When welding the motor housing, the push button 10 can be pressed to allow the gas inside the sliding cavity of the push button 10 to enter the sliding cavity of the adjusting block 12 through the air guide tube 11, thereby allowing the adjusting block 12 to slide, driving the pushing fixing rod 13 to disengage from the side wall of the lifting block 3, thereby allowing the rotating rod 8 to be rotated. After the rotation is completed, the push button 10 is released, and the spring pushes the fixing rod 13 to contact the side wall of the lifting block 3, thereby fixing the rotating rod 8, thereby making it more convenient to rotate the motor housing when welding the motor housing.

[0025] like Figures 4 to 5As shown, a plurality of anti-deflection blocks 14 are fixedly connected to the side wall of the push button 10, and the anti-deflection blocks 14 are regularly arranged in a circular array on the side wall of the push button 10; an anti-deflection groove 15 is opened on the inner side wall of the rotating rod 8; the anti-deflection block 14 is slidably connected at the internal position of the anti-deflection groove 15; during operation, when the push button 10 slides inside the rotating rod 8, by arranging the anti-deflection block 14 on the side wall of the push button 10 and limiting the sliding of the anti-deflection block 14 by the anti-deflection groove 15, the push button 10 can be less likely to tilt when sliding, and the sliding of the push button 10 can be more stable.

[0026] like Figure 4 As shown, an anti-skid pad 16 is fixedly connected to the side wall of the pushing and fixing rod 13; the side wall of the anti-skid pad 16 is in contact with the side wall of the lifting block 3; during operation, when the pushing and fixing rod 13 is in contact with the side wall of the lifting block 3, by arranging the anti-skid pad 16 on the side wall of the pushing and fixing rod 13, the contact area between the pushing and fixing rod 13 and the side wall of the lifting block 3 can be made larger, so that the friction force between the pushing and fixing rod 13 and the side wall of the lifting block 3 can be made larger, so that the pushing and fixing rod 13 can fix the rotating rod 8 more stably.

[0027] like Figure 1 to Figure 2 As shown, a guide rod 17 is fixedly connected to the interior of the sliding frame 2; the guide rod 17 is arranged in parallel with the adjusting threaded rod 4; the lifting block 3 is slidably connected to the guide rod 17; a guide block 18 is fixedly connected to the side wall of the lifting block 3; the guide block 18 is slidably connected to the internal position of the sliding frame 2; during operation, when the lifting block 3 slides inside the sliding frame 2, the sliding of the lifting block 3 is restricted by the guide rod 17, and the sliding of the guide block 18 is restricted by the sliding frame 2, so that the lifting block 3 is less likely to tilt when sliding, and the lifting block 3 is more stable when sliding.

[0028] like Figure 3 As shown, a positioning block 19 is fixedly connected to the side wall of the driven block 7; the positioning block 19 is rotatably connected to the internal position of the push rod 6; during operation, when the motor housing contacts the end of the push rod 6, the motor housing will contact the side wall of the driven block 7, and when the motor housing rotates, the rotation of the driven block 7 can make the friction between the motor housing and the push rod 6 smaller, thereby reducing the wear between the motor housing and the push rod 6, and at the same time, the rotation of the positioning block 19 is restricted by the push rod 6, so that the driven block 7 can be more stable when rotating.

[0029] like Figure 3As shown, a plurality of anti-wear balls 20 are provided between the push rod 6 and the positioning block 19; the side walls of the anti-wear balls 20 are in contact with the side walls of the push rod 6 and the positioning block 19; during operation, when the positioning block 19 rotates inside the push rod 6, the sliding friction between the push rod 6 and the positioning block 19 is converted into rolling friction, so that the friction force between the push rod 6 and the positioning block 19 is smaller, thereby reducing the wear between the push rod 6 and the positioning block 19.

[0030] During operation, when it is necessary to weld the motor housing, the motor housing and the end cover can be placed on the two pushing blocks 5 respectively, and the heights of the two pushing blocks 5 can be adjusted. Then, the pushing rod 6 can be pushed by the electric cylinder, so that the pushing rod 6 and the driven block 7 push the motor housing. After the motor housing and the end cover are spliced, the rotation of the adjusting threaded rod 4 can be adjusted so that the adjusting threaded rod 4 and the thread of the lifting block 3 can be matched to drive the lifting block 3 to rise. After the lifting block 3 rises to a suitable position, the welding of the motor housing can be facilitated. During welding, the push button 10 can be pressed so that the gas inside the sliding cavity of the push button 10 enters the sliding cavity of the adjusting block 12 through the air guide tube 11, so that the adjusting block 12 can slide, driving the pushing fixing rod 13 to disengage from the side wall of the lifting block 3, so that the rotating rod 8 can be rotated. After the rotation is completed, the push button 10 is released, so that the spring pushes the fixing rod 13 to contact the side wall of the lifting block 3, thereby fixing the rotating rod 8, so that when the motor housing is welded, the rotation of the motor housing is more convenient.

[0031] When the push button 10 slides inside the rotating rod 8, by setting an anti-deflection block 14 on the side wall of the push button 10 and limiting the sliding of the anti-deflection block 14 through the anti-deflection groove 15, the push button 10 is less likely to tilt when sliding, making the sliding of the push button 10 more stable.

[0032] When the pushing and fixing rod 13 contacts the side wall of the lifting block 3, by arranging the anti-skid pad 16 on the side wall of the pushing and fixing rod 13, the contact area between the pushing and fixing rod 13 and the side wall of the lifting block 3 can be made larger, so that the friction force between the pushing and fixing rod 13 and the side wall of the lifting block 3 can be made larger, so that the pushing and fixing rod 13 can fix the rotating rod 8 more stably.

[0033] When the lifting block 3 slides inside the sliding frame 2, the sliding of the lifting block 3 is limited by the guide rod 17, and the sliding of the guide block 18 is limited by the sliding frame 2, so that the lifting block 3 is less likely to tilt when sliding, and the lifting block 3 is more stable when sliding.

[0034] When the motor housing contacts the end of the push rod 6, the motor housing will contact the side wall of the driven block 7. When the motor housing rotates, the rotation of the driven block 7 can reduce the friction between the motor housing and the push rod 6, thereby reducing the wear between the motor housing and the push rod 6. At the same time, the rotation of the positioning block 19 is restricted by the push rod 6, so that the driven block 7 can be more stable when rotating.

[0035] When the positioning block 19 rotates inside the push rod 6, the sliding friction between the push rod 6 and the positioning block 19 is converted into rolling friction, so that the friction force between the push rod 6 and the positioning block 19 is smaller, thereby reducing the wear between the push rod 6 and the positioning block 19.
