[0003] Leisure chair frame Figure 1 As shown, it is formed by welding a first square tube 11 and two second square tubes 12. The two second square tubes 12 are respectively located on both sides of the first square tube 11. The two ends of the first square tube 11 and the end of the second square tube 12 close to the first square tube 11 are processed by cutting angles so that they can be spliced ​​together in a state of being perpendicular to each other, and then the joints of the first square tube 11 and the second square tube 12 are welded.

[0004] At present, in the production of leisure chair frames, the operator places the first square tube and the second square tube on the table and assembles them, and then uses a welding gun to connect the joints. Due to the position error of manual assembly, and the welding position of the welding gun will be different each time, it is easy to affect the accuracy of the leisure chair frame produced.

[0028] The embodiment of the present application discloses a kind of high-efficiency automatic welding processing equipment for a leisure chair frame.

The welding robot 2 is a commonly used device and belongs to the existing mature technology, which will not be repeated here.

[0030] Reference Figure 1-Figure 3 The operator places the first square tube 11 and the second square tube 12 with the help of the limiting component 5, and then locks the first square tube 11 and the second square tube 12 through the locking component 6, and finally welds the first square tube 11 and the second square tube 12 to be connected through the welding robot 2. During the whole process, whether it is the placement of the first square tube 11 and the second square tube 12 or the welding of the connection, it is completed with the help of mechanical equipment, which can improve the accuracy of the leisure chair frame 1.

[0031] Reference Figure 1-Figure 3 The limiting assembly 5 includes multiple groups of limiting members 51, each group of limiting members 51 includes two limiting columns 52, the limiting columns 52 are fixedly arranged on the mounting frame 4, and the gap between the two limiting columns 52 only accommodates the width of the first square tube 11 or the second square tube 12. The first square tube 11 or the second square tube 12 is limited by at least two groups of limiting members 51, and the two groups of limiting members 51 are respectively close to the two ends of the first square tube 11 or the second square tube 12.

[0032] Reference Figure 1-Figure 3The limiting assembly 5 also includes a first motor 53, a transmission belt 54, a rotating shaft 55 and a plurality of rollers 56. The rotating shaft 55 rotates on the mounting frame 4. The rotation axis direction of the rotating shaft 55 is parallel to the length direction of the first square tube 11. The roller 56 is coaxially fixed on the rotating shaft 55. The roller 56 is located on the side of the second square tube 12 close to the mounting frame 4, and the roller 56 abuts against the second square tube 12.

[0033] Reference Figure 1-Figure 3 The first motor 53 is fixedly mounted on the mounting frame 4, the axial direction of the first motor 53 is parallel to the axial direction of the rotating shaft 55, the transmission belt 54 is wound around the rotating shaft 55 and the output shaft of the first motor 53, and the roller 56 is used to drive the second square tube 12 to move toward the first square tube 11.

[0034] Reference Figure 1-Figure 3 After the operator has roughly placed the first square tube 11 and the two second square tubes 12, the operator drives the output shaft of the first motor 53 to rotate, and drives multiple rollers 56 to rotate through the rotating shaft 55. The rollers 56 abut against the bottom surface of the second square tube 12 to drive the second square tube 12 to move toward the first square tube 11, so that the end of the second square tube 12 can be aligned with and close to the end of the first square tube 11. When the thrust is sufficient, the first square tube 11 can also automatically move to the standard position, which can help the operator to place the first square tube 11 and the second square tube 12 more quickly and improve the welding efficiency.

[0035] Reference Figure 1-Figure 3 The locking assembly 6 includes a plurality of quick clamps 61 , which are disposed on the mounting frame 4 and are used to press the second square tube 12 onto the mounting frame 4 . The second square tube 12 is locked by at least one quick clamp 61 .

Since the roller 56 needs to push the second square tube 12 forward, the end of the rubber sleeve will exceed the surface of the mounting frame 4 when there is no external force. When the locking assembly 6 locks the second square tube 12, the second square tube 12 can press the rubber sleeve to deform the rubber sleeve, so that the bottom surface of the second square tube 12 can completely abut against the mounting frame 4, reducing the deformation of the second square tube 12.
