Description
Technical Field
[0001] This utility model relates to the field of mechanical manufacturing technology, specifically a novel laser-powered chuck with auxiliary hard claws. Background Technology
[0002] In modern manufacturing, laser processing technology has been widely used due to its high precision, high efficiency, and low material damage. As a crucial clamping device in laser processing equipment, the performance of the laser dynamic chuck directly affects processing accuracy, efficiency, and product quality. In recent years, with the manufacturing industry moving towards precision and diversification, more stringent requirements have been placed on the performance of laser dynamic chucks.
[0003] However, the traditional laser tube cutting machine, which requires chuck jaws for clamping, has the following problems:
[0004] 1. In laser tube cutting machines, due to the need for chucks and jaws to hold the workpiece, a small section of tail material is always left uncut during the final cutting of the workpiece, resulting in waste.
[0005] 2. When the chuck needs to perform the material pulling function, it is necessary to add a chuck and replace it with a hard chuck for clamping. When the material pulling function is not needed, cutting must be stopped for a long time, and the chuck must be retracted to a safe distance before cutting can begin.
[0006] To address the aforementioned problems, the inventors proposed a novel laser-powered chuck with auxiliary hard claws. Utility Model Content
[0007] In order to solve the problem of auxiliary clamping of laser-powered chucks, the purpose of this utility model is to provide a new type of laser-powered chuck with auxiliary hard claws.
[0008] To solve the above technical problems, the present invention adopts the following technical solution: a novel laser power chuck with auxiliary hard claws, comprising a base, on which a rotary bearing is provided, the outer ring of the rotary bearing being fixedly connected to the base, a chuck body being fixedly connected to one side of the inner ring of the rotary bearing, and the chuck body being fixedly connected to the side of the inner ring of the rotary bearing away from the synchronous gear ring, four sliders being slidably engaged at the top of the chuck body, the four sliders being centrally symmetrically distributed, and each slider having a mounting seat slidably engaged at its top, with rolling claws fixedly connected to the opposite side of each mounting seat, wherein a reset cylinder is fixedly mounted on the opposite side of two of the mounting seats, the piston rod of the reset cylinder extending to the inner side of the mounting seat and fixedly connected to an auxiliary claw, and the four sets of rolling claws forming a square interval.
[0009] Preferably, the chuck body is rotatably connected to a first synchronous gear ring and a second synchronous gear ring. A rack is fixedly connected to one side of each slider. A transmission gear is rotatably connected to the side of the chuck body near the rack. The transmission gear meshes with the corresponding rack. Two symmetrical rotary bearings mesh with the corresponding first synchronous gear ring and second synchronous gear ring respectively. Two cylinders are rotatably installed inside the base. The two cylinders are centrally symmetrically distributed. The piston rods of the cylinders are rotatably connected to the corresponding first synchronous gear ring and second synchronous gear ring respectively.
[0010] Preferably, a speed reducer is fixedly installed on one side of the base, a drive gear is fixedly connected to the drive end of the speed reducer, and a driven gear is fixedly connected to the side of the chuck body away from the synchronous gear ring, and the drive gear meshes with the driven gear ring.
[0011] Preferably, the top of the two symmetrically distributed rolling claws is provided with a locking plate, and the locking plate has two symmetrically distributed movable slots. The locking plate and the rolling claws are fixedly connected by a locking pin, and the locking pin is movably disposed in the movable slot.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. The hard jaw quick-change structure greatly shortens the conversion time between the chuck's conventional clamping and material pulling functions, making it suitable for continuous multi-process processing and improving equipment utilization.
[0014] 2. The length of the tail material is greatly reduced. The auxiliary hard jaws work together with the main jaws to hold the end section of the material. Combined with the laser cutting head to cut the over-cut, the length of the tail material is shortened and the material utilization rate is improved.
[0015] 3. No modification to the main structure of the chuck is required. It can be adapted to materials of different lengths simply by replacing the hard jaws and adjusting the auxiliary mechanism, making it compatible with most tubular metal material cutting scenarios. Attached Figure Description

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example: Figure 1-5 As shown, this utility model provides a novel laser power chuck with auxiliary hard claws, including a base 1, a rotary bearing 2 disposed on the base 1, the outer ring of the rotary bearing 2 being fixedly connected to the base 1, a chuck body 3 being fixedly connected to one side of the inner ring of the rotary bearing 2, and the chuck body 3 being fixedly connected to the side of the inner ring of the rotary bearing 2 away from the synchronous gear ring 9. Four sliders 4 are slidably engaged at the top of the chuck body 3, the four sliders 4 being centrally symmetrically distributed, and a mounting seat 5 being slidably engaged at the top of each slider 4. A rolling claw 6 is fixedly connected to the opposite side of each mounting seat 5, and a reset cylinder 7 is fixedly installed on the opposite side of two of the mounting seats 5. The piston rod of the reset cylinder 7 extends to the inner side of the mounting seat 5 and is fixedly connected to an auxiliary claw 8.
