Abstract

The utility model belongs to the technical field of the riveting assembly, especially, relate to a take double-handle mounting tool of snap ring screw thread inserts. Threaded inserts with snap rings are typically installed manually or assisted with universal bolts with matching threads. But the problems that the bolt is inconvenient to withdraw, the mounting quality of the insert is unstable and the like can occur. The utility model comprises an upper handle, a lower handle and a screw rod, wherein the fixed end of the end part of the upper handle is sleeved with the top end of the screw rod so as to prevent the screw rod from rotating, the rotating end of the end part of the lower handle is in threaded connection with the screw rod, and a threaded insert with a snap ring is in threaded connection with the screw rod at the lower side of the lower handle; the swivel head has a structure that engages the snap ring to enable rotation of the threaded insert with the snap ring into the preformed hole. The mounting efficiency and the mounting quality of the insert are improved, and the possibility of the problems of unilateral clearance and the like after the insert is mounted is eliminated.

Description

Double-handle installation tool with snap ring threaded insert

Technical Field

The utility model belongs to the technical field of the riveting assembly, especially, relate to a take double-handle mounting tool of snap ring screw thread inserts.

Background

As shown in fig. 1, the snap ring threaded insert includes a shank with internal and external threads and a head snap ring. In airplane riveting assembly, the threaded insert with the snap ring has a small application range, does not have a special installation tool, and is generally installed manually or is installed in an auxiliary mode by using a general bolt with matched threads. But the problems that the bolt is inconvenient to withdraw, the mounting quality of the insert is unstable and the like can occur.

SUMMERY OF THE UTILITY MODEL

Limitation to current band clamp ring screw thread inserts installation, the utility model provides a double-handle mounting tool to band clamp ring screw thread inserts.

The technical scheme of the utility model: the tool comprises an upper handle, a lower handle and a screw rod, wherein a fixed end at the end part of the upper handle is sleeved with the top end of the screw rod so as to prevent the screw rod from rotating, a rotating end at the end part of the lower handle is in threaded connection with the screw rod, and the threaded insert with the snap ring is in threaded connection with the screw rod at the lower side of the lower handle; the swivel head has a structure that engages the snap ring to enable rotation of the threaded insert with snap ring into the preformed hole.

Advantageously, the screw has a polygonal end, the fixed end having a polygonal hole combined with the polygonal end.

Advantageously, the polygonal aperture is a rectangular aperture.

Advantageously, the length of the screw is slightly greater than the length of the threaded insert with the clasp.

Advantageously, the external diameter of the screw is smaller than the internal diameter of the preformed hole.

Advantageously, the upper handle and the lower handle have a certain length.

The utility model has the advantages that: the mounting efficiency and the mounting quality of the insert are improved, and the possibility of the problems of unilateral clearance and the like after the insert is mounted is eliminated.

Drawings

The illustrative examples, as well as a preferred mode of use, further objectives, and descriptions thereof, will best be understood by reference to the following detailed description of an example of the present invention when read in conjunction with the accompanying drawings, wherein:

FIG. 1 is a schematic structural view of a threaded insert with a snap ring;

fig. 2 is a schematic structural view of a two-handle installation tool.

Wherein, 1-upper handle, 2-fixed end, 3-rectangular hole, 4-lower handle, 5-screw rod, 6-rotary end

Detailed Description

The disclosed examples will be described more fully with reference to the accompanying drawings, in which some (but not all) of the disclosed examples are shown. Indeed, many different examples may be described and should not be construed as limited to the examples set forth herein. Rather, these examples are described so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Referring to fig. 1, a two-handle installation tool for a threaded insert with a snap ring includes an upper handle 1, a lower handle 4, and a threaded rod 5, where the upper handle 1 has a fixed end 2 and the lower handle 4 has a rotating end 6. The upper handle 1 and the fixed end head 2 are integrated, the lower handle 4 and the rotating end head 6 are integrated, the length of the screw rod 5 is determined by the length of the mounted insert, and the screw rod 5 is matched with the internal thread of the insert.

During the use, will rotate end 6 and revolve to 2 lower extremes of the fixed end of top of screw rod 5, will follow afterwards according to the inserts and the buckle of waiting to install and revolve to 6 lower extremes of rotatory end to insert screw rod 5 prefabricated downthehole 2-3 knot degree of depth, go up handle 1 and play the fixed action, rotatory lower handle 4 is gently screwed in inserts and snap ring in prefabricated downthehole, waits that snap ring and prefabricated hole parallel and level accomplish the installation promptly.

Different examples of the systems, devices, and methods disclosed herein include various components, features, and functions. It should be understood that the various examples of the systems, devices, and methods disclosed herein may include any of the components, features, and functions of any of the other examples of the systems, devices, and methods disclosed herein in any combination or any sub-combination, and all such possibilities are intended to fall within the scope of the present invention.

The description of the different advantageous arrangements has been presented for purposes of illustration and description, but is not intended to be exhaustive or limited to the examples in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. Additionally, the different advantageous examples may describe different advantages as compared to other advantageous examples. The example or examples selected are chosen and described in order to best explain the principles of the examples, the practical application, and to enable others of ordinary skill in the art to understand the disclosure for various examples with various modifications as are suited to the particular use contemplated.
