[0030] To enable those skilled in the art to better understand the technical solutions of the present disclosure, the present disclosure will be further described in detail below with reference to the drawings and specific embodiments.

When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0035] As Figures 1 to 4 shown, the present disclosure provides an assembly tooling 100 for a vacuum pump. The assembly tooling 100 includes: a tooling cart 110, two bottom plate fixing components 120, at least one exhaust pipe baffle limiting member 130, two bottom plates 140, an exhaust pipe baffle 150, and at least one bottom plate connecting plate 160. Among them, the two bottom plate fixing components 120 and at least one exhaust pipe baffle limiting member 130 are disposed on the top of the tooling cart 110, and the two bottom plate fixing components 120 are distributed on both sides of at least one exhaust pipe baffle limiting member 130 along the width direction of the tooling cart 110, that is, the bottom plate fixing components 120 are disposed on both the left and right sides of the exhaust pipe baffle limiting member. Based on this, each bottom plate 140 is fixed to a bottom plate fixing component 120, the exhaust pipe baffle 150 is fixed to at least one exhaust pipe baffle limiting member 130, and the exhaust pipe baffle 150 is simultaneously connected to the two bottom plates 140, and the bottom plate connecting plate 160 is connected to any one side of the two bottom plates 140 along their length direction.

[0036] In this embodiment, by fixing the bottom plate and the exhaust pipe baffle to the tooling cart, and also connecting the bottom plate connecting plate to the two bottom plates, the fixing of the bottom plate assembly in both the longitudinal and transverse directions is realized, the strength of the bottom plate assembly is improved, and the deformation phenomenon is not likely to occur, thereby improving the assembly efficiency of the vacuum pump and meeting the assembly requirements.

[0037] It should be understood that after fixing the two bottom plates to the bottom plate fixing components and fixing the exhaust pipe baffle to the exhaust pipe baffle limiting member, the exhaust pipe baffle can also be fixed to the two bottom plates through fixing members such as bolts to form a bottom plate assembly, and then the bottom plate connecting plate can be installed on the bottom plate assembly through fixing members such as bolts. Based on the high strength of the bottom plate connecting plate and the two bottom plates, the strength of the bottom plate assembly is further improved and the deformation phenomenon is not likely to occur.

[0038] It should be noted that the number of bottom plate connectors in this embodiment is not specifically limited. For example, in some preferred embodiments, the bottom plate connectors can be provided on either side of the two bottom plates. In this case, when installing the front side plate subsequently, the front side plate can be directly installed on the side where the bottom plate connectors are not installed. In some other preferred embodiments, the bottom plate connectors can also be provided on both sides of the two bottom plates. In this case, when installing the front side plate subsequently, one of the bottom plate connectors needs to be disassembled and the front side plate is installed at this position. It should be noted that when installing the front side plate in the above two cases, bottom plate connection plates are provided on the other side of the bottom plate, thereby preventing the bottom plate assembly from deforming and ensuring the vibration performance and assembly consistency of the vacuum pump.

[0039] It should be understood that generally, two feet 141 are provided below the bottom plate 140, as Figure 1 shown, and the height of the feet can be adjusted, which is beneficial to increasing the stability and levelness of the vacuum pump and facilitating the adjustment and fixation of the position of the vacuum pump.

[0040] Furthermore, as Figures 1 to 4 shown, the bottom plate fixing assembly 120 includes a bottom plate fixing member 121 and two foot limiting members 122; wherein, the bottom plate fixing member 121 is used to fix the bottom plate 140, and the two foot limiting members 122 are respectively used to limit the positions of the two feet 141 on the bottom plate 140, and the two foot limiting members 122 are distributed on both sides of the bottom plate fixing member 121 along the length direction of the tooling cart 110. That is to say, the two bottom plates are respectively fixed to the tooling cart through two bottom plate fixing assemblies. Among them, the bottom plate fixing member is used to support the two bottom plates, and the foot limiting member is used to limit the position of the feet. In this way, when the two bottom plates are fixed to the exhaust pipe baffle, the connection holes thereon can be quickly aligned, which is convenient for installing bolts, saving installation time. At the same time, by adjusting the height of the feet, the feet are placed in the foot installation grooves, and the foot ground is in contact with the tooling cart, improving the stability of the bottom plate.

[0041] In some preferred embodiments, as Figures 1 to 3 shown, the bottom plate fixing member 121 includes a first support plate 121a and a second support plate 121b which are oppositely arranged, and a plurality of support columns 121c clamped between the first support plate 121a and the second support plate 121b; the first support plate 121a is connected to the tooling cart 110, and the second support plate 121b is connected to the bottom plate 140.

