Description

Technical Field

[0001] This utility model belongs to the field of wax setting machine technology, specifically relating to a multi-station rotary positioning platform for a wax setting machine. Background Technology

[0002] In the field of jewelry manufacturing, wax setting is a key technique that involves pre-drilling holes in a wax model, setting gemstones, and then using lost-wax casting to secure the gemstones. Among these techniques, the point-setting process is a core component, and its efficiency and precision directly impact the production cycle and quality of jewelry products.

[0003] Traditional wax-setting drilling equipment typically employs a single-station fixed processing mode, requiring manual clamping and adjustment of each product. The equipment can only process one product at a time, necessitating frequent manual loading and unloading, resulting in long processing cycles. This is especially problematic for mass production, where high labor costs and limited efficiency gains are significant. Furthermore, it cannot achieve simultaneous clamping and rotation switching across multiple stations, leading to long waiting times between processes and hindering continuous production. Traditional equipment usually only possesses a single rotation function, unable to achieve multi-dimensional motion coordination, making it difficult to process complex drilling trajectories (such as ring-shaped or spiral-shaped gemstone holes).

[0004] In view of this, a multi-station rotary positioning platform for wax inlay machines with multi-station synchronous clamping, precise rotary positioning, multi-dimensional motion coordination and efficient heat dissipation is proposed to solve the above problems. Utility Model Content

[0005] The present invention aims to solve the technical problems of low single-station processing efficiency, reliance on manual adjustment for positioning accuracy, easy deviation of drilling position due to unstable transmission, single function of equipment, inability to meet the processing needs of complex trajectories, and impact on continuous production capacity in the above-mentioned prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-station rotary positioning platform for a wax setting machine includes:

[0008] A horizontal plate, on which positioning fixtures for clamping and positioning the product to be drilled are arranged at equal intervals;

[0009] A drive unit is used to drive the horizontal plate to rotate;

[0010] The positioning fixture includes a positioning shaft that is fixedly connected to the axle on the large pulley and is inserted and positioned to cooperate with the product to be drilled; a bearing seat A that is rotatably connected to the axle; a clamping rod that clamps and positions the product to be drilled on the positioning shaft and is rotatably connected to the bearing seat B; and a guide rail that is fixed on a horizontal plate and slides with the bearing seat B. The bearing seat B is pulled by a spring, causing the clamping rod to move towards the positioning shaft, and the clamping rod and the positioning shaft cooperate to clamp and fix the product to be drilled.

[0011] Preferably, the drive device includes a geared motor, two bearing seats C rotatably connected to rotating shafts, and two L-shaped rotating blocks fixedly connected to the rotating shafts on the two bearing seats C and connected to both ends of the horizontal plate.

[0012] A geared motor drives one of the rotating shafts to rotate, which in turn causes the horizontal plate to rotate.

[0013] Preferably, the two bearing housings C are respectively installed and fixed on the body of the wax inlay machine, and the geared motor is also installed and fixed on the body.

[0014] Preferably, bearing housing A is fixedly mounted on the mounting box, which is fixedly mounted on a horizontal plate. The large pulley extends into the mounting box and is connected to the small pulley via a transmission belt. Several servo motors are arranged at equal intervals inside the mounting box, and the output shaft of the servo motor is connected to the input shaft of the small pulley.

[0015] Preferably, a horizontal rod is provided on one side of the bearing housing B, and a vertical rod is provided on the top of the horizontal plate and on the side close to the bearing housing A, with the two ends of the spring connected to the horizontal rod and the vertical rod respectively.

[0016] Preferably, the mounting box is equipped with heat dissipation holes, and a cooling fan is installed inside the heat dissipation holes.

[0017] Compared with the prior art, the technical effects and advantages of this utility model are:

[0018] (1) The positioning fixtures evenly arranged on the horizontal plate of the multi-station rotary positioning platform of the wax setting machine can simultaneously clamp multiple products to be drilled. The horizontal plate is driven to rotate by the drive device, realizing sequential processing of multiple stations, avoiding the time waste of intermittent production at a single station, and is suitable for mass production. The rotation of the horizontal plate and the rotation of the products at each station (drilling trajectory processing) can be synchronized, without waiting for a single station to complete, shortening the overall processing cycle.

