Description

Transition tape cutting machine

Technical Field

The invention relates to the field of transition tape production, in particular to a transition tape cutting machine.

Background

When a real airplane flies in the air, because the flying Reynolds number is very high, boundary layers on the surfaces of all parts of the airplane are almost in a turbulent flow state. In the wind tunnel test, because the test Reynolds ratio is lower, a section of laminar boundary layer is quite long on the surface of the model, and the state of the boundary layer on the surface of the model is greatly different from that of a real airplane. This difference complicates and randomizes the effect of reynolds number in wind tunnel experiments. If the method of artificial fixation transition of the boundary layer is adopted during model test, so that the boundary layer of the model surface is similar to the plane, the modification of the Reynolds number influence can be greatly simplified.

The artificial transition is to artificially introduce some disturbance sources (roughness elements) at a certain position on the surface of the test model to force the boundary layer to transition from the laminar flow to the turbulent flow.

In a wind tunnel test, a commonly used method for transition is to paste silicon carbide, micro glass balls, sawtooth copper sheets or columnar rough elements on the surface of a model, and the strip rough elements pasted on the transition position of the model from laminar flow to a turbulent flow boundary layer are called transition strips.

And the rough element on the transition strip needs to be precisely controlled, so that the initially preset rough element can be ensured to correspond to the result obtained by the wind tunnel experiment, and an effective conclusion is obtained.

The vertical displacement of the galvanometer assembly 230 is realized through a vertical motor, in some other embodiments, the vertical movement motor 131 occupies the mirror holder 210, and therefore, the mirror holder 210 and the galvanometers in the galvanometer assembly 230 are laterally displaced to a certain extent; in these embodiments, galvanometer assembly 230 includes an adjustment mirror and a galvanometer; the adjusting mirror is disposed at one side of the vibrating mirror, the exit end of the mirror frame 210 faces the adjusting mirror, and the exit end of the adjusting mirror faces the vibrating mirror.

In this embodiment, the tape transition cutting carrier 030 includes a frame 300 and a carrier portion;

an installation space with an open top is formed in the frame body 300, the bearing part is arranged in the installation space of the frame body 300, and a negative pressure port 310 for connecting a negative pressure device is further arranged on one side of the frame body 300;

referring to fig. 2, 4 and 5, the carrying part includes an adsorption net plate 410 and a positioning assembly, the positioning assembly includes a telescopic rod 431 and a supporting plate 433;

one end of the telescopic rod 431 is fixed with the supporting plate 433, and the other end is fixed relative to the frame body 300, so that the supporting plate 433 can be relatively close to or far away from the top opening; an adsorption screen 410 for carrying a transition tape is placed on the supporting plate 433.

The adsorption screen plate 410 is supported on the support plate 433 by its own weight, and then the up-and-down movement of the adsorption screen plate 410 is realized by driving the support plate 433 up and down. Wherein, a negative pressure supply system capable of being externally connected and matched is arranged through the negative pressure port 310.

In order to conveniently place articles such as consumables, a drawer 500 is arranged on one side outside the frame body 300; the drawer 500 can be relatively close to or far from the frame 300. At ordinary times, a large amount of consumables can be placed in the drawer 500, and the consumables can be taken out of the drawer 500 in use. The bottom of the drawer 500 is further provided with a sliding rail 510, and the drawer 500 is slidably engaged with the sliding rail 510.

In the present embodiment, the sliding rail 510 is a rodless cylinder for opening the drawer 500. Manpower can be saved by driving the drawer 500 by the rodless cylinder.

In order to position the height of the adsorption screen plate 410 and perform laser cutting on the adsorption screen plate 410 at a preset height, the bearing part further comprises a positioning assembly;

the positioning assembly comprises a displacement expansion pair 451 for displaying the displacement of the supporting plate 433 in an expanded manner, and a displacement sensing pair 453 for measuring the displacement of the displacement expansion pair 451.

