Description

Technical Field

[0001] This utility model relates to the technical field of riveting tools, specifically a controllable manual riveting tool for riveting rivets. Background Technology

[0002] The international situation is constantly changing. In order to safeguard national defense and security, every country has accelerated the pace of national defense construction. As an important air superiority tool, my country has also continuously developed many new aircraft models as needed, which have put forward higher requirements for comprehensive performance such as stealth, speed, load capacity and maneuverability. At the same time, new requirements have been put forward for the stability of the aircraft connection process and the diversity of the structure.

[0003] As aircraft models evolve, new requirements arise for the use of specialized connectors on different materials. Aircraft connection solutions must keep pace with these advancements. In the process of product updates and iterations, ordinary bolts, screws, and rivets are gradually being replaced by higher-strength and more reliable connection methods, such as the various types of pull studs currently in use. These pull studs require a specialized riveting gun for installation. A rotational torque is applied to the core rod, causing it to rotate and pull the component outwards. After the tube contacts the sandwich panel, it gradually deforms, forming a bulge. Continued rotational torque causes the core rod to break after a certain degree of deformation, completing the riveting installation. However, when using these pull studs in confined spaces, it is impossible to install them using a riveting gun. This reduces the product's usability and increases installation costs. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a controllable pull-pin manual riveting tool that enables the installation of controllable pull-pin products in narrow spaces and complex environments.

[0005] The purpose of this utility model is achieved through the following technical solution: a controllable manual riveting tool for pull pins, the tool including a connector and a back cover, the inner side of the connector is provided with a groove for placing a drive nut and a drive sleeve, the drive sleeve is provided with a through hole, and the central axis of the drive nut placed on the inner side of the connector and the hole of the drive sleeve are on the same straight line, the back cover is sleeved on the outer side of the drive sleeve and is connected to the connector, the drive sleeve is used to transmit torque and tighten the core rod of pull pin products.

[0006] The drive sleeve includes a rotating part and a baffle part. The outer diameter of the baffle part is larger than the outer diameter of the rotating part. The rear cover and the spring are both sleeved on the outside of the rotating part, and the spring is disposed between the rear cover and the baffle part. The spring is used to limit the drive sleeve and keep the drive sleeve in the lower limit position.

[0007] The upper outer side of the rotating part is designed in a hexagonal or dodecagonal shape to facilitate wrench locking.

[0008] The bottom inner side of the rear cover is screwed to the top outer side of the connector. The rear cover is used to fix the drive sleeve, spring and connector.

[0009] It also includes a pull pin, the top of which is provided with a core rod, which passes through the center of the drive nut and the hole of the drive sleeve in sequence.

[0010] The drive nut is placed below the drive sleeve. The connector is used to hold the drive nut of the pin-type product and, in conjunction with the torsion of the drive sleeve, enables the installation of the product.

[0011] The outer diameter of the pull pin is larger than the outer diameter of the core rod, which makes it easier for the driving nut to squeeze the end face of the pull pin, so that the top of the pull pin is deformed and thickened, forming a pull pin head at the same time.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model enables manual riveting of controllable tapped nail products, improving product usability.

[0014] 2. This utility model enables the installation of controllable tapped pin products in narrow spaces and complex environments. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] In one embodiment of this application:

[0030] like Figures 1 to 11 As shown, a controllable pull pin manual riveting tool is provided. The tool includes a connector 4 and a back cover 2. The inner side of the connector 4 is provided with a groove for placing a drive nut and a drive sleeve 1. The drive sleeve 1 is provided with a through hole. The central axis of the drive nut placed on the inner side of the connector 4 and the hole of the drive sleeve 1 are on the same straight line. The back cover 2 is sleeved on the outer side of the drive sleeve 1 and is connected to the connector 4.

[0031] The drive sleeve 1 includes a rotating part 8 and a baffle part 9. The outer diameter of the baffle part 9 is larger than the outer diameter of the rotating part 8.
