The bracket provided by the invention can effectively control mechanical clearance and coupling gap between a probe and the roller surface, and provide buffer for the probe during beating of the roller, so as to avoid locking of the flaw detection arm on the roller and ensure the accuracy of the roller flaw detection.
Description
Technical field
The present invention relates to a kind of contact four-way ultrasonic probe support for roll flaw detection.
Background technology
Roll is the indispensable steel rolling instruments of mill milling steel, and roller surface the level and smooth quality to steel in System on Rolling Steel plays a key effect, and therefore uses after some cycles at roll, needs breaker roll surface to carry out reconditioning.But it is in use unavoidable that the generation of roller surface, shallow cosmetic bug is roll, so after coping roller completes, must adopt ultrasound wave to carry out nondestructive examination in breaker roll surface, to guarantee roll quality.
In coping roller process, roll is put has certain degree of tilt, and in rotary course, has certain jerk value, and the degree of tilt of roll and jerk value bring certain impact to the use of ultra-sonic defect detector, cannot guarantee the accuracy of result of detection.Therefore, need a kind of probe bracket that can make up degree of tilt, jerk value to guarantee the accuracy of result of detection.
General defectoscope adopts with the flaw detection arm anchor ear of popping one's head in roll, probe is implemented flaw detection operation against roller surface, because the inclination of coping roller process is rotated, the mechanical clearance of roller surface and detecting head surface, coupling gap cannot be guaranteed, affect result of detection; Simultaneously the arm that makes to detect a flaw of beating of roll easily causes locking phenomenon in testing process, the normal operation of the arm that cannot guarantee to detect a flaw.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of contact four-way ultrasonic probe support for roll flaw detection, utilize this support can effectively control mechanical clearance and the coupling gap of probe and roller surface, and in the time that beating, roll make probe cushion to some extent, avoid the detecting a flaw locking phenomenon of arm breaker roll, has guaranteed the accuracy of roll flaw detection.
For solving the problems of the technologies described above, the present invention comprises flaw detection arm contiguous block for the contact four-way ultrasonic probe support of roll flaw detection, roll surface saddle, fixed block, four buffer springs, four fastening bolts and some rollers, described flaw detection arm contiguous block is positioned at described roll surface saddle top, described fixed block is positioned at described roll surface saddle, described four buffer springs respectively interval are located between described flaw detection arm contiguous block and roll surface saddle and between described fixed block and roll surface saddle, described fixed block is vertically interval with respectively four through holes, one side along continuous straight runs of described fixed block is provided with four screws and is communicated with respectively described four through holes, described four fastening bolts are twisted respectively in described four screws, described some rollers are located at respectively described roll surface saddle and fixed block bottom surface.
Further, above-mentioned rollers is six, and wherein four rolling is located at the both sides of described roll surface saddle bottom surface in interval respectively, and wherein two rollers are located at described fixed block bottom surface in interval respectively.
Further, above-mentioned roll surface saddle end face is provided with through hole.
Because the present invention has adopted technique scheme for the contact four-way ultrasonic probe support of roll flaw detection, the flaw detection arm contiguous block that is this support is positioned at roll surface saddle top, fixed block is positioned at roll surface saddle, four buffer springs are located between flaw detection arm contiguous block and roll surface saddle and between fixed block and roll surface saddle at interval respectively, fixed block is vertically interval with respectively four through holes, one side along continuous straight runs of fixed block is provided with four screws and is communicated with respectively four through holes, four fastening bolts are twisted respectively in four screws, some rollers are located at respectively roll surface saddle and fixed block bottom surface.This support can effectively be controlled probe and mechanical clearance and the coupling gap of roller surface, and in the time that roll is beated, makes probe buffering to some extent, and the locking phenomenon of the arm breaker roll of avoiding detecting a flaw has guaranteed the accuracy of roll flaw detection.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the present invention is described in further detail:
Fig. 1 is the contact four-way ultrasonic probe support structural representation of the present invention for roll flaw detection.
Embodiment
As shown in Figure 1, the present invention comprises flaw detection arm contiguous block 1 for the contact four-way ultrasonic probe support of roll flaw detection, roll surface saddle 2, fixed block 3, four buffer springs 4, four fastening bolts 5 and some rollers 6, described flaw detection arm contiguous block 1 is positioned at described roll surface saddle 2 tops, described fixed block 3 is positioned at described roll surface saddle 2, described four buffer springs 4 respectively interval are located between described flaw detection arm contiguous block 1 and roll surface saddle 2 and between described fixed block 3 and roll surface saddle 2, described fixed block 3 is vertically interval with respectively four through holes 31, one side along continuous straight runs of described fixed block 3 is provided with four screws 32 and is communicated with respectively described four through holes 31, described four fastening bolts 5 are twisted respectively in described four screws 32, described some rollers 6 are located at respectively described roll surface saddle 2 and fixed block 3 bottom surfaces.
Further, above-mentioned rollers 6 is six, and wherein four rolling is located at the both sides of described roll surface saddle 2 bottom surfaces in interval respectively, and wherein two rollers are located at described fixed block 3 bottom surfaces in interval respectively.Roller, for against roller surface, can slide along roller surface whole support.
Further, above-mentioned roll surface saddle 2 end faces are provided with through hole 21.This through hole is for the stube cable between penetrating probe and defectoscope, and the signal between convenient probe and defectoscope is connected.
This support, by four through holes being set on fixed block for fixing four probes, resolves into four probes by an original defectoscope probe, and breaker roll forms the carrying out flaw detection of four-way, effectively improves carrying out flaw detection efficiency.In the time of carrying out flaw detection operation, the roller of this support is positioned at the roller surface of rotation and slides along roller surface, the flaw detection arm of defectoscope connects the flaw detection arm contiguous block of this support, four probes and the guide pin bushing that is coupled of defectoscope are located at respectively in four through holes of fixed block, and can adopt four fastening bolt static probes and coupling guide pin bushing and can adjust respectively the position of four probes and coupling guide pin bushing, to guarantee that the gap between four probes and coupling guide pin bushing and roll surface requires and coupling requirement, thereby obtain result of detection accurately.Detect a flaw between arm contiguous block and roll surface saddle and be connected by buffer spring between fixed block and roll surface saddle; make to form and flexibly connect between any two; in the time of roll generation jumping phenomena; roll surface saddle and fixed block can produce displacement thereupon; play the effect of protection flaw detection arm, the locking of the arm breaker roll of avoiding detecting a flaw.
This supporting structure is simple, installs and detects a flaw easy to operately, has effectively overcome the defect of traditional flaw detection operation, when improving flaw detection operating efficiency, has guaranteed the accuracy of carrying out flaw detection, for the steady operation of defectoscope provides better running environment.
