When the sliding seat 30 and the diagonal pressure cylinder 40 move When moving downward to a predetermined position, the first piston rod 22 stops, and then as shown in FIG. 6, the oblique cylinder 40 acts, and the second piston rod 41 moves the chuck module 60 obliquely downwards, so that The axial direction of the workpiece 96 is opposite to the workpiece chuck (not shown in the figure) of the spindle unit 94. When the workpiece chuck is displaced and clamps the workpiece 96, the chuck module 60 can release the workpiece 96 Clamping, the feeding operation of the workpiece 96 is completed, and then, the diagonal pressing cylinder 40 and the vertical pressing cylinder 20 act in reverse order, so that the chuck module 60 leaves the workpiece diagonally upward and vertically upward in sequence The path of the displacement of the chuck, the centering lathe 90 can start processing the workpiece 96.

The present invention can move the workpiece 96 vertically and obliquely downward from above to enter between the tool unit 92 and the spindle unit 94 through the original structure, and set the workpiece 96 on the workpiece chuck. The present invention cooperates The overall configuration of the walk-through lathe 90 does not occupy a plane area in space, and does not adversely affect the repair or maintenance of the walk-through lathe 90.

As shown in Figures 2, 3, and 7, in this example, the oblique cylinder 40 is provided with a socket 42 on the side adjacent to the sliding seat 30, and the socket 42 is bored with a plurality of long grooves 43, The two ends of each of the long grooves 43 respectively point to the top and bottom ends of the socket 42, and a plurality of locking bolts 44 are pivoted through each of the long grooves 43 to be locked on the sliding seat 30, according to which the oblique pressure cylinder 40 The connecting seat 42 is assembled on the sliding seat 30, the sliding seat 30 is embedded with a connecting block 32 at the bottom end, the connecting block 32 extends to the connecting seat 42, the connecting block 32 is pivoted with an adjusting bolt 34, The adjusting bolt 34 is screwed to the socket 42 to adjust the socket 42 to move up and down along an oblique path; furthermore, the socket 42 is provided with a connecting portion 45 opposite to the connecting block 32, and the adjusting bolt 34 The connecting portion 45 is screwed.

If the axial length of the workpiece 96 is short, when the workpiece chuck moves toward the chuck module 60, the workpiece chuck may touch the connecting block 50 or the second piston rod 41. At this time, the connecting block A second chuck module of another specification (not shown in the figure) with a longer length in the vertical direction can be replaced below 50. The clamping jaws of the second chuck module are 50 in the vertical direction from the connecting block. To prevent the workpiece chuck from touching the connecting block 50 or the second piston rod 41, at this time, after loosening the locking bolt 44, the adjusting bolt 34 can be rotated to make the socket 42, the oblique The pressing cylinder 40 and the connecting block 50 are displaced upwards obliquely, so that the jaws of the second chuck module can move upwards to face the workpiece chuck in the horizontal direction. When the connecting seat 42, the oblique pressing cylinder 40 and the connecting block 50 are moved to the required position, each of the locking bolts 44 is locked, and the feeding operation can be started; thereby, the workpiece chuck moves to the second chuck module to clamp the When the workpiece is 96, the workpiece chuck will not touch the connecting block 50 or the second piston rod 41, which ensures the reliability and safety of the feeding operation.
