[0043] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application: Specific embodiment 1:

[0045] like Figure 2 As shown, in this embodiment, the transverse direction is the length direction of the support beam 31.

[0046] refer to Figures 1 to 10 The present invention discloses a conductive tube outer cylindrical polishing device (hereinafter referred to as the polishing device) comprising a base 1, on which a movable working platform 2 and a transverse support frame 3 are longitudinally spaced apart. The movable working platform 2 is laterally slidably mounted on the base 1, and the transverse support frame 3 is laterally spaced apart. The support rollers 4 support a conductive tube 16 to be polished. The device also includes a drive mechanism 15. The drive mechanism 15 is configured to rotate the conductive tube 16 to be polished. The movable working platform 2 is provided with a polishing assembly comprising a polishing member and a movable mechanism for moving the polishing member to the conductive tube 16 to be polished.

[0047] In this embodiment, if Figure 2 、 4 As shown, the transverse support frame 3 includes a transversely extending support beam 31. Multiple sets of support frame reinforcement ribs 32 are spaced laterally along the longitudinal sides of the support beam 31 to enhance strength. Roller connection plates 41 are fixedly mounted on the upper ends of the support beams 31, corresponding to the positions of the support rollers 4. Two support rollers 4 are symmetrically positioned along the longitudinal sides of each roller connection plate 41, with the axes of the support rollers 4 extending transversely. This ensures that the axis of the conductive tube 16 to be cast, supported on the two support rollers 4, is aligned with the lower support beam 31, ensuring stability during rotation.

[0048] like Figure 1 、 2As shown in Figure 3, in this embodiment, the driving mechanism 15 includes a driving motor 151, the axis of the driving motor 151 extends horizontally, and a motor mounting bracket 23 is provided at the lower end of the driving motor 151, and the upper end of the motor mounting bracket 23 is at the same height as the support beam 31.

[0049] In this embodiment, the end of the conductive tube 16 to be thrown facing the drive motor 151 is connected to a connecting flange 17, and the end of the connecting flange 17 facing the drive motor 151 is provided with an extension portion. The driving mechanism 15 also includes a universal coupling 153 connected to the output end of the drive motor 151, and a rotating connecting tool 152 connecting the universal coupling 153 and the connecting flange 17.

[0050] Specifically, the rotary connection fixture 152 is in the form of a rotary sleeve. The side of the rotary sleeve facing the conductive tube 16 to be cast is provided with an inner hole adapted to fit the extension portion. A second flange 155 adapted to fit the connecting flange 17 is also mounted on this side. In actual use, the extension portion is first inserted into the inner hole of the rotary sleeve, and then the second flange 155 is connected to the connecting flange 17 to complete the assembly of the rotary connection fixture 152 and the conductive tube 16 to be cast. A first flange 154 is provided on the end of the rotary connection fixture 152 facing the universal coupling 153, and is connected to the universal coupling 153 via the first flange 154.

[0051] The drive motor 151 can be used to drive the universal joint 153 to rotate, thereby driving the rotational connection fixture 152 to rotate, thereby achieving rotation of the conductive tube 16 to be cast. The flexible connection of the universal joint 153 can eliminate the deviation between the axis of the output shaft of the drive motor 151 and the axis of the conductive tube 16 to be cast, ensuring that the drive motor 151 can drive the conductive tube 16 to be cast stably and reliably rotate, avoiding damage to parts. At the same time, the appropriate rotational connection fixture 152 is designed and selected according to the specifications of the conductive tube 16 to be cast, so that it can adapt to conductive tubes 16 of different diameters to be cast.

[0052] In this embodiment, if Figure 1 、 2 As shown in Figures 4 and 5, two transverse guide rails 18 are provided at longitudinal intervals at positions corresponding to the mobile work platform 2 on the base 1. The lower end of the mobile work platform 2 is slidably provided on the two transverse guide rails 18 in a transverse direction. Specifically, a longitudinal rotation shaft 19 is provided below the mobile work platform 2. Two longitudinal rotation shafts 19 are provided at transverse intervals. Two first bearing seats 20 are provided at longitudinal intervals at the lower end of the mobile work platform 2, corresponding to the position of each longitudinal rotation shaft 19. The longitudinal rotation shaft 19 is rotatably engaged with the corresponding first bearing seat 20 via a first bearing 21, thereby enabling the longitudinal rotation shaft 19 to be rotatably mounted on the lower end of the mobile work platform 2.

