleaning brush 42.

[0044] By setting the differential sprocket 47, differential rotation between the cross bar 45 and the rotating rod 18 can be achieved. Due to the design of the differential sprocket 47, the rotation speed of the cleaning brush 42 can be much lower than the rotation speed of the fan blade 5. This is because the rotation speed of the fan blade 5 is directly driven by the second motor 22, while the rotation speed of the cleaning brush 42 is obtained through the transmission of a series of gears and sprockets. Therefore, differential rotation can be achieved by adjusting the transmission ratio of the gears and sprockets. By designing a linkage mechanism, the synchronous rotation of the fan blade 5 and the cleaning brush 42 is achieved, and by setting the differential sprocket 47, the rotation speed of the cleaning brush 42 can be adjusted independently of the rotation speed of the fan blade 5, achieving efficient and flexible dust cleaning. The design of the protective box 49 provides effective protection for the linkage mechanism, prevents the invasion of dust and debris, and also ensures the normal operation of the gears and sprockets, thereby extending the service life of the equipment. Through the differential design, the rotation speed of the cleaning brush 42 can be lower than the rotation speed of the fan blade 5, thereby reducing the energy consumption of the equipment and improving energy utilization efficiency.

[0045] In summary, compared with related technologies, this equipment effectively reduces the risk of workers inhaling dust through its efficient dust removal mechanism, providing workers with a healthier and more efficient working environment.
