Technical Field

[0001] The utility model is applied to the field of product polishing, and particularly relates to a polishing device for thin-walled cylinders. Background Art

[0002] Most of the existing cylinder polishing devices are used to polish the outer circle, and do not polish the sealing part of the cross section of the polished workpiece. Moreover, the clamping methods are all internal support or external clamping methods. This fixing method is likely to cause deformation of thin-walled products. In addition, most polishing devices have dust isolation devices for precision components (such as lead screws, guide rails, etc.), which are likely to reduce the service life and cause damage to the equipment. Based on the above problems, if a polishing device that can provide dust isolation protection for precision components can be designed, and the polishing device adopts a clamping method that does not damage the appearance of the polished product, and can polish the cross-section sealing plate of the polished workpiece, then the above problems can be well solved.

[0021] As Figures 1 to 2 shown, in this embodiment, the utility model includes a frame 1, a product fixing module 2, a product side polishing module 3 and a product top surface polishing module 4. The product fixing module 2 and the product top surface polishing module 4 are both fixed on the frame 1. The product side polishing module 3 is slidably engaged with the frame 1. A product to be polished 5 is limit-engaged on the product fixing module 2. The product to be polished 5 is in frictional engagement with the product side polishing module 3 and the product top surface polishing module 4 in sequence. Thus, it can be seen that the frame 1 plays a role of supporting and fixing the product fixing module 2, the product side polishing module 3 and the product top surface polishing module 4. The product fixing module 2 plays a role of supporting and limiting the product to be polished 5, driving the product to be polished 5 to contact the product side polishing module 3 and the product top surface polishing module 4 respectively. The product side polishing module 3 and the product top surface polishing module 4 respectively perform polishing operations on the side and top surface of the product to be polished 5.

[0022] As Figures 3 to 4 shown, in this embodiment, the product fixing module 2 includes an X-axis guide rail 20, an X-axis servo motor 21, a first carrier plate 22, a Y-axis guide rail 23, a Y-axis servo motor 24 and a product fixing component 25. The X-axis guide rail 20 and the X-axis servo motor 21 are both fixed on the frame 1. The first carrier plate 22 is slidably engaged on the X-axis guide rail 20 under the traction of the X-axis servo motor 21. The Y-axis guide rail 23 and the Y-axis servo motor 24 are both fixed on the first carrier plate 22. The product fixing component 25 is slidably engaged on the Y-axis guide rail 23 under the traction of the Y-axis servo motor 24. Thus, it can be seen that the frame 1 plays a role of supporting and fixing the X-axis guide rail 20 and the X-axis servo motor 21. The X-axis servo motor 21 plays a role of a power source for the first carrier plate 22. The X-axis guide rail 20 plays a role of X-axis guiding for the first carrier plate 22. The Y-axis servo motor 24 plays a role of a power source for the product fixing component 25. The Y-axis guide rail 23 plays a role of Y-axis guiding for the product fixing component 25.

[0023] As Figure 5As shown, in the present embodiment, the product side polishing module 3 includes a pair of side polishing module fixing seats 30, four guiding slide rails 31, a pair of first driving motors 32, a pair of driving cylinders 33, a pair of grinding wheel fixing seats 34, a grinding wheel assembly 35, and a pair of grinding wheel covers 36. The side polishing module fixing seats 30 and the four guiding slide rails 31 are both fixed on the frame 1. A pair of driving cylinders 33 are fixed inside the frame 1. The pair of driving cylinders 33 respectively push the side polishing module fixing seats 30 to slide and cooperate on the guiding slide rails 31. A pair of first driving motors 32 and a pair of grinding wheel fixing seats 34 are respectively fixed on the pair of side polishing module fixing seats 30. The movable ends of the pair of first driving motors 32 pass through the grinding wheel fixing seats 34 and are rotationally matched with the grinding wheel assembly 35. The pair of grinding wheel covers 36 are respectively fixed on the pair of grinding wheel fixing seats 34. It can be seen that the frame 1 plays a role in supporting and fixing the pair of side polishing module fixing seats 30, the four guiding slide rails 31, and the pair of driving cylinders 33. The side polishing module fixing seats 30 play a role in supporting and limiting the first driving motors 32, the grinding wheel fixing seats 34, and the pair of grinding wheel covers 36. The grinding wheel fixing seats 34 play a role in supporting the grinding wheel assembly 35. The driving motors 32 play a role as a power source for the grinding wheel fixing seats 34. The grinding wheel assembly 35 plays a role in polishing the product 5 to be polished. The grinding wheel covers 36 play a role in blocking the impurities generated during the polishing of the product 5 to be polished, preventing the polished impurities from being thrown out and causing harm to the operator.

