Description
Technical field
The utility model relates to the grinding field, particularly a kind of Carborundum wheel dressing tool.
Background technology
The use of Hardmetal materials in the machine-building process is more and more general, the thinking of the processing method of Hardmetal materials workpiece has been become our important subject.Hardmetal materials hardness is high, and is more crisp, often easily cracks in process.And Hardmetal materials is through being commonly used to make precision cutting tool, and it is very high that the form and position tolerance of cutter generally all requires, and therefore, in our actual production process, Carborundum wheel processing rigid alloy cutter commonly used is to satisfy the Geometrical Tolerance Principle of cutter.
In the process of Carborundum wheel Pattern In Grinding Cemented Carbide cutter, because the restriction of the shape of a part of cutter, Carborundum wheel can only be used transverse grinding, can not cover whole Carborundum wheel working face, like this working face of Carborundum wheel because of wear and tear inhomogeneous occur uneven, contour shape also can change, although the variation of profile is microcosmic, very little, but the requirement on machining accuracy of hard alloy cutter is high, the uneven machining accuracy that can affect hard alloy cutter of the working face of Carborundum wheel, at this time just need to repair emery wheel, make it recover desirable profile.
The utility model content
The utility model is in order to overcome defective in the above-mentioned prior art, provide a kind of simple and reasonable, finishing Carborundum wheel efficient is high, precision is high, easy to operate Carborundum wheel dressing tool.
For achieving the above object, provide a kind of Carborundum wheel dressing tool according to the utility model, comprising: silicon carbide grinding wheel, and support fixedly axle and the locking nut of silicon carbide grinding wheel; Axle is the multidiameter structure, comprising: the little drive stud in journal axle and right side in the left side, and in the left side stop lug between the little drive stud of journal axle and right side, and the outer face of the little drive stud of journal axle and right side offers respectively centre bore in the left side; Silicon carbide grinding wheel is located on the little drive stud in right side, and is screwed on the little drive stud in right side by locking nut, so that silicon carbide grinding wheel is locked between stop lug and the locking nut.
In the technique scheme, right side path double-screw bolt diameter is 22mm, and locking nut is the M22 hex nut.
In the technique scheme, silicon carbide grinding wheel is discoid.
In the technique scheme, the material of silicon carbide grinding wheel is green silicon carbide.
Compared with prior art, the utlity model has following beneficial effect: this Carborundum wheel dressing tool is simple and reasonable, can repair fast voluntarily skive at production station, saved skive has been sent to the outer committee great number cost that former emery wheel specialized factory repairs, finishing Carborundum wheel efficient is high, precision is high, and is easy to operate.

Description of reference numerals:
The 1-silicon carbide grinding wheel, journal axle in the 21-left side, the little journal axle in 22-right side, 23-stop lug, 3-locking nut.
The specific embodiment
Below in conjunction with accompanying drawing, a specific embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of the specific embodiment.It will be appreciated that, mentioned in the following embodiment of the present utility model " on ", D score, " left side ", " right side ", " front " and " reverse side " be all take the direction shown in each figure as benchmark, these words that are used for limiting direction only are for convenience of explanation, do not represent the restriction to the concrete technical scheme of the utility model.
The skive that Carborundum wheel dressing tool of the present utility model utilizes silicon carbide grinding wheel to come the harder diamond that more is difficult to process of grinding dressing to make, can effectively also repair fast skive, make it recover the ideal operation profile, avoid causing the working face of Carborundum wheel because of the inhomogeneous machining accuracy that uneven contour shape affects hard alloy cutter that occurs of wearing and tearing because of unidirectional grinding.Adopt this Carborundum wheel method for trimming just can be the Carborundum wheel reparation as before between 10 to 20 minutes in the production scene, then again fast for the production of, improved production efficiency.
As depicted in figs. 1 and 2, the concrete structure of this Carborundum wheel dressing tool comprises: silicon carbide grinding wheel 1, and support axle and the locking nut 3 of fixing this silicon carbide grinding wheel 1.
Wherein, silicon carbide grinding wheel 1 adopts carbofrax material to make, and is fit to the processing hard brittle material, but the larger material of inapplicable processing toughness.Silicon carbide grinding wheel 1 is discoid, and the center offers the axis hole of crossing that vertically runs through the disk upper and lower end face, and this is crossed axis hole and is used for wearing axle.
The material of silicon carbide grinding wheel 1 is preferably green silicon carbide, and color is green, more is fit to the processing hard brittle material, but the larger material of inapplicable processing toughness.Characteristic of property is: one, and abrasive particle is sharp, and hardness is high, is fit to the hard brittle materials such as Pattern In Grinding Cemented Carbide, optical glass, pottery, alloy, for example Carborundum wheel; Two, fragility is larger, keeps corner angle relatively poor, the larger workpiece of inapplicable processing toughness; Three, thermal conductivity is good, the suitable grinding yielding workpiece that is heated; Four, because its material itself is sharper, also can be used for the products such as processing gem.
Axle is the multidiameter structure, comprising: journal axle 21 and right side path axle 22 in the left side, and in the left side stop lug 23 between journal axle 21 and the right side path axle 22.Wherein, the center, right side of the center, left side of journal axle 21 and right side path axle 22 offers respectively centre bore in the left side, is used for locating with grinding machine thimble clamping; Offer external screw thread on the right side path axle 22, diameter can be 22mm, adaptively is inserted into the crossing in the axis hole of silicon carbide grinding wheel 1; At this moment, the diameter of stop lug 23 is greater than the axis hole of crossing of silicon carbide grinding wheel 1, and its right end face props up the left side of silicon carbide grinding wheel 1.
During this Carborundum wheel dressing tool assembling, first silicon carbide grinding wheel 1 is located on the right side path axle 22 of axle by crossing axis hole, and promote left to make it prop up stop lug 23 backstops, then be screwed on the right side path axle 22 by locking nut 3 and finish assembling from right side locking silicon carbide grinding wheel 1.
As shown in Figure 3, the method for trimming of this Carborundum wheel need to be used above-mentioned Carborundum wheel dressing tool, and concrete steps comprise:
Step 2 is repaired the Carborundum wheel dressing tool fast by the long feed method of utilizing plain external grinding machine, until recover the ideal operation profile.
When utilizing plain external grinding machine finishing Carborundum wheel, generally get little rotating speed and the little amount of feeding, length feed amount f=0.008mm/r, trimming wheel back engagement of the cutting edge can suitably get greatly, emery wheel circumferential speed v=35m/s.
This Carborundum wheel dressing tool is simple and reasonable, can repair fast voluntarily skive at production station, saved skive is sent to the outer committee great number cost that former emery wheel specialized factory repairs, and finishing Carborundum wheel efficient is high, precision is high, and is easy to operate.
Above disclosed only be several specific embodiment of the present utility model, still, the utility model is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
