It only requires a chuck to complete the laser cutting work. However, the chuck structure adopts a single-action and shaft clamping type, which can only process round and square tubes. It cannot process flat tubes or non-closed sized workpieces. The limitation of the processing range cannot meet the needs of the rapid development of the market.

[0056] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting up a base, a fixed support, a mounting shaft, a synchronous gear, a cylinder seat, a cylinder, an end cover, a mounting base, a synchronous rack, and a status control unit, when in use, the chuck is vented through an external compressed air unit, the air circuit drives the cylinder to run, the cylinder drives the end cover, mounting base, and synchronous rack to move, and the movement of the synchronous rack drives the synchronous gear to rotate. Since one synchronous gear corresponds to two synchronous racks, a linkage effect is formed, improving the movement accuracy of the synchronous rack, mounting base, and end cover. In each group, the two opposite mounting bases drive the corresponding jaw mechanism to move closer to each other, thereby clamping the workpiece. After clamping the workpiece, it is more stable, improving the self-centering accuracy of the laser power, and thus improving... This design improves the precision of laser cutting. Furthermore, due to the staggered arrangement of the two sets of chuck mechanisms, the workpiece can be clamped and fixed in four vertically distributed directions, making it suitable for various types of workpieces. Compared to traditional structures, it is no longer limited to round or square tubes, offering a wider range of applications. During clamping, the rotation direction of the synchronous gear is controlled by the status control unit, ensuring that the chuck mechanism can only move towards the workpiece for clamping and fixing. Even if there is a problem with the pneumatic circuit, the clamping will not loosen, providing sufficient time and space to handle faults promptly and preventing defective products due to pneumatic circuit failures. After processing, the mounting shaft is moved and its position adjusted by the status control unit, allowing the synchronous gear to return to its original position along with the mounting base and end cap.

Detailed Implementation

[0066] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0067] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0068] like Figure 1 , Figure 2 The diagram shown is a schematic representation of a laser-powered chuck with a cylinder-driven gear linkage synchronization mechanism according to an embodiment of the present invention, comprising:

[0069] Matrix;

[0070] A fixed support 1 is fixed in the base body, and the base body includes a main shell 9 and a front cover plate 10.

[0071] Mounting shaft 2, which is nested inside and coaxial with the fixed support body 1;

[0072] Synchronizing gears 3, two of which are provided and mounted on mounting shaft 2;

[0073] Cylinder seat 4, the cylinder seat 4 is provided in two sets and vertically distributed, each set of the cylinder seat 4 is provided on both sides of the synchronous gear 3;

[0074] Cylinder 5, which is mounted on cylinder base 4, and is connected to an external compressed air unit;

[0075] End cap 6, which is fixedly connected to the output end of cylinder 5;

[0076] Mounting base 7, which is fixed to end cover 6;

[0077] Synchronous rack 8, which is fixed on mounting base 7, and is meshed with corresponding synchronous gear 3;

[0078] The main housing 9 is provided with a state control unit 200 for controlling its state. The state control unit 200 is used to control the position and rotation direction of the mounting shaft 2.

[0079] The mounting base 7 is connected to a claw mechanism 100 that slides with the base body, and the clamping positions of the two sets of claw mechanisms 100 connected to the mounting base 7 are staggered.

[0080] In this embodiment of the invention, during use, the chuck is ventilated by an external compressed air unit, and the air circuit drives the cylinder 5 to operate. The cylinder 5 moves the end cover 6, the mounting base 7, and the synchronous rack 8. The movement of the synchronous rack 8 drives the synchronous gear 3 to rotate. Since one synchronous gear 3 corresponds to two synchronous racks 8, a linkage effect is formed, improving the movement accuracy of the synchronous rack 8, the mounting base 7, and the end cover 6. In each group, the two opposing mounting bases 7 drive the corresponding jaw mechanism 100 to move closer to each other, thereby clamping the workpiece. After clamping the workpiece, it is more stable, improving the self-centering accuracy of the laser power, and thus improving the accuracy of laser cutting. Furthermore, because the positions of the two sets of jaw mechanisms 100 are staggered... It can clamp and fix workpieces in four vertically distributed directions, and is applicable to various types of workpieces. Compared with traditional structures, it is no longer limited to round tubes and square tubes, and has a wider range of applications. During the clamping process, the rotation direction of the synchronous gear 3 is controlled by the state control unit 200, so that the chuck mechanism 100 can only move towards the workpiece to clamp and fix it. Even if there is a problem with the air circuit, there will be no loosening of the clamp. It has the time and space to deal with the fault in time, and there will be no defective products due to air circuit failure. After the processing is completed, the installation shaft 2 is moved by the state control unit 200 to adjust its position, so that the synchronous gear 8 can follow the installation seat 7 and end cover 6 to reset.

