[specific embodiment]
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
As shown in Figure 1, an embodiment of the utility model provides a kind of wire cutting machine guide wheel.This wire cutting machine guide wheel comprises cylindrical shell 1, be located at the guide pipe 2 in the cylindrical shell 1 and be fixed in the end cap 3 at cylindrical shell 1 two ends.The two ends of this guide pipe 2 link to each other with end cap 3.This cylindrical shell 1 is a metal material with end cap 3, links together through scolder between cylindrical shell 1 and the end cap 3.Preferable, cylindrical shell 1 can be alloy with the material of end cap 3, preferable is chromium steel.Because cylindrical shell 1 adopts metal material with end cap 3 and is fixed together through the mode that scolder promptly welds; This wire cutting machine guide wheel has lower cost; Being connected between cylindrical shell 1 and the end cap 3 is also more firm; Be not easy to produce dislocation or guide wheel disintegration, thereby make the wire cutting machine guide wheel have long service life.In addition; Adopt the fixed form of welding can make end cap 3 save elongated surfaces between end cap 3 and the cylindrical shell 1; Perhaps use short elongated surfaces just can guarantee the reliability that is connected between end cap 3 and the cylindrical shell 1, can save material, further reduce cost than the elongated surfaces of weak point.
This wire cutting machine guide wheel also comprises the support of being located in the cylindrical shell 14, and this support 4 is fixed on the outer wall of inwall and guide pipe 2 of cylindrical shell 1.The main effect of this support 4 is the intensity that increases cylindrical shell 1, and its quantity and the position in cylindrical shell 1 can be adjusted as required.Preferable, can the axial direction of support 4 along cylindrical shell 1 evenly be arranged in the cylindrical shell 1, the distance between the promptly adjacent two stands 4 and end cap 3 with equate apart from the distance between the nearest support 4 of end cap 3.Further, support 4 can be set on the guide pipe 2, can carry out spacing to guide pipe 2 like this.
The end cap 3 of this wire cutting machine guide wheel is provided with a plurality of drive holes 6 that match with the drive pin of wire cutting machine.Drive pin can be fixed in this drive hole 6 to drive the rotation of wire cutting machine guide wheel.This drive hole 6 can for a plurality of and on end cap 3 center with end cap 3 be that the center is symmetrical distribution.Also be provided with the counterweight adjustment hole 7 of a plurality of adjusting wire cutting machine guide wheel dynamic balances on the end cap 3.Have screw thread in this counterweight adjustment hole 7, screw can be fixed in the counterweight adjustment hole 7 through screw thread.Counterweight adjustment hole 7 is provided with plumbous or other appropriate filler.When needs are regulated the dynamic balance of cutting machine guide wheel, can regulate through the amount of regulating the filler in the counterweight adjustment hole 7, after regulating, screw is screwed in the counterweight adjustment hole 7, filler just can not spill in the counterweight adjustment hole.
This wire cutting machine guide wheel also comprises female bearing shell 5, and this mother's bearing shell 5 is fixed on the end cap 3.This mother's bearing shell 5 can be fixedly connected with the public bearing shell of wire cutting machine, and wire cutting machine just can drive the guide wheel rotation through female bearing shell 5 and public bearing shell like this.
This wire cutting machine guide wheel comprises that also one deck is coated on the polyurethane coating of drum surface.This polyurethane coating is the wear-resisting elastic coating of one deck.This polyurethane coating is provided with the storage tank of many ccontaining line cutting steel wires, and these storage tanks can be evenly distributed on the wire cutting machine guide wheel.When being installed in this wire cutting machine guide wheel on the wire cutting machine, steel wire will be embedded in these storage tanks, and steel wire just can not deviate from during the rotation of wire cutting machine guide wheel.In addition; The cylindrical shell of this wire cutting machine guide wheel adopts metal material to substitute original carbon fibre material; For here on the cylindrical shell of wire cutting machine guide wheel the coated with polyurethane coating following advantage is arranged: 1, for the wire cutting machine guide wheel of employing carbon fibre material commonly used; In carrying out the cylindrical shell coating procedure of wire cutting machine guide wheel, need vacuumize; The inside of carbon fibre material own has certain bubble, in the process that vacuumizes, can inevitably ooze out a small amount of bubble and get into polyurethane coating, influences coating quality.The wire cutting machine guide wheel of the utility model adopts metal cylinder, does not then have this problem.2, because the metal cylinder surface compact; The interlock meeting of polyurethane coating and metal cylinder is tightr; So the cylindrical shell of the wire cutting machine guide wheel of the utility model and polyurethane coating combine meeting better 3, because the chemical property of metal cylinder is more stable than carbon fiber, so the reliability of the wire cutting machine guide wheel of the utility model can be higher.
During use, at first the wire cutting machine guide wheel is lifted the installation site to the wire cutting machine board; Then with female bearing shell of wire cutting machine guide wheel one end and the public bearing shell interlock on the wire cutting machine board top bearing housing; Again the live bearing case is pushed, dock interlock with female bearing shell of the wire cutting machine guide wheel other end; Then drive pin is inserted in the drive hole on the end cap of wire cutting machine guide wheel, make wire cutting machine guide wheel Primary Location; At last; In the guide pipe of wire cutting machine guide wheel, insert a rhizoid bar; The length of screw mandrel is greater than the length of guide wheel; Fix between screw mandrel and the rigid bearing case, and between the live bearing case through nut check, nut can guarantee that female bearing shell at wire cutting machine guide wheel two ends and the public bearing shell interlock on the wire cutting machine are tight.After the guide wheel installation, gauze can be begun to lay, just the cutting of silicon chip can be carried out then.
The cylindrical shell of the wire cutting machine guide wheel of the utility model and end cap adopt metal material, and the mode through welding between cylindrical shell and the end cap links together.The use of metal material makes this wire cutting machine guide wheel have lower cost; Adopt the mode of welding to be fixedly connected between cylindrical shell and the end cap can to make end cap and cylindrical shell combine more firm; Reducing end cap and cylindrical shell misplaces; The risk that causes line cutting guide wheel to disintegrate, thus the service life that line cuts guide wheel increased.
The above embodiment has only expressed several kinds of embodiments of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
