Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bolt inspectors, in particular to a full-automatic bolt inspector. Background Art
[0002] Bolt inspection mainly involves the use of circular phased array probes to detect cracks in bolts, a detection technology widely used in modern industry. During the inspection process, a circular disc-type circular inspection is generally adopted. By inspecting the test piece rotating on the edge of the disc, the qualified and non-qualified test pieces are placed into different collection boxes. However, the traditional disc rotation structure has inconsistent clamping effects for test pieces of different sizes, making small-sized test pieces easy to loosen. During the rotation process, they are very likely to be thrown away by the centrifugal force generated by the rotation. This not only affects the work process, but also poses operational risks. Therefore, a fully automatic bolt inspection device is proposed. Utility Model Content

A chuck 8 is clamped between the fixing bolt 7 and the turntable 6. A chuck 8 is provided with a fixing bolt 7. During the adjustment of the fixed component, the card needs to be disassembled. At the same time, the chuck 8 is provided to protect the fixed component. A center cover 9 is provided in the middle of the upper end of the chuck 8. Hydraulics 10 are connected to both ends of the center cover 9. A center cover 9 is sleeved just above the bolt. A hydraulic servo system is installed in the center cover 9 to control the hydraulics 10 at the front and rear ends to perform telescopic movements. The hydraulic servo system enables the output of the system, such as displacement, speed or force, to automatically, quickly and accurately follow the changes in the input. At the same time, the output power is greatly amplified. A workpiece to be tested 11 is clamped between the chuck 8 and the upper end of the turntable 6. The loading port of the workpiece 11 to be tested is at the far left end and is transported by clamping the groove 1 and rotating the turntable 6. The detection box 3 is on the far right side of the tester and is tested facing the groove 1 on this side. Four fixing components are fixedly installed on the turntable 6.
[0029] See also Figure 4-5The fixing assembly includes a small shaft 12, which is fixed to the turntable 6 through the small shaft 12, and a fixing assembly is provided on the turntable 6 next to each piece to be tested 11, and a rotating block 13 is sleeved on the small shaft 12. A part of the rotating block 13 sleeved on the small shaft 12 is a disc structure, and the other part is a rod-shaped structure, and by manually turning the adjusting rod 16, the rod-shaped structure will rotate so as to be clamped and fixed with the piece to be tested 11, and the upper end of the rotating block 13 is rotatably connected to the large block 15, and the upper end of the small shaft 12 is rotatably connected to the small block 14, and the adjusting rod 16 is sleeved on the small shaft 12.

The plug-in part of the adjusting rod 16 and the small block 14 is provided with a disc structure, and an adjustment structure with an anti-slip groove is provided at its leftmost end. The function of the anti-slip groove is to facilitate its adjustment. The turntable 6 is rotated 180 degrees to face the detection box 3, and the workpiece 11 is detected. Then, the test result is used to determine whether to rotate 90 degrees to the left or 90 degrees to the right to transport it to different collection trays. The hydraulic machine 10 controlled by the hydraulic servo system above pushes the workpiece 11 to the qualified tray 4 or the unqualified tray 5 below to detect the workpiece 11. At the same time, the use condition of the fixed component is that the workpiece 11 to be tested is too small to be clamped on the groove 1, and the rotating block 13 can be rotated by rotating the adjusting rod 16 so that the rotating block 13 can clamp the workpiece 11 to be tested.
