Description

Technical Field

[0001] This utility model relates to the field of aircraft pallet processing technology, specifically to a plane drilling tool for aircraft pallets. Background Technology

[0002] Aircraft pallets are mainly used in air cargo transportation and aircraft maintenance. During cargo transportation, pallets provide a stable support platform for the cargo, preventing it from directly contacting the ground or cabin floor and protecting it from damage caused by moisture or collisions. Simultaneously, during transport, pallets can secure the cargo within a certain range, reducing movement and shaking within the cabin and further protecting the cargo's integrity. During aircraft maintenance, pallets can be used to carry various maintenance equipment, tools, and spare parts, facilitating the transport of necessary items to the aircraft maintenance site and enabling the orderly placement and management of these items, thus improving the efficiency of maintenance work.

[0003] In the processing of aircraft pallets, holes need to be drilled to facilitate the installation of fasteners such as screws and nails, ensuring a stable connection between the pallet and transport vehicles, racks, or other equipment, and guaranteeing load-bearing capacity and service life. However, current drilling devices are prone to drill bit deviation during operation, resulting in tilted holes, which makes subsequent connection inconvenient and reduces production quality. To address this issue, I provide a flat drilling fixture for aircraft pallets. Utility Model Content

[0004] The purpose of this utility model is to provide a drilling tool for aircraft pallet planes to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A tooling for drilling planes on aircraft pallets includes a processing table, a base fixedly installed on the bottom of the processing table, support brackets fixedly connected to both sides of the base, a horizontal plate welded to the top of the support brackets, and a drill bit provided at the bottom of the horizontal plate.

[0007] Limiting units are provided on both sides of the drill bit, and positioning units are provided on both sides and the bottom of the processing table.

[0008] The limiting unit includes a fixed sleeve plate that is fixedly sleeved above the drill bit and located on the outer surface of the sleeve. Limiting rods are movably inserted into both sides of the fixed sleeve plate. The drill bit and the sleeve are movably connected. When the drill bit rotates and moves downward, the sleeve remains stationary and moves downward.

[0009] A further improvement of this utility model is that: the top end of the limiting rod penetrates through the horizontal plate and extends above the horizontal plate; a pressing plate is fixedly connected to the bottom end of the limiting rod; and a rubber pad is fixedly connected to the outer surface of the bottom end of the pressing plate. The rubber pad can provide protection when the pressing plate contacts the aircraft clamping plate, preventing scratches from being caused by the pressing.

[0010] A further improvement of this utility model is that: an elastic wire is movably sleeved on the outer surface of the limiting rod below the fixed sleeve plate, one end of the elastic wire is fixedly installed on the bottom end of the fixed sleeve plate, and the other end of the elastic wire is fixedly installed on the top of the extrusion plate.

[0011] A further improvement of the present invention is that the positioning unit includes a rotating shaft fixedly installed on both sides of the processing table, a hydraulic cylinder is fixedly installed on the top of the base, and a piston rod is provided at the extension end of the hydraulic cylinder.

[0012] A further improvement of this utility model is that a top plate is fixedly connected to the other end of the piston rod, and a connecting cross plate is fixedly installed on both ends of the top plate.

[0013] A further improvement of this utility model is that: push-pull plates are rotatably connected to both ends of the connecting horizontal plate, and an adjustment plate is rotatably connected to the other end of the push-pull plate, with the other end of the adjustment plate rotatably installed inside the rotating shaft.

[0014] A further improvement of this utility model is that a pressure plate is fixedly installed at the top of the other end of the adjustment plate, and a friction pad is fixedly installed on the inner side of the pressure plate. The pressure plate squeezes the aircraft clamping plate, which can promote the stability of the clamping plate during drilling and further improve the drilling accuracy.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides a drilling fixture for aircraft pallet planes. By setting up a pressing plate, the pressing plate first abuts against the aircraft pallet when the drill bit moves down. As the drill bit continues to move down, the fixing sleeve slides down along with it and presses the elastic wire on the outer surface of the limiting rod. The limiting rod limits the drilling of the drill bit, so that it can drill vertically and prevent the hole from tilting, thereby improving the drilling quality and further improving production efficiency.

