Description
技术领域technical field
本发明属于航天器装配检测技术领域，具体涉及解锁结构中导轨间距的测量工装，以定性地对解锁机构导向装置进行快速检测。The invention belongs to the technical field of spacecraft assembly detection, and in particular relates to a tool for measuring the distance between guide rails in an unlocking structure, so as to qualitatively and quickly detect the guiding device of the unlocking mechanism.
背景技术Background technique
某型号月面巡视探测器与软着陆探测器分离过程中的解锁机构是其软着陆后两器分离的关键部件。该解锁机构能否正确、顺利地安装到位，关系着某型号月面巡视探测器软着陆后能否顺利进行两器分离，因此，是总装工作的一个关键环节。为此，该连接解锁机构的装配尺寸有非常高的要求，具体要求两内侧导向装置(即导轨之间)距离的达到严格698mm±0.4mm的测量要求，但是在高空复杂工况上进行测量，给测量的实施带了很大的难度。The unlocking mechanism in the separation process of a certain type of lunar surface inspection probe and soft landing probe is the key component for the separation of the two after the soft landing. Whether the unlocking mechanism can be installed correctly and smoothly is related to whether a certain type of lunar patrol detector can be separated smoothly after a soft landing. Therefore, it is a key link in the final assembly work. For this reason, the assembly size of the connection and unlocking mechanism has very high requirements. Specifically, the distance between the two inner guides (that is, between the guide rails) is required to meet the strict measurement requirements of 698mm±0.4mm. It brings great difficulty to the implementation of measurement.
通常，该锁机构导向装置的安装尺寸公差要求为698mm±0.4mm，同时具有上公差和下公差的安装要求，698mm具有大尺寸的特点，现有总装用的测量工具如游标卡尺无法满足测量要求。此外，该解锁机构导向装置安装在着陆探测器的顶板上，因此测量需要在高空作业，由于高空作业平台的局限性，只能满足一个操作人进行操作，且由于器表突出物的影响，很难满足一个人在高空作业平台的操作需求，同时，导向装置长1432mm，若测量采用在导向装置选择点的方式，则无法实现整根导向装置的位置公差。Usually, the installation dimensional tolerance requirement of the guide device of the lock mechanism is 698mm±0.4mm, with both upper and lower tolerance installation requirements, 698mm has the characteristics of a large size, and the existing measuring tools such as vernier calipers for general assembly cannot meet the measurement requirements. In addition, the guide device of the unlocking mechanism is installed on the top plate of the landing probe, so the measurement needs to be performed at high altitudes. Due to the limitations of the aerial work platform, only one operator can operate, and due to the influence of the protruding objects on the surface, it is very difficult to It is difficult to meet the operation needs of one person on the aerial work platform. At the same time, the guide device is 1432mm long. If the measurement is made at the selected point of the guide device, the position tolerance of the entire guide device cannot be achieved.
采用普通游标卡尺测量有如下弊端：The use of ordinary vernier caliper measurement has the following disadvantages:
1)测量工况复杂，测量方法无法实现全尺寸测量；1) The measurement conditions are complex, and the measurement method cannot achieve full-scale measurement;
2)测量工具过重，影响测量精度；2) The measuring tool is too heavy, which affects the measurement accuracy;
3)超大跨度的大尺寸测量要求，高空作业环境恶劣下，影响测量精度；3) The large-scale measurement requirements of super-large spans, and the harsh environment of high-altitude operations will affect the measurement accuracy;
针对上述总装问题，本发明需要提供一种能够进行高空作业，实现月面巡视探测器与软着陆探测器分离过程中的解锁机构的导轨间距精确、可行测量的工装。In view of the above-mentioned general assembly problem, the present invention needs to provide a tool capable of carrying out high-altitude operations and realizing accurate and feasible measurement of the guide rail spacing of the unlocking mechanism during the separation process of the lunar patrol detector and the soft landing detector.
