Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sheet processing, in particular to a large-size sheet processing platform. BACKGROUND

[0002] Plate members are common components of mechanical equipment, especially large-scale equipment, and with the development of industries such as special manufacturing equipment and large scientific experimental devices, the demand for large-size high-precision sheets is increasing. Such plate members have high requirements in terms of roughness, flatness, straightness, etc., and are difficult to process and prepare.

[0003] Large-size high-precision sheets have the problem of difficult deformation control during the manufacturing process. Specifically, due to the structure and weight of large-size sheets, deformation is likely to occur during machining, turning, and heat treatment, making it difficult to control precision. This deformation affects the precision requirements of the sheet in terms of roughness, flatness, straightness, etc., greatly increasing the difficulty of processing and preparation. SUMMARY

[0004] The problem to be solved by the present application is how to ensure the processing quality of large-size sheets.

[0005] The present application provides a large-size sheet processing platform, comprising a base, an upper seat, a turning leg, a turning connection assembly, and a pressing plate assembly. The base and the upper seat are hinged through the turning connection assembly. When the upper seat is above the base, a fastener is arranged between the base and the upper seat. The upper seat includes a support plane for supporting the sheet. The pressing plate assembly is connected to the upper seat for fixing the sheet. The turning connection assembly is used to turn the upper seat with the sheet relative to the base after removing the fastener. The turning leg is connected to the upper seat for supporting the upper seat after turning relative to the base.

[0006] The large-size sheet tooling platform provided by the present application has the following beneficial effects, but is not limited to: the base can be a rectangular structure, serving as the basic support structure of the entire tooling platform, providing a rigid load-bearing frame for the entire platform, ensuring that the sheet will not be unevenly stressed due to foundation settlement or shaking during sheet machining (such as milling or grinding). The turnover connecting assembly is arranged between the upper seat and the base, forming, for example, a single-side hinge, and when the upper seat is above the base, a fastener such as a threaded connector can also be arranged between the two to ensure the stability of the upper seat. The upper seat has a support plane, and the tooling platform as a whole can form an integrated support surface for placing the sheet for machining. The flat surface of the upper seat directly contacts the sheet to disperse the bending stress generated by the weight of the sheet, avoiding plastic deformation of the sheet due to local suspension, thereby ensuring the flatness and straightness after machining. The upper seat drives the sheet to turn over relative to the base on one side to achieve stable turnover of the sheet. Compared with the traditional hoisting turnover method, the stress concentration point during the turnover of the sheet can be converted into evenly distributed hinge force, avoiding wrinkles or warping of the sheet edges caused by hoisting and pulling. At the same time, the pressing plate assembly arranged on the upper seat is used to apply pressure to the sheet towards the upper seat, so that the sheet closely fits the support surface of the upper seat, ensuring the stability of the sheet when it is set on the upper seat for machining and when the upper seat drives the sheet to turn over relative to the base. The turnover leg is connected to the upper seat, and after the upper seat drives the sheet to turn over on one side relative to the base, the turnover leg rigidly abuts, for example, a machining plane such as the ground, stably supporting the upper seat and transmitting the torque generated by the weight of the sheet to the ground, preventing the upper seat from tilting or vibrating due to gravity shift during turnover, especially suitable for scenarios requiring double-sided machining (such as double-sided grinding or double-sided welding), reducing precision loss caused by improper turnover. Through the coordinated design of support, turnover, and fixation, the present application comprehensively improves the stability of large-size high-precision sheets in the entire manufacturing process, effectively reduces the precision loss caused by deformation, and ensures the machining quality.

DETAILED DESCRIPTION

[0018] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

For those skilled in the art, the specific meaning of the above terms in the application can be understood according to the specific circumstances.

[0021] In the description of the present application, the description of the terms "embodiment", "one embodiment" and "one implementation" means that the specific features, structures, materials or characteristics described in connection with the embodiment or implementation are included in at least one embodiment or implementation of the present application. In the present application, the illustrative description of the above terms does not necessarily refer to the same embodiment or implementation. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or implementations in a suitable manner.

