The embodiments of the present disclosure can be performed independently of each other, or can be performed together in a mutually dependent relationship.

[0031] Reference Figures 1 to 7 The utility model discloses a condenser multi-tube end combined processing all-in-one machine, including a frame 1 and a clamping mechanism arranged on the frame 1 for clamping the condenser 2. The frame 1 is mainly a square platform. A translation seat 1 3 and a translation seat 2 4 are arranged on the frame 1. The clamping mechanism is located between the translation seat 1 3 and the translation seat 2 4, so that it is convenient to process both ends of the condenser 2 at the same time. The clamping mechanism in this application adopts an automatic clamping structure, which mainly includes a clamping table 5. There are a fixed clamping plate and a movable clamping plate on the clamping table 5. The movable clamping plate is moved by a cylinder 6 arranged on the clamping table 5, so that the condenser 2 is clamped between the fixed clamping plate and the movable clamping plate.

[0032] In the present application, the translation seat 3 is moved on the frame 1 by a linear motion mechanism, and the linear motion mechanism includes a linear guide assembly 7 and a screw assembly 1 installed on the frame 1. The translation seat 3 is connected to the linear guide assembly 7 and the screw assembly 1, and the screw assembly 1 is provided with an adjustment handle 8. The above structure can adjust the position of the translation seat 3 relative to the platform through the adjustment handle 8. The translation seat 3 of the present application can move relative to the platform in order to cooperate with the inclined tube processing device to adjust the angle and distance, so the translation seat 3 is provided with an inclined tube processing device with an adjustable angle, so that the processing unit on the translation seat 3 can process the tube end of the condenser tube 2, while the processing unit on the adjustment plate can process the tube end of the branch tube.

[0033] like Figure 1 and 2 As shown, the translation seat 1 3 and the translation seat 2 4 are both provided with a lifting seat 9, and a plurality of processing units 10 are provided on the lifting seat 9. The translation seat 1 3 and the translation seat 2 4 are connected to the lifting seat 9 through corresponding lifting mechanisms, and the lifting mechanisms include two linear guide rail assemblies 2 11 respectively installed on the translation seat 1 3 and the translation seat 2 4 and two screw rod assemblies 2 respectively installed on the translation seat 1 3 and the translation seat 2 4. The linear guide rail assemblies 2 11 corresponding to the lifting seat 9 are connected to the screw rod assemblies 2, and the screw rod assemblies 2 are connected to the corresponding driving motors. The machine 12 is connected, and the lifting and lowering movement of the lifting seat 9 is realized through the above-mentioned structure, so that different processing units 10 can be moved to the position opposite to the condenser 2 for processing. The processing unit 10 can be one or more of a flat end surface unit, a flaring unit, a shrinking unit, a tube expansion unit, etc., and of course it can also include the shrinking dotting unit of the present application. The structure of the above-mentioned flat end surface unit, flaring unit, shrinking unit, and tube expansion unit is not changed, but it is installed as a whole on the lifting seat 9 or the adjustment plate, so its specific structure and function are not described in detail.

[0034] In the above structure, the drive motor 12, the linear guide assembly and the lead screw assembly are all existing products, so their specific connection parts are described in detail.

[0035] like Figures 3 to 5 As shown, the inclined pipe processing device includes a mounting plate 13 and an adjusting plate 14 hinged to the mounting plate 13, the mounting plate 13 is provided with an angle adjustment pushing mechanism capable of pushing the adjusting plate 14 to rotate around a hinge point, the adjusting plate 14 is provided with a processing unit 10, the angle of the adjusting plate 14 can be adjusted by the above structure, the angle of the adjusting plate 14 can be converted from a 20 degree inclined surface to a 40 degree angle in the present application, and the movement of the translation seat 13 is coordinated so that the processing unit 10 is directly opposite to the branch pipe to process the branch pipe, in the above structure, the processing unit 10 is a tube expansion unit and a flat end surface unit, so as to perform the process of expanding and flattening the end surface of the branch pipe, and of course, it can also be other processing units 10.

[0036] The pushing mechanism includes an adjusting member 15 arranged on the mounting plate 13, a supporting plate 16, an adjusting screw hole arranged on the supporting plate 16, and an adjusting screw 17 matched with the adjusting screw hole. The adjusting screw 17 is fixedly connected to the adjusting member 15 to drive the adjusting member 15 to move forward and backward so as to squeeze the adjusting plate 14. In the present application, in order to guide and reduce friction, the adjusting member 15 is connected to the mounting plate 13 through a guide rail assembly, and a bearing 18 is provided on the adjusting member 15. The bearing 18 contacts and squeezes the adjusting plate 14. The bearing 18 is fixed to the adjusting member 15 through an axis, and the adjusting member 15 is a square plate. Of course, the above is only the preferred structure of the present application. We can also directly make the adjusting member 15 contact with the adjusting plate 14 to rotate the adjusting plate 14, and the shape of the adjusting member 15 can also be a triangle or a semicircle, etc. In the above, there is a handle at the end of the adjusting screw 17, and the adjusting member 15 is driven to move by manually rotating the handle, thereby adjusting the angle of the adjusting plate 14. The preferred adjusting screw 17 is a thread with a self-locking function.

[0037] As shown in the figure, the side plates 19 are arranged opposite to each other on the mounting plate 13, the adjusting plate 14 is hinged to the side plates 19, and an arc-shaped guide groove 20 is arranged on the side plates 19. Guide rods slidingly matched with the guide grooves 20 are arranged opposite to each other on both sides of the adjusting plate 14, so that the adjusting plate 14 will not deviate when rotating, and it will be more accurate. The side plates 19 are fixed to the lifting seat 9, thereby forming a frame-type supporting structure together with the mounting plate 13.

