Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a clamping fixture for processing gold jewelry. Background Technology

[0002] In the field of gold jewelry processing, traditional clamping fixtures mostly employ manual operation or simple mechanical structures. Manual clamping is not only cumbersome and inefficient, but also makes it difficult to precisely control the clamping force, easily leading to displacement or surface damage of the jewelry during processing, affecting both the quality of the jewelry and the precision of the processing. While some mechanical clamping devices can achieve automatic clamping, they suffer from problems such as complex structure, high cost, and narrow applicability, failing to meet the diverse processing needs of gold jewelry of different shapes and sizes. Utility Model Content

[0003] To address the above problems, this utility model provides a gold jewelry processing fixture.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0005] A gold jewelry processing fixture includes a base, on which a housing is fixedly mounted. A first clamping component and a second clamping component are disposed on the housing. A driving mechanism is disposed inside the housing. The driving mechanism connects the first clamping component and the second clamping component and can drive the first clamping component and the second clamping component to clamp the gold jewelry.

[0006] Preferably, the drive mechanism includes a motor fixedly mounted outside the housing, and a drive rod is fixedly mounted on the output end of the motor.

[0007] Preferably, the end of the drive rod extends into the interior of the housing and is fixedly mounted with a drive gear, and a slide rod and a screw rod are provided through the housing.

[0008] Preferably, a transmission gear is fixedly installed in the middle of the screw, and the transmission gear meshes with the drive gear.

[0009] Preferably, the first clamping assembly includes a first clamping rod slidably mounted on one end of a slide rod, a first nut being fixedly mounted inside the first clamping rod, and the first nut being helically driven and mounted on one end of a screw rod.

[0010] Preferably, the second clamping assembly includes a second clamping rod slidably mounted on the other end of the slide bar, a second nut being fixedly mounted inside the second clamping rod, and the second nut being helically driven and mounted on the other end of the screw.

[0011] Preferably, both the first clamping rod and the second clamping rod have grooves at their ends, and the two grooves can be adapted to clamp the gold jewelry.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. By using a motor-driven gear transmission and a screw and nut spiral transmission mechanism, the first and second clamping rods move synchronously in opposite directions. Compared with the traditional manual clamping method, the clamping force can be adjusted quickly and accurately, significantly improving processing efficiency. At the same time, the high-strength structural design ensures stable clamping under the action of external processing forces, preventing the jewelry from loosening.

[0014] 2. The fitting grooves and high-elasticity rubber cushioning and shock-absorbing layer at the end of the clamping rod can accurately position gold jewelry of different shapes, preventing displacement during processing and ensuring accuracy. It also prevents clamping force from damaging the surface of the jewelry, guaranteeing its quality and aesthetics. A high-strength alloy base and wear-resistant engineering plastic shell are used, balancing stability and lightweight design. High-precision gears, linear optical shafts, and trapezoidal threaded screws, among other transmission components, undergo special processing, resulting in high transmission efficiency, low friction coefficient, and strong wear resistance, extending the clamp's service life and reducing maintenance costs.

[0022] Reference Figs. 1-3 A gold jewelry processing fixture includes a base 1 as the basic support component. The base 1 is cast from a high-strength alloy material, possessing excellent compressive strength and stability, capable of withstanding various external forces during processing without deformation or displacement. A housing 2 is fixedly mounted on the base 1 using high-precision bolts. The housing 2 is made of engineering plastic material with moderate hardness and wear resistance, effectively protecting the internal structure and reducing the overall weight of the fixture, facilitating operation and handling. On the surface of the housing 2, a first clamping component and a second clamping component are carefully designed. These two components work together to achieve precise clamping of the gold jewelry. Simultaneously, a drive mechanism is concealed inside the housing 2. This mechanism, like the "heart" of the fixture, cleverly connects the first and second clamping components, providing power for the clamping action and driving the first and second clamping components to stably clamp the gold jewelry.

[0023] The drive mechanism, serving as the power source for the entire fixture, has a core component: a motor 3 fixedly mounted outside the housing 2. Motor 3 is a high-precision servo motor, possessing advantages such as stable speed, high torque, and fast response, enabling precise control of clamping force and speed to meet the processing needs of gold jewelry of different specifications. A drive rod is fixedly mounted to the output end of motor 3 via a high-strength coupling. This drive rod is made of high-strength stainless steel, exhibiting excellent torsional resistance to ensure that it will not twist or deform during power transmission.

[0024] The end of the drive rod extends into the interior of the housing 2, and a drive gear 8 is fixedly mounted at its end. The drive gear 8 is manufactured using high-precision gear machining technology, achieving high tooth profile accuracy and a transmission efficiency of over 98%. A slide rod 4 and a screw rod 7 are connected through the housing 2. The slide rod 4 uses a linear optical axis, with a surface precision-ground and hard chrome-plated, exhibiting an extremely low coefficient of friction to provide smooth guidance for the sliding of the first and second clamping components. The screw rod 7 uses a high-strength trapezoidal thread screw, which boasts high transmission efficiency and strong load-bearing capacity.

[0025] A transmission gear 9 is fixedly installed in the middle of the screw 7 via a key connection. The transmission gear 9 is also manufactured with high precision and meshes precisely with the drive gear 8. The module, pressure angle, and other parameters of the two are perfectly matched to ensure stable and efficient power transmission. When the motor 3 starts, the drive rod drives the drive gear 8 to rotate. The drive gear 8, through meshing with the transmission gear 9, transmits power to the screw 7, causing the screw 7 to start rotating.

[0026] The first clamping assembly mainly consists of a first clamping rod 5 slidably mounted on one end of the slide rod 4. The first clamping rod 5 is made of lightweight, high-strength aluminum alloy, ensuring sufficient strength while reducing its weight. Inside the first clamping rod 5, a first nut is fixedly installed using an inlay process. This first nut engages with the thread at one end of the screw rod 7, forming a helical transmission pair. When the screw rod 7 rotates, due to the guiding effect of the slide rod 4, the first clamping rod 5 can only slide along the axial direction of the slide rod 4, thereby achieving the clamping action on one side of the gold jewelry. To further improve the clamping effect, a buffer and shock-absorbing layer is provided at the end of the first clamping rod 5. This buffer and shock-absorbing layer is made of highly elastic rubber, which can effectively prevent damage to the surface of the gold jewelry during clamping.

[0027] The second clamping assembly is symmetrical in structure and complementary in function to the first clamping assembly. It mainly includes a second clamping rod 6 slidably mounted on the other end of the slide rod 4. The second clamping rod 6 is also made of lightweight, high-strength aluminum alloy, and a second nut is fixedly installed inside using an inlay process. The second nut engages with the thread on the other end of the screw rod 7, forming a helical transmission pair. When the screw rod 7 rotates, the second clamping rod 6 slides axially under the guidance of the slide rod 4, working together with the first clamping rod 5 to clamp the gold jewelry. The end of the second clamping rod 6 is also equipped with a buffer and shock-absorbing layer, and positioning grooves are provided on the buffer and shock-absorbing layers at both ends of the clamping rods. The shape and size of the two grooves are precisely designed to accommodate gold jewelry of different shapes and sizes. Through the cooperation of the grooves, the gold jewelry can be accurately positioned and clamped, ensuring that the gold jewelry will not shift or rotate during processing.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
