Description

Technical Field

[0001] The utility model relates to the technical field of saw blade processing, and more specifically to a base saw blade positioning turntable of a saw blade laser welding machine. Background Art

[0002] The base saw blade positioning turntable of the saw blade laser welding machine is a positioning and rotating device used for welding saw blades. It is used to manufacture or repair saw blades to ensure the quality and performance of the saw blades. The positioning turntable can fix the saw blade in a suitable position to ensure the accuracy and consistency of the welding position.

[0003] Chinese patent authorization announcement number: CN219598533U provides a saw blade welding fixing device. This solution uses a fixing frame, a threaded fixing rod, a clamping fixing plate, a conical limiting bolt, a reverse threaded rod and a clamping rod and other components in coordination, so that the saw blade welding fixing device can first use the conical limiting bolt to initially limit and fix the saw blade during use. At the same time, the conical limiting bolt can also be well adapted to saw blades with mounting holes of different sizes. The saw blade is then clamped and fixed for a second time through the clamping rod, and the friction between the saw blade and the anti-slip rubber pad is used to increase the friction between the saw blade and the saw blade while protecting the saw blade, thereby effectively improving the stability of the saw blade welding fixing device for fixing the saw blade.

[0004] When welding a saw blade, each tooth of the saw blade needs to be welded with a material with higher hardness such as diamond or tungsten steel. The device in the above scheme can only fix the saw blade. Therefore, each time a saw tooth is welded, it needs to be loosened, rotated and then clamped. The operation is cumbersome, which reduces production efficiency and is inconvenient to use. Therefore, in view of the above problem, a base saw blade positioning turntable of a saw blade laser welding machine is proposed. Utility Model Content

In order to increase the strength of the saw blade teeth, a small piece of tungsten steel or other hard material is usually welded on the saw teeth. The saw blade laser welding machine is a device that uses laser technology to weld saw blades. It uses a laser beam to heat and melt the saw teeth and welding materials to weld them together.

[0038] The device is mainly fixed by tightening the inner ring of the saw blade through the outwardly expanded abutment block 64, and the abutment block 64 is mainly driven by the driving disk 61, and the driving disk 61 is rotated by the rotation of the worm gear 53. The fixed disk 62 is fixed to the outside of the turntable 7, and the other side of the turntable 7 is fixed with a rotating shaft 8, which passes through the top of the workbench 2 and is connected to the output end of the servo motor 3, so as to achieve the purpose of outputting power to make the turntable 7 drive the fixed component 6 to rotate, so that the fixed saw blade can be rotated to complete the welding of each saw tooth.
