Scraping and deburring are one of the means commonly used, there are a lot of cutter mechanisms of scraping and deburring on the market, along with the demand improvement of automated production, robotic arm is also a commonly used equipment, has developed a burring double knives and has pressed flexible scraping mechanism to solve the relevant problem that the burring appears on the production through the needs in my company's technical staff combines the actual production.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a scrape burr sword dress instrument to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a scrape bush-cutter dress instrument that goes, includes flange, fixing base and handle of a knife seat are installed to the flange front end, the multiple-blade scraper is installed through the handle of a knife fixed block in handle of a knife seat upper end, a rotatory lever is installed to fixing base one side, fixing base upper right end is installed and is compressed tightly cylinder and spring stopper, flexible spring is installed in the cooperation of spring stopper lower extreme.

Further: the multi-edge scraper consists of a cutter handle and a cutter head.

Further: the tool bit is provided with a cutting edge A, a cutting edge B, a cutting edge C and a cutting edge D in sequence.

Further: the shape of the knife handle is a triangular prism structure.

Further: the four cutting edges on the cutter head form a trapezoid shape.

Further: the tool bit is made of hard alloy by grinding, and the hardness is more than 40 HRC.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model can be used for the deburring requirement of the appearance of complex mechanical parts; the chamfering machine is used for chamfering mechanical parts needing to be smooth and less than 0.5 mm; the deburring machine is used for deburring of copper alloy parts, carbon steel alloy, aluminum alloy and other parts with the hardness of below 40 HRC. In the manufacturing process of the scraper, the position degrees of the lower edge of the triangular positioning tail handle and the cutting edge axis of the alloy scraper are strictly controlled within 0.02mm, and the repeated precision of the cutting edge after the cutter is replaced is ensured within 0.05 mm. The included angle of the cutting edge is 40 degrees, so that the cutting edge can be cut into the bottom of the included angle of the part to be scraped better, the cutting edge A is mainly responsible for scraping three angles of the inner edge of the hollowed-out part, and the cutting edge B is mainly responsible for scraping three angles of the inner edge and the outer edge which are approximately horizontal or vertical; the cutting edge C is mainly used for scraping three knife angles of the outer edge angle of the part; blade D is responsible for the scraping of narrow and small space edges and corners, and four blades can cut into angle work more in three sword scraping angle scraping processes, and the following is the advantage to different technologies:

1) in the deburring and scraping of the robot acting platform, along with the complex appearance of a part, in the process requirement of scraping edges and corners by three knives, the strict requirement is provided for the angle of each knife, so that the optimal cutting angle can be found more easily by the layout of the flag-shaped cutting edge which can achieve the effect of the arc edge and the angle which can not be covered by a plurality of common scrapers, and the structure can cover the angles;

2) compared with the appearance of the traditional burr scraper, the structure is arranged on the action platform by a robot, and due to the unique four-edge layout, the programming track is simplified, one third of programming time of a programmer is saved, the action track is shortened, the single-cycle production takt time is saved, and the efficiency is improved;

3) the utility model discloses sword portion adopts carbide to grind, is suitable for at 40 HRC's material to hardness to the life cycle is long, and through verifying copper alloy, aluminum alloy etc. compares traditional high-speed steel scraper longe-lived 10-15 times.
