The angle adjustment mechanism 60 includes two sliding shafts 63 installed on the outer area of ​​the rotating shaft roller 41 and the outer area of ​​the supporting column 30, two transmission wheels 61 slidably connected to the two sliding shafts 63, and a transmission belt 62 sleeved on the outside of the two transmission wheels 61;

[0033] A locking assembly 70 is installed on the outside of the support column 30, and the locking assembly 70 includes a positioning shaft 71 fixedly installed on the outer bottom of the support column 30, a first meshing tooth 74 arranged on the outer periphery of the positioning shaft 71, a second meshing tooth 73 installed on the inner side of the sliding shaft 63 at the bottom, and a positioning bolt 72 that passes through the sliding shaft 63 at the bottom. A thread matching the positioning bolt 72 is arranged at the outer center of the positioning shaft 71, and the positions of the first meshing tooth 74 and the second meshing tooth 73 correspond to each other.

[0034] It should also be noted that the electrical components of this device are all externally powered and electrically connected to a conventional PLC controller.

[0035] For details, please refer to the attached Figure 5The two transmission wheels 61 are both annular structures, and arc-shaped protrusions 611 are provided on both sides of the transmission wheel 61, and arc-shaped sliding grooves matching the arc-shaped protrusions 611 are provided on both sides of the two sliding shafts 63;

[0036] In this embodiment, it should be noted that the provision of the arc-shaped protrusion 611 and the arc-shaped sliding groove can prevent the relative rotation between the transmission wheel 61 and the sliding shaft 63, thereby making it impossible to smoothly adjust the rotation angle of the rotating shaft roller 41.

[0037] For details, please refer to the attached Figure 5 , both sides of the sliding shaft 63 are provided with limiting rings 64, and the transmission wheel 61 is located between the two limiting rings 64;

[0038] In this embodiment, it should be noted that the two limiting rings 64 can limit the movable distance of the transmission wheel 61 on the sliding shaft 63 to prevent the transmission wheel 61 from being separated from the sliding shaft 63 .

[0039] For details, please refer to the attached Figure 4 , three arc-shaped notches are arranged at equal distances on the side of the nut of the positioning bolt 72;

[0040] In this embodiment, it should be noted that the three arc-shaped notches facilitate buckling three fingers on the positioning bolt 72 to rotate the positioning bolt 72 .

[0041] For details, please refer to the attached Figure 2 Two sliding grooves 11 are installed on the top of the welding table 10, and a cavity is set between the two sliding grooves 11. The displacement mechanism 20 includes two ball screws 21 rotatably connected in the two sliding grooves 11, a nut seat 22 symmetrically installed on the two ball screws 21, and a driving motor 23 installed on the top of the cavity between the two sliding grooves 11. The two ball screws 21 both penetrate into the cavity, and a transmission bevel gear 24 is installed on the inner end of the two ball screws 21 and the output shaft of the driving motor 23, and the three transmission bevel gears 24 are meshed with each other;

[0042] In this embodiment, it should be noted that the three transmission bevel gears 24 can be driven by the operation of the driving motor 23, so that the two ball screws 21 rotate synchronously and in opposite directions, thereby achieving the two clamp assemblies 50 approaching or moving away from each other, thereby adapting to metal windows of different sizes.

[0043] For details, please refer to the attached Figure 3 The support column 30 is composed of a hollow fixed column 31 with an opening at the top and a sliding column 32 sliding inside the fixed column 31. A cylinder 80 is installed at the bottom of the fixed column 31, and the output rod of the cylinder 80 is connected to the bottom of the sliding column 32.

[0044] In this embodiment, it should be noted that the sliding column 32 can be raised and lowered by operating the cylinder 80, thereby adjusting the height of the clamp assembly 50, thereby facilitating subsequent welding operations and preventing the metal window from being too long and contacting the welding table 10 when flipping.

[0045] For details, please refer to the attached Figure 3 The clamp assembly 50 includes an L-shaped clamping plate 51 connected to the rotating shaft roller 41, a movable clamping plate 52 sliding inside the L-shaped clamping plate 51, and an adjusting bolt 53 installed on the top of the L-shaped clamping plate 51 and rotatably connected to the movable clamping plate 52;

[0046] In this embodiment, it should be noted that the movable clamping plate 52 can be raised and lowered by rotating the adjusting bolt 53 , and can then be used in conjunction with the L-shaped clamping plate 51 to clamp metal windows of different thicknesses.

[0047] For details, please refer to the attached Figure 3 The inner side of the movable splint 52 is provided with two empty slots, and a guide rod 54 is fixedly installed in the empty slot, and the movable splint 52 is located on the guide rod 54 and slides;

[0048] In this embodiment, it should be noted that the guide rod 54 can make the lifting and lowering of the movable clamping plate 52 more stable.

[0049] For details, please refer to the attached Figure 3 The L-shaped clamping plate 51 and the movable clamping plate 52 are both inlaid with anti-skid rubber pads 55 on the sides close to each other;

[0050] In this embodiment, it should be noted that the anti-slip rubber pad 55 can increase the friction resistance, so as to better fix the metal window.

[0051] Furthermore, a bearing is installed at the rotation connection between the mounting plate 40 and the rotating shaft roller 41;

[0052] It should be noted that the positioning shaft 71 and the positioning bolt 72 are fixedly connected.

[0053] The specific operation mode of the present invention is as follows:

[0054] First, the distance between the two clamp assemblies 50 is adjusted according to the size of the metal window to be welded. The three transmission bevel gears 24 can be driven by the operation of the driving motor 23, so that the two ball screws 21 rotate synchronously and in opposite directions, thereby realizing the two clamp assemblies 50 approaching or moving away from each other. Then, the metal window is placed on top of the two L-shaped clamps 51, and then the adjusting bolts 53 are screwed so that the movable clamp 52 and the L-shaped clamp 51 fix the metal window.

[0055] When the angle adjustment or flipping is required, first rotate the positioning bolt 72 toward the outside, then adjust the sliding positioning shaft 71 toward the outside to separate the first meshing tooth 74 and the second meshing tooth 73, and then rotate the positioning bolt 72 to allow the transmission wheel 61 and the transmission belt 62 to transmit, thereby driving the clamp assembly 50 to rotate through the rotating shaft roller 41 to complete the angle adjustment of the metal window.

[0056] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
