[0001] This invention relates to the field of drill bit loading technology, and more particularly to a drill bit loading structure. Background Technology

[0002] In the field of machining, drill bits, as common cutting tools, are widely used in drilling, reaming, and other processes. In automated machining equipment, the feed efficiency of drill bits directly affects the overall production cycle time.

[0003] In existing technologies, some automated equipment uses robotic arms to grip and load drill bits. However, due to the limitations of the robotic arm's gripper structure, traditional robotic arms can typically only load one drill bit at a time, which cannot meet the demands of high-efficiency production. During batch processing, the robotic arm needs to frequently travel between the storage area and the processing station, resulting in a long loading cycle and thus low drill bit loading efficiency.

Detailed Implementation

[0020] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0021] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] This invention provides a drill bit loading structure, such as... Figures 1 to 10 As shown, it includes a first conveying assembly 10, a second conveying assembly 20 and a feeding mechanism 30 connected in sequence. The first conveying assembly 10 is used to convey a plurality of drill bits arranged in a matrix along a first direction, and the second conveying assembly 20 is used to drive the feeding mechanism 30 to move linearly along a second direction. The feeding mechanism 30 includes a rotating component 31, a feeding cylinder 32, and a clamping cylinder 33. A first clamping block 331 and a second clamping block 332 are slidably mounted on the clamping cylinder 33. A first clamping bar 34 is vertically mounted on the first clamping block 331, and a second clamping bar 35 corresponding to the first clamping bar 34 is vertically mounted on the second clamping block 332. Both the first clamping bar 34 and the second clamping bar 35 are used to clamp at least two drill bits. The feeding cylinder 32 drives the clamping cylinder 33 to move along a third direction. The clamping cylinder 33 drives the first clamping bar 34 and the second clamping bar 35 to move closer or further apart. The rotating component 31 drives the feeding cylinder 32 to rotate around a second direction, thereby realizing the rotational feeding of the drill bit. The first, second, and third directions are perpendicular to each other. In this embodiment, because the first, second, and third directions are perpendicular to each other, the motion planning of the drill bit feeding structure is more reasonable, allowing for efficient operation within space, thus achieving complex motion paths while ensuring safety and stability.

[0024] It should be noted that the drill bit feeding structure provided by this invention, through the first conveying component 10, transports the matrix-arranged drill bits to the feeding mechanism 30, which not only ensures the orderly arrangement of the drill bits but also improves the feeding efficiency and reduces manual intervention and its resulting errors. The use of the feeding cylinder 32 and the clamping cylinder 33 in conjunction enables automated drill bit feeding. The first clamping bar 34 and the second clamping bar 35 clamp drill bits of different sizes and shapes, and can clamp at least two drill bits simultaneously, increasing the adaptability of the equipment and improving the efficiency of drill bit feeding. The rotating component 31 drives the feeding cylinder 32 to rotate around a second direction, realizing rotary feeding of the drill bits, making the matching and positioning of the drill bits more flexible and efficient in different application scenarios. Therefore, this invention solves the technical problem of low drill bit quantity per feeding by the robotic gripper in existing feeding structures.

[0025] like Figures 1 to 5 As shown, the number of clamping cylinders 33 is set to two, and the two clamping cylinders 33 are arranged side by side along the second direction; Each clamping cylinder 33 is provided with a first clamping block 331 and a second clamping block 332. Each first clamping block 331 is provided with a first clamping strip 34, and each second clamping block 332 is provided with a second clamping strip 35. In this embodiment, the feeding cylinder 32 drives the two clamping cylinders 33 to move synchronously in a third direction.

[0026] It should be noted that the parallel arrangement of the two clamping cylinders 33 allows for the simultaneous processing of multiple drill bits, with each clamping cylinder 33 holding a separate set of drill bits, further improving the drilling bit loading efficiency. By setting up two clamping cylinders 33 and combining them with the synchronous drive of the loading cylinder 32, a highly efficient, stable, and flexible drilling bit loading system is formed. This system not only improves production efficiency but also ensures operational safety and reliability, adapting to various industrial needs.

