Description

Technical Field

[0001] This invention relates to the technical field of grinding equipment for self-priming water pumps, and specifically to a dust-collecting grinding equipment for processing self-priming water pumps. Background Technology

[0002] In the process of water pump production, water pump workpieces often need to be ground. Grinding equipment such as grinding wheels are often used in the grinding process, and the grinding wheels on the equipment are used for processing. Chinese Patent Publication No. CN110216549B, entitled "A Rapid Adjustable Grinding Machine for Processing Water Pump Workpieces," comprises: a machine body, a rack, and a grinding wheel spindle; a set of large slide plates are slidably connected to the top surface of the machine body; a set of left-right adjustment handwheels are axially connected to the lower part of the front end face of the large slide plates; a set of front-rear adjustment handwheels are axially connected to the upper part of the front end face of the large slide plates; a set of rotary handwheels are axially connected to the left end face of the small slide plate; and a set of left-right shift handwheels are threadedly connected to the right end face of the large slide plate. The shortcomings of the above-mentioned existing technical solutions are as follows: after the workpiece is clamped, the grinding device needs to be quickly and initially positioned for the processing position, so the grinding device needs to be adjusted. Although the above solutions can make the grinding equipment perform various movements, each direction of movement can only be operated individually and cannot be performed simultaneously, resulting in low operating efficiency. At the same time, the dust generated during the grinding process is not effectively treated, resulting in a harsh working environment and affecting the work effect. Summary of the Invention

[0003] In order to overcome the above-mentioned technical problems, the purpose of this invention is to provide a dust-collecting grinding device for processing self-priming water pumps.

[0004] The objective of this invention can be achieved through the following technical solutions: A dust-collecting grinding device for processing self-priming water pumps includes a main guide rail and a secondary guide rail. The secondary guide rail is slidably mounted on the main guide rail, and a slide block is slidably connected to the secondary guide rail. A grinding device is mounted on the slide block. A dust-collecting mechanism is mounted on the grinding device. A clamping support is connected to one side of the main guide rail. A drive motor is connected to the bottom of one end of the secondary guide rail. A main drive wheel is connected to the main shaft end of the drive motor. A first docking linkage mechanism that cooperates with the main drive wheel is provided on the main guide rail. A steering drive wheel is rotatably connected to the secondary guide rail. A first steering helical gear is also coaxially connected to the main shaft end of the drive motor. A second steering helical gear that meshes with the first steering helical gear is coaxially connected to the steering drive wheel. A second docking linkage mechanism that cooperates with the slide is provided on both the upper and lower sides of the steering drive wheel.

[0005] As a further aspect of the present invention: both the first docking linkage mechanism and the second docking linkage mechanism include a strip-shaped horizontal plate and a telescopic connecting rod. The strip-shaped horizontal plate of the second docking linkage mechanism cooperates with the steering drive wheel. The strip-shaped horizontal plate of the first docking linkage mechanism is horizontally arranged at the bottom of the main drive wheel. The telescopic connecting rod is connected to the corresponding strip-shaped horizontal plate. One end of the telescopic connecting rod on the second docking linkage mechanism is connected to the slide block, and one end of the telescopic connecting rod on the first docking linkage mechanism is connected to the outer wall of the main guide rail. The strip-shaped horizontal plate is equipped with a locking mechanism. A reset mechanism is also provided on the strip-shaped horizontal plate.

[0006] As a further aspect of the present invention: the locking mechanism includes a stop bolt, the stop bolt is disposed on one side of the strip-shaped horizontal plate, the end of the telescopic connecting rod away from the strip-shaped horizontal plate is connected to a first connecting sleeve, a slide rod is slidably inserted on the first connecting sleeve, the end of the slide rod is connected to a connecting protrusion, and the stop bolt slidably passes through the connecting protrusion.

[0007] As a further aspect of the present invention: the reset mechanism includes a lifting plate, which is arranged parallel to the strip horizontal plate. The end of the telescopic connecting rod away from the strip horizontal plate is connected to a second connecting sleeve. A lifting column is slidably inserted through the second connecting sleeve. One end of the lifting column is connected to the lifting plate, and the other end is movably connected to a linkage rod through a hinge. The end of the linkage rod is connected to a corresponding sliding rod through a hinge. Multiple through holes are equidistantly opened laterally on the strip horizontal plate, and top rods are provided in the through holes.

