Description

Technical Field

[0001] This invention relates to the field of five-axis machining technology, specifically to a laser five-axis machining center for milling rotary components. Background Technology

[0002] The five-axis laser machining center for milling rotary components integrates five-axis linkage, metal milling and laser processing. It is designed for rotary workpieces such as shafts and discs. The equipment has a high degree of freedom of movement and strong processing flexibility. It can complete multiple processes such as cutting, laser modification and precision forming in one go, which greatly reduces the number of clamping times. It balances processing accuracy and production efficiency and is suitable for precision machinery, aerospace and other fields. In the process of machining, in order to reduce costs, factories generally use universal fixtures to adapt to different workpieces. When machining rotating components with special shapes and large size spans, the clamping range and fitting shape of the universal fixture cannot match the shape of the new workpiece, which will result in a mismatch problem. This will cause the fixture to fail to fit the shape of the workpiece, and the clamping force will be unevenly distributed, which may cause the workpiece to shift during machining. After the workpiece shifts, it will deviate from the preset machining path, which will increase the defect rate of the workpiece. To address the above problems, the following solutions are proposed. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a five-axis laser machining center for milling rotary components, including a bed, a laser head fixedly mounted on the bottom of the inner wall of the bed, a rotary table rotatably mounted on the inner wall of the bed, a three-jaw chuck fixedly mounted on the top of the outer wall of the rotary table, and a clamping table fixedly mounted on the top of the outer wall of the three-jaw chuck. The center also includes: An adaptation mechanism is slidably disposed on the inner wall of the clamping table; The adaptation mechanism includes a lifting platform that is slidably connected to the inner wall of the clamping table, and a moving block that is slidably connected to the bottom of the inner wall of the clamping table. The protective mechanism is slidably installed on the inner wall of the mechanism. The cleaning mechanism is fixedly installed on the inner wall of the clamping table; The cleaning mechanism includes a compression rod fixedly connected to the bottom of the inner wall of the clamping table, and an inclined block slidably connected to the inner wall of the clamping table.

[0004] Preferably, the adapting mechanism includes: The force-applying component is slidably disposed on the inner wall of the clamping table; The force-bearing component is fixedly installed on the outer wall of the force-applying component; When the force-applying component moves a certain distance, it causes the force-receiving component to move as well.

[0005] Preferably, the protection mechanism includes: The attachment component is slidably disposed on the inner wall of the force-applying component; A reset component is fitted onto the inner wall of the attachment component. When the attachment component comes into contact with the surface of the workpiece, the attachment component is forced to move due to the resistance of the workpiece.

[0006] Preferably, the cleaning facility includes: The scraping component is fixedly installed on the inner wall of the clamping table; A collection component is rotatably positioned on the outer wall of the scraping component. The collecting component rotates when the external force from the scraping component is removed.

[0007] Preferably, the force-applying component includes an L-shaped rod slidably connected to the inner wall of the moving block; In this process, the worker places the workpiece on the surface of the lifting platform, causing the platform to move downwards. The three-jaw chuck then moves the moving block, and the L-shaped rod moves synchronously.

[0008] Preferably, the force-bearing components include a spring fixedly connected to the inner wall of the movable block, a movable plate rotatably connected to the top of the outer wall of the L-shaped rod, a sliding block slidably connected to the side wall of the movable block, and a limiting block fixedly connected to the top of the inner wall of the clamping table. When the L-shaped rod contacts the workpiece, it generates a thrust on the spring. When the L-shaped rod moves along the inner wall of the moving block, it forces the movable plate to rotate. When the movable plate rotates, it generates a thrust on the sliding block. When the moving block stops moving, the extended end of the movable plate contacts the surface of the limiting block, thus limiting the movable plate.

[0009] Preferably, the attachment component includes a shaped block slidably connected to the inner wall of the L-shaped rod, a spring piece fixedly connected to the inner wall of the L-shaped rod, and a rotating plate rotatably connected to the inner wall of the L-shaped rod. In this process, the irregularly shaped block first comes into contact with the workpiece. As the L-shaped rod continues to move, the irregularly shaped block is moved by the resistance of the workpiece and loses its restriction on the rotating plate.

