Description

Technical Field

[0001] This utility model belongs to the field of aircraft parts processing technology, specifically relating to an auxiliary device for drilling holes on the side of aircraft parts. Background Technology

[0002] In the field of aircraft manufacturing, the connection and assembly of parts often require side drilling, such as machining mounting holes for various structural parts and connectors to meet the fastening and connection requirements between components. This is crucial to the overall structural strength, assembly accuracy, and even flight safety of the aircraft. Efficient and precise side drilling is one of the key links to ensure the production quality and assembly efficiency of aircraft parts.

[0003] In side drilling operations for aircraft parts, the positioning accuracy of the drilling device directly affects the drilling quality. In existing technologies, most drilling positioning components can only achieve position adjustment in one direction. If adjustment is only possible in one direction, it is often difficult to simultaneously ensure the horizontal and vertical positional adaptation when facing drilling positions that require precise alignment. This can easily lead to drilling position deviations, which in turn affect the assembly fit of the parts, increase the difficulty of subsequent assembly processes, and may even cause parts to be scrapped due to inaccurate positioning. This reduces production efficiency and increases production costs. Positioning components that can adjust their position in both vertical and horizontal directions can effectively solve this problem and provide strong support for precise drilling. Therefore, there is a need for an auxiliary device for side drilling of aircraft parts. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary device for drilling holes on the side of aircraft parts that has a simple structure and reasonable design in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] An auxiliary device for drilling holes on the side of an aircraft component includes a worktable with a component groove on its surface. A component to be processed is disposed on the upper side of the worktable and fits tightly against the component groove. A triangular stop is fixed to the upper side of the worktable on the outer side of the component to be processed. Multiple clamping assemblies are disposed at the contact point between the component to be processed and the triangular stop. A positioning assembly is disposed on the side of the worktable away from the triangular stop, and a drilling assembly is disposed on the positioning assembly.

[0007] As a further optimization of this utility model, each set of clamping components includes two clamping blocks disposed inside the triangular stop and inside the part to be processed. Two threaded rods are rotatably sleeved on the surfaces of the two clamping blocks, and each threaded rod has a nut threaded through both ends after passing through the clamping block.

[0008] As a further optimization of this utility model, the positioning component includes a component housing disposed on the side of the part to be processed. A bottom slide rail is disposed on the inner bottom of the component housing, and a top slide rail is disposed on the top of the component housing. A translation bracket is disposed between the top slide rail and the bottom slide rail. A roller that slides on the inner side of the top slide rail is disposed on the top of the translation bracket, and a roller that slides on the inner side of the bottom slide rail is disposed on the bottom of the translation bracket. A translation motor is disposed on the surface of the translation bracket, and a first gear is fixedly inserted through the output shaft end of the translation motor. A first rack that meshes with the first gear is disposed at the front end of the bottom slide rail.

[0009] As a further optimization of this utility model, the surface of the translation bracket has two vertical sliding grooves, the back of the translation bracket is slidably provided with a connecting plate, each vertical sliding groove has a movable rod fixed to the connecting plate sliding inside, the front end of the translation bracket is slidably provided with a lifting bracket, the surface of the lifting bracket has a horizontal sliding groove, and the movable rod slides inside the horizontal sliding groove after passing through the translation bracket.

[0010] As a further optimization of this utility model, a second rack is fixed to the inner side of the component housing at one end of the first rack, a lifting motor is provided at one end of the lifting bracket, a second gear meshing with the second rack is fixedly passed through the output shaft end of the lifting motor, a fixing rod is fixed to the surface of the lifting bracket away from the lifting motor, an auxiliary gear is rotatably passed through the surface of the fixing rod, a limit block is fixed to the end of the fixing rod away from the lifting bracket, and a third rack meshing with the auxiliary gear is fixed to the inner left side surface of the component housing.

