Description

Technical Field

[0001] This utility model relates to the field of mechanical processing and testing technology, and in particular to an integrated device for visual inspection of crankshaft after magnetic particle testing. Background Technology

[0002] The crankshaft is a critical component of an engine, and its quality directly affects the engine's performance and lifespan. Magnetic particle testing is a commonly used method in the field of nondestructive testing for inspecting surface and near-surface defects in ferromagnetic workpieces such as crankshafts.

[0003] During magnetic particle testing, magnetic suspension or dry magnetic powder is sprayed onto the workpiece surface to reveal defects. After testing, these residual magnetic particles (whether or not they form magnetic traces) must be thoroughly removed for subsequent defect verification and visual inspection.

[0004] In existing processing methods, the cleaning process for workpieces is usually separate and delayed. Operators need to remove the workpiece from the flaw detection work area before manually wiping or simply spraying it clean. This not only leads to residual magnetic powder (especially the magnetic suspension in wet flaw detection) easily obscuring minor defects, seriously interfering with the accuracy of subsequent visual inspection and defect confirmation, but also makes the entire cleaning process dependent on manual labor, inefficient, and unable to achieve automated continuous operation.

[0005] Furthermore, during manual cleaning or simple spraying processes, the wastewater containing magnetic powder is usually collected or discharged directly, lacking an effective, integrated, automatic recycling and filtration device. This not only wastes the magnetic powder but also increases the difficulty and cost of subsequent wastewater treatment.

[0006] Therefore, how to provide an integrated and automated device that can effectively remove residual magnetic powder from the workpiece surface after magnetic particle inspection to ensure inspection accuracy, while also automatically recovering the magnetic powder waste liquid, is a technical problem that urgently needs to be solved in this field.

[0007] Therefore, this utility model proposes an integrated device for visual inspection after magnetic particle testing of crankshafts to overcome the shortcomings of the prior art. Utility Model Content

[0032] As another preferred embodiment, please refer to Figure 4 The recycling component 8 also includes a handle 805, which is fixedly connected to the outer surface of the filter screen 804.

[0033] As another preferred embodiment, please refer to Figure 1 The device also includes a marker 9, which is fixed to the support frame 1 by an elastic cord.

[0034] The working principle of this utility model is as follows: The crankshaft workpiece is installed inside the base 3 fixed on the conveyor belt 2. The first motor 4 is started, which drives the conveyor belt 2 to rotate, thereby conveying the crankshaft workpiece. At the same time, the second motor 5 is started. The output end of the second motor 5 is fixedly connected to one end of the crankshaft workpiece, driving the crankshaft workpiece to rotate.

[0035] When the workpiece enters the area of ​​the pretreatment component 6, the electric push rod 603 is activated, pushing the mounting plate 602 toward the crankshaft workpiece. The guide rod 604 slides inside the first bracket 601, providing guidance and positioning for the mounting plate 602. At this time, the external water source connected by the connecting hose 606 sprays onto the rotating crankshaft workpiece through the nozzle 605 fixed on the front side of the mounting plate 602, rinsing the magnetic powder on the surface. The brush 607 installed at the bottom of the mounting plate 602 contacts the crankshaft workpiece as the mounting plate 602 moves. With the cooperation of the rotation of the crankshaft workpiece, the brush 607 dries the water stains on its surface and brushes away the remaining magnetic powder.

[0036] The pre-processed workpiece enters the area of ​​the second support 7 along the conveyor belt 2. The camera 11 installed inside the second support 7 takes pictures of the crankshaft workpiece, and the inspection results are displayed on the display screen 10 installed on one side of the second support 7. The employee observes the display screen 10 and operates the button 12 located below the display screen 10 to confirm the machine's judgment. After the workpiece flows out, the employee can perform a manual inspection and mark it with a marker pen 9 fixed to the support frame 1 by an elastic rope.

[0037] In the above process, the magnetic powder mixed with water falls into the collection box 801 located directly below the conveyor belt 2 through multiple holes on the surface of the conveyor belt 2. The wastewater collects in the collection hopper 802 fixedly connected to the bottom of the collection box 801, and then flows into the filter box 803 fixedly connected to the bottom outlet of the collection hopper 802. The wastewater is filtered inside the filter box 803 by the filter screen 804 that is slidably set inside. The solid magnetic powder is left on the surface of the filter screen 804, and the water is discharged. When it is necessary to recover the magnetic powder, the handle 805 fixedly connected to the outer surface of the filter screen 804 is pulled to slide the filter screen 804 out of the filter box 803.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