[0008] As a further aspect of the present invention: the dust collection mechanism includes a dust collection pump, which is disposed above the grinding device, and the dust collection end of the dust collection pump is provided with a conduit; the bottom of the conduit is rotatably provided with a flared sleeve, a drive motor is disposed inside the conduit, and the main shaft end of the drive motor is connected to the flared sleeve, and a dust removal curtain is disposed at the bottom of the flared sleeve.

[0009] As a further aspect of the present invention: the dust removal curtain includes an inner film and an outer film. The inner film is disposed at the bottom inner ring of the flared sleeve, and the outer film is disposed at the bottom outer ring of the flared sleeve. Multiple inner and outer films are provided and distributed circumferentially. Both the inner and outer films are provided with capture grooves.

[0010] As a further aspect of the present invention: the two ends of the inner film are respectively overlapped with the ends of the outer film at adjacent positions.

[0011] As a further aspect of the present invention: an elastic rubber sleeve is fitted onto the flared sleeve, and the upper ends of both the inner and outer rubber sheets are connected to the elastic rubber sleeve.

[0012] The beneficial effects of this invention are: 1. The grinding device of the present invention can be moved and adjusted along the main guide rail and the secondary guide rail. When the grinding device needs to move in both the main guide rail and the secondary guide rail directions at the same time, it is only necessary to make the strip plate in the first docking linkage mechanism dock with the main drive wheel, and the strip plate in the corresponding second docking linkage mechanism dock with the steering drive wheel. Then, the drive motor is started, which can make the grinding device slide along the secondary guide rail, and the secondary guide rail can also make the grinding device slide along the main guide rail, so that multiple movements can be performed at the same time. 2. After the strip plate of the present invention is connected with the main drive wheel or the steering drive wheel, the set top rod can be inserted into the corresponding hole on the strip plate. Once there is relative movement between the drive wheel and the corresponding strip plate, and the drive wheel eventually rolls onto the top rod so that it completely passes through the hole, the top rod pushes against the lifting plate. The lifting plate moves away from the strip plate by means of the linkage stop bolt, which facilitates the separation of the strip plate from the corresponding drive wheel. In this way, the drive wheel can be prevented from transmitting to the grinding device and stop at the corresponding position. 3. When the grinding device of the present invention performs grinding, it relies on a dust pump to suck up dust. During the dust suction process, the drive motor drives the flared sleeve of the dust suction end to rotate, and the dust removal curtain on the flared sleeve unfolds outward under the action of centrifugal force. The speed of the drive motor can be adjusted according to the dust diffusion range during the grinding process, so that the dust removal curtain opens at different angles under different centrifugal forces, so as to block the dust that has not been sucked up and has been scattered. The dust is captured by the opening capture groove, thereby enhancing the dust removal effect. Attached Figure Description

[0016] 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.