[0010] Preferably, the reset assembly includes a torsion spring sleeved on the inner wall of the rotating plate, and a telescopic rod rotatably connected to the outer wall of the rotating plate; When the rotating plate is no longer restricted by the irregular block, it rotates and the telescopic rod moves accordingly. When the irregular block loses the thrust of the workpiece, it resets and drives the telescopic rod to move synchronously. When the telescopic rod moves, it applies a thrust to the rotating plate, forcing the rotating plate to rotate. When the rotating plate finishes rotating, it is restricted by the irregular block again.

[0011] Preferably, the scraping assembly includes a collection block fixedly connected to the side wall of the L-shaped rod; As the lifting platform moves downward, it exerts pressure on the compression rod and continuously contacts the surface of the L-shaped rod. When the lifting platform is about to stop moving downward, it applies a pushing force to the inclined block, causing the inclined block to enter the interior of the lifting platform under the action of its own spring, thus completing the restriction of the lifting platform.

[0012] Preferably, the collection assembly includes a baffle plate rotatably connected to the top of the outer wall of the collection block, a flexible block fixedly connected to the bottom of the outer wall of the baffle plate, a torsion spring sleeved on the inner wall of the baffle plate, and a limiting rod fixedly connected to the bottom of the outer wall of the lifting platform. When the lifting platform moves down, it drives the limiting rod to move down synchronously. When the limiting rod is about to stop moving down, it contacts the baffle plate, causing the baffle plate to rotate under force. At this time, the baffle plate completes the sealing of the collection block.

[0013] The present invention has the following beneficial effects: (1) The present invention uses a three-jaw chuck to drive the moving block to move, and the L-shaped rod moves along with it. When the L-shaped rod contacts the workpiece, it generates a thrust on the spring and forces the movable plate to rotate. When the movable plate rotates, it generates a thrust on the sliding block, causing the sliding block to move upward under force. When the moving block stops moving, the extended end of the movable plate contacts the surface of the limiting block, and the movable plate is limited by several grooves on the side wall of the limiting block. With the above components, it can be adapted to rotating workpieces of different shapes and specifications, effectively fix them, greatly reduce the defect rate, and improve the processing accuracy and product stability.

[0014] (2) During the movement of the L-shaped rod of the present invention, the irregular block moves synchronously and the irregular block first contacts the workpiece. As the L-shaped rod continues to move, it applies a pushing force to the spring. When the rotating plate loses the restriction of the irregular block, the rotating plate rotates under the elastic force of the torsion spring. When the irregular block loses the pushing force of the workpiece, the irregular block drives the telescopic rod to reset. When the telescopic rod moves, it applies a pushing force to the rotating plate, forcing the rotating plate to rotate. When the rotating plate finishes rotating, it is restricted by the irregular block again. Through the above components, when the L-shaped rod contacts the surface of the workpiece, its contact area is increased, so that the unit area pressure under the same total clamping force is significantly reduced, effectively ensuring the roundness, coaxiality and other form and position tolerances of the parts.

[0015] (3) When the lifting platform moves down, it exerts pressure on the compression rod and continuously contacts the surface of the L-shaped rod. When the lifting platform is about to stop moving down, it applies a pushing force to the inclined block, so that the inclined block enters the interior of the lifting platform under the action of its own spring, thus completing the restriction of the lifting platform. When the lifting platform moves up, the lifting platform contacts the bottom inclined surface of the irregular block and applies a pushing force to the irregular block again. Through the above components, the slag, metal debris and oil stains attached to the surface of the L-shaped rod can be removed in time, and impurities can be prevented from damaging the fit between the L-shaped rod and the workpiece.

[0016] (4) When the lifting platform moves down, it continuously contacts the surface of the L-shaped rod, causing impurities on the surface of the L-shaped rod to fall down and enter the collection block. This causes the limiting rod to move down synchronously. When the limiting rod is about to stop moving down, the baffle plate rotates under force, causing the flexible block to rotate synchronously. When the baffle plate rotates, it applies pressure to the torsion spring, causing the torsion spring to be compressed and accumulate potential energy. At this time, the baffle plate completes the sealing of the collection block. Through the above components, the falling impurities are collected in a unified manner, preventing positioning errors caused by impurities from the source, ensuring stable processing dimensions, and reducing the scrap rate.