[0019] (2) The geared motor drives the horizontal plate through a rotating shaft, and with the stable support of the bearing seat C, it ensures smooth rotation of the horizontal plate, avoids shaking, and ensures consistent positioning accuracy at each station. The L-shaped rotating block distributes the driving force evenly on both sides of the horizontal plate, preventing deformation or jamming due to unilateral force. The product is positioned axially by the positioning shaft and radially clamped by the clamping rod, forming a double positioning system to ensure no displacement during the drilling process and improve processing consistency. The guide rail constrains the movement direction of the clamping rod to prevent product skewing. The spring tension allows the clamping rod to automatically adapt to products of different sizes or slight shape differences, reducing the frequency of fixture replacement. The positioning shaft can be designed in various specifications (such as cylindrical or stepped), and with the adjustable clamping rod, it is suitable for various jewelry such as rings and pendants.

[0020] (3) When manually operating the clamping rod, only the spring resistance needs to be overcome, resulting in high clamping efficiency and reducing the need for workers to exert repeated force; multi-position drilling of the product's circumference can be completed in one go, reducing the number of manual flipping operations. Multi-station synchronous processing and precise program control reduce manual intervention, decrease reliance on skilled workers, and improve production efficiency while reducing labor costs.

[0025] 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.

[0026] The following combination Figures 1 to 3 This application will be described in further detail.

[0027] This application discloses a multi-station rotary positioning platform for a wax setting machine, including a horizontal plate 1 and a driving device. The driving device drives the horizontal plate 1 to rotate. Positioning fixtures 2 for clamping and positioning products to be drilled are arranged at equal intervals on the horizontal plate 1. The driving device includes a geared motor 3, two bearing seats C5 rotatably connected to rotating shafts 4, and two L-shaped rotating blocks 6 fixedly connected to the rotating shafts 4 on the two bearing seats C5 and connected to both ends of the horizontal plate 1. The geared motor 3 drives one of the rotating shafts 4 to rotate, thereby driving the horizontal plate 1 to rotate. The two bearing seats C5 are respectively mounted and fixed on the body of the wax setting machine, and the geared motor 3 is also mounted and fixed on the body.

[0028] The positioning fixtures 2, evenly arranged on the horizontal plate 1, can simultaneously clamp multiple products to be drilled. A drive device rotates the horizontal plate 1, enabling sequential processing at multiple stations and significantly improving production efficiency. The drive device, via a geared motor 3 and a rotating shaft 4, combined with the stable support of the bearing seat C, ensures smooth rotation of the horizontal plate 1, preventing wobbling and guaranteeing consistent positioning accuracy at each station. The bearing seat C and geared motor 3 are directly fixed to the machine body, providing strong structural rigidity, reducing energy loss during transmission, and making it suitable for long-term, high-frequency operation. Both ends of the horizontal plate 1 are connected to the rotating shaft 4 via L-shaped rotating blocks, ensuring even distribution of driving force on both sides of the horizontal plate 1, preventing deformation or jamming caused by unilateral force. The L-shaped structure can be directly fixed to the horizontal plate 1 and rotating shaft 4, simplifying the assembly process and facilitating later maintenance and component replacement.

[0029] The positioning fixture 2 includes a positioning shaft 22 fixedly connected to the axle on the large pulley 21 and used to position the product to be drilled; a bearing seat A23 rotatably connected to the axle; a clamping rod 25 clamping and positioning the product to be drilled on the positioning shaft 22 and rotatably connected to the bearing seat B24; and a guide rail 26 fixed on the horizontal plate 1 and slidably guided by the bearing seat B24. A horizontal rod 212 is provided on one side of the bearing seat B24, and a vertical rod 213 is provided on the top of the horizontal plate 1 and on the side near the bearing seat A23. The horizontal rod 212 and the vertical rod 213 are connected by a spring 27. The bearing seat B24 is pulled by the spring 27 and slid along the guide rail 26, causing the clamping rod 25 to move toward the positioning shaft 22. The clamping rod 25 and the positioning shaft 22 cooperate to clamp and fix the product to be drilled.

[0030] The bearing housing A23 is fixedly installed on the mounting box 28, which is fixedly installed on the horizontal plate 1. The large pulley 21 extends into the mounting box 28 and is connected to the small pulley 210 via the transmission belt 29. Several servo motors 211 are arranged at equal intervals inside the mounting box 28, and the output shaft of the servo motor 211 is connected to the input shaft of the small pulley 210.

