Description

Technical Field

[0001] The utility model belongs to the technical field of metal material detection, in particular to a clamping and flipping component and a metal nondestructive detection flaw detection device. Background Art

[0002] Metal generally refers to a class of substances that have a unique luster, are opaque, ductile, and have thermal and electrical conductivity.

[0003] The prior art (publication number: CN216285254U) discloses a nondestructive testing device for metal materials, which relates to the technical field of metal material testing, and includes a support frame, a workbench body, an analyzer body and a detection probe, and a first clamping device is provided at the output end of the first motor.

[0004] The prior art uses bolt control to drive a clamp that can move up and down to cooperate with a clamp fixed below to clamp the workpiece and cooperate with a probe to perform flaw detection. Although the prior art can perform clamping and flaw detection, the clamp that clamps the workpiece in the prior art will block the clamped area of ​​the workpiece when clamping the workpiece, resulting in the probe being unable to perform flaw detection. The clamp must cancel the clamping of the blocked areas on both sides before flaw detection can be performed, but this process is more troublesome and may cause the workpiece to fall from the clamp. The prior art can also block the workpiece by rotating the wall clamp into a horizontal state when the clamp clamps the workpiece, but this method still has a great probability of causing the workpiece to slip and be damaged. Therefore, the prior art is more troublesome when performing flaw detection on the clamped workpiece.

[0005] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model.

The clamping structure is symmetrically arranged on the top of the base plate 20.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the tops of the clamping block 40, the fixed clamping plate 41 and the moving clamping plate 45 are in a U shape. The bottom plate 39 of the pocket is composed of a horizontal rectangular rod and a plurality of vertical rectangular rods fixedly connected to the front wall surface of the rectangular rod. The clamping structure further includes a linkage groove 31, a front groove 32, a spring groove 33, a linkage block 34 and a rotating shaft 35. The linkage groove 31 is opened at the top of the side frame 30. The front groove 32 is opened on the front wall surface of the side frame 30. The front groove 32 communicates with the linkage groove 31. The spring groove 33 is opened on the wall surface of the side frame 30 within the linkage groove 31. The linkage block 34 is rotatably connected to the wall surface of the side frame 30 within the linkage groove 31. The rotating shaft 35 is fixedly connected to the front wall surface of the linkage block 34. The rotating shaft 35 also rotates within the front groove 32. The rear wall surface of the clamping block 40 is fixedly connected to the front wall surface of the rotating shaft 35. The linkage groove 31 and the front groove 32 can form a convex-shaped groove. The rotating motor 22 can drive the linkage block 34. The linkage block 34 is an oval block. The rotating shaft 35 is cylindrical. The front groove 32 can adapt to the diameter of the rotating shaft 35. The clamping structure further includes a sliding plate 36, a spring block 37 and a passive rod 38. The sliding plate 36 is slidably connected to the lower half of the linkage groove 31. The spring blocks 37 are symmetrically and fixedly connected to the front and rear wall surfaces of the sliding plate 36. The passive rod 38 is fixedly connected to the top of the sliding plate 36.

[0033] During specific use, first, the bolt 46 is rotated through the nut to control the adjustment block 43 to slide in the adjustment slot 42 and drive the movable clamping plate 45 to slide at the same time. When the distance between the movable clamping plate 45 and the fixed clamping plate 41 is controlled to the maximum distance, the workpiece can be placed between the fixed clamping plate 41 and the movable clamping plate 45 and the bottom of the workpiece is in contact with the top of the bottom plate 39. At this time, the bolt 46 can be rotated through the nut to adjust the movable clamping plate 45 to clamp the workpiece between the movable clamping plate 45 and the fixed clamping plate 41 to fix the workpiece. After the workpiece is fixed, the probe can be used to detect flaws from the top of the workpiece. After the flaw detection on the top of the workpiece is completed, the power supply of the rotating motor 22 will be turned on, and the rotating motor 22 will drive the linkage block 34 to rotate one hundred and eighty degrees in the linkage slot 31. When the linkage block 34 rotates The rotating shaft 35, the clamping block 40, the fixed clamping plate 41, the adjusting groove 42, the adjusting block 43, the movable clamping plate 45, the bolt 46, the anti-skid pattern 47 and the clamped workpiece will be driven to rotate simultaneously. When the linkage block 34 rotates, the linkage block 34 will push the passive rod 38 downward, and the passive rod 38 will drive the slide plate 36, the spring block 37 and the bottom plate 39 to move a certain distance vertically downward and be pushed upward by the spring on the wall of the spring block 37 to return to their original positions after the rotation of the linkage block 34 is completed. At this time, the bottom plate 39 will still be in contact with the bottom of the workpiece, and the original bottom of the workpiece has been turned over. At this time, the probe can perform flaw detection on the top of the workpiece. After the flaw detection of the workpiece is completed, the wall nut of the bolt 46 is rotated to expand the distance between the movable clamping plate 45 and the fixed clamping plate 41, and the workpiece can be removed;

