Summary of the invention
The purpose of the utility model be a kind of effective assurance rotor basic circle of designing for the deficiency that solves above-mentioned technology machining accuracy and the comparatively easy rotor basic circle cavetto device for scraping of operation.
The rotor basic circle cavetto device for scraping that the utility model designed comprises the support of tool rest, scraper, rotary head, rotary knife base and a bending, and scraper is connected on the rotary head; Rotary head is connected on the rotary knife base, and rotary knife base is connected on the support, and bracket end is arranged in the tool rest; Have a pin-and-hole and kidney slot on the said tool rest; Pin-and-hole is positioned at the kidney slot below, is provided with the lock-screw of lock bracket in the kidney slot, is provided with the fastening bolt as the support pivot point in the pin-and-hole; On tool rest, the both sides of support are furnished with two adjustment bolts that are oppositely arranged, adjustment bolt end and support offset.
As preferably:
Said support is that sharp corner is the rectangular-shaped of arc transition;
Said adjustment bolt end is a ball head structure; And Quenching Treatment can be adopted, the effect of lock bracket after guaranteeing to adjust in the bulb surface;
Scraper is the switchblade that is made up of cutter hub and cutter head, the U type shape of gap in the middle of cutter hub and cutter head are; Like this, cutter head becomes elastic construction with cutter hub, and when running into excessive resistance, elastic construction can play the effect of buffering, avoids the excessive incision of knife to cause surface of the work to damage.
Said kidney slot is that angle is 56 ° a deep-slotted chip breaker;
Said fastening bolt is interior hexagonal articulation bolt;
The rotor basic circle cavetto device for scraping that the utility model designed can not be accomplished under the existing required precision situation in common turning processing, utilizes this device, adopts the top to decide the mode machining benchmark circle of diameter cutting, the circularity of ability better controlled basic circle.Because of the adjustability of the support of this device, can combine thick, accurate adjustment is whole, satisfies the processing request of the basic circle of different size, contains existing rotor journal specification basically, has enlarged the scope of application of scraping, economic benefit is fine.