[0031] The tension of spring 27 causes clamping rod 25 to move automatically towards positioning shaft 22, accommodating products of different sizes or slight shape differences to be drilled, thus improving the versatility of the fixture. The elastic force of spring 27 ensures a firm clamping, while manual operation of clamping rod 25 only requires overcoming the resistance of spring 27, resulting in high clamping efficiency and reduced labor intensity for workers. Bearing seat B slides along guide rail 26, ensuring precise movement of clamping rod 25, preventing product skewing during clamping, and improving positioning accuracy.

[0032] Servo motor 211 can precisely adjust the speed of small pulley 210, driving large pulley 21 and positioning shaft 22 to rotate via transmission belt 29, achieving precise control of product rotation speed and meeting the needs of different drilling processes (such as matching speed with drilling depth). Multiple servo motors 211 within the mounting box 28 drive the small pulleys 210 of corresponding workstations, enabling independent rotation of products at each workstation (e.g., when processing different patterns at different workstations, the speed or direction can be flexibly adjusted), improving the flexibility of the equipment. Belt drive has a buffering and shock-absorbing effect, is quieter than gear drive, and has low maintenance costs, making it suitable for precision machining scenarios.

[0033] The product is fixed to the positioning shaft 22 via a plug-in connection, and radially clamped with the clamping rod 25, forming dual axial and radial positioning to ensure no product displacement during drilling and improve processing consistency. The positioning shaft 22 can be designed in different specifications (such as cylindrical, stepped, etc.) according to the product shape, and with the adjustable clamping rod 25, it is suitable for clamping various jewelry such as rings and pendants.

[0034] The servo motor 211 drives the small pulley 210 to rotate. The small pulley 210 is driven by the transmission belt 29 and the large pulley 21, which in turn drives the positioning shaft 22, the clamping rod 25, and the product clamped and fixed on the positioning shaft 22 and the clamping rod 25 to rotate. The reduction motor 3 drives the rotating shaft 4 to rotate, which in turn drives the horizontal plate 1 to rotate, which in turn drives the positioning fixture 2 and the product to rotate. The rotation of the product, together with the spot drill bit on the wax setting machine, performs spot drilling on the product to achieve spot drilling of the product.

[0035] The geared motor 3 drives the horizontal plate 1 to rotate the entire product (station switching), while the servo motor 211 drives the product to rotate (spot drilling trajectory processing). Together, they enable complex spot drilling trajectories (such as circular and spiral drill positions), expanding the equipment's processing capabilities. During the rotation of the horizontal plate 1, the products at each station rotate synchronously, eliminating the need to wait for individual stations to complete processing, shortening the overall processing cycle, and making it suitable for mass production. The product's rotation allows the spot drill bit to perform spot drilling at any angle. Combined with the rotation of the horizontal plate 1 to switch stations, spot drilling at multiple circumferential positions on the product can be completed in one go, reducing the number of manual flipping operations. By programming the speed, direction, and start / stop sequence of the servo motor 211 and the geared motor 3, the spot drilling path can be flexibly adjusted (such as clockwise / counterclockwise spot drilling, skip-type spot drilling, etc.) to adapt to diverse design requirements.

[0036] The mounting box 28 is equipped with heat dissipation holes 215, and a cooling fan 214 is installed inside the heat dissipation holes 215. The servo motor 211 is prone to overheating during prolonged high-load operation. The heat dissipation holes 215 and the cooling fan 214 create air convection, quickly dissipating heat from inside the mounting box 28, preventing performance degradation or malfunction due to overheating, and extending the equipment's lifespan. Low-temperature environments reduce the risk of belt aging and deformation due to high temperatures, maintain stable belt tension, and ensure transmission accuracy and reliability.

[0037] This multi-station rotary positioning platform for wax setting machines achieves high efficiency, high precision, and high flexibility in jewelry diamond setting through modular design, precise transmission, flexible clamping, and efficient heat dissipation. It is especially suitable for large-scale production scenarios, which can significantly improve the processing efficiency and product quality of enterprises, and reduce labor costs and equipment maintenance costs.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
