[0027] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.
[0028] Reference Figure 1 、 Figure 2 As shown, a high-precision gemstone grinding device includes a U-shaped seat 1, a swing seat 2, a stone sticking rod 3, a lifting linear module 4, a grinding mechanism 5, a drip cooling mechanism 6, and a base 7. The bottom of the lifting linear module 4 is slidably matched with the top surface of the base 7. The U-shaped seat 1 is arranged on the lifting linear module 4 for left and right rotation. The swing seat 2 is arranged on the front end of the U-shaped seat 1 for up and down rotation. A rotating shaft 21 is rotatably provided in the swing seat 2.

The grinding mechanism is arranged on one side of the swing seat 2 for grinding the gemstone on the stone sticking rod 3, and the drip cooling mechanism is arranged on one side of the grinding mechanism 5 for cooling and cleaning the grinding mechanism 5.
[0029] Reference Figure 2 As shown, specifically, the lifting linear module 4 includes a longitudinal slide rail 41, a longitudinal screw rod 42 is rotatably provided on the longitudinal slide rail 41, a lifting seat 43 is slidably provided on the longitudinal slide rail 41, and is threadedly connected to the longitudinal screw rod 42, and the U-shaped seat 1 is hinged on the lifting seat 43, and an adjusting hand wheel 44 is fixedly provided on the top of the longitudinal screw rod 42, so that the height of the lifting seat 43 can be adjusted by rotating the adjusting hand wheel 44, and a slide groove 71 is provided on the top surface of the base 7, and a T-shaped slider is fixedly provided on the bottom of the longitudinal slide rail 41, so that the T-shaped slider and the longitudinal slide rail 41 are in contact with the slide. The groove 71 is slidably fitted, and the T-shaped slider is connected to the longitudinal slide rail 41 by a handle screw, so that when the handle screw is turned in the reverse direction, the T-shaped slider moves relative to the direction of the longitudinal slide rail 41, so that the longitudinal slide rail can move in a straight line along the slide groove on the base, thereby adjusting the distance between the stone sticking rod and the polishing mechanism to ensure that the gem can be polished on the polishing mechanism. When the handle screw is turned in the forward direction, the T-shaped slider moves toward the longitudinal slide rail 41, thereby using the T-shaped slider to lock the longitudinal slide rail 41 on the base 7 to prevent the longitudinal slide rail 41 from moving.
[0030] Reference Figure 2 、 Figure 3As shown, the front end of the rotating shaft 21 has a socket, and the sticking stone rod 3 is inserted into the socket of the rotating shaft 21. A connecting hole connected to the socket is provided on the outer wall of the rotating shaft 21, which is threadedly connected to the connecting hole through a locking component. In this embodiment, the locking component is preferably a screw, so that the sticking stone rod in the socket is tightened by tightening the locking component to fix the sticking stone rod on the rotating shaft 21, and the front end surface of the rotating shaft 21 has a slot, and a limiting block is fixedly provided on the side wall of the sticking stone rod 3, so that when the sticking stone rod 3 is inserted into the socket, the limiting block of the sticking stone rod 3 cooperates with the slot stop. On the one hand, the deflection of the sticking stone rod 3 can be limited. On the other hand, when the sticking stone rod needs to be temporarily removed during the grinding process and then reinserted into the rotating shaft 21, the cooperation between the limiting block and the slot can be used to ensure that the angle of the sticking stone rod is consistent with the previous angle.
[0031] A scale wheel 22 is fixedly provided at the end of the rotating shaft 21 at the front end of the swing seat 2. In this embodiment, the outer periphery of the scale wheel has teeth. A clamping mechanism 23 is provided on the swing seat 2 for clamping the scale wheel 22, and a fine-tuning mechanism 24 is provided on one side of the swing seat 2 to be linked with the clamping mechanism 23. The fine-tuning mechanism 24 drives the clamping mechanism 23 to push the scale wheel 22 to rotate at a small angle. In this embodiment, the rotating seat 21 can replace the scale wheel 22 with different numbers of teeth according to the production requirements of the gemstone, making it more applicable.