[0027] like Figures 1 to 8 As shown, the feeding mechanism 30 also includes a connecting pipe 36. The two ends of the connecting pipe 36 are respectively embedded with a first movable rod 371 and a second movable rod 372. The first movable rod 371 is connected to a first clamping block 331 on one of the clamping cylinders 33, and the second movable rod 372 is connected to a second clamping block 332 on the other clamping cylinder 33. The outer wall of the connecting pipe 36 is provided with a boss 361. The connecting pipe 36 is fitted with a first compression spring 381 and a second compression spring 382 at intervals. One end of the first compression spring 381 abuts against the first clamping block 331 on one of the clamping cylinders 33, and the other end of the first compression spring 381 abuts against the boss 361. One end of the second compression spring 382 abuts against the second clamping block 332 on the other clamping cylinder 33, and the other end of the second compression spring 382 abuts against the boss 361.

[0028] It should be noted that when the clamping cylinder 33 drives the first clamping block 331 and the second clamping block 332 to move relatively close, the first clamping bar 34 and the second clamping bar 35 clamp at least two drill bits. The clamping force on the drill bits far from the clamping center will decrease. The first clamping block 331 on one of the clamping cylinders 33 is clamped and secured by the elastic force of the first compression spring 381, and the second clamping block 332 on the other clamping cylinder 33 is clamped and secured by the elastic force of the second compression spring 382, ​​thereby increasing the clamping stress on the drill bits. Furthermore, the first compression spring 381 and the second compression spring 382 also have an elastic function, which can buffer the impact force and external vibration during drill bit clamping, helping to absorb excess energy during clamping, reducing the risk of wear and damage to the equipment when subjected to impact, extending the service life of the equipment, and ensuring stable feed of the drill bits.

[0029] like Figures 4 to 8As shown, the first clamping bar 34 has at least two first clamping grooves 341 on the side away from the first clamping block 331, and the second clamping bar 35 has at least two second clamping grooves 351 corresponding to the first clamping grooves 341 on the side away from the second clamping block 332. Both the first clamping grooves 341 and the second clamping grooves 351 are used to clamp the drill bit.

[0030] It should be noted that clamping the same drill bit using corresponding first clamping slots 341 and second clamping slots 351 increases the stability and firmness of the clamping, ensuring reliable support for the drill bit under different working conditions and preventing it from slipping or falling off during loading. The use of multiple first clamping slots 341 and multiple second clamping slots 351 allows for simultaneous loading of multiple drill bits, significantly improving clamping efficiency and saving production and operation time, especially in high-volume production lines, thus enhancing overall work efficiency. The combined use of the first clamping slots 341 and second clamping slots 351 effectively disperses clamping force, preventing stress concentration and reducing damage and wear to the drill bit. This is particularly beneficial when clamping high-value drill bits, better protecting the tool's integrity.

[0031] like Figures 4 to 8 As shown, the boss 361 and the connecting pipe 36 are integrally formed. The boss 361 is provided with a mounting surface 3611, and an adsorption pipe 362 is installed on the mounting surface 3611. The adsorption pipe 362 is connected to the negative pressure device, which is a well-known device in the art and will not be described in detail here. The first clamping groove 341 has a first adsorption port 342, and the second clamping groove 351 has a second adsorption port 352. The adsorption tube 362, the first adsorption port 342, and the second adsorption port 352 are all interconnected. In this embodiment, the end of the first movable rod 371 away from the connecting tube 36 is embedded in the first clamping block 331 and abuts against the first clamping strip 34. The end of the second movable rod 372 away from the connecting tube 36 is embedded in the second clamping block 332 and abuts against the second clamping strip 35. By using the adsorption tube 362, the first adsorption port 342, and the second adsorption port 352 to perform negative pressure adsorption on the drill bit, the technical problem of reduced clamping force of the first clamping strip 34 and the second clamping strip 35 on the edge of the drill bit when multiple drill bits are clamped is solved.

[0032] Specifically, the first movable rod 371 is provided with a first adsorption channel 3711 communicating with the inner cavity of the connecting tube 36, and the other end of the first adsorption channel 3711 is connected to the first adsorption port 342. The second movable rod 372 is provided with a second adsorption channel 3721 communicating with the inner cavity of the connecting tube 36, and the other end of the second adsorption channel 3721 is connected to the second adsorption port 352. The first clamping bar 34 is provided with a first connecting channel 343 for connecting the first adsorption channel 3711 and the first adsorption port 342. The second clamping bar 35 is provided with a second connecting channel 353 for connecting the second adsorption channel 3721 and the second adsorption port 352.

