Description

A can dismantle closing device for narrow and small space

Technical Field

The application relates to the field of aircraft component assembly in the aviation manufacturing industry, in particular to a detachable pressing device for a narrow space.

Background

The hold-down device is most often used in aircraft assembly and is typically fixedly mounted for product stability. However, the detachable pressing device used in the narrow space is few, and is generally pressed by a simple pressing screw, but the mode can only be in point or line contact with a product, and cannot be provided with a product profile, so that the product is often crushed due to incompact pressing or point-line contact, and in order to solve the actual problem in the field, the detachable adjustable pressing device used in the narrow space needs to be designed.

Disclosure of Invention

In order to solve the problem that the product is not pressed down to reality or point contact crushing, the utility model aims to provide a detachable closing device for narrow and small space, this structure is quick detachable connection structure, and the structure of connecting does not break away from with closing device in the use, can compress tightly the product profile fast, can lift off fast after the use, does not influence original structure and subsequent handling.

In order to achieve the above purpose, the following technical scheme is adopted to realize the purpose:

the utility model provides a can dismantle closing device for narrow and small space, including the snap ring, compression screw, swivel nut, the briquetting, the baffle, the bolt, the snap ring stretches into in the fixed knot structure of product location usefulness, and tighten up on fixed knot constructs with compression screw, the snap ring center be equipped with swivel nut's screw rod complex screw thread, swivel nut's lower part is the polished rod, open at polished rod bottom center have with bolt complex screw hole, the briquetting is connected with the partial bolt tightening of swivel nut polished rod, the briquetting center is equipped with the counter bore, its aperture is greater than the polished rod diameter, the polished rod length is good at to the aperture degree of depth, it can drive the briquetting motion of below to rotate swivel nut, the briquetting side is equipped with the baffle, it can not rotate only to have restricted the briquetting to reciprocate, briquetting below profile and product laminating completely compress tightly.

Furthermore, the upper half part of the rotating nut is a screw rod, the middle part of the rotating nut is a knurled nut, and the lower half part of the rotating nut is a polished rod.

Furthermore, the baffle is a square plate, and the length of the baffle does not exceed the height of the snap ring.

Furthermore, the molded surface below the pressing block is consistent with the molded surface of the product.

The detachable pressing device has the advantages that the detachable pressing device is small in size and can be applied to narrow spaces; the device can be freely and quickly installed on the original positioning structure to effectively compress the molded surface of the product; when not in use, the utility model can be quickly disassembled, and the original structure is not damaged, and the subsequent procedures of the product are not affected.

The present application is described in further detail below with reference to the accompanying drawings of embodiments.

FIG. 2 is a schematic view of the detachable device when adjustable.

FIG. 3 is a schematic view of the assembled relationship of the detachable device.

Fig. 4 is a schematic view of the fixture structure for positioning the product.

The numbering in the figures illustrates: 1 snap ring, 2 swivel nuts, 3, pressing block, 4 baffle plates, 5 compression screws and 6 bolts.

Detailed Description

Referring to the attached drawings 1-4, a detachable pressing device for a narrow space comprises a clamping ring 1, a pressing screw 5, a rotating nut 2, a pressing block 3, a baffle 4 and a bolt 6, wherein the clamping ring 1 extends into a fixing structure for positioning a product, and is screwed on the fixed structure by a compression screw 5, the center of the snap ring 1 is provided with a thread matched with the screw rod of the rotating nut 2, the lower part of the rotating nut 2 is a polished rod, the center of the bottom of the polished rod is provided with a threaded hole matched with a bolt 6, the press block 3 is connected with the polished rod part of the rotating nut 2 by the bolt 6 in a compression way, the center of the press block 3 is provided with a counter bore, the aperture of the small hole is larger than the diameter of the polished rod, the depth of the small hole is longer than the length of the polished rod, the rotary nut 2 is rotated to drive the pressing block 3 below to move, the side surface of the pressing block 3 is provided with the baffle 4, the pressing block 3 is limited to move only up and down and can not rotate, and the molded surface below the pressing block 3 is completely attached to and pressed with a product.

Further, the upper half part of the rotating nut 2 is a screw rod, the middle part is a knurled nut, and the lower half part is a polished rod.

Further, the baffle 4 is a square plate, and the length of the baffle does not exceed the height of the snap ring 1.

Furthermore, the molded surface below the pressing block 3 is consistent with the molded surface of the product.

The application has solved present closing device's that needs dismantle design problem in narrow and small space effectively, and need not carry out any change to original structure, does not have any influence to the subsequent handling, has improved production efficiency, and the structure is succinct simultaneously, and the equal parameterization of primary dimension designs, and the snap ring still can carry out the size according to original fixed knot structure and match, and application range is extensive, uses and maintains the convenience, but wide application in aircraft part production, subassembly assembly.
