Description
Technical field:
The utility model relates to industrial Linear manipulator technical field, refers in particular to Linear manipulator list oil nozzle Refuel structure.
Background technique:
At present, industry Linear manipulator core work part mainly provides rotating power by motor, make rotating force become translational forces by ball screw, and as straight-line main carrier and guide way, then realize the various effects of mechanism hand by being fixed on slide unit on ball screw nut and linear slide rail slide block by linear slide rail.In sum, when current industrial Linear manipulator is worked, main movement part is linear slide rail and ball screw, and therefore, both lubricating maintenances are quite important.
And being slide block and ball screw nut to linear slide rail, the oiling maintenance mode of current Linear manipulator carries out oil injecting lubricating one by one, because the structure of mechanism hand makes quite inconvenience of maintenance, often need to take apart oiling again after mechanism hand, and part robot manipulator structure even can only be on linear slide rail and ball screw surface oiling but not inject fluid, not only increase cost of upkeep, and can not effectively ensure the lubrication effect of mechanism hand, affect the working life of mechanism hand.
Model utility content:
The purpose of this utility model is for the deficiencies in the prior art, and provide Linear manipulator list oil nozzle Refuel structure, this structure has solved fluid problems of liquid flow, can effectively ensure the lubrication effect of linear slide rail and ball screw, and an oil nozzle that passes through mechanism hand surface injects fluid nut and each slide block of mechanism hand, easy-to-operat.
For achieving the above object, the utility model adopts following technological scheme, it comprises linear guides, linear guides slide block, ball screw nut, screw mandrel, adds oil clot, fuel filler neck, slide unit, oil-feed piece, oil sealing, linear guides is provided with slide unit, on slide unit, be connected with screw mandrel, slide unit is provided with linear guides slide block, adds oil clot, oil-feed piece, and the side of slide unit is provided with oil sealing, and slide unit is provided with fuel filler neck, ball screw nut.
Described fuel filler neck is at least more than two.
The utility model beneficial effect is: linear guides is provided with slide unit, on slide unit, be connected with screw mandrel, slide unit is provided with linear guides slide block, adds oil clot, oil-feed piece, the side of slide unit is provided with oil sealing, slide unit is provided with fuel filler neck, ball screw nut, by increase oil circuit on mechanism hand slide unit, mechanism hand can be refueled by single oil nozzle to 4 guide rail slide blocks and ball screw, the maintenance that makes to refuel is more convenient, and can effectively ensure lubrication effect, reduce mechanism hand cost of upkeep, improve utilization efficiency.
Brief description of the drawings:
Fig. 1 is to be structural representation of the present utility model.
Fig. 2 is the structural representation for the utility model other direction.
Fig. 3 is the structural representation for the utility model inside slide unit.
Fig. 4 is the structural representation that removes slide unit inside for the utility model.
Embodiment:
See shown in Fig. 1 to Fig. 4: it comprises linear guides 1, linear guides slide block 2, ball screw nut 3, screw mandrel 4, adds oil clot 5, fuel filler neck 6, slide unit 7, oil-feed piece 8, oil sealing 9, linear guides 1 is provided with slide unit 7, on slide unit 7, be connected with screw mandrel 4, slide unit 7 is provided with linear guides slide block 2, adds oil clot 5, oil-feed piece 8, the side of slide unit 7 is provided with oil sealing 9, and slide unit 7 is provided with fuel filler neck 6, ball screw nut 3.
Described fuel filler neck 6 is at least more than two.
Model utility solves the technological scheme that its technical problem adopts: in slide unit 7 materials, increase oil circuit by boring, calculate and can design an oil circuit that makes each slide block and nut in mechanism hand simultaneously inject suitable fluid amount according to the equation of continuity in fluid mechanics and momentum equation, again oil circuit initial position is arranged on to slide unit outer surface, makes its installation oil nozzle and oiling more convenient.
Be below whole model utility inventive principle analytic explanation:
(1), mechanism hand entirety is refueled and is maintained
Mechanism hand refuels maintenance by the single surperficial fuel filler neck 6 that is exposed at, and need not take any part apart, and it is quite convenient to maintain.
(2), mechanism hand needs oiling part structure
Linear motion manipulator main movement part is two linear guides and screw mandrel 4 and slide unit routing motion, and the part that needs to refuel be 4 linear guides slide blocks and ball screw.
(3), oiling mode
1. be directly to inject slide block to linear guides oiling, make between ball and guide rail, to be lubricated in slide block.Because slide position is symmetrical between two, therefore oil circuit is also designed to symmetrical oil circuit, and its oil circuit is by slide unit 7 and add oil clot 5 and form, and adds oil clot 5 oil circuits.
2. be seal oil chamber oiling to ball screw oiling, utilize slide unit 7, feed screw nut 3, oil-feed piece 8 and oil sealing 9 to form a seal space, injecting oil liquid, to reach lubricated screw mandrel object, its effect is similar with injecting feed screw nut, and oil circuit is made up of slide unit and oil-feed piece, when fluid flows out from slide unit oil circuit, can evenly inject seal oil chamber by oil-feed piece, oil-feed piece 8 oil circuits as shown in Figure 4.
(4), slide unit internal oil passages design
According to the position of linear guides and ball screw, utilize fluid mechanics correlation theories knowledge, can calculate and design slide unit internal oil passages in conjunction with actual processing method.
This model utility greatest problem is because of the different caused Volume Changes problems in cross section and fluid suffered change in resistance problem in oil circuit will solve fluid inflow time.Model utility technological scheme logic: establish fluid and arrive feed screw nut through nut pipe, arrive slide block through slider tube.
1. calculate according to volume, nut pipe volume is become to equate with slider tube Volume design, known according to equation of continuity, flow is identical, and fluid arrives resistance cross section simultaneously.
2. according to Force Calculation, because liquid internal pressure equates everywhere, while therefore fluid being arrived separately to resistance cross section, suffered resistance is designed to equate, fluid can inject each associated lubrication part simultaneously, can reach oily object.
Because different model mechanism hand slide unit varies in size, just can reach oily object according to above relation design size as required.According to reality processing, because oil circuit forms for boring, the actual part oil circuit having more can be on perforate end be attacked screw thread, utilize several meters of screws to adjust unnecessary oil circuit length to reach design size and to prevent leakage of oil
The above is only preferred embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
