Description

Technical Field

[0001] The invention relates to the technical field of object clamping, in particular to a clamping device for jewelry polishing. Background Art

[0002] Jewelry polishing is a step in jewelry processing. Common polishing tools include grinding wheels, sandpaper, grinding discs, etc. Different tools are suitable for different polishing stages and materials. When jewelry is polished, the jewelry needs to be fixed to ensure the effect of jewelry polishing.

[0003] Jewelry comes in various shapes, including regular shapes such as round, square, and oval, as well as various irregular shapes. Conventional fixing structures cannot adapt to the shapes of jewelry. When clamping jewelry of non-standard shapes, it is difficult to achieve a tight fit by simply applying pressure to the jewelry through the fixing structures on both sides. It is easy for the jewelry to be loosely fixed. During the polishing process, the jewelry may move, affecting the polishing accuracy and even causing damage to the jewelry. Summary of the invention

[0004] The object of the present invention is to provide a clamping device for jewelry polishing to solve the problems raised in the above background technology.

The elastic pressing blocks are subjected to reverse thrusts exerted by the jewelry, and the elastic pressing blocks shrink along the axial direction in the rotating sleeve. A driving motor is arranged on the top of the mounting seat, and the driving motor is connected to the rotating shaft through a transmission belt, and is used to apply a circumferential thrust to the rotating sleeve and the jewelry clamped by the electric push rod.

[0006] Preferably, a connecting sleeve is provided on the back of the elastic pressing block for support, and a plurality of assembly sleeves for mounting the connecting sleeves are fixedly installed in the rotating sleeve, and the connecting sleeves are axially retracted in the assembly sleeves; An inner fixing rod movably inserted in the connecting sleeve is fixedly mounted on the assembly sleeve, and a buffer spring is arranged between the inner fixing rod and the connecting sleeve.

[0007] Preferably, the buffer spring applies a tensile force and an elastic force along the axis to the connecting sleeve.

[0008] Preferably, an L-shaped connector is fixedly mounted on the rotating shaft, a plug-in connector is fixedly mounted on one of the L-shaped connectors, and the plug-in connector is movably plugged into the other L-shaped connector; A locking bolt is threadedly connected to the L-shaped connector, and the locking bolt is supported at a corresponding position on the surface of the plug-in connector.

[0009] Preferably, the rotating sleeve is coaxially arranged with the electric push rod, and the two rotating sleeves have the same adjustment direction.

[0010] Preferably, an auxiliary driving ring is fixedly installed on the outside of one of the rotating sleeves, auxiliary driving teeth are fixedly installed on the outer wall of the auxiliary driving ring, the auxiliary driving teeth are distributed in a circular array with the center of the auxiliary driving ring as the array center, and an anti-slip ring is fixedly installed on the side of the auxiliary driving ring.

[0011] Preferably, the anti-slip ring and the auxiliary driving ring are coaxially arranged, and the anti-slip ring is arranged on a side away from the rotating sleeve.

[0012] Preferably, a control seat is fixedly mounted on the piston rod of the electric push rod, a telescopic pressing plate is horizontally movably mounted in the control seat, a vertical adjustment plate is vertically movably plugged into the control seat, and the vertical adjustment plate and the telescopic pressing plate have a staggered connection portion; A circular preset hole is provided in the control seat, a circular seat is fixedly installed in the circular preset hole, an assembly spring is fixedly installed on the circular seat, and the assembly spring is fixedly installed on the inner wall of the telescopic pressure plate.

[0013] Preferably, a rotatable pressure rod is rotatably connected to the control seat, and the rotatable pressure rod is supported at a corresponding position on the top of the vertical adjustment plate to apply downward pressure to the top of the vertical adjustment plate.

[0014] Preferably, a side seat is provided on the top of the mounting seat, a telescopic rod is fixedly mounted on the top of the side seat, a U-shaped seat is fixedly mounted on the piston rod of the telescopic rod, and a U-shaped receiving seat is fixedly mounted on the top of the U-shaped seat.

[0015] Preferably, an elastic belt is fixedly installed in the U-shaped receiving seat through a fixing buckle, and a lifting groove is provided at the bottom of the U-shaped receiving seat.

