The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.
As shown in Figures 1 to 4, a kind of miniature abrasive band of the present invention tool grinder device comprises base 1, driving wheel 16 and driven pulley 6, and base 1 is the monoblock cast part, can improve the rigidity of member, driving wheel 16 is installed on the macro-axis 4, and macro-axis 4 two ends are provided with large axle bearing 3, and macro-axis 4 is installed on the base 1 by bearing base 2, driven pulley 6 is installed on the little axle 9, little axle 9 two ends are provided with little axle bearing 8, and little axle bearing 8 is installed in the axis hole of base 1 reservation, and little axle 9 ends are provided with little hubcap 7.Wherein, large axle bearing 3, little axle bearing 8 and tension wheel shaft bearing 12 are 6202 type rolling bearings or can bear arbitrarily the member of this effect.Driving wheel 16 is connected with driven pulley by abrasive band 5 connections, be provided with the regulating wheel system between driven pulley 6 and the driving wheel 16, the regulating wheel system comprises the skewed slot that base 1 side is provided with, spring 11, tension pulley support 13, regulating wheel 15, the logical skewed slot of skewed slot for offering in the side of body base 1, be used for installing tension pulley support 13, tension pulley support 13 is installed tension wheel shaft 14, regulating wheel 15 is installed on the tension wheel shaft 14, be provided with tension wheel shaft bearing 12 between regulating wheel 15 and the tension wheel shaft 14, the skewed slot upper end is provided with lead 10, spring 11 is on the space between base 1 and the tension pulley support 13, spring 11 1 ends contact with tension pulley support 13, and spring 11 other ends connect lead 10.
In the present embodiment, spring 11 has two, and lead 10 has two, and the angle α of skewed slot and horizontal plane is 30 °～45.Tension wheel shaft 14 is installed in the axis hole on the tension pulley support 13, tension wheel shaft 14 two ends are processed with screw thread, adjust tension wheel shafts 14 and lock it on the tension pulley support 13 by nut 17, regulating wheel 15 is installed on the tension wheel shaft 14, between regulating wheel 15 and the tension wheel shaft 14 tension wheel shaft bearing 12 is installed.Regulating wheel 15 rotates around tension wheel shaft 14 by tension wheel shaft bearing 12, and tension wheel shaft 14 is fixed on the tension pulley support 13, does not do gyration.
In the present embodiment, abrasive band 5 is installed on driving wheel 16, driven pulley 6 and the regulating wheel 15, utilizes the compressed active force abrasive band tensioning degree that automatically adjusts that produces of regulating wheel system deadweight component and spring 11.When the active force on abrasive band 5 changes, change the active force that telescopic level comes balance abrasive band 5 by spring 11; To such an extent as to 5 vibrations that produce when rotating also can absorb and reduce to eliminate unnecessary vibration by spring 11 in the abrasive band; Stuck in skewed slot the time at tension pulley support 13, also can change by spring 11 state of tension pulley support 13, guarantee the suitable tensioning degree in abrasive band 5, thereby guarantee the quality of surface to be machined.
Specifically, in the present invention, produced the acting in conjunction of component and the spring 11 compressed active forces that produce of regulating wheel system own wt by the groove of skewed slot to the angle, can be applied certain tensile force to abrasive band 5, so just played the regulating action to abrasive band 5 tensionings.During work, driving wheel 16 is worked under the traction of motor, passes motion to driven pulley 6 and regulating wheel 15 by abrasive band 5, drives driven pulley 6 and regulating wheel 15 and does gyration.When the power on the abrasive band 5 changes when causing the fluctuation of abrasive band 5 tensile forces, principle according to active force and reaction force, stressedly on the regulating wheel 15 also can change, so when running into that the fluctuation that larger variation produces occurs motor speed or cutting force changes in grinding process, can realize external equilibrium of forces under the acting in conjunction by the component of regulating wheel system own wt and the spring 11 compressed active forces that produce, reduce and absorb unnecessary vibration.Lead 10 is processed with screw thread with the part that body base 1 is connected in addition, can come the tightness of regulating spring 11 by the length of regulating lead 10, thereby plays the effect of regulating the regulating wheel system.In the course of the work, when abrasive band 5 is too lax, because 11 thrust of spring have been tightened abrasive band 5; When too tighten in abrasive band 5, because elastic force and the clamping system Action of Gravity Field of spring 11, so that abrasive band 5 keeps suitable elasticity.The regulating wheel system can regulate automatically according to external force size the degree of tightness in abrasive band 5, does not need artificial adjusting, comes balance external force according to the stressing conditions of reality; too tensioning or abrasive band 5 are too lax to avoid abrasive band 5; protection abrasive band 5, the service life in prolongation abrasive band 5, the quality of assurance surface to be machined.
The above only is preferred embodiment of the present invention; be noted that for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
