Description

Technical Field

[0001] The invention belongs to the technical field of positioning design points of aircraft herringbone rims, and in particular is a rapid calibration workbench for design points of herringbone rims. Background Art

[0002] The wing herringbone rib is one of the important parts of an aircraft wing. For each herringbone rib part of a certain model, there are nearly 200 rib thickness dimensions that need to be measured. The part has a variable curvature and variable thickness structure. In order to accurately measure its thickness dimension, the measuring point must be located on the rib.

[0003] The traditional positioning method uses tools such as vernier calipers to manually measure and calculate the midpoint, and draw positioning lines on the product surface to determine the location of the measuring point. Since the upper edge plates of the wing rib fishbone rib parts are numerous and have no uniform size, the traditional method requires large amounts of measurement and calculation and is time-consuming. Marking positioning causes slight damage to the surface of the product, requiring subsequent grinding and finishing by fitters, which is not conducive to ensuring the surface quality of the product. In addition, the traditional measurement and positioning method requires staff to mark the points themselves, which is inefficient and slow to mark. Manual marking also has the potential for errors.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figures 1 to 10As shown, in an embodiment of the present invention, a fishbone edge strip design point rapid calibration workbench includes a sliding platform, a sliding mechanism 1, an elastic telescopic rod 2, a dotting tool 3, and a motor. Parallel guide rails are provided on both sides of the sliding platform along the length direction. The sliding mechanism is installed on the guide rails and can be moved to a specified position along the guide rails under the drive of the motor. The elastic telescopic rod is connected to the front end of the sliding mechanism and can be telescoped to the specified position along the width direction of the sliding platform. The dotting tool is connected below the front end of the elastic telescopic rod. The dotting tool moves to the specified position to mark the point on the product.

[0031] The dotting tool 3 includes a positioning body 31, a rotating piece 35, a fitting cover plate 32, an air supply mechanism 6, a first spring 33, a ball 34, a marking pen 5, and an ink cartridge 4. The top of the positioning body 31 is provided with an arc surface, and the positioning body 31 is engaged in the notch of the fishbone-shaped edge strip to be dotted. The rotating piece 35 is installed in the arc surface at the top of the positioning body 31. The end of the rotating piece 35 is provided with three slots 352 at an angle to each other, which can be selectively engaged with the first spring 33 and the ball 34 provided on the positioning body 31, so as to realize the rotation of the rotating piece 35 at a fixed angle in the arc surface. The fitting cover plate 32 covers the positioning body 31 and the rotating piece 35, the three are hinged into an integrated structure; the ink cartridge 4 is fixed on the fitting cover plate 32 and connected to the marking pen 5 through a conduit, a positioning hole 351 is provided at the outer end of the rotating piece 35 and a marking pen 5 is fixedly installed on the top of the positioning hole 351, and an air supply mechanism 6 is provided on the top of the fitting cover plate 32, and the air outlet end of the air supply mechanism 6 is connected to the marking pen 5 through a connecting pipe; the elastic piston inside the air supply mechanism 6 presses air into the marking pen 5, thereby pushing the elastic pressure rod in the marking pen 5 downward, and the sponge block 56 in the marking pen 5 passes through the positioning hole 351 and contacts the surface of the fishbone-shaped edge strip to make dots. The bottom of the rear end of the fitting cover plate 32 is fixedly installed with a roller 7

[0032] A groove is formed at the top of the positioning body 31 . The first spring 33 and the ball 34 are disposed in the groove. The ball 34 is pushed out to the opening of the groove by the first spring 33 and is engaged in the slot 352 .

[0033] The included angle between two adjacent slots 352 is 20 degrees.

[0034] The positioning body 31 includes a movable wheel 36 installed at the bottom thereof, and both side edges of the bottom of the positioning body 31 are configured as arc surfaces.

