DETAILED DESCRIPTION

[0023] The following description is used to disclose the utility model so that those skilled in the art can realize the utility model. The preferred embodiments in the following description are only as examples, and other obvious variants can be thought of by those skilled in the art.

[0024] Referring to Figures 1-4 As shown in the figure, a kind of metal product quality detection flaw detection mechanism, including flaw detection seat 1, movable support 3 is slidably arranged on the top opening of flaw detection seat 1 in inverted U shape and flaw detector 4 is installed on the inner wall of the top end of movable support 3;

[0025] The both sides of flaw detection seat 1 are transversely provided with electric guide rail 2, and electric sliding seat 5 fixedly connected with the end of movable support 3 is slidably arranged in the inner side of electric guide rail 2;

[0026] ​In use, the metal product to be detected is placed in the inside of the detection seat 1, and then the electric guide rail 2 is turned on, so that the electric sliding seat 5 slides in the inside, and then the movable support 3 slides on the top opening of the detection seat 1, so that the detector 4 passes through the product, effectively detecting the single side of the metal.

[0027] Further, referring to Figures 1-4 It is worth noting that it also includes two groups of flip type clamping mechanisms, which are respectively located on both sides of the detection seat 1.

[0028] The flip type clamping mechanism includes a new type of clamp seat in the shape of C slidingly arranged in the inside of the detection seat 1, a turning plate 8 arranged between the new type of clamp seat and the inside wall of the detection seat 1, and an extension component arranged between the turning plate 8 and the new type of clamp seat.

[0029] The new type of clamp seat is composed of two upper and lower symmetrical adhesion plates 7 and a support 6 vertically arranged between the two adhesion plates 7, and the bottom surface of the uppermost adhesion plate 7 is provided with a movable slot, and the movable slot is provided with an extrusion assembly.

[0030] The extension component includes a first electric push rod 9 mounted between the turning plate 8 and the support 6, and the two sides of the first electric push rod 9 are respectively provided with extension guide rods 10, and the two ends of the extension guide rods 10 are respectively fixedly connected with the turning plate 8 and the support 6.

[0031] The extrusion assembly includes a pressing plate 21 slidingly arranged in the movable slot, and the top center of the uppermost adhesion plate 7 is provided with a push-pull screw 22, and the push-pull screw 22 is threadedly penetrated into the movable slot and rotationally connected with the pressing plate 21, and the two sides of the push-pull screw 22 are respectively provided with limiting rods 23, and the limiting rods 23 are penetrated into the movable slot and fixedly connected with the pressing plate 21.

[0032] Through the arrangement of the flip type clamping mechanism, after the metal product is placed in the inside of the detection seat 1, the first electric push rod 9 in the two groups of flip type clamping mechanisms is turned on, so that the extension end of the first electric push rod 9 extends and pushes the C-shaped new type of clamp seat composed of the two adhesion plates 7 and the support 6 to slide towards the metal product, until the C-shaped new type of clamp seat is clamped on the metal product.

[0033] Then the push-pull screw 22 in the knob extrusion assembly is rotated, so that the push-pull screw 22 continuously penetrates into the movable slot under the thread structure and pushes down the pressing plate 21 to slide down, until the pressing plate 21 is tightly attached to the surface of the metal product, so as to effectively realize the fixed clamping effect of the metal product, and ensure the stability of the metal product during the detection.

[0034] During the sliding of the C-shaped new type of clamp seat and the pressing plate 21, the extension guide rods 10 are synchronously extended and retracted with the first electric push rod 9, and the limiting rods 23 are synchronously penetrated into the movable slot with the pressing plate 21, so as to effectively limit the movement trajectory of the C-shaped new type of clamp seat and the pressing plate 21.

[0035] Further, referring to Figure 3 , it is worth mentioning that the flip type clamping mechanism also includes a motor 11 mounted on the outer wall of the flaw detection seat 1, and the output shaft of the motor 11 penetrates into the flaw detection seat 1 and is fixedly connected with the rotating plate 8.

[0036] Through the setting of the motor 11, after the single-side flaw detection of the metal product is completed by the flaw detector 4 through the sliding movable support 3, only the motor 11 needs to be simply turned on to make the output shaft of the motor 11 rotate by one hundred and eighty degrees, so that the new type of clamp seat can make the metal product rotate by one hundred and eighty degrees synchronously, and then the metal product can be changed in a short time without manual operation, thereby improving the work efficiency.

[0037] However, due to the setting of the C-shaped new type of clamp seat, the local surface of the metal product will be blocked by the matching plate 7 in the C-shaped new type of clamp seat after the metal product is clamped and held by the C-shaped clamp, which causes the surface of the metal product to be unable to be completely detected by the flaw detector 4, thereby affecting the flaw detection effect.

