Technical Field

[0001] This utility model relates to the field of aviation manufacturing technology, and in particular to an automatic leveling device for a wing frame under-stack tooling. Background Technology

[0002] A trestle is a temporary auxiliary structure used in aircraft manufacturing and assembly. It is typically used to connect different work areas, provide passageways for personnel, materials and equipment, and serve as a support platform during operations. In aircraft manufacturing, trestle can greatly improve production efficiency.

[0003] To adapt to complex and ever-changing ground conditions, the trestle equipment needs to be leveled to keep the working surface of the trestle equipment horizontal, thereby ensuring safety during operation.

[0004] However, the aforementioned existing technologies mainly rely on manual adjustment of the trestle fixtures to ensure horizontal alignment, which is very time-consuming and labor-intensive, and the adjustment accuracy is low, making it difficult to meet operational requirements. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic leveling device for the trestle fixture under the wing frame, which aims to solve the technical problem that in the prior art, the trestle fixture is mainly adjusted by manual means, which is very time-consuming and labor-intensive, and the adjustment accuracy is low, making it difficult to meet the operational requirements.

[0006] To achieve the above objectives, this utility model employs an automatic leveling device for a wing frame under-stack fixture, comprising a base plate and a leveling mechanism. The leveling mechanism includes a level sensor, a controller, multiple sets of mounting components, and multiple sets of adjustment components. Each set of adjustment components includes a support column, a lifting rod, a lead screw, a motor, two sliders, a fixing component, and a support component. The level sensor and the controller are both disposed on the surface of the base plate, and the level sensor is electrically connected to the controller. The multiple sets of adjustment components are disposed on the lower surface of the base plate, and the support column is connected to the base plate via the fixing component. The lifting rod passes through the support column and is slidably connected to the support column. One end of each of the two sliders is fixedly connected to the lifting rod, and the other end of each slider passes through the support column and is slidably connected to the support column. The motor is disposed on the upper surface of the base plate and is electrically connected to the controller. One end of the lead screw is fixedly connected to the output end of the motor, and the other end of the lead screw passes through the lifting rod and is threadedly engaged with the lifting rod. The support member is disposed at the lower end of the lifting rod, and multiple sets of the mounting components are disposed on the upper surface of the base plate.

[0007] The fixing component includes a fixing plate and multiple bolts. The fixing plate is sleeved on the upper end of the support column, and the multiple bolts pass through the fixing plate and are threadedly connected to the base plate.

[0008] The support component includes a round rod, a ball sleeve, a ball, and a pad. One end of the round rod is fixedly connected to the lifting rod, and the other end of the round rod is fixedly connected to the ball sleeve. The ball is disposed inside the ball sleeve and is rotatably connected to the ball sleeve. The pad is fixedly connected to the ball.

[0009] Each set of installation components includes a column and a mounting plate. The column is fixedly connected to the base plate and located on the upper surface of the base plate. The mounting plate is fixedly connected to the column and located at the upper end of the column.

[0010] Each set of adjustment components further includes a connecting rod and a roller. The connecting rod is fixedly connected to the support column and is located on the outside of the support column. The roller is located at the lower end of the connecting rod.

[0011] This utility model discloses an automatic leveling device for a trestle fixture under an airframe. A lifting rod passes through a support column and is slidably connected to it. One end of a lead screw is fixedly connected to the output end of a motor, and the other end of the lead screw passes through the lifting rod and is threadedly engaged with it. In practical use, the trestle fixture is installed on a base plate using multiple sets of mounting components. A level sensor measures the tilt angle of the base plate and converts it into an electrical signal, which is sent to a controller. The controller then controls multiple motors, which drive the lead screw to rotate, causing the lifting rod to move the slider up or down. Simultaneously, the lifting rod moves the support component up or down until the base plate is level. This method effectively solves the problem in existing technologies where manual leveling of the trestle fixture is crucial, as it is time-consuming, labor-intensive, and has low accuracy, failing to meet operational requirements.