[0053] A movable roller 22 is mounted at each end of the longitudinal rotation axis 19, corresponding to the positions of the two transverse guide rails 18. The movable roller 22 is rollingly supported on the corresponding transverse guide rail 18. Specifically, the inner diameter of the movable roller 22 is adapted to the longitudinal rotation axis 19, and the outer diameter is longitudinally divided into a large diameter section and a small diameter section. The large diameter sections of the two movable rollers 22 are arranged relative to each other, and the small diameter sections are rollingly set on the corresponding transverse guide rail 18. The stepped surfaces of the large diameter section and the small diameter section abut against the inner side surface of the transverse guide rail 18. On the one hand, the movable roller 22 can realize the transverse movement of the movable working platform 2, and on the other hand, the stepped surface can guide the movement of the movable working platform 2 to avoid deviation and ensure the polishing quality.

[0054] In this embodiment, if Figure 10 As shown, a vertical motor mounting plate 302 is provided on the upper end surface of the mobile work platform 2 near one of the longitudinal rotating shafts 19. A motion motor 29 is fixedly mounted on one side of the upper portion of the motor mounting plate 302, and a driving sprocket 30 is correspondingly provided on the other side. The motion motor 29 drives the driving sprocket 30 to rotate. A driven sprocket 301 is fixedly mounted on the longitudinal rotating shaft 19. A drive chain 33 is wound around the driven sprocket 301 and the driving sprocket 30. In this way, the motion motor 29 can drive the driven sprocket 301 to rotate, thereby driving the longitudinal rotating shaft 19 to rotate, driving the moving roller 22 thereon to slide on the transverse guide rail 18, thereby achieving transverse sliding of the mobile work platform 2.

[0055] In this embodiment, preferably, the polishing assembly includes a mounting plate 5 spaced apart above the mobile working platform 2, the moving mechanism is used to connect the mounting plate 5 and the mobile working platform 2, and an active polishing wheel 6 and a driven polishing wheel 7 are longitudinally spaced apart on the mounting plate 5, and the polishing part includes a polishing sandpaper belt 8 wound around the active polishing wheel 6 and the driven polishing wheel 7.

[0056] Specifically, such as Figure 4 、 8As shown in Figures 9 and 9, a polishing motor 11, an active drive wheel 9, and a driven drive wheel 10 are mounted on the side of the mounting plate 5 facing away from the active polishing wheel 6. The active drive wheel 9 is mounted on the output end of the active drive wheel 9, and the driven drive wheel 10 is coaxially arranged with the active polishing wheel 6. A drive belt 110 is wound around the driven drive wheel 10 and the active drive wheel 9. A second bearing seat 26 is provided at a position on the mounting plate 5 corresponding to the driven drive wheel 10. The driven drive wheel 10 is rotatably mounted in the second bearing seat 26 via an active polishing shaft 112. The active polishing wheel 6 is fixedly mounted on the side of the active polishing shaft 112 facing away from the driven drive wheel 10. A mounting sleeve 111 is sleeved around the outer periphery of the active polishing shaft 112, and the mounting sleeve 111 is fixedly mounted on the mounting plate 5. The driven polishing wheel 7 is rotatably mounted on the mounting plate 5 via a driven polishing shaft 113. In this way, the polishing motor 11 can drive the active drive wheel 9 to rotate, thereby driving the driven drive wheel 10 to rotate, thereby realizing the rotation of the active polishing wheel 6 and driving the polishing cloth belt 8 to polish. Preferably, in this embodiment, the moving mechanism includes a vertical mounting frame and a lifting mechanism arranged on the mobile working platform 2 along the longitudinal direction. The upper end of the vertical mounting frame is hingedly connected to the lower end surface of the mounting plate 5, and the two ends of the lifting mechanism are respectively hingedly connected to the lower end surface of the mounting plate 5 and the mobile working platform 2.

[0057] Specifically, the vertical mounting frame is arranged between the transverse support frame 3 and the lifting mechanism. The vertical mounting frame includes a channel steel support frame 121 fixedly mounted on the mobile working platform 2. The upper end of the channel steel support frame 121 is provided with a transverse section extending toward the transverse support frame 3. A vertical support plate 122 is provided at the upper end of the transverse section. A hinge seat 24 is provided at the position of the mounting plate 5 corresponding to the support plate 122. The mounting plate 5 is hingedly connected to the hinge seat 24 through a hinge shaft 25.

