Description

Technical Field

[0001] The present invention relates to the technical field of polishing devices for metal castings, and specifically to a polishing device for metal castings with a self-cleaning function. Background Technique

[0002] When traditional polishing devices polish metal castings such as flanges, a large amount of debris is usually generated. The continuous accumulation and splashing of the debris may affect the polishing quality. Traditional polishing devices often require workers to manually clean the debris generated during polishing, which is time-consuming and laborious. While increasing the labor intensity of workers, it also reduces the polishing efficiency. Therefore, we need a polishing device for metal castings with a self-cleaning function to solve the above problems. Summary of the Invention

[0003] The purpose of the present invention is to provide a polishing device for metal castings with a self-cleaning function to solve the problems raised in the prior art.

[0004] To achieve the above purpose, the present invention provides the following technical solution:

[0005] The polishing device includes a workbench, a sliding module, a first polishing module, a second polishing module, a gas blowing module, a detection and compensation module, a protective cover, and a workpiece. A chute is provided on the workbench. The protective cover is fixedly connected to the upper end surface of the workbench and is located at one end of the workbench. The sliding module passes through the chute and is fixedly connected to the workbench. One end of the sliding module is inserted into the protective cover. The workpiece is fixedly connected to the sliding module. The first polishing module is fixedly connected to the workbench and is inserted into the protective cover. The second polishing module passes through the workbench and the sliding module in sequence and is inserted into the protective cover. The second polishing module is located between the workpiece in the polishing state and one end of the workbench. The gas blowing module is fixedly connected to the workbench and is connected to the protective cover through a pipeline. The detection and compensation module is fixedly connected to the protective cover and is located inside the protective cover. One end of the first polishing module is rotatably connected to the detection and compensation module.

[0006] The sliding module is responsible for clamping the workpiece and then transporting it to the position to be polished. The first polishing module is responsible for polishing the upper surface of the workpiece. The second polishing module is responsible for polishing the side surface of the workpiece. The air blowing module is responsible for dealing with the debris flying everywhere generated during the polishing of the second polishing module, blocking some of the debris to prevent the debris from hitting the workpiece and thus affecting the polishing quality. At the same time, it blows the other part of the debris that cannot be blocked, so that when the debris hits the side surface of the workpiece, it presents a state tangent to the side surface of the workpiece, reducing the impact force of the debris on the workpiece. Moreover, the air blowing module can also blow the debris to one end of the workbench to achieve the collection and cleaning of the debris. The detection and compensation module is responsible for detecting the vibration generated during the grinding of the first polishing module and making active compensation, reducing the vibration amplitude of the first polishing module, so that the first polishing module does not have a large angular deviation during polishing, ensuring the polishing quality. The protective cover can prevent the debris and dust from flying everywhere.

[0007] Furthermore, a funnel groove is provided at one end of the workbench. The funnel groove is located inside the protective cover and on the side of the second polishing module away from the workpiece.

[0008] The funnel groove can collect the debris generated during polishing. During the operation of the polishing device, the whole device will generate slight vibrations. Under the action of the vibrations, the debris will gather along the inner wall of the funnel-shaped funnel groove towards the central outlet of the funnel groove and be discharged, realizing the self-cleaning of the polishing device.

[0009] Furthermore, the sliding module includes a driving cylinder, a clamping slide, a slide bar, a fixed seat and a guide seat. The guide seat is fixedly connected to one end of the workbench and is located inside the protective cover. The fixed seat is fixedly connected to the other end of the workbench. One end of the slide bar is inserted into the protective cover and fixedly connected to the guide seat. The other end of the slide bar is fixedly connected to the fixed seat. The clamping slide is slidably connected to the slide bar. The clamping slide, the slide bar, the fixed seat and the guide seat are all located above the workbench. The driving cylinder is fixedly connected to the lower end surface of the workbench. The clamping slide passes through the chute and is fixedly connected to the output rod of the driving cylinder. The workpiece is fixedly connected to the clamping slide. The second polishing module passes through the guide seat and is rotatably connected to the guide seat.

