DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] like Figure 1-5As shown, an embodiment of the utility model discloses an aluminum alloy die-casting flaw detection device, comprising a lead room 2 for flaw detection of aluminum alloy die-castings and a conveyor belt 1 for conveying aluminum alloy die-castings, the conveyor belt 1 runs through the lead room 2; the conveyor belt 1 is tensioned on two transmission rollers 10, and the two ends of the transmission rollers 10 are hinged on two corresponding bearing seats 11; a plurality of clamping mechanisms 3 are arranged on the conveyor belt 1 at equal intervals.

[0028] Through the above arrangement, this embodiment can realize that several clamping mechanisms clamp and fix the aluminum alloy die-castings and place them equidistantly on the conveyor belt. The conveyor belt conveys the first clamping mechanism to the lead room for flaw detection. At this time, the conveyor belt stops conveying. After the X-ray flaw detector in the lead room completes the flaw detection of the aluminum alloy die-castings, the conveyor belt is started again to convey the clamping mechanism that has completed the flaw detection out of the lead room and at the same time convey the next clamping mechanism to the lead room for flaw detection. Repeat the above operation to realize continuous automatic flaw detection of aluminum alloy die-castings. It should be noted that the spacing between two adjacent clamping mechanisms on the conveyor belt can be determined according to the specific situation. As long as one clamping mechanism is conveyed to the designated flaw detection position in the lead room, the conveyor belt stops running. At this time, the adjacent clamping mechanisms on both sides of the clamping mechanism are located outside the lead room.

[0029] The clamping mechanism 3 includes two symmetrical clamping and fixing components for clamping and fixing the aluminum alloy die casting and two symmetrically arranged rotating components for rotating one of the clamping and fixing components respectively;

[0030] In this embodiment, the aluminum alloy die-casting is clamped and fixed by a clamping and fixing component, and the fixing component that has clamped and fixed the aluminum alloy die-casting is driven to rotate by a rotating component, so that a comprehensive flaw detection can be performed on different angles and surfaces of the aluminum alloy die-casting by an X-ray flaw detector, thereby improving the accuracy of flaw detection.

[0031] The two clamping and fixing assemblies each include a first electric push rod 30, a fixed rod 31 and a rotating rod 32. The fixed rod 3 is fixedly connected to the electric push rod 30, and the rotating rod 32 is hinged to the fixed rod 30. The electric push rod 30 is fixed on the U-shaped block 33. One side of the rotating rod 32 is provided with an arc-shaped clamping portion 320 that matches the outer wall of the aluminum alloy die casting.

[0032] The above arrangement of this embodiment can realize placing the aluminum alloy die-casting to be inspected on the horizontal bottom surface of the U-shaped block, and making the aluminum alloy die-casting to be inspected between the two fixed components, and then starting the two first electric push rods at the same time, so that the movable ends of the two first electric push rods move toward each other, so that the two fixed components move toward each other and enclose the aluminum alloy die-casting to be inspected, until the clamping parts of the four rotating rods are in contact with the outer surface of the aluminum alloy die-casting to be inspected, and then stop the operation of the two first electric push rods. At this time, the clamping parts of the four rotating rods clamp and fix the aluminum alloy die-casting to be inspected.

[0033] In this embodiment, a telescopic rod 310 is connected to the fixed rod 31, and the telescopic rod 310 includes a sleeve rod 311, a sliding rod 312 and an elastic member 313. The sleeve rod 311 is slidably connected to the sliding rod 312. The elastic member 313 is arranged inside the sleeve rod 311 and fixedly connected to the sleeve rod 311 and the sliding rod 312. The end of the sliding rod 312 away from the elastic member 313 is hinged to the rotating rod 32, and the end of the sleeve rod 311 away from the sliding rod 312 is hinged to the fixed rod 31.

[0034] The above arrangement of this embodiment can realize that by manually rotating the rotating rod, the two fixing components can be conveniently used to clamp and fix aluminum alloy die-castings of different sizes by changing the angle between the fixing rod and the rotating rod.

[0035] In this embodiment, the two rotating components each include a rotating shaft 40, a first support plate 41 and a rotating motor 42. One end of the rotating shaft 40 passes through a side surface of the U-shaped block 33 and is fixedly connected to the first electric push rod 30. The other end of the rotating shaft 40 is fixedly connected to a first spur gear 43. The first support plate 41 is fixedly connected to an outer wall of a side surface of the U-shaped block 33. The rotating motor 42 is fixedly arranged on the first support plate 41. A second spur gear 44 is fixedly connected to the output shaft of the rotating motor 42. The first spur gear 43 meshes with the second spur gear 44.