[0016] Preferably, a guide rail is provided on the top of the mounting seat, a slag receiving groove is provided above the guide rail, and a guide rod located in the guide rail is provided at the bottom of the slag receiving groove; The rotating sleeve is located just above the slag receiving trough.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The jewelry to be processed is placed between the two rotating sleeves, and the irregular edges of the jewelry are in contact with the elastic pressure blocks. The deformation of multiple elastic pressure blocks and the contraction of the elastic pressure blocks adapt to the fixation of the jewelry ends to ensure the fixing effect of the jewelry ends. Multiple elastic pressure blocks can adapt to the fixation of the jewelry ends through deformation and contraction, and can also fit well to jewelry with irregular edges, ensuring that jewelry of different shapes can be stably fixed, expanding the scope of application of the device, improving the versatility of various jewelry processing, ensuring the stability of jewelry during processing, and reducing processing errors caused by loose fixation. Different adjustment methods are selected according to the rotation amplitude of the jewelry. When a large adjustment is required, the two L-shaped connectors are connected, and a rotating shaft rotates to drive the two electric push rods to rotate. When a small adjustment is required, the hand contacts the auxiliary push teeth and the auxiliary push ring to achieve a small rotation of the rotating sleeve. Different adjustment methods can be selected according to the rotation amplitude of the jewelry, reflecting the flexibility of the design. When making large adjustments, by connecting two L-shaped connectors and using the rotating shaft to drive the electric push rod to rotate, large angle adjustments can be achieved quickly and efficiently, meeting the large rotation requirements of jewelry under certain complex processing techniques.

[0018] 2. When the jewelry falls on the U-shaped receiving seat and then falls on the elastic band, the elastic band is deformed. The presence of the lifting groove provides space for the elastic band to deform, and then the piston rod of the telescopic rod drives the U-shaped seat and the U-shaped receiving seat to retract, so as to assist in the recovery of the jewelry. The jewelry first falls on the U-shaped receiving seat and then falls on the elastic band. The buffering effect of the elastic band can effectively reduce the impact force on the jewelry when it falls, and prevent the jewelry from being damaged or scratched due to direct collision with hard surfaces, thereby ensuring the integrity and quality of the jewelry. The presence of the lifting groove provides space for the deformation of the elastic band, so that the elastic band can play a buffering role more naturally and fully, avoiding the impact of the buffering effect due to insufficient deformation space of the elastic band, and further enhancing the protection of the jewelry.

[0033] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 13The present invention provides a technical solution: a clamping device for jewelry grinding and processing, comprising a mounting seat 1, and two side assembly seats 2 for auxiliary mounting of a rotating shaft 3 are arranged on the top of the mounting seat 1; The two rotating shafts 3 are both provided with electric push rods 4 on the near side, and the piston rod ends of the electric push rods 4 are rotatably connected with rotating sleeves 5, and the two rotating sleeves 5 move towards each other along the axial direction; The electric push rod 4 arranged near the two rotating shafts 3 plays a key role. When the electric push rod 4 is started, its piston rod extends or retracts. Since the end of the piston rod is rotatably connected to the rotating sleeve 5, this telescopic action pushes the rotating sleeve 5 to move closer or farther from each other along the axial direction. For example, when processing jewelry of different sizes, the electric push rod 4 can be used to adjust the distance between the two rotating sleeves 5 to adapt to the length of the jewelry, so as to prepare for the subsequent stable clamping of the jewelry. Through the flexible adjustment of the distance between the rotating sleeves 5 by the electric push rod 4, the device can adapt to jewelry of different lengths and sizes. Whether it is a small and exquisite earring gem or a larger pendant gem, a suitable clamping distance can be found, which greatly expands the scope of application of the device.

