Referring to fig. 1, the utility model provides an ultrasonic detection device for rod whole section is detected a flaw, it includes drive mechanism 1, ultrasonic detection mechanism 2, circulating water mechanism 3 and a plurality of transfer mechanism 4. The rod body 5 can be placed on the transmission mechanism 1, can be automatically placed by an external manipulator, and can also be manually placed; the ultrasonic detection mechanism 2 is provided with an inlet end 21 and an outlet end 22; one side of the inlet end 21 is provided with a transmission mechanism 1; the ultrasonic detection mechanism 2 can receive the rod 5 conveyed by the transmission mechanism 1 and can detect flaws on the whole rod 5; the circulating water mechanism 3 is arranged below the ultrasonic detection mechanism 2 and can supply water into the ultrasonic detection mechanism 2; the circulating water mechanism 3 can enable the rod body 5 to be completely soaked in the ultrasonic detection mechanism 2; the relay mechanism 4 is disposed at one side of the outlet end 22.
The utility model discloses a drive mechanism 1 can push away ultrasonic detection mechanism 2 with barred body 5, can cooperate ultrasonic detection mechanism 2 to rotate barred body 5 simultaneously, simple structure, practicality. The ultrasonic detection means 2 is provided in the next step of the transmission means 1. The ultrasonic detection mechanism 2 is filled with a coupling agent provided by the circulating water mechanism 3, and the coupling agent of the utility model can be a common flaw detection coupling agent such as water, oil and the like; even when the rod 5 passes through the ultrasonic detection mechanism 2, a large amount of couplant can not be lost, so that the rod 5 can be completely soaked in the ultrasonic detection mechanism 2, the generation of bubbles during flaw detection can be reduced, and the flaw detection can be performed on the whole section of the rod 5. Secondly, there is a time difference between the entrance end 21 of the rod 5 and the ultrasonic detection mechanism 2 when the rod 5 enters the ultrasonic detection mechanism for flaw detection, so that the generation of air bubbles is further reduced, and the measurement accuracy is improved. The relay mechanism 4 is provided in the next step of the ultrasonic detection mechanism 2. The relay mechanism 4 can move the rod 5 and can rotate the rod 5 to butt the rod 5 conveyed by the ultrasonic detection mechanism 2.
As shown in fig. 2, the ultrasonic detection mechanism 2 further includes a case 23, a probe 25, a pair of baffle assemblies, a plurality of second motors (not shown), and a plurality of rollers 24; the interior of the box body 23 is a hollow structure, and the inlet end 21 and the outlet end 22 are respectively arranged on the side wall of the box body 23; the inlet end 21 and the outlet end 22 are circular through holes with the same inner diameter and can be in clearance fit with the rod 5 so as to reduce the loss of the couplant when the rod 5 passes through the inlet end 21 or the outlet end 22, and therefore, the rod 5 can be completely soaked in the couplant; the axes of the inlet end 21 and the outlet end 22 are coincident with the axis of the rod 5; the plurality of rollers 24 are arranged in the box body 23 and are uniformly distributed along the periphery of the circumference of the through hole; the rotating roller 24 is connected with an output shaft of a second motor; the probe 25 is arranged in the box body 23 and close to the outlet end 22, and preferably, the probe 25 is vertically arranged right above the rod body 5; the inlet end 21 and the outlet end 22 are respectively provided with a pair of shutter assemblies which are opened when abutting against the rod 5 and closed when being separated from the rod 5.
Specifically, a rotating shaft 241 is arranged in the rotating roller 24, one end of the rotating shaft 241 is connected with an output shaft of the second motor through a coupler, and the other end of the rotating shaft 241 is connected with a bearing seat; preferably, neither the bearing seat nor the second motor is disposed on the box 23, and may be disposed on another rigid member, so as to reduce the vibration generated when the roller 24 rotates, and further improve the detection accuracy of the probe 25. Secondly, when the conventional rod 5 is used for flaw detection, a spray head is mostly arranged above the probe 25 so as to temporarily provide a coupling agent for a gap between the probe 25 and the rod 5 and perform flaw detection; however, since the couplant is temporarily ejected from the head while the rod 5 is rotating, bubbles are inevitably generated in the gap between the probe 25 and the rod 5, and the bubbles cause the ultrasonic waves emitted from the probe 25 to return in advance, thereby causing erroneous judgment of the defect of the rod 5. The probe 25 of the utility model is arranged near the outlet end 22, and in the time period from the inlet end 21 to the position near the probe 25 of the rod 5, the rod 5 is pushed by the transmission mechanism 1 to move, and the roller 24 drives the rod 5 to rotate; in this period, namely, before the flaw detection of the rod 5, most of the bubbles are eliminated as much as possible by soaking the couplant and rotating the rod 5, thereby improving the flaw detection precision. And because the rod body 5 and the probe 25 are completely soaked in the couplant, the probe 25 does not need to be abutted against the rod body 5, and the probe 25 can finish flaw detection even if a certain distance is kept, so that the abrasion of the probe 25 is reduced, the service life of the probe 25 is prolonged, and the measurement precision is improved.