[0058] In this embodiment, the lifting mechanism is a hydraulic cylinder 131. A hydraulic station 132 is located on the side of the mobile work platform 2 facing away from the hydraulic cylinder 131. Two hydraulic connection pipes 133 connect the hydraulic cylinder 131 and the hydraulic station 132, thereby enabling the telescopic movement of the hydraulic cylinder 131. An articulated seat 24 is located at the lower end of the mounting plate 5, corresponding to the upper end of the hydraulic cylinder 131. The upper end of the hydraulic cylinder 131 is hingedly connected to this articulated seat 24 via an articulated shaft 25. Similarly, an articulated seat 24 is located at the upper end of the mobile work platform 2, corresponding to the lower end of the hydraulic cylinder 131. The lower end of the hydraulic cylinder 131 is articulatedly connected to this articulated seat 24 via an articulated shaft 25.

[0059] In this way, the mounting plate 5 can be swung around the upper end of the vertical mounting frame by lifting and lowering the lifting hydraulic cylinder 131, thereby driving the active polishing wheel 6 to approach or move away from the conductive tube 16 to be polished, making it convenient to adjust the position of the active polishing wheel 6 and the conductive tube 16 to be polished.

[0060] Preferably, Figure 5 、 6 As shown in Figures 7 and 9, in this embodiment, a protective plate 35 is further provided on the outside of the active polishing wheel 6 and the driven polishing wheel 7, and a tensioning mechanism 14 is further provided between the active polishing wheel 6 and the driven polishing wheel 7. The tensioning mechanism 14 includes a tensioning plate 141, which is fixedly provided on the side of the mounting plate 5 at a position between the active polishing wheel 6 and the driven polishing wheel 7. A tensioning cylinder 142 is provided on the tensioning plate 141. Specifically, the tensioning cylinder 142 is located between the driven polishing wheel 7 and the active polishing wheel 6, and the tensioning cylinder 142 is fixedly installed on the tensioning plate 141 through a connecting bracket 1413.

[0061] A compressed air pipe 1412 is provided at each end of the tensioning cylinder 142, thereby enabling the tensioning cylinder 142 to be extended and retracted. The retractable end of the tensioning cylinder 142 is arranged toward the driven polishing wheel 7, and a tensioning frame 143 is provided at the retractable end of the tensioning cylinder 142. The driven polishing wheel 7 is rotatably mounted on the tensioning frame 143 via the driven polishing shaft 113.

[0062] Specifically, in this embodiment, the tensioning frame 143 includes a transverse extension plate 145 fixedly mounted on the telescopic end of the tensioning cylinder 142, and a longitudinal extension plate 144 is respectively arranged on both sides of the transverse extension plate 145. The longitudinal extension plate 144 extends toward the driven polishing shaft 113, and the spacing between the two longitudinal extension plates 144 is adapted to the transverse length of the driven polishing wheel 7. The driven polishing wheel 7 is clamped between the two longitudinal extension plates 144.

[0063] A snap-fitting notch 146 adapted to the driven polishing shaft 113 is provided on the side of the longitudinal extension plate 144 facing the driven polishing wheel 7. The driven polishing shaft 113 is snapped into the snap-fitting notch 146, and the driven polishing wheel 7 is rotatably mounted on the driven polishing shaft 113 via the driven bearing 114. The extension and contraction direction of the tensioning cylinder 142 coincides with the line connecting the active polishing shaft 112 and the driven polishing shaft 113. In this way, the tensioning cylinder 142 can drive the tensioning frame 143 to move, and the tensioning frame 143 can then drive the driven polishing shaft 113 to move, thereby adjusting the spacing between the active polishing wheel 6 and the driven polishing wheel 7 and the tightness of the polishing belt 8. This ensures that the polishing belt 8 is always tensioned during polishing, thereby ensuring polishing quality, and facilitates replacement of the polishing belt 8.

[0064] In this embodiment, preferably, an adjustment mechanism 147 is further provided on the longitudinal extension plate 144, and the adjustment mechanism 147 includes an adjusting nut 148 provided on the longitudinal extension plate 144, and an adjusting screw 149 is connected to the internal thread of the adjusting nut 148, and the adjusting screw 149 abuts against the circumferential surface of the driven polishing shaft 113 toward one end of the driven polishing shaft 113. In this way, by adjusting the relative position of the adjusting screw 149 in the adjusting nut 148, the driven polishing shaft 113 can be driven to move by the adjusting screw 149, and the tightness of the polishing sandpaper belt 8 can be further adjusted to ensure that the polishing sandpaper belt 8 is always taut during polishing, thereby improving the accuracy of the tightness adjustment.

