Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing equipment, in particular to an automatic ring-sleeving machine. Background Art

[0002] The condenser, or outdoor heat exchanger, is the most important device for air conditioning refrigeration. It is installed between the compressor exhaust port and the throttling device. When the high-temperature and high-pressure gas discharged from the air conditioning compressor enters the condenser, it is cooled by the copper tube and aluminum foil, so that the air conditioner blows out lower temperature air, thereby achieving the cooling effect. Existing condensers are often connected by multiple copper tubes. When the copper tubes are too long, they are not easy to bend. Therefore, U-shaped tubes are often used to connect multiple copper tubes. Therefore, the U-shaped tube needs to be welded to the top of the two copper tubes.

[0003] Before welding, the U-shaped tube needs to be put on the straight section of the U-shaped tube. The existing automatic ring-putting machine includes an upright guide trough, a material distributor (specifically a latch) vertically penetrating the upper part of the guide trough, and a core rod vertically at the bottom of the guide trough. The welding rings are arranged in the guide trough and blocked by the material distributor. When the U-shaped tube needs to be put on the ring, as the distributor reciprocates, the welding rings in the guide trough fall down to the specified position one by one, and then are aligned by the core rod vertically at the bottom of the guide trough and pushed onto the U-shaped tube. However, this automatic ring-putting machine Due to the rebound of the welding ring when it falls, the welding ring cannot fall to the specified position, which causes the core rod to sometimes fail to align with the welding ring and then push the welding ring into the U-shaped tube. In addition, this automatic ring-putting machine is only suitable for round welding rings with heavier texture. If it is replaced with a special-shaped welding ring with lighter texture, irregular shape and inconsistent inner diameter, the weight and volume of the welding ring will change, resulting in a slower descending speed, which cannot match the moving speed of the core rod. Finally, some special-shaped welding rings cannot be aligned with the core rod and pushed into the U-shaped tube, affecting the processing efficiency of the U-shaped tube. Utility Model Content

[0004] In order to solve the above problems, the utility model provides an automatic ring-making machine, including a base, one end of which is provided with an upright feeding mechanism, a pressure rod mechanism and a ring-making mechanism are also provided thereon, and the pressure rod mechanism is located at one side of the ring-making mechanism.

[0005] Furthermore, the material unloading mechanism includes a material unloading plate, a vertical material guide groove is formed on the material unloading plate, a connecting plate is embedded in the lower part of the material unloading plate, a stopper installation groove perpendicular to the material guide groove is formed on the connecting plate, and a stopper is connected to the stopper installation groove through an elastic member.

[0006] Further, the ferrule mechanism includes a first slide rail assembly, a slide plate, a second slide rail assembly, a lifting and moving plate, a first driving device, a second driving device, and a third driving device. The slide plate is slidably connected to the base through the first slide rail assembly. Vertical first and second standing plates are fixedly connected to both ends of the slide plate. The first and second standing plates are fixedly connected above through a connecting column. The first standing plate is in a U-shaped form. Both sides of the first standing plate are slidably connected to the lifting and moving plate through the second slide rail assembly. The top of the first standing plate is fixedly connected with the second driving device; the second driving device is fixedly connected to the lifting and moving plate below. A ferrule push head sleeve mounting seat is fixedly connected to one side of the lifting and moving plate close to the blanking plate. A ferrule push head sleeve is fixed on the ferrule push head sleeve mounting seat, and a mandrel is fixedly connected inside the ferrule push head sleeve; a first driving device is also fixed on the slide plate. The first driving device is located between the first and second standing plates, and one end of the first driving device is fixedly connected to the lower part of the second standing plate. The driving end of the first driving device is far from the second standing plate and is fixedly connected with a mandrel pushing plate. The first driving device drives the mandrel pushing plate to move forward through the first standing plate and abut against the ferrule push head sleeve; a third driving device mounting plate is also fixed at one end of the base far from the blanking mechanism. A third driving device is fixedly connected to the third driving device mounting plate, and the driving end of the third driving device is fixedly connected to the second standing plate.

[0007] Further, a second cylinder mounting plate is fixedly connected to the top of the first standing plate, and a second driving device is mounted on the second cylinder mounting plate. The second driving device is clamped to the lifting and moving plate through a T-shaped nut below.

[0008] Further, the pressing rod mechanism includes a hinge seat fixed on the base. A first pressing rod is arranged between the hinge seat and the blanking plate. The first pressing rod is hinged to the hinge seat. A second pressing rod is fixedly connected to the end of the first pressing rod far from the hinge seat. The second pressing rod is perpendicular to the first pressing rod. A pressing block is fixedly connected to the first pressing rod. A chute is formed on the pressing block. The chute is inclined and is higher at the end close to the blanking plate than at the end far from the blanking plate. A bearing is placed in the chute, and the bearing is fixedly connected to the slide plate through a connecting block.

[0009] Further, the first slide rail assembly includes a first slide rail and a first slider. The first slide rail is fixed on the base, and the first slide rail is slidably connected to the slide plate through the first slider.

[0010] Further, the second slide rail assembly includes a second slide rail and a second slider. The second slide rail is fixed on the first standing plate, and the second slide rail is slidably connected to the lifting and moving plate through the second slider.