[0010] The clamping slide is responsible for clamping and fixing the workpiece, and the clamping slide will drive the workpiece to rotate. The driving cylinder is the driving element of the sliding module. When the driving cylinder is started, the output rod of the driving cylinder pushes the clamping slide, and the clamping slide slides along the slide bar until the workpiece is brought to the position to be polished.

[0011] Furthermore, a through hole is provided at one end of the guide seat. The through hole of the guide seat is located directly above the funnel groove. The two sides of the guide seat are provided with inclined surfaces, and the downhill directions of the inclined surfaces on both sides of the guide seat lead to the through hole.

[0012] The inclined surfaces on both sides of the guide seat facilitate the collection of debris. Under the vibration generated during the operation of the air blowing module and the polishing device, some debris will flow along the inclined surfaces on both sides of the guide seat towards the through hole and finally fall into the funnel groove.

[0013] Furthermore, the first polishing module includes a lifting table, a first motor, and a first polishing disc. The lifting table is fixedly connected to the workbench and is located on one side of the protective cover. The first motor is fixedly connected to the lifting table. The output rod of the first motor passes through the protective cover and is rotationally connected to the detection and compensation module. The first polishing disc is fixedly connected to the output rod of the first motor.

[0014] The lifting table drives the first motor and the first polishing disc to move up and down in the vertical direction. The first motor drives the first polishing disc to polish the upper surface of the workpiece. The rotation direction of the first motor is such that when the first polishing disc polishes, the debris splashes towards the funnel groove and is opposite to the rotation direction of the workpiece. During polishing, most of the debris impacts on the protective cover and then falls into the funnel groove, reducing the frequency of manual debris cleaning.

[0015] Furthermore, the second polishing module includes a second motor and a second polishing disc. The second motor is fixedly connected to the workbench and is located below the workbench. The output rod of the second motor sequentially passes through the workbench and the guide seat. The output rod of the second motor is rotationally connected to the workbench and the guide seat respectively. The rotation direction of the output rod of the second motor is the opposite clockwise direction to that of the first motor. The second polishing disc is fixedly connected to the output rod of the second motor and is located above the guide seat.

[0016] The second motor drives the second polishing disc to polish the side surface of the workpiece. The rotation direction of the second motor is the same as the rotation direction of the workpiece. During polishing, some of the debris generated is blocked by the protective cover, and the other part of the debris is blown by the air blowing module and impacts on the side surface of the workpiece in a state tangent to the side surface of the workpiece, preventing the other part of the debris from damaging the side surface of the workpiece.

[0017] Furthermore, the air blowing module includes a blower box and an air blowing pipe. The blower box is fixedly connected to the workbench and is located on the other side of the protective cover. One end of the air blowing pipe is communicated with the air outlet of the blower box, and the other end of the air blowing pipe is communicated with an inlet of the protective cover.

[0018] The blower box is communicated with the protective cover through the air blowing pipe. The blower box blows air so that some of the debris generated during polishing impacts on the side surface of the workpiece in a state tangent to the side surface of the workpiece, preventing it from damaging the side surface of the workpiece.

[0019] Further, the detection and compensation module includes a fixing bar, a spring, a magnetic rod, a first coil, a connecting piece, a second coil, and a third coil. The fixing bar is fixedly connected to the protective cover. The fixing bar is provided with a first groove and a second groove. A first annular baffle is arranged in the first groove. The second coil is arranged in the first groove and wraps the first annular baffle. The connecting piece is inserted into the first annular baffle and is slidably connected to the first annular baffle. The first annular baffle completely separates the second coil and the connecting piece. A second annular baffle is arranged in the second groove. The third coil is arranged in the second groove and wraps the second annular baffle. The connecting piece is inserted into the second annular baffle and is slidably connected to the second annular baffle. The second annular baffle completely separates the third coil and the connecting piece. The connecting piece is slidably connected to the fixing bar and is rotatably connected to the output rod of the first motor. One end of the spring is fixedly connected to the connecting piece, and the other end of the spring is fixedly connected to the magnetic rod. The magnetic rod is inserted into the fixing bar and is slidably connected to the fixing bar. The first coil is fixedly connected to the fixing bar and wraps the magnetic rod. The first coil, the second coil, and the third coil are connected in series to form a complete circuit.

