Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of main shaft.
Fig. 3 is the structural representation of pull hook.
Detailed description of the invention
With reference to Fig. 1-Fig. 3, the utility model is described further.
A kind of yaw drive of CNC milling machine, described CNC milling machine is provided with main spindle box 1, main shaft 11 it is provided with in main spindle box 1, including the swing arm 2 being hingedly connected at main spindle box 1 and the guide plate 3 being located on described milling machine, one end of swing arm 2 is provided with roller 21, the other end connects connecting rod 22, and described roller 21 is conflicted with guide plate 3 and is connected；
Also include the spring 4 that one end is fixed on main spindle box 1, the other end is fixed in swing arm 2 by pull hook 4.
Further, described guide plate 3 is provided with the first face 31 and the second face 32 the most at grade, and the first face 31 and the second face 32 are connected by first surface 33.
Connection bar is as a drive rod, for the gripping means grips in drive shaft 11 or loosening cutter, clamping device includes the Latin tapered sleeve being fixed in described main shaft 11 and is set in helping pull a cart in Latin tapered sleeve, described help pull a cart in be provided with several balls for clamping cutter, be provided with the circular cone for making ball eject in described Latin tapered sleeve.Cutter includes handle of a knife and drill bit, and handle of a knife is provided with the annular groove adaptive with ball, when being in dress knife-like state, connecting rod 22 drives to help pull a cart and moves upward, interior ball of helping pull a cart is ejected by the inwall of Latin tapered sleeve, makes ball just be opened on the annular groove of cutter, then ball just can be with clamping handle of a knife；When being in withdrawing state, connecting rod 22 drives to help pull a cart and moves downwardly to ball and can hide the position to circular cone, then just make cutter easily extract in main shaft 11；
When for withdrawing state: driving means drive shaft case 1 continues to rise, so roller 21 in swing arm 2 enters to the second face 32 from first surface 33, one end is connected has swing arm 2 position of roller 21 to change, so other end of swing arm 2 drives to help pull a cart by connecting rod 22 and moves downward, the interior each ball that makes to help pull a cart just conceals on circular cone, then cutter just can be extracted easily；
When for dress knife-like state: driving means drive shaft case 1 continues to decline, so roller 21 in swing arm 2 enters to the first face 31 from first surface 33, one end is connected has swing arm 2 position of roller 21 to change, so other end of swing arm 2 drives to help pull a cart by connecting rod 22 and moves upward, the interior each ball that makes to help pull a cart just blocks cutter, then cutter is just clamped on main shaft 11.
The utility model drives main spindle box 1 to move up and down by driving means, and what swing arm 2 roller 21 was connected with guide plate 3 conflict under the effect of spring 4 always, therefore, roller 21 is during guide plate 3 rises or falls, being teetered by swing arm 2 drives connecting rod 22 to move up and down, and then achieve connecting rod 22 automatically drive clamping device locking or loosening cutter, improve the speed of aligned cutting tool.
Also include the spring 4 that one end is fixed on main spindle box 1, the other end is fixed in swing arm 2 by pull hook 4, and the two ends of pull bar 41 are threaded connection with hook 42 respectively, in the long course of work, spring 4 is elongated, and causes roller 21 not conflict with guide plate 3 always and is connected, now, rotating hook 42, back-moving spring 4, makes roller 21 conflict with guide plate 3 always and is connected, and then prevents from roller 21 from can not conflict with guide plate 3 being connected and cause the loosening phenomenon generation of equipment always.
Further, the installing hole for installing connecting rod 22 it is provided with in described main shaft 11, described installing hole includes the 111, first hole, hole, location 112 and the second hole 113 being sequentially communicated, and the aperture in hole 111, location is more than the aperture in the first hole 112, and the aperture in the first hole 112 is more than the aperture in the second hole 113.
Connecting rod 22 needs at main shaft 11 internal motion, therefore, the installing hole for installing connection bar it is provided with in main shaft 11, described installing hole includes the 111, first hole, hole, location 112 and the second hole 113 being sequentially communicated, the aperture in hole 111, location is more than the aperture in the first hole 112, the aperture in the first hole 112 is more than the aperture in the second hole 113, and the aperture in the second hole 113 is identical with the external diameter of connection bar, inwall in the first hole 112 adds lubricating oil with the outer wall connecting bar, produce oil film, reduce frictional force when making connection bar drive, prevent mechanical wear.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, those skilled in the art carries out common variations and alternatives in the range of technical solutions of the utility model all should be included in protection domain of the present utility model.
