Existing ultrasonic flaw detection of bars is mainly divided into manual flaw detection and automatic equipment flaw detection. Manual flaw detection is only suitable for small areas or special-shaped materials, while automatic equipment can place bars on a rotating roller group for automatic detection.

[0003] At present, after the automatic inspection equipment detects a bar, it needs to be removed from the rotating roller group and then transported to the rotating roller group. During the replacement of the bar, the ultrasonic flaw detection equipment stops working. When facing a large number of bar inspections, the ultrasonic flaw detection equipment stops working for a long time, which leads to low inspection efficiency and difficulty in meeting mass production needs. Therefore, there is an urgent need for a bar ultrasonic flaw detection device to solve the above problems. Utility Model Content

[0023] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] Example 1

[0025] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a rod ultrasonic flaw detection device, which includes a placement frame 1, a rotating frame 2 is provided on one side of the placement frame 1, a circular plate 3 is fixedly connected to the rotating frame 2, a notch 301 is opened on the circular plate 3, driving rollers 4 are rotatably connected on both sides of the notch 301, and a flaw detection mechanism 5 is installed between the two circular plates 3. The placement frame 1 is used to place the rods to be tested. When the rod closest to the support frame 2 falls into the notch 301, the circular plate 3 drives the rod to rotate and displace as a whole, and the flaw detection mechanism 5 performs flaw detection on the rod.

[0026] The flaw detection mechanism 5 includes a connecting seat 501 fixedly connected to the circular plate 3, a reciprocating screw 502 is rotatably connected between the two connecting seats 501, one end of the reciprocating screw 502 is driven by a second motor 503, a moving seat 504 is slidably connected to the reciprocating screw 502, an ultrasonic probe 505 is installed on the moving seat 504, and one end of the reciprocating screw 502 is transmission-connected to the driving roller 4 through a chain. In the above technical scheme, the second motor 503 drives the reciprocating screw 502 to rotate, and the reciprocating screw 502 drives the driving roller 4 to rotate, so that the two radial driving rollers 4 cooperate to drive the rod to rotate in the notch 301, and at the same time, the reciprocating screw 502 drives the moving seat 504 to move back and forth horizontally, so that the ultrasonic probe 505 performs flaw detection on the rod.

[0027] In actual work, the two axially arranged driving rollers 4 are coaxially connected via a coupling, so that the driving rollers 4 on the two circular plates 3 rotate synchronously, thereby improving the stability of the rod during rotation.

[0028] The top surface of the placement rack 1 is horizontally arranged, and a slope is provided on the side of the placement rack 1 facing the rotating rack 2. The rod to be tested can be placed on the plane of the placement rack 1, and the rod close to the slope can roll along the slope toward the side of the support rack 2 until it contacts the circular plate 3. When the notch 301 faces the rod, the rod rolls into the notch 301.

[0029] The rotating frame 2 includes a rotating roller 201, both ends of which are rotatably connected to a support seat 202, a motor 203 is fixedly installed on the support seat 202, and the motor 203 is used to drive the rotating roller 201 to rotate. The motor 203 drives the rotating roller 201 to rotate, and the rotating roller 201 drives the two circular plates 3 to rotate synchronously.

[0030] A motor base is fixedly mounted on one end of the rotating roller 201, and the second motor 503 is fixedly mounted on the motor base.

[0031] Guide rods 506 connected and fixed to the connecting seat 501 are symmetrically provided on both sides of the reciprocating screw rod 502, and the movable seat 504 is slidably matched with the guide rods 506. A sliding sleeve slidably matched with the reciprocating screw rod 502 is fixed on the movable seat 504. The setting of the guide rods 506 limits the movable seat 504 so that the movable seat 504 can slide horizontally.

[0032] It can be understood that when the notch 301 is located at the inclined surface of the placement rack 1 and rotates one circle, the movable seat 504 moves from one end to the other end on the reciprocating screw rod 502 .

[0033] In actual work, the motor 201 and the ultrasonic probe 503 both rotate with the circular plate 3. The connecting wires of the motor 201 and the ultrasonic probe 503 can be connected to an external power supply through a conductive slip ring at the axis of one end of the rotating roller 201 to avoid the wires from being entangled during rotation.

[0034] Reference Figure 2 A guide frame is provided on one side of the support frame 2 away from the placement frame 1. When the notch 301 is inclined toward the lower side of one side of the guide frame, the rod in the notch 301 can roll out of the circular plate 3 along the guide frame.

[0035] It can be understood that the placement frame 1, the support frame 2 and the guide frame are all installed and fixed to the ground at the same level by bolts and other tools, so as to improve the stability of the equipment during operation.

[0036] During use, the rod to be tested can be placed on the plane of the placement rack 1, and the rod close to the inclined surface can roll along the inclined surface toward the side of the support rack 2. The motor 1 201 drives the rotating roller 201 to rotate. When the notch 301 is located at the inclined surface of the placement rack 1, the rod on the inclined surface can roll into the notch 301. The motor 2 503 drives the reciprocating screw 502 to rotate, and the reciprocating screw 502 drives the driving roller 4 to rotate, so that the two radial driving rollers 4 cooperate to drive the rod to rotate in the notch 301. At the same time, the reciprocating screw 502 drives the moving seat 504 to move back and forth horizontally, so that the ultrasonic probe 505 performs flaw detection on the rod.

[0037] Example 2

[0038] Reference Figure 1 , Figure 5 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that a conveyor belt 6 is rotatably connected to the inner side of the placement rack 1, and the conveyor belt 6 is transmission-connected to the circular plate 3 through a transmission member 7. The top surface of the conveyor belt 6 is slightly higher than the top surface of the placement rack 1, so that the conveyor belt 6 can move the rods when rotating, so that the rods are transported to the side of the support frame 2.

[0039] The transmission member 7 includes a worm wheel 701 fixedly connected to a synchronous roller of the conveyor belt 6, a worm 702 meshingly connected to one side of the worm wheel 701, the worm 702 is rotationally connected to the placement rack 1, and a gear 703 is fixedly connected to one end of the worm 702, an arc-shaped rack 8 is fixedly connected to a circular plate 3, and the gear 703 meshes with the arc-shaped rack 8 for transmission. When the plate in the notch 301 rolls down along the guide frame, the arc-shaped rack 8 meshes with the gear 703, and the worm 702 drives the worm wheel 701 to rotate the conveyor belt 6 to a certain angle, and the conveyor belt 6 drives the rod to move.

[0040] It is understandable that each time the arc-shaped rack 8 meshes with the gear 703, the rotation distance of the conveyor belt 6 is the same as the diameter of the rod, so that each time the conveyor belt 6 rotates, it can drive the rod closest to the support frame 2 to roll to one end of the inclined surface.

[0041] The remaining structures are the same as those of Example 1.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