[0022] As shown in Figures 1 to 8 A tooling platform for large-size thin plates according to an embodiment of the present application includes a base 1, an upper seat 2, a turnover leg 3, a turnover connecting assembly 4 and a pressing plate assembly 5. The base 1 and the upper seat 2 are hinged through the turnover connecting assembly 4. When the upper seat 2 is above the base 1, a fastener is further arranged between the base 1 and the upper seat 2. The upper seat 2 includes a support plane for supporting a thin plate. The pressing plate assembly 5 is connected to the upper seat 2 for fixing the thin plate. The turnover connecting assembly 4 is used to turn over the upper seat 2 with the thin plate relative to the base 1 after the fastener is removed. The turnover leg 3 is connected to the upper seat 2 for supporting the upper seat 2 after the upper seat 2 is turned over relative to the base 1.

[0023] In the embodiment, the base 1 refers to a rectangular structure as the basic support structure of the whole tooling platform, providing a rigid bearing frame for the whole platform, ensuring that the thin plate will not be subjected to uneven stress due to foundation settlement or shaking during thin plate machining (such as milling and grinding). The turnover connecting assembly 4 is arranged between the upper seat 2 and the base 1 to form, for example, a single-side hinge, and when the upper seat 2 is above the base 1, fasteners such as threaded connectors can also be arranged between the two to ensure the stability of the upper seat 2. The upper seat 2 has a support plane, and the tooling platform as a whole can form an integrated support plane for placing the thin plate for machining. The flat surface of the upper seat 2 directly contacts the thin plate to disperse the bending stress generated by the self-weight of the thin plate, avoiding plastic deformation of the thin plate due to local suspension, thereby ensuring the flatness and straightness after machining. The upper seat 2 drives the thin plate to be single-side overturned relative to the base 1 to realize stable overturning of the thin plate. Compared with the traditional hoisting overturning method, the stress concentration point in the overturning process of the thin plate can be converted into uniformly distributed hinge force, avoiding wrinkles or warping of the thin plate edge due to hoisting tension. At the same time, the pressing plate assembly 5 arranged on the upper seat 2 is used to apply pressure to the thin plate towards the upper seat 2, so that the thin plate closely adheres to the support plane of the upper seat 2, ensuring the stability of the thin plate when the thin plate is arranged on the upper seat 2 for machining and when the upper seat 2 drives the thin plate to be overturned relative to the base 1, avoiding deformation of the thin plate. The turnover leg 3 is connected to the upper seat 2, and when the upper seat 2 drives the thin plate to be single-side overturned relative to the base 1, the turnover leg 3 is rigidly connected to the machining plane such as the ground, supporting the upper seat 2 and transmitting the torque generated by the self-weight of the thin plate to the ground, preventing the upper seat from tilting or vibrating due to gravity center deviation during overturning, especially suitable for scenarios requiring double-sided machining (such as double-sided grinding and double-sided welding), reducing the precision loss caused by improper overturning. Through the coordinated design of support, overturning and fixation, the stability of large-size high-precision thin plates in the whole manufacturing process is comprehensively improved, the precision loss caused by deformation is effectively reduced, and the machining quality is ensured.

[0024] It should be noted that, as shown in Figure 8 When the thin plate is in the state of machining, heat treatment or transportation, the turnover leg 3 and the turnover connecting assembly 4 do not need to be installed.

[0025] Optionally, the base 1 comprises a base frame 11, a first connecting plate 12 and a first support seat 13. The first connecting plate 12 is connected above the base frame 11 and serves as an interface connected with the upper seat 2. The first support seat 13 is connected to the side wall of the base frame 11 and is used to install the turnover connecting assembly 4.

[0026] Specifically, as shown in Figure 2As shown, the base frame 11 comprises a rectangular frame, and a plurality of base bottom plates can be further arranged on the base frame 11 to form a base plane structure. The first connecting plates 12 are arranged on the base frame 11 in a spaced manner, and the two ends of each first connecting plate 12 are provided with threaded connection holes. The upper seat 2 can be detachably connected with the base 1 through the first connecting plates 12.

