Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1: Reference Figure 1-Figure 7 As shown: a tooling fixture for welding a condenser pipe of an automobile air conditioner, comprising a base 3, a reinforcement frame 4 is fixedly connected to the top of the base 3, a limiting mechanism 1 is arranged on the top of the reinforcement frame 4, the limiting mechanism 1 comprises a hydraulic cylinder 11, a limiting strip 13 and a positioning strip 17, a horizontal plate 14 is fixedly connected to the bottom of the hydraulic cylinder 11, an auxiliary frame 12 is fixedly connected to one side of the horizontal plate 14, a placement plate 2 is fixedly connected to the bottom of the auxiliary frame 12, the top of the placement plate 2 is engaged with the limiting strip 13, a pressure sensor 16 is embedded in the top of the placement plate 2, and a pressure sensor 16 is embedded in the top of the placement plate 2. A detection block 171 is overlapped on the top of the force sensor 16, and one side of the detection block 171 is fixedly connected to the positioning bar 17. An arc groove is provided at the bottom of the positioning bar 17. A spring buffer rod 19 is fixedly connected to the top of the positioning bar 17, and one side of the spring buffer rod 19 is fixedly connected to an extension block 191, and one side of the extension block 191 is fixedly connected to a connecting plate 18. The top of the connecting plate 18 is fixedly connected to one end of the hydraulic cylinder 11, and one side of the extension block 191 is slidably connected to a guide rail 15, and one side of the guide rail 15 is fixedly connected to the auxiliary frame 12.

[0023] In this example, the limiting strip 13 can be used to assist in the initial placement of the condenser tube on the top of the placement plate 2, which can reduce the positional deviation of the subsequent condenser tube during limiting. The placement plate 2 can be used to support and reinforce the bottom of the auxiliary frame 12. The cross plate 14 can be used to achieve the connection between the two auxiliary frames 12, which is convenient for improving the stability of the auxiliary frame 12 when it is installed and used on the top of the placement plate 2. At the same time, the cross plate 14 can be used to support the hydraulic cylinder 11. The bottom of the hydraulic cylinder 11 passes through the cross plate 14 and is fixedly connected to the connecting plate 18, which can reduce the interference of the cross plate 14 when the hydraulic cylinder 11 is in use. Both sides of the connecting plate 18 are fixedly connected to the spring buffer rods 19, which can achieve synchronization when the spring buffer rods 19 on both sides are raised and lowered. The connection between the spring buffer rods 19 and the connecting plate 18 can be achieved through the extension block 191. , thereby achieving consistency in the lifting and lowering of the connecting plate 18 and the spring buffer rod 19, and the guide rail 15 can guide the lifting and lowering of the extension block 191, thereby improving the stability of the spring buffer rod 19 and the positioning bar 17 during lifting and lowering, and the spring buffer rod 19 can buffer and protect the top of the positioning bar 17, and the positioning bar 17 can be connected to the detection blocks 171 on both sides.

An arc groove is provided at the bottom of the positioning bar 17, and the contact area between the two positioning bars 17 and the condenser is large, which has a good limiting effect on the pipeline, can reduce the displacement of the top of the placement plate 2 during pipeline welding, and thus can improve the stability of the pipeline during welding.

[0024] Embodiment 2: According to Figure 1-Figure 7 As shown, a motor 22 is fixedly connected to one side of the placement plate 2, and a lead screw 23 is fixedly connected to one end of the output shaft of the motor 22, and one end of the lead screw 23 is rotatably connected to the placement plate 2. A guide groove is provided at the top of the placement plate 2, and a push plate 21 is slidably connected in the guide groove. The push plate 21 and the lead screw 23 are threadedly connected, and a switching disk 44 is fixedly connected to the bottom of the placement plate 2. The top of the switching disk 44 is fixedly connected to the motor 22, and the bottom of the switching disk 44 is transmission-connected to a reduction box 41, and the bottom of the reduction box 41 is fixedly connected to the reinforcement frame 4, and a pulley assembly 43 is installed on one side of the input shaft of the reduction box 41, and the belt of the pulley assembly 43 passes through the reinforcement frame 4, and one side of one of the pulleys of the pulley assembly 43 is fixedly connected to the output shaft of the motor 2 42, and the bottom of the motor 2 42 is fixedly connected to the base 3.

[0025] In this embodiment, the placement plate 2 can be used to assist in the placement of multiple groups of condenser tubes. At the same time, the placement plate 2 can be used to support and reinforce one side of the motor 22. The switching disk 44 can also be used to support the bottom of the motor 22, so as to facilitate the stable installation and use of the motor 22 on the switching disk 44, improve the stability of the motor 22 when in use, and facilitate the motor 22 to drive the lead screw 23 to rotate stably. The lead screw 23 can be used to drive the position adjustment of the push plate 21. When the push plate 21 moves, the guide groove can guide the movement of the push plate 21, thereby reducing the position deviation of the push plate 21 when it moves. The push plate 21 applies a force to the condenser tube to push the condenser tube to slide on the top of the limit strip 13. The separation of the condenser tube from the limit strip 13 is accelerated, thereby facilitating the quick removal of the condenser tube from above the placement plate 2. The bottom of the reinforcement frame 4 can be supported and reinforced by the base 3. At the same time, the belt of the pulley assembly 43 passes through the top of the reinforcement frame 4, which can reduce the movement interference of the reinforcement frame 4 when the belt is in use. The motor 2 42 can provide power for the operation of the pulley assembly 43. The pulley assembly 43 can realize the connection between the motor 2 42 and the reduction box 41, thereby assisting the motor 2 42 in driving the reduction box 41 to operate. The reduction box 41 can be used to realize the rotation of the switching disk 44, thereby changing the processing stations of multiple condenser tubes, realizing station switching, and improving the processing efficiency of the condenser tube during welding.

