Problems solved by technology

[0008] However, this system suffers from the disadvantage that the linkage 440 is subjected to considerable mechanical stress and wears out quickly
Said tool attachments for installing keylock inserts are thus unreliable and the linkage often requires replacement or repair

Embodiment Construction

[0031] The power head 100 is equipped with the tool attachment 100 of the present invention for installing keyed inserts, hereinafter referred to Figures 4 to 6 describe.

[0032] The power head 100 is an angled drive for fastening all types of belts or the like. The powerhead 100 is powered through a joint 102 by a pneumatic power source (not shown). It has an elongated body 103 containing a mechanism for using powered air pressure in a manner to transmit an output tightening (or loosening) torque. An air feed connection 102 is connected to a first end 104 of the powerhead 100 . At the other end 106 of the power head (the end forming a right angle), the power head 100 has a joint interface 108 that can be used to fasten and drive a fastening connector or some other tool attachment adapted to be mounted on the power head 100 .

[0033] Finally, the power head 100 has a trigger mechanism (lever 110 ) that can be used to put the power head 100 under air pressure and make fas...

Abstract

In order to place a bushing (300) with a pin (320), the equipment of the invention can be mounted on a screwing tool (100) and connected to a pneumatic supply. The equipment comprises a screwing-torque transmission device (14, 52) for screwing the bushing and, within a casing (12), a pin hammering device (16) for crimping the pin onto the bushing when a crimping pressure is applied thereto by thepneumatic supply. The hammering device (16) comprises a plurality of plates (18A, 18B, 18C) substantially perpendicular to the screwing axis. The crimping pressure violently applied on the plates inside the casing (12) drives the pin hammering device and results in the crimping thereof. The equipment does not include mobile mechanical parts and has a high reliability. The invention also relates to a kit including this type of equipment with a screwing tool.

Description

technical field [0001] The present invention relates to the field of tool accessories for installing keying inserts or "keying bushings". Background technique [0002] Such a keylock insert 300 is shown in figure 1 and 2 middle. The key lock insert 300 includes: an insert body 310 or "bushing body" which is installed by screwing in; and one or more keys 320 (four are shown in the illustrated example) which are crimped during installation to prevent any plugs from coming loose. The key is crimped by being struck axially (in the axial direction of the body of the insert, as indicated by arrow A), so that the key penetrates under force between the insert and the hole in which it is screwed. between. [0003] To install the keylock insert, an installation tool attachment fitted to the power head is often used. An example of such a tool attachment 400 is at image 3 , where it is shown assembled on a pistol-shaped powerhead 500. [0004] To enable the insert to be screwed...
