Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

In addition, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0027] In the description of the embodiments of the present invention, it should be noted that the terms "inside", "outside", "upper", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0028] like Figures 1 to 5 As shown, it includes a processing platform 3, the top surface of the processing platform 3 is provided with a mounting plate 2, the top surface of the mounting plate 2 is provided with a positioning component 1 for clamping and fixing the metal casting, the positioning component 1 is an axially symmetrical structure with respect to the mounting plate 2, and the interior of the processing platform 3 is provided with a rotating component 5 for adjusting the direction of the metal casting.

[0029] The positioning component 1 is automatically adjustable. When the positioning component 1 contacts the metal casting to be processed, the surface of the positioning component 1 will first fit the surface of the metal casting, and then the positioning component 1 will fix the metal casting. This design allows the device to actively adjust according to the shape of the metal casting when clamping the metal casting, thereby increasing the contact area between the device and the metal casting, making the clamping of the metal casting more stable and improving the processing quality of the metal casting.

[0030] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the positioning assembly 1 includes a mounting seat 106, the interior of the mounting seat 106 is evenly provided with clamping columns 103, and one end of the clamping column 103 passes through the surface of the mounting seat 106, one end of the clamping column 103 is fixed with a limit block 109, a return spring 108 is fixed between the limit block 109 and the inner wall of the mounting seat 106, a mesh plate 104 is provided inside the mounting seat 106, and the mesh plate 104 is movably connected to the mounting seat 106, and the mesh plate 104 passes through the top surface of the mounting seat 106, rubber rings 110 are evenly provided in the mesh plate 104, and the rubber ring 110 is movably connected to the clamping column 103, a fixing frame 107 is provided on the top surface of the mounting seat 106, a positioning motor 101 is provided on the top surface of the fixing frame 107, a positioning threaded rod 102 is provided at the output end of the positioning motor 101, and the positioning threaded rod 102 is threadedly connected to the mesh plate 104, and a connecting block 105 is provided on the bottom surface of the mounting seat 106.

[0031] In the positioning assembly 1, the mesh plate 104 is always sleeved on the surface of the clamping column 103. Under the action of the reset spring 108, one end of the clamping column 103 is exposed on the surface of the mounting seat 106. When the mounting seat 106 is close to the metal casting to be processed, the clamping column 103 shrinks toward the mounting seat 106 along the surface of the metal casting. When the contact area between the metal casting and the contact column reaches the maximum, the positioning motor 101 will drive the positioning threaded rod 102 to rotate, so that the mesh plate 104 moves downward in the mounting seat 106, and then the friction between the rubber ring 110 in the mesh plate 104 and the clamping column 103 will increase, thereby achieving the fixation of the clamping column 103.

[0032] like Figure 2 , Figure 3 and Figure 6 As shown, the rotating assembly 5 includes a fixed sleeve 503, a lifting cylinder 504 is provided at the bottom end of the fixed sleeve 503, a rotating motor 502 is provided in the fixed sleeve 503, and the rotating motor 502 is movably connected to the fixed sleeve 503, and the output end of the lifting cylinder 504 is fixedly connected to the rotating motor 502, and a support plate 501 is provided at the output end of the rotating motor 502, a lifting groove 8 is provided on the top surface of the mounting plate 2, and the lifting groove 8 runs through the mounting plate 2, and the support plate 501 is movably connected to the lifting groove 8, an adjusting groove 9 is provided on the top surface of the mounting plate 2, and the connecting block 105 is movably connected to the adjusting groove 9, an adjusting screw rod 6 is provided in the adjusting groove 9, and the adjusting screw rod 6 is threadedly connected to the connecting block 105, and an adjusting motor 7 is fixed to one end of the adjusting screw rod 6.

[0033] In the rotating assembly 5, the function of the support plate 501 is to place the metal casting. When the metal casting has completed a part of the processing, under the action of the adjusting motor 7 and the adjusting screw 6, the positioning assemblies 1 will separate from each other, and then the metal casting will fall on the support plate 501, and then the rotating motor 502 will drive the support plate 501 to rotate, so that the unprocessed surface of the metal casting can be processed, and the function of the lifting cylinder 504 is to adjust the height of the support plate 501, so that the support plate 501 can always be in stable contact with the metal casting to prevent the metal casting from rolling.

[0034] like Figures 1 to 6 As shown, a bracket 4 is arranged on the bottom array of the processing platform 3 , a controller 10 is arranged on the top surface of the processing platform 3 , and the controller 10 is electrically connected to the positioning motor 101 , the rotating motor 502 , and the adjusting motor 7 , respectively.

[0035] In summary: in the positioning assembly 1, the mesh plate 104 is always sleeved on the surface of the clamping column 103. Under the action of the reset spring 108, one end of the clamping column 103 is exposed on the surface of the mounting seat 106. When the mounting seat 106 is close to the metal casting to be processed, the clamping column 103 shrinks toward the mounting seat 106 along the surface of the metal casting. When the contact area between the metal casting and the contact column reaches the maximum, the positioning motor 101 will drive the positioning threaded rod 102 to rotate, so that the mesh plate 104 moves downward in the mounting seat 106, and then the friction between the rubber ring 110 in the mesh plate 104 and the clamping column 103 will increase, so that the clamping column 103 is fixed. In the rotating assembly 5, the function of the support plate 501 is to place the metal casting. After a part of the metal casting is processed, the adjusting motor 7 and the adjusting screw 6 are adjusted. Under the action, the positioning components 1 will separate from each other, and then the metal casting will fall on the support plate 501, and then the rotating motor 502 will drive the support plate 501 to rotate, so that the unprocessed surface of the metal casting can be processed, and the function of the lifting cylinder 504 is to adjust the height of the support plate 501, so that the support plate 501 can always be stably in contact with the metal casting to prevent the metal casting from rolling. The positioning component 1 is automatically adjustable. When the positioning component 1 contacts the metal casting to be processed, the surface of the positioning component 1 will first fit with the surface of the metal casting, and then the positioning component 1 will fix the metal casting. This design allows the device to actively adjust according to the shape of the metal casting when clamping the metal casting, thereby increasing the contact area between the device and the metal casting, making the clamping of the metal casting more stable, and improving the processing quality of the metal casting.
