The operator can rotate the rotating block 3271 to allow the two sliding blocks 326 to move closer to or away from each other on the rotating rod 327.

[0043] The clamping assembly 32 further includes a first clamping platform 321 and a second clamping platform 322. The first clamping platform 321 is set on one of the sliding blocks 326 by screws, and the second clamping platform 322 is set on the other sliding block 326 by screws. Semi-elliptical clearance grooves 3217 are provided on the opposite sides of the first clamping platform 321 and the second clamping platform 322, and a first table 3211 is provided on the side of the first clamping platform 321 facing the second clamping platform 322, and a second table 3221 is provided on the side of the second clamping platform 322 facing the first clamping platform 321, and the first table 3211 and the second table 3221 are both located on the upper end surfaces of the first clamping platform 321 and the second clamping platform 322.

In the embodiment of the present application, the first clamping platform 321 and the second clamping platform 322 are both plate-like structures, and the widths of the first clamping platform 321 and the second clamping platform 322 are respectively greater than the widths of the two sliding blocks 326, that is, when the first clamping platform 321 and the second clamping platform 322 are abutted, there is a gap between the two sliding blocks 326, and they are not abutted together.

[0044] The first clamping platform 321 and the second clamping platform 322 are both detachably connected to a pressing plate 328 on one side away from the sliding block 326. When the oval bracelet is placed on the placement table 323, the operator can install the pressing plate 328 on the first clamping platform 321 and the second clamping platform 322 to flatten the oval bracelet, so that the oval bracelet can be placed horizontally on the placement table 323, and the oval bracelet is flush with the upper end surfaces of the first clamping platform 321 and the second clamping platform 322, thereby reducing the uneven polishing and easy falling off of the oval bracelet caused by being away from the placement table 323.

[0045] The first clamping platform 321 and the second clamping platform 322 are both integrally formed with a positioning column 3212 on one side away from the sliding block 326, and are both provided with a threaded groove 3213, and the side of the pressing plate 328 facing the first clamping platform 321 and the second clamping platform 322 is respectively provided with a positioning groove 3281 and a positioning screw 3282 corresponding to the positioning column 3212 and the threaded groove 3213, and the positioning screw 3282 is threadedly connected with the pressing plate 328.

[0046] join Figure 1 and Figure 4 The clamping assembly 32 also includes a driving assembly 33, which is used to drive the mounting platform 31 to move along the X-axis and the Y-axis. The driving assembly 33 includes an X-axis screw module 331 and a Y-axis screw module 332. The X-axis screw module 331 includes an X-motor 3311, an X-screw 3312, an X-block 3313 and an X-seat 3314. The cross section of the X-seat 3314 is a "concave"-shaped structure, and the X-seat 3314 is set on the frame 1 by screws. The X-motor 3311 is set on the outer side of the side plate of the X-seat 3314 by screws, one end of the X-screw 3312 is transmission-connected to the X-motor 3311, and the other end is rotationally connected to the side plate of the X-seat 3314, and the X-block 3313 is threadedly connected to the X-screw 3312. The Y-axis screw rod module 332 includes a Y motor 3321, a Y screw rod 3322, a Y block 3323 and a Y seat 3324. The cross section of the Y seat 3324 is a "concave"-shaped structure, and the Y seat 3324 is set on the X block 3313 by screws. The Y motor 3321 is set on the outer side of the side plate of the Y seat 3324 by screws, one end of the Y screw rod 3322 is connected to the Y motor 3321 by transmission, and the other end is connected to the side plate of the Y seat 3324 by rotation, and the Y block 3323 is threadedly connected to the Y screw rod 3322, and the Y block 3323 is connected to the mounting platform 31 by screws. In the embodiment of the present application, the length directions of the X screw rod 3312 and the Y screw rod 3322 are perpendicular to each other, and the lengths of the X screw rod 3312 and the Y screw rod 3322 are the same.

