Abstract
The utility model discloses a laser alignment device of a single crystal furnace, which comprises a laser scope sight and an upper shell, wherein the laser scope sight is installed in a lower shell through a washer and the upper shell is fixedly connected with the lower shell through a set screw. Since laser is used for alignment and the focused laser light spot is small and can be adjusted, the alignment is more intuitive and accurate and the operation is more convenient and rapid.
Description
Technical field
The utility model relates to a kind of debugging apparatus, particularly a kind of adjustment and precision single crystal growing furnace laser alignment more accurately device of being easy to.
Background technology
Single crystal growing furnace need carry out a series of debugging to single crystal growing furnace before actual production, according to the requirement of crystal pulling technique, must carry out the centering of upper and lower transmission during debugging, guarantees that the right alignment of seed shaft and crucible shaft is lower than certain standard value.At present, debugging centering is adopted the naked eyes estimation algorithm, promptly after hanging up weight on the seed crystal rope, weight is dropped to seeding position and the approximate place that contacts of graphite pallet, and the people assesses from the visual observation window.This method, very big because of people's subjective factor exists to the estimation error of value, directly have influence on the quality of crystal bar.
The utility model content
The purpose of this utility model provides a kind of adjustment and precision single crystal growing furnace laser alignment more accurately device of being easy to.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of single crystal growing furnace laser alignment device is characterized in that: comprise laser aiming mirror, upper housing, the laser aiming mirror is installed in the lower housing by packing ring, and upper housing is connected with lower housing by the holding screw fixed form.
The beneficial effects of the utility model are, because the utility model adopts laser alignment, and laser facula focuses on little and can adjustment, so accuracy of alignment is accurately directly perceived more, it is more convenient to operate.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Embodiment
According to embodiment the utility model is described in further detail below.
As shown in Figure 1, with reference to accompanying drawing, the laser alignment device comprises laser aiming mirror 3, and tetrafluoro packing ring 4 is installed on the laser aiming mirror 3, and is installed in 5 li of lower housings by tetrafluoro packing ring 4, and upper housing 2 is connected with lower housing 5 by holding screw 6 fixed forms.
Principle of the present utility model is: the laser alignment device is threaded with weight 1, drops to measure by seed shaft to be fit to the position, and the light beam that the laser aiming mirror sends penetrates by the aperture 7 of lower housing, plays the measurement of carrying out accuracy of alignment at the center of graphite pallet 8.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to embodiment of the present utility model.For those of ordinary skill in the field, can also make other multi-form variation and changes on the basis of the above description.Here can't give exhaustive to all embodiments.Everyly belong to the row that conspicuous variation that the technical solution of the utility model amplifies out or change still are in protection domain of the present utility model.