[0035] A plurality of groups of elastic pressing blocks 6 are arranged in the rotating sleeve 5. The elastic pressing blocks 6 are subjected to the reverse thrust exerted by the jewelry, and the elastic pressing blocks 6 shrink along the axial direction in the rotating sleeve 5. When the jewelry is placed between the two rotating sleeves 5, the jewelry will apply a reverse thrust to the elastic pressing block 6 in the rotating sleeve 5. Because the elastic pressing block 6 is elastic, it will shrink along the axial direction in the rotating sleeve 5 after receiving the thrust. This shrinkage can make the elastic pressing block 6 fit the irregular shape of the jewelry, so as to tightly wrap the jewelry, achieve a stable clamping of the jewelry, and ensure that the jewelry will not shake or move during the grinding process. Multiple groups of elastic pressing blocks 6 can shrink according to the reverse thrust applied by the jewelry, which enables the device to perfectly fit jewelry of various shapes, including jewelry with irregular surfaces or unique textures. For example, for jade with carved patterns on the surface, the elastic pressing block 6 can fill the gaps in the pattern to achieve tight fixation, avoid damage to the jewelry due to loose fixation during grinding, and ensure high precision of grinding processing. The elastic pressing block 6 fits the shape of the jewelry and provides a stable clamping force. During the jewelry grinding process, it can effectively resist the impact and friction of the grinding tool on the jewelry, prevent the jewelry from moving or shaking, and ensure the smooth progress of the grinding work, thereby improving the quality and efficiency of jewelry grinding processing.

[0036] A driving motor 7 is arranged on the top of the mounting seat 1 , and the driving motor 7 is connected to the rotating shaft 3 through a transmission belt 8 , so as to apply a circumferential thrust to the rotating sleeve 5 and the jewelry clamped by the electric push rod 4 .

[0037] A connecting sleeve 9 is provided on the back of the elastic pressing block 6 for support. A plurality of assembly sleeves 10 for mounting the connecting sleeves 9 are fixedly installed in the rotating sleeve 5. The connecting sleeves 9 are axially retracted in the assembly sleeves 10. An inner fixing rod 11 movably inserted in the connecting sleeve 9 is fixedly mounted on the assembly sleeve 10 , and a buffer spring 12 is arranged between the inner fixing rod 11 and the connecting sleeve 9 .

[0038] When the jewelry applies pressure to the elastic pressing block 6, the elastic pressing block 6 is forced to shrink into the rotating sleeve 5. At this time, the connecting sleeve 9 connected to the back of the elastic pressing block 6 will expand and contract axially in the assembly sleeve 10. The assembly sleeve 10 is fixed in the rotating sleeve 5, providing a guide and support basis for the expansion and contraction of the connecting sleeve 9. The internal fixing rod 11 is fixed on the assembly sleeve 10 and movably inserted in the connecting sleeve 9. The buffer spring 12 between the internal fixing rod 11 and the connecting sleeve 9 plays a key buffering role when the elastic pressing block 6 is stressed. When the elastic pressing block 6 is squeezed by the jewelry, the connecting sleeve 9 shrinks into the assembly sleeve 10, and the buffer spring 12 is compressed to absorb and buffer the impact force on the elastic pressing block 6; when the jewelry pressure is reduced, the buffer spring 12 recovers its deformation, pushing the connecting sleeve 9 and the elastic pressing block 6 to reset, ensuring that the elastic pressing block 6 can always fit the jewelry tightly.

[0039] The setting of the buffer spring 12 greatly enhances the buffering ability of the elastic pressure block 6 on the jewelry. During the jewelry polishing process, the vibration and impact force generated by the polishing tool are transmitted to the connecting sleeve 9 through the elastic pressure block 6. The buffer spring 12 can effectively weaken these vibrations and impacts, further protect the jewelry, and prevent cracks or other damage on the jewelry surface caused by rigid impact, which significantly improves the safety of jewelry processing. The reset effect of the buffer spring 12 enables the elastic pressure block 6 to always accurately fit the jewelry surface. Even if the jewelry has a slight displacement or posture change due to force during the polishing process, the elastic pressure block 6 can quickly restore close contact with the jewelry under the action of the buffer spring 12, ensuring stable clamping of the jewelry, which is conducive to maintaining high precision of polishing processing and ensuring that all parts of the jewelry can be polished evenly.

[0040] The buffer spring 12 applies a tensile force and an elastic force along the axis to the connecting sleeve 9 .

[0041] An L-shaped connector 13 is fixedly mounted on the rotating shaft 3, and a plug-in connector 14 is fixedly mounted on one of the L-shaped connectors 13, and the plug-in connector 14 is movably plugged into the other L-shaped connector 13; when the jewelry needs to be adjusted at a large angle, the plug-in connector 14 fixed on one L-shaped connector 13 can be movably plugged into the other L-shaped connector 13. Through this connection method, the two rotating shafts 3 can achieve mechanical linkage to a certain extent.

