Description

Technical Field

[0001] This utility model relates to the field of cutting fixture technology, specifically a multi-angle waterjet cutting fixture for stainless steel jewelry processing. Background Technology

[0002] In the stainless steel jewelry processing industry, as consumers' demand for personalized and diversified jewelry continues to grow, higher requirements are being placed on the processing precision and the ability to create complex shapes. Waterjet cutting technology, with its advantages of non-contact processing, no heat deformation, and the ability to cut complex shapes, has gradually become one of the important methods in stainless steel jewelry processing. Compared with traditional laser cutting and mechanical cutting processes, waterjet cutting can avoid the oxidation and discoloration of jewelry surfaces caused by high temperatures, while also enabling the processing of thin-walled and hollowed-out structures, meeting the quality requirements of high-end stainless steel jewelry.

[0003] Existing stainless steel jewelry waterjet cutting fixtures require disassembly and re-fixing after fixing the object to another angle, which is cumbersome. Furthermore, the workpiece fixing method is limited; traditional fixtures typically use rigid clamping structures, which are difficult to adapt to stainless steel jewelry of different shapes and sizes. For irregularly shaped jewelry, uneven localized force can easily occur during fixing, leading to surface damage or insecure clamping, causing displacement under the impact of the waterjet and affecting the cutting effect. Therefore, this utility model provides a multi-angle waterjet cutting fixture for stainless steel jewelry processing. Utility Model Content

Furthermore, the fixtures have a limited range of workpiece fixing methods; traditional fixtures typically use rigid clamping structures, which are difficult to adapt to stainless steel jewelry of different shapes and sizes. For irregularly shaped jewelry, uneven localized force can easily occur during fixing, leading to surface damage or insecure clamping, resulting in displacement under the impact of the waterjet and affecting the cutting effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-angle waterjet cutting fixture for stainless steel jewelry processing, comprising a support frame, wherein a clamping mechanism for stainless steel jewelry processing is provided on the support frame, and the clamping mechanism includes:

The telescopic end of the second electric push rod is rotatably connected to the limiting plate via a rotating shaft. A rubber plate is fixed to the clamping surface of the limiting plate.

[0013] Beneficial effects

[0014] This utility model provides a multi-angle waterjet cutting fixture for stainless steel jewelry processing. Compared with the prior art, it has the following advantages:

[0015] Firstly, this utility model, through the cooperation of the support shaft, processing platform, fixing ring, threaded hole, locking bracket, and second bolt, allows operators to quickly and conveniently adjust the angle of the processing platform to meet the diverse multi-angle cutting needs of stainless steel jewelry. The structural design is simple and clear; the rotation and fixation of the support shaft can be achieved simply by loosening and tightening the second bolt. The operation process is simple and easy to understand. Then, the first electric push rod is activated, and the telescopic end of the first electric push rod drives the pressure plate downward until the pressure plate contacts the top of the jewelry and applies pressure, further pressing the jewelry onto the processing platform from the vertical direction, ensuring that the jewelry will not be damaged by the water jet during the cutting process. The impact force causes displacement or shaking, providing a stable processing foundation for waterjet cutting operations. The position of the clamping plate is adjusted by rotating the screw, and the adaptive clamping of the limiting plate is driven by the second electric push rod. It can adapt to stainless steel ornaments of different shapes and sizes. The four sets of clamping plates, together with the limiting plate and pressure plate, clamp the ornaments in three dimensions from the horizontal and vertical directions, which can effectively fix them. This reduces the time and cost of changing clamps to adapt to different ornaments, and improves the applicability and processing efficiency of the clamps. The rubber plate increases the friction with the ornaments, avoiding damage to the surface of the ornaments while ensuring that the ornaments will not be displaced during the cutting process.

