Description

Technical Field

[0001] This utility model relates to the field of pneumatic chuck technology for laser tube cutting machines, and in particular to a novel gear-driven double-sided separating clamping mechanism laser power chuck. Background Technology

[0002] Currently, most high-precision large laser power chucks on the market adopt a single-sided four-jaw structure. Through the independent or linked design of the four jaws, they achieve high stability and micron-level repeatability positioning accuracy. They are especially suitable for adaptive clamping of complex cross-sections such as round tubes, square tubes, and irregularly shaped tubes in the laser cutting of metal tubes. These chucks usually integrate a pneumatic drive system with built-in closed cylinders and precision air circuit modules. Through air pressure conversion, they generate a strong thrust of more than 130kg per jaw. At the same time, combined with the inclined groove roller mechanism or gear rack transmission, they ensure the stability and accuracy of the synchronous movement of the four jaws and effectively suppress vibration and deviation during tube cutting.

[0003] However, especially when the processing requires switching to hard carbide (such as carbide jaws or pads) to improve clamping force or prevent workpiece damage, depending on the characteristics and cutting requirements of the tube (such as thin-walled easily deformable tubes or special profiles), the existing single-sided four-jaw chuck has significant limitations: because its structural design is usually optimized only for a single clamping surface, it cannot conveniently and efficiently integrate or switch hard carbide clamping modes. Therefore, in practical applications, to meet this process switching requirement, the operator often has to add an additional independent chuck specifically for hard carbide to the bed of the same laser tube cutting machine. This solution not only directly increases the purchase cost of the chuck itself, but also makes the overall structure of the machine tool more complex and bulky. It requires additional space reservation and structural reinforcement of the bed to support the second chuck and its drive system, and significantly extends the installation, commissioning and assembly cycle of the equipment. In addition, the dual chuck configuration also increases the complexity of system maintenance and potential sources of coordination errors.

[0004] Therefore, how to provide a novel gear-driven double-sided split clamping mechanism laser power chuck is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to propose a novel gear-driven double-sided split clamping mechanism laser power chuck, which solves the problems mentioned in the background art.

[0006] A novel gear-driven double-sided split clamping mechanism laser power chuck according to an embodiment of the present invention includes a base, a rotary bearing fixedly installed inside the base, and two sets of clamping mechanisms rotatably connected to both ends of the base through the rotary bearing; each set of clamping mechanisms includes a chuck body, a drive component, a sliding component, and a jaw; the two sets of chuck bodies are respectively fixedly connected to both sides of the inner ring of the rotary bearing, the drive component is disposed inside the chuck body, the sliding mechanism is disposed on the side of the chuck body, the jaw is disposed on the surface of the sliding component, and the drive component is disposed on the sliding component.

[0007] Each set of chuck bodies corresponds to four sets of sliding components and jaws, and the four sets of sliding components and jaws are arranged in a ring array with the axis of the chuck body as the array center.

[0008] The drive assembly includes a first synchronous gear ring, a second synchronous gear ring, a cylinder, a push shaft, and a synchronous pinion. The first and second synchronous gear rings are rotatably connected to the inner wall of the chuck body. The cylinder is fixedly installed inside the chuck body. The push shaft is fixedly installed at the output shaft end of the cylinder. The other end of the push shaft is fixedly installed on the inner wall of the first synchronous gear ring. The synchronous pinion is rotatably connected inside the chuck body and meshes with the inner walls of the first and second synchronous gear rings.

[0009] The drive assembly consists of four sets of cylinders, push shafts, and synchronizing pinions, arranged in a circular array with the chuck body's axis as the array center.

[0010] The sliding assembly includes a track groove, a slider, and a toothed groove. The track groove is fixedly installed on the surface of the chuck body, the slider is slidably connected inside the track groove, the toothed groove is opened on the side of the slider, the chuck is fixedly connected to the surface of the slider, and one end of the synchronizing pinion passes through the chuck body and extends into the interior of the track groove and meshes with the toothed groove.

[0011] The drive assembly also includes an air circuit module. There are two sets of air circuit modules. The two sets of air circuit modules are respectively disposed between the inner walls of the two sets of chuck bodies and the base. One end of each set of air circuit modules passes through the two sets of chuck bodies and is respectively disposed on the surface of the two sets of cylinders.

[0012] The base has a mounting groove on its surface, and a speed reducer is fixedly installed inside the mounting groove. A drive wheel is fixedly installed on the output shaft end of the speed reducer, and a driven gear is fixedly sleeved on the side of a set of chuck bodies. The driven gear and the drive wheel mesh with each other.

[0013] The number of jaws matches the number of chuck bodies; one set of jaws is a hard jaw, and the other set is a roller jaw.

[0014] The beneficial effects of this utility model are:

[0015] The chuck body features a double-sided square hole design. Within a limited space, a synchronized linkage mechanism with a pinion drive enables full-stroke clamping. Each side has four individually controlled jaws, while the double-sided design allows for the switching between four hard jaws and four roller jaws. This effectively improves chuck performance, clamping accuracy, and load-bearing capacity despite chuck size limitations. It also expands the pipe processing range, shortens the overall debugging and assembly time of the pipe cutter, and extends the chuck maintenance cycle. This significantly enhances the cutting effect and processing compatibility of the laser-powered chuck. A separate set of four jaws, each consisting of a base jaw and a top jaw, allows for both positive and negative jaw functions through top jaw switching. Soft jaws can also be provided upon request, achieving high centering accuracy after being machined (ground) to meet clamping requirements. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] refer to Figure 1-5 In this embodiment, a base 1 is included, and a rotary bearing 2 is fixedly installed inside the base 1. Two sets of clamping mechanisms are rotatably connected to both ends of the base 1 through the rotary bearing 2. Each set of clamping mechanisms includes a chuck body 3, a drive component 4, a sliding component 5, and a chuck 6. The two sets of chuck bodies 3 are fixedly connected to both sides of the inner ring of the rotary bearing 2. The drive component 4 is disposed inside the chuck body 3. The sliding mechanism is disposed on the side of the chuck body 3. The chuck 6 is disposed on the surface of the sliding component 5. The drive component 4 is disposed on the sliding component 5.

