Description

Technical Field

[0001] The utility model relates to the technical field of steel structure building construction, in particular to a novel flexible manufacturing tool for a space structure. Background Art

[0002] In the process of modern steel structure construction, the segmented construction method is usually used. The structural manufacturer will divide the spatial structure into several parts and manufacture them separately, that is, split it into multiple segmented components. After each segmented component is manufactured, the multiple segmented components are combined together to create a huge structure.

[0003] The tooling is an important tool for completing the closing process. It is used to support each segmented component during the closing process, so that each segmented component can maintain a good position and provide good conditions for the assembly and welding of two adjacent segmented components.

[0004] Among them, the spatial structures can be roughly divided into structures for small and medium-sized spaces and structures for large spaces. For small and medium-sized spatial structures, the linear changes of the structure are large, and the structural steel plates are relatively thin. The tooling is required to have sufficient strength and rigidity to control the appearance of each segmented component to reduce the welding deformation of the segmented component after it is separated from the tire frame. For large spatial structures, the linear changes of the structure are small, the structural steel plates are thick, and the role of the tire frame as a device for forcibly controlling welding deformation is significantly reduced. Its main role is to support the gravity of the segment. As is well known, the structure used for large spaces mainly relies on the structural strength of the structure itself to avoid deformation of each segmented component after it is separated from the tire frame, while the structure used for small and medium-sized spaces often requires tooling to avoid deformation of each segmented component after it is separated from the tire frame. In the prior art, the tooling often has a single function, poor matching, and is time-consuming and labor-intensive to use. It is necessary to manually set the fulcrum height one by one according to the data calculated in advance, which is not conducive to improving assembly efficiency. Utility Model Content

[0005] The utility model discloses a new type of flexible manufacturing tooling for spatial structures, which solves the technical problems in the prior art that the tooling has a single function, is time-consuming and labor-intensive to operate, and is not conducive to improving assembly efficiency, and has the technical advantages of reasonable structure, convenient operation, good applicability and low maintenance cost. The technical solution adopted is as follows:

[0006] A novel flexible manufacturing tool for spatial structures includes a support body, on which a plurality of support components are arranged, and the support components include a mounting seat, a drive unit, a push rod and a controller. The mounting seat is arranged on the support body, and the drive unit and the controller are fixed to the mounting seat. The drive unit can drive the push rod to move up and down to support the segmented component upward, and the drive unit is electrically connected to the controller.

[0007] On the basis of the above technical solution, the support body is a frame structure and includes a plurality of legs, the support components are arranged on the legs, and the plurality of support components are evenly arranged.

[0008] On the basis of the above technical solution, the bracket body includes a plurality of detachably connected frame units, and the frame units are frame structures.

[0009] On the basis of the above technical solution, the top end of the push rod is ball-hinged upward with a positioning plate, and the positioning plate can fit upward with the segmented component at an adaptive angle.

[0010] On the basis of the above technical solution, it also includes a pressure sensor. The driving unit includes a piston rod, and the piston rod is coaxially fixed to the push rod upward through the pressure sensor. The pressure sensor is used to monitor the axial force of the push rod and is electrically connected to the controller.

[0011] On the basis of the above technical solution, it also includes a second sensor, which is fixed on the bracket body and is used to monitor the displacement stroke of the push rod. The second sensor is electrically connected to the controller.

[0012] Based on the above technical solution, it also includes a guide rod, which is arranged parallel to the push rod and fixedly connected to the push rod through a connecting rod. A flat plate is fixed on the mounting seat, and a through hole is provided on the flat plate for the guide rod to pass through, so as to guide the push rod.

[0013] On the basis of the above technical solution, it also includes a corbel, which is fixedly connected to the mounting seat upwards, and the upper and lower positions of the corbel are adjustable and connected to the bracket body.

[0014] Beneficial Effects

[0015] The utility model has a reasonable structure, and multiple supporting components are evenly arranged on the bracket body. It has a wide range of applications and can be used to support segmented components of various shapes and structures. In addition, a controller is also provided to automatically adjust the displacement of the push rod according to the position of the segmented component.

