[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] The specific technical solution of this utility model is as follows:

[0020] In one specific embodiment, such as Figure 1 and Figure 2 As shown, this utility model provides a fixing device for processing aluminum die castings, including a base plate 1, a positioning mechanism and a clamping mechanism;

[0021] The positioning mechanism includes a support plate 2, which is vertically installed on the top of the base plate 1, and a circular positioning boss 3 is provided on the side of the support plate 2, and a drill bit avoidance notch 4 is provided on the top of the circular positioning boss 3.

[0022] The clamping mechanism includes a mounting base 5, a manual translation drive assembly, and a pressure bar 6. The mounting base 5 is located at the bottom of the base plate 1. The manual translation drive assembly includes a drive seat 7, a push-pull handle 8, a translation rod 9, and a connecting rod 10. The drive seat 7 is located at the top of the mounting base 5, and the top of the drive seat 7 is provided with a guide sleeve 11 and a connecting ear 12. The guide sleeve 11 is located between the connecting ear 12 and the support plate 2. The bottom of the push-pull handle 8 is hinged to the connecting ear 12. The translation rod 9 is movably inserted through the guide sleeve 11. The connecting rod 10 is located between the push-pull handle 8 and the translation rod 9, and both ends of the connecting rod 10 are respectively hinged to the bottom of the push-pull handle 8 and one end of the translation rod 9. The pressure bar 7 is fixedly connected to the other end of the translation rod 9.

[0023] The above solution is adopted: When using the fixing device for processing aluminum die castings according to this utility model, the aluminum die casting 100 to be drilled is fitted onto the outside of the circular positioning boss 3. The operator pushes the push-pull handle 8 to rotate, so that the push-pull handle 8 drives the translation rod 9 and the pressure strip 6 fixed to the translation rod to move towards the support plate 2 through the connecting rod 10 until the pressure strip 2 contacts the aluminum die casting 100 and presses and fixes the aluminum die casting 100. Then, the top side wall of the aluminum die casting 100 can be drilled. After the drilling is completed, the operator pulls the push-pull handle 8 to rotate, so that the push-pull handle 8 drives the translation rod 9 and the pressure strip 6 fixed to the translation rod 9 to move away from the support plate 2 through the connecting rod 10, so that the pressure strip 2 separates from the aluminum die casting 100 and releases the aluminum die casting 100. Finally, the aluminum die casting with the completed drilling is removed.

[0024] In another specific embodiment, such as Figure 2 and Figure 4 As shown, the outer edge of the circular positioning boss 3 is provided with multiple positioning slots 13.

[0025] The above solution is adopted: by setting a positioning slot 13 to engage with the protrusion 101 on the inner side of the aluminum die casting 100, the positioning effect of the aluminum die casting is improved, the accuracy of the drilling position is guaranteed, and the aluminum die casting 100 is prevented from rotating during the drilling process, so as not to affect the drilling effect.

[0026] In another specific embodiment, such as Figure 3 As shown, the top of the support plate 2 is provided with a drill bit guide block 14, and the drill bit guide block 14 is provided with a drill bit through hole 15 corresponding to the drill bit avoidance notch 4.

[0027] The above solution is adopted: When drilling, the drill bit will pass through the drill bit through hole 15 from above the drill bit guide block 14 and then act on the aluminum die casting 100. Therefore, the drill bit guide block 14 can guide the vertical movement of the drill bit through the drill bit through hole 15, so that the drill bit can accurately act on the drilling position of the aluminum die casting 100.

[0028] In another specific embodiment, such as Figure 1 As shown, a reinforcing rib 16 connects the support plate 2 and the base plate 1.

[0029] The above solution, by setting reinforcing ribs 16, helps to improve the connection strength between the support plate 2 and the base plate 1.

[0030] In another specific embodiment, such as Figure 1 As shown, the drive seat 7 is fixedly connected to the mounting seat 5 through the connecting hole 17.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
