Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a welding auxiliary device for chair processing. Background Technology

[0002] Chairs are a common type of furniture, widely used in daily life and office environments. Their design typically incorporates various square tubes of different sizes and shapes, which serve as support components and are distributed throughout different parts of the chair.

[0003] During the processing of these square tubes, threaded metal parts need to be welded to the openings on the tubes using welding equipment. Currently, the operator directly installs the metal parts onto the square tubes and then holds the tubes to the welding equipment for welding. During this process, the operator is very close to the welding equipment, and the bright light generated during welding can easily damage their eyes. Therefore, it is necessary to design a welding auxiliary device for chair processing. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a welding auxiliary device for chair processing.

[0005] The objective of this utility model can be achieved through the following technical solution: A welding auxiliary device for chair processing, comprising a base, characterized in that a switching disk is rotatably mounted on the base, the switching disk is connected to a power module that enables it to rotate, four electric linear tracks are horizontally mounted on the switching disk and are evenly distributed, the slides of the electric linear tracks are connected to the moving platform, a plurality of placement beams for placing chair workpieces are mounted on the moving platform, one end of the placement beam has an end limiting block, clamping cylinders are mounted on both sides of the moving platform, the piston rod end of the clamping cylinder is connected to a clamping bar, and the clamping bar is arranged at the other end of the placement beam, and an opaque baffle is also mounted on the base via a bracket.

[0006] Two side limiting plates are installed on the end limiting block.

[0007] An auxiliary component is also installed on the end limiting block, and a magnet is installed on the auxiliary component.

[0008] The base is equipped with multiple support legs.

[0009] The power module includes a reducer, a power motor, a first pulley, a second pulley, and a belt. The reducer and the power motor are both mounted on the base.

[0010] Compared with existing technologies, this welding auxiliary device for chair processing has the following advantages: In this invention, several placement beams for fixing chair workpieces are installed on a movable platform. The movable platform is set on a switching plate, allowing the operator to move away from the welding equipment when picking up or placing chair workpieces. In addition, an opaque baffle is set to block the welding light from the welding equipment, thereby greatly protecting the operator's eyes. Attached Figure Description

[0012] 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.

[0013] like Figures 1-4As shown, the welding auxiliary device for chair processing includes a base 1, on which a switching disk 5 is rotatably mounted. The switching disk 5 is connected to a power module that enables its rotation. In this embodiment, the switching disk 5 can rotate 90 degrees at a time. The placement beam 2 on one side of the opaque baffle 3 is used for loading and unloading, while the placement beam 2 on the other side is used for welding. Welding can be performed using existing welding equipment to weld the internally threaded metal part 20 to the square tube workpiece 19 used to make the chair. Four electric linear tracks 6 are horizontally mounted on the switching disk 5 and are evenly distributed. The slide table 6a of the electric linear track 6 is connected to the moving table 4. After the corresponding placement beam 2 rotates to the welding equipment, the electric linear track 6 drives the moving table 4 to move horizontally, so that the placement beam 2 on the moving table 4 moves sequentially to the welding equipment, completing the process. Welding function; The moving table 4 is equipped with several placement beams 2 for placing chair workpieces. One end of each placement beam 2 has an end limiting block 12, and two side limiting plates 11 are installed on the end limiting block 12. An auxiliary component 10 is also installed on the end limiting block 12, and a magnet 18 is installed on the auxiliary component 10. Clamping cylinders 8 are installed on both sides of the moving table 4. The piston rod end of the clamping cylinder 8 is connected to the clamping bar 9, and the clamping bar 9 is arranged at the other end of the placement beam 2. In this embodiment, one end of the square tube workpiece 19 is inserted into the two side limiting plates 11 and abuts against the end limiting block 12. The clamping cylinder 8 drives the clamping bar 9 to move, and the clamping bar 9 abuts firmly against the other end of the square tube workpiece 19, thereby fixing the square tube workpiece 19 on the placement beam 2. An opaque baffle 3 is also installed on the base 1 by a bracket.

[0014] Multiple support legs 7 are installed on the base 1.

[0015] The power module includes a reducer 17, a power motor 13, a first pulley 16, a second pulley 14, and a belt 15. The reducer 17 and the power motor 13 are both mounted on the base 1. The switching disk 5 is fixed on the output shaft of the reducer 17. The first pulley 16 is mounted on the input shaft of the reducer 17, and the second pulley 14 is mounted on the output shaft of the power motor 13. The belt 15 is sleeved between the first pulley 16 and the second pulley 14. With this structure, the power motor 13 drives the second pulley 14 to rotate, and the second pulley 14 drives the reducer 17 to move through the belt 15. The reducer 17 causes the switching disk 5 to rotate.

[0016] In this invention, several placement beams 2 for fixing chair workpieces are installed on a movable platform 4. At the same time, the movable platform 4 is set on a switching plate 5. When the operator picks up or puts down the chair workpieces, he or she can stay away from the welding equipment. In addition, an opaque baffle 3 is set to block the welding light from the welding equipment, thereby greatly protecting the operator's eyes.

[0017] 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.

[0018] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model.
