Abstract
The utility model provides a bolt suitable for ultrasonic wave nondestructive test, includes the nut, takes screwed screw rod portion, the outer terminal surface of nut is the burnishing surface, the side of nut is provided with the intaglio sign of concave yield. The beneficial effects of this technical scheme are that can effectively improve bolt ultrasonic testing time measuring efficiency, the probe more makes things convenient for inseparabler and improves information acquisition's the degree of accuracy with the contact of bolt, and the specification code is placed in hexagon bolt's side simultaneously, and the specification code is the recessed foreign language, does not influence the loading and unloading of bolt under the condition of effectively preserving the specification code.
Description
Technical Field
The utility model relates to a bolt mounting field, in particular to bolt suitable for ultrasonic nondestructive test.
Background
Nowadays, the detection of bolts is becoming more and more common for the improvement of safety performance of engineering and machinery. The end parts of the existing bolts and nuts are all provided with specification codes, the difficulty is caused to ultrasonic detection, and the ultrasonic probe can be effectively attached to the bolt for flaw detection only by manually grinding raised lettering. The time and the labor are consumed, and the specification codes are polished off, so that the subsequent bolt specification identification is difficult. For overcoming this difficult problem, the utility model discloses ultrasonic wave bolt, nut end face are level and smooth, and the specification code is placed in the side of bolt, and the specification code is the recessed characters of the shadow. Therefore, the efficiency and the accuracy of ultrasonic detection of the bolt can be effectively improved, the specification code is also effectively stored in the bolt subjected to ultrasonic detection, and the assembly and disassembly of the bolt are not influenced under the condition of effectively storing the specification code. The method can effectively prevent the damage to the bolt codes due to the ultrasonic detection operation and improve the efficiency of nondestructive detection of the bolts.
Disclosure of Invention
For solving the above technical problem, the utility model discloses the technical scheme who takes as follows:
a bolt suitable for ultrasonic nondestructive testing comprises a nut 1 and a threaded screw part 2, wherein the outer end face of the nut 1 is a flat face, and the side face of the nut 1 is provided with a concave intaglio mark 3; it can be optimized that the nut 1 has a regular hexagonal shape.
It can be further optimized that the negative logo 3 is arranged on one side of the hexagonal nut 1.
It is also possible to optimize the negative sign 3 on both sides of the hexagonal nut 1.
It can be further optimized that the inscription marking 3 is arranged on three spaced apart sides of the hexagonal nut 1.
It is further preferred that the negative logo 3 is provided on six sides of the hexagonal nut 1.
A further optimization is that the negative logo 3 is arranged centrally on the side of the screw cap 1.
The beneficial effects of this technical scheme are that can effectively improve bolt ultrasonic testing time measuring efficiency, the probe more makes things convenient for inseparabler and improves information acquisition's the degree of accuracy with the contact of bolt, and the specification code is placed in hexagon bolt's side simultaneously, and the specification code is the recessed foreign language, does not influence the loading and unloading of bolt under the condition of effectively preserving the specification code.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic diagram of the present invention.
Fig. 2 is a schematic diagram of a third embodiment of the present invention.
Wherein: 1. a nut; 2. a screw section; 3. and identifying the yin characters.
Detailed Description
The first embodiment is as follows: the technical solution is described in detail with reference to fig. 1.
A hexagonal bolt suitable for ultrasonic nondestructive testing comprises a nut 1 and a threaded screw part 2, wherein the outer end face of the nut 1 is a flat face, and one side face of the nut 1 is provided with a concave intaglio mark 3;
when the ultrasonic nondestructive test is carried out, the detection surface of the ultrasonic nondestructive detector is leveled with the smooth outer end surface of the screw cap 1, and the ultrasonic nondestructive test is carried out. When needing to know this bolt model, look over the recessed shadow sign in nut 1 side can. Because the mark is arranged in a negative mode, the operation of screwing or unscrewing the bolt by using a tool such as a wrench is not influenced. The negative logo 3 is centrally located on the side of the nut 1.
The second embodiment is as follows:
in order to ensure the use precision of the bolt and keep the force balance, the first embodiment is the same except that the intaglio marks 3 are arranged on two symmetrical side surfaces of the hexagonal nut 1.
The third concrete embodiment: the third embodiment is explained with reference to fig. 2:
in order to ensure the use precision of the bolt and keep the force balance, except that the intaglio marks 3 are arranged on three spaced sides of the hexagonal nut 1, the other embodiment is the same as the first embodiment.
The fourth concrete embodiment: in order to ensure the use precision of the bolt and keep the force balance, the first embodiment is the same except that the intaglio marks 3 are arranged on each side surface of the hexagonal nut 1.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
