Abstract
The utility model discloses a kind of stopping means of the printer axis of guide, comprise the axis of guide, bearing and cover plate, the described axis of guide is fixed in the fixing hole of printer side plate by described bearing, described cover plate is fixed on the side of the fixing hole of described printer side plate, described cover plate being provided with several for inserting the through hole of limited post, after limited post inserts described through hole, limiting the axial displacement of described bearing with the surface contact of fixing hole middle (center) bearing; Described limited post is fastening by the fastener and described cover plate embedding cover plate.The utility model inserts in the through hole on cover plate by limited post, and with the surface contact of printer side plate fixing hole middle (center) bearing, limited post is fastening by fastener again, the axial displacement of bearing can be limited, meanwhile, in the fastener cycle of cover plate, limited post can not apply pressure to bearing, cause bearing deformation, dystopy, can not impact the inherent variability of bearing, ensure axis of guide smooth movements.
Description
Technical field
The utility model belongs to printer technology field, particularly relates to the syndeton of the axis of guide and printer side plate in printer.
Background technology
At assembling printer, when the axis of guide is installed, need the perforate of guarantee two side plates as far as possible accurate, the coaxial bearing at axis of guide two ends, the smooth rotation of such guarantee axis of guide, but due to the error of machining accuracy and assembly precision, inherently cause inevitable deviation between axis of guide spindle nose and side plate fixing hole, guiding spindle nose is fixed in side plate fixing hole by bearing, thus bearing also inevitably can produce deviation, this deviation is acceptable, can not have influence on the normal rotation of the axis of guide.On the other hand, in use, also need to carry out spacing to bearing, prevent axis of guide play vertically in a device, current limit method is: bearing is carried out Limit Bearing by the cover plate that side plate both sides are fixing.Existing limit method is in the fastener cycle of cover plate, due to the reason such as deviations from planarity of cover plate self, bearing can be caused to be subject to cover plate pressure distortion, or revise the deviation that bearing produces in installation process by force, the further rotation affecting the axis of guide, makes the axis of guide run not smooth.
Summary of the invention
Goal of the invention: the utility model object is for the deficiencies in the prior art, provides a kind of stopping means that can not affect the printer axis of guide that the axis of guide runs while spacing.
Technical scheme: the stopping means of the printer axis of guide described in the utility model, comprise the axis of guide, bearing and cover plate, the described axis of guide is fixed in the fixing hole of printer side plate by described bearing, described cover plate is fixed on the side of the fixing hole of described printer side plate, described cover plate being provided with several for inserting the through hole of limited post, after limited post inserts described through hole, limiting the axial displacement of described bearing with the surface contact of fixing hole middle (center) bearing; Described limited post is fastening by the fastener and described cover plate embedding cover plate.
As preferably, described cover plate is two, is separately fixed at the two sides of printer wherein side side plate.
As preferably, described cover plate is two, is separately fixed at opposite side or the phase dorsal part of printer both sides side plate.
As preferably, described cover plate is four, is separately fixed at the both sides of described printer both sides side plate.
As preferably, the described axis of guide is provided with limited block, for limiting the axial displacement of described bearing on the axis of guide.
As preferably, described limited block is bearing shoulder block, axle card or bearing locating part.
As preferably, described limited post is by inserting cover plate and the set bolt vertical with described limited post is fastening.
Beneficial effect: (1) the utility model inserts in the through hole on cover plate by limited post, and with the surface contact of printer side plate fixing hole middle (center) bearing, limited post is fastening by fastener again, the axial displacement of bearing can be limited, meanwhile, in the fastener cycle of cover plate, limited post can not apply pressure to bearing, cause bearing deformation, dystopy, can not impact the inherent variability of bearing, ensure axis of guide smooth movements; (2) when the utility model cover plate is two, be separately fixed at opposite side or the phase dorsal part of printer both sides side plate, or be separately fixed at the two sides of printer wherein side side plate, can guarantee that bearing all there will not be on the both sides of axial direction and be subjected to displacement; (3) the utility model is provided with limited block on the axis of guide, the axial displacement of restriction bearing on the axis of guide, adopt the two sides mode of fixing side side plate, an other side bearing does not fix in the fixing hole of side plate, can be the axis of guide in the course of the work, the change caused owing to expanding with heat and contract with cold leaves extendable room.
Accompanying drawing explanation
Fig. 1 is the structural representation of the stopping means of the printer axis of guide described in the utility model;
Fig. 2 is the structural representation of cover plate described in the utility model.
Detailed description of the invention
Below by accompanying drawing, technical solutions of the utility model are described in detail, but protection domain of the present utility model is not limited to described embodiment.
Embodiment 1: a kind of stopping means of the printer axis of guide, comprise the axis of guide 1, bearing 2 and four cover plates 3, the described axis of guide 1 is fixed in the fixing hole of printer side plate 4 by described bearing 2, described cover plate 3 is separately fixed at the fixing hole two sides of printer side plate 4, described cover plate 3 is provided with several for inserting the through hole of limited post 5, limited post 5 inserts the surface contact with fixing hole middle (center) bearing 2 after described through hole, limits the axial displacement of described bearing 2; Described limited post 5 is by insertion cover plate and the set bolt 6 vertical with described limited post is fastening.
As mentioned above, although represented with reference to specific preferred embodiment and described the utility model, it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model not departing from claims definition, various change can be made in the form and details to it.