[0081] like Figure 1 , Figure 2 , Figure 3As shown, in a preferred embodiment of the present invention, the front cover plate 10 is fixed to the front side of the main housing 9, and the front cover plate 10 is slidably engaged with the claw mechanism 100.

[0082] In this embodiment of the invention, this configuration allows a four-cylinder structure to be placed within a limited space. The internal transmission uses precision gears for synchronous transmission, and the linear path is guided by a high-precision guide rail, which improves the compatibility of incoming material processing.

[0083] like Figure 1 , Figure 2 As shown, in another preferred embodiment of the present invention, the claw mechanism 100 includes:

[0084] The sliding plate 13 slides in contact with the front cover plate 10, and the sliding plate 13 is fixedly connected to the mounting base 7 via a connecting slider;

[0085] Fixing seat 11, the fixing seat 11 is fixed on the front cover plate 10 and located on both sides of the slide plate 13;

[0086] Guide rod 12, the guide rod 12 is fixed to the side of the fixed base 11 near the slide plate 13, and the guide rod 12 is slidably connected to the slide plate 13;

[0087] The gripper 14 is fixed to one end of the slide plate 13 away from the middle of the front cover plate 10;

[0088] The linear slide rail 15 is fixed to the front cover plate 10 on the side near the main housing 9, and the linear slide rail 15 is slidably connected to the connecting slider.

[0089] In this embodiment of the invention, when in use, the cylinder 5 drives the end cover 6 and the mounting base 7 to move, the mounting base 7 drives the connecting slider to move, the connecting slider moves along the linear slide rail 15, and has high linear accuracy. The connecting slider thereby drives the slide plate 13 to slide along the fixed base 11, moving towards the workpiece to clamp and fix it. Due to the length of the slide plate 13, the groove between the front cover plate 10 and the connecting slider can be sealed to prevent debris from entering.

[0090] like Figure 4 As shown, in another preferred embodiment of the present invention, the fixed support 1 is provided with a piston cavity 20, and the state control unit 200 includes:

[0091] A support sleeve 18 is disposed inside the piston cavity 20. The support sleeve 18 is coaxial with the fixed support body 1 and the mounting shaft 2. A fixing mechanism 600 for fixing the mounting shaft 2 is provided at the bottom of the support sleeve 18.

[0092] Piston plate 16, which slides in a sealed manner with the inner wall of piston chamber 20, and piston plate 16 is rotatably connected to support sleeve 18;

[0093] Positioning block 17, which is fixed on the inner wall of piston cavity 20 and located on both sides of piston plate 16, is used to limit the position of piston plate 16.

[0094] The first connecting pipe 19 is fixedly connected to the piston chamber 20 and is located on both sides of the piston plate 16.

[0095] A flow direction control mechanism 400 is fixedly connected to the piston chamber 20 and located on both sides of the piston plate 16;

[0096] The rotation control mechanism 300 is used to limit the rotation of the support sleeve 18. When the support sleeve 18 moves to a first predetermined position close to the synchronous gear 3, the support sleeve 18 and the mounting shaft 2 are in a free rotation state. When the support sleeve 18 moves to a second predetermined position away from the synchronous gear 3, the support sleeve 18 and the mounting shaft 2 are in a unidirectional rotation state (in this state, the rotation of the support sleeve 18 will cause the chuck mechanism 100 to clamp the workpiece).

