The condensing lens adjusting gear group is meshed with the condensing lens rack in the light condensing composite structure. Wherein, the automatic lifting device still comprises a limit switch, a step motor and a step motor control system. The step motor is connected with the condensing lens adjusting gear group through the coupling. The restoration standard position for the light condensing composite structure to move of up and down is ensured by the limit switch, and the limit switch is positioned on the extreme position of the journey for the microscope corresponding to the condensing lens. The limit switch and the step motor are connected with the step motor control system through the leads. The computer control system of the step motor sends out the dictate, the condensing lens adjusting gear group is rotated driven by the step motor to drive the rack to move in an up and down manner, thereby reaching the aim of driving the light condensing composite structure to move in an up and down manner to automatically adjusting position.
Description
Technical field
The utility model relates to the condenser apparatus for automatically lifting that a kind of microscope is used.
Background technology
Traditional microscope condenser elevating mechanism is by manual adjustments condenser regulating tooth wheels knob, rotating the drive tooth bar by gear moves up and down, reach and adjust the purpose that condenser moves up and down, time and effort consuming so not only, and also permanent processing ease makes the operator produce sense of fatigue.
The utility model content
The condenser apparatus for automatically lifting that the utility model provides a kind of may command condenser elevating mechanism to move up and down automatically.
In order to realize above-mentioned purpose, the utility model has been taked following solution: the condenser apparatus for automatically lifting, and it comprises optically focused composite structure, condenser regulating tooth wheels, the condenser tooth bar engagement in condenser regulating tooth wheels and the optically focused composite structure; Wherein apparatus for automatically lifting also comprises limit switch, stepper motor and step motor control system; Stepper motor links to each other with condenser regulating tooth wheels by shaft joint; The upper and lower mobile reference position that resets of optically focused composite structure is determined that by limit switch limit switch is located at the extreme position of the corresponding condenser stroke of microscope; Limit switch and stepper motor are connected with step motor control system by lead.
Being provided with one on the described optically focused composite structure can be at the switch press plate of condenser extreme limit of travel position shake-up limit switch.
Described optically focused composite structure is made up of condenser group, condenser adjustment seat, condenser carriage, condenser left and right sides dovetail slide, condenser tooth bar, the condenser group is located in the condenser adjustment seat, and the condenser adjustment seat is installed on the condenser carriage, the condenser carriage is installed in condenser dovetail slide left side, the condenser dovetail slide is installed in the slide rail of microscope frame, at the affixed condenser tooth bar in condenser dovetail slide right side.
The upper and lower mobile reference position that resets of described optically focused composite structure is the limes superiors position.
The upper and lower mobile stroke of described optically focused composite structure can be controlled by the position counting value that step motor control system is set.
After adopting such scheme; when needs are adjusted optically focused composite structure upper-lower position; send instruction by the stepper motor computer control system; driving tooth bar by the rotation of stepper motor drive condenser regulating tooth wheels moves up and down; thereby reach and drive the optically focused composite structure and move up and down and adjust the purpose of position; its limes superiors position is by the control of switch press plate and limit switch and as the reference position that resets of computer system control; and be no more than the mechanical limit position of optically focused composite structure by the stroke that the setting of position counting value can be controlled the optically focused composite structure automatically; thereby can protect the physical construction of optically focused composite structure not answer over travel and produce damage effectively; therefore the utility model has effectively been realized the function of automatic adjusting condenser upper-lower position; after using this mechanism, can also control condenser by computer remote and move up and down automatically.

Embodiment
At first shown in Fig. 2,3, apparatus for automatically lifting of the present utility model is made up of optically focused composite structure A, condenser regulating tooth wheels B, limit switch C, stepper motor D and step motor control system E (seeing shown in Figure 1);
Optically focused composite structure A comprises parts compositions such as condenser group 1, condenser adjustment seat 2, condenser carriage 3, condenser dovetail slide 4, condenser tooth bar 5, switch press plate 6; Condenser group 1 is located in the condenser adjustment seat 2, and condenser adjustment seat 2 is installed on the condenser carriage 3, condenser carriage 3 is installed in condenser dovetail slide 4 left sides, condenser dovetail slide 4 is installed in the slide rail E of microscope frame, at the affixed condenser tooth bar 5 in condenser dovetail slide 4 right sides, switch press plate 6 is located at condenser carriage 3 tops;
Condenser regulating tooth wheels B comprises gear 7 and gear shaft 8; Gear shaft 8 one ends link together with stepper motor D by shaft joint 9, and the other end connects manual knob 9 (in the time need not using automatic regulatory function, also can regulate the upper-lower position of optically focused composite structure A by this knob); Gear 7 is that cover is fixed on the gear shaft 8, and meshes with above-mentioned condenser tooth bar 5;
Stepper motor D is fixed on the motor fixing plate 10, is installed in the bracket 11 again, and the position of corresponding above-mentioned switch press plate 6 is provided with limit switch C on support 11, lock motor cover plate 14 after, it is compact that mechanism of the present utility model seems, and do not affect the appearance;
Limit switch C and stepper motor D are connected with step motor control system E by lead.
When needs are adjusted condenser group 1 upper-lower position, send instruction by computing machine and controller E, driving condenser tooth bar 5 by stepper motor D drive condenser regulating tooth wheels B rotation moves up and down, then whole optically focused composite structure A moves up and down in the slide rail E of microscope frame, drive condenser group 1 and move up and down and adjust the purpose of position thereby reach, its extreme position is by switch press plate 6 and limit switch C control.
Again as shown in Figure 1, stepper motor can have single-chip microcomputer or motion control card to send STEP pulse and DIR direction signal with single-chip microcomputer or the motion control card E that uses a computer control, is input to stepper motor driver F, through driver F segmentation, amplification, outputs to motor.In order to realize location, limit switch C is housed in the extreme higher position of condenser group 1 stroke to condenser group 1.System powers on and carries out reset operation, and stepper motor D control condenser group 1 rises, and arrives peak, contacts limit switch C, and single-chip microcomputer or computing machine be the position counting zero clearing, and is initial point with this position.Control optically focused group 1 then and drop to normal operation position.During the condenser motion, the position of counter changes thereupon, and by the position that count value just can be obtained condenser, also the may command condenser arrives any position, is provided with bound for count value, and then account for motion beyond the mark goes beyond the scope, and motion stops.
