Description

Technical Field

[0001] This invention relates to the technical field of rotary surface polishing, and in particular to a polishing device for translucent handicrafts. Background Technology

[0002] like Figure 13 The translucent workpiece 20 with a rotating outer wall shown is used to fit and be installed inside a metal base 30 to form a complete accessory. A colored concave pattern is machined into the inner bottom wall of the metal base 30. Because the surface of the translucent workpiece 20 is transparent and raised, the pattern on the inner bottom wall of the metal base 30 is more visually appealing. With the improvement of people's living standards, the market demand for such accessories is increasing.

[0003] To improve the quality of the translucent workpiece 20 and ensure its compatibility with the metal base shell 30, it is necessary to polish its rotating raised top wall 21 and cylindrical outer wall 22. Currently, due to a lack of equipment for simultaneously polishing these two intersecting rotating surfaces, they are almost always polished manually by workers. However, manual polishing requires periodic comparison of the translucent workpiece 20 with a standard mold, resulting in extremely low efficiency. Furthermore, since the raised top wall 21 and cylindrical outer wall 22 are polished separately, polishing one surface can easily damage the other. Therefore, to address these shortcomings, the translucent craft polishing equipment of this application is proposed. Summary of the Invention

DETAILED DESCRIPTION

[0037] In order to facilitate the understanding of the present application, the present application will be described in more detail below with reference to the relevant drawings. The preferred embodiments of the present application are shown in the drawings.

[0038] As Figures 1 to 6As shown, a light-transmitting handicraft polishing device 10 comprises a machine table 100, a carrier 200 and a polishing assembly 300. The carrier 200 is rotationally arranged on the machine table 100 and is used to fix and cyclically rotate a light-transmitting workpiece 20. The polishing assembly 300 comprises a downward 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 driving member 310 is arranged on the machine table 100, and the polishing seat 320 is arranged on an output shaft of the downward driving member 310. The downward driving member 310 is used to drive the polishing seat 320 to approach or move away from the carrier 200. The first polishing block 330 is arranged in the polishing seat 320 in an axial sliding manner. The bottom end of the first polishing block 330 is provided with a first polishing surface 3321 which is matched with a convex top wall 21. The first elastic member 340 is in abutment with the first polishing block 330 and the polishing seat 320 respectively. The first elastic member 340 is used to push the first polishing block 330 to extend from the bottom end of the polishing seat 320. The second polishing block 350 is arranged on the first polishing block 330 in a slanting sliding manner. One side of the second polishing block 350 is provided with a second polishing surface 3521. The second elastic member 360 is in abutment with the second polishing block 350 and the first polishing block 330 respectively. The second elastic member 360 is used to push the second polishing block 350 so that the second polishing block 350 is in abutment with the polishing seat 320. When the downward driving member 310 is used to drive the polishing seat 320 to approach the carrier 200, the first polishing surface 3321 is first in abutment with the convex top wall 21 of the light-transmitting workpiece 20, and the second polishing surface 3521 is second in abutment with the cylindrical outer wall 22 of the light-transmitting workpiece 20. When the downward driving member 310 is used to drive the polishing seat 320 to move away from the carrier 200, the second polishing surface 3521 is first away from the cylindrical outer wall 22 of the light-transmitting workpiece 20, and the first polishing surface 3321 is second away from the convex top wall 21 of the light-transmitting workpiece 20.

