Description
Technical Field
The utility model relates to a handheld eddy current flaw detector auxiliary detection device.
Background
The technical requirements of the roller and other like products specify that the roller body surface cannot have any crack defects. Since many types of cracks are too small to be directly observed by naked eyes, and the surface area of the outer circle of the roller is large and difficult to detect, the eddy current inspection mode is generally adopted to detect the cracks on the surface of the outer circle of the roller. The existing detection modes mainly comprise two modes, one mode is that the grinding machine is provided with eddy current flaw detection, although the detection area is large and the speed is high, the equipment is expensive and easy to damage, the equipment maintenance cost is high, the direct and accurate positioning cannot be realized in the detection process, and the position of a detected crack has deviation; secondly, the manual hand-held eddy current flaw detection has the advantages of simple equipment, high reliability and low equipment cost and maintenance cost, compared with the two methods, the manual hand-held eddy current flaw detector is mostly selected to carry out crack detection on the surface of the roller in consideration of cost, actual use requirements and measurement precision requirements, but the manual detection mode has the advantages of small detection area, long detection time and large influence on detection precision by personnel operation.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: in order to overcome not enough among the prior art, the utility model provides a supplementary detection device of handheld eddy current flaw detector to on the basis that detects is accomplished to high efficiency, reduce personnel's operation influence, improve roll detection area and detection precision.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a handheld eddy current flaw detector auxiliary detection device, installs in making the rotatory roll body side of circumference, has the transverse guide of parallel roll axis, transverse guide on roll and be equipped with the guide rail dolly, the detecting head of eddy current flaw detector is installed on the guide rail dolly and is pressed close to roll body surface, eddy current flaw detector and detecting head line connection.
Furthermore, in order to conveniently adjust the test length of the transverse guide rail and meet the detection requirements of rollers with different degrees, two ends of the transverse guide rail are respectively provided with a vertical support rod with scales, and the transverse guide rail is adjustably connected with the vertical support rods through a cross slide block and is fixed by a set screw after being adjusted in place.
In order to stably support the transverse guide rail, the lower end of the vertical stay bar is connected with a magnetic gauge stand.
In order to facilitate the speed regulation and control of the guide rail trolley, the guide rail trolley is driven by a variable speed motor and can be remotely controlled,
the utility model has the advantages that: the utility model discloses a detecting head along with the removal of rail trolley on transverse guide, can realize the total coverage of roll shaft area of measurement, single-person operation can accomplish the measurement process, and the operator only needs to hold eddy current flaw detector and pays close attention to instrument display, simple structure, convenient to use.

Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic view of the installation of the cross-rails.
In the figure: 1. the device comprises a transverse guide rail, 2. a guide rail trolley, 3. an eddy current flaw detector, 4. a detecting head, 5. a vertical supporting rod, 6. a cross sliding block, 7. a set screw, 8. a magnetic gauge stand and 9. a roller.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
The auxiliary detection device of the handheld eddy current flaw detector shown in fig. 1 and 2 is installed close to the side surface of a roller body of a roller 9 which rotates circumferentially, and comprises a pair of magnetic gauge bases 8 which are arranged on an adsorbable detection platform at a distance, vertical support rods 5 with scales are fixed on the magnetic gauge bases 8, transverse guide rails 1 which are positioned between the vertical support rods 5 and parallel to the axis of the roller 9 are arranged, and two ends of each transverse guide rail 1 are adjustably connected with the vertical support rods 5 through cross sliding blocks 6 and are fixed through set screws 7 after being adjusted in place. The length of the transverse guide rail 1 can be adjusted so as to conveniently select the most suitable detection length, and a plurality of groups of transverse guide rails 1 with different lengths can be used for replacement.
The transverse guide rail 1 is provided with a guide rail trolley 2 in a rolling manner, the guide rail trolley 2 is driven by a variable speed motor so as to be convenient to adjust to a proper moving speed, and the speed is kept constant in the moving process, so that different transverse moving speeds are set according to different rotating speeds, and the roller body surface of the roller 9 is ensured to have no leakage part; meanwhile, the guide rail trolley 2 can be remotely controlled by a remote controller, so that the speed can be conveniently set and the guide rail trolley can be started and stopped at any time, once crack signals twinkle are found on the display screen of the eddy current flaw detector 3, the guide rail trolley can be stopped in time, and continuous detection is continuously carried out at the position to repeatedly confirm and position the guide rail trolley.
The detecting head 4 of the eddy current flaw detector 3 is arranged on the guide rail trolley 2 and is close to the surface of the roller body of the roller 9, the eddy current flaw detector 3 is connected with the detecting head 4 through a line, the transverse movement of the guide rail trolley 2 on the transverse guide rail 1 is utilized to replace artificial transverse movement, and an operator can be concentrated on the display on the screen of the eddy current flaw detector 3 without distraction.
The utility model discloses can realize that 9 roll shaft measuring area of roll covers entirely, do not have and lose hourglass, single can accomplish the measurement process, the operator only need hand eddy current flaw detector 3 focus on the instrument display can. Simple structure, good measurement repeatability and quick positioning.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
