Background technology
The application in the industry today of shaft-disc-like workpiece is very extensive, contains the numerous areas such as building, machinery, manufacture, automobile, Aero-Space.For the detection of internal defects, evaluation workpiece quality, improvement product manufacture, reduction industrial accident occurrence probability are had great importance.
Ultrasound wave in the material propagation distance is long, be inherent vice main detection means it.When ultrasound wave enters shaft-disc-like workpiece, if existing defects ultrasound wave will reflect at this place, reflection wave is converted to electric signal and is presented on video screen after receive MUT.The shortcoming of manual inspection is that efficiency is too low and easily undetected and flase drop occurs, and considering can the mechanical scanner of design specialized, carries out scanning to shaft-disc-like workpiece, data processing is carried out by computing machine, reach the robotization of testing process, both improve detection efficiency like this, turn improve reliability.
Its version of failure detector being applied to shaft-disc-like workpiece mostly at present is: (1) probe maintains static, and workpiece one side is rotated one side and advanced; (2) probe rotates, these two kinds of modes of workpiece straight ahead.But the two applicability all for the large heavier work pieces of diameter of non-large-lot production is not strong, this is because major diameter heavier work pieces rotates and rectilinear motion all needs special large scale positioning clamping device, and corresponding propulsion system need be provided, equipment needed thereby expense cost is high and to take place, workshop many.On the other hand, the scanning equipment that the shaft-disc-like workpiece as variable diameters of detecting a flaw uses at present regulates difficulty, very flexible.
For diameter heavier greatly with the shaft-disc-like workpiece of variable diameters, overcome that current failure detector applicability is strong, device structure is complicated, cost is high, adjustment is difficult, the shortcomings such as poor reliability, provide a kind of Novel ultrasonic failure detector that can overcome deficiency to be at present to greatest extent very significant.
Summary of the invention
The object of the present invention is to provide a kind of reflectoscope of non-uniform shaft disc type work, failure detector relies on motor to drive probe to do circular motion and upper and lower vertical movement, is widely used in the flaw detection of various non-uniform shaft disc type work.This apparatus cost is low, structure simple, strong adaptability, and use procedure is keeped in repair less, automaticity is high.
The object of the invention is to be achieved through the following technical solutions:
Non-uniform shaft disc type work failure detector comprises left slide unit, coupling block, arc guide rail, probe holder, probe, stepper motor, right slide unit, it is characterized in that, probe can be close to shaft-disc-like surface of the work and carry out inside flaw detection to inside workpiece defect; Probe is installed on probe holder; Probe holder can be moved in a circle by driving stepper motor on arc guide rail.Arc guide rail is connected by coupling block and left slide unit and right slide unit, driving stepper motor ball screw turns in right slide unit, make the joining coupling block knee-action with ball-screw, thus drive probe holder to realize the lifting action of vertical direction, ensure that probe is detected a flaw to the multidiameter of different-diameter size.Probe does circumferential movement along arc guide rail and can guarantee to detect that the whole defect of inside workpiece does not stay flaw detection dead angle.
Described non-uniform shaft disc type work failure detector, is equipped with pinion wheel in the middle of probe holder, is rotated by driving stepper motor pinion wheel on the arc-shaped rack of arc guide rail, thus drives probe holder to rotate along arc guide rail.Can probe holder be driven to rotate and reverse by Driving Stepping Motor, and according to detecting the factors such as the material of workpiece and diameter and regulate the speed of probe holder motion, to guarantee the accuracy that detects and high-level efficiency.
Described non-uniform shaft disc type work failure detector, arc guide rail used is double V-shaped guide rail, respectively has two pair rollers up and down and specify its rigging position at guide rail, to ensure the balance of probe holder and to realize along arc guide rail level and smooth mobile without impact.
Described non-uniform shaft disc type work failure detector, arc guide rail is connected by coupling block and left slide unit and right slide unit, and probe holder is by driving stepper motor along the upper and lower rectilinear motion of ball-screw, and this ball-screw need have auto-lock function.
Advantage of the present invention and effect are:
1. the non-uniform shaft disc type work failure detector equipment of the present invention's proposition, can realize the flaw detection of the axle class to different-diameter, dish class, tubing, dirigibility is good and applicability is wide;
2. the failure detector that the present invention proposes can not carry out Site Detection when carrying large workpiece to it, overcomes checkout equipment device needed for large-scale workpiece large, the shortcoming that power consumption is high and occupied ground is large, and this apparatus cost is cheap, and cost performance is good;
3. the failure detector that the present invention proposes can realize detecting for some on-the-spot in-service equipment, does not need to be shut down and dismantle, has the advantages that to save production run cost;
3. the present invention can coordinate automated detection system, improves its detection accuracy and efficiency.
