[0030] Such as Figures 1-6As shown in the figure, an embodiment of the present utility model provides a multi-size adjustment system for laser welding, which includes an adjustment mechanism 1 for adapting to the size of a welded metal frame. The adjustment mechanism 1 includes a bottom plate, two sets of side moving frames 14, and two sets of middle moving frames 15. The metal frame is fixed to the adjustment mechanism 1 through the two sets of side moving frames 14 and the middle moving frames 15 respectively. A plurality of clamping mechanisms are provided at the lower end of the metal frame, and the lower ends of the plurality of clamping mechanisms are respectively fixed at the side positions of the two sets of side moving frames 14, the two sets of middle moving frames 15, and the two sets of slide rails. Each of the plurality of clamping mechanisms includes a mounting seat 2 and a threaded sleeve 6. A cylinder 3 is fixedly installed at the upper end of the mounting seat 2. A raised thread is provided on the upper side wall of the cylinder 3. The inner wall of the threaded sleeve 6 is threadedly connected to the outer side wall of the cylinder 3 through the raised thread. A through groove 8 is opened at the upper end of the cylinder 3. Rotating shafts 10 are fixed at both ends of the inner wall of the through groove 8 close to the two ends. The side walls of the two rotating shafts 10 are rotatably connected with pressing members 9. The pressing members 9 are L-shaped. Raised portions are provided at the upper ends of the two pressing members 9 on the side close to each other. An inclined section is provided in the middle of the two pressing members 9 on the side close to each other. Straight sections are provided at the lower ends of the two pressing members 9 on the side close to each other. The included angle between the inclined end and the straight end is less than ninety degrees. A slope is provided on the side of the two pressing members 9 away from each other. Guide holes 7 are vertically penetrated through both sides of the cylinder 3 perpendicular to the two pressing members 9. A moving shaft 12 is slidably connected inside the guide holes 7. A pressing block 11 is rotatably connected to the outer wall of the moving shaft 12. The two sides of the pressing block 11 are symmetrical about the moving shaft 12, and the two raised portions at the lower end of the pressing block 11 are respectively in contact with the straight sections of the two pressing members 9. A limiting ring 13 for driving the moving shaft 12 to move upward is fixedly connected to the lower end of the inner wall of the threaded sleeve 6. Both ends of the moving shaft 12 are slidably connected to the lower end of the inner wall of the threaded sleeve 6. Two fixing bolts 5 are threadedly connected to the upper end of the mounting seat 2. Two folding angle elastic pieces 4 are fixedly installed on the upper end of the mounting seat 2 through the two fixing bolts 5 respectively. The two folding angle elastic pieces 4 are both L-shaped and have bent sections away from each other at the upper ends. The sides of the two folding angle elastic pieces 4 close to each other are respectively in contact with one side of the two pressing members 9. By rotating the threaded sleeve 6, the threaded sleeve 6 rotates downward along the raised thread on the cylinder 3. Due to the limiting effect of the guide holes 7, when the threaded sleeve 6 drives the limiting ring 13 to move downward, it slides downward along the inner wall of the guide holes 7. At this time, the pressing block 11 is driven by the moving shaft 12 to press the straight sections of the two pressing members 9 downward, further causing the lower ends of the two pressing members 9 to rotate away from the pressing block 11 around the rotating shafts 10. The two folding angle elastic pieces 4 cooperate to squeeze the lower ends of the pressing members 9 to generate elastic deformation, which plays a role in stabilizing the position of the pressing members 9. Further, the upper ends of the two pressing members 9 rotate closer to each other. The raised portions of the two pressing members 9 cooperate to squeeze the upper end of the metal frame, which plays a role in pressing the upper end of the metal frame, facilitating the multi-size adjustment system for laser welding. When the metal frame needs to be unloaded from the pressing mechanism after welding, the threaded sleeve 6 is rotated in the reverse direction, so that the threaded sleeve 6 rotates upward along the raised thread on the cylinder 3, and the two folding angle elastic pieces 4 recover their elastic deformation.At this time, the upper ends of the two sets of pressing members 9 rotate away from each other, and the protrusions of the two sets of pressing members 9 disengage from the metal frame rod portion, enabling a smooth overall blanking operation.

