Machining device for space deep inclined holes in large wind power box

Abstract

The invention discloses a machining device for space deep inclined holes in a large wind power box, wherein the machining device is low in input-output ratio. A connecting positioning plate is connected with the large wind power box, and the inclined face at one corner of the connecting positioning plate corresponds to the inner circular-arc face of the periphery of the mounting face on the largewind power box. The face, facing the large wind power box, of the connecting positioning plate is the positioning face. A guiding positioning plate comprises a transition part and a guiding part whichis flush with the upper surface of the transition part to form the guiding positioning face provided with a magnetic electric drill. Corresponding corners corresponding to the inclined corners of thefirst space deep inclined hole and the second space deep inclined hole in the large wind power box are formed between the guiding positioning face and the positioning face on the connecting positioning plate. A first guiding hole and a second guiding hole which correspond to the first space deep inclined hole and the second space deep inclined hole correspondingly are formed in the guiding part.Two linings are assembled in the first guiding hole and the second guiding hole in an interference mode correspondingly, and a deep hole quick-changing drill bushing and a screw hole quick-changing drill bushing are in clearance fit with the two linings correspondingly. The hole diameters of the deep hole quick-changing drill bushing and the screw hole quick-changing drill bushing are slightly larger than the outer diameter of a drill bit of the magnetic electric drill.

Description

technical field [0001] The invention belongs to a processing device for a large-scale wind power box, in particular to a processing device for deep oblique holes in the upper space of a large-scale wind power box. Background technique [0002] see figure 1 and figure 2 As shown, a common large-scale wind power cabinet 100 weighs several tons, and is provided with two parallel to each other and forms an oblique angle D with respect to the front surface of the large wind power cabinet 100, both of which have threaded holes at the open ends. Space deep inclined hole I101 and space deep inclined hole II102. At present, since the large-scale wind power box weighs several tons, it is impossible to rotate the bevel D according to the conventional method and then install it on the corner seat of the traditional machining equipment to process the space deep inclined hole I101 and the space deep inclined hole II102 by rotating the workbench. . Usually, the processing of the space...

Problems solved by technology

At present, since the large-scale wind power box weighs several tons, it is impossible to rotate the bevel D according to the conventional method and then install it on the corner seat of the traditional machining equipment to process the space deep inclined hole I101 and the space deep inclined hole II102 by rotating the workbench.

Usually, the processing of the space deep inclined hole I101 and the space deep inclined hole II102 can only be completed on a large-scale pentahedron machining center. The existing technical problem is; Hole I101 and space deep oblique hole II102 are processed, and a large pentahedron machining center is specially equipped for processing the space deep oblique hole I101 and space deep oblique hole II102 on small batches or several large wind power cabinets 100, then Due to the high price of large-scale pentahedral machining centers, the input-output ratio is high and the economy is poor

At the same time, due to the complex structure of the large-scale pentahedron machining center, not only the operation is more complicated, but also the requirements for operators are higher, and the maintenance cost is also higher
