DETAILED DESCRIPTION

[0018] Please refer to Figures 1-4 The utility model provides the following technical scheme: including bearing base 1, bearing base 1 top fixedly connected with constraint ring 11, bearing base 1 top slidingly connected with several starting positioning blocks 2, several starting positioning blocks 2 are distributed in circle symmetry, several starting positioning blocks 2 top all are fixedly connected with extension block 21, several extension blocks 21 all are slidingly connected with judging rod 3 in inside, several judging rods 3 one side all are fixedly connected with contact block 31, bearing base 1 top is fixedly connected with guide rod 41, and correction square ring 4 is slidingly connected in guide rod 41 outside.

[0019] In the embodiment: the bearing base 1 is used to support and connect various parts, so as to complete the detection of the concentricity of the pipe mold through the cooperation of other parts. When detecting, the worker can place the pipe mold above the bearing base 1, and place the outer ring of the pipe mold inside the constraint ring 11. The constraint ring 11 can position the position of the outer ring of the pipe mold, avoid the deviation of the position of the outer ring of the pipe mold, and ensure the accuracy of the subsequent detection. Then the worker can slide the starting positioning block 2 until the several starting positioning blocks 2 contact the outer ring of the pipe mold. The starting positioning block 2 will drive the judging rod 3 to move synchronously through the extension block 21 when moving. One side of the judging rod 3 is fixedly connected with the contact block 31. When the several starting positioning blocks 2 contact the outer ring of the pipe mold, and the sliding distance of the several judging rods 3 in the starting positioning block 2 is the same, the several contact blocks 31 are concentric with the several starting positioning blocks 2. Therefore, the worker can slide the several judging rods 3 to make the several contact blocks 31 contact the pipe column of the pipe mold. Then the worker can quickly judge the concentricity of the pipe mold by observing whether the several judging rods 3 slide the same distance in the starting positioning block 2. When the concentricity of the pipe mold deviates, the worker can press down the correction square ring 4. The correction square ring 4 will move through the guidance of the guide rod 41 when sliding, so as to ensure that the correction square ring 4 will not deviate when moving. The correction square ring 4 will contact the judging rod 3 when moving downward. When the sliding distance of the several judging rods 3 in the starting positioning block 2 is different, that is, the concentricity of the pipe mold deviates, the correction square ring 4 cannot contact the several judging rods 3 at the same time. During the process of continuously sliding downward, the correction square ring 4 drives the judging rod 3 which contacts first to move, so that the judging rod 3 drives the contact block 31 and the pipe column of the pipe mold to move synchronously until the sliding distance of the several judging rods 3 in the starting positioning block 2 is the same. As known from the above, when the sliding distance of the several judging rods 3 in the starting positioning block 2 is the same, the pipe column of the pipe mold contacted by the several contact blocks 31 is concentric with the outer ring of the pipe mold contacted by the several starting positioning blocks 2. At this time, the correction square ring 4 contacts all the judging rods 3 at the same time, and the correction square ring 4 cannot continue to move downward, that is, cannot continue to drive the judging rod 3, the contact block 31 and the pipe column of the pipe mold to move. Then the worker can connect and fix the outer ring of the pipe mold and the pipe column of the pipe mold, and then complete the correction of the concentricity of the pipe column of the pipe mold. Through the downward pressing of the correction square ring 4 to correct the concentricity of the pipe column of the pipe mold, the worker does not need to manually adjust the movement of the pipe column of the pipe mold, so as to improve the operation efficiency of the worker. The correction square ring 4 and the judging rod 3 cooperate to ensure the correction accuracy of the concentricity of the pipe mold, so as to finally achieve the purpose of being convenient for the worker to operate.
