The inner bottom wall of the metal bottom shell 30 is processed to form a colorful concave pattern. Since the surface of the light-transmitting workpiece 20 is transparent and convex, the pattern of the inner bottom wall of the metal bottom shell 30 can be made more ornamental. With the improvement of people's living standards, the market demand for such accessories is growing.

[0003] In order to improve the quality of the light-transmitting workpiece 20, it can be adapted and installed with the metal bottom shell 30, so it is necessary to grind the rotating raised top wall 21 and the cylindrical outer wall 22.

[0037] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings show preferred embodiments of the present invention.

[0038] like Figures 1 to 6As shown, a light-transmitting handicraft polishing device 10 includes a machine table 100, a material carrier 200 and a polishing assembly 300. The material carrier 200 is rotatably arranged on the machine table 100, and the material carrier 200 is used to fix the light-transmitting workpiece 20 and drive the light-transmitting workpiece 20 to rotate cyclically. The polishing assembly 300 includes a downward pressing driving member 310, a polishing seat 320, a first polishing block 330, a first elastic member 340, a second polishing block 350 and a second elastic member 360. The downward pressing driving member 310 is provided The grinding seat 320 is placed on the machine 100, and is arranged on the output shaft of the downward pressing driving member 310. The downward pressing driving member 310 is used to drive the grinding seat 320 to approach or move away from the material carrier 200. The first grinding block 330 is slidably arranged in the grinding seat 320 along the axial direction. The bottom end of the first grinding block 330 is provided with a first grinding surface 3321 adapted to the raised top wall 21. The first elastic member 340 is respectively in contact with the first grinding block 330 and the grinding seat 320. The first elastic member 340 is in contact with the first grinding block 330 and the grinding seat 320. The first grinding block 330 is extended from the bottom end of the grinding seat 320 by pushing the first grinding block 330. The second grinding block 350 is obliquely slidably arranged on the first grinding block 330. A second grinding surface 3521 is arranged on one side of the second grinding block 350. The second elastic member 360 abuts against the second grinding block 350 and the first grinding block 330 respectively. The second elastic member 360 is used to push the second grinding block 350 so that the second grinding block 350 abuts against the grinding seat 320. When the driving member 310 is pressed down, When it is used to drive the grinding seat 320 to approach the carrier 200, the first grinding surface 3321 first abuts against the raised top wall 21 of the light-transmitting workpiece 20, and the second grinding surface 3521 then abuts against the cylindrical outer wall 22 of the light-transmitting workpiece 20; when the downward driving member 310 is used to drive the grinding seat 320 away from the carrier 200, the second grinding surface 3521 first moves away from the cylindrical outer wall 22 of the light-transmitting workpiece 20, and the first grinding surface 3321 then moves away from the raised top wall 21 of the light-transmitting workpiece 20.

[0039] It should be noted that the light-transmitting workpiece 20 is fixed by the material carrier 200 and driven to rotate continuously, and the polishing assembly 300 is used to polish the raised top wall 21 and the cylindrical outer wall 22 of the light-transmitting workpiece 20, which are both rotating surface structures. Specifically, the pressing drive 310 is used to drive the polishing seat 320 to approach or move away from the material carrier 200. For example, the pressing drive 310 can use a manipulator in the prior art to drive the polishing seat 320 to move. In the present application, a screw module combination is provided to drive the polishing seat 320 to move. The first screw module is installed on the machine 100, and the second screw module is installed on the output shaft of the first screw module, wherein the first screw module is used to drive the second screw module to perform a linear reciprocating motion along the horizontal plane, and the polishing seat 320 is installed on the output shaft of the second screw module, and the second screw module is used to drive the polishing seat 320 to perform a reciprocating lifting motion along the vertical direction. Furthermore, the grinding seat 320 is fixedly mounted on the output shaft of the second screw module by means of screws. In this way, driven by the downward pressure driving member 310, the grinding seat 320 can be close to or away from the material carrier 200. When the grinding seat 320 is close to the material carrier 200, the light-transmitting workpiece 20 is ground. Specifically, an inner cavity extending along the axial direction is provided in the axial direction of the grinding seat 320, and the first grinding block 330 is adaptively slidably mounted in the inner cavity of the grinding seat 320, so that the first grinding block 330 can slide along the axial direction of the grinding seat 320. The two ends of the first elastic member 340 respectively abut the first grinding block 330 and the grinding seat 320, wherein the first elastic member 340 can be a coil spring. Under the elastic thrust of the first elastic member 340, the first grinding block 330 extends from the bottom end of the grinding seat 320, wherein a first grinding surface 3321 is provided on the lower end surface of the first grinding block 330, and the shape of the first grinding surface 3321 matches the shape of the raised top wall 21 of the light-transmitting workpiece 20. Further, the second grinding block 350 is obliquely slidably mounted on the first grinding block 330, specifically, there is a certain angle between the sliding direction of the second grinding block 350 and the axial direction of the first grinding block 330, for example, the angle ranges from 20° to 30°, and further, the angle can be 26°. The second elastic member 360 abuts against the second grinding block 350 and the first grinding block 330 respectively, wherein the second elastic member 360 is also a coil spring. Under the elastic thrust of the second elastic member 360, the second grinding block 350 has a tendency to rise and abut against the grinding seat 320.

