Embodiment Construction

[0010] Further describe technical scheme of the present invention below in conjunction with accompanying drawing: pulley transmission type oblique vertical trephine, it comprises base plate 1, base 2, swivel seat 3, bit case 4, belt pulley 5, motor 6, spacer 7, wherein Motor 6 is installed among the bit box 4, and belt pulley 5 is placed on the bit box 4, is suspended state. When drilling, put the base 2 that matches the shaft hole of the outer water distribution ring into the shaft hole of the outer water distribution ring, and fix the base 2, the bottom plate 1 and the outer ring with the bolt top copper gasket 7, and turn the rotating base 3 to realize the position indexing of the hole, and adjust the diameter position of the hole by moving the drill box 4. The drill bit should be controlled within a certain length range due to the limitation of its stroke. The drill bit speed is the slow speed in the reasonable speed determined through extensive investigation. If the speed...

Abstract

The present invention discloses belt pulley driven inclined vertical trephine and its usage. The belt pulley driven inclined vertical trephine includes back plate, pedestal, rotating base, bit case, belt pulley, motor and washer. During drilling hole, the pedestal matching the shaft hole of the outer water distributing ring is installed inside the shaft hole of the outer water distributing ring, the outer water distributing ring is screwed to the pedestal and the base plate, the rotating base is rotated for indexing, and the bit case is shifted to regulate the diameter position of the hole, so as to machine screw hole and positioning hole in the shaft hole end of the outer water distributing ring. The present invention has compact structure and simple process, and can facilitate the machine of screw hole and positioning hole in the shaft hole end of the outer water distributing ring.

Description

technical field [0001] The invention relates to an oblique vertical trephine and its usage method, in particular to a pulley driven oblique vertical trephine and its usage method. Background technique [0002] The inner and outer water distribution rings of bulb type units are large workpieces in hydroelectric power generation equipment. Because the guide vane shaft holes of the inner and outer water distribution rings form a certain angle with the installation or processing base surface, the screw holes and positioning holes distributed on the end surface of the shaft hole of the outer water distribution ring have a certain degree of processing under the condition of no large-scale special equipment. Difficulties. In the past, the screw holes and positioning holes on the end surface of the shaft hole on the outer water distribution ring were processed by using a universal drill to process the pilot holes. Then lift one end of the workpiece with the hoisting crane, so that...
