Abstract
The utility model discloses a dismantling tool, its characterized in that: including screw rod, position sleeve, screw rod one end has the screw thread section, and the other end has the handle, it is protruding that position sleeve column cavity, one end have key shape, and the other end has the handle, the screw rod rotates the screw rod handle in packing the position sleeve into, and the screw rod can rotate in the position sleeve freely, the key of position sleeve shape is protruding insert the keyway of the main shaft pulling chuck of vertical machining center broach mechanism in, pass the hole of position sleeve to the screw rod, the screw rod handle rotates, screw rod screw thread section is screwed up in the screw thread of screw in chuck, the rotational positioning cover makes the hookup reliable completely of pulling chuck screw thread and main shaft broach pole, screw rod reverse rotation throws off with the pulling chuck, also throws off the position sleeve with the keyway of pulling chuck. The advantage is: guarantee reliably taut cutter of machining center main shaft, the location and the machining precision of cutter are intact, instrument operation with low costs, easy.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of dismantling device, relates in particular to a kind of machining center main spindle broach chuck disassembly tool, is specially adapted to the main spindle broach chuck dismounting of vertical machining centre tool-broaching mechanism.
Background technology
The main spindle broach chuck of vertical machining centre tool-broaching mechanism, through using after a while, wearing and tearing, when generation lathe falls cutter fault, need to change main spindle broach chuck; Main spindle broach chuck and main spindle broach bar are the spindle taper hole inside narrow and small at main shaft; When vertical machining centre main spindle broach chuck returns dress, and be main spindle broach chuck to be installed from lower to upper to main spindle broach bar, general utility tool is difficult to the reliable location of main spindle broach chuck to be connected and fixed; Specific purpose tool cost is high.
Summary of the invention
The utility model discloses a kind of dismantling device, when solving in prior art that vertical machining centre main spindle broach chuck returns dress, and be main spindle broach chuck to be installed from lower to upper to main spindle broach bar, general utility tool is difficult to the reliable location of main spindle broach chuck to be connected and fixed; Specific purpose tool high in cost of production problem.
The utility model comprises screw rod, positioning sleeve; Screw rod one end has thread segment, and the other end has handle; Positioning sleeve columnar hollow, one end has key shape projection, and the other end has handle; Screw rod packs in positioning sleeve, rotating screw bolt handle, and screw rod can freely rotate in positioning sleeve.
The key shape projection of positioning sleeve is inserted in the keyway of main spindle broach chuck of vertical machining centre tool-broaching mechanism, the endoporus screw rod through positioning sleeve, rotating screw bolt handle, screw flight section is tightened in the screw thread that screws in chuck; Rotation positioning sleeve, makes pulling chuck screw thread and the complete positive connection of main spindle broach bar; Screw rod reverse rotation is thrown off with pulling chuck, and positioning sleeve is also thrown off with the keyway of pulling chuck.
Good effect of the present utility model is: guarantee machining center main shaft is reliably strained cutter, and location and the machining accuracy of cutter are intact; Instrument cost is low, easy to operate.

Detailed description of the invention
Describe an embodiment of the present utility model in detail below in conjunction with accompanying drawing.
The utility model embodiment as shown in Figure 1, comprises screw rod 1, positioning sleeve 2; Screw rod 1 one end has thread segment 1a, and the other end has handle 1b; Positioning sleeve 2 columnar hollows, one end has protruding key 2a, and the other end has handle 2b; Screw rod 1 packs in positioning sleeve 2, rotating screw bolt 1 handle 1b, and screw rod 1 can freely rotate in positioning sleeve 2.
When use, first the protruding key 2a of positioning sleeve 2 is inserted in the keyway J3 of main spindle broach chuck J of vertical machining centre tool-broaching mechanism, the endoporus through positioning sleeve 2 screw rod 1 again, with hand rotating screw bolt handle 1b, screw rod 1 thread segment 1a tightens in the screw thread J2 that screws in pulling chuck J; Afterwards, pulling chuck J is installed on main spindle broach bar; Rotation positioning sleeve 2, makes pulling chuck screw thread J1 and the complete positive connection of main spindle broach bar; Finally, screw rod 1 is counter-rotated with pulling chuck J and thrown off, positioning sleeve 2 is also thrown off with the keyway J3 of pulling chuck J, complete machining center main spindle broach chuck J and be installed to the work on main spindle broach bar.
