Detailed implementation manner

[0019] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment:

[0021] Please refer to Figures 1 - 3 , the present invention provides a technical solution:

[0022] A welding driving device includes a mounting seat main body 1. A connection groove 2 is opened at the top of the mounting seat main body 1. Two groups of clamping plates 3 are slidably connected inside the connection groove 2. The clamping plates 3 penetrate through the connection groove 2 and extend into the mounting seat main body 1 and are provided with two groups of connecting rods 4. The connecting rods 4 are connected to the mounting seat main body 1 through a driving assembly 5;

[0023] The driving assembly 5 is used to drive the connecting rod 4 to drive the clamping plate 3 to displace.

[0024] Further, the driving assembly 5 is composed of a moving frame 6, a connecting frame 7, a connecting block 8, a rotating rod 9, a moving block 10 and a fixed block 11. Two groups of moving frames 6 are both slidably connected inside the mounting seat main body 1. The connecting frame 7 is located outside the moving frame 6. The connecting block 8 is located outside the connecting frame 7. The rotating rod 9 is rotatably connected to one end of the connecting block 8 away from the connecting frame 7. The moving block 10 is located at one end of the two rotating rods 9 away from the connecting block 8. Multiple groups of fixed blocks 11 are all located at one end of the two moving frames 6 away from each other. When welding a welding part, place the welding part inside the connection groove 2 and contact the two groups of clamping plates 3. Drive the connecting rod 4 to displace through the driving assembly 5, so that the clamping plates 3 can displace and contact the welding part to limit and clamp the welding part, preventing the welding part from shifting during welding, which may affect the welding effect. And through the design of the driving assembly 5, only one telescopic cylinder can drive the two groups of clamping plates 3 to displace, thereby reducing costs. The structure design is ingenious and the practicability is strong.

[0025] Among them, the rotating rod 9 is rotatably connected to the moving block 10. One end of the moving block 10 away from the rotating rod 9 is fixedly connected to the driving end of the telescopic cylinder. One end of the telescopic cylinder away from the moving block 10 is provided with a fixing frame 12. The two ends of the fixing frame 12 are respectively fixedly connected to the fixing blocks 11. The rotating rod 9 and the moving block 10 are rotatably connected. The telescopic cylinder is started to drive the moving block 10 to displace, so that the two groups of rotating rods 9 can displace, drive the connecting block 8 to displace, so that the moving frame 6 can displace, drive the connecting rod 4 to displace, and thus the clamping plate 3 can displace. The fixing frame 12 and the fixing blocks 11 are fixedly connected. The fixing frame 12 is installed through the fixing blocks 11, so that the fixing frame 12 can fix the telescopic cylinder and prevent the telescopic cylinder from loosening during operation, resulting in affecting the displacement of the moving block 10.

[0026] Secondly, one end of the moving frame 6 close to the fixing block 11 is provided with a sliding rod 13. A sliding groove is opened inside the fixing block 11. The internal structure size of the sliding groove corresponds to the external structure size of the sliding rod 13. The sliding rod 13 is connected to the fixing block 11 through the sliding groove. The sliding rod 13 and the sliding groove are slidably connected, so that the sliding rod 13 can be slidably connected to the fixing block 11, and thus the moving frame 6 can be connected to the fixing block 11. When the moving frame 6 displaces and drives the sliding rod 13 to displace, the fixing block 11 and the sliding groove can guide the sliding rod 13, so that the stability of the displacement of the moving frame 6 can be increased and offset can be prevented.

[0027] Furthermore, one end of the moving frame 6 close to the fixing block 11 is rotatably connected to a first guiding rod 14. One end of the first guiding rod 14 away from the moving frame 6 is rotatably connected to a second guiding rod 15. One end of the second guiding rod 15 away from the first guiding rod 14 is rotatably connected to the fixing block 11. The second guiding rod 15 and the fixing block 11 are rotatably connected, so that the first guiding rod 14 can be connected to the fixing block 11 through the second guiding rod 15. When the moving frame 6 displaces, it drives the first guiding rod 14 to displace, so that the second guiding rod 15 can displace, and the fixing block 11 is used to guide the moving frame 6 to prevent offset.

[0028] Furthermore, a guiding groove 16 is opened inside the connecting groove 2. The internal structure size of the guiding groove 16 corresponds to the external structure size of the connecting rod 4. The connecting rod 4 is connected to the connecting groove 2 through the guiding groove 16. The connecting rod 4 and the guiding groove 16 are slidably connected, so that the connecting rod 4 can be fixedly connected to the moving frame 6 through the guiding groove 16. When the moving frame 6 displaces, the clamping plate 3 can be driven to displace through the connecting rod 4.

[0029] Further, limiting grooves 17 are formed at one ends of the two groups of clamping plates 3 close to each other, and limiting blocks 18 are arranged outside the limiting grooves 17. When the clamping plates 3 contact the welded parts, through the cooperation of the limiting grooves 17 and the limiting blocks 18 on the outside thereof, the welded parts can be limited and clamped, preventing the welded parts from shifting and affecting the welding effect.

[0030] In this embodiment, the implementation scenario is specifically as follows: During actual use, the telescopic cylinder is started to drive the moving block 10 to displace, so that the two groups of rotating rods 9 can displace, drive the connecting block 8 to displace, thereby enabling the moving frame 6 to displace, drive the connecting rod 4 to displace, and thus enabling the clamping plate 3 to displace and contact the welded part. When the clamping plate 3 contacts the welded part, through the cooperation of the limiting grooves 17 and the limiting blocks 18 on the outside thereof, the welded part can be limited and clamped, preventing the welded part from shifting and affecting the welding effect. When the moving frame 6 displaces to drive the sliding rod 13 to displace, the sliding rod 13 can be guided by the fixing block 11 in cooperation with the sliding groove, enabling the stability of the displacement of the moving frame 6 to be increased and preventing deviation. When the moving frame 6 displaces, it drives the first guide rod 14 to displace, enabling the second guide rod 15 to displace, and cooperating with the fixing block 11 to guide the moving frame 6 and prevent deviation. Compared with the existing driving device, the overall practicability of the driving device can be improved by the design of the present utility model.

[0031] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
