Description

Technical Field

[0002] A watch case is the outer layer of a watch, typically used to protect and decorate it. Watch cases come in a variety of shapes and materials, and can be designed to meet diverse needs. Currently, most watches on the market utilize ring-shaped cases. These are not only unique and aesthetically pleasing, but also lightweight and comfortable to wear. Furthermore, they offer high impact resistance, making them suitable for a wide range of wrist sizes and suitable for a wider range of wearers.

[0003] In the prior art, annular watch cases are mostly formed by drilling holes in grinding equipment. During processing, the staff places the un-drilled circular watch case on the workbench of the grinding equipment, and drills the watch case by rotating the grinding tool to make the circular watch case into a ring shape. However, during the grinding process of the watch case, the waste chips generated by the rotating drilling of the grinding tool will accumulate in the drill hole. If it is not cleaned in time, it will not only cause the reduction of the processing accuracy of the cutter head, but also damage the high-speed rotating cutter head, affecting the service life of the cutter head. In addition, grinding fluid is often used to spray and cool the cutter head during grinding, but the existing grinding equipment lacks a structure for recycling the grinding fluid, so that the grinding fluid after spraying is directly discharged, resulting in a lot of waste.

[0004] To this end, the present invention provides a natural stone mechanical watch case and processing equipment thereof. Summary of the Invention

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] like Figures 1-12As shown, a processing device for a natural stone mechanical watch case according to an embodiment of the present invention includes a grinding machine body 1, a collecting tank 2 is fixed in the inner cavity of the grinding machine body 1, a workbench 3 is fixed in the collecting tank 2, an XYZ-axis moving frame 4 is provided on one side of the collecting tank 2, the XYZ-axis moving frame 4 is fixed in the inner cavity of the grinding machine body 1, a moving seat 5 is slidably connected to the top of the XYZ-axis moving frame 4, a grinding mechanism 6 and an annular spraying member 7 are fixedly installed on the bottom end of the moving seat 5, the annular spraying member 7 is located on the outside of the grinding mechanism 6, a motor 8 is fixedly installed in the inner cavity of the workbench 3, and the motor The output end of the machine 8 is fixedly connected to the rotating shaft 19, and the rotating shaft 19 is sleeved with a gear 10, and the gear 10 is meshed with the gear 2 11, and the gear 2 11 is sleeved on the rotating shaft 12, and the top of the rotating shaft 2 12 is fixedly connected to the flushing component. The top of the workbench 3 is provided with a groove 33, and the bottom center of the groove 33 is fixedly connected with a boss 30, and the boss 30 is rotatably connected to the flushing component. The outer side of the boss 30 is sleeved with a top support member 34, and the bottom end of the rotating shaft 2 12 is rotatably connected to the circulation pipe 1 26 through a sealed bearing, and the other end of the circulation pipe 1 26 is fixedly connected to the water pump 27. The pump 27 is fixedly installed in the inner cavity of the workbench 3, and a circulation pipe 28 is fixedly connected to the water pump 27. The other end of the circulation pipe 28 extends straight into the collection tank 2 and is fixedly connected to the filter element 29. The rotating shaft 12 is a hollow rod. When working, the staff places the annular case 44 on the workbench 3, and controls the grinding mechanism 6 to grind and drill the annular case 44 through the XYZ axis moving frame 4. The grinding mechanism 6 can be sprayed by the annular spraying member 7, which can not only achieve the effect of cooling, but also wash the waste chips on the surface of the workbench 3. The grinding liquid is sprayed out of the annular spraying member 7 and collected by the collection tank 2. The water pump 27 cooperates with the circulation pipe 1 26, the circulation pipe 2 28 and the filter element 29 to suck the grinding liquid in the collection tank 2 into the rotating shaft 2 12, and then sprays it out through the flushing component at the top of the rotating shaft 2 12. Cooperating with the groove 33 and the top support 34 provided on the workbench 3, the waste chips generated during the grinding process can be flushed. Not only can the waste chips accumulated in the hole formed by grinding in the annular case 44 be flushed out, avoiding the accumulation of waste chips affecting the accuracy of the grinding head of the grinding mechanism 6 during rotating grinding, but the grinding liquid can also be recycled to flush the annular case 44 during the grinding process, thereby improving the utilization rate of the grinding liquid.