[0097] The ends of the two first connecting pipes 19 away from the fixed support body 1 are respectively fixedly connected to the air outlet of the cylinder 5 and the air inlet of the external compressed air unit.

[0098] The ends of the two flow control mechanisms 400 that are away from the fixed support 1 are respectively fixedly connected to the air inlet of the cylinder 5 and the air outlet of the external compressed air unit.

[0099] In this embodiment of the invention, when in use, the first connecting pipe 19 is vented through the external compressed air unit, and the compressed air enters the piston chamber 20. When the compressed air pushes the piston plate 16 downward to the second predetermined position, the piston plate 16 drives the support sleeve 18 and the mounting shaft 2 to move. In this state, the synchronous gear 3 and the synchronous rack 8 are meshed. At this time, the support sleeve 18 and the mounting shaft 2 are in a unidirectional rotation state (in this state, the rotation direction of the support sleeve 18 will cause the chuck mechanism 100 to clamp the workpiece). At this time, the piston plate 16 cannot continue to move, and the compressed air enters the air inlet of the cylinder 5 through the flow control mechanism 400. The cylinder 5 works. At this time, even if there is a problem with the external compressed air unit or the air circuit, the synchronous gear 3 and the synchronous rack 8 will not run in reverse. There is time and space to deal with the fault in time, and there will be no defective products due to the air circuit failure.

[0100] like Figure 5 As shown, in another preferred embodiment of the present invention, the rotation control mechanism 300 includes:

[0101] A fixing component, which is mounted on the support sleeve 18, is a ratchet 21.

[0102] A limiting component is elastically hinged to the inner wall of the piston cavity 20, and the limiting component is slidably engaged with the fixing component.

[0103] The limiting component includes a pawl 22, a first elastic element 23, and a positioning element 24. The concave side of the pawl 22 is connected to the inner wall of the piston cavity 20 through the first elastic element 23. The positioning element 24 is fixed on the inner wall of the piston cavity 20 and is used to limit the convex side of the pawl 22.

[0104] In this embodiment of the invention, when in use, the mounting shaft 2 drives the ratchet 21 to rotate, the ratchet 21 squeezes the convex side of the pawl 22, and the pawl 22 compresses the first elastic element 23, so that it can rotate in one direction. When the support sleeve 18 drives the mounting shaft 2 away from the pawl 22, the pawl 22 cannot limit the ratchet 21. That is, when the support sleeve 18 moves to the first predetermined position close to the synchronous gear 3, the support sleeve 18 and the mounting shaft 2 are in a free rotation state.

[0105] like Figure 6 As shown, in another preferred embodiment of the present invention, the flow direction control mechanism 400 includes:

[0106] The second connecting air tube 25 is fixed to the fixed support body 1;

[0107] A frustoconical shell 26, the narrower end of which is fixedly connected to the second connecting air pipe 25;

[0108] The third connecting air pipe 27 is installed on the side of the frustum shell 26 away from the second connecting air pipe 25;

[0109] A sealing narrow plate 28 is provided, which slides in a sealing manner against the inner wall of the frustum shell 26.

[0110] The sealing wide plate 29 is slidably sealed to the inner wall of the frustum shell 26, and the sealing wide plate 29 is slidably connected to the sealing narrow plate 28;

[0111] The sealing wide plate 29 is connected to an elastic support assembly 500 that provides elastic support to it;

[0112] The sealing narrow plate 28 is provided with a second through groove 31, and the sealing wide plate 29 is provided with a first through groove 30 opposite to the second through groove 31;

[0113] In this embodiment of the invention, when in use, after the compressed air pushes the piston plate 16 to a predetermined position (first or second), the compressed air enters the second connecting air pipe 25 and pushes the sealing narrow plate 28 and the sealing wide plate 29 to move. When the sealing narrow plate 28 and the sealing wide plate 29 move to the position of the maximum inner diameter, the second through groove 31 and the first through groove 30 overlap. The compressed air enters the other side from the overlapping position and is delivered out through the third connecting air pipe 27.

[0114] In this embodiment, both the narrow sealing plate 28 and the wide sealing plate 29 are fixedly connected to guide blocks 32, which increase the contact area and improve movement stability.

