Abstract
The utility model provides a kind of eccentric shaft part to adjust location structure, comprises an eccentric shaft part, an axle sleeve, number stop block and counts spiral shell and establish part, and concrete structure is as follows.Eccentric shaft part is concaved with respectively groove in two ends, form flange with respect to groove; The corresponding sheathed eccentric shaft part of axle sleeve, the groove place of the corresponding eccentric shaft part of portion is provided with interior caulking groove in the inner, and is provided with perforation in interior caulking groove; Number stop blocks have and wear the sleeve sections of interior caulking groove perforation and be embedded at the section of pulling of supporting in interior caulking groove, and sleeve sections has internal thread; Number spiral shells are established part correspondence and lock the internal thread of the sleeve sections of stop block, and corresponding support to pull be packed in eccentric shaft part groove.The utility model is adjusted convenient fixing, simultaneously the processing of convenient entirety.
Description
Technical field
The utility model relates to a kind of eccentric shaft part and adjusts location structure, belongs to mechanical engineering field.
Background technology
Eccentric shaft part correspondence is assembled in belt pulley or the chain wheel in mechanical engineering, carrys out interlock with belt, chain.Its both sides of known eccentric shaft part have chase, eccentric shaft part correspondence is sheathed in an axle sleeve, in two ends, corresponding chase place is provided with perforation to axle sleeve, be welded with the projection of tool screw fixed hole in perforation place, the screw fixed hole place correspondence of projection is locked a double-screw bolt, establishes the chase place of eccentric shaft part and is positioned eccentric shaft part with double-screw bolt lock.In its manufacturing process, need first the projection of tool screw fixed hole to be machined, the more corresponding procedure with welding is located at corresponding projection weldering on axle sleeve, therefore, increased the formality of manufacturing process, and welding processing comparatively time-consuming and trouble and adjust location also inconvenience, part really haves much room for improvement.
Summary of the invention
In order to overcome defect of the prior art, the utility model provides a kind of eccentric shaft part to adjust location structure.
The utility model solves the technical scheme that its technical problem adopts: the utility model provides a kind of eccentric shaft part to adjust location structure, comprises that an eccentric shaft part, an axle sleeve, number stop block and number spiral shell establish part, and concrete structure is as follows.
Eccentric shaft part is concaved with respectively groove in two ends, form flange with respect to groove; The corresponding sheathed eccentric shaft part of axle sleeve, the groove place of the corresponding eccentric shaft part of portion is provided with interior caulking groove in the inner, and is provided with perforation in interior caulking groove; Number stop blocks have and wear the sleeve sections of interior caulking groove perforation and be embedded at the section of pulling of supporting in interior caulking groove, and sleeve sections has internal thread; Number spiral shells are established part correspondence and lock the internal thread of the sleeve sections of stop block, and corresponding support to pull be packed in eccentric shaft part groove.
The beneficial effects of the utility model are: adjust convenient fixing, simultaneously the processing of convenient entirety.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is overall decomposing schematic representation of the present utility model.
Fig. 2 is adjustment schematic diagram one of the present utility model.
Fig. 3 is adjustment schematic diagram two of the present utility model.
Detailed description of the invention
As shown in Figure 1 to Figure 3, the utility model provides a kind of eccentric shaft part to adjust location structure, comprises an eccentric shaft part 1, an axle sleeve 2, number stop block 3 and counts spiral shell and establish part 4, and concrete structure is as follows.
Eccentric shaft part 1 is concaved with respectively groove 5 in two ends, form flange 6 with respect to groove.
The corresponding sheathed eccentric shaft part 1 of axle sleeve 2, groove 5 places of the corresponding eccentric shaft part 1 of portion are provided with interior caulking groove 7 in the inner, and are provided with perforation 8 in interior caulking groove 7.
Number stop blocks 3 have and wear bore a hole 8 sleeve sections 9 and be embedded at and support the section of pulling 10 in interior caulking groove 7 of interior caulking groove 7, and sleeve sections 9 has internal thread 11.
Number spiral shells are established part 4 correspondences and lock the internal thread 11 of the sleeve sections 9 of stop block 3, and corresponding support to pull be packed in eccentric shaft part 1 groove 5.
When use, the clutch end correspondence of eccentric shaft part 1 is assembled in belt pulley or chain wheel (not shown), carrys out interlock with belt, chain.First, interior caulking groove 7 places in axle sleeve 2 embed stop block 3, make the sleeve sections 9 of stop block 3 wear interior caulking groove 7 and bore a hole 8, be embedded in interior caulking groove 7 and support the section of pulling 10, embed in axle sleeve 2 corresponding eccentric shaft part 1 again, and the position that adjustment and axle sleeve 2 internal diameters are suitable, the difference of its position can affect belt, the elasticity of chain, allow the interior caulking groove 7 of the corresponding axle sleeve 2 of groove 5 of eccentric shaft part 1, stop block 3 is butted on flange 6 places of eccentric shaft part 1 to the section of pulling 10 inner sides, spiral shell is established to part 4 correspondences again and is locked the internal thread 11 of the sleeve sections 9 of stop block 3, and correspondence is supported to pull and is packed in eccentric shaft part groove 5.Whereby, reach firm safe locating effect, and adjust convenient fixing, the processing of convenient entirety simultaneously.Need adjust time, as long as pine move back spiral shell establish part 4 eccentric shaft part 1 can be rotated slightly adjustment angle, make its relative wheelbase difference, to adjust the elasticity of belt, chain.