[0017] like Figures 1-6 As shown, a dust-collecting grinding device for processing a self-priming water pump includes a main guide rail 1 and a secondary guide rail 2. The secondary guide rail 2 is slidably disposed on the main guide rail 1 and is perpendicular to the main guide rail 1. A slide block 15 is slidably connected to the secondary guide rail 2. A grinding device is mounted on the slide block 15. The grinding device includes a grinding drive assembly 13, which is mounted on the slide block 15. A grinding wheel 14 is provided at the output end of the grinding drive assembly 13. The grinding device can slide left and right along the secondary guide rail 2 by relying on the slide block 15, and can also slide forward and backward along the main guide rail 1 by relying on the secondary guide rail 2. The grinding device is equipped with a dust collection mechanism, which includes a dust pump 8. The dust pump 8 is positioned above the grinding device, and its suction end is equipped with a conduit 42. An electric guide rail 9 is fixedly connected to the grinding drive assembly 13. The conduit 42 is slidably connected to the electric guide rail 9, which allows the dust pump 8 to move up and down to adjust its height for dust collection. A flared sleeve 18 is rotatably mounted at the bottom of the conduit 42. A drive motor 17 is installed inside the conduit 42, and the spindle end of the drive motor 17 is connected to the flared sleeve 18 via a bracket. The drive motor 17 drives the flared sleeve 18 to rotate. A dust removal curtain 20 is provided at the bottom of the flared sleeve 18. The dust removal curtain 20 includes an inner film 40 and an outer film 39. The inner film 40 is located at the inner bottom ring of the flared sleeve 18, and the outer film 39 is located at the outer bottom ring of the flared sleeve 18. Both the inner film 40 and the outer film 39 are provided with multiple... There are several dust collector curtains 20, which are distributed circumferentially. The two ends of the inner film 40 overlap with the ends of the outer film 39 at the adjacent positions. Both the inner film 40 and the outer film 39 are provided with capture grooves, and the capture grooves are filled with glue. During the grinding process, the dust pump 8 is turned on to perform dust collection, and at the same time, the drive motor 17 is turned on to drive the flared sleeve 18 to rotate. As a result, the dust collector curtains 20 distributed at the bottom rotate accordingly and open outward under the action of centrifugal force, which can increase the shielding range and facilitate the shielding of scattered dust and guide the dust into the duct 42. The speed of the drive motor 17 is controlled according to the dust generation. If the dust diffusion range is large, the speed of the drive motor 17 is increased, which increases the centrifugal force on the dust collector curtain 20 and thus increases the opening angle. The inner film 40 and the outer film 39 of the dust collector curtain 20 are both provided with capture grooves filled with glue, which can facilitate the entry and adhesion of dust to achieve capture. An elastic rubber sleeve 19 is fitted onto the flared sleeve 18. The upper ends of the inner rubber sheet 40 and the outer rubber sheet 39 are both connected to the elastic rubber sleeve 19. When the dust removal curtain 20 needs to be replaced, the elastic rubber sleeve 19 can be removed from the flared sleeve 18. A clamping support is fixedly connected to one side of the main guide rail 1. The clamping support includes a support base 4, which is fixedly connected to the main guide rail 1. A turntable 5 is rotatably connected to the support base 4, and a hydraulic telescopic rod 6 is fixedly connected to the turntable 5. A pump body clamp 7 is installed at the telescopic end of the hydraulic telescopic rod 6. The pump body clamp 7 is used to fix and clamp the pump body parts to be ground. An adjusting motor 3 is fixedly connected to the bottom of the support base 4, and the spindle end of the adjusting motor 3 is connected to the rotating end of the turntable 5. When the pump body parts to be ground are clamped on the pump body clamp 7, the height of the workpiece can be adjusted by telescopically extending and retracting the hydraulic telescopic rod 6. The turntable 5 can also be rotated by adjusting the motor 3, thereby rotating the workpiece and adjusting its angular position relative to the grinding wheel 14. A drive motor 16 is fixedly connected to the bottom of one end of the auxiliary guide rail 2. The drive motor 16 is equipped with a speed controller for speed control. A main drive wheel 21 is connected to the main shaft of the drive motor 16. A first docking linkage mechanism 41 that cooperates with the main drive wheel 21 is provided on the main guide rail 1. A steering drive wheel 31 is rotatably connected to the auxiliary guide rail 2 via a bracket. A first steering helical gear 33 is also coaxially connected to the main shaft of the drive motor 16. A second steering helical gear 32 that meshes with the first steering helical gear 33 is coaxially connected to the steering drive wheel 31. A second docking linkage mechanism 43 that cooperates with the slide block 15 is provided on both the upper and lower sides of the steering drive wheel 31. Both the first docking linkage mechanism 41 and the second docking linkage mechanism 43 include a strip-shaped horizontal plate 27 and a telescopic connecting rod 29. The strip-shaped horizontal plate 27 of the second docking linkage mechanism 43 is connected to the steering drive wheel 31. In coordination, the strip plates 27 of the two sets of second docking linkage mechanisms 43 are respectively located on the upper and lower sides of the steering drive wheel 31, and the strip plates 27 of the first docking linkage mechanism 41 are horizontally set at the bottom of the main drive wheel 21. The specific length of the strip plates 27 can be set according to the length of the main guide rail 1 or the secondary guide rail 2. The strip plates 27 are distributed