Embodiment 1
[0039]Working Principle of Embodiment 1: Firstly, the end of the fixture provided with the expansion screw 2 is vertically placed in the inverted conical workpiece, and then the installation rod 9 is inserted from the bottom to the bottom of the lower expansion core 61 inside the lower expansion sleeve 62 , then turn the installation rod 9, and tighten it with the threaded hole 8 at the bottom, and then make the lower expansion core 61 move down, because the lower expansion core 61 is tapered, and the lower expansion sleeve 62 is set as a three-lobed toothed structure, and cooperates with the lower expansion core 61. The arc surface of the core 61 realizes expansion, and then the expansion screw 2 is turned, the expansion screw 2 matches the thread inside the upper expansion core 41, and the setting of the gasket 3 prevents the expansion screw 2 from being connected to the upper expansion sleeve The friction force of 42 is too large, as the expansion screw 2 is tightened, the e...