[0035] The marking pen 5 includes an elastic pressure rod, a sleeve 51, a limit block 55, and a sponge block 56. The limit block 55 is fixed on the inner wall of the sleeve 51, and the elastic pressure rod is installed inside the sleeve 51. The elastic pressure rod includes a first piston 52, a pressure rod 53 fixedly installed on the bottom end of the first piston 52, and a second spring 54 sleeved on the outside of the pressure rod 53. The sponge block 56 is fixedly installed on the bottom end of the pressure rod 53, and the second spring 54 is elastically supported between the first piston 52 and the limit block 55.

[0036] An exhaust hole 511 and an ink inlet 512 are provided on the surface of the sleeve 51 . The ink inlet 512 is connected to the ink cartridge 4 fixedly mounted on the top of the fitting cover plate 32 via a conduit. The connection between the conduit and the ink cartridge 4 is at a higher level than the ink inlet 512 .

[0037] When the sponge block 56 passes through the positioning hole 351 and contacts the fishbone-shaped edge strip, the cavity inside the sleeve 51 above the first piston 52 is communicated with the external environment through the exhaust hole 511 .

[0038] The air supply mechanism 6 includes a housing 61, an elastic piston, a support tube 62, a first one-way valve 66, and a second one-way valve 67. The elastic piston is installed inside the housing 61. The elastic piston includes a second piston 64, a slide rod 63 at the bottom end of the second piston 64, and a third spring 65 elastically connected to the top of the second piston 64. The support tube 62 is fixedly installed at the bottom of the housing 61. The slide rod 63 extends through the support tube 62 to the external environment. The support tube 62 and the bottom end of the roller 7 on the fitting cover plate 32 are located at the same level. Height, when the positioning body 31 is engaged in the notch of the fishbone-shaped edge strip, the roller 7 and the support tube 62 are supported on the surface of the fishbone-shaped edge strip, and the slide rod 63 is pushed by the surface of the fishbone-shaped edge strip to retract into the support tube 62. The air outlet end of the air supply mechanism 6 is a second one-way valve 67 fixedly installed on the top of the shell 61. A first one-way valve 66 is also fixedly installed on the top of the shell 61. The first one-way valve 66 is connected from top to bottom and blocked from bottom to top. The second one-way valve 67 is connected from bottom to top and blocked from top to bottom.

[0039] By comprehensively considering the working principle of the structure, it can be concluded that the gas exerting pressure on the first piston 52 will eventually be discharged from the exhaust hole 511, and when the dotting tool 3 is separated from the gap of the fishbone-shaped edge strip, the second piston 64 will move downward due to the elastic force of the third spring 65, thereby generating negative pressure. In order to prevent the air inside the sleeve 51 from being affected by the negative pressure, a one-way valve is provided on the top of the shell 61, so that the height of the first piston 52 rebounding due to the elastic force can be limited. The first one-way valve 66 is connected from top to bottom, and the gas in the external environment will enter the interior of the shell 61 along the first one-way valve 66.

[0040] The surface of the sleeve 51 is provided with an exhaust hole 511 and an ink inlet 512, and the ink inlet 512 is connected to the ink cartridge 4 fixedly mounted on the top of the fitting cover plate 32 through a conduit, and the connection between the conduit and the ink cartridge 4 is higher than the ink inlet 512;

[0041] The ink inlet 512 has a small aperture, and the oil film in the ink cartridge 4 will continue to pass through the ink inlet 512 along the conduit into the sleeve 51, and Figure 6 It can be seen that when the sponge block 56 has not moved down to the surface of the fishbone-shaped edge strip, it will absorb the ink flowing in along the ink inlet 512. When the sponge block 56 finally contacts the fishbone-shaped edge strip, the ink will be printed on the surface of the fishbone-shaped edge strip. Therefore, the cooperation between the ink inlet 512 and the ink cartridge 4 can continuously provide ink to the sponge block 56 to keep it moist.

