This method is inefficient and requires a certain level of experience and skill from the operators. Furthermore, for some large die-cast parts, manual operation often makes it difficult to accurately position and handle them; there are also certain safety hazards during the processing.

[0022] The following will refer to the appendix in the embodiments of this utility model. Figure 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] Example:
[0024] like Figures 1 to 4 As shown, this utility model discloses an aluminum die-casting grinding equipment, including a workbench 1, on which a mounting base 21 is provided and an electric grinder located on one side of the mounting base 21. At the same time, the workbench 1 is provided with a spacing adjustment mechanism for moving the electric grinder closer to or further away from the mounting base 21.
[0025] The mounting base 21 is provided with a pressure plate 22 and a positioning post 23. The pressure plate 22 is detachably mounted on the upper end of the mounting base 21, and the positioning post 23 is sleeved on the mounting base 21 and slides up and down below the pressure plate 22. In this structure, the workbench 1 is provided with a height adjustment mechanism for adjusting the distance between the positioning post 23 and the pressure plate 22, a drive mechanism for driving the positioning post 23 to rotate, and a synchronous rotation mechanism for making the positioning post 23 and the pressure plate 22 rotate synchronously.
[0026] The detachable arrangement between the pressure plate 22 and the mounting base 21 is as follows: a sleeve hole 231 is provided in the middle of the positioning pile 23, which passes through the upper and lower ends of the positioning pile 23. The positioning pile 23 is sleeved on the outside of the mounting base 21 through the sleeve hole 231. At the same time, a threaded hole 211 is provided at the upper end of the mounting base 21. Correspondingly, a screw 221 for installation with the threaded hole 211 is provided at the lower end of the pressure plate 22.
[0027] The height adjustment mechanism specifically includes a cylinder 24 fixedly mounted on the workbench 1. The cylinder 24 includes a piston rod 241, which extends upward and is used to connect with the lower end of the positioning post 23.
[0028] The drive mechanism specifically includes a gear ring 33, a gear 32, and a first motor 31. The gear ring 33 is fixedly mounted on the outer wall of the positioning post 23, the first motor 31 is fixedly mounted on the worktable 1 and its output end is fixedly connected to the gear 32, and the gear 32 is meshed with the gear ring 33.
[0029] Furthermore, the lower end of the mounting base 21 is rotatably connected to the worktable 1. The synchronous rotation mechanism includes a slider 212 fixedly mounted on the outer wall of the mounting base 21. In this structure, a vertical slide 232 is provided on the inner wall of the sleeve hole 231 corresponding to the slider 212. The vertical slide 232 and the slider 212 are matched to prevent the mounting base 21 from rotating relative to the positioning post 23. At the same time, the positioning post 23 can slide up and down on the outer wall of the mounting base 21. In addition, an annular rotation groove 233 is provided on the lower end face of the positioning post 23. An annular limiting groove 234 is provided on the upper end of the rotation groove 233. Correspondingly, the piston rod 241 is slidably mounted in the rotation groove 233 and a first limiting block 242 is fixedly mounted on its upper end. The first limiting block 242 is slidably mounted in the limiting groove 234.
[0030] The electric grinder includes a mounting frame 41, a drive roller 43, a driven roller 44, a second motor 42, and a grinding belt 45. The drive roller 43 and the driven roller 44 are rotatably mounted on the mounting frame 41. The second motor 42 is fixedly mounted on the mounting frame 41 and its output end is connected to the drive roller 43. The grinding belt 45 is sleeved on the drive roller 43 and the driven roller 44. In this structure, the spacing adjustment mechanism is used to move the mounting frame 41 closer to or further away from the mounting base 21.
[0031] The spacing adjustment mechanism specifically includes a second limiting block 48, a lead screw 47, and a third motor 46. The second limiting block 48 is fixedly mounted on the lower end of the mounting bracket 41 and slidably mounted on the worktable 1. The third motor 46 is fixedly mounted on the worktable 1. The lead screw 47 is rotatably mounted on the worktable 1 and fixedly connected to the output end of the third motor 46. Furthermore, the second limiting block 48 is sleeved around the lead screw 47 and connected to the lead screw 47 via a threaded connection.
[0032] The working principle of the above structure is as follows: When the aluminum die-casting needs to be fixed, the aluminum die-casting can be placed on the positioning post 23 first, and then the pressure plate 22 is threadedly connected to the mounting base 21. At this time, because the gear 32 locks the gear ring 33, the mounting base 21 will not rotate when the screw 221 rotates, so the pressure plate 22 can be installed normally. After installation, the positioning post 23 is lifted upward by the cylinder 24, and the aluminum die-casting can be clamped between the pressure plate 22 and the positioning post 23. After the aluminum die-casting is completed, the third electric drive is activated. After the electric grinder 46 is brought close to the surface of the aluminum die casting, the second motor 42 drives the grinding belt 45 to grind the surface of the aluminum die casting. During the grinding process, the first motor 31 can drive the gear 32 to rotate the gear ring 33, so that the aluminum die casting is being ground and rotating at the same time, which is conducive to achieving rapid grinding of the entire circumference of the weld line. After the grinding is completed, the piston rod 241 retracts, causing the positioning post 23 to move downward. At this time, the pressure plate 22 can be removed from the mounting base 21 to replace the aluminum die casting.
[0033] It should also be noted that the terms used in this utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
