Abstract
A kind of nC vertical milling machine hydraulic power unit with defencive function disclosed in the utility model; comprise frame, be arranged on the drive motors in described frame and be connected to the static pressure oil feed pump of output shaft end of described drive motors, also comprise one and be arranged on stored energy mechanism in described frame.The beneficial effects of the utility model are: by setting up stored energy mechanism, drive motors under normal operating conditions, stored energy mechanism energy reserve, when drive motors stops, especially when drive motors stops due to power-off suddenly, stored energy mechanism releases energy and continues the work of band dynamic and static pressure oil feed pump short time until fault offset is complete, during this period, static pressure oil feed pump still continues fuel feeding, doing so avoids the decompression that oil pocket causes because of the unexpected fuel cut-off of static pressure oil feed pump, effectively protect guide rail not by the scratch of the workbench of milling machine, extend the service life of guide rail and workbench.
Description
Technical field
The utility model relates to milling machine technical field, particularly relates to a kind of nC vertical milling machine hydraulic power unit with defencive function.
Background technology
NC vertical milling machine hydraulic power unit adopts hydrostatic slideway technology to be held up by the workbench of milling machine, realizes the static pressure power source of work pieces process.See Fig. 1 and Fig. 2, current nC vertical milling machine hydraulic power unit comprises frame 10, frame 10 is provided with drive motors 20, and the output shaft 21 of drive motors 20 is connected with static pressure oil feed pump 30, works in order to drive static pressure oil feed pump 30.But when drive motors 20 suddenly power-off, static pressure oil feed pump 30 also fuel cut-off immediately, will cause decompression in oil pocket like this and cause milling machine table to abrade guide rail.
For this reason, applicant carried out useful exploration and trial, have found result of the above problems, technical scheme described below produces under this background.
Utility model content
Technical problem to be solved in the utility model: a kind of nC vertical milling machine hydraulic power unit with defencive function is provided for the deficiencies in the prior art; the static pressure oil feed pump of this hydraulic power unit also can continuous service a period of time under powering-off state; avoid the decompression that oil pocket causes because of the unexpected fuel cut-off of static pressure oil feed pump; thus effectively protect guide rail not by the scratch of the workbench of milling machine, extend the service life of guide rail and workbench.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of nC vertical milling machine hydraulic power unit with defencive function; comprise frame, be arranged on the drive motors in described frame and be connected to the static pressure oil feed pump of output shaft end of described drive motors, also comprise one and be arranged on the stored energy mechanism that still can drive described static pressure oil feed pump continuous firing a period of time after described drive motors quits work in described frame.
In a preferred embodiment of the present utility model, described stored energy mechanism comprises:
One power transmission shaft, the extension that one end and the output shaft of described drive motors of described power transmission shaft stretch out bottom drive motors is connected;
Be sheathed on the flywheel on described power transmission shaft; And
Being sheathed on described power transmission shaft and being positioned at the left and right support sleeve of described flywheel both sides, described left and right support sleeve is supported in described frame respectively by left and right supporting seat.
Owing to have employed technical scheme as above, the beneficial effects of the utility model are: by setting up stored energy mechanism, drive motors under normal operating conditions, stored energy mechanism energy reserve, when drive motors stops, especially when drive motors stops due to power-off suddenly, stored energy mechanism releases energy and continues the work of band dynamic and static pressure oil feed pump short time until fault offset is complete, during this period, static pressure oil feed pump still continues fuel feeding, doing so avoids the decompression that oil pocket causes because of the unexpected fuel cut-off of static pressure oil feed pump, effectively protect guide rail not by the scratch of the workbench of milling machine, extend the service life of guide rail and workbench.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See a kind of nC vertical milling machine hydraulic power unit with defencive function provided in Fig. 3 and Fig. 4, figure, comprise frame 100, drive motors 200, static pressure oil feed pump 300 and stored energy mechanism 400.
Drive motors 200 traverse is fixed in frame 100, the end of the output shaft 210 of drive motors 200 is connected with static pressure oil feed pump 300, work in order to drive static pressure oil feed pump 300, stored energy mechanism 400 is arranged in frame 100, and be positioned at the side of drive motors 200, stored energy mechanism 400 is after drive motors 200 quits work, especially when drive motors 200 runs into unexpected power-off, still can drive static pressure oil feed pump 300 continuous firing a period of time, during this period, static pressure oil feed pump 300 still can continue fuel feeding, doing so avoids the decompression that oil pocket causes because of the unexpected fuel cut-off of static pressure oil feed pump 300, effectively protect guide rail not by the scratch of the workbench of milling machine, extend the service life of guide rail and workbench.
Preferably but not the mechanism of the stored energy mechanism 400 be definitely limited to is as follows: it comprises power transmission shaft 410, flywheel 420 and left and right flywheel axle sleeve 430,440.The extension 211 that one end 411 of power transmission shaft 410 is stretched out bottom drive motors 200 with the output shaft 210 of drive motors 200 is connected by shaft coupling 412, flywheel 420 is sheathed on power transmission shaft 410, left and right flywheel axle sleeve 430,440 to be sheathed on power transmission shaft 410 and to lay respectively at the both sides of flywheel 420, and left and right flywheel axle sleeve 430,440 is supported in frame 100 respectively by left and right supporting seat 431,441.Drive motors 200 under normal operating conditions, while working with dynamic and static pressure oil feed pump 300, also flywheel driven 420 rotates, flywheel 420 energy reserve, when drive motors 200 stops, especially when drive motors 200 stops due to power-off suddenly, under effect of inertia due to flywheel 420, flywheel 420 continues through output shaft 210 and is with dynamic and static pressure oil feed pump 300 short time to work, till the fault offset that flywheel 420 is laid in.
