[0033] The present application will be described in detail below in conjunction with the drawings and examples.

[0034] The present embodiment provides a rotary tool for welding ear plate joint, as shown in Figure 1 and Figure 2 , comprising: a center shaft 2, a rotary connecting seat 4, a rotary shaft 5, a base 6, two ear plate seats 1, a positioning pin 3, and a plurality of G-shaped clamps 7.

[0035] The longitudinal section of the base 6 is in the shape of an inverted T (i.e., the vertical part of the base 6 is on top and the horizontal part is on the bottom). The upper part of the base 6 is provided with a mounting hole a and a plurality of positioning holes a, the axis of the positioning hole a is parallel to the axis of the mounting hole a, and the plurality of positioning holes a are uniformly spaced along the circumference of the mounting hole a.

[0036] The rotating connector 4 is rotatably connected to the mounting hole a of the base 6 via a rotating shaft 5. Specifically, the rotating connector 4 is a U-shaped structure, comprising a horizontal portion and two vertical portions, with the open end of the U-shaped structure facing downward (i.e., the two vertical portions are at the bottom and the horizontal portion is at the top). Each vertical portion is provided with a mounting hole b, and the mounting holes b on the two vertical portions are coaxial. A positioning hole b is provided directly below the mounting hole b, and the axis of the positioning hole b is parallel to the axis of the mounting hole b.

[0037] The mounting hole b of the swivel connector 4 corresponds to the mounting hole a of the base 6, and the positioning hole b of the swivel connector 4 corresponds to the positioning hole a of the base 6. The rotating shaft 5 sequentially passes through the mounting hole b on one vertical portion of the U-shaped structure, the mounting hole a on the base 6, and the mounting hole b on the other vertical portion of the U-shaped structure, allowing the swivel connector 4 to rotate about the axis of the rotating shaft 5. When the swivel connector 4 rotates to a certain angle and the positioning holes b on its two vertical portions coincide with one of the positioning holes a, inserting the positioning pin 3 simultaneously into the positioning holes b and the positioning holes a can fix the swivel connector 4 at that angle, thereby locking the swivel connector 4 (i.e., maintaining the current rotation angle of the swivel connector 4).

[0038] The U-shaped horizontal portion of the connector 4 is provided with a lug at each end, positioned opposite each other and facing upward. Each lug is provided with a mounting hole c and a positioning hole c located directly above the mounting hole c. The two mounting holes c are coaxial, and the two positioning holes c are coaxial. The axis of the mounting hole c is parallel to the axis of the positioning hole c, and the axis of the mounting hole c is perpendicular to the axis of the mounting hole b. The central shaft 2 is coaxially mounted within the two mounting holes c of the rotatable connector 4. The central shaft 2 and the rotatable connector 4 are capable of relative rotation, allowing the central shaft 2 to rotate 360° around its axis.

[0039] The two ear plate seats 1 are symmetrically arranged at both ends of the central axis 2, and the two ear plate seats 1 can rotate with the central axis 2. The ear plate seat 1 includes: an L-shaped support 102 and a connecting rod 101, and the connecting rod 101 is fixedly connected to the L-shaped support 102 to form an F-shaped structure. The end of the connecting rod 101 away from the L-shaped support 102 is coaxially fixed to one end of the central axis 2. The ear plate joint 8 to be welded is an L-shaped structure, and the outer structure of the L-shaped support 102 matches the ear plate joint 8. The ear plate joint 8 to be welded is fixed to the L-shaped support 102 by a number of G-clips. The end of each connecting rod 101 fixed to the central axis 2 is coaxially sleeved with a positioning flange 103. The positioning flange 103 is provided with a number of positioning holes d, and the number of positioning holes d are evenly spaced along the circumference of the positioning flange 103, and the axis of the positioning hole d is parallel to the axis of the positioning flange 103.

[0040] like Figure 4As shown, when the ear plate seat 1 is provided with an ear plate seat 1 that rotates around its axis by a certain angle, the positioning holes d of the positioning flanges 103 on the same side coincide with the positioning holes c, and the positioning pins 3 are inserted into the positioning holes d and the positioning holes c at the same time, so that the ear plate seat 1 stops at the angle, realizing the locking of the ear plate seat 1. At this time, the positioning holes d of the positioning flanges 103 on the other side coincide with the positioning holes c, and the other positioning pins are inserted into the positioning holes d and the positioning holes c on the other side at the same time, realizing more stable locking.

[0041] Working principle:

[0042] The rotating tool can realize rotation in two perpendicular directions, thereby having high flexibility and adjustment ability to adapt to complex welding operations.

[0043] As Figure 3 shown, the rotating connection seat 4 of the rotating tool rotates around the axis of the rotating shaft 5; the height of the ear plate joint 8 on both sides of the ear plate seat 1 can be adjusted through the rotation of the rotating connection seat 4. Through the above height adjustment, the optimal relative position between the ear plate joint 8 and the welding tool can be ensured, thereby improving the welding quality and efficiency. The rotating position of the rotating connection seat 4 can be locked by the positioning pin 3, so that the ear plate joint 8 remains stable during welding.

[0044] As Figure 4 shown, the ear plate seat 1 of the rotating tool rotates 360° around the axis of the center shaft 2; the position of the ear plate joint 8 can be adjusted in all directions through the rotation of the ear plate seat 1, thereby meeting the needs of different welding positions, and further making the ear plate joint 8 can adapt to various different welding positions. The rotating position of the ear plate seat 1 can be locked by the positioning pin 3, so that the ear plate joint 8 remains stable during welding, further enhancing the stability and reliability of the welding process.

[0045] The rotating tool, through its precise adjustment mechanism and stable locking system, enables the ear plate joint 8 to rotate in two mutually perpendicular directions, not only improves the flexibility and efficiency of the welding operation, but also ensures the accuracy of the welding process and the high quality of the welded product. This design has a significant positive impact on improving production efficiency and ensuring product quality.

[0046] In summary, the above is only a preferred embodiment of the present application, and is not used to limit the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
