It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0033] Please refer to Figures 1-6 , a casting flaw detection device shown. In order to automatically transfer the castings to be detected to the detection position, a transfer device 1 is provided. The transfer device 1 adopts a chain drive double-row roller conveyor line in the prior art. In order to perform flaw detection on the castings, a flaw detection device 2 is provided, and a rotating device 3 is cooperatively provided to lift and rotate the castings to be detected, facilitating the flaw detection device 2 to detect the castings.

[0034] The rotating device 3 is arranged below the transfer device 1. When the castings are transferred to the position of the rotating device 3 through the transfer device 1, in cooperation with the positioning sensing technology in the prior art, the rotating device 3 lifts and rotates the castings at the same time, enabling the flaw detection device 2 to detect the entire circumference of the castings. Since the flaw detection device 2 has an X-ray detection device to detect the castings, the flaw detection device 2 is a split structure and is arranged on both sides of the transfer device 1.

[0035] The rotating device 3 includes a lifting assembly 3a and a rotating assembly 3b. The lifting assembly 3a is used to lift the rotating assembly 3b, and the rotating device 3 is used to rotate the castings to be detected and their fixing fixtures to perform flaw detection on the four sides of the castings.

[0036] The rotating device 3 is divided into two components. The rotating assembly 3b is used to connect with the fixture for placing the castings and rotate the castings. The lifting assembly 3a is used to lift the rotating assembly 3b and the castings away from the transfer device 1.

[0037] The lifting assembly 3a includes a lifting cylinder 3aa, a lifting bracket 3ab, a fixing plate 3ac, and a guide rod 3ad. The lifting bracket 3ab is arranged on the transfer device 1. The fixing plate 3ac is fixedly arranged at the upper end of the lifting bracket 3ab. The lifting cylinder 3aa is arranged at the lower end of the fixing plate 3ac, and the telescopic rod of the lifting cylinder 3aa passes through the fixing plate 3ac and extends to the upper end of the fixing plate 3ac to be connected with the rotating assembly 3b. The guide rod 3ad is connected with the fixing plate 3ac through a linear bearing.

[0038] The rotating assembly 3b includes a lifting pallet 3ba, a hollow rotating platform 3bb, a suction cup mounting plate 3bc, and an electromagnetic suction cup 3bd. The bottom of the hollow rotating platform 3bb is connected to the telescopic rod of the lifting cylinder 3aa, and the rotating table of the hollow rotating platform 3bb is fixedly connected to the suction cup mounting plate 3bc. The electromagnetic suction cup 3bd is fixedly arranged on the suction cup mounting plate 3bc. The hollow rotating platform 3bb is arranged on the lifting pallet 3ba, and the lower end surface of the lifting pallet 3ba is fixedly connected to the upper end of the guide rod 3ad.

[0039] When the telescopic rod of the lifting cylinder 3aa extends, it jacks up the hollow rotating platform 3bb arranged on the telescopic rod. Then, the electromagnetic suction cup 3bd is attracted to the tooling for placing the casting to achieve temporary fixed combination. The hollow rotating platform 3bb works to drive the electromagnetic suction cup 3bd on the suction cup mounting plate 3bc to rotate, thereby driving the casting placed on the tooling to rotate, realizing the rotation operation of the casting. When the lifting assembly 3a works, the design of the guide rod 3ad is used to increase the stability of the whole process. To ensure the stability of the up and down movement of the rotating device 3b, two groups of guide rods 3ad are arranged in a matrix form on the fixed plate 3ac, and each guide rod 3ad is connected to the fixed plate 3ac through a linear bearing.

[0040] Specifically, the flaw detection device 2 includes floor brackets 2a symmetrically arranged on both sides of the conveying device 1. On each floor bracket 2a, there is a lead screw module 2b and a lead screw and a lead screw module 2c. The lead screw module 2b is arranged vertically and is arranged on the floor bracket 2a. The lead screw module 2c is arranged horizontally, and the outer frame of the lead screw module 2c is fixedly connected to the moving slider of the lead screw module 2b. The flaw detection device 2 also includes an X-ray generator 2d and a flat panel detector 2e. The X-ray generator 2d is arranged on the moving slider of a lead screw module 2c through a fastener, and the flat panel detector 2e is symmetrically arranged with the X-ray generator 2d on both sides of the conveying device 1, and the flat panel detector 2e is fixedly arranged on the moving slider of the other lead screw module 2c.

[0041] In this implementation scheme, the cooperation between the lead screw module 2b and the lead screw module 2c between the two floors can control the up, down, left, and right four-direction movements of the X-ray generator 2d and the flat panel detector 2e, realizing the function of position adjustment.

[0042] Specifically, the X-ray generator 2d and the flat panel detector 2e are electrically connected to the external detection control equipment.

[0043] In this implementation scheme, the X-ray generator 2d and the flat panel detector 2e are electrically connected to the external detection control equipment. Through the external detection control equipment, the detection process can be controlled and the detection results can be observed and obtained.

[0044] Specifically, the device further includes a detection room 4 with a radiation protection function. Both ends of the conveying device 1 extend outside the detection room 4, and the flaw detection device 2 and the rotating device 3 are both arranged inside the detection room 4.

[0045] In this embodiment, the provided side room 4 covers all the main parts of the device, effectively avoiding damage to the human body caused by the X-ray generator 2d.

[0046] Working principle:

[0047] First, the staff places the casting to be detected on the conveying device 1 by manually or using a manipulator to grasp the casting. The casting here is fixed with a special tooling to prevent the casting from shaking or even falling during movement. The tooling here belongs to the conventional design in this technical field and will not be elaborated too much here. When the casting moves to the position of the rotating device 3, the lifting assembly 3a works. The hollow rotating platform 3bb connected to the telescopic rod is lifted by the telescopic rod of the lifting cylinder 3aa. At this time, because the hollow rotating platform 3bb is fixedly connected to the suction cup mounting plate 3bc and the lifting support plate 3ba, the suction cup mounting plate 3bc, the hollow rotating platform 3bb, the lifting support plate 3ba, and the electromagnetic suction cup 3bd all move upward. When the electromagnetic suction cup 3bd touches the bottom of the tooling, it firmly sucks the tooling. And the tooling is lifted up and away from the roller of the conveying device 1. Then the hollow rotating platform 3bb works to drive the suction cup mounting plate 3bc to rotate, thereby driving the casting to rotate. At this time, the X-ray generator 2d on the flaw detection device 2 and the flat panel detector 2e, combined with the external detection control device, detect the casting. After the detection is completed, the telescopic rod of the lifting cylinder 3aa falls back, and the tooling with the casting on it falls onto the conveying device 1 and continues to flow backward, thus completing the entire flaw detection process.