[0016] Secondly, the drainage holes on the support body of this utility model correspond to the water tank body, allowing the debris, abrasive, and water generated during the cutting process to quickly fall into the water tank body. This prevents debris from accumulating on the surface of the support body, affecting the positioning accuracy of the stainless steel ornaments and the normal operation of the cutting process, thus ensuring the continuity and stability of the cutting operation. The detachable structure composed of the filter screen bracket, connecting block, and first bolt facilitates quick cleaning of impurities inside the water tank body by operators. Through simple loosening, pulling out, cleaning, inserting, and tightening operations, the debris and abrasive trapped on the filter screen bracket can be cleaned. The water tank body, in conjunction with the filter screen bracket, can perform preliminary filtration of the cutting water, and the trapped abrasive can also be recycled. The treated water and abrasive can be reused, achieving resource recycling to a certain extent. Attached Figure Description

[0022] 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.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a multi-angle waterjet cutting fixture for stainless steel jewelry processing, including a support frame 1, on which a fixture mechanism for stainless steel jewelry processing is provided, the fixture mechanism including:

[0024] The adjustment assembly includes a water tank body 2 fixed inside the support frame 1, a support body 3 fixed at the upper end of the water tank body 2, a filter screen bracket 201 slidably connected to the inner wall of the water tank body 2, a support shaft 301 rotatably connected through the center of the support body 3, a processing platform 302 fixed at the top end of the support shaft 301, and a locking assembly for fixing at the lower end of the support shaft 301.

[0025] The clamping assembly includes a processing platform 302 with four sets of sliding grooves 7 on its upper surface. The sliding grooves 7 are equipped with clamping plates 702 connected by threaded assemblies. The clamping plates 702 are equipped with limiting plates 902 connected by push assemblies at both ends. A first electric push rod 8 is fixed to the upper end of the clamping plate 702. A pressure plate 801 is fixed to the telescopic end of the first electric push rod 8.

[0026] In a preferred embodiment, the filter support 201 extends to a connecting block 202 fixed at one end of the outer side of the water tank body 2. First bolts 203 for fixing are provided on both sides of the connecting block 202. The interior of the support body 3 is evenly provided with drainage holes 6, which correspond vertically to the water tank body 2. When using this multi-angle waterjet cutting fixture for stainless steel jewelry processing, the stainless steel jewelry is first placed on the processing platform 302 on the support body 3 for positioning and clamping. Subsequently, the waterjet cutting equipment is started, and high-pressure water jets cut the stainless steel jewelry. During the cutting process, [the following occurs]. The debris, abrasive, and used water will fall together. Since the support body 3 has evenly spaced drainage holes 6, and these holes 6 are vertically aligned with the water tank body 2, the debris, abrasive, and water will fall directly into the water tank body 2 through the drainage holes 6. When it is necessary to clean the debris and abrasive inside the water tank body 2, the operator loosens the first bolt 203 to release the fixing restriction on the connecting block 202. Since the filter support 201 is slidably connected to the inner wall of the water tank body 2, the filter support 201 can be pulled out of the water tank body 2 by pulling the connecting block 202. The water tank body 2 serves as a filter, allowing for quick cleaning of debris and abrasive particles trapped on the filter screen bracket 201 after it is removed. Once cleaning is complete, the filter screen bracket 201 is slid back into the water tank body 2, and the first bolt 203 is tightened to secure the connecting block 202, putting the filter screen bracket 201 back into operation and completing the cleaning process. The drainage holes 6 on the support body 3 correspond to those in the water tank body 2, allowing debris, abrasive particles, and water generated during cutting to quickly fall into the water tank body 2, preventing debris from accumulating on the surface of the support body 3 and affecting the positioning accuracy and cutting operation of the stainless steel ornaments. The filter support 201, connecting block 202, and first bolt 203 form a detachable structure that allows operators to quickly clean impurities from the water tank body 2. By simply loosening, pulling out, cleaning, inserting, and tightening, the debris and abrasive trapped on the filter support 201 can be cleaned. The water tank body 2, in conjunction with the filter support 201, can perform preliminary filtration of the cutting water. The trapped abrasive can also be recycled. The treated water and abrasive can be reused, achieving resource recycling to a certain extent.

