[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figures 1 to 4As shown, a gear processing and grinding device according to an embodiment of the present invention comprises a workbench 1; a turntable 2 is rotatably connected to the top surface of the workbench 1, and the turntable 2 is driven by a servo motor drive 1; two pairs of evenly arranged mounting seats 3 are rotatably arranged on the top surface of the turntable 2, and the mounting seats 3 are driven by a servo motor 2; a tray 4 is rotatably connected to the top surface of the mounting seats 3, and the tray 4 is driven by a servo motor 3; a stud 5 is rotatably connected to the top surface of the tray 4; both ends of the stud 5 are threadedly connected to support columns 6, and the support columns 6 and the mounting seats are connected. 3 is slidably connected; the top surface of the supporting column 6 is fixedly connected with a clamping rod 7, and the diameter of the clamping rod 7 is smaller than the diameter of the supporting column 6; the top surface of the workbench 1 is slidably connected with a support frame 8; the support frame 8 is driven by a linear motor 1, and the support frame 8 is located on the top of the turntable 2; the top of the support frame 8 is slidably connected to a support arm 9, and the support arm 9 is driven by a hydraulic system; the bottom of the support arm 9 is rotatably connected to a drive rod 10, and the drive rod 10 is driven by a servo motor 4; a grinding disc 11 is installed at the end of the drive rod 10;During operation, in order to improve the efficiency of grinding the gear, the embodiment of the present invention can be used. First, the user needs to screw the two opposite studs 5, and the studs 5 drive the paired supporting columns 6 and the clamping rod 7 to approach each other. Then, the user can put the gear to be ground on the surface of the paired clamping rod 7, and the bottom is placed on the top surface of the supporting columns 6. Then, the user screws the studs 5 again, and the studs 5 drive the paired supporting columns 6 and the clamping rod 7 to move away from each other, so that the clamping rod 7 is tightly against the inner wall of the gear. After the gears are polished, the user can install another gear on the top surface of another pair of mounting seats 3, and when the polishing of the gear is completed, the turntable 2 rotates and cooperates with the movement of the mounting seats 3 to make the gears contact with the polishing disc 11. The polished gear is removed from the polishing disc 11, while the other gear to be polished is moved to the polishing disc 11, thereby starting the next round of polishing operation. Therefore, through the cooperation of the turntable 2, the mounting base 3, the tray 4, the stud 5, the supporting column 6, the clamping rod 7 and the polishing disc 11, the polishing disc 11 can polish two gears at a time, thereby improving the gear polishing efficiency. During the gear polishing, the user can also load another pair of gears, thereby further improving the gear polishing efficiency.

[0023] like Figure 1 、 Figure 3 and Figure 4As shown, the surface of the support arm 9 is provided with a mounting hole 12 at the top of the driving rod 10; a transmission gear 13 is rotatably connected in the mounting hole 12, and the transmission gear 13 is driven by the servo motor 5; the mounting holes 12 are extended at both ends of the transmission gear 13; the two sides of the support arm 9 are slidably connected with a toothed plate 14; the two toothed plates 14 are meshed with the transmission gear 13 and are respectively located on both sides of the transmission gear 13; the bottom of the toothed plate 14 is fixedly connected with a connecting seat 15; the grinding disc 11 is provided with a pair, and the two grinding discs 11 are connected to the connecting seat 15 through a connecting assembly; the connecting assembly is also used for connecting the grinding disc 11 to the driving rod 10; during work, after the grinding disc 11 grinds the gear for a long time, its surface will inevitably be worn out, and in order to achieve the grinding effect of the gear later, the grinding disc 11 needs to be replaced, and for this reason the user needs to control the rotation of the transmission gear 13 at the mounting hole 12 The gear plates 14 on both sides of the transmission gear 13 are driven to rise and fall, thereby raising the gear plate 14 on one side of the grinding disc 11 to be replaced, and the raised gear plate 14 will also drive the grinding disc 11 to be replaced to rise through the connecting seat 15 and the connecting rod 16, while the grinding disc 11 on the other side that is not worn will be moved to the driving rod 10 of the support arm 9 under the drive of the gear plate 14, and then the connecting assembly at the driving rod 10 will complete the connection between the driving rod 10 and the connecting rod 16, so that the grinding disc 11 can be driven by the driving rod 10, and then the support frame 8 slides, so that the grinding disc 11 can be moved between the two gears to be polished, and then continue the subsequent polishing operation. Therefore, through the cooperation of the transmission gear 13, the gear plate 14, the connecting seat 15 and the connecting rod 16, the worn grinding disc 11 can be quickly replaced, avoiding the long delay in the grinding of the gears due to the long replacement time of the grinding disc 11, thereby affecting the grinding efficiency of the gear.

