Description

Technical Field

[0001] The invention belongs to the technical field of refrigeration equipment manufacturing, and particularly relates to a condenser heat exchange coil welding turntable. Background Art

[0002] The condenser, a component of a refrigeration system and a type of heat exchanger, converts gas or vapor into liquid, rapidly transferring heat from the tubes to the surrounding air. The condenser's operating process is heat-releasing, so the condenser temperature is typically relatively high. Gas passes through a long tube (usually coiled into a solenoid), dissipating heat into the surrounding air. Metals like copper, due to their high thermal conductivity, are often used to transport vapor. To improve condenser efficiency, heat sinks with excellent thermal conductivity are often attached to the tubes to increase the heat dissipation area and accelerate heat dissipation. A fan also increases air convection to remove heat. The typical refrigeration principle of a refrigerator is that the compressor compresses the working fluid from a low-temperature, low-pressure gas into a high-temperature, high-pressure gas. This gas then passes through the condenser and condenses into a medium-temperature, high-pressure liquid. After being throttled by a throttle valve, it becomes a low-temperature, low-pressure liquid. This low-temperature, low-pressure liquid is then fed into the evaporator, where it absorbs heat and evaporates into low-temperature, low-pressure vapor, which is then fed back into the compressor, completing the refrigeration cycle.

[0003] In the past, welding was often fixed-point welding. During the welding process, the heat exchange coil was usually fixed and the workers moved to perform welding. This working method not only increased the labor intensity of the workers but also reduced efficiency. In the existing technology, people placed the workpiece on a turntable for welding, which saved labor intensity. However, there was still a risk that the turntable would be accidentally touched during the welding process, causing welding errors and failing to achieve the desired effect.

DETAILED DESCRIPTION

[0024] The technical solution of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0025] Example: A condenser heat exchange coil welding turntable, such as Figure 1-Figure 4 As shown, the condenser heat exchange coil welding turntable includes a base 3, a connecting shaft 9 rotatably mounted above the base 3, and a turntable 1 fixedly mounted on the end of the connecting shaft 9;

[0026] The base 3 is further fixedly provided with a butt plate 2 and a vertical plate 4. The butt plate 2 and the vertical plate 4 are symmetrically arranged on both sides of the base 3, and a driving assembly is provided between the butt plate 2 and the vertical plate 4. The driving assembly drives the turntable 1 to rotate through a transmission mechanism provided on the connecting shaft 9. The transmission mechanism is used to drive the turntable 1 to rotate in one direction, and drives the condenser heat exchange coil fixed on the turntable 1 to rotate in one direction, thereby adjusting the welding position of the condenser heat exchange coil;

[0027] A locking assembly is provided between the driving assembly and the turntable 1 , and the locking assembly is used to fix or unlock the welding position of the condenser heat exchange coil.

[0028] In an embodiment of the present invention, when it is necessary to weld the condenser heat exchange coil, the condenser heat exchange coil is fixed on the turntable 1, and the locking component is driven by human power to unlock the turntable 1. The driving component then drives the connecting shaft 9 to rotate on the base 3 through the transmission mechanism. At the same time, the turntable 1 drives the condenser heat exchange coil to rotate, and in this process, the welding position of the condenser heat exchange coil is adjusted. Finally, the locking component is driven by the reset of the driving component to lock the position of the turntable 1.

[0029] As an embodiment of the present invention, the drive assembly includes a spring 13 fixedly mounted on the side end of the abutment plate 2, a spring sleeve 10 sleeved on the outer circumference of the spring 13, a push rod 6 fixedly connected to the spring 13, and a handle 5 fixedly arranged at the end of the push rod 6;

[0030] The push rod 6 is movably disposed in a through hole provided on the vertical plate 4 , and the push rod 6 is in contact with the inner wall of the spring sleeve 10 .

[0031] In the embodiment of the present invention, when the welding position of the condenser heat exchange coil needs to be adjusted, the handle 5 is pushed manually to drive the push rod 6 to move in the through hole provided on the vertical plate 4, and the push rod 6 drives the locking assembly to move to unlock the turntable. The push rod 6 moves in the spring sleeve 10 and compresses the spring 13, so that the spring 13 accumulates elastic potential energy. In this process, the push rod 6 drives the transmission mechanism to rotate the turntable 1. After the welding position of the condenser heat exchange coil is adjusted, the handle 5 is released, and the elastic potential energy accumulated in the spring 13 is released, so that the push rod 6 pops out, so that the locking assembly moves and locks the position of the turntable at this time.

