Burr removal device

Abstract

The invention provides a burr removal device. The burr removal device comprises a fixed base, radial driving mechanisms and a scraper blade unit. A positioning base is rotationally connected to the fixed base. A positioning chamber is formed in the upper side of an inner chamber of the positioning base. A positioning tool is arranged on the positioning base. A gear ring is fixed to the interior ofthe positioning chamber by the positioning tool. Receding openings are formed in the two sides of a column surface of the fixed base. Each of the two radial driving mechanisms comprises a sliding rail and a supporting block. The two sliding rails penetrate through the fixed base through the receding openings, and are respectively driven to slide along the two receding openings. The lower ends ofthe two supporting blocks are fixedly connected to the tail ends of the two sliding rails respectively, and extend into the positioning chamber from the interior of the fixed base. The scraper blade unit comprises two scraper blades including the upper scraper blade and the lower scraper blade. The two scraper blades are installed at the top ends of the two supporting blocks respectively. A tool bit is formed on the side, close to the positioning base, of each of the two scraper blades. The tool bit of the upper scraper blade is used for making contact with the upper side face of a snap springgroove. The tool bit of the lower scraper blade is used for making contact with the lower side face of the snap spring groove. According to the burr removal device, burrs on the wall surface of the snap spring groove in the inner wall can be conveniently removed.

Description

technical field [0001] The invention belongs to the field of deburring, and in particular relates to a deburring device. Background technique [0002] Deburring is a very important process in the process of workpiece processing. It not only affects the subsequent processing, but also affects the quality of the workpiece, assembly accuracy, and even the life and noise of the box. [0003] In sample development and small batch processing, manual filing is generally used to remove burrs, or manual electric (pneumatic) tools are used to remove them. In addition, there are many deburring methods at present, such as thermal deburring, electrochemical deburring, freezing deburring, engraving machine deburring, electrolytic deburring, high pressure water deburring, ultrasonic deburring. [0004] However, for workpieces with complex shapes, hard and large burrs, using traditional methods is either too costly or unsatisfactory to remove them. At present, there is still a lack of mat...

Problems solved by technology

[0004] However, for workpieces with complex shapes, hard and large burrs, using traditional methods is either too expensive or the removal effect is not ideal. At present, there is still a lack of mature processing methods and techniques to solve this problem.

[0005] This device is aimed at a planetary ring gear with a terminal tooth structure in a planetary gearbox, such as figure 1 As shown, the burrs on the wall of the circlip groove are difficult to remove
