In
aforesaid more piece circle plug gear anchor clamps, be uniformly distributed with the pitch radius that three groups of radiuss of a circle described in the through hole equal gear on the said annulus along the circumference.
In
aforesaid more piece circle plug gear anchor clamps, said three groups of through holes, every group comprises 2～5 through holes, and every group number of openings equates, the spacing in every group between the two through hole equals the tooth pitch of gear.
In
aforesaid more piece circle plug gear anchor clamps, the internal diameter of said elastic clamping collar is corresponding with the outside circle of gear.
In
aforesaid more piece circle plug gear anchor clamps, the interior circle of two adjacent teeth side and elastic clamping collar is tangent on the cylindrical of said pitch circle plug and the gear.
In
aforesaid more piece circle plug gear anchor clamps, said elastic clamping collar is provided with three elastic grooves, and three elastic grooves are radial along the elastic clamping collar circumference uniform distribution.
In
aforesaid more piece circle plug gear anchor clamps, said three elastic grooves and three groups of through holes are provided with at interval.
In
aforesaid more piece circle plug gear anchor clamps, the barrel and the annulus of said three elastic grooves and three groups of through hole perforation elastic clamping collars, the bottom land of elastic groove on annulus is arcuate bottom.
compared with prior art, the improper gear shifting quadrant texturing problem that causes of clamping when the utility model can solve Gear Processing.Easy to adjust when clamping, saving of work and time; Needn't reserve more allowance during the gear preliminary working, and can remedy the influence of gear heat treatment deformation, it is quick to have convenient mounting and clamping, and production efficiency is high, is applicable to the production in enormous quantities of thin-walled gear.The utility model is simple in structure, use is reliable.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the utility model and the sketch map that cooperates of gear.
Being labeled as in
accompanying drawing: 1-elastic clamping collar, 2-pitch circle plug, 3-screwed hole, 4-annulus, 5-through hole, 6-screw, 7-gear, 8-elastic groove, 9-arcuate bottom.
The specific embodiment
are further described the utility model below in conjunction with accompanying drawing and embodiment, but not as the foundation to the utility model restriction.
embodiment.A kind of more piece circle plug gear anchor clamps, as shown in Figure 1, comprise elastic clamping collar 1 and pitch circle plug 2; Pitch circle plug 2 one ends are provided with screwed hole 3 (see figure 2)s; Elastic clamping collar 1 is a tubular structure, and an end of tubular is connected with annulus 4, is uniformly distributed with three groups of through holes 5 on the annulus 4 along the circumference, and each through hole 5 is connected with pitch circle plug 2 through screw 6.Be uniformly distributed with three groups of radiuss of a circle described in the through hole 5 on the annulus 4 along the circumference and equal the pitch radius of gear 7.Three groups of through holes 5, every group comprises 2～5 through holes, and every group number of openings equates, the spacing in every group between the two through hole equals the tooth pitch of gear 7.The internal diameter of elastic clamping collar 1 is corresponding with the outside circle of gear 7.The interior circle of two adjacent teeth side and elastic clamping collar 1 is tangent on the cylindrical of pitch circle plug 2 and the gear 7.It is radial along elastic clamping collar 1 circumference uniform distribution that elastic clamping collar 1 is provided with 8, three elastic grooves of three elastic grooves 8.Article three, elastic groove 8 and three groups of through holes 5 are provided with at interval.Elastic groove 8 connects the barrel and the annulus 4 of elastic clamping collar 1, and the bottom land of elastic groove 8 on annulus 4 is arcuate bottom 9.
