In figure: 1 fixed disk, 11 taper installing holes, 12 annular compensating grooves, 2 emery wheels, 21 gaps, 3 screw shells, 31 tightening screwed holes, 32 adjustment screwed holes, 4 holding screws, 5 adjustment plates, 6O type circle, 7 threaded adjustment bars.
Detailed description of the invention
By reference to the accompanying drawings, specific embodiments of the invention are described.
As shown in Figure 1: standard design M7475B emery wheel fastener comprises emery wheel fixed disk 1, emery wheel 2 forms, wherein M7475B is the code name of vertical circular table surface grinder.
As shown in accompanying drawing 2-accompanying drawing 6: M7475B emery wheel fastener of the present invention, comprise emery wheel fastening disk assembly, emery wheel 2, threaded adjustment bar composition.Emery wheel fastening disk assembly is made up of fixed disk 1, screw shell 3, holding screw 4, adjustment plate 5, O type circle 6.Screw shell circumference be provided with the tightening screwed hole 31 that is in different section place and four along uniform adjustment screwed hole 32, five tapped bores of its circumference and pitch identical.Threaded adjustment bar 7 quantity is four, and left side is lever operated portion, and right side screw thread coordinates with the adjustment screwed hole 32 on screw shell.
As can be seen from structure above, the M7475B emery wheel fastener of the present invention's design: fixed disk 1 inside diameter surface is taper surface, form taper installing hole 11, taper installing hole 11 bottom inner diameter is consistent with the outside dimension of emery wheel, ensure that the accuracy of alignment of new clothes emery wheel, partially be outside equipped with compensating groove 12 in fixed disk upper surface simultaneously, can further to the accurate balanced adjustment of emery wheel, annular compensating groove 12 partially in position fixed disk on be provided with the threaded mounting hole of eight uniform M12, fixed disk can be connect with electric machine main shaft disk.Screw shell 3 internal diameter and fixed disk 1 external diameter are for having the spiral marking connection of " self-locking " function, the adjustment screwed hole 32 of a tightening screwed hole 31 and four circumference uniform distributions is provided with in screw shell 3 circumference, for simplified design and installation, five tapped bores and pitch identical.As shown in Figure 3, during new clothes emery wheel, fixed disk 1 and screw shell 3 connect, and two adjustment plates 5 carry out spiral marking connection with screw shell 3, and the pressure relying on adjustment plate 5 to screw in makes O type circle 6 be out of shape, and makes emery wheel 2 become to be integrated with whole fastener.Adjustment plate 5 screws rear adjustment screw shell 3 position, loads holding screw 4, prevents the unintentional rotation of screw shell 3 in process.As shown in Figure 4, when abrasion of grinding wheel is to screw shell lower surface close to Fig. 3, unclamp holding screw 4, utilize four threaded adjustment bars 7 to be rotated up by screw shell 3, when the upper surface of screw shell 3 and fixed disk 1 upper surface close to time, adjustment plate 5 bottom can disengage threads sleeve 3, after fine setting screw shell 3, load holding screw 4, now, one of them in four adjustment screwed holes 32 can become set screw hole temporarily.Along with screw shell 3 moving the disengagement with the adjustment plate 5 of bottom, emery wheel 2 can utilize a period of time again, in sum, emery wheel fastener provided by the invention have emery wheel can automatic centering, to operation lathe personnel's health and environment without endangering, emery wheel can make full use of, the advantage such as cost-saving.
