Description

Technical Field

[0001] The present invention relates to the technical field of heat exchanger processing and production equipment, and particularly to a fully automatic assembly platform for heat exchangers. Background Technique

[0002] A heat exchanger is an energy-saving device that realizes heat transfer between materials among two or more fluids at different temperatures, which enables heat to be transferred from a fluid with a higher temperature to a fluid with a lower temperature, so that the fluid temperature reaches the specified index of the process to meet the requirements of process conditions. At the same time, it is also one of the main devices for improving energy utilization efficiency.

[0003] When a heat exchanger is produced, during the production and processing of the heat exchanger, it includes multiple processes. For example, various components are processed separately, and various required parts are assembled.

[0004] Among the various processes of heat exchanger processing and production, the processing, production, and screening of parts are the most basic and of course very important. And the most important is the assembly work of the heat exchanger, that is, the installation between the pipes and the frame of various heat exchangers. The existing technical solutions mostly adopt the manual installation method, and there is no good automatic processing equipment for heat exchanger assembly at present. The technical solution of manual assembly not only has relatively low efficiency, but also has various problems during the assembly process. For example, when manually assembling a heat exchanger, the most intuitive problem is the production efficiency of processing and assembly. Because the manual assembly method is too easily affected by external factors, with large interference, and the workload of the assembly personnel is also a major factor affecting the assembly efficiency. Secondly, the error rate of manual assembly is also a big problem. In the manual assembly method, the docking installation positions, angles, and forces during docking installation of various parts are all inconsistent. Therefore, the quality of each product is different, and it is easy to make mistakes during docking installation, and then rework is required. Finally, there is the safety issue. Here, the safety issue not only refers to the safety of the heat exchanger product, but also the safety of the operator during the assembly operation.

[0005] Therefore, we propose a fully automatic assembly platform for heat exchangers to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] The present invention provides a technical solution for a fully automatic assembly platform of a heat exchanger: Embodiment

[0022] AsFigure 1 As shown, the assembly platform of this technical solution mainly consists of a hydraulic system 1, a mounting motor system 2, and a moving platform 3, and the three are docked and installed in sequence from left to right as shown in the figure. Figure 1 shown in the figure.

[0023] As Figure 1 and Figure 2 shown, the hydraulic system 1 mainly consists of an outer chassis 11. Inside the inner cavity of the outer chassis 11, hydraulic mechanisms 12 are installed at equal distances. A power output pipe 13 is docked and installed at the output port of the hydraulic mechanism 12.

[0024] As Figure 1 and Figure 3 shown, the mounting motor system 2 mainly consists of a grounding frame 21, a left back plate 22, a right side plate 23, a hydraulic motor 24, a drive shaft 25, and an assembly sleeve 26. The left back plate 22 is installed on the left side of the top of the grounding frame 21 through fasteners. The right side plate 23 is installed on the right side of the top of the grounding frame 21 through bolt fasteners. A through hole for installing the hydraulic motor 24 is opened on the side surface of the left back plate 22. The hydraulic motor 24 is installed through the through hole. The left end of the drive shaft 25 is docked and installed with the output shaft of the hydraulic motor 24 through a coupling. A through hole structure is also opened on the side surface of the right side plate 23, and a bearing structure is installed inside the through hole structure. The assembly sleeve 26 is inserted into the inner ring of the bearing structure.

[0025] As Figure 1 and Figure 4 shown, the moving platform 3 mainly consists of a base plate 31, a lifting frame 32, a horizontal track 33, a horizontal moving plate 34, a vertical track 35, and a vertical moving plate 36. The lifting frame 32 is installed on the top of the base plate 31 through bolt fasteners. The horizontal track 33 is installed on both sides of the middle of the top of the lifting frame 32 through bolt fasteners. The horizontal moving plate 34 is installed on the top of the horizontal track 33. The vertical track 35 is installed on the top of the horizontal moving plate 34 through bolt fasteners. The vertical moving plate 36 is installed on both sides of the middle of the top of the vertical track 35.

