[0031] Please refer to Figure 1 - Figure 4, A welding auxiliary positioning device for a washing machine door frame, including a positioning ring 1. A sliding rod 101 penetrates and connects to the outer surface of the positioning ring 1. One end of the sliding rod 101 is fixedly connected to a clamping plate 102, and the other end of the sliding rod 101 abuts against a variable-diameter pipe 103. The end of the sliding rod 101 away from the clamping plate 102 penetrates and connects to a limiting ring 104. A groove 105 is provided on the outer surface of the positioning ring 1. A spring 106 is fixedly connected to the inner wall of the groove 105, and the other end of the spring 106 is fixedly connected to a T-shaped slider 107. The vertical end of the T-shaped slider 107 is fixedly connected to a sliding ring 108, and the sliding ring 108 is slidably connected to the outer surface of the positioning ring 1. A number of clamping grooves 109 are provided on the outer surface of the positioning ring 1 near the groove 105.

[0032] When fixing the washing machine door frame, first pull the variable-diameter pipe 103, and then pull the airbag 301 to change the air pressure inside the suction cup 202, so that the suction cup 202 is fixed to the washing machine. After the fixation is completed, continue to pull the variable-diameter pipe 103. During the pulling process, the variable-diameter pipe 103 drives the sliding rod 101 to slide, and the clamping plate 102 squeezes and fixes the washing machine door frame. After the fixation, then slide the sliding ring 108 to make it squeeze against the washing machine door frame. After the squeezing is completed, rotate the sliding ring 108 counterclockwise so that the T-shaped slider 107 fixed to the sliding ring 108 engages with the clamping groove 109 to fix the sliding ring 108, thereby realizing the fixation and positioning of the washing machine door frame, and then weld along the welding groove 4.

[0033] A fixing ring 2 is fixedly connected to the positioning ring 1 away from the sliding ring 108. An opening groove 201 is provided on the outer surface of the fixing ring 2, and a suction cup 202 is fixedly connected to the inner wall of the opening groove 201.

[0034] The fixing ring 2 fixedly connected to the positioning ring 1 away from the sliding ring 108 cooperates with the sliding ring 108 to realize the fixation and positioning of the washing machine door frame. The opening groove 201 provided on the outer surface of the fixing ring 2 is used to fix the suction cup 202, and the suction cup 202 fixedly connected to the inner wall of the opening groove 201 is used to connect the fixing ring 2 to the washing machine.

[0035] A gas transmission pipe 3 is communicated with the surface of the suction cup 202 close to the fixing ring 2. The other end of the gas transmission pipe 3 is communicated with an airbag 301, and the surface of the airbag 301 close to the limiting ring 104 is fixedly connected to the variable-diameter pipe 103.

[0036] The gas transmission pipe 3 communicated with the surface of the suction cup 202 close to the fixing ring 2 is used to discharge the gas inside the suction cup 202 to the airbag 301, so that the suction cup 202 is fixed to the washing machine. When fixing, slide the variable-diameter pipe 103, the internal space of the airbag 301 becomes larger to form a negative pressure. During the negative pressure process, the air inside the suction cup 202 is discharged to the airbag 301 through the gas transmission pipe 3, and the inside of the suction cup 202 becomes vacuum and is fixed to the washing machine.

[0037] The slip ring 108 is provided with a welding groove 4 near the surface of the fixed ring 2, and the welding groove 4 is located between the clamping plate 102 and the slip ring 108.

[0038] The welding groove 4 provided on the slip ring 108 near the surface of the fixed ring 2 is used for welding the washing machine door frame. During welding, the welding device is welded along the welding groove, so that no deviation occurs during the welding process.

[0039] The clamping plate 102 is arc-shaped and annularly arranged on the outer surface of the positioning ring 1, and the clamping plate 102 is located between the slip ring 108 and the fixed ring 2.

[0040] The clamping plate 102 is arc-shaped and annularly arranged on the outer surface of the positioning ring 1 so as to squeeze and fix the ring-shaped washing machine door frame.

[0041] The horizontal end of the T-shaped slider 107 is engaged with the card slot 109, the vertical end is fixedly connected to the slip ring 108, and both ends of the spring 106 are fixedly connected to the T-shaped slider 107 and the fixed ring 2 respectively.

[0042] The horizontal end of the T-shaped slider 107 is engaged with the card slot 109, and the vertical end is fixedly connected to the slip ring 108, which can fix the slip ring 108 and make the slip ring 108 stop sliding. Both ends of the spring 106 are fixedly connected to the T-shaped slider 107 and the fixed ring 2 respectively so that the slip ring 108 can be reset. When the T-shaped slider 107 is no longer engaged with the card slot 109, the compressed spring 106 squeezes the T-shaped slider 107 and the slip ring 108 to reset due to its elastic force.

[0043] The using process of a welding auxiliary positioning device for a washing machine door frame provided by the present utility model is as follows:

[0044] When fixing the washing machine door frame, the variable diameter pipe 103 can be pulled first, and then the air bag 301 is pulled to change the air pressure inside the suction cup 202, so that the suction cup 202 is fixed to the washing machine. After the fixing is completed, the variable diameter pipe 103 is continuously pulled. During the pulling process, the variable diameter pipe 103 drives the sliding rod 101 to slide, and the clamping plate 102 squeezes and fixes the washing machine door frame. After the fixing, the slip ring 108 is then slid to make it squeeze the washing machine door frame. After the squeezing is completed, the slip ring 108 is rotated counterclockwise so that the T-shaped slider 107 fixed to the slip ring 108 is engaged with the card slot 109 to fix the slip ring 108, thereby realizing the fixing and positioning of the washing machine door frame, and then welding is performed along the welding groove 4.
