Abstract
The invention discloses ultrasonic gas valve inspection equipment, which comprises a box body, a stepping motor, a motor driver, an ultrasonic flaw detector, an industrial personal computer, a switchover interface and a hopper-shaped sealing cover. The stepping motor and the motor driver are arranged at the bottom of the box body; the ultrasonic flaw detector is used for detecting defects of a gas valve; the industrial personal computer coordinately controls different components; the switchover interface is connected between the industrial personal computer and the ultrasonic flaw detector; the hopper-shaped sealing cover is hermetically arranged above the stepping motor; a rotating shaft of the stepping motor penetrates through the center of the sealing cover; the gas valve to be detected is arranged above the sealing cover and is detachably connected with the rotating shaft of the stepping motor; and water is filled in a concave surface of the sealing cover. A water immersion ultrasonic penetration method is adopted, and tiny defects in a surfacing layer can be sensitively detected. Practice proves that the method has reliable sensibility. Air holes and cracks with diameters of more than 0.3mm in a cone surface range can be detected; and air holes with the diameters of 0.20mm in a cone, cone surfacing and incomplete fusion and stratification of base materials can be detected.
Description
Technical field
the present invention relates to inspection field, particularly a kind of ultrasound wave air valve inspection machine.
?
Background technology
internal-combustion engines vehicle is a ultrasonic detection method with the optimal lossless detection method of inlet and outlet valve sealing surface quality testing.The detection of defective in the Diesel Engine's Air Valve overlay cladding mainly is definite effect that could obtain to detect in which way.Because the shape of its umbrella shape and high to the detection sensitivity requirement of defective in the whole bag of tricks of Non-Destructive Testing, all adopts single method for reflection to carry out ultrasound examination at present; Because workplace is very little; The difficulty that detects is very big, and loss is very high, is to be difficult to both at home and abroad solve always.
?
Summary of the invention
the purpose of this invention is to provide the ultrasound wave air valve inspection machine that a kind of loss is low and degree of accuracy is high.
are for solving the problems of the technologies described above; The present invention adopts following technical scheme: a kind of ultrasound wave air valve inspection machine it comprise casing, be arranged on bottom half stepper motor and motor driver, be used to detect the air valve defective ultra-sonic defect detector, coordinate each parts of control industrial computer, be connected translation interface between industrial computer and the ultra-sonic defect detector, be sealed in the infundibulate gland bonnet of stepper motor top; Described stepper motor rotating shaft is located in the gland bonnet center; Air valve to be detected is arranged on the gland bonnet top and removably connects with the stepper motor rotating shaft, is marked with water in the concave surface of described gland bonnet.
ultra-sonic defect detector comprises ultrasound wave display, transmitting probe and accepts probe, and described transmitting probe is arranged on the top of air valve sealing face, and described acceptance probe is arranged on the below of air valve sealing face and relative with transmitting probe.
beneficial effect of the present invention is: the present invention adopts water logging penetration of ultrasound waves method, can compare the sensitive tiny flaw in the overlay cladding that detects.This method is confirmed in practice process, and its sensitivity is reliable.Conical surface can reach a diameter greater than 0.3mm within pores and cracks; tapered hole inside diameter is larger than 0.20mm and detecting tapered surface of the base material is not deposited Yong He and stratification.

Embodiment
Below in conjunction with accompanying drawing the present invention is made following detailed description:
are for solving the problems of the technologies described above; The present invention adopts following technical scheme: a kind of ultrasound wave air valve inspection machine it comprise casing 1, be arranged on casing 1 bottom stepper motor 2 and motor driver 3, be used to detect the air valve defective ultra-sonic defect detector, coordinate each parts of control industrial computer 5, be connected translation interface 6 between industrial computer 5 and the ultra-sonic defect detector, be sealed in the infundibulate gland bonnet 7 of stepper motor 2 tops; Described stepper motor 2 rotating shafts are located in gland bonnet 7 centers; Air valve to be detected is arranged on gland bonnet 7 tops and removably connects with stepper motor 2 rotating shafts, is marked with water in the concave surface of described gland bonnet 7.
ultra-sonic defect detector comprises ultrasound wave display 41, transmitting probe 42 and accepts probe 43; Described transmitting probe 42 is arranged on the top of air valve sealing face, and described acceptance probe 43 is arranged on the below of air valve sealing face and relative with transmitting probe 42.
this checkout equipment uses probe to be Φ 4mm, 10MHZ.Receiving transducer is the flat sided straight probe.Transmitting probe is a point focusing probe.After probe moves to detecting position by pneumatic mechanism, could adjust probe, the reception plane of probe is adjusted to parallel with sealing surface of air valve, and distance gets final product between 5 ~ 8mm.And transmitting probe 1 needs an incident angle θ during adjustment, and the θ value is confirmed by the oblique angle α of sealing surface of air valve, can be confirmed by computes:
Θ=Sinˉ'(C1/C2?Sinα)…………(1)
In the formula: the longitudinal wave velocity of C1-couplant (water);
The longitudinal wave velocity of C2-valve material;
The oblique angle of
α-sealing surface of air valve.
the foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
