Description

Technical Field

[0001] The invention belongs to the field of thread assembly, and in particular relates to a thread tightening device for a guidance cabin. Background Art

[0002] At present, when threading the nose cone and navigation cabin of a certain product, the material performance characteristics of the two parts are quite different. The high-density alloy parts are weakly magnetic, heavy, hard, and have strong cutting effects; the hard aluminum alloy parts are large, heavy, and have low hardness. The connection method between the two is a large-size threaded connection with secondary precision. Usually, manual screwing is used, which is time-consuming and laborious, and is particularly prone to thread locking, resulting in high rework costs, low assembly efficiency, poor process economy, and certain operational safety hazards.

Insert the base 1 from the upper end of workpiece a7 downward, so that the inner arc surface of the base 1 fits on the outer arc surface of workpiece b8. Apply slight downward force until the two arc surfaces are completely matched and fixed stably.

[0009] Screw the bracket frame 2 clockwise until its notch is lower than the bottom surface of the workpiece a7, and insert the two support plates 10 into the grooves on both sides of the bracket frame 2, so that the support plates 10 are fixed on the bracket frame 2;

[0010] Screw it upward until the upper end surface of the support plate 10 contacts the lower end surface of the workpiece a7, continue to rotate the support seat 2 upward to lift the head cone of the workpiece a7, and when the pin holes on both sides are aligned with the process holes of the workpiece a7, screw the support frame 2 clockwise until it is tightened to the root of the thread of the workpiece b8, pull out the fixed support plate 10, and then take the tooling out as a whole from bottom to top along the outer end of the workpiece a7.

[0013] Among them, a gasket 12 is bonded to the inner arc surface of the base 1, and is attached to the outer arc surface of the workpiece b8 through the gasket 12.

[0014] When the pin holes on both sides of the bracket frame are aligned with the process holes of the workpiece a7, the screwing is stopped and the pin 11 is inserted to prevent the workpiece a7 and the bracket frame 10 from moving relative to each other when screwing.

[0015] The bracket frame 2 and the support plate 10 are provided with four through holes, each of which is provided with a pin 9 to prevent the bracket 2 and the support plate 10 from sliding relative to each other.
