Abstract
The utility model belongs to the auxiliary mould in internal combustion engine mounting technology field, specifically related to a kind of bolt/nut degree of tightening limits sleeve, including cylindrical body, one end of cylindrical body has the connecting portion of the interior Hexagonal jacket that can connect pneumatic rifle, the cylindrical body other end has circular hole of the aperture more than or equal to the circumscribed circle diameter of the hexagonal hole of the interior Hexagonal jacket, and the circular hole is connected with the hexagonal hole of interior Hexagonal jacket, can enter in circular hole during making bolt/nut backspin, and depart from interior Hexagonal jacket, and then stop backspin.The utility model arranges spacing collar between the interior Hexagonal jacket and fitting surface of pneumatic rifle, when bolt or nut can be departed from interior Hexagonal jacket when entering in spacing collar, so as to stop backspin, as long as the height for adjusting spacing collar just can be through the screw-in depth of accurately control bolt or nut, so as to precise control bolt or the screw-down torque of nut.
Description
Technical field
The utility model belongs to the auxiliary mould in internal combustion engine mounting technology field, and in particular to a kind of bolt/nut is tightened
Degree limits sleeve.
Background technology
The parts such as the oil sump of internal combustion engine are mostly attached with body using bolt, when bolt is assembled, it is necessary first to
Bolt is mounted on screwed hole by hand in advance, then using pneumatic rifle fastening.Pneumatic rifle front end be provided with bolt match in six
Angle sleeve, due to without position limiting structure between interior Hexagonal jacket and mounting surface, therefore in fastening bolt, even if bolt with
Fitting surface is fitted tightly, but as long as bolt is located in interior Hexagonal jacket, air operated machine still can produce certain torque to bolt, and this is just
Cause the torque of bolt be controlled, torque is bigger than normal or less than normal all by the performance of impact engine.
Utility model content
The purpose of this utility model is to provide a kind of bolt/nut degree of tightening that can control bolt degree of tightening to limit set
Cylinder.
For achieving the above object, the utility model provides technical scheme below：A kind of bolt/nut degree of tightening limits set
Cylinder, including cylindrical body, one end of cylindrical body has the connecting portion of the interior Hexagonal jacket that can connect pneumatic rifle, cylindrical body
The other end have aperture more than or equal to the interior Hexagonal jacket hexagonal hole circumscribed circle diameter circular hole, and the circular hole with
The hexagonal hole connection of interior Hexagonal jacket, can enter in circular hole during making bolt/nut backspin, and de- with interior Hexagonal jacket
From, and then stop backspin.
The connecting portion is one section and can be enclosed within interior Hexagonal jacket outside the outer ring surface composition interference with interior Hexagonal jacket
The cannula portion of cooperation.
Coaxially fixed using welding manner between the cylindrical body and the interior Hexagonal jacket.
The barrel of the cylindrical body is stepped, and the barrel dliameter of wherein cannula portion answers the barrel dliameter of section more than circular hole；And circular hole
The external diameter of the cylindrical body of section is roughly equal with the external diameter of the interior Hexagonal jacket.
Round-corner transition is adopted between the outer ring surface in described sleeve pipe portion and the outer ring surface of circular hole portion.
Of the present utility model have technical effect that：The utility model is set between the interior Hexagonal jacket and fitting surface of pneumatic rifle
Spacing collar is put, when bolt or nut can be departed from interior Hexagonal jacket when entering in spacing collar, so as to stop backspin, as long as
Adjust the height of spacing collar just can through the screw-in depth of accurately control bolt or nut, so as to precise control bolt or
The screw-down torque of nut.

Specific embodiment
The utility model is described in detail below in conjunction with accompanying drawing.
As shown in Fig. 1 to 5, a kind of bolt/nut degree of tightening limits sleeve, including cylindrical body 10, cylindrical body 10
One end has the connecting portion of the interior Hexagonal jacket 20 that can connect pneumatic rifle, and 10 other end of cylindrical body has aperture and is more than or waits
In the circular hole 12 of the circumscribed circle diameter of the hexagonal hole 21 of the interior Hexagonal jacket 20, and the circular hole 12 and interior Hexagonal jacket 20
Hexagonal hole 21 is connected, and can be entered in circular hole 12 during making bolt/nut backspin, and is departed from interior Hexagonal jacket 20, is entered
And stop backspin.The utility model arranges spacing collar between the interior Hexagonal jacket 220 and fitting surface of pneumatic rifle, when bolt or
Nut can be departed from interior Hexagonal jacket 20 when entering in spacing collar, so as to stop backspin, as long as adjusting spacing collar
Height just can be through the screw-in depth of accurately control bolt or nut, so as to precise control bolt or the screw-down torque of nut.
Preferably, the connecting portion is one section and can be enclosed within the outside and outer shroud with interior Hexagonal jacket 20 of interior Hexagonal jacket 20
Face constitutes the cannula portion of interference fit.
In addition, can also be same using welding manner between cylindrical body of the present utility model 10 and the interior Hexagonal jacket 20
Axle is fixed.
Preferably, as shown in figure 3, the barrel of the cylindrical body 10 is stepped, wherein the barrel dliameter of cannula portion is more than circle
The barrel dliameter of section is answered in hole 12；And as shown in figure 5, the external diameter of the external diameter of the cylindrical body 10 of 12 sections of circular hole and the interior Hexagonal jacket 20
Roughly equal.Generally, the bolts assemblies space that reserves on internal combustion engine is all the chi according to Hexagonal jacket in air operated machine 20
Very little design, therefore the external diameter of spacing collar is arranged to suitable with the external diameter of interior Hexagonal jacket 20 by the utility model, it is ensured that its
In practical process, interference will not be produced with other parts.
Preferably, as shown in figure 3, adopting fillet mistake between the outer ring surface of the outer ring surface in described sleeve pipe portion and 12 sections of circular hole
Cross, it is to avoid stress concentration phenomenon, improve sleeve strength.
Preferred embodiment of the present utility model is the foregoing is only, not in order to limit the utility model, all at this
Any modification, equivalent and improvement that is made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
