Abstract
A locking mechanism of a connecting rod and a ball screw rod of a press machine comprises the connecting rod, a hinge pin, a bolt, a large-diameter sealing ring, a one-way valve type oil nipple, a small-diameter sealing ring, the ball screw rod, a thin-wall threaded sleeve, a pressure relief screw, a flange plate and a hydraulic cylinder. According to the principle of the locking mechanism of the connecting rod and the ball screw rod of the press machine, hydraulic oil is injected in a cylinder body through an oil injector from the one-way valve type oil nipple, under the action of the hydraulic oil, due to the fact that the wall of the thin-wall threaded sleeve is thin, the thin-wall threaded sleeve retracts and deforms, and the portion, in the thin-wall threaded sleeve, of the ball screw rod is locked. The locking mechanism of the connecting rod and the ball screw rod of the press machine has the advantages of being simple in structure, large and even in locking force and reliable in locking. The shortages that abnormal work of the press machine is prone to occurrence and device safety accidents are prone to occurrence can be effectively overcome.
Description
Technical field
The present invention relates to forcing press, be specifically related to the retaining mechanism of punching machine connecting rod and ball screw, belong 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 object of the invention is to: for connecting rod and the existing above-mentioned defect of ball screw retaining mechanism of existing machinery forcing press, the invention provides a kind of novel press connecting rod and ball screw retaining mechanism, overcome the existing above-mentioned defect of existing machinery press connecting rod and ball screw retaining mechanism.
The present invention realizes the technical scheme that above-mentioned purpose adopts: described a kind of press connecting rod and ball screw retaining mechanism, and 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 in the internal thread of thin-walled thread bush and connecting rod by the external screw thread at its screw mandrel position, in the space that cylinder body and thin-walled thread bush seal, be marked with hydraulic oil.
Operation principle of the present invention 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; when 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 the ball screw at position, place is locked.
Beneficial effect: can be found out by operation principle of the present invention and structural front view, that the present invention has advantages of is simple in structure, coupling mechanism force is large, coupling mechanism force evenly, reliable lock, can effectively avoid therefore and the easy build-up of pressure machine work producing is undesired, the defect that easily causes device security accident.
Accompanying drawing explanation
Accompanying drawing is structural principle front view of the present invention;
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
In one end of thin-walled thread bush (8), be shaped with ring flange (10), 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 in the internal thread of thin-walled thread bush (8) and connecting rod (1) by the external screw thread at its screw mandrel position, 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), when being adjusted to the position needing, now, pressure release screw (9) is fastening, 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 the ball screw at position, place (7) is locked.
