[0027] To make the objectives, technical solutions, and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is apparent that the embodiments described are only some, not all, of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0028] The hull 10 is often filled with buoyancy material 11. The traditional filling process has the following two problems:

[0029] (1) It requires multiple machining operations, which is inefficient.

[0030] The buoyancy material 11 is loaded into the semi-finished shell 10 blank. After the buoyancy material 11 and the shell 10 are completely bonded together, the shell 10 and the buoyancy material 11 are machined to meet the drawing requirements. This process requires at least two machining operations, making it cumbersome and inefficient.

[0031] (2) The product has high precision, but the size is difficult to guarantee and the pass rate is low.

[0032] The buoyancy material 11 is primarily attached to the housing 10 by bonding. During machining, the cutting force can cause the buoyancy material 11 to shift position, introducing numerous uncertainties and failure factors. This makes it difficult to guarantee a high product quality rate if the product's dimensional accuracy is high.

[0033] In order to solve the above problems, the present invention provides a compacting and positioning device for filling buoyancy material 11. The device is easy to operate and can not only improve the filling efficiency but also effectively improve the product qualification rate.

The interior of the second punch 3 is a cross-shaped structure. A second through hole is defined at the center of the second punch 3. Specifically, the second through hole is defined at the center of the cross-shaped structure. The second punch 3 is made of stainless steel or aluminum alloy, or a hard material, such as a polymer material (such as ABS, polyamide, etc.).

[0043] The third punch 4 has an outer surface in contact with the top of the buoyancy material 11 , and is used to press the top of the buoyancy material 11 .
