Description
Technical field
The utility model belongs to mould applications, relates to the pressure-plate-force source, specifically a kind of nitrogen spring quick-changing mechanism.
Background technology
Along with the fast development of mould industry, the mould quality requirements increases day by day, and as the pressure-plate-force source, nitrogen spring receives the favor of more and more mould producers with the service life of its stable performance, superelevation than common spring.That one mold needs at least is several, need at most tens so that the dozens of nitrogen spring come binder, so the installation of nitrogen spring and changing has just taken mould assembling and commissioning staff a large amount of man-hour.
The conventional mounting mode of nitrogen spring has substantially that counterbore is installed, the bottom screw is installed, the kerve pressing plate is installed, go up the groove snap ring installs and radially holds tightly several kinds of installations etc., all need lean on several screws to come fastening nitrogen spring.
The nitrogen spring use amount is huge in the mould at present, in the process of die debugging and use, needs the repeated disassembled and assembled nitrogen spring unavoidably.Just several kinds of mounting means of existing nitrogen spring when needing to change nitrogen spring, just must could take out all screw complete removals with nitrogen spring, very waste time and energy, and its fixed head also must take off simultaneously the replacing nitrogen spring time; And when once more nitrogen spring being installed, also need again fixed head and nitrogen spring are combined, and find the installation site; Join and play screw; Operating process is quite loaded down with trivial details, and it is very low to change efficient, brings very burden for the debugging and the use of mould; Have a strong impact on the manufacturing cycle of mould, cause the significant wastage of man-hour and cost.
The patent No. is the Chinese utility model patent of 201020199973.X; " a kind of novel die erecting device " disclosed; Mainly comprise eccentric wheel, pressing plate, spring, installing plate; Specifically be that mould is placed on the installing plate, the eccentric stiffener that eccentric wheel, pressing plate and spring constitute is equipped with in installing plate inside, and eccentric wheel is through in the installing plate and is installed in the rotating shaft.After mould put in place, the operator utilized the rotating shaft rotation that eccentric wheel is rotated 180 degree, just pressing plate is pushed in the locating slot on the mould, can realize the location and compress; When needs unload mould, turnback is returned in rotating shaft, pressing plate withdraws from mold slots under spring action.Mould no longer receives the external force effect, and the operator can easily pull out mould.This product patent solves is that the mould of brake pad material utilizes bolt to be pressed on conventional method on the workbench to mould; Overcome the accurately problem of location, troublesome poeration, inconvenient installation, utilized rotating shaft rotating band movable eccentric wheel, thereby pressing plate has been pushed in the locating slot on the mould; But this patent can't realize thoroughly locked; Rotating shaft can be rotated easily, in case the phenomenon of being rotated will cause the unstable safety problem of mold position.
Summary of the invention
The technical problem that the utility model will solve provides a kind of nitrogen spring quick-changing mechanism, need not to dismantle fixed head and trip bolt, only needs simple rotation quick change screw rod, just can nitrogen spring be taken out, and convenient and swift, efficient is high; When utilizing this mechanism that nitrogen spring is installed, also have " being automatically locked " function, make that the installation of nitrogen spring is very reliable and stable, improved the safety coefficient of mould greatly, effectively promote the mould quality.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
A kind of nitrogen spring quick-changing mechanism; Be used for nitrogen spring is positioned mould or lathe; It comprises quick change bolt, stay and eccentric wheel, spring, and the quick change bolt is located in the quick change bolt hole that fixedly installs, and is set with the eccentric wheel of being located in the stay on the quick change bolt; Eccentric wheel has spring, and the bottom position of spring is fixed; Latch segment is a block structure that the side is a C shape cambered surface, is the piece shape that a lateral edges has the C v notch v; The bottom groove of the thickness of C v notch v, curvature and nitrogen spring is suitable; Be provided with the eccentric wheel chamber that is connected as a single entity with the quick change bolt hole around the quick change bolt hole of latch segment bottom, eccentric wheel is provided with eccentric wheel in the chamber, and wheel chamber height is greater than eccentric wheel thickness; The eccentric wheel chamber of latch segment is divided into two-layer, and it is the eccentric wheel draw-in groove suitable with the eccentric wheel size at the middle and upper levels, and lower floor is for holding eccentric wheel in the rotation vallecular cavity that wherein rotates.
The utility model is through the downward promotion compression spring of quick change bolt, and eccentric wheel is gone in the eccentric wheel draw-in groove, latch segment and nitrogen spring locking.Only need simple rotation quick change bolt, just can realize the replacing of nitrogen spring.
