[0029] like Figures 1 to 6 As shown, a short rocker for a precision industrial robot that is easy to weld comprises a short rocker body, wherein the short rocker body comprises a rocker seat 1, an arc rod 3 and a rocker head 4, wherein the rocker seat 1 is arranged at one end of the bottom of the arc rod 3, and the rocker head 4 is arranged at one end of the top of the arc rod 3; a first wing plate 11 is arranged on the outer peripheral wall of the rocker seat 1, and a second wing plate 41 is arranged on the outer peripheral wall of the rocker head 4; the short rocker body is tiltedly arranged on a welding fixing frame 2, and a positioning mechanism is arranged on the welding fixing frame 2, and the positioning mechanism positions the first wing plate 11 and the second wing plate 41 respectively; the overall size of the rocker seat 1 is larger than the rocker head 4, and a mounting buckle 12 is arranged on the outer peripheral wall of the rocker seat 1, and a limiting mechanism is arranged on the welding fixing frame 2, and the limiting mechanism limits the two sides of the mounting buckle 12; an adjusting mechanism is arranged on the welding fixing frame 2, and the adjusting mechanism fixes the two sides of the arc rod 3.

[0030] The first wing plate 11 and the second wing plate 41 are accurately positioned respectively by the positioning mechanism on the welding fixture 2 to ensure that the position of the short rocker body is accurate during the welding process. At the same time, the limiting mechanism limits the two sides of the mounting buckle 12 to further strengthen the installation stability of the short rocker body. The adjustment mechanism fixes the two sides of the arc rod 3 to improve the overall installation stability of the short rocker body. During the welding process, a stable posture can be maintained to reduce errors caused by vibration or external interference.

[0031] The positioning mechanism includes a positioning plate 5, a positioning bolt 52 and a positioning column 53. The positioning plate 5 is provided with a rotating rod 51, and the rotating rod 51 is rotatably provided on the welding fixing frame 2. The positioning bolt 52 passes through the positioning plate 5 and is connected to the welding fixing frame 2. The positioning plate 5 positions the first wing panel 11 and one side of the first wing panel 11, and the positioning column 53 is provided on the welding fixing frame 2 for abutting the first wing panel 11 and the other side of the second wing panel 41.

[0032] By adjusting the rotating rod 51 on the positioning plate 5, the positioning plate 5 is closely fitted with one side of the first wing plate 11 and the second wing plate 41. Tighten the positioning bolts 52 to firmly fix the positioning plate 5 on the first wing plate 11 and the second wing plate 41. At the same time, the positioning column 53 on the welding fixture 2 is used to abut the other side of the first wing plate 11 and the second wing plate 41 to further enhance the positioning effect. The first wing plate 11 and the second wing plate 41 of the short rocker body can be accurately positioned to ensure that the position is accurate during the welding process.

[0033] The limiting mechanism includes a limiting plate 6, a limiting bolt 62 and a limiting column 63. The limiting plate 6 is provided with a limiting rod 61, and the limiting rod 61 is rotatably provided on the welding fixing frame 2.

The limiting column 63 is fixedly provided on the welding fixing frame 2 and abuts against the other side of the mounting buckle 12.

[0034] First, place the rocker seat 1 of the short rocker body including the mounting buckle 12 on the predetermined position of the welding fixture 2. By adjusting the limiting rod 61 on the limiting plate 6, the limiting plate 6 and the mounting buckle 12 are tightly fitted on one side of the connection between the rocker seat 1 and the outer peripheral wall. Tighten the limiting bolt 62 so that the limiting plate 6 abuts against the connection between the mounting buckle 12 and the outer peripheral wall of the rocker seat 1.

[0036] The adjustment column 72 is arranged on the welding fixture 2, and forms an abutment relationship with the other side of the arc rod 3. It serves as the other end support point or limit point of the arc rod 3, and works together with the adjustment rod 71 to ensure the stability and accuracy of the arc rod 3 during the adjustment process. At the same time, during the welding process, the arc rod 3 can maintain a stable posture and position, avoiding errors caused by vibration or external interference.

[0037] A supporting mechanism is provided at the bottom of the rocker seat 1 and the rocker head 4, and the supporting mechanism includes a supporting column 8 and a first spring 82.

[0038] During the welding process, the rocker base 1 and the rocker head 4 are subjected to forces and moments from different directions. The support mechanism resists the influence of these forces and moments through the stable support of the support column 8 and the buffering and shock-absorbing effect of the first spring 82, ensuring that the rocker base 1 and the rocker head 4 can maintain a stable posture and position. At the same time, the design of the first anti-slip pattern 81 also enhances the friction between the support column 8 and the connecting part, preventing sliding or falling off.

[0040] During the welding process, when the rocker seat 1 is subjected to forces and moments from different directions, the abutment mechanism resists the influence of these forces and moments through the precise support of the abutment column 9 and the buffering and shock-absorbing effect of the second spring 92. The abutment column 9 directly supports the inclined part of the rocker seat 1 to prevent it from deformation or displacement; while the second spring 92 absorbs the impact force and vibration from the rocker seat 1 to protect the welding fixing frame 2 from damage. At the same time, the design of the second anti-slip pattern 91 also enhances the friction between the abutment column 9 and the rocker seat 1 to prevent sliding or falling off.

[0041] Working principle of the present invention: When welding the short rocker of a precision industrial robot, the first wing plate 11 and the second wing plate 41 are accurately locked by the positioning mechanism on the welding fixing frame 2 to ensure that the position of the short rocker body is correct. The limiting mechanism implements double limiting on both sides of the mounting buckle 12 to enhance stability. The adjustment mechanism flexibly adjusts the position of the arc rod 3 to maintain a stable posture during welding. At the same time, the support mechanism and the abutment mechanism respectively provide stable support and buffering shock absorption for the rocker seat 1 and the rocker head 4 through the combination of the support column 8 and the first spring 82, the abutment column 9 and the second spring 92, and the anti-slip pattern design, ensuring that the entire welding process is carried out smoothly and reducing errors and damage risks.

[0042] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
