Abstract
The utility model provides a linear motor controlled entrance slit system, which comprises an entrance slit light transmitting rack fixed on a frame. The entrance slit light transmitting rack is provided with a center slit, a slit plate fixing plate is arranged between the entrance slit light transmitting rack and the square frame and embedded in the entrance slit light transmitting rack, a slit plate is fixed on the slit plate fixing plate, the square frame is vertically fixed on a fixed board, the fixed board is mounted on a guide rail which is fixed on a horizontal plate of a baseboard, a vertical plate of the baseboard is provided with a through hole, a motor is fixed on the outer side of the vertical plate of the baseboard, a motor lead screw penetrates in the through hole, the end of the motor lead screw is fixedly connected with a stopper, the stopper is fixed with one end of the fixed board along the guide rail, and a limit switch mount is arranged on the horizontal plate of the baseboard at the other end of the guide rail. The linear motor controlled entrance slit system has the advantages that the position of the entrance slit system can be controlled by the linear motor, and running steps of the linear motor are controlled by a computer, so that position dimension of the entrance slit can be controlled accurately.
Description
Technical field
The utility model relates to a kind of entrance slit system, especially a kind of entrance slit system of linear electric motors control.
Background technology
Entrance slit is a critical component of photo-electric direct reading spectrometer the inside, and the exciting light on the excited sample platform is mapped on the concave grating by entrance slit, and grating becomes spectrum line with photolysis, each element in these spectrum line representative samples.Entrance slit plays the accurate positioning action of light, and general now employing ruler is taken measurements, and screw retention is difficult to guarantee its precision like this.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of linear electric motors to control the entrance slit system, realizes the accurate control of entrance slit.
The technical scheme that provides according to the utility model, described linear electric motors control entrance slit system comprises: be fixed on and go into to stitch the printing opacity frame on the framework, go into to stitch the printing opacity frame and have the centre joint, crack sheet fixed head is going into to stitch between printing opacity frame and the quadra, be embedded in the seam printing opacity frame, the crack sheet is fixed on the crack sheet fixed head, described quadra vertically is fixed on the fixed head, fixed head is installed on the guide rail, guide rail is fixed on the leveling board of base plate, the vertical plate of base plate is provided with through hole, motor is fixed in the vertical plate outside of base plate, and the motor screw mandrel penetrates described through hole, the fixedly connected block in motor screw mandrel end, block and fixed head are fixed along an end of guide rail, on the floor level plate of the guide rail other end limit switch mount pad are set.
Describedly go into to stitch the printing opacity frame and partly insert in the quadra, and be screwed.
Run through draw runner in the leveling board of described base plate.
On the leveling board of described base plate, also be provided with two fixed orifices.
The utility model has the advantages that: adopt the position of linear electric motors control entrance slit system, the step number (stroke) that computer control linear electric motors are walked, position dimension that can very accurate control entrance slit.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model vertical view.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, 2: these linear electric motors control entrance slit system comprises: on quadra 6, be fixed into seam printing opacity frame 7, go into to stitch printing opacity frame 7 parts and insert in the quadra 6, and fixing with screw 12.Screw 12 is arranged on the two ends on quadra 6 tops, to going into to stitch 7 fixing and regulating actions of printing opacity frame.Crack sheet fixed head 8 is going into to stitch between printing opacity frame 7 and the quadra 6, is embedded in the seam printing opacity frame 7, and be wringing fit mutually, crack sheet 9 is made up of two thin slices, constitute slit between two thin slices, two thin slices are fixed on the crack sheet fixed head 8, go into to stitch printing opacity frame 7 and have the centre joint.
Described quadra 6 vertically is fixed on the fixed head 5, fixed head 5 is installed on the guide rail 4, guide rail 4 is fixed on the leveling board of base plate 2, the vertical plate of base plate 2 is provided with through hole, motor 1 is fixed in the vertical plate outside of base plate 2, motor screw mandrel 11 penetrates described through hole, the fixedly connected block 13 in motor screw mandrel 11 ends, block 13 is fixed along an end of guide rail 4 with fixed head 5, on base plate 2 leveling boards of guide rail 4 other ends limit switch mount pad 3 is set, limit switch mount pad 3 is used to install limit switch, prevents that fixed head 5 from exceeding moving range.
Draw runner 10 is through in the leveling board of base plate 2, and draw runner 10 is fixed on the spectrometer vacuum chamber, also is provided with two fixed orifices on the leveling board of base plate 2, conveniently its position is adjusted with fixing.
This entrance slit is penetrated system and is processed complete according to the design drawing requirement, be assembled to the vacuum chamber assigned address, linear electric motors are connected to control panel, control panel is being connected with computer, during work, there is computer to provide signal and controls stroke that linear electric motors are walked, accurately locate thereby reach the entrance slit system of penetrating.