[0042] A locking bolt 15 is threadedly connected to the L-shaped connector 13 , and the locking bolt 15 is supported at a corresponding position on the surface of the plug-in connector 14 .

[0043] The rotating sleeve 5 and the electric push rod 4 are coaxially arranged, and the two rotating sleeves 5 have the same adjustment direction.

[0044] An auxiliary driving ring 16 is fixedly installed on the outside of one of the rotating sleeves 5, and auxiliary driving teeth 17 are fixedly installed on the outer wall of the auxiliary driving ring 16. The auxiliary driving teeth 17 are distributed in a ring array with the center of the auxiliary driving ring 16 as the array center, and an anti-slip ring 18 is fixedly installed on the side of the auxiliary driving ring 16.

[0045] Because the auxiliary driving ring 16 is fixedly mounted outside the rotating sleeve 5, when the auxiliary driving ring 16 rotates, the rotating sleeve 5 is driven to rotate synchronously. In addition, because the rotating sleeve 5 is equipped with elastic pressure blocks 6 and other structures for clamping jewelry, the angle of the clamped jewelry can be precisely adjusted in a small range, meeting the demand for fine processing angle control during jewelry polishing.

[0046] The anti-slip ring 18 fixedly installed on the side of the auxiliary driving ring 16 increases the friction between the hand and the auxiliary driving ring 16 when the operator manually operates the auxiliary driving ring 16. It prevents the hand and the auxiliary driving ring 16 from slipping due to sweating or uneven force during operation, ensures that the operator can apply force stably and accurately, and achieves effective adjustment of the rotating sleeve 5 and the jewelry angle. The design of the auxiliary driving ring 16 and the auxiliary driving teeth 17 provides a high-precision small-angle adjustment method for jewelry polishing. Compared with large-angle adjustment by electric push rods, this manual fine adjustment can meet the extremely stringent requirements for angle control in the fine polishing stage of jewelry.

[0047] The anti-skid ring 18 and the auxiliary driving ring 16 are coaxially arranged, and the anti-skid ring 18 is arranged on a side away from the rotating sleeve 5 .

[0048] A control seat 19 is fixedly installed on the piston rod of the electric push rod 4, and a telescopic pressure plate 20 is installed in the control seat 19 for horizontal movement. A vertical adjustment plate 21 is vertically movably inserted on the control seat 19, and the vertical adjustment plate 21 and the telescopic pressure plate 20 have a staggered connection part; because the vertical adjustment plate 21 and the telescopic pressure plate 20 have a staggered connection part, when the vertical adjustment plate 21 moves vertically on the control seat 19, its staggered structure will drive the telescopic pressure plate 20 to move horizontally in the control seat 19, and the telescopic pressure plate 20 can flexibly adjust its position according to the shape and polishing requirements of the jewelry, providing additional auxiliary fixing points for the jewelry, and for jewelry with irregular shapes or prone to shaking during polishing, the telescopic pressure plate 20 can accurately extend and resist the key parts of the jewelry, effectively preventing the jewelry from being displaced during polishing, improving the stability of the jewelry during polishing, and thereby improving the accuracy and quality of the polishing process.

[0049] A circular preset hole 1901 is opened in the control seat 19 , a circular seat 22 is fixedly installed in the circular preset hole 1901 , an assembly spring 23 is fixedly installed on the circular seat 22 , and the assembly spring 23 is fixedly installed on the inner wall of the telescopic pressure plate 20 .

[0050] A rotatable pressure rod 24 is rotatably connected to the control seat 19 . The rotatable pressure rod 24 is supported at a corresponding position on the top of the vertical adjustment plate 21 to apply downward pressure to the top of the vertical adjustment plate 21 .

[0051] A side seat 25 is provided on the top of the mounting seat 1 , a telescopic rod 26 is fixedly mounted on the top of the side seat 25 , a U-shaped seat 27 is fixedly mounted on the piston rod of the telescopic rod 26 , and a U-shaped receiving seat 28 is fixedly mounted on the top of the U-shaped seat 27 .

[0052] The edges of both sides of the top of the U-shaped receiving seat 28 are raised to form a groove for receiving objects to prevent the polished jewelry from falling off.