[0032] This allows workers to freely adjust the position of the condenser heat exchange coil when welding it, and ensures that the coil is fixed after adjusting the position, avoiding problems such as accidentally touching the turntable.

[0033] As an embodiment of the present invention, the locking assembly includes a slot structure provided below the turntable 1 and a key structure installed above the push rod 6;

[0034] The key structure includes a connecting rod 11 fixedly mounted on the upper end of the push rod 6 and a fixing pin 12 fixedly arranged on the side end of the connecting rod 11 .

[0035] In an embodiment of the present invention, when the push rod 6 compresses the spring 13, the push rod 6 drives the connecting rod 11 to move, causing the fixing pin 12 to disengage from the slot structure, thereby unlocking the turntable 1. When the spring 13 releases its elastic potential energy, the push rod 6 drives the fixing pin 12 to insert into the slot structure, thereby locking the turntable 1.

[0036] As an embodiment of the present invention, the slot structure includes a circular slot 19 provided below the turntable 1 and a plurality of circular holes 20 equidistantly provided on the side ends of the circular slot 19 , and the circular holes 20 are adapted to fit the fixing pins 12 .

[0037] In the embodiment of the present invention, when the fixing pin 12 moves in the circular groove 19 and disengages from the circular hole 20 , the turntable 1 is unlocked. Conversely, when the fixing pin 12 is inserted into the circular hole 20 , the turntable 1 is locked.

[0038] As an embodiment of the present invention, the transmission mechanism includes a one-way motion component mounted on the connecting shaft 9 and an engaging component connecting the push rod 6 and the connecting shaft 9;

[0039] The one-way motion assembly includes a wedge 17 fixedly mounted on the connecting shaft 9, a ratchet 16 rotatably arranged on the lower end of the wedge 17, and an elastic structure arranged on the wedge 17;

[0040] The elastic structure includes a torsion spring 15 fixedly mounted below the wedge block 17 , a pin 18 rotatably disposed below the wedge block 17 , and a pawl 14 fixedly mounted on the pin 18 , wherein the side ends of the pawl 14 abut against the torsion spring 15 and the ratchet 16 , respectively.

[0041] In an embodiment of the present invention, when the push rod 6 is pushed, the push rod 6 drives the ratchet 16 to rotate counterclockwise through the engaging assembly, and the pawl 14 abuts against the ratchet 16 through the torsion spring 15, so that the ratchet 16 drives the wedge 17 to rotate, causing the turntable 1 to rotate and adjust the position. Conversely, when the push rod 6 is popped out by the spring 13, the engaging assembly drives the ratchet 16 to rotate clockwise. During this process, the back of the ratchet 16 teeth drives the pawl 14 to squeeze the spring, and the pawl 14 drives the pin 18 to deflect on the wedge 17. The pawl 14 slides over the back of the ratchet 16 teeth, and the wedge 17 is fixed until the fixing pin 12 is inserted into the round hole 20, and the position of the turntable 1 is locked.

[0042] As an embodiment of the present invention, the engaging assembly includes a rack plate 7 fixedly mounted on the side end of the push rod 6 and a gear 8 fixedly arranged on the outer periphery of the ratchet 16 , and the gear 8 is adapted to the rack plate 7 .

[0043] In the embodiment of the present invention, when the push rod 6 is pushed, the push rod 6 drives the rack plate 7 to move. When the rack plate 7 is engaged with the gear 8, the rack plate 7 drives the gear 8 to rotate counterclockwise. At this time, the turntable 1 rotates. When the push rod 6 is released, the rack plate 7 drives the gear 8 to rotate clockwise.

[0044] It should also be added that the rack plate 7 is only provided with half section on the push rod 6, so that the fixing needle 12 is withdrawn from the circular hole 20 in the first half of the push rod 6 to unlock the turntable 1, and the turntable 1 is rotated by the engagement of the rack plate 7 and the gear 8 in the second half.
