[0015] Compared with the prior art, the present invention provides a clamping device for drilling double gears, which has the following advantages:

[0016] 1. This utility model utilizes a stepper motor. A drive gear, which engages with a gear ring, is fixedly mounted on the top of the stepper motor's shaft. The gear ring is fitted into the bottom of the connecting tube. The stepper motor drives the connecting tube to rotate via the drive gear and gear ring. A limiting piston is mounted in an "X" shape at the top of the connecting tube, with its movable end pointing towards the axis of the connecting tube. A guide groove that engages with the limiting teeth is provided at the front end of the base. Rubber anti-slip pads are provided on the upper and lower sides of the limiting teeth. A sliding connection is formed between the limiting teeth and the base. The limiting piston drives the base to move towards the double gear, causing the limiting teeth and the double gear to mesh. After meshing with the double gear, the limiting teeth are unable to slide inside the base due to pressure, thus restricting the position of the double gear. This allows the double gear to rotate during the rotation of the connecting tube, thereby adjusting the drilling position.

The tray is fixedly mounted on the top of a supporting piston, which is symmetrically mounted above the base plate with the center of the base plate as a reference. The supporting piston can adjust the position of the tray to support the double gear. During drilling, the drill bit is positioned above the "V"-shaped notch on the rear side of the tray, preventing damage to the tray when the drill bit penetrates the double gear. Furthermore, the drilling position can be maintained directly above the "V"-shaped notch on the rear side of the tray by adjusting the rotation angle of the double gear. This method avoids damage to the supporting structure when the drill bit penetrates the double gear. Attached Figure Description
