Abstract

The invention discloses an installation device for a long shaft of a ventilating nozzle. The installation device for the long shaft of the ventilating nozzle is characterized in that the installation device comprises a base; a diagonal plane is arranged on one side of the upper portion of the base, and the included angle between the diagonal plane and a vertical line is equal to the included angle between the long shaft of the ventilating nozzle and the cover surface of a ventilating cover of the ventilating nozzle. An upper vertical blind hole is formed in the diagonal plane. A limiting block is arranged at the hole bottom of the upper vertical blind hole. A supporting block used or supporting the ventilating cover is arranged on the portion, below the orifice of the upper vertical blind hole, of the diagonal plane. A pressing head is arranged at the top of the base. A hydraulic machine is arranged above the pressing head. An ejector rod is fixed below the pressing head. The diameter of the ejector rod is matched with that of the upper vertical blind hole. A lower vertical blind hole is formed in the center of the lower end of the ejector rod. The diameter of the lower vertical blind hole is matched with that of the installed long shaft. By assembling the long shaft and the ventilating cover through the installation device, the product quality can be improved, and the production cost is reduced. The installation device is suitable for assembly of the long shaft and the ventilating cover on the ventilating nozzle in a helicopter cabin.

Description

The long shaft mounting device of ventilation mouths

Technical field

The present invention relates to a kind of frock. Specifically, it is long shaft mounting device major axis being installed on the ventilation cover of ventilation mouths, it is applicable to the major axis on the ventilation mouths in vertisplane cabin and the assembling between ventilation cover.

Background technology

Manufacture field at vertisplane all to know, for keeping the air in cabin good, ventilation mouths is all installed in the cabin of vertisplane. Ventilation mouths includes the ventilation cover for regulating air quantity, and ventilation cover is provided with major axis. Its major axis one end is the center that tight shape is inserted and secured on ventilation cover, and makes to be formed between the axis of major axis and the lid face of ventilation cover a bigger inclination angle. At present, the major axis on ventilation mouths is installed on ventilation cover adopt method be manual operations, namely one personal two hand steered live ventilation covers, and make as requested ventilation cover lid face keep described in inclination angle. Another person pinches major axis on the other hand, and another holds the upper end that hammer strikes major axis too hard, makes the center of the lower end insertion ventilation cover of major axis, realizes the assembling between major axis and ventilation cover with this. Owing to the assembling between major axis and ventilation cover relies on manual operations completely, the angle between major axis and ventilation cover lid face is difficult to control, and product consistence is poor so that quality product is poor. Again owing to the assembling between major axis and ventilation cover relies on manual operations completely, the degree of depth of major axis lower end insertion ventilation cover is restive, although there is lower convex platform at the lower surface center of ventilation cover, assembling process still can occur the lower end of major axis pass the situation of ventilation cover, make scrap rate higher, thus increase production cost.

Summary of the invention

The problem to be solved in the present invention is to provide a kind of long shaft mounting device of ventilation mouths. Adopt the assembling of this kind of device to carry out between major axis and ventilation cover, can improve the quality of products, reduce production cost.

The problems referred to above that the present invention to be solved are realized by following technical scheme:

It is comprise base that the ventilation mouths major axis of the present invention installs device characteristic, and there is diagonal plane the side, top of described base, and the angle of diagonal plane and vertically line equals the angle between the major axis of ventilation mouths and its ventilation cover lid face. Erect to blind hole on described diagonal plane has, on erect to limited location block at the bottom of the hole of blind hole. On erect the tray having on the diagonal plane below blind hole aperture for holding ventilation cover. Base top has pressure head, has hydropress above pressure head. Be fixed with push rod below pressure head, the diameter of described push rod and on erect to blind hole suitable. Push rod lower center erects to blind hole under having, lower erect to the diameter of blind hole suitable with mounted major diameter.

Further improvement of the present invention scheme is, described tray is bolted on described diagonal plane by two the 2nd, and the recessed arc-shaped side of the top of tray for ease of coordinating with ventilation cover.

Wherein, described two the 2nd bolts be in same level and and on erect and be arranged symmetrically between blind hole.

Further improvement of the present invention scheme is, described tray is fan-shaped, and its inner circle is upward.

The further improvement scheme of the present invention is, described base is cylindrical.

As can be seen from the above scheme, owing to the long shaft mounting device of ventilation mouths of the present invention comprises base, there is diagonal plane the side, top of described base, and the angle of diagonal plane and vertically line equals the angle between the major axis of ventilation mouths and its ventilation cover lid face. Erect to blind hole on described diagonal plane has, on erect to limited location block at the bottom of the hole of blind hole. On erect the tray having on the diagonal plane below blind hole aperture for holding ventilation cover. Base top has pressure head, has hydropress above pressure head. Be fixed with push rod below pressure head, the diameter of described push rod and on erect to blind hole suitable; Push rod lower center erects to blind hole under having, lower erect to the diameter of blind hole suitable with mounted major diameter. During assembling, hydropress can be manipulated by automation control appliance again, and by pressure head by next for the push rod pressure distance set in advance, make the optimum depth needed in the lower end insertion ventilation cover of major axis. Compared with the manual manipulation method in background technology, the degree of depth of the lower end insertion ventilation cover of major axis easily controls, and avoids the situation generation that the lower end of major axis passes ventilation cover, thus reduces scrap rate and production cost. Again owing to the side, top of base is processed with diagonal plane, the angle of diagonal plane and vertically line equals the angle between the major axis of ventilation mouths and ventilation cover lid face, angle between major axis and ventilation cover lid face sets in advance, angle between major axis and ventilation cover lid face easily controls, making the consistence of product good, quality product is higher.