[0065] Preferably, in this embodiment, the adjusting nut 148 is rotatably mounted on the longitudinal extension plate 144. Specifically, an arcuate groove (not shown) is provided at a position on the longitudinal extension plate 144 corresponding to the adjusting nut 148. The outer periphery of the adjusting nut 148 is cylindrical and matches the arcuate groove. The adjusting nut 148 is rotatably mounted in the arcuate groove via a bearing. Furthermore, an arcuate surface 1410 is provided at one end of the adjusting screw 149 facing the driven polishing shaft 113, matching the circumference of the driven polishing shaft 113. The arcuate surface 1410 can increase the contact area between the adjusting screw 149 and the driven polishing shaft 113, ensuring reliable contact and improving stability. At the same time, the arcuate surface 1410 cooperates with the circumference of the driven polishing shaft 113 to prevent the adjusting screw 149 from rotating, thereby achieving linear movement of the adjusting screw 149 under the rotation of the adjusting nut 148.

[0066] Of course, in other embodiments, the adjusting nut 148 can also be directly fixed on the longitudinal mounting plate 144. In this case, the end surface of the adjusting screw 149 facing the driven polishing shaft 113 is flat, and its position can be adjusted by rotating the adjusting screw 149. Figure 2 、 4 As shown in Figures 9 and 9, a vertical plate is provided on each longitudinal side of the base 1, so that the interior of the base 1 forms a water receiving tray 101. A water tank 28 and a control console 27 are also provided on the mobile working platform 2, and the water tank 28 is provided at the lower end of the hydraulic station 132 to improve space utilization. During the actual polishing operation, it is necessary to spray water on the polishing part, so a water supply pump (not shown in the figure) is connected to the water tank 28, and a water supply pipe (not shown in the figure) is connected to the water supply pump. The other end of the water supply pipe extends to the mounting plate 5 and is arranged toward the part to be polished. In this way, water can be sprayed in real time during polishing to cool down, reduce dust, be beneficial to environmental protection, and avoid affecting the polishing quality.

[0067] At the same time, the water receiving tray 101 can be used to receive the flowing water. A water pump (not shown in the figure) is also provided on the water receiving tray 101. The water pump is connected to the water tank 28 through a water pipe, and is used to recycle the water flowing to the water receiving tray 101 into the water tank 28, thereby realizing the recycling of water resources.

[0068] The use process of the polishing equipment of the present invention is:

[0069] First, the conductive tube 16 to be thrown is mounted on the support roller 4 at the upper end of the transverse support frame 3, and the end of the conductive tube 16 to be thrown with the connecting flange 17 is fixed toward the drive motor 151. An appropriate rotating connecting tool 152 is selected to connect the universal coupling 153 and the connecting flange 17. The rotating connecting tool 152 and the drive motor 151 are connected through the universal coupling 153, so that the drive motor 151 is used to drive the conductive tube 16 to rotate.

[0070] Contract the tensioning cylinder 142, replace the appropriate polishing abrasive belt 8, and then extend the tensioning cylinder 142 so that the polishing abrasive belt 8 is tensioned on the driven polishing wheel 7 and the active polishing wheel 6. At the same time, use the adjusting bolt 149 to adjust the position of the driven polishing shaft 113 and the tension of the polishing abrasive belt 8.

[0071] Start the lifting hydraulic cylinder 131 to drive the active polishing wheel 6 to flip toward the conductive tube 16 to be polished until the polishing sandpaper belt 8 contacts the outer periphery of the conductive tube 16 to be polished, start the polishing motor 11, and the polishing sandpaper belt 8 performs the polishing operation. At the same time, start the motion motor 29, and use the active sprocket 30 to drive the driven sprocket 301 to rotate, thereby driving the mobile working platform 2 to move horizontally to achieve the overall polishing operation of the conductive tube 16 to be polished.

[0072] In summary, the polishing equipment of the present invention utilizes the transverse support frame 3 and the support roller 4 to stably support the conductive tube 16 to be polished. The driving mechanism 15 combined with the support roller 4 can drive the conductive tube 16 to be polished to rotate. The polishing assembly can be driven by its moving mechanism to move the polishing piece to the surface of the conductive tube 16 to be polished for polishing. At the same time, the mobile working platform 2 can drive the polishing assembly to move horizontally, and then the polishing piece can be used to complete the polishing operation of the entire conductive tube 16 to be polished. On the one hand, the labor intensity of the workers is reduced, and on the other hand, the work quality can be guaranteed and the work efficiency can be improved. At the same time, the conductive tube 16 to be polished is supported as a whole on the transverse support frame 3 and only rotates, without the need for horizontal movement, which can improve the safety and reliability of the operation.