with anti-slip textures. The telescopic connecting rods 29 are vertically connected to the corresponding strip plates 27. One end of the telescopic connecting rods 29 on the second docking linkage mechanism 43 is connected to the slide block 15, and one end of the telescopic connecting rods 29 on the first docking linkage mechanism 41 is connected to the outer wall of the main guide rail 1. The end of the telescopic connecting rod 29 away from the strip plate 27 is connected to the strip plate 27 with a first spring 30. The strip plates 27 are equipped with a locking mechanism; the strip plates 27 are also equipped with a reset mechanism that cooperates with the locking mechanism. The locking mechanism includes a stop bolt 23, which is located on one side of the strip horizontal plate 27. The end of the telescopic connecting rod 29 away from the strip horizontal plate 27 is fixedly connected to a first connecting sleeve 25. A slide rod 24 is slidably inserted on the first connecting sleeve 25. A connecting protrusion 22 is vertically fixedly connected to the end of the slide rod 24. The stop bolt 23 slides through the connecting protrusion 22. The reset mechanism includes a lifting plate 38, which is parallel to the strip horizontal plate 27. A second connecting sleeve 34 is fixedly connected to one end of the telescopic connecting rod 29 away from the strip horizontal plate 27. A lifting column 37 is slidably inserted through the second connecting sleeve 34. A second spring 36 is connected between the second connecting sleeve 34 and the lifting column 37. One end of the lifting column 37 is connected to the lifting plate 38, and the other end is movably connected to a linkage rod 35 through a hinge. The end of the linkage rod 35 is connected to the corresponding slide rod 24 through a hinge. Multiple through holes 28 are equidistantly opened on the strip horizontal plate 27. Anti-slip washers are provided in the through holes 28. A top rod 26 is provided in the through holes 28. The anti-slip washers ensure that the top rod 26 is stable after insertion and will not fall off under the action of gravity. When the grinding device needs to slide left or right along the secondary guide rail 2 using the slide block 15, the strip plate 27 in the second docking linkage mechanism 43 on the upper or lower side of the steering drive wheel 31 is brought into contact with the steering drive wheel 31 by the extension movement of the telescopic connecting rod 29. During this process, the first spring 30 is stretched to generate a rebound force, and then the corresponding stop 23 is slid to block the end of the strip plate 27, preventing the strip plate 27 from returning to its original position by the rebound force of the first spring 30. According to the distance the grinding device needs to slide, the top rod 26 is inserted into the corresponding hole 28 in the forward direction of the steering drive wheel 31, with one end exposed. Then the drive motor 16 is started. The drive motor 16 drives the first steering helical gear 33 to rotate, which in turn drives the meshing second steering helical gear 32 to rotate. This causes the steering drive wheel 31 to rotate. During this rotation, the mating strip plate 27 is subjected to force and moves laterally, thereby causing the slide block 15 to move laterally along the secondary guide rail 2. When the push rod 26 placed on the strip plate 27 enters the area of ​​the steering drive wheel 31, the push rod 26 is rolled by the steering drive wheel 31. Then, the push rod 26 completely penetrates the through hole 28 and pushes against the lifting plate 38. The lifting plate 38 then drives the lifting column 37 to move away from the strip plate 27. During this process, the end of the lifting column 37... The linkage 35 drives the slide bar 24 to slide laterally, which in turn causes the stop bolt 23 on the connecting protrusion 22 to move laterally as well. The stop bolt 23 then disengages from the strip plate 27, and the strip plate 27 is reset by the return force of the first spring 30, separating from the steering drive wheel 31. This allows the grinding device to stop in time after the slide block 15 drives the grinding device to the corresponding position along the secondary guide rail 2. When the grinding device needs to slide along the main guide rail 1, the strip plate 27 in the first docking linkage mechanism 41 on the lower side of the main drive wheel 21 is attached to the main drive wheel 21, and cooperates with the second docking linkage mechanism 43 and the steering drive wheel 31 as described above. This enables grinding. The device slides along the main guide rail 1 and stops at a fixed point. When the grinding device needs to move in both the main guide rail 1 and the secondary guide rail 2 at the same time, it is only necessary to make the strip plate 27 in the first docking linkage mechanism 41 dock with the main drive wheel 21, and the strip plate 27 in the corresponding second docking linkage mechanism 43 dock with the steering drive wheel 31. The top rod 26 on each strip plate 27 is inserted into the corresponding through hole 28. Then the drive motor 16 is started, and multiple movements can be performed simultaneously. The forward or reverse movement of the grinding device on the secondary guide rail 2 depends on the spindle rotation of the drive motor 16 and the position of the selected second docking linkage mechanism 43. Electric telescopic rods 12 are fixedly connected to both the grinding device and the secondary guide rail 2. Anti-slip blocks 11 are fixedly connected to the telescopic ends of the electric telescopic rods 12. Fixed plates 10 that are aligned with the corresponding anti-slip blocks 11 are connected to both the main guide rail 1 and the secondary guide rail 2. When it is necessary to keep the grinding device fixed relative to the main guide rail 1 and the secondary guide rail 2 after the position is adjusted, the electric telescopic rods 12 are activated so that the anti-slip blocks 11 at their telescopic ends abut against the fixed plates 10.

