DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0022] See also Figure 1-5 , a clamp for an ultrasonic phased array flaw detector, comprising a main body 1, a clamping adjustment mechanism, a rotation control mechanism and a lifting detection mechanism, the clamping adjustment mechanism comprising a clamping plate 2, a sliding frame 3, a slider 4, a first spring 5, a contact block 6 and an inner bolt 7, the clamping plate 2 is rotatably connected to the main body 1, the sliding frame 3 is mounted on the clamping plate 2 and is slidably connected to the clamping plate 2, the slider 4 slides inside the sliding frame 3, the first spring 5 is fixedly mounted inside the sliding frame 3 and is fixedly connected to the slider 4, the contact block 6 is detachably connected to the sliding frame 3 by bolts, the inner bolt 7 connects the contact block 6 and the sliding frame 3, the rotation control mechanism comprises a rotation connection mechanism and a positioning assembly, the rotation connection mechanism comprises a connecting column 8, a connecting plate 9 and a roller 10, the connecting column 8 is fixedly mounted on the bottom of the clamping plate 2, the connecting plate 9 is fixedly mounted on the connecting column 8, and the roller 10 is mounted inside the main body 1 and is slidably connected to the connecting plate 9.

[0023] When the workpiece is in the fixed position, the two adjusting rods 21 are slid in the second slot 20 on the sliding frame 3, thereby retracting the slider 4 and making the sliding frame 3 slide toward the outer periphery of the clamping plate 2, thereby completing the loosening and tightening of the workpiece.

[0024] In this embodiment, the rotation control mechanism includes a rotating connection mechanism and a locking assembly. The rotating connection mechanism includes a connecting column 8, a connecting disk 9 and a roller 10. The locking assembly includes a second spring 11, a locking column 12 and a push-pull handle 13. When in use, after the workpiece is fixed, the clamping disk 2 is rotated, the connecting column 8 rotates inside the main body 1, and the connecting disk 9 also rotates accordingly. Since the connecting disk 9 contacts the roller 10 inside the main body 1, the clamping disk 2 rotates very smoothly as a whole. When adjusting the position of the clamped workpiece, the push-pull handle 13 is pulled at this time to drive the locking column 12 to slide inside the third slide groove 22, so that the locking column 12 disengages from the second bayonet 23 on the connecting disk 9 and compresses the second spring 11. When the clamped workpiece is determined to be in the measured position, the push-pull handle 13 is released. The compressed second spring 11 bounces the locking column 12 into the second bayonet 23 of the connecting disk 9.

[0025] In this embodiment, the lifting detection mechanism includes a lifting frame 14, a placement block 15, a wire bundle tube 16 and a pipe support platform 17. When in use, first pass the connecting wire on the probe through the wire bundle tube 16 and insert it into the flaw detector. At this time, put the probe of the flaw detector into the large placement block 15, and slide it inside the lifting frame 14 to adjust the height. In conjunction with the above, rotating the clamping plate 2 can perform all-round detection of the workpiece. Example 2

[0026] When in use, first fix the workpiece, and directly push the sliding frame 3 to slide inside the first sliding groove 18 in the clamping plate 2. At this time, the sliding block 4 contacts the first bayonet 19. Due to the shape reason, after the sliding block 4 is squeezed and retracted into the sliding frame 3, it pops out of the sliding frame 3 and is installed in the bayonet. At the same time, the position of the contact block 6 installed on the sliding frame 3 and connected to the sliding frame 3 through the inner bolt 7 changes accordingly, and begins to clamp the component located at the center of the clamping plate 2, and gradually clamps it. In the process of the sliding frame 3 moving forward, the sliding block 4 continuously compresses the first spring 5. The state of the first spring 5 is always in the two states of compression and expansion until the sliding frame 3 is fixed in the position. When the workpiece is fixed, the clamping plate 2 is rotated at this time, the connecting column 8 rotates inside the main body 1, and the connecting plate 9 also rotates accordingly. Moreover, the connecting plate 9 is in contact with the roller 10 inside the main body 1, so that the clamping plate 2 rotates very smoothly as a whole. When adjusting the position of the clamped workpiece, this When the workpiece is fixed to the measuring position, the push-pull handle 13 is released, and the compressed second spring 11 is released to bounce the post 12 into the second slot 23 of the connecting disk 9, thereby completing the fixation of the rotating workpiece. Then, the detection is started. First, the connecting wire on the probe is passed through the wire harness tube 16 and inserted into the flaw detector. At this time, the probe of the flaw detector is placed in the large placement block 15 and slides inside the lifting frame 14 to adjust the height. In combination with the above, the clamping disk 2 can be rotated to perform a full-scale detection of the workpiece. After the detection is completed, the two adjusting rods 21 are slid in the second slot 20 on the sliding frame 3, thereby retracting the slider 4 into the sliding frame 3, and making the sliding frame 3 slide as a whole toward the periphery of the clamping disk 2, completing the loosening and tightening of the workpiece, and removing the workpiece.

[0027] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described one by one here. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
