DETAILED DESCRIPTION

[0013] The following will describe the implementation methods of the present invention in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0014] Please refer to Figure 1 and Figure 2 , Figure 1 is a three-dimensional diagram of a saw blade centering and positioning device according to an embodiment of the present invention; Figure 2It is a schematic diagram of the installation of a rotating magnetic disk according to an embodiment of the present invention. As shown in the figure, a saw blade centering positioning device is used for positioning and clamping and welding saw teeth, comprising: a base 10 for mounting a motor 11, the base 10 exposing a drive shaft 20, the drive shaft 20 being sleeved with a rotating magnetic disk 30 through a spline, and a guide sleeve 40 being sleeved on the front end of the drive shaft 20, the guide sleeve 40 being bolted to the rotating magnetic disk 30; a welding base 50 located at the front end of the rotating magnetic disk 30 and being able to move away from or approach; side clamping mechanisms 60 respectively located on both sides of the rotating magnetic disk 30 and being able to move away from or approach relatively; and an upper clamping mechanism 70 located at the upper end of the rotating magnetic disk 30 and being able to rise and fall; wherein the rotating magnetic disk 30 has a shock-absorbing hole 31 located on the outer ring and a top-feeding hole 32 located on the inner ring, and a mounting plate 80 is fixed to the rear side of the rotating magnetic disk 30 by bolts, and the mounting plate 80 has a top-feeding rod 81 and a rotation sensor 82 driven by a cylinder to be retracted in the top-feeding hole 32, and the rotation sensor 82 senses that the rotating magnetic disk 30 rotates one circle, and then drives the top-feeding rod 81 to protrude out of the top-feeding hole 32.

[0015] In one embodiment of the present invention, the base 10 is installed with a motor 11, and its driving shaft 20 is installed with a rotating magnetic disk 30 through a spline to drive the rotation, and a guide sleeve 40 is sleeved on the front end of the driving shaft 20 to facilitate the saw blade to be loaded and unloaded by the suction cup to avoid collision. The guide sleeve 40 is fastened to the rotating magnetic disk 30 by bolts and rotates therewith.

[0016] A reciprocating welding base 50 is provided at the front end of the rotating magnetic disk 30. The welding base 50 is mounted on the guide rail and has a positioning groove 51 for placing the saw blade teeth. The welding base 50 is driven by a cylinder to approach the rotating magnetic disk 30. The positioning groove 51 is carried on the lower side of the saw blade teeth, so that the saw teeth sent by the clamping are welded on the positioning groove 51. After the welding is completed, the cylinder can be used to drive the reset, and then the saw blade can be rotated to process the next tooth position.

[0017] At the same time, side clamping mechanisms 60 are respectively provided on both sides of the rotating magnetic disk 30, and an upper clamping mechanism 70 is provided on the upper end, which cooperates with the rotating magnetic disk 30 that is axially connected and adsorbed to achieve limited clamping on both sides and the upper part to enhance the stability during welding. Among them, the side clamping mechanism 60 drives the guide wheel 61 through the cylinder to clamp and adsorb on both sides of the saw blade of the rotating magnetic disk, and the guide wheel 61 slides and presses to avoid damaging the side surface of the saw blade. The upper clamping mechanism 70 drives the upper pressing rod 71 through the cylinder to press against the end of the saw blade adsorbed on the rotating magnetic disk 30, presses from the upper end, and cooperates with the guide wheel 61 to achieve multi-angle and multi-directional positioning clamping to enhance stability.

[0018] In addition, the rotating magnetic disk 30 of the present invention is provided with a relatively large shock-absorbing hole 31 on the outer ring, which reduces vibration and avoids stress concentration on the one hand, and reduces weight and energy consumption of the motor 11 on the other hand. The rotating magnetic disk 30 is also provided with a relatively small ejection hole 32 on the inner ring, which is used to eject the saw blade 1 cm by the internal mechanism after all the teeth of the saw blade are welded, so that the magnetic force is released, and then the material is discharged by the suction cup. Therefore, correspondingly, a mounting plate 80 fixed by bolts is provided on the rear side of the rotating magnetic disk 30, and the mounting plate 80 is provided with an ejection rod 81 driven by a cylinder and passing through the ejection hole 32. The ejection rod 81 shrinks in the ejection hole 32 when welding the saw teeth. The rotating sensor 82 automatically starts the cylinder after the saw blade rotates one circle and all the teeth are welded, drives the ejection rod 81, and ejects the saw blade for a distance. At the same time, the guide sleeve 40 continues to hang to prevent it from falling. Finally, the material is sucked and discharged by the suction cup, which is convenient and practical, avoids the use of a complicated unloading mechanism, greatly reduces the cost, and improves the efficiency.

[0019] It is worth mentioning that the motor 11 controls the intermittent motion of the drive shaft 20 through the groove wheel mechanism 12 to adjust the angular interval of the number of teeth, and is equipped with a reducer to adjust the step ratio, which is convenient and practical.

Changes and variations made by those skilled in the art do not depart from the spirit and scope of the present invention, and should be within the scope of protection of the claims attached to the present invention.