[0053] An elastic band 30 is fixedly installed in the U-shaped receiving seat 28 via a fixing buckle 29 , and a lifting groove 2801 is provided at the bottom of the U-shaped receiving seat 28 .

[0054] A guide rail 31 is disposed on the top of the mounting base 1, a slag receiving groove 32 is disposed above the guide rail 31, and a guide rod 33 located inside the guide rail 31 is disposed at the bottom of the slag receiving groove 32; The rotating sleeve 5 is located directly above the slag receiving groove 32 .

[0055] Working principle: The first step: the jewelry to be processed is placed between the two rotating sleeves 5, and the rotating sleeves 5 are pushed to move by the piston rod of the electric push rod 4. The two rotating sleeves 5 reach both sides of the jewelry, and the irregular edges of the jewelry contact the elastic pressing blocks 6. The elastic pressing blocks 6 are subjected to the pressure given by the jewelry, and the jewelry will move with the connecting sleeve 9. The connecting sleeve 9 moves in the assembly sleeve 10, and the connecting sleeve 9 also moves outside the inner fixing rod 11. When the connecting sleeve 9 moves, it will press the buffer spring 12, and the elastic force generated by the deformation of the buffer spring 12 is used to assist the resetting of the elastic pressing blocks 6. The deformation of multiple elastic pressing blocks 6 and the contraction of the elastic pressing blocks 6 are used to adapt to the fixation of the jewelry ends and ensure the fixation effect of the jewelry ends; Different adjustment methods are selected according to the rotation amplitude of the jewelry. When a large adjustment is required, the two L-shaped connectors 13 are connected, and the plug-in connector 14 on the L-shaped connector 13 is movably inserted into the other L-shaped connector 13, and then the inserted plug-in connector 14 is fixed by the locking bolt 15 to achieve mutual fixation between the two rotating shafts 3, thereby achieving synchronous adjustment of the two rotating shafts 3 to achieve synchronous rotation of the two electric push rods 4, and the transmission belt 8 is driven by the driving motor 7 to drive the transmission, and the transmission belt 8 drives the rotating shaft 3 to rotate, thereby driving the two electric push rods 4 to rotate, realizing the rotation of the jewelry, and the rotation of the jewelry can achieve engraving of jewelry at different angles.

[0056] When a small adjustment is required, the hand contacts the auxiliary pushing tooth 17 and the auxiliary pushing ring 16, thereby applying pressure to the auxiliary pushing ring 16 and the auxiliary pushing tooth 17 to pull the rotating sleeve 5 to rotate on the piston rod of the electric push rod 4. The small rotation of the jewelry is achieved by rotating the rotating sleeve 5. After the rotation of the jewelry is completed, the rotating jewelry needs to be fixed. By pressing the vertical adjustment plate 21, the vertical adjustment plate 21 applies pressure to the side wall of the telescopic pressure plate 20. The telescopic pressure plate 20 extends out from the control seat 19. When the telescopic pressure plate 20 extends out, it will pull the assembly spring 23 to deform. After the assembly spring 23 is deformed, a reverse elastic force is generated to assist the subsequent resetting of the telescopic pressure plate 20. After the telescopic pressure plate 20 extends out, it will apply pressure to the auxiliary pushing tooth 17, thereby achieving the fixation of the rotating sleeve 5 after rotation, and then the rotatable pressure rod 24 is rotated to fix the vertical adjustment plate 21, thereby achieving the fixation of the rotating sleeve 5 after rotation.

[0057] Step 2: After the jewelry is processed, it is necessary to restart the electric push rod 4 to allow the two rotating sleeves 5 to move in opposite directions. The two rotating sleeves 5 no longer clamp the jewelry, and the jewelry falls on the U-shaped receiving seat 28, and then falls on the elastic belt 30. The elastic belt 30 is deformed. The existence of the lifting groove 2801 provides space for the elastic belt 30 to deform, and then the piston rod of the telescopic rod 26 drives the U-shaped seat 27 and the U-shaped receiving seat 28 to retract, thereby assisting the recovery of the jewelry.

[0058] Step 3: The debris generated by the processing falls on the slag receiving groove 32, and the slag receiving groove 32 is pulled out. The guide rod 33 moves in the guide rail 31 to guide the movement of the slag receiving groove 32. After the slag receiving groove 32 is pulled out, the debris on the slag receiving groove 32 is recovered.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
