It should be understood that the specific implementation manners described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.
[0022] Please refer to Figure 1 - Figure 2 , Figure 1 is the first three-dimensional structural schematic diagram of the detection device provided by the embodiment of the present utility model; Figure 2 is the second three-dimensional structural schematic diagram of the detection device provided by the embodiment of the present utility model. The magnetic detection device 1 for automotive parts of the present utility model includes a frame 11, a spraying assembly 12, a clamping assembly 13 and an electromagnet 14. The clamping assembly 13 is symmetrically arranged on the transverse two sides of the frame 11. The clamping assembly 13 includes a clamping base 131 and claws 132. The claws 132 are fixed on the clamping base 131 to clamp parts. The clamping base 131 is installed on the frame 11. The electromagnet 14 is installed on the clamping base 131 and is arranged in alignment with the claws 132 so that when the clamping assembly 13 clamps parts, the electromagnet 14 contacts the parts. When the electromagnet 14 is energized, it generates magnetism to change the magnetic field direction of the parts. The spraying assembly 12 is mounted on the frame 11 between the two groups of clamping assemblies 13 to spray magnetic suspension liquid on the parts.
[0023] When detecting defects in the drive shaft components of an automobile, first use the clamping assembly 13 to clamp and fix both ends of the component. Subsequently, energize the electromagnet 14 to change the magnetic field direction of the component. Then use the spraying assembly 12 to spray magnetic suspension fluid on the component, causing the magnetic suspension fluid to flow on the surface of the component. When there are cracks on the surface of the component or inclusions inside, the magnetic suspension fluid will accumulate at the defect location of the component. The operator can irradiate the surface of the component with ultraviolet light to quickly detect the accumulated magnetic suspension fluid, thereby determining the location of the defect in the component.
[0024] Compared with the existing component defect detection methods, the detection device 1 of the present utility model clamps both ends of the component through the clamping jaws 132, changes the magnetic field direction of the component through the electromagnet 14, and uses the spraying assembly 12 to spray magnetic suspension fluid on the component, so that the magnetic suspension fluid accumulates at the defect of the component. At this time, the operator can irradiate the surface of the component with an ultraviolet lamp to quickly detect the accumulated magnetic suspension fluid, thereby determining the location of the defect in the component, improving the efficiency and accuracy of defect detection. It can not only detect the fine defects on the surface of the component, but also detect the internal defects or inclusions of the component, avoiding potential safety hazards when the component is installed on the automobile.
[0025] In the embodiment of the present utility model, a slide rail 111 for two groups of clamping bases 131 to slide is provided on the frame 11. The two groups of clamping bases 131 slide along the slide rail 111 to adjust the distance between them, and further adjust the distance between the clamping jaws 132 on both sides, so that the clamping jaws 132 can clamp and fix components of different lengths, thereby realizing the defect detection of components of different lengths and improving the application range of the detection device 1.
[0026] In the embodiment of the present utility model, the clamping assembly 13 further includes a base driving member 133 fixed on the longitudinal sides of the frame 11. Both ends of the base driving member 133 are fixedly connected to the clamping bases 131 on the transverse sides of the frame 11 to drive the clamping bases 131 to slide along the slide rail 111. Among them, the base driving member 133 uses a cylinder, and when the cylinder expands and contracts, it drives the clamping bases 131 to slide along the slide rail 111, thereby realizing the adjustment of the distance between the clamping jaws 132 on both sides to adapt to components of different lengths and facilitating the defect detection of components of different lengths.
[0027] In the embodiment of the present utility model, the clamping jaw 132 includes any one of a three-jaw chuck, a four-jaw chuck, and a hydraulic chuck to drive the component to rotate, so that the operator can perform a comprehensive inspection on the circumferential surface of the component, improving the comprehensiveness and convenience of component defect detection.
[0028] In an embodiment of the present utility model, the spraying assembly 12 further includes a recovery box 121 located between two sets of clamping assemblies 13. The height of the recovery box 121 is lower than that of the clamping base 131. The frame 11 is provided with a through hole corresponding to the position of the recovery box 121, so that after the magnetic suspension liquid sprayed by the spraying assembly 12 flows down from the surface of the component, it flows into the recovery box 121 through the through hole, realizing the reuse of the magnetic suspension liquid and improving the environmental protection of the detection device 1.
[0029] In an embodiment of the present utility model, the spraying assembly 12 includes a spraying frame 122, a sliding seat 123 and a spraying pipe 124. The spraying frame 122 is fixed on the frame 11. The sliding seat 123 is slidably connected to the spraying frame 122 and can move horizontally along the spraying frame 122. The spraying pipe 124 is installed on the sliding seat 123, with one end pointing to the component and the other end inserted into the recovery box 121, so that the spraying pipe 124 extracts the magnetic suspension liquid from the recovery box 121. When spraying the component, the position of the spraying pipe 124 is adjusted by adjusting the position of the sliding seat 123 on the spraying frame 122, so that the spraying pipe 124 sprays different length positions of the component, facilitating the operator to perform ultraviolet irradiation on the positions sprayed with the magnetic suspension liquid, so as to quickly detect whether there are defects in the component, improve the detection efficiency. At the same time, the magnetic suspension liquid flowing down from the surface of the component flows back into the recovery box 121 through the through hole, realizing the reuse of the magnetic suspension liquid and improving the environmental protection of the detection device 1.
[0030] In an embodiment of the present utility model, a booster pump is arranged in the recovery box 121. One end of the spraying pipe 124 inserted into the recovery box 121 is connected to the booster pump, so as to extract the magnetic suspension liquid into the spraying pipe 124 under the action of the booster pump and make the spraying pipe 124 automatically spray the surface of the component, improving the spraying efficiency.
[0031] In an embodiment of the present utility model, the magnetic detection device 1 for automotive components further includes a controller 15 fixed on the frame 11. The controller 15 is electrically connected to the spraying assembly 12, the clamping assembly 13 and the electromagnet 14, so as to control the spraying assembly 12 to spray the magnetic suspension liquid, control the clamping assembly 13 to clamp the component, and control the electromagnet 14 to be energized, so that the operator can control the detection device 1 to perform automatic defect detection on the component through control, improving the intelligence of the detection device 1.
[0032] In an embodiment of the present utility model, the magnetic detection device 1 for automotive components further includes a detection camera and an ultraviolet searchlight installed on the sliding seat 123. Both the detection camera and the ultraviolet searchlight are electrically connected to the controller 15, so as to detect the defects of the component by the detection camera under the irradiation of the ultraviolet searchlight, further improving the automatic effect of the detection device 1 for detecting the defects of the component and improving the detection efficiency of the detection device 1.
[0033] In an embodiment of the present utility model, an audible and visual alarm 151 is further provided on the controller 15. When the inspection camera detects a defect in a component, the audible and visual alarm 151 is triggered to give an alarm, so that an operator can determine whether a component has a defect according to the alarm prompt, facilitating secondary processing of the defective component.
