Technical Field
The utility model relates to a logging instrument deep hole processing technology field in the oil well especially relates to a deep hole machining cutter.
Background
At present, a deep hole boring machine is generally adopted to process deep holes of a petroleum underground logging instrument, the deep hole drilling and boring machine is mainly used for deep hole processing such as deep hole drilling, reaming and boring, and the radial-to-length ratio of the processing depth can be 40 times or even higher. In the machining process, the damage condition of the cutter is difficult to master, an operator usually judges the wear condition of the wear-resistant strips according to the working experience of the operator and replaces the wear-resistant strips, and the method is not only wasteful, but also has high technical requirements on the operator.
Disclosure of Invention
For overcoming the not enough of prior art, the utility model provides a deep hole machining cutter can finely tune automatically, has increased the life of cutter, has improved machining efficiency.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a deep hole machining tool comprises a tool body, a wear-resistant strip, a conversion joint and a fine adjustment nut; the wear-resistant strip, the fine adjustment nut and the adapter are sequentially arranged on the cutter body; the cutter main body comprises a cone and a stud, a plurality of grooves are formed in the side face of the cone, and the wear-resistant strips are placed in the grooves and fixed through the bolts; the wear-resistant strips are strip-shaped, the side surfaces are 4 surfaces, one surface of the wear-resistant strips is provided with an inclined surface consistent with the inclination of the cutter main body cone, and the opposite surface of the inclined surface is provided with an arc surface; the adapter is provided with an internal thread matched with the stud, and the adapter is connected with the cutter body through the thread.
The cutter main body is made of 42CrMo material.
The wear-resistant strips are made of polyamide plate materials.
Compared with the prior art, the beneficial effects of the utility model are that:
(1) the wear-resistant strip adopts the conical surface design with a thin upper part and a thick lower part, and is matched with the slope design of the reverse processing direction of the cutter main body, so that the reaction force of the matched processing and the torsion of a workpiece in the processing process increase the effect of automatic fine adjustment on the wear-resistant strip, and the adjustment effect of the wear-resistant strip in the diameter direction of 2 mm can be realized by matching with a fine adjustment nut. The abrasion condition of the abrasion-resistant strip is convenient to judge, the service life of the cutter is prolonged, the machining efficiency is improved, and the production cost is reduced.
(2) The wear-resistant strips are made of polyamide plates, and have the advantages of high mechanical strength, high hardness, super wear resistance, high toughness, low deformation rate, high stability, good aging resistance and good mechanical shock absorption capacity.
(3) The cutter body is made of 42CrMo material; the high-strength high-toughness steel has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after quenching and tempering treatment, and good low-temperature impact toughness.

Detailed Description
The following describes the present invention in further detail with reference to the accompanying drawings.
As shown in fig. 1-5, a deep hole machining tool comprises a tool body 1, a wear strip 3, a crossover sub 2 and a fine adjustment nut 4.
The cutter body 1 comprises a cone 5 and a stud 6, and 4 grooves 7 are symmetrically arranged on the side surface of the cone 5.
The cutter main body 1 is made of 42CrMo material, has high strength and toughness, good hardenability, no obvious tempering brittleness, higher fatigue limit and multiple impact resistance after quenching and tempering, and good low-temperature impact toughness.
The wear-resistant strips 3 are strip-shaped, the side surfaces are 4 surfaces, one surface is provided with an inclined surface 8 with the same inclination as that of the cone 5 of the cutter main body 1, one end is thin, the other end is thick, and the opposite surface of the inclined surface 8 is provided with an arc surface 9.
The wear-resistant strips 3 are made of polyamide plates, and have the advantages of high mechanical strength and hardness, super wear resistance, high toughness, low deformation rate, high stability, good aging resistance and good mechanical shock absorption capacity.
The wear-resistant strips 3 are placed in the grooves 7 and fixed through bolts.
The adapter 2 is provided with an internal thread matched with the stud 6, and the adapter 2 is connected with the cutter body 1 through the thread.
The fine adjustment nuts 4 are standard parts, and 2 fine adjustment nuts 4 are arranged on the cone 5 and located between the wear-resistant strips 3 and the adapter 2.
Wear-resisting strip 3 adopts the conical surface design of upper thin lower thick, cooperates the domatic design of the anti-process direction of tool body 1, makes the reaction force of cooperation processing and the torsion of work piece make wear-resisting strip 3 increase the effect of an automatic fine setting in the course of working, cooperates fine setting nut 4 again and can realize the adjustment effect in wear-resisting strip diameter direction 2 millimeters.
The utility model discloses be convenient for judge the wearing and tearing condition of wear strip 3, increased the life of cutter, improved machining efficiency, reduced manufacturing cost.
The above embodiments are implemented on the premise of the technical solution of the present invention, and detailed implementation and specific operation processes are given, but the protection scope of the present invention is not limited to the above embodiments. The methods used in the above examples are conventional methods unless otherwise specified.
