Abstract
A hydraulic installation tool for installing fasteners is provided, that includes a housing having a first portion adapted to receive a drawbar and a second portion adapted to receive a piston, a gland and a retaining ring. A generally L-shaped drawbar is disposed in the first portion of the housing and a piston, a gland and a retaining ring is disposed in the second portion of the housing. The hydraulic installation tool is useful in securing lockbolt or swage type fasteners.
Claims20
A hydraulic installation tool for installing fasteners comprising:
- (a) a housing having a first portion adapted to receive a drawbar and a second portion adapted to receive a piston, a gland and a retaining ring;
- (b) the drawbar having a general L-shape, a through bore and a bore, a portion of the drawbar being slidably disposed within the first portion of the housing;
- (c) the piston having a threaded bore, a portion of the piston being slidably disposed within the second portion of the housing;
- (d) the gland having a first bore adapted to receive a portion of the piston and a threaded second bore, the gland disposed within the second portion of the housing with a portion of the piston passing through the first bore of the gland;
- (e) the retaining ring having a bore, the retaining ring disposed within the second portion of the housing and threadedly engaging the housing with a portion of the piston passing through the bore of the retaining ring;
- (f) a threaded first screw passing through the bore of the drawbar and threadedly engaging the threaded bore of the piston;
- and
- (g) a threaded second screw passing through the bore of the retaining ring and threadedly engaging the threaded second bore of the gland.