Referring to fig. 6, 7 and 8, in particular, the shift enlarging pair 451 includes a horizontal positioning rail 4511, a diagonal positioning rail 4513 and a diagonal slider 4515;

a horizontal positioning rail 4511 is fixed at the bottom of the installation space; the oblique positioning rail 4513 is in sliding fit with the horizontal positioning rail 4511 so that the horizontal positioning rail 4511 can slide horizontally;

a diagonal slider 4515 is slidably disposed on a side of the diagonal positioning rail 4513 remote from the horizontal positioning rail 4511; the inclined slide block 4515 is fixedly connected with the bearing plate 433.

When the telescopic rod 431 extends and retracts in the height direction, the supporting plate 433 is driven to move up and down, the supporting plate 433 also drives the inclined sliding block 4515 to move up and down, and the inclined sliding block 4515 is connected with the inclined positioning rail 4513, so that the inclined sliding block 4515 moves up and down and also moves horizontally relative to the inclined positioning rail 4513, but in this embodiment, because the upper end and the lower end of the telescopic rod 431 are fixedly connected but not hinged, the inclined sliding block 4515 cannot move horizontally relative to the telescopic rod 431 (the connection point between the telescopic rod 431 and the supporting plate 433 and the connection point between the inclined sliding block 4515 and the supporting plate 433 are kept relatively fixed through the rigid supporting plate 433), and at this time, the horizontal position of the inclined sliding block 4515 needs to be kept stable through the horizontal displacement inclined positioning rail 4513. The diagonal positioning rail 4513 thus slides horizontally relative to the horizontal positioning rail 4511. At this time, the vertical displacement of the oblique slider 4515 is reflected on the horizontal displacement of the oblique positioning rail 4513, and the vertical displacement of the oblique slider 4515 can be indirectly measured by measuring the horizontal displacement of the oblique positioning rail 4513.

Referring to fig. 9 and 10, in order to measure the horizontal displacement of the inclined positioning rail 4513, the displacement sensing pair 453 includes a blocking piece 4531 and a plurality of photosensitive pieces 4533 arranged at intervals; the blocking piece 4531 is fixedly arranged on one side of the inclined positioning rail 4513;

the photosensitive member 4533 is fixedly disposed at the bottom of the installation space, and one side thereof is used for sensing the stopper 4531.

When the blocking piece 4531 is horizontally displaced to the position of the photosensitive member 4533, the photosensitive member 4533 sends an electric signal to determine the horizontal position of the inclined positioning rail 4513 and indirectly determine the height position of the inclined slide 4515 (and the supporting plate 433).

In order to adjust the adsorption capacity of the adsorption screen plate 410, a negative pressure adjusting assembly is further included; the negative pressure adjusting assembly comprises a driving motor 610 and a driving rod 630 which are arranged at the bottom of the installation space; the end of the driving rod 630 remote from the driving motor 610 is used for installing a baffle which can be relatively close to or remote from the negative pressure port 310.

In practical use, the driving motor 610 drives the driving rod 630 to axially displace, and the blocking piece 4531 mounted on the driving rod 630 is close to the negative pressure port 310 through the axial displacement of the driving rod 630 to weaken the negative pressure adsorption force or is far away from the negative pressure port 310 to improve the negative pressure adsorption force, so that the adjustment of the negative pressure adsorption force is realized.

Through the transition tape cutting machine provided by the invention, the transition tape cutting carrier 030 can provide continuous and stable support and adsorption for transition tape cutting, so that the transition tape cutting process is kept smooth and stable. And the vertical displacement of the adsorption screen plate 410 is reflected to the horizontal displacement, so that the arrangement of a displacement monitoring system can be facilitated, and the displacement can be amplified to carry out accurate control. The transition tape cutting laser emission aligning device 010 can effectively and continuously inject laser emitted by a laser into a vibrating mirror capable of moving on a vertical surface, and the light path of the laser can be finely adjusted according to actual installation conditions through the adjustable reflector bracket 210. The dust removing member 231 provided on the galvanometer can move synchronously with the galvanometer to remove dust on the part to be laser-cut.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
