Embodiment Construction
[0009] Such as figure 1 , figure 2 As shown, the rotating short arm used for the chamfering machine of the present invention comprises a bottom plate 1, and one end of the bottom plate 1 is provided with a cylindrical protrusion 2 protruding from the plane of the bottom plate 1, and a shaft hole 8 is provided in the cylindrical protrusion 2, so that The shaft hole 8 is perpendicular to the plane of the bottom plate 1 and runs through the bottom plate 1. The inner wall of the shaft hole 8 has a rectangular keyway 9. The shaft hole 8 is used to install the rotating shaft, and the roller is fixedly installed on the rotating shaft; the other end of the bottom plate 1 An inverted L-shaped plate 4 is fixed, which forms a fixed groove body 6 with the other end of the bottom plate 1, and the fixed groove body 6 is used for installing a rotating shaft. Two parallel rib plates 3 are also fixed on the bottom plate 1. The plane of the rib plate 3 is perpendicular to the plane of the bot...

The invention relates to a rotating short arm used for a chamfering machine, which comprises a bottom plate. One end of the bottom plate is provided with a shaft hole which is vertical to a plane of the bottom plate and penetrates the bottom plate, and the inner wall of the shaft hole is provided with a rectangular key groove; and the other end of the bottom plate is fixed with an inverse L-shaped plate which forms a fixed groove body with the other end of the bottom plate. The rotating short arm is characterized in that the bottom plate is also fixed with two parallel rib plates, and planes of the rib plates, the plane of the bottom plate and a vertical plate plane of the inverse L-shaped plate are mutually vertical. After the rotating short arm is arranged on the chamfering machine, because the bottom plate is provided with the rib plates vertical to the plane of the bottom plate and the vertical plate plane of the inverse L-shaped plate, the strength and bending resistance of the whole rotating short arm are greatly improved, so that the rotating short arm is not bent and deformed during long-term use, the quality of a product is ensured, and simultaneously the fault rate is reduced.
Description
technical field [0001] The invention relates to a chamfering device, in particular to a short rotating arm for a chamfering machine. Background technique [0002] The T-shaped bar used in shipbuilding is welded by the panel and the web. In order to meet the needs of the paint and the use environment, the four corners of the panel must be processed into rounded corners of R1.5~3. At present, the arm body of the rotating short arm of the chamfering machine is relatively poor in strength and bending resistance due to structural limitations. In the case of long-term use, it is easy to bend and deform, resulting in low product quality and adverse effects on production. Contents of the invention [0003] The object of the present invention is to design a rotating short arm for chamfering machine, which has a simple and reasonable structure, relatively high bending resistance and strength, can improve product quality, and ensure smooth production. [0004] According to the techn...
