Abstract
Disclosed is a dynamic-balance device used for three-point-positioning grinding-wheel detection. The dynamic-balance device includes a dynamic balance shaft and a locknut. The two ends of the dynamic balance shaft are support shafts. Between the two support shafts are, from left to right, a drive pulley, a reference plate, an involute positioning shaft and a threaded shaft with external threads respectively. The threaded shaft is in thread connection with the locknut. The right side face of the reference plate is used as a reference face and the reference face is vertical to the axis of the involute positioning shaft and extends towards an outer edge. The dynamic-balance device used for the detection of the three-point positioning grinding wheel simulates a use process through concentricity in automatic centering of an involute and detects the imbalance state of the grinding wheel accurately. The dynamic-balance device is high in balance precision, great in stability of dynamic balance values and stable in end-jump and circular-jump values and areas of the grinding wheel and the dynamic-balance device.
Description
Technical field
The utility model relates to three-point fix grinding wheel dynamic balance detection technique field, specifically a kind of dynamic poise device detecting for three-point fix emery wheel.
Background technology
Emery wheel is because foozle and the reason of installing on ring flange tend to cause imbalance.Wheel unbalance refers to that the center of gravity of emery wheel does not overlap with rotation center, because emery wheel barycenter departs from due to rotation center.Making wheel balance is all generally in grinding wheel flanged disc ring groove, to load onto a plurality of counterbalance weights, adjusts the position of counterbalance weight, and the center of gravity of emery wheel is overlapped with rotation center, can make wheel balance.Counterbalance weight is different by varying in size of emery wheel, and also there is very big difference in the mechanism of its shape, motion state and control, and this has brought very big inconvenience for manually adjusting balance.
Modern cylindrical grinder improving constantly because of machining precision, collaboration accuracy requirement to emery wheel is increasingly accurate, mostly between emery wheel and grinding machine spindle, adopt three-point fix to detect and be difficult to detect accurately its transient equilibrium value with the transient equilibrium of the accuracy requirement ，Dan emery wheel production firm that guarantees it and coordinate.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of dynamic poise device detecting for three-point fix emery wheel is provided, and can in time understand the non-equilibrium state of emery wheel, and balance quality is high, regulates the speed fast.
Technical solution of the present utility model is as follows:
A kind of dynamic poise device detecting for three-point fix emery wheel, feature is that its formation comprises transient equilibrium axle and set nut, the two ends of described transient equilibrium axle are respectively back shafts, between these two back shafts, be drive pulley, reference disk, involute urve locating shaft from left to right successively and have externally threaded thread spindle, this thread spindle is threaded with described set nut; The right flank of reference disk of take is reference field, and this reference field is vertical with the axis of described involute urve locating shaft, and extends to outer rim.
The periphery of described involute urve locating shaft be by the identical involute urve of three strips join end to end, around forming.
Compared with prior art, technique effect of the present utility model is by concentricity in the automatic capturing of involute urve, simulates use procedure, detects accurately the non-equilibrium state of emery wheel, balance quality is high, transient equilibrium value stabilization is good, the end of emery wheel and this device is jumped and circle is jumped numerical value, regional stability.
Accompanying drawing explanation
Fig. 1 is that the utility model is for the structural representation of the dynamic poise device of three-point fix emery wheel detection.
Fig. 2 is the cut-open view of A-A in Fig. 1.
Fig. 3 is the partial enlarged drawing of B in Fig. 2.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but should not limit protection domain of the present utility model with this.
Please first consult Fig. 1, Fig. 1 is that the utility model is for the structural representation of the dynamic poise device of three-point fix emery wheel detection, as shown in the figure, a kind of dynamic poise device detecting for three-point fix emery wheel, comprise transient equilibrium axle and set nut 4, the two ends of described transient equilibrium axle are respectively back shafts 6, between these two back shafts 6, be drive pulley 1, reference disk 2, involute urve locating shaft 3 from left to right successively and have externally threaded thread spindle 5, this thread spindle 5 is threaded with described set nut 4.The right flank of reference disk 2 of take is reference field, and this reference field is vertical with the axis of described involute urve locating shaft 3, and extends to outer rim.Fig. 2 is the cut-open view of A-A in Fig. 1, Fig. 3 is the partial enlarged drawing of B in Fig. 2, as seen from the figure, the periphery of involute urve locating shaft 3 be by the identical involute urve of three strips join end to end, around forming, its shape, size and the shape of three-point fix emery wheel inner circle to be measured, big or small suitable.
First the job operation of the dynamic poise device that the utility model detects for three-point fix emery wheel is, with Double Tops point location processing transient equilibrium axle, the two ends of this transient equilibrium axle are back shafts 6, are drive pulley 1, reference disk 2, involute urve locating shaft 3 and thread spindle 5 between two back shafts 6 from left to right successively.Then, mill out the groove of involute urve axle 3 by machining center, what this groove take as the center of circle, presents three involute urve shapes.Finally, with Double Tops point location, refine drive pulley 1, reference disk 2 and two back shafts 6 of transient equilibrium axle.
The concrete operation step of the dynamic poise device that the utility model detects for three-point fix emery wheel is as follows:
Step 1, three-point fix emery wheel is vertically placed on transient equilibrium axle;
Step 2, three-point fix emery wheel is moved to thread spindle 5 places, from involute urve low spot, enter involute urve locating shaft 3, three-point fix emery wheel is close on reference disk 2;
Step 3, the emery wheel of holding with a firm grip, along involute urve direction rotation, until three-point fix emery wheel and involute urve locating shaft place 3 clamp mutually;
Step 4, with set nut 4, carry out fastening;
Step 5, by this dynamic poise device of dynamic-balance tester band belt pulley, the unbalanced value region of measuring three-point fix emery wheel, is removed, to reach in standard equilibrium value allowed band.
Before and after using the utility model, three-point fix grinding wheel dynamic balance amount detection index is contrasted as following table:
Although the utility model discloses preferred embodiment as above; so it is not in order to limit content of the present utility model; anyly be familiar with this skill person; within not departing from main spirits of the present utility model and context; when doing various changes and retouching, therefore protection domain of the present utility model should be as the criterion with the basic right claimed range of applying for a patent.
