Embodiment
Referring to Fig. 1, Fig. 2, the utility model provides a kind of water pump pump case clamping and risen core, including in body 1, described
Body 1 includes bottom plate 2, is arranged on the support tube 3 being superimposed upwards successively, the guide cylinder 4 of the top surface of bottom plate 2, the external diameter of the guide cylinder 4
Less than the external diameter of support tube 3；Through hole is through with the bottom surface of top surface to the bottom plate 2 of guide cylinder 4（Do not marked in figure）；The guide cylinder
Clamp system is arranged with 4, it is in the tensioner rubber ring 5 and clamp sleeve 6 being superimposed up and down that the clamp system, which includes at least two groups,
Clamp sleeve 6 is in the top of tensioner rubber ring 5；The top surface of clamp sleeve 6 in the top is higher than the top surface of guide cylinder 4,
Briquetting 7 is placed with the top surface of clamp system, the center of the briquetting 7 is provided with mounting hole（Do not marked in figure）, the mounting hole（Figure
In do not mark）With through hole（Do not marked in figure）Center line be conllinear；The bottom surface of the bottom plate 2 is provided with cylinder 8, the piston of cylinder 8
The axis and through hole of bar 9（Do not marked in figure）Centerline collineation, bolt 10 sequentially passes through mounting hole（Do not marked in figure）, through hole（Figure
In do not mark）It is spirally connected and is fixed on the screw of the end of piston rod 9（Do not marked in figure）It is interior；When piston rod 9 moves down, bolt 10 drives briquetting 7
Extruding clamp system is moved down, tensioner rubber ring 5 is expanded outwardly by compression, so as to clamp water pump pump housing endophragm；When on piston rod 9
Move, tensioner rubber ring 5 recovers deformation, so as to lose the expanding force to water pump pump housing endophragm.
The center of tensioner rubber ring 5 is provided with annular core 11.
Do not stressed in tensioner rubber ring 5 under state, the top surface of top surface to the guide cylinder 4 of the clamp system be smaller than or
Equal to the summation of the largest deformation distance of multiple tensioner rubber rings 5.
If the outer wall of the guide cylinder 4 is provided with dry sump 12.
The external diameter of the clamp sleeve 6 is consistent with the external diameter of support tube 3.
Water pump pump case of the present utility model is made an explanation with the operation principle for clamping the core that rises below：
Water pump pump case clamping of the present utility model is risen core, and when not working, tensioner rubber ring 5 is in the state that do not stress,
Now, the external diameter of tensioner rubber ring 5 is consistent with the external diameter of clamp sleeve 6, when needing to clamp water pump pump case, first by water pump pump case
It is enclosed on clamp system, the processing external diameter of clamp sleeve 6 is slightly less than the internal diameter of pump housing endophragm, so, only needs less deformation just
Pump case can be clamped, and obtains preferable clamping effect, then, cylinder 8 drives piston rod 9 to move down, due to the hexagonal of bolt 10
Head is pressed on briquetting 7 and bolt 10 is screwed onto on piston rod 9, and so, piston rod 9 drives bolt 10 to move down vertically, then makes
Briquetting 7 moves down, and briquetting 7, which moves down, drives the clamp sleeve 6 being close to briquetting 7 to move down, and tensioner rubber ring 5 is in two clamp sleeves
Between 6, so, the clamp sleeve 6 of top gives tensioner rubber ring 5 one downward pressure, and in the lower section of tensioner rubber ring 5
Clamp sleeve 6 is formed the tensioner rubber ring 5 of a direction active force upward, tensioner rubber by the pressure transmission of top
Circle 5 is finally produced deformation, led because tensioner rubber ring 5 is set in by the opposite active force of two adjacent clamp sleeves 6
To the outer wall of cylinder 4, so, the inside deformation direction of tensioner rubber ring 5 is limited, and can only radially expand, after expansion
The external diameter of tensioner rubber ring 5 be more than pump case internal diameter, so as to outwardly against pump case and step up pump case, due to tensioner rubber ring 5
For quality of rubber materials, can be good at protecting pump case injury-free, in addition, just right expanding force, can avoid pump case
Deformation, cause pump case can not normal use, even if the deformation of tensioner rubber ring 5 is excessive, due to flexible deformation, tensioner rubber ring
5 are limited by pump housing endophragm, and the tensioner rubber ring 5 for being close to pump housing inwall lower vertically can then extend, to a certain degree
On avoid due to the excessive influence brought to pump case of stress, also avoid to a certain extent pump case deformation situation occur.
In order to avoid the excessively caused reduced lifetime problem of deformation caused by stress is too quickly of tensioner rubber ring 5 occurs, this practicality is new
Type provides two kinds of solutions：First, in the centrally disposed annular core 11 of tensioner rubber ring 5, tensioner rubber ring 5 is extended
Service life；2nd, the top surface of clamp system is made to the top surface line space design of guide cylinder 4 into less than or equal to multiple tensioner rubber
Circle 5 largest deformation distance summation, so, no matter piston rod 9 pulling force it is much, the largest deformation of multiple tensioner rubber rings 5
Distance is definite value, avoids the excessive situation of the deformation of tensioner rubber ring 5 and occurs, so as to extend its service life.
In addition, the design of the outer wall oil groove 12 of guide cylinder 4, reduces the frictional force between clamp sleeve 6 and guide cylinder 4, prolongs
Long life.
A kind of water pump pump case provided above the utility model embodiment is described in detail with the clamping core that rises, this
Apply specific case in text to be set forth principle of the present utility model and embodiment, the explanation of above example is
It is used to help understand the technical scheme disclosed in the utility model；Meanwhile for those of ordinary skill in the art, according to this reality
With new thought, there will be changes in specific embodiments and applications, in summary, this specification content is not
It is interpreted as limitation of the present utility model.