[0039] It needs to be explained that the transparent workpiece 20 is fixed by the carrier 200 and driven to rotate continuously, and the convex top wall 21 and the cylindrical outer wall 22 which are both rotating surface structures on the transparent workpiece 20 are polished by the polishing assembly 300. Specifically, the downward driving member 310 is used to drive the polishing seat 320 to approach or move away from the carrier 200, for example, the downward driving member 310 can use a mechanical hand in the prior art to drive the polishing seat 320 to move. In this application, it is given that the polishing seat 320 is driven to move by a combination of lead screw modules, a first lead screw module is installed on the machine table 100, and a second lead screw module is installed on the output shaft of the first lead screw module, wherein the first lead screw module is used to drive the second lead screw module to move linearly along the horizontal plane, and the polishing seat 320 is installed on the output shaft of the second lead screw module, and the second lead screw module is used to drive the polishing seat 320 to move reciprocatingly along the vertical direction. Further, the polishing seat 320 is fixedly installed on the output shaft of the second lead screw module by screws. In this way, the polishing seat 320 can approach or move away from the carrier 200 under the driving of the downward driving member 310. When the polishing seat 320 approaches the carrier 200, the transparent workpiece 20 is polished. Specifically, an inner cavity extending along the axial direction is formed in the polishing seat 320 in the axial direction, and the first polishing block 330 is slidingly installed in the inner cavity of the polishing seat 320, so that the first polishing block 330 can slide along the axial direction of the polishing seat 320. The two ends of the first elastic member 340 abut against the first polishing block 330 and the polishing seat 320 respectively, wherein the first elastic member 340 can be a spiral spring. Under the elastic pushing force of the first elastic member 340, the first polishing block 330 extends from the bottom end of the polishing seat 320, wherein a first polishing surface 3321 is arranged on the lower end surface of the first polishing block 330, and the shape of the first polishing surface 3321 is adapted to the shape of the convex top wall 21 of the transparent workpiece 20. Further, the second polishing block 350 is obliquely slidingly installed on the first polishing block 330, specifically, the sliding direction of the second polishing block 350 and the axial direction of the first polishing block 330 have a certain angle, for example, the angle is in the range of 20°-30°, further, the angle can be 26°. The second elastic member 360 abuts against the second polishing block 350 and the first polishing block 330 respectively, wherein the second elastic member 360 is also a spiral spring. Under the elastic pushing force of the second elastic member 360, the second polishing block 350 has a tendency to rise and abut against the polishing seat 320.

[0040] Thus, in the natural state, the first elastic member 340 pushes the first polishing block 330 to move downward relative to the polishing seat 320. The second elastic member 360 pushes the second polishing block 350 to move obliquely upward relative to the first polishing block 330, and finally abuts against the polishing seat 320. When the driving member 310 is pressed to drive the polishing seat 320 to approach the carrier 200, the carrier 200 is fixed and drives the transparent workpiece 20 to continuously rotate at this time. When the first polishing surface 3321 abuts against the convex top wall 21 of the transparent workpiece 20 for polishing, since the first polishing block 330 is limited, as the polishing seat 320 continues to descend, the first elastic member 340 is compressed, and the polishing seat 320 pushes the second polishing block 350 to slide obliquely relative to the first polishing block 330, so that the second polishing surface 3521 slides obliquely to approach and finally abut against the cylindrical outer wall 22 of the transparent workpiece 20. Since the transparent workpiece 20 is fixed on the carrier 200 and continuously rotated, the first polishing surface 3321 polishes the convex top wall 21 of the transparent workpiece 20, and the second polishing surface 3521 polishes the cylindrical outer wall 22 of the transparent workpiece 20, so that the two rotating surface structures connected to each other on the workpiece are polished at the same time, and the polishing efficiency and quality of the transparent workpiece 20 can be effectively improved compared with the manual polishing method in the prior art.

[0041] As shown in Figure 5 In an embodiment, the first polishing block 330 includes a sliding core 331 and a first polishing head 332, the sliding core 331 is arranged in the polishing seat 320 to slide along the axial direction, and the first polishing head 332 is detachably arranged at the bottom of the sliding core 331, and the first polishing surface 3321 is located on the first polishing head 332.