[0036] The groove 33 is bowl-shaped, and the top support member 34 includes a guide block, an arc rod and a connecting rod. A plurality of guide blocks are evenly arranged on the outside of the boss 30. The guide blocks are fixedly connected by arc rods, and the guide blocks and the boss 30 are fixedly connected by connecting rods. The cross-section of the guide block is wing-shaped. During operation, because the guide block is wing-shaped and matches the bowl-shaped design of the groove 33, the grinding fluid still has a high pressure after being sprayed out of the flushing assembly through the channel formed by the guide block and the groove 33, thereby ensuring the flushing speed of the grinding fluid and allowing the waste chips in the drill hole to be cleaned.

[0037] A rotating shaft 3 13 is provided in the inner cavity of the workbench 3, and the rotating shaft 3 13 is sleeved on the rotating shaft 2 12, and the rotating shaft 3 13 is connected to the rotating shaft 2 12 through a limit assembly, and a bevel gear 19 is sleeved on the rotating shaft 3 13, and four bevel gears 20 are meshed and connected on the bevel gear 19, and the bevel gear 20 is sleeved on one end of the threaded rod 21, and the other end of the threaded rod 21 is rotatably connected to the inner wall of the workbench 3, and a threaded sleeve 22 is threadedly connected to the threaded sleeve 22, and a support plate 23 is fixed to the bottom end of the threaded sleeve 22, and the other end of the support plate 23 extends to the outside of the workbench 3 and is fixed to the bottom end of the clamping plate 24, and a rubber plate 25 is fixed to the inner side of the clamping plate 24; when working, when the ring 14-shaped case is fixed, the electric The machine 8 cooperates with gear 1 10 and gear 2 11 to drive the rotating shaft 2 12 to rotate, and the rotating shaft 3 13 is rotated together with the rotating shaft 2 12 through the limit assembly. The bevel gear 1 19 on the rotating shaft 3 13 drives the four bevel gears 2 20 to rotate together, so that the threaded sleeve 22 drives the clamping plate 24 on the support plate 23 to clamp and fix the annular watch case 44. The rubber plate 25 provided on the inner side of the clamping plate 24 can not only enhance the clamping effect of the annular watch case 44, but also reduce the vibration of the annular watch case 44 generated by the grinding mechanism 6 during the grinding process. Because the annular watch case 44 is made of semi-precious stone material and is relatively brittle, the phenomenon of cracks in the annular watch case 44 due to vibration can be avoided by reducing the vibration. When the annular watch case 44 needs to be removed, the motor 8 can be reversed.

[0038] The limit assembly includes an electromagnet 16, a spring 17 and a permanent magnet 18. A card slot is symmetrically provided on the rotating shaft 2 12. Two fixed blocks 15 are symmetrically fixed to the outside of the rotating shaft 3 13. An electromagnet 16 is fixed in the inner cavity of the fixed block 15. Two through slots are symmetrically provided on the rotating shaft 3 13. A permanent magnet 18 is slidably connected in the through slot. A spring 17 is fixed between the electromagnet 16 and the permanent magnet 18. The permanent magnet 18 fits in the card slot. The rotating shaft 3 13 is rotatably connected to the fixing ring 14. The fixed ring 14 is fixedly connected to the inner cavity of the workbench 3; during operation, when the rotating shaft 3 13 needs to rotate, the electromagnet 16 is energized, so that an electromagnetic repulsive force is generated between the electromagnet 16 and the permanent magnet 18, and then the permanent magnet 18 slides into the slot on the rotating rotating shaft 2 12 to achieve locking, so that the rotating shaft 3 13 rotates together with the rotating shaft 2 12. When the lock needs to be released, the electromagnet 16 is powered off, and the permanent magnet 18 can slide back into the through slot through the pulling force of the spring 17, so that the rotating shaft 3 13 is separated from the rotating shaft 2 12 and no longer rotates.

[0039] The flushing assembly includes a rotating part 31 and a flushing pipe 32. The top end of the rotating shaft 12 is connected to the bottom end of the rotating part 31, and the rotating part 31 is rotatably connected to the boss 30. A plurality of flushing pipes 32 are evenly fixed to the top of the rotating part 31. One end of the flushing pipe 32 is connected to the inner cavity of the rotating part 31, and the other end of the flushing pipe 32 is located between the guide block and the boss 30, and the pipe mouth is vertically downward; during operation, when the grinding liquid in the circulation pipe 1 26 enters the rotating shaft 2 12, it enters the inner cavity of the rotating part 31 through the rotating shaft 2 12, and is then sprayed out from the plurality of flushing pipes 32. After passing through the channel formed by the guide block and the inner wall of the groove 33, the waste chips accumulated in the groove 33 are cleaned, so that the waste chips in the groove 33 are flushed into the collection tank 2, which is convenient for subsequent centralized cleaning.