[0016] In this embodiment, the guide rod can guide the push rod to ensure the stability of the push rod displacement. In addition, a bracket is provided, and the upper and lower positions of the bracket are adjustable and connected to the mounting seat. When the push rod reaches the upper limit and still cannot support the segmented component, the support can be achieved by adjusting the position of the bracket, which is flexible and convenient to use. In addition, the bracket body includes multiple frame units, which can be combined and assembled according to the use requirements, which is convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] like Figures 1-2 A new type of spatial structure flexible manufacturing tooling shown includes a bracket body 1, which includes a plurality of detachably connected frame units 11. The frame unit 11 is a frame structure and includes a plurality of legs. In this embodiment, the frame unit 11 includes a top square frame, and legs are fixedly connected to the bottom of the square frame. Support assemblies 2 are provided on the legs, and the plurality of support assemblies 2 are evenly arranged.

[0026] like Figure 2 As shown, the support assembly 2 includes a mounting base 21, a driving unit 22, a push rod 23 and a controller 24. The several controllers 24 are electrically connected to the external master controller 100 respectively. The mounting base 21 is L-shaped. A corbel 3 is fixedly connected downward to the mounting base 21. The corbel 3 is connected to the leg of the bracket body 1 in an adjustable manner in terms of up and down positions. Specifically, the leg is provided with a plurality of vertically arranged threaded holes. The screw assembly passes through the corbel 3 and is screwed to the threaded holes to fix the corbel 3 and the leg.

[0027] The drive unit 22 and the controller 24 are fixed on the mounting base 21. In this embodiment, the drive unit 22 includes an electric push rod fixed on the mounting base 21. The electric push rod is a prior art, and those skilled in the art can purchase it according to their needs. The piston rod of the electric push rod is coaxially fixed with the push rod 23 upward through the pressure sensor 26. The pressure sensor 26 is used to monitor the axial force of the push rod 23 and is electrically connected to the controller 24. The pressure sensor 26 is a prior art and will not be repeated here. When the pressure sensor 26 has no feedback signal to the controller 24, the controller 24 can determine that this is a virtual position, that is, the push rod 23 here does not support the segmented component well, and sends an alarm signal. In addition, a second sensor (not shown) is also included. In this embodiment, the second sensor includes a grating, which is fixed on the mounting base 21 and electrically connected to the controller 24. The grating can send a signal to the controller 24 for monitoring the displacement stroke of the push rod 23.

[0028] like Figure 2 As shown, the top end of the push rod 23 is ball-jointed with a positioning plate 25, which includes a circular top end surface that can contact the surface of the component. When the push rod 23 is displaced to a set position, the positioning plate 25 can adaptively fit upward at an angle with the segmented component to provide stable support.

[0029] In addition, it also includes a guide rod 28, which is arranged parallel to the push rod 23 and fixedly connected to the push rod 23 through a connecting rod. A flat plate is fixedly arranged on the mounting seat 21, and a through hole is arranged on the flat plate for the guide rod 28 to pass through so as to guide the push rod 23.

[0030] Working process

[0031] First, place each segmented component on the tooling. Figure 1 As shown, the main controller 100 sends a signal to the controller 24 of the support component 2 to be worked, and the controller 24 controls the driving unit 22 at the corresponding position to control the displacement of the push rod 23. At the same time, the second sensor sends a signal of the displacement of each push rod 23 to the controller 24. The controller 24 detects whether the displacement of each push rod 23 is consistent with the set initial displacement data. When the initial displacement data exceeds the upper or lower limit of the actual displacement of the push rod 23, the height of the corbel 3 can be adjusted to well support the component. In addition, the pressure sensor 26 will send a signal to the controller 24 in real time. When the controller 24 detects that the axial pressure on the push rod 23 after displacement is less than the set value, the controller 24 adjusts the action of the driving unit 22, and then adjusts the displacement of the push rod 23. In this way, the component can be supported at multiple positions to ensure that the component is placed firmly.

[0032] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments, and any changes or modifications based on the present invention belong to the scope of protection required by the present invention.