[0034] In summary, by setting up a clamping structure, the top of the workpiece can be completely exposed for probe inspection when the workpiece is inspected. Because the clamping structure can fix and clamp the two sides of the workpiece and cooperate with the bottom plate 39 to always support the bottom of the workpiece so that the upper wall of the workpiece can be fully exposed, compared with the existing technology, this solution is more convenient and faster when inspecting the workpiece.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, one end of the bolt 46 is rotatably connected to the wall surface of the clamp block 40 in the adjustment groove 42, and the other end of the bolt 46 penetrates from the side wall surface of the clamp block 40 and is fixedly connected with a nut. The bolt 46 can pass through the screw hole 44, and the outer wall surface of the bolt 46 is also connected to the inner thread of the screw hole 44. The anti-slip pattern 47 is in a twill shape, and the side wall surface of the movable clamp plate 45 facing the fixed clamp plate 41 is also fixedly connected with the anti-slip pattern 47. The symmetrical clamp block 40, the fixed clamp plate 41 and the movable clamp plate 45 in the symmetrical clamping structure at the top of the base plate 20 are symmetrical. The U-shaped openings formed by the symmetrical clamp block 40, the fixed clamp plate 41 and the movable clamp plate 45 face each other.

[0036] In actual use, when the fixed clamping plate 41 and the movable clamping plate 45 clamp the two sides of the workpiece, the anti-slip grooves 47 will contact and clamp the two sides of the workpiece;

[0037] To sum up, by providing the anti-slip pattern 47, the workpiece can be prevented from moving when the fixed clamping plate 41 and the movable clamping plate 45 clamp the workpiece, because the diagonal pattern of the anti-slip pattern 47 can reduce the downward inertia brought by the workpiece, thereby preventing the workpiece from moving and falling, and the bottom plate 39 can also always support the bottom of the workpiece to prevent it from falling, further improving the clamping stability of the device.

[0038] A metal nondestructive testing device, not shown in the figure, is a prior art of the same structure as in Publication No. CN216285254U, including a support frame, a workbench body, an analyzer body, a detection probe and an electromagnetic track, the support frame is placed on the ground, the workbench body is fixedly connected to the top of the support frame, the detection probe is installed below the analyzer body, the analyzer body is slidably connected to the electromagnetic track, the electromagnetic track is installed above the support frame, all the above-mentioned clamping and flipping components, a substrate 20 is installed on the top of the workbench body, and the bottom of the detection probe is vertically aligned with the top of the substrate 20;

[0039] In specific use, the substrate 20 is installed on the top of the workbench body through the threaded holes opened on its wall surface. After the clamping and flipping assembly clamps the workpiece, the analyzer body moves along the electromagnetic track, thereby driving the detection probe to perform flaw detection along the top of the workpiece;

[0040] In summary, by setting up a clamping and flipping assembly, the flaw detection speed of the device can be increased, its work efficiency can be improved, the working time can be reduced, and the workpiece can be prevented from falling during detection, which causes increased costs.

[0041] Working principle: First, the bolt 46 is rotated through the nut to control the adjustment block 43 to slide in the adjustment slot 42 and drive the movable clamping plate 45 to slide at the same time. When the distance between the movable clamping plate 45 and the fixed clamping plate 41 is controlled to the maximum distance, the workpiece can be placed between the fixed clamping plate 41 and the movable clamping plate 45 and the bottom of the workpiece is in contact with the top of the bottom plate 39. At this time, the bolt 46 can be rotated through the nut to adjust the movable clamping plate 45 to clamp the workpiece between the movable clamping plate 45 and the fixed clamping plate 41 to fix the workpiece. After the workpiece is fixed, the probe can be used to detect flaws from the top of the workpiece. After the flaw detection on the top of the workpiece is completed, the power of the rotating motor 22 will be turned on, and the rotating motor 22 will drive the linkage block 34 to rotate 180 degrees in the linkage slot 31. The linkage block 34 will rotate when it rotates. The rotating shaft 35, the clamping block 40, the fixed clamping plate 41, the adjustment groove 42, the adjustment block 43, the movable clamping plate 45, the bolt 46, the anti-slip groove 47 and the clamped workpiece are driven to rotate at the same time. When the linkage block 34 rotates, the linkage block 34 will push the passive rod 38 downward, and the passive rod 38 will drive the slide plate 36, the spring block 37 and the bottom plate 39 to move vertically downward for a distance and be pushed upward back to their original positions by the spring on the wall of the spring block 37 after the rotation of the linkage block 34 is completed. At this time, the bottom plate 39 will still be in contact with the bottom of the workpiece, and the original bottom of the workpiece has been flipped upward. At this time, the probe can perform flaw detection on the top of the workpiece. After the flaw detection of the workpiece is completed, the wall nut of the bolt 46 is rotated to expand the distance between the movable clamping plate 45 and the fixed clamping plate 41 and the workpiece can be removed.