[0033] It should be noted that the first adsorption port 342 and the second adsorption port 352 provide negative pressure adsorption to the drill bit held on the two clamping cylinders 33, further enhancing the clamping force of the drill bit and ensuring the stability of the drill bit loading. The connection between the adsorption tube 362 and the negative pressure device ensures the efficient implementation of the adsorption function. The negative pressure device can continuously provide stable suction, ensuring the safety and stability of the drill bit during the clamping process and effectively preventing the drill bit from falling or shifting. The first adsorption channel 3711 and the second adsorption channel 3721 make the transmission of the adsorption airflow more direct and efficient, reducing the resistance of the airflow path and ensuring that the adsorption effect of the first adsorption port 342 and the second adsorption port 352 remains at an optimal level, adapting to the needs of different operating conditions.

[0034] It should also be noted that when the clamping cylinder 33 causes the drill bit to move due to external force or vibration, this movement will cause instantaneous stress changes. The first compression spring 381 and the second compression spring 382 can absorb these dynamic stresses, reducing the impact on the clamping cylinder 33, the first adsorption channel 3711, and the second adsorption channel 3721. In terms of adsorption performance, the compression springs help maintain the sealing around the adsorption port, reduce air leakage, and ensure the stability of the negative pressure, thereby enhancing the adsorption force. There is a significant synergistic effect between the first compression spring 381 and the first adsorption channel 3711, and between the second compression spring 382 and the second adsorption channel 3721. Through effective stress management and adsorption force optimization, the first compression spring 381 and the second compression spring 382 provide the necessary support and elasticity during clamping, which helps to improve the quality and stability of adsorption, thereby ensuring the safety and reliability of the drill bit during clamping and transportation.

[0035] In addition, when the clamping cylinder 33 drives the first clamping block 331 and the second clamping block 332 to move away, the first movable rod 371 and the second movable rod 372 are retracted, causing the first compression spring 381 and the second compression spring 382 to be further compressed. When the first movable rod 371 contacts the second movable rod 372, neither the first adsorption channel 3711 nor the second adsorption channel 3721 is connected to the adsorption tube 362, so that neither the first adsorption port 342 nor the second adsorption port 352 has negative pressure adsorption force. This prevents the drill bit from being adsorbed by the first adsorption port 342 and the second adsorption port 352 after the first clamping bar 34 and the second clamping bar 35 have moved away, ensuring that the drill bit can be loaded smoothly. When the clamping cylinder 33 releases its grip, the negative pressure in the connecting pipe 36 is cut off through the contact between the first movable rod 371 and the second movable rod 372, preventing the first suction port 342 and the second suction port 352 from continuing to provide negative pressure, thus ensuring that the drill bit can be fed smoothly and solving the technical problem of the drill bit being sucked up due to excessive negative pressure.

[0036] like Figures 4 to 8 As shown, the first clamping groove 341 includes two first clamping inclined surfaces 3411 arranged at an angle, and a first clamping plane 3412 is connected between the two first clamping inclined surfaces 3411. The first suction port 342 is disposed on the first clamping plane 3412. The second clamping groove 351 includes two second clamping inclined surfaces 3511 arranged at an angle, and a second clamping plane 3512 is connected between the two second clamping inclined surfaces 3511. The second suction port 352 is disposed on the second clamping plane 3512.

[0037] It should be noted that a stable clamping area can be formed by two clamping ramps set at an angle. When the clamping bar retracts and clamps, the drill bit will naturally be centered in the guide groove, ensuring the stability of the clamping. This not only reduces the risk of slippage or displacement of the drill bit during clamping but also improves the accuracy of drill bit clamping. Positioning the first suction port 342 and the second suction port 352 on the clamping plane allows the suction force to act directly on the clamped drill bit surface, maximizing the suction effect. Effective negative pressure securely holds the drill bit, reducing the risk of it falling due to vibration or other mechanical impacts.

[0038] It should also be noted that the arrangement of the first clamping inclined surface 3411 and the second clamping inclined surface 3511 optimizes the stress distribution applied to the clamping bar, resulting in a more uniform transmission of clamping force and reducing damage to the clamping bar or clamping groove caused by excessive force concentration. By changing the angles of the first clamping inclined surface 3411 and the second clamping inclined surface 3511, the first clamping groove 341 and the second clamping groove 351 can adapt to drill bits of different shapes and sizes. Users can adjust the settings of the first clamping groove 341 and the second clamping groove 351 within a certain range to clamp various types of drill bits, enhancing the system's flexibility and versatility.