[0020] 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.

[0021] Example 1, please refer to Figures 1-8 This invention relates to a five-axis laser machining center for milling rotary components, comprising a bed 13, a laser head 14 fixedly mounted on the bottom of the inner wall of the bed 13, a rotary table 15 rotatably mounted on the inner wall of the bed 13, a three-jaw chuck 16 fixedly mounted on the top of the outer wall of the rotary table 15, and a clamping table 17 fixedly mounted on the top of the outer wall of the three-jaw chuck 16. The invention also includes: Adaptation mechanism 1 is slidably disposed on the inner wall of clamping table 17; The adaptation mechanism 1 includes a lifting platform 111 that is slidably connected to the inner wall of the clamping platform 17, and a moving block 112 that is slidably connected to the bottom of the inner wall of the clamping platform 17. Protection mechanism 2 is slidably installed on the inner wall of mechanism 1; Cleaning mechanism 3 is fixedly installed on the inner wall of clamping table 17; The cleaning mechanism 3 includes a compression rod 311 fixedly connected to the bottom of the inner wall of the clamping platform 17, and an inclined block 312 slidably connected to the inner wall of the clamping platform 17.

[0022] Adaptive mechanism 1 includes: Force application component 11 is slidably disposed on the inner wall of clamping table 17; Force-receiving component 12 is fixedly installed on the outer wall of force-applying component 11; The operator places the workpiece to be processed on top of the clamping table 17, then activates the three-jaw chuck 16 to fix the workpiece. After confirming that the clamping is secure, the laser head 14 and the rotary table 15 are activated. The rotary table 15 drives the workpiece to rotate, allowing the laser head 14 to mill any position on the workpiece. When the three-jaw chuck 16 is activated, it drives the force application component 11 to move. When the force application component 11 moves a certain distance, it generates a thrust on the force receiving component 12, causing the force receiving component 12 to move.

[0023] Protection agency 2 includes: The attachment component 21 is slidably disposed on the inner wall of the force application component 11; Reset component 22 is sleeved on the inner wall of attachment component 21; When the force-applying component 11 moves, it drives the attachment component 21 to move synchronously. When the attachment component 21 comes into contact with the surface of the workpiece, the attachment component 21 is resisted by the workpiece and is forced to move. When the attachment component 21 moves, the reset component 22 moves along with it.

[0024] Cleaning facility 3 includes: Scraping component 31 is fixedly installed on the inner wall of clamping table 17; Collection component 32 is rotatably mounted on the outer wall of scraping component 31; When the force-applying component 11 moves, it applies an external force to the scraping component 31, causing the scraping component 31 to move under the force. When the collecting component 32 loses the external force from the scraping component 31, it rotates.

[0025] Example 2, please refer to Figures 4-12 The present invention is a five-axis laser machining center for milling rotary components. Based on the first embodiment, the force application component 11 includes an L-shaped rod 113 that is slidably connected to the inner wall of the moving block 112. When the worker places the workpiece on the surface of the lifting platform 111, the lifting platform 111 is subjected to the pressure of the workpiece and moves downward. At this time, the three-jaw chuck 16 is activated, and the moving block 112 is moved by the three-jaw chuck 16. When the moving block 112 moves, it drives the L-shaped rod 113 to move synchronously. As the L-shaped rod 113 moves gradually, it comes into contact with the surface of the workpiece.

[0026] The force-bearing component 12 includes a spring 121 fixedly connected to the inner wall of the movable block 112, a movable plate 122 rotatably connected to the top of the outer wall of the L-shaped rod 113, a sliding block 123 slidably connected to the side wall of the movable block 112, and a limiting block 124 fixedly connected to the top of the inner wall of the clamping table 17. When the L-shaped rod 113 contacts the workpiece, the continuous movement of the moving block 112 causes the L-shaped rod 113 to experience resistance from the workpiece, causing it to move relative to the moving block 112. During this movement, the L-shaped rod 113 exerts a pushing force on the spring 121, causing the spring 121 to compress and accumulate potential energy. As the L-shaped rod 113 moves along the inner wall of the moving block 112, it forces the movable plate 122 to rotate. When the movable plate 122 rotates, it exerts a pushing force on the sliding block 123, causing the sliding block 123 to move upward. When the moving block 112 stops moving, the extended end of the movable plate 122 contacts the surface of the limiting block 124, and through several grooves on the side wall of the limiting block 124, it restricts the movable plate 122, preventing it from moving. This ensures that the L-shaped rods 113 do not shift during clamping.

