[0002] In the process of developing solid rocket engines, with the changes in the external working environment, higher requirements are put forward for its outer layer protection, requiring the outer protective coating to have multiple functions. The outer protective coating of solid rocket engines has developed from resin-based outer protective coating to rubber-based flexible outer protective coating, and the coating structure has also developed from a single coating to a composite coating structure. The new special coating has put forward higher requirements for the substrate coating process.

[0003] The current commercially available tools have poor adaptability and are not suitable for non-standard equipment maintenance and coating scraping. With the increase in production demand, the types of coating molding products have increased from a few to more than 40. The external heat-resistant coating needs to be repaired and cut in many places, with a wide distribution and high requirements. The existing tools are limited in their applicable environment and have a single application range for reciprocating machines or robots. A single commercially available tool is only suitable for specific interfaces of specific equipment, which has limitations in actual application. For example, the sizes of maintenance wrenches for diaphragm pumps, reciprocating machines, robots and other equipment are all different. In order to ensure the timeliness of maintenance, on-site personnel have to deal with routine redundant operations such as complicated replacement of maintenance tools and inconvenience in carrying.

[0004] When personnel perform macro repairs or cutting on coatings, they currently use single-sided blades, which have problems such as inconvenient operation, uneven force, easy loss when carrying, and inability to guarantee cutting distance. Summary of the invention

[0005] The technical problem solved by the present invention is: in order to solve the problems of low maintenance efficiency when personnel use tools purchased in the market, the need to carry a large number of special-type tools, the inability to accurately and quickly position paint cutting operations, and difficulty in opening raw material packaging, a multifunctional portable maintenance tool suitable for coating forming is proposed, which can realize the maintenance of spraying equipment such as multiple models of robots, reciprocating machines, diaphragm pumps, portable opening of raw material packaging, and macro-cutting measurement of coatings.

[0006] The technical solution of the present invention is:

[0007] A multifunctional portable maintenance tool suitable for coating molding, comprising: a tool body, a cutting blade, a bayonet, a package opening device, a finger-like gripping part, and a 100 mm scale;

[0008] The head of the tool body is a cutting blade, and the tail is designed with a packaging opening device; a plurality of bayonet holes of different sizes are arranged on the tool body; a 100mm scale is arranged on one side of the tool body, and a finger-like gripping part is arranged on the other side.

[0009] Furthermore, a 100 mm scale is used to measure the portion of the coating to be cut.

[0010] Furthermore, the cutting head is used to cut the outer protective coating of the solid rocket motor.

[0011] Furthermore, the finger-like gripping portion is used for gripping the tool body with fingers.

[0012] Furthermore, the maintenance tool is an integrated structure and is made of stainless steel.

[0013] Furthermore, the bayonet is located in the middle of the tool body, and the bayonet is a hexagonal bayonet, corresponding to a hexagonal bolt, including four specifications and sizes of 15.5mm, 21.5mm, 23.5mm, and 26.5mm.

[0014] Furthermore, the package opening device adopts a 2 / 3 circular design, and the end of the arc has a 60° barb for opening tinplate and plastic packaging covers.

[0015] The beneficial effects of the present invention compared with the prior art are:

[0016] (1) The present invention can solve the problems of low maintenance efficiency when personnel use tools purchased in the market, the need to carry a large number of special-type tools, the inability to accurately and quickly locate paint cutting operations, and the difficulty in opening raw material packaging.

[0017] (2) The multifunctional portable maintenance tool of the present invention overcomes the defects of the existing tools on the market that have single functions and are complicated.

[0018] (3) The main body of the present invention is a stainless steel structure, which meets the requirements of work strength. The side of the main body is designed with a finger-like grip shape for easy gripping by personnel;

[0019] (4) For the disassembly and assembly of parts on some special equipment such as robots, reciprocating machines, diaphragm pumps, etc., because such equipment is compactly installed and has a small maintenance space, it is difficult to repair with normal tools, and some parts cannot be disassembled normally. The tool of the present invention allows personnel to work more quickly and conveniently in a small space, without the need to replace tools multiple times, and can remove parts in special positions.

[0020] (5) The present invention realizes lightweight and quick product micro-repair. Instead of using a traditional single-sided blade plus a scale, the operator can use this tool to quickly and accurately cut the coating.

[0021] (6) The present invention solves the problem that there is no special tool for opening the raw material packaging. When the operator uses the tool, it is ensured that the operator is not injured, the packaging is opened without damage, and the packaging can be reused. BRIEF DESCRIPTION OF THE DRAWINGS
