Abstract
The utility model provides a tool special for machining an external thread by a lathe. The tool comprises a positioning part and a connection part, wherein the positioning part consists of a column body part and a cone body part; a screw hole is formed on the side wall of the column body part; the connection part consists of a tail and a head; the tail is a column body; a hollow structure is formed in the tail; a through hole is formed on the side wall of the tail; and a clamping slot is formed in the end face of the head. The tool has the beneficial effects of simple structure, convenience in structure and low machining cost; and the external thread machining efficiency can be greatly improved.
Description
Technical field
The utility model belongs to the machined field, especially relates to a kind of machined into external screw thread specific purpose tool.
Background technology
In the machined into external screw thread process, often screw thread can not back chipping, unavoidably reaches the back chipping requirement with the screw die silk rolling, in reality processing, has that boosting-rod rotates back and forth, silk rolling, wastes time and energy with die handle silk rolling die handle both sides.Sometimes boosting-rod is long, can not turn round, and can only dismantle boosting-rod, perhaps shortens boosting-rod, the ability silk rolling, and boosting-rod is too short does not sometimes have so big strength not cross silk again.Cause the screw thread back chipping sometimes with the die handle silk rolling, can't stand so big strength, cause the fracture of shearing jackscrew or die handle to cause casualty accident sometimes if the too big die handle of pitch holds again.Promptly dangerous in such cases, can waste time and energy again, operating efficiency can not improve.
Summary of the invention
The purpose of the utility model provides a kind of machined into external screw thread specific purpose tool, and is simple in structure, simple to operate.
The technical scheme of the utility model is: a kind of machined into external screw thread specific purpose tool; Comprise positioning element and attaching parts; Said positioning element is made up of trunk portion and centrum portion, and the end face of trunk portion is fixedly connected with the end face of centrum portion, and the sidewall of trunk portion is provided with screw; Described attaching parts are made up of afterbody and head, and afterbody is fixedly connected with head, and afterbody is a cylinder; In hollow-core construction is arranged, the shape of this hollow-core construction adapts with the size and the trunk portion of positioning element, and the trunk portion of positioning element can be inserted in the afterbody of attaching parts; The sidewall of afterbody is provided with through hole; This through hole makes the inside and outside connection of said hollow-core construction, and said head is a column structure, is provided with draw-in groove in the end face of this column structure.
Further, the through hole on the said attaching parts afterbody sidewall is axial strip.
Further, the connecting portion of the afterbody of said attaching parts and head is provided with chamfering.
Further, the tip of said positioning element centrum portion is provided with the location division of cylinder body shape.
Advantage and the good effect that the utlity model has are: simple in structure, easy to maintenance, processing cost is low, can significantly improve threading efficient.

The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, special case is lifted following instance and is described with reference to the accompanying drawings as follows:
Shown in Fig. 1-2, the utility model is a kind of machined into external screw thread specific purpose tool, comprises positioning element 1 and attaching parts 2.Said positioning element 1 is made up of with centrum portion 4 trunk portion 3, and the end face of trunk portion 3 is fixedly connected with the end face of centrum portion 4, and the sidewall of trunk portion 3 is provided with screw 5, and the tip of centrum portion 4 is provided with the location division 11 of cylinder body shape; Described attaching parts 2 are made up of afterbody 6 and head 7, and afterbody 6 is fixedly connected with head 7, and the connecting portion of afterbody 6 and head 7 is provided with chamfering 10; Afterbody 6 is a cylinder, in hollow-core construction is arranged, the shape of this hollow-core construction adapts with the size and the trunk portion 3 of positioning element 1; The trunk portion 3 of positioning element 1 can be inserted in the afterbody 6 of attaching parts 2; The sidewall of afterbody 6 is provided with through hole 8, these through hole 8 preferred axes to strip, this through hole 8 makes that said hollow-core construction is inside and outside to be communicated with; Said head 7 is a column structure, is provided with draw-in groove 9 in the end face of this column structure.
The course of work of this instance: during use; Positioning element 1 usefulness tailstock is fixed; Location division 11 is stuck in and plays fixation on the tailstock, and trunk portion 3 is inserted in the afterbody 6 of attaching parts 2, and the through hole 8 that jackscrew passes attaching parts 2 is connected with the screw 5 of trunk portion 3; The position of stationary positioned parts 1, the through hole 8 of strip is convenient to regulate position component.Screw die is nested in the draw-in groove 9 of attaching parts 2 heads 7, draw-in groove 9 shapes can be square like screw die according to the screw die Adjusting Shape, and then draw-in groove 9 is square, and draw-in groove 9 is a bit larger tham screw die.The lathe gear is placed on extreme lower position, rotates the tailstock handle, make screw and screw die tangent; Recognize button; The operator added that silk oil get final product for the screw die screw like this, during the fast back chipping of screw die and working face, the quick anti-car of operator, under the left-hand thread effect, changed the instrument promotion sliding sleeve face of deactivating.Both time saving and energy saving, again safely and fast, ensured personal security.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
