Drilling device used for forged steel pressure release valve connecting flange machining

Abstract

The invention discloses a drilling device used for forged steel pressure release valve connecting flange machining in the technical field of pressure release valve connecting flange machining. The drilling device comprises a base. A sliding block is in inserted connection to the top of a supporting frame in a penetrating manner. A locking device is arranged at the bottom of the left side wall of the sliding block. An air cylinder is arranged in the middle of the bottom side wall of the sliding block. A motor is arranged on the bottom side wall of a connecting plate. A drill rod is arranged onthe bottom side wall of the output end of the motor. A workbench is movably arranged in the middle of the top side wall of the base. Two sets of clamping devices are movably arranged on the top side wall of the workbench. According to the device, a flange is clamped through a supporting plate, the circle center of the flange and the circle center of the workbench are located on the same vertical line, and the flange is prevented from moving accidentally during drilling; the workbench is rotated, the drilling position on the flange can be adjusted, the flange is prevented from moving, and therefore it is guaranteed that the distance between each set of holes and the circle center of the flange is the same; and the accuracy of drilling is improved, and the work efficiency of workers is improved.

Description

technical field [0001] The invention relates to the technical field of processing the connecting flange of a pressure relief valve, in particular to a drilling device for processing the connecting flange of a forged steel pressure relief valve. Background technique [0002] The connection flange of forged steel pressure relief valve needs to be drilled on the flange during processing and production, but the existing flange drilling device has simple functions, and the flange needs to be moved continuously during drilling, and different positions on the flange need to be drilled. Drilling, but this will easily lead to deviations in the drilling position, resulting in the fact that when the two sets of flanges are connected in the later stage, the two sets of holes cannot be completely connected. Therefore, we propose a drilling method for the connection flange processing of forged steel pressure relief valves. device. Contents of the invention [0003] The object of the pr...
