方矩形管内焊接毛刺在线切除装置
摘要：
本发明公开了一种方矩形管内焊接毛刺在线切除装置，其特征在于它由置于在线方矩形管内的箱体(1)、滚轮(2)、微型电机(3)、切除装置(4)以及拉动管(5)和电源导线(6)构成，箱体(1)底部设有滚轮(2)，微型电机(3)安装在箱体(1)内，微型电机(3)转动轴从箱体(1)的上壁中部伸出并固定上切除装置(4)，拉动管(5)的前端固定在箱体(1)的后壁上，后端沿在线方矩形管的内腔向后伸至在线方矩形管的未闭合缝的宽度大于拉动管(5)的直径位置向上伸出，电源导线(6)穿过拉动管(5)的管腔与微型电机(3)连接。该装置，能够一边焊接，一边随时将焊接毛刺切除，使生产出的方矩形管内侧无焊接毛刺。
摘要（英）：

The invention discloses an online removing device of welding burrs in a square tube. The online removing device is characterized by consisting of a box (1), a roller (2), a micromotor (3), a removing device (4), a pull tube (5) and a power lead (6) which are all arranged in an online square tube; the roller (2) is arranged at the bottom of the box (1); the micromotor (3) is arranged in the box (1); the rotating shaft of the micromotor (3) extends out from the middle part of the upper wall of the box (1) and is fixed on the removing device (4); the front end of the pull tube (5) is fixed on the rear wall of the box (1), and the rear end extends backwards along the cavity of the online square tube to the position where the width of the unclosed seam of the online square tube is larger than the diameter of the pull tube (5); and the power lead (6) passes through the cavity of the pull tube (5) and is connected with the micromotor (3). The device can carry out welding and welding burr removing at the same time so that no burr exists inside the produced square tube.
