The invention relates to a hole drilling clamping device. The hole drilling clamping device comprises a supporting table, a clamping mechanism, a hole drilling mechanism and a conveying mechanism, wherein the supporting table comprises a table top and supporting columns, and a first supporting seat and a second supporting seat are disposed on the table top; the clamping mechanism comprises an aircylinder and an abutting block, the air cylinder is hinged to the first supporting seat, a hinge shaft is hinged to the second supporting seat and connected with a piston rod, the abutting block is slideably connected to the table top, and a pull rod is hinged between the abutting block and the hinge shaft; the hole drilling mechanism comprises hole drilling support, a hole drilling table and a rotating disc, a driving gear is mounted inside the hole drilling table and comprises an active gear body and a passive gear body which are engaged with each other, the active gear body is a sector gearand is connected with a motor, a shaft hole is formed in the center of the passive gear body, the rotating disc is mounted at the upper end of the hole drilling table and comprises a disc body, a rotating shaft, clamping grooves and a chassis, and the rotating shaft is disposed in the shaft hole of the passive gear body in a penetrating mode; and the conveying mechanism is a conveying belt. By means of the hole drilling clamping device, the problems that the hole drilling efficiency is low, and the potential safety hazards exist when workpieces are taken away manually after hole drilling in the hole drilling process are solved.
