Problems solved by technology

[0003] In order to avoid the impact of movement on the pyrotechnics and limit switch cables in the cover assembly, the relative positions of the pyrotechnics and limit switch cables, the cover, and the drive shaft of the device are fixed during design, resulting in the installation of the lock box of the cover assembly. And the installation of the primary locking station of the cover assembly is in an uncontrollable and unmeasurable state, which may prevent the device cover from being opened, resulting in the failure of the lunar sample collection mission

Embodiment 1

[0024] Embodiment 1: Referring to the accompanying drawings, a special tool for assembling a sealed and packaged device includes: a device installation base 1, a support rod 2, a cover body fixing support 3, a cover body pressing plate 4, a cover body installation rotary chuck 5, and Joint 6, torque wrench 7;

[0025] The device installation base 1 is used to connect and carry the support rod 2 and the sealing package device;

[0026] The lower end of the support rod 2 is connected to the installation base 1, and the upper end is connected to and supports the fixed support 3 of the cover;

[0027] The cover body fixing support 3 fixes the cover body assembly of the sealing and packaging device through the cover body pressing plate 4 thereon;

[0028] The cover is installed with a rotary chuck 5 for connecting and rotating the cover assembly of the sealed packaging device;

[0029] The adapter joint 6 is a torque transmission part between the torque wrench 7 and the rotary ch...

Embodiment 2

[0031] Embodiment 2: a method for assembling a hermetically sealed packaging device, which uses the special tool as in Embodiment 1, comprising the following steps:

[0032] A. Special tools for connecting the hermetic packaging device and hermetic packaging device assembly

[0033] Connect the installation base 1 of the device to the mounting flange of the sealing and packaging device through four M4 screws, install the cover assembly of the sealing and packaging device on the cover fixing support 3, and fix it through the cover pressure plate 4;

[0034] B. Hermetic packaging device lock box installation

[0035] Connect the cover mounting rotary chuck 5 with the cover assembly of the sealing package device, connect the adapter joint 6 with the cover mounting rotary chuck 5, connect the torque wrench 7 with the adapter joint 6, and rotate the torque wrench 7 to the sealing package At the installation station of the lock box of the device cover assembly, the torque of the to...

Abstract

The invention belongs to an assembly tool and particularly relates to assembly of a sealing packaging device. According to the technical scheme, a tool special for assembling the sealing packaging device and an assembling method are disclosed. The sealing packaging device comprises a device installation base (1), supporting rods (2), a cover fixing support (3), a cover pressing plate (4), a cover installation rotating chuck (5), a joint connector (6) and a torque wrench (7). The tool can be used for completing locking of a cover assembly of the sealing packaging device and installing of a one-time locking station, due to the measurement of relevant torque, whether unlocking spring tension and one-time locking friction force of the device meet design requirements or not can be judged, and it is ensured that a cover of the sealing packaging device can be reliably opened.

Description

technical field [0001] The invention belongs to an assembly tool, in particular to an assembly tool for a sealing and packaging device. Background technique [0002] The sealing and packaging device is one of the core devices of the Chang'e-5 probe. Its function is to undertake the lunar surface samples and deep drilling samples and automatically vacuum seal the samples. The sealed packaging device is a cylinder structure, including: a sealed container and a cover assembly. The open end of the sealed container is provided with a knife-edge structure, and an alloy ring is provided inside the cover assembly. When the cover assembly moves downward , the alloy ring is embedded in the knife-edge structure of the sealed container, and the stroke metal is extruded and sealed; before reaching the surface of the moon, the sealing and packaging device is in a locking position, and the transmission shaft of the sealing and packaging device drives the cover body assembly to move during ...