[0040] Thus, in the natural state, the first elastic member 340 pushes the first grinding block 330 to make it move downward relative to the grinding seat 320. The second elastic member 360 pushes the second grinding block 350 to make it move upward obliquely relative to the first grinding block 330, and finally abuts against the grinding seat 320. When the downward driving member 310 drives the grinding seat 320 to approach the material carrier 200, the material carrier 200 is fixed and drives the light-transmitting workpiece 20 to rotate continuously. When the first grinding surface 3321 abuts against the raised top wall 21 of the light-transmitting workpiece 20 for grinding, since the first grinding block 330 is limited, as the grinding seat 320 continues to descend, the first elastic member 340 is compressed, and the grinding seat 320 pushes the second grinding block 350 to slide obliquely relative to the first grinding block 330, so that the second grinding surface 3521 slides obliquely to approach and finally abut against the cylindrical outer wall 22 of the light-transmitting workpiece 20. Since the light-transmitting workpiece 20 is fixed on the carrier 200 and driven to rotate continuously, the first grinding surface 3321 grinds the raised top wall 21 of the light-transmitting workpiece 20, and the second grinding surface 3521 grinds the cylindrical outer wall 22 of the light-transmitting workpiece 20. Therefore, it is possible to simultaneously grind two connected rotating surface structures on the workpiece. Compared with the existing manual grinding method, the grinding efficiency and grinding quality of the light-transmitting workpiece 20 can be effectively improved.

[0041] like Figure 5 As shown, in one embodiment, the first grinding block 330 includes a sliding core 331 and a first grinding head 332. The sliding core 331 is axially slidably arranged in the grinding seat 320. The first grinding head 332 is detachably arranged at the bottom of the sliding core 331. The first grinding surface 3321 is located on the first grinding head 332.

[0042] It should be noted that, since the outer curve structure of the axial section of the raised top wall 21 of the light-transmitting workpiece 20 is different, the first grinding surface 3321 used for grinding therewith will be different. In order to be able to be used for grinding the raised top wall 21 of light-transmitting workpieces 20 of different sizes, and as the grinding time increases, the first grinding surface 3321 will be worn, in order to facilitate the replacement of parts, the first grinding block 330 is set to a structure in which a sliding core 331 and a first grinding head 332 are assembled. Specifically, the sliding core 331 is slidably mounted on the axis of the grinding seat 320, and the first grinding head 332 is detachably mounted on the bottom end of the sliding core 331 using screws. For example, the sliding core 331 adaptively slides into the inner cavity of the grinding seat 320, so that the sliding core 331 can slide relative to the grinding seat 320.

[0043] like Figure 3As shown, in one embodiment, the first grinding block 330 further includes a limiting column 333, the limiting column 333 is disposed on one end of the sliding core 331 away from the first grinding head 332, and the limiting column 333 is penetrated through the grinding seat 320 to extend from the top of the grinding seat 320, and the first elastic member 340 is sleeved on the limiting column 333. In this way, the first elastic member 340 is sleeved on the limiting column 333, and the first elastic member 340 can reliably push the sliding core 331.

