Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a tooling for spray painting the surface of chair legs. Background Technology

[0002] Chair legs, as an indispensable basic component of a chair structure, bear the important function of supporting the weight of the entire chair and maintaining stability. During the manufacturing process of chair legs, to improve their aesthetics, enhance durability, and prevent the wood from being damaged by moisture and decay, their surface must be painted. With the continuous growth of personalized demands, it is often necessary to paint chair legs of different lengths with different colors. However, in current technology, only one spray gun is typically provided, making it difficult to conveniently meet these personalized painting needs. Therefore, designing a fixture for painting the surface of chair legs is essential. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a tooling for spray painting chair legs.

[0004] The objective of this utility model can be achieved through the following technical solution: A chair leg surface painting fixture, comprising a base plate, characterized in that an electric linear track is vertically mounted on the base plate, the slide of the electric linear track is connected to a lifting arm, a rotary motor is mounted on the lifting arm, and the output shaft of the rotary motor is horizontally arranged, the end of the output shaft of the rotary motor is connected to a switching disc, a plurality of spray guns for chair leg painting are mounted on the switching disc, and the spray guns are evenly distributed in a ring, a bracket is mounted on the base plate, a reduction motor is mounted on the bracket, and the output shaft of the reduction motor is vertically upward, the end of the output shaft of the reduction motor is connected to a rotating table, and a finger cylinder for clamping the chair leg is mounted on the rotating table.

[0005] A column is also installed on the base plate. An adjusting seat is slidably connected to the column. A locking screw is threaded onto the adjusting seat. A pressing cylinder is also installed on the adjusting seat. The piston rod end of the pressing cylinder is connected to a movable block. An intermediate block is installed on the movable block via a spring. A pin is rotatably connected to the intermediate block.

[0006] The locking screw is a hand-tightening component.

[0007] The fingertip of the finger cylinder is equipped with a clamping block.

[0008] The finger cylinder is also equipped with a placement block with positioning holes.

[0009] Compared with existing technologies, this chair leg surface painting fixture has the following advantages:

[0010] In this invention, multiple spray guns are mounted on a rotating plate, allowing for quick switching of the required spray gun according to actual needs. At the same time, with the help of the finger cylinder and the ejector pin, chair legs of different lengths can be clamped, thus facilitating personalized painting operations for chair legs of different lengths.

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figures 1-2As shown, the painting fixture for the chair leg 22 includes a base plate 1. An electric linear track 2 is vertically mounted on the base plate 1. The slide 2a of the electric linear track 2 is connected to a lifting arm 4. The electric linear track 2 is an existing product, allowing the slide 2a to move up and down as needed. A rotary motor is mounted on the lifting arm 4, and the output shaft of the rotary motor is horizontally positioned. The end of the output shaft of the rotary motor is connected to a switching disc 5. Multiple spray guns 6 for painting the chair leg 22 are mounted on the switching disc 5, and the spray guns 6 are evenly distributed in a ring. In this example, each spray gun 6 can spray different colors of paint, which is an existing technology. Simultaneously, the rotary motor drives the switching disc to rotate, making the corresponding spray gun 6 horizontal and in the working position. A bracket 17 is mounted on the base plate 1, and a reduction motor 16 is mounted on the bracket 17. The output shaft of the reduction motor 16 is vertically upward. The output shaft end is connected to the rotating table 18, and the rotating table 18 is equipped with a finger cylinder 19 for clamping the chair leg 22; the base plate 1 is also equipped with a column 14, and an adjusting seat 12 is slidably connected to the column 14. A locking screw 13 is threadedly connected to the adjusting seat 12, and a pressing cylinder 11 is also installed on the adjusting seat 12. The piston rod end of the pressing cylinder 11 is connected to the movable block 10. A middle block 15 is installed on the movable block 10 through a spring 9. A pin 8 is rotatably connected to the middle block 15. With this structure, after adjusting the position of the movable block 10 according to the length of the chair leg 22, the screw at the upper end of the chair leg 22 is clamped by the clamping block 20 of the finger cylinder 19. The pressing cylinder 11 drives the pin 8 to move downward, and the pin 8 assists in positioning the lower end of the chair leg 22. The rotating table 18 is driven to rotate by the reduction motor 16, and the rotating table 18 drives the finger cylinder 19 to rotate, thereby driving the chair leg 22 to rotate.

[0016] Locking screw 13 is a hand-tightening component.

[0017] A clamping block 20 is installed at the finger tip of the finger cylinder 19.

[0018] The cylinder body of the finger cylinder 19 is also equipped with a placement block 21 with positioning holes. With this structure, the placement block 21 plays an auxiliary positioning role when clamping the chair leg 22.

[0019] In this invention, multiple spray guns 6 are mounted on a rotating plate, which can quickly switch the required spray guns 6 according to actual needs; at the same time, with the help of the finger cylinder 19 and the ejector pin 8, chair legs 22 of different lengths can be clamped, which facilitates personalized painting operations for chair legs 22 of different lengths.

[0020] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0021] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