[0039] like Figures 4 to 9 As shown, a sliding rod 391 is slidably connected to the two first clamping blocks 331 and the two second clamping blocks 332. A connector 392 is connected between the sliding rod 391 and the boss 361. A third compression spring 383 is sleeved on the connector 392. The connector 392 has a first abutment surface 39211, and the boss 361 has a second abutment surface 3612. The first abutment surface 39211 and the second abutment surface 3612 respectively abut against the two ends of the third compression spring 383. In specific implementation, both ends of the slide rod 391 are threaded with limiting rings to prevent the slide rod 391 from disengaging.

[0040] It should be noted that the slide bar 391, as a key component connecting the two first clamping blocks 331 and the two second clamping blocks 332, improves the stability of the overall structure, ensures that the relative movement between the first clamping blocks 331 and the second clamping blocks 332 remains consistent, and reduces the risk of clamping instability caused by uneven operation. The third compression spring 383 provides elastic support during clamping. The main function of the third compression spring 383 is to absorb the impact and vibration during operation when clamping and releasing the drill bit, preventing wear of the first clamping blocks 331 and the second clamping blocks 332 under high-frequency operation and extending the service life of the equipment. During clamping, the synergistic effect of the slide bar 391 and the third compression spring 383 ensures that the generated clamping force is evenly distributed on the two clamping blocks. This uniform clamping force helps prevent the drill bit from tilting or rotating during clamping, ensuring accurate positioning of the drill bit, which is especially important during high-speed operation.

[0041] It should also be noted that if only one or two compression springs are used, the clamping block may lose stability when external factors (such as gravity or vibration) change. The coordinated operation of the three compression springs can maintain the stability of the clamping mechanism under external forces and improve the system's anti-interference capability. During clamping, especially at high speeds, external vibrations to the drill bit may cause displacement and instability. The combined design of the three compression springs can effectively absorb this vibration energy, reduce the impact on the clamping block and the drill bit, and reduce the possibility of loosening or damage caused by vibration. When the drill bit is subjected to vibration, the third compression spring 383 can improve the response speed of the feeding mechanism 30. For example, when external vibration increases, the third compression spring 383 can adjust the clamping force in time to maintain the clamping effect on the drill bit. The cooperation of the first compression spring 381 and the second compression spring 382 can also quickly adapt to these changes and maintain the stable operation of the system. The first compression spring 381, the second compression spring 382, ​​and the third compression spring 383 form a composite elastic support system that can dynamically adjust the clamping force according to operating conditions. The first and second compression springs 382 can provide the necessary force feedback according to the movement of the clamping block, and maintain a good clamping state even under dynamic conditions.

[0042] like Figures 4 to 10 As shown, the rotating assembly 31 includes a drive cylinder 311 connected to the second conveying assembly 20 and arranged along a third direction. A mounting base 312 is mounted on the drive cylinder 311. A rotating seat 313, which is connected to the telescopic rod of the drive cylinder 311, is hinged to the mounting base 312. A rotating plate 314 is fixedly connected to the rotating seat 313. A feeding cylinder 32 is mounted on the rotating plate 314. A clamping cylinder 33 is slidably connected to the rotating plate 314.

[0043] For example, the rotating plate 314 includes a first plate 3141, a second plate 3142, and a third plate 3143 connected vertically in sequence. A third slide rail 316 arranged along a third direction is fixedly installed on the third plate 3143, and a third slider 317 is slidably engaged with the third slide rail 316. A moving block 318 is fixedly connected to the third slider 317, and a third moving plate 319 is fixedly installed on the moving block 318. A clamping cylinder 33 is installed on the side of the third moving plate 319 away from the moving block 318. The rotating seat 313 is fixedly connected to the first plate 3141, and a feeding cylinder 32 is installed on the second plate 3142. The telescopic rod of the feeding cylinder 32 passes through the second plate 3142 and is connected to the moving block 318. A first buffer 3151 and a second buffer 3152, which are vertically distributed, are installed on the mounting base 312. Both the first buffer 3151 and the second buffer 3152 are used to buffer the rotational movement of the rotating seat 313.

[0044] It should be noted that, since the rotating plate 314 includes a first plate 3141, a second plate 3142, and a third plate 3143 connected vertically in sequence, it provides multi-level support and stability for the rotating assembly 31, enabling the rotating assembly 31 to achieve more complex movements in a smaller space, thereby improving the overall functional efficiency. When the telescopic rod of the drive cylinder 311 retracts, it pulls the rotating seat 313 to rotate. Due to the limitations of the first buffer 3151 and the second buffer 3152, the rotation angle of the rotating seat 313 is 0~90°. The rotating seat 313 drives the rotating plate 314 to rotate, which in turn drives the two clamping cylinders 33 to rotate, thereby realizing the 90-degree rotational feeding of the drill bit.

