Description

Technical Field

[0001] This invention relates to the field of workpiece fixture technology, specifically a highly adaptable, change-free fixture based on intelligent CNC machining. Background Technology

[0002] Intelligent CNC machining refers to a new manufacturing model that integrates advanced technologies such as artificial intelligence (AI), big data analysis, and digital twins on the basis of traditional computer numerical control (CNC) machining to achieve autonomous optimization, real-time monitoring, and predictive maintenance of the machining process. It not only continues the high precision and high efficiency of CNC, but also improves production flexibility and system adaptability through intelligent means. At present, intelligent CNC machining equipment is indispensable for gold jewelry engraving. It can accurately and finely engrave the surface of jewelry, which is more exquisite and more efficient than manual engraving.

[0003] Existing intelligent CNC machining equipment uses highly adaptable, non-replaceable fixtures to hold jewelry during engraving. These fixtures can hold jewelry of different shapes, eliminating the need for frequent fixture changes and improving product adaptability while simplifying operation. However, adjusting the angle of circular gold jewelry (such as bracelets) presents a challenge when engraving them. 1. Drive the clamping mechanism to release the circular gold jewelry, manually adjust the angle of the circular gold jewelry, and restart the clamping mechanism to continue clamping and fixing it. This will complete the angle adjustment and fixation. However, the circular gold jewelry needs to be completely released. When rotating and adjusting the circular gold jewelry, there is no support or clamp. Without effective support, the jewelry is prone to excessive adjustment due to external force or its own weight, which will affect the adjustment efficiency.

[0004] 2. Some clamping mechanisms are equipped with retractable balls at the end of the clamping rod. The operation is optimized by the ball retracting when clamping and popping out when releasing to assist in clamping. However, in actual application, the movement range of the clamping rod needs to be frequently fine-tuned. This can easily lead to the jewelry slipping off or being clamped too tightly and difficult to rotate. The operation is cumbersome and has a low fault tolerance.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing highly adaptable, change-free fixtures based on intelligent CNC machining. Summary of the Invention

[0006] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. Specifically, the present invention aims to provide a highly adaptable, replacement-free fixture based on intelligent CNC machining to solve the problem mentioned in the background art where frequent fine-tuning of the clamping rod movement is required when adjusting the angle of circular gold jewelry, which can easily lead to the jewelry slipping off or being clamped too tightly and difficult to rotate.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a highly adaptable, change-free fixture based on intelligent CNC machining, comprising a carving machine body with a carving chamber, a carving drill bit and a fixture base disposed inside the carving machine body, and further comprising: The clamping rods and fixing seats, filled with oil, are evenly and symmetrically arranged above the clamping seat to clamp circular gold jewelry. A multi-hole ball bearing is rolled at the end of the clamping rod to assist in clamping and adjusting circular gold jewelry; Connecting plates, symmetrically arranged on the fixture base, are filled with oil and used to install the fixing base; The protrusions are evenly distributed inside the clamping rod to adjust the fixed and movable state of the multi-hole ball bearings; The driving components are symmetrically arranged on the clamping base and are used to drive the movement of the clamping rods; The control component, located on the clamp base, is used to adjust the angle of the circular gold jewelry; The linkage component, mounted on the fixture base, is used to drive the adjustment component to adjust the fixed or rotating state of the multi-hole ball bearing.

[0008] Preferably, the driving component includes an electric push rod fixed to the inner wall of the clamp seat; A movable plate is fixedly connected to one end of the electric push rod; A clamping plate is fixedly connected to the top of the movable plate; The clamping plate is slidably sleeved with the clamping seat; The fixing seat is fixedly sleeved with the clamping plate; A first spring is fixedly connected to the inner wall of the fixed base; One end of the first spring is fixedly connected to the clamping rod; The clamping rod is slidably connected to the fixed base.

[0009] Preferably, a sealing block is slidably connected inside the clamping rod; The sealing block has an arc groove on one side, and the inner wall of the arc groove is uniformly provided with grooves. A second spring is fixedly connected to the inner wall of the groove; One end of the second spring is fixedly connected to the protrusion; The protrusion and the groove are slidably connected; One end of the protrusion is an arc surface.

[0010] Preferably, the control component includes a bearing embedded in the inner wall of the clamp seat; The inner ring of the bearing is uniformly and fixedly connected with connecting rods; An adjusting wheel is fixedly connected to one end of the connecting rod; A rotating block is fixedly connected to the other end of the connecting rod.

[0011] Preferably, the adjusting wheel has a circular ring structure; The top of the clamp base is provided with a through groove; The adjusting wheel extends through the slot to the outside of the clamp seat.

