Abstract
Description
Technical Field
[0001] This utility model relates to the field of vacuum pump technology. Background Technology
[0002] The IQDP80 vacuum pump is a common type of pump in the industry. Driven electrically, it is suitable for various industrial applications requiring high vacuum environments, such as semiconductor manufacturing, photovoltaic equipment, lithium battery production, laboratories, and factories. Employing a screw-type design, it features high efficiency and stability, enabling it to achieve high vacuum levels.
[0003] However, while its compact design occupies little space and is easy to set up and install, its daily maintenance or disassembly presents challenges. The front cover is difficult to remove because the bearings on the front cover are fixed to the shaft. Furthermore, due to the pump's considerable weight, disassembly often requires hoisting or the use of multiple clamps for fixation, and a push rod is used to separate the cover from the pump shaft. The separated cover, due to its weight, is easily damaged during separation. Existing disassembly tools are often incompatible with the compact structure of the IQDP80 vacuum pump, resulting in low disassembly efficiency and a high risk of component damage. Utility Model Content
[0004] The purpose of this utility model is to provide an IQDP80 vacuum pump disassembly fixture in order to solve the above-mentioned technical problems.
[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0006] A disassembly fixture for an IQDP80 vacuum pump includes a mounting plate. The mounting plate has a first positioning rod and a second positioning rod at both ends. The lower end of the first positioning rod is rotatably connected to a first positioning plate, and the lower end of the second positioning rod is rotatably connected to a second positioning plate. Both the first positioning plate and the second positioning plate are provided with positioning and stabilizing components. The mounting plate is provided with a push rod. The outer circumference of the push rod is threaded and screwed to the mounting plate. The position of the push rod is directly opposite the pivot of the front cover plate of the vacuum pump.
[0007] With the above solution, during disassembly, the first and second positioning plates are aligned with the front cover of the vacuum pump, and the tooling is fixed to the front cover by connecting the screw holes of the front cover with the positioning and stabilizing components. Simultaneously, the mounting plate is fixed to the first and second positioning rods with bolts. At this point, the push rod is aligned with the rotating shaft on the front cover. Then, the push rod is rotated sequentially to push the rotating shaft out of the bearing. The entire front cover can then be lifted, and the tooling can be disassembled to separate the rotating shaft from the bearing, thus separating the front cover from the pump body. The entire process is simple to operate. Furthermore, the first and second positioning plates, in conjunction with the push rod, limit the movement of the workpiece, preventing collisions. The large contact area between the first and second positioning plates and the front cover disperses the supporting force, preventing damage to the cover surface. The entire process greatly improves the disassembly efficiency of the vacuum pump and facilitates repair and maintenance.
[0008] Furthermore, the positioning and stabilizing component includes positioning screw holes that are adapted to the mounting screw holes of the vacuum pump front cover plate on both the first positioning plate and the second positioning plate, and a positioning bolt adapted to the positioning screw holes.
[0009] The above solution uses positioning bolts to fasten the first positioning plate, the second positioning plate, and the front cover of the vacuum pump, which is convenient and does not require additional drilling.
[0010] Furthermore, the top of the push rod is provided with a rotating part, which can be any one of a hexagonal stud, an internal hexagonal stud, or a slotted countersunk stud.
[0011] The above scheme incorporates a rotating part, making it easier to rotate using tools.
[0012] Furthermore, there are two push rods, and the distance between the two push rods is the same as the distance between the two rotating shafts of the vacuum pump front cover plate.
[0013] The above solution involves setting two top rods to facilitate the sequential disassembly of the rotating shaft.
[0014] Furthermore, gaskets are provided on the lower end faces of the first positioning plate and the second positioning plate.
[0015] The above solution, by adding a gasket, further prevents scratches on the cover plate.
[0016] Furthermore, the lower end of the push rod is spherical.
[0017] The above solution reduces the damage to the rotating shaft caused by rotation at the lower end of the spherical push rod.
