Description

Technical Field

[0001] The invention relates to the field of saw blade welding equipment, in particular to a saw blade processing laser welding device. Background Art

[0002] Circular saw blades are a common cutting tool. Commonly used saw blades are mostly made of steel sheets cut into saw blade bodies, and the blade heads are welded on the sawtooth surfaces around the saw blades. In the prior art, the blade heads are welded by brazing and laser welding. Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. In the prior laser welding process, the saw blade is placed horizontally and irradiated with laser from top to bottom to weld it. However, the prior welding method cannot quickly cool the welding point after welding.

[0003] According to the patent document with the existing publication number CN217799583U, a double-head irradiation laser welding device for circular saw blades is disclosed, which includes a base plate, a second cylinder is fixedly connected to the upper surface of the base plate, a U-shaped frame is fixedly connected to the driving end of the second cylinder, laser welding heads are fixedly connected to the upper parts of both ends of the U-shaped frame, and adjusting feet are installed at the four corners of the base plate, a vertical plate is fixedly connected to the upper surface of the base plate, a first cylinder is fixedly connected to the upper right surface of the vertical plate, and a first fixed plate is fixedly connected to the lower surface of the fixed end of the first cylinder. When using this technical solution, the two laser welding heads are used to complete the welding of the cutter head from both sides, thereby reducing the cold welding caused by uneven heating and improving the welding strength between the circular saw blade and the cutter head. With respect to the above technical solution, although this solution increases the welding strength, it is impossible to perform multi-point limit support on the saw blade during welding, and it is impossible to dissipate heat and cool down during support, which is inconvenient when used.

[0029] In this embodiment, a pushing mechanism 9 is fixed on the support seat 3, and a connecting plate 25 is fixed on one end of the pushing mechanism 9, and one end of the connecting plate 25 is welded to the exhaust cylinder 10. A cavity is opened inside the fixed seat 2, and a driving motor 33 and a lifting mechanism 34 are fixedly installed inside the cavity. The lifting mechanism 34 is fixedly installed on the side of the driving motor 33, and a fixing ring 12 is fixed on one end of the lifting mechanism 34. A rotating ring 13 is rotatably installed on the fixing ring 12, and a convex ring is fixed on the inner wall of the rotating ring 13. A ring groove is opened on the fixing ring 12, and the convex ring is rotatably installed inside the ring groove. A rotating disk 14 is movably installed between the rotating rings 13. The pushing mechanism 9 and the lifting mechanism 34 are both linear reciprocating electric push rods. The pushing mechanism 9 pushes the exhaust cylinder 10 to adjust the upper and lower positions, and the lifting mechanism 34 pushes the rotating ring 13 and the fixing ring 12 to adjust the heights. The up and down movement of the exhaust cylinder 10 completes the limit fixation of the center point of the saw blade 29.

[0030] In this embodiment, the rotating disk 14 is fixedly installed on the driving motor 33, and a fixing groove 15 is opened on the rotating disk 14. A protrusion 32 is movably installed inside the fixing groove 15, and a fixing column 16 is fixed on the protrusion 32. The fixing column 16 is installed inside the fixing groove 15 through a supporting mechanism 17. A mounting groove 18 is opened on the fixing column 16, and a limiting column 19 is movably installed inside the mounting groove 18. A fixing block 21 is fixed on the limiting column 19, and the fixing block 21 is movably installed inside the mounting groove 18. A limiting groove 20 is opened on the inner wall of the mounting groove 18, and a limiting block 22 is movably installed inside the limiting groove 20. The supporting mechanism 17 is a supporting spring, and the supporting spring pushes the fixing column 16 to enter one end of the heat dissipation groove 30, so that multi-point limiting support for the saw blade 29 is achieved through the fixing column 16.

[0031] In this embodiment, a reset mechanism 24 is fixed on the limit block 22, one end of the reset mechanism 24 is fixed inside the limit groove 20, the limit block 22 and the fixed block 21 are connected by a reset shaft 23, a rotating seat 26 is rotatably installed at the bottom of the exhaust tube 10, an opening 27 is opened on the rotating seat 26, an exhaust fan 28 is fixedly installed inside the exhaust tube 10, a saw blade 29 is movably installed on the rotating disk 14, a heat dissipation groove 30 is opened on the saw blade 29, the heat dissipation groove 30 is movably matched with the fixed column 16, a cutter head 31 is adsorbed and installed on the rotating ring 13, and the cutter head 31 is installed on the side of the saw blade 29, the reset mechanism 24 is a reset spring, the service spring pushes the limit column 19 to move downward, and the limit column 19 realizes the upper and lower limit of the saw blade 29 after being parallel to the saw blade 29.

[0032] When the device is in use, the saw blade 29 is first installed on the fixed column 16. Before the saw blade 29 is installed, the limit column 19 drives the fixed block 21 to move upward. After the fixed block 21 moves upward, it provides the required space for the rotation of the limit column 19. After the limit column 19 rotates, it shrinks inside the installation groove 18. The saw blade 29 is installed on the rotating disk 14 through the limit column 19 and the fixed column 16. The limit column 19 is loosened, and the reset shaft 23 drives the limit column 19 to rotate 90 degrees and then be perpendicular to the saw blade 29. Under the push of the reset mechanism 24, the limit column 19 moves to the top of the saw blade 29. The limiting column 19 realizes the upper and lower limiting of the saw blade 29. The fixed column 16 moves to one end of the heat dissipation groove 30 under the push of the support mechanism 17. The fixed column 16 provides multi-point limiting support for the saw blade 29. The cutter head 31 is installed on the rotating ring 13. One end of the cutter head 31 contacts the side of the saw blade 29. When the cutter head 31 and the saw blade 29 are aligned, the lifting mechanism 34 is started to control the up and down movement of the fixed ring 12 and the rotating ring 13. Under the push of the rotating ring 13, the cutter head 31 contacts the saw blade 29 at different positions. After the position of the cutter head 31 is determined, the fixed column 16 is started. The electromagnet inside the ring 12 generates suction, which is transmitted to the rotating ring 13. The rotating ring 13 adsorbs and fixes the cutter head 31. After the cutter head 31 is fixed, the displacement mechanism 5 and the adjustment mechanism 8 are started to adjust the position of the laser welding head 11 up, down, left and right. The laser welding head 11 moves to the contact point between the cutter head 31 and the saw blade 29 for welding. During welding, the pushing mechanism 9 is started. The pushing mechanism 9 pushes the exhaust cylinder 10 to move downward. After the exhaust cylinder 10 moves downward, the rotating seat 26 contacts the center point of the saw blade 29, and the rotating seat 26 completes the extrusion and fixation of the saw blade 29. After the welding of the cutter head 31 at a position is completed, the saw blade 29 transmits the rotational force to the rotating ring 13 through the cutter head 31, and the driving motor 33 is started to drive the rotating disk 14 to select. When the rotating disk 14 selects, the cutter head 31 after welding drives the rotating ring 13 to rotate on the fixed ring 12, and the cutter head 31 changes position as the saw blade 29 rotates. The circular welding of the cutter head 31 and the saw blade 29 is completed through the rotation of the rotating disk 14. During welding, the exhaust fan 28 draws air downward, and the airflow is sprayed to the welding point through the opening 27, so as to quickly cool the welding point.