[0018] The working principle of this invention is as follows: The pump body and the parts to be ground are clamped on the pump body fixture 7; at the same time, when adjusting the initial position of the equipment, the distance that the grinding wheel 14 needs to move in the direction of the main guide rail 1 and the direction of the secondary guide rail 2 can be initially determined. Then, the strip plate 27 in the first docking linkage mechanism 41 is made to fit and dock with the main drive wheel 21, and the strip plate 27 in the corresponding position of the second docking linkage mechanism 43 is made to fit and dock with the steering drive wheel 31. At the same time, the corresponding stop bolt 23 is slid to block the end of the strip plate 27, so as to prevent the strip plate 27 from returning to its original position by the rebound force of the first spring 30. According to the distance that the grinding device needs to slide, the top rod 26 on each strip plate 27 is inserted into the corresponding through hole 28. Then, the drive motor 16 is started. The drive motor 16 directly drives the main drive wheel 21 to rotate, and simultaneously drives the first steering helical gear 33 to rotate. The first steering helical gear 33 then drives the meshing second steering helical gear 32 to rotate, thus causing the steering drive wheel 31 to rotate. During the rotation of the steering drive wheel 31, the corresponding mating strip plate 27 is subjected to force and moves laterally, thereby causing the slide block 15 to move laterally along the secondary guide rail 2. Meanwhile, the main drive wheel 21 rolls along the corresponding strip plate 27, causing the secondary guide rail 2 to slide along the main guide rail 1, achieving simultaneous operation of multiple movements. When the main drive wheel 21 or the steering drive wheel 31 contacts the corresponding push rod 26, the push rod 26 is subjected to force. The roller is rolled through the perforation 28 and the top rod 26 pushes against the lifting plate 38. The lifting plate 38 then moves the lifting column 37 away from the strip plate 27. During this process, the linkage rod 35 at the end of the lifting column 37 moves the slide rod 24 laterally. In this way, the slide rod 24 moves the stop bolt 23 on the connecting protrusion 22 laterally. The stop bolt 23 disengages from the strip plate 27. Then the strip plate 27 is reset under the action of the rebound force of the first spring 30 and separates from the steering drive wheel 31 or the main drive wheel 21. In this way, the grinding device can slide along the secondary guide rail 2 or the main guide rail 1 to the corresponding position and stop in time. When it is necessary to adjust the movement of the grinding device in a certain direction, the first docking linkage mechanism 41 or the second docking linkage mechanism 43 can be activated independently; at the same time, the height of the workpiece can be adjusted by extending and retracting the hydraulic telescopic rod 6, and the turntable 5 can be rotated by adjusting the motor 3, thereby rotating the workpiece and adjusting the angular position relative to the grinding wheel 14. During the grinding process, the dust pump 8 is turned on to perform dust removal, and the drive motor 17 is turned on to drive the flared sleeve 18 to rotate. As a result, the dust removal curtains 20 distributed at the bottom rotate accordingly and open outward under the action of centrifugal force, which can increase the shielding range and facilitate the blocking of scattered dust and guide the dust into the duct 42. The speed of the drive motor 17 is controlled according to the dust generation. If the dust spreads over a large area, the speed of the drive motor 17 is increased, which increases the centrifugal force on the dust removal curtains 20 and thus increases the opening angle. The inner film 40 and the outer film 39 of the dust removal curtains 20 are both distributed with adhesive trapping grooves, which facilitate the entry and adhesion of dust, thus achieving capture.

[0019] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
