Description

Technical Field

[0001] This utility model relates to the field of testing tooling technology, specifically a special angle testing tooling for aerospace servo mechanisms. Background Technology

[0002] A certain type of aerospace servo mechanism is characterized by its precise structure, compact size, and high sensitivity. However, when assembling and adjusting the angles of the inner and outer frames, it is impossible to use protractors or other measuring equipment to measure the angles. The existing technology uses a coordinate measuring machine (CMM) to measure the angles, which is very inconvenient due to limitations in space and personnel. Moreover, this angle needs to be measured while being adjusted, and the relevant parts are too small, making installation and disassembly difficult due to space constraints. While a CMM can be used to measure the angles during the research and development stage when the production quantity is small, it will not be suitable after mass production, and the measurement method will become a bottleneck restricting the production progress.

[0003] To address the aforementioned issues, we have made innovative designs based on the existing angle detection fixture structure for aerospace servo mechanisms. Utility Model Content

[0004] The purpose of this utility model is to provide a special angle detection tooling for aerospace servo mechanisms, so as to solve the problem mentioned in the background art that existing devices cannot use protractors or other detection equipment to detect angles when assembling and debugging the inner and outer frame angles.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a special angle detection fixture for aerospace servo mechanisms, comprising a fixed base, an aerospace servo mechanism, a servo mechanism mirror mount, a special pad, a positioning hole, and a miniature digital display inclinometer; the aerospace servo mechanism is fixedly installed on the top of the fixed base, and a servo mechanism mirror mount is fixedly installed on the upper end of the aerospace servo mechanism; the special pad is disposed on the outside of the servo mechanism mirror mount, and a positioning hole is opened on the inner side of the special pad; and a miniature digital display inclinometer is connected to the outside of the special pad.

[0006] Preferably, a fixing plate is provided on the outer side of the special pad, and a through groove is provided on the inner side of the fixing plate.

[0007] Preferably, an internal hexagon screw passes through the inner side of the through groove, and the tail end of the internal hexagon screw is threaded into the inner side of the positioning hole.

[0008] Preferably, the fixing plate and the special pad are distributed in a front-to-back correspondence about the midpoint of the servo mechanism mirror mount.

[0009] Preferably, the special pad and the micro digital display inclinometer form a magnetic attraction structure.

[0010] Compared with the prior art, the beneficial effect of this utility model is that the special angle detection fixture for aerospace servo mechanisms is:

[0011] Because the aerospace servo mechanism is small and compact, it is difficult to measure using an angle ruler or a micro digital inclinometer. Therefore, this invention designs a special pad, a standard pad, a fixing plate, and hex socket screws to work with a micro digital inclinometer to form a special angle detection fixture. This fixture is compact in appearance, and the inclinometer it is paired with has high sensitivity and accuracy that meets the testing standards. The micro digital inclinometer is placed on the test surface of the special or standard pad and clamped to the test part of the aerospace servo mechanism to perform angle detection, thus solving the problem of difficult angle measurement for this product.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-6This utility model provides a technical solution: a special angle detection fixture for aerospace servo mechanisms, including: a fixed base 1, an aerospace servo mechanism 2, a servo mechanism mirror base 3, a special pad 4, a positioning hole 5, and a miniature digital display inclinometer 6; the aerospace servo mechanism 2 is fixedly installed on the top of the fixed base 1, and the servo mechanism mirror base 3 is fixedly installed on the upper end of the aerospace servo mechanism 2; the special pad 4 is located on the outside of the servo mechanism mirror base 3, and the positioning hole 5 is opened on the inner side of the special pad 4; and the miniature digital display inclinometer 6 is connected to the outside of the special pad 4.

[0021] A fixing plate 7 is provided on the outer side of the special pad 4, and a through groove 8 is provided on the inner side of the fixing plate 7; an internal hexagon screw 9 passes through the inner side of the through groove 8, and the tail end of the internal hexagon screw 9 is threaded to the inner side of the positioning hole 5; the fixing plate 7 and the special pad 4 are distributed in a front-to-back correspondence about the midpoint of the servo mechanism mirror base 3; the special pad 4 and the micro digital display inclinometer 6 form a magnetic attraction structure;

[0022] A special angle detection fixture for aerospace servo mechanisms consists of two sets of fixtures: an inner frame angle detection fixture and an outer frame angle detection fixture. It includes a miniature digital inclinometer 6, a special pad 4, a fixed base 1, a fixing plate 7, and hex socket screws 9. When the outer frame rotates clockwise or counterclockwise, the aerospace servo mechanism 2 is placed on the fixed base 1. The special pad 4 is clamped onto the servo mechanism's mirror base 3 using the fixing plate 7 and hex socket screws 9. The miniature digital inclinometer 6 is then attached to the detection table of the special pad 4 for measurement. When measuring the pitch angle of the inner frame of the aerospace servo mechanism 2, the aerospace servo mechanism 2 is placed on the fixed base 1. The special pad 4 is placed on the servo mechanism's mirror base 3 and clamped. The miniature digital inclinometer 6 is then attached to the detection table of the special pad 4 for measurement. The aerospace servo mechanism 2 features a precise, compact structure and high sensitivity. When measuring the pitch angle of the inner frame and the clockwise / counterclockwise rotation angle of the outer frame, it is difficult to... Using protractors and other measuring equipment cannot guarantee the required pitch angle of the inner frame to be no less than ±10° and no more than ±10.5°, and the clockwise and counterclockwise rotation angle of the outer frame to be ±20°. This design provides a dedicated angle measuring fixture for the aerospace servo mechanism 2, which can quickly and accurately measure angles, solving the problem of angle control difficulties during assembly and manufacturing, greatly reducing cost budget and assembly difficulty, and ensuring product quality and schedule. Compared with the original solution of using three-coordinate measuring, the use of this angle measuring fixture makes angle measurement of this product more convenient, allowing measurement to be performed while repairing. The original repair, adjustment and measurement of one set of aerospace servo mechanism 2 required an average of 0.5 days, while the repair, adjustment and measurement of one set requires an average of about 0.1 days after using this dedicated angle measuring fixture, greatly reducing the time. Furthermore, the use of this dedicated angle measuring fixture is not limited by site or equipment, and can be performed anytime and anywhere, laying a solid foundation for mass production.
