[0019] This application discloses a tooling fixture for welding metal frames. (Refer to...) Figure 1 , Figure 2 and Figure 3The metal frame welding fixture includes a base plate 1, a mounting plate 2 on the base plate 1, the mounting plate 2 being arranged perpendicular to the base plate 1, a drive assembly 3 on the base plate 1 for driving the mounting plate 2 to rise and fall, a fixed frame 4 connected to the mounting plate 2, a rotating motor 41 connected inside the fixed frame 4, a fixed bearing 42 connected to the fixed frame 4, a rotating shaft 43 connected inside the fixed bearing 42, the output shaft of the rotating motor 41 being coaxially connected to the rotating shaft 43 via a coupling, a fixed block 5 connected to the rotating shaft 43, the fixed block 5 being arranged perpendicular to the rotating shaft 43, a connecting frame 6 connected to the end of the fixed block 5, the connecting frame 6 being arranged in a "U" shape, and a clamping assembly 7 for clamping metal pipes on the connecting frame 6.
[0020] The drive assembly 3 includes a bearing housing 31, a first threaded rod 32, a nut seat 33, a column 34, a driving bevel gear 35, a driven bevel gear 36, and a drive motor 37. The bearing housing 31 is connected to the base plate 1. The first threaded rod 32 is connected to the bearing housing 31 and is arranged in a direction perpendicular to the base plate 1. The nut seat 33 is connected to the first threaded rod 32 and is connected to the mounting plate 2. The column 34 is connected to the base plate 1 and is arranged parallel to the first threaded rod 32. The column 34 has one on each side of the first threaded rod 32. The nut seat 33 has a through hole for the column 34 to pass through. The driven bevel gear 36 is connected to the first threaded rod 32 and is located at the end of the first threaded rod 32 near the bearing housing 31. The drive motor 37 is mounted on the base plate 1. The driving bevel gear 35 is connected to the output shaft of the drive motor 37, and the driving bevel gear 35 and the driven bevel gear 36 mesh with each other.
[0021] When adjusting the height of the metal tube, the drive motor 37 drives the active bevel gear 35 to rotate. The active bevel gear 35 and the driven bevel gear 36 work together to drive the first threaded rod 32 to rotate. Due to the guiding and limiting effect of the column 34, the nut seat 33 can move along the length direction of the first threaded rod 32, thereby driving the mounting plate 2 and the components on the mounting plate 2 to move, so as to adjust the height of the metal tube on the mounting plate 2.
[0022] A top plate 8 is connected to the column 34. The top plate 8 is located between the two columns 34 and at the top of the columns 34. A connecting bearing 81 is connected to the top plate 8. The top of the first threaded rod 32 is connected to the connecting bearing 81. By setting the top plate 8 and the connecting bearing 81 in conjunction with the bottom plate 1 and the bearing seat 31, the first threaded rod 32 and both ends of the column 34 can be fixed, which is beneficial to improving the structural stability of the drive assembly 3.
[0023] The clamping assembly 7 includes a clamping plate 71, a mounting bearing 72, a second threaded rod 73, a threaded sleeve 74, a turntable 75, and a guide rod 76. The mounting bearing 72 is connected to the connecting frame 6. The second threaded rod 73 is connected inside the mounting bearing 72. The turntable 75 is connected to the second threaded rod 73 and is located at the end of the second threaded rod 73 that does not penetrate into the connecting frame 6. The threaded sleeve 74 is threaded onto the rod body of the second threaded rod 73 that penetrates into the connecting frame 6. The end of the threaded sleeve 74 is connected to the clamping plate 71. The guide rod 76 is connected to the clamping plate 71 and is arranged parallel to the threaded sleeve 74. There is one guide rod 76 on each side of the threaded sleeve 74. The connecting frame 6 has guide holes for the guide rod 76 to pass through.
[0024] When clamping the metal tube, place the tube body between the connecting frame 6 and the clamping plate 71. Then, the operator manually rotates the turntable 75 and the second threaded rod 73. Due to the guiding and limiting effect of the guide rod 76, the threaded sleeve 74 can move along the length direction of the second threaded rod 73, thereby driving the clamping plate 71 to move closer to the metal tube. The clamping plate 71 cooperates with the connecting frame 6 to clamp and fix the metal tube.
[0025] A compression pad 711 is connected to the clamping plate 71. The compression pad 711 is located on the plate surface of the clamping plate 71 facing away from the threaded sleeve 74. The compression pad 711 helps to improve the clamping effect of the clamping plate 71 and the connecting frame 6 on the metal tube.
[0026] A fixing post 51 is connected to the fixing block 5. The fixing post 51 is set in a direction perpendicular to the fixing block 5. A guide roller 511 is connected to the fixing post 51. The guide roller 511 can roll on the fixing frame 4. By setting the fixing post 51 and the guide roller 511, the guide roller 511, which is set in the middle position of the fixing block 5, can roll on the fixing frame 4 to play a supporting role during the rotation of the fixing block 5, which helps to improve the stability of the fixing block 5 during the rotation process.
[0027] The implementation principle of a metal frame welding fixture according to an embodiment of this application is as follows: During operation, the operator places the metal pipe between the connecting frame 6 and the clamping plate 71. Then, the operator manually rotates the turntable 75 and the second threaded rod 73 to bring the clamping plate 71 closer to the metal pipe. The clamping plate 71, in conjunction with the connecting frame 6, clamps and fixes the metal pipe. Then, the drive motor 37 drives the active bevel gear 35 to rotate. Through the cooperation between the active bevel gear 35 and the driven bevel gear 36, the first threaded rod 32 is driven to rotate. Due to the guiding and limiting effect of the column 34, the nut seat 33 can move along the length direction of the first threaded rod 32, thereby driving the mounting plate 2 and the components on the mounting plate 2 to move, so as to adjust the metal pipe on the mounting plate 2 to a suitable height. Then, the rotating motor 41 drives the rotating shaft 43, the fixing block 5 and the connecting frame 6 to rotate, so that the metal pipe can rotate 360° to adjust to a suitable welding angle. This achieves the effect of improving the problem that the angle of the fixture itself cannot be adjusted, and improving its flexibility and practicality.
[0028] Finally, it should be noted that the above description is only a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model. It should be pointed out that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
