Flange hole drilling equipment with high machining precision

Abstract

The invention discloses flange hole drilling equipment with high machining precision. The flange hole drilling equipment comprises a box body, a base plate, a pressing plate, a cutter head, a cutter handle and a cross beam, wherein a mounting frame is fixed to the lower side of the interior of the box body; the base plate is fixedly installed at the top of the mounting frame through bolts; meanwhile, a first through hole is formed in the surface of the base plate; a supporting framework is fixedly welded to the upper side of the mounting frame; a first opening is formed in the center of the supporting framework; a second opening is formed in the center of the base plate; and a boss is fixed to the lower side in the mounting frame. According to the flange hole drilling equipment with the high machining precision, the base plate, the pressing plate and a three-jaw chuck are arranged, a flange is arranged at the outer side of the three-jaw chuck in a sleeving mode, the flange is positioned through the three-jaw chuck, then a second hydraulic cylinder pushes the pressing plate to descend, the pressing plate and the base plate are matched to press the flange, the fixing tightness of the flange is greatly improved, the flange is prevented from vibrating when the flange is machined by a multi-shaft drill bit, the machining precision of the flange is improved, and the use is more practical.

Description

Technical field [0001] The present invention relates to the technical field of flange hole drilling equipment, and is specifically a flange hole drilling apparatus having high machining accuracy. Background technique [0002] The flange is a part connected to each other between the shaft and the shaft, and the two flanges typically use the blend between the bolts and nuts. At this time, the bolt is penetrating through the flange surface, in order to quickly and accurately processed on the flange surface The through hole is therefore necessary to use the flange hole drilling equipment. [0003] The existing flange hole drilling equipment is usually not provided with a chip cleaning device. When mass production flange, the chips on the surface of the workbench is easy to scratch the flange surface, and the existing flange hole drilling equipment is only three claws. The chuck is fixed flange, but the multi-drill bit simultaneously with the flange drilled, the flange is large, and i...

Problems solved by technology

[0004] The purpose of the present invention is to provide a flange hole drilling equipment with high machining accuracy, to solve the problem that the existing flange hole drilling equipment proposed in the above-mentioned background technology is usually not provided with a chip cleaning device. , the chips on the surface of the table are easy to scratch the surface of the flange, and the existing flange hole drilling equipment only uses a three-jaw chuck to fix the flange, but when multiple drills drill the flange at the same time, the pressure on the flange is relatively high. Large, it is easy to cause the flange to vibrate during drilling, which in turn leads to a decrease in the drilling accuracy of the flange, which greatly affects the quality of the finished flange
