Description

Technical Field

[0001] This utility model relates to the technical field of box support mechanisms, specifically to a support mechanism for the opening of large box-type workpieces. Background Technology

[0002] In the field of modern mechanical manufacturing, large box-shaped workpieces are widely used in key industries such as aerospace, energy equipment, and heavy machinery. These workpieces are typically characterized by large size, complex structure, and spacious internal space. Their open structure design facilitates the installation and assembly of internal components, making them an important structural form for meeting the functional requirements of equipment.

[0003] During workpiece machining, especially in high-precision cutting processes such as milling and boring, external loads such as cutting forces and clamping forces act on the openings, easily causing local elastic or plastic deformation. Because large box-shaped workpieces require extremely high machining accuracy, even minor deformations can lead to dimensional deviations in various parts of the workpiece, such as offset hole diameters, increased flatness errors, and decreased fit accuracy of box assembly surfaces. This severely affects the functionality and assembly accuracy of the workpiece, rendering it unusable and scrap. Utility Model Content

[0004] Technical problems to be solved

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a support mechanism for the opening of large box-shaped workpieces, which can effectively solve the problems in the existing technology.

[0008] This utility model provides a support mechanism for the opening of a large box-shaped workpiece, including pull plates fixed on both sides of the outer opening of the large box-shaped workpiece. The pull plates are connected and fixed to each other by a main support plate. The main support plate includes outer plates on both sides, an inner plate disposed at the top between the outer plates, and a bottom plate fixed to the bottom of the outer plates. An arc-shaped groove is formed on the inner side of the pull plate, and an arc-shaped groove is formed on the outer side of the inner plate. An insert is inserted between the arc-shaped groove and the arc-shaped groove. The pull plate and the bottom plate are fixedly connected by a side plate, and an arc-shaped groove is formed at the bottom end of the side plate. The bottom plate is inserted into the arc-shaped groove.

[0009] Furthermore, the bottom end of the pull plate is fixedly connected to the large box workpiece through the connecting plate, and threaded holes are provided on the pull plate, the connecting plate and the large box workpiece, and the three sets of structures are connected and fixed by bolts and nuts.

[0010] Furthermore, both sides of the outer plates are provided with arc-shaped slot structures, and the two sides of the outer plates are inserted into the inner side of the pull plate, and the cross-section of the side plates is a triangular structure.

[0011] Furthermore, both the connecting plate and the pull plate have multiple sets of slotted hole structures.

[0012] Furthermore, the top ends of the side plates on both sides are fixedly connected to the bottom ends of the pull plate.

[0013] Furthermore, both of the pull plates on both sides are trapezoidal structures with a larger outer side and a smaller inner side.

[0014] Beneficial effects

[0015] The technical solution provided by this utility model has the following advantages compared with the known public technology:

[0016] This utility model utilizes a combination structure of pull plates, main support plates, and bolts. The pull plates on both sides are fixedly connected to the openings of the large box-shaped workpiece via connecting plates. The pull plates on both sides are then connected and fixed together by the main support plate. During assembly, the main support plate structure can be engaged with the arc-shaped groove on the pull plate through its inner plate and insert block. The other end of the insert block is also engaged with the arc-shaped groove on the inner plate. The side plate structure fixed to the bottom of the pull plate provides support. The outer plates on both sides are laterally engaged with the side walls of the pull plate through arc-shaped grooves. The bottom plate is then engaged with the grooves on the side plates to complete the fixing. This utility model's support and fixing structure prevents workpiece deformation and meets the requirements for processing, hoisting, and transportation. Attached Figure Description
