Description
Technical Field
[0001] This utility model relates to laser welding machines, and more particularly to a laser welding machine capable of rotating workpieces. Background Technology
[0002] A laser welding machine is a device that uses a high-energy-density laser beam as a heat source for welding. It focuses the laser beam on the joint of the materials to be welded, causing the local area to heat up rapidly to a molten state, thereby achieving a strong connection between the materials.
[0003] When the welding position is circular, the welding positions of the two workpieces are aligned and limited so that they cannot move. Then, the welding module of the welding machine can be rotated to complete the welding between the workpieces. However, the rotation of the laser head or welding assembly can easily cause positioning errors, which will affect the welding accuracy and stability. At the same time, rotating the laser head or welding assembly may cause the fiber optic connection part of the laser head to bear additional stress or torque, which will affect its service life.
[0004] Therefore, how to achieve the rotation of the workpiece mounting position on the laser welding machine has become a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a laser welding machine that can rotate workpieces by driving a first mounting base and a second mounting base containing a first workpiece and a second workpiece to rotate through a cooperating module.
[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a worktable and a laser head, the laser head being located above the worktable. A first workpiece is disposed on the left side of the laser head, and a second workpiece is disposed on the right side of the laser head. It also includes a first mounting base and a second mounting base on the worktable, a first adjusting component located on the left side of the laser head for housing the first mounting base, a second adjusting component located on the right side of the laser head for housing the second mounting base, and a cooperating module for rotating the first and second mounting bases. The first mounting base is provided with several locking components for locking the first workpiece. The second mounting base has the same shape and size as the first mounting base, and the second adjusting component has the same shape and size as the first adjusting component.
[0007] The present invention is further configured such that: the first adjustment component includes a drive cylinder, an adjustment plate linked with the drive cylinder, a mounting plate for the drive cylinder to be installed, adjustment rods fixedly installed on the upper and lower sides of the adjustment plate, and swing arms linked with each adjustment rod. The front side of the mounting plate is fixedly installed on the linkage plate, and one end of each swing arm is rotatably connected to the linkage plate.
[0008] The present invention is further configured such that: each locking component is a bolt, and each positioning component on the first mounting base is provided with a screw hole, and each positioning component is inserted into a screw hole and abuts against the first workpiece in the circumferential direction.
[0009] The present invention is further configured such that: the first mounting base is provided with a first mating tooth in the circumferential direction, the second mounting base is provided with a second mating tooth in the circumferential direction, the mating module includes a first transmission wheel that is linked with the first mating tooth, a second transmission wheel that is driven by the second mating tooth, and a drive group that makes the first transmission wheel and the second transmission wheel rotate synchronously, the first transmission wheel is provided with a third meshing tooth that meshes with the first mating tooth, and the second transmission wheel is provided with a fourth meshing tooth that meshes with the second mating tooth.
[0010] The present invention is further configured such that: the drive assembly includes a drive rod with a first drive wheel and a second drive wheel inserted therein, and a turntable fixed to the drive rod; the drive rod is fixed to the first drive wheel and the second drive wheel and is rotatably mounted on the worktable.
[0011] The present invention is further configured such that: the workbench includes a mating plate on the right side and a disassembly plate, the first transmission wheel and the second transmission wheel are both located inside the mating plate and the disassembly plate is rotatably connected to the transmission rod, and the disassembly plate is detachably connected to the mating plate.
[0012] The present invention is further configured such that the turntable is provided with a plurality of contact grooves in its circumferential direction.
[0013] By adopting the above technical solution, the first and second cylindrical workpieces to be welded are placed in the corresponding first and second mounting seats, respectively. Then, the locking components ensure that the first workpiece is stably positioned in the first mounting seat and the second workpiece is stably positioned in the second mounting seat. At this time, the cooperating module can drive the first and second mounting seats to rotate. As the first and second mounting seats rotate, the first and second workpieces can also rotate. At this time, the laser head located directly above the welding position of the first and second workpieces is activated. As the first and second workpieces rotate, circumferential welding of the first and second workpieces can be achieved. After the welding of the first and second workpieces is completed, the locking components can be released by applying force in opposite directions, and the welded first and second workpieces can be removed.

