Description

Technical Field

[0001] This utility model relates to the field of aviation sealant application technology, specifically to a rotary adhesive remover. Background Technology

[0002] In the aerospace field, aviation sealants, as core materials for ensuring the structural integrity, safety and reliability of aircraft, are widely used in important scenarios such as fuselage structural sealing, protection of critical parts of aero engines, fuel system leak prevention and moisture protection of electronic equipment compartments due to their excellent performance.

[0003] However, once the aviation sealant has cured, descaling becomes a necessary step in subsequent maintenance. In-depth research revealed that most current descaling methods are traditional manual methods, which are not only difficult to use but also consume significant manpower and time, and have extremely low efficiency. This makes it difficult to meet the stringent requirements of the aerospace industry for efficient and precise maintenance operations, becoming a major bottleneck restricting the maintenance process.

[0011] Preferably, the bottom ends of the four external blades are respectively lower than the bottom end face of the tapered section of the blade head.

[0012] Preferably, the hollow area is formed by the space between the bottom ends of the four external blades and the bottom end face of the blade head.

[0013] Preferably, the inner diameter of the circumference formed by the outer edges of the bottom ends of the four external blades is larger than the diameter of the cylindrical section of the blade head.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] like Figures 1-2As shown, this utility model provides a rotary adhesive remover, including a handle 1 and a blade head 2. The blade head 2 is connected to one end of the handle 1. The outer wall of the blade head 2 is provided with multiple external blades 3. The multiple external blades 3 are equidistantly arranged along the circumference of the blade head 2, and the multiple external blades 3 are all arc-shaped. The surface of the external blades 3 is provided with an angled scraping blade 4. The scraping blade 4 can be used to remove surface sealant, and the end of the blade head 2 away from the handle 1 is a hollow area 5.

[0025] Furthermore, the longitudinal section of the handle 1 is shaped like a plum blossom. The use of a plum blossom-shaped handle 1 allows this adhesive remover to be directly clamped onto the universal drill chuck of various tools without the need for additional adapters. This significantly improves the versatility and ease of use of the tool, enables quick changeovers, and greatly improves work efficiency.

[0026] As a further step, the external blade 3 is made of polyoxymethylene (POM) hardened material. After the material is treated, it can ensure that the external blade 3 has certain wear resistance, self-lubrication and good dimensional stability, while significantly improving hardness, ensuring that the external blade 3 is not easily worn or deformed during use, and can efficiently complete the glue removal operation.

[0027] As a further step, the cutter head 2 includes a cylindrical section and a conical section. One side of the cylindrical section of the cutter head 2 is connected to one end of the handle 1. Four external blades 3 are provided, and the four arc-shaped external blades 3 are set from the cylindrical section of the cutter head 2 to the conical section of the cutter head 2. The bottom ends of the four external blades 3 are lower than the bottom end face of the conical section of the cutter head 2, and the bottom ends of the four external blades 3 are all on the same horizontal plane.

[0028] As a further step, the hollow area 5 is formed by the space between the bottom ends of the four external blades 3 and the bottom end face of the blade head 2. The design of the hollow area 5 can be used to avoid certain non-adhesive removal areas.

[0029] Furthermore, the inner diameter of the circumference formed by the outer edges of the bottom ends of the four external blades 3 is larger than the diameter of the cylindrical section of the blade head 2, the bottom end face diameter of the conical section of the blade head 2 is smaller than the top surface diameter of the cylindrical section of the blade head 2, and the bottom end face diameter of the conical section of the blade head 2 is larger than the diameter of the handle 1.

[0030] The working principle and usage process of this utility model are as follows: Utilizing the design of the plum blossom-shaped handle 1, this rotary adhesive remover can be quickly clamped onto the universal drill chuck of various tools. Then, through the angled bottom scraper blade 4 on the external blade 3, the sealant can be effectively removed. Compared with traditional manual operation, the adhesive removal effect is better, and the adhesive removal efficiency is significantly improved, greatly shortening the operation time. At the same time, the arc-shaped external blade 3, made of polyoxymethylene (POM) hardened material, gives the rotary adhesive remover excellent wear resistance, a long service life, and reduces replacement costs. Thus, when this adhesive remover is used in conjunction with external tools, it can ensure efficient physical adhesive removal through strong mechanical power.
