When the first clutch member 41 is in the locked position, the piston body 221 is adjacent to the flange 212 along the axial direction D, and the first clutch member 41 abuts and engages the second clutch member 43 along the axial direction D. The fixed ring gear 441 restricts the first clutch member 41 from rotating around the rotation axis L1, and the first clutch member 41 restricts the second clutch member 43 from rotating around the rotation axis L1. Therefore, the adapter 53 cannot rotate relative to the housing unit 1 , so that the steering head 6 cannot rotate to fix the position of the steering head 6 .

It can be seen from this that when the direction of the steering head 6 needs to be changed, as long as the working fluid is injected into the chamber 25 to move the first clutch member 41 to the disengaged position, the driving motor 71 can be operated to rotate the steering head. 6 to a designated position, and then stop injecting the working fluid, the first clutch member 41 will be biased by the compression springs 451 to engage the second clutch member 43 and the fixed ring gear 441 to fix the steering head 6 Location.

It is worth noting that in other variations of this embodiment, the limiting member 44 may only have the positioning pins 442, and the positioning pins 442 penetrate the first clutch member 41 and the housing body. 12, at this time, the limiting member 44 can also limit the first clutch member 41 from rotating around the rotation axis L1.

The functions and effects that the steering head 6 of this embodiment can achieve at different steering positions are further described below.

Referring to Figure 1, the central axis L2 of the mounting portion 62 extends horizontally. At this time The spindle steering device combined with the spindle 8 can be used as a horizontal spindle.

Referring to Figure 11, when the steering head 6 rotates 90 degrees relative to the housing unit 1, the central axis L2 of the mounting portion 62 extends up and down. At this time, the spindle steering device combined with the spindle 8 can be used as a vertical spindle. It can be seen from this that the spindle steering device of the present invention can easily and quickly change the spindle 8 between the vertical direction and the horizontal direction, so that it can be used as a vertical spindle or a horizontal spindle, and can be applied to linear grinders or rotary grinders. In addition, the spindle 8 can also be converted to other angles to greatly expand the range of processing applications.

To sum up, the new spindle steering device of the present invention has a smaller piston structure formed by the piston member 22 surrounding the fixed seat 21, and the shoulder screws 225 are used to connect the protrusions 223 of the piston member 22 and the The first clutch 41 enables the drive unit 7, the piston unit 2 and the clutch unit 4 to be combined compactly, reducing the movement space required when the mounting base 5 rotates, and greatly reducing the axial size of the spindle steering device. and radial dimensions. In addition, the structure of the spindle steering device is simple and the overall weight is reduced to improve the mobility and precision of the steering head 6, so the purpose of the present invention can indeed be achieved.
