An automatic quick locking and releasing device for an optical axis, comprising: the locking taper sleeve 1, the fixing seat 3, the upper gland 2 and the lower top cover 4.
The locking taper sleeve 1 is in a taper structure with a side opening, and is sleeved on the optical axis 10 in a fitting way through an extrusion surface at the inner end of the locking taper sleeve; the inner conical surface 11 at the inner end between the upper opening and the lower opening of the fixed seat 3 is matched with the conical surface at the outer end of the locking taper sleeve 1, so that the locking taper sleeve 1 can be arranged in a sliding way along the inner conical surface 11 of the fixed seat 3 through the conical surface at the outer end of the locking taper sleeve; the upper gland 2 and the lower top cover 4 are respectively arranged at the upper opening and the lower opening of the fixed seat 3 and can move along the axial direction of the optical axis 10; the upper gland 2 and the lower top cover 4 are respectively provided with an upper pressing part 12 and a lower top part 13 which can extend into the fixed seat 3 and are abutted against the locking taper sleeve 1.
When the optical axis 10 needs to be locked, the upper gland 2 moves downwards to enable the locking taper sleeve 1 to move downwards through the upper pressing part 12, the fixing seat 3 and the optical axis 10 are pressed at the same time, and the locking taper sleeve 1 is contracted on the optical axis 10 through pressure.
When the optical axis 10 needs to be loosened, the lower top cover 4 moves upwards to enable the locking taper sleeve 1 to move upwards through the lower top 13, the pressure between the fixing seat 3 and the optical axis 10 is reduced, and therefore the locking taper sleeve 1 is loosened from the optical axis 10.
In some embodiments, both the upper gland 2 and the lower cap 4 move in the axial direction of the optical axis in synchronization. The synchronous movement can be that the upper pressing part 12 and the lower top part 13 are just abutted against the upper end face and the lower end face of the locking taper sleeve 1 in the non-locking state, and the lower top part 13 synchronously provides a movable space when the upper pressing part 12 is pressed down due to the synchronous movement so as to ensure that the upper pressing part 12 and the lower pressing part are in a relatively stable movement state in the locking process, so that the control accuracy and stability are improved. Similarly, the principle is the same as described above when the locked state is changed to the released state.
In some embodiments, the upper cover 2 and the lower cover 4 are synchronously moved along the axial direction of the optical axis by a driving mechanism. The control by a single driving mechanism not only reduces the cost, but also ensures the synchronism.
In some embodiments, the upper gland 2 and the lower top cover 4 are respectively in threaded connection with the upper opening and the lower opening of the fixed seat 3, and the upper gland 2 and the lower top cover 4 are rotated by the threads of the upper gland 2 and the lower top cover 4, so that the upper gland 12 and the lower top 13 are abutted against the locking taper sleeve 1. The upper pressing part 12 and the lower top part 13 are in butt extrusion on the locking taper sleeve 1 in a threaded mode, the axial movement of the locking taper sleeve 1 is realized, the control accuracy is higher, and the stability and the safety of the locking taper sleeve are improved by utilizing the self-locking principle of threads.
Further, a connecting shaft is arranged between the upper gland 2 and the lower top cover 4. The upper gland 2 and the lower top cover 4 can synchronously move through the connecting shaft.
Further, the connecting shaft is externally provided with a driving unit, and the driving unit pushes the connecting shaft to drive the upper gland 2 and the lower top cover 4 to synchronously rotate. The driving unit can adopt driving structures such as a hydraulic cylinder, an electric pushing cylinder, an air cylinder and the like, and the driving purpose is achieved by pushing the connecting shaft to rotate.
In some embodiments, an upper gear 5 and a lower gear 6 are respectively arranged on the upper gland 2 and the lower top cover 4; a driving motor 7 is arranged on one side of the fixed seat 3; a driving gear 8 meshed with the upper gear 5 and the lower gear 6 is arranged on the driving shaft of the driving motor 7. The synchronous rotation driving of the upper gland 2 and the lower top cover 4 is realized through the synchronous engagement of the driving gears 8, and the transmission relationship is more reliable and stable. Meanwhile, it should be noted that the relative widths of the driving gear 8 and the upper and lower gears 5 and 6 are required to satisfy the movement stroke requirements of the upper and lower caps 2 and 4. Preferably, helical gears are used for the upper gear 5, the lower gear 6 and the driving gear 8.
Further, the upper gear 5 and the lower gear 6 are fixedly connected with the upper gland 2 and the lower top cover 4 respectively through bolts.
Further, a protective cover is arranged outside the upper gear 5 and/or the lower gear 6, and an opening is arranged at one end of the protective cover, which is close to the driving gear 8, so that the upper gear 5 and the lower gear 6 are meshed with the driving gear 8 through the opening. As shown in fig. 1 and 3, the protective cover is provided only at the lower gear 6, where the design can be chosen according to requirements.
In some embodiments, further comprising: a displacement sensing unit and a controller; the displacement sensing unit is arranged on the fixed seat 3 and used for identifying the movement position of the upper gland 2 and/or the lower top cover 4; the controller is electrically connected with the driving motor 8 and the displacement sensing unit.
Taking the locking process and the displacement sensing unit 8 as an example, when the photoelectric switch detects that the downward moving distance of the upper gland 2 reaches the moving distance of the locking state, the photoelectric switch sends a signal to control the driving motor 7 to stop driving so as to complete the locking of the optical axis 10.
In the above process, the photoelectric switch can also be used for detecting the lower top cover 4 or synchronously detecting the upper pressing cover 2 and the lower top cover 4.
Although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
