[0013] Technical effects and advantages of the present invention:

[0014] 1. The movable mechanism of the device, in which the cylinder drives the movable plate to move upward through the main telescopic rod, will drive the sliding frame to slide from back to front on the fixed slide rail. Since the toggle block is blocked by the sliding frame, it cannot rotate clockwise around the rotating rod ( Figure 7 As shown in the figure, when the toggle block slides from back to front, it will drive the work station disk to rotate one-seventh of a circle through the toggle notch groove, so as to realize the intermittent conversion of the work station disk. When the cylinder drives the main telescopic rod to extend, the movable plate will move downward. At this time, the movable plate will drive the sliding frame to slide from front to back on the fixed slide rail. Under the obstruction of the toggle notch groove, the toggle block can rotate counterclockwise ( Figure 7 As shown in the figure, the third spring will be compressed and will not drive the station disk to rotate. When the toggle block moves to the next set of toggle notches, the third spring will rebound. In this process, the rotation of the toggle block will drive the knocking mechanism to rotate through the rotating rod. At this time, the knocking plate will knock the workpiece at the fourth station to make the dust attached to the surface of the workpiece fall off. At the same time, the downward movement of the movable plate will press the pressure plate. On the one hand, the descent of the pressure plate will press the compression nozzle (the compression nozzle is an existing technology, similar to the pressing head of the existing detergent), so that the antiseptic in the liquid storage tank passes through the third connecting pipe and the compression nozzle. The first connecting pipe and the second supporting frame enter the sponge at the sixth station. The motor at the sixth station is started, which indirectly drives the workpiece at the sixth station to rotate. The surface of the workpiece will be coated with an anti-corrosion agent. On the other hand, the downward pressure of the movable plate will press the pressure plate, thereby lowering the liquid storage tank. Under the action of air pressure, the push rod will be pushed up. At this time, the push rod will push the extended protrusion at the seventh station, thereby pushing the workpiece upward. At this time, the manipulator can clamp the extended protrusion that is ejected to prevent the manipulator from directly grabbing the workpiece and causing damage to the anti-corrosion layer on the surface of the workpiece.

[0032] The present invention provides a polishing device for vehicle metal parts, including a base plate 1. A rotating mechanism 2 is fixedly connected to the upper end of the base plate 1. The rotating mechanism 2 includes a station plate 5. The lower end of the station plate 5 is rotatably connected to a support shaft 59, and the support shaft 59 is fixedly connected to the base plate 1. Seven groups of station grooves 48 are provided on the station plate 5. Each group of station grooves 48 rotatably connects a station table 39. Each group of station tables 39 is provided with a limiting groove 49. The first station 50, the second station 51, the third station 52, the fourth station 53, the fifth station 54, the sixth station 55 and the seventh station 56 are arranged in sequence clockwise on the station plate 5. A moving mechanism 3 is fixedly connected to the upper end of the base plate 1. A discharging mechanism 23 is fixedly connected to the upper end of the base plate 1. A coating mechanism 24 is arranged on one side of the discharging mechanism 23. Multiple groups of poking notch grooves 47 are provided on the station plate 5. A workpiece 8 is arranged on the upper end of the station table 39. An extension convex block 40 is fixedly connected to the lower end of the workpiece 8, and the extension convex block 40 is clamped with the limiting groove 49.

[0033] The moving mechanism 3 includes a main fixing frame 4. The main fixing frame 4 is fixedly connected to the base plate 1. A cylinder 10 is fixedly connected to the upper end of the main fixing frame 4. The lower end of the cylinder 10 extends to be provided with a main expansion rod 17. The lower end of the main expansion rod 17 is fixedly connected to a movable plate 18, and the movable plate 18 is slidably buckled with the main fixing frame 4 ( Figure 4As shown in the figure, the movable plate 18 is provided with an inclined track groove 19, and the front and rear sides of the main fixed frame 4 are fixedly connected with the same set of fixed slide rails 11, and one side of the fixed slide rail 11 is slidably connected with a knocking mechanism 16; the cylinder 10 can drive the movable plate 18 to rise or fall through the main telescopic rod 17, and because the knocking mechanism 16 slides with the inclined track groove 19 and the fixed slide rail 11 at the same time, when the movable plate 18 rises, the knocking mechanism 16 will slide from back to front along the fixed slide rail 11 (refer to Figure 1 );

