Description
Technical field
This utility model relates to grinding tool technical field, particularly relates to a kind of emery wheel.
Background technology
Emery wheel is the one that in grinding tool, consumption is maximum, use face is the widest, high speed rotating when emery wheel uses, and can roughly grind metal or the cylindrical of non-metal workpiece, inner circle, plane and various profiles etc., partly refine and refine and fluting and cut-out etc..Emery wheel is in grinding process, and the grinding granule of wheel face constantly comes off, life-time service, and the external diameter of emery wheel can reduce, when, after the abrasion to a certain degree of emery wheel external diameter, emery wheel is scrapped, and needs the emery wheel more renewed.Common emery wheel is the most in the form of annular discs, and centre arranges centre bore, when emery wheel is scrapped, also leaves longer distance between its external diameter and endoporus, and along with the progress of emery wheel technology, the material cost of emery wheel improves day by day, causes emery wheel material to be wasted when plain wheel is scrapped.And the weight of emery wheel is relatively big, the when of high-speed rotation, centrifugal force is relatively big, and emery wheel is easily generated vibrations and causes grinding accuracy to reduce, and energy consumption of electrical machinery is bigger.
Utility model content
This utility model is for the problem solving easily to shake when emery wheel of the prior art exists waste of material, high-speed rotation, it is provided that a kind of can effectively reduce waste of material, improve rotational stability grinding wheel structure.
To achieve these goals, this utility model adopts the following technical scheme that
A kind of grinding wheel structure, including emery wheel body, the center of described emery wheel body is provided with endoporus, is provided with aluminum core in described endoporus, and the center of described aluminum core is provided with centre bore, and the diameter of described endoporus is 0.60-0.75 with the ratio of the external diameter of emery wheel body；The hole wall of described endoporus is provided with annular boss, the periphery, two ends of described aluminum core is provided with annular breach, it is provided with ring baffle in described annular breach, described ring baffle and endoporus matched in clearance, between the bottom of annular breach, it is provided with some circumferentially distributed connection through holes on described aluminum core, ring baffle is provided with the connecting hole corresponding with connecting through hole, is connected by bolt, nut between ring baffle with aluminum core.Endoporus aperture on emery wheel body increases, and eliminates invalid milled portion, and the material of emery wheel body saves about 30%, the overall weight saving of emery wheel about 25%, during emery wheel high-speed rotation, centrifugal force reduces, vibrations reduce, rotating more stable, grinding accuracy improves；After emery wheel is scrapped, aluminum core, ring baffle can be reused.
As preferably, described aluminum core and the inner ring matched in clearance of annular boss, it is filled with high-temperature plastic between aluminum core and the inner ring of annular boss.It is connected by high temperature resistant glue between aluminum core with emery wheel body, good stability, effectively prevents from relatively rotating between the two.
As preferably, described annular boss is provided with some locating slots, and described aluminum core periphery is provided with the positioning boss coordinated with locating slot.Positioning boss on aluminum core snaps in locating slot, thus ensures synchronous axial system between the two.
As preferably, the cross section of described locating slot is curved.Arc can reduce locating slot and add the stress concentration produced man-hour so that emery wheel body is more stable.
Therefore, this utility model has the advantages that the material of (1) emery wheel body reduces, and reduces manufacturing cost；(2) whole emery wheel weight saving, during high-speed rotation, centrifugal force reduces, and shakes little during rotation；(3) circumference of emery wheel body by locating slot, positioning boss spacing, and be connected with aluminum core by high temperature resistant glue, spacing by ring baffle of emery wheel body axial, overall performance is stable, reliable.

In figure: emery wheel body 1, endoporus 2, aluminum core 3, annular breach 30, connection through hole 31, centre bore 4, annular boss 5, locating slot 6, positioning boss 7, ring baffle 8, bolt 9, nut 10.
Detailed description of the invention
With detailed description of the invention, this utility model is further described below in conjunction with the accompanying drawings:
A kind of grinding wheel structure as shown in figures 1 and 3, including emery wheel body 1, the center of described emery wheel body is provided with endoporus 2, aluminum core 3 it is provided with in endoporus, the center of aluminum core is provided with centre bore 4, the diameter of endoporus 2 is 0.60-0.75 with the ratio of the external diameter of emery wheel body 1, as shown in Figure 2 and Figure 4, the hole wall of endoporus is provided with annular boss 5, annular boss 5 is provided with four locating slots 6, the cross section of locating slot is curved, aluminum core periphery is provided with four positioning boss 7 coordinated with locating slot 6, aluminum core 3 and the inner ring matched in clearance of annular boss 5, it is filled with high-temperature plastic between aluminum core and endoporus；
The periphery, two ends of aluminum core 3 is provided with annular breach 30, it is provided with ring baffle 8 in annular breach 30, ring baffle and endoporus matched in clearance, between the bottom of annular breach, it is provided with some circumferentially distributed connection through holes 31 on aluminum core 3, ring baffle is provided with the connecting hole corresponding with connecting through hole, is connected by bolt 9, nut 10 between ring baffle with aluminum core.
It is connected by high-temperature plastic again after being coordinated by locating slot, positioning boss between emery wheel body with aluminum core, it is ensured that between the circumference of emery wheel body and aluminum core, stable connection, nothing relatively rotate；Ring baffle is positioned at the both sides of annular boss, the axial limiting to emery wheel body, it is ensured that without relative movement between the axial and aluminum core of emery wheel body；The material of emery wheel body reduces, and reduces manufacturing cost, and overall weight alleviates, and reduces vibrations, and stability significantly improves.
