Description

Technical Field

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] Please see Figures 1-5 A full-welding fixture for a robot with upper, middle, and lower beams includes a main body 1, a running mechanism, and a fixing mechanism. The running mechanism includes a first moving mechanism and a second moving mechanism. The first moving mechanism includes an upper beam 2, a first motor 3, a transverse slider 4, a first lead screw 5, and a mounting frame 6. The upper beam 2 is fixedly mounted on the main body 1, the first motor 3 is fixedly mounted on the upper beam 2, the transverse slider 4 is installed inside the upper beam 2 and slidably connected to the upper beam 2, one end of the first lead screw 5 is fixedly mounted on the output end of the first motor 3, and the mounting frame 6 is fixedly mounted on the transverse slider 4. The second moving mechanism includes a second motor 7, a transmission belt 8, a rotating component 9, a second lead screw 10, a middle beam 11, and a welding component 12. The second motor 7 is fixedly mounted on the mounting frame 6, both ends of the transmission belt 8 are rotatably connected to the second motor 7 and the rotating component 9, respectively. The rotating component 9 is installed in the mounting frame 6 and rotatably connected to the mounting frame 6, the second lead screw 10 is respectively connected to the rotating component 9 and rotatably connected to the middle beam 11, the middle beam 11 is slidably connected to the mounting frame 6, and the welding component 12 is fixedly mounted on the middle beam 11.

[0031] In this embodiment, the operating mechanism includes a first moving mechanism and a second moving mechanism. The first moving mechanism includes an upper beam 2, a first motor 3, a transverse slider 4, a first lead screw 5, and a mounting bracket 6. In use, the first motor 3 drives the first lead screw 5 to rotate in the upper beam 2. Under the action of the first lead screw 5, the transverse slider 4 slides in the upper beam 2. In order to ensure the stable installation of the mounting bracket 6 and the stable sliding of the transverse slider 4, the first slider 25 on the transverse slider 4 slides in the first limiting groove 24 of the upper beam 2.

[0032] In this embodiment, the second moving mechanism includes a second motor 7, a transmission belt 8, a rotating component 9, a second lead screw 10, a central beam 11, and a welded component 12. The sliding of the mounting frame 6 causes the second moving mechanism to start operating. The second motor 7 on the mounting frame 6 starts to operate, causing the transmission belt 8 to rotate and driving the central rotating component 9 mounted on the mounting frame 6 to rotate. When the rotating component 9 rotates, the roller 22 on the mounting frame 6 also slides in the rotating groove 23 of the rotating component 9. The second lead screw 10, which is acted upon by the rotating component 9, directly drives the central beam 11 to slide up and down on the mounting frame 6, causing the longitudinal position of the welded component 12 on the central beam 11 to change. While the central beam 11 slides up and down, the second slider on the mounting frame 6 slides in the second limiting groove 26 of the central beam 11.

[0033] In this embodiment, the fixing mechanism includes a third motor 13, an electric push rod 14, a third lead screw 15, a sliding platform 16, and a clamping block 17. First, the workpiece to be welded is placed on the sliding platform 16. The electric push rod 14 is driven, directly causing the clamping block 17 to apply force to the workpiece, so that the workpiece can be fixed on the rubber pad 21 of the sliding platform 16. This increases friction while protecting any paint that may be on the workpiece. At this time, the third motor 13 is driven, and the third lead screw 15 begins to rotate inside the bearing 19. Under the action of the connecting piece 20, the sliding platform 16 slides on the main body 1. The fitting groove 29 on the sliding platform 16 is also slidably connected to the lower beam 28 installed on the main body 1, completing the stable sliding of the sliding platform 16 and allowing the position of the workpiece to be changed as required, which facilitates the welding of the workpiece.

[0034] Example 2:

[0035] In summary, during use, the workpiece to be welded is first placed on the sliding platform 16. The electric push rod 14 is then driven, directly causing the clamping block 17 to apply force to the workpiece, fixing it on the rubber pad 21 of the sliding platform 16. This increases friction while protecting any paint residue on the workpiece. At this time, the third motor 13 is driven, and the third lead screw 15 begins to rotate inside the bearing 19. Under the action of the connecting piece 20, the sliding platform 16 slides on the main body 1. The fitting groove 29 on the sliding platform 16 is also slidably connected to the lower beam 28 installed on the main body 1, completing the stable sliding of the sliding platform 16. This allows the position of the workpiece to be changed as required, facilitating welding. Once the workpiece is fixed, the position of the welding piece 12 can be adjusted, first by adjusting the lateral position. At this time, the first motor 3 is driven, directly causing the first lead screw 5 to rotate in the upper beam 2. Under the action of the first lead screw 5, the transverse slider 4 slides in the upper beam 2. In order to ensure the stable installation of the mounting frame 6 and the stable sliding of the transverse slider 4, the first slider 25 on the transverse slider 4 slides in the first limiting groove 24 of the upper beam 2. Then, the longitudinal position is adjusted. The second motor 7 on the mounting frame 6 starts to rotate, which causes the transmission belt 8 to rotate and drives the rotating component 9 on the mounting frame 6 to rotate. When the rotating component 9 rotates, the roller 22 on the mounting frame 6 also slides in the rotating groove 23 of the rotating component 9. The second lead screw 10, which is affected by the rotating component 9, directly drives the middle beam 11 to slide up and down on the mounting frame 6, so that the longitudinal position of the welded part 12 on the middle beam 11 changes. While the middle beam 11 slides up and down, the second slider on the mounting frame 6 slides in the second limiting groove 26 of the middle beam 11. When all the mechanisms are ready, the welding of the workpiece begins.

[0036] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