[0040] A rubber ring 42 is fixed to the top end surface of the workbench 3, and a heat dissipation groove 43 is provided on the top of the rubber ring 42. The heat dissipation groove 43 is annular and wavy, and a plurality of water inlets are evenly provided on the rubber ring 42, and the water inlets are connected to the heat dissipation groove 43. During operation, the rubber ring 42 provided on the top of the workbench 3 can further reduce the vibration generated by the grinding mechanism 6 during the grinding process, and protect the annular case 44. Through the water inlet provided on the rubber ring 42, a part of the grinding liquid ejected through the channel formed by the guide block and the inner wall of the groove 33 enters the heat dissipation groove 43. The grinding liquid can flow at the bottom of the annular case 44 through the annular and wavy heat dissipation groove 43, thereby reducing the heat generated by the grinding mechanism 6 during the grinding process and transmitted to the annular case 44, and avoiding the internal structure of the annular case 44 being changed due to the heat generated by grinding, thereby preventing damage.

[0041] The outer sides of the two clamping plates 24 are fixedly connected with a protective cover 1 35, and the protective cover 2 37 is slidably connected inside the protective cover 1 35. The two protective covers 1 35 and the two protective covers 2 37 form a circular cover, and the tops of the protective covers 1 35 and the protective covers 2 37 are both inclined. During operation, the slidable protective cover 2 37 cooperates with the protective cover 1 35 to not only facilitate the staff to place the annular watch case 44, but also prevent the grinding fluid from spraying and splashing during grinding, making it convenient to collect and recycle the grinding fluid.

[0042] The protective cover 1 35 is symmetrically provided with two groups of positioning holes 1 40 and two groups of positioning holes 2 41. A limiting block 36 is slidably connected in the inner cavity of the protective cover 1 35. The limiting block 36 is fixedly connected to the protective cover 2 37. One side of the protective cover 2 37 extends to the outside of the protective cover 1 35. A sliding groove is provided at one end of the protective cover 2 37 close to the limiting block 36. A conical block 39 is slidably connected in the sliding groove. A spring 2 38 is fixedly connected between the conical block 39 and the inner wall of the sliding groove. The conical block 39 is adapted to both the positioning hole 1 40 and the positioning hole 2 41. During operation, when the annular watch case 44 needs to be taken in and put out, the protective cover 2 37 is slid inward so that the conical block 39 is When block 39 corresponds to positioning hole 1 40, the elastic force of spring 2 38 can pop out the conical block 39 and get stuck in positioning hole 1 40, thereby locking protective cover 1 35 and protective cover 2 37. When grinding is required, the protective cover 2 37 is slid outward so that the conical block 39 corresponds to positioning hole 2 41, and the elastic force of spring 2 38 can pop out the conical block 39 and get stuck in positioning hole 2 41, thereby locking protective cover 1 35 and protective cover 2 37 again. The protective cover 1 35 and protective cover 2 37 together form an inverted conical cylinder, which can block the grinding fluid during grinding, thereby avoiding the problem of the grinding fluid spraying and splashing everywhere.

[0043] The annular spraying member 7 is composed of an annular spraying seat and a spraying pipe. The bottom of the movable seat 5 is fixedly connected to the annular spraying seat. The annular spraying seat is externally connected to the liquid supply equipment through the liquid inlet pipe. The bottom end of the annular spraying seat is evenly fixed with multiple groups of spraying pipes, and the multiple groups of spraying pipes are claw-shaped and distributed on the outside of the grinding mechanism 6. During operation, the claw-shaped spraying pipe provided on the outside of the grinding mechanism 6 can not only cool the grinding head in the grinding mechanism 6, but also flush the waste chips on the surface of the support member 34, so that the waste chips enter the groove 33, which is convenient for subsequent flushing into the collection tank 2.

[0044] like Figure 13As shown, a natural stone mechanical watch case is processed using the above-mentioned natural stone mechanical watch case processing equipment, and the watch case includes an annular case 44, a top cover 45 and a bottom cover 47. The top of the annular case 44 is fixedly connected to the top cover 45, and the outer side of the top cover 45 is symmetrically fixed with two metal frames 46. The bottom of the annular case 44 is fixedly connected to the bottom cover 47, and the outer side of the bottom cover 47 is symmetrically fixed with two metal frames 48. The bottom end of the metal frame 46 is fixedly connected to the top end of the metal frame 48.

