DETAILED DESCRIPTION

[0015] In order to make the above-mentioned purpose, features and advantages of the utility model more apparent and easy to understand, the specific implementation mode of the utility model is described in detail below with reference to the drawings.

[0016] As Figure 1 and Figure 2As shown in the application, the simple gear ultrasonic flaw detection device provided by the embodiment of the application comprises a water tank 1, a base 2 arranged in the water tank 1, a jig mechanism 3 arranged on the base 2, and a flaw detection mechanism 4 arranged on the base 2. The jig mechanism 3 comprises a mounting seat 31 fixedly arranged on the base 2, a first rotating shaft 32 arranged on the mounting seat 31 with the Z axis as the rotating shaft, a clamping piece 33 arranged at the upper end of the first rotating shaft, a support 34 arranged on the base 2, a second rotating shaft 35 arranged on the support 34, a motor 36 arranged on the support 34 for driving the second rotating shaft 35 to rotate, a driving gear arranged at the lower end of the second rotating shaft 35, a driven gear 38 coaxially fixedly arranged at the lower end of the first rotating shaft 32, and a chain 37 in transmission connection with the driving gear and the driven gear 38.

[0017] It should be noted that the simple gear 6 has an annular weld with a width of 5 mm. The flaw detection mechanism 4 moves 1 mm corresponding to the working end for each rotation of the gear.

[0018] During actual flaw detection, water is filled in the water tank 1 so that the water surface is higher than the simple gear 6. At this time, the flaw detection mechanism 4 is in the working position. Then the second rotating shaft 35 is driven to rotate by the motor 36, the driving gear is driven to rotate, the driven gear 38 is driven to rotate through the chain 37, and the first rotating shaft 32 drives the clamping piece 33 to rotate synchronously. When the clamping piece 33 rotates one circle, the flaw detection mechanism 4 changes the distance from the weld by 1 mm correspondingly, until the flaw detection mechanism 4 completes the flaw detection of each height of the weld.

[0019] In the above design, the structure design and specific implementation of the jig mechanism 3 can realize the rotary driving of the simple gear 6, facilitate the ultrasonic flaw detection of the gear, and reduce the loss of sound wave energy in cooperation with water.

[0020] Specifically, as shown in the application, Figure 1 and Figure 2 The flaw detection mechanism 4 comprises a support 41 arranged on the base 2, a first air cylinder 42 fixedly arranged on the support 41 along the Z axis direction, a first linear module 43 arranged at the output end of the first air cylinder 42 along the horizontal direction, a rotating platform 44 fixedly arranged at the output end of the first linear module 43, a clamping block 45 arranged at the output end of the rotating platform 44, and an ultrasonic probe 46 arranged on the clamping block 45 in an inclined manner. The rotating shaft of the rotating platform 44 is one of the X axis and the Y axis.

[0021] In actual use, the first linear module 43 is driven by the first cylinder 42 to move to a predetermined height, the rotating platform 44 is driven by the first linear module 43 to move to a predetermined position, and the angle of the ultrasonic probe 46 is adjusted by the clamping block 45 driven by the rotating platform 44. When the jig mechanism 3 drives the product to rotate one circle, the ultrasonic probe 46 needs to move 1mm in the water screen direction. That is, the rotating platform 44 is synchronously moved by the first linear module 43, so that the ultrasonic probe 46 moves 1mm along the radial direction of the product, and the flaw detection of different penetration depths is continued.

[0022] In the above design, the structure design and specific implementation of the flaw detection mechanism 4 can effectively realize the accurate movement of the ultrasonic probe 46 to the predetermined flaw detection position.

[0023] Specifically, as shown in Figure 2 , the base 2 is provided with a plurality of handles 5.

[0024] In actual use, the base 2 is moved by gripping the handle 5.

[0025] In the above design, the base 2 can be moved by setting the handle 5, and the movement of the entire flaw detection mechanism 4 and the jig mechanism 3 is realized.

[0026] Specifically, as shown in Figure 1 and Figure 2 , the support 34 includes a first plate 341 fixedly arranged on the base 2, two side plates 342 symmetrically arranged on the base 2, a top plate 343 connected to the upper end faces of the two side plates 342, a third plate 344 and a fourth plate 345 connected to the side plates 342, a third flange bearing 346 arranged on the third plate 344, and a fourth flange bearing 347 arranged on the fourth plate 345, and the second rotating shaft 35 is rotationally connected with the third and fourth flange bearings 346 and 347.

[0027] In the above design, the structure of the entire support 34 supports the top plate 343 by the side plates 342, fixes the two side plates 342 by the first plate 341, the third plate 344 and the fourth plate 345, and reduces the friction of the rotation of the second rotating shaft 35 by the third and fourth flange bearings 346 and 347, so that the assembly of the motor 36 and the second rotating shaft 35 can be stably realized.

[0028] Specifically, as shown in Figure 1 and Figure 2 , the first plate 341 is provided with a horizontally extending first waist-shaped groove 100, the mounting seat 31 is provided with a horizontally extending second waist-shaped groove 200, the first waist-shaped groove 100 and the second waist-shaped groove 200 are parallel, and the base 2 is provided with a first screw hole matched with the first waist-shaped groove 100 and a second screw hole matched with the second waist-shaped groove 200.

[0029] In the above design, the mounting position of the first plate 341 is changed by adjusting the position corresponding to the first waist-shaped groove 100 and the first screw hole, and the position of the mounting seat 31 is changed by adjusting the position corresponding to the second waist-shaped groove 200 and the second screw hole.
