Description

Technical Field

[0001] The utility model relates to the technical field of optical splitters, in particular to a positioning fixture for an LED optical splitter. Background Art

[0002] A spectrometer is a device that grades and screens products by weight. Under the action of wind conveying, the material passes through the fan and the feed hopper and falls onto the high-speed rotating material distribution plate. Under the action of centrifugal force, the material is fully dispersed and thrown to the buffer ring. During the falling process, the heavier material passes through the blades of the adjustment ring under the action of the cross airflow generated by the rotor, slides into the coarse material collector of the sorter, and is collected, and then discharged through the fan. LED spectrometer is also a type of spectrometer, so a positioning fixture for LED spectrometer is required.

[0003] When operators need to use a spectrometer for positioning, they often use a corresponding positioning fixture for an LED spectrometer. Although the existing fixture can achieve the purpose of positioning, in actual use, it is often used to position the two ends or both sides of the object. This operation method may cause unstable positioning and subsequent shaking. In addition, the heights of the positioned objects are different, and the positioning mechanism is mostly a fixed mode, which cannot meet the positioning needs of objects of different heights, and its practicality is reduced.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The positioning fixture of the LED spectrometer is used in daily life. The operator starts the positioning motor. The operation of the positioning motor causes the lead screw to rotate, thereby driving the sleeve to slide on its surface. At this time, the sleeve drives the adjusting rod to slide. Subsequently, the adjusting rod drives the slider to slide inside the long groove and on the surface of the round rod, thereby driving the moving rod to slide.

An adjusting rod 10 is hinged between the slider 9 and the sliding sleeve 4, and a moving rod 11 is fixedly installed on the top of the slider 9. When the slider 9 slides, it will drive the moving rod 11 to slide. A vertical plate 12 is fixedly installed on the top of the moving rod 11, and a strip groove 13 is opened on the opposite surface of the vertical plate 12. A threaded rod 14 is rotatably installed inside the strip groove 13, and a block 15 is threadedly sleeved on the surface of the threaded rod 14. When the threaded rod 14 rotates, it will drive the block 15 to slide inside the strip groove 13.

[0021] The top of the vertical plate 12 is fixedly installed with an adjusting motor 16, and the output end of the adjusting motor 16 passes through the vertical plate 12 and is fixedly connected to the top of the threaded rod 14. When the adjusting motor 16 is running, the threaded rod 14 will rotate. The opposite surface of the block 15 is fixedly installed with a lifting plate 17. When the block 15 slides, it will drive the lifting plate 17 to slide. The opposite surface of the lifting plate 17 is provided with a storage groove 18, and the inside of the storage groove 18 is fixedly installed with a spring 19, and the opposite surface of the spring 19 is fixedly installed with a spring located in the storage groove 18. 8, the outer surface of the extrusion rod 20 is movably connected to the inner surface of the storage groove 18, and the opposite surface of the extrusion rod 20 is fixedly installed with a clamping plate 21.

The operation of the positioning motor 6 causes the screw rod 3 to rotate, thereby driving the sliding sleeve 4 to slide on its surface. At this time, the sliding sleeve 4 drives the adjusting rod 10 to slide, and then the adjusting rod 10 drives the slider 9 to slide inside the long groove 7 and on the surface of the round rod 8, thereby driving the moving rod 11 to slide, which can drive the vertical plate 12, the lifting plate 17 and the clamping plate 21 to move the object. When the clamping plate 21 reaches the surface of the object, the clamping plate 21 will drive the squeezing rod 20 to slide inside the storage groove 18, and then the squeezing rod 20 will squeeze the spring 19 and make it in a compressed state, so as to buffer the force in the positioning process and reduce the damage to the object. Finally, the operator starts the adjusting motor 16. The operation of the adjusting motor 16 will cause the threaded rod 14 to rotate, and then the threaded rod 14 will drive the block 15 to slide inside the strip groove 13, and then drive the lifting plate 17 to rise and fall, so as to meet the positioning work of objects of various heights.
