Description

TECHNICAL FIELD

[0001] The utility model relates to the field of automobile hub production and manufacturing, especially a tool for installing automobile hub decoration nails. BACKGROUND

[0002] In the automobile hub production and manufacturing process, in order to be beautiful, several rivets are often installed on the final qualified automobile hub to beautify, which plays a decorative effect. This rivet is called a decoration nail.

[0003] Most of the existing decoration nails are composed of a rivet head with a relatively simple shape and a cylindrical rivet rod, which is not beautiful and is prone to over-tightening or over-loosening, affecting assembly quality and efficiency. Therefore, a kind of automobile aluminum alloy hub decoration rivet is disclosed in Chinese patent application publication No. CN106194950A. In order to make the rivet rod part more tightly installed in the mounting hole, a counterbore is provided in the middle of the end face of the rivet head, which facilitates the application of force to the counterbore, and then the expansion structure provided on the rivet rod expands outward. However, due to the limitation of production cost, the decoration nail has high brittleness, and if the end face of the rivet head is directly struck by the installation tool during the striking installation process, the structure around the counterbore will be damaged, resulting in a very low installation efficiency of the decoration nail. SUMMARY

[0017] The technical scheme of the utility model will be further illustrated below by specific embodiments in combination with the drawings.

[0018] One embodiment of the present application is as follows: Figs. 1 to 3As shown, the decorative nail 10 is composed of a rivet head 11 and a cylindrical rivet rod 12, and a counterbore 13 is arranged in the middle of the end face of the rivet head. A tool for installing decorative nails of automobile hubs comprises a hammer 200 and a pressing piece; the pressing piece comprises a column 110 and a pressing pin part 120; one end of the column 110 is a knocking end, and the other end of the column 110 is a pressing end; the end face of the pressing end is provided with a blind hole along the axial direction of the column 110; one end of the pressing pin part 120 is provided with an insertion end 121 capable of being inserted into the counterbore of the decorative nail, and the other end of the pressing pin part 120 is a connecting end 122, which is detachably mounted in the blind hole of the column 110 along the axial direction of the column 110.

[0019] The tool is additionally provided with the pressing piece with a special structure, and the pressing end of the pressing piece can be integrally attached to the rivet head of the decorative nail, so that the force applied to the decorative nail during the knocking installation process is more uniform, and the decorative nail is less likely to crack, thereby greatly improving the installation efficiency of the decorative nail of the automobile hub.

[0020] The end face of the pressing end of the column 110 extends outward along the axial direction of the column 110 and is provided with a connecting pipe 111; the inside of the connecting pipe 111 is provided with the blind hole; the outer wall of the connecting pipe 111 is provided with external threads; the pressing end of the column 110 is provided with a pressing pipe 112; one end of the pressing pipe 112 is sleeved on the outer wall of the connecting pipe 111 through internal threads; the other end of the pressing pipe 112 is provided with a pressing ring 113, which is sleeved on the outside of the insertion end 121. By rotating the pressing pipe 112, the position of the pressing ring 113 can be adjusted, thereby meeting the installation of decorative nails of more specifications.

[0021] The insertion end 121 and the pressing ring 113 are made of PVC. Direct contact of the decorative nail with rigid materials is avoided, which can more likely protect the decorative nail from being damaged during installation. The column 110 is made of hard plastic, such as the plastic king material well known to those skilled in the art, and the hammer 200 is made of soft plastic.

[0022] The inner wall of the blind hole is provided with internal threads; the connecting end 122 of the pressing pin part 120 is provided with external threads, and the connecting end 122 of the pressing pin part 120 is detachably mounted in the blind hole of the column 110 along the axial direction of the column 110. By rotating the pressing pin part 120, the length of the insertion end 121 of the pressing pin part 120 can be adjusted, thereby adapting to the installation of decorative nails with counterbores of more different depths.

[0023] The insertion end 121 of the ejector pin part 120 is a regular quadrangular prism, a regular pentagonal prism, a regular hexagonal prism, a regular octagonal prism or a cylinder; the outer wall of the ejector tube 112 is provided with anti-skid protrusions 114. Because there are many types of decorative nails, the insertion end 121 of the ejector pin part 120 needs to be replaced into a corresponding shape according to the needs, so that the insertion end 121 can be inserted into the counterbore of the decorative nail, thereby achieving better positioning and ejecting effect; the outer wall of the ejector tube 112 is provided with anti-skid protrusions 114, so as to facilitate the operator to make the ejector tube 112 relatively rotate relative to the connecting tube 111, thereby more conveniently adjusting the position of the ejector tube 112, so that when the insertion end 121 is inserted into the bottom of the counterbore of the decorative nail, the ejector ring 113 provided on the ejector tube 112 also tightly abuts against the end face of the decorative nail, thereby making the decorative nail as a whole under the action of the tooling tool, so that the decorative nail will not easily break due to uneven stress during the knocking installation process, and the installation efficiency is higher.
