DETAILED DESCRIPTION

[0018] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1: See also Figure 1-Figure 3As shown, a precision machining table for coating watch dials includes a coating machine body 1, a crucible 2, an electron gun 3, a fixed plate 4 and a working plate 5. The crucible 2 and the electron gun 3 are arranged at the inner bottom end of the coating machine body 1. The target material in the crucible 2 is heated, and the evaporated target material is extended by the electron gun 3, so that the target material can float to the top position of the coating machine body 1. The fixed plate 4 and the working plate 5 are arranged at the inner top end of the coating machine body 1, and the working plate 5 is arranged below the fixed plate 4; an installation component 8 is arranged in the middle of the working plate 5 and the middle of the fixed plate 4, and the working plate 5 is inserted into the installation component 8 The end of the fixed disk 4 is connected to the working disk 5 through the mounting assembly 8. A flipping structure 6 is arranged between the working disk 5 and the fixed disk 4. The flipping structure 6 includes a stepping motor 61. The stepping motor 61 is arranged inside the fixed disk 4. A spur gear 1 62 is arranged at the output end of the stepping motor 61. The stepping motor 61 is installed on the surface of the fixed disk 4. The stepping motor 61 can drive the spur gear 1 62 to rotate. A bevel gear 1 63 is arranged on the lower surface of the fixed disk 4. A spur gear 2 64 is arranged on the upper surface of the bevel gear 1 63. A connecting sleeve 611 is arranged in the middle of the bevel gear 1 63. The connecting sleeve 611 The spur gear 1 62 is connected to the middle of the bevel gear 1 63, and the top of the connecting sleeve 611 is screwed with the fixed disk 4, the spur gear 1 62 is meshed with the spur gear 2 64, and the stepping motor 61 drives the spur gear 1 62 to rotate, so that the spur gear 1 62 and the spur gear 2 64 rotate. Since the spur gear 2 64 and the bevel gear 1 63 are manufactured as a whole, the bevel gear 1 63 and the spur gear 2 64 rotate synchronously. A plurality of fixing holes 1 68 are opened on the surface of the working disk 5, and a fixing ring 65 is arranged inside each fixing hole 1 68. A rotating shaft 610 is arranged between the fixing rings 65 on the same radius, and the two ends of the rotating shaft 610 are respectively The bevel gear 67 is welded in the middle of the rotating shaft 610, and the bevel gear 67 is meshed with the bevel gear 1 63. The fixed rings 65 inside each fixed hole 68 rotate synchronously. The bevel gear 1 63 drives each bevel gear 2 67 to rotate, so that the bevel gear 2 67 rotates synchronously with the rotating shaft 610, which can drive the fixed rings 65 at both ends of the rotating shaft 610 to rotate. The watch dial inside the fixed ring 65 can rotate with the fixed ring 65, and the watch dial can be rotated inside the coating machine body 1 without taking out the watch dial for manual rotation.

[0020] See also Figure 3-Figure 5As shown, the axis of the fixed disk 4, the axis of the working disk 5, and the axis of the bevel gear 1 63 coincide with each other, and each bevel gear 2 67 and the rotating shaft 610 are arranged in a circular array. The working disk 5 can rotate around its axis, and it can also ensure that the bevel gear 1 63 is in contact with each bevel gear 2 67. A reserved hole 69 is opened inside the working disk 5, and the rotating shaft 610 is rotatably connected to the reserved hole 69, and the axis of the reserved hole 69 and the axis of the rotating shaft 610 both pass through the center of the working disk 5. The reserved hole 69 is used to limit the position of the rotating shaft 610, and the rotating shaft 610 can rotate inside the reserved hole 69.

[0021] See also Figure 5-Figure 6 As shown, a circle of fixing grooves 66 are provided on the surface of the working disk 5, and the fixing grooves 66 are arranged in a circular array on the surface of the working disk 5. The position of the fixing grooves 66 is matched with the position of the bevel gear 2 67. The bevel gear 2 67 is first placed into the fixing grooves 66, and then the rotating shaft 610 is obliquely inserted into the reserved hole 69, and then the rotating shaft 610 and the bevel gear 2 67 are welded, so that the bevel gear 1 63 can rotate with the bevel gear 2 67.

[0022] See also Figure 3-Figure 6 As shown, the fixing ring 65 is located inside the fixing hole 68, and the diameter of the fixing ring 65 is smaller than the diameter of the fixing hole 68. The rotation axis of the fixing ring 65 is matched with the axis of the rotating shaft 610. When the rotating shaft 610 rotates, the fixing rings 65 at both ends of the rotating shaft 610 can be driven to rotate. The diameter of the fixing hole 68 is larger than the diameter of the fixing ring 65 to avoid interference between the fixing ring 65 and the fixing hole 68 when the fixing ring 65 rotates.