[0044] like Figure 3 As shown, in one embodiment, a limiting block 334 is provided on one end of the limiting column 333 located on the outer side of the grinding seat 320 , and the limiting block 334 is used to be engaged with the grinding seat 320 .

[0045] It should be noted that, in order to prevent the sliding core 331 from sliding out of the inner cavity of the grinding seat 320, a stopper 334 is provided to engage with the grinding seat 320. Specifically, the diameter of the stopper 334 is larger than the inner diameter of the through hole through which the stopper column 333 passes through the grinding seat 320, so that the sliding core 331 will not slide out of the grinding seat 320.

[0046] like Figure 3 As shown, in one embodiment, the grinding assembly 300 also includes an adjusting rod 371 and a cross 372. A cross hole 3331 is axially opened on the limiting column 333. The cross 372 is adaptively slidably set in the cross hole 3331. One end of the first elastic member 340 close to the grinding seat 320 abuts against the cross 372. The adjusting rod 371 is screwed into the limiting column 333 along the axial direction, and the adjusting rod 371 is rotatably connected to the cross 372.

[0047] It should be noted that the above structure is provided in order to adjust the elastic force of the first elastic member 340. Specifically, by rotating the adjusting rod 371, the adjusting rod 371 is rotated relative to the limiting column 333, so that the cross 372 slides along the cross hole 3331, so that when the first grinding block 330 does not contact the raised top wall 21 of the light-transmitting workpiece 20, the total length of the first elastic member 340 is the distance between the cross 372 and the top surface of the sliding core 331, so by adjusting the distance of the cross 372 relative to the sliding core 331, the natural total length of the first elastic member 340 can be adjusted, so that the pressure of the first grinding block 330 pressing down and grinding the raised top wall 21 of the light-transmitting workpiece 20 can be adjusted, so that the raised top wall 21 of the light-transmitting workpiece 20 can be better ground.

[0048] like Figure 3 As shown, in one embodiment, one of the outer wall of the sliding core 331 and the inner wall of the grinding seat 320 is provided with a guide portion 335 , and the other is provided with a guide groove 321 , and the guide portion 335 is adaptively slidably disposed in the guide groove 321 .

[0049] It should be noted that, in order to ensure that the sliding core 331 can stably reciprocate along the axial direction of the grinding seat 320, a guide portion 335 is provided to slide adaptively in the guide groove 321 to achieve a guiding effect.

[0050] like Figure 6 As shown, in one embodiment, the second grinding block 350 includes a slider 351 and a second grinding head 352. The slider 351 is obliquely slidably disposed on a side wall of the sliding core 331. The second grinding head 352 is detachably disposed on the slider 351. The second elastic member 360 is respectively abutted against the slider 351 and the sliding core 331.

[0051] It should be noted that, since the second grinding surface 3521 will wear out over time, in order to facilitate the replacement of parts, the second grinding block 350 is configured to be assembled with a slider 351 and a second grinding head 352. Among them, a T-slot is obliquely provided on the slide core 331, and an oblique T-rail is provided on the slider 351, so that the T-rail slides in the T-slot in an adaptive manner, so that the slider 351 can slide obliquely relative to the slide core 331. The second grinding head 352 is detachably mounted on the slider 351 by screws, so that when the second grinding surface 3521 is worn, the second grinding head 352 can be directly replaced.

[0052] It should be noted that the material of the first grinding head 332 and the second grinding head 352 can be any material in the prior art. Since the grinding material is not the content that needs to be protected in this application, it will not be described here.

[0053] like Figure 1 , Figures 7 to 12 As shown, in one embodiment, the material carrier 200 includes a material carrier seat 210, a material locking rod 220, a material locking core 230, a plurality of inclined guide blocks 240 and a plurality of material clamping claws 250. A bracket 400 is provided on the machine 100. The material carrier 210 is rotatably provided on the bracket 400. Each material clamping claw 250 is radially slidably provided on the material carrier seat 210, and each material clamping claw 250 is distributed at equal angles in a circle. An inclined guide hole 251 is provided in each material clamping claw 250. The material locking core 230 is penetrated through the material carrier seat 210. Each inclined guide block 240 is obliquely and circumferentially provided on the outer side wall of the material locking core 230, and each inclined guide block 240 is slidably connected with each inclined guide hole 251 in a one-to-one correspondence. The material locking rod 220 is penetrated through the material carrier seat 210. The material locking rod 220 is used to bear force to drive the material locking core 230 to slide so that each material clamping claw 250 approaches or moves away from each other.

