Description

Technical Field

[0001] The utility model relates to the technical field of expansion equipment, and specifically to an end expansion device for ultra-thin oxygen-free copper tubes used in air conditioners. Background Technique

[0002] The ultra-thin oxygen-free copper tube used in air conditioners is an important part of the air conditioner refrigeration system. The oxygen-free copper tube has good electrical conductivity, thermal conductivity and corrosion resistance. Its ultra-thin feature can reduce the space occupied by the internal pipeline of the air conditioner to a certain extent, which is helpful for the miniaturization and light weight of the air conditioner. Before the ultra-thin oxygen-free copper tube is sleeved, it is necessary to use an expansion device to flare the end of the copper tube, so as to facilitate the subsequent plug-in assembly.

The bottom of the hydraulic rod is fixedly connected with a support plate. The bottom of the support plate is fixedly connected with a first arc-shaped pressing block. In the above prior art, a single group of hydraulic rods drives the arc-shaped pressing block to move, so as to use the arc-shaped pressing block to extrude and limit the oxygen-free copper tube, and then use the expansion device to expand the port of the copper tube.

[0004] In the above prior art, although the copper tube can be quickly clamped and restricted by the hydraulic rod driving the arc-shaped pressing plate, the single clamping method can limit the copper tube, but the plasticity of the copper tube is strong. When the extrusion force is strong, the copper tube is easily deformed by extrusion. If the extrusion force is insufficient, the copper tube is easily pushed by the expansion device during the expansion process, resulting in an affected flaring effect. Content of the Utility Model

Detailed Embodiments

[0019] 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.

[0020] Such as Figures 1-4As shown in the figure, the utility model provides a technical solution: an ultra-thin oxygen-free copper tube end expansion device for air conditioners, including a base 1. On the upper side of one end of the base 1, a support plate 11 is fixedly connected. On the outer side of the upper end of the support plate 11, a first motor 12 is fixedly connected. The output shaft of the first motor 12 penetrates through the support plate 11 and is fixedly connected with a flaring rod 13. At one end of the base 1 away from the support plate 11, an adjusting component is fixedly connected. One end of the adjusting component is fixedly connected with a positioning component. Inside the terminal of the adjusting component, a pushing component is fixedly connected. The upper end of the pushing component is rotatably connected with a transmission component. The upper end of the transmission component is rotatably connected with a clamping component. When expanding the copper tube, first place the copper tube in the clamping component, and then start the pushing component. After the pushing component is started, it drives the clamping component to operate through the transmission component to clamp and fix the copper tube. Subsequently, start the positioning component to limit one end of the copper tube. Then start the adjusting component to drive the copper tube and the like to move closer to the flaring rod 13. When the port of the copper tube is sleeved outside the flaring rod 13, at this time, start the first motor 12 to drive the flaring rod 13 to rotate under the support of the support plate 11. At the same time, use the adjusting component to drive the copper tube to continue to move, so that the flaring rod 13 expands the port of the copper tube. When the expansion device expands the copper tube, it can make the restriction of the expansion device on the copper tube more stable, and at the same time reduce the extrusion damage caused by the clamping component and the like to the copper tube.

[0021] As Figure 1 and Figure 2 shown, the adjusting component includes a second motor 2 fixedly connected to the outer side of one end of the base 1 away from the support plate 11. The output shaft of the second motor 2 is fixedly connected with a threaded rod 21. The end of the threaded rod 21 away from the second motor 2 is rotatably connected to the base 1. On the outer side of one end of the threaded rod 21 close to the second motor 2, a threaded cylinder 22 is engaged. The upper end of the threaded cylinder 22 is fixedly connected with a housing 23. Start the second motor 2. After the second motor 2 is started, the output shaft drives the threaded rod 21 to rotate. After the threaded rod 21 rotates, through the engagement with the threaded cylinder 22, the threaded cylinder 22 drives the two housings 23 to move, so as to drive the pushing component, the transmission component, the clamping component and the copper tube and the like to move by using the movement of the two housings 23, which is convenient for the copper tube to gradually move closer to the flaring rod 13 for stable movement.

[0022] As Figure 1 and Figure 2As shown in the figure, the positioning component includes a first electric telescopic rod 3 fixedly connected to the outside of a set of outer casings 23. One end of the first electric telescopic rod 3 away from the outer casing 23 is fixedly connected to a top plate 31. A first rubber pad 32 is fixedly connected to the upper end of the side of the top plate 31 close to the outer casing 23. When the first electric telescopic rod 3 is started, the first electric telescopic rod 3 drives the top plate 31 and the first rubber pad 32 to approach the copper pipe. After the first rubber pad 32 is attached to the copper pipe, at this time, the top plate 31 and the first rubber pad 32 are used to perform secondary restriction on the copper pipe, which is convenient for restricting one end of the copper pipe and preventing the copper pipe from shifting due to unstable restriction during the flaring process.