[0012] Preferably, a groove is provided on one side of the rotating block, and a third spring is fixedly connected to the inner wall of the groove; One end of the third spring is fixedly connected to a push block; A movable tube is fixedly connected to one side of the block; The moving tube is sleeved with the adjusting wheel.

[0013] Preferably, the linkage component includes an adjusting cylinder containing oil fixed inside the clamp seat; A fourth spring is fixedly connected to the inner wall of the adjusting cylinder; A sealing plate is fixedly connected to one end of the fourth spring; The inner wall of the adjusting cylinder is fixedly connected to a first flexible hose; One end of the first flexible tube is fixedly connected to a flexible connecting tube; Both ends of the flexible connector are fixedly connected to oil pipes; The oil pipe is fixedly connected to the connecting plate; A second flexible hose is uniformly fixedly connected to one side of the connecting plate; The second hose passes through the mounting base and extends into the interior of the clamping rod; The second hose is fixedly connected to the clamping rod.

[0014] Preferably, a push block is slidably connected inside the adjusting cylinder; A fifth spring is fixedly connected to the top of the push block; One end of the fifth spring is fixedly connected to the adjusting cylinder; A protruding rod is fixedly connected to the top of the push block.

[0015] Preferably, the top of the protruding rod extends to the outside of the adjusting cylinder; The protruding rod is slidably connected to the adjusting cylinder; The top of the protruding rod is an arc surface.

[0016] Preferably, one end of the adjusting cylinder extends into the interior of the moving tube.

[0017] Compared with the prior art, the beneficial effects of the present invention are: By pressing the button, the moving tube moves, squeezing the protruding rod and moving it into the adjusting cylinder, pushing the push block and sealing plate downwards. Because the sealing plate is sealed to the adjusting cylinder, the negative pressure generated by the downward movement draws the oil in the first hose into the adjusting cylinder, and then draws out some of the oil inside the clamping rod. Under the action of negative pressure, the sealing block drives the protruding block to disengage from the porous ball bearing, allowing it to rotate freely. At the same time, rotating the rotating block drives the adjusting wheel to rotate through the connecting rod. With the help of the high friction of the rubber material on the outer wall of the adjusting wheel, the jewelry is rotated, achieving flexible angle adjustment to meet different engraving needs. This device eliminates the need for frequent adjustment of the clamping rod when adjusting circular gold jewelry and also has auxiliary clamping capabilities. Compared with existing technologies, it has the advantages of improved engraving efficiency, tight fit of all components, stable operation, and simple operation.

[0018] By designing multiple small holes and setting several protrusions on the ball bearing, the ball bearing can be fixed when the protrusions are pushed into the holes on the outside of the ball bearing. When the protrusions are disengaged from the ball bearing, the ball bearing can rotate 360 ​​degrees. When the protrusions are inserted into the holes on the outside of the ball bearing, the ball bearing is fixed. Statistically, some protrusions will always be inserted into the holes of the multi-hole ball bearing. Therefore, the fixed and movable states of the multi-hole ball bearing can be adjusted according to the adjustment requirements, thereby improving the clamping effect of the device.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1 to 13 This invention provides a technical solution: a highly adaptable, change-free fixture based on intelligent CNC machining, comprising a carving machine body 1 with a carving chamber 6, a carving drill bit 2 and a fixture base 3 disposed inside the carving machine body 1, and further comprising: The clamping rod 46 and the fixing seat 44, which are filled with oil, are evenly and symmetrically arranged above the clamping seat 3 for clamping circular gold jewelry. A porous ball bearing 47 is tumbling at the end of the clamping rod 46 to assist in clamping and adjusting the circular gold jewelry; Connecting plate 43 is symmetrically arranged on clamp seat 3, and is filled with oil for mounting fixed seat 44; The protrusions 52 are evenly distributed inside the clamping rod 46 and are used to adjust the fixed and movable states of the porous ball bearing 47. The driving components are symmetrically arranged on the clamp base 3 and are used to drive the clamping rod 46 to move. The control component, located on the clamp base 3, is used to adjust the angle of the circular gold jewelry; The linkage component, located on the fixture seat 3, is used to drive the adjustment component to adjust the fixed or rotating state of the porous ball 47.

[0035] In practice, there are several clamping rods 46 arranged symmetrically and densely above the clamping base 3. When the circular gold jewelry is placed vertically on the clamping base 3, the operation of the driving component can move the clamping rods 46 in the opposite direction. The several clamping rods 46 can clamp and fix the circular gold jewelry. There are also several protrusions 52. One end of some of the protrusions 52 is inserted into the hole on the surface of the porous ball 47. The porous ball 47 is limited by the protrusions 52 and cannot rotate. Therefore, the circular bracelet can be clamped more stably. The engraving drill bit 2 can then engrave the surface of the circular bracelet.