[0017] 2. This utility model provides a drilling fixture for aircraft pallet planes. By setting up a hydraulic cylinder, the extended end of the cylinder pushes the piston rod to move upward. The other end of the piston rod pushes the top plate and the connecting horizontal plate to move upward. The two ends of the connecting horizontal plate push the adjusting plate to cause the pressure plate to press against the top of the side of the aircraft pallet. Multiple pressure plates can promote the positioning of the aircraft pallet. With the help of friction pads, scratches can be prevented from being caused by extrusion. At the same time, the rubber material can enhance the friction of extrusion and further promote stability. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] like Figures 1-5As shown, this utility model provides a drilling fixture for aircraft pallet planes, including a processing table 1. A base 2 is fixedly installed on the bottom end of the processing table 1. Support brackets 3 are fixedly connected to both sides of the base 2. A horizontal plate 31 is welded to the top of the support brackets 3. A drill bit 4 is provided at the bottom end of the horizontal plate 31. Limiting units are provided on both sides of the drill bit 4. Positioning units are provided on both sides and the bottom of the processing table 1. The limiting unit includes a fixed sleeve plate 41 fixedly sleeved above the drill bit 4 on the outer surface of the sleeve. Limiting rods 42 are movably inserted into both sides of plate 41. The top of the limiting rods 42 penetrates through the horizontal plate 31 and extends above the horizontal plate 31. A pressing plate 43 is fixedly connected to the bottom of the limiting rods 42. A rubber pad 44 is fixedly connected to the outer surface of the bottom end of the pressing plate 43. An elastic wire 45 is movably sleeved on the outer surface of the limiting rods 42 below the fixed sleeve plate 41. One end of the elastic wire 45 is fixedly installed on the bottom end of the fixed sleeve plate 41, and the other end of the elastic wire 45 is fixedly installed on the top of the pressing plate 43.

[0027] Furthermore, the piston rod 22 is pushed upward by the extension end of the hydraulic cylinder 21, and the other end of the piston rod 22 pushes the top plate 23 and the connecting horizontal plate 24 to move upward as well. The two ends of the connecting horizontal plate 24 push the adjusting plate 26 to cause the pressure plate 27 to press against the top of the side of the aircraft clamping plate. Multiple pressure plates 27 can promote the positioning of the aircraft clamping plate. Together with the friction pad 28, it can prevent scratches from being caused by the extrusion. At the same time, its rubber material can enhance the friction of the extrusion and further promote stability.

[0028] Example 2

[0029] like Figures 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the positioning unit includes a rotating shaft 11 fixedly installed on both sides of the processing table 1, a hydraulic cylinder 21 fixedly installed on the top of the base 2, a piston rod 22 provided at the extended end of the hydraulic cylinder 21, a top plate 23 fixedly connected to the other end of the piston rod 22, a connecting horizontal plate 24 fixedly installed on both ends of the top plate 23, a push-pull plate 25 rotatably connected to both ends of the connecting horizontal plate 24, an adjusting plate 26 rotatably connected to the other end of the push-pull plate 25, the other end of the adjusting plate 26 rotatably installed inside the rotating shaft 11, a pressure plate 27 fixedly installed on the top of the other end of the adjusting plate 26, and a friction pad 28 fixedly installed on the inner side of the pressure plate 27.

[0030] Furthermore, the drill bit 4 rotates and moves downward under the drive of the hydraulic assembly and the motor assembly (not shown in the figure) to drill a hole in the aircraft clamping plate. The first thing the drill bit 4 contacts when it moves downward is the pressing plate 43. The pressing plate 43 abuts against the clamping plate. As the drill bit 4 continues to move downward, the fixing sleeve 41 moves downward and slides on the outer surface of the limiting rod 42 and presses the elastic wire 45. The limiting rod 42 limits the drilling of the drill bit 4, so that it can drill vertically and prevent the hole from tilting. When the drill bit 4 returns to its original position, the pressing plate 43 also returns to its original position under the elastic potential energy of the elastic wire 45.

[0031] The working principle of the aircraft pallet flat drilling tool will be explained in detail below.

[0032] like Figures 1-5 As shown, during use, the aircraft clamp to be drilled is placed on top of the processing table 1. Then, the extension end of the hydraulic cylinder 21 pushes the piston rod 22 upwards. The other end of the piston rod 22 pushes the top plate 23 and the connecting horizontal plate 24 upwards. The two ends of the connecting horizontal plate 24 push the adjusting plate 26, causing the pressure plate 27 to press against the top edge of the aircraft clamp. Multiple pressure plates 27 facilitate the positioning of the aircraft clamp. Combined with the friction pad 28, it prevents scratches from the pressure. Simultaneously, its rubber material enhances the friction of the pressure, further promoting stability. Driven by the hydraulic and motor components (not shown in the figure), the drill bit 4 rotates and moves downward to drill a hole in the aircraft clamping plate. The first part of the drill bit 4 that comes into contact with the clamping plate is the extrusion plate 43. The extrusion plate 43 presses against the clamping plate. As the drill bit 4 continues to move downward, the fixed sleeve 41 moves downward and slides on the outer surface of the limiting rod 42, extruding the elastic wire 45. The limiting rod 42 limits the drilling of the drill bit 4, allowing it to drill vertically and preventing the hole from tilting. When the drill bit 4 returns to its original position, the extrusion plate 43 also returns to its original position under the elastic potential energy of the elastic wire 45.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
