Description

Technical Field

[0001] The invention relates to the technical field of laser welding, in particular to a positioning tool for laser welding. Background Art

[0002] During the welding process, the object to be welded must first be positioned, and then the welding machine can be used for welding. The existing positioning tooling for laser welding machines has the following shortcomings: during welding, if the operator does not clamp the object to be welded, it is easy for the object to be irradiated by the laser and deviate during welding, which can easily lead to waste. At the same time, welding slag will fall onto the welding operation surface during welding, which needs to be cleaned. Manual cleaning consumes manpower, and the operator is distracted by cleaning, which can easily affect the subsequent welding work.

[0003] After searching the Chinese patent with publication number CN219944936U, a positioning tool for a laser welding machine is disclosed. By setting a rotating handle to drive the rotating rod to push the clamp forward, the gas support rod and the adjusting screw are used to fix the clamp, so as to realize the clamping and positioning of the welding object during laser welding, avoid the welding object from being offset during laser welding and causing welding failure, and play a role in stabilizing welding; a lifting plane is set to cooperate with the support roller at the bottom to rotate and then cooperate with a cleaner for cleaning, so as to realize automatic cleaning of welding slag generated during welding, eliminate manual cleaning, save labor, and avoid welding slag affecting subsequent welding work.

[0004] Based on the above search and combined with the prior art, it was found that two clamps are generally used to clamp and fix the workpiece during laser welding. There is no corresponding limiting structure at other positions of the workpiece, and the stability in other directions is poor. The workpiece is still easily offset by external forces during welding, resulting in welding failure. The clamping structure cannot automatically lock after clamping, the positioning function is poor, the processing error increases, and repeated positioning is inaccurate, which reduces the positioning efficiency of the laser welding positioning tooling.

[0036] Further, the outer wall of the bottom end of the support net frame 6 is fixedly connected with a support tube 25, the outer walls of both sides of one side of the bottom of the clamping frame 16 are installed with air bags 15, the outer wall of one side of the air bag 15 is fixedly connected with the fixing plate 14, the support rod 17 is fixedly connected to the outer wall of the top of the fixing plate 14, the outer wall of the bottom end of the air bag 15 is provided with an air port, the inner wall of the air port is plugged with a hose 9, the four corners of the outer wall of the top of the platform 1 are provided with connecting holes, the hose 9 is fixedly connected to the inner wall of the connecting hole, the outer wall of one side of the support tube 25 is provided with an air inlet 28, the air inlet 28 is connected to the connecting hole, and the outer walls of both sides of the support tube 25 are provided with a plurality of air outlets 27, the air outlets 27 are all distributed in a linear array, and the air outlets 27 are all inclined. The platform 1 is arranged obliquely, and a feed plate 26 is fixedly connected to the bottom inner wall of the platform 1. The outer walls on both sides of the top of the feed plate 26 are provided with inclined surfaces, and the air outlet 27 is adapted to the size of the inclined surfaces. A slag discharge hole is opened on the outer wall of the bottom end of the platform 1, and the slag discharge hole is adapted to the size of the feed plate 26. A control panel is installed on the outer wall of the platform 1, and the control panel is electrically connected to the motor 2. The airflow ejected through the air outlet 27 hits the inclined surface of the feed plate 26 to clean up the stubborn residual welding slag, further increasing the cleaning effect. The airbag 15 is connected to the support rod 17, so that the speed of the clamp 7 is slowed down when it is reset under the action of the reset spring 18, thereby reducing the wear caused by the impact during reset and increasing the service life of the clamping structure.

[0037] Working principle: During the laser welding process, the workpiece to be processed is placed on the supporting mesh frame 6 of the platform 1, and the motor 2 is started to control the rotation of the bidirectional screw 10, thereby controlling the two sliding frames 5 to close, and the clamping frame 16 on the sliding frame 5 also approaches. The two clamping plates 7 first contact the two sides of the workpiece. As the sliding frame 5 continues to approach, the clamping plate 7 presses the support rod 17 and the reset spring 18 to approach the clamping frame 16 until the clamping plate 7 contacts the inner wall of the clamping frame 16, and the reset spring 18 is completely contracted. The clamping plate 7 clamps and fixes the workpiece from both sides. When the clamping plate 7 approaches the clamping frame 16, it pushes the bottom plate 21 at the bottom of the limit plate 8, causing it to rotate under the action of the rotating shaft 30 inside the bracket 19, and the limit plate 8 is rotated. The plate 8 also rotates to be horizontal, and limits the top corner of the workpiece from the top, further increasing the positioning effect. When the limit plate 8 rotates to be horizontal, the arc block 20 at the top of the limit plate 8 also rotates accordingly, and the arc block 20 is in contact with the locking plate 11 of the locking frame 4 to support it. When the limit plate 8 is horizontal, the arc block 20 is just separated from the locking plate 11, and the locking frame 4 drives the locking plate 11 and the locking rod 24 to slide down on the clamping frame 16 under the action of gravity. The locking plate 11 is inserted into the L-shaped rod 22 on one side of the bracket 19 for locking, and the locking rod 24 is inserted into the locking hole 29 of the support rod 17 for locking. The clamp 7 and the limit plate 8 are locked and will not loosen, further enhancing the positioning function.

[0038] When the laser welding is completed and the workpiece needs to be removed, the motor 2 controls the bidirectional screw 10 to rotate in the opposite direction, and the sliding frame 5 is separated. At this time, the clamping structure on the clamping frame 16 is still locked to ensure that the workpiece will not be deviated by the reset spring 18 and the clamping plate 7. The locking frame 4 on the clamping frame 16 is close to the pressing plate 23 of the magnetic plate 3 until the pressing plate 23 contacts the inclined groove of the pressure plate 12. The sliding frame 5 continues to move, and the pressing plate 23 cooperates with the inclined groove of the pressure plate 12 to make the locking frame 4 rise and reset. The support rod 17 and the L-shaped rod 22 are unlocked and released, and the limit plate 8 is also reset under the action of the torsion spring on the rotating shaft 30. The clamping plate 7 is reset accordingly under the action of the reset spring 18. The clamping frame 16 can slide up and down on the outer wall of the sliding frame 5 and be fixed by the locking knob 13, which is convenient for adjusting the position according to the height of the workpiece to ensure that the limit plate 8 just contacts the top corner of the workpiece for limiting after rotation.

[0039] The airbag 15 is connected to the support rod 17 on one side through the fixing plate 14. Each time the clamping plate 7 clamps the outer wall of the workpiece, the distance between the fixing plate 14 and the clamping frame 16 increases, and the airbag 15 is stretched. When the clamping plate 7 is reset under the action of the reset spring 18, the airbag 15 is compressed accordingly, and the air enters the platform 1 through the hose 9, and then enters the support tube 25 through the connecting hole and the air inlet 28, and finally is ejected through the inclined air outlet 27. The workpiece is placed on the support mesh frame 6 of the platform 1. The welding slag dropped during laser welding directly falls on the blanking plate 26 through the supporting mesh frame 6, and is discharged through the inclined surface on the blanking plate 26. The airflow ejected through the air outlet 27 hits the inclined surface of the blanking plate 26, and the stubborn residual welding slag is cleaned, further increasing the cleaning effect. The airbag 15 is connected to the support rod 17, and the speed of the clamping plate 7 when it is reset under the action of the reset spring 18 is slowed down, reducing the wear caused by the impact during resetting, and increasing the service life of the clamping structure.