[0025] The chuck body 3 is internally connected to a synchronous gear ring 9 and a synchronous gear ring 10. A rack 11 is fixedly connected to one side of the slider 4. A transmission gear 12 is rotatably connected to the side of the chuck body 3 near the rack 11. The transmission gear 12 meshes with the corresponding rack 11. Two symmetrical rotary bearings 2 mesh with the corresponding synchronous gear ring 9 and synchronous gear ring 10 respectively.
[0026] By adopting the above technical solution, the first synchronous gear ring 9 and the second synchronous gear ring 10 respectively control the relative movement of two symmetrical rolling jaws 6. When the first synchronous gear ring 9 and the second synchronous gear ring 10 rotate, the first synchronous gear ring 9 and the second synchronous gear ring 10 are respectively connected by the meshing of the transmission gear 12, which drives the transmission gear 12 to rotate. The transmission gear 12 is connected by the meshing of the rack 11, which drives the sliders 4 to move radially, thereby adjusting the size of the opening between the sliders 4 and realizing the clamping operation of pipes with different diameters.
[0027] Two cylinders 15 are rotatably mounted inside the base 1. The two cylinders 15 are centrally symmetrically distributed, and the piston rods of the cylinders 15 are rotatably connected to the corresponding synchronous gear ring 9 and synchronous gear ring 10, respectively.
[0028] By adopting the above technical solution, the extension and retraction of the piston rod of cylinder 15 drives the corresponding synchronous gear ring 9 and synchronous gear ring 10 to rotate, thereby realizing the drive for the movement of the rolling chuck 6.
[0029] A reducer 19 is fixedly installed on one side of the base 1. A drive gear 13 is fixedly connected to the drive end of the reducer 19. A driven gear ring 14 is fixedly connected to the side of the chuck body 3 away from the synchronous gear ring 9. The drive gear 13 and the driven gear ring 14 are meshed together.
[0030] By adopting the above technical solution, the reducer 19 drives the drive gear 13 to rotate, and the drive gear 13 and the driven gear ring 14 mesh with each other, thereby driving the driven gear ring 14, the slewing bearing 2 and the slewing bearing 2 to rotate, thereby realizing the rotation of the workpiece.
[0031] The top of the two symmetrically distributed rolling claws 6 is provided with a locking plate 16. The locking plate 16 has two symmetrically distributed movable grooves 17. The locking plate 16 and the rolling claws 6 are fixedly connected by a locking pin 18, which is movably disposed in the movable groove 17.
[0032] By adopting the above technical solution, by loosening the locking pin 18, the locking pin 18 slides along the inside of the movable groove 17, adjusting the positional relationship between the front end of the clamping plate 16 and the front end of the rolling claw 6. When the front end of the clamping plate 16 exceeds the front end of the rolling claw 6, the rolling claw 6 becomes a hard clamping claw, realizing the conversion between conventional clamping and material pulling functions. The relative position of the rolling claw 6 and the clamping plate 16 is fixed by tightening the locking pin 18.
[0033] The four sets of rolling jaws form a square interval.
[0034] By adopting the above technical solution, a square interval is formed between the four sets of rolling jaws 6, which can be adapted to round and square pipes, further improving the applicability of the equipment.
[0035] Working principle: When cutting the pipe, the pipe is passed through the rolling jaws 6, and then the piston rod of the cylinder 15 extends, pushing the corresponding synchronous gear ring 9 and synchronous gear ring 10 to rotate. The synchronous gear ring 9 and synchronous gear ring 10 are respectively connected by the transmission gear 12, which drives the transmission gear 12 to rotate. The transmission gear 12 is connected to the rack 11, which drives the slider 4 to move radially towards each other, thereby adjusting the size of the opening between the sliders 4 and realizing the clamping operation of the pipe.
[0036] Furthermore, by extending the piston rod of the reset cylinder 7, the auxiliary chuck 8 is pushed to move radially toward one side closer to each other, forming a front-to-back coordinated clamping with the rolling chuck 6, independently and stably clamping the remaining material segment when processing the end of the pipe.
[0037] During processing, the reducer 19 drives the drive gear 13 to rotate. The drive gear 13 and the driven gear ring 14 mesh together, which in turn drives the driven gear ring 14, the slewing bearing 2 and the slewing bearing 2 to rotate, thereby realizing the rotation of the workpiece.
[0038] Meanwhile, the rolling jaw 6 adopts a quick-change hard jaw structure. By loosening the locking pin 18, the locking pin 18 slides along the inside of the movable groove 17, adjusting the positional relationship between the front end of the clamping plate 16 and the front end of the rolling jaw 6. When the front end of the clamping plate 16 exceeds the front end of the rolling jaw 6, the rolling jaw 6 becomes a hard clamp, realizing the conversion between conventional clamping and material pulling functions. The relative position of the rolling jaw 6 and the clamping plate 16 is fixed by tightening the locking pin 18.
[0039] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