[0038] Therefore, referring to Figure 3 and Figure 4 , it is worth mentioning that the connecting part between the matching plate 7 and the support 6 is provided with a movable component;

[0039] The movable component includes a movable rotating rod 12 transversely arranged on the end of the support 6, two bearing seats 13 fixedly connected with the end of the support 6 are symmetrically arranged on the rod body of the movable rotating rod 12, and a connecting sleeve 14 located between the two bearing seats 13 is tightly sleeved on the rod body of the movable rotating rod 12, the connecting sleeve 14 is fixedly connected with the side wall of the matching plate 7, and a transmission assembly for acting on the rotation of the movable rotating rod 12 is arranged on the side wall of the support 6.

[0040] Through the setting of the movable component, when the electric guide rail 2 is turned on and the movable support 3 carries the flaw detector 4 to slide and detect the surface of the metal product, the transmission assembly corresponding to the upper matching plate 7 can act on the rotation of the movable rotating rod 12, so as to quickly flip the upper matching plate 7, so that the upper matching plate 7 is separated from the upper surface of the metal product, while the lower matching plate 7 continues to remain horizontal and assists in bearing the metal product. In this way, without affecting the stability of the metal product detection, the rotation of the upper matching plate 7 can avoid blocking the corresponding surface of the metal product and the flaw detector 4, so as to avoid affecting the flaw detection effect of the flaw detector 4.

[0041] Further, referring to Figure 4 , it is worth mentioning that the transmission assembly includes a pull rod 15 transversely arranged between the support 6 and the rotating plate 8, and a second electric push rod 18 mounted between the pull rod 15 and the support 6, both ends of the pull rod 15 are fixedly provided with a rack 16, and both ends of the movable rotating rod 12 are fixedly sleeved with a gear 17 engaged with the rack 16.

[0042] The inner wall of the middle part of the pull rod 15 is provided with an infrared sensor 20, and the inner side wall of the probe seat 1 is provided with an infrared generator 19 corresponding to the infrared sensor 20. The infrared sensor 20 is electrically connected with the second electric push rod 18, and the infrared generator 19 is electrically connected with the electric guide rail 2.

[0043] When the C-shaped clamping seat is turned by 180 degrees by starting the motor 11, the infrared sensor 20 on the pull rod 15 corresponding to the upper adhering plate 7 can be synchronously turned to a position corresponding to the infrared generator 19, and then the electric guide rail 2 is started, so that the movable support 3 carries the probe 4 to slide on the upper surface of the metal product. The infrared generator 19 is synchronously connected with the current and started, so that the infrared generator 19 generates infrared rays to the infrared sensor 20, the infrared sensor 20 receives the infrared rays and sends a signal to the second electric push rod 18, and then the second electric push rod 18 is started and pulls the pull rod 15 away from the rotating plate 8. In this process, the rack 16 synchronously displaces the pull rod 15, and continuously engages with the gear 17, so that the movable rotating rod 12 is forced to rotate and turn the upper adhering plate 7 upward, so that the adhering plate 7 is separated from the upper surface of the metal product.

[0044] In summary, through the cooperative design of the "inverted U-shaped movable support 3 + overturning clamping mechanism", the full-automatic operation of "fixing - detecting - changing surface - detecting again" in the batch detection process of metal products is realized, the efficiency bottleneck problem caused by manual overturning of the workpiece in the prior art is effectively solved, and the connection relationship and working process of each component are clear, which can be completely realized by the person skilled in the art according to the content of the specification.

[0045] In addition, referring to the related content of the prior art patent with the patent number CN218512364U and the name of a kind of electromagnetic ultrasonic pulse metal detection equipment, it is clear that the patent discloses the structure design of "U-shaped sliding frame and fixed frame across the workpiece seat, and the probe slides along the linear guide rail with the U-shaped frame". Its technical idea is to avoid interference with the workpiece by the layout of the U-shaped frame, and to drive the detection assembly to move by means of the guide rail. The structure design of the present application "inverted U-shaped movable support 3 + sliding detection" is completely identical, which proves that the "inverted U-shaped movable support 3 + sliding detection" is the prior art.

[0046] Meanwhile, the prior art also discloses adopting "electromagnetic ultrasonic pulse" as a flaw detection mechanism, and a use mode of "fixed workpiece + moving detection assembly" is highly adaptable to the structure of the application, and the open design of the inverted U-shaped movable support can naturally exclude radiation type flaw detection such as X / gamma ray which needs to be closed and protected, and is only suitable for non-radiation type flaw detection such as ultrasonic wave and electromagnetic ultrasonic wave, and in combination with the technical inspiration of the prior art, a person skilled in the art can directly and explicitly determine the flaw detection mechanism range of the flaw detector 4 of the application, and therefore the description about the flaw detection mechanism in the specification has met the clarity requirement, the flaw detector 4 is a conventional design consistent with the flaw detection mechanism adaptation logic in the prior art, and as the prior art, the application will not be described in more detail.
