Description

Technical Field

[0001] The utility model belongs to the structural technical field of aircraft products, and relates to a simple device for measuring the position of a rudder surface lock body. Background Art

Content of the Utility Model

[0003] Purpose of the Utility Model

[0004] The utility model overcomes the deficiencies in the prior art and can intuitively measure the relative distance dimension between the rudder surface lock body and the stabilizer surface when the rudder surface is in the neutral state.

[0005] Technical Solution

[0006] A simple device for measuring the position of a rudder surface lock body includes a measuring body 1, a stop block 3, a guide rod 4, and a support 5. The measuring body 1 is of a plate-like structure. On one side of the plate-like structure, there is a pin 2 for fixing the stabilizer surface of the product 7. At the central position of the measuring body 1, there are successively arranged a stop block 3, a guide rod 4, and a support 5. The guide rod 4 is provided with threads and is screwed with a nut 6 on the support 5. After passing through the support 5, the guide rod 4 is connected to the stop block 3 by a screw. The guide rod 4 is provided with a guide groove that cooperates with and guides a protrusion on the support 5. By rotating the nut 6 at the end of the guide rod 4, the guide rod 4 moves and drives the stop block 3 to translate, achieving the purpose of measuring the intersection point of the lock body and the stabilizer surface of the product 7.

[0007] Further, a notch is provided on the measuring body 1, and a protrusion on the stop block 3 cooperates with the notch to guide the stop block 3.

[0008] Further, a convex platform is provided on the surface of the stop block 3 that is in contact with the product 7, and the convex platform is inserted into the lock groove of the lock body of the product 7 to play a positioning and fixing role.

[0009] Further, the height of the convex platform should be less than the depth of the lock groove.

[0010] Further, the outer shape of the surface of the stop block 3 that is in contact with the product 7 fits the surface outer shape of the product 7.

[0011] Further, there are two pins 2, which are symmetrically distributed on one side of the measuring body 1 for positioning the stabilizer surface of the product 7.

[0012] The beneficial effects of this application are as follows:

[0013] The utility model provides a simple measurement means, which can simply measure the dimension between the lock body and the stabilizer surface, and detect the installation quality of the product in advance. At the same time, the device can accurately fix the rudder surface in the neutral position when the rudder surface lock and the outer clamping plate of the mounting bracket are not installed, saving a lot of time in the subsequent assembly of the stabilizer surface.

[0018] The following further describes the utility model in conjunction with embodiments. The following only describes a part of the embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0019] The following details the measuring device of the utility model with reference to the drawings:

[0020] According to the Figure 1 As shown, the measuring device is composed of six parts in total. Measuring body 1: There are two intersection holes on the mounting seat of the measuring body that are coordinated with the intersection joints of the product; Plug pin 2: The plug pin is used to connect and fix the measuring body and the product; Stop block 3: One end of the stop block is connected to the guide rod 4, and the other end has a boss matching the rudder surface lock body, which is used to position and fix the rudder surface lock body; Guide rod 4: The surface of the guide rod is provided with a groove and can move back and forth, which is used to push the stop block 3; Support 5: The support is provided with a hole matching the guide rod 4, which plays a guiding role for the guide rod 4; Nut 6, and the nut is provided with an internal thread matching the guide rod 4.

[0021] During measurement, the measuring body and the product are fixed through the plug pin 2. Adjust the nut 6 to change the extension amount of the guide rod 4, and move the rudder surface so that the boss of the stop block 3 enters the groove of the rudder surface lock body. The dimension from the intersection hole to the rudder surface lock body is obtained by measuring the distance between the rear end surface of the stop block 3 and the rear end surface of the support 5 plus the dimension from the rear end surface of the support to the intersection point.

[0022] Such as Figure 1As shown, this rudder surface lock body position measuring device has a simple structure. It adopts an integral structure, with one end fixed to the intersection joint of the product stabilizer surface, and the other end making the stopper fit with the rudder surface lock body through an adjusting guide rod. The distance between the two is measured through the transmission of a dimensional chain.
