Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1-6, the present utility model provides a technical solution: a fixing tooling for special-shaped metal castings, including a fixing mechanism 1 and a fixing motor 103 installed on one side inside the fixing mechanism 1. A supporting mechanism 2 is arranged at the central position of the bottom of the fixing mechanism 1, and a supporting sliding plate 210 is arranged at the top of the supporting mechanism 2. The fixing mechanism 1 includes a fixing workbench 101, and supporting legs 102 are fixedly installed around the bottom of the fixing workbench 101. The fixing motor 103 is fixedly installed on one side inside the fixing workbench 101. Among them, the output end of the fixing motor 103 is fixedly connected with a fixing gear 104, and a fixing toothed ring 105 is meshed and connected to one side of the fixing gear 104. Among them, a rotating disk 106 is fixedly installed at the top of the fixing toothed ring 105, and the fixing toothed ring 105 is rotatably connected with the fixing workbench 101. Rotating chutes 107 are opened around the inside of the rotating disk 106, and sliding sleeves 108 are arranged inside the rotating chutes 107. The top and bottom of the sliding sleeve 108 are rotatably connected with sleeve rotating shafts 109, and the sleeve rotating shafts 109 are rotatably connected with the rotating disk 106 through the rotating chutes 107. A rotating arm 110 is slidably connected inside the sliding sleeve 108. One end of the rotating arm 110 is fixedly installed with a rotating shaft 111, and the rotating shaft 111 is rotatably connected with the fixing workbench 101. An expansion chute 112 is opened at the end of the rotating arm 110 away from the rotating shaft 111. An expansion spring 113 is fixedly installed inside the expansion chute 112. The end of the expansion spring 113 is fixedly installed with a connecting block 114, and a fixing bracket 115 is fixedly installed at the end of the connecting block 114 away from the expansion spring 113. The connecting block 114 is slidably connected with the expansion chute 112 through the expansion spring 113. A fixing rotating block 116 is rotatably connected inside the fixing bracket 115.

At the same time, under the action of the sleeve rotating shaft 109, the sliding sleeve 108 can rotate inside the rotating chute 107, so that the surrounding rotating arms 110 rotate simultaneously, and can initially clamp and fix the special-shaped metal casting. By loosening the fixing bolt 117, when the rotating arms 110 approach each other, the fixing rotating block 116 can rotate, so as to fit the surface of the special-shaped metal casting. At the same time, using the elastic force of the expansion spring 113, the connecting block 114 drives the fixing bracket 115 to telescopically move inside the expansion chute 112, and can telescopically move according to the surface of the special-shaped metal casting, so that the fixing rotating block 116 fits the surface of the special-shaped metal casting more closely.It can achieve stable clamping of special-shaped metal castings, facilitating stable processing of metal castings.

[0031] The support mechanism 2 includes a support sleeve 201, which is fixedly installed at the central position of the bottom of the fixed workbench 101.

Support sliding rods 209 are fixedly installed around the top of the support thread bracket 207. A support sliding plate 210 is fixedly installed at the top of the support sliding rods 209. By driving the support screw rod 206 to rotate with the support motor 205, while the support thread bracket 207 drives the support sliding sleeves 208 to slide on the outer side of the support fixing rods 203, the support sliding rods 209 drive the support sliding plate 210 to move up and down, enabling the lifting adjustment of the special-shaped metal casting, moving the middle position of the special-shaped metal casting to the fixed rotating block 116, thereby clamping and fixing the middle position of the special-shaped metal casting and improving the clamping stability of the special-shaped metal casting.

[0032] Working principle: Before using this fixture for fixing special-shaped metal castings, it is necessary to first check the overall condition of the device to ensure that it can work properly. According to Figure 1 - Figure 6As shown in the figure, first, place the metal casting on the support sliding plate 210, start the support motor 205 to drive the support threaded rod 206 to rotate, so that the support threaded bracket 207 drives the support sliding sleeve 208 to slide outside the support fixed rod 203, and at the same time, the support sliding rod 209 drives the support sliding plate 210 to move up and down, which can adjust the lifting of the special-shaped metal casting, move the middle position of the special-shaped metal casting to the fixed rotating block 116, so as to clamp and fix the middle position of the special-shaped metal casting, improve the clamping stability of the special-shaped metal casting. Secondly, use the fixed motor 103 to drive the fixed gear 104 to rotate. Utilizing the meshing connection between the fixed gear 104 and the fixed gear ring 105, the fixed gear ring 105 drives the rotating disc 106 to rotate. Under the action of the rotating shaft 111, the rotating arm 110 can slide inside the sliding sleeve 108 while rotating. At the same time, under the action of the sleeve rotating shaft 109, the sliding sleeve 108 can rotate inside the rotating chute 107, so that the surrounding rotating arms 110 rotate simultaneously, which can initially clamp and fix the special-shaped metal casting. Finally, when the rotating arms 110 are brought closer to each other by loosening the fixing bolts 117, the fixed rotating block 116 can be rotated, so as to fit the surface of the special-shaped metal casting. At the same time, under the elastic force of the telescopic spring 113, the connecting block 114 drives the fixed bracket 115 to telescopically move inside the telescopic chute 112, which can telescopically move according to the surface of the special-shaped metal casting, so that the fixed rotating block 116 fits the surface of the special-shaped metal casting more closely, and the clamping stability of the special-shaped metal casting can be realized, which is convenient for the stable processing of the metal casting.