[0020] The first groove, the first annular baffle, and the connecting piece form a chamber, and the second groove, the second annular baffle, and the connecting piece form another chamber. Magnetorheological fluid is provided in both chambers. When the first motor drives the first polishing disc to polish, vibrations will be generated. The spring amplifies the vibrations at one end of the output rod of the first motor. The magnetic rod moves up and down as the spring continuously stretches and rebounds, thereby cutting the magnetic induction lines of the first coil. Currents are generated on the first coil, the second coil, and the third coil. After currents are generated on the second coil and the third coil, magnetic fields will be generated around them. The magnetorheological fluid in the two chambers becomes viscous under the influence of the magnetic fields, and the resistance to the up and down sliding of the connecting piece becomes larger, realizing vibration damping for the first motor and ensuring the polishing accuracy.

[0021] Further, the protective cover is provided with a first arc plate and a second arc plate. The first arc plate and the second arc plate are fixedly connected. The first arc plate is located directly above the workpiece, and the arc-shaped surface of the first arc plate coincides with the outer ring surface of the workpiece. The first arc plate is fixedly connected to the fixing bar. The protective cover is provided with a connection port, and the connection port communicates with the air duct formed by the first arc plate and the second arc plate. The connection port is communicated with the air blowing pipe.

[0022] The arc-shaped surface of the first arc plate coincides with the outer ring surface of the workpiece. The gas blown out by the air blowing module blows along the arc-shaped surface of the first arc plate towards the outer ring surface of the workpiece, realizing precise guidance while making the air flow uniform, making the air blowing effect more stable and efficient, and playing a certain protective role for the side of the workpiece.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. A funnel groove is provided on the workbench of the present invention, and inclined surfaces are provided on both sides of the guide seat. Under the vibration generated when the air blowing module and the polishing device are working, part of the debris flows along the inclined surfaces on both sides of the guide seat towards the through hole, and finally falls into the funnel groove for collection and discharge, realizing self-cleaning of the polishing device, reducing the frequency of manual cleaning by workers, and improving work efficiency;

[0025] 2. Through the air blowing module, the first arc-shaped plate and the second arc-shaped plate, the present invention enables part of the debris generated during polishing to impact on the side surface of the workpiece in a state tangent to the side surface of the workpiece, so that it cannot cause damage to the side surface of the workpiece;

[0026] 3. The present invention detects the vibration generated during polishing by the first polishing module through the inspection and compensation module, and performs active compensation to slow down the amplitude of the vibration and ensure the polishing accuracy.

Detailed implementation mode

[0036] Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment: As Figure 1 - Figure 7 shown, the present invention provides a technical solution for a polishing device for metal castings with a self-cleaning function:

[0038] As Figure 1 、 Figure 2 、 Figure 5 and Figure 6 shown, the polishing device includes a workbench 1, a sliding module 2, a first polishing module 3, a second polishing module 4, an air blowing module 5, a detection and compensation module 6, a protective cover 7 and a workpiece 8. A chute 11 is arranged on the workbench 1. The protective cover 7 is fixedly connected to the upper end surface of the workbench 1 and is located at one end of the workbench 1. The sliding module 2 passes through the chute 11 and is fixedly connected to the workbench 1. One end of the sliding module 2 is inserted into the protective cover 7. The workpiece 8 is fixedly connected to the sliding module 2. The first polishing module 3 is fixedly connected to the workbench 1 and is inserted into the protective cover 7. The second polishing module 4 passes through the workbench 1 and the sliding module 2 in sequence and is inserted into the protective cover 7. The second polishing module 4 is located between the workpiece 8 in the polishing state and one end of the workbench 1. The air blowing module 5 is fixedly connected to the workbench 1 and is in pipeline communication with the protective cover 7. The detection and compensation module 6 is fixedly connected to the protective cover 7 and is located inside the protective cover 7. One end of the first polishing module 3 is rotatably connected to the detection and compensation module 6.