[0018] The beneficial effects of this utility model are as follows:
[0019] 1. This utility model has a simple structure. During disassembly, the first and second positioning plates are aligned with the front cover of the vacuum pump. The tooling is fixed to the front cover of the pump body by connecting the screw holes of the front cover of the vacuum pump through the positioning and stabilizing parts. At the same time, the mounting plate is fixed to the first and second positioning rods with bolts. At this time, the push rod is aligned with the rotating shaft on the front cover. Then, the push rod is rotated in sequence to push the rotating shaft out of the bearing. Then, the entire front cover can be lifted. After that, the tooling is disassembled to separate the rotating shaft from the bearing and separate the front cover from the pump body. The whole process is simple to operate. At the same time, due to the limiting of the first and second positioning plates and the push rod, the workpiece is not bumped. The contact area between the first and second positioning plates and the front cover is large, which disperses the supporting force and avoids damage to the cover plate surface. The whole process greatly improves the disassembly efficiency of the vacuum pump and facilitates maintenance. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0024] Example 1
[0025] like Figure 1As shown, this embodiment provides a disassembly fixture for an IQDP80 vacuum pump, including a mounting plate 11. A first positioning rod 12 and a second positioning rod 13 are provided at both ends of the mounting plate 11. A first positioning plate 14 is rotatably connected to the lower end of the first positioning rod 12, and a second positioning plate 15 is rotatably connected to the lower end of the second positioning rod 13. Positioning and stabilizing members 16 are provided on both the first positioning plate 14 and the second positioning plate 15. A push rod 17 is provided on the mounting plate 11. The outer periphery of the push rod 17 is threaded and screwed to the mounting plate 11. The position of the push rod 17 is directly opposite the rotating shaft of the front cover plate of the vacuum pump.
[0026] With the above solution, during disassembly, the first positioning plate 14 and the second positioning plate 15 are aligned with the front cover of the vacuum pump. The positioning and stabilizing parts 16 are connected to the screw holes of the front cover of the vacuum pump to fix the tooling to the front cover of the pump body. At the same time, the mounting plate 11 is fixed with the first positioning rod 12 and the second positioning rod 13 by bolts. At this time, the push rod 17 is aligned with the rotating shaft on the front cover. Then, the push rod 17 is rotated in sequence to push the rotating shaft out of the bearing. Then, the entire front cover can be lifted. After that, the tooling is disassembled to separate the rotating shaft from the bearing and to separate the front cover from the pump body. The whole process is simple to operate. At the same time, because the first positioning plate 14 and the second positioning plate 15 cooperate with the limit of the push rod 17, the workpiece is not bumped. The first positioning plate 14 and the second positioning plate 15 have a large contact area with the front cover, which disperses the supporting force and avoids damage to the cover plate surface. The whole process greatly improves the disassembly efficiency of the vacuum pump and facilitates maintenance.
[0027] To reduce damage to the workpiece, refer to Figure 1 Gaskets (not shown in the drawings) are provided on the lower end faces of the first positioning plate 14 and the second positioning plate 15. These gaskets further prevent scratching of the cover plate. The lower end of the push rod 17 is spherical. The spherical shape of the lower end of the push rod 17 reduces damage to the rotating shaft during rotation.
[0028] To further achieve stable disassembly, simplify operation steps, and improve the adaptability of the device, refer to Figure 1 The positioning and stabilizing component 16 includes positioning screw holes 18 on both the first positioning plate 14 and the second positioning plate 15, which are adapted to the mounting screw holes of the vacuum pump front cover. A positioning bolt 19, adapted to the positioning screw holes 18, is also provided. The positioning bolt 19 is used to fasten the first positioning plate 14, the second positioning plate 15, and the vacuum pump front cover, making fixing convenient and requiring no additional drilling. The top of the push rod 17 has a rotating part 20, which can be any of a hexagonal stud, an internal hexagonal stud, or a countersunk stud. In this embodiment, a hexagonal stud is used as the rotating part 20, which facilitates rotation using tools. There are two push rods 17, with the distance between them being the same as the distance between the two rotating shafts of the vacuum pump front cover. The two push rods 17 facilitate sequential disassembly of the rotating shafts.
[0029] It should be noted that the connection relationships of components not specifically mentioned in this application are all assumed to be based on existing technology. Since they do not involve the inventive point and are commonly used in existing technology, the structural connection relationships are not described in detail.
