It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0032] Please see attached Figure 3 and Figure 4 The utility model provides a vibration isolator disassembly tool for disassembling a vibration isolator body 700, including a partition 100, a reducer 200, a hand wheel 300, a lower wrench 400, a shell 500 and an upper wrench 600; the reducer 200 is arranged on one side of the partition 100, the input end of the reducer 200 is connected to the hand wheel 300, and the output end is connected to the lower wrench 400; the shell 500 is arranged on the other side of the partition 100, the lower wrench 400 penetrates the partition 100 and extends to the inside of the shell 500, and the rotation center of the lower wrench 400 coincides with the rotation center of the vibration isolator body 700; the upper wrench 600 is detachably connected to the top of the shell 500; wherein the vibration isolator body 700 is hidden in the shell 500, and the end covers 720 at both ends of the vibration isolator body 700 are detachably connected to the lower wrench 400 and the upper wrench 600 respectively.

[0033] Please see attached Figure 1 and Figure 2In this embodiment, the vibration isolator body 700 includes a metal rubber 710, an end cap 720, and a cylindrical spring 730; one side of the end cap 720 is provided with a threaded extension, and the end of the cylindrical spring 730 can be screwed into the extension to ensure the reliability of the connection between the two; the center of the end cap 720 is provided with a first end cap positioning hole 721, and threaded holes corresponding to the first end cap positioning hole 721 are provided at both ends of the metal rubber 710, and it is ensured that the threaded holes are located on the center line of the metal rubber 710; a screw is used to penetrate the first end cap positioning hole 721 and screwed into the threaded hole to complete the fixation between the end cap 720 and the metal rubber 710. The disassembly tool of the vibration isolator in this embodiment is mainly aimed at the disassembly between the end cap 720 and the cylindrical spring 730.

[0034] In a specific embodiment, a lower wrench positioning rod 410 is provided on the lower wrench 400, and an upper wrench positioning rod 610 is provided on the upper wrench 600. The lower wrench positioning rod 410 and the upper wrench positioning rod 610 match the second end cover positioning hole 722 on the end cover 720; wherein, the second end cover positioning hole 722 on the end cover 720 is eccentrically arranged relative to the rotation center of the vibration isolator body 700.

[0035] In this embodiment, the shell 500 is cylindrical, and its inner diameter is larger than the diameter of the end cover 720, so that the vibration isolator body 700 can be smoothly hidden in the shell 500; after the vibration isolator body 700 is placed in the shell 500, the lower wrench positioning rod 410 is inserted into the first end cover positioning hole 721 on the end cover 720 on one side of the vibration isolator body 700 to achieve the connection between the end cover 720 on this side and the lower wrench 400, and then the wrench 600 is installed on the top of the shell 500, and the first end cover positioning hole 721 on the end cover 720 on the other side of the vibration isolator body 700 is inserted into the lower wrench positioning rod 410. The upper wrench positioning rod 610 is inserted into 721 to realize the connection between the side end cover 720 and the upper wrench 600, and the installation of the vibration isolator body 700 is completed; when disassembling, the hand wheel 300 is operated to input torque, and the torque is amplified by the reducer 200 and acts on the lower wrench 400. Since the upper wrench 600 and the metal rubber 710 are relatively fixed and the torque center of the lower wrench 400 coincides with the center line of the metal rubber 710, the loss of torque and the damage to the structure of the vibration isolator body 700 are avoided, which facilitates the disassembly of the vibration isolator body 700.

[0036] The principle structure of the reducer 200 in this embodiment is as shown in the attached Figure 5As shown, the reducer 200 includes a reducer housing 210, an input shaft 220, a driving bevel gear 230, a driven bevel gear 240 and an output shaft 250; the input shaft 220 and the output shaft 250 are respectively rotatably connected to the reducer housing 210; one end of the input shaft 220 is connected to the hand wheel 300, and the other end is connected to the driving bevel gear 230; one end of the output shaft 250 is connected to the lower wrench 400, and the other end is connected to the driven bevel gear 240; the driving bevel gear 230 is gear-meshed with the driven bevel gear 240.

[0037] During specific use, the torque is input through the handwheel 300, and the torque is transmitted to the active bevel gear 230 through the input shaft 220. The torque is amplified in a certain proportion by utilizing the gear ratio of the active bevel gear 230 and the driven bevel gear 240. The amplified torque is output from the output shaft 250, driving the lower wrench 400 to rotate with the axis of the output shaft 250 as the rotation center, thereby realizing the transmission of torque.