[0054] It should be noted that the bracket 400 is mounted on the machine 100 by screws, and the material carrier 210 is rotatably mounted on the bracket 400. Each clamping claw 250 is slidably mounted on the material carrier 210 along the radial direction. For example, a plurality of T-shaped slide grooves are provided in the radial direction of the material carrier 210, and one end of each clamping claw 250 is provided with a T-shaped slide rail, and the T-shaped slide rail is used to slide in the T-shaped slide groove in an adaptive manner, so that each clamping claw 250 can stably slide along the radial direction of the material carrier 210. Among them, each clamping claw 250 is distributed at equal angles along the circumference of the material carrier 210, and the end of each clamping claw 250 away from the T-shaped slide rail is higher than the top surface of the material carrier 210. Further, an oblique guide hole 251 is obliquely opened in the clamping claw 250. The material locking core 230 is slidably installed in the axis of the material carrier 210 along the axial direction, and each oblique guide block 240 is fixed on the outer side wall of the material locking core 230 at equal angles in the circumference, and each oblique guide block 240 passes through each oblique guide hole 251 respectively. Further, one end of the material locking rod 220 extends into the material locking core 230 from the bottom of the material carrier 210, and the other end of the material locking rod 220 is located below the material carrier 210. In this way, by applying axial thrust and pulling force to the material locking rod 220, the material locking core 230 can slide along the axial direction of the material carrier 210, so that under the cooperation of the oblique guide block 240 and the oblique guide hole 251, each material clamping claw 250 can be close to or away from each other. When each material clamping claw 250 is close to each other, the light-transmitting workpiece 20 placed on the material carrier 210 can be clamped and fixed. When the clamping claws 250 are away from each other, the light-transmitting workpiece 20 can be removed from the carrier 210. In this way, the light-transmitting workpiece 20 is fixed by the carrier 200, and when the carrier 200 is driven to rotate, the light-transmitting workpiece 20 can be driven to rotate, so that under the action of the grinding assembly 300, the convex top wall 21 and the cylindrical outer wall 22 of the light-transmitting workpiece 20 with a rotating surface structure are synchronously grinded.

[0055] like Figure 8 As shown, in one embodiment, a bottom block 23 is disposed at the bottom of the light-transmitting workpiece 20, and the carrier 200 fixes the bottom block 23 so that the light-transmitting workpiece 20 is reliably fixed.

[0056] It should be noted that since the raised top wall 21 and the cylindrical outer wall 22 of the light-transmitting workpiece 20 need to be polished, in order to facilitate the fixation of the light-transmitting workpiece 20, a bottom block 23 is reserved at the bottom of the light-transmitting workpiece 20 as an auxiliary fixing structure. After the raised top wall 21 and the cylindrical outer wall 22 are polished, the bottom block 23 can be cut off.

[0057] In one embodiment, four clamping claws 250 are provided, and four inclined guide blocks 240 are provided, and the four inclined guide blocks 240 are respectively inserted into the inclined guide holes 251 of the four clamping claws 250. In this way, the four clamping claws 250 are synchronously opened and closed to clamp and fix the light-transmitting workpiece 20.

[0058] like Figure 8 As shown, in one embodiment, the material carrier 210 is a circular structure, a rotating bearing 271 is sleeved on the outer wall of the material carrier 210, and the rotating bearing 271 is fixed on the bracket 400, so that the material carrier 210 can stably rotate relative to the bracket 400. For example, the rotating bearing 271 is a ball bearing. Further, in one embodiment, two rotating bearings 271 are provided, and a space is provided between the two rotating bearings 271.