[0026] 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.
[0027] like Figures 1-6 As shown, this utility model discloses a laser welding machine capable of rotating workpieces, including a worktable 1 and a laser head 2 (the working principle and structure are prior art, and the figure is for illustrative purposes only). The laser head 2 is located above the worktable 1. A first workpiece 111 is arranged on the left side of the worktable 1, and a second workpiece 121 is arranged on the right side of the laser head 2. By placing the position where the first workpiece 111 and the second workpiece 121 need to be welded below the laser head 2 and then activating the laser head 2, the first workpiece 111 and the second workpiece 121 can be welded together. The welding process also includes a first mounting base 11 and a second mounting base 12 located on the worktable 1, a first adjusting component 3 located on the left side of the laser head 2 for mounting the first mounting base 11, a second adjusting component 4 located on the right side of the laser head 2 for mounting the second mounting base 12, and a mating module 5 for rotating the first mounting base 11 and the second mounting base 12. The first mounting base 11 is provided with a plurality of locking parts 112 for locking the first workpiece 111. The second mounting base 12 is the same shape and size as the first mounting base 11. The second adjusting component 4 and the first mounting base 11 are mated to rotate. The adjustment components 3 are of the same shape and size. The first cylindrical workpiece 111 and the second cylindrical workpiece 121 to be welded are placed into their respective first mounting base 11 and second mounting base 12. Then, the locking member 112 ensures that the first workpiece 111 is stably positioned in the first mounting base 11 and the second workpiece 121 is stably positioned in the second mounting base 12. At this time, the mating module 5 can drive the first mounting base 11 and the second mounting base 12 to rotate. As the first mounting base 11 and the second mounting base 12 rotate, the first workpiece 111 and the second cylindrical workpiece 121 are also rotated. When the second workpiece 121 rotates, the laser head 2, located directly above the welding position of the first workpiece 111 and the second workpiece 121, is activated. As the first workpiece 111 and the second workpiece 121 rotate, circumferential welding of the first workpiece 111 and the second workpiece 121 can be achieved. After the welding of the first workpiece 111 and the second workpiece 121 is completed, the locking of the first workpiece 111 and the second workpiece 121 can be released by applying force in opposite directions to each locking member 112, thereby removing the first workpiece 111 and the second workpiece 121 that are welded together.
[0028] The first adjustment component 3 includes a drive cylinder 31 (this is prior art and will not be described in detail here), an adjustment plate 32 linked to the drive cylinder 31, a mounting plate 33 for the drive cylinder 31 to be installed, adjustment rods 34 fixedly installed on the upper and lower sides of the adjustment plate 32 by bolts or other means, and swing arms 35 linked to each adjustment rod 34. The front side of the mounting plate 33 is fixedly installed to the linkage plate 36 by welding or other means. One end of each swing arm 35 is rotatably connected to the linkage plate 36. After the drive cylinder 31 is started, the adjustment plate 32 moves back and forth as the output shaft of the drive cylinder 31 moves, and the adjustment plate 32 moves forward and backward as it moves. Each adjusting rod 34 moves, thereby causing the connection position of each swing arm 35 with the corresponding adjusting rod 34 to move back and forth. Since each swing arm 35 is rotatably connected to the linkage plate 36, each swing arm 35 can change its rotation angle as the drive cylinder 31 works, thus enabling it to cooperate with the first mounting base 11 of different diameters. When each swing arm 35 is in contact with the upper and lower ends of the first mounting base 11, the work of the drive cylinder 31 is paused, thereby causing each swing arm 35 to clamp the first mounting base 11 and prevent it from moving. Thus, when the first workpiece 111 is installed into the first mounting base 11, the first mounting base 11 can be stably positioned between the upper and lower swing arms 35.