[0034] The knocking mechanism 16 includes a sliding frame 28, and the sliding frame 28 is connected to the fixed slide rail 11 by sliding buckle. A guide rod 32 is fixedly connected to one side of the sliding frame 28, and the guide rod 32 is slidably connected to the inclined track groove 19. A rotating rod 33 is rotatably connected to the sliding frame 28, and a toggle block 29 is fixedly connected to the cylindrical outer surface of the rotating rod 33, and the toggle block 29 corresponds to the position of the toggle notch groove 47. A third spring 38 is fixedly connected between the toggle block 29 and the sliding frame 28 (the third spring 38 is used to toggle the block 29 The upper end of the rotating rod 33 is fixedly connected to a rotating frame 37, and one side of the rotating frame 37 is fixedly connected to multiple sets of second springs 35, and one side of the multiple sets of second springs 35 is fixedly connected to a knocking plate 36, and the knocking plate 36 is fixedly connected to the same side as the second spring 35 with a first limiting rod 34, and the first limiting rod 34 is slidably connected to the rotating frame 37; the upward movement of the movable plate 18 will drive the sliding frame 28 to slide from back to front on the fixed slide rail 11 (reference Figure 3 ), since the toggle block 29 is blocked by the sliding frame 28 and cannot rotate clockwise around the rotating rod 33 ( Figure 7 As shown in FIG. 1 , the toggle block 29 will drive the work station plate 5 to rotate one seventh of a circle through the toggle notch 47 when sliding from the back to the front (each back and forth movement of the toggle block 29 just drives the work station plate 5 to rotate one seventh of a circle); when the movable plate 18 moves downward, the movable plate 18 will drive the sliding frame 28 to slide from the front to the back on the fixed slide rail 11 (refer to FIG. 1 ). Figure 2 ), the toggle block 29 can rotate counterclockwise ( Figure 7 As shown in the figure, the third spring 38 will be compressed and will not drive the station plate 5 to rotate (because the limiting protrusion 7 will get stuck in the notch groove 47, when the sliding frame 28 slides from front to back, the toggle block 29 is not enough to break through the obstruction of the protrusion 7 and drive the station plate 5 to rotate). When the toggle block 29 moves to the next set of toggle notch grooves 47, the third spring 38 will rebound until the sliding frame 28 moves to the rear end on the fixed slide rail 11. The third spring 38 will rebound and drive the knocking plate 36 to knock the workpiece 8 out of the fourth station 53 through the rotating frame 37. The knocking will cause the residue on the surface of the workpiece 8 to fall off (dirt residue falls off);

[0035] The discharging mechanism 23 includes a sealing box 31, and the sealing box 31 is located directly below the movable plate 18. A sealing plate 57 is slidably connected inside the sealing box 31. The upper end of the sealing plate 57 is fixedly connected with a pressing plate 26. One side of the sealing box 31 is fixedly connected with a second connecting pipe 22. One end of the second connecting pipe 22 is fixedly connected with a sealing sleeve 15. The bottom end of the inner wall of the sealing sleeve 15 is fixedly connected with a fifth spring 58. The upper end of the fifth spring 58 is fixedly connected with a ejector rod 21, and the ejector rod 21 is located directly below the seventh station 56. The downward pressing of the movable plate 18 will press the pressing plate 26, thereby causing the pressing plate 26 to descend. Under the action of air pressure, the ejector rod 21 will be pushed upward. At this time, the ejector rod 21 will push the extension lug 40 at the seventh station 56, so that the workpiece 8 is pushed upward. At this time, the manipulator can clamp the extension lug 40 where the workpiece is ejected, preventing the manipulator from directly grasping the workpiece 8 (grasping the outer side of the workpiece 8), and causing damage to the anti-corrosion layer on the surface of the workpiece 8 (the outer side of the workpiece 8).

