Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a clamping device for ultra-thin laser welding processing. Background Technique

[0002] Laser welding is an efficient and precise welding method that uses a laser beam with a high energy density as a heat source. Laser welding is one of the important applications of laser material processing technology, mainly used for welding thin-walled materials and low-speed welding. The welding process belongs to the heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses inward through heat conduction. By controlling parameters such as the width, energy, peak power, and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool. Due to its unique advantages, it has been successfully applied to the precision welding of micro and small parts.

[0003] The existing patent (Publication No.: CN113967805B) discloses a clamping device for laser welding of ultra-thin metal plates. A material to be welded is placed between the clamping part and the support plate. The top of the triangular thrust plate is movably connected with a movable top plate. The top surface of the movable top plate abuts against an elastic ejector rod mechanism, and the elastic ejector rod mechanism abuts against the back protection backing plate. The movable top plate jacks up the elastic ejector rod mechanism, and the elastic ejector rod mechanism jacks up the back protection backing plate to provide an elastic clamping force for the metal bipolar plate to prevent the metal bipolar plate from sagging. In the process of implementing this solution, it is found that the following problems exist in the prior art and have not been well solved:

[0004] Its structure is complex and the production cost is relatively high. Once a problem occurs, it is very difficult to carry out maintenance and part replacement work, and it is not suitable for large-scale promotion. Moreover, during the welding process, sometimes it is necessary to weld ultra-thin tubular materials, and it is difficult for this fixture to limit and clamp the tubular materials. Summary of the Utility Model

[0005] In order to improve the problems of complex structure and difficult maintenance mentioned above, and only being able to limit and fix ultra-thin metal tubes, the utility model provides a clamping device for ultra-thin laser welding processing.

[0006] The utility model provides a clamping device for ultra-thin laser welding processing, adopting the following technical scheme:

[0007] A clamping device for ultra-thin laser welding processing includes a device base (1) and a welding mechanism (2). A cylinder is arranged above the device base. A piston rod is connected inside the cylinder. The other side of the piston rod is connected with a limiting plate. Insertion rods are connected to both sides of the limiting plate. The other side of the insertion rods is connected with a linkage plate. Receiving blocks are connected to both sides of the linkage plate. A connecting rod is connected inside the receiving block. The other side of the connecting rod is connected with an adjusting rod;

[0008] One side of the adjusting rod is connected with a first anti-slip rod, the other side of the first anti-slip rod is connected with a first fixing block, a connecting spring is connected inside the first fixing block, a protective layer is connected outside the first fixing block, and a second fixing block is further arranged on the other side of the adjusting rod, and a second anti-slip rod is connected inside the second fixing block.

Moreover, the second fixing block is rotated to the lower part by the rotatable and adjustable linkage plate to clamp the tubular material, improving the adaptability.

The connection mode between the limit plate and the insertion rod is sliding connection, and the connection mode between the insertion rod and the linkage plate is threaded connection.

[0013] Through the above technical solution, it is convenient to connect and fix the linkage plate through the insertion rod to ensure that the linkage plate can continue to maintain stability after rotation.

The connection mode between the receiving block and the adjusting rod is sliding connection, the connection mode between the adjusting rod and the connecting rod is sliding connection, and the connecting rod penetrates through the receiving block and the adjusting rod.

[0015] Through the above technical solution, it is convenient to change the position of the adjusting rod through the cooperation of the linkage plate and the receiving block, so that the adjusting rod can be retracted when not in use.

[0016] Optionally, in the above clamping device for ultra-thin laser welding processing, the adjusting rod and the first fixing block form a spring reset structure through a connecting spring. The first fixing block is in a trapezoidal structure, and protective layers are evenly and equidistantly distributed below the first fixing block. The first fixing block and the adjusting rod form a sliding connection structure through the first anti-slip rod.

[0017] Through the above technical solution, it is convenient to complete the clamping and positioning of the ultra-thin metal plate by the cooperation of the first fixing block and the protective layer, and the first anti-slip rod is used for limiting to ensure the vertical lifting of the first fixing block.

