Abstract
The utility model discloses a kind of frock changed for development machine body otic placode, it is included in main shaft, the boss step at main shaft two ends, the alignment pin of boss step outer end and the threaded post of alignment pin outer end at the middle part on a central axis；The distance of the wherein outer edge of the boss step at main shaft two ends to outer edge is the span required by the body otic placode of standard；The external diameter of alignment pin is slightly less than the internal diameter required by otic placode pin shaft hole, and length dimension is slightly less than the thickness of otic placode；The threaded post at two ends is used to be connected with the nut of compression.The utility model can be solved when auxiliary repairs otic placode, can not only the original body of retaining device be continuing with and also can guarantee that the otic placode of reparation with one heart, unanimously reach standard size, and construct the technical problem such as simple and easy to use.
Description
Technical field
The utility model is related to a kind of maintenance tool of development machine.
Background technology
During the development machine overhaul of nearly 2 years, frequent appearance excess load when project management department constructs drilling depth due to development machine
Work, and cause the situation of body otic placode gross distortion.There is each 4 pairs up and down of otic placode on one development machine body, to connect 2
Cut hoist cylinder and 2 shovel board hoist cylinders.Otic placode is that oil cylinder moves back and forth most laboriously position, therefore in development machine overhaul
During otic placode almost per playscript with stage directions body have different degrees of deformation.The otic placode and body of body are an entirety, are whole
Maximum most heavy position in development machine, price is also very high, and each price is more than 60,000 yuan.Merely because otic placode deformation is just changed
Body cost is too high.
Once the damage of development machine otic placode will seriously change whole body, price is very high, and supplier is slow with the goods cycle,
Often a body is accomplished by waiting 2 weeks or so.Simultaneously because bulk volume is big, weight weight.Freight charges cost is also very high.Adopt later
With the otic placode and the method for the new otic placode of welding for slicing off damage, because sheet material is too thick, it is difficult to span and welding deformation amount in control.It is past
Occur deforming after the completion of toward welding spends substantial amounts of manpower and materials to be adjusted reparation again.Cause substantial amounts of waste.
The content of the invention
The purpose of this utility model is to provide a kind of frock changed for development machine body otic placode, to solve to repair in auxiliary
During multiple otic placode, can not only the original body of retaining device be continuing with and can guarantee that the otic placode of reparation reaches mark with one heart, unanimously
Object staff cun, and construct the technical problem such as simple and easy to use.
In order to realize foregoing invention purpose, the technical scheme that the utility model is used is as follows：
A kind of frock changed for development machine body otic placode, is included in main shaft, the master at middle part on a central axis
Boss step, the alignment pin of boss step outer end and the threaded post of alignment pin outer end at axle two ends；Wherein main shaft two ends
The distance of the outer edge of boss step to outer edge is the span required by the body otic placode of standard；The external diameter of alignment pin is smaller
In the internal diameter required by otic placode pin shaft hole, length dimension is slightly less than the thickness of otic placode；The threaded post at two ends is used for the spiral shell with compression
Mother's connection.
Advantage of the present utility model and good effect：
After the utility model progress frock, every development machine replacing otic placode only needs to two people and spends a couple of days
Time, it can just complete.Replacement cost is even more to buy new body than before to have saved six or seven ten thousand.
1st, the technology aided in using the utility model frock has carried out Replacement and Repair to the body otic placode of gross distortion.Avoid
Because the situation that otic placode is deformed and causes whole body to be changed
2nd, using this frock, the otic placode newly changed can be simply made to meet required span, aperture and concentricity.
And strictly control welding deformation.Overhaul cost is reduced, the overhaul life is shortened.
Brief description of the drawings
Fig. 1 is structural representation front view of the present utility model.
Fig. 2 is Fig. 1 right view.
Embodiment
Concrete structure of the present utility model is referring to shown in Fig. 1,2.A kind of frock changed for development machine body otic placode, bag
Include the main shaft 1 at middle part on a central axis, the boss step 2 at main shaft two ends, 3, the alignment pin of boss step outer end
4th, 5 and alignment pin outer end threaded post 6,7；Wherein distance of the outer edge of the boss step 2,3 at the two ends of main shaft 1 to outer edge
For the span required by the body otic placode of standard；The external diameter of alignment pin 4,5 is slightly less than the internal diameter required by otic placode pin shaft hole, long
Degree is dimensioned slightly smaller than the thickness of otic placode；The threaded post 6,7 at two ends is used to be connected with the nut of compression.
Specifically used mode：
1：The otic placode of the damage deformation on script body is sliced off from root first and two-sided at slot groove is beaten.Slot one
Surely side gusset rear is reached close proximity to root, to ensure the upper later intensity of later stage welding.The position that each pair otic placode is sliced off
Put and be consistent as far as possible.
2：Otic placode appearance profile to slice off selects same material, the steel plate cutting of same thickness, then uses boring as model
Bed bores the internal diameter of the pin shaft hole required by standard otic placode.
3：Frock making：The similar bearing pin of car as shown in Figure 1, 2 is come with the pin shaft hole internal diameter and span of standard otic placode requirement
Positioner.Span required by the outside of two steps of frock to the body otic placode that outer back gauge X is standard.Y is this in figure
The external diameter of alignment pin, is slightly less than the internal diameter required by otic placode pin shaft hole.The Z thickness for being dimensioned slightly smaller than otic placode.Two ends car goes out
M24 screw thread.
4：When changing otic placode, two pieces of the good hole of boring before new otic placodes are inserted to the both sides of frock from two ends respectively.Adjust
Angle.Two pressing plates are inserted from both sides and compressed with M24 nuts again.Then otic placode is butted up against and cutting for old otic placode is sliced off on body
At seam.Fixed with electric welding first point.
5：Two pairs of otic placodes in both sides are fixed, when proceeding by welding, home record in the middle of the otic placode fixed in both sides
Place adds a pipe even at the cost of one's life to prevent welding deformation.
