Description
Technical field
The utility model is related to diesel engine manufacturing field, specifically a kind of Novel diesel engine cross bolts twisting angle instruction
Device.
Background technology
Middle high speed diesel engine main beating cap is fixed on the machine body by main-bearing stud and cross bolts, cross bolts tightening force
Square has a stringent technological requirement, and screw-down torque is excessive or too small can be had an impact to base bearing aperture.
Angle is tightened according to existing installation method in body and upper picture mark line, sleeve is inserted in cross bolts, according to behaviour
Make experience and substantially tighten bolt to line position is marked, splits out sleeve and check bolt mark line and body mark line difference angle, then
It is secondary to tighten bolt, until bolt mark line is overlapped with body mark line.Rundown process is repeated multiple times, and it is super that bolt mark line easily occurs
The problem of crossing body mark line.
Utility model content
The purpose of this utility model is to provide a kind of Novel diesel engine cross bolts twisting angle instruction devices, to solve
The problems mentioned above in the background art.
To achieve the above object, the utility model provides the following technical solutions：
A kind of Novel diesel engine cross bolts twisting angle instruction device, including fixed plate and fixed frame；The fixed frame
Top has been bolted to connection fixed plate, and fixed frame lower end is equipped with through-hole, sleeve is arranged in the through-hole of fixed frame lower end；
The sleeve is rotatablely connected by guide sleeve and through-hole wall, and sleeve outer sheath is equipped with indicating ring；The indicating ring outer wall and solid
Determine frame outer wall and is marked with graduation mark.
As further program of the utility model：It is equipped with bolt overlap aperture on the right side of the sleeve, is equipped with and pulls on the left of sleeve
Gloves apertured.
As further program of the utility model：The indicating ring is fixedly connected by screw with sleeve.
Compared with prior art, the utility model has the beneficial effects that：The utility model is easy to use, and rundown process unloads letter
It is single quick, it is easy to operate；Working hour is saved, need not be confirmed in rundown process using this tightening tool and tighten angle, reduced
Angle in a large amount of rundown process confirms work；Quality controllability is improved, cross bolts screw-down torque is avoided and is wanted beyond technology
The risk asked；The utility model is simple in structure, and component is few, easy to process.

Fig. 2 is the structural schematic diagram of fixed frame in Novel diesel engine cross bolts twisting angle instruction device；
Fig. 3 is the sectional view of Novel diesel engine cross bolts twisting angle instruction device middle sleeve.
In figure：1- fixed plates；2- fixed frames；3- indicating rings；4- guide sleeves；5- sleeves；6- bolts；7- screws.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Please refer to Fig.1~3, in the utility model embodiment, a kind of Novel diesel engine cross bolts twisting angle instruction dress
It sets, including fixed plate 1 and fixed frame 2；2 top of the fixed frame is fixedly connected with fixed plate 1,2 lower end of fixed frame by bolt 6
Equipped with through-hole 21, sleeve 5 is arranged in 2 lower end through-hole 21 of fixed frame；5 right side of the sleeve is equipped with bolt overlap aperture 51, bolt
Cross bolts 53 are socketed in overlap aperture 51,5 left side of sleeve is equipped with spanner overlap aperture 52, and spanner overlap aperture 52 is used for being socketed outside
Spanner；The sleeve 5 is rotatablely connected by guide sleeve 4 and 21 inner wall of through-hole, and 5 outer sheath of sleeve is equipped with indicating ring 3, indicating ring
3 are fixedly connected by screw 7 with sleeve 5, and indicating ring 3 rotates on sleeve 5, is fixed by screw 7；The indicating ring 3
Outer wall and 2 outer wall of fixed frame are marked with graduation mark.
The operation principle of the utility model is：According to the requirement of bolt screwed indicating ring is rotated by screwing screw 7
3, so that swivel becket 3 is turned to certain angle, then screw 7 is screwed so that indicating ring 3 is relatively fixed with sleeve 5, by sleeve 5
Bolt hole be inserted in the heads of cross bolts 53, by the insertion spanner overlap aperture 52 of external spanner insertion sleeve 5, rotation is outer
Portion's spanner, external key drive cross bolts 53 to rotate by sleeve 5, while indicating ring 3 being driven to rotate, when on indicating ring 3
Graticule on graticule and fixed frame 2 tightens requirement at that time, that is, meet spiral；Cross bolts do not have in rundown process
Duplicate acknowledgment bolt tightens whether angle meets technology requirement, avoids bolt and tightens the wind that angle exceeds technology claimed range
Danger.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this practicality is new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this practicality is new
