Description

Technical Field

[0001] This utility model is a locator component for an aircraft assembly fixture, belonging to the field of positioning equipment technology. Background Technology

[0002] The commonly used installation method for aircraft assembly fixture locator components is to use a laser tracker for adjustment. Three holes that are not in a straight line are designed on the locator. The target object of the laser tracker is placed on the holes of the locator in sequence. By adjusting the position of the locator, the coordinate value displayed on the laser tracker screen is made close to the coordinate value of the point given in the design drawing until the error is controlled between 0.05-0.1mm. This completes the installation of the locator.

[0003] Publication number CN221699030U mentions a locator assembly for an aircraft assembly fixture. This assembly allows for simple and precise adjustment by adding an adjusting element and shims next to the locator. Adjustments in the X, Y, and Z directions of the locator can be performed using this method. This method of installing and adjusting the locator is simple and quick, requiring no repetitive operations, and offers higher precision and ease of operation compared to traditional technologies. However, the locator in this device is bolted to the assembly fixture frame connector, fixing its position and preventing adjustment according to actual positioning requirements. This results in a limited positioning range after installation. Therefore, there is an urgent need for a locator assembly for aircraft assembly fixtures to address these issues. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a locator assembly for aircraft assembly fixtures, thereby solving the problems mentioned in the background section. This invention adopts a hand-tightening movable structure, which enables the position adjustment of the locator. In addition, it is equipped with a spring-push-lock anti-loosening structure, which can lock and limit the locator after the position adjustment is completed, preventing it from easily shifting due to external influences and ensuring accurate positioning of the subsequent aircraft assembly fixture.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a positioning device assembly for an aircraft assembly fixture, comprising a fixture connecting plate, a threaded rod, a bending plate, and an anti-loosening push rod. A fixed side plate is bolted to the upper right side of the fixture connecting plate, a bearing seat is installed through the left end of the fixed side plate, the threaded rod passes through the bearing seat, and a nut sleeve is screwed onto the outside of the threaded rod. A fixed rail is bolted to the upper end of the fixture connecting plate, a slide rail groove is provided at the upper end of the fixed rail, and a horizontal limit is fixed at the lower end of the nut sleeve. The block has a bending plate welded to its rear end. A locator is longitudinally fixed to the rear end of the bending plate by bolts. The locator has multiple placement holes on its surface, three of which are fitted with laser trackers. A cylindrical hole is formed through the upper end of the bending plate, and a fixing ring is horizontally fixed inside the upper end of the cylindrical hole. The anti-loosening push rod slides through the fixing ring. A spring is installed at the lower end of the fixing ring. A spring plate is horizontally fixed to the lower end of the anti-loosening push rod. The lower end of the spring is fixed to the spring plate. An anti-slip plate is fixed to the lower end of the anti-loosening push rod.

[0006] Furthermore, a hand grip block is fixed to the right end of the threaded rod.

[0007] Furthermore, the limiting block is slidably located within the slide rail groove.

[0008] Furthermore, two triangular ribs are welded at the bend of the bent plate.

[0009] Furthermore, a fixing pin is fixed through the upper side of the front end of the anti-loosening push rod.

[0010] Furthermore, the anti-slip sheet abuts against the rear upper side of the clamp connecting plate.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a locator assembly for an aircraft assembly fixture. Because it incorporates a fixed side plate, bearing seat, threaded rod, nut sleeve, fixed rail, limit block, bending plate, locator, laser tracker, anti-loosening push rod, fixing ring, spring, spring plate, anti-slip plate, and fixing pin, our design improvements and practical use have shown that this device has a reasonable structure and good practicality. The hand-tightening movable structure enables position adjustment of the locator, and the spring-push-lock anti-loosening structure locks and limits the locator after position adjustment, preventing it from easily shifting due to external influences and ensuring accurate positioning of the subsequent aircraft assembly fixture.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-3 This utility model provides a technical solution: a positioning device assembly for an aircraft assembly fixture, including a fixture connecting plate 1, a threaded rod 5, a bent plate 10, and an anti-loosening push rod 15. A fixed side plate 2 is bolted to the upper right side of the fixture connecting plate 1, and a bearing seat 3 is installed through the left end of the fixed side plate 2. The threaded rod 5 passes through the bearing seat 3, and a nut sleeve 6 is screwed onto the outside of the threaded rod 5. A fixed rail 7 is bolted to the upper end of the fixture connecting plate 1, and a slide rail groove 8 is provided on the upper end of the fixed rail 7. A limit block 9 is horizontally fixed to the lower end of the nut sleeve 6, and a bent plate 10 is welded to the rear end of the limit block 9. A positioning device 12 is longitudinally fixed to the rear end of the bent plate 10 by bolts, and a positioning device 12 is provided on the surface of the positioning device 12. Multiple placement holes 13 are provided, three of which are fitted with laser trackers 14. A cylindrical hole is provided through the upper end of the bent plate 10, and a fixing ring 16 is horizontally fixed inside the upper end of the cylindrical hole. The anti-loosening push rod 15 slides through the fixing ring 16. A spring 17 is installed at the lower end of the fixing ring 16. A spring plate 18 is horizontally fixed at the lower end of the anti-loosening push rod 15. The lower end of the spring 17 is fixed to the spring plate 18. An anti-slip plate 19 is fixed at the lower end of the anti-loosening push rod 15. This design solves the problem that in the original device, the positioner is installed on the assembly fixture frame connector by bolts, and its position is fixed and cannot be adjusted according to the actual positioning requirements, thus limiting its positioning range after installation.

[0019] In the first embodiment of this utility model: a hand grip block 4 is fixed to the right end of the threaded rod 5, which facilitates the rotation of the threaded rod 5 by the assembly personnel. The limiting block 9 slides within the slide rail groove 8, which limits the movement of the limiting block 9 and the nut cylinder 6, preventing the nut cylinder 6 from rotating. Two triangular ribs 11 are welded to the bending point of the bent plate 10, which improves the overall strength of the bent plate 10.

[0020] A fixing pin 20 is fixed through the upper front end of the anti-loosening push rod 15. The added fixing pin 20 makes it easy for the assembly personnel to lift the anti-loosening push rod 15. The anti-slip plate 19 abuts against the rear side of the upper end of the clamp connecting plate 1. By abutting against the rear side of the upper end of the clamp connecting plate 1, the anti-loosening push rod 15 can limit the bending plate 10, so that the bending plate 10 will not easily vibrate.

[0021] As a second embodiment of this utility model: In actual use, slightly lift the fixing pin 20 with one hand, and the anti-loosening push rod 15 will be driven to move upward within the fixing ring 16, thereby making the lower end of the anti-slip plate 19 no longer in contact with the upper end of the clamp connecting plate 1. At the same time, the spring 17 will also be driven to compress upward. Twist the handle block 4 with the other hand, and the handle block 4 will drive the threaded rod 5 to rotate in place within the bearing seat 3, thereby causing the nut sleeve 6 to move to the left outside the threaded rod 5 through the thread principle. During this process, the bending plate 10 will also be driven to move to the left, thereby changing the position of the positioner 12, and thus changing the position of the three laser trackers 14, so as to facilitate position adjustment according to actual positioning requirements. After the adjustment is completed, release the fixing pin 20, and the spring 17 will return to its original position, which will drive the anti-loosening push rod 15 to move down again until the anti-slip plate 19 and the upper rear side of the clamp connecting plate 1 are back together, which facilitates the accurate positioning of the three laser trackers 14.