[0047] The implementation principle of Example 1 of the present application is as follows: when polishing the inner ring of the oval bracelet, the operator first rotates the rotating block 3271, and the rotating rod 327 rotates accordingly, so that the two sliding blocks 326 move away from each other on the mounting plate 325, and the two sliding blocks 326 drive the first clamping platform 321 and the second clamping platform 322 to move away from each other, so as to place the oval bracelet horizontally on the first table 3211 and the second table 3221, and then rotates the rotating block 3271 again, so that the first clamping platform 321 and the second clamping platform 322 move away from each other. The first table 3211 and the second table 3221 are brought close together to form a placement table 323 for placing the oval bracelet; then, the operator installs the pressing plate 328 on the first clamping platform 321 and the second clamping platform 322, and rotates the positioning screws 3282 to make the pressing plate 328 press the oval bracelet flatly on the placement table 323, and at the same time make the oval bracelet flush with the upper end surfaces of the first clamping platform 321 and the second clamping platform 322, and then removes the pressing plate 328 from the first clamping platform 321 and the second clamping platform 322;

[0048] Next, the transmission motor 211 is started, and the transmission motor 211 drives the grinding head 22 to approach the clearance groove 3217 between the first clamping table 321 and the second clamping table 322. When the grinding head 221 is located in the clearance groove 3217, the X motor 3311 and the Y motor 3321 are started to drive the mounting platform 31 to move along the X-axis and Y-axis directions. Since the grinding head 221 is located in the clearance groove 3217, it will contact the inner ring of the oval bracelet on the placement table 323. Therefore, under the limiting action of the grinding head 221, the mounting platform 31 can only make reciprocating motion in an elliptical motion trajectory, so that the grinding head 221 can grind the inner ring of the elliptical bracelet very well; and at this time, the inner side surface of the elliptical bracelet can be located in the grinding groove 2211 of the grinding head 221, so that the grinding head 221 can grind the upper and lower ends of the inner side surface of the elliptical bracelet very well, thereby improving the grinding effect of the inner side surface of the elliptical bracelet.

[0049] Example 2

[0050] Reference Figure 5 and Figure 6 The difference between this embodiment and embodiment 1 is that each pressing plate 328 used in this embodiment has an integrally formed abutting half ring 3283 on the side facing the first table top 3211 and the second table top 3221. The abutting half ring 3283 abuts against the upper side surface of the oval bracelet to flatten the oval bracelet well on the placement table 323. At this time, the horizontal height of the upper side surface of the oval bracelet is lower than the horizontal height of the upper end surfaces of the first clamping platform 321 and the second clamping platform 322.

[0051] Reference Figure 5 and Figure 7 The first clamping platform 321 and the second clamping platform 322 are both provided with installation chambers 3222, and the installation chambers 3222 are provided on both sides of the first clamping platform 321 and the second clamping platform 322, and the installation chambers 3222 of the two are on the same horizontal plane. A first pressing plate 3214 is slidably provided in the installation chamber 3222 of the first clamping platform 321, and a second pressing plate 3223 is slidably provided in the installation chamber 3222 of the second clamping platform 322. Both the first pressing plate 3214 and the second pressing plate 3223 can slide in the direction of approaching or moving away from the placement table 323.

[0052] One side of the first pressing plate 3214 and the second pressing plate 3223 extends out from the installation chamber 3222 and is in a semi-elliptical shape, which can abut against the upper side of the oval bracelet. In the embodiment of the present application, the width of the first pressing plate 3214 and the second pressing plate 3223 extending from the installation chamber 3222 is less than the thickness of the oval bracelet, so as not to affect the polishing of the inner ring of the oval bracelet. The first pressing plate 3214 and the second pressing plate 3223 are also provided with a buffer plate 32143, and a buffer spring 32141 is bonded to one side of the buffer plate 32143, and the other side of the buffer spring 32141 is bonded to the inner wall of the installation chamber 3222. The first pressing plate 3214 and the second pressing plate 3223 are formed with a mounting channel 3215 on one side away from the oval bracelet, and the ends of the first pressing plate 3214 and the second pressing plate 3223 are convenient to extend from the mounting channel 3215.

[0053] join Figure 7 and Figure 8 The first pressing plate 3214 and the second pressing plate 3223 extend out of the installation channel 3215 at one end away from the oval bracelet, and abutment ports 32142 are provided on both sides of the first pressing plate 3214 and the second pressing plate 3223. A clamping plate 3216 is hingedly provided on the side walls of both sides of the installation channel 3215, and a clamping spring 32161 is bonded to the side of the clamping plate 3216 away from the first pressing plate 3214 and the second pressing plate 3223, and the side of the clamping spring 32161 away from the clamping plate 3216 is connected to the inner wall of the installation channel 3215. At this time, the end of the clamping plate 3216 close to the installation chamber 3222 abuts against the side surfaces of the first pressing plate 3214 and the second pressing plate 3223. When the first pressure plate 3214 and the second pressure plate 3223 are pressed onto the oval bracelet, at this time, the clamping plate 3216 abuts against the abutment interface 32142 of the first pressure plate 3214 and the second pressure plate 3223, and at the same time, the buffer spring 32141 is in a stretched state, giving the first pressure plate 3214 and the second pressure plate 3223 a resetting force.

