Description

Technical Field

[0001] This invention belongs to the field of aircraft seat slide rail assembly technology, specifically relating to a fixture for assembling aircraft pilot seat slide rails and its usage method. Background Technology

[0002] The aircraft pilot's seat is mounted on floor rails in the cockpit. During seat rail assembly, the relative positions of the two rails must first be determined, then the mounting positions of the two rails on the cockpit floor must be identified, and holes must be drilled in the floor according to the positions of the rail mounting holes. Finally, the rails are secured to the cockpit floor using screws, nuts, and washers.

[0003] The seat base incorporates a reliable slide rail locking mechanism. When the slide rail locking handle is turned, the locking pin disengages from the slide rail pin hole, allowing the seat to move back and forth. When the handle is released, the locking pin automatically engages with the slide rail pin hole under spring tension, preventing further movement of the seat. To ensure smooth sliding and quick stopping of the seat on the slide rails, precise positioning of the two slide rails during assembly is crucial. Summary of the Invention

[0031] Furthermore, the pressure plate 4 is bent at both ends, with one end pressing on the bracket 2 and the other end pressing on the outer side of the slide rail 13.

[0032] Furthermore, the knurled nut 5 is a standard part, model JB / T 8004.5-1999; the pin 10 is a standard part, model HB1868-87.

[0033] This invention provides a method for using a fixture for assembling an aircraft pilot seat slide rail 13, comprising the following steps: Assemble the fixture; Insert a slide rail 13 into one side of the fixture, and use a positioning pin 7 to pass through the elongated hole of the angle plate 6 and insert it into the pin hole on the slide rail 13. Rotate the knurled nut 5 to make the pressure plate 4 press against the slide rail 13, thereby pressing the slide rail 13 against the limit pin 9; Insert the other slide rail 13 into the other side of the fixture in the same manner; After clamping, align the slide rail 13 on the floor 14 according to its installation position. Make matching holes on the floor 14 according to the position of the mounting holes of the slide rail 13. After tightening the connection, remove the clamp.

[0034] Example 2 This invention provides a fixture for assembling aircraft pilot seat slide rails, comprising a tube frame 1, a bracket 2, a plate 3, a pressure plate 4, a knurled nut 5, a corner plate 6, a locating pin 7, a guide seat 8, a limiting pin 9, a pin 10, a bolt 11, and a nut 12. This fixture can position the relative positions of two slide rails. The bracket 2 and corner plate 6 ensure that the top surfaces of the two slide rails are on the same plane; the locating pin 7 ensures that the front surfaces of the two slide rails are on the same plane; and the limiting pin 9 and pressure plate 4 define the distance between the two slide rails.

[0035] Pipe rack 1 is made of 7 steel pipes welded together, three horizontally and four vertically.

[0036] Support 2 is welded to the end faces of the first and third transverse steel pipes of pipe rack 1. Support 2 has studs on one side. The other side of support 2 has two through holes for connecting guide seats 8.

[0037] Plate 3 is welded to the end face of the second transverse steel pipe of pipe rack 1. Plate 3 has two through holes for connecting corner plate 6.

[0038] The pressure plate 4 has a through hole in the middle, is installed on the stud of the bracket 2, and then tightened with the knurled nut 5.