[0042] It should be noted that the first polishing surface 3321 for polishing the convex top wall 21 of the transparent workpiece 20 is different due to the different curve structures of the axial cross section of the convex top wall 21. In order to be applicable to polishing the convex top wall 21 of the transparent workpiece 20 with different sizes, and as the polishing time increases, the first polishing surface 3321 will be worn out, and in order to facilitate the replacement of parts, the first polishing block 330 is arranged in the structure of the sliding core 331 and the first polishing head 332. Specifically, the sliding core 331 is slidingly installed on the axis of the polishing seat 320, and the first polishing head 332 is detachably installed on the bottom end of the sliding core 331 by screws. For example, the sliding core 331 is slid into the inner cavity of the polishing seat 320, so that the sliding core 331 can slide relative to the polishing seat 320.

[0043] As shown in Figure 3As shown, in an embodiment, the first polishing block 330 further comprises a limiting post 333, which is arranged on an end of the sliding core 331 away from the first polishing head 332, and the limiting post 333 is arranged through the polishing seat 320 to protrude from the top of the polishing seat 320, and the first elastic member 340 is sleeved on the limiting post 333. In this way, the first elastic member 340 is sleeved on the limiting post 333, and the first elastic member 340 can reliably push the sliding core 331.

[0044] As shown in the figure, Figure 3 As shown, in an embodiment, the limiting post 333 is provided with a limiting block 334 on an end of the outer side of the polishing seat 320, and the limiting block 334 is used for clamping with the polishing seat 320.

[0045] It should be noted that, in order to avoid the sliding core 331 from sliding out of the inner cavity of the polishing seat 320, the limiting block 334 is arranged to clamp with the polishing seat 320. Specifically, the diameter of the limiting block 334 is greater than the inner diameter of the through hole of the polishing seat 320 through which the limiting post 333 passes, so that the sliding core 331 cannot slide out of the polishing seat 320.

[0046] As shown in the figure, Figure 3 As shown, in an embodiment, the polishing assembly 300 further comprises an adjusting rod 371 and a cross 372, a cross hole 3331 is axially arranged on the limiting post 333, the cross 372 is slidingly arranged in the cross hole 3331, an end of the first elastic member 340 close to the polishing seat 320 abuts on the cross 372, and the adjusting rod 371 is screwed in the limiting post 333 along the axial direction, and the adjusting rod 371 is rotationally connected with the cross 372.

[0047] It should be noted that the above structure is arranged 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 post 333, so that the cross 372 slides along the cross hole 3331, and when the first polishing block 330 does not contact the convex 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 between the cross 372 and the sliding core 331, the natural total length of the first elastic member 340 can be adjusted, and thus the pressure of the first polishing block 330 on the convex top wall 21 of the light-transmitting workpiece 20 during polishing can be adjusted, so that the convex top wall 21 of the light-transmitting workpiece 20 can be better polished.

[0048] As shown in the figure, Figure 3 As shown, in an embodiment, one of the outer side wall of the sliding core 331 and the inner side wall of the polishing 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 slidingly arranged 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 polishing seat 320, a guide portion 335 is arranged to slide in the guide groove 321 to achieve a guiding effect.

[0050] As shown in Figure 6 , in an embodiment, the second polishing block 350 includes a sliding block 351 and a second polishing head 352. The sliding block 351 is obliquely arranged on one side wall of the sliding core 331. The second polishing head 352 is detachably arranged on the sliding block 351. The second elastic member 360 is in abutment with the sliding block 351 and the sliding core 331, respectively.

[0051] It should be noted that since the second polishing surface 3521 will be worn out over time, in order to facilitate the replacement of parts, the second polishing block 350 is arranged to be assembled by the sliding block 351 and the second polishing head 352. A T-shaped groove is obliquely formed on the sliding core 331. A T-shaped rail is obliquely arranged on the sliding block 351. The T-shaped rail is adapted to slide in the T-shaped groove, so that the sliding block 351 can slide obliquely relative to the sliding core 331. The second polishing head 352 is detachably mounted on the sliding block 351 by screws. In this way, when the second polishing surface 3521 is worn out, the second polishing head 352 can be directly replaced.

