Embodiment
Further details of narration is carried out to the utility model below in conjunction with accompanying drawing.
As shown in accompanying drawing 1-9, a kind of core positions harness, and it includes bottom plate 1, be fixedly installed on the bottom plate 1 two
To bearing 2, the slide bar being respectively fixedly disposed between bearing 2 described in each pair 3, the slide plate 4 that is slidably arranged on the slide bar 3 with
And the level measurement device on the slide plate 4 is fixedly installed on, the level measurement device includes being fixedly installed on the slide plate 4
Horizontal survey seat 5, the horizontal drafting board 7 that can be slided in the horizontal direction being arranged in the movable span 6 upper and that be provided with movable span 6
And the block 8 at both ends in the movable span 6 is respectively fixedly disposed at, the horizontal upper end of drafting board 7 is provided with to be coordinated with block 8
The locating piece 9 used, is fixedly installed holding rod 10 on the horizontal drafting board 7, it is described it is horizontal survey on seat 5 to be provided with is available for holding rod 10
The chute 11 of slip, the slide plate 4, level measurement device are the moving parts for positioning harness, and slide plate 4 drives level measurement device
Move in the horizontal direction, horizontal drafting board 7 realizes its reciprocating motion under the push-and-pull action of holding rod 10, and block 8 and locating piece 9 are matched somebody with somebody
Close and realize that the position between the second core 18 and the first core 17 positions, horizontal survey seat 5 upper end, which is set, is available for height to position
Groove 12, be provided with height drafting board 13 in the groove 12, after being equipped with, height drafting board 13 can be to the high-low-position of the second core 18
Put and measure and position, the downside of the bottom plate 1 fixed setting limited block 14, for adjusting the position of the first core 17, simultaneously
And the support part of whole positioning harness, the overall dimensions requirement using this device for casting, in the anabolic process of casting mold
In, with this harness, the position dimension in core horizontal direction and height direction is can adjust, all directions dimension control can be existed
Within the scope of ± 1mm, ensure that the gap between multiple cores 17 of second core 18 and first is basically identical, the height of the second core 18
Lower position is consistent, so as to produce the casting of uniform wall thickness, improves the quality of casting, reduces the percent defective of casting.
The upside both ends of bottom plate 1 set shadoof 15 respectively, can facilitate and harness is moved, on the horizontal survey seat 5
The observation window 16 for observing gap between locating piece and block is provided with, facilitates accurate positioning, and to the size of the second core 18
Repaired, it is easy to use, effectively lift casting quality.
It is as follows using process：
In casting mold group core, first casting mold nowel, casting mold raising middle flask and the combination of the first core 17 are put together, then use hand adjustment
The position of whole first core 17, grasps shadoof 15, and positioning harness is put into the die cavity of casting mold, makes 4 of the bottom of bottom plate 1
Limited block 14 is put into the gap of the first core 17 and casting mold raising middle flask, while the bottom of bottom plate 1 and the upper surface of the first core connect
Touch.So, the central alignment of the first core 17 and casting mold raising middle flask, its centre deviation meet the requirement of casting.
Second core 18 is multiple, and two one group, the present embodiment uses 6, and 3 groups of composition is symmetrical, first to first group
Positioned, positioning is in two steps：The first step：Horizontal location.After one group of second core 18 is substantially put well, with hand propelled holding rod
10, when the C faces of horizontal drafting board 7 and the D faces of the second core 18 just contact, the A faces of horizontal drafting board 7 are checked by observation window 16
Gap between the B faces of block 8, ideal position state be horizontal drafting board 7 A faces and block 8 B faces contact when, level survey
The C faces of plate 7 and the D faces of the second core 18 just contact.If there is certain gap between locating piece 9 and block 8, by the second sand
Core 18 takes out, and according to the size of this gap, the E faces of the second core 18 is ground off into a part with emery wheel, is put into casting mold and surveys again
Amount, above step is repeated, when the C faces of horizontal drafting board 7 and the D faces of the second core 18 just contact, the A faces of horizontal drafting board 7
Also just contacted with the B faces of block 8, now the horizontal level of the second core 18 is just set.
With same method, another symmetrical second core 18 is positioned.
Second step：Height positions.After the horizontal location of second core 18, height drafting board 13 is put into the groove of horizontal drafting board 7
In 12, moving slide board 4, whether the lower surface of observation height drafting board 13 and the upper surface of the second core 18 are concordant, if concordantly, do not repaiied
The lower surface of whole second core 18, until the upper surface of the second core 18 is concordant with the lower surface of height drafting board 13, now core
II high and low position is just set.
Now first group of second positioning of core 18 is completed.
After first group of second core 18 is had good positioning, with hand moving slide board 4, level measurement device is driven to be moved to the successively
The position of two groups, the 3rd group cores II, horizontal and high-low-position is carried out with above-mentioned second group same of method knot, the 3rd group of core II
The positioning put.
After core fixes, shadoof 15 is grasped, positioning harness is taken out from casting mold, it is possible to is poured into a mould, used
This positioning harness, it is ensured that the gap between the second core 18 and the first core 17 is of substantially equal, and position is relatively fixed, so as to protect
Casting dimension requirement is demonstrate,proved, the dimensional accuracy and casting quality of casting is improved, reduces casting wasted product rate.
Embodiment described above is only preferred embodiment of the present utility model, and the not feasible implementation of the utility model
It is exhaustive.For persons skilled in the art, on the premise of without departing substantially from the utility model principle and spirit, it is made
Any obvious change gone out, should all be contemplated as falling with claims of the present utility model.
