Description

Technical Field

[0001] This utility model belongs to the field of fastener manufacturing technology, specifically relating to an expansion bolt inverted and constricted end mechanism. Background Technology

[0002] Self-locking bolts require a shrinking process for their expansion sleeves during production. There is an existing shrinking device for nuts with the authorization announcement number CN201979016U, which has a forward-facing shrinking mechanism. The guide plate is fully lifted upwards before the nut is inserted, which takes a long time and results in low production efficiency. Therefore, it is very important to obtain an inverted shrinking mechanism for expansion bolts. Utility Model Content

[0003] To solve at least one of the above-mentioned technical problems, this utility model provides an expansion bolt inverted and constricted end mechanism, comprising:

[0004] The moving component has a working chamber, and a drive unit is arranged on the inner wall of the working chamber;

[0005] The mounting section, at least partially disposed in the working chamber, is used to mount the workpiece to be processed;

[0006] A necking assembly is at least partially disposed in the working chamber. The necking assembly includes at least two necking bodies. The outer wall of the necking body is at least partially provided with a driven part that cooperates with the driving part. The necking bodies are at least partially located on both sides of the workpiece to be processed.

[0007] The upward moving drive part of the moving component abuts against the driven part to cause the narrowing body to move inward and act on the workpiece to achieve narrowing.

[0008] Through the above technical solution, the inverted constriction mechanism of this utility model allows for quick nut installation, saving costs and improving production efficiency.

[0009] It also includes a support plate, the bottom surface of which is fixedly connected to a mounting component via a pressure sensor, and the bottom surface of the mounting component has a mounting slot to form the mounting part.

[0010] The pressure sensor setting enables monitoring. Once the pressure sensor detects that the closing point has reached the set pressure in real time, the operation can be stopped, making it easy to determine whether the closing product is qualified.

[0011] It also includes a connector with at least one moving channel through which a support plate passes, and the constriction assembly is mounted on the connector located below the support plate. It also includes a drive motor, the output shaft of which is connected to a lead screw, which cooperates with the support plate to move the connector up and down.

[0012] An adjusting cylinder is fixed on a support plate located within the connector, and the lead screw is at least partially located within the adjusting cylinder. A transmission cylinder connects the lead screw and the adjusting cylinder.

[0013] The driving part includes a first inclined surface extending downwards towards the center of the working chamber, and the driven part includes a second inclined surface that mates with the first inclined surface. A conical groove is provided on the inner wall of the working chamber, the width of which decreases sequentially from top to bottom to form the first inclined surface. The constriction assembly is a conical body that mates with the conical groove, and the side surface of the conical body forms the second inclined surface.

[0014] A guide structure is connected between the mounting component and the constricted body. The guide structure includes mutually cooperating guide protrusions and guide grooves formed at the bottom of the mounting component and the top of the constricted body.

[0015] Compared with the prior art, the advantages of this utility model are: the utility model has a simple structure. By driving the motor to control the action of the lead screw, the connecting parts are controlled to move up and down to realize the up and down movement of the moving components, and the shrinking parts are controlled to tighten inward to realize the shrinking of the bolt.
