Description

Technical Field

[0001] This utility model belongs to the field of spray painting technology, and in particular relates to a combination tooling for spray painting protection of inner and outer surfaces for projectile head screws. Background Technology

[0002] There are no suitable lifting and protective fixtures for the projectile head screw during surface treatment; it is necessary to use wire to lift it for painting, and this requires... Figure 1 The upper internal thread surface to the external thread area, bottom surface, bottom thread, and bottom inner end face of the head screw are protected to ensure that the inner and outer surfaces of these areas are not covered by paint during painting. Currently, the method used is to apply masking tape and cut it according to the shape. After painting, the masking tape and residual adhesive need to be removed. This method is time-consuming and labor-intensive, and is prone to problems such as deformation of the masking tape, resulting in excess paint in non-painted areas and obscuring of painted areas. There will be a lot of paint repair required after painting. Utility Model Content

[0003] The technical problem to be solved by this utility model is: to design a tooling that can protect the inner and outer surfaces of the projectile head screw when painting.

[0004] To solve the above-mentioned technical problems, the specific technical solution of this utility model is as follows: A lifting fixture with internal and external surface painting protection includes a lifting tool 1 and a protective sleeve 2. The upper end of the lifting tool 1 is hexagonal prism-shaped, and the lower end is a ring. The inner wall of the ring is provided with an internal thread, which mates with the external thread at the upper end of the projectile head screw. The upper end of the lifting tool 1 is provided with a lifting hole. The protective sleeve 2 is cylindrical, with an external thread on its outer surface, which mates with the bottom thread of the projectile head screw. The bottom of the protective sleeve 2 is provided with an outward-facing annular flange for mates with the bottom end face of the projectile head screw.

[0005] This utility model has the following advantages: the combination of the upper lifting device and the lower protective sleeve can solve the problem of protection during hoisting and painting of inner and outer surfaces, and can also improve production efficiency and reduce the amount of labor. Attached Figure Description

[0006] Figure 1 This is a schematic diagram of the projectile headstock structure; Figure 2 This is a combination tooling for internal and external surface painting protection during hoisting; Figure 3 A schematic diagram of the working process of the combined tooling for spraying protective paint on the inner and outer surfaces for hoisting. Detailed Implementation

[0007] To better understand the purpose, structure, and function of this utility model, a more detailed description of this utility model is provided below with reference to the accompanying drawings.

[0008] This embodiment comprehensively analyzes the structure of the head screw, the requirements for painting the inner and outer surfaces, and the convenience of production operations, and designs an appendix. Figure 2 The hoisting protection combination tool can replace wire hoisting, provide protection for the top end of the bolt, and also provide protection for the bottom end face, bottom thread, and bottom inner end face, while facilitating the painting protection operation of the inner and outer surfaces.

[0009] The combined internal and external surface painting and protection fixture for hoisting not only protects the non-painted area at the bottom of the screw head without hindering the spray gun and paint from entering the inner surface for painting, but also protects the non-painted area at the top of the screw head. It is suitable for hoisting operations across multiple production lines. This fixture not only meets the requirements for painting screw heads but also solves problems such as pasting masking tape, cutting to shape before painting, removing masking tape after painting, residual adhesive, and masking tape deformation leading to excess paint in non-painted areas and obscuring painted areas. It provides convenience for operators, reduces the difficulty of hoisting and protection operations, and increases production efficiency from 330 hours / 1000 pieces to 85 hours / 1000 pieces.

[0010] When using, install the hoisting protective gear according to the attached instructions before painting the inner and outer surfaces. Figure 3 The fixture is installed at both ends of the head screw in a certain manner. When the inner surface is painted, the bottom fixture can protect the non-painted area at the bottom of the head screw, while not affecting the spray gun and paint from entering the inner surface to complete the painting. When the outer surface is painted, the upper fixture can protect the non-painted area at the top of the head screw, and can also be used for hoisting in multi-production line operations.

[0011] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and improvements without departing from the principles of the present invention, and these modifications and improvements should also be considered to fall within the protection scope of the present invention.