[0024] like Figures 3 to 6As shown, the connecting assembly includes a connecting rod 16; the surface of the connecting rod 16 is rotatably connected to the bottom of the tooth plate 14; both ends of the driving rod 10 are installed with ejection type air slip rings 17; the telescopic end of the ejection type air slip ring 17 is fixedly connected with an insertion rod 18; the end of the connecting rod 16 close to the support arm 9 is provided with a slot 19; the bottom of the slot 19 is installed with a magnet column 20, and the insertion rod 18 is made of magnetizable metal; during operation, when the connecting rod 16 needs to be connected to the driving rod 10, the driving rod 10 will push the insertion rod 18 toward the connecting rod through the ejection type air slip ring 17. The slot 19 on the surface of the connecting rod 16 moves, and finally the insertion rod 18 is inserted into the slot 19. Since the insertion rod 18 is made of magnetizable metal, the insertion rod 18 will be adsorbed by the magnet column 20, and then the magnet column 20, the insertion rod 18 and the connecting rod 16 are connected as a whole. After that, the driving rod 10 can drive the telescopic end of the ejection type air slip ring 17, the insertion rod 18 and the connecting rod 16 to rotate together, and finally drive the grinding disk 11 to rotate. Therefore, during the entire connection process, no manual operation is required by the user, which reduces the operating difficulty of the user and improves the efficiency of replacement.

[0025] like Figures 5 and 6 As shown, the end of the insertion rod 18 close to the magnet column 20 is fixedly connected with two pairs of evenly arranged abutment plates 21, and the thickness of the abutment plates 21 close to the magnet column 20 is greater than the thickness of the side away from the magnet column 20; the abutment plates 21 are arranged in an arc shape and are elastic; the end of the magnet column 20 away from the bottom of the slot 19 is fixedly connected with a magnetic ball 22; during operation, when the insertion rod 18 is inserted into the slot 19, the magnetic ball 22 at the end of the magnet column 20 will squeeze the abutment plates 21 at the end of the insertion rod 18, and spread the four abutment plates 21 to the four sides, and finally make the abutment plates 21 be pressed against the inner wall of the slot 19, thereby increasing the maximum static friction between the two, thereby further improving the stability of the connection between the insertion rod 18 and the connecting rod 16, and avoiding relative sliding between the two.

[0026] like Figures 6 and 7As shown, a threaded hole 23 is provided at one end of the connecting rod 16 away from the support arm 9; a threaded rod 24 is connected to the threaded hole 23 through a thread; two pairs of evenly arranged ejection grooves 25 are provided on the surface of the connecting rod 16, and the ejection grooves 25 are connected to the threaded hole 23; a clamping plate 26 is slidably connected to the ejection groove 25, and the clamping plate 26 is located on one side of the ejection groove 25 and is inclined; a clamping groove 261 is provided on the inner wall of the grinding disc 11 at a corresponding position of the clamping plate 26; during operation, when the user needs to remove the worn grinding disc 11, the user needs to screw the threaded rod 24 at the end of the connecting rod 16 until the threaded rod 24 is out of the threaded hole 23, at which time the clamping plate 26 is no longer squeezed by the threaded rod 24, and then the user The clamping plate 26 can be pressed back into the ejection groove 25, so that the clamping plate 26 no longer squeezes the clamping groove 261 on the inner wall of the grinding disc 11, so the user can easily remove the grinding disc 11 from the surface of the connecting rod 16 and replace it with a new grinding disc 11, and align the clamping groove 261 on the inner wall of the grinding disc 11 with the ejection groove 25 on the surface of the connecting rod 16, and then screw the threaded rod 24 into the threaded hole 23 again. In the process of screwing the threaded rod 24 into the threaded hole 23, the clamping plate 26 in the ejection groove 25 will be ejected out of the ejection groove 25 and reinserted into the clamping groove 261, thereby further improving the stability of the connection between the connecting rod 16 and the grinding disc 11, and preventing the grinding disc 11 and the connecting rod 16 from rotating relative to each other when the connecting rod 16 rotates.

