[0026] Furthermore, such as Figure 2 and Figure 4As shown, a universal clamping mechanism 3 is provided on the inner wall of the movable plate 114 and the surface of the adjusting clamp 116. The universal clamping mechanism 3 consists of a fixed groove 31, a movable rod 32, a guide groove 33, a fixed cylinder 34, and a third electric push rod 35. The inner wall of the movable plate 114 has a fixed groove 31, which slides with the surface of the adjusting clamp 116. The inner wall of the fixed groove 31 is fitted with a fixed cylinder 34, and the movable rod 32 is installed inside the fixed cylinder 34. One end of the movable rod 32 extends to the outside of the fixed cylinder 34 and is fixed to the surface of the adjusting clamp 116.

[0027] During implementation, the third electric push rod 35 inside the control fixed cylinder 34 is activated. Under the action of the third electric push rod 35, the moving rod 32 moves inside the fixed cylinder 34. Under the action of the guide groove 33, the moving rod 32 is guided, causing the moving rod 32 to drive the adjusting clamp 116 to slide inside the fixed groove 31. Under the action of the fixed groove 31, the adjusting clamp 116 is guided, causing the inner wall of the adjusting clamp 116 to move to contact the surfaces of the first frame 104 and the second frame 105 respectively. Under the combined action of the limiting clamp 115 and the adjusting clamp 116, the first frame 104 and the second frame 105 are clamped and fixed on the surfaces of the adjusting plate 110 and the support plate 109 respectively, so as to realize the function of the welding fixture to clamp and prevent displacement of the first frame 104 and the second frame 105 of different sizes.
[0028] Furthermore, such as Figure 2 and Figure 5 As shown, the adjustment plate 110 and the surface of the first frame 104 are provided with a precision positioning mechanism 4. The precision positioning mechanism 4 consists of a scale 41, a fastening screw 42, a positioning block 43, a rubber pad 44, a groove 45, and a slider 46. The surface of the adjustment plate 110 is provided with a positioning block 43 for positioning the first frame 104. A slider 46 is installed on the surface of the bottom position of the positioning block 43. The surface of the adjustment plate 110 is provided with a groove 45. The surface of the groove 45 and the surface of the slider 46 slide against each other. The surface of the positioning block 43 is threadedly connected with a fastening screw 42. One end of the fastening screw 42 passes through the positioning block 43 and is threadedly fastened to the inner wall of the groove 45. The surface of the positioning block 43 is provided with a rubber pad 44 for anti-slip of the first frame 104. The surface of the rubber pad 44 is in contact with the surface of the first frame 104. The surface of the adjustment plate 110 is provided with a scale 41.
[0029] During implementation, the user observes the scale 41 on the surface of the adjustment plate 110, then loosens the fastening screw 42 on the surface of the positioning block 43. The user pulls the positioning block 43, causing the slider 46 to slide inside the groove 45. Under the combined action of the groove 45 and the slider 46, the positioning block 43 is guided. After adjusting the positioning block 43 to the desired position, the user tightens the fastening screw 42 on the surface of the positioning block 43. Under the action of the fastening screw 42, the position of the positioning block 43 is fixed. The user then adjusts the position of the first frame 104 and the second frame 105, so that the first frame 104 moves to contact the surface of the rubber pad 44 on the surface of the positioning block 43. Under the action of the positioning block 43, the position of the first frame 104 is positioned. Under the action of the rubber pad 44, the first frame 104 is prevented from sliding on the surface of the adjustment plate 110, so as to achieve the function of precise positioning of the first frame 104 by the welding fixture.
[0030] Furthermore, such as Figure 2 and Figure 6 As shown, a rotary machining mechanism 2 is provided inside the fixture frame 1 and on the surface of the rotary table 102. The rotary machining mechanism 2 consists of a rotary motor 21, a holding groove 22, a belt body 23, a driven pulley 24, and a driving pulley 25. The fixture frame 1 has a holding groove 22 inside, and a driving pulley 25 is installed inside the holding groove 22. The driving pulley 25 rotates with the inner wall of the holding groove 22. The holding groove 22 also has a driven pulley 24 inside, which rotates with the inner wall of the holding groove 22. The surface of the pulley 25 is fitted with a belt body 23. The inner wall of the clamp frame 1 is equipped with a rotary motor 21, which can be of the JO series. The input end of the rotary motor 21 is electrically connected to the output end of the controller 103. One side of the rotary motor 21 extends into the interior of the holding tank 22. The output end of the rotary motor 21 is equipped with a rotating shaft through a coupling, and one end of the rotating shaft is fixed to the surface at the center position of the drive pulley 25. One end of the rotary table 102 extends into the interior of the holding tank 22 and is fixed to the surface at the center position of the driven pulley 24.
