[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0028] It should be understood that in the description of this application, the terms "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used solely for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. That is, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Furthermore, unless otherwise stated, "a plurality of" means two or more.
[0029] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0030] The repair of aircraft seat rails involves cutting off the corroded section of the rail and replacing it with a new one. The cut section is then joined using an overlap strip (aluminum alloy profile). New holes need to be drilled in the overlap strip, and the rails are then fastened together with fasteners (rivets or screws).
[0031] During the repair process, drilling new holes in the vertical plane formed by the overlap strip 8 and the cabin seat rail is crucial, as the drilling quality directly affects the component installation quality. The drilling locations are mainly concentrated on the Z-plane of the overlap strip. This area lacks guide holes and reference holes, and drilling must be carried out at the aircraft's installation location. Traditional manual drilling methods often use right-angle pneumatic drills and rely on manually drawn dimensional lines. Therefore, the shape and position of the drilled holes are prone to deviation, which in turn affects the assembly accuracy and structural strength of the components.
[0032] like Figures 1-3 As shown, the aircraft seat slide rail repair drilling device of this utility model includes a bracket 1, a positioning component 2, a Y-axis guide rail 3, an X-axis guide rail 4, a Z-axis guide rail 5, a mounting base 6, and a right-angle drill 7. During operation, the overlapping strap 8 is fixed to the bracket 1 by the positioning component 2. The positions of the right-angle drill 7 in the Y, X, and Z directions are adjusted by the Y-axis guide rail 3, X-axis guide rail 4, and Z-axis guide rail 5 respectively, so that the drill bit of the right-angle drill 7 can accurately drill holes in the overlapping strap 8.
[0033] The bracket 1 includes two sets of spaced clamping bodies 11. The upper part of the clamping body 11 has a clamping groove 111 for accommodating the overlapping strap 8, and the lower part of the clamping body 11 has a mounting surface 112. The mounting surface 112 is used to mount the Y-axis guide rail.
[0034] One end of the positioning member 2 passes through the upper part of the clamping body 11 and abuts against the overlapping strip 8, thereby defining the position of the overlapping strip 8 in the clamping groove 111. For example, the positioning member 2 is a knob bolt, with one end of the knob bolt passing through the screw hole on the clamping body 11 and abutting against the overlapping strip 8 to fix the position of the overlapping strip 8.
[0035] The two ends of the Y-axis guide rail 3 are respectively installed on the mounting surfaces 112 of the two sets of clamping bodies 11. The X-axis guide rail 4 is slidably installed on the Y-axis guide rail 3, the Z-axis guide rail 5 is slidably installed on the Y-axis guide rail 4, the mounting base 6 is slidably installed on the surface of the Z-axis guide rail 5 near the overlapping strip 8, and the right angle drill 7 is installed on the mounting base 6, and the drill bit of the right angle drill 7 is used to drill holes in the overlapping strip 8.
[0036] Based on the above structural design, the right-angle drill 7 can move along the X, Y, and Z directions, facilitating position adjustment and improving drilling accuracy. This, in turn, enhances dimensional tolerances, form and position tolerances, and hole wall quality, thereby effectively optimizing drilling quality and improving fatigue resistance.
[0037] like Figure 1 As shown, in some embodiments, the right-angle drill 7 is a pneumatic right-angle drill. Using the right-angle drill 7 can reduce the space occupied and can be used normally in a smaller space.
[0038] like Figure 1 and 2 As shown, in some embodiments, the Y-axis guide rail 3 includes a first track 31 and a first slider 32 slidably mounted on the first track 31. The two ends of the first track 31 are respectively mounted on the mounting surfaces 112 of the two sets of clamping bodies 11. Thus, the Y-axis position can be adjusted by sliding the first slider 32 on the first track 31.
[0039] In some embodiments, the Y-axis guide rail 3 includes a first bolt 33, the shank of which is mounted on the first slider 32, and the head of which abuts against the first track 31. Thus, tightening the first bolt 33 fixes the position of the first slider 32 on the first track 31, and loosening the first bolt 33 allows the position of the first slider 32 on the first track 31 to move.
[0040] like Figure 2 and 3 As shown, in some embodiments, the X-axis guide rail 4 includes a second rail 41 and a second slider 42 slidably mounted on the second rail 41, with the second rail 41 mounted on the first slider 32. Thus, by sliding the second slider 42 on the second rail 41, the X-axis position can be adjusted.
[0041] Furthermore, the X-axis guide rail 4 includes a second bolt 43, the shank of which is mounted on the second slider 42, and the head of which abuts against the second rail 41. Thus, tightening the second bolt 43 fixes the position of the second slider 42 on the second rail 41, and loosening the second bolt 43 allows the second slider 42 to move on the second rail 41.
[0042] like Figure 2 and 3 As shown, in some embodiments, the Z-axis guide rail 5 includes a third rail 51 and a third slider 52 slidably mounted on the third rail 51, with the third rail 51 mounted on the second slider 42. Thus, Z-axis position adjustment is achieved by sliding the third slider 52 on the third rail 51.
[0043] Furthermore, the Z-axis guide rail 5 includes a third bolt 53, the shank of which is mounted on the third slider 52, and the head of which abuts against the third rail 51. Thus, tightening the third bolt 53 fixes the position of the third slider 52 on the third rail 51, and loosening the third bolt 53 allows the third slider 52 to move on the third rail 51.
[0044] like Figure 2As shown, in some embodiments, the Z-axis guide rail 5 includes a reinforcing block 54. The side of the reinforcing block 54 is connected to the side of the third rail 51 opposite to the third slider 52, and the bottom of the reinforcing block 54 is mounted on the second slider 42. The reinforcing block 54 can maintain the stability of the mounting position of the third rail 51 on the second slider 42.
[0045] In some embodiments, scale lines are provided on the sides of the first track 31, the second track 41, and the third track 51. The scale lines facilitate accurate adjustment of the positions of the first slider 32, the second slider 42, and the third slider 52.
[0046] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