[0031] As Figures 1-6 shown, in this embodiment, anti-slip stripes for increasing friction and facilitating the rotation of the threaded sleeve 6 are provided on the outer wall of the threaded sleeve 6. The lower ends of the pressing block 11 and the two sets of pressing members 9 are both located in the through groove 8. In this embodiment, the widths of the pressing block 11, the pressing members 9, and the through groove 8 are all equal. The upper ends of the two sets of side moving frames 14 are fixedly installed with two sets of right-angle plates for fixing the four corners of the metal frame. Multiple sets of vertical plates for fixing the middle columns of the metal frame are fixedly installed on the two sets of middle moving frames 15. A bidirectional threaded rod is rotatably connected to the raised portion at the upper end of the bottom plate. One end of the bidirectional screw is fixedly connected to a rotating handle. The two sides with different thread rotation directions of the bidirectional screw are respectively threadedly connected to the lower ends of the two sets of side moving frames 14, and the two sides with different thread rotation directions of the bidirectional screw are respectively threadedly connected to the lower ends of the two sets of middle moving frames 15. Limiting slide rails are fixedly installed on both sides of the upper end of the bottom plate and on both sides of the bidirectional screw. The lower ends of the two sets of side moving frames 14 are slidably connected to the positions near the two ends of the two sets of limiting slide rails. The inner wall diameter of the threaded sleeve 6 is equal to the outer wall diameter of the cylinder 3. The metal frame is fixed on the two sets of side moving frames 14 through the four sets of right-angle plates, and then by rotating the rotating handle to drive the bidirectional screw to rotate, further driving the two sets of middle moving frames. 15 slide away from or close to each other along the two sets of limiting slide rails. Further, the middle columns of the metal frame can be driven to move by multiple sets of vertical plates and adjusted to a suitable welding position.

[0032] The technical solution provided by the present utility model fixes the metal frame on the two sets of side moving frames 14 through the four sets of right-angle plates, and then by rotating the rotating handle to drive the bidirectional screw to rotate, further driving the two sets of middle moving frames. 15 slide away from or close to each other along the two sets of limiting slide rails. Further, the middle columns of the metal frame can be driven to move by multiple sets of vertical plates and adjusted to a suitable welding position.

[0033] At this time, the metal frame rod is located between the two sets of threaded sleeves 6. By rotating the threaded sleeve 6, the threaded sleeve 6 rotates downward along the raised thread on the cylinder 3. Due to the limiting effect of the guiding hole 7, when the threaded sleeve 6 drives the limiting ring 13 to move downward, it slides downward along the inner wall of the guiding hole 7. At this time, the pressing block 11 is driven by the moving shaft 12 to press the straight sections of the two sets of pressing members 9 downward, further causing the lower ends of the two sets of pressing members 9 to rotate away from the pressing block 11 around the rotating shaft 10. The two sets of folding angle elastic pieces 4 cooperate to squeeze the lower ends of the pressing members 9 to generate elastic deformation, playing a role in stabilizing the position of the pressing members 9. Further, the upper ends of the two sets of pressing members 9 rotate closer to each other, and the protrusions of the two sets of pressing members 9 cooperate to squeeze the upper end of the metal frame, playing a role in pressing the upper end of the metal frame, facilitating a multi-size adjustment system for laser welding.

[0034] After welding is completed, when the metal frame needs to be unloaded from the clamping mechanism, the threaded sleeve 6 is rotated in the opposite direction to rotate upward along the raised thread on the cylinder 3, and the two groups of angled spring sheets 4 restore their elastic deformation. At this time, the upper ends of the two groups of clamping parts 9 rotate away from each other, and the protrusions of the two groups of clamping parts 9 are separated from the rod part of the metal frame, so that the overall unloading operation can be carried out smoothly.

[0035] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, the specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.

[0036] The above description is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention.
