[0016] The accompanying drawings in this specification are schematic diagrams used to illustrate the concept of this utility model, and schematically show the shapes of the various parts and their interrelationships. Please note that, in order to clearly show the structure of the components of the embodiments of this utility model, the drawings are not drawn to the same scale. The same reference numerals are used to indicate the same parts.
[0017] Example: A polishing device for processing metal castings includes a frame 1, a mounting frame 2 with a placement groove on the top fixed on the frame 1, a movable seat 3 slidably mounted on the top of the mounting frame 2, a first cylinder 4 embedded in the movable seat 3, a second cylinder 5 fixed on the right side of the top of the mounting frame 2, the piston rod of the second cylinder 5 fixed to the movable seat 3 via a vertical plate, a fixing frame 6 fixed to the piston rod of the first cylinder 4, a third cylinder 9 embedded on the back of the fixing frame 6, a sliding frame 7 slidably mounted inside the fixing frame 6, and the piston rod of the third cylinder 9 fixed to the sliding frame 7, a first motor 8 embedded at the bottom of the sliding frame 7, a polishing disc for polishing the square plate-shaped metal casting fixed to the output shaft of the first motor 8, a controller mounted on one set of legs of the frame 1, and fourth cylinders 10 embedded on both sides of the mounting frame 2, with an auxiliary conversion component for changing the surface of the square plate-shaped metal casting mounted on the piston rod of the fourth cylinder 10, the auxiliary conversion component including a mounting cylinder fixed to the piston rod of the fourth cylinder 10. The second motor 12 has a pressure plate 13 fixed to its output shaft. Each pressure plate 13 has a first support plate 16 and a second support plate 17 slidably arranged at its top and bottom. Each pressure plate 13 has a reinforcing shaft 18 mounted longitudinally. One end of the reinforcing shaft 18 is fixed to a flip plate 19. The flip plate 19 has symmetrically opened positioning grooves 20. The front of the first support plate 16 and the second support plate 17 each has a drive rod 21 with one end inserted into the positioning groove 20. The back of the pressure plate 13 is fixed to a third motor 25 whose output shaft end is fixed to the other end of the reinforcing shaft 18 via a back frame. The auxiliary conversion assembly also includes a support frame 22 that is slidably arranged in the mounting frame 2 and is in contact with the bottom of the second support plate 17. The bottom of the frame 1 has a fifth cylinder 23 with a piston rod fixed to the support frame 22 on both sides. The center of the top of the support frame 22 has a protruding plate integrally formed, and the height of the protruding plate is the same as the height of the first support plate 16 and the second support plate 17.
[0018] Specifically, this invention, by setting up an auxiliary conversion component and utilizing the second motor 12, can quickly flip the square metal casting to the other side after one side has been polished, thus automatically converting the surface to be polished. Furthermore, the design of the third motor 25, reinforcing shaft 18, flipping plate 19, positioning groove 20, and drive rod 21 forms a synchronous conversion structure for the positions of the first support plate 16 and the second support plate 17. This allows the square metal casting to simultaneously and quickly change the positions of the first and second support plates 16 and 17 after the face is changed, continuing to support the flipped first and second support plates 16 and 17. The design of the fifth cylinder 23 and support frame 22 forms an independent support structure. This dual support method ensures stable support for the square metal casting, facilitating comprehensive polishing of the square metal casting by the user. The entire conversion process is fully automated, improving the overall polishing efficiency of the device.
[0019] Multiple sets of anti-slip blocks 14 are fixed sequentially at the top and bottom of the pressure plate 13 along the front-to-back direction. Anti-slip channels 15 that slide with the anti-slip blocks 14 are provided on the side of the first support plate 16 and the second support plate 17 that are close to each other.
[0020] Specifically, by utilizing the sliding connection between the anti-shifting block 14 and the anti-shifting channel 15, the first support plate 16 and the second support plate 17 can be slidably limited, which improves the smoothness of the transition between the first support plate 16 and the second support plate 17. Furthermore, the two ends of the anti-shifting channel 15 are in an open state, which makes it convenient for the anti-shifting block 14 to move, and can simultaneously push away any impurities in the anti-shifting channel 15.
[0021] The support frame 22 has sliding side frames 24 fixed on both sides of the front and back, and the bottom end of the sliding side frame 24 is inserted into the frame body 1.
[0022] Specifically, the design of the sliding side frame 24 can limit the movement direction of the support frame 22 while providing synchronous sliding support, thereby effectively preventing the support frame 22 from tilting easily.
[0023] Auxiliary slides 11 are inserted on both sides of the mounting bracket 2, and one end of the auxiliary slide 11 is fixed to the mounting cylinder.
[0024] Specifically, the auxiliary slide 11 is designed to limit the sliding of the mounting cylinder, thereby providing auxiliary support for the second motor 12 inside, and then providing synchronous and stable support for the pressure plate 13 and its upper structure, so as to further stabilize the square metal casting.
[0025] Each pressure plate 13 has at least three sets of anti-slip blocks 14 at the top and bottom.
[0026] Specifically, the number of anti-slip blocks 14 at the top and bottom of each set of pressure plates 13 is limited in order to improve the overall stability of the first support plate 16 and the second support plate 17, thereby improving the support stability of the opposite plate-shaped metal casting.
[0027] In use: The user places the square metal casting in the center of the second support plate 17, with the bottom of the square metal casting contacting the top protrusion of the support frame 22. The user then activates the fourth cylinder 10 via the controller, which drives the pressure plate 13 inward, thus positioning the square metal casting. The user then activates the first cylinder 4, second cylinder 5, third cylinder 9, and first motor 8 via the controller, driving the polishing disc to rotate and changing its vertical and horizontal positions, thus polishing the top of the square metal casting. After polishing, the user pre-controls the polishing disc to move upward and reset, and activates the fifth cylinder 23 via the controller, causing the support frame 22 to move downward close to the frame 1. The user then activates the second motor 12 via the controller, driving the pressure plate 13 and the square metal casting above it to rotate together until the bottom of the square metal casting is rotated to the top. At this time, the second support plate 17 rotates synchronously from the bottom. Move to the top and activate the third motor 25 via the controller. The third motor 25, in conjunction with the reinforcing shaft 18, drives the flipping plate 19 to rotate synchronously. This, in conjunction with the positioning slot 20, allows for synchronous reverse rotation of the positions of the upper and lower sets of drive rods 21 until the second support plate 17 moves outward and the first support plate 16 moves inward and is positioned below the square metal casting. At this point, there will be a certain height difference between the first support plate 16 and the square metal casting. The user then controls the pressure plate 13 to move slightly, allowing the square metal casting to fall onto the first support plate 16. The pressure plate 13 is then controlled to reposition the square metal casting, and the support frame 22 is simultaneously reset. The support frame 22 supports both the square metal casting and the first support plate 16. The user can then use the polishing disc to continue polishing the flipped surface of the square metal casting. The entire conversion process is fully automated, improving the overall polishing efficiency of the device.
[0028] In summary, this polishing device for metal casting processing can automatically switch the surface to be polished by setting an auxiliary conversion component. After flipping, the support positions of the first support plate 16 and the second support plate 17 are changed simultaneously. In addition, with the addition of a set of independent support structures below, the dual support method can ensure the stable support of the plate-shaped metal casting, thereby facilitating the user to perform comprehensive polishing of the plate-shaped metal casting. The entire conversion process is fully automated, which improves the overall polishing efficiency of the device.
[0029] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the utility model in order to achieve the purpose of the utility model.
