[0050] It should be noted that the present invention is a wafer cutting machine bed precision welding positioning device, when in use, it is installed in a suitable place, and then according to the size of the three-hole component, the positioning device can be divided into two use forms;

[0051] Form 1: When the size of the three-hole component is too large, the multi-stage electric telescopic rod 32 is started, so that one end of the rod is lifted up with the fixing plate 33 to a suitable position and stops, and then the motor 4 35 is started, so that the motor 4 35 acts on the fixing frame 2 34 to rotate the storage ring 6 to a suitable angle and then stops. At this time, the storage ring 6 is erected and reaches a vertical state with the support plate 36;

[0052] Then start the motor 1 4 to rotate the bidirectional screw rod 3, so that the two slide plates 5 move to the appropriate position and stop, then place the three-hole component at the appropriate position between the two storage rings 6, start the motor 1 4 to move the two slide plates 5 to the appropriate position and stop, at this time, the three-hole component is held by the two gear rotating disks 7;

[0053] If the length of the three-hole component is greater than the width, or the width is greater than the length, the threaded rod 30 is rotated according to the actual situation so that the corresponding baffle 13 moves to a suitable position and then stops, and then the motor 29 is started to make the gear plate 20 mesh with the gear ring 21, so that the limit plate 17 rotates and moves the slider 12 toward the center of the gear rotating plate 7 to a suitable position and then stops. At this time, the pressure plate 26 fits the outside of the three-hole component to clamp it;

[0054] During the process, if the outside of the three-hole component is a regular shape, the bolt fastener 28 is inserted into the corresponding reserved hole of the connecting block 27 and fixed so that the corresponding plurality of pressing plates 26 form a unified working plane and perform the clamping work synchronously. If the outside of the three-hole component is irregular, the bolt fastener 28 can be removed;

[0055] Usage state two: If the three-hole component is small in size, start the motor four 35 to make the fixing frame two 34 rotate with the storage ring 6 to a suitable position and stop. At this time, the storage ring 6 is laid flat and parallel to the support plate 36, and then start the multi-stage electric telescopic rod 32 to move it down with the storage ring 6 to a suitable position and then stop. During the process, the storage ring 6 moves down with the docking tube 38 synchronously, so that the docking tube 38 gradually moves down toward the corresponding support rod 37, and finally the support rod 37 is inserted into the corresponding docking tube 38, which supports the storage ring 6. Then the three-hole component is placed on the corresponding gear rotating disk 7, and it can be clamped in the same way as in the usage state one.
