Description
Technical field
The invention belongs to engineering machinery field, and in particular to a kind of drill jumbo lengthens push rod.
Background technology
Drill jumbo lengthens push rod main rod body with stress axis since section differs larger at this stage, although being heat treatment of the same race
Technique is processed, but after final molding, the material mechanical mechanical property of stress axis will be less than the material mechanical mechanical property of main rod body,
This have impact on the service life harmony for lengthening push rod entirety.In boring procedure, stress bearing carry more energetically, periodic impact,
Under twisting action, stress axis is easy in the fracture of root being connected with main rod body.After stress axle fracture, lengthen push rod and integrally can
Scrap, cause great waste.Based on the above problem, it is necessary to it is whole to lengthen push rod to invent a kind of drill jumbo lengthening push rod
The harmony of body life time, reduces use cost.
The content of the invention
To solve the above problems, the present invention provides a kind of drill jumbo to lengthen push rod.
The present invention is achieved through the following technical solutions：A kind of drill jumbo lengthens push rod, including main rod body, secondary bar
Body, stress axis and lock nut, the main rod body include main rod body matrix and male end；The secondary bar body includes secondary bar body
Matrix and female end, stress shaft mounting hole are provided with the secondary bar body matrix, being equipped with the stress shaft mounting hole to reduce
Concentrated stress when stress axis works is equipped with assembling so as to improve the cambered surface of its service life, on the outside of the secondary bar body matrix and lengthens
Anti-rotation groove during push rod for reinforcing；The stress axis includes external screw thread and stress axis matrix, the male threaded end are equipped with
Chamfering a, the stress axis matrix are equipped with chamfering b away from externally threaded end, are provided with pin hole below the chamfering b, main rod body with
Secondary bar body, which is connected through a screw thread, to be relatively fixed；Stress axis is inserted into the hole of secondary bar body, the two interference fit；Lock nut and stress axis
It is connected through a screw thread, is relatively fixed.The number of equally distributed anti-rotation groove is 4 on the outside of the female end.
Beneficial effects of the present invention：The present invention can effectively lengthen the harmony of push rod bulk life time, in use
If stress axle fracture, stress axis can be pulled down, be changed to new stress axis, then entirely lengthening push rod still can normally make
With reducing use cost.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention；
Fig. 2 is the internal structure schematic diagram of Fig. 1；
Fig. 3 is main rod body structure diagram；
It is secondary bar body structure diagram with 4；
Fig. 5 is stress axle construction schematic diagram；
Fig. 6 is the internal structure schematic diagram of Fig. 4.
In figure：1st, main rod body, 2, secondary bar body, 3, stress axis, 4, lock nut, 1-1, main rod body matrix, 1-2, external screw thread
End, 2-1, secondary bar body matrix, 2-2, female end, 2-3, stress shaft mounting hole, 2-4, cambered surface, 2-5, anti-rotation groove, 3-1, fall
Angle a, 3-2, chamfering b, 3-3, pin hole, 3-4, external screw thread, 3-5, stress axis matrix.
Embodiment：A kind of drill jumbo lengthens push rod, including main rod body 1, secondary bar body 2, stress axis 3 and locking
Nut 4, main rod body 1 include main rod body matrix 1-1 and male end 1-2；Secondary bar body includes secondary bar body matrix 2-1 and female end
Stress shaft mounting hole 2-3 is provided with 2-2, secondary bar body matrix 2-1, stress axis 3 can be reduced by, which being equipped with stress shaft mounting hole 2-3, works
When concentrated stress be equipped with when assembling lengthens push rod and use so as to improve the cambered surface 2-4 of its service life, on the outside of secondary bar body matrix 2-1
In the anti-rotation groove 2-5 of reinforcing；Stress axis 3 includes external screw thread 3-4 and stress axis matrix 3-5, external screw thread 3-4 ends are equipped with chamfering
The end of a3-1, stress axis matrix 3-5 away from external screw thread 3-4 is equipped with chamfering b3-2, and pin hole 3-3 is provided with below chamfering b3-2, main
The body of rod 1 is connected through a screw thread with secondary bar body 2 and is relatively fixed；Stress axis 3 is inserted into the hole of secondary bar body 2, the two interference fit；Locking spiral shell
Mother 4 is connected through a screw thread with stress axis 3, is relatively fixed.The number of equally distributed anti-rotation groove 2-5 on the outside of female end 2-2
It is 4.
When assembling lengthens push rod, it is aided with instrument and blocks anti-rotation groove 2-5, secondary bar body 2 is revolved and to main rod body 1 up to cannot
Untill rotation, by the chamfering a3-1 of stress axis 3, stress shaft mounting hole 2-3 is inserted into, is aided with instrument and taps chamfering b3-2, until striking
Hit untill stress axis 3 cannot be gone successively to, at this moment the end face of the chamfering a3-1 of stress axis 3 and the end face of male end 1-2 are pasted
Close.Main rod body 1 is separated with secondary bar body 2, by lock nut 4 and external screw thread 3-4 revolve and to cannot continue rotation and untill, Ran Houchong
Newly by main rod body 1 and secondary bar body 2 revolve and to cannot revolve and untill, entirely lengthen push rod completion at this time.
After stress axis 3 is broken, main rod body 1 is separated with secondary bar body 2, lock nut 4 is separated with external screw thread 3-4, it is auxiliary
The end face of chamfering a3-1 is tapped with instrument, untill stress axis 3 is separated with secondary bar body 2, replaces stress axis 3, by lengthening push rod
Installation step is recovered to lengthen push rod.
The present invention can effectively lengthen the harmony of push rod bulk life time, in use if stress axle fracture,
Stress axis can be pulled down, be changed to new stress axis, then entirely lengthen push rod still can with normal use, reduce use into
This.
