In order to ensure the coaxiality of the workpiece, the position of the hydraulic center frame 8 needs to be adjusted, and the coaxiality of the clamping arms of the hydraulic center frame 8 is ensured by adjusting the position of the hydraulic center frame.
The following explains the working mechanism and the embodiment of the supporting mechanism for lathing the long shaft according to the present invention:
locking of the sliding block 4:
the sliding of the sliding block 4 along the slideway 1 belongs to a common linear sliding structure, but the fixing of the sliding block comprises a plurality of modes, in the utility model, when the position of the sliding block 4 needs to be adjusted, the pin shaft 6b is rotated by the hand wheel 6e, the wedge block 6d is finally rotated, the wedge block 6d is separated from the slideway 1, and the sliding block 4 can be moved,
when the sliding block 4 needs to be locked, the wedge block 6d is abutted against the slideway 1 through the operation and the transmission mechanism, the wedge block 6d and the bottom plate 3b are fixed due to the fact that the wedge block 6d is compressed and wound with great friction stress, and the sliding block 4 is fixed on the bottom plate 3b, so that the limitation of the whole bearing mechanism is guaranteed.
Adjustment in the radial direction of the workpiece:
and loosening the bolt for fixing the space between the transverse adjusting plate 3c and the bottom plate 3b, then moving the transverse adjusting plate 3c, wherein the bottom plate 3b and the bolt do not move, the bolt and the oblong through hole on the transverse adjusting plate 3c slide relatively, and after the position is adjusted, the bolt is tightened.
Similarly, the adjustment of the vertical position can be achieved by loosening and tightening the bolts between the longitudinal adjustment plate 3d and the base plate 3 a.
Besides the above operations, when the position of the hydraulic center frame 8 is adjusted in the vertical direction, the long bolt 3g needs to be screwed, because the hydraulic center frame 8 has a large mass and the weight of the workpiece is pressed on the base plate 3a, in the fixing mechanism, the fixing is mainly performed through static friction between the bolt and the nut and the support of the longitudinal adjusting plate 3d, so that the long bolt can provide support for the base plate 3 a.
The supporting wheel tool 5 is used for adjusting:
when the hydraulic center frame 8 does not clamp a workpiece, the workpiece needs to be supported, meanwhile, the workpiece is guaranteed not to be abraded due to friction with the support in the feeding process, the supporting wheel tool 5 can provide support, and abrasion of the workpiece can be avoided through rotation of the supporting wheel 5 d.
The supporting wheel tooling 5 is fixed on the base plate 3a, the position of the supporting wheel tooling can be adjusted by the adjusting mode, and the adjusting mode mainly realizes the height difference adjustment of the part, which is used for embedding the workpiece, between the supporting wheel and the base plate 3a and between the supporting wheel and the hydraulic central frame 8.
Firstly, the locking bolt 5e is loosened, then the first fixing plate 5a, the second fixing plate 5b and the supporting wheel 5d which are installed on the first fixing plate 5a are adjusted along the up-down direction, then the locking bolt 5e is screwed again, the tail end of the locking bolt 5e abuts against the first fixing plate 5a to complete the fixing, and at the moment, the supporting wheel 5d needs to support the weight of the workpiece through the friction force between the locking bolt 5e and the first fixing plate 5 a.
If the number of the supporting components 2 is small, the distance between two adjacent supporting components 2 is too large, the workpiece is easy to bend, and a large load is applied to the supporting components, so that the number of the supporting components 2 needs to be selected according to the length and the specification of the workpiece.
Above-mentioned technical scheme has only embodied the utility model discloses technical scheme's preferred technical scheme, some changes that this technical field's technical personnel probably made to some parts wherein have all embodied the utility model discloses a principle belongs to within the protection scope of the utility model.
