Description

Technical Field

[0001] This utility model relates to the field of jewelry processing technology, specifically to a jewelry adhesive positioning device. Background Technology

[0002] Jewelry refers to raw materials and semi-finished products of gemstones and metals, as well as wearable ornaments, decorative crafts, and art collectibles made from raw materials and semi-finished products of gemstones and metals.

[0003] In the jewelry manufacturing process, semi-finished gemstones or metals are glued to the end of a support rod. Then, the operator holds the support rod to process the semi-finished gemstones or metals, or a machine tool clamps the support rod to process the semi-finished gemstones or metals at the end of the support rod.

[0004] However, the existing bonding method involves manually bonding the semi-finished gemstones or metals directly to the end of the support rod. The operator holds the semi-finished gemstones or metals and aligns them with the support rod, resulting in poor consistency in the relative position between the semi-finished gemstones or metals and the end of the support rod. This leads to deviations in the shape and structure of the gemstones or metals after processing, affecting the yield rate of jewelry. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a jewelry adhesive positioning device, which can ensure that the relative position of each semi-finished gemstone or metal part is consistent with the support rod, thus ensuring the stability of subsequent gemstone or metal part processing and improving the yield of jewelry.

[0006] The technical solution adopted by this utility model to solve its technical problem is: A jewelry adhesive positioning device includes a base, a positioning plate, a lifting seat, and several support rods. The positioning plate is disposed on the base, and the base has two first guide posts, which are vertically arranged. The lifting seat has two first guide sleeves, which are respectively fitted onto the outer periphery of the two first guide posts. The positioning plate has several contoured positioning cavities, the outline of which is similar to the outer contour of a semi-finished gemstone or metal product. The lifting seat has several limiting holes, each corresponding to one of the contoured positioning cavities. The limiting holes are used to limit the outer periphery of the support rods, and the contoured positioning cavities are used to position the semi-finished gemstone or metal product.

[0007] As a further improvement to the above technical solution, the cross-section of the support rod is circular, a protruding post is provided on the outer periphery of the support rod, the limiting hole is a circular hole, and a limiting groove is formed on the inner wall of the limiting hole along the length direction, the limiting groove accommodating the movement of the protruding post.

[0008] As a further improvement to the above technical solution, there are two positioning plates, both of which are fixed to the base by the first bolt. The two positioning plates are arranged symmetrically along the line connecting the two first guide posts. Several contour grooves are provided on the opposite side of the two positioning plates, and the contour positioning cavity is formed between the two contour grooves. A U-shaped groove is provided on the side of the positioning plate away from the contour groove. The width of the U-shaped groove is greater than the diameter of the shank of the first bolt and smaller than the diameter of the head of the first bolt.

[0009] As a further improvement to the above technical solution, an anti-loosening washer is provided between the first bolt and the positioning plate.

[0010] As a further improvement to the above technical solution, the base includes a fixed block, two translation blocks located on both sides of the fixed block, a transmission assembly for driving the two translation blocks to move closer to or away from the fixed block, two first guide posts are disposed on the fixed block, and two positioning plates are respectively fixed on the two translation blocks.

[0011] As a further improvement to the above technical solution, the transmission assembly includes a screw and two nuts. One end of the screw is provided with an operating handle. The fixed block and the two translation blocks are each provided with a through hole for the screw to pass through. The two nuts are respectively fixed to the side of the translation block away from the fixed block. The screw has a positive thread section and a negative thread section. One nut is threaded to the positive thread section of the screw, and the other nut is threaded to the negative thread section of the screw. A gear is provided at the bottom of the fixed block, and a rack is provided at the bottom of the fixed block. The two racks are respectively located on the radial sides of the gear, and the gear meshes with the racks.

[0012] As a further improvement to the above technical solution, a number of second guide posts are fixedly provided on the fixed block, and a number of second guide sleeves are provided on both translation blocks, with the second guide sleeves slidably sleeved on the second guide posts.

[0013] As a further improvement to the above technical solution, a locking assembly is provided between the fixed block and the two translation blocks. The locking assembly includes an elongated slider and two second bolts. The elongated slider has a waist-shaped hole. The width of the waist-shaped hole is greater than the diameter of the shank of the second bolt and smaller than the diameter of the head of the second bolt. The shanks of the two second bolts pass through the waist-shaped hole and are threaded onto the two translation blocks respectively. The top of both the translation block and the fixed block has a guide groove, and the elongated slider is slidably connected in the guide groove.

[0014] As a further improvement to the above technical solution, the number of locking components is two, and the two locking components are respectively arranged symmetrically with the axis of the screw as the center.

[0015] As a further improvement to the above technical solution, the cross-section of the elongated slider is I-shaped, and the guide groove is an I-shaped groove.