[0038] As a preferred structure, the processing unit 10 of the present application also includes a shrinking and dotting unit. The previous shrinking unit only performed shrinking processing on the tube end, but in order to improve efficiency and precision, we integrated the shrinking process and the dotting process together. Therefore, the shrinking and dotting unit of the present application has redesigned the tool head, which can not only realize the shrinking function but also dot the tube end at the same time. In this way, there is no need to use an additional dotting machine to dot the condenser tube 2 after shrinking as before.

[0039] like Figure 6 and 7 As shown, the necking dotting unit includes a forming core 21, a necking die base 22 and a necking die body 23. The necking die base 22 is provided with a mounting hole. The necking die body 23 is located in the mounting hole and is fixed to the necking die base 22. The above fixation is preferably a threaded connection. There are threads in the mounting hole and threads on the outer wall of the die body. The above structure is not only convenient for processing, but also convenient for assembly and disassembly.

[0040] The shrinking die body 23 is provided with a forming hole 24, and the aperture size of the forming hole 24 is the size of the tube diameter to be shrunk. The forming core 21 is located in the forming hole 24 and is fixed to the shrinking die base 22. The forming core 21 is supported internally to prevent the copper tube from sinking when shrinking the tube, and can ensure that the inner diameter of the copper tube is uniform. The bottom of the mounting hole is provided with a core rod connecting screw hole, and the end of the forming core 21 is provided with a connecting stud 5 connected to the core rod connecting screw hole. The above structure is not only convenient for processing, but also convenient for assembly and disassembly.

[0041] A forming guide structure is provided between the orifice of the forming hole 24 and the end of the forming core 21. Specifically, the forming guide structure comprises a conical body 26 provided at the end of the forming core 21 and a conical hole 27 provided at the orifice of the forming hole 24. The gap between the conical hole 27 and the conical body is slightly larger than the thickness of the copper tube. The large mouth of the conical hole 27 faces outward, and the end with a larger diameter of the conical body faces outward. The copper tube is inserted from the large mouth of the conical hole 27 and is slowly shrunk to a predetermined aperture through the extrusion guidance of the conical hole 27. Of course, the conical body also cooperates with the conical hole 27 to slowly support the tube wall of the copper tube and guide the inner hole of the copper tube to reach a predetermined size.

[0042] As shown in the figure, the shrinking mold body 23 is provided with a sliding hole that passes through the forming hole 24, and a punching pin 28 is provided in the sliding hole. The shrinking mold body 23 is provided with a pressing sleeve 29 that drives the punching pin 28 to move and punch a hole on the condenser 2, and a reset mechanism that resets the punching pin 28. The condenser 2 is preferably a copper tube. Its specific structure is that the inner hole of the pressing sleeve 29 is a tapered hole and the end of the shrinking die body 23 is a cone that slides with the tapered hole, and the dotting pin 28 is gradually squeezed and punched by changing the diameter of the tapered hole. The reset mechanism includes a reset spring 30, a limiting boss 31 provided in the sliding hole, and a limiting convex cap 32 provided at the tail end of the dotting pin 28. The reset spring 30 is arranged on the dotting pin 28 and one end is against the limiting boss 31, and the other end is against the limiting convex cap 32, and the sliding hole is arranged on the cone. The above structure can ensure that the reset spring 30 can achieve the reset function. The top surface of the limiting convex cap 32 is an inclined arc surface with the same inclination angle as the hole wall of the inner hole, so that the top surface can be completely in contact with the hole wall of the inner hole, thereby reducing the point contact pressure, reducing the wear of the components, and the force is evenly distributed.

[0043] The working principle of the shrinking dotting unit is that the cutter head as a whole is driven to move by a driving system, which can be a system composed of a conventional motor, a reducer, a screw assembly and a guide rail assembly, so that the cutter head as a whole moves toward the end of the copper tube. After moving into position, the end of the condenser tube 2 will be inserted into the forming hole 24, and then the driving system drives the cutter head to continue to move until all the copper tubes of a predetermined length are shrunk. When the cutter head moves to a point close to the mold, it stops, and the dotting push cylinder (not shown in the figure) will move to drive a dotting push plate to contact and squeeze the pressing sleeve 29 to push the pressing sleeve 29 to move. Therefore, the pressing sleeve 29 will move relative to the shrinking die body 23, so that the dotting pin 28 will be quickly squeezed to move into the forming hole 24 during the movement, so that the dotting pin 28 will dot the copper tube. The dotting push cylinder can be fixed on the shrinking die base 22 through the bracket and move with the cutter head. When the cutter head is reset, the dotting pin 28 will also be reset under the action of the reset spring 30, and the sub-sleeve will be squeezed to reset it. Of course, in order to prevent the pressing sleeve 29 from completely disengaging, a limiting convex surface is provided in the inner hole of the pressing sleeve 29, and the limiting convex surface can be stuck with the limiting convex cap 32 of the dotting pin 28, so as to prevent the pressing sleeve 29 from completely disengaging. Moreover, the dotting of the above device can be completed without the need for additional power, which greatly saves costs and time, thereby improving work efficiency.

[0044] In summary, since this mechanism can shrink or expand the material tube at the same time or perform dotting while shrinking the tube, after adopting this mechanism, its performance is stable, practical, efficient, precise and durable.