[0025] Each set of chuck bodies 3 corresponds to four sets of sliding components 5 and jaws 6, and the four sets of sliding components 5 and jaws 6 are arranged in a ring array with the axis of the chuck body 3 as the array center.

[0026] The drive assembly 4 includes a first synchronous gear ring 7, a second synchronous gear ring 8, a cylinder 9, a push shaft 10, and a synchronous pinion 11. The first synchronous gear ring 7 and the second synchronous gear ring 8 are rotatably connected to the inner wall of the chuck body 3. The cylinder 9 is fixedly installed inside the chuck body 3. The push shaft 10 is fixedly installed at the output shaft end of the cylinder 9. The other end of the push shaft 10 is fixedly installed on the inner wall of the first synchronous gear ring 7. The synchronous pinion 11 is rotatably connected to the inside of the chuck body 3 and meshes with the inner walls of the first synchronous gear ring 7 and the second synchronous gear ring 8. The drive assembly 4 has four sets of cylinders 9, push shafts 10, and synchronous pinions 11. The four sets of cylinders 9, push shafts 10, and synchronous pinions 11 are arranged in a circular array with the axis of the chuck body 3 as the array center.

[0027] refer to Figure 1-5 In this embodiment, the drive assembly 4 also includes an air circuit module 12. There are two sets of air circuit modules 12. The two sets of air circuit modules 12 are respectively disposed between the inner walls of the two sets of chuck bodies 3 and the base 1. One end of the two sets of air circuit modules 12 passes through the two sets of chuck bodies 3 and is respectively disposed on the surface of the two sets of cylinders 9.

[0028] In the specific implementation, the air circuit module 12 is used to pre-compress air, and then rotate with the chuck body 3. When rotating, the external air inlet is separated from the air circuit module 12. Then the air circuit module 12 rotates with the chuck body 3 and inflates the cylinder 9 when needed, so that the cylinder 9 can be inflated even when it is in motion.

[0029] The sliding assembly 5 includes a track groove 51, a slider 52, and a toothed groove 53. The track groove 51 is fixedly installed on the surface of the chuck body 3. The slider 52 is slidably connected to the inside of the track groove 51. The toothed groove 53 is opened on the side of the slider 52. The chuck 6 is fixedly connected to the surface of the slider 52. One end of the synchronizing pinion 11 passes through the chuck body 3 and extends into the inside of the track groove 51 and meshes with the toothed groove 53.

[0030] refer to Figure 1-5 In this embodiment, the surface of the base 1 is provided with an installation groove 13, and a reducer 14 is fixedly installed inside the installation groove 13. A drive wheel 15 is fixedly installed at the output shaft end of the reducer 14. A driven gear 16 is fixedly sleeved on the side of a set of chuck bodies 3, and the driven gear 16 meshes with the drive wheel 15.

[0031] In practice, when the reducer 14 starts, it drives the driven gear 16 to rotate through the drive wheel 15. The rotation of the driven gear 16 drives a set of chuck bodies 3 to rotate on the slewing bearing 2, and then drives another set of chuck bodies 3 to rotate through the slewing bearing 2.

[0032] refer to Figure 1-5 In this embodiment, the number of jaws 6 is matched with the number of chuck bodies 3. One set of jaws 6 is a hard jaw 6, and the other set of jaws 6 is a roller jaw 6.

[0033] In practice, different types of jaws 6 are used to clamp different components, and the clamping efficiency is further improved by changing the jaws 6. Each jaw 6 is composed of a base jaw and a top jaw. By changing the top jaw, the functions of a positive jaw and a negative jaw are achieved. Here, the inner wall and side of the jaw 6 have clamping functions.

[0034] The working principle of this utility model is as follows:

[0035] When the laser-powered chuck is working, the air circuit module 12 delivers compressed air to the cylinder 9 inside the chuck body 3. The piston rod of the cylinder 9 extends and pushes the push shaft 10 fixed thereto to move. The push shaft 10 drives the first synchronous gear ring 7 fixed thereto to rotate. The first synchronous gear ring 7 drives multiple synchronous pinions 11 meshing with it to rotate. The synchronous pinions 11 mesh with the second synchronous gear ring 8 at the same time, thereby driving the second synchronous gear ring 8 to rotate synchronously. The other end of the synchronous pinion 11 passes through the chuck body 3 and meshes with the tooth groove 53 on the side of the slider 52, thereby converting the rotational motion into the radial linear motion of the slider 52, so that the slider 52 moves inside the track groove 51. The four sets of sliders 52 distributed in a ring array slide synchronously radially in the track groove 51, driving the chuck 6 fixed on its surface to move synchronously radially, realizing the clamping or loosening of the workpiece.

[0036] When the workpiece needs to be rotated, the reducer 14 drives the drive wheel 15 to rotate. The drive wheel 15 meshes with the driven gear 16 fixed on the side of a set of chuck bodies 3, driving the entire chuck mechanism (fixed to the chuck body 3 through the inner ring of the slewing bearing 2) and the clamped workpiece to rotate around the axis of the base 1, meeting the power requirements of laser processing. Throughout the process, the chuck mechanisms at both ends of the base 1 rotate synchronously through the slewing bearing 2, completing the composite function of double-sided separate clamping and power rotation.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
