Background technology
Drilling bit is important drilling tool, and nozzle wherein is fixed on the drilling bit with collar, after using the regular hour, need pull down nozzle place under repair or replacing.But the extracting tool that the dismounting nozzle is never special-purpose must use instruments such as Circlip tongs, iron rod, iron hammer when dismounting, not only waste time and energy, and also can cause damage to equipment.
Summary of the invention
Technical problem to be solved provide a kind of easy to use, can not damage equipment, dismantle drilling bit nozzle extracting tool fast.
The technical scheme that solves its technical problem is as follows: drilling bit nozzle extracting tool comprises overcoat, pull bar, handle, jump ring folder and expansion-head; The overcoat central bore is divided into three sections, the epimere diameter is less internal thread, the stage casing diameter is greater than endoporus epimere diameter, the hypomere diameter is greater than endoporus stage casing diameter, up-small and down-big round taper hole is arranged between endoporus stage casing and hypomere, the last diameter of round taper hole equals endoporus stage casing diameter, and the following diameter of round taper hole equals endoporus hypomere diameter; Pull bar is divided into three sections, the pull bar epimere is the thread segment that diameter equals overcoat endoporus epimere diameter, the pull bar stage casing is the second order boss, last rank boss diameter is less than overcoat endoporus stage casing diameter, following rank boss diameter is less than overcoat endoporus hypomere diameter, the pull bar lower end is up-small and down-big cone, and the expansion-head that rubber-plastics material is made is enclosed within the outside, lower end of pull bar, and the external diameter of expansion-head is slightly less than drilling bit nozzle endoporus internal diameter; The endoporus of expansion-head is up-small and down-big round taper hole, and the upper end diameter in inner conical hole equals pull bar lower end cone upper end diameter, and lower end diameter equals the lower end diameter of pull bar lower end cone; Pull bar is contained in the internal thread hole of overcoat endoporus epimere with the thread segment of its epimere; End, pull bar upper end is a square spigot, and handle connects as one with pull bar thereon with the square opening cover of its left end; On the outside of the columnar jump ring chuck of slot at pull bar stage casing second order boss arranged, between the outer surface and overcoat endoporus hypomere of second order boss, the appearance of jump ring folder is divided into two sections, the external diameter of hypomere is slightly less than the diameter of overcoat endoporus hypomere, epimere is up-small and down-big cone, the cone upper end diameter is slightly less than overcoat endoporus stage casing diameter, the cone lower end diameter equals jump ring folder appearance hypomere diameter, the endoporus of jump ring folder is divided into two sections, the internal diameter of endoporus epimere is slightly larger than the external diameter on rank on the second order boss of pull bar stage casing, and the internal diameter of endoporus hypomere is slightly larger than the external diameter on rank under the boss of pull bar stage casing; There are two bayonet locks the lower end of the seam of jump ring folder, and the width between the bayonet lock equals to block the width between two stomidiums of collar of nozzle.
During operation, with the expansion-head that is contained in the pull bar lower end nozzle endoporus of packing into, the bayonet lock on the jump ring folder stretches in two stomidiums of collar of fixed nozzle.Rotary handle moves up pull bar, under the drive of the second order boss in pull bar stage casing, make on the jump ring folder and move, the relative slip of taper seat do in the taper seat of jump ring folder epimere and the overcoat, between the hypomere, jump ring is clamped to contract, slot width and bayonet lock spacing reduce, and the spacing of collar two stomidiums of fixed nozzle is reduced.Simultaneously, when moving on the pull bar, the coned face of pull bar lower end promotes expansion-head and outwards opens, and nozzle can be taken out from the installing hole drilling bit.
Beneficial effect: the utility model is applied to the maintenance of drilling bit nozzle, and beneficial effect is that the dismounting nozzle is quick and convenient, can not damage equipment.The specific purpose tool that can be used as the dismounting nozzle is promoted the use of.
