Description

Technical Field

[0001] This utility model relates to the field of pearl and agate processing technology, specifically a drilling positioning mechanism for pearl and agate production. Background Technology

[0002] Pearls are an ancient organic gemstone, primarily produced by pearl oysters and other mollusks. They are calcium carbonate mineral beads formed through the endocrine processes of these molluscs, composed of numerous tiny aragonite crystals. Pearls come in a rich variety of types, shapes, and colors.

[0003] In the core processes of pearl processing, such as positioning, conveying, and drilling, existing pearl positioning and fixing mechanisms have revealed significant technical bottlenecks. They are unable to perform precise and stable fixing operations on pearls of different sizes and specifications. This technical limitation directly affects the overall efficiency of pearl processing. On the one hand, when the fixing force is insufficient, the pearl is prone to displacement deviation during processing, leading to quality defects such as drilling position deviation and surface scratches, and even causing pearl breakage and loss. On the other hand, if a uniform strong clamping force is used, it will cause irreversible indentations or damage to the pearl surface due to the inability to adapt to the differences in individual pearl sizes. In view of this, a drilling and positioning mechanism for pearl and agate production is proposed. Utility Model Content

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0011] Please see Figure 1-4 This utility model provides a new technical solution: a drilling positioning mechanism for pearl and agate production, including a workbench 1, and a bracket 2 fixedly installed on the upper surface of the workbench 1. The workbench 1 is equipped with a drilling positioning mechanism, which includes a drill 3, an electric guide rail 4, a moving block 5, a vertical plate 6, a disc 7, a slide 8, a worm gear 9, a knob 10, a worm wheel 11, a lead screw 12, a collar 13, a support rod 14, a moving plate 15, and a clamping plate 16.

[0012] Furthermore, the drill 3 is fixedly installed on the upper surface of the bracket 2, the electric guide rail 4 is fixedly installed on the upper surface of the workbench 1, and the moving block 5 is slidably sleeved on the outer surface of the electric guide rail 4.

[0013] Furthermore, the upright plate 6 is fixedly installed on the upper surface of the movable block 5, and the disc 7 is fixedly installed on the upper surface of the upright plate 6; Four grooves 8 are formed on the front surface of the disk 7.

[0014] Furthermore, the worm 9 is rotatably connected to the inner wall of the disk 7, and the rear end of the worm 9 extends through the outer surface of the disk 7. The knob 10 is fixedly installed at the rear end of the worm 9.

[0015] Furthermore, the worm gear 11 is meshed with the outer surface of the worm 9, and the lead screw 12 is fixedly sleeved on the inner surface of the worm gear 11, with the left end of the lead screw 12 penetrating through the left surface of the disk 7.

[0016] Furthermore, the collar 13 is threaded onto the outer surface of the lead screw 12, and eight support rods 14 are rotatably connected to the outer surface of the collar 13.

[0017] Furthermore, four movable plates 15 are rotatably connected to the ends of eight support rods 14 away from the collar 13, and four clamping plates 16 are respectively fixedly installed on the opposite sides of the four movable plates 15. The drilling and positioning mechanism for pearl and agate production places the pearl or agate to be drilled between four clamping plates 16. Rotating the knob 10 causes the worm gear 9, fixedly mounted on the front surface, to rotate. The worm gear 9 then rotates the worm wheel 11, which is meshed with the outer surface. The worm wheel 11 rotates the lead screw 12, fixedly sleeved on the inner surface. Simultaneously, the collar 13, threaded on the outer surface of the lead screw 12, moves continuously to the left through the threads on the outer surface of the lead screw 12. At the same time, the collar 13 drives the eight support rods 14, rotatably connected to the outer surface, to move to the left. As the eight support rods 14 move to the left, they gradually become horizontal. Four movable plates 15, located away from the collar 13, apply a pulling force to their opposite surfaces. The four movable plates 15 move towards their opposite surfaces within the inner walls of the four sliding grooves 8. The four movable plates 15 apply a pushing force to the four clamping plates 16, which are fixedly installed on their opposite surfaces. At this time, the four clamping plates 16 clamp the pearl agate. Then, by starting the electric guide rail 4, the electric guide rail 4 drives the movable block 5, which is slidably mounted on the outer surface, to move to the left. The movable block 5 drives the vertical plate 6, which is fixedly installed on the upper surface, to move to the left. At this time, the pearl agate fixed on the disc 7 gradually approaches the drill 3, and the drill 3 drills a hole in the pearl agate. This drilling and positioning mechanism for pearl and agate production uses a series of transmission components, such as a worm gear 9, a worm wheel 11, and a lead screw 12, to drive a collar 13 and a support rod 14. This, in turn, applies force to the moving plate 15 and the clamping plate 16, achieving precise clamping of the pearl and agate. This transmission method ensures that the four clamping plates 16 clamp the pearl and agate evenly and stably, preventing it from shaking or shifting during drilling. This ensures the accuracy of the drilling position and improves the processing precision of the product. This drilling and positioning mechanism for pearl and agate production only requires turning the knob 10 to clamp the pearl and agate, making it simple and convenient to operate and reducing the labor intensity and difficulty for operators. At the same time, the electric guide rail 4 drives the moving block 5 and the upright plate 6 to bring the pearl and agate closer to the drill bit, which can precisely control the movement speed and position of the pearl and agate. This allows for flexible adjustments according to different drilling requirements and adapts to drilling and processing of pearl and agate of various specifications and shapes.