Referring to fig. 2 and 3, the barrier assembly includes a barrier 26, a torsion spring (not shown), and a connection plate 27; the baffle 26 is arranged in the inlet end 21 or the outlet end 22, one side of the baffle 26 close to the box body 23 is fixedly connected with a connecting plate 27, and the connecting plate 27 is hinged with the inner wall of the box body 23; the torsional spring sets up on the hinge bar, the one end and the baffle 26 butt of torsional spring, the other end of torsional spring and the inner wall butt of box 23. The number and the type of the torsion springs can be selected according to actual requirements because the elasticity of the torsion springs is related to the extrusion force borne by the rod body 5 and the opening or closing speed of the baffle.
Further, the thickness of the baffle 26 is smaller than the thickness of the end plate at the inlet end 21 or at the outlet end 22, i.e., the thickness of the side wall of the box 23 in the moving direction of the rod 5; the mounting groove has been seted up on the one side of the end plate keeping away from drive mechanism 1, and connecting plate 27 articulates in the mounting groove, and the mounting groove is L type groove to carry on spacingly to the rotation stroke of baffle 26. Specifically, before the rod abuts against the baffle 26 at the inlet end 21, the rod 5 is in clearance fit with the inner wall of the box 23; when the rod 5 abuts against the baffle 26 at the inlet end 21, the baffle 26 is pushed open by the rod 5, and since the rod 5 is already in clearance fit with the inner wall of the box 23, a large amount of couplant is not lost. The same applies to the case where the rod 5 abuts the baffle 26 at the outlet end 22. In addition, when the rod 5 is separated from the baffle 26 at the inlet end 21, the torsion spring can act on the baffle 26 to rapidly close the baffle 26, so as to reduce the outflow of the couplant, thereby prolonging the flaw detection times of the rod 5. The same applies when the rods 5 are separated from the baffles 26 at the outlet end 22.
Next, a plurality of balls 261 are provided on the side of the baffle 26 close to the transmission mechanism 1. Specifically, when the rod 5 enters the box 3, the theoretical position of the baffle 26 is parallel to the axial direction of the rod 5, so that the distance between the bottom surface of the ball 261 above the rod 5 and the top surface of the ball 261 below the rod 5 preferably coincides with the outer diameter of the rod 5. Wherein the distance between the upper and lower balls 261 can be set by the hinge position of the connection plate 27. Through the cooperation of ball 261 and commentaries on classics roller 24, can carry out spacing in the vertical direction to barred body 5 to reduce the vibration that produces on barred body 5 surface when probe 25 detects a flaw, and then improve measurement accuracy.
Further, the box body 23 is provided with a water inlet 231 and a water outlet 232, and both the water inlet 231 and the water outlet 232 are communicated with the circulating water mechanism 3; the water inlet 231 is disposed adjacent to the inlet end 21 and above the inlet end 21. Preferably, the water inlet 231 is disposed obliquely above the inlet end 21 to prevent air bubbles generated when the coupling agent enters the box 23 through the water inlet 231 from affecting the flaw detection of the probe 25.
Next, the circulating water mechanism 3 includes a water tank, a water pump (not shown), a water supply pipe (not shown), and a water discharge pipe (not shown); the water tank is arranged below the tank body 23; the water pump is arranged in the water tank and is communicated with a water supply pipe, and the other end of the water supply pipe is communicated with the water inlet 231; the drain pipe communicates the water outlet 232 with the water tank.

Preferably, the first supporting seat 18 is provided with balls, and the transmission mechanism 1 is provided with the balls and the ejector pins 16 to adapt to the rotation of the rod 5 driven by the roller 24.
Referring to fig. 6, the transfer mechanism 4 includes a mounting seat 41, a third motor 42, a second lead screw 43, a third fixing seat 44, a plurality of second sliding blocks 45, and a plurality of second supporting seats 46; the mounting seat 41 is arranged on one side of the outlet end 22, the third motor 42 is arranged on the mounting seat 41, an output shaft of the third motor 42 is connected with a second lead screw 43, the other end of the second lead screw 43 is rotatably connected with a third fixing seat 44, a plurality of second sliding blocks 45 are rotatably connected with the second lead screw 43, the bottom ends of the second sliding blocks 45 are abutted to the mounting seat 41, and a plurality of second supporting seats 46 are arranged on the second sliding blocks 45. Specifically, the transfer mechanism 4 can receive the rod 5 conveyed from the ultrasonic detection mechanism 2, and can not only adapt to the rotation of the rod 5, but also drive the rod 5 to move. The utility model discloses a transfer mechanism 4 can cooperate with 16, the commentaries on classics roller 24 of thimble, can link up the transportation of barred body 5 between the upper and lower process perfectly to guarantee barred body 5 at the stability of removal in-process, and then increase the precision of detecting a flaw.
The transfer mechanism 4 can directly unload materials, and can be taken manually or by an external manipulator; the subsequent step may be performed later. It should be noted that, when the first sliding block 15 of the transmission mechanism 1 reaches the stroke limit, that is, when the distance from the first sliding block 15 to the first motor 12 is the farthest, the right end of the rod 5 needs to be moved into the transfer mechanism 4, and the rod 5 is driven by the second supporting seat 46 instead of being pushed by the thimble 16; and when the first slide block 15 reaches the stroke limit, the thimble 16 is always positioned outside the box body 23.
