Adjusting and detecting device for cutting edge gap of rotary cutter and detecting method thereof

Abstract

The invention discloses an adjusting and detecting device for the cutting edge gap of a rotary cutter and a detecting method thereof. The adjusting and detecting device comprises an upper case, a displacement sensor, a lower case, a spring and a follow-up lever, wherein the upper case is installed on the cutting body of the rotary cutter by bolts; the lower case is screwed on the upper case by bolts and forms a complete closed case with the upper case; the follow-up lever tightly presses the outside where an upper cutter shaft is assembled through the spring; the displacement sensor is provided with a movable magnet and is screwed in the central position of the closed case formed by the upper case and the lower case through screw threads; and the movable magnet is screwed on the follow-uplever by bolts. The invention uses the mode that the follow-up lever is assembled and followed up with the upper cutter shaft, causing the movable magnet in the displacement sensor which is screwed onthe follow-up lever to move correspondingly, the moving distance can be read directly through a display meter or an interface card of the displacement sensor, or a controller can be used for operation, and automatic detection and control are realized.

Description

Technical field [0001] The invention relates to a disc shear, in particular to a disc shear blade gap adjustment detection device and a detection method thereof. Background technique [0002] Disc shears play a very important role in the medium and heavy plate steel rolling production line. It is used to cut the two sides of the rolled steel plate to make the steel plate shape and size meet the requirements of the national standard. Whether the adjustment amount of the disc shear blade gap is appropriate or not directly affects the shear quality of the steel plate, which requires a disc shear blade gap adjustment detection device. figure 1 Shown is a schematic diagram of an existing disc shear blade gap adjustment and detection device. Disc shear blade gap adjustment detection is to directly use the encoder 11 at the tail of the transmission reduction motor 12 of the worm gear 14 adjustment mechanism to detect the adjustment gap size of. Due to the influence of the gear backlash...
