Description

Locking rotator

Technical Field

The invention relates to the technical field of transmission tools, in particular to a locking rotator.

Background

The rotator is an auxiliary small unit device for realizing related functions of a flexible semi-automatic system in lean management, and mainly has the function of adjusting the working state of the rotation around the shaft so as to realize special movement of related units in the system and achieve the working state required by design. Namely, in the light load occasion with small stress and force fluctuation, the related units in the flexible semi-automatic system need the rotation with slower forward direction speed and can be locked at any time, and the reverse direction needs the rotation with faster speed (such as working states of ascending and descending, climbing and descending, forward return, forward and reverse rotation and the like).

Disclosure of Invention

It is an object of the present invention to provide a locking rotator having features suitable for use in flexible semi-automatic systems.

The technical scheme adopted by the invention is as follows: the locking rotating device comprises a rotating shaft and a rotatable outer barrel which is sleeved outside the rotating shaft, an upper cover and a lower cover are fixed to the upper end of the outer barrel, a lower end of the outer barrel is fixed to the lower end of the outer barrel, the upper cover and the lower cover are respectively sleeved outside the upper end and the lower end of the rotating shaft, a lower ratchet with teeth facing upwards is fixed to the surface of the middle circumference of the rotating shaft, a screw rod penetrates through the upper cover from bottom to top, a round-head nut is screwed on the upper end of the screw rod, an upper ratchet with teeth facing downwards is sleeved on the lower end of the screw rod, and the upper ratchet is provided with a pressure spring which enables the ratchet to have a downward moving trend.

The upper end of pivot extends to the part on the upper portion of this upper cover and overlaps and be equipped with a rotatable steering wheel, and the edge of this steering wheel is equipped with the breach of opening direction along the circumference tangential direction of this steering wheel, and breach and button head nut match.

The circumferential side surface of the outer cylinder is provided with a plurality of outer grooves extending in the up-down direction.

The rotating shaft is provided with an inner cavity which is through up and down, and a plurality of inner grooves which extend in the up and down direction are arranged on the circumferential side surface of the inner wall of the inner cavity.

And a bearing is arranged between the outer cylinder and the rotating shaft.

After adopting the structure, compared with the prior art, the invention has the advantages that: suitable for application in flexible semi-automatic systems. The locking rotator can realize the relative rotation of the outer cylinder and the rotating shaft, and when the outer cylinder rotates relative to the rotating shaft, one direction can smoothly rotate, and the other direction is in a locking state. Meanwhile, after optimization, when the outer cylinder rotates to a certain angle relative to the rotating shaft through the control panel, the outer cylinder is restrained to pause rotation, and therefore the outer cylinder is in a temporary locking state. Namely, two working modes of one-way locking, one-way semi-restraint and the like around a shaft in the product work are realized, and the flexible semi-automatic locking mechanism is extremely suitable for being applied to a flexible semi-automatic system.

Detailed Description

Examples, see fig. 1-5: the locking rotator comprises a rotating shaft 10 and an outer cylinder 20 which is rotatably sleeved outside the rotating shaft 10. Of course, the outer cylinder 20 may be made longitudinally immovable relative to the shaft 10 in a variety of conventional ways.

Further speaking:

an upper cover 21 is fixed to the upper end of the outer cylinder 20 by screws or the like, and a lower cover 22 is fixed to the lower end thereof by screws or the like. The upper cover 21 and the lower cover 22 are respectively sleeved on the upper end outside and the lower end outside of the rotating shaft 10. Meanwhile, a lower ratchet 11 with its teeth facing upward is fixed on the middle circumferential surface of the rotating shaft 10. A screw 23 is arranged on the upper cover 21 from bottom to top. The upper end of the screw 23 is screwed with a round-head nut 231, and the lower end is sleeved with an upper ratchet 232 with a downward tooth form. That is, the upper ratchet 232 is provided with a through hole for the screw 23 to pass through, and since the lower end of the screw 23 necessarily has a large head, the upper ratchet 232 cannot necessarily pass downward over the large head of the screw 23, so that the upper ratchet 232 can and only can move up and down on the corresponding screw 23. The upper ratchet 232 is provided with a compression spring 233 that has a tendency to move downward. For example, the compression spring 233 is sleeved on the screw 23, and the upper and lower ends of the compression spring 233 respectively abut against the upper cover 21 and the upper ratchet 232. And, the upper ratchet 232 and the lower ratchet 11 are matched. That is, the teeth of the upper ratchet 232 and the lower ratchet 11 are engaged together, so that the upper ratchet 232 can be rotated in one direction and locked in the opposite direction compared to the lower ratchet 11. That is, since the upper ratchet 232 is not rotatable compared to the outer cylinder 20, and the lower ratchet 11 is fixed on the rotating shaft 10, the outer cylinder 20 can rotate in one direction and lock in the opposite direction compared to the rotating shaft 10.

Optimizing:

a rotatable control wheel 30 is sleeved on a portion of the upper end of the rotating shaft 10 extending to the upper portion of the upper cover 21. Preferably, the control wheel 30 is rotatable in comparison with the spindle 10, but by means of a stop device, the control wheel 30 can be temporarily locked intermittently in comparison with the spindle 10. Meanwhile, the edge of the control wheel 30 is provided with a notch 31 having an opening direction along the circumferential tangential direction of the control wheel 30, and the notch 31 should be oriented opposite to the upper ratchet 232 in a unidirectional rotation direction compared to the lower ratchet 11. The notch 31 mates with the round head nut 231. That is, although the outer cylinder 20 can rotate in one direction compared to the rotating shaft 10, once the round-head nut 231 hits or enters the corresponding notch 31, the outer cylinder 20 can be locked in clearance compared to the rotating shaft 10 until the operating panel 30 is rotated again, and then the corresponding round-head nut 231 is released from the notch 31. In this way, another mode of operation of unidirectional half-restraint is achieved.

And (4) continuing optimization:

the outer cylinder 20 is provided on its circumferential side with a plurality of outer grooves 24 extending in the up-down direction. The rotating shaft 10 has an inner cavity 12 penetrating up and down, and a plurality of inner grooves 121 extending in up and down directions are provided on the inner wall circumferential side of the inner cavity 12. Thus, it is convenient to connect different parts to the outer cylinder 20 and the rotation shaft 10, respectively.

A bearing 40 is provided between the outer cylinder 20 and the rotating shaft 10. The bearings 40 may be a plurality of bearings in which the inner ring is fitted on the rotating shaft 10 and the outer ring is caught on the inner wall of the outer cylinder 20, and adjacent bearings 40 may be spaced apart by a dividing sleeve to ensure that the adjacent bearings 40 have a constant interval. Thus, the outer cylinder 20 can rotate smoothly with respect to the rotating shaft 10.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
