物に吹き付ける。 In the automatic sealing device of the present invention, when compressed air is introduced from the tool unclamping device, the connecting tube protrudes and connects with the ventilation hole at the tail end of the drawing bolt, so that the compressed air is forced into the drawing bolt. . Hereinafter, one embodiment of the automatic sealing device of the present invention will be described with reference to the drawings. FIG. 1 shows the inside of the rear end of the spindle head 1. A drawing bolt 3 is inserted into the spindle 2, and a drawing force is applied rearward (upward in the figure) by disc springs 4. Reference numeral 5 denotes a seat ring fitted to the rear end of the drawing bolt 3, and the rear end surface 5a is adjusted to be slightly higher than the rear end surface 3b of the drawing bolt 3. C 0 is a clamp
This piston 6 is a cylinder of an unclamping device (also called a tool unclamping device) CA, and this piston 6 is caused by compressed air being forced into the lower and upper chambers in the cylinder C0 from the air input of the clamp C1 and unclamping C2 . It ascends (as shown) and descends to clamp and unclamp the tool boulder (not shown) into the spindle tapered hole (not shown). That is, the lower end large diameter portion 6a of the piston 6 comes into close contact with the top surface of the seat ring 5 during unclamping, and in this state, air from the pressure source of the air blower passes through the pipe P 1 and the through hole 7a in the piston rod 7. It passes through and reaches a through hole 3a formed in the shaft center of the drawing bolt 3, and is sprayed onto the object to be cleaned during tapping work, tool exchange, etc.

れている。 The automatic sealing device of the present invention is a piston 6 that fits into the cylinder in the tool unclamping device CA.
The main part is a connecting tube 10 installed in the large diameter portion 6a of the main body. That is, this connecting tube 10 has a small diameter air blowing hole 10a at its tip, which is fitted into a sliding hole 6b of a large diameter portion 6a, and connected to a ring-shaped guide plate 11 screwed onto the entrance of the sliding hole 6b. As shown in FIG. 2, it is recessed into the sliding hole 6b by a spring 12 that is press-fitted therebetween.
The elastic force of the spring 12 causes the compressed air press-fitted into the through hole 7a in the piston rod 7 to reach the air outlet hole 10.
This is set to be smaller than the propulsive force of the connecting tube 10 toward the drawing bolt that is generated when the fuel is injected from a.

る。 Thus, in the connecting tube 10 of the present invention, when air from a compressed air source is press-fitted into the through hole 7a and is injected from the air blowing hole 10a of the connecting tube 10, the drawing bolt 3 as shown in FIG. Spring 1 is attached to the rear end 3b of
It protrudes against the elastic force of 2 and connects airtightly. As a result, compressed air is forced into the through hole 3a of the drawing bolt 3 through the connecting tube 10 and guided to the tip side. By cutting off the compressed air, the connecting tube 10 is pushed back into the sliding hole 6b by the elastic force of the spring 12 as shown in FIG. 2, and the connection between the drawing bolts 3 is severed. Incidentally, when the tool holder is unclamped, the piston rod 7 descends to press the rear end surface 5a of the seat ring 5 with the distal end surface of the large diameter portion 6a at the distal end, thereby compressing the disc springs 4. At this time, the front end surface of the connecting tube 10 is in polar contact with the rear end surface of the drawing bolt 3, but the dimensions are such that they do not abut.

ある。 The automatic sealing device of the main shaft air blower in the tool unclamping device according to the present invention is applied to the cylinder C0 of the clamp/unclamping device which unclamps the tool by pushing the rear end surface 3b of the drawing bolt 3 which is passed through the through hole 3a. A connecting cylinder 10 having a small diameter air blowing hole 10a is inserted into the sliding hole 6b in the large diameter part 6a of the piston 6 in the direction opposite to the drawing bolt by the elastic force of the spring 12, and the piston 6 The connecting cylinder 10 protrudes against the elastic force of the spring 12 by compressed air that is press-fitted into the through hole 7a of the piston 7, comes into contact with the rear end surface 3b of the drawing bolt, and airtightly connects both the through holes 3a and 10b. Since the spring force is set, simply by introducing compressed air into the connecting tube, the connecting tube will protrude against the elastic force of the spring.
It automatically connects with the through hole at the tail end of the drawing bolt, and when the compressed air is cut off, the connecting tube sinks into the large diameter part of the piston rod due to the elastic force of the spring and is easily disconnected from the drawing bolt. The effective seal structure allows connection and disconnection with the drawing bolt.
