Abstract
The utility model relates to a mode-locking crosshead stress locknut device. The mode-locking crosshead stress locknut device comprises a mode-locking machine hinge assembly, a mode-locking piston rod, a mode-locking crosshead, a stress locknut, a spring washer and a right-handed anti-loosening tightening screw, wherein outer threads, connected with the mode-locking piston rod, of the stress locknut when in stress is designed to left-handed threads, the right-handed anti-loosening tightening screw is arranged on the end surface of the stress locknut and the center of the mode-locking piston rod, the mode-locking crosshead is firmer through the left-handed threads, the right-handed anti-loosening tightening screw can be tighter when being loosened in an opposite direction, so that the device cannot rotate in two directions, and an absolute anti-loosening purpose can be realized.
Description
Technical field
The utility model relates to the stressed locknut of a kind of locked mode crosshead of injection moulding machine.
Background technology
The stressed stop nut structure of locked mode crosshead of traditional injection machine has to adopt opens half of rear upper stretching screw structure, also there is the retainer nut of employing to add stop washer structure, also there is the pairs of anti-loose nut of employing structure, larger because die sinking is impacted, all may occur loosening and affect accuracy of machines and service life through these stop nuts after a period of time.
Summary of the invention
Technical problem to be solved in the utility model: provide a kind of locked mode crosshead stressed locknut; this stressed stop nut becomes left hand thread with the stressed outer Design of Screw Thread being connected of locking piston bar; at stressed stop nut end face and locking piston bar Center dextrorotation looseness-proof set screw; can make locked mode crosshead more and more fastening by left hand thread; will make dextrorotation looseness-proof set screw more and more fastening if oppositely loosening, reach absolute locking object so both direction all cannot rotate.
The utility model solves the technical scheme that its technical problem adopts: the stressed locknut of a kind of locked mode crosshead, it comprises Mould locking machine hinge component, locking piston bar, locked mode crosshead, stressed stop nut, spring washer, dextrorotation looseness-proof set screw, described locking piston bar is located in the center lock mould oil cylinder of Mould locking machine hinge component, described locked mode crosshead is connected with Mould locking machine hinge component up and down, described locking piston bar left end extension carries out fastening stressed be connected with stressed stop nut with left hand thread engagement through after the centre bore of locked mode crosshead, the right side of described stressed stop nut and center, locking piston bar right side are provided with spring washer and dextrorotation looseness-proof set screw carries out locking fastening.
The beneficial effects of the utility model:
1. reach absolute anti-loosing effect by right-and-left threaded design, make machine can stablize continuous firing, ensure precision and the service life of machine.