[0042] It should be understood that in the bottom plate fixing member, only a plurality of threaded holes need to be opened on the first support plate and it can be fixed to the tooling cart through bolts. Similarly, bolts can also be used to fixedly connect the support columns to the first support plate and the second support plate.

[0043] It should be noted that the number of support columns in this embodiment is not specifically limited. For example, two support columns or three support columns can be arranged in the middle area between the first support plate and the second support plate, or four support columns can be evenly arranged in the edge area between the first support plate and the second support plate, etc.

[0044] As a further preferred solution, as Figures 1 to 3 shown, an anti-wear protection member 123 is further provided on the side of the second support plate 121b facing the bottom plate 140 to prevent the bottom plate from wearing the bottom plate fixing member 121. Among them, the anti-wear protection member can be made of materials such as nylon.

[0045] In some other preferred embodiments, as Figures 1 to 3 shown, a plurality of floor mounting grooves 111b are provided on the tooling trolley 110, and a floor limiting member 122 is correspondingly provided for each floor mounting groove 111b. The floor limiting member 122 can surround the periphery of the floor mounting groove 111b, or its bottom can be accommodated in the floor mounting groove 111b. In this way, the floor feet 141 on the bottom plate 140 are in contact with the bottom of the floor mounting groove 111b and are clamped in the floor limiting member 122 to prevent them from sliding.

[0046] It should be understood that the number of floor mounting grooves should be the same as the number of floor feet on the bottom plate. Generally, two floor feet are provided on each bottom plate, and a total of four floor feet are provided on two bottom plates. In this way, a total of four floor mounting grooves need to be provided on the tooling trolley, and a floor limiting member is correspondingly provided for each floor mounting groove.

[0047] As a further preferred solution, the floor limiting member is a limiting ring, that is, the limiting ring is installed on the periphery of the floor mounting groove to limit the position of the floor feet and prevent them from moving.

[0048] Furthermore, as Figures 1 to 3 shown, the exhaust pipe baffle limiting member 130 includes two connecting portions 131 and a limiting portion 132 located between the two connecting portions 131; wherein, threaded holes are provided on the connecting portions 131, and the connecting portions 131 are connected to the tooling trolley 110 through bolts. The limiting portion 132 is recessed from the connecting portion 131 towards the side of the tooling trolley 110. That is to say, the limiting portion and the two connecting portions form a "concave" structure for supporting the exhaust pipe baffle and achieving precise positioning of the installation position of the exhaust pipe baffle.

[0049] It should be noted that the number and size of the exhaust pipe baffle limiters are not specifically limited in this embodiment. Their sizes should match the size of the exhaust pipe baffle. The number can be one, two, three, etc. For example, when there is one exhaust pipe baffle limiter, it should be set at the middle position below the exhaust pipe baffle; for another example, when there are two exhaust pipe baffle limiters, they should be set at the two edge positions below the exhaust pipe baffle. Of course, other numbers of exhaust pipe baffle limiters can also be set.

[0050] Furthermore, as Figures 1 to 3 shown, the bottom plate 140 is provided with at least one shock absorption component, and the shock absorption component includes a shock absorption pad 142 and a caster 143 connected to each other; wherein, the shock absorption pad 142 is arranged above the bottom plate 140, the caster 143 is arranged below the bottom plate 140, and there is a gap between the caster 143 and the tooling trolley 110. That is to say, the caster does not contact the tooling trolley, and it plays a role in reducing vibration and noise during the assembly of the vacuum pump body.

[0051] It should be noted that the number of the shock absorption components is not specifically limited in this embodiment. One shock absorption component can be arranged on each bottom plate, two shock absorption components can also be arranged, and of course, three shock absorption components can also be arranged, etc.

[0052] It further needs to be noted that the structure of the tooling trolley is not specifically limited in this embodiment, as long as it can fix the bottom plate and the exhaust pipe baffle. For example, the tooling trolley includes a top plate and a bottom support frame. It should be noted that the bottom support frame should be formed by connecting a plurality of horizontal support columns and a plurality of vertical support columns, that is, there is a hollow area between the bottom support frame and the top plate, which not only plays a role in supporting the top plate, but also helps to provide an operation space when the bottom plate fixing component, the exhaust pipe baffle limiter and the tooling trolley are fixedly connected.

