[0006] The technical solution is: a flange processing adaptive positioning and opening device, including a base, a tailstock, a motor, a drill bit, an elastic pressure rod, a three-jaw chuck and a clamping mechanism. The upper rear side of the base is slidably connected to the tailstock, the upper front side of the tailstock is connected to the motor, the drill bit is slidably connected to the motor output shaft, the middle part of the tailstock is slidably connected to the elastic pressure rod, the elastic pressure rod is connected to the drill bit, and the upper middle part of the base is connected to the three-jaw chuck. The flange is limited by the three-jaw chuck, the elastic pressure rod is pressed downward to drive the drill bit to move downward and contact the flange, the motor output shaft rotates to drive the drill bit to rotate to open a hole in the flange, and a clamping mechanism for clamping the flange is provided on the base.

[0007] Further description, the clamping mechanism includes a main wheel plate, a secondary wheel plate, a telescopic rod, a top frame, a strong spring, a clamping wheel, an inner spring, a double spring and a sliding block.

The telescopic rods are all slidably connected with sliding blocks, which are connected to the tailstock. Double equal springs are connected between the left and right parts of the main wheel plate and the auxiliary wheel plate and the sliding blocks. After the flange is placed on the three-jaw chuck, the distance between the main wheel plate and the auxiliary wheel plate is adjusted according to the size of the flange under the action of a strong spring, so that the clamping wheel contacts the flange, and then the sliding block is driven to always be located at the center of the telescopic rod under the action of the double equal spring. The sliding of the sliding block drives the tailstock to slide back and forth, thereby driving the drill bit to adjust its position.

[0008] It is further explained that a guide rod is provided on the base to facilitate guiding the main wheel plate and the secondary wheel plate.

[0009] Further description, it also includes a fixing mechanism, which includes a fixing frame, side springs and a clamping plate. The left and right sides of the front and rear parts of the base are connected with fixing frames, and clamping plates are slidably connected between two adjacent fixing frames. Multiple side springs are connected between the clamping plates and the adjacent fixing frames. The clamping plates are first pulled to the side away from each other to separate them from the main wheel plate and the secondary wheel plate. The side springs are stretched under force, and the side springs rebound to drive the clamping plates to slide and reset to the side close to each other, and the main wheel plate and the secondary wheel plate are locked by the clamping plates.

[0010] Further explanation: each of the pallets is provided with a handle to facilitate pulling the pallet.

[0011] Further description: card slots are provided on the card boards.

[0012] Beneficial effect: The utility model automatically adjusts the distance between the main wheel plate and the secondary wheel plate through the action of a strong spring, so that the clamping wheel contacts the flange, and drives the drill bit to move through the sliding block under the action of the double equal spring, which can achieve the effect of quickly and automatically adjusting the drill bit position according to the size of the flange, which is more convenient.
