DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 4The utility model provides an aluminum alloy casting finishing device, including a supporting shell 1, a supporting frame 2 is fixedly installed on the back of the supporting shell 1, a downward pressing positioning component is installed on the supporting frame 2, a fixing groove 3 is opened on the top of the supporting shell 1, and a receiving plate 4 is rotatably connected to the inner cavity of the fixing groove 3, and the downward pressing positioning component includes a lifting cylinder 11 fixedly installed on the top of the supporting frame 2, the telescopic end of the lifting cylinder 11 penetrates the supporting frame 2 and extends to the outside of the supporting frame 2, the telescopic end of the lifting cylinder 11 is rotatably connected to a connecting shell 12, the inner cavity of the connecting shell 12 is slidably connected to a connecting block 13, the bottom of the connecting block 13 penetrates the connecting shell 12 and extends to the outside of the connecting shell 12, and the bottom of the connecting block 13 is fixedly connected to a positioning block 14.

[0023] By setting the downward positioning component, when the aluminum alloy casting needs to be fine-processed, the user can place the aluminum alloy casting on the top of the receiving plate 4, and then open the lifting cylinder 11 through the external controller. After the lifting cylinder 11 is connected to the external air source, its telescopic end will drive the positioning block 14 to move downward through the connecting shell 12 and the connecting block 13, and press the aluminum alloy casting to the top of the receiving plate 4 to position and fix it.

[0024] Preferably, several groups of compression springs 15 are fixedly installed on the top of the connecting block 13, and the top of the compression spring 15 is fixedly connected to the inner wall of the connecting shell 12. Two groups of anti-slip pads 20 are arranged between the receiving plate 4 and the positioning block 14, one group of anti-slip pads 20 is installed at the bottom of the positioning block 14, and the other group of anti-slip pads 20 is installed at the top of the receiving plate 4.

[0025] By setting the compression spring 15, when the positioning block 14 is pressed against the surface of the aluminum alloy casting, the reaction force acting on it will squeeze the compression spring 15 through the connecting block 13, thereby playing a buffering role for the positioning block 14 to prevent it from directly applying force to the surface of the aluminum alloy casting to damage its appearance. By setting the anti-skid pad 20, the friction between the positioning block 14 and the receiving plate 4 and the aluminum alloy casting can be increased to prevent it from slipping when pressed and positioned.

[0026] Among them, a limiting component is also arranged between the inner wall of the connecting shell 12 and the surface of the connecting block 13, and the limiting component includes a limiting rod 16 fixedly installed on both sides of the inner cavity of the connecting shell 12, and a limiting groove 17 adapted to the limiting rod 16 is opened on the surface of the connecting block 13, and the inner wall of the limiting groove 17 is slidably connected to the surface of the limiting rod 16.

[0027] The setting of the limiting assembly can limit the connection block 13, so that it can rotate synchronously with the connection shell 12, so as to prevent the connection block 13 from rotating while the connection shell 12 is stationary, thereby preventing the compression spring 15 from being twisted. When the connection block 13 moves, it will drive the limiting groove 17 on its surface to slide on the surface of the limiting rod 16.

[0028] It is worth mentioning that the receiving plate 4 is rotatably connected to the inner cavity of the fixed groove 3 through a rotating assembly. The rotating assembly includes a rotating ring 18 fixedly mounted on the surface of the receiving plate 4.

[0029] By setting the rotating assembly, the receiving plate 4 can be rotatably installed in the inner cavity of the fixing groove 3. When adjusting the processing angle of the aluminum alloy casting, the rotation of the receiving plate 4 will drive the rotating ring 18 on its surface to slide in the inner cavity of the rotating groove 19.

[0030] Furthermore, a support column 5 is fixedly connected to the bottom of the receiving plate 4, and the bottom end of the support column 5 is rotatably connected to the inner wall of the support frame 2. The inner cavity of the support frame 2 is equipped with a driving component for driving the receiving plate 4 to rotate so as to adjust the finishing angle of the aluminum alloy casting. The driving component includes a driving motor 6 arranged at the bottom of the support shell 1, and the output shaft of the driving motor 6 passes through the support shell 1 and extends to the inner cavity of the support shell 1. The output shaft of the driving motor 6 is fixedly installed with a driving gear 7, and the surface of the support column 5 is fixedly installed with a gear ring 8 meshing with the driving gear 7.

[0031] The processing angle of the aluminum alloy casting can be adjusted by setting the drive assembly. Specifically, when adjusting, the user can turn on the drive motor 6 through the external controller, and the output shaft of the drive motor 6 will drive the drive gear 7 to rotate. The rotation of the drive gear 7 will drive the support column 5 to rotate through the gear ring 8, and then drive the aluminum alloy casting to rotate through the receiving plate 4 to adjust its processing angle.

[0032] In addition, the user can manually rotate the aluminum alloy casting to directly adjust its processing angle. In this case, the user needs to install a positioning device on the device to fix the adjusted processing angle of the aluminum alloy casting.

[0033] Furthermore, a support assembly for supporting the drive motor 6 is installed at the bottom of the support shell 1, and the support assembly includes a support plate 9 arranged below the drive motor 6, and side plates 10 are fixedly installed on both sides of the top of the support plate 9, and the top of the side plate 10 is fixedly connected to the bottom of the support shell 1, and the bottom of the drive motor 6 is fixedly installed on the top of the support plate 9.