[0027] like Figure 6 As shown, the surface of the connecting rod 16 is fixedly connected with a rubber sleeve 27 at the position of the ejection groove 25; the notch of the said card slot 261 is fixedly connected with an elastic band 28; the side of the elastic band 28 away from the card plate 26 is fixedly connected to the inner wall of the rubber sleeve 27; when working, when the card plate 26 is ejected from the ejection groove 25, the card plate 26 will squeeze the elastic band 28 and the rubber sleeve 27 and squeeze the two together into the card slot 261. Since the rubber sleeve 27 is elastic, it can effectively fill the gap between the card plate 26 and the card slot 261, thereby avoiding the connection. When the connecting rod 16 drives the grinding disc 11 to rotate, the clamping plate 26 and the clamping slot 261 collide due to the gap, which causes the grinding disc 11 to vibrate, thereby affecting the grinding accuracy of the grinding disc 11 on the gear. When the threaded rod 24 is out of the threaded hole 23, the elastic band 28 squeezed by the clamping plate 26 will recover, and then press the clamping plate 26 back into the ejection slot 25. Therefore, the user does not need to manually press the clamping plate 26 back into the ejection slot 25, thereby simplifying the user's operation and reducing the operating difficulty of the embodiment of the present invention.

[0028] like Figure 1 、 Figure 3 and Figure 8As shown, a support plate 29 is fixedly connected to the bottom surface of the support arm 9; both ends of the support plate 29 are fixedly connected to an insert plate 30; the bottom surfaces of the two connecting seats 15 are provided with connecting grooves 31 at the corresponding positions of the insert plates 30; during operation, when the tooth plate 14 drives the connecting seat 15 to descend, the insert plates 30 at the ends of the support plate 29 will be inserted into the connecting grooves 31 on the bottom surface of the connecting seat 15, and the support plate 29 will also be supported on the bottom surface of the connecting seat 15, so that the support plate 29 can cooperate with the tooth plate 14 to clamp the connecting seat 15, and the insert plates 30 limit the vibration of the connecting seat 15, thereby ensuring the grinding accuracy of the grinding disc 11.

[0029] like Figure 8 As shown, a rubber pad 32 is fixedly connected to the inner wall of the connecting groove 31; the bottom thickness of the rubber pad 32 is less than the top thickness; during operation, when the plugboard 30 is inserted into the connecting groove 31, the opening at the top of the rubber pad 32 gradually shrinks, so the plugboard 30 is eventually clamped by the rubber pad 32, thereby further improving the stability of the connection between the two.

[0030] like Figure 1 、 Figure 2 and Figure 9 As shown, the top surface of the workbench 1 is slidably connected to a movable seat 33 on both sides of the turntable 2; the two movable seats 33 are driven by a linear motor 2, and the connecting line of the two movable seats 33 is perpendicular to the support frame 8; the top surface of the movable seat 33 is rotatably connected to a rotating rod 34, and the rotating rod 34 is driven by a servo motor 6; the rotating rod 34 is provided with a groove 35 on the side close to the turntable 2, and the groove 35 has a notch and a bottom in a regular hexagonal shape; the stud 5 is fixedly connected to a limiting column 36 on the side away from the support arm 9 , and the limiting column 36 is set in a regular hexagonal prism; during operation, when the stud 5 needs to be screwed, the two moving seats 33 will move toward the mounting seat 3 under the drive of the linear motor 2, and finally the groove 35 at the end of the rotating rod 34 will be sleeved on the limiting column 36 at the end of the stud 5, and then the servo motor 6 will drive the rotating rod 34 to rotate, and the limiting column 36 and the stud 5 can be driven to rotate by the rotating rod 34, thereby quickly releasing the fixation of the top gears of the two mounting seats 3, thereby improving the efficiency of the user in unloading the gears.

[0031] like Figure 1 and Figure 9As shown, the top surface of the movable seat 33 is rotatably connected to an electric push rod 37, and the electric push rod 37 is driven by a servo motor 7; the top of the electric push rod 37 is fixedly connected to a support plate 38; the bottom surface of the support plate 38 is provided with a pair of symmetrically arranged vacuum suction cups 39, and the vacuum suction cups 39 are fixedly connected to the support plate 38 by bolts; the top surface of the workbench 1 is provided with conveyor belts 40 on both sides of the movable seat 33; during operation, when the gear polished on the top surface of the mounting seat 3 is released, the electric push rod 37 will drive the support plate 38 to rotate to the top surface of the released gear, and then the movable seat 33 moves, so that the vacuum suction cups 39 on the surface of the support plate 38 can The top surface of the gear is aligned, and then the electric push rod 37 drives the support plate 38 and the vacuum suction cup 39 thereon to descend, and the vacuum suction cup 39 can fit on the top surface of the gear and adsorb the gear. Then the electric push rod 37 rises, so that the gear is completely separated from the clamping rod 7 and the supporting column 6, and then the electric push rod 37 rotates again to move the adsorbed gear to the conveyor belt 40 on one side, and then the electric push rod 37 adsorbs the gear to be polished on the other side of the conveyor belt 40 through the support plate 38 and the vacuum suction cup 39, and moves it to the mounting seat 3, thereby completing the loading operation, thereby realizing automatic loading and unloading of the gear, thereby further improving the grinding efficiency.

