[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0020] according to Figure 1-2As shown, an automatic diameter detection device for an aircraft cylinder damper comprises a base plate 1, a fixed bracket 2 is fixedly installed on one side of the base plate 1 by screws, a first spring hook 4 is installed on the top of one side of the fixed bracket 2, a through groove is provided at the bottom of the fixed bracket 2, a movable bracket 3 is provided on the other side of the fixed bracket 2, a guide rail 13 is provided between the fixed bracket 2 and the movable bracket 3, the movable bracket 3 is slidably installed on the fixed bracket 2 through the guide rail 13, a second spring hook 5 is slidably installed in the through groove of the fixed bracket 2, one end of the second spring hook 5 is fixedly installed on the movable bracket 3, a spring 6 is installed between the first spring hook 4 and the second spring hook 5, a digital micrometer 8 is installed on the top of the movable bracket 3, a mounting hole 12 is provided at the bottom of the movable bracket 3, a shaft sleeve 10 is provided in the mounting hole 12 through a top screw 11, and a measuring head 9 is fixedly installed in the shaft sleeve 10.
[0021] A bottom plate groove 7 is formed on the bottom plate 1 , and the bottom plate groove 7 is arranged below the movable bracket 3 , and the length and width of the bottom plate groove 7 are slightly larger than the length and width of the bottom of the movable bracket 3 .
[0022] The bottom of the movable bracket 3 is movably installed in the bottom plate groove 7, the upper surface of the bottom of the movable bracket 3 is not higher than the upper surface of the bottom plate 1, the measuring head 9 is slightly higher than the upper surface of the bottom plate 1, and the damper 14 to be tested is placed flat on the bottom plate 1. The damper to be tested moves from the bottom plate 1 to the movable bracket 2 to make the movable bracket 2 float, thereby ensuring the normal operation of the digital micrometer and the measuring head.
[0023] The movable bracket 3 is in a U-shape rotated 90° clockwise, and the closed end of the movable bracket 3 is slidably mounted on the fixed bracket 2 on the left side through the guide rail 13. The distance from the inner wall of the movable bracket 3 to the axis of the damper 14 to be detected must be greater than the radius of the damper 14 to be detected, and the open end of the movable bracket 2 is on the right side.
[0024] The probe of the digital micrometer 8 and the measuring head 9 in the bottom mounting hole 12 of the movable bracket 3 are arranged opposite to each other, and the probe and the measuring head 9 cooperate with each other. The distance between the probe and the measuring head 9 is slightly smaller than the diameter of the damper 14 to be tested, and the distance between the probe and the measuring head 9 needs to be measured by a standard measuring block.
[0025] The position where the second spring hook 5 and the movable bracket 3 are fixedly installed is located below the guide rail 13 , and such an arrangement can ensure the normal operation of the guide rail 13 .
[0026] The top surface of the measuring head 9 passes through the mounting hole 12, and the top surface of the measuring head 9 is slightly higher than the top of the mounting hole 12. This arrangement can ensure that the measuring head 9 is in contact with the outer circumferential surface of the damper 14 to be measured.
[0027] Working principle: the digital micrometer 8 is first cleared, the damper 14 to be tested is placed on the base plate 1, and then the damper 14 to be tested is pushed into the movable bracket 3 through the opening area of the movable bracket 3. Under the gravity of the damper 14 to be tested, the movable bracket 3 falls, and the measuring head 9 at the lower end of the movable bracket 3 is flush with the upper surface of the base plate 1. The damper 14 to be tested passes through the measuring head 9 and the measuring head of the digital micrometer 8, and the maximum reading of the digital micrometer 8 is obtained during the pushing process. The initial distance between the measuring head of the digital micrometer 8 and the measuring head 9 is L. The accurate number of L needs to be calibrated by a standard measuring block. The actual diameter of the damper = L + the maximum reading of the digital micrometer 8.
[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