[0036] The driving component includes an electric push rod 4 fixed to the inner wall of the clamp seat 3; One end of the electric push rod 4 is fixedly connected to a movable plate 41; A clamping plate 42 is fixedly connected to the top of the movable plate 41; The clamping plate 42 is slidably sleeved with the clamping seat 3; The fixed base 44 is fixedly sleeved with the clamping plate 42; A first spring 45 is fixedly connected to the inner wall of the fixed base 44; One end of the first spring 45 is fixedly connected to the clamping rod 46; The clamping rod 46 is slidably connected to the fixed base 44.

[0037] In practice, activating the two electric push rods 4 can move the clamping rods 46 on both sides in opposite directions via the moving plate 41. The circular gold jewelry is placed between the clamping rods 46 on both sides, and the clamping rods 46 on both sides can securely hold the circular gold bracelet.

[0038] A sealing block 5 is slidably connected inside the clamping rod 46; A circular arc groove is provided on one side of the sealing block 5, and grooves are evenly provided on the inner wall of the circular arc groove; A second spring 51 is fixedly connected to the inner wall of the groove; One end of the second spring 51 is fixedly connected to the protrusion 52; The protrusion 52 is slidably connected to the groove.

[0039] One end of the protrusion 52 is curved.

[0040] In practice, the clamping rod 46 is filled with oil, and the sealing block 5 is tightly attached to the inner wall of the clamping rod 46 due to the resistance of the oil. The inner wall of the ball groove at the end of the clamping rod 46 has several channels. The protrusion 52 can be inserted into the hole on the surface of the ball through the channel. The porous ball 47 is fixed by the protrusion 52 and will not rotate, thus clamping the ring-shaped gold jewelry more stably.

[0041] The control components include a bearing 7 embedded in the inner wall of the clamp seat 3; The inner ring of bearing 7 is uniformly and fixedly connected with connecting rods 71; One end of the connecting rod 71 is fixedly connected to an adjusting wheel 73; The other end of the connecting rod 71 is fixedly connected to a rotating block 72.

[0042] 5. A highly adaptable, change-free fixture based on intelligent CNC machining according to claim 4, characterized in that: Adjustment wheel 73 has a circular ring structure; The top of the clamp base 3 is provided with a through slot; The adjusting wheel 73 extends through the slot to the outside of the clamp seat 3.

[0043] Please see Figures 1 to 13 In practice, rotating the rotating block 72 can drive the adjusting wheel 73 to rotate through the connecting rod 71. The surface of the adjusting wheel 73 is made of rubber or other materials that can increase friction resistance. The bottom of the circular gold jewelry is in contact with the adjusting wheel 73. The rotation of the adjusting wheel 73 can drive the circular gold jewelry to rotate through friction. This rotation can be done manually, which makes it easier to make precise adjustments to the angle according to the carving requirements.

[0044] A groove is provided on one side of the rotating block 72, and a third spring 82 is fixedly connected to the inner wall of the groove; One end of the third spring 82 is fixedly connected to the push block 81; A movable tube 8 is fixedly connected to one side of the block 81; The movable tube 8 is connected to the adjusting wheel 73.

[0045] In practice, pressing the button 81 can move the moving tube 8. The moving tube 8 passes through the adjusting wheel 73, and the moving tube 8 will not affect the adjusting wheel 73 when it moves.

[0046] The linkage component includes an adjusting cylinder 9 containing oil, which is fixed inside the clamp seat 3; A fourth spring 91 is fixedly connected to the inner wall of the adjusting cylinder 9; A sealing plate 95 is fixedly connected to one end of the fourth spring 91; The inner wall of the adjusting cylinder 9 is fixedly connected to the first flexible hose 482; One end of the first flexible hose 482 is fixedly connected to the flexible connecting tube 481; Both ends of the flexible connecting pipe 481 are fixedly connected to oil pipes 48; Oil pipe 48 is fixedly connected to connecting plate 43; A second flexible hose 483 is uniformly fixedly connected to one side of the connecting plate 43; The second hose 483 passes through the fixed base 44 and extends into the interior of the clamping rod 46; The second hose 483 is fixedly connected to the clamping rod 46.

[0047] In practice, the first flexible hose 482, the second flexible hose 483, and the flexible connecting pipe 481 are all flexible hoses. The flexible hoses can change their angle and orientation without affecting the movement of the clamping plate 42 or the clamping of the circular gold jewelry.

[0048] The adjusting cylinder 9 has a sliding connection to a push block 93 inside; A fifth spring 92 is fixedly connected to the top of the push block 93; One end of the fifth spring 92 is fixedly connected to the adjusting cylinder 9; A protruding rod 94 is fixedly connected to the top of the push block 93.