[0059] like Figure 8 As shown, in one embodiment, a thin ring 272 is provided on the outer wall of the material carrier 210, and a pressure bearing 273 is provided on both sides of the thin ring 272, and a buckle plate 274 is buckled on the bracket 400, and the buckle plate 274 and the bracket 400 clamp the thin ring 272 and the two pressure bearings 273 together. For example, the pressure bearing 273 is a thrust ball bearing, which can withstand axial force. In this way, when the polishing assembly 300 presses down to polish the light-transmitting workpiece 20, the pressure bearing 273 can transfer the pressure borne by the material carrier 210 to the bracket 400. Avoid the rotary bearing 271 from being damaged by the axial pressure. In this way, by utilizing the cooperation of the rotary bearing 271 and the pressure bearing 273, the material carrier 210 can stably drive the light-transmitting workpiece 20 to rotate.

[0060] like Figure 7 As shown, in one embodiment, the material carrier 200 further includes a rotary driving member 260 . The rotary driving member 260 is disposed on the bracket 400 , and an output shaft of the rotary driving member 260 is connected to the material carrier seat 210 .

[0061] It should be noted that, for example, the rotating drive member 260 is a combination of a motor and a belt. The motor is installed on the bracket 400, and the pulleys are respectively fixed on the carrier 210 and the output shaft of the motor, so that the motor can stably drive the carrier 210 to rotate.

[0062] like Figure 8 , Fig.11 , Fig.12 As shown, in one embodiment, the material carrier 200 also includes a top holding plate 281, a third elastic member 282 and a top holding bearing 283, one end of the third elastic member 282 abuts against the top of the material locking rod 220, and the other end of the third elastic member 282 is connected to the top holding plate 281, and the top holding bearing 283 abuts against the top holding plate 281 and the material locking core 230 respectively, so that the material locking core 230 can rotate relative to the top holding plate 281 through the top holding bearing 283.

[0063] It should be noted that the material locking rod 220 is used to apply thrust to the material locking core 230 so that the material locking core 230 slides along the axial direction of the material carrier 210, thereby making each material clamping claw 250 approach or move away from each other. Since the material carrier 210, the material locking core 230, each inclined guide block 240 and each material clamping claw 250 need to rotate as a whole to drive the light-transmitting workpiece 20 to rotate, and the material locking rod 220 does not need to rotate. Therefore, in order to enable the material locking rod 220 to stably apply axial thrust to the material locking core 230 to ensure that each material clamping claw 250 clamps the light-transmitting workpiece 20, and at the same time make the material locking rod 220 not rotate with it, and avoid contact friction between the material locking rod 220 and the material locking core 230, the above structure is set. Specifically, the material locking core 230 is elastically connected to the material locking rod 220 through the third elastic member 282, wherein a holding piece 281 is provided at one end of the third elastic member 282 away from the material locking rod 220, and a holding bearing 283 is installed between the holding piece 281 and the material locking core 230. The holding bearing 283 is also a thrust ball bearing, so that when the material locking rod 220 is thrusted, the third elastic member 282 is compressed, and the third elastic member 282 pushes the holding piece 281, and then pushes the material locking core 230 through the holding bearing 283. In this way, the material locking core 230 and the holding piece 281 are rotated through the holding bearing 283.

[0064] like Figure 8 , Fig.11 , Fig.12 As shown, in one embodiment, a lock cavity 231 is opened in the lock core 230, a clamping hole 232 is opened on the inner bottom wall of the lock cavity 231, one end of the lock rod 220 passes through the clamping hole 232 to extend into the lock cavity 231, and a clamping head 221 is provided on the end of the lock rod 220 located in the lock cavity 231, the diameter of the clamping head 221 is larger than the diameter of the clamping hole 232, and the diameter of the clamping head 221 is smaller than the inner diameter of the lock cavity 231, and a groove 2211 is opened on the side surface of the clamping head 221 away from the lock rod 220, and the third elastic member 282 is located in the groove 2211.

[0065] It should be noted that when the clamp head 221 abuts against the inner bottom wall of the locking cavity 231, the third elastic member 282 will press the supporting sheet 281 and the supporting bearing 283. When the locking rod 220 descends, the clamp head 221 pushes the inner bottom wall of the locking cavity 231, so that the locking core 230 moves downward along the axial direction, thereby separating the clamping claws 250 from each other. When the locking rod 220 rises, under the elastic action of the third elastic member 282, the locking core 230 will move upward along the axial direction, so that the clamping claws 250 are close to each other. When the clamping claws 250 abut against the light-transmitting workpiece 20, as the locking rod 220 continues to move upward, the third elastic member 282 is compressed, and finally the locking rod 220 approaches or even abuts against the top holding piece 281. At this time, the clamping claws 250 are completely locked and cannot be separated from each other even if the loading base 210 rotates, so that the clamping claws 250 can reliably clamp and fix the light-transmitting workpiece 20.