[0027] The attachment component 21 includes a shaped block 211 that is slidably connected to the inner wall of the L-shaped rod 113, a spring piece 212 that is fixedly connected to the inner wall of the L-shaped rod 113, and a rotating plate 213 that is rotatably connected to the inner wall of the L-shaped rod 113. During its movement, the L-shaped rod 113 drives the irregularly shaped block 211 to move synchronously. Before the L-shaped rod 113 contacts the workpiece, the irregularly shaped block 211 contacts the workpiece first. As the L-shaped rod 113 continues to move, the irregularly shaped block 211 is subjected to the resistance of the workpiece and moves relative to the L-shaped rod 113. During its movement, the irregularly shaped block 211 gradually loses its restriction on the rotating plate 213 and applies a pushing force to the spring piece 212 during the movement, forcing the spring piece 212 to be compressed and accumulate potential energy.

[0028] The reset assembly 22 includes a torsion spring 221 sleeved on the inner wall of the rotating plate 213, and a telescopic rod 222 rotatably connected to the outer wall of the rotating plate 213; When the rotating plate 213 is no longer restricted by the irregular block 211, it rotates under the elastic force of the torsion spring 221. The telescopic rod 222 moves synchronously with the irregular block 211. After rotating, the rotating plate 213 contacts the surface of the workpiece. When the irregular block 211 loses the thrust of the workpiece, it gradually resets under the elastic force of the spring 212. When the irregular block 211 resets, it drives the telescopic rod 222 to move synchronously. Since the telescopic rod 222 is in a contracted state at this time, it applies a thrust to the rotating plate 213 when it moves, forcing the rotating plate 213 to rotate under force. During the rotation, it applies pressure to the torsion spring 221, causing the torsion spring 221 to be compressed and accumulate potential energy. When the rotating plate 213 finishes rotating, it is restricted by the irregular block 211 again.

[0029] The scraping assembly 31 includes a collection block 313 fixedly connected to the side wall of the L-shaped rod 113; When the worker places the workpiece on the surface of the lifting platform 111, the lifting platform 111 moves downward under force, and the downward movement of the lifting platform 111 exerts pressure on the compression rod 311, forcing the compression rod 311 to compress and accumulate potential energy, such as... Figure 9 As shown, when the lifting platform 111 moves downward, it continuously contacts the surface of the L-shaped rod 113. At this time, the irregular block 211 is pushed by the lifting platform 111, causing the rotating plate 213 to lose the restriction of the irregular block 211 and contact the surface of the lifting platform 111. When the lifting platform 111 is about to stop moving downward, it contacts the inclined surface of the inclined block 312 and applies a pushing force to the inclined block 312, causing the inclined block 312 to enter the interior of the lifting platform 111 under the action of its own spring, thus completing the restriction of the lifting platform 111 and preventing the lifting platform 111 from shaking during the processing. At this time, the lifting platform 111 does not exert a pushing force on the irregular block 211. When the lifting platform 111 moves upward, the lifting platform 111 contacts the bottom inclined surface of the irregular block 211 and applies a pushing force to the irregular block 211 again.

