Detailed implementation manners

[0027] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Those not specified in the embodiments are carried out according to conventional conditions or conditions recommended by the manufacturer. Those reagents or instruments not specified by the manufacturer can be obtained as conventional products through commercial purchase.

[0028] The modular combined paving platform provided by the present invention and its application will be specifically described below.

[0029] The present invention provides a modular combined paving platform, as Figure 1 shown, the modular combined paving platform includes a foundation bolt 20 of the platform unit and at least two platform unit components 30.

[0030] Each platform unit component 30 includes an upper panel 31 and a lower panel 33 of the platform that are relatively spaced apart, and a support member is connected between the upper panel 31 and the lower panel 33 of the platform; a vent hole 34 is provided on the upper panel 31 of each platform unit component 30, and a vent sacrificial layer 36 is provided on the upper surface of the upper panel 31 of each platform unit component 30; an air guide hole 35 for connecting an air suction pipeline is provided on the lower panel 33 of each platform unit component 30; a foundation bolt 20 of the platform unit is connected to the lower panel 33 of each platform unit component 30;

[0031] Two adjacent platform units are docked by a docking mechanism.

[0032] The modular combined paving platform provided by the present invention can avoid the operation of leveling again every time the tooling is moved or recombined, which can not only reduce the foundation cost, but also save time and effort; the modular combined paving platform can be combined and placed in different forms according to needs, improving the expandability of the paving platform work; in addition, the modular combined paving platform can realize the rapid connection of the paving surface and the air circuit, with high efficiency.

[0033] In some alternative implementation manners, the foundation bolt 20 of the platform unit is placed on the foundation bolt placement point 11 that has been reinforced and leveled on the ground.

[0034] During specific operations, specific points can be selected on the workshop floor and set as the foundation footing placement points 11. The foundations 10 corresponding to each foundation footing placement point 11 are strengthened to meet the load-bearing requirements. Moreover, the floor is leveled. This leveling foundation for the matrix platform can greatly reduce the foundation cost.

[0035] Exemplarily, the number of foundation footing placement points 11 set on the ground is 4×4, that is, the foundation footing placement points 11 are arranged in an array, specifically including 4 rows and 4 columns, and each row and each column are provided with 4 foundation footing placement points 11. As Figure 2 shown, a single platform foundation footing placement point 11 can be square, and its side length ( Figure 2 represented by "d" in the figure) can be 400 mm; the lateral (row direction) spacing between two adjacent platform foundation footing placement points 11 ( Figure 2 represented by "W" in the figure) can be 1500 mm, and the longitudinal (column direction) spacing between two adjacent platform foundation footing placement points 11 ( Figure 2 represented by "L" in the figure) can be 2500 mm. In other embodiments, the number of foundation footing placement points 11 set on the ground can be adjusted according to actual needs, and no special limitation is made here.

[0036] In some alternative embodiments, the number of platform unit components 30 in the modular combined paving platform can be 2, 3, 4, 5, 6 or more, and is specifically set according to actual needs.

[0037] As an example, taking the number of platform unit components 30 in the modular combined paving platform as 6, these 6 platform unit components 30 can be paved in the way of horizontal quantity × vertical quantity being 2×3 (as Figure 3 shown), or can be paved in the way of horizontal quantity × vertical quantity being 3×2 (as Figure 4 shown). In other words, the platform unit feet 20 of each platform unit component 30 match the size of the foundation footing placement points 11, and the platform unit components 30 can be combined in different combination forms according to requirements to meet different paving needs.

[0038] In some alternative embodiments, the platform unit feet 20 are provided with a height adjustment device for adjusting the height of the platform unit. Exemplarily, adjustment can be performed through a height adjustment knob 21 or a threaded structure.

[0039] In the present invention, the structure of the platform unit component 30 can be understood as being similar to a "sandwich" structure. Both ends of the support member are respectively connected to the platform upper panel 31 and the platform lower panel 33 to provide support force for the platform unit component 30. The number of support members can be set according to actual needs. As an example, the support member can be a rib plate 32, or can also be a reinforcing rib or other structures that can play an effective supporting role.

