Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in fig. 1-2: the utility model provides a quick burring instrument of aluminum pipe hole, includes handle 1, and handle 1 can be for T style of calligraphy handle, cross handle or small-size motor all can, fixedly connected with supporting body 2 under the handle 1, swing joint has scraper device 3 on the 2 sides of supporting body, scraper device 3 and the contact of aluminum pipe hole 5, handle 1 rotates the drive scraper device 3 is along the rotatory cutting burr of aluminum pipe hole 5. When burr needs to be scraped, only the scraper device 3 needs to be placed in the aluminum pipe inner hole 5 with the corresponding size, the handle 1 is rotated, the scraper device 3 can simply and quickly remove burr on the aluminum pipe inner hole 5, and the burr removing efficiency is high.

The supporting body 2 is provided with a first through hole 21, the scraper device 3 is arranged in the first through hole 21, the scraper device 3 comprises two symmetrical cutter sets 31, a spring 32 is arranged between the cutter sets 31 in the first through hole 21, the distance between the two cutter sets 31 is adjusted by the extension and contraction of the spring 32, and the spring 32 pushes the cutter sets 31 to abut against the inner hole 5 of the aluminum pipe. The spring 32 can adjust the interval between two cutter group 31 to satisfy the aluminum pipe hole 5 burring demand of different pipe diameters, spring 32 makes cutter group 31 can effectual laminating on aluminum pipe hole 5 owing to the bounce that the compression produced, makes the burring in-process, cutter group 31 can not the landing.

The cutter set 31 includes a cutter 311 and a slider 312, the slider 312 is connected to the cutter 311 by a thread, and the slider 312 slides in the first through hole 21 to drive the cutter 311 to move axially along the first through hole 21.