[0026] Among them, a flange structure is provided on the outer ring of the hydraulic motor 24, and the flange structure fits on both side surfaces of the left back plate 22 and is installed and fixed through bolt fasteners.

[0027] Among them, the left end face of the assembly sleeve 26 is provided with a hexagonal groove, and the right end of the drive shaft 25 is integrally fixedly connected with a hexagonal shaft, which is plugged into the hexagonal groove on the left end face of the assembly sleeve 26. The assembly sleeve 26 and the drive shaft 25 are assembled in a plug-in manner, which is to increase the convenience of operation and maintenance work, and secondly, the distance between the assembly sleeve 26 and the hydraulic motor 24 can be adjusted in real time according to the size of the heat exchanger, which increases the flexibility of the entire assembly platform.

[0028] The number of installed motor systems 2 is at least two, and the spacing and sizes between the assembly sleeves 26 on the two motor systems 2 are different, mainly to adapt to the assembly of heat exchangers of different specifications. That is, when assembling heat exchangers of different sizes, the positions of the bolts and other structures on the heat exchanger are different, so the appropriate installation motor system 2 can be selected according to the actual processing conditions.

[0029] The bottom of the horizontal moving plate 34 and the vertical moving plate 36 are both provided with limit blocks, which are respectively mounted on the outside of the horizontal track 33 and the vertical track 35. The limit blocks are connected to the hydraulically driven horizontal track 33 and the vertical track 35 by bolt fasteners, mainly to prevent the horizontal moving plate 34 and the vertical moving plate 36 from slipping off during use, causing installation failures, and on the other hand, to increase the convenience of maintenance and replacement of the horizontal moving plate 34 and the vertical moving plate 36.

[0030] The end of the base plate 31 is fixedly connected with a mounting member 37 , and the entire mobile platform 3 is docked and mounted to the ground frame 21 through the mounting member 37 and bolt fasteners.

[0031] Among them, the horizontal track 33 and the vertical track 35 are both driven by hydraulic cylinders. The hydraulic system 1 provides power for the hydraulic cylinders and hydraulic motors. Each hydraulic mechanism is independent and can independently control each hydraulic motor 24, horizontal track 33 and vertical track 35.

[0032] Among them, the number of hydraulic motors 24 is less than the number of assembly sleeves 26, that is, one hydraulic motor 24 controls the action of multiple assembly sleeves 26, and each assembly sleeve 26 is connected by a pulley and a belt. In this technical solution, the assembly sleeves are mainly divided into two groups, and the assembly sleeves in each group are connected by transmission.

[0033] In this embodiment, when using this technical solution to assemble the heat exchanger, Figure 1As shown, on the side of the hydraulic system is a heat exchanger structure. There are bolts designed on its plates. When installation is required, directly place the semi-finished heat exchanger on the assembly platform, that is, on the horizontal moving plate 34. Then, through the hydraulic system 1, control the vertical track 35 to adjust the position of the vertical moving plate 36 and the semi-finished heat exchanger, so that the heat exchanger product is placed at the center of the grounding frame 21, and the positions of each bolt structure and the sleeve structure correspond one by one. Then, through the hydraulic system, control the horizontal track 33 to act, and then gradually sleeve the bolt structure on the semi-finished heat exchanger onto the assembly sleeve 26. After that, through the hydraulic system, control the hydraulic motor 24 to act. When the hydraulic motor 24 acts, it will drive the assembly sleeve 26 to perform corresponding actions through the drive shaft 25, thereby realizing the assembly operation of the semi-finished heat exchanger.

[0034] In this technical solution, the assembly work of the entire heat exchanger is first realized through automated actions. Compared with the traditional manual assembly solution, not only is the assembly efficiency improved, but also the accuracy of the docking and assembly of each component during the heat exchanger assembly process is greatly improved. At the same time, the manual operation links and labor input are greatly reduced. It not only realizes the safety of production, but also undoubtedly greatly reduces the production cost during long-term production, which is conducive to popularization and promotion.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