[0039] The sliding module 2 is responsible for clamping the workpiece 8 and then transporting it to the polishing position for polishing. The first polishing module 3 is responsible for polishing the upper surface of the workpiece 8, and the second polishing module 4 is responsible for polishing the side of the workpiece 8. The air blowing module 5 is responsible for processing the debris flying around generated by the second polishing module 4 during polishing, blocking part of the debris to prevent the debris from hitting the workpiece 8 and affecting the polishing quality. At the same time, the other part of the debris that cannot be blocked is blown away so that when the debris hits the side of the workpiece 8, it is tangent to the side of the workpiece 8, reducing the impact force of the debris on the workpiece 8, and the air blowing module 5 can also blow the debris to one end of the workbench 1 to collect and clean the debris. The detection and compensation module 6 is responsible for detecting and actively compensating for the vibration generated by the first polishing module 3 during grinding, reducing the vibration amplitude of the first polishing module 3, so that the first polishing module 3 does not have a large angle deviation during polishing, and ensuring the polishing quality. The protective cover 7 can prevent debris and dust from flying around.

[0040] like Figure 3 As shown, a funnel groove 12 is provided at one end of the workbench 1 , and the funnel groove 12 is located in the protective cover 7 and on the side of the second polishing module 4 facing away from the workpiece 8 .

[0041] The funnel groove 12 can collect debris generated during polishing. During the operation of the polishing device, the entire device will produce slight vibrations. Under the action of the vibration, the debris will be collected and discharged along the inner wall of the funnel-shaped funnel groove 12 to the central outlet of the funnel groove 12, thereby realizing self-cleaning of the polishing device.

[0042] like Figure 4 and Figure 5 As shown, the sliding module 2 includes a driving cylinder 21, a clamping slide 22, a sliding rod 23, a fixed seat 24 and a guide seat 25. The guide seat 25 is fixedly connected to one end of the workbench 1 and is located in the protective cover 7. The fixed seat 24 is fixedly connected to the other end of the workbench 1. One end of the sliding rod 23 is inserted into the protective cover 7 and fixedly connected to the guide seat 25. The other end of the sliding rod 23 is fixedly connected to the fixed seat 24. The clamping slide 22 is slidably connected to the sliding rod 23. The clamping slide 22, the sliding rod 23, the fixed seat 24 and the guide seat 25 are all located above the workbench 1. The driving cylinder 21 is fixedly connected to the lower end surface of the workbench 1. The clamping slide 22 passes through the slide groove 11 and is fixedly connected to the output rod of the driving cylinder 21. The workpiece 8 is fixedly connected to the clamping slide 22. The second polishing module 4 passes through the guide seat 25 and is rotatably connected to the guide seat 25.

[0043] The clamping slider 22 is responsible for clamping and fixing the workpiece 8, and the clamping slider 22 will drive the workpiece 8 to rotate. The driving cylinder 21 is the driving element of the sliding module 2. When the driving cylinder 21 is started, the output rod of the driving cylinder 21 pushes the clamping slider 22, and the clamping slider 22 slides along the slide bar 23 until the workpiece 8 is brought to the position to be polished.

[0044] As Figure 3 and Figure 4 shown, one end of the guiding seat 25 is provided with a through hole. The through hole of the guiding seat 25 is located directly above the funnel groove 12. The two sides of the guiding seat 25 are provided with inclined surfaces, and the downhill directions of the inclined surfaces on both sides of the guiding seat 25 lead to the through hole.