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

[0053] As shown in Figure 1 , Figures 7 to 12 , in an embodiment, the material carrying member 200 includes a material carrying seat 210, a material locking rod 220, a material locking core 230, a plurality of oblique guide blocks 240, and a plurality of material clamping claws 250. The machine table 100 is provided with a bracket 400. The material carrying seat 210 is rotationally arranged on the bracket 400. Each material clamping claw 250 is arranged to slide along the radial direction on the material carrying seat 210. Each material clamping claw 250 is distributed at a circumferential equal angle. An oblique guide hole 251 is formed in each material clamping claw 250. The material locking core 230 is arranged to pass through the material carrying seat 210. Each oblique guide block 240 is obliquely and circumferentially arranged on the outer side wall of the material locking core 230. Each oblique guide block 240 is in sliding connection with each oblique guide hole 251 in a one-to-one correspondence. The material locking rod 220 is arranged to pass through the material carrying seat 210. The material locking rod 220 is used to bear stress to drive the material locking core 230 to slide, so that each material clamping claw 250 moves closer to or further away from each other.

[0054] It should be noted that the support 400 is mounted on the machine table 100 by screws, and the material carrier 210 is rotatably mounted on the support 400. Each clamping jaw 250 is slidably mounted on the material carrier 210 along the radial direction, for example, a plurality of T-shaped sliding grooves are formed in the radial direction of the material carrier 210, and each clamping jaw 250 is provided with a T-shaped sliding rail at one end, which is adapted to slide in the T-shaped sliding groove, so that each clamping jaw 250 can stably slide along the radial direction of the material carrier 210. Among them, each clamping jaw 250 is distributed at a constant angle along the circumference of the material carrier 210, and the end of each clamping jaw 250 away from the T-shaped sliding rail is higher than the top surface of the material carrier 210. Further, an inclined guide hole 251 is formed obliquely in the clamping jaw 250. The locking core 230 is slidably mounted in the shaft center of the material carrier 210 along the axial direction, and each inclined guide block 240 is fixed at a constant angle along the circumference on the outer side wall of the locking core 230, and each inclined guide block 240 respectively passes through each inclined guide hole 251. Further, one end of the locking rod 220 extends into the locking core 230 from the bottom of the material carrier 210, and the other end of the locking rod 220 is located below the material carrier 210. In this way, by applying axial thrust and tension to the locking rod 220, the locking core 230 can slide along the axial direction of the material carrier 210, so that each clamping jaw 250 can approach or move away from each other under the cooperation of the inclined guide block 240 and the inclined guide hole 251. When each clamping jaw 250 approaches each other, the light-transmitting workpiece 20 placed on the material carrier 210 can be clamped and fixed. When each clamping jaw 250 moves away from each other, the light-transmitting workpiece 20 can be removed from the material carrier 210. In this way, the light-transmitting workpiece 20 is fixed by the material carrier 200, and when the material carrier 200 is driven to rotate, the light-transmitting workpiece 20 can be driven to rotate, so that the convex top wall 21 and the cylindrical outer wall 22 in the rotating surface structure of the light-transmitting workpiece 20 are synchronously polished under the action of the polishing assembly 300.

[0055] As shown in the drawings, Figure 8 In an embodiment, the bottom of the light-transmitting workpiece 20 is provided with a bottom block 23, and the material carrier 200 fixes the bottom block 23 to reliably fix the light-transmitting workpiece 20.

[0056] It should be noted that since the convex 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, the light-transmitting workpiece 20 will reserve a bottom block 23 at the bottom as an auxiliary fixing structure. When the convex top wall 21 and the cylindrical outer wall 22 are polished, the bottom block 23 can be cut off.