[0045] like Figures 1 to 3 As shown, the first conveying assembly 10 includes a first conveying base plate 11, on which a first movable plate 12 for driving the drill bit to move along a first direction is slidably connected; a first conveyor belt 13 for pulling the first movable plate 12 is wound on the first conveying base plate 11, and a first conveying motor 14 for driving the first conveyor belt 13 to move is mounted on the first conveying base plate 11. In this embodiment, the drill bit can be supported by a carrier plate, which is mounted on the first movable plate.

[0046] Specifically, two first slide rails 15 are fixedly installed on the first conveying base plate 11, and two first sliders 16 are slidably connected on each first slide rail 15. The first moving plate 12 is fixedly installed on the first slider 16.

[0047] It should be noted that the first conveyor motor 14 drives the first conveyor belt 13 to move, which in turn pulls the first moving plate 12 to move, causing the first slider 16 to move on the first slide rail 15. This, in turn, transports the drill bit to the feeding position, enabling the drill bit to be transported quickly and stably along the first direction, significantly improving the conveying efficiency of the drill bit and contributing to the overall smoothness of the production line. The first conveyor motor 14 drives the first conveyor belt to move, thereby controlling the movement of the first moving plate 12. This simplifies the complexity of the drive system while ensuring efficient energy transfer, resulting in smoother system operation and lower energy consumption.

[0048] like Figures 1 to 3 As shown, the second conveying assembly 20 includes a support rod 21 connected to the first conveying assembly 10. A second conveying base plate 22 is fixedly connected to the support rod 21. A second moving plate 23 is slidably connected to the second conveying base plate 22. The second moving plate 23 is used to drive the rotating assembly 31 to move along the second direction. A second conveyor belt 24 for pulling the second moving plate 23 is wound on the second conveyor base plate 22, and a second conveyor motor 25 for driving the second conveyor belt 24 to move is installed on the second conveyor base plate 22.

[0049] Specifically, two second slide rails 26 are fixedly installed on the second conveying base plate 22, and a second slider 27 is slidably connected to each second slide rail 26. The second moving plate 23 is fixedly installed on the second slider 27.

[0050] It should be noted that the second conveyor motor 25 drives the second conveyor belt 24 to move, which in turn pulls the second moving plate 23 to move, causing the second slider 27 to move linearly along the second slide rail 26. This, in turn, drives the feeding mechanism 30 to move, facilitating the feeding operation of the drill bit. The second conveyor motor 25, through the transmission of the second conveyor belt 24, drives the second moving plate 23 to move, simplifying the complexity of the drive system and enhancing the efficiency of energy transfer.

[0051] Working principle: Before operation, the first clamping bar 34 and the second clamping bar 35 are far apart from each other, the first movable rod 371 and the second movable rod 372 are in a retracted state, the first compression spring 381, the second compression spring 382 and the third compression spring 383 are all in a compressed state, and there is no negative pressure in the first suction port 342 and the second suction port 352. During operation, the first conveying assembly 10 conveys the drill bit to the feeding position, and the second conveying assembly 20 drives the feeding mechanism 30 to move to the feeding position. The feeding cylinder 32 starts working and drives the moving block 318 to move along the direction close to the drill bit. The moving block 318 drives the third moving plate 319 to move linearly. Since the two clamping cylinders 33 are installed on the third moving plate 319, the third moving plate 319 drives the two clamping cylinders 33 to move to the appropriate position. The clamping cylinders 33 provide clamping driving force, driving the first clamping block 331 and the second clamping block 332 to move closer to each other, thereby driving the first clamping bar 34 and the second clamping bar 35 to clamp at least two drill bits. The negative pressure adsorption of the first adsorption port 342 and the second adsorption port 352 ensures that the drill bits are firmly clamped. Then, the driving cylinder 311 pulls the rotating seat 313 to rotate, so that the rotating plate 314 drives the clamping cylinders 33 to rotate 90 degrees, thereby realizing the 90-degree feeding of the drill bit. After operation, the first clamping bar 34 and the second clamping bar 35 come into contact with each other, the first compression spring 381 and the second compression spring 382 can be in a compressed or stretched state, and the first movable rod 371 and the second movable rod 372 are in an extended state.