[0115] like Figure 6 As shown, in another preferred embodiment of the present invention, the elastic support component 500 includes:

[0116] The slide rod 37 has one end fixedly connected to the sealing wide plate 29, and the other end of the slide rod 37 passes through the frustum shell 26;

[0117] The third elastic element 38 is sleeved on the slide rod 37 and is located between the inner wall of the frustum shell 26 and the sealing wide plate 29.

[0118] Anti-detachment block 39, which is fixed to one end of the slide rod 37 that passes through the frustum shell 26.

[0119] In this embodiment of the invention, when compressed air pushes the sealing narrow plate 28 and the sealing wide plate 29 to move, the sealing wide plate 29 drives the slide rod 37 and the anti-detachment block 39 to move, and compresses the third elastic element 38. After the command is executed, the sealing narrow plate 28 and the sealing wide plate 29 can be reset by the elastic force of the slide rod 37.

[0120] like Figure 7 As shown, in another preferred embodiment of the present invention, the fixing mechanism 600 includes:

[0121] Guide seat 33, the guide seat 33 is fixed on the inner wall of the support sleeve 18, and the guide seat 33 is nested in the mounting shaft 2;

[0122] The snap-fit ​​block 34 is slidably disposed within the guide seat 33, and one end of the snap-fit ​​block 34 is arc-shaped and partially nested within the mounting shaft 2;

[0123] The limiting slide groove 35 is slidably engaged with the snap-fit ​​block 34.

[0124] The second elastic element 36 has its two ends fixedly connected to the inner wall of the limiting slide groove 35 and the bottom wall of the snap-fit ​​block 34, respectively.

[0125] The sliding direction of the snap-fit ​​block 34 is perpendicular to the moving direction of the mounting shaft 2.

[0126] In this embodiment of the invention, by inserting the mounting shaft 2 into the fixed support body 1, the mounting shaft 2 is inserted into the support sleeve 18 and cooperates with the guide seat 33. At this time, the snap-fit ​​block 34 abuts against the inner wall of the mounting shaft 2. After the mounting shaft 2 abuts against the inner wall of the support sleeve 18, under the elastic force of the second elastic member 36, the limiting slide groove 35 is driven to nest in the guide seat 33, thereby completing the fixation.

[0127] The above embodiments of the present invention provide a laser power chuck with a cylinder direct-drive gear linkage synchronization mechanism. It comprises a base, a fixed support 1, a mounting shaft 2, a synchronization gear 3, a cylinder seat 4, a cylinder 5, an end cover 6, a mounting base 7, a synchronization rack 8, and a status control unit 200. In use, the chuck is vented by an external compressed air unit, driving the cylinder 5. The cylinder 5 moves the end cover 6, the mounting base 7, and the synchronization rack 8, which in turn drives the synchronization gear 3 to rotate. Since one synchronization gear 3 corresponds to two synchronization racks 8, a linkage effect is formed, improving the movement accuracy of the synchronization rack 8, the mounting base 7, and the end cover 6. In each group, two opposing mounting bases 7 drive the corresponding jaw mechanisms 100 to move closer together, thereby clamping the workpiece. The workpiece is more stable after clamping, improving the laser power output. The self-centering accuracy of the power system improves the precision of laser cutting. Furthermore, due to the staggered distribution of the two sets of chuck mechanisms 100, the workpiece can be clamped and fixed in four vertically distributed directions, making it suitable for various types of workpieces. Compared to traditional structures, it is no longer limited to round and square tubes, and has a wider range of applications. During the clamping process, the rotation direction of the synchronous gear 3 is controlled by the state control unit 200, so that the chuck mechanism 100 can only move towards the workpiece to clamp and fix it. Even if there is a problem with the air circuit, there will be no loosening of the clamping. It has the time and space to deal with the fault in time, and there will be no defective products due to air circuit failure. After the processing is completed, the installation shaft 2 is moved by the state control unit 200 to adjust its position, so that the synchronous gear 8 can follow the installation seat 7 and end cover 6 to reset.

[0128] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
