Numerical control large-blade knife power head

Abstract

The invention relates to a numerical control large-blade knife power head. Two differential idler bevel gears (4) are respectively connected above and below an input bevel gear (3), and the two differential idler bevel gears (4) are connected with a servo motor bevel gear (5); a main shaft flange (14) is sleeved on a main shaft (1), and a second bevel gear (12) and a first bevel gear (11) are installed on the spindle flange (14); the first bevel gear (11) is fixedly sleeved on the periphery of a screw rod (6), a sliding block (7) is fixedly installed beside the screw rod (6), the sliding block (7) is pressed by fixed blocks (10) on both ends of the sliding block (7), and the fixed blocks (10) are fixed by screw caps on both ends of the screw rod (6); the part of the sliding block (7) toward the screw rod (6) is provided with a semi-circular cavity (9); a transmission shaft (2) is movably installed inside the main shaft (1); the first bevel gear (11) and the second bevel gear (12) are mutually meshed; the screw rod (6) and the sliding block (7) are fixedly installed on the main shaft flange (14); and a blade knife body (13) is fixedly installed on the sliding block (7). The productprovided by the invention has excellent parallelism on both ends and low labor intensity.

Description

(1) Technical field [0001] The invention relates to a machine tool, in particular to a numerically controlled power head for large-scale cutters in a flange plane numerically controlled machine tool. (2) Background technology [0002] The flange plane processing of the pump industry in our country adopts horizontal (vertical) machine tools to process the flange planes at both ends separately. The workpiece rotates, and the parallelism of the two planes of the processed product flanges is not good. The labor intensity is high, the efficiency is low, and the energy consumption is low. Big. [0003] On the basis of the original patented CNC power head (application number 2009.101004615), we have carried out research and development of a new type of rotating mechanism for spreading knives. (3) Contents of the invention [0004] The technical problem to be solved by the invention is to provide a numerically controlled large-scale cutter power head with high working efficiency,...
