Abstract
The utility model relates to a connecting rod and bulb screw rod locking mechanism for a press, which comprises a connecting rod, a hinge pin, a bolt, a large-diameter sealing ring, a one-way valve type oil nipple, a small-diameter sealing ring, a bulb screw rod, a thin-wall thread bushing, a pressure relief screw, a flange plate and a hydraulic cylinder. The connecting rod and bulb screw rod locking mechanism for the press adopts the following principle that hydraulic oil is injected into a cylinder body from the one-way valve type oil nipple through an oil injector; under the action of the hydraulic oil, and due to a smaller wall thickness, contraction and deformation of the thin-wall thread bushing, the bulb screw rod at the position is locked. The connecting rod and bulb screw rod locking mechanism for the press has the advantages of simple structure, larger locking force, uniform locking force and reliability for locking and can effectively avoid the generated defects of easiness for causing abnormal operation of the press and easiness for causing safety accidents of equipment.
Description
Technical field
The utility model relates to forcing press, is specifically related to the retaining mechanism of punching machine connecting rod and ball screw, belongs to punching machine technical field.
Background technology
At present, although existing forcing press retaining mechanism is being not quite similar aspect structure and principle, but, generally all there is more or less the defect that coupling mechanism force is less, coupling mechanism force is inhomogeneous, locking effect is poor, and therefore easily the work of build-up of pressure machine is undesired, even easily causes device security accident.
Summary of the invention
The purpose of this utility model is: for connecting rod and the existing above-mentioned defect of ball screw retaining mechanism of existing machinery forcing press, the utility model provides a kind of novel press connecting rod and ball screw retaining mechanism, overcomes the existing above-mentioned defect of existing machinery press connecting rod and ball screw retaining mechanism.
The utility model is realized the technical scheme that above-mentioned purpose adopts: described a kind of press connecting rod and ball screw retaining mechanism, it is by connecting rod, bearing pin, bolt, greatly through sealing ring, check valve-type pump nozzle, path sealing ring, ball screw, thin-walled thread bush, pressure release screw, ring flange, hydraulic cylinder, pressure oil forms, it is characterized in that: one end of thin-walled thread bush is shaped with ring flange, described ring flange is fixed on the lower port position of connecting rod by bearing pin, connecting rod lower port position in ring flange excircle part is mounted with hydraulic cylinder by bolt, between the inner chamber of hydraulic cylinder and the cylindrical of ring flange, be provided with greatly through sealing ring, between thin-walled thread bush lower end and hydraulic cylinder bottom aperture, be provided with path sealing ring, on the outer wall of hydraulic cylinder, install and be provided with check valve-type pump nozzle and pressure release screw respectively, in the endoporus of thin-walled thread bush and the endoporus of connecting rod, be shaped with identical internal thread, ball screw is arranged on by the external screw thread at its screw mandrel position in the internal thread of thin-walled thread bush and connecting rod, in the space that cylinder body and thin-walled thread bush seal, be marked with hydraulic oil.
Operation principle of the present utility model is, by pressure release screw by the hydraulic fluid pressure pressure release in cylinder body, now; thin-walled thread bush is in natural state; ball screw can normally regulate in the internal thread of thin-walled thread bush and ball screw; in the time being adjusted to the position needing; now; by pressure release screw fastening; by oil syringe from check valve-type pump nozzle to cylinder body in injection liquid force feed, under the effect of pressure oil, because thin-walled thread bush has thinner wall thickness; thus shrink distortion, and by locked the ball screw at position, place.
Beneficial effect: can be found out by operation principle of the present utility model and structural front view, the utlity model has that simple in structure, coupling mechanism force is large, coupling mechanism force evenly, the advantage of reliable lock, can effectively avoid therefore and the easy build-up of pressure machine work that produces is undesired, the defect that easily causes device security accident.
Accompanying drawing explanation
Accompanying drawing is structural principle front view of the present utility model;
Shown in figure: 1, connecting rod; 2, bearing pin; 3, bolt; 4, greatly through sealing ring; 5, check valve-type pump nozzle; 6, path sealing ring; 7, ball screw; 8, thin-walled thread bush; 9, pressure release screw; 10, ring flange; 11, hydraulic cylinder; 12, pressure oil.
The specific embodiment
Be shaped with ring flange (10) in one end of thin-walled thread bush (8), ring flange (10) is fixed on the lower port position of connecting rod (1) by bearing pin (2), connecting rod (1) lower port position in ring flange (10) excircle part is mounted with hydraulic cylinder (11) by bolt (3), between the inner chamber of hydraulic cylinder (11) and the cylindrical of ring flange (10), be provided with greatly through sealing ring (4), between thin-walled thread bush (8) lower end and hydraulic cylinder (11) small hole at bottom part, be provided with path sealing ring (6), on the outer wall of hydraulic cylinder (11), install respectively and be provided with check valve-type pump nozzle (5) and pressure release screw (9), in the endoporus of thin-walled thread bush (8) and the endoporus of connecting rod (1), be shaped with identical internal thread, ball screw (7) is arranged on by the external screw thread at its screw mandrel position in the internal thread of thin-walled thread bush (8) and connecting rod (1), in the space of sealing at cylinder body (11) and thin-walled thread bush (8), be marked with hydraulic oil (12).
In use, by pressure release screw (9) by the hydraulic fluid pressure pressure release in cylinder body (11), now, thin-walled thread bush (8) is in natural state, ball screw (7) can normally regulate in the internal thread of thin-walled thread bush (8) and ball screw (7), in the time being adjusted to the position needing, now, by fastening pressure release screw (9), by oil syringe from check valve-type pump nozzle (5) to the interior injection liquid force feed of cylinder body (11) (12), under the effect of pressure oil, because thin-walled thread bush (8) has thinner wall thickness, so shrink distortion, and by locked the ball screw at position, place (7).