[0018] Structural Description: Workbench 1: As the basic support platform for the entire mechanism, it is used to support and fix other components, providing a stable working surface for drilling and positioning operations of pearls and agates.

[0019] Support 2: Fixedly installed on the upper surface of workbench 1, its main function is to support drill 3 and place it in a suitable position for drilling pearls and agates placed on workbench 1.

[0020] Drilling tool 3: Fixedly mounted on the upper surface of bracket 2, it is the direct execution component for drilling holes in pearls and agates, and drills the required holes in the pearls and agates by a high-speed rotating drill bit.

[0021] Electric guide rail 4: Fixedly installed on the upper surface of the worktable 1, providing a sliding track for the moving block 5. The moving block 5 can be controlled to move on the guide rail by electric drive, thereby realizing the horizontal position adjustment of the components installed on the moving block 5 to meet the drilling requirements of different positions.

[0022] Moving block 5: It is slidably sleeved on the outer surface of the electric guide rail 4 and can move along the electric guide rail 4. Its upper surface is used to fix and install the upright plate 6, which drives the upright plate 6 and its related components to move together, so as to achieve precise adjustment of the drilling position.

[0023] Vertical plate 6: It is fixedly installed on the upper surface of the movable block 5, and plays a supporting and connecting role. It fixes the disc 7 and other components at a certain height, so that they are at a suitable distance from the pearls and agates on the workbench 1, which facilitates positioning and drilling operations.

[0024] Disc 7: Fixedly installed on the upper surface of the vertical plate 6, it is one of the important components of the drilling positioning mechanism. The four sliding grooves 8 on its front surface are used to cooperate with the movement of the moving plate 15. At the same time, the disc 7 is equipped with transmission components such as worm gear 9 and worm wheel 11 to realize the adjustment and positioning of the clamping plate 16.

[0025] Slide 8: It is formed on the front surface of the disc 7 to provide a moving track for the moving plate 15, so that the moving plate 15 can slide in the radial direction of the disc 7, thereby driving the clamping plate 16 to move closer to or away from the center of the disc, so as to clamp and position the pearl and agate.

[0026] Worm 9: Rotatably connected to the inner wall of disk 7, with its rear end extending through the outer surface of disk 7 and fixedly mounted with knob 10. By rotating knob 10, worm 9 is driven to rotate. Utilizing the transmission relationship between worm and worm wheel, the rotational motion is transmitted to worm wheel 11, thereby driving lead screw 12.

[0027] Knob 10: Fixedly installed at the rear end of the worm 9, allowing the operator to manually rotate the worm 9. By rotating the knob 10, the rotation angle of the worm 9 can be precisely controlled, thereby controlling the moving distance and clamping force of the clamping plate 16.

[0028] Worm wheel 11: It is meshed with the outer surface of the worm 9 and forms a worm gear transmission mechanism with the worm 9. When the worm 9 rotates, the worm wheel 11 rotates under the drive of the worm 9. Since the lead screw 12 is fixedly sleeved on the inner surface of the worm wheel 11, the rotation of the worm wheel 11 will drive the lead screw 12 to rotate together.

[0029] Lead screw 12: It is fixedly sleeved on the inner surface of worm gear 11, and its left end extends through the left surface of disk 7. When lead screw 12 rotates under the drive of worm gear 11, the collar 13 sleeved on the outer surface of lead screw 12 will move along the axial direction of lead screw 12, thereby driving the moving plate 15 and clamping plate 16 to adjust their positions through support rod 14.

[0030] Collar 13: Screwed on the outer surface of lead screw 12. As lead screw 12 rotates, collar 13 will move axially on lead screw 12. Eight support rods 14 are rotatably connected to its outer surface. By moving itself, it drives the support rods 14 to move, thereby pushing the moving plate 15 and clamping plate 16 to achieve the clamping or loosening action of pearls and agates.

[0031] Support rod 14: Rotatably connected to the outer surface of collar 13, there are eight of them. One end of support rod 14 is rotatably connected to collar 13, and the other end is rotatably connected to moving plate 15. When collar 13 moves on lead screw 12, support rod 14 will change angle with the movement of collar 13, thereby pushing moving plate 15 to slide in slide groove 8, realizing position adjustment of clamp 16.

[0032] Movable plate 15: Rotatably connected to the end of the eight support rods 14 away from the collar 13, and slides in the groove 8 of the disc 7. The movement of the movable plate 15 will drive the clamping plate 16 fixedly installed on its opposite surface to move together, thereby achieving the clamping and positioning of the pearl and agate.

[0033] Clamping plates 16: These are fixedly installed on the opposite sides of the four movable plates 15, and are used to directly clamp the pearls and agates. Driven by the movable plates 15, the four clamping plates 16 can simultaneously move towards or away from the center of the disc, achieving stable clamping and positioning of pearls and agates of different sizes and shapes. This ensures that the pearls and agates do not move during drilling, guaranteeing the accuracy and quality of the drilling. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