[0011] Further, a guide rod is arranged between the blanking plate and the first standing plate.

[0012] Further, the first driving device, the second driving device, and the third driving device are all cylinders.

[0013] The beneficial effect is that when the automatic ring-throwing machine is working, the welding ring comes down from the feeding mechanism, and then the pressure rod mechanism acts on the ring-throwing mechanism, so that the ring-throwing mechanism aligns the welding ring and pushes the welding ring onto the U-shaped tube. Specifically, the welding rings are arranged one by one in the guide groove and are blocked by the block, and then the first driving device drives the lifting and moving plate to move the core rod upward until it is aligned with the welding ring, and then the second driving device drives the core rod to move forward until the core rod is inserted into the welding ring, and then the first driving device drives the lifting and moving plate to pull the core rod downward until it is aligned with the U-shaped tube (in this process, the block will squeeze the elastic member so that the welding ring can move downward smoothly. At the same time, since the elastic member will restore its deformation in time, the block will immediately block other welding rings to ensure that the welding rings can be taken away one by one by the core rod), and finally the third driving device drives the entire slide plate to move towards the direction close to the feeding plate until the core rod pushes the welding ring onto the U-shaped tube. At this time, the bearing will also move along the slide groove to the end close to the feeding plate, so that the first pressure rod is close to the feeding plate. The U-shaped tube is precisely pushed onto the welded ring by the mandrel rod when the welded ring falls onto the welded ring. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Please refer to Figure 3 and Figure 4 , Figure 3 for the partial structure schematic diagram of this automatic ferrule machine Figure 1 , Figure 4 for the partial structure schematic diagram of this automatic ferrule machine Figure 2A ring pusher cover mounting seat 441 is fixedly connected to the lifting and moving plate 44 near the unloading plate 21, a ring pusher cover 442 is fixed on the ring pusher cover mounting seat 441, and a core rod 443 is fixedly connected inside the ring pusher cover 442; a first driving device 45 is also fixed on the slide plate 42, the first driving device 45 is located between the first vertical plate 421 and the second vertical plate 422, and one end of the first driving device 45 is fixed to the bottom of the second vertical plate 422, the driving end of the first driving device 45 is away from the second vertical plate 422 and is fixedly connected to a core pusher plate 451, the first driving device 45 drives the core pusher plate 451 to pass through the first vertical plate 421 forward and abut against the ring pusher cover 442; a third driving device mounting plate 425 is also fixed to the end of the base 1 away from the unloading mechanism 2, a third driving device 47 is fixedly connected to the third driving device mounting plate 425, and the driving end of the third driving device 47 is fixedly connected to the second vertical plate 422. In order to ensure that the third driving device 47 can move along a fixed track toward the blanking plate 21 each time, the present application further provides a guide rod between the blanking plate 21 and the first vertical plate 421 .

[0044] See also Figure 1 The pressure rod mechanism 3 includes a hinge seat 31, which is fixed on the base 1. A first pressure rod 32 is provided between the hinge seat 31 and the blanking plate 21. The first pressure rod 32 is hinged to the hinge seat 31. The first pressure rod 32 is fixedly connected to the second pressure rod 33 at one end away from the hinge seat 31. The second pressure rod 33 is vertically arranged with the first pressure rod 32. A pressure block 34 is fixedly connected to the first pressure rod 32.

[0045] When in use, the welding rings are first arranged one by one in the guide groove 211 and blocked by the stopper 222. Then, the first driving device 45 drives the lifting and moving plate 44 to move the core rod 443 upward until it is aligned with the welding ring. Then, the second driving device 46 drives the core rod 443 to move forward until the core rod 443 is inserted into the welding ring. Then, the first driving device 45 drives the lifting and moving plate 44 to pull the core rod 443 downward until it is aligned with the U-shaped tube (in this process, the stopper 222 will squeeze the elastic member 223 so that the welding ring can be smoothly moved). The first pressing rod 32 is pressed against the first pressing rod 32, and the second pressing rod 32 is pressed against the first pressing rod 32. Under the action of structure 3, it can remain stable for a long time without shaking, so that the welding ring can be accurately pushed onto the U-shaped tube, thereby improving work efficiency. Compared with the existing automatic ring-putting machine, the welding ring in the guide groove is first blocked by the material distributor. When the U-shaped tube needs to be put on the ring, as the material distributor reciprocates, the welding rings in the guide groove fall down one by one. In the process of the welding ring falling, they are captured and aligned by the core rod and pushed onto the U-shaped tube. In the automatic ring-putting machine, the welding ring is aligned and inserted by the core rod 443 in the guide groove 211. This welding ring is put on in a stationary state. The accuracy of being aligned and inserted by the core rod 443 is higher, which can ensure that each welding ring can be aligned and inserted by the core rod 443, and solves the technical problem that some welding rings cannot be aligned and pushed into the U-shaped tube by the core rod 443 due to the mismatch between the falling speed of the welding ring and the reciprocating speed of the core rod 443; the device has a simple structure, safe use, and strong practicality, and can realize the accurate pushing of welding rings of various qualities and shapes onto the U-shaped tube without worrying about the mismatch between the falling speed of the welding ring and the reciprocating speed of the core rod.