[0053] It still needs to be noted that in order to meet the assembly requirements of different pump models, at least one set of installation parts corresponding to at least one model of vacuum pump can be arranged on the tooling trolley, as Figures 1 to 3As shown, each set of installation parts 111 includes two fixed component installation parts, at least one limit piece installation part 111a, and two anchor installation grooves 111b. Among them, the exhaust pipe baffle limit piece 130 is installed on the limit piece installation part 111a. The fixed component installation part includes a bottom plate fixed piece installation part 111c and an anchor limit piece installation part 111d. The bottom plate fixed piece 121 in each bottom plate fixed component 120 is installed on the bottom plate fixed piece installation part 111c. The anchor limit piece 122 surrounds the periphery of the anchor installation groove 111b and is installed in the anchor limit piece installation part 111d. The anchor 141 on the bottom plate 140 is installed in the anchor installation groove 111b, and the anchor 141 is also clamped in the anchor limit piece 122 at the same time. That is to say, one set of installation parts is used to install the bottom plate fixed component and the exhaust pipe baffle limit piece, and the other set or multiple sets of installation parts are used as spares. According to the pump type of the vacuum pump, the installation parts with matching dimensions are selected for assembly.

[0054] It should also be understood that the dimensions of the installation parts in the standby state and the installation parts in the use state can be different to meet the installation of different pump types, and the applicability is stronger. When it is necessary to use the installation parts in the standby state, the bottom plate fixed component and the exhaust pipe baffle limit piece are disassembled from the installation parts in the use state and installed on the corresponding standby installation parts. Of course, according to the dimensions of the installation parts, other structures such as bottom plate fixed components and exhaust pipe baffle limit pieces with different dimensions can be selected and installed on the corresponding installation parts. That is to say, by adjusting the installation positions of the bottom plate fixed component and the exhaust pipe baffle limit piece, the assembly requirements of multiple pump types can be met.

[0055] It should be noted that the present embodiment does not specifically limit the installation method of the bottom plate fixed component on the fixed component installation part and the installation method of the exhaust pipe baffle limit piece on the limit piece installation part. Bolting can be used, or snap fixation and other methods can be used. It is not difficult to understand that when using bolting, the fixed component installation part and the limit piece installation part provided on the tooling trolley should be threaded holes, and the bottom plate fixed component and the exhaust pipe baffle limit piece are sequentially installed in the corresponding threaded holes through bolts.

[0056] It still needs to be noted that in order to facilitate the movement of the tooling trolley, a plurality of sliding parts can be provided at the bottom of the tooling trolley, and the plurality of sliding parts are evenly distributed around the periphery of the bottom support frame. For example, as Figures 1 to 4 shown, one sliding part 112 is provided at each of the four sides of the bottom support frame of the tooling trolley 110. Of course, the present embodiment does not specifically limit the type of the sliding part. For example, casters can be used to move along with the transfer of the assembly process.

[0057] It still needs to be noted that in order to further control the tooling trolley, as Figures 1 to 4As shown, at least one braking member 113 can be provided at the bottom of the tooling cart 110. In this way, when the tooling cart 110 needs to stop, it can be braked and stopped by the braking member 113 to prevent it from sliding randomly and improve stability. Of course, in this embodiment, the type of the braking member is not specifically limited either. For example, brake pads can be used.

[0058] Furthermore, as Figure 4 shown, after the assembly tooling is fixed, one of the bottom plate connecting plates 160 is disassembled, and the front side plate 210 is installed at this position, or the front side plate is installed on the side where the bottom plate connecting plate is not installed. Then, the DP pump body 220 is installed on the shock pad 142 of the bottom plate assembly. Based on the structure of the above-mentioned assembly tooling, when installing the DP pump body, the bottom plate assembly will not be deformed, ensuring the vibration performance and assembly consistency of the vacuum pump, and improving the operation efficiency at the same time.

[0059] The structure of the assembly tooling for the vacuum pump will be further described below with specific embodiments:

In addition, an exhaust pipe baffle 150 is arranged between the two exhaust pipe baffle limiters 130. At the same time, the exhaust pipe baffle 150 is fixedly connected to the two bottom plates 140 in the horizontal direction by bolts.

[0066] Please continue to refer to Figures 1 to 4 , two bottom plate connecting plates 160 are respectively connected to the two sides of the two bottom plates 140 by bolts.

[0067] Furthermore, please continue to refer to Figures 1 to 4 , when assembling the vacuum pump, one of the bottom plate connecting plates 160 needs to be removed first, and a front side plate 210 is installed at this position.
