DETAILED DESCRIPTION
[0018] The technical solutions in the embodiments will be described clearly and completely below in conjunction with the drawings in the embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of the present application.
[0019] As shown in Figure 1 , Figure 2 , Figure 3 The embodiment discloses a tensioning wheel polishing device, which comprises a lifting device 1, a table plate 2, a polishing device 3, a limiting assembly 4 and a supporting plate 5. The tensioning wheel 6 comprises an extension plate 61 extending horizontally and a positioning hole 62. The positioning hole 62 is a nut hole of a central shaft screw of the tensioning wheel 6. The lifting device 1 and the polishing device 3 are installed on the table plate 2. The lifting device 1 comprises a mounting plate 11, a driving device 12 and a movable frame 13. The mounting plate 11 is vertically fixedly installed on the table plate 2 through a fixed column. The driving device 12 is installed on the mounting plate 11. The movable frame 13 is slidingly installed on the mounting plate 11. The driving device 12 drives the movable frame 13 to slide. The driving device 12 is an electric telescopic device. The driving device 12 is installed on the back of the mounting plate 11. The movable frame 13 is installed on the front of the mounting plate 11 through a sliding rail. Part of the movable frame 13 penetrates through the mounting plate 11. The driving device 12 is connected with the movable frame 13 and can drive the movable frame 13 to slide up and down to approach or move away from the upper end face of the table plate 2.
[0020] A guide plate 14 is installed on the lower end face of the movable frame 13. The guide plate 14 movably installs a bottom plate 15. The movable frame 13 installs a guide rod 16. The guide rod 16 penetrates through the guide plate 14 and the movable frame 13. The lower end of the guide rod 16 is fixedly connected with the bottom plate 15. The upper end of the guide rod 16 extends out of the movable frame 13. The upper end of the guide rod 16 is provided with an end head 161. The guide rod 16 installs a second spring 162. The upper end of the second spring 162 abuts against the movable frame 13 and the end head 161. The bottom plate 15 can approach or move away from the movable frame 13. The upper end face of the bottom plate 15 and the lower end face of the movable frame 13 can clamp the tensioning wheel 6. The second spring 162 always makes the bottom plate 15 bear upward tension. The tensioning wheel 6 is put into the space between the bottom plate 15 and the lower end face of the movable frame 13 from the side of the bottom plate 15 away from the guide plate 14. The bottom plate 15 can be pulled down to provide a space for the tensioning wheel 6. The bottom plate 15 can be suitable for tensioning wheels 6 of different heights.
[0021] The support plate 5 is movably mounted on the base plate 2, and the support plate 5 can be close to or away from the base plate 2. The support plate 5 is located below the bottom plate 15, and the height of the support plate 5 can be adjusted by the lead screw. The upper end surface of the support plate 5 forms a limit for the downward movement of the bottom plate 15, which can limit the lowest position of the bottom plate 15, so that the degree of polishing can have a standard, and the height of the support plate 5 can be adjusted to facilitate the polishing of the extension plate 61 of the different specifications of the tensioning wheel 6 at different heights.
[0022] The bottom plate 15 is provided with a guide hole 151 penetrating through the upper end surface and the lower end surface of the bottom plate 15. The guide hole 151 is mounted with a movable block 17, and the movable block 17 can move along the guide hole 151. The first spring 152 is installed in the guide hole 151 to press the movable block 17 upward. After the movable block 17 is pressed downward, it can be reset. The lower end surface of the tensioning wheel 6 is provided with a positioning hole 62. The movable block 17 can be inserted into the positioning hole 62. When the tensioning wheel 6 is installed on the upper end surface of the bottom plate 15 from the side away from the guide plate 14, the tensioning wheel 6 will press the movable block 17 into the guide hole 151 until the movable block 17 is aligned with the positioning hole 62 and is inserted, thereby positioning the tensioning wheel 6 on the bottom plate 15.
[0023] More preferably, the upper end edge of the side of the bottom plate 15 away from the guide plate 14 is provided with a curved surface 153, which contacts and presses the edge of the lower end surface of the tensioning wheel 6, thereby guiding the installation of the tensioning wheel 6 between the bottom plate 15 and the lower end surface of the movable frame 13, making it easier to put in the tensioning wheel 6.
[0024] The polishing device 3 comprises a motor 31 and a grinding wheel 32 driven to rotate by the motor 31. The grinding wheel 32 is located on the upper end surface of the base plate 2, and the extension plate 61 is at least partially located above the grinding wheel 32. The upper end surface of the grinding wheel 32 is a polishing surface. The movable frame 13 moves up and down to make the extension plate 61 close to or away from the polishing surface. The extension plate 61 contacts the polishing surface to polish.
[0025] The limiting component 4 is mounted on the base plate 2, and the limiting component 4 comprises a limiting plate 41 located above the grinding wheel 32. The limiting plate 41 is provided with a limiting groove 411 communicating with the upper end surface and the lower end surface of the limiting plate 41. The limiting groove 411 is open toward the lifting device 1. The extension plate 61 can enter the limiting groove 411. When the tensioning wheel 6 is placed between the bottom plate 15 and the lower end surface of the movable frame 13, the extension plate 61 needs to be aligned with the limiting groove 411 manually, so that the extension plate 61 can enter the limiting groove 411 after the tensioning wheel 6 is lowered. The limiting groove 411 limits the extension plate 61 when the extension plate 61 contacts the grinding wheel 32 for polishing, preventing the extension plate 61 from being rotated by the grinding wheel 32 during polishing.
[0026] More preferably, the two side edges of the upper end of the limiting groove 411 are provided with inclined surfaces 412, the inclined surfaces 412 on the two sides of the limiting groove 411 can provide a guiding effect for the extension plate 61 to enter the limiting groove 411, so that the extension plate 61 will offset the extension plate 61 through the drop to the inclined surface 412 when the extension plate 61 is lowered, and the inclined surface 412 guides the extension plate 61 to the inside of the limiting groove 411.
[0027] The preferred embodiments of the present application are described above, the protection scope of the present application is not limited to the above-mentioned embodiments, any technical solutions falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary skilled in the art, some improvements and decorations without departing from the principles of the present application, these improvements and decorations shall also be considered as the protection scope of the present application.
