[0027] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.
[0028] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.
[0029] The following describes an aircraft rudder and steering gear test bench that is easy to move and position, provided by some embodiments of the present invention, in conjunction with the accompanying drawings.
[0030] Example 1:
[0031] Combine Figure 1-6 As shown, the aircraft rudder and steering gear test bench provided by the present invention, which is easy to move and position, includes a support mechanism 100 and an adjustment mechanism 200. The support mechanism 100 includes a U-shaped base 110, a plurality of springs 120 embedded in the inner side walls of the U-shaped base 110, a slider 130 connected to the bottom end of the spring 120, a lifting plate 140 connected between two adjacent sliders 130, and a horizontal platform 150 connected between the two lifting plates 140. The inner side walls of the U-shaped base 110 are each provided with two sliding grooves suitable for lifting and lowering the sliders 130.
[0032] The adjusting mechanism 200 includes a motor 210 embedded in the bottom of the U-shaped base 110, a gear 220 sleeved on the outside of the output shaft of the motor 210, two tooth plates 230 meshing with the gear 220, a clamping sleeve 240 clamped to one end of the tooth plate 230, and a gentle slope 250 installed on one side of the clamping sleeve 240, and the lifting plate 140 is located at the top of the gentle slope 250.
[0033] Furthermore, the thickness of the gear 220 is equal to that of the tooth plate 230 , and both fit in with the bottom of the inner cavity of the U-shaped base 110 . With this size and layout design, the gear 220 and the tooth plate 230 fit more stably.
[0034] Furthermore, the two tooth plates 230 are vertically symmetrical about the gear 220, and the two tooth plates 230 slide in opposite directions. With this structural design, the two gentle slopes 250 can move in opposite directions, and then the two lifting plates 140 can be lifted and lowered at the same time.
[0035] Furthermore, two pads 300 are installed at the bottom of the U-shaped base 110. The two pads 300 are vertically symmetrical about the motor 210. The thickness of the pads 300 is greater than the height of the motor 210. The pads 300 can be set to raise the U-shaped base 110 so that the motor 210 can be installed smoothly.
[0036] Furthermore, two rollers 400 are installed at the bottom of the lifting plate 140. The two rollers 400 are both attached to the top of the inclined surface. The rollers 400 are provided to facilitate the lifting of the lifting plate 140.
[0037] Example 2:
[0038] Combine Figure 1 and Figure 4-6 As shown, based on the first embodiment, the top of the gentle slope 250 is set as an inclined surface, and a convex plate is integrally formed at the outer end. The convex plate can prevent the roller 400 from sliding off the inclined surface.
[0039] Example 3:
[0040] Combine Figure 1 、 4 and Figure 6 As shown, in the above embodiment, a socket suitable for the tooth plate 230 to be plugged in is provided on the inner side of the gentle slope 250. The provision of the socket can expand the moving distance of the tooth plate 230 and enable the gentle slope 250 to move outward to the maximum extent.
[0041] The working principle and usage process of the present invention are as follows: when controlling the horizontal platform 150 to be lifted to the required height, the on-site technician starts the motor 210, and then the gear 220 rotates. Under mechanical transmission, the tooth plate 230 pushes the sleeve 240 and the gentle slope 250 to move outward, and then the gentle slope 250 squeezes the roller 400, and then multiple rollers 400 and two lifting plates 140 cooperate to realize the rise of the horizontal platform 150. Then, after the horizontal platform 150 reaches the required height, the motor 210 is turned off, thereby fixing the horizontal platform 150.
[0042] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
