Description

Technical Field

[0001] This utility model relates to the field of aircraft manufacturing and processing equipment technology, and more specifically to a support frame for aircraft partition inspection. Background Technology

[0002] Existing aircraft bulkheads come in various sizes and have non-standard and complex mounting holes. After processing, it is necessary to check whether the hole processing is in place.

[0003] Traditional test brackets are typically fixed by full welding or directly machined to form a test bracket. These brackets are usually designed one-to-one, meaning they can only be used for testing one type of aircraft bulkhead. Their applicability is limited, their flexibility is poor, they are difficult to modify, and they need to be redesigned and manufactured to fit new bulkheads, resulting in high costs and long lead times. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a support frame for aircraft bulkhead inspection. All its components are detachable, allowing them to be disassembled and reused. Furthermore, it uses wooden upper positioning connecting blocks, side positioning connecting blocks, and front transverse inspection blocks as transitional parts for installing aircraft bulkheads. Its installation and disassembly are convenient, and its manufacturing cost is low.

[0005] The solution of this utility model to the aforementioned technical problem is:

[0006] A support frame for testing aircraft partitions includes a bottom frame. Side vertical columns are fixed to the top surfaces of the left and right sides of the rear part of the bottom frame. An upper transverse beam is fixed between the tops of the two side vertical columns. An oblique support beam extending forward and downward is fixed to the front wall surface of the middle part of the side vertical columns. The bottom surface of the front end of the oblique support beam is fixed to the top surface of the bottom frame.

[0007] A middle support beam is fixed between the middle of the two side vertical columns. Multiple front oblique guide rods are installed at the front of the middle support beam. The front oblique guide rods extend obliquely forward and downward.

[0008] The bottom surface of the upper transverse beam is fixed with upper positioning connecting blocks on the left and right sides, and the side walls of the two upper positioning connecting blocks that are far apart are fixed on the upper inner side wall of the corresponding side vertical column.

[0009] A positioning hole support frame is installed on the bottom surface of the upper transverse beam between the two upper positioning connecting blocks.

[0010] The two upper positioning connecting blocks are made of wood. The bottom surface of the middle part of the two upper positioning connecting blocks is formed with an upwardly extending upper arc-shaped positioning groove. The bottom surface of the two upper positioning connecting blocks on the side away from each other is formed with a downwardly extending side extension. The outer side wall of the side extension is fixed to the inner side wall of the corresponding side vertical column. The inner side wall of the two side extensions is an arc-shaped wall surface that matches the aircraft partition to be tested.

[0011] A lower connecting beam is fixed at the lower part between the two side vertical columns. The lower connecting beam is located directly below the middle support beam. Multiple upper connecting seats are fixed on the front wall of the middle support beam, and multiple lower connecting seats are fixed on the front wall of the lower connecting beam. The fixed seat on the bottom surface of the upper part of the front inclined guide rod is movably connected to the corresponding upper connecting seat.

[0012] The bottom ends of all the forward oblique guide rods are fixed to the same horizontally extending connecting beam by angle brackets. Multiple rear connecting beams extending obliquely to the rear are fixedly connected to the rear wall of the horizontal connecting beam by angle brackets. The top rear end of all the rear connecting beams is fixed with a fixing seat, and the fixing seat is movably connected to the corresponding lower connecting seat.

[0013] Side positioning connecting blocks are fixed on the opposite walls of the two inclined support beams. The side positioning connecting blocks are wooden strip blocks. The opposite walls of the two side positioning connecting blocks are arc-shaped walls. The distance between the lower parts of the two arc-shaped walls is smaller than the distance between the upper parts.

[0014] The bottom frame consists of two bottom transverse beams extending left and right corresponding to each other and two bottom side beams extending front and back. The left and right ends of the two bottom transverse beams are fixed to the inner side walls of the two bottom side beams by corner brackets to form a bottom rectangular frame component.

[0015] The bottom of the two side vertical columns is fixed to the rear top surface of the two bottom side beams by angle brackets, and the top surfaces of the left and right ends of the rear bottom horizontal beam are fixedly connected to the bottom of the two side vertical columns by angle brackets.

[0016] The upper part of the inclined support beam is fixedly connected to the front wall of the corresponding side vertical column by angle brackets;

[0017] The front portion between the top of the two side vertical columns and the end of the upper transverse beam is fixed by a front base plate, and the rear portion between the top of the two side vertical columns and the end of the upper transverse beam is fixed by a rear base plate.

[0018] The left and right sides of the top surfaces of the intermediate support beam and the lower connecting beam are fixed to the inner walls of the corresponding side vertical columns by angle brackets.

[0019] Two front transverse detection blocks are fixed to the top surface of the bottom transverse beam at the front of the bottom frame. The front transverse detection blocks are wooden blocks with sloping top surfaces. The top surfaces of the two front transverse detection blocks are close to the bottom end and far from the top end.

[0020] The outstanding effect of this utility model is:

[0021] 1. It is highly adaptable: all its components are detachable and reusable. At the same time, it uses readily replaceable and easily processed wooden parts to make upper positioning connecting blocks, side positioning connecting blocks and front transverse detection blocks as transition parts. It is easy to install and disassemble, and has low manufacturing cost. It can replace the transition parts with corresponding shapes as needed, so as to meet the inspection needs of various types of aircraft bulkheads, greatly improving the versatility and economy of the support frame.

[0022] 2. The upper positioning connecting block, side positioning connecting block and front transverse detection block are made of wood and can be processed with high precision to ensure accurate matching with the holes of the aircraft partition to be tested; its soft material properties can effectively protect the aircraft partition from damage during installation and testing.

[0023] 3. Short development cycle and low cost: To adapt to the new partition, only the wooden blocks need to be remade, without modifying or remaking the main components of the support frame, which greatly shortens the tooling preparation time and reduces testing costs.

[0024] 4. Stable structure and easy maintenance: The support frame uses metal components, providing a stable support foundation, and the overall structure is easy to disassemble and reassemble. The upper positioning connecting block, side positioning connecting block, and front transverse detection block are made of wood, which is easy to replace after damage and has extremely low maintenance costs.

[0025] 5. It has good shock absorption effect: the upper positioning connecting block, the side positioning connecting block and the front transverse detection block are made of wood. The natural damping characteristics of wood help absorb the vibration generated during the test, providing a more stable and accurate data acquisition environment for the test.
