Speed-adjustable turning equipment for flange surfaces with same bore

Abstract

The invention discloses speed-adjustable turning equipment for flange surfaces with the same bore. The turning equipment comprises a rotary bottom plate, an engine base and a transmission feeding mechanism. The transmission feeding mechanism is structurally characterized by comprising a counterweight component, a chain transmission mechanism, a gear transmission mechanism, a screw rod transmission mechanism and a turning cutter, wherein the rotary bottom plate is fixed on a boring rod; the engine base is fixed on the rotary bottom plate; the chain transmission mechanism, the gear transmission mechanism and the screw rod transmission mechanism are arranged on the engine base; the counterweight component is connected with the chain transmission mechanism; the chain transmission mechanism drives the gear transmission mechanism; the gear transmission mechanism drives the screw rod transmission mechanism; and the turning cutter is arranged on the screw rod transmission mechanism. Under the action of the counterweight component, a chain wheel of the chain transmission mechanism is rotated, so that a cutter is driven to feed. The turning equipment has reasonable structural design, can feed and retract the cutter automatically and stably in the turning process of a boring machine, and can adjust the cutter feeding speed.

Description

technical field [0001] The invention relates to a turning device for a boring machine, in particular to a turning device with adjustable speed and simultaneous boring of the flange surface, which is mainly used for processing the inner and outer guide rings of the mixed-flow hydroelectric generating set and the same boring flange surface. Background technique [0002] With the development of my country's hydropower technology, the capacity of hydroelectric generator sets is increasing, and the parts are getting larger and larger, which makes the processing and manufacturing equipment larger and larger, and the precision requirements are getting higher and higher. The water guide mechanism is the core component of the water turbine, and its processing quality directly affects the performance and efficiency of the entire unit. In the simultaneous boring process of the inner and outer guide rings of the water guide mechanism, the scraping process of the inner and outer flange f...

AI Technical Summary

Problems solved by technology

In the simultaneous boring process of the inner and outer guide rings of the water guide mechanism, the scraping process of the inner and outer flange faces must be high-precision and high-quality. The existing domestic technology is to add a turning head to the boring bar for scraping, which makes the processing time Long, low efficiency, affecting the quality and accuracy of the flange surface

[0003] The application number is 200810049865.1, and the Chinese patent application document titled "Self-feed Differential Planetary Swivel" discloses a self-feed differential planetary swivel, including a slant disk, fixed wheel gears, planetary gears, active Gears, driven gears, worms, worm gears, driving slides, worm bars, worms, etc., the disadvantage is that the transmission distance of planetary gears is small, and it is inconvenient for the equipment to change the radial feed speed through gears

[0004] The application number is 201020259579.0, and the Chinese utility model patent titled "A Multifunctional Tool Holder for a Boring Machine" discloses a multifunctional tool holder device including a tool holder spindle, two sets of NW planetary gear trains, a manual-automatic conversion device and a fixed It is composed of shaft and wheel system, which can solve the problem of automatic feed and speed regulation of the tool under the operation of the main shaft. The disadvantage is that there are many equipment parts and complex mechanical structure.
