For the deficiency that prior art exists, the purpose of this utility model be to provide a kind of reasonable in design, structure simple, connect reliable, simple load and unload gear grinding fixture.
For achieving the above object, the utility model provides following technical scheme: a kind of gear grinding fixture, comprise expansion set axle, gear and expansion set, described expansion set axle upper surface integral middle is provided with taper shaft, and taper shaft outside wall surface is provided with external screw thread, the endoporus internal face of described expansion set is provided with the internal taper of mating with taper shaft, described taper shaft lower end is socketed with hex nut, and the internal thread of hex nut coordinates formation to be threaded with the external screw thread of taper shaft outside wall surface, described hex nut is socketed with pallet, taper shaft is positioned at hex nut top position and is socketed with thrust disc, taper shaft is positioned at thrust disc top position socket gear, taper shaft is positioned at gear top position socket expansion set, taper shaft is positioned at expansion set top position and has been threaded clamp nut, by clamp nut, expansion set is pressed in the endoporus of gear, thus make expanding cover locking gear.
By adopting technique scheme, expansion set is pressed into the endoporus of gear under the axial compressive force of clamp nut, simultaneously expansion set distending locking gear under tapering effect, it is little that gear and expansion set axle assemble post gap, ensure that the axiality of gear and expansion set axle.Reasonable in design, structure are simple, connection is reliable.
The utility model is set to further: the cross section of the endoporus of described pallet is hexagon, the spacing clamping of endoporus of described hex nut and pallet, pallet drives hex nut to rotate, make hex nut upwards promote promotion thrust disc to move upward, thus make thrust disc expansion set be ejected outward the endoporus of gear.By this setting, structural design is more reasonable, and assembly and disassembly operations is convenient.
The utility model is also set to further: described pallet lower end is provided with connecting portion, and connecting portion is provided with hexagon limit.By this setting, connecting portion is arranged rationally, connects convenient.
The utility model is also set to further: described thrust disc is positioned at the endoporus of pallet, and the diameter of thrust disc is less than the large footpath of hex nut.By this setting, structure is more reasonable, connects convenient.
The utility model is also set to further: described pallet lower surface is connected with expansion set axle upper surface, and pallet upper surface is connected with the lower surface of gear.By this setting, connect convenient.
The utility model has the advantages that: compared with prior art, the utility model vibrational power flow is reasonable, expansion set is pressed into the endoporus of gear under the axial compressive force of clamp nut, expansion set distending locking gear under tapering effect simultaneously, it is little that gear and expansion set axle assemble post gap, ensure that the axiality of gear and expansion set axle; Pallet drives hex nut to rotate, and makes hex nut upwards promote promotion thrust disc and moves upward, thus make thrust disc expansion set be ejected outward the endoporus of gear.Reasonable in design, structure are simple, connection is reliable, mounting or dismounting are convenient.
Below in conjunction with Figure of description and specific embodiment, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
See Fig. 1, a kind of gear grinding fixture disclosed in the utility model, comprise expansion set axle 1, gear 2 and expansion set 3, described expansion set axle 1 upper surface integral middle is provided with taper shaft 11, and taper shaft 11 outside wall surface is provided with external screw thread, the endoporus internal face of described expansion set 3 is provided with the internal taper of mating with taper shaft 11, described taper shaft 11 lower end is socketed with hex nut 4, and the internal thread of hex nut 4 coordinates formation to be threaded with the external screw thread of taper shaft 11 outside wall surface, described hex nut 4 is socketed with pallet 5, taper shaft 11 is positioned at hex nut 4 top position and is socketed with thrust disc 6, taper shaft 11 is positioned at thrust disc 6 top position socket gear 2, taper shaft 11 is positioned at gear 2 top position socket expansion set 3, taper shaft 11 is positioned at expansion set 3 top position and has been threaded clamp nut 7, by clamp nut 7, expansion set 3 is pressed in the endoporus of gear 2, thus make expansion set 3 locking gear 2.
For making the utility model structure more reasonable, as preferably, described in the present embodiment, the cross section of the endoporus of pallet 5 is hexagon, the spacing clamping of endoporus of described hex nut 4 and pallet 5, pallet 5 drives hex nut 4 to rotate, make hex nut 4 upwards promote promotion thrust disc 6 to move upward, thus make thrust disc 6 that expansion set 3 is ejected the endoporus of gear 2 outward.
Described pallet 5 lower end is provided with connecting portion 51, and connecting portion 51 is provided with hexagon limit.
Described thrust disc 6 is positioned at the endoporus of pallet 5, and the diameter of thrust disc 6 is less than the large footpath of hex nut 4.
Described pallet 5 lower surface is connected with expansion set axle 1 upper surface, and pallet 5 upper surface is connected with the lower surface of gear 2.
During practical application, expansion set is pressed into the endoporus of gear under the axial compressive force of clamp nut, simultaneously expansion set distending locking gear under tapering effect, it is little that gear and expansion set axle assemble post gap, ensure that the axiality of gear and expansion set axle; Unscrew clamp nut during taking-up, block the connecting portion turn pallet of pallet bottom with spanner, pallet drives hex nut to rotate, and makes hex nut upwards promote promotion thrust disc and moves upward, thus make thrust disc expansion set be ejected outward the endoporus of gear.Reasonable in design, structure are simple, connection is reliable, mounting or dismounting are convenient.