[0036] The coating mechanism 24 includes a liquid storage tank 27. One end of the liquid storage tank 27 is fixedly connected with a third connecting pipe 30. One end of the third connecting pipe 30 is fixedly connected with a compression spray head 25, and the compression spray head 25 is located directly below the pressing plate 26. One side of the compression spray head 25 is fixedly connected with a first connecting pipe 12. Two groups of second support frames 13 are fixedly connected to the upper end of the bottom plate 1, and the two groups of second support frames 13 are respectively located on one side of the fifth station 54 and the sixth station 55. One side of each group of second support frames 13 is fixedly connected with a sponge 14. The side of the second support frame 13 facing the sponge 14 is provided with leakage holes, and the second support frame 13 located on one side of the sixth station 55 is fixedly connected with the first connecting pipe 12. The motor 43 at the fifth station 54 is started, indirectly driving the workpiece 8 at the fifth station 54 to rotate (the driving gear 41 drives the station table 39 to rotate, thereby driving the workpiece 8 to rotate). The sponge 14 at the fifth station 54 can polish the residues on the surface of the workpiece 8. Since the movable plate 18 will press the pressing plate 26 during the descending process, the descending of the pressing plate 26 will press the compression spray head 25 (the compression spray head 25 is an existing technology, similar to the pressing head of existing detergents), so that the anti-corrosion agent in the liquid storage tank 27 passes through the third connecting pipe 30, the compression spray head 25, the first connecting pipe 12, and the second support frame 13 and enters the sponge 14 at the sixth station 55. The motor 43 at the sixth station 55 is started, indirectly driving the workpiece 8 at the sixth station 55 to rotate, and the surface of the workpiece 8 (the outer surface of the cylinder) will be coated with the anti-corrosion agent.

[0037] Two groups of first support frames 9 are fixedly connected to the upper end of the bottom plate 1, and the two groups of first support frames 9 correspond to the second station 51 and the third station 52 in position. Two groups of second limiting rods 44 are slidably connected to one side of each group of first support frames 9( Figure 8As shown), one end of the two groups of second limit rods 44 is fixedly connected with a grinding block 46, and multiple groups of fourth springs 45 are fixedly connected between the first support frame 9 and the grinding block 46, and the grinding block 46 located at the third station 52 has higher grinding accuracy than the grinding block 46 located at the second station 51 (the second station 51 is rough grinding, and the third station 52 is fine grinding); the motor 43 directly below the second station 51 is started, which indirectly drives the worktable 39 at the second station 51 to rotate, thereby driving the workpiece 8 thereon to rotate, and the workpiece 8 will be rough ground by the grinding block 46 at the second station 51, and similarly, the workpiece 8 will be fine ground by the grinding block 46 at the third station 52.

[0038] The upper end of the base plate 1 is fixedly connected to a fixing column 6, and the bottom end of the inner wall of the fixing column 6 is fixedly connected to a first spring 20. The upper end of the first spring 20 is fixedly connected to a limiting protrusion 7, and the limiting protrusion 7 corresponds to the position of the dial notch groove 47. The limiting protrusion 7 can block the rotation of the work station disk 5, so that the rotation of the work station disk 5 has to overcome a certain resistance, preventing the work station disk 5 from rotating by inertia, and at the same time preventing the pressure plate 26 from driving the work station disk 5 to rotate when moving from front to back.

[0039] Four groups of motors 43 are fixedly connected to the upper end of the base plate 1, and the four groups of motors 43 correspond to the second station 51, the third station 52, the fifth station 54 and the sixth station 55 respectively. A main shaft 42 is extended from the upper end of each group of motors 43, and a driving gear 41 is fixedly connected to the upper end of the main shaft 42, and the driving gear 41 is meshed with the station table 39; when the motor 43 is started, it will drive the driving gear 41 to rotate through the main shaft 42, thereby driving the station table 39 at the corresponding position to rotate, thereby driving the workpiece 8 at the corresponding position to rotate.