[0032] Combine Figure 5 As shown, specifically, the clamping mechanism 23 includes a pressing plate 231 and a compression spring 232. The middle part of the pressing plate 231 is rotatably arranged above the swing seat 2. The top surface of the swing seat has a receiving groove. The compression spring 232 is arranged on the receiving groove of the swing seat 2 and conflicts with the end of the pressing plate 231. A locking tooth 233 is fixedly provided on the front end of the pressing plate 231, so that the rear end of the pressing plate 231 is lifted up under the elastic action of the compression spring 231, so that the locking tooth 233 on the pressing plate 231 is pressed down and engages with the teeth of the scale wheel 22, thereby preventing the rotating shaft 21 from rotating.
[0033] In addition, a rotating handwheel 213 is fixedly provided at the end of the rotating shaft 21, so that the operator can lift the front end of the pressing piece 231 upwards to disengage the tooth 233 on the pressing piece 231 from the scale wheel 22, so that the rotating shaft 21 can rotate freely. Therefore, by turning the rotating handwheel 213 to drive the rotating shaft 21 to rotate, the gem on the sticky stone stick 3 rotates with the rotating shaft 21 until a suitable angle is found, thereby changing the rotation angle of the gem. Finally, the operator releases the pressing piece 231, so that the pressing piece 231 is reset under the elastic action of the compression spring 232, and the rear end of the pressing piece 231 is lifted up so that the tooth 233 on the pressing piece 231 continues to engage with the scale wheel 22.
[0034] In this embodiment, a locking seat 26 is fixedly provided on the top surface of the rear end of the swing seat 2, and a locking screw 261 is threadedly connected to the locking seat 26 to make the locking screw 261 cooperate with the rear end of the pressing piece 231, and the top surface of the rear end of the pressing piece 231 is an inclined surface. When the rotating shaft needs to be rotated flexibly for a long time, the locking screw 261 is rotated to move it straightly toward the direction of the pressing piece and gradually press the rear end of the pressing piece 231, so that the front end of the pressing piece 231 swings upward, thereby utilizing the locking screw 261 to prevent the pressing piece 231 from resetting under the elastic action of the compression spring 232, so that the locking teeth on the pressing piece 231 can be separated from the scale wheel for a long time, thereby realizing long-term flexible rotation of the rotating shaft.
[0035] Combine Figure 6 、 Figure 7 As shown, further, the fine-tuning mechanism 24 includes a screw shaft 241 and an adjusting hand wheel 242. Support plates 25 are provided on both sides of the swing seat 2. The screw shaft 241 is rotatably set between the support plates 25. The middle part of the pressing plate 231 is threadedly connected to the screw shaft 241, and the adjusting hand wheel 242 is fixedly set at one end of the screw shaft 241. By rotating the adjusting hand wheel, the screw shaft 241 is driven to rotate, thereby linking the pressing plate 231 to move slightly in the horizontal direction, so that the scale wheel 22 is pushed by the locking teeth 233 of the pressing plate to rotate a small angle, so that small angle adjustments can be made when polishing gems, greatly improving the polishing accuracy of gems, and in this embodiment, the end face of the adjusting hand wheel 242 is provided with a plurality of scale lines equidistantly along the circumference, and a pointer piece 251 is fixedly provided on the top of the support plate 25, so that the pointer on the adjusting hand wheel 242 is positioned by the pointer piece 251 to ensure more accurate angle adjustment.
[0036] Reference Figure 1 、 Figure 4 As shown, further, an angle adjustment mechanism 11 is provided on the side of the U-shaped seat 1, and the angle adjustment mechanism 11 is linked with the swing seat 2. The angle adjustment mechanism 11 includes an angle detection module 111, a worm 112, and a worm gear 113. The rear end of the swing seat 2 is fixed with a support shaft 27 on both sides, and the support shaft 27 is rotatably connected to the front end side wall of the U-shaped seat 1, so that the swing seat 2 can swing up and down around the U-shaped seat 1. The worm gear 113 is rotatably provided on one of the support shafts 27, and the worm 112 is rotatably provided on the side wall of the U-shaped seat 1 and meshes with the worm gear 113. The worm 112 is rotated to rotate the worm gear 113, thereby adjusting the angle of the swing seat 2. At the same time, the worm gear 113 and the worm 112 are used to achieve self-locking to prevent the swing seat 2 from swinging down under the action of its own weight. The angle detection module 111 is fixedly installed on the U-shaped seat 1, and one of the shafts 27 is fixedly connected to the angle detection module 111. In this embodiment, the angle detection module 111 preferably adopts an encoder, so that the angle detection module 111 is used to obtain the swing angle of the swing seat 2, so as to adjust the angle of the swing seat 2 more accurately.