[0030] The collection component 32 includes a baffle plate 321 rotatably connected to the top of the outer wall of the collection block 313, a flexible block 322 fixedly connected to the bottom of the outer wall of the baffle plate 321, a torsion spring 323 sleeved on the inner wall of the baffle plate 321, and a limiting rod 324 fixedly connected to the bottom of the outer wall of the lifting platform 111. As the lifting platform 111 moves downward, it continuously contacts the surface of the L-shaped rod 113, causing impurities on the surface of the L-shaped rod 113 to fall off and enter the collection block 313, thus driving the limiting rod 324 to move downward synchronously. Figure 12 As shown, when the limiting rod 324 is about to stop moving downward, it contacts the protrusion at point F of the baffle plate 321 and exerts downward pressure on the protrusion at point F, causing the baffle plate 321 to rotate under force, which drives the flexible block 322 to rotate synchronously. When the baffle plate 321 rotates, it applies pressure to the torsion spring 323, causing the torsion spring 323 to be compressed and accumulate potential energy. At this time, the baffle plate 321 completes the sealing of the collecting block 313.

[0031] One specific application of this embodiment is as follows: The operator places the workpiece to be processed on the top of the clamping table 17, and then activates the three-jaw chuck 16 to fix the workpiece. After confirming that the clamping is firm, the laser head 14 and the rotary table 15 are activated. The rotary table 15 drives the workpiece to rotate, so that the laser head 14 can mill any position of the workpiece.

[0032] In actual processing, factories often use universal fixtures to adapt to different workpieces in order to reduce costs. However, when machining rotating components with special shapes and large size spans, the clamping range and fit of the universal fixture cannot match the shape of the new workpiece, resulting in a mismatch. This causes the fixture to fail to fit the workpiece shape, leading to uneven clamping force distribution and potential workpiece displacement during processing. This displacement causes the workpiece to deviate from the preset processing path, increasing the defect rate. When the operator places the workpiece on the surface of the lifting platform 111, the platform 111 experiences pressure from the workpiece and moves downwards. At this time, the three-jaw chuck 16 is activated, driving the moving block 112 to move. The moving block 112 moves synchronously, causing the L-shaped rod 113 to move synchronously. As the L-shaped rod 113 gradually moves, when it contacts the workpiece, the continuous movement of the moving block 112 causes the L-shaped rod 113 to experience resistance from the workpiece. The movable block 112 moves, and during the movement, the L-shaped rod 113 exerts a pushing force on the spring 121, causing the spring 121 to be compressed and accumulate potential energy. While the L-shaped rod 113 moves along the inner wall of the movable block 112, it forces the movable plate 122 to rotate. When the movable plate 122 rotates, it exerts a pushing force on the sliding block 123, forcing the sliding block 123 to move upward. When the movable block 112 stops moving, the extended end of the movable plate 122 contacts the surface of the limiting block 124, and through several grooves on the side wall of the limiting block 124, it completes the restriction of the movable plate 122, making the movable plate 122 unable to move. This ensures that several L-shaped rods 113 do not shift during clamping. With the above components, it can adapt to rotating workpieces of different shapes and specifications, effectively fix them, ensure that the positioning error of each clamping is controlled within a very small range, and ensure good consistency of the form and position tolerances of the entire batch of parts, greatly reducing the defect rate and improving the processing accuracy and product stability.

[0033] The number of the above components is not limited. Those skilled in the art can set it freely according to actual needs, as long as the above components are installed at the corresponding component connection positions.

[0034] Utilizing the characteristics of the L-shaped rod 113's movement, the L-shaped rod 113 drives the irregularly shaped block 211 to move synchronously during its movement. Before the L-shaped rod 113 contacts the workpiece, the irregularly shaped block 211 first contacts the workpiece. As the L-shaped rod 113 continues to move, the irregularly shaped block 211 experiences resistance from the workpiece and moves relative to the L-shaped rod 113. During its movement, the irregularly shaped block 211 gradually loses its restriction on the rotating plate 213 and, during the movement, interacts with the spring sheet. 212 applies a thrust, forcing the spring 212 to compress and accumulate potential energy. When the rotating plate 213 is no longer restrained by the irregular block 211, it rotates under the elastic force of the torsion spring 221. The telescopic rod 222 moves synchronously with the irregular block 211. After rotation, the rotating plate 213 contacts the surface of the workpiece. When the irregular block 211 loses the thrust from the workpiece, it gradually returns to its original position under the elastic force of the spring 212. During the resetting process, the irregular block 211... The telescopic rod 222 moves synchronously. Since the telescopic rod 222 is in a retracted state at this time, it applies a pushing force to the rotating plate 213 when it moves, forcing the rotating plate 213 to rotate under force. During the rotation, it applies pressure to the torsion spring 221, causing the torsion spring 221 to be compressed and accumulate potential energy. When the rotating plate 213 finishes rotating, it is again restricted by the irregular block 211. When dealing with workpieces such as thin-walled ceramic rotors and thin-walled stainless steel rotating shells, in order to fix them, the clamping force is concentrated at a local small point. The local compressive stress will exceed the strength limit of the ceramic, which will directly lead to the ceramic cracking and shattering, and the workpiece will be scrapped. Through the above components, when the L-shaped rod 113 contacts the surface of the workpiece, the contact area is increased, so that the unit area pressure under the same total clamping force is significantly reduced. This can prevent plastic deformation or ceramic cracking caused by local stress concentration. After the workpiece is released from the clamp after processing, the springback of the workpiece is small, which can effectively ensure the roundness, coaxiality and other geometric tolerances of the parts.