[0023] As Figure 3 and 4 shown in the figure, the pushing component includes a second electric telescopic rod 4 fixedly connected to the inner side of the lower end of the outer casing 23. The upper end of the second electric telescopic rod 4 is fixedly connected to a push plate 41. A first push rod 42 is rotatably connected to the upper end of the push plate 41. When the second electric telescopic rod 4 is started, after the second electric telescopic rod 4 is started, the output shaft pushes the push plate 41 to move, so that the push plate 41 pushes the first push rod 42 to move, which is convenient for providing power output and thus enabling the transmission component to operate.

[0024] As Figure 3 and Figure 4 shown in the figure, the transmission component includes a sleeve 5 rotatably connected to the outside of the upper end of the first push rod 42. A limiting rod 51 is inserted into the inner side of the sleeve 5. Both ends of the limiting rod 51 are fixedly connected to the outer casing 23. A second push rod 52 is rotatably connected to the upper end of the sleeve 5. After the first push rod 42 moves, it pushes the sleeve 5 to move sleeved on the outside of the limiting rod 51, so that the sleeve 5 synchronously pushes the second push rod 52 to move. After the second push rod 52 moves, it drives the clamping component to operate, which is convenient for transmitting and differentiating the driving force of the second electric telescopic rod 4, the push plate 41 and the first push rod 42, thereby driving the two sets of clamping plates 6 and the second rubber pads 61 to rotate, and making the two sets of clamping plates 6 and the second rubber pads 61 rotate and close to clamp and restrict the oxygen-free copper pipe.

[0025] As Figure 3 and Figure 4 shown in the figure, the clamping component includes a clamping plate 6 rotatably connected to the outside of the upper end of the second push rod 52. The lower end of the clamping plate 6 is rotatably connected to the outer casing 23. A second rubber pad 61 is fixedly connected to the inner side of the clamping plate 6. After the second push rod 52 moves, it pushes the clamping plate 6 and the second rubber pad 61, and the clamping plate 6 and the second rubber pad 61 are closed to clamp and restrict the oxygen-free copper pipe, which is convenient for clamping and restricting the oxygen-free copper pipe by the closing of the two sets of clamping plates 6 and the second rubber pads 61. Furthermore, at the same time, the second rubber pad 61 is used to buffer the clamping of the clamping plate 6, thereby protecting the oxygen-free copper pipe.

[0026] Working principle: When expanding the end of the oxygen-free copper tube, first place the oxygen-free copper tube in the two groups of second rubber pads 61, and then start the second electric telescopic rod 4. After the second electric telescopic rod 4 starts, the output shaft pushes the push plate 41 to move, so that the push plate 41 pushes the first push rod 42 to move. After the first push rod 42 moves, it pushes the sleeve 5 to move outside the limit rod 51, so that the sleeve 5 synchronously pushes the second push rod 52 to move. After the second push rod 52 moves, it pushes the clamping plate 6 and the second rubber pad 61, so that the clamping plate 6 and the second rubber pad 61 close to clamp and limit the oxygen-free copper tube. Subsequently, start the first electric telescopic rod 3, so that the first electric telescopic rod 3 drives the top plate 31 and the first rubber pad 32 to approach the copper tube. After the first rubber pad 32 fits with the copper tube, at this time, use the top plate 31 and the first rubber pad 32 to perform secondary restriction on the copper tube. Subsequently, start the second motor 2. After the second motor 2 starts, the output shaft drives the threaded rod 21 to rotate. After the threaded rod 21 rotates, through the meshing with the threaded barrel 22, the threaded barrel 22 drives the two groups of outer shells 23 to move. After the outer shell 23 drives the copper tube to move, start the first motor 12, so that the output shaft of the first motor 12 drives the flaring rod 13 to rotate under the support of the support plate 11. When the copper tube is sleeved outside the flaring rod 13, the port of the copper tube can be expanded by the rotation of the flaring rod 13. After the expansion is completed, first turn off the first motor 12, and then let the output shaft of the second motor 2 rotate in the reverse direction. Subsequently, drive the outer shell 23 and the like to return by the threaded barrel 22. When the copper tube moves away from the flaring rod 13, at this time, turn off the second motor 2 and start the second electric telescopic rod 4, so that the second electric telescopic rod 4 contracts to drive the push plate 41 and the first push rod 42 and the like to return, and further let the first push rod 42 pull the sleeve 5, so that the sleeve 5 pulls the second push rod 52 to drive the clamping plate 6 and the second rubber pad 61 to rotate and open under the assistance of the limit rod 51. When the clamping plate 6 and the second rubber pad 61 are opened, the flared copper tube can be taken out.

[0027] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