[0023] It should be noted that the working disk 5 is placed inside the coating machine body 1, and the working disk 5 is installed at the installation assembly 8 at the fixed disk 4. When the working disk 5 is installed, the bevel gear 1 63 is in contact with each bevel gear 2 67, and then the parameters of the coating machine body 1 are set, the target material in the crucible 2 is heated, so that the target material in the crucible 2 is evaporated, and the target material is shot to the lower surface of the working disk 5 through the electron gun 3, and the target material adheres to the watch dial at the fixed ring 65. When one of the surfaces of the watch dial is coated, the dial is turned over. Specifically, the stepper motor 61 is started to drive the spur gear 1 62 to rotate, the spur gear 1 62 and the spur gear 2 64 are driven, and the bevel gear 1 67 is driven. 3 is integrated with the spur gear 2 64, so that the bevel gear 1 63 and the spur gear 2 64 rotate synchronously, the bevel gear 1 63 drives each bevel gear 2 67 to rotate, the rotating shaft 610 rotates along with the bevel gear 2 67, and the fixing rings 65 at both ends of the rotating shaft 610 rotate, so that the watch dial located inside the fixing ring 65 rotates, and at this time, all the watch dials on the working disk 5 rotate synchronously, and the watch dial does not need to be taken out of the coating machine body 1 to turn over the dial. The synchronously rotating fixing ring 65 can control the coating time on both sides of the dial, and will not waste too much time on turning over the dial. When more dials are rotated, no dials will be left behind, ensuring that each dial can be turned over.

[0024] See also Figure 2 and Figure 7As shown, a circle of the fixing ring 65 is provided with a clamping structure 7, and the clamping structure 7 includes a fixing ring 1 71 and a fixing ring 2 72. The fixing ring 1 71 and the fixing ring 2 72 are assembled into a whole circle, and the inner walls of the fixing ring 1 71 and the fixing ring 2 72 are provided with a fixing hole 2 73. The contact points of the two ends of the fixing ring 1 71 and the fixing ring 2 72 are provided with a magnetic block 1 75 and a magnetic block 2 76. The magnetic block 1 75 and the magnetic block 2 76 are attracted to each other. The watch dial is placed between the fixing ring 1 71 and the fixing ring 2 72 of the fixing ring 65, and the fixing hole 2 73 can be used to clamp the watch dial, so that the dial is located between the fixing ring 1 71 and the fixing ring 2 72, and the magnetic block 1 75 and the magnetic block 2 76 are used to attract each other. The magnetic block 1 75 and the magnetic block 2 76 can prevent the fixing ring 1 71 and the fixing ring 2 72 from separating. The end of the rotating shaft 610 passes through the interior of the fixing ring 1 71, and the fixing ring 1 7 A matching groove 78 is provided on the inner wall of the first fixing hole 68, and a nut 77 is provided at the end of the rotating shaft 610 and located inside the matching groove 78. The nut 77 is threadedly connected with the end of the rotating shaft 610. When the end of the rotating shaft 610 is screwed into the nut 77, the nut 77 is restricted in the inside of the matching groove 78. A guide column 710 is welded on the inner wall of the fixing hole 68 and located in the middle of the fixing ring 2 72. A telescopic spring 79 is sleeved on the outer side of the guide column 710. The fixing ring 1 71 is inserted into the end of the rotating shaft 610, and the end of the fixing ring 1 71 is screwed with the nut 77, so that the two fixing rings 1 71 are fixed to the end of the rotating shaft 610. Therefore, the rotation of the rotating shaft 610 can drive the fixing ring 1 71 and the fixing ring 2 72 at both ends of the rotating shaft 610 to rotate synchronously. The fixing ring 1 71 and the fixing ring 2 72 can also be prevented from separating by pushing the fixing ring 2 72 by the telescopic spring 79, so that the installation or removal of the dial is relatively quick.

[0025] See also Figure 7-Figure 8 As shown, one end of the fixing ring 1 71 and one end of the fixing ring 2 72 are welded with a matching block 74, and the end of the fixing ring 1 71 and the end of the fixing ring 2 72 are engaged with each other through the matching block 74, and the shape of the matching block 74 is used to limit the separation of the fixing ring 1 71 and the fixing ring 2 72, and to avoid the fixing ring 1 71 and the fixing ring 2 72 from being staggered when the fixing ring 1 71 and the fixing ring 2 72 are rotated; the inner wall of the fixing hole 1 68 is provided with a guide hole adapted to the guide column 710, and the guide column 710 is rotatably connected to the guide hole of the fixing hole 1 68, and the fixing ring 2 72 moves along the axial direction of the rotating shaft 610. Moving the fixing ring 2 72 can place the dial inside the fixing hole 2 73, and the telescopic spring 79 pushes the fixing ring 2 72 to move, thereby the fixing ring 2 72 moves with the fixing ring 1 71.