[0027] Optionally, the upper seat 2 comprises an upper seat frame 21, second connecting plates 22 and second support seats 23. The second connecting plates 22 are connected to the end face of the upper seat frame 21 facing the base frame 11, and the second connecting plates 22 and the first connecting plates 12 are used to be connected through the fasteners. The second support seats 23 are symmetrically connected to the two sides of the upper seat frame 21, and the second support seats 23 are used to mount the pressing plate assembly 5.

[0028] Specifically, as shown in the drawings, Figure 3 The upper seat frame 21 comprises a rectangular frame to provide a mounting base for each structure. The second connecting plates 22 are arranged in a plurality of spaced-apart manner on the upper seat frame 21, and the two ends of each second connecting plate 22 are provided with threaded connection holes. The upper seat 2 can be detachably connected with the base 1 through the first connecting plates 12 and the second connecting plates 22. That is, when the front surface of the sheet is machined, the fasteners (such as bolts) are used to connect the upper seat 2 and the base 1 through the first connecting plates 12 and the second connecting plates 22 to fix the position of the upper seat 2 and ensure the stability of the upper seat 2, thereby ensuring the stability of the sheet during the machining process. The second support seats 23 can be arranged in a plurality of spaced-apart manner on one side wall of the upper seat frame 21, and the mounting positions of the second support seats 23 correspond to the mounting positions of the first support seats 13. The turnover connecting assembly 4 can be connected to the upper seat 2 through the second support seats 23 to realize the hinging of the upper seat 2 and the base 1.

[0029] Optionally, the upper seat 2 further comprises turnover lifting lugs 24 connected to the side walls of the upper seat frame 21.

[0030] Specifically, as shown in the drawings, Figure 3 The turnover lifting lugs 24 are symmetrically arranged on the two side walls of the upper seat frame 21 to provide lifting positions for the turnover of the upper seat 2. It should be noted that the positions of the turnover lifting lugs 24 correspond to the positions of the first support seats 13.

[0031] The turnover connecting assembly 4 comprises a first connecting seat 41, a turnover connecting shaft 42 and a nut 43. One end of the first connecting seat 41 is connected to the first supporting seat 13, and an axle hole is arranged on the other end of the first connecting seat 41. The turnover connecting shaft 42 penetrates through the turnover lug 24 and the axle hole, and the nut 43 is threadedly connected to the turnover connecting shaft 42.

[0032] Specifically, as shown in the figure, one end of the first connecting seat 41 matches the shape of the first supporting seat 13, and is used for being connected and fixed on the first supporting seat 13. An axle hole is arranged on the other end of the first connecting seat 41. When the upper seat 2 is installed on the base 1, the turnover lug 24 on the same side of the first supporting seat 13 is coaxial with the axle hole. The turnover connecting shaft 42 penetrates through the turnover lug 24 and the axle hole, and is fixed by the nut 43. When fixed, the nut abuts against the first connecting seat 41, thereby hingedly connecting the upper seat 2 and the base 1. Figure 4

[0033] Optionally, the pressing plate assembly 5 comprises a pressing plate 51, a first bolt 52, a first jackscrew seat 53, and a second connecting seat 54. The second connecting seat 54 is connected to the second supporting seat 23. The first jackscrew seat 53 is connected to one end of the second connecting seat 54 away from the second supporting seat 23. The pressing plate 51 is arranged parallel to the thin plate, and is connected to the second connecting seat 54. The first bolt 52 is threadedly connected in a direction perpendicular to the pressing plate 51, and penetrates through the first jackscrew seat 53. The end of the first bolt 52 is used for abutting against the pressing plate 51, so as to make the pressing plate 51 abut against the thin plate.

