Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic flaw detection equipment, in particular to a quality inspection device for aluminum-magnesium alloy die castings. Background Art

[0002] Ultrasonic flaw detection is an advanced method for inspecting defects in parts. It mainly uses the characteristic that ultrasound can penetrate deep into metal materials. When it passes through a section and enters another section, the reflection at the edge of the interface is used to determine whether there are defects. However, the ultrasonic wave interacts with the material of the test piece and the defects in it, causing its propagation direction or characteristics to change. The changed ultrasonic wave is received by the detection device and can be processed and analyzed. According to the characteristics of the received ultrasonic wave, the existence and defect characteristics of the test piece itself and its internal defects are evaluated.

[0003] Ultrasonic flaw detection is widely used in the field of parts flaw detection. Existing ultrasonic flaw detectors can only detect single parts during detection, that is, the operator puts the part in the instrument and takes it out manually after the detection. This is not suitable for the detection of a large number of parts. To this end, we propose a quality inspection device for aluminum-magnesium alloy die castings. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figures 1 to 7 , the utility model provides a technical solution: a quality inspection device for aluminum-magnesium alloy die castings, comprising two parallel support beams 1, and bottom support legs 4 at both ends of the support beam 1;

[0033] A plurality of second support rollers 5 are arranged at intervals on the top of the support beam 1. Both ends of the second support rollers 5 are rotatably connected to the second bearing seats 10. The second bearing seats 10 are respectively installed on the top of the support beam 1. The second support rollers 5 are connected by a conveyor belt 9. The end of the second support roller 5 located at one end of the support beam 1 is connected to a drive motor 8. The bottom of the drive motor 8 is installed on a motor mounting plate 7. The motor mounting plate 7 is connected to the support beam 1. When the drive motor 8 rotates, the conveyor belt 9 can be driven to rotate. In actual use, the casting is placed at one end of the conveyor belt 9 and moves forward as the conveyor belt 9 rotates.

[0034] like Figure 1 As shown, two support beams 1 are provided with a support 24 at one side away from each other, and the support 24 is preferably arranged in the middle position of the side of the support beam 1, and both ends of the top of the support 24 are connected to a support frame 15 extending to the top of the conveyor belt 9, and the top of the support frame 15 is connected to the frame 16, and a connecting beam 17 is installed in the middle of the frame 16, and the connecting beam 17 is horizontally placed above the conveyor belt 9;

[0035] A first telescopic mechanism 19 is installed in the middle of the connecting beam 17. The first telescopic mechanism 19 is a cylinder, an electric telescopic rod or a hydraulic cylinder. A mounting shell 20 is installed at the bottom of the first telescopic mechanism 19. An ultrasonic probe (not shown in the figure) is arranged in the mounting shell 20. The ultrasonic probe is connected to the flaw detector through a wire.

[0036] Specifically, when the utility model is used, the castings are placed on the conveyor belt 9 in sequence, and the castings are locked to the conveyor belt 9 and rotated and gradually advanced forward. When the castings gradually pass under the mounting shell 20, they are irradiated by the ultrasonic probe, and then the irradiated image is transmitted to the flaw detector.

The top of the first guide shaft 18 is arranged through the connecting beam 17 to play a guiding and stabilizing role.

[0038] Further, such as Figure 3 As shown, the tops of the two support legs 4 at the ends of the support beam are connected by a reinforcing beam 27, so that the support beams are more stable; a strip seat 31 is provided below the reinforcing beam 27, and both ends of the strip seat 31 are connected to the support rail 29 through sliders, and the support rail 29 is installed on the side of the support leg 4; so that the strip seat 31 can move up and down along the support rail 29;

[0039] like Figure 3 As shown, a pressing roller 32 is provided below the bottom of the strip seat 31, and both ends of the pressing roller 32 are rotatably connected in the third bearing seat 28, and the third bearing seat 28 is installed below both ends of the strip seat 31;

[0040] An adjusting screw 30 is vertically installed at the middle position of the top of the strip seat 31, and third guide shafts 26 are vertically installed at both ends of the top of the strip seat 31. The third guide shaft 26 and the top of the adjusting screw 30 are both penetrated and arranged on the reinforcing beam 27. The adjusting screw 30 and the reinforcing beam 27 are fastened by nuts, so the adjusting screw 30 can be driven to move up and down by adjusting the tightness of the nut, thereby changing the height of the pressing roller 32. After adjustment, it can be fastened again by nuts.

[0041] For example Figure 3 As shown, first support rollers 2 are provided at both ends of the bottom of the two support beams 1 and near the support legs 4. Both ends of the first support rollers 2 are rotatably connected to the first bearing seats 3. The first bearing seats 3 are installed under the support beams 1.

Specifically, the push plate 14 stays in the push port 13 in the initial state, and the push port 13 and the surface of the baffle 12 are flush. When the casting moves forward with the conveyor belt and passes under the ultrasonic probe, the casting is ultrasonically scanned. If the casting is intact, the casting will move with the conveyor belt to the other end and fall. If the tested casting has defects such as damage, the second telescopic mechanism 22 will push the casting from the conveyor belt 9 to the push port 13 on the other side, and fall from the push port 13 under the continued push of the second telescopic mechanism 22, so as to realize the sorting of defective castings. After pushing is completed, the second telescopic mechanism 22 automatically returns to its initial position.

[0047] The controller is connected to the flaw detector, and the controller is connected to the operation screen 36. The operation screen 36 is arranged above the conveyor belt 9, and the operation screen 36 is arranged on the top of the mounting frame 37, so that the operator can operate the operation screen conveniently. The mounting frame 37 is installed on the top side of the support leg 4; the controller is also connected to the drive motor 8, the first telescopic mechanism 19, and the second telescopic mechanism 22 respectively. The controller can be a host, a PLC logic controller or an intelligent control circuit board. The control principle diagram of the controller is as follows: Figure 7 shown.

[0048] like Figure 4and Figure 5 As shown, the outer side of the support frame 15 and the top of the frame 16 are sealed by a sealing plate 33, and openings 34 are provided at positions of the sealing plate 33 corresponding to the conveyor belt 9 and the second material trough 25, and the openings 34 are used for the entry and exit of blanking and castings.

The first material trough 6 is inclined downward and the top is located below the conveyor belt 9 .

[0050] Finally, in order to more conveniently adjust the height of the ultrasonic probe, a distance detector may be installed at the bottom of the mounting shell 20 during actual use, such as Figure 4 As shown, a detector 38 is installed above the top of the opening 34 in the forward direction of the conveyor belt 9. The detector 38 and the distance detector are respectively connected to the controller. When a casting is detected passing by, the ultrasonic probe starts to work.
