Description

Technical Field

[0001] This utility model relates to the technical field of clamping worktables for repairing the surface of aircraft generator housings, and specifically to a clamping worktable for repairing the surface of aircraft generator housings. Background Technology

[0002] Aircraft generators are essential components for ensuring the normal operation of aircraft. However, if an aircraft generator is damaged, the repair or maintenance cycle is relatively long. Traditional maintenance benches have a fixed area and the clamping of the generator is not secure, which affects the maintenance of the generator.

[0003] Existing aircraft generator maintenance platforms lack sufficient clamping strength and have limited functionality. For example, the self-propelled pure electric aircraft maintenance lifting platform disclosed in publication number CN216997557U includes: a pure electric special-purpose vehicle chassis, a platform lifting scissor lift, a platform, a platform lifting cylinder, a hydraulic oil tank, a power take-off, and a hydraulic pump. Compared to existing technologies, this self-propelled pure electric aircraft maintenance platform uses a pure electric special-purpose vehicle chassis instead of a diesel engine chassis, allowing for a more rational layout and enabling the platform to handle larger lifting heights and weights. It uses a DC / AC inverter to replace the diesel generator set for powering the platform's lighting and power tools. An electric air compressor replaces the hydraulically driven air compressor to provide air to the platform. This achieves zero emissions during operation and significantly reduces environmental pollution. However, the clamping of the generator in this design is not entirely secure, and it is still prone to shaking and loosening.

[0004] Therefore, it is necessary to invent a clamping worktable for repairing the surface of an aircraft generator housing to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a clamping workbench for repairing the surface of an aircraft generator housing, in order to solve the problems in the technology of not being able to fully and securely clamp the aircraft generator during maintenance, and the inability to promptly remove dust and odors from the air.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A clamping workbench for repairing the surface of an aircraft generator housing includes a workbench body, a spraying device, and a spray nozzle. The spraying device and spray nozzle are driven by a linear guide rail and a cylinder on the workbench body. An operating platform is located directly below the spray nozzle, and multiple clamping mechanisms are arranged around the operating platform. An air pump is installed at the bottom of the workbench body, and the air pump is connected to a filter mechanism through a pipe. Several gas pipes are arranged inside the filter mechanism. The top ends of the gas pipes are distributed on both sides of the operating platform and are flush with the bottom surface of the operating platform. A baffle is slidably installed on the upper surface of the operating platform. The baffle opens and blocks the top ends of the gas pipes by means of lateral sliding.

[0008] The main body of the workbench is provided with multiple sliding grooves, and springs and sliders are respectively installed in the sliding grooves. The springs and sliders are located on both sides of the baffle.

[0009] The baffle is an arc-shaped plate, the size of which matches the through hole on the main body of the workbench, and the shape of the through hole matches the shape of the top of the gas pipe.

[0010] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0011] 1. This utility model uses multiple clamping mechanisms around the operating table to clamp the side of the generator that needs to be repaired, and then uses the downward movement of the spraying device to synchronously drive the spray nozzle to perform the repair operation.

[0012] 2. This utility model uses a threaded rod to drive the rotation of a gear, causing the racks on opposite sides to move relative to each other, opening the baffles on both sides, opening the top of the gas pipe, and starting the suction pump to collect the odor during paint touch-up and the dust in the air during maintenance.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] This utility model provides, for example Figures 1-3 The diagram shows a clamping workbench for repairing the surface of an aircraft generator housing. It includes a main workbench 1, a spraying device 2, and a spray nozzle 3. The spraying device 2 and spray nozzle 3 are driven by linear guides and cylinders on the main workbench 1. An operating platform 4 is located directly below the spray nozzle 3. Multiple clamping mechanisms 5 are arranged around the operating platform 4. An air pump 6 is installed at the bottom of the main workbench 1. The air pump 6 is connected to a filter mechanism 7 via pipes. Several gas pipes 8 are installed within the filter mechanism 7. The top ends of the gas pipes 8 are distributed on both sides of the operating platform 4 and are flush with the bottom surface of the operating platform 4. A baffle 103 is slidably installed on the upper surface of the operating platform 4. The baffle 103 opens and closes the top ends of the gas pipes 8 by sliding laterally. When the generator to be repaired is placed on the operating platform 4, it is clamped by the multiple clamping mechanisms 5, securing both the top and sides, making repair and operation more secure.

[0022] The workbench body 1 has multiple sliding grooves 101, each containing a spring 102 and a slider 104, which are positioned on either side of a baffle 103. Under the action of the spring 102, the baffle 103 can smoothly return to its original position when opened. Opening the baffle 103 opens the top of the gas pipe 8, allowing the air pump 6 to begin pumping air to absorb dust and odors during maintenance or paint touch-up.

[0023] The baffle 103 is an arc-shaped plate. The size of the baffle 103 matches the through hole opened on the workbench body 1, and the shape of the through hole matches the shape of the top of the gas pipe 8.

[0024] The lower end face of the operating table 4 is connected to a cylinder seat 401, and a push cylinder 402 is connected to each side of the cylinder seat 401.

[0025] Each of the push cylinders 402 has an output shaft connected to a threaded rod 403. A gear 404 is threaded onto the threaded rod 403, and the gear 404 meshes with a toothed plate 405. The toothed plate 405 is connected to a slider 104. The gear 404 is connected to the lower end face of the operating table 4 via bearings and a bracket. The gear 404 is restricted to rotation only and cannot move along its axis. When the push cylinders 402 on both sides drive the threaded rods 403 to move, they drive the two gears 404 to rotate, causing the two toothed plates 405 to move relative to each other, pushing open the baffles 103 on both sides, and opening the top of the gas pipe 8 to begin the suction operation. This utility model uses two independent push cylinders 402 as power sources, and at the same time, it uses a gear and rack mechanism to reverse the transmission power, avoiding spatial interference between the transmission structure and the gas pipe 8. This ensures that the gas pipe 8 has effective installation space and also enables the driving of the baffles 103.

[0026] The length of the slider 104 is one-quarter of the length of the groove 101.

[0027] Multiple slides 101 are respectively opened on both sides of the operating table 4, in pairs. Each pair of slides 101 is provided with a spring 102 and a slider 104, and the slider 104 slides in the slide 101.

[0028] The clamping mechanism 5 is driven by a cylinder, and the end of the cylinder push shaft is arc-shaped. A rubber pad is provided on the surface of the arc shape. The use of a rubber pad can prevent damage to the product surface.

[0029] Working principle of this utility model:

[0030] Refer to the instruction manual appendix Figures 1-3 First, the generator that needs to be repaired is placed on the operating table 4, and the cylinder is started to make multiple clamping mechanisms 5 start to operate synchronously, so that the side of the generator is clamped synchronously.

[0031] Then, the linear guide rail and cylinder are used to drive the spraying device 2 and the nozzle 3 to move downwards, and to start operations such as touch-up painting or cleaning rust from the surface.

[0032] Refer to the instruction manual appendix Figures 3-5 At the same time, the push cylinder 402 drives the corresponding threaded rod 403 to move, which drives the gear 404 to rotate. The gear plate 405 is moved in conjunction, pushing open the baffles 103 on both sides. This opens the gas pipe 8 that was originally blocked, allowing the collection of waste materials from generator maintenance or painting operations on the workbench body 1 and the operating table 4, or the collection of odors from painting operations.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
