The existing polishing method generally uses a drive motor to drive the sandpaper to polish the outer surface of the bow-shaped head. Since the bow-shaped head is relatively large, the sandpaper needs to be replaced after polishing one or more bow-shaped heads to ensure the efficiency of polishing. Based on this, the present invention proposes a bow-shaped head polishing device. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figures 1-3 In this embodiment of the utility model, a polishing and grinding device for an arc-shaped end cap includes a vertical rod 1, an axially movable rod 2 connected to the outer wall of the vertical rod 1 via a cylinder, an end cap body 3 disposed below the axially movable rod 2, and a transmission mechanism 4 disposed on the axially movable rod 2; the transmission mechanism 4 includes a grinding unit and a limiting unit; the grinding unit is used to grind and polish the upper surface of the end cap body 3; the limiting unit is used to quickly install and replace the sandpaper 402.
[0016] The polishing unit includes a drive motor 401, sandpaper 402, a rotating wheel 403, a connecting rod 404, and a fixing rod 405. The drive motor 401 is installed on the inner side of the end of the axially movable rod 2 and provides power for the transmission of the annular sandpaper 402. The sandpaper 402 is sleeved on the output end of the drive motor 401 and is used to polish the upper surface of the end cap body 3. The rotating wheel 403 is rotatably connected to the shaft end of the connecting rod 404 and provides support for the inner side of the other end of the annular sandpaper 402. The connecting rod 404 is vertically slidably installed on the outer wall of the fixing rod 405 and is used to synchronously drive the rotating wheel 403 to move vertically. The fixing rod 405 is fixed to the outer wall of the axially movable rod 2 and provides guidance for the vertical movement of the connecting rod 404.
[0017] The limiting unit includes a positioning rod 406, a spring 407, a guide groove 408, and a guide block 409. The positioning rod 406 is fixed to the bottom end of the fixed rod 405 and extends into the interior of the connecting rod 404. The positioning rod 406 is used to guide the vertical movement of the connecting rod 404. The two ends of the spring 407 are respectively engaged with the inner wall of the connecting rod 404 and the bottom end of the fixed rod 405. The spring 407 is used to provide a downward pressing force for the connecting rod 404 at all times. The guide groove 408 is opened on the outer wall of the fixed rod 405. The guide groove 408 is used to guide the movement of the guide block 409. The guide block 409 is fixed to the outer wall of the connecting rod 404 and extends into the inner side of the guide groove 408. The guide block 409 is used to limit the vertical movement of the connecting rod 404.
[0018] In this embodiment: It should be noted that the end cap body 3 is generally installed on the top of a rotating disk with a motor before grinding and polishing, and the motor drives the rotating disk and the end cap body 3 to rotate.
[0019] By activating the cylinder inside the upright 1, the positioning seat, which is slidably connected to the outer wall of the upright 1, is moved to the required position. Then, the positioning seat pushes the axial movable rod 2 to move axially, causing the drive motor 401 and the sandpaper 402 at the end of the axial movable rod 2 to move. The sandpaper 402 is moved to the top of the end cap body 3 and fits against the upper surface of the end cap body 3. Then, the drive motor 401 and the rotating disk can be activated to make the end cap body 3 rotate. The operation of the drive motor 401 will synchronously drive the sandpaper 402 to drive, and the driven sandpaper 402 will polish the upper surface of the rotating end cap body 3. When the sandpaper 402 needs to be replaced after polishing, the connecting rod 404 is rotated. The rotating connecting rod 404 synchronously drives the guide block 409 to rotate 90 degrees circumferentially. The guide block 409, which has rotated 90 degrees, will move along the horizontal sliding groove of the guide groove 408 to the end of the vertical sliding groove of the guide groove 408. At this time, the connecting rod 404 can be pushed upward, so that the connecting rod 404 moves vertically along the outer wall of the positioning rod 406 and the fixing rod 405. The vertically moving connecting rod 404 will apply the compressive force to the spring 407. The connecting rod 404 will also synchronously drive the rotating wheel 403 to move vertically. The moving rotating wheel 403 no longer provides support for one end of the sandpaper 402, so the sandpaper 402 can be quickly removed, which facilitates the installation and replacement of the sandpaper 402 and further improves work efficiency.
[0020] Please refer to this carefully. Figures 1-3The outer wall of the guide block 409 matches the inner side of the guide groove 408. The outer wall of the guide groove 408 is generally in the shape of a "C". The inner wall of the connecting rod 404 is formed with a groove for the vertical movement of the outer wall of the fixed rod 405. The inner wall of the connecting rod 404 is formed with a movable groove for the positioning rod 406 to enter. The outer wall of the connecting rod 404 is generally in the shape of an "L". The lateral end of the connecting rod 404 is rotatably connected to the outer wall of the rotating wheel 403. The inner wall of the upright rod 1 is formed with a groove for the vertical movement of the axially movable rod 2. A positioning seat for the axial movement of the axially movable rod 2 is provided at the connection between the axially movable rod 2 and the upright rod 1.
[0021] In this embodiment, this structure provides a C-shaped moving thrust to the connecting rod 404, causing the guide block 409 to engage in the transverse sliding groove above the guide groove 408, thus fixing the height of the rotating wheel 403. This facilitates the installation and connection of the sandpaper 402, further improving work efficiency.
[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