[0045] The inclined surfaces on both sides of the guiding seat 25 facilitate the collection of debris. Under the vibration generated when the air blowing module 5 and the polishing device are working, some debris will flow along the inclined surfaces on both sides of the guiding seat 25 towards the through hole and finally fall into the funnel groove 12.

[0046] As Figure 3 and Figure 6 shown, the first polishing module 3 includes a lifting table 31, a first motor 32 and a first polishing disc 33. The lifting table 31 is fixedly connected to the workbench 1 and is located on one side of the protective cover 7. The first motor 32 is fixedly connected to the lifting table 31. The output rod of the first motor 32 is inserted into the protective cover 7 and is rotationally connected to the detection and compensation module 6. The first polishing disc 33 is fixedly connected to the output rod of the first motor 32.

[0047] The lifting table 31 drives the first motor 32 and the first polishing disc 33 to move up and down in the vertical direction. The first motor 32 drives the first polishing disc 33 to polish the upper surface of the workpiece 8. The rotation direction of the first motor 32 is such that when the first polishing disc 33 is polishing, the debris splashes towards the direction of the funnel groove 12 and is opposite to the rotation direction of the workpiece 8. Most of the debris hits the protective cover 7 during polishing and then falls into the funnel groove 12, reducing the frequency of manual debris cleaning.

[0048] As Figure 5 shown, the second polishing module 4 includes a second motor 41 and a second polishing disc 42. The second motor 41 is fixedly connected to the workbench 1 and is located below the workbench 1. The output rod of the second motor 41 passes through the workbench 1 and the guiding seat 25 in sequence. The output rod of the second motor 41 is rotationally connected to the workbench 1 and the guiding seat 25 respectively. The rotation direction of the output rod of the second motor 41 and the first motor 32 is the opposite clockwise direction. The second polishing disc 42 is fixedly connected to the output rod of the second motor 41 and is located above the guiding seat 25.

[0049] The second motor 41 drives the second polishing disc 42 to polish the side surface of the workpiece 8. The rotation direction of the second motor 41 is the same as that of the workpiece 8. Part of the debris generated during polishing is blocked by the protective cover 7, and the other part of the debris is blown by the air blowing module 5 and impacts on the side surface of the workpiece 8 in a state tangent to the side surface of the workpiece 8, so that the other part of the debris cannot damage the side surface of the workpiece 8.

[0050] As Figure 1 shown, the air blowing module 5 includes a blower box 51 and an air blowing pipe 52. The blower box 51 is fixedly connected to the workbench 1 and is located on the other side of the protective cover 7. One end of the air blowing pipe 52 is communicated with the air outlet of the blower box 51, and the other end of the air blowing pipe 52 is communicated with an inlet of the protective cover 7.

[0051] The blower box 51 is communicated with the protective cover 7 through the air blowing pipe 52. The blower box 51 blows air so that part of the debris generated during polishing impacts on the side surface of the workpiece 8 in a state tangent to the side surface of the workpiece 8, making it impossible to damage the side surface of the workpiece 8.

[0052] As Figure 7 shown, the detection and compensation module 6 includes a fixing strip 61, a spring 62, a magnetic rod 63, a first coil 64, a connecting piece 65, a second coil 66 and a third coil 67. The fixing strip 61 is fixedly connected to the protective cover 7. A first groove 68 and a second groove 69 are provided in the fixing strip 61. A first annular baffle 610 is provided in the first groove 68. The second coil 66 is arranged in the first groove 68 and wraps the first annular baffle 610. The connecting piece 65 is inserted into the first annular baffle 610 and is slidably connected to the first annular baffle 610. The first annular baffle 610 completely separates the second coil 66 and the connecting piece 65. A second annular baffle 611 is provided in the second groove 69. The third coil 67 is arranged in the second groove 69 and wraps the second annular baffle 611. The connecting piece 65 is inserted into the second annular baffle 611 and is slidably connected to the second annular baffle 611. The second annular baffle 611 completely separates the third coil 67 and the connecting piece 65. The connecting piece 65 is slidably connected to the fixing strip 61 and is rotatably connected to the output rod of the first motor 32. One end of the spring 62 is fixedly connected to the connecting piece 65, and the other end of the spring 62 is fixedly connected to the magnetic rod 63. The magnetic rod 63 is inserted into the fixing strip 61 and is slidably connected to the fixing strip 61. The first coil 64 is fixedly connected to the fixing strip 61 and wraps the magnetic rod 63. The first coil 64, the second coil 66 and the third coil 67 are connected in series to form a complete circuit.

