Because the upper grinding wheel and the lower grinding wheel are symmetrically arranged, the component force of the cutting force in the vertical direction is counteracted, the component force of the cutting force in the longitudinal direction is in the Y-axis negative direction, and the limiting plate 22 limits the moving freedom degree of the Y axis, so that the crystal glass rod can rotate in the anticlockwise axial direction during processing.
The grinding device has the advantages that the two grinding wheels are used for grinding together, and the efficiency is high. And because the vertical component force of the cutting force is offset, the crystal glass rod can be prevented from deforming, thereby improving the processing precision and better protecting the damage of the bearing.

As shown in fig. 6, the blanking device 5 includes a blanking motor 51, a belt 52, a blanking frame 53 and a support rod 54. The support rod 54 is transversely arranged, the right end of the support rod 54 is connected with the blanking motor 51 through a support plate, the middle part of the support rod 54 is connected with the blanking frame 53, and the left part of the support rod 54 is fixedly connected with the frame 1. The belt 52 has a right end connected to the driving shaft 521 and a left end connected to the driven shaft 522. The driving shaft 521 is connected with the blanking motor 51. The driven shaft 522 is connected with the support rod 54 through a support plate. The blanking frame 53 is arranged at the front part of the support rod 54, and a through hole is arranged at the top part.
When the blanking machine works, the blanking motor 51 drives the belt 52 to move through the driving shaft 521. When grinding device 4 resets, when stopping the grinding, unloading motor 51 starts, and drive belt 52 motion, belt 52 carries the crystal glass stick of a processing completion to unloading frame 53 top through the friction mode, under the effect of gravity, the crystal glass stick falls into the unloading frame, then unloading motor 51 stops, after that under loading attachment 3's promotion, the crystal glass stick of processing completion can be pushed away belt 52 on stop device 2, because belt 52 motionless can produce frictional force this moment, through frictional force and loading attachment 3's motive force, fix the crystal glass stick of waiting to process in the middle of stop device 2. Until the next grinding device 4 is reset, the next cycle of the conveying process is started again.
The blanking device has the advantages that automatic conveying and collection can be realized, and the degree of freedom of movement of the X axis of the crystal glass rod is limited under the combined action of friction and the feeding device 3. The conveying is stable, the well is orderly, the structure is simple, and the efficiency is high.
In summary, the automatic crystal glass rod grinding machine integrates automatic feeding, automatic grinding and automatic discharging, crystal glass rods on the feeding device 3, the limiting device 2 and the discharging device 5 are positioned on the same straight line, when the feeding device 3 and the discharging device 5 stop moving, friction between the crystal glass rods and the belt 52 and friction between the crystal glass rods to be processed and the toothed belt 36 limit movement of the crystal glass rods, an upper grinding wheel and a lower grinding wheel limit rotation of an Y, Z shaft and movement of a Z shaft during processing, and movement of the Y shaft is limited through the limiting plate, so that only rotation of the X shaft is left. Through the symmetrical arrangement of the upper grinding wheel and the lower grinding wheel, the vertical component force for counteracting the cutting force is realized to protect the crystal glass rod, and the rotation of the crystal glass rod is realized through the speed difference of the upper grinding wheel and the lower grinding wheel, so that the automatic rotary feeding is realized. The common grinding action of the upper grinding wheel and the lower grinding wheel greatly improves the efficiency. The whole grinder has high efficiency and good grinding precision, can adapt to crystal glass rods with different thicknesses, and can randomly select the position to be processed.
Because the crystal glass rods 6 on the feeding device 3, the limiting device 2 and the discharging device 5 are on the same axis, under the pushing action of the feeding device 3 and the friction action of the crystal glass rods, the crystal glass rods to be processed and the processed crystal glass rods limit the freedom degree of movement of the crystal glass rods to be processed in the X direction. The feeding device 3 stops feeding, at this time, the upper grinding wheel 413 is started and rotates clockwise, the lower grinding wheel 423 is started and rotates anticlockwise, and under the action of the two groups of sliding adjusting modules, the lower grinding wheel moves to a neutral position between the left clamping plate and the right clamping plate simultaneously and is positioned at the upper side and the lower side of the crystal glass rod to be processed, so that the moving freedom degree and the Y, Z rotating freedom degree of the crystal glass rod to be processed in the Y-axis direction are limited. The limiting plate 22 limits the freedom of movement in the Y direction, thereby only the freedom of rotation of the X axis of the crystal glass rod to be processed is left. After that, grinding is started, and due to the limitation of all degrees of freedom, the machining precision is ensured as long as the distance between the upper grinding wheel and the lower grinding wheel is ensured. Because the rotating speed of the upper grinding wheel is greater than that of the lower grinding wheel and the X-axis rotational freedom degree is not limited, the crystal glass rod rotates anticlockwise, and the rotary feeding motion is completed. And after the grinding process is finished, the upper grinding wheel and the lower grinding wheel reset and stop. The blanking device 5 is started and stopped after blanking is finished. The loading device 3 is then activated, whereby the next cycle is started. The automatic feeding device is characterized in that the feeding device 3 is capable of automatically feeding materials and stable in feeding, the limiting device 2 and the grinding device 4 act together to limit each degree of freedom of the crystal glass rod, automatic rotary feeding is achieved while accuracy is guaranteed, external power sources are not required to be added, and automatic discharging and collection are achieved through the discharging device 5. By the symmetrical arrangement of the upper grinding wheel 413 and the lower grinding wheel 423, the component force of the cutting force in the vertical direction is counteracted in the grinding process, the crystal glass rod is prevented from jumping and deforming during processing, the grinding precision is ensured, and the grinding efficiency is improved by the common grinding of the upper grinding wheel and the lower grinding wheel.