[0032] During operation, in order to improve the efficiency of grinding the gear, the embodiment of the present invention can be used. First, the user needs to screw the two opposite studs 5, and the studs 5 drive the paired supporting columns 6 and the clamping rod 7 to approach each other. Then, the user can put the gear to be ground on the surface of the paired clamping rod 7, and the bottom is placed on the top surface of the supporting columns 6. Then, the user screws the studs 5 again, and the studs 5 drive the paired supporting columns 6 and the clamping rod 7 to move away from each other, so that the clamping rod 7 is tightly against the inner wall of the gear. After the gears are polished, the user can install another gear on the top surface of another pair of mounting seats 3, and when the polishing of the gear is completed, the turntable 2 rotates and cooperates with the movement of the mounting seats 3 to make the gears contact with the polishing disc 11. The polished gear is removed from the polishing disc 11, and the other gear to be polished is just moved to the polishing disc 11, and then the next round of polishing operation is started. Therefore, through the cooperation of the turntable 2, the mounting seat 3, the tray 4, the stud 5, the supporting column 6, the clamping rod 7 and the polishing disc 11, the polishing disc 11 can polish two gears at a time, thereby improving the polishing efficiency of the gears. During the gear polishing, the user can also load another pair of gears, thereby further improving the polishing efficiency of the gears.

[0033] After the grinding disc 11 has been grinding the gear for a long time, its surface will inevitably be worn out. In order to improve the grinding effect of the gear in the future, the grinding disc 11 needs to be replaced. To this end, the user needs to control the transmission gear 13 at the mounting hole 12 to rotate, thereby driving the tooth plates 14 on both sides of the transmission gear 13 to rise and fall, thereby causing the tooth plate 14 on one side of the grinding disc 11 to be replaced to rise, and the rising tooth plate 14 will also drive the grinding disc 11 to be replaced to rise through the connecting seat 15 and the connecting rod 16, and the unworn grinding disc 11 on the other side will be driven by the tooth plate 14 to move to the driving rod of the support arm 9. 10, and then the connecting assembly at the driving rod 10 completes the connection between the driving rod 10 and the connecting rod 16, so that the grinding disc 11 can be driven by the driving rod 10, and then the support frame 8 slides, so that the grinding disc 11 can be moved between the two gears to be polished, and then continue the subsequent grinding operation. Therefore, through the cooperation of the transmission gear 13, the tooth plate 14, the connecting seat 15 and the connecting rod 16, the worn grinding disc 11 can be quickly replaced, avoiding the long delay of gear grinding due to the long replacement time of the grinding disc 11, thereby affecting the gear grinding efficiency.

[0034] When the connecting rod 16 needs to be connected to the driving rod 10, the driving rod 10 will push the insertion rod 18 toward the slot 19 on the surface of the connecting rod 16 through the ejection air slip ring 17, and finally insert the insertion rod 18 into the slot 19. Since the insertion rod 18 is made of magnetizable metal, the insertion rod 18 will be adsorbed by the magnet column 20, and then the magnet column 20, the insertion rod 18 and the connecting rod 16 are connected as a whole. After that, the driving rod 10 can drive the telescopic end of the ejection air slip ring 17, the insertion rod 18 and the connecting rod 16 to rotate together, and finally rotate with the grinding disk 11. Therefore, during the entire connection process, no manual operation is required by the user, which reduces the operating difficulty of the user and improves the efficiency of replacement.

[0035] During the process of inserting the insertion rod 18 into the slot 19, the magnetic ball 22 at the end of the magnet column 20 will squeeze the abutment plate 21 at the end of the insertion rod 18, and push the four abutment plates 21 outward, and finally make the abutment plates 21 pressed tightly against the inner wall of the slot 19, thereby increasing the maximum static friction between the two, thereby further improving the stability of the connection between the insertion rod 18 and the connecting rod 16, and avoiding relative sliding between the two.

