To achieve the above object, the utility model provides a kind of positioner at cylinder block cylinder holes center, including:Positioning
Seat, it is the tubular of one end open, and perisporium offers dowel hole respectively in different height;Top cover, its lid are located at the positioning
In the one end open of seat, the center of the top cover offers screw rod perforation;Screw rod, what it can rotate is located in the top cover center
Screw rod perforation in, and stretch into the positioning seat and be vertically arranged;Mandrel, it is multiple, is respectively provided with axial threaded hole, between distinguishing
Every being screwed on the different height of screw rod, the periphery of the mandrel is tapered slope;And alignment pin, it is multiple, is worn respectively
In the dowel hole of the different height of the positioning seat perisporium, the inner of the alignment pin is contra bevel structure, with the mandrel
The tapered slope of periphery forms wedge pushing structure.
Preferably, in above-mentioned technical proposal, dowel hole opens up along the radial direction of positioning seat.
Preferably, in above-mentioned technical proposal, screw rod includes:Head, rotary shaft and screw shaft are screwed, the screw rod passes through rotation
What axle can rotate is located in the screw rod perforation in top cover center, and the outside for screwing head and being located at top cover, the screw shaft erects
Directly it is arranged in positioning seat, is easy to screw head drive screw rod rotation by spanner.
Preferably, in above-mentioned technical proposal, mandrel is two, and the alignment pin is two layers.
Compared with prior art, the utility model has the advantages that:The positioner at the cylinder block cylinder holes center
The transverse shifting of the alignment pin of one group of different height is respectively controlled by multiple mandrels, to position two different height cylinder block cylinder holes
Center, positioner need not both be changed also without the requirement for installing pad satisfaction processing different height cylinder block additional by reaching.
Brief description of the drawings
Fig. 1 is the overlooking the structure diagram of the positioner at cylinder block cylinder holes center of the present utility model.
Fig. 2 is the cross section structure diagram of the positioner at cylinder block cylinder holes center of the present utility model.
Embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality
New protection domain is not limited by embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members
Part or other parts.
As depicted in figs. 1 and 2, according to the positioner at the cylinder block cylinder holes center of the utility model embodiment
Specifically include:Top cover 1, screw rod 2, alignment pin 3, mandrel 4 and positioning seat 5.Wherein, positioning seat 5 be one end open tubular, perisporium
Dowel hole is offered respectively in different height.The lid of top cover 1 is located in the one end open of positioning seat 5, is formed and is accommodated screw rod 2, determines
Position pin 3, the accommodating chamber of mandrel 4.Screw rod 2 is vertically arranged in positioning seat 5 through top cover 1, and mandrel 4 is multiple, and interval is screwed to
On the different height of screw rod 2.Alignment pin 3 is multiple, in the dowel hole for the different height for being located in the perisporium of positioning seat 5 respectively,
The inner of alignment pin 3 forms wedge pushing structure with the periphery of mandrel 4, and rotary screw 2 makes the mandrel 4 of different height in screw rod 2
Move up and down, the transverse shifting of alignment pin 3 is promoted by mandrel 4, after pin 3 to be positioned is adjacent to cylinder holes circumferential surface, locking.Due to more
The cylinder block cylinder holes center of the corresponding a variety of different heights of individual alignment pin 3, so as to ensure that need not change positioner is also not required to
Install the requirement that pad meets processing different height cylinder block additional.
Specifically, positioning seat 5 is the tubular of one end open, and perisporium offers dowel hole respectively in different height.Top
The lid of lid 1 is located in the one end open of positioning seat 5, is formed and is accommodated screw rod 2, alignment pin 3, the accommodating chamber of mandrel 4.The center of top cover 1
Screw rod perforation is offered, for wearing screw rod 2.
Preferably, radial direction of the dowel hole along positioning seat 5 opens up.
Screw rod 2 includes:Screw head, rotary shaft and screw shaft.Screw rod 2 is located in top cover 1 by what rotary shaft can rotate
In the screw rod perforation in center, the outside that head is located at top cover 1 is screwed, screw shaft is vertically arranged in positioning seat 5, is easy to pass through spanner
Screwing head drives screw rod 2 to rotate so that the mandrel 4 of different height moves up and down in screw rod 2, and then is promoted by mandrel 4
The transverse shifting of alignment pin 3.
Mandrel 4 is multiple, has axial threaded hole, is respectively separated and is screwed on the different height of screw rod 2.Outside mandrel 4
Week is tapered slope.Alignment pin 3 is multiple, in the dowel hole for the different height for being located in the perisporium of positioning seat 5 respectively, alignment pin
3 the inner is contra bevel structure, and for forming wedge pushing structure with the tapered slope of the periphery of mandrel 4, rotary screw 2 makes difference
The mandrel 4 of height moves up and down in screw rod 2, promotes the transverse shifting of alignment pin 3 by mandrel 4, pin 3 to be positioned is adjacent to cylinder holes circumference
Behind surface, locking., need not so as to ensure that due to the cylinder block cylinder holes center of the corresponding a variety of different heights of multiple alignment pins 3
Positioner is changed also without the requirement for installing pad satisfaction processing different height cylinder block additional.
Preferably, mandrel 4 is two, and alignment pin 3 is two layers, corresponds to the different cylinders of cylinder block to be positioned of two kinds of height respectively
Hole center.
To sum up, the positioner at the cylinder block cylinder holes center respectively controls the alignment pin of one group of different height by multiple mandrels
Transverse shifting, to position two different height cylinder block cylinder holes centers, reach need not both change positioner also without
Install the requirement that pad meets processing different height cylinder block additional.
The foregoing description to specific illustrative embodiment of the present utility model is to illustrate and the purpose of illustration.These
Description is not wishing to for the utility model to be defined to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can carry out