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

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

[0059] As shown in Figure 8 one embodiment, a thin ring 272 is provided on the outer side wall of the carrier seat 210, and a pressure bearing 273 is provided on both sides of the thin ring 272. A clamping plate 274 is buckled on the support 400, and the clamping plate 274 clamps the thin ring 272 and the two pressure bearings 273 together with the support 400. For example, the pressure bearing 273 is a thrust ball bearing, which can bear axial force. Thus, when the polishing assembly 300 presses and polishes the transparent workpiece 20, the pressure bearing 273 can transmit the pressure borne by the carrier seat 210 to the support 400, so as to avoid the rotating bearing 271 from being damaged by axial pressure. Thus, the cooperation of the rotating bearing 271 and the pressure bearing 273 can stably drive the transparent workpiece 20 to rotate.

[0060] As shown in Figure 7 one embodiment, the carrier piece 200 further comprises a rotating driving member 260, which is arranged on the support 400, and the output shaft of the rotating driving member 260 is connected with the carrier seat 210.

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

[0062] As shown in Figure 8 , Figure 11 , Figure 12 one embodiment, the carrier piece 200 further comprises a top holding piece 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 locking rod 220, the other end of the third elastic member 282 is connected with the top holding piece 281, and the top holding bearing 283 abuts against the top holding piece 281 and the locking core 230, so that the locking core 230 rotates relative to the top holding piece 281 through the top holding bearing 283.

[0063] It should be noted that the locking lever 220 is used to apply a pushing force to the locking core 230, so that the locking core 230 slides along the axial direction of the material carrier 210, thereby making the clamping claws 250 close to or away from each other. Since the material carrier 210, the locking core 230, the inclined guide blocks 240 and the clamping claws 250 need to rotate as a whole to drive the transparent workpiece 20 to rotate, the locking lever 220 does not need to rotate. Therefore, in order to make the locking lever 220 stably apply an axial pushing force to the locking core 230 to ensure that the clamping claws 250 clamp the transparent workpiece 20, while making the locking lever 220 not follow the rotation, avoiding the contact and friction between the locking lever 220 and the locking core 230, the above structure is provided. Specifically, the locking core 230 is elastically connected with the locking lever 220 through the third elastic member 282, wherein a top holding piece 281 is arranged at one end of the third elastic member 282 away from the locking lever 220, and a top holding bearing 283 is installed between the top holding piece 281 and the locking core 230. Wherein, the top holding bearing 283 is also a thrust ball bearing, so that when the locking lever 220 is subjected to a pushing force, the third elastic member 282 is compressed, the third elastic member 282 pushes the top holding piece 281, and then pushes the locking core 230 through the top holding bearing 283. In this way, the locking core 230 and the top holding piece 281 are connected through the top holding bearing 283 to rotate.

[0064] As shown in Figure 8 , Figure 11 , Figure 12 In an embodiment, a locking cavity 231 is formed in the locking core 230, a clamping hole 232 is formed in the inner bottom wall of the locking cavity 231, one end of the locking lever 220 passes through the clamping hole 232 to extend into the locking cavity 231, and a clamping head 221 is arranged on the end of the locking lever 220 located in the locking cavity 231. The diameter of the clamping head 221 is greater than the diameter of the clamping hole 232, and the diameter of the clamping head 221 is less than the inner diameter of the locking cavity 231. A groove 2211 is formed on the side of the clamping head 221 away from the locking lever 220, and the third elastic member 282 is located in the groove 2211.

[0065] It should be noted that when the clamping head 221 abuts against the inner bottom wall of the locking cavity 231, the third elastic member 282 will compress the top holding piece 281 and the top holding bearing 283. When the locking rod 220 descends, the clamping head 221 will push the inner bottom wall of the locking cavity 231, so that the locking core 230 moves downward along the axial direction, thereby causing the clamping jaws 250 to separate from each other. When the locking rod 220 rises, the locking core 230 will move upward along the axial direction under the elastic action of the third elastic member 282, thereby causing the clamping jaws 250 to approach each other. When the clamping jaws 250 abut against the light-transmitting workpiece 20, with the continuous upward movement of the locking rod 220, the third elastic member 282 is compressed, and finally the locking rod 220 approaches or abuts against the top holding piece 281. At this time, the clamping jaws 250 are completely locked, and cannot separate from each other even if the carrier seat 210 rotates, so that the clamping jaws 250 can reliably clamp and fix the light-transmitting workpiece 20.