[0038] In a specific embodiment, the number of the handwheel 300, the input shaft 220, and the active bevel gear 230 is set to at least two respectively. When at least two torque input parts consisting of the handwheel 300, the input shaft 220, and the active bevel gear 230 are set, torque can be input from different angles, and the operation is more convenient.

[0039] The present embodiment does not limit the gear ratio between the driving bevel gear 230 and the driven bevel gear 240 . The driving bevel gear 230 and the driven bevel gear 240 with corresponding gear ratios can be selected according to the size of the vibration isolator body 700 .

[0040] In this embodiment, please refer to the attached Figure 3 and Figure 4 The partition 100 is connected to the reducer housing 210 through a first fixing member 110. The first fixing member 110 is specifically a screw or a bolt, which is threadedly connected to a threaded hole on the reducer housing 210 to fix the partition 100 to the reducer housing 210, so that the partition 10 provides a stable positioning platform for the housing 500 and the vibration isolator body 700.

[0041] In this embodiment, please refer to the attached Figure 6 The lower wrench 400 is connected to the output shaft 250 via a key 420. The connection mode of the lower wrench 400 and the output shaft 250 via the key 420 facilitates the replacement of the lower wrench 400 separately. When the lower wrench positioning rod 610 is damaged, it is not necessary to replace the tooling as a whole, but only to replace partial parts, thereby saving costs.

[0042] In this embodiment, please refer to the attached Figure 6, a housing lower positioning hole 510 is provided at one end of the housing 500, and a second fixing member 120 is provided on the partition 100, and the second fixing member 120 penetrates the housing 500 and is threadedly connected with the housing lower positioning hole 510. The second fixing member 120 is specifically a screw or a bolt, and the housing lower positioning hole 510 is a threaded hole. The housing 500 is fixedly connected to the partition 100 through the second fixing member 120, so that the housing 500 can be replaced according to the size of the vibration isolator body 700, thereby expanding the scope of application.

[0043] It should be noted that this embodiment does not limit the number of positioning holes 510 and second fixing members 120 under the shell. When there are multiple positioning holes 510 and second fixing members 120 under the shell, they can be arranged in a circular manner along the lower end surface of the shell 500. Multiple second fixing members 120 can improve the fixing effect of the shell 500 and prevent the shell 500 from tilting.

[0044] In this embodiment, in order to facilitate the installation of the vibration isolator body 700 into or removal from the shell 500, a lower shell notch 520 is provided at one end of the shell 500, and the lower shell notch 520 is arranged in a staggered manner with the lower shell positioning hole 510. The lower notch 520 connects the inner cavity of the shell 500 with the outside atmosphere, avoiding the formation of a pressure difference on both sides of the vibration isolator body 700 when the vibration isolator body 700 is installed, thereby facilitating the disassembly and assembly of the vibration isolator body 700. At the same time, the lower notch 520 is provided to further reduce the weight of the shell 500, thereby achieving an overall weight reduction effect.

[0045] In this embodiment, please refer to the attached Figure 3 , the other end of the housing 500 is provided with a housing positioning hole 530, and the upper wrench 600 is provided with a third fixing member 630, and the third fixing member 630 passes through the upper wrench 600 and is threadedly connected with the housing positioning hole 530. The third fixing member 630 is specifically a screw or a bolt, and the housing positioning hole 530 is a threaded hole; the third fixing member 630 is screwed into the housing positioning hole 530 to realize the detachable connection between the upper wrench 600 and the housing 500, and at the same time, the end cover 720 on one side of the metal rubber 710 is positioned, and when the torque is transmitted to the lower wrench 400, the relative position between the upper wrench 600 and the end cover 720 on one side is ensured to be fixed, so that the end cover 720 and the cylindrical spring 730 can be disassembled.

[0046] This embodiment does not limit the number of the lower positioning holes 510 and the second fixing members 120 of the shell. Preferably, there are two second fixing members 120, which are respectively located at the two ends of the upper wrench 600. Preferably, there are a plurality of lower positioning holes 510, which are arranged in a ring shape at intervals on the top of the shell 500. During installation, the two second fixing members 120 fix the two ends of the upper wrench 600 to improve the installation stability of the upper wrench 600.

[0047] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