[0027] In a preferred embodiment, the locking assembly includes a fixing ring 4 fixed to the lower end of the support body 3. Threaded holes 401 are evenly distributed around the periphery of the fixing ring 4. A locking bracket 5 is fixed to the lower end of the support shaft 301. One end of the locking bracket 5 is provided with a second bolt 501 corresponding to the threaded hole 401. Before performing multi-angle waterjet cutting of stainless steel jewelry, the stainless steel jewelry is placed on the processing platform 302 and positioned and clamped. When the cutting angle of the jewelry needs to be adjusted, the operator loosens the second bolt 501. Since the second bolt 501 corresponds to the threaded hole 401 on the fixing ring 4, after loosening, the fixed constraint between the locking bracket 5 and the fixing ring 4 is released, allowing the support shaft 301 to rotate freely at the center of the support body 3. The operator can then manually rotate the processing platform 302. The second bolt 501 is tightened to rotate synchronously, adjusting the processing platform 302 to the required cutting angle. After the angle adjustment is completed, the second bolt 501 is tightened to re-screw into the threaded hole 401 of the fixing ring 4. The second bolt 501 secures the locking bracket 5, thus keeping the processing platform 302 at the target angle. Through the cooperation of the support shaft 301, processing platform 302, fixing ring 4, threaded hole 401, locking bracket 5, and second bolt 501, the operator can quickly and conveniently adjust the angle of the processing platform 302 to meet the diverse multi-angle cutting needs of stainless steel ornaments. The structural design is simple and clear. The rotation and fixation of the support shaft 301 can be achieved simply by loosening and tightening the second bolt 501. The operation process is simple and easy to understand.

