- the pressing means of the drawer pressing down lever is provided with the one side of the pressing down lever.
- the spring means is formed as a pressing spring for urging one arm of the pressing down repeller formed on the Perck-shaped lever toward the force. I like it.
- FIG. 1 is a perspective view showing a machining center provided with a conventional spindle device
- FIG. 2 ' is a sectional view of a main part of the spindle device shown in FIG. 1
- FIG. FIG. 4 is a cross-sectional view showing a main part of a spindle device of the machining center
- FIG. 4 is a plan view of a main part of the spindle device shown in FIG.
- a spindle device of a machining center is a worktable. It is equipped with a spindle head 10 that moves up and down above the head.
- the spindle head 10 is supported on the machine base 12 by a support mechanism (not shown).
- a cylindrical spindle 14 extending vertically is rotatably supported on the spindle head 10 around its central axis, and is the spindle motor not shown in FIG. 3 a spindle motor? Belt ° — It is designed to be rotationally driven through the device 14a.
- a tool receiving portion 16 for receiving a tool from an automatic tool changing device is formed at a lower end portion of the spindle 14. here
- the automatic tool changer generally includes a tool conveying means for supplying a tool directly below the main shaft 14 and a tool magazine for holding a large number of tools.
- the tool magazine is arranged at an angle to the front of the tool spindle head 10 to index the rotation of the tool magazine. Therefore, the desired one tool may be of a type in which it is positioned directly below the spindle 14.
- the tool receiving portion 16 of the spindle 14 is moved up and down by the spindle head 10]).
- a dropper 18 is provided in the spindle 14 so as to be vertically movable, and an upper end surface 18 a of the dropper 18 projects above the spindle 14.
- the dropper 18 holds a plurality of ports 20 for clamping a push-stat formed on the upper end of the tool. I have.
- the bolt 20 acts on the small-diameter inner surface of the tool receiving portion 16 and engages with the tool's push-start.
- the tool was firmly clamped to the lower end of the spindle 14, and the tool 20 moved downward with respect to the dropper 18 spindle 14. In such a case, the tool is released from the tool's plunger to release the tool from the lower end of the shaft 14.
- a plurality of disc springs 2 2 are provided between the inner peripheral surface of the main shaft 14 and the outer peripheral surface of the dropper 18 for urging the drawer 18 upward against the main shaft 14.
- the dropper 18 can be pushed up to a fixed height with respect to the main shaft 14 by a disc spring 22.
- a dropper push-down lever 24 is pivotally connected via a horizontal shaft 26.
- Layers 24 are formed in a substantially Belk-shaped shape.
- a roller 30 is provided which acts on a cam 28 provided on the machine base 12 when 0 rises to the main shaft to a predetermined height.
- the roller 30 of the hopper 24 operates the cam 28, the upper end surface 18 a of the hopper 18 is connected to the spindle 14. It has a depressed end 24a to be depressed.
- the depressed end 24 a has an arc-shaped spherical surface facing the upper surface 18 a of the drawer 18.

- the spindle head 10 when the tool is changed, the spindle head 10 is moved up together with a tool magazine (not shown), and the roller 30 of the repeller 24 is moved to the cam 28. Then, the dropper 18 is pushed down D by the push-down end 24a of the paper 24. The tool is released from the tool receiving portion 16 of the spindle 14. Then, the spindle head 10 further moves up with respect to the tool magazine, and the lower end of the spindle 1: moves above the tool. At this time, the roller 30 of the reper 24 is located above the cam 28.
- the spindle head 10 When the tool is replaced by the tool magazine and a new tool is indexed just below the spindle 14, the spindle head 10 is lowered and the new tool is moved to the tool receiving section of the spindle 14. Inserted in 1 6. In addition, as the spindle head 10 descends, the roller 30 of the hopper 24 comes in from above
- the pole 20 is engaged with the tool neck, so that the main shaft 14 and the tool and the dropper 18 are firmly connected to each other. That is, the tool is clamped at the lower end of the spindle 14.
- the spindle head 10 descends further with the tool magazine and reaches the machining preparation position.
- the spindle 14 is driven to rotate, and the tool rotates together with the spindle 14.
- the dropper 18 is firmly connected to the spindle 14 and the tool, the spindle 14 is rotated.
- the dropper 18 also rotates with the rotation of.
- the roller 30 of the reper 24 does not act on the cam 28 at the time of the force drop, the depressed end 24 a of the reper 24 is applied by the spring force of the spring 32. It is maintained at a position away from the upper end surface 18 a of the dropper 18. Therefore, the rotation of the drawer 18 is not transmitted to the reporter 24.
- the structure for transmitting the force between the dropper and the drawer is extremely simple. What? In addition, the number of parts can be reduced, the assemblability can be improved, the weight can be reduced, and an automatic tool changing device that is hard to break down can be provided. However, since the dropper and the dropper pressing down lever are separated when the spindle rotates, noise can be reduced compared to the conventional structure. .
