Description

Technical Field

[0001] This utility model relates to the field of stamping part detection technology, specifically an automatic detection device for microcracks in stamping parts. Background Technology

[0002] Stamping is a process in which external force is applied to sheet metal, strip, tube, and profile through a press and dies to cause plastic deformation or separation, thereby obtaining workpieces of the required shape and size. After production, stampings need to be inspected for microcracks. Under current technology, ultrasonic flaw detectors are used to conduct comprehensive inspections of stampings, which can detect internal cracks and defects.

[0003] However, in actual operation, the inventors found the following problems: In the process of using an ultrasonic flaw detector to detect microcracks in stamped parts, the stamped parts cannot be quickly positioned, which causes a certain error in the accuracy of the measured data, which in turn leads to a decrease in the accuracy of the measurement.

[0004] Based on this, the present invention provides an automatic detection device for microcracks in stamped parts. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an automatic detection device for microcracks in stamped parts, which has the advantage of quickly positioning and clamping stamped parts, thus solving the problems mentioned in the background technology.

[0006] This utility model provides the following technical solution: an automatic detection device for microcracks in stamped parts, comprising a first device housing, a rotating disk attached to the top of the first device housing, a third device housing fixedly connected to the top of the rotating disk, a limiting groove formed on the top of the third device housing, a sliding plate slidably connected inside the limiting groove, a clamping plate fixedly connected to the top of the sliding plate, a fixing plate fixedly connected to the top of the sliding plate, a damping rod and a spring fixedly installed on the side of the fixing plate, an mounting plate fixedly connected to the side of the damping rod and the spring, and the third device housing fixedly connected to the top of the mounting plate.

[0007] Preferably, a control switch is provided on the outer side of the device housing, the control switch is connected to a drive motor via a circuit, a gear is fixedly connected to the output end of the drive motor, a gear is meshed inside the tooth groove of the gear, a connecting shaft is fixedly connected inside the gear, and a rotating disk is fixedly connected to the top of the connecting shaft.

[0008] Preferably, the fixing plate has two sets of mounting holes, and the interior of both sets of mounting holes is fitted with a limiting guide rail. One side of the limiting guide rail is fixedly connected to the inner wall of the equipment housing, and the other side of the limiting guide rail is fixedly connected to one side of the mounting plate.

[0009] Preferably, a second device housing is fixedly connected to the top of the first device housing, and a sliding groove is provided on the outer arc surface of the second device housing. A slider is slidably connected inside the sliding groove, and a side plate is fixedly connected to the outside of the slider.

[0010] Preferably, a detection probe is fixedly installed on the top of the second equipment housing, and an ultrasonic flaw detector is connected to the top of the detection probe.

[0011] Preferably, a drive motor is fixedly installed at the bottom end of one cavity of the device housing.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This automatic microcrack detection device for stamped parts uses a slider fixedly installed on the inner side of the side plate to slide within a groove in the second equipment housing. This allows the side plate to slide against the surface of the second equipment housing, opening a window on the surface of the second equipment housing. The stamped part to be inspected for microcracks is then placed on top of the third equipment housing. The stamped part itself exerts an outward pushing force on the two sets of clamping plates. Under this force, the two sets of sliding plates at the bottom of the two sets of clamping plates move outward within the limiting groove. Simultaneously, the damping rods and springs on the side of the fixed plate, which are fixedly connected to the bottom of the two sets of sliding plates, generate elastic tension on the side of the mounting plate. At the same time, the limiting guide rail inside the fixed plate provides a limiting effect. The elastic potential energy of the damping rods and springs achieves automatic clamping and positioning. The stamped part is then inspected for microcracks using a detection probe at the bottom of an ultrasonic flaw detector. Throughout the entire operation, the stamped part is kept below the detection probe, ensuring the accuracy of the detection data. Attached Figure Description