[0049] In practice, pressing the button 81 can move the moving tube 8. When the moving tube 8 moves, it will pass through the protrusion 94. The protrusion 94 will be squeezed and move into the interior of the adjusting cylinder 9. The push block 93 pushes the sealing plate 95 downward. The sealing plate 95 and the adjusting cylinder 9 are sealed. Therefore, the downward movement of the sealing plate 95 will draw the oil in the first hose 482 into the adjusting cylinder 9 through negative pressure. The first hose 482 can draw out a part of the oil inside the clamping rod 46 through the flexible connecting tube 481, the oil pipe 48 and the second hose 482. The sealing block 5 moves in the opposite direction of the porous ball 47 through negative pressure, so that all the protrusions 52 are disengaged from the porous ball 47 and the porous ball 47 is no longer fixed.

[0050] The top of the protruding rod 94 extends to the outside of the adjusting cylinder 9; The protruding rod 94 is slidably connected to the adjusting cylinder 9; The top of the protruding rod 94 is curved.

[0051] In practice, when the moving tube 8 passes the protruding rod 94, the top of the protruding rod 94 is an arc surface. When it is obstructed by the inner wall of the moving tube 8, it will move into the adjusting cylinder 9. When the push block 81 is released, the push block 93 is reset by the fifth spring 92, and the sealing plate 95 is reset by the fourth spring 91, so that the oil can be pushed back and the porous ball 47 can be fixed again.

[0052] One end of the adjusting tube 9 extends into the interior of the moving tube 8.

[0053] Working principle: When using this highly adaptable, non-replaceable fixture based on intelligent CNC machining, first, place the circular gold jewelry vertically on the fixture base 3. Start the two electric push rods 4, which can drive the clamping rods 46 on both sides to move in opposite directions through the moving plate 41. The circular gold jewelry is placed between the clamping rods 46 on both sides, and the clamping rods 46 on both sides can clamp the circular gold bracelet. There are also several protrusions 52. One end of some of the protrusions 52 is inserted into the hole on the surface of the multi-hole ball 47. The multi-hole ball 47 is limited by the protrusions 52 and cannot rotate, so the circular bracelet can be clamped more stably. The engraving drill bit 2 can then engrave the surface of the circular bracelet.

[0054] When the angle of the ring-shaped gold jewelry needs to be adjusted, pressing the button 81 can move the moving tube 8. When the moving tube 8 moves, it will pass through the protrusion 94. The protrusion 94 will be squeezed and move into the interior of the adjusting cylinder 9. The push block 93 pushes the sealing plate 95 downward. The sealing plate 95 and the adjusting cylinder 9 are sealed. Therefore, the downward movement of the sealing plate 95 will draw the oil in the first hose 482 into the adjusting cylinder 9 through negative pressure. The first hose 482 can draw out a part of the oil inside the clamping rod 46 through the flexible connecting tube 481, the oil pipe 48 and the second hose 482. The sealing block 5 moves in the opposite direction of the porous ball 47 through negative pressure, so that all the protrusions 52 are separated from the porous ball 47. The porous ball 47 is no longer fixed and can rotate under force. While pressing the button 81, rotate the rotating block 72. The rotating block 72 drives the adjusting wheel 73 to rotate through the connecting rod 71. The outer wall of the adjusting wheel 73 is made of rubber or other materials that can increase friction. When placing the ring-shaped gold jewelry, press its bottom onto the adjusting wheel 73. The rotation of the adjusting wheel 73 can drive the ring-shaped gold jewelry to rotate. The multi-hole ball 47 rotates under force and will not hinder the rotation of the ring-shaped gold jewelry. The angle of the ring-shaped gold jewelry can be adjusted according to the carving requirements. After adjusting the angle of the circular gold jewelry, release the push block 81 and the rotating block 72. The push block 93 is reset by the fifth spring 92, and the sealing plate 95 is reset by the fourth spring 91, which pushes the oil back and fixes the porous ball 47 again.

[0055] It should be noted that the porous ball bearing 47 has several holes and several protrusions 52 on its surface. When it is necessary to fix the porous ball bearing 47, by probability, some of the protrusions 52 will always be inserted into the holes of the porous ball bearing 47. In addition, even if all the protrusions 52 inside the clamping rod 46 are not inserted into the interior of the porous ball bearing 47, the number of clamping rods 46 is also multiple. The remaining porous ball bearings 47 on the clamping rods 46 can also be fixed to fix the circular gold jewelry without affecting the fixing effect.

[0056] Although the present invention 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 invention should be included within the protection scope of the present invention.