[0066] As shown in Figure 8 , Figure 11 and Figure 12 , in an embodiment, the top of the locking core 230 is further provided with a positioning taper block 290, the top of the positioning taper block 290 has a tapered portion 291, and the center position of the bottom surface of the bottom block 23 of the light-transmitting workpiece 20 is provided with a positioning groove 23a. When the locking core 230 drives the clamping jaws 250 to clamp the bottom block 23, the tapered portion 291 is inserted into the positioning groove 23a.

[0067] It should be noted that the light-transmitting workpiece 20 and the carrier seat 210 need to rotate on the same axis to enable the polishing assembly 300 to polish the convex top wall 21 and the cylindrical outer wall 22 of the light-transmitting workpiece 20, so the above-mentioned centering structure is provided. Specifically, the 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 in close contact with the carrier seat 210. With the upward movement of the locking rod 220, the locking core 230 is driven to rise. First, the clamping jaws 250 clamp the edge of the bottom block 23, and then the tapered portion 291 is inserted into the positioning groove 23a as the locking core 230 is continuously pushed upward by the locking rod 220. In this way, under the action of the tapered portion 291, the light-transmitting workpiece 20, the positioning taper block 290 and the carrier seat 210 are in the same coaxial state. Finally, the locking core 230 is locked by the compression of the third elastic member 282 by the locking rod 220, and the light-transmitting workpiece 20 is fixed together with the carrier seat 210 in the coaxial state, and then the carrier seat 210 is rotated by the rotary driving member 260.

[0068] As shown in Figure 8As shown, in one embodiment, the material carrier 200 further includes a guide cylinder 2100 and two linear bearings 2200. One end of the guide cylinder 2100 is provided with a locking plate 2300, which is used to fix it on the bracket 400 so that the guide cylinder 2100 can pass through the material carrier 210. The two linear bearings 2200 are coaxially fitted on the inner and outer side walls of the guide cylinder 2100. The linear bearing 2200 located on the inner side is adapted to be connected with the locking rod 220, and the linear bearing 2200 located on the outer side is adapted to be connected with the material carrier 210.

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

[0070] like Figure 7 As shown, in one embodiment, the bracket 400 is also provided with a locking block 2400, which is distributed adjacent to the locking rod 220. The locking block 2400 is provided with an inclined surface 2410, and the locking rod 220 slides along the inclined surface 2410 so that the locking rod 220 slides along the axial direction of the material carrier 210.

[0071] It should be noted that a locking block 2400 is provided to ensure that the locking rod 220 can stably push the locking core 230 so that the clamping claws 250 clamp the light-transmitting workpiece 20. By rotating the locking rod 220, it slides along the inclined plane 2410 and rises along the axial direction of the carrier 210, eventually being locked at the highest point of the inclined plane 2410. In one embodiment, a magnetic block is installed at the highest point of the inclined plane 2410 to magnetically fix the locking rod 220.

[0072] In one embodiment, a flat surface is provided on the side wall of the bottom block 23, and the clamping claw 250 abuts against the flat surface to clamp the light-transmitting workpiece 20.

[0073] Furthermore, such as Figure 1 As shown, in one embodiment, a dust suction hood 500 is also provided on the machine base 100. The opening of the dust suction hood 500 faces the material carrier 200, and the dust suction hood 500 is used to communicate with a vacuum cleaner. In this way, the dust generated during the grinding of the light-transmitting workpiece 20 can be sucked away by the dust suction hood 500.
