Description
Technical field
The utility model relates to a kind of parts of lathe.
Background technique
Creeping phenomenon in mechanology, in sliding friction pair driven member at the uniform velocity drive and under certain friction condition the periodicity that produces stop-and-go or time slow time fast motion artifacts.Creeping is a kind of form of self-excited vibration in mechanical vibration.
Each cycle of creeping divides two stages: one is the storage of energy, and another is the immediately release of energy when reaching critical value.Creeping is abnormal motion state common in machine tool slide guide rail (see machine tool guideway).Creep when degree is lighter and show as the vibration that naked eyes can not discover, time remarkable, show as beating of larger distance.Creep and significantly can reduce the machining accuracy of workpiece.In addition, the impact that may cause when automobile clutch engages, contingently when finely tuning some instrument quivers, and is also all the example of creeping.Creep and mostly occur when low speed.
Creep refer to machine tool motion component at a slow speed dynamic row time not stationarity, show as regular one and stop one and jump.This phenomenon occurs now and then when cutting, and when the working shaft often occurred on lathe drives planker to cut, can have a strong impact on surface quality and the dimensional accuracy of work.
Model utility content
The utility model is intended to provide a kind of lathe pneumatic planker damped cylinder, to reduce the creeping phenomenon occurred in lathe work.
The pneumatic planker damped cylinder of lathe in this programme, comprise cylinder body, piston is provided with in cylinder body, the piston rod connected with piston stretches out cylinder body for connecting with the planker of lathe, planker work is driven when piston moves from right to left, cylinder body is divided into two chambers in left and right by piston, left and right chamber is connected by oil pipe, in oil pipe, the side of metering hole is provided with plunger with gap, be connected with between plunger and oil pipe and order about its spring near metering hole, inwall right part in cylinder body is provided with the oil groove of corresponding piston portion working stroke, piston oil groove when being provided with the some work stroke of oil groove is communicated with left and right chamber.
This device uses as the damped cylinder of lathe, connected by piston rod with the flexible working beam on lathe or planker, to change the speed of work, thus improves the surface quality of workpiece.
Specifically, when mobile working is turned left on the piston right side, because the inwall right part in cylinder body is provided with the oil groove of corresponding piston portion working stroke, so the oil of piston left chamber part can flow to right chamber by oil groove, the oil of part is also had to flow into right chamber by the gap of metering hole in oil pipe and plunger.When piston moves to the part not having oil groove, oil then can only flow into right chamber by oil pipe, and due to the minimizing of flow, the speed of piston is bound to slow down, and brings larger damping to prepare to stop helping lathe to slow down further.When piston returns from left to right, oil brings certain hydrodynamic pressure to the plunger in metering hole, and plunger, under the action of the spring away from metering hole, makes the gap between plunger and metering hole increase, and realizes refluxing fast.
Further, plunger is connected on oil pipe by screw flight, is connected between plunger with screw rod by stage clip.The initial distance of threaded adjustment plunger and metering hole can be passed through, to change the flow velocity of initial oil.
Further, corresponding with metering hole on plunger face is taper.To realize better flow control effect.
Further, cylinder wall is provided with venting plug.For discharging the gas in grease chamber.
Accompanying drawing explanation
Fig. 1 is the schematic front view of the utility model embodiment.
Embodiment
Below by embodiment, the utility model is described in further detail:
Reference character in Figure of description comprises: cylinder body 1, piston 2, piston rod 3, oil groove 4, oil pipe 5, metering hole 6, screw rod 7, stage clip 8, conical plug 9.
Embodiment is substantially as shown in Figure 1: cylinder body 1 is in horizontal positioned, and piston rod 3 right-hand member connected with piston 2 is for connecting with the planker on lathe.Inwall is provided with the oil groove 4 of four substantially horizontals in cylinder body, oil groove is uniform along piston rod circumference, and oil groove is distributed on the stroke of inboard wall of cylinder block right part 2/3rds, and the piston stroke of inboard wall of cylinder block left part 1/3rd is not provided with oil groove.
Be communicated with by oil pipe 5 in the bottom at two ends, cylinder body left and right, right part in oil pipe is provided with metering hole 6, in oil pipe above metering hole, scyewed joint has screw rod 7, the bottom of screw rod is connected with conical plug 9 by stage clip 8, conical plug and metering hole have certain primary clearance, when after turn screw rod, the stroke of conical plug can move up and down, thus change the gap between conical plug and metering hole.Meanwhile, when the oil in cylinder body upwards flows from the below of metering hole, the flowing of oil can be pushed conical plug and be moved up, and increases the gap between conical plug and metering hole further, makes oil can pass through oil pipe faster.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the embodiment in specification etc. record the content that may be used for explaining claim.