[0026] Embodiment 3: According to Figure 1-Figure 5 As shown, a fixed plate 45 is fixedly connected to one side of the reinforcement frame 4, one end of a hydraulic push rod 5 is fixedly connected to one side of the fixed plate 45, the bottom of the hydraulic push rod 5 is fixedly connected to the base 3, a cooling mechanism 6 is arranged on one side of the hydraulic push rod 5, the cooling mechanism 6 comprises a reinforcement support seat 61, a fan 63 and a cooling pipe 64, one side of the reinforcement support seat 61 is fixedly connected to one end of the hydraulic push rod 5, and the bottom of the reinforcement support seat 61 is slidably connected to the base 3, a reinforcement plate 62 is slidably connected to the top of the reinforcement support seat 61, a hydraulic push rod 2 65 is fixedly connected to the bottom of the reinforcement plate 62, the bottom of the hydraulic push rod 2 65 is embedded in the reinforcement support seat 61, the top of the reinforcement plate 62 is fixedly connected to the fan 63, a cooling plate 66 is fixedly connected to one side of the reinforcement plate 62, the top of the cooling plate 66 is overlapped with the bottom of the placement plate 2, a cooling pipe 64 is embedded in the cooling plate 66, and one end of the cooling pipe 64 passes through the side wall of the cooling plate 66.

[0027] In this embodiment, the reinforcement frame 4 can be used to support the bottom of the fixed plate 45, which is convenient for improving the stability of the fixed plate 45 during installation and use. The connection between the reinforcement frame 4 and the hydraulic push rod 1 5 can be realized through the fixed plate 45. The hydraulic push rod 1 5 is stably installed on the top of the base 3, which is convenient for driving the reinforcement support seat 61 to slide stably on the top of the base 3, thereby changing the distance between the reinforcement support seat 61 and the fixed plate 45, controlling the approach or distance between the reinforcement plate 62 and the switching disk 44, and using the reinforcement support seat 61 to guide the lifting of the reinforcement plate 62. The hydraulic push rod 2 65 can provide power for the lifting of the reinforcement plate 62. The reinforcement plate 62 is fixedly connected to the cooling plate 66. When the cooling plate 66 is raised or lowered, the cooling plate 66 can keep in sync with the reinforcing plate 62, so that when the cooling plate 66 moves up with the reinforcing plate 62, its top is connected to the bottom of the placement plate 2, and the two ends of the cooling pipe 64 are respectively connected to the water pump and the water tank, so that the water can circulate quickly between the cooling pipe 64 and the water tank, and the heat exchange on the surface of the cooling plate 66 can be accelerated, so as to realize the cooling of the bottom of the placement plate 2. By cooling the placement plate 2, the heat dissipation protection of the condenser can be indirectly realized. The bottom support of the fan 63 can be reinforced by the reinforcing plate 62, and the air flow around the placement plate 2 and the condenser can be accelerated by the fan 63, so as to shorten the cooling time of the condenser and avoid burns when the condenser is taken out later.

[0028] The method of use and working principle of this device are as follows: first, the condenser tube to be welded is clamped on the limit strip 13, and then the hydraulic cylinder 11 drives the connecting plate 18 to move downward, and the spring buffer rods 19 on both sides of the connecting plate 18 drive the positioning strip 17 to move downward, and the bottom of the positioning strip 17 is pressed and limited with the condenser tube, and the bottom of the detection block 171 contacts with the pressure sensor 16 to detect the pressure of the positioning strip 17 on the pipeline, and the detection result is sent to the external control terminal. If the predetermined value is reached, the external control terminal is used to stop the hydraulic cylinder 11 from continuing to pressurize, and the pipeline is limited on the three placement plates 2 in turn, and then the motor 2 42 is used to drive one of the pulleys of the pulley assembly 43 to rotate, and under the transmission of the belt, the other pulley rotates, driving the gear inside the reduction box 41 to rotate, and then driving the switching disk 44 to rotate on the top of the reduction box 41, so as to realize the adjustment of the pipeline processing station, and move the pipeline to the vicinity of the welding equipment for welding processing; After welding is completed, the switching disk 44 continues to rotate and moves the pipeline to the vicinity of the cooling mechanism 6. At this time, the hydraulic push rod 1 5 drives the cooling mechanism 6 to move to the side close to the outer ring surface of the switching disk 44, and the hydraulic push rod 2 65 drives the reinforcement plate 62 and the cooling plate 66 to move upward, so that the top of the cooling plate 66 overlaps with the bottom of the placement plate 2. The two ends of the cooling pipe 64 are respectively connected to an external water pump and a water tank. The water pump accelerates the circulation of water between the cooling pipe 64 and the water tank, thereby cooling the surface of the cooling plate 66, accelerating the heat exchange between the cooling plate 66 and the placement plate 2, and assisting the pipe. The bottom of the pipeline dissipates heat, and the air flow around the pipeline is accelerated by the fan 63, so that the heat on the pipeline surface evaporates quickly. After cooling, the hydraulic push rod 5 drives the cooling mechanism 6 to move to the side away from the switching disk 44, and the hydraulic cylinder 11 drives the positioning bar 17 to move up and separate from the pipeline. The motor 22 drives the screw 23 to rotate, and the push plate 21 moves along the screw 23 to push the pipeline to move. The pipeline moves above the limit bar 13, which is convenient for quickly removing the pipeline from above the placement plate 2. After removal, the switching disk 44 continues to rotate, and the next pipeline can continue to be cooled.
