Detailed description of the invention
The technique effect for the benefit of understood technical characteristic of the present utility model, content and advantage and can reach, now by the utility model by reference to the accompanying drawings, and be described in detail as follows with the expression-form of embodiment, and wherein used accompanying drawing, its purport is only the use of signal and aid illustration book, for the actual proportions after the utility model enforcement and precisely may not configure, therefore the ratio of accompanying drawing that should be just not appended and configuration relation are understood, limited to the interest field of the utility model on reality is implemented, conjunction is first chatted bright.
Advantage of the present utility model, feature and the technique effect reached will be explained in more detail by referring to exemplary embodiments and accompanying drawing and be easier to understand, and the utility model or can realize in different forms, therefore should not be understood the embodiment being only limitted to the statement of this place, on the contrary, for art those of ordinary skill, the embodiment provided will make the disclosure more thorough with comprehensively and intactly pass on category of the present utility model, and the utility model will only be claim defined.
Referring to figs. 1 through the sectional view that Fig. 3, Fig. 1 are drum type brake polishing wheel of the present utility model; Fig. 2 is the first schematic diagram of drum type brake polishing wheel of the present utility model; Fig. 3 is the second schematic diagram of drum type brake polishing wheel of the present utility model.As figure depicted, the utility model provides a kind of drum type brake polishing wheel 10, and it comprises grinding body 20, back of the body pile layer 30 and fixed jig 40.
Grinding body 20 cylindrically, grinding body 20 has grinding space 22, when carrying out grinding operation to workpiece 90 (as shown in Figure 4) to be ground, just workpiece 90 is placed among grinding space 22, and by the internal face grinding space 22, grinding operation is carried out to the surface of this workpiece 90.Wherein, one end of grinding body 20 has opening 21, and grinding space 22 is extended internally by this opening 21 to be formed.Back of the body pile layer 30 is arranged at the other end of grinding body 20, that is, be positioned at one end of grinding body 20 opposed open 21.Fixed jig 40 links the one side of the relative grinding body 20 of back of the body pile layer 30, and fixed jig 40 is along the outer surface formation concentric shell 41 of grinding body 20, coated and the outer surface of sheathed grinding body 20 of concentric shell 41, wherein, fixed jig 40 can be metal fixture, or with the tool that metal or macromolecular material are made.
In addition, drum type brake polishing wheel 10 of the present utility model also can comprise multiple perforation 11 and multiple keeper 12, each perforation 11 is through to grinding body 20 by fixed jig 40 through back of the body pile layer 30, that is each perforation has run through grinding body 20, back of the body pile layer 30 and fixed jig 40; And then each keeper 12 just can be worn to each perforation 11 of correspondence by the one side of fixed jig 40 relative back of the body pile layer 30, and makes grinding body 20, back of the body pile layer 30 and fixed jig 40 interconnected fixing.But, above are only citing, should as limit.
With reference to the grinding schematic diagram that Fig. 4, Fig. 4 are drum type brake polishing wheel of the present utility model.As shown in Figure 4, when practical application drum type brake polishing wheel 10 of the present utility model carries out grinding operation, workpiece 90 first be placed among the grinding space 22 of grinding body 20 by need, and further the surface to be ground of workpiece 90 is butted on the inner surface in grinding space 22; And then, treat that drum type brake polishing wheel 10 of the present utility model drives grinding body 20 to rotate by fixed jig 40, grind to make the surface of the inner surface in grinding space 22 to workpiece 90.
Further, grinding body 20 can comprise two-layer overcoat 23 and grinding layer 24, is formed with the structure of grinding layer 24 between two-layer overcoat 23.In other words, the contiguous outer surface being arranged at this grinding body 20 of wherein one deck overcoat 23 of this grinding body 20, another overcoat 23 then vicinity is arranged at the inner surface of this grinding body 20, namely grinds the internal face in space 22.
Overcoat 23 can be made up of resin material.Grinding body 20 can comprise expanded material, grinding-material and blowing agent.On the other hand, grinding layer 24 can be multiple hole structure, and can expanded material, grinding-material and blowing agent form via foaming program.Wherein, grinding-material can be the mixture of cerium oxide, aluminium oxide and polycrystalline diamond powder.
In addition, the shape of carrying on the back pile layer 30 may correspond to the shape of the disk body section 42 in fixed jig 40; In more detail, because the disk body section 42 of fixed jig 40 is disc-shaped structure, therefore, carry on the back pile layer 30 and correspond to the disc-shaped structure that diameter corresponds to disk body section 42.Whereby, while the adhesive force providing good can be reached, also too material is not wasted.
As shown in Figures 2 and 3, one end that fixed jig 40 carries on the back pile layer 30 relatively can have combination section 43, and combination section 43 can in order to be connected to milling apparatus 50; Wherein, combination section 43 can be cylindrical-shaped structure, and combination section 43 can be made of one piece with disk body section 42, also can utilize lock, combination section 43 is fixed on disk body section 42 by close-fitting, the mode such as welding; On the other hand, one end of unfixing with disk body section 42 combination section 43 can be provided with the screw rod of predetermined dimension or common-use size, to connect milling apparatus 50.But, above are only citing, should as limit.
In sum, drum type brake polishing wheel of the present utility model grinds workpiece with internal layer lapping mode, so-called internal layer grinding refers to: at high speed, the actual grinding contact surface of polishing wheel is its inner layer surface (being the internal face in grinding space), therefore, the consumption of polishing wheel is also from the inside to the outside.Drum type brake polishing wheel of the present utility model, by this lapping mode, to make polishing wheel in time grinding rear thickness and be thinning, only need can compensate to most suitable abrasion site and angle by adjustment part mould platform moving direction (lateral attitude); On the other hand, drum type brake polishing wheel of the present utility model by grinding this body profile concentrically shell, produces problem that is eccentric, deformation to avoid grinding body when the high speed operation, and then improves durable tolerance and the concentricity of grinding body.
The foregoing is only illustrative, but not be restricted.Anyly do not depart from spirit of the present utility model and category and to its equivalent modifications of carrying out or change, all should comprise within the scope of the appended claims.