[0028] In a preferred embodiment, the threaded assembly includes a screw 701 rotatably connected inside the slide groove 7, a clamping plate 702 slidably connected at the lower end of the slide groove 7, and a threaded connection between clamping plates 702. The pushing assembly includes a fixing plate 9 fixed to one side wall away from the clamping surface of the clamping plate 702, with second electric push rods 901 rotatably connected to both ends of the fixing plate 9 via rotating shafts. A limiting plate 902 is located on both sides of the clamping plate 702 and rotatably connected via rotating shafts. The telescopic end of the second electric push rod 901 is rotatably connected to the limiting plate 902 via a rotating shaft. A rubber plate 90 is fixed to the clamping surface of the limiting plate 902. 3. Place the stainless steel ornament on the processing platform 302. Based on the shape and size of the ornament, rotate the screw 701. Since the screw 701 is threadedly connected to the clamping plate 702, and the clamping plate 702 slides at its lower end within the slide groove 7, the rotation of the screw 701 causes the clamping plate 702 to move along the slide groove 7. Adjust the positions of the four sets of clamping plates 702 so that they initially surround the ornament, thus defining its position. After initial positioning, activate the second electric push rod 901. The telescopic end of the second electric push rod 901 pushes the limiting plate 902 to rotate around the side wall of the clamping plate 702 via a rotating shaft. As the measuring plates 902 extend, they gradually move closer to the jewelry, until the rubber plate 903 on the clamping surface of the measuring plates 902 fits tightly against the side of the jewelry, clamping and fixing the jewelry from the side to prevent it from moving horizontally. After the lateral clamping is completed, the first electric push rod 8 is activated. The telescopic end of the first electric push rod 8 drives the pressure plate 801 to move downward until the pressure plate 801 contacts the top of the jewelry and applies pressure, further pressing the jewelry onto the processing platform 302 from the vertical direction. This ensures that the jewelry will not shift or shake due to the water jet impact during the cutting process, providing a stable processing foundation for the water jet cutting operation. Rotating the screw 701 adjusts the position of the clamping plate 702, which, in conjunction with the second electric push rod 901, drives the self-adaptive clamping of the limiting plate 902. This allows for the adaptation of stainless steel jewelry of different shapes and sizes. The four sets of clamping plates 702, together with the limiting plate 902 and the pressure plate 801, provide three-dimensional clamping for the jewelry from both horizontal and vertical directions, achieving effective fixation. This reduces the time and cost associated with changing clamps to adapt to different jewelry, and improves the applicability and processing efficiency of the clamps. The rubber plate 903 increases the friction with the jewelry, preventing damage to the surface of the jewelry while ensuring that the jewelry does not shift during the cutting process.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0030] During operation, the stainless steel ornament is placed on the processing platform 302. Based on the shape and size of the ornament, the screw 701 is rotated. Since the screw 701 is threadedly connected to the clamping plate 702, and the clamping plate 702 slides at its lower end within the slide groove 7, the rotation of the screw 701 causes the clamping plate 702 to move along the slide groove 7. The positions of the four sets of clamping plates 702 are adjusted so that they initially surround the ornament, thus defining its position. After initial positioning, the second electric push rod 901 is activated. The telescopic end of the second electric push rod 901... The rotating shaft drives the limiting plate 902 to rotate around the side wall of the clamping plate 702. As the second electric push rod 901 extends, the limiting plates 902 on both sides gradually move closer to the jewelry. Finally, the rubber plate 903 of the clamping surface of the limiting plate 902 fits tightly against the side of the jewelry, clamping and fixing the jewelry from the side to prevent it from moving horizontally. After the lateral clamping is completed, the first electric push rod 8 is activated. The telescopic end of the first electric push rod 8 drives the pressure plate 801 to move downward until the pressure plate 801 contacts the top of the jewelry and applies pressure. The jewelry is further pressed vertically onto the processing platform 302 to ensure that it will not shift or shake due to the water jet impact during the cutting process. Before performing multi-angle water jet cutting of stainless steel jewelry, the stainless steel jewelry is placed on the processing platform 302 and positioned and clamped. When the cutting angle of the jewelry needs to be adjusted, the operator loosens the second bolt 501. Since the second bolt 501 is connected to the threaded hole 401 on the fixing ring 4, after loosening, the fixed constraint between the locking bracket 5 and the fixing ring 4 is released, and the support shaft 301 can rotate freely at the center of the support body 3. The operator can manually rotate the processing platform 302 to drive the support shaft 301 to rotate synchronously and adjust the processing platform 302 to the required cutting angle. After the angle is adjusted, the second bolt 501 is tightened to screw it back into the threaded hole 401 of the fixing ring 4. The second bolt 501 is used to fasten the locking bracket 5 to firmly fix the support shaft 301, thereby keeping the processing platform 302 at the target angle.

[0031] When using this multi-angle waterjet cutting fixture for stainless steel jewelry processing, the stainless steel jewelry is first placed on the processing platform 302 on the support body 3 for positioning and clamping. Then, the waterjet cutting equipment is started, and high-pressure water jets cut the stainless steel jewelry. During the cutting process, the generated debris, abrasive particles, and used water fall together. Because the support body 3 has evenly spaced drainage holes 6, and these holes 6 are vertically aligned with the water tank body 2, the debris, abrasive particles, and water will pass through... The leak hole 6 falls directly into the water tank body 2. When it is necessary to clean the debris and abrasive in the water tank body 2, the operator loosens the first bolt 203 to release the fixing restriction on the connecting block 202. Since the filter screen bracket 201 is slidably connected to the inner wall of the water tank body 2, the filter screen bracket 201 can be pulled out from the water tank body 2 by pulling the connecting block 202. The filter screen bracket 201 plays a filtering and intercepting role in the water tank body 2. After being pulled out, the debris and abrasive trapped on the filter screen bracket 201 can be cleaned quickly.
