Abstract
A locking mechanism of a sampling reflector driving platform is characterized by comprising a traction electromagnet, a sheet-shaped strong magnet and a control power supply, wherein the traction electromagnet is arranged beside a supporting plate side of the sampling reflector driving platform relative to a ball screw pair ball screw of the sampling reflector driving platform, the sheet-shaped strong magnet is fixed at the head of a traction rod of the traction electromagnet, the traction electromagnet is connected with the control power supply, the traction electromagnet is provided with a recovery spring, and when the control power supply is disconnected, the sheet-shaped strong magnet) adsorbs and fixes the ball screw under the action of the recovery spring of the traction electromagnet. The invention has the characteristics of stable locking performance, simple structure and convenient operation.
Description
Technical field
The present invention relates to a kind of sampling reflective mirror driving platform, more particularly a kind of latch mechanism of sampling reflective mirror driving platform.
Background technology
Sampling reflective mirror is applied to the refreshing light III of Shanghai ray machine " light beam sampling transition components " project, finishes the sampling translation function of light path.The sampling reflective mirror system as shown in Figure 1, by supporting guide pair (comprising guide rail, slide block, track base) 1,9, back up pad 2, base plate 3, ball wire bar pair 4 (comprising ball screw, axle sleeve, screw rodb base), stepper motor 5, motor cabinet 6, driving platform latch mechanism 7 are formed with sampling reflective mirror 8, and system works is in the near vacuum environment.When system starts working, stepper motor 5 drives ball wire bar pair 4 runnings, thereby driving back up pad 2 moves, sampling reflective mirror 8 is fixed on the back up pad 2, move to the beam sampling position with back up pad 2, this moment, stepper motor 5 quit work, and began to carry out the light path experiment, experimental period generally needs several hrs, during require sampling reflective mirror 8 to be maintained fixed invariant position.Because sampling system is operated in the near vacuum environment, radiating condition is poor, and stepper motor 5 can not turn round for a long time, must shut down after sampling reflective mirror 8 arrives the sample position, therefore can't realize the locking of ball wire bar pair 4.Find that in use through behind the certain hour, ball wire bar pair 4 has certain position excursion, thereby causes sampling reflective mirror 8 to depart from the light path center, whole light beam sampling transition components is caused adverse effect.
Summary of the invention
The latch mechanism that the purpose of this invention is to provide a kind of sampling reflective mirror driving platform, this mechanism should have stable performance, simple in structure, convenience operation.
Technical scheme of the present invention is:
A kind of latch mechanism of sampling reflective mirror driving platform, it is characterized in that this latch mechanism is by tractive magnet, flaky strong magnet iron and control power supply constitute, described tractive magnet is installed with respect to the ball screw of the ball wire bar pair of described sampling reflective mirror driving platform in back up pad side side at sampling reflective mirror driving platform, described flaky strong magnet ferropexy is at the head of the towbar of described tractive magnet, described tractive magnet links to each other with a control power supply, described tractive magnet has one and recovers spring, when described control power supply disconnects, described flaky strong magnet iron) under the effect of the recovery spring of described tractive magnet, that ball screw absorption is fixing.
Described back up pad both sides all are equipped with a latch mechanism.
Described control power supply is synchronoused working with the step motor of described sampling reflective mirror driving platform.
Show that through on probation this locking device can well satisfy request for utilization, and simple in structure, and is easy to use.

Embodiment
The invention will be further described below in conjunction with drawings and Examples, but should not limit protection scope of the present invention with this.
See also Fig. 2, Fig. 2 is the structural representation of the latch mechanism specific embodiment of sampling reflective mirror driving platform of the present invention, as seen from the figure, the latch mechanism 7 of sampling reflective mirror driving platform of the present invention is by tractive magnet 72, flaky strong magnet iron 76 and control power supply 71 constitute, described tractive magnet 72 is installed with respect to the ball screw 41 of the ball wire bar pair 4 of described sampling reflective mirror driving platform in back up pad 2 sides side at sampling reflective mirror driving platform, described flaky strong magnet iron 76 is fixed on the head of the towbar of described tractive magnet 72, described tractive magnet 72 links to each other with a control power supply 71, described tractive magnet 72 has one and recovers spring, when described control power supply 71 disconnects, described flaky strong magnet iron 76 is under the effect of the recovery spring of described tractive magnet 72, and ball screw 41 absorption are fixing.
Fig. 2 is the structural representation of the latch mechanism specific embodiment of sampling reflective mirror driving platform of the present invention, the latch mechanism 7 of sampling reflective mirror driving platform is by control power supply 71, have first tractive magnet 72 and second tractive magnet 75 that recover spring, first web joint 73, second web joint 74, the first flaky strong magnet iron 76, the second flaky strong magnet iron 77 constitutes, described first web joint 73 and second web joint 74 are fixed on the both sides of the back up pad 2 of described sampling reflective mirror driving platform by screw 78, first tractive magnet 72 and second tractive magnet 75 are separately fixed at the outside of first web joint 73 and second web joint 74 by screw, the first flaky strong magnet iron 76 and the second flaky strong magnet iron 77 respectively by screw retention at the towbar head of described first tractive magnet, the 72 towbar heads and first tractive magnet 75 and relative with the ball screw 41 of sampling reflective mirror driving platform, rely on the effect of the recovery spring of tractive magnet, be adsorbed on the described ball screw 41, ball wire bar pair 4 is made of ball screw 41 and axle sleeve 42, and back up pad 2 is fixed on the described axle sleeve 42.
The present invention is simple in structure, easy to use, its simple course of work is: when stepper motor is in running order, 71 conductings of control power supply, the towbar of tractive magnet 72,75 shrinks, traction sheet strong magnet 76,77 breaks away from ball screw 41, and stepper motor 5 drives ball wire bar pair 4 runnings, and drive back up pad 2 and sampling reflective mirror 8 arrive the beam sampling position; After adjusting the position, stepper motor 5 stalls, control power supply 71 disconnects, under the effect of tractive magnet 72,75 spring forces, towbar is got back to reference position, and flaky strong magnet iron 76,77 is adsorbed on the ball screw 41 once more, owing to the effect of flaky strong magnet iron is all arranged in back up pad 2 both sides, the more effective ball screw that guaranteed can not produce position excursion, and the actual result that uses proves that this locking device can well satisfy request for utilization.