[0045] Working principle: the staff places the annular watch case 44 on the workbench 3, and controls the grinding mechanism 6 to grind and drill the annular watch case 44 through the XYZ axis moving frame 4. The grinding mechanism 6 can be sprayed through the annular spraying part 7, which can not only achieve the effect of cooling, but also flush the waste chips on the surface of the workbench 3. The grinding liquid is sprayed out in the annular spraying part 7 and then collected by the collecting tank 2. The grinding liquid in the collecting tank 2 can be sucked into the rotating shaft 2 12 through the water pump 27, the circulating pipe 1 26, the circulating pipe 2 28 and the filter 29, and then sprayed out through the flushing component at the top of the rotating shaft 2 12. In combination with the groove 33 and the top support 34 provided on the workbench 3, the waste chips generated in the grinding process can be flushed, which can not only achieve the effect of cooling, but also flush the waste chips on the surface of the workbench 3. The waste chips accumulated in the hole formed by grinding the annular case 44 can be flushed out, avoiding the accumulation of waste chips affecting the accuracy of the grinding head of the grinding mechanism 6 during rotational grinding, and the grinding fluid can be recycled to flush the annular case 44 during the grinding process, thereby improving the utilization rate of the grinding fluid. Because the guide block is wing-shaped and matched with the bowl-shaped design of the groove 33, the grinding fluid still has a large pressure after being sprayed out from the flushing component through the channel formed by the guide block and the groove 33, thereby ensuring the flushing speed of the grinding fluid, so that the waste chips in the drill hole can be cleaned. When the ring 14-shaped case is fixed, the motor 8 cooperates with the gear 1 10 and the gear 2 11 to drive the rotating shaft 2 12 to rotate, and the limiting component allows the rotating shaft 3 13 to rotate with the rotating shaft 2 12 rotates together, the bevel gear 19 on the rotating shaft 3 13 drives the four bevel gears 20 to rotate together, so that the threaded sleeve 22 drives the clamping plate 24 on the support plate 23 to clamp and fix the annular watch case 44. The rubber plate 25 provided on the inner side of the clamping plate 24 can not only strengthen the clamping effect of the annular watch case 44, but also reduce the vibration of the grinding mechanism 6 on the annular watch case 44 during the grinding process. Because the annular watch case 44 is composed of semi-precious stone material and is relatively brittle, the phenomenon of cracks in the annular watch case 44 due to vibration can be avoided by reducing the vibration. When the annular watch case 44 needs to be removed, the motor 8 can be reversed. When the rotating shaft 3 13 needs to be rotated, the electromagnet 16 is energized so that the electromagnet 16 and the permanent magnet 18 An electromagnetic repulsive force is generated between them, which causes the permanent magnet 18 to slide into the slot on the rotating shaft 2 12 to achieve locking, so that the shaft 3 13 rotates together with the shaft 2 12. When the lock needs to be released, the electromagnet 16 is powered off, and the permanent magnet 18 can slide back into the slot through the pulling force of the spring 17, so that the shaft 3 13 is separated from the shaft 2 12 and no longer rotates. When the grinding liquid in the circulation pipe 1 26 enters the shaft 2 12, it enters the inner cavity of the rotating part 31 through the shaft 2 12, and is then sprayed out from the multiple sets of flushing pipes 32. After passing through the channel formed by the guide block and the inner wall of the groove 33, the waste chips accumulated in the groove 33 are cleaned, so that the waste chips in the groove 33 are flushed into the collection tank 2, which is convenient for subsequent centralized cleaning.The rubber ring 42 provided on the top of the workbench 3 can further reduce the vibration generated by the grinding mechanism 6 during the grinding process, and protect the annular case 44. The water inlet provided on the rubber ring 42 allows a part of the grinding liquid sprayed out through the channel composed of the guide block and the inner wall of the groove 33 to enter the heat dissipation groove 43. The grinding liquid can flow at the bottom of the annular case 44 through the annular wavy heat dissipation groove 43, reducing the heat generated by the grinding mechanism 6 and conducted to the annular case 44 during the grinding process, avoiding the internal structure of the annular case 44 being changed due to the heat generated by grinding, and then being damaged. When the annular case 44 needs to be taken in and placed, the protective cover is slid inward. When the conical block 39 is aligned with the first positioning hole 40, the spring 38 can eject the conical block 39 and get stuck in the first positioning hole 40, thus locking the protective cover 1 35 and the second protective cover 37. When grinding is required, the second protective cover 37 is slid outward so that the conical block 39 is aligned with the second positioning hole 41. The spring 38 can eject the conical block 39 and get stuck in the second positioning hole 41, thus locking the protective cover 1 35 and the second protective cover 37 again. The protective cover 1 35 and the second protective cover 37 together form an inverted conical cylinder, which can block the grinding fluid during grinding and avoid the problem of the grinding fluid spraying and splashing.
