A lead screw is disposed on a supporting frame, a nut is in threaded connection with the lead screw, the stepping motor is connected with the lead screw through a transmission mechanism, a driving rod is fixedly connected with the nut, two ends of the driving rod respectively contact with a first sine rod and a second sine rod, one end of a first resetting spring is fixedly connected with the first sine rod, and one end of a second resetting spring is fixedly connected with the second sine rod. The double-drive sine generator utilizes one motor to drive two sine generators so as to drive the two gratings to rotate to realize light split, and is favorable for increasing precision as the two gratings rotate simultaneously, rotating angles of the two gratings are identical and wave lengths of light split by the gratings are identical. Simultaneously, by means of utilizing one motor, volume of a spectrophotometer can be reduced, thereby reducing cost and bringing more convenience for controlling.
Description
Technical field
The utility model relates to a kind of optical instrument, in particular, and the two sine mechanisms that drive that relate to use in a kind of spectrophotometer.
Background technology
At present, in spectrophotometer, the beam split of grating realizes by the mode that the motor-driven sine mechanism drives the grating rotation.In the existing beam splitting system, each grating is driven by sine mechanism of a motor-driven.When using double grating in the beam splitting system, owing to need two motor-driven, two cover sine mechanisms, the equipment profile strengthens, the cost height, and, adopt two driven by motor, two cover sine mechanisms, control is inconvenient.
The utility model content
The utility model is in order to overcome weak point of the prior art, to provide a kind of and drive two gratings rotations simultaneously by a motor, control conveniently, can improving two sine mechanisms that drive of spectrophotometer precision.
The utility model is achieved through the following technical solutions:
A kind of two sine mechanism that drives, it is characterized in that, comprise first sine bar, second sine bar, stepper motor, leading screw, screw, driving stem, bracing frame, first back-moving spring, second back-moving spring, described leading screw is arranged on the bracing frame, described screw is connected with threads of lead screw, described stepper motor is connected with leading screw by gear train, described driving stem is fixedlyed connected with screw, the two ends of described driving stem contact with second sine bar with first sine bar respectively, described first back-moving spring, one end is fixedlyed connected with first sine bar, the other end is fixedlyed connected with the spectrophotometer base, described second back-moving spring, one end is fixedlyed connected with second sine bar, the other end is fixedlyed connected with the spectrophotometer base, and first back-moving spring is opposite with the elastic force direction of second back-moving spring.
Between first sine bar and driving stem, be provided with first drive block of fixedlying connected, between second sine bar and driving stem, be provided with second drive block of fixedlying connected with driving stem with driving stem.
The utlity model has following technique effect:
Of the present utility model pair drives two sine mechanisms of sine mechanism motor-driven of employing, rotates the realization beam split thereby drive two gratings, owing to two gratings rotate simultaneously, and the corner unanimity, the optical wavelength unanimity that grating is told helps improving precision.Simultaneously, use a motor, can reduce spectrophotometric overall volume, reduce cost, control more convenient.
Description of drawings
Fig. 1 is the two synoptic diagram that drive sine mechanism of the utility model.
Among the figure:
1. first sine bar, 2. first drive blocks, 3. leading screws, 4. screws, 5. driving stems
6. bracing frame 7. stepper motors 8. second drive blocks 9. second sine bars
10. second back-moving spring, 11. first back-moving springs.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
The synoptic diagram of the two driving of the utility model sine mechanism comprises first sine bar 1, second sine bar 9, stepper motor 7, leading screw 3, screw 4, driving stem 5, bracing frame 6, first back-moving spring 11, second back-moving spring 10 as shown in Figure 1.Leading screw 3 is arranged on the bracing frame 6, and screw 4 is threaded with leading screw 3.Stepper motor 7 is connected with leading screw 3 by gear train, and driving stem 5 is fixedlyed connected with screw 4, and the two ends of driving stem 5 contact with second sine bar 9 with first sine bar 1 respectively, are used for promoting respectively first sine bar and second sine bar.First back-moving spring, 11 1 ends are fixedlyed connected with first sine bar 1, and the other end is fixedlyed connected with the spectrophotometer base.Second back-moving spring, 10 1 ends are fixedlyed connected with second sine bar 9, and the other end is fixedlyed connected with the spectrophotometer base.First back-moving spring is opposite with the elastic force direction of second back-moving spring.Wherein, the gear train between stepper motor and the leading screw can be in belt gear, chain-drive mechanism, the gear drive any.
In order to ensure stability of transmission, between first sine bar 1 and driving stem 5, be provided with first drive block 2 of fixedlying connected with driving stem, between second sine bar 9 and driving stem 5, be provided with second drive block 8 of fixedlying connected with driving stem.
During use, stepper motor drives leading screw and rotates, and leading screw drives screw and moves along leading screw, thereby drives driving stem and the equidirectional motion of screw.When driving stem was mobile to the left, driving stem promoted first sine bar and turns left, and first back-moving spring is stretched, and simultaneously, second back-moving spring that is stretched resets, and second sine bar is turned left synchronously.When driving stem moved right, driving stem promoted second sine bar and turns right, and second back-moving spring is stretched, and simultaneously, first back-moving spring that is stretched resets, and first sine bar is turned right synchronously.Constantly repeat said process, realize adopting two sine mechanisms of a motor-driven, control more convenient.
Although relate to a kind of two sine mechanism that drives and carried out special description disclosed with reference to embodiment, embodiment described above is illustrative and not restrictive, under the situation that does not break away from spirit and scope of the present utility model, all variations and modification are all within scope of the present utility model.