A housing 3 9 is fixedly connected to the top of the rotating disk 8. A limiting groove 11 is formed on the top of the housing 3 9. A sliding plate 12 is slidably connected inside the limiting groove 11. A clamping plate 10 is fixedly connected to the top of the sliding plate 12. A fixing plate 13 is fixedly connected to the top of the sliding plate 12. A damping rod 15 and a spring 16 are fixedly installed on the side of the fixing plate 13. A mounting plate 17 is fixedly connected to the side of the damping rod 15 and the spring 16. The housing 3 9 is fixedly connected to the top of the mounting plate 17. By sliding a slider fixedly installed inside the side plate 4 within a groove 3 formed in the housing 2, the side plate 4 can be controlled to slide against the surface of the housing 2, thereby controlling the sliding of the housing 2. Open the window on surface 2, and place the stamped part to be inspected for microcracks on top of the equipment housing 39. The stamped part itself generates an outward pushing force on the two sets of clamping plates 10. Under the action of the force, the two sets of sliding plates 12 at the bottom of the two sets of clamping plates 10 move outward inside the limiting groove 11. At the same time, the damping rod 15 and spring 16 on the side of the fixed plate 13 fixedly connected to the bottom of the two sets of sliding plates 12 generate elastic tension on the side of the mounting plate 17. Meanwhile, the limiting guide rail 14 inside the fixed plate 13 forms a limiting effect. Then, the elastic potential energy of the damping rod 15 and spring 16 is used to achieve automatic clamping and positioning. Then, the detection probe 7 at the bottom of the ultrasonic flaw detector 6 is used to inspect the stamped part for microcracks. During the entire operation, the stamped part is kept below the detection probe 7 to ensure the accuracy of the detection data.

[0021] The outer side of the equipment housing 1 is equipped with a control switch 5, which is connected to a drive motor 18 via a circuit. The output end of the drive motor 18 is fixedly connected to a gear 19, and a gear 20 meshes inside the tooth groove of the gear 19. A connecting shaft 21 is fixedly connected inside the gear 20, and a rotating disk 8 is fixedly connected to the top of the connecting shaft 21. The start and stop control switch 5 controls the drive motor 18 to switch on and off. The gear 19 fixedly connected to the output end of the drive motor 18 controls the rotation of the connecting shaft 21 fixedly connected inside the meshing gear 20. During the rotation, the rotating disk 8 fixedly connected to the top of the connecting shaft 21 drives the equipment housing 9 fixedly connected to rotate, thereby driving the stamped parts to rotate. This allows for detection at different angles, making the detection of microcracks more comprehensive.

[0022] The fixing plate 13 has two sets of mounting holes, and the interior of the two sets of mounting holes is fitted with a limiting guide rail 14. One side of the limiting guide rail 14 is fixedly connected to the inner wall of the equipment housing 9, and the other side of the limiting guide rail 14 is fixedly connected to one side of the mounting plate 17.

[0026] Working principle: The slider fixedly installed on the inner side of the side plate 4 slides inside the groove 3 opened in the equipment housing 2, thereby controlling the side plate 4 to slide against the surface of the equipment housing 2, opening the window on the surface of the equipment housing 2. Then, the stamped part to be inspected for microcracks is placed on top of the equipment housing 9. The stamped part itself generates an outward pushing force on the two sets of clamping plates 10. Under the action of the force, the two sets of sliding plates 12 at the bottom of the two sets of clamping plates 10 move outward inside the limiting groove 11. At the same time, the damping rod 15 and spring 16 on the side of the fixed plate 13 fixedly connected to the bottom of the two sets of sliding plates 12 generate elastic tension on the side of the mounting plate 17. The internal limiting guide rail 14 of the 13 forms a limiting function, and then the elastic potential energy of the damping rod 15 and the spring 16 is used to achieve automatic clamping and positioning. Then, the detection probe 7 at the bottom of the ultrasonic flaw detector 6 is used to detect microcracks in the stamped part. The start and stop control switch 5 is used to control the drive motor 18 to switch on and off. The gear 19 fixedly connected to the output end of the drive motor 18 controls the meshing gear 20 to rotate the connecting shaft 21 fixedly connected inside.
