Abstract
One has waterproof, hanging wire guiding, Combined line cutting guide wheel assembly, and it comprises guide wheel 1, bearing 2, plastic shaft bearing sleeve 3, bearing holder (housing, cover) plastic end cover 4, rubber ring 5, rubber ring 6, bearing holder (housing, cover) retainer ring 8, hanging wire guide ring 9.It is characterized in that: rubber ring 5 and bearing holder (housing, cover) plastic end cover 4 side close contact form water-retaining structure, rubber ring 6 also a small amount of water of entry deterrence can flow to the second water-retaining structure of bearing along guide wheel shaft, the discharge outlet 7 being located at plastic shaft bearing sleeve lowest part forms discharge structure.Form hanging wire guide frame with chamfered portion hanging wire guide ring 9, complete hanging wire and import guide wheel V-type groove function.The utility model also uses structure by dash and draining, and bearing life is improved a lot; Make regular job more convenient by hanging wire guide ring; The guide wheel shaft bearing sleeve overall structure of low cost makes replacing guide wheel assembly efficient and convenient, and installation quality is higher.
Description
Technical field
The utility model relates to to-and-fro thread line cutting technology, specifically refers to that one has waterproof, hanging wire guiding, Combined guide wheel assembly.
Background technology
It is the guide wheel assembly that miniature bearing is housed that to-and-fro thread wire cutting machine tool positions critical component to its tool-electrode molybdenum filament, and liquid cooling chip removal must be rushed with cooling work liquid to molybdenum filament again in electric discharge machining process, working solution like this with the metal particle cut down is easy to flow to (as Fig. 1) in common guide wheel assembly, cause the bearing Fast Wearing in guide wheel assembly, cause the positioning precision of guide wheel to decline, cut out substandard product.
In cutting on line processing, operator often carries out reeling off raw silk from cocoons, hanging wire operation, but the V-type channel opening of guide wheel very little (about 1 millimeter), so often there is molybdenum filament be not suspended to situation on wheel, produces the serious consequence damaged guide wheel assembly, cut useless workpiece.
For traditional guide wheel assembly, major part bearing is contained in centre with in the copper guide wheel cover of insulating barrier, because copper guide wheel cover cost is higher, when changing guide wheel, bearing at every turn, useless guide wheel, useless bearing must be taken out, and clean copper sheathing from copper guide wheel cover, then reinstall new bearing, new guide wheel, bothersome, effort, time-consuming.In addition, be also meticulous work for installation bearing, guide wheel, careless slightly meeting causes damage to new bearing, new guide wheel.
Summary of the invention
There is above-mentioned deficiency for prior art, this practical one of designing has waterproof, hanging wire guiding, Combined line cutting guide wheel assembly, thus improving bearing, guide wheel life-span, hanging wire operation is easier, changes guide wheel assembly faster, installation quality is better, and cost is lower.
The technical solution of the utility model is:
Have waterproof, hanging wire guiding, Combined line cutting guide wheel assembly, it comprises: guide wheel 1, bearing 2, plastic shaft bearing sleeve 3, bearing holder (housing, cover) plastic end cover 4, rubber ring 5, rubber ring 6, bearing holder (housing, cover) retainer ring 8, hanging wire guide ring 9.Wherein plastic shaft bearing sleeve 3 bottom is provided with discharge outlet 7, communicate with the breach of bearing holder (housing, cover) retainer ring 8 and hanging wire guide ring 9 breach, it is characterized in that: be stuck in rubber ring 5 and bearing holder (housing, cover) plastic end cover 4 side close contact on guide wheel shaft and form water-retaining structure, being stuck in rubber ring 6 on guide wheel shaft also can stop the water of infiltration to flow to bearing formation second water-retaining structure along guide wheel shaft, is located at the discharge outlet 7 of plastic shaft bearing sleeve 3 bottom and the breach of axle sleeve retainer ring 8 bottom and hanging wire guide ring 9 down gap and forms discharge structure; Hanging wire guide ring 9 with chamfered portion forms hanging wire guide frame.
Described guide wheel 1, bearing 2, plastic shaft bearing sleeve 3, bearing holder (housing, cover) plastic end cover 4, rubber ring 5, rubber ring 6 can be assembled in manufactory, and plastic shaft bearing sleeve 3 and bearing holder (housing, cover) plastic end cover 4 are sticked with glue, and form an individual components, and are bilateral symmetry.
The axle of described guide wheel 1 is provided with rubber ring positioning groove.
Described hanging wire guide ring 9 respectively has convex-concave ditch platform to be convenient to locate with bearing holder (housing, cover) retainer ring 8 joint portion.
The utility model beneficial effect: the utility model have employed dash and draining also uses structure, effectively stops water to flow to bearing, greatly extends guide wheel, bearing life.Hanging wire guider facilitates regular job, monoblock type guide wheel, bearing arrangement, and because materials are few, cost is low, can realize disposable namely tearing open and namely use mode, save the plenty of time, and ensure that the assembly quality of guide pulley system.
Accompanying drawing explanation
Fig. 1 is traditional guide wheel assembly schematic diagram.
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated:
As shown in Figure 2: one has waterproof, hanging wire guiding, Combined line cutting guide wheel assembly: it by hanging wire guide ring 9, bearing holder (housing, cover) retainer ring 8 with by guide wheel 1, bearing 2, plastic shaft bearing sleeve 3, bearing holder (housing, cover) plastic end cover 4, rubber ring 5, rubber ring 6, form individual components to lathe assembles again together with form.
Hanging wire guide ring 9, bearing holder (housing, cover) retainer ring 8, the opening all having 4mm wide below, form drainage channel.Hanging wire guide ring 9 has upper 40-50 degree inclined-plane to play hanging wire guide effect, guarantees that molybdenum filament is linked into guide wheel
vin type groove, due to also current direction guide wheel shaft can be reduced with guide wheel crest clearance less (about 0.1mm).
The guide wheel assembly be made up of part 1-part 6 can become well an individual components, so that spot replace by factory's direct-assembling.Its centre bearer bush plastic end cover and guide wheel side clearance are at 0.15mm.Rubber ring 5 is enclosed within the groove on guide wheel shaft, and contacts with guide wheel shaft bush end cap sidewall, plays water-proof function; After a segment distance, the another groove cover of guide wheel shaft has second rubber ring 6 to play block water to flow to bearing along guide wheel shaft, enter the water in plastic shaft bearing sleeve inner chamber, can converge to lowest part discharge outlet 7 and flow out, and can not flow to bearing for minute quantity.
Plastic shaft bearing sleeve and bearing holder (housing, cover) plastic end cover 4 select engineering plastic nylon to make, and blend compounds sticks into one.
Guide wheel shaft bush retainer ring 8 available metal is processed, and hanging wire guide ring 9 can be finished with plastic, and these two parts from reusing, can reduce lathe use cost.
It is all same as the prior art that the utility model does not relate to part, maybe can adopt existing techniques in realizing.