[0016] The beneficial effects of this utility model are: 1. This utility model provides a jewelry adhesive positioning device. By setting several contour positioning cavities and several limiting holes, the contour positioning cavities can position the semi-finished products of gemstones or metals. Adhesive is applied to the bottom ends of several support rods. Then, the support rods are passed through the limiting holes respectively, so that the corresponding semi-finished products of gemstones or metals are bonded to the bottom ends of the support rods. The limiting holes can radially limit the support rods. After the adhesive dries, the support rods are removed. Thus, it is ensured that the relative position of each semi-finished product of gemstones or metals is consistent with that of the support rod, ensuring the stability of subsequent gemstone or metal processing and improving the yield rate of jewelry.

[0017] 2. This utility model provides a positioning device for jewelry adhesive. By setting up a transmission component, when processing semi-finished products of gemstones or metals of different sizes, simply turning the operating handle can drive the screw to rotate. The two nuts, due to their opposite thread directions, simultaneously move the translation blocks closer to or away from the fixed block. Therefore, only one handle needs to be turned to adjust the position of the two positioning plates simultaneously, greatly simplifying the operation steps and improving adjustment efficiency. Simultaneously, when the translation blocks move, the rack fixed at its bottom also moves accordingly. The movement of the rack drives the meshing gear to rotate, and the rack on the other side of the gear moves in the opposite direction. This ensures that the two translation blocks can synchronously move closer to or away from the fixed block at the center position, guaranteeing that the movement distance of the two translation blocks is consistent, ensuring the symmetry of the two positioning plates after adjustment, and improving the accuracy of positioning the semi-finished gemstones or metals.

Detailed Implementation

[0021] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0022] Reference Figures 1 to 5 This utility model provides a jewelry adhesive positioning device, including a base 100, a positioning plate 200, a lifting seat 300, and several support rods 400. The positioning plate 200 is disposed on the base 100, and the base 100 is provided with two first guide posts 110, which are vertically arranged. The lifting seat 300 is provided with two first guide sleeves 310, which are respectively sleeved on the outer periphery of the two first guide posts 110. The positioning plate 200 has several contoured positioning cavities, the contours of which are similar to the outer contours of the semi-finished gemstone or metal product 500. The lifting seat 300 has several limiting holes 320, which correspond one-to-one with the contoured positioning cavities. The limiting holes 320 are used to limit the outer periphery of the support rods 400, and the contoured positioning cavities are used to position the semi-finished gemstone or metal product 500.

[0023] In use, several semi-finished gemstones or metals 500 are first placed in several contour positioning cavities. The contour positioning cavities can position the semi-finished gemstones or metals 500. Then, glue is applied to the bottom ends of several support rods 400. Next, the support rods 400 are passed through several limiting holes 320, so that the corresponding semi-finished gemstones or metals 500 are bonded to the bottom ends of the support rods 400. The limiting holes 320 can radially limit the support rods 400. After the glue dries, the support rods 400 are removed. This ensures that the relative position of each semi-finished gemstone or metal 500 and the support rod 400 is consistent, ensuring the stability of subsequent gemstone or metal part processing and improving the yield rate of jewelry.

[0024] In some preferred embodiments, the support rod 400 has a circular cross-section, a protruding post 410 is provided on the outer periphery of the support rod 400, the limiting hole 320 is a circular hole, and the inner wall of the limiting hole 320 is provided with a limiting groove 330 along the length direction. The limiting groove 330 accommodates the protruding post 410 to move through. Specifically, one end of the protruding post 410 is welded to the outer periphery of the support rod 400.

[0025] Understandably, the circular cross-section of the support rod 400 is easy to process, and the protruding post 410 can be connected to the outer periphery of the support rod 400 by welding. When processing the limiting hole 320, a hole is first drilled on the lifting seat 300, and then the limiting groove 330 is processed. This process is simple, reduces manufacturing costs, and improves processing efficiency.

[0026] In some preferred embodiments, there are two positioning plates 200. Both positioning plates 200 are fixed to the base 100 by first bolts 220. The two positioning plates 200 are arranged symmetrically around the line connecting the two first guide posts 110. Each of the two positioning plates 200 has a plurality of contour grooves 210 on its opposite side, and a contour positioning cavity is formed between the two contour grooves 210. A U-shaped groove 230 is provided on the side of the positioning plate 200 away from the contour grooves 210. The width of the U-shaped groove 230 is greater than the diameter of the shank of the first bolt 220 and smaller than the diameter of the head of the first bolt 220.

