Abstract

A kind of easy speed is taken out stitches cutting guide wheel, is made up of the nut of tightening at both arms guide wheel, copper sheathing, bearing, guide wheel two ends, and the chamfered portion contacted on the outside of both arms guide wheel with copper sheathing processes two symmetrical blind holes；Two symmetrical blind holes will be perpendicular to inclined-plane, and aperture is 2mm, and depth is 2mm.When changing guide wheel, as long as the guide wheel for unloading either end tightens nut, copper sheathing and bearing are removed, it just can be appreciated that two blind holes on guide wheel inclined-plane, two symmetrical blind holes are blocked with the point pawls of common jump ring pliers, two hand opposite shaft orientations are put forth one's strength, just the nut of the guide wheel other end is unloaded slightly, old guide wheel is easily unloaded, is more renewed.The utility model has the advantages that structure is novel, it is simple, easy to use to process, and efficiently solves that guide wheel one end is frangible, and other end difficulty is unloaded；The problem of one people does not change guide wheel substantially, save the replacing construction of guide wheel or bearing, improve production efficiency and machining accuracy, it is to avoid unnecessary waste.

Description

A kind of easy speed is taken out stitches cutting guide wheel

Technical field the utility model is related to mechanical engineering technical field, and especially a kind of fast quick-detach wire cutting is led Wheel.

Background technology is it is well known that at present in process of manufacture, guide wheel revolves at a high speed in the presence of wire electrode Turn, in order to prevent guide wheel in rotary course or so play, it is very tight that the nut at two ends is twisted, thus causes the inconvenience of dismounting, at present When changing wire cutting guide wheel, it is common practice that：The nut runners of right-hand man Ge Na mono-, set top nut opposite direction twists the spiral shell at guide wheel two ends Mother, as long as but unclamp the nut of wherein one end, the other end with regard to handy pliers clamps the cylindrical of guide wheel, or allows another person Exert oneself to clamp the nut one end unclamped with pliers, guide wheel could be unclamped and dismantled, but this way is deposited and had the disadvantage that：1、 Time-consuming, difficultly, a usual people can not complete, and efficiency is low.2nd, bowlder outside guide wheel is pressed from both sides using pliers, dynamics is difficult to grasp, if firmly It is excessive, easily (ceramic guide wheel is frangible) is caught broken by guide wheel is cylindrical, and the other end for pressing from both sides guide wheel is easily destroyed screw.If the 3, will be more The bearing of guide wheel or so is changed, guide wheel destruction can only together be changed, cause unnecessary waste.These reasons cause in production, Many operators, which do not want to take the trouble, to be unwilling to change guide wheel, so that the surface roughness and machining accuracy of workpiece are influenceed, also influence production Efficiency.

Content of the invention the utility model is now taken out stitches for the deficiency in the presence of prior art there is provided a kind of easy speed Guide wheel is cut, the improvement in hole is processed on the basis of original guide wheel, it is ensured that one man operation can be rapidly completed the dismounting of guide wheel.

The utility model is made up of the nut of tightening at both arms guide wheel, copper sheathing, bearing, guide wheel two ends, outside both arms guide wheel The chamfered portion that side is contacted with copper sheathing processes two symmetrical blind holes；Two symmetrical blind holes will be perpendicular to inclined-plane, and aperture is 2mm, Depth is 2mm.

After said structure, when changing guide wheel, as long as the guide wheel for unloading either end tightens nut, by copper sheathing and bearing Remove, just can be appreciated that two blind holes on guide wheel inclined-plane, two symmetrical blind holes, two palmistrys are blocked with the point pawls of common jump ring pliers Rotary-inversion axis just unloads the nut of the guide wheel other end to putting forth one's strength slightly, easily unloads old guide wheel, more renews.

The utility model has the advantages that structure is novel, it is simple, easy to use to process, and efficiently solves guide wheel one end easy Unload, other end difficulty is unloaded；The problem of one people does not change guide wheel substantially, saves the replacing construction of guide wheel or bearing, improves life Produce efficiency and machining accuracy, it is to avoid unnecessary waste.

Illustrate the profile that Fig. 1 is the utility model guide wheel assembly.

Fig. 2 is the utility model guide wheel profile.

Fig. 3 is the utility model guide wheel top view.

Description of reference numerals：1. nut, 5. blind holes are tightened in both arms guide wheel, 2. copper sheathings, 3. bearings, 4..

Embodiment is by double in the schematic diagram that a kind of easy speed takes out stitches cutting guide wheel as shown in Figure 1-Figure 3 Arm guide wheel 1, copper sheathing 2, bearing 3, the nut 4 of tightening at guide wheel two ends are constituted, the inclined plane part contacted on the outside of both arms guide wheel with copper sheathing It is divided to processing two symmetrical blind holes 5；Two symmetrical blind holes will be perpendicular to inclined-plane, and aperture is 2mm, and depth is 2mm.

During dismounting, nut spanner is enclosed on the fastening nut of left and right, both hands axial direction opposite direction is turned, and one of them is tightened The nut of nut, which loosens, to be backed out, and is unloaded after lower bearing and copper sheathing, it is possible to see the symmetrical two 2mm blind holes in guide wheel side inclined-plane, Symmetrical blind hole is lived with common Circlip tongs subcard, the other end is enclosed on the fastening nut that the other end is not backed out with nut runner, Both hands axial direction opposite direction is turned, it is possible to is unloaded other end fastening nut, and then is unloaded lower bearing, more renews.

It is described above, preferably embodiment only of the present utility model, but protection domain of the present utility model is simultaneously This is not limited to, all those familiar with the art are disclosed in the utility model in technical scope, according to this reality It is subject to equivalent substitution with new technical scheme and its design of the present utility model or changes to cover of the present utility model Within protection domain.

Claims (2)

1. The cutting guide wheel 1. a kind of easy speed is taken out stitches, is made up of the nut of tightening at both arms guide wheel, copper sheathing, bearing, guide wheel two ends, and it is special Levy and be：The chamfered portion contacted on the outside of both arms guide wheel with copper sheathing processes two symmetrical blind holes.
2. The cutting guide wheel 2. a kind of easy speed according to claim 1 is taken out stitches, it is characterised in that：Two symmetrical blind holes will be perpendicular to Inclined-plane, and aperture is 2mm, depth is 2mm.
