Description

Technical Field

[0001] The utility model relates to a cutting auxiliary device, in particular to a shaft cutting positioning device. Background Art

[0002] According to the processing requirements, cylindrical shafts need to be cut into segments to cut longer shafts into segments of required length. Currently, one way to cut such shafts is to measure the length with a ruler and mark it before cutting. This will result in a large error in the length of the cut shaft segment, which will affect the cutting effect of the shaft. Another way to cut is to set an adjustable positioning baffle on the base and place the end of the shaft against the positioning baffle to achieve fixed-length cutting. This method can overcome the problem of different lengths of the cut shaft segments. However, the lengths of the segments of different lengths need to be readjusted, which is cumbersome to operate and is not conducive to improving cutting efficiency.

[0003] Chinese patent CN202020836689.2 discloses a shearing device for processing water heating pipes, including a cutting frame, an adjusting frame, a mounting box and a clamping frame, wherein the top of the mounting box is equipped with a mounting frame through a mounting table, a mounting seat is installed in the clamping frame, a through-going bidirectional screw rod is rotatably installed inside the mounting seat, a clamp is installed on the outside of the bidirectional screw rod through a sleeve, and a turntable is fixedly installed at one end of the bidirectional screw rod. When the shearing device for processing water heating pipes cuts a cylindrical shaft into sections, it cannot perform stable fixed-length cutting of the section length, and it is also necessary to measure with a ruler before cutting.