[0053] The first groove 68, the first annular baffle 610 and the connecting member 65 form a chamber, and the second groove 69, the second annular baffle 611 and the connecting member 65 form another chamber. Magnetorheological fluid is provided in both chambers. When the first motor 32 drives the first polishing disc 33 for polishing, vibrations will be generated. The spring 62 amplifies the vibrations at one end of the output rod of the first motor 32. The magnetic rod 63 moves up and down as the spring 62 continuously stretches and rebounds, thereby cutting the magnetic induction lines of the first coil 64. Currents are generated in the first coil 64, the second coil 66 and the third coil 67. After currents are generated in the second coil 66 and the third coil 67, magnetic fields will be generated around them. The magnetorheological fluid in the two chambers becomes viscous under the influence of the magnetic fields, and the resistance to the up-and-down sliding of the connecting member 65 becomes larger, realizing vibration damping for the first motor 32 and ensuring the polishing accuracy.

[0054] As Figure 8 shown, the protective cover 7 is provided with a first arc plate 71 and a second arc plate 72. The first arc plate 71 and the second arc plate 72 are fixedly connected. The first arc plate 71 is located directly above the workpiece 8. The arc-shaped curved surface of the first arc plate 71 coincides with the outer ring curved surface of the workpiece 8. The first arc plate 71 is fixedly connected to the fixing strip 61. The protective cover 7 is provided with a connection port 73. The connection port 73 is communicated with the air duct formed by the first arc plate 71 and the second arc plate 72. The connection port 73 is communicated with the air blowing pipe 52.

[0055] The arc-shaped curved surface of the first arc plate 71 coincides with the outer ring curved surface of the workpiece 8. The gas blown out by the air blowing module 5 blows along the arc-shaped curved surface of the first arc plate 71 towards the outer ring curved surface of the workpiece 8. While achieving precise guidance, the air flow is made uniform, making the air blowing effect more stable and efficient, and playing a certain protective role for the side surface of the workpiece 8.

[0056] The working principle of the present invention: The sliding module 2 is responsible for clamping the workpiece 8 and then transporting it to the position to be polished for polishing. The first polishing module 3 is responsible for polishing the upper surface of the workpiece 8. The second polishing module 4 is responsible for polishing the side surface of the workpiece 8. The air blowing module 5 is responsible for dealing with the debris splashing everywhere generated during the polishing of the second polishing module 4, blocking some of the debris and preventing the debris from hitting the workpiece 8, thereby affecting the polishing quality. At the same time, the other part of the debris that cannot be blocked is blown, so that when the debris hits the side surface of the workpiece 8, it presents a state tangent to the side surface of the workpiece 8, reducing the impact force of the debris on the workpiece 8. Moreover, the air blowing module 5 can also blow the debris towards one end of the workbench 1 to realize the collection and cleaning of the debris. The detection and compensation module 6 is responsible for detecting the vibrations generated during the grinding of the first polishing module 3 and making active compensation, reducing the vibration amplitude of the first polishing module 3, so that the first polishing module 3 does not have a large angular deviation during polishing, ensuring the polishing quality. The protective cover 7 can prevent the debris and dust from splashing everywhere.

[0057] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