[0018] Optionally, in the above clamping device for ultra-thin laser welding processing, the connection mode between the second fixing block and the second anti-slip rod is hot melt connection.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The following further elaborates on the present utility model in Figures 1-4 combination with the attached

[0029] Please refer to the drawings in the specification Figures 1-4, an embodiment provided by the present utility model: a clamping device for ultra-thin laser welding processing, including a device base 1 and a welding mechanism 2. A cylinder 3 is arranged above the device base 1. A piston rod 4 is connected to the inside of the cylinder 3. The other side of the piston rod 4 is connected to a limiting plate 6. The linkage plate 5 is conveniently adjusted through the limiting plate 6 to ensure subsequent use. Insertion rods 7 are connected to both sides of the limiting plate 6. The other side of the insertion rods 7 is connected to a linkage plate 5. Receiving blocks 8 are connected to both sides of the linkage plate 5. The length of the adjusting rod 9 is changed through the receiving blocks 8 to perform the clamping work. A connecting rod 10 is connected to the inside of the receiving block 8. The other side of the connecting rod 10 is connected to an adjusting rod 9;

[0030] A first anti-slip rod 11 is connected to one side of the adjusting rod 9. The other side of the first anti-slip rod 11 is connected to a first fixing block 12. The ultra-thin workpiece is assisted in fixing through the first fixing block 12. A connecting spring 14 is connected to the inside of the first fixing block 12. A protective layer 13 is connected to the outside of the first fixing block 12. A second fixing block 15 is also arranged on the other side of the adjusting rod 9. The tubular workpiece is fixed by using the second fixing block 15 to ensure subsequent use. A second anti-slip rod 16 is connected to the inside of the second fixing block 15.

[0031] Working principle: When in use, first, place the ultra-thin workpiece to be processed above the device base 1, and then turn on the switch of the cylinder 3, so that the cylinder 3 drives the linkage plate 5 to move through the piston rod 4. Thus, the first fixing block 12 also moves together. When the first fixing block 12 contacts the workpiece, due to its trapezoidal structure, the first fixing block 12 will squeeze the connecting spring 14 upward, so as to fit above the workpiece and complete the fixed processing work. Then, laser welding is performed through the welding mechanism 2;

[0032] As described above, when processing a tubular workpiece, first pull out the connecting rod 10, place the adjusting rod 9 on one side of the first fixing block 12 into the receiving block 8 and then reset the connecting rod 10. Then, pull out the adjusting rod 9 inside the second fixing block 15 according to the same steps, so that the second fixing block 15 moves to the front section. If the diameter of the workpiece is large, directly start the cylinder 3 so that the second fixing block 15 abuts against the inner wall of the workpiece twice. If the diameter of the workpiece is small and the second fixing block 15 is above the workpiece, then remove the piston rod 4 and rotate the linkage plate 5 so that the second fixing block 15 is below.

[0033] It should be added that cylinders 3 are symmetrically distributed on both sides above the device base 1. The connection mode between the cylinder 3 and the piston rod 4 is piston connection. The connection mode between the piston rod 4 and the limiting plate 6 is hot melt connection, which is convenient to drive the linkage plate 5 to move through the cooperation of the piston rod 4 and the limiting plate 6 to perform the limiting and fixing work.

[0034] It should be noted that the center of the limit plate 6 coincides with the center of the linkage plate 5. The connection mode between the limit plate 6 and the insertion rod 7 is a sliding connection, and the connection mode between the insertion rod 7 and the linkage plate 5 is a threaded connection. The linkage plate 5 is fixedly connected by the insertion rod 7 to ensure that the linkage plate 5 can remain stable after rotation.

[0035] It should be noted that receiving blocks 8 are symmetrically distributed on both sides of the linkage plate 5. The connection mode between the receiving block 8 and the adjusting rod 9 is a sliding connection, and the connection mode between the adjusting rod 9 and the connecting rod 10 is a sliding connection. The connecting rod 10 passes through the receiving block 8 and the adjusting rod 9. By cooperating with the linkage plate 5 and the receiving block 8, the position of the adjusting rod 9 is changed so that the adjusting rod 9 can be retracted when not in use.

[0036] It should be noted that the adjusting rod 9 and the first fixing block 12 form a spring return structure through the connecting spring 14. The first fixing block 12 is in a trapezoidal structure, and a protective layer 13 is evenly and equidistantly distributed below the first fixing block 12. The first fixing block 12 and the adjusting rod 9 form a sliding connection structure through the first anti-slip rod 11. The clamping and positioning of the ultra-thin metal plate are completed by the cooperation of the first fixing block 12 and the protective layer 13, and the first anti-slip rod 11 is used for limiting to ensure the vertical lifting of the first fixing block 12.

[0037] It should be noted that the connection mode between the second fixing block 15 and the second anti-slip rod 16 is a hot melt connection. The second fixing blocks 15 are symmetrically distributed on both sides of the center of the adjusting rod 9, and the second anti-slip rods 16 are staggered on both sides of the adjusting rod 9. The tubular workpiece is limited by the second fixing block 15 to improve the adaptability of the fixture.

[0038] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
