Description
Technical field
The present invention relates to a kind of positioning fixture, be specifically related to heliostat four axle deflection positioning fixture.
Background technology
Tower type solar energy thermal power generation utilizes thousands of heliostats to be reflexed to by sunshine on the central receiver of reception top of tower, and the working medium added in hot receiver makes it to produce steam driven steam turbine, electrical power generators.Only has the change of heliostat accurate tracking position of sun, guarantee solar facula energy accurately gathers on receiver, and ensure that the key of the accurate solar tracking of heliostat is heliostat registration, namely the position coordinates of heliostat is wanted accurately, therefore requires also more strict to the positioning fixture of heliostat.
And existing heliostat locator meams is the rotating manner of position angle+angle of pitch, the method has larger machinery firmly spacing, is unfavorable for protecting mirror, and also can produce certain period out of control in actual motion, reliability is lower, and corrects with maintenance cost higher.
Summary of the invention
The present invention proposes heliostat four axle deflection positioning fixture, and this apparatus structure is simple, can accurately locate heliostat position, and not scratch heliostat locating surface.
The present invention realizes above-mentioned purpose by following technology: heliostat four axle deflection positioning fixture, it is characterized in that: comprise base plate, eccentric bushing, synchronous excentric shaft, diamond positioning pin, eccentric bushing is positioned on base plate, and synchronous excentric shaft is positioned at eccentric bushing inside, and diamond positioning pin is fixed on base plate by the fixed pin be provided with.
Eccentric bushing, the synchronous excentric shaft of described heliostat four axle deflection positioning fixture have four, and the center of circle of four eccentric bushings is on the same circle being the center of circle with base plate center.
The eccentric bushing of described heliostat four axle deflection positioning fixture is provided with synchronous excentric shaft locator card.
The invention has the beneficial effects as follows: this apparatus structure is simple, easy to operate, heliostat position can be located accurately, solid and reliable, and by regulating the distance between four synchronous excentric shafts, the workpiece of fixing different size, adaptability is good, in large-scale workpiece position fixing process, do not scratch Workpiece fixing surface, consistance is high, and efficiency is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of heliostat four axle deflection positioning fixture;
Fig. 2 is the side view of heliostat four axle deflection positioning fixture.
Wherein, 1-base plate, 2-eccentric bushing, the synchronous excentric shaft of 3-, 4-diamond positioning pin, 5-fixed pin.
Embodiment
Below by specific embodiment, the invention will be further described, heliostat four axle deflection positioning fixture, it is characterized in that: comprise base plate 1, eccentric bushing 2, synchronous excentric shaft 3, diamond positioning pin 4, eccentric bushing 2 is positioned on base plate 1, it is inner that synchronous excentric shaft 3 is positioned at eccentric bushing 2, diamond positioning pin 4 is fixed on base plate 1 by the fixed pin 5 be provided with, the eccentric bushing 2 of described heliostat four axle deflection positioning fixture, synchronous excentric shaft 3 has four, the center of circle of four eccentric bushings 2 is on the same circle being the center of circle with base plate 1 center, the eccentric bushing 2 of described heliostat four axle deflection positioning fixture is provided with synchronous excentric shaft locator card.
When the fixing heliostat of needs, heliostat is placed in the top of heliostat four axle deflection positioning fixture diamond positioning pin 4, and coordinate with diamond positioning pin 4, the preliminary fixing of position is carried out to heliostat, again four synchronous excentric shafts 3 are fitted in the external margin of heliostat, now heliostat is fixed further by four synchronous excentric shafts 3, when heliostat size changes, by rotating four synchronous excentric shafts 3 simultaneously, and turn to applicable angle, by locator card, synchronous excentric shaft 3 is fixed, change the relative distance between synchronous excentric shaft 3, now diamond positioning pin 4 and four synchronous excentric shafts 3 coordinate the heliostat can fixing different size.