[0034] Specifically, as shown in the figure, one end of the second connecting seat 54 can be installed on the second supporting seat 23 by means of a bolt, thereby providing a connecting interface and support for the pressing plate 51 and the first jackscrew seat 53. The first jackscrew seat 53 can be installed on the other end of the second connecting seat 54 by means of a bolt, thereby providing a connecting basis for the first bolt 52. The pressing plate 51 is arranged parallel to the thin plate, and can be detachably connected to the second connecting seat 54 by means of a bolt, so that the pressing plate 51 is always above the thin plate, and the thin plate will not fall off or the like even during the turnover of the upper seat 2. The first bolt 52 is threadedly connected in a direction perpendicular to the pressing plate 51, and penetrates through the first jackscrew seat 53. The end of the first bolt 52 abuts against the pressing plate 51. The first bolt 52 provides an upper pressure for the pressing plate 51 by adjusting the extension length on the first jackscrew seat 53, thereby ensuring the stability of the thin plate processing. Figure 5

[0035] Optionally, the upper seat 2 is provided with a pressing plate moving-out hole 6, which is used for accommodating the pressing plate 51.

[0036] Specifically, after the upper seat 2 is turned over, the thin plate processing platform needs to be replaced, i.e. the thin plate is replaced to a replacement upper seat, as shown in the figure.​​Figure 6 As shown in the side view of the upper seat 2 after the turnover, the upper seat 2 is inverted, and the replacement upper seat is arranged below the upper seat 2 and placed in the normal direction. When replacing the upper seat of the thin plate, the pressing plate 51 is arranged between the replacement upper seat and the thin plate. If the pressing plate 51 and the thin plate are directly replaced from the position of the upper seat 2 to the support surface of the replacement upper seat, the pressing plate 51 cannot be removed, and the thin plate cannot be replaced. Therefore, as shown in the figure, the upper seat 2 is provided with a pressing plate removal hole 6 corresponding to the position of the pressing plate 51. When the pressing plate 51 is removed, the pressing plate 51 falls into the pressing plate removal hole 6, and the thin plate falls onto the support surface of the replacement upper seat, thereby completing the position replacement of the thin plate. At the same time, the pressing plate 51 falling into the pressing plate removal hole 6 can be taken out through the opening of the side wall. Figure 3

[0037] Optionally, the base frame 11 has a plurality of first segmented connecting seats 7 arranged at both ends of each base frame 11, and any two adjacent base frames 11 are connected through the first segmented connecting seat 7.

[0038] Specifically, as shown in the figure, the number of base frames 11 can be determined according to the length of the thin plate. For example, the length of the thin plate is 10 meters, and the length of the base frame 11 is 5 meters. Therefore, two base frames 11 are used to process the thin plate. In order to ensure the stability of the connection of the plurality of base frames 11, the first segmented connecting seat is arranged at both ends of the base frame 11, and the plurality of adjacent base frames 11 can be connected through the first segmented connecting seat 7. Figure 2

[0039] The upper seat frame 21 has a plurality of second segmented connecting seats 8 arranged at both ends of each upper seat frame 21, and any two adjacent upper seat frames 21 are connected through the second segmented connecting seat 8.

[0040] Specifically, as shown in the figure, the structure of the second segmented connecting seat 8 is the same as that of the first segmented connecting seat 7, and will not be described here. Figure 3

[0043] ​​​Specifically, the limiting assembly 9 is arranged to fix the four sides of the sheet, and the pressing plate assembly 5 is arranged to further fix the sheet, so as to ensure the stability of the sheet during the machining process. Figure 7 As shown in the figure, the second screw seat is arranged on the side wall of the upper seat 2, the second bolt 91 is threadedly connected along the direction parallel to the sheet and penetrates through the second screw seat 92, and the end of the second bolt 91 abuts against the four sides of the sheet, so as to fix the sheet.

[0044] Optionally, the jig platform for large-size sheet further comprises side edge pads 10 which are detachably connected to the peripheral end face of the upper seat 2 away from the base 1.

[0045] Specifically, as shown in the figure, the side edge pads 10 are movable assemblies which are fixed on the upper periphery of the upper seat 2 by bolts, and when the side edge of the sheet is machined, the side edge pads 10 can be removed to provide machining space. Figure 2