[0036] Through the above arrangement, the present embodiment can realize that by starting the rotating motor, the power output shaft of the rotating motor rotates to drive the second spur gear to rotate. Since the first spur gear is meshed with the second spur gear, the rotation of the second spur gear drives the first spur gear to rotate. The rotation of the first spur gear causes the rotating shaft to rotate. Since the rotating shaft is fixedly connected to the first electric push rod, the rotation of the rotating shaft drives the aluminum alloy die-casting clamped by the fixed assembly to rotate, thereby realizing the flipping of the aluminum alloy die-casting to be inspected, and then the aluminum alloy die-casting is comprehensively inspected at different angles and on various surfaces by an X-ray flaw detector, thereby improving the accuracy of flaw detection.

[0037] The bottom surface of the upper belt body of the conveyor belt 1 is fitted with a plurality of support mechanisms for supporting the bottom surface of the upper belt body of the conveyor belt 1. The plurality of support mechanisms each include a transmission support roller 50, both ends of which are hinged on two connecting seats 51 through bearings, the two connecting seats 51 are fixed on the top of the corresponding base 52, and the transmission support roller 50 is pressed against the bottom surface of the upper belt body of the conveyor belt 1.

[0038] In this embodiment, the utility model sets a plurality of transmission support rollers on the bottom surface of the upper belt body of the conveyor belt, and supports the bottom surface of the upper belt body of the conveyor belt through the transmission support rollers to ensure the supporting force during transportation, thereby reducing the possibility of deformation of the conveyor belt due to the gravity of the conveyor belt itself and the gravity of the materials being transported after long-term use of the conveyor belt, thereby improving the conveying effect of the conveyor belt.

[0039] In this embodiment, a plurality of bases 52 are fixedly disposed on the top of the second support plate 53 , and the second support plate 53 passes between the upper bag body and the lower bag body of the conveyor belt 1 .

[0040] The above arrangement in this embodiment can facilitate fixing of a plurality of bases on the second supporting plate.

[0041] In this embodiment, support beams 54 are provided on both sides of the second support plate 53 along the width direction of the conveyor belt 1, and two bearing seats 11 along the length direction of the conveyor belt 1 are fixedly connected to the top of the support beams 54 on the corresponding sides.

[0042] The above arrangement in this embodiment can facilitate the fixed installation of four bearing seats on the support beam.

[0043] In this embodiment, the bottoms of the two support beams 54 are fixedly connected with support legs 7 .

[0044] Through the above arrangement, this embodiment can support the support beam through the support legs.

[0045] In this embodiment, a fixed beam 20 is provided at the upper end of the interior of the lead room 2, and the two ends of the fixed beam 20 are respectively fixedly connected to the two inner walls of the lead room 2; a threaded rod 60 is horizontally fixedly provided at the bottom of the fixed beam 20, and one point of the threaded rod 60 is connected to the power output shaft of the drive motor 61, and the drive motor 61 is fixedly set at the bottom of the fixed beam 20, and a moving block 62 is threadedly connected to the threaded rod 60, and the moving block 62 is fixedly connected to the second electric push rod 63, and the movable end of the second electric push rod 63 is fixedly connected to the mounting plate 64, and the X-ray flaw detector 21 is fixed to the bottom of the mounting plate 64.

[0046] The above arrangement can be used to realize that by starting the driving motor, the power output shaft of the driving motor rotates forward or reversely to drive the threaded rod to rotate, and the rotation of the threaded rod drives the moving block to move left and right in the horizontal direction on the threaded rod. The moving block moves in the horizontal direction to drive the second electric push rod, the mounting plate and the X-ray flaw detector to move in the horizontal direction, thereby realizing the adjustment of the horizontal position of the X-ray flaw detector. At the same time, the second electric push rod can be started, and the movable end of the second electric push rod can be extended and retracted to drive the mounting plate and the X-ray flaw detector to move up and down in the vertical direction, thereby realizing the adjustment of the vertical position of the X-ray flaw detector. Further, comprehensive flaw detection of the aluminum alloy die-casting to be inspected is realized.

[0047] Finally, it should be noted that the above only describes in detail the specific embodiments of the utility model. However, the utility model is not limited to the specific embodiments described above. Equivalent modifications and substitutions made by technicians in this field to the utility model are also within the scope of the utility model.
