Abstract
The simple locking nut has circular nut body, circular arc slot penetrating the wall thickness of the nut and with regulating screw in the middle part parallel to the axis of the nut. The utility model discloses a be suitable for among the machine parts assembling process restricted occasion in structure and space to carry out clearance adjustment and locking, have and save space, convenient operation uses reliable obvious advantage.
Description
Technical field
The utility model relates to a kind of component of machine assembly process that is used for and carries out the easy locking nut that the gap is adjusted and locked.
Background technique
Two nuts are often adopted in the fit up gap of component and fastening in the machinery industry, after first nut adjusted the gap, splice with second nut again, prevent to become flexible.But be subjected to the restriction in structure and space in many occasions, can't lock with standard nut, for example when processing and assembling is used for the special boring mill boring template frame rolling bushing of diesel-engine body spindle hole, camshaft hole processing, the axial play of rolling bearing just can't be adjusted and lock because of the influence that is subjected to the mould bases structure and the needs of bearing seal with standard nut.
The model utility content
It is a kind of easy to operate that the purpose of this utility model is to provide, and is applicable to the easy locking nut of structure and limited space system occasion.
The technical solution of the utility model is: the main body of easy locking nut is a round nut, along the circumferential direction has the curve bath that penetrates the nut wall thickness on the periphery of round nut, and the curve bath intermediate portion is provided with the adjusting screw that is parallel to the nut axis.
Further scheme is the size a=4～6mm of described curve bath from nut one end, groove width b=2～3.5mm, and groove depth h=D/2+ (2～4) mm, wherein D is the round nut external diameter; Described adjusting screw is the sunk screw of M3～M5.
When the utility model uses, be enclosed within on the workpiece, adjust axial clearance after, tighten adjusting screw, make the nut inner thread thread form produce distortion clamping work pieces outside thread at the fluting place, reach the locking purpose.Only need a nut in the use, play the locking effect, save the space by the axial adjustment screw, easy to operate, be applicable to the occasion of structure and limited space system in the machinery assembling.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
As figure, the utility model along the circumferential direction has the curve bath 3 that penetrates the nut wall thickness at the periphery of round nut 1, and the curve bath intermediate portion is provided with the adjusting screw 2 that is parallel to the nut axis.Among this embodiment, round nut is M16, and curve bath is from nut end face size a=5mm, groove width b=3mm, and groove depth h=D/2+3mm, D are the external diameter of round nut, adjusting screw 2 is selected sunk screw M4 for use.
Claims (3)
1. easy locking nut, main body is a round nut, it is characterized in that the round nut periphery along the circumferential direction has the curve bath that penetrates the nut wall thickness, the curve bath intermediate portion is provided with the adjusting screw that is parallel to the nut axis.
2. by the described easy locking nut of claim 1, it is characterized in that size (a)=4～6mm of described curve bath from nut one end, groove width (b)=2～3.5mm, groove depth (h)=(D)/2+ (2～4) mm, wherein (D) is the round nut external diameter.
3. by the described easy locking nut of claim 1, it is characterized in that described adjusting screw is the sunk screw of M3～M5.