[0026] It should be noted that the rotating shaft 610 can drive the fixing rings 1 71 at both ends to rotate. Since the fixing ring 1 71 and the fixing ring 2 72 are attracted to each other through the magnetic block 1 75 and the magnetic block 2 76, the fixing ring 1 71 and the fixing ring 2 72 can be separated, and the dial can be placed inside the fixing hole 2 73. The telescopic spring 79 pushes the fixing ring 2 72 to move toward the fixing ring 1 71, and the guide column 710 moves along the inside of the guide hole. The fixing ring 1 71 and the fixing ring 2 72 are attracted to each other by the magnetic block 1 75 and the magnetic block 2 76 are attracted to each other, so that the dial can be fixed inside the fixing hole 2 73 of the fixing ring 65, and the ends of the fixing rings are restricted by the matching blocks 74 at the ends of the fixing rings 1 71 and 2 72, so it is convenient to install the watch dial. After the working disk 5 is taken out from the coating machine body 1 at a later time, the dial can be moved along the direction of the guide column 710 by pushing the two sides of the dial with two fingers, and the coated dial can be taken out of the fixing ring 65, and the fixing ring 1 71 and the fixing ring 2 72 are closed together under the action of the telescopic spring 79.

[0027] See also Figure 2 , Fig. 9 and Fig.10 As shown, the mounting assembly 8 passes through the interior of the working disk 5, and the mounting assembly 8 includes a fixing column 81, which is fixed to the middle of the fixing disk 4, and the fixing column 81 is located at the axial position of the connecting sleeve 611. The bottom end of the fixing column 81 is integrally provided with a connecting column 82, and the connecting column 82 passes through the interior of the connecting sleeve 611 of the bevel gear 1 63. The side wall of the connecting column 82 is provided with a tapered thread 84, and the interior of the connecting column 82 is provided with a deformation groove 85. The deformation groove 85 is pressurized so that the gap of the deformation groove 85 becomes smaller, and the tapered thread 84 A threaded sleeve 83 is screwed onto the outside, and a matching hole 87 is opened in the middle of the working disk 5. The connecting column 82 passes through the inside of the matching hole 87. The end of the connecting column 82 is inserted into the inside of the matching hole 87. Then, the deeper the connecting column 82 is inserted, the deformation groove 85 can be squeezed and deformed, so that the connecting column 82 can pass through the inside of the working disk 5 until the top end of the connecting column 82 completely passes through the inside of the working disk 5. At this time, the tapered thread 84 of the connecting column 82 cooperates with the threaded sleeve 83, and the working disk 5 can be fixed at the connecting column 82.

[0028] See also Fig.10As shown, a threaded sleeve 86 is integrally provided in the middle of the fixing column 81 and on the upper surface of the working disk 5, the working disk 5 is located between the threaded sleeve 83 and the threaded sleeve 86, and the diameter of the matching hole 87 is between the bottom diameter of the connecting column 82 and the top diameter of the connecting column 82. Since the top diameter of the connecting column 82 is slightly larger than the inside of the matching hole 87, the working disk 5 can be initially placed at the top of the connecting column 82 when the top of the connecting column 82 passes through the inside of the working disk 5, and the deformation groove 85 that restores its shape can prevent the working disk 5 from detaching from the connecting column 82 just after being installed, and then the working disk 5 is fixed by the threaded sleeve 83.

[0029] It should be noted that when installing the working disk 5, the working disk 5 is first inserted into the end of the connecting column 82. Since the bottom diameter of the connecting column 82 is small, the top diameter of the connecting column 82 is large, and the top of the connecting column 82 has a deformation groove 85, when the working disk 5 is inserted into the top of the connecting column 82, the deformation groove 85 can be squeezed and deformed, so that the working disk 5 can be fixed to the top of the connecting column 82. At this time, the deformation groove 85 is restored to its original size, and the working disk 5 can be initially restricted to the top of the connecting column 82. Finally, the end of the connecting column 82 is screwed into the threaded sleeve 1 83 so that the working disk 5 can be fixed between the threaded sleeve 1 83 and the threaded sleeve 2 86 to prevent the threaded sleeve 1 83 from loosening, and the threaded sleeve 2 86 can position the working disk 5 to ensure that the bevel gear 2 67 on the edge of the working disk 5 corresponds to the original bevel gear 1 63, ensuring that the bevel gear 1 63 and the bevel gear 2 67 are accurately meshed in the later stage.