[0029] Each locking component 112 is a bolt. Each positioning component on the first mounting base 11 is provided with a screw hole 113. Each positioning component is inserted into the screw hole 113 and abuts against the first workpiece 111 in the circumferential direction. When the locking component 112 (i.e. the bolt) is tightened, its end will apply pressure to the first workpiece 111 inside, increasing the friction between the two, thereby preventing the first workpiece 111 inside from moving relative to the first mounting base 11. Reverse rotation of the locking component 112 can make its end move away from the first workpiece 111, thereby facilitating the removal of the first workpiece 111 from the first mounting base 11.
[0030] The first mounting base 11 is circumferentially provided with a first mating tooth 114, and the second mounting base 12 is circumferentially provided with a second mating tooth 122. The mating module 5 includes a first transmission wheel 51 that is linked to the first mating tooth 114, a second transmission wheel 52 that is driven by the second mating tooth 122, and a drive group 53 that causes the first transmission wheel 51 and the second transmission wheel 52 to rotate synchronously. The first transmission wheel 51 is provided with a third meshing tooth 511 that meshes with the first mating tooth 114, and the second transmission wheel 52 is provided with a fourth meshing tooth 521 that meshes with the second mating tooth 122. Because the drive group 53 can be activated... The first transmission wheel 51 and the second transmission wheel 52 are driven to rotate, so that the third meshing teeth 511 and the fourth meshing teeth 521 on the first transmission wheel 51 and the second transmission wheel 52 can mesh with the first mating teeth 114 on the first mounting base 11 and the second mating teeth 122 on the second mounting base 12, respectively. This allows the first workpiece 111 and the second workpiece 121 to rotate as the first mounting base 11 and the second mounting base 12 rotate, thereby enabling the laser head 2 to perform circumferential welding on the welding position of the first workpiece 111 and the second workpiece 121.
[0031] The drive assembly 53 includes a drive rod 531 with a first drive wheel 51 and a second drive wheel 52 inserted therein, and a turntable 532 fixed to the drive rod 531 by welding or other means. The drive rod 531 is fixed to the first drive wheel 51 and the second drive wheel 52 by welding or other means and is rotatably mounted on the worktable 1. Since the drive rod 531 is fixedly connected to the turntable 532 and is rotatably mounted on the worktable 1, applying torque to the turntable 532 can drive the drive rod 531 to rotate, thereby causing the first drive wheel 51 and the second drive wheel 52 located on the drive rod 531 to rotate synchronously, thereby driving the first mounting base 11 and the second mounting base 12 to rotate.
[0032] The workbench 1 includes a mating plate 14 on the right and a disassembly plate 13. The first transmission wheel 51 and the second transmission wheel 52 are both located inside the mating plate 14, and the disassembly plate 13 is rotatably connected to the transmission rod 531. The disassembly plate 13 and the mating plate 14 are detachably connected by fastening, bolts, etc. Since the transmission rod 531 is rotatably installed inside the disassembly plate 13, after the disassembly plate 13 is removed from the mating plate 14, the transmission rod 531, as well as the first transmission wheel 51 and the second transmission wheel 52 fixed on the transmission rod 531, can be installed, and then the disassembly plate 13 and the mating plate 14 can be fixed to facilitate the installation of the drive assembly 53.
[0033] Preferably, the turntable 532 is provided with a plurality of contact grooves 5321 in the circumferential direction. The presence of the plurality of contact grooves 5321 can effectively improve the roughness of the turntable 532 in the circumferential direction, thereby increasing the circumferential friction and reducing the slippage between the hand or operating tool and the turntable 532 when torque is applied to the turntable 532. In addition, compared with the direct rotation of the transmission rod 531 by a motor or other driving component, manual rotation can more directly control the rotation speed of the first mounting base 11 and the second mounting base 12 and can adjust the rotation angle of the turntable 532 as needed.
[0034] It is worth noting that the second mounting base 12 is the same as the first mounting base 11, and the second adjustment component 4 is the same as the first adjustment component 3, so they will not be described in detail here.
[0035] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
