The hydraulic chuck is a rubber cylinder structure with oil pressure clamping and spring release. It has the characteristics of automatic centering and large clamping force. Its pressure oil enters the chuck body through the oil filter, oil distribution device and spindle oil channel on the box body. The leakage oil of the oil distribution mechanism returns to the oil filter and enters the oil tank after passing through the gearbox. This part of oil not only lubricates the gears and bearings, but also takes away the heat generated by the gear stirring oil. The rotator 83 adopts a slot structure and is mounted on the carriage of the feed member 81. The feed oil cylinder drives the carriage to reciprocate along the fuselage guide rail to realize the feeding or pulling of the drill bit.

The upper end nut is loosened and the upper pull rod is turned over to lower or take out the thick-diameter drill tool. Two groups of adjustment gaskets are provided at the connection between the clamp 85 and the feed piece 81, which are used to adjust the center height of the clamp 85 slip group to make it consistent with the center height of the main shaft of the rotator 83. The angle adjuster 86 is composed of two angle-adjusting multi-stage cylinders, a beam, and a column. When the elevation angle needs to be adjusted, the screws on the diagonal support and the screws on the middle support rod are loosened, and the extension and retraction of the multi-stage angle-adjusting cylinder at the front of the feed piece 81 are controlled by the operating lever 7 on the console to adjust the elevation of the machine.