[0040] The device is located in the protective cover ( Figure 15 )Inside.

[0041] When doing specific work, Figure 1 The state shown is the initial state, and it is used as the reference view. When the device is in use, the manipulator first moves (clamps) the workpiece 8 to the workstation 39 at the first workstation 50, and the extension protrusion 40 is inserted into the limit groove 49. The cylinder 10 drives the main telescopic rod 17 to contract, and drives the movable plate 18 to move upward. Since the guide rod 32 slides in the inclined track groove 19, the upward movement of the movable plate 18 will drive the sliding frame 28 to slide from back to front on the fixed slide rail 11. Since the toggle block 29 is blocked by the sliding frame 28, it cannot rotate clockwise around the rotating rod 33 ( Figure 7 As shown in the figure, when the toggle block 29 slides from the back to the front, it drives the station plate 5 to rotate one seventh of a circle through the toggle notch groove 47. When the cylinder 10 drives the main telescopic rod 17 to extend, the movable plate 18 moves downward. At this time, the movable plate 18 drives the sliding frame 28 to slide from the front to the back on the fixed slide rail 11. Under the obstruction of the toggle notch groove 47, the toggle block 29 can rotate counterclockwise ( Figure 7As shown), the third spring 38 will be compressed and will not drive the work station disk 5 to rotate. When the toggle block 29 moves to the next set of toggle notch grooves 47, the third spring 38 will rebound until the slide frame 28 moves to the rear end on the fixed slide rail 11, and the workpiece 8 rotates to the second work station 51. At this time, the motor 43 directly below the second work station 51 is started, and the driving gear 41 is driven to rotate through the main shaft 42, thereby driving the work station table 39 at the second work station 51 to rotate, thereby driving the workpiece 8 thereon to rotate, and the workpiece 8 will be roughly ground by the grinding block 46 at the second work station 51. Repeating the steps will move the workpiece 8 to the third work station 52, and the motor 43 directly below the third work station 52 is started, and the workpiece 8 will be finely ground by the grinding block 46 at the third work station 52.

[0042] When the workpiece 8 rotates to the fourth station 53, when the sliding frame 28 slides from front to back, the rotation of the toggle block 29 will drive the knocking mechanism 16 to rotate through the rotating rod 33. At this time, the knocking plate 36 knocks the workpiece 8 at the fourth station 53, causing the dust attached to the surface of the workpiece 8 to fall off (dirt residue falls off).

[0043] When the workpiece 8 rotates to the fifth station 54 , the motor 43 at the fifth station 54 is started, which indirectly drives the workpiece 8 at the fifth station 54 to rotate, and the sponge 14 at the fifth station 54 can polish the residue on the surface of the workpiece 8 .

[0044] When the workpiece 8 rotates to the sixth station 55, the movable plate 18 will press the pressure plate 26 during the descent process, and the pressure plate 26 will press the compression nozzle 25 (the compression nozzle 25 is an existing technology, similar to the pressing head of the existing detergent), so that the preservative in the liquid storage tank 27 passes through the third connecting pipe 30, the compression nozzle 25, the first connecting pipe 12, and the second support frame 13, and enters the sponge 14 at the sixth station 55. The motor 43 at the sixth station 55 is started, which indirectly drives the workpiece 8 at the sixth station 55 to rotate, and the surface of the workpiece 8 (the outer side of the cylinder) will be coated with the preservative.

[0045] When the workpiece 8 rotates to the seventh station 56, the downward pressure of the movable plate 18 will press the pressure plate 26, thereby causing the liquid storage box 27 to drop. Under the action of air pressure, the push rod 21 will be pushed up. At this time, the push rod 21 will push the extension protrusion 40 at the seventh station 56, thereby pushing the workpiece 8 upward. At this time, the manipulator can clamp the extended protrusion 40 that is pushed out to complete the unloading, preventing the manipulator from directly grabbing the workpiece 8 (the outer side of the cylinder) and causing damage to the anti-corrosion layer on the surface of the workpiece 8 (the outer side of the cylinder); the entire process is completed in this cycle.

[0046] Finally: The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