[0027] Understandably, when processing semi-finished products 500 of gemstones or metals of different sizes, by loosening the first bolt 220, then moving the positioning plate 200 along the length of the U-shaped groove 230, and finally tightening the first bolt 220, the positioning plate 200 is fixed in another position on the base 100. This allows for the adaptation to semi-finished products 500 of gemstones or metals of different sizes, improving the flexibility of the fixture and reducing its cost.

[0028] Furthermore, an anti-loosening washer 240 is provided between the first bolt 220 and the positioning plate 200 to prevent the first bolt 220 from loosening and to improve the firmness of the connection of the positioning plate 200.

[0029] In some preferred embodiments, the base 100 includes a fixed block 120, two translation blocks 130 located on both sides of the fixed block 120, and a transmission assembly 140 for driving the two translation blocks 130 to move closer to or away from the fixed block 120. Two first guide posts 110 are disposed on the fixed block 120, and two positioning plates 200 are fixed on the two translation blocks 130 respectively.

[0030] Specifically, the transmission assembly 140 includes a screw 141 and two nuts 142. One end of the screw 141 is provided with an operating handle 143. The fixing block 120 and the two translation blocks 130 are all provided with through holes for accommodating the screw 141. The two nuts 142 are respectively fixed on the side of the translation block 130 away from the fixing block 120. The screw 141 has a positive tooth section and a negative tooth section. One nut 142 is threadedly connected to the positive tooth section of the screw 141, and the other nut 142 is threadedly connected to the negative tooth section of the screw 141. A gear 144 is provided at the bottom of the fixing block 120, and a rack 145 is provided at the bottom of the fixing block 120. The two racks 145 are respectively located on the radial sides of the gear 144, and the gear 144 meshes with the rack 145.

[0031] It is understandable that by turning the operating handle 143, the screw 141 can be rotated. The two nuts 142 will move the translation block 130 closer to or further away from the fixed block 120 because the threads are opposite. By turning one handle, the positions of the two positioning plates 200 can be adjusted at the same time, which greatly simplifies the operation steps and improves the adjustment efficiency.

[0032] Simultaneously, when the translation block 130 moves, the rack 145 fixed at its bottom also moves. The movement of the rack 145 will drive the meshing gear 144 to rotate, and the rack 145 on the other side of the gear 144 will move in the opposite direction. This ensures that the two translation blocks 130 can move closer to or further away from the fixed block 120 at the center position in sync, ensuring that the movement distance of the two translation blocks 130 is consistent, ensuring the symmetry of the two positioning plates 200 after adjustment, and improving the accuracy of gemstone positioning.

[0033] Furthermore, a number of second guide posts 121 are fixedly provided on the fixed block 120, and a number of second guide sleeves 131 are provided on both translation blocks 130. The second guide sleeves 131 are slidably sleeved on the second guide posts 121.

[0034] It is understandable that the sliding pair formed by the second guide post 121 and the second guide sleeve 131 can restrict the translation block 130 to only move in a straight line along the axial direction of the second guide post 121. This can prevent the translation block 130 from deviating, ensure that the movement trajectories of the two translation blocks 130 are relatively parallel, and improve the stability of the translation block 130 when it moves.

[0035] In some preferred embodiments, a locking assembly 150 is provided between the fixed block 120 and the two translation blocks 130. The locking assembly 150 includes an elongated slider 151 and two second bolts 152. The elongated slider 151 has a waist-shaped hole 153. The width of the waist-shaped hole 153 is greater than the diameter of the shank of the second bolt 152 and smaller than the diameter of the head of the second bolt 152. The shanks of the two second bolts 152 pass through the waist-shaped hole 153 and are threaded onto the two translation blocks 130 respectively. The tops of the translation blocks 130 and the fixed block 120 are provided with guide grooves 132. The elongated slider 151 is slidably connected in the guide grooves 132.

[0036] When it is necessary to adjust the position of the two translation blocks 130, the elongated slider 151 and the translation block 130 can slide relative to each other by loosening the second bolt 152. When the translation block 130 is translated to the set position, the elongated slider 151 can be pressed onto the translation block 130 by tightening the second bolt 152 to form a rigid lock, preventing the translation block 130 from shifting after the position is adjusted, and improving the stability of the fixture.

[0037] Furthermore, there are two locking components 150, which are symmetrically arranged with respect to the axis of the screw 141.

[0038] Understandably, the two second bolts 152 on the same translation block 130 can apply locking force symmetrically, so that the translation block 130 is subjected to uniform force, eliminating the eccentric deformation caused by unilateral locking, and further improving the stability of the fixture.

[0039] Specifically, the cross-section of the elongated slider 151 is I-shaped, and the guide groove 132 is an I-shaped groove, which can prevent the elongated slider 151 from disengaging from the I-shaped groove during the adjustment of the position of the translation block 130, and prevent the translation block 130 from wobbling slightly.

[0040] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
