[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0030] Embodiment 1;

[0031] Refer to Figure 1-7 , an air conditioner stator welding and placing fixture, including a base 1, a clamping mechanism, a moving welding mechanism, and a demolding mechanism:

[0032] A support plate 8 is fixedly connected to the upper end of the base 1, a hydraulic cylinder 9 is installed on the upper end of the support plate 8, the piston end of the hydraulic cylinder 9 penetrates and is slidably connected to the support plate 8, and the piston end of the hydraulic cylinder 9 is fixedly connected to a pressing plate 10

[0033] The clamping mechanism is composed of a turntable 2, multiple piston cylinders 3, a top core 201, a receiving seat 202, and a mold 6. The turntable 2 is rotatably connected to the upper end of the base 1, multiple piston cylinders 3 are fixedly and evenly connected to the upper end of the turntable 2 at equal intervals, the top core 201 is fixedly connected to the upper end of the turntable 2, a piston rod 301 is slidably connected in each piston cylinder 3, a first spring 302 is arranged in the piston cylinder 3, the upper ends of multiple piston rods 301 are fixedly connected to the lower end of the receiving seat 202 together, the mold 6 is fixedly connected to the upper end of the receiving seat 202, the top core 201 penetrates and is slidably connected to the receiving seat 202, an orientation adjustment motor 401 is installed at the lower end of the inner wall of the base 1, the output shaft of the orientation adjustment motor 401 penetrates and is rotatably connected to the base 1, and the output shaft of the orientation adjustment motor 401 is fixedly connected to the turntable 2;

[0034] The demolding mechanism is used for demolding the stator;

[0035] The moving welding mechanism is used for welding the stator.

[0036] Multiple slots 601 are provided in the mold 6. A clamping plate 602 is slidably connected in each slot 601. A first abutting plate 604 is fixedly connected to the upper end of the clamping plate 602. A second abutting plate 603 is fixedly connected to the slot 601. A second spring 605 is fixedly connected to the side wall of the first abutting plate 604. One end of the second spring 605 away from the first abutting plate 604 is fixedly connected to the second abutting plate 603. An inclined angle is provided at the lower end of the clamping plate 602. A hole is provided in the mold 6. The top core 201 is slidably connected to the mold 6 through the hole. It should be noted that the upper end of the top core 201 is conical so as to be able to fit the inclined angle side of the clamping plate 602. It should be noted that the clamping plate 602 is made of copper, and a chamfer is provided on the abutting surface of the clamping plate 602. The number of the clamping plates 602 is set according to the number of slots inside the stator. The size of the mold 6 is changed according to the size of the stator welding. This is common knowledge in the art and will not be elaborated here.

[0037] In this embodiment, first, the air conditioner stator to be welded is placed on the mold 6. Subsequently, the orientation adjustment motor 401 is started to drive the turntable 2. The turntable 2 rotates on the upper end of the base 1, driving the piston cylinder 3, the top core 201, the receiving seat 202 and the mold 6 thereon to rotate. When the mold 6 rotates to a suitable position, the orientation adjustment motor 401 is stopped. The hydraulic cylinder 9 on the support plate 8 is started. The piston end of the hydraulic cylinder 9 extends downward, pushing the pressing plate 10 to move downward. While pressing the stator, the pressing plate 10 pushes the receiving seat 202 to move downward. At this time, the top core 201 contacts the inclined surface of the clamping plate 602. As the receiving seat 202 continues to move downward, the top core 201 generates a squeezing force on the inclined surface of the clamping plate 602, thereby pushing out the clamping plate 602. The clamping plate 602 moves outward and contacts the inner wall of the stator, clamping the stator. At this time, the second spring 605 is compressed. At the same time, the piston rod 301 in the piston cylinder 3 provides an upward supporting force to the receiving seat 202 under the reverse action of the first spring 302 to balance part of the acting force of the pressing plate 10 pressing downward, ensuring the stability of the entire clamping structure, ensuring the stable position of the stator during the welding process. At the same time, when the welding is completed, the hydraulic cylinder 9 resets. Under the condition of losing the external force suppression, the first spring 302 further drives the receiving seat 202 to reset. When the receiving seat 202 resets, the clamping plate 602 loses contact with the top core 201, and then the clamping plate 602 loses the external force restraint, and the second spring 605 is reset, thereby driving the clamping plate 602 to reset.