[0024] As Figure 7As shown, in this embodiment, the top surface polishing module 4 of the product includes a top surface polishing module fixing base 40, a second driving motor 41, a feeding tray 42, a material receiving tray 43, a convex plate 44, a plurality of abrasive paper guide rail assemblies 45, and abrasive polishing paper 46. The top surface polishing module fixing base 40 is fixed on the frame 1. The second driving motor 41, the feeding tray 42, the material receiving tray 43, the convex plate 44, and a plurality of the abrasive paper guide rail assemblies 45 are all arranged on the top surface polishing module fixing base 40. The second driving motor 41 is rotationally matched with the material receiving tray 43. The abrasive polishing paper 46 is arranged on the feeding tray 42. The abrasive polishing paper 46 is sequentially slidably matched on a plurality of the abrasive paper guide rail assemblies 45, the convex plate 44, and the material receiving tray 43. The other end of the abrasive polishing paper 46 is connected and matched with the material receiving tray 43. The abrasive polishing paper 46 is in frictional contact with the top surface of the product 5 to be polished at the convex plate 44. Thus, it can be seen that the top surface polishing module fixing base 40 plays a role in supporting and limiting the second driving motor 41, the feeding tray 42, the material receiving tray 43, the convex plate 44, and a plurality of the abrasive paper guide rail assemblies 45. The second driving motor 41 pushes the material receiving tray 43 to play a role in pulling and storing the abrasive polishing paper 46. The second driving motor 41 serves as a power source. The feeding tray 42 plays a role in pulling and storing the abrasive polishing paper 46. A plurality of the abrasive paper guide rail assemblies 45 play a role in guiding and limiting the abrasive polishing paper 46. The convex plate 44 makes the movement track of the abrasive polishing paper 46 protrude, so that it can better contact the top surface of the product 5 to be polished, improving the polishing efficiency of the top surface of the product to be polished.

[0025] As Figure 3 shown, in this embodiment, the product fixing module 2 further includes a first bellows 26 and a second bellows 27. One end of the first bellows 26 is fixed on the frame 1. The two ends of the first carrier plate 22 are respectively fixedly matched with the other end of the first bellows 26 and one end of the second bellows 27. The bottom surface of the other end of the first bellows 26 and the double-sided bottom surface of the second bellows 27 are slidably matched on the frame 1. Thus, it can be seen that the two ends of the first bellows 26 are fixed on the frame 1 and the first carrier plate 22. The shielding area of the first bellows 26 changes following the movement of the first carrier plate 22. The first bellows 26 plays a role in folding on the left side of the product fixing module 2. One side of the second bellows 27 is fixed on the right side of the first carrier plate 22, playing a role in shielding the X-axis guide rail 20 and the X-axis servo motor 21, so that the X-axis guide rail 20 and the X-axis servo motor 21 are not affected by the fine impurities generated during the polishing of the product 5 to be polished and their working performance.

[0026] As Figures 2 to 4As shown, in this embodiment, the product fixing assembly 25 includes a second carrier plate 80, a U-axis servo motor 81, a fixed-axis rotating seat 82, a vacuum suction assembly 83, and a workpiece fixing shaft 84. The U-axis servo motor 81, the fixed-axis rotating seat 82, and the vacuum suction assembly 83 are all fixed on the second carrier plate 80. The movable end of the U-axis servo motor 81 is rotationally engaged with the fixed-axis rotating seat 82. The other end of the fixed-axis rotating seat 82 is in limit cooperation with the workpiece fixing shaft 84. The workpiece fixing shaft 84 is in adsorption cooperation with the product to be polished 5 through the vacuum suction assembly 83. Thus, it can be seen that the second carrier plate 80 plays a role in supporting and limiting the U-axis servo motor 81, the fixed-axis rotating seat 82, and the vacuum suction assembly 83. The fixed-axis rotating seat 82 plays a role in limiting and supporting the workpiece fixing shaft 84. The movable end of the U-axis servo motor 81 drives the fixed-axis rotating seat 82 to rotate, and also drives the workpiece fixing shaft 84 to rotate. The U-axis servo motor 81 serves as a power source for rotation. The vacuum suction assembly 83 provides a negative vacuum for the workpiece fixing shaft 84, enabling the product to be polished 5 to be in limit cooperation with the workpiece fixing shaft 84.

