Description

Technical Field

[0001] This utility model belongs to the field of shaft structure technology, specifically a high-stability rotating shaft structure for aircraft launch devices. Background Technology

[0002] During aerospace simulation experiments, a small launcher is scaled up proportionally. The launch process is simulated to complete data analysis, and the launch angle of the launcher is adjusted using axes.

[0003] According to the inspection institute, a rotating shaft structure for an aerospace launch device, authorized by CN214305121U, includes a base, a bearing fixed on the base, a support shaft with an interference fit inside the bearing, a first bushing fixed on the support shaft, a backstop plate fixed on the first bushing, a second bushing fixed on the support shaft, a support rod fixed on the base, a support sleeve slidably mounted on the support rod, a connecting plate fixed on the support sleeve, a backstop block fixed on the connecting plate, and a backstop groove provided on the backstop block. The backstop plate and the backstop groove are fitted together. This device enables the support shaft to rotate normally through the transmission of two sprockets. The backstop plate and the backstop groove on the backstop block provide a backstop protection effect, ensuring the safety of the structure. However, this device can only limit rotation in one direction. When other workpieces are heavy, the motor-based limit is still relatively unstable. Therefore, we propose a high-stability rotating shaft structure for aerospace launch devices. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 A high-stability rotating shaft structure for an air launch device includes a base 100. Two sets of support plates 110 are fixedly mounted on the upper side of the base 100. A rotating shaft 120 is rotatably connected to the opposite sides of the two sets of support plates 110. A first motor 130 is fixedly mounted on the upper side of the base 100. A rotating rod 140 is fixedly connected to the transmission end of the first motor 130. A reducer 150 is fixedly mounted on the left side of the first motor 130. The rotating rod 140 is connected to the input end of the reducer 150, and the output end of the reducer 150 is connected to the rotating shaft 120. A limit device 200 is provided on the left side of the first motor 130. During use, starting the first motor 130 drives the rotating rod 140 to rotate. The rotation of the rotating rod 140 drives the rotating shaft 120 through the reducer 150. The rotating shaft 120 rotates, thereby driving other workpieces or frames installed on the outside of the rotating shaft 120 to perform adjustment work. By setting the reducer 150, the precision of the adjustment of the rotating shaft 120 can be effectively improved. A bushing 121 is fixedly connected to the outside of the rotating shaft 120. The bushing 121 has an installation groove 122 on its outside. The installation groove 122 can be an annular groove or a spiral groove. By setting the bushing 121, it is easy to connect and install other workpieces or supports, thereby improving the stability of the device. A protective box 101 is fixedly connected to the upper side of the base 100. The first motor 130, rotating rod 140, reducer 150, and limit device 200 are all located inside the protective box 101. By setting the protective box 101, other workpieces are protected, thereby improving the safety of the device.

[0023] The limiting device 200 includes a housing 210 and a limiting wheel 220. The housing 210 is mounted on the upper side of the base 100. The limiting wheel 220 is fixedly mounted on the outer side of the rotating rod 140. A second motor 230 is fixedly mounted on the left side wall of the inner cavity of the housing 210. A screw 240 is fixedly connected to the transmission end of the second motor 230. A moving block 250 is screwed to the outer side of the screw 240. Multiple sets of insert rods 260 are fixedly connected to the right side of the moving block 250. The outer side of the limiting wheel 220 is evenly provided with locking holes that match the insert rods 260. During use, the second motor 230 is started, which drives the screw 240 to rotate. The rotation of the screw 240 drives the moving block 250 to move left and right. The left and right movement of the moving block 250 drives the insert rods 260 to move left and right, thereby causing the insert rods 260 to contact or disengage from the limiting wheel 220. When the insert rods 260 contact the limiting wheel 220, they can engage or disengage. The rod 140 and the rotating shaft 120 are limited to prevent the gas workpiece outside the rotating rod 140 from changing angle. By setting the limiting device 200, the limiting wheel 220, the rotating rod 140, and the rotating shaft 120 can be limited, thereby preventing other workpieces outside the rotating shaft 120 from changing angle, improving the stability and efficiency of the device, improving the practicality of the device, and reducing the stability and accuracy of the aircraft model launch experiment. The left side of the limiting wheel 220 is provided with a guide angle, and the right side of the insertion rod 260 is tapered. By setting the guide angle and the tapered right side of the insertion rod 260, the insertion rod 260 can easily enter the limiting wheel 220, improving the practicality of the device. Two sets of guide rods 251 are fixedly connected to the left and right side walls of the housing 210. The two sets of guide rods 251 pass through the front and rear sides of the moving block 250 respectively. By setting the guide rods 251, the moving block 250 is limited, improving the stability of the device.
