When the hole drilling machine is drilling, the hole drilling bit will be subjected to the reaction force of the pipe wall. This reaction force includes the reaction force along the axial direction of the hole drilling bit and the reaction force along the rotation direction of the hole drilling bit. The axial reaction force is transmitted After the upper seat is applied, a radial bending moment will be applied to the lifting column. Over time, the structure of the lifting column will be deformed, causing the drilling machine to lose its lifting function; and the reaction force in the direction of rotation will make the drilling bit feed unstable. In addition to the processing error of the lifting column and the installation of the upper seat on the existing drilling machine, the drilling bit is prone to jumping, resulting in damage to the drilling bit or its driving structure

The invention discloses a tapping machine upper seat lifting device. The tapping machine upper seat lifting device comprises two lifting stand columns fixedly arranged on a machine seat of a tapping machine, and the two lifting stand columns are provided with an upper seat in a sliding mode. The upper seat is provided with upper seat slideways corresponding to the lifting stand columns. The two lifting stand columns are arranged in a central symmetry mode relative to a rotary shaft of a tapping drill bit. The lifting stand columns are provided with lifting racks. The upper seat is provided with a lifting driving shaft. The lifting driving shaft is provided with a lifting gear corresponding to one of the lifting racks. The lifting driving shaft is connected with a lifting driving device. The upper seat is connected with an upper seat returning device. According to the tapping machine upper seat lifting device, the two lifting stand columns are arranged in the central symmetry mode relative to the tapping drill bit, so that influences of bending moment on the lifting stand columns can be effectively reduced. Meanwhile, the lifting stand columns and the upper seat slideways matched through shaft holes are small in error and more stable in movement, and jumping of the tapping drill bit can be effectively reduced.
Description
technical field [0001] The invention relates to the technical field of drilling machines, in particular to a lifting device for an upper seat of a drilling machine. Background technique [0002] The drilling machine is a device used to open holes in the pipe wall to facilitate the side connection of the pipeline. The structure of the existing drilling machine is usually fixedly installed lifting column on the machine base, the upper seat is slidably installed on the lifting column, the hole drilling bit and its driving structure are installed on the upper seat, and the feeding action of drilling is realized by the lowering of the upper seat. When the hole drilling machine is drilling, the hole drilling bit will be subjected to the reaction force of the pipe wall. This reaction force includes the reaction force along the axial direction of the hole drilling bit and the reaction force along the rotation direction of the hole drilling bit. The axial reaction force is transmitte...