[0040] In the present invention, an air-permeable sacrificial layer 36 is provided on the upper surface of the platform upper panel 31 of each platform unit 30. During specific paving, the side provided with the air-permeable sacrificial layer 36 serves as the paving working surface. The air-permeable holes 34 provided on the platform upper panel 31 of each platform unit 30 are conducive to realizing the rapid connection between the paving working surface and the gas path.

[0041] In the present invention, the docking mechanism includes a mutually mating first docking structure 41 and a second docking structure 42. The first docking structure 41 and the second docking structure 42 are respectively arranged on the docking surfaces of two platform units to be docked.

[0042] The above-mentioned "mutually mating" can also be understood as "male-female pairing" to facilitate modular docking and achieve the tight fitting of the platform unit 30.

[0043] In some alternative embodiments, the first docking structure 41 can be a groove, and the second docking structure 42 can be a protrusion that is mutually mated with the above-mentioned "groove". By inserting the protrusion into the matching groove, the docking of the two platform units can be achieved. Among them, the bottom edge of the groove can be regarded as the female edge, and the top edge of the protrusion can be regarded as the male edge, and the male edge is mated with the female edge for docking.

[0044] In some alternative embodiments, the protrusion can also be provided with a scale or color. For example, a scale can be directly set on the protrusion, or different colors can be directly set at different positions on the protrusion along the direction of inserting into the groove to be used for confirming the relative position and the extrusion state when the platform unit 30 is docked. In addition, a barcode 43 with a scale or color differentiation can also be set on the protrusion to achieve a similar effect.

[0045] In some alternative embodiments, a sealing material, such as hard rubber 44, etc., is also filled between adjacent two platform units. By filling the sealing material, it can prevent gas from entering from the joint when the modular combined paving platform is in the working state, and improve the adsorption quality of the platform.

[0046] In the present invention, the modular combined paving platform further includes an air suction pipeline, and the air suction pipeline is used to provide a negative pressure condition for the modular combined paving platform. The air suction pipeline includes a first vacuum adsorption pipe 51 and a second vacuum adsorption pipe 52, and the first vacuum adsorption pipe 51 and the second vacuum adsorption pipe 52 are connected by a detachable joint 53.

[0047] The detachable joint 53 is plugged between the first-stage vacuum adsorption tube 51 and the second-stage vacuum adsorption tube 52 as needed. When the air pipe of the detachable joint 53 is plugged between the first-stage vacuum adsorption tube 51 and the second-stage vacuum adsorption tube 52, the entire air suction pipeline is in a conducting state; when the air pipe of the detachable joint 53 is removed from between the first-stage vacuum adsorption tube 51 and the second-stage vacuum adsorption tube 52, the entire air suction pipeline is in a disconnected state.

[0048] Continuing from the above, the modular combined paving platform provided by the present invention has at least the following advantages:

[0049] (1) Making matrix-type local treatment of the factory floor and the foundation 10 according to requirements, with low cost;

[0050] (2) The feet 20 of the platform unit match the size of the placement points 11 of the feet of the factory building, and can be placed in different forms of combination according to requirements, improving the expandability of the paving platform work;

[0051] (3) The platform unit parts 30 have a fast docking structure, and can realize the fast connection of the paving working surface and the air circuit, with high efficiency;

[0052] (4) Having an air leakage prevention structure adjustment mark (such as a barcode 43 with a scale or color), realizing efficient adjustment of air tightness.

[0053] (5) Being able to solve the problems of cumbersome paving work process, low efficiency, high cost, etc. in the manufacturing process of large composite structural parts at present.

[0054] Correspondingly, the present invention also provides an application of the above modular combined paving platform. For example, using the modular combined paving platform for manufacturing aircraft composite structural parts can improve manufacturing efficiency and reduce manufacturing costs.