[0035] Utilizing the downward movement characteristic of the lifting platform 111, when the worker places the workpiece on the surface of the lifting platform 111, the lifting platform 111 is forced to move downward, and the downward movement of the lifting platform 111 exerts pressure on the compression rod 311, forcing the compression rod 311 to be compressed and accumulating potential energy, such as... Figure 9As shown, when the lifting platform 111 moves downward, it continuously contacts the surface of the L-shaped rod 113. At this time, the irregular block 211 is pushed by the lifting platform 111, causing the rotating plate 213 to lose the restriction of the irregular block 211 and contact the surface of the lifting platform 111. When the lifting platform 111 is about to stop moving downward, it contacts the inclined surface of the inclined block 312 and applies a pushing force to the inclined block 312, causing the inclined block 312 to enter the interior of the lifting platform 111 under the action of its own spring, thus completing the restriction of the lifting platform 111 and preventing the lifting platform 111 from shaking during processing. At this time, the lifting platform 111 does not exert a pushing force on the irregular block 211. When the lifting platform 111 moves upward, the lifting platform 111 and the L-shaped rod 113 continuously contact the surface of the L-shaped rod 113. The bottom inclined surface of the irregular block 211 contacts and applies a pushing force to the irregular block 211 again. During the laser processing, impurities such as molten metal slag, dust, and debris will be generated. These impurities will adhere to the surface of the L-shaped rod 113. If the molten impurities cool and solidify, they may also cause surface dents or protrusions, damaging the original flatness and reducing the surface flatness of the L-shaped rod 113, thus damaging the original surface accuracy and affecting the subsequent clamping fit. Through the above components, the molten slag, metal debris, and oil stains attached to the surface of the L-shaped rod 113 can be removed in time, preventing impurities from damaging the fit between the L-shaped rod 113 and the workpiece, preventing positioning offset and clamping errors in subsequent processing, and maintaining the processing accuracy requirements of the rotating component in the long term.

[0036] Taking advantage of the downward movement of the lifting platform 111, as it moves downward, it continuously contacts the surface of the L-shaped rod 113, causing impurities on the surface of the L-shaped rod 113 to fall off and enter the collection block 313, thus driving the limiting rod 324 to move downward synchronously. Figure 12 As shown, when the limiting rod 324 is about to stop moving downward, it contacts the protrusion at point F of the baffle plate 321 and exerts downward pressure on the protrusion at point F, causing the baffle plate 321 to rotate under force, which drives the flexible block 322 to rotate synchronously. When the baffle plate 321 rotates, it applies pressure to the torsion spring 323, causing the torsion spring 323 to be compressed and accumulate potential energy. At this time, the baffle plate 321 completes the sealing of the collecting block 313. When scraping off the impurities attached to the surface of the L-shaped rod 113, the impurities will fall into the inside of the clamping table 17. Long-term residual slag will wear down the internal structure of the clamping table 17, shorten its service life, and lead to a decrease in positioning accuracy. Through the above components, the fallen impurities are collected in a unified manner, preventing positioning errors caused by impurities from the source, ensuring stable processing dimensions, and reducing the scrap rate.
