When described in detail with respect to the operation of the horizontal rotating unit 40,

Figure 4 is a perspective view showing a cylinder tube according to the present invention, Figure 5 is a cross-sectional view taken along line AA of Figure 4, Figure 6 is a cross-sectional view taken along line BB of Figure 4, Figure 7 is a horizontal spin of the present invention It is a state diagram in which the horizontal rotating unit is lowered to allow rotation.

The horizontal rotating part 40 is connected to the lower side of the main body 10 as a cubic coupling 35 as shown in FIGS. 2 and 3 to rotate the horizontal rotating part 40 horizontally when unclamping by the clamping means ( It is possible to pivot the horizontal spins 30 installed therein by turning).

As shown in FIGS. 4 to 7, the clamping means is coupled to the lower side of the main body 10 so that the horizontal rotating part 40 is fitted therein and a piston moving space 47 therebetween. The piston is provided to be moved up / down in the piston moving space 47 in a state in which the cylinder pipe 45 is coupled to form and the vertical spindle 25 in the upper side of the horizontal rotating portion (40) ( 50 and a first fluid movement path 55 and a second fluid movement path respectively formed in the cylinder pipe 45 to introduce fluid into the piston movement space 47 above and below the piston 50. It consists of 57.

One fluid inlet pipe 59 is connected to one side of the outer circumferential surface of the cylinder pipe 45 to allow fluid to flow into the first fluid moving path 55 and the second fluid moving path 57.

The fluid introduced through the fluid inlet pipe 59 is introduced into the piston moving space 47 formed above the piston 50 through the first fluid moving path 55 or the second fluid moving. It is introduced into the piston moving space 47 formed on the lower side of the piston 50 through the furnace (57).

In this case, the inflow of the fluid is controlled to allow the fluid to be introduced by the control by the controller to enable the movement of the piston 50, the body 10 and the horizontal rotating portion by the up / down movement of the piston 50 The cubic couplings 35 respectively fixed to the 40 are engaged with or separated from each other to guide the horizontal rotation part 40 to be horizontally rotated.

In the spindle head of the present invention configured as described above, the operation relationship of the horizontal spindle according to the present invention will be described.

First, when the unclamping hydraulic pressure is introduced into the piston moving space 47 formed on the upper side of the piston 50 through the first fluid movement path 55 in the clamped state, the piston 50 is engaged while being lowered. The tooth surfaces of the cubic coupling 35 are separated from each other, thereby causing the horizontal rotation part 40 to descend from the main body 10.

In this state, the operator rotates the horizontal rotating part 40 horizontally to position the horizontal spindles 30 at a desired angle, and then the controller controls the clamping operation.

In the clamping operation, when the clamping hydraulic pressure flows into the piston moving space 47 formed below the piston 50 through the second fluid moving path 57, the civic couple separated while the piston 50 is lifted. Tooth surfaces of the ring 35 are brought into close contact with each other, and thus the horizontal rotating part 40 is lifted and brought into close contact with the main body 10 to be clamped.

As described above, the present invention enables horizontal processing of the horizontal rotating part horizontally after the clamping operation and the unclamping operation of the horizontal rotating part, thereby making it possible to process the surface without changing the position when the workpiece is processed. You will be able to improve significantly.
