Abstract

An anti-skidding perforating machine for building circular arc components comprises a first shell. A drill chuck is arranged at the front end of the first shell. A drill bit is arranged in the drill chuck. An installing base is arranged on the drill chuck. An annular positioning device 3 is arranged on the installing base and comprises first touch arms and second touch arms. The first touch arms are hinged to the installing base, the lower ends of the first touch arms can stretch, the second touch arms are hinged to the first touch arms, and suction cups are arranged at the bottoms of the second touch arms. A second shell is arranged at the tail of the first shell. The second shell is in sliding connection in the first shell. A cam is arranged in the second shell. An ejector rod is matched with the cam and fixed to the first shell. The anti-skidding perforating machine for the building circular arc components has the following beneficial effects that no skidding exists when the components with curved faces are perforated, positioning is accurate, and the device is small, simple, easy to implement, convenient to carry and suitable for construction sites.

Description

technical field [0001] The invention belongs to the field of drilling machines, in particular to an anti-slip drilling machine for arc-shaped parts used in construction. Background technique [0002] When machining architectural parts, in order to ensure the processing requirements, first find the corresponding position point on the part and determine its position on this plane, so that the parts to be processed will not be affected by external forces during the processing. The position changes, so it is necessary to use a fixture to tighten the parts to be processed. Some parts need to be drilled on the surface. The traditional drilling method uses a pistol drill to directly punch holes on the parts. This method of drilling is easier on flat parts. However, when punching holes on parts with curved surfaces, due to the curved surface structure, it is difficult for the staff to operate, the work efficiency is low, and the precision of the punched holes is not high, it is easy...