[0027] As Figure 6 shown, in this embodiment, the grinding wheel assembly 35 includes a coarse grinding wheel 37 and a fine grinding wheel 38. The first drive motor 32 close to the product fixing module 2 is rotationally engaged with the coarse grinding wheel 37, and the other first drive motor 32 is rotationally engaged with the fine grinding wheel 38. Thus, it can be seen that the grinding wheel assembly 35 includes the coarse grinding wheel 37 and the fine grinding wheel 38. The coarse grinding wheel 37 performs rough polishing on the side surface of the product to be polished 5, and the fine grinding wheel 38 performs fine polishing on the side surface of the product to be polished 5. Both the coarse grinding wheel 37 and the fine grinding wheel 38 are driven by drive motors.

[0028] As Figure 2 shown, in this embodiment, a dust extraction device 10 is provided on the frame 1. The dust extraction device 10 includes a three-prong head. The three-prong head is respectively connected and cooperated with an external dust collector and a pair of grinding wheel covers 36 through plastic hoses. Thus, it can be seen that the three-prong head plays an intermediate connection role. The three heads of the three-prong head are respectively connected and cooperated with the external dust collector and a pair of grinding wheel covers 36. The external dust collector sucks away the fine impurities and dust generated during the polishing of the product side polishing module 3 and the product to be polished 5 through the three-prong head and the plastic hose, improving the cleanliness of the equipment.

[0029] As Figure 4 and Figure 5As shown, in this embodiment, a number of suction nozzle holes 85 are provided on the side surface of the workpiece fixing shaft 84. The workpiece fixing shaft 84 is suction-fitted with the product to be polished 5 through the vacuum suction assembly 83 and the number of suction nozzle holes 85. A chamfer 86 is provided at one end of the workpiece fixing shaft 84 away from the fixing shaft rotating seat 82, and the chamfer 86 cooperates with the product to be polished 5. Thus, by cooperating with the vacuum suction assembly 83, the workpiece fixing shaft 84 makes a negative vacuum on the number of suction nozzle holes 85, and can firmly limit and cooperate the product to be polished 5 on the workpiece fixing shaft 84. The suction nozzle holes 85 and the vacuum suction assembly 83 play a role in adsorbing and limiting the product to be polished 5.

[0030] As Figure 6 shown, in this embodiment, the movable ends of a pair of the first drive motors 32 are arranged face to face on the frame 1, and the product to be polished 5 is successively and sequentially frictionally engaged with the coarse grinding wheel 37 and the fine grinding wheel 38. Thus, after the side surface of the product to be polished 5 is first coarsely frictionally engaged with the coarse grinding wheel 37, the fine grinding wheel 38 then finely polishes the side surface of the product to be polished 5. At the same time, a pair of the first drive motors 32 are arranged face to face on the frame 1, which can reduce the moving distance of the product fixing module 2, and the product area that has been coarsely polished by the coarse grinding wheel 37 can be immediately finely polished by the fine grinding wheel 38, improving the working efficiency of product polishing.

[0031] In this embodiment, the working principle of the present utility model is as follows:

[0032] As Figures 1 to 7As shown, the operator sets the product 5 to be polished on the workpiece fixing shaft 84. The vacuum suction assembly 83 evacuates the inside of the workpiece fixing shaft 84 to firmly limit the product 5 to be polished on the workpiece fixing shaft 84. After starting the equipment, the U-axis servo motor 81 drives the workpiece fixing shaft 84 to rotate. The X-axis servo motor 21 and the Y-axis servo motor 24 respectively drive the product fixing module 2 to move towards the product side polishing module 3. The driving cylinder 33 drives the product side polishing module 3 to approach the product fixing module 2. The first driving motor 32 drives the grinding wheel assembly 35 to rotate. The product 5 to be polished is first roughly polished by the rough grinding wheel 37, and the side surface of the product 5 to be polished that has been roughly polished is finely polished by the fine grinding wheel 38. After completion, the driving cylinder 33 drives the product side polishing module 3 away from the product fixing module 2. The product fixing module 2 drives the product 5 to be polished to approach the product top surface polishing module 4. The second driving motor 41 drives the material receiving tray 43, and the material receiving tray 43 drives the polishing sandpaper 46 to move along the sandpaper guide assembly 45. The polishing sandpaper 46 moves to the top surface of the convex plate 44 and the product 5 to be polished for polishing. After polishing is completed, the X-axis servo motor 21 and the Y-axis servo motor 24 respectively drive the product fixing module 2 to return to the original position. The operator removes the polished product, and the cycle is repeated in sequence.

[0033] Although the embodiments of the present invention are described with actual solutions, they do not constitute a limitation to the meaning of the present invention. For those skilled in the art, modifications to its implementation solutions according to this specification and combinations with other solutions are obvious.
