Abstract
The utility model relates to a punching rod locking component for a punching die of a drill rod joint, which comprises a punching rod and a die holder, wherein the punching rod is connected to the die holder, the punching rod locking component also comprises a locking nut, a mount hole is formed on the die holder, a ring-shaped stopper is arranged on the circumference of the punching rod, the end part of the punching rod passes through the mount hole of the die holder, and the locking nut is in threaded connection with the end part of the punching rod and leans against the upper end face of the die holder. The punching rod locking component is installed reliably and saves the manufacturing cost.
Description
Technical field
The utility model relates to a kind of tool joint perforating die jumper bar latch assembly.
Background technology
During present installing drill knock-off joint perforating die jumper bar, jumper bar just directly is threaded with die holder, because jumper bar needs often to change, and when using, bear press down and on draw double reaction plus, easily cause thread looseness, damage, cause jumper bar and die holder damage and scrap, increased manufacturing cost.
Summary of the invention
The purpose of this utility model is to provide a kind of installation reliable, saves the tool joint perforating die jumper bar latch assembly of manufacturing cost.
In order to achieve the above object, the technical solution of the utility model is: a kind of tool joint perforating die jumper bar latch assembly, comprise jumper bar and die holder, jumper bar and die holder load also comprise locking nut, and die holder is provided with installing hole, the periphery of jumper bar is provided with annular stop, the installing hole of die holder is passed in the end of jumper bar, and locking nut is connected with the jumper bar end thread, and offsets with the die holder upper surface.
Described installing hole is that stepped hole and place, the lower surface that is positioned at die holder are the spacing hole of macropore section, and the annular stop of jumper bar is positioned at spacing hole.
The end face of described locking nut is provided with locking slot.
After adopting said structure, owing to also comprising locking nut, die holder is provided with installing hole, and the periphery of jumper bar is provided with annular stop, and the installing hole of die holder is passed in the end of jumper bar, and locking nut is connected with the jumper bar end thread, and offsets with the die holder upper surface.Therefore after locking nut passes the installing hole of die holder at jumper bar, can well lock jumper bar, install reliable, and if the locking nut wearing and tearing, as long as change locking nut, do not need to change die holder yet, saved manufacturing cost.
Description of drawings
Fig. 1 is half sectional view of the present utility model;
Fig. 2 is the top view of the locking nut of Fig. 1.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.
Shown in Fig. 1,2, a kind of tool joint perforating die jumper bar latch assembly, comprise jumper bar 1 and die holder 2, jumper bar 1 and die holder 2 loads also comprise locking nut 3, and die holder 2 is provided with installing hole 2-1, the periphery of jumper bar 1 is provided with annular stop 1-1, the installing hole 2-1 of die holder 2 is passed in the end of jumper bar 1, and locking nut 3 is connected with jumper bar 1 end thread, and offsets with die holder 2 upper surfaces.
Shown in Figure 1, in order to prevent that jumper bar 1 from rotating when screwing, and better spacing under joint space-efficient prerequisite, described installing hole 2-1 is that stepped hole and place, the lower surface that is positioned at die holder 2 are the spacing hole 2-2 of macropore section, the annular stop 1-1 of jumper bar 1 is positioned at spacing hole 2-2.
Shown in Figure 1, screw locking nut 3 in order better to use the instruments such as spanner, the end face of described locking nut 3 is provided with two locking slot 3-1.
Shown in Fig. 1,2, when the utility model uses, first the end of tool joint perforating die jumper bar 1 is passed the installing hole 2-1 of die holder 2, made the annular stop 1-1 of jumper bar 1 be positioned at spacing hole 2-2, and locking nut 3 is connected with jumper bar 1 end thread, thereby locking jumper bar 1, the utility model can well be locked jumper bar 1, installs reliable, if locking nut 3 wearing and tearing, as long as change locking nut 3, do not need to change die holder 2 yet, saved manufacturing cost.