[0036] When the user needs to remove the worn grinding disc 11, the user needs to screw the threaded rod 24 at the end of the connecting rod 16 until the threaded rod 24 is out of the threaded hole 23. At this time, the clamping plate 26 is no longer squeezed by the threaded rod 24. Then the user can press the clamping plate 26 back into the ejection groove 25. As a result, the clamping plate 26 no longer squeezes the clamping groove 261 on the inner wall of the grinding disc 11, so the user can easily remove the grinding disc 11 from the surface of the connecting rod 16 and replace it with a new grinding disc 11. The clamping groove 261 on the inner wall of the grinding disc 11 is aligned with the ejection groove 25 on the surface of the connecting rod 16, and then the threaded rod 24 is screwed back into the threaded hole 23. In the process of screwing the threaded rod 24 into the threaded hole 23, the clamping plate 26 in the ejection groove 25 will be ejected out of the ejection groove 25 and reinserted into the clamping groove 261, thereby further improving the stability of the connection between the connecting rod 16 and the grinding disc 11, and preventing the grinding disc 11 and the connecting rod 16 from rotating relative to each other when the connecting rod 16 rotates.

[0037] When the card plate 26 is pushed out of the ejection groove 25, the card plate 26 will squeeze the elastic band 28 and the rubber sleeve 27 and squeeze the two together into the card groove 261. Since the rubber sleeve 27 is elastic, it can effectively fill the gap between the card plate 26 and the card groove 261, thereby preventing the connecting rod 16 from driving the grinding disc 11 to rotate, and preventing the card plate 26 and the card groove 261 from colliding due to the gap, thereby causing the grinding disc 11 to vibrate, thereby affecting the grinding accuracy of the grinding disc 11 on the gear. When the threaded rod 24 is out of the threaded hole 23, the elastic band 28 squeezed by the card plate 26 will recover, and then press the card plate 26 back into the ejection groove 25. Therefore, the user does not need to manually press the card plate 26 back into the ejection groove 25, thereby simplifying the user's operation and reducing the operating difficulty of the embodiment of the present invention.

[0038] When the tooth plate 14 drives the connecting seat 15 to descend, the insert plate 30 at the end of the support plate 29 will be inserted into the connecting groove 31 on the bottom surface of the connecting seat 15, and the support plate 29 will also be supported on the bottom surface of the connecting seat 15. In this way, the support plate 29 can cooperate with the tooth plate 14 to clamp the connecting seat 15, and the insert plate 30 limits the vibration of the connecting seat 15, thereby ensuring the grinding accuracy of the grinding disc 11.

[0039] When the inserting plate 30 is inserted into the connecting groove 31 , the opening at the top of the rubber pad 32 gradually shrinks, so the inserting plate 30 is finally clamped by the rubber pad 32 , thereby further improving the stability of the connection between the two.

[0040] When the stud 5 needs to be screwed, the two movable seats 33 will move toward the mounting seat 3 under the drive of the linear motor 2, and finally the groove 35 at the end of the rotating rod 34 will be sleeved on the limiting column 36 at the end of the stud 5. Then the servo motor 6 drives the rotating rod 34 to rotate, and the limiting column 36 and the stud 5 can be driven to rotate through the rotating rod 34, thereby quickly releasing the fixation of the top gears of the two mounting seats 3, thereby improving the efficiency of the user in unloading the gears.

[0041] After the gear that has been polished on the top surface of the mounting seat 3 is released, the electric push rod 37 will drive the support plate 38 to rotate to the top surface of the released gear, and then the moving seat 33 will move so that the vacuum suction cup 39 on the surface of the support plate 38 can be aligned with the top surface of the gear, and then the electric push rod 37 will drive the support plate 38 and the vacuum suction cup 39 thereon to descend, and make the vacuum suction cup 39 fit on the top surface of the gear and adsorb the gear, and then the electric push rod 37 will rise, so that the gear is completely separated from the clamping rod 7 and the supporting column 6, and then the electric push rod 37 will rotate again to move the adsorbed gear to one side of the conveyor belt 40, and then the electric push rod 37 will adsorb the gear to be polished on the other side of the conveyor belt 40 through the support plate 38 and the vacuum suction cup 39, and move it to the mounting seat 3, thereby completing the loading operation, thereby realizing automatic loading and unloading of gears, thereby further improving the grinding efficiency.