[0042] When the sponge block 56 passes through the positioning hole 351 and contacts the surface of the fishbone-shaped edge strip, the cavity above the first piston 52 inside the sleeve 51 is connected to the external environment through the exhaust hole 511;

[0043] When the sponge block 56 comes into contact with the fishbone-shaped edge strip, the sponge block 56 will print ink on the surface of the fishbone-shaped edge strip. At this time, the first piston 52 is below the exhaust hole 511, so the inner cavity above the first piston 52 will be connected to the outside through the exhaust hole 511, and the high-pressure gas will be quickly discharged through the exhaust hole 511. When the pressure inside the sleeve 51 is released, the first piston 52 will move upward again due to the elastic force of the second spring 54, and the sponge block 56 will rebound immediately after contacting the fishbone-shaped edge strip in an instant, thereby avoiding;

[0044] In this way, the positioning points can be automatically marked without manual marking, and the ink is printed on the surface of the fishbone-shaped edge strip through instantaneous contact. After the dot is marked, the sponge block 56 rebounds quickly to prevent excessive ink or dragging of the line due to long-term contact with the fishbone-shaped edge strip.

[0045] The bottom of the positioning body 31 is provided with a movable wheel 36, and the two side edges of the bottom of the positioning body 31 are set as arc surfaces;

[0046] For example Figure 7 As shown, when the dotting tool 3 is engaged in the notch, the sliding mechanism 1 continues to drive the dotting tool 3 to move to the left, so that the notch slides along the arc surface of the bottom surface of the positioning body 31, and then the movable wheel 36 is slid to the edge of the notch, so that with the overall displacement of the slider, the dotting tool 3 can be flipped onto the top surface of the fishbone-shaped edge strip again, and then continue to move horizontally on the top surface of the fishbone-shaped edge strip;

[0047] like Figure 7As shown, when the dotting tool 3 rolls on the surface of the fishbone-shaped edge strip, the four fitting cover plates 32 at the bottom of the positioning body 31 provide rolling support. After the dotting tool 3 is engaged with the notch of the fishbone-shaped edge strip, the front end of the dotting tool 3 directly covers the surface of the fishbone-shaped edge strip through the rotating sheet 35, and the two sides of the dotting tool 3 are supported on the surface of the fishbone-shaped edge strip through the rollers 7 and the support tube 62. Therefore, in the process of moving to the notch of the fishbone-shaped edge strip, the dotting tool 3 as a whole can be stably supported.

[0048] In addition, after the dotting tool 3 is fully engaged with the fishbone-shaped edge strip notch, the support tube 62 and the roller 7 cooperate to support on both sides respectively. At this time, the slide rod 63 will be compressed and forced to retract completely into the support tube 62. Then, the elastic piston can press the air in the shell 61 into the sleeve 51 through the second one-way valve 67 to the maximum extent. Therefore, a necessary condition for realizing the above working process is that the moving direction of the dotting tool 3 must be consistent with the side where the roller 7 is located, which is also the case in the actual working process.

[0049] A groove is formed on the top of the positioning body 31, and the spring ball is a first spring 33 and a ball 34 disposed inside the groove. The ball 34 is pushed out to the opening of the groove by the first spring 33 and is engaged in the slot 352.

[0050] The first spring 33 gives elastic thrust to the ball 34. When the slot 352 is aligned with the ball 34, the ball 34 can be inserted into the slot 352, thereby limiting the position of the rotating piece 35 when it is not subjected to the axial force around the rotating axis, so that the angle is kept without deflection. When the angle of the rotating piece 35 needs to be adjusted, the staff directly rotates the rotating piece 35, and the slot 352 presses the ball 34 to compress the first spring 33, and at the same time, the ball 34 is pushed back, so that the ball 34 is inserted into another slot 352.

[0051] Thereby, the deflection angle of the rotating piece 35 can be adjusted very conveniently, and the deflection angle can also be maintained during the process of the overall horizontal displacement of the dotting tool 3 and the insertion into the notch.

[0052] There are three slots 352, and the angle between two adjacent slots 352 is 20 degrees. Since the fishbone-shaped edge strips of a certain type of aircraft are distributed with oblique notches with an oblique angle of 20 degrees, such as Figure 2 It can be seen that the approximate distribution pattern of the oblique notch, so if you want to locate its design point at this time, you need to turn back the corresponding rotating piece 35 responsible for locating the design point by 20 degrees. Therefore, we design a total of three slots 352, and the angle between two adjacent ones is 20 degrees.