[0054] When the inner ring of the oval bracelet is polished and grinded, the operator rotates the clamping plate 3216 so that the clamping plate 3216 no longer abuts against the abutment interface 32142 of the first pressure plate 3214 and the second pressure plate 3223. Then, the first pressure plate 3214 and the second pressure plate 3223 can be reset under the drive of the buffer spring 32141, so that the first pressure plate 3214 and the second pressure plate 3223 no longer press the upper side of the oval bracelet.

[0055] The implementation principle of Example 2 of the present application is as follows: when polishing the inner ring of the oval bracelet, the operator first rotates the rotating block 3271, and the rotating rod 327 rotates accordingly, so that the two sliding blocks 326 move away from each other on the mounting plate 325, and the two sliding blocks 326 will drive the first clamping platform 321 and the second clamping platform 322 to move away from each other, so as to place the oval bracelet horizontally on the first table 3211 and the second table 3221, and then rotate the rotating block 3271 again, so that the first clamping platform 321 and the second clamping platform 322 are close to each other, so that the first table 3211 and the second table 3221 are enclosed. A placement table 323 for placing the oval bracelet is formed; then, the operator installs the pressing plate 328 on the first clamping platform 321 and the second clamping platform 322, and rotates the positioning screws 3282 so that the pressing plate 328 presses the oval bracelet flatly on the placement table 323, and the abutting half ring 3283 on the pressing plate 328 abuts against the upper side surface of the oval bracelet, and at the same time makes the horizontal height of the upper side surface of the oval bracelet lower than the horizontal height of the upper end surfaces of the first clamping platform 321 and the second clamping platform 322, and then the pressing plate 328 is removed from the first clamping platform 321 and the second clamping platform 322;

[0056] Then, when the operator is preparing to push the first pressure plate 3214 and the second pressure plate 3223, at this time, the buffer spring 32141 is in a natural state, and the end of the snap-in plate 3216 close to the installation chamber 3222 abuts against the side of the first pressure plate 3214 and the second pressure plate 3223, and the snap-in spring 32161 is in a compressed state, which can drive the snap-in plate 3216 to rotate in the direction close to the abutment interface 32142; when the operator pushes the first pressure plate 3214 and the second pressure plate 3223 to slide in the installation chamber 3222, the first pressure plate 3214 and the second pressure plate 3223 slide in the direction close to the oval bracelet until the end of the first pressure plate 3214 and the second pressure plate 3223 extending from the installation chamber 3222 is pressed against the upper side of the oval bracelet, and the width of the first pressure plate 3214 and the second pressure plate 3223 extending from the installation chamber 3222 is less than the thickness of the oval bracelet. At this time, the buffer spring 32141 is in a stretched state. At the same time, as the first pressing plate 3214 and the second pressing plate 3223 slide in the installation chamber 3222, the clamping plate 3216 abuts against the abutting port 32142 under the drive of the clamping spring 32161, so as to prevent the first pressing plate 3214 and the second pressing plate 3223 from resetting.

[0057] Next, the transmission motor 211 is started, and the transmission motor 211 drives the grinding head 22 to approach the clearance groove 3217 between the first clamping table 321 and the second clamping table 322. When the grinding head 221 is located in the clearance groove 3217, the X motor 3311 and the Y motor 3321 are started to drive the mounting platform 31 to move along the X-axis and Y-axis directions. Since the grinding head 221 is located in the clearance groove 3217, it will contact the inner ring of the oval bracelet on the placement table 323. Therefore, under the limiting action of the grinding head 221, the mounting platform 31 can only make reciprocating motion in an elliptical motion trajectory, so that the grinding head 221 can grind the inner ring of the elliptical bracelet very well; and at this time, the inner side surface of the elliptical bracelet can be located in the grinding groove 2211 of the grinding head 221, so that the grinding head 221 can grind the upper and lower ends of the inner side surface of the elliptical bracelet very well, thereby improving the grinding effect of the inner side surface of the elliptical bracelet.

[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
