Description

Technical Field

[0001] The present invention relates to a positioning and assembling device, in particular to a positioning and assembling device for installing parts in blind holes of aviation equipment, belonging to the technical field of design and manufacturing of production and maintenance process equipment for aviation equipment. Background Art

[0002] When assembling parts in blind holes of aviation products, manual marking and scribing are carried out first, then rubber rings are sleeved on the parts, and the parts are placed into the blind holes. Finally, the parts are manually pressed to make the parts assembled in place. There are the following deficiencies: 1. When manually marking and scribing, due to different visual angles of people, the scribing positions are different, resulting in scribing deviation; 2. When the gap between the assembled parts and the blind holes is small, after sleeving rubber rings on the parts, manually pressing the parts requires a force of nearly 1000N. During the manual pressing process, it will cause harm to the human arm; 3. The force application direction of the parts is uneven, which easily causes the parts to tilt and damage the sealing rubber rings. Summary of the Invention

The annular indicating disk is locked between the stepped protrusion of the guiding press-fitting frame and the middle section of the guiding press-fitting shaft.

[0009] Furthermore, fixing positioning holes are provided on both the water side plate and the vertical plate of the card slot type positioning disk, and the positioning card slot is provided on the vertical plate.

[0010] The preferred embodiment of the above solution is that the pressing and assembling component includes a pressing rod and a handle. The handle is vertically arranged on the power input end of the pressing rod, and the pressing rod abuts against the top of the guiding press-fitting component group through the end without the handle.

[0011] Furthermore, the pressing and assembling component further includes a bridge-type cantilever balance frame. A threaded through hole is provided on the horizontal side of the bridge-type cantilever balance frame, and a thread adapted to the threaded through hole is provided on the pressing rod. The pressing rod passes through the bridge-type cantilever balance frame through the thread and the threaded through hole, and the two power output ends of the bridge-type cantilever balance frame abut against the end face of the guiding press-fitting frame.

In this way, since the assembly position is determined by the positioning and guiding press-fitting assembly, when assembling the rubber ring into the blind hole, it is also completed through the positioning and guiding press-fitting assembly with the cooperation of the external force applied by the pressing and assembling assembly, changing the situation in the prior art where positioning requires manual scribing and assembly requires direct manual pressing by the operator. Therefore, not only the installation accuracy is significantly improved, but also the installation operation is relatively convenient. Brief Description of the Drawings