[0066] like Figure 8 , Fig.11 and Fig.12 As shown, in one embodiment, a positioning cone block 290 is also provided on the top of the locking core 230, and the top of the positioning cone block 290 has a conical portion 291. A positioning groove 23a is provided at the center position of the bottom surface of the bottom block 23 of the light-transmitting workpiece 20. When the locking core 230 drives each clamping claw 250 to clamp the bottom block 23, the conical portion 291 is inserted into the positioning groove 23a.

[0067] It should be noted that it is necessary to ensure that the light-transmitting workpiece 20 and the carrier 210 rotate coaxially so that the grinding assembly 300 can grind the raised top wall 21 and the cylindrical outer wall 22 of the light-transmitting workpiece 20, so the above-mentioned centering structure is set. Specifically, a positioning groove 23a is pre-processed at the center position of the bottom surface of the bottom block 23, and then the bottom block 23 is placed against the carrier 210. As the locking rod 220 rises, the locking core 230 is driven to rise. First, each locking claw 250 clamps the edge of the bottom block 23. Then, as the locking core 230 is pushed up by the locking rod 220 and continues to rise, the conical portion 291 is inserted into the positioning groove 23a. In this way, under the action of the conical portion 291, the light-transmitting workpiece 20, the positioning cone block 290, and the loading seat 210 are in a coaxial state. Finally, the locking rod 220 compresses the third elastic member 282 so that the locking core 230 is limited and locked. At this point, the light-transmitting workpiece 20 is coaxially fixed to the loading seat 210, and then the loading seat 210 can be driven to rotate by the rotating driving member 260.

[0068] like Figure 8As shown, in one embodiment, the carrier 200 also includes a guide cylinder 2100 and two linear bearings 2200. A locking plate 2300 is provided at one end of the guide cylinder 2100. The locking plate 2300 is used to be fixed on the bracket 400 so that the guide cylinder 2100 can penetrate into the loading seat 210. The two linear bearings 2200 are coaxially mounted on the inner wall and the outer wall of the guide cylinder 2100, and the linear bearing 2200 located on the inner side is adapted to be matched with the locking rod 220, and the linear bearing 2200 located on the outer side is adapted to be matched with the loading seat 210.

[0069] In this way, under the guiding action of the guide cylinder 2100 and the two linear bearings 2200 , the locking rod 220 can stably slide along the axial direction of the material carrier 210 .

[0070] like Figure 7 As shown, in one embodiment, a block 2400 is further provided on the bracket 400 , and the block 2400 is distributed adjacent to the locking rod 220 . An inclined surface 2410 is provided on the block 2400 , and the locking rod 220 slides along the inclined surface 2410 so that the locking rod 220 slides axially along the loading seat 210 .

[0071] It should be noted that in order to enable the locking rod 220 to stably maintain the state of pushing the locking core 230 so that each clamping claw 250 clamps the light-transmitting workpiece 20, a clamping block 2400 is provided. By rotating the locking rod 220, the locking rod 220 slides along the inclined surface 2410, and the locking rod 220 rises along the axial direction of the material carrier 210, and is finally clamped at the highest point of the inclined surface 2410. In one embodiment, a magnetic block is installed at the highest point of the inclined surface 2410, and the locking rod 220 is magnetically fixed by the magnetic block.

[0072] In one embodiment, a plane is formed on the side wall of the bottom block 23 , and the clamping claws 250 abut against the plane to clamp the light-transmitting workpiece 20 .

[0073] Furthermore, if Figure 1 As shown, in one embodiment, a dust hood 500 is further provided on the machine 100, the opening of the dust hood 500 is arranged toward the material carrier 200, and the dust hood 500 is used to communicate with a dust collector. In this way, the dust generated by grinding the light-transmitting workpiece 20 can be sucked away through the dust hood 500.

The installation / fixing / setting mentioned in the present invention, unless otherwise specifically defined, may be understood to include but not be limited to locking and fixing with screws / screws, and welding.
