[0034] The rotating hole 10 is internally provided with a plurality of shaft sleeves 34 sleeved on the outer wall of the rotating shaft 11.
[0035] The use method of the utility model is as follows:
[0036] Before the position of the tail seat needs to be adjusted, the clamping plate 13 needs to be moved downwardly first, at this time, the rotating shaft 11 can be rotated through the rotating head 12; since the outer wall of the rotating shaft 11 is provided with a clamping key 22 matched with the keyway 21 of the inner wall of the eccentric hole 20, when the rotating shaft 11 rotates, the eccentric sleeve 19 will rotate synchronously, and the axis of the circular outer wall of the eccentric sleeve 19 is different from the axis of the eccentric hole 20, in this case, the eccentric sleeve 19 will rotate eccentrically.
[0037] The existence of eccentric hole 20 makes the thickness of eccentric sleeve 19 different, one end of eccentric sleeve 19 is thick, and the other end is thin, at the same time, the outer wall of eccentric sleeve 19 is attached to the inner wall of lifting head 17, therefore, when eccentric sleeve 19 rotates eccentrically in the inner hole of lifting head 17, lifting head 17 moves up and down in lifting groove 15, thereby driving pull rod 18 to move up and down, when pull rod 18 moves down, clamping plate 13 loses the upward pulling force, the upper surface of clamping plate 13 is no longer tightly pressed on the lower surface of sliding rail 8, at this time, tailstock body 401 of tailstock can move left and right along sliding rail 8, realizing the position adjustment of tailstock, after tailstock body 401 of tailstock moves to the actual required position, rotating shaft 11 can be rotated again through rotating head 12, at this time, rotating shaft 11 moves lifting head 17 upward through the eccentric rotation of eccentric sleeve 19, thereby pulling rod 18 pulls clamping plate 13 upward, at this time, the upper surface of clamping plate 13 is tightly pressed on the lower surface of sliding rail 8, and the groove bottom of sliding groove 6 is tightly pressed on the upper surface of sliding rail, forming a stable clamping force, which firmly fixes tailstock body 401 on sliding rail 8, realizing the position fixation of tailstock.
[0038] As can be seen from the above, the utility model only needs to rotate rotating shaft 11 through rotating head 12 exposed to the outside, so as to pull clamping plate 13 upward through pull rod 18, form a stable and effective clamping force, fix the adjusted position, rotate the rotating shaft at the same time, loosen clamping plate 13, so that tailstock body 401 can freely move along the track of sliding rail 8, thereby adjusting tailstock body 401 to the actual required position, the entire adjustment and fixation operation after adjustment can be completed only by rotating the rotating shaft, which greatly simplifies the adjustment process, reduces a large amount of time for adjustment, effectively guarantees the adjustment efficiency, realizes the effect of efficient adjustment, and can avoid the situation that the screws are easily loosened due to the weight of tailstock body 401.
[0039] The limiting structure comprises an annular step 23 arranged on the inner wall of the left end hole of rotating hole 10, the outer wall of the left part of rotating shaft 11 is provided with a limiting part 24 matched with annular step 23, limiting groove 9 is provided with a limiting seat 25 matched therewith, the center of limiting seat 25 is provided with a movable hole 26, the left end of rotating shaft 11 passes through movable hole 26 to the left, limiting part 24 is located between the right side wall of limiting seat 25 and the right step surface of annular step 23, the outer edge of limiting seat 25 is provided with a plurality of evenly distributed counterbores 27, the groove bottom of limiting groove 9 is provided with a plurality of screw holes 28 coaxial with counterbores 27, only by screwing the screws through counterbores 27 into screw holes 28, limiting seat 25 can be fixed in limiting groove 9, this fixing mode is convenient for dismounting limiting seat 25, thereby facilitating the dismounting of rotating shaft 11, and the existence of limiting seat 25 can limit rotating shaft 11 to rotate only and cannot move axially along the track of rotating hole 10.
[0040] The outer wall of the rotating head 12 is a regular hexagon, and the rotating head 12 can be rotated by using a sleeve wrench matched therewith, so as to facilitate the rotation of the rotating shaft 11.
[0041] The tail seat body 401 is provided with a plurality of clamping blocks 29 on the lower surface of the tail seat body 401, and the clamping blocks 29 are connected to the lower surface of the tail seat body 401 by a plurality of screws. Therefore, the force applied by the upper surface of the clamping block 29 to the lower surface of the slide rail 8 can be adjusted by loosening the screws. When the clamping plate 13 is tightly pressed against the lower surface of the slide rail 8, the upper surface of the clamping block 29 can be tightly pressed against the lower surface of the slide rail 8 by tightening the screws, thereby achieving the effect of auxiliary fixation and further ensuring the stability of the tail seat body 401 when it is fixed.
[0042] The clamping plate 13 is provided with a through hole 30 in the center, and the lower end of the pull rod 18 passes through the through hole 30 and is screwed with a limiting nut 31 located below the clamping plate 13.
