Description

Technical Field

[0001] This application relates to the technical field of aerospace component processing, specifically a positioning device for aerospace component processing. Background Art

[0002] During the processing of aerospace components, precise positioning is the key to ensuring component quality. Traditional positioning devices often have problems such as low positioning accuracy, complex operation, and poor adaptability, and cannot meet the processing requirements of high precision and high efficiency. Therefore, it is necessary to design a new type of precision positioning device to improve positioning accuracy and processing efficiency.

[0003] The Chinese utility model patent with application number CN202322933818.6 discloses a high-precision mechanical component processing positioning device, which relates to the technical field of component processing, including a base and a first lead screw rotatably connected inside the base. One end of the first lead screw is fixedly connected with a handwheel, and the outer circumferential surface of the first lead screw is rotatably connected with a first ball nut seat. The upper surface of the first ball nut seat is fixedly connected with a first connecting frame. Compared with the existing ordinary high-precision mechanical component processing auxiliary device, when using this high-precision mechanical component processing positioning device, the handwheel can be used to drive the first lead screw to rotate. The rotation of the first lead screw can drive the first connecting frame on the first ball nut seat to slide, thereby driving the positioning plate to slide and adjust on the upper surface of the base. This design is convenient for adjusting the position of the positioning plate and is convenient for positioning when mass-producing high-precision mechanical components. When processing parts of the same size, there is no need to repeatedly align and process, improving processing efficiency.

[0004] However, in actual use of the existing technology, since the components to be processed are manually fixed on the operating table by the staff, this fixing method has problems such as low positioning accuracy, complex operation, poor adaptability, and inability to clamp components of different shapes. And after the fixing is completed, it cannot be rotated and cannot perform multi-sided processing on the components. Therefore, the existing equipment needs to be improved.

The upper surface of the first mounting plate 2 is fixedly connected with a first motor 201, and the output shaft of the first motor 201 is fixedly connected with a first driving gear 202.

The upper surface of the third mounting plate 4 is fixedly connected with a third motor 401, and the output shaft of the third motor 401 is fixedly connected with a third driving gear 402;

[0033] The teeth of the first driving gear 202, the second driving gear 302 and the third driving gear 402 are respectively meshed with the teeth of the first driven gear 6, the second driven gear 7 and the third driven gear 8;

[0034] The upper surface of the first driven gear 6 is fixedly connected with a first connecting cylinder 601. The side surface of the first connecting cylinder 601 is fixedly connected with a first mounting ring 602. The outer side surface of the first mounting ring 602 is fixedly connected with a first connecting rod 603.

[0036] The upper surface of the third driven gear 8 is fixedly connected with a third mounting ring 801. The side surface of the third mounting ring 801 is fixedly connected with a third connecting rod 802. One end of the third connecting rod 802 far away from the third mounting ring 801 is rotatably connected with a third special-shaped plate 803;

[0037] The side surface of the fixed rod 5 is rotatably connected with the first connecting cylinder 601. The side surface of the first connecting cylinder 601 is rotatably connected with the second driven gear 7 and the inner wall of the second connecting cylinder 701. The side surface of the second connecting cylinder 701 is rotatably connected with the third driven gear 8 and the inner wall of the third mounting ring 801. One ends of the first special-shaped plate 604, the second special-shaped plate 704 and the third special-shaped plate 803 far away from the first connecting rod 603, the second connecting rod 703 and the third connecting rod 802 are rotatably connected with the outer surface of the processing table 9;

[0038] When precise machining of a certain direction of a component is required, at this time, the staff starts the first motor 201, the second motor 301 or the third motor 401. At this time, the first driving gear 202, the second driving gear 302 and the third driving gear 402 will rotate. And through the limitation of the fixed rod 5, the first driven gear 6, the second driven gear 7 and the third driven gear 8 can be rotated. Through the cooperation between the first connecting cylinder 601, the second connecting cylinder 701 and the third mounting ring 801, the first connecting rod 603, the second connecting rod 703 and the third connecting rod 802 can perform circular trajectory displacement. The displacement of the first connecting rod 603 and the second connecting rod 703 is completed through the transmission of the first mounting ring 602 and the second mounting ring 702. And through the displacement of the first connecting rod 603, the second connecting rod 703 and the third connecting rod 802, the first special-shaped plate 604, the second special-shaped plate 704 and the third special-shaped plate 803 can be further made to perform circular trajectory displacement, so as to finally achieve the purpose of adjusting the orientation of the processing table 9, thus solving the problem that since the staff manually fixes the component to be processed on the operating table, it cannot be rotated after being fixed, and multi-sided processing of the component cannot be carried out;

[0039] On one side where two first clamping blocks 10 are close to each other, a first sliding ring 12 is slidably connected. There are four first sliding rings 12. The inner sides of the four first sliding rings 12 are fixedly connected with second clamping blocks 13. On one side where the four second clamping blocks 13 are close to each other, a second sliding ring 14 is slidably connected. There are eight second sliding rings 14. The inner sides of the eight second sliding rings 14 are fixedly connected with third clamping blocks 15;

[0040] On one side where the eight third clamping blocks 15 are close to each other, anti-slip patterns 16 are provided. On the side of the fixing plate 902 close to the sliding groove 901, a cylinder 903 is fixedly connected. The output shaft of the cylinder 903 is fixedly connected with the curved side surface of the first clamping block 10 close to the sliding groove 901;

[0041] When the staff needs to clamp a component, start the cylinder 903. At this time, one of the first clamping blocks 10 will perform reciprocating displacement in the horizontal direction towards the other first clamping block 10. This displacement is completed through the cooperation of the sliding groove 901 and the slider 11. When the two first clamping blocks 10 contact the object, at this time, the second clamping blocks 13 and the third clamping blocks 15 will move towards the direction of fitting the surface of the object. This movement is completed through the sliding between the first sliding ring 12 and the first clamping block 10 and the sliding between the second sliding ring 14 and the second clamping block 13. In this way, the problems that since the staff manually fixes the component to be processed on the operating table, this fixing method has low positioning accuracy, complex operation, poor adaptability, and cannot clamp components of different shapes are solved.