[0037] Reference Figure 3 As shown, in this embodiment, a strip groove 234 is provided on the pressing plate 231, and a bending handle 28 passing through the strip groove 234 is provided on the swing seat 2, so that the swing seat 2 can be pushed to swing up and down around the U-shaped seat, or to swing left and right around the lifting seat 43 through the bending handle 28, and when the pressing plate 23 pushes the scale wheel to rotate, the strip groove 234 can be used to avoid the bending handle, thereby avoiding interference between the bending handle 28 and the pressing plate 23.
[0038] Furthermore, an angle limiting shaft 114 is fixedly provided on the end face of the worm wheel 113, and an angle stopper 271 which cooperates with the angle limiting shaft 14 is fixedly provided on the support shaft 27. When the worm 112 links the worm wheel 113 to drive the angle limiting shaft 114 to rotate a certain angle, due to the self-locking effect of the worm wheel 113 and the worm 112, the angle stopper 271 on the swing seat 2 is blocked by the angle limiting shaft 114 when it rotates to a certain angle, thereby ensuring that the swing seat 2 reaches the specified angle.
[0039] Reference Figure 1 As shown, the grinding mechanism 5 includes a grinding disc, which is rotatably arranged on a base 7. A rotary drive device is fixedly installed inside the base 7. In this embodiment, the rotary drive device preferably adopts a motor, and its output shaft is fixedly connected to the grinding disc, so that the grinding disc is driven to rotate by the rotary drive device, so that the surface of the gemstone contacts the grinding disc, and the surface of the gemstone is ground by the grinding disc.
[0040] Reference Figure 1 As shown, this embodiment also includes a display module 8, which is electrically connected to the angle detection module 111. The display module preferably adopts a display screen for displaying the swing angle of the swing seat obtained by the angle detection module 111. In this embodiment, when the center line of the rotating shaft 21 is perpendicular to the grinding disc, the center line of the rotating shaft 21 is zero and overlaps with the angle 0 line of the angle detection module 111. When the swing seat 2 swings upward or downward around the U-shaped seat 1, the angle between the center line of the rotating shaft 21 and the angle 0 line of the angle detection module is a, so that the angle value of angle a is calculated by the angle detection module 111 and fed back to the display module 8, so that the operator can read the adjustment angle of the gem more intuitively.
[0041] Furthermore, when there is a deviation in the angle of the gem or a small angle adjustment is required, the worm gear 113 can be rotated by an angle β through the worm 112, and the angle detection module calculates the angle a'=a+β (or a-β) and feeds it back to the display module 8, so that the angle of the swing seat 2 can be fine-tuned using the angle adjustment mechanism 11, making the angle adjustment of the gem more accurate.
[0042] In another embodiment, the display module 8 is not limited to being disposed on the base 7, but may also be disposed on the U-shaped base 1 or the lifting linear module 4, thereby greatly reducing the size of the device and saving space.
[0043] Reference Figure 2 As shown, in this embodiment, a height detection module 9 is provided on the side wall of the longitudinal slide rail 41. The height detection module includes a digital scale. When the operator adjusts the lifting seat to rise or fall, the digital scale captures the displacement signal generated by the relative movement of the lifting seat, and converts the displacement signal into a digital display on the display screen of the digital scale, thereby accurately controlling the grinding depth of the gemstone to ensure that the operator can achieve the point and line joining operation of the facet during the gemstone grinding process.
[0044] Reference Figure 1 As shown, the drip cooling mechanism 6 includes a dripping kettle, which is mounted on a base 7. In this embodiment, the dripping kettle is used to store liquid, and a dripping port is provided at the bottom of the dripping kettle. The dripping port is connected to a dripping pipe extending to the top of the grinding disc, so that the dripping pipe can deliver the liquid in the dripping kettle to the surface of the grinding disc, thereby reducing the surface temperature of the grinding disc and flushing the debris on the surface of the grinding disc, so that the surface of the gem is ground more smoothly.
[0045] In addition, a water retaining groove is provided on the top surface of the base 7 below the grinding disc, and a water retaining cover is provided on the water retaining groove. The water retaining cover can prevent the liquid on the surface of the grinding disc from being thrown out, so as to ensure that the liquid flows into the water retaining groove and ensure a clean and tidy working environment.