[0020] This utility model provides an automatic leveling device for a trestle fixture under an airframe, including a base plate 101 and a leveling mechanism. The leveling mechanism includes a level sensor 102, a controller 103, multiple sets of mounting components, and multiple sets of adjustment components. Each set of adjustment components includes a support column 104, a lifting rod 105, a lead screw 106, a motor 107, two sliders 108, a fixing component, and a support component. The fixing component includes a fixing plate 109 and multiple bolts 110. The support component includes a round rod 111, a ball sleeve 112, a ball 113, and a pad 114. Each set of mounting components includes a column 115 and a mounting plate 116. Each set of adjustment components also includes a connecting rod 117 and a roller 118. The aforementioned solution solves the problem in the prior art that the trestle fixture is mainly leveled manually, which is very time-consuming and labor-intensive, and the adjustment accuracy is low, making it difficult to meet the operational requirements.

[0021] In this specific embodiment, the level sensor 102 and the controller 103 are both disposed on the surface of the base plate 101, and the level sensor 102 is electrically connected to the controller 103. Multiple sets of adjustment components are disposed on the lower surface of the base plate 101. The support column 104 is connected to the base plate 101 via the fixing member. The lifting rod 105 passes through the support column 104 and is slidably connected to it. One end of each of the two sliders 108 is fixedly connected to the lifting rod 105, and the other ends of each slider 108 pass through the support column 104 and are slidably connected to it. The motor 107 is disposed on the upper surface of the base plate 101 and is electrically connected to the controller 103. One end of the lead screw 106 is fixedly connected to the output end of the motor 107. The lead screw 106 is fixedly connected to the lifting rod 105, with the other end threadedly engaging with it. The support member is located at the lower end of the lifting rod 105. Multiple sets of mounting components are mounted on the upper surface of the base plate 101. In actual use, the trestle fixture is mounted on the base plate 101 using multiple sets of mounting components. Then, the tilt angle of the base plate 101 is measured by the level sensor 102 and converted into an electrical signal, which is sent to the controller 103. The controller 103 then controls multiple motors 107, which drive the lead screw 106 to rotate, causing the lifting rod 105 to move the slider 108 up or down. Simultaneously, the lifting rod 105 moves the support member up or down until the base plate 101 is level.

[0022] The fixing plate 109 is sleeved on the upper end of the support column 104, and multiple bolts 110 pass through the fixing plate 109 and are threaded to the base plate 101. In actual use, the fixing plate 109 is fixed to the base plate 101 by multiple bolts 110, thereby fixing the support column 104.

[0023] Secondly, one end of the round rod 111 is fixedly connected to the lifting rod 105, and the other end of the round rod 111 is fixedly connected to the ball sleeve 112. The ball 113 is disposed inside the ball sleeve 112 and is rotatably connected to the ball sleeve 112. The pad 114 is fixedly connected to the ball 113. In actual use, the lifting rod 105 drives the round rod 111 to rise and fall. The round rod 111 drives the pad 114 to rise and fall through the ball sleeve 112 and the ball 113, thereby adjusting the level of the base plate 101. By rotating the ball 113 inside the ball sleeve 112, the pad 114 is always in contact with the ground.

[0024] Meanwhile, the column 115 is fixedly connected to the base plate 101 and located on the upper surface of the base plate 101. The mounting plate 116 is fixedly connected to the column 115 and located at the upper end of the column 115. In actual use, the bridge fixture is fixed on the mounting plate 116, and the mounting plate 116 is connected to the base plate 101 through the column 115.

[0025] In addition, the connecting rod 117 is fixedly connected to the support column 104 and is located on the outside of the support column 104. The roller 118 is disposed at the lower end of the connecting rod 117. In actual use, the roller 118 is connected to the support column 104 through the connecting rod 117. When the lifting rod 105 moves completely into the interior of the support column 104, the roller 118 will contact the ground, thereby facilitating the movement of the device.

[0026] In the automatic leveling device of the wing frame under-stack fixture of this embodiment, the staircase fixture is installed on the mounting plate 116. Then, the tilt angle of the base plate 101 is measured by the level sensor 102 and converted into an electrical signal and sent to the controller 103. The controller 103 then controls multiple motors 107, which drive the lead screw 106 to rotate, causing the lifting rod 105 to move the slider 108 up or down. 105 drives the round rod 111 to move up or down. The round rod 111 drives the pad 114 to move up or down through the ball sleeve 112 and the ball 113, thereby adjusting the level of the base plate 101. The ball 113 rotates within the ball sleeve 112, so that the pad 114 is always in contact with the ground. This method can effectively solve the problem that in the prior art, the leveling of the trestle fixture is mainly adjusted manually, which is very time-consuming and labor-intensive, and the adjustment accuracy is low, making it difficult to meet the needs of operation.

[0027] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
