Adopt said structure, in use, expansion sleeve is stretched in end cylinder, chuck is against on end cylinder end face, turn bolt, plug is moved towards near the direction of chuck, by the conical surface that plug coordinates with expansion sleeve, expansion sleeve is outwards expanded, and extrude end cylinder inwall, until and compress between end cylinder inwall, so just by expansion gear together with end cylinder compact siro spinning technology, then chuck is coordinated by the processing tool of latch with end cylinder, end cylinder firmly can be fixed, prevent it from adding rotation in man-hour, this expansion mechanism easy installation and removal, and end cylinder can not be damaged, clamping efficiency is high.
As preferably: described chuck hub offers shoulder hole, and the first surface of chuck is connected with expansion sleeve, and second of chuck has been uniformly distributed circumferentially latch.The latch of circumference coordinates with the latch of end cylinder processing tool, is convenient to fix.
As preferably: the first end of described expansion sleeve is connected with chuck, and expansion sleeve inwall is the conical surface reduced gradually from the second end to first end, and described expansion sleeve first end is the face of cylinder near the inwall of chuck.
As preferably: the aperture of described shoulder hole is rectangular opening, and described plug miner diameter end is connected with square projection, and this projection offers screwed hole vertically, and this projection stretches in the aperture in shoulder hole, described bolt is connected with screwed hole through shoulder hole.This projection coordinates with aperture, prevents plug from rotating when bolt turns.
As preferably: described plug is cylinder near one end of chuck, and this cylinder coordinates with the face of cylinder of described expansion sleeve inwall.
As preferably: the second end outer wall of described expansion sleeve is provided with a circle boss, thickness increases, and prevents from interfering, and be convenient to compress, the external diameter of expansion sleeve first end is less than the second end and prevents first end outer wall and the end cylinder inwall from interfering.
As preferably: be provided with pad in the macropore of described shoulder hole, described bolt is pressed on this pad.
As preferably: described dilatation joint is 4 to 8.
As preferably: described expansion sleeve and chuck one-body molded, the axiality of expansion sleeve and chuck is easier to ensure, structure is more firm, and clamping is more reliable.
As mentioned above, the beneficial effects of the utility model are: can realize clamping fast with end cylinder and dismantling, then chuck is coordinated by the processing tool of latch with end cylinder, end cylinder firmly can be fixed, prevent it from adding rotation in man-hour, this expansion mechanism easy installation and removal, and end cylinder can not be damaged, clamping efficiency is high.

Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar the content disclosed by this description can understand other advantages of the present utility model and effect easily.
As shown in Figures 1 to 5, the utility model provides a kind of expansion clamping device, the chuck 2 comprising expansion sleeve 1 and be connected with expansion sleeve 1 one end, expansion sleeve 1 offers many dilatation joints 11 vertically, in this expansion sleeve 1, plug 3 is installed, this plug 3 side is taper, the inwall of expansion sleeve 1 is the conical surface adapted with plug 3, the miner diameter end of this plug 3 is towards chuck 2, bolt 4 is threaded with the miner diameter end of plug 3 through chuck 2, strain between plug 3 and expansion sleeve 1, chuck 2 center offers shoulder hole 22, the first surface of chuck 2 is connected with expansion sleeve 1, second of chuck 2 has been uniformly distributed circumferentially latch 21, the latch 21 of circumference coordinates with the latch 21 of end cylinder 6 processing tool, be convenient to fix.
The first end of expansion sleeve 1 is connected with chuck 2, expansion sleeve 1 inwall is the conical surface reduced gradually from the second end to first end, expansion sleeve 1 first end is the face of cylinder near the inwall of chuck 2, plug 3 is cylinder near one end of chuck 2, this cylinder coordinates with the face of cylinder of expansion sleeve 1 inwall, the aperture of shoulder hole 22 is rectangular opening, plug 3 miner diameter end is connected with square projection 31, this projection 31 offers screwed hole 32 vertically, this projection 31 stretches in the aperture in shoulder hole 22, bolt 4 is connected with screwed hole 32 through shoulder hole 22, pad 5 is provided with in the macropore of shoulder hole 22, bolt 4 is pressed on this pad 5.This projection 31 coordinates with aperture, prevents plug 3 from rotating when bolt 4 turns.