[0038] Embodiment Two:

[0039] Further refer to Figure 1-7, compared with the first embodiment, in this embodiment, the mobile welding mechanism is composed of a connecting plate 11, a mounting plate 14, a first motor 15, a first lead screw 1101, two sets of T-shaped sliders 12, and a sliding plate 13. The connecting plate 11 is fixedly connected to the upper end of the base 1, the mounting plate 14 is fixedly connected to the upper end of the connecting plate 11, the first motor 15 is installed on the upper end of the mounting plate 14, the two sets of T-shaped sliders 12 are symmetrically and fixedly connected to the side wall of the connecting plate 11, the two sets of T-shaped sliders 12 jointly slidably connect the sliding plate 13, the output shaft of the first motor 15 is fixedly connected to the first lead screw 1101, the first lead screw 1101 is rotatably connected to the mounting plate 14, the first lead screw 1101 passes through and is threadedly connected to the sliding plate 13, and the end of the first lead screw 1101 away from the first motor 15 is rotatably connected to the base 1. A chute 21 is provided in the sliding plate 13, a first baffle 17 is fixedly connected to the upper end of the sliding plate 13, a second baffle 19 is fixedly connected to the upper end of the sliding plate 13, a second motor 16 is installed on the side wall of the first baffle 17, a second lead screw 18 is rotatably connected to the side wall of the first baffle 17, the end of the second lead screw 18 away from the first baffle 17 is rotatably connected to the second baffle 19, the output shaft of the second motor 16 is fixedly connected to the second lead screw 18, the second lead screw 18 passes through and is threadedly connected to a lead screw sleeve 20, the lead screw sleeve 20 is slidably connected in the chute 21, a protective cover 101 is fixedly connected to the side wall of the lead screw sleeve 20, a welding head 102 is fixedly connected to the side wall of the lead screw sleeve 20, a grinding plate 103 is fixedly connected to the lower end of the lead screw sleeve 20. An air pump 22 is installed on the upper end of the base 1, an intake pipe 24 is fixedly connected to the intake port of the air pump 22, an outlet pipe 23 is fixedly connected to the outlet port of the air pump 22, an argon gas tank 26 is fixedly connected to the side wall of the base 1, an argon gas pipe 25 is fixedly connected to the upper end of the argon gas tank 26, and the end of the argon gas pipe 25 away from the argon gas tank 26 is fixedly connected to the protective cover 101, and the end of the intake pipe 24 away from the air pump 22 is fixedly connected to the protective cover 101. It should be noted that the end of the outlet pipe 23 away from the air pump 22 is connected to an exhaust gas collection and treatment device.

[0040] In this embodiment, the second motor 16 is started, and the second motor 16 drives the second lead screw 18 to rotate. The lead screw sleeve 20 threadedly connected to the second lead screw 18 slides in the chute 21, thereby adjusting the lateral position of the welding head 102 so that the welding head 102 is aligned with the welding part of the stator for welding. Subsequently, the first motor 15 is started, and the first motor 15 drives the first lead screw 1101 to rotate. Since the first lead screw 1101 is threadedly connected to the slide plate 13, and the slide plate 13 is slidably connected to the connecting plate 11 through two sets of T-shaped sliders 12, the slide plate 13 will move linearly along the direction of the T-shaped sliders 12. When the slide plate 13 descends, it will drive the welding head 102 to move downward. Since the grinding plate 103 is arranged below the welding head 102, the grinding plate 103 first contacts the stator to be welded, and the stator is first ground to facilitate welding by the welding head 102. The protective cover 101 prevents welding sparks from splashing. At the same time, before welding, the argon gas tank 26 is opened first, so that the high-pressure argon gas filled inside the argon gas tank 26 is transported to the inside of the protective cover 101 through the argon gas pipe 25, providing a protective gas environment for welding. At the same time, the air pump 22 is started, and the air pump 22 circulates the gas in the welding area through the suction pipe 24 and the discharge pipe 23, sucking away the waste gas generated by welding to avoid polluting the environment.

[0041] Embodiment Three:

[0042] Further referring to Figure 1-8 , compared with Embodiment Two, in this embodiment, the demolding mechanism is composed of a sleeve plate 4 for taking parts and four demolding cylinders 7. The sleeve plate 4 for taking parts is sleeved on the outer wall of the mold 6, and the sleeve plate 4 for taking parts is slidably connected to the mold 6. The four demolding cylinders 7 are fixedly connected to the inner wall of the base 1 at equal intervals. The four demolding cylinders 7 penetrate through the base 1. Four through slots 5 are opened on the sleeve plate 4 for taking parts. It should be noted that the through slots 5 opened on the sleeve plate 4 for taking parts are to avoid blocking the welding head 102 and the grinding plate 103. It should be noted that the height of the outer edge of the sleeve plate 4 for taking parts is higher than the height of the position for placing the stator inside, forming a height difference, so as to avoid the stator from tipping over due to possible vibrations during demolding.

[0043] In this embodiment, after welding is completed, the first motor 15 and the second motor 16 rotate in reverse, so that the slide plate 13 and the lead screw sleeve 20 return to their initial positions. Then, the demolding cylinder 7 is started, and its output rod pushes the sleeve plate 4 for taking parts to move upward. The sleeve plate 4 for taking parts is sleeved on the outer wall of the mold 6 and slides along it, pushing out the welded stator from the mold 6 to complete demolding.