[0031] During implementation, the control motor 21 operates, driving the drive pulley 25 to rotate on the inner wall of the holding tank 22. When the drive pulley 25 rotates, it drives the belt body 23 to rotate, which in turn drives the driven pulley 24 to rotate on the inner wall of the holding tank 22. When the driven pulley 24 rotates, it drives the rotary table 102 to rotate on the inner wall of the fixture frame 1 and the mounting frame 101, thereby adjusting the welding angles of the first frame 104 and the second frame 105 on the surface of the rotary table 102. This allows the welding assembly to weld the first frame 104 and the second frame 105 at different angles, thus realizing the function of rotary processing of the welding fixture.
[0032] Working principle: In use, first place the fixture frame 1 and mounting bracket 101 in the designated position, tighten the mounting studs 106 on the surface of the fixture frame 1 and mounting bracket 101, and install the fixture frame 1 and mounting bracket 101 in the required position. The user adjusts the position of the adjusting plate 110 according to the dimensions of the first frame 104 and the second frame 105 to be welded. The user operates the controller 103, which controls the second electric push rod 111 on the inner wall of the groove 112 to work. Under the action of the second electric push rod 111, the adjusting plate 110 is driven to slide on the surface of the rotary table 102 to adjust the adjusting plate 110 to the required position. Then, the user places the first frame 104 and the second frame 105 to be welded on the surface of the support plate 109 and the adjusting plate 110 above the rotary table 102, respectively. The user observes the scale 41 on the surface of the adjusting plate 110, and then loosens the fastening screws 42 on the surface of the positioning block 43. The user pulls the positioning block 43. This causes the positioning block 43 to slide the slider 46 inside the groove 45. Under the combined action of the groove 45 and the slider 46, the positioning block 43 is guided. After adjusting the positioning block 43 to the desired position, the user tightens the fastening screw 42 on the surface of the positioning block 43. Under the action of the fastening screw 42, the position of the positioning block 43 is fixed. The user then adjusts the position of the first frame 104 and the second frame 105 so that the first frame 104 moves to contact the surface of the rubber pad 44 on the surface of the positioning block 43. Under the action of the positioning block 43, the position of the first frame 104 is positioned. Under the action of the rubber pad 44, the first frame 104 is prevented from sliding on the surface of the adjusting plate 110, so as to achieve the function of precise positioning of the first frame 104 by the welding fixture. Thus, when the welding fixture is used, the first frame 104 and the second frame 105 can be accurately placed on the surface of the support plate 109 and the adjusting plate 110, so that the accuracy of the welding fixture is higher.
[0033] Subsequently, the user operates the controller 103 on the surface of the mounting bracket 101, causing the controller 103 to control the first electric push rod 108 on the surfaces of the first L-shaped bracket 107 and the second L-shaped bracket 113. Under the action of the first electric push rod 108, the moving plate 114, the limiting clamp 115, and the adjusting clamp 116 move downwards to the desired position. The inner wall of the limiting clamp 115 contacts the surfaces of the first frame 104 and the second frame 105 respectively. The controller 103 controls the third electric push rod 35 inside the fixed cylinder 34 to operate. Under the action of the third electric push rod 35, the moving rod 32 moves inside the fixed cylinder 34. Under the action of the guide groove 33, the moving rod 32 is guided, causing the moving rod 32 to move the adjusting clamp 116. The fixed groove 31 slides inside, guiding the adjusting clamp 116 under the action of the fixed groove 31, so that the inner wall of the adjusting clamp 116 moves to contact the surface of the first frame 104 and the second frame 105 respectively. Under the combined action of the limiting clamp 115 and the adjusting clamp 116, the first frame 104 and the second frame 105 are clamped and fixed on the surface of the adjusting plate 110 and the support plate 109 respectively, so as to realize the function of the welding fixture to clamp and prevent displacement of the first frame 104 and the second frame 105 of different sizes. Thus, when the welding fixture is used, it can stably clamp and limit the first frame 104 and the second frame 105 of different sizes on the surface of the support plate 109 and the adjusting plate 110, making the welding fixture more versatile in use.
[0034] Subsequently, external welding components are used to weld the surfaces of the first frame 104 and the second frame 105. These welding components are not shown in the diagram. If the user needs to adjust the angle of the turntable 102, the controller 103 controls the rotation motor 21 to operate. Under the action of the rotation motor 21, the drive pulley 25 rotates on the inner wall of the holding tank 22. When the drive pulley 25 rotates, it drives the belt body 23 to rotate. Under the action of the belt body 23, the driven pulley 24 rotates on the inner wall of the holding tank 22. When the driven pulley 24 rotates... When in motion, the driven pulley 24 drives the rotary table 102 to rotate on the inner wall of the fixture frame 1 and the mounting frame 101, thereby adjusting the welding angle of the first frame 104 and the second frame 105 on the surface of the rotary table 102. This allows the welding assembly to weld the first frame 104 and the second frame 105 at different angles, thus realizing the function of rotary processing of the welding fixture. This allows the angle of the rotary table 102 to be adjusted according to the processing needs when using the welding fixture, making the welding fixture more convenient to operate and ultimately completing the use of the welding fixture.
