Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile air conditioner auxiliary tooling, and specifically relates to a heat dissipation fin roller die maintenance device. BACKGROUND

[0002] The heat dissipation fin is a vital component inside an automobile air conditioner, and the control of its specifications and dimensions is extremely strict. Therefore, the heat dissipation fin roller of the die must be regularly maintained after being used for a period of time.

[0003] During the grinding process of the heat dissipation fin roller die, the parts that need to be disassembled include the heat dissipation fin roller, the roller shaft and the bearing seat. At present, the mode adopted is that two operators disassemble and separate the heat dissipation fin roller from the roller shaft and the bearing seat by means of a hammer and other tools. Subsequently, the bearing inside the bearing seat is replaced, and the heat dissipation fin roller is disassembled and ground. After the grinding work is completed, the two operators still need to assist in reinstalling the heat dissipation fin roller on the roller shaft by means of a hammer, and then the roller shaft is installed back to the bearing seat.

[0004] The above replacement process requires close cooperation of two operators, but due to the extremely large weight of the heat dissipation fin roller die, there is a high risk in this process, which not only poses a potential threat to the personal safety of the operators, but also may affect the integrity of the die.

[0034] Please refer to Figure 1 The embodiment provides a fin roller mold maintenance device, which comprises:

[0035] Hydraulic machine: as the core power source of the device, responsible for providing the pressure and power required for lifting operation; it is installed on the first fixed plate to ensure the stability and reliability of power transmission;

[0036] First fixed plate: as the support structure of the hydraulic machine;

[0037] Guide rod: the main function is to provide guiding function, to ensure that the floating plate can move smoothly along the guide rod during lifting; the top of the guide rod is connected with the periphery of the first fixed plate, forming a stable guiding frame.

[0038] Floating plate: it is connected with the output shaft of the hydraulic machine, and transmits the pressure generated by the hydraulic machine to the roller shaft; the floating plate is sleeved on the guide rod and can move up and down along the guide rod, thereby realizing the lifting function.

[0039] Second fixed plate: connected at the bottom of the guide rod, serving as a support. A through hole is formed in the second fixed plate, and the diameter of the through hole is smaller than the outer diameter of the fin roller, so that the fin roller is placed in the through hole during disassembly and assembly.

[0040] Hydraulic machine manual pump: in order to facilitate the operation and control of the lifting action of the hydraulic machine, a hydraulic machine manual pump is arranged on one side of the second fixed plate, which is connected with the hydraulic machine through the oil inlet pipe and the oil outlet pipe, and the output pressure and lifting speed of the hydraulic machine can be adjusted conveniently through manual operation.

[0041] As a preferred embodiment provided by the embodiment, a hydraulic oil tank is arranged on one side of the second fixed plate, and the main function of the hydraulic oil tank is to store hydraulic oil and provide continuous oil supply for the hydraulic machine manual pump, so as to ensure that the hydraulic machine can stably and continuously output power.

[0042] As the preferred embodiment provided by the present embodiment, the guide plates are sleeved on the guide rods, and the guide plates are fixed on the floating plate and form an integral whole with the floating plate. The main function of the guide plates is to further enhance the guiding function of the guide rods and ensure that the floating plate can move along the guide rods during the lifting process.

[0043] As the preferred embodiment provided by the present embodiment, the guide rod ends are connected to the first fixed plate and the second fixed plate respectively by using the jackscrews. This mounting method is not only simple and fast, but also can ensure the close connection between the guide rods and the fixed plates.

[0044] As the preferred embodiment provided by the present embodiment, the hydraulic machine is fixed above the first fixed plate through the base, and a through hole matched with the output shaft of the hydraulic machine is formed on the first fixed plate to ensure that the output shaft can smoothly pass through and be connected to the floating plate. This fixing method is not only stable and reliable, but also can ensure that the hydraulic machine will not shake or displace during the working process, thereby further improving the working efficiency and stability of the lifting device.

[0045] As the preferred embodiment provided by the present embodiment, the second fixed plate is provided with frame support legs around the lower surface to enhance the support force and stability of the entire lifting device.

[0046] During installation, the thin body part of the roller shaft is inserted into the inside of the finned roll. Then, the floating plate is gradually pressed down on the roller shaft by operating the hydraulic machine. Under the pressure of the floating plate, the thick body part of the roller shaft is smoothly pushed into the finned roll, thereby completing the installation process of the roller shaft. This installation method is not only simple and fast, but also can ensure the close cooperation between the roller shaft and the finned roll.

[0047] During disassembly, the top of the roller shaft is pressed down by operating the hydraulic machine. Under the continuous pressure of the floating plate, the thick body part of the roller shaft gradually separates from the finned roll. This disassembly method is not only labor-saving and efficient, but also can avoid damaging the roller shaft and the finned roll.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
