The first driving unit 32 and the second driving unit 33 may be linear driving modules, such as servo motor modules, which are common modules in the mechanical field and are not repeated herein.
Under the driving of the first driving unit 32 and the second driving unit 33, the probes 311 can move in the horizontal direction and the vertical direction, and the rotation of the workpiece on the turntable 20 is combined, so that the phased array ultrasonic detection device 1 of the present invention can perform all-directional detection on the workpieces such as gears and gear shafts, and a plurality of groups of detection modules 30 can be arranged according to the detection requirements, and a plurality of probes 311 perform detection simultaneously, thereby greatly improving the detection efficiency. The multiple probes 311 can use different wafers and different scanning routes and parameters, so that comprehensive detection is realized, and the detection efficiency is improved.

Further, as shown in fig. 5, the cushion block 50 is rectangular, the roller 35 is disposed at the bottom of the detection module 30, the cushion block 50 is provided with a trapezoidal groove 51 for accommodating the roller, and when the detection module 30 needs to be lifted up, the detection module 30 is placed on the cushion block 50, so that the cushion block 50 is padded at the bottom of the detection module 30, as shown in fig. 8. The trapezoidal groove 51 is set to be trapezoidal, and the rollers 35 of the detection module 30 can be conveniently placed in the trapezoidal groove 51. The rollers 35 disposed at the bottom of the detecting module 30 facilitate the movement of the detecting module 30.

The spacer 50 is arranged in a grid structure, so that the material can be saved, the weight can be reduced, and the installation is convenient. In addition, the grid structure makes the cushion blocks 50 in a grid shape, so that the specification of the cushion blocks 50 can be conveniently judged according to the number of the grids, for example, the height of one grid is specified, the height of the cushion block 50 can be known by looking at the grids of the cushion blocks 50, and the cushion blocks 50 can be conveniently and quickly selected according to the detection requirement.
Fig. 9 is a schematic structural diagram of the probe unit in the present invention, as shown in fig. 9, in an embodiment, the probe unit 31 includes a beam 312 and an elastic component 313, the probe 311 is fixed at one end of the beam 312, the other end of the beam 312 is mounted on the second driving unit 33 through the elastic component 313, and the elastic component 313 is configured such that when the probe 311 contacts with the workpiece, the beam 312 is pushed against the surface of the workpiece with a buffer under the pulling of the elastic component 313, so as to achieve the buffer and avoid scratching the workpiece.
Further, as shown in fig. 9, the elastic assembly 313 includes a sliding rail 3131, a sliding block 3132, a fixed block 3133, and a spring 3134, the sliding rail 3131 and the fixed block 3133 are disposed on the second driving unit 33, the fixed block 3133 is disposed at the front end of the sliding rail 3131, the sliding block 3132 is fitted on the sliding rail 3131, one end of the spring 3134 is connected to the fixed block 3133, the other end is connected to the sliding block 3132, fig. 9 shows that the spring 3134 is connected to the rear end of the sliding block 3132, and the beam 312 is connected to the sliding block 3132. Since the sliding rail 3131 and the fixed block 3133 are fixedly disposed on the second driving unit 33, the sliding block 3132 can slide on the sliding rail 3131, the cross beam 312 is fixed on the sliding block 3132, and can also slide on the sliding rail 3131, when the probe 311 at the front end of the cross beam 312 contacts with the workpiece, the probe 311 pushes against the workpiece, the cross beam 312 receives the pushing force of the workpiece, the cross beam 312 pushes the cross beam 312 to move backward, the cross beam 312 drives the sliding block 3132 to slide, so that the spring 3134 fixed on the sliding block 3132 is deformed, the spring 3134 is deformed to generate a pulling force of a recoil, and the cross beam 312 is pulled forward, so that the cross beam 312 is pushed against the surface of the workpiece under the action of the elastic force, and buffering is.
Referring to fig. 9, in order to achieve good coupling between the probe 311 and the workpiece, a spray header 3121 may be disposed on the beam 312, the spray header 3121 is used for pre-spraying the workpiece, the spray header 3121 is mounted on the beam 312 through a mounting block 3122 and located at the rear of the probe 311, and a liquid supply device 60 for providing a coupling agent to the spray header 3121 is connected to the rear end of the spray header 3121, as shown in fig. 5, the liquid supply device 60 includes a liquid filtering system, so that the coupling agent delivered to the spray header 3121 is filtered without affecting detection. In the prior art, a nozzle is arranged on a wedge 3111 at the front end of a probe 311, and the wedge 3111 directly contacts with a workpiece, so that the nozzle directly sprays against the workpiece, which causes that the pressure sprayed on the surface of the workpiece is too large, and the gap between the wedge 3111 and the surface of the workpiece is enlarged, thereby affecting the inspection sensitivity. According to the invention, the spray head 3121 is arranged on the beam 312 and behind the probe 311 for pre-spraying, so that the gap between the wedge 3111 and the workpiece surface is not increased.
Further, as shown in fig. 1, a liquid tank 70 may be further disposed on the workpiece table 10 below the rotary table 20, and the liquid tank 70 is used for accommodating the coupling agent sprayed from the spray header 3121, so as to prevent the coupling agent from flowing everywhere. A valve can be arranged below the liquid tank 70, and when the coupling agent in the liquid tank 70 is excessive, the valve is opened to discharge so as to prevent overflow.