[0011] As a further optimization of this utility model, the drilling assembly includes an assembly frame fixed to the front end of a movable rod that passes through the vertical support. A cylinder is provided at the bottom inner side of the assembly frame, a push plate is fixed at the output end of the cylinder, a drilling motor is provided on the surface of the push plate, and a drill bit is threadedly connected to the output shaft end of the drilling motor.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. In this utility model, the positioning component uses a translation motor to drive a gear and rack to mesh, thereby moving the translation bracket horizontally. Simultaneously, a lifting motor drives a gear and rack to adjust the lifting bracket and moving rod vertically, thus synchronously adjusting the horizontal and vertical positions of the drilling component. This component can achieve simultaneous adjustment in both vertical and horizontal directions, quickly and accurately aligning the holes to be processed without step-by-step operations. This effectively avoids positioning deviations that are prone to occur with single-direction adjustments, significantly improving the flexibility and accuracy of drilling positioning, ensuring the processing quality of side drilling of aircraft parts, simplifying the operation process, improving overall processing efficiency, and reducing component wear caused by inaccurate positioning.

[0014] 2. In this utility model, the part to be processed is initially positioned by fitting its bottom into the part groove of the worktable, and then positioned by fitting its side into the triangular stop. The clamping blocks, threaded rods and nuts of the clamping assembly interact to generate clamping force, thereby achieving a stable fixation of the part to be processed. This fixing method, through multiple positioning and clamping combinations, greatly improves the stability and reliability of the fixation of the part to be processed, effectively avoids displacement or shaking of the part during the drilling process, ensures the accuracy of the drilling position, and at the same time, the fixing operation is simple and quick, adapts to the structural characteristics of the part to be processed, reduces the difficulty of operation, and provides a solid guarantee for subsequent accurate drilling.

[0025] like Figure 4 , Figure 5 As shown, a drilling component 7 is provided on the positioning component 6. The drilling component 7 is used to drill holes in the workpiece 1 to be processed. The drilling component 7 includes a component frame 701 fixed to the front end of the moving rod 618. The component frame 701 is used to accommodate other components. A cylinder 702 is provided on the inner bottom of the component frame 701. A push plate 703 is fixed to the output end of the cylinder 702. A drilling motor 704 is provided on the surface of the push plate 703. The drilling motor model in this utility model is A06B-0226-B100. A drill bit 705 is threaded onto the output shaft end of the machine 704. A cylinder 702 is used to push a push plate 703 to extend the drilling motor 704 so that the drill bit 705 contacts the workpiece 1 to be processed. The push plate 703 is used to fix the drilling motor 704 and moves with the push of the cylinder 702. The drilling motor 704 is used to drive the drill bit 705 to rotate to drill holes in the workpiece 1. The drill bit 705 is used to contact the workpiece 1 to drill holes. At the same time, the drill bit can be disassembled from the output shaft end of the drilling motor to meet the drilling requirements of different hole diameters.

[0026] It should be noted that, in the use of this auxiliary device for side drilling of aircraft parts, the operator first places the part to be processed 1 on the workbench 2 by hoisting it. The part groove 3 on the workbench 2 is tightly fitted with the bottom of the part to be processed 1 to complete the simple limiting. The side of the part to be processed 1 with the triangular groove is fitted with the triangular stop 4. Then, several clamping components 5 are placed at the fitting point between the triangular stop 4 and the part to be processed 1. First, the clamping blocks 501 are placed on the inner side of the triangular stop 4 and the inner side of the part to be processed 1 respectively. Then, the nut 503 is threaded onto the threaded rod 502, so that the nut 503 squeezes the clamping block 501, thereby clamping the part to be processed 1 and the triangular stop 4, so that the part to be processed 1 and the triangular stop 4 are further fitted together.

[0027] After clamping is completed, the operator controls the translation motor 607 and the lifting motor 611 to make the gear fixed at the output end of the motor slide on the surface of the meshing rack, thereby adjusting the moving rod 618 that passes through the translation bracket 604 and the vertical bracket, as well as the drilling assembly 7 fixed at the front end of the moving rod 618. When the drill bit 705 of the drilling assembly 7 is aligned with the drilling position of the workpiece 1 to be processed, the positioning of the drilling assembly 7 is completed. Then, the cylinder 702 inside the component frame 701 of the drilling assembly 7 pushes the push plate 703 to extend the drilling motor 704 fixed at the front end of the push plate 703 inside the component frame 701, so that the drill bit 705 contacts the workpiece 1 to be processed and drills the workpiece.

[0028] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
