Abstract
The utility model introduces a blade fastening device used for a blade rotary disintegrator. The blade of the blade fastening device is arranged in a cutter groove of a rotary cutter body, a wedge block sliding groove is arranged under the blade, a wedge-shaped block which can slide is arranged in the groove, and a fastening screw is arranged on the wedge-shaped block. When the screw is screwed tightly, the wedge-shaped block is pulled to slide outward; thereby, the blade in the cutter groove is fastened. The utility model can disintegrate high-strength materials, and can not produce a cutter-flying phenomenon caused by blade damage; thus, the strength of the cutter body is increased, and the use safety performance of the disintegrator is improved.
Description
The utility model belongs to the jig field of cutter, relates in particular to the gripping mechanism of rotary cutter.
In rotary blade pulverizer, all be fastened with several blades equably on the cutter hub of rotation, blade fastening method commonly used is to be evenly distributed with several cutter grooves on the circumference of rotation cutter hub, all be provided with a blade in each cutter groove, have through hole on blade, blade is fastened in the cutter groove with high-strength screw.Adopt the fastening blade of said method, run into intensity higher by comminuting matter the time, take place easily that blade fractures or screw is broken and the dangerous phenomenon of fly cutter occurs.
The purpose of this utility model is: a kind of gripping mechanism that is not easy to take place the rotary cutter of fly cutter phenomenon is provided.
For achieving the above object, the technical solution of the utility model is to be evenly distributed with several cutter grooves on the circumference of pulverizer rotation cutter hub, all is fastened with a blade in each cutter groove; Blade of inlaying in the cutter groove and cutter groove are to be slidingly matched, below the cutter groove, be provided with the wedge slides groove that communicates with the cutter groove, be provided with a wedge type piece in the wedge slides groove, the last plane of wedge type piece contacts with the bottom surface of blade, the lower inclined plane of wedge type piece contacts with the inclined-plane of wedge slides groove, at the wedge type piece vertical with the bottom surface of blade and with plane that wedge type piece microcephaly links to each other on, vertically be provided with a tapped through hole that has counterbore, be provided with a screw in this hole, the microcephaly of screw withstands on the back plane of wedge slides groove.
Advantage of the present utility model is: adopt the blade of said structure, owing to do not have through hole on the blade, make the intensity of blade improve; In addition, because the contact-making surface of blade and cutter hub increases, make the adhesion of blade and cutter hub increase synchronously, thereby significantly reduced the generation of " fly cutter " phenomenon.
Below in conjunction with accompanying drawing the utility model is done explanation in further detail:
Fig. 1 is on the utility model rotation cutter hub, a structure installation diagram in many blade gripping mechanisms.
In Fig. 1, be evenly distributed with several cutter grooves 2 on the circumference of pulverizer rotation cutter hub 1, all be fastened with a blade 3 in each cutter groove 2, cutter groove 2 is to be slidingly matched with blade 3, below cutter groove 2, be provided with the wedge slides groove 7 that communicates with cutter groove 2, be provided with a wedge type piece 9 in the wedge slides groove 7, the last plane of wedge type piece 9 contacts with the bottom surface of blade, the lower inclined plane of wedge type piece 9 contacts with the inclined-plane 8 of wedge slides groove, at wedge type piece 9 vertical with the bottom surface of blade and with plane 6 that wedge type piece microcephaly links to each other on, vertically be provided with a tapped through hole 5 that has counterbore, be provided with a screw 4 in this hole, the microcephaly of screw 4 withstands on the back plane 10 of wedge slides groove.
When screwing screw 4, screw 4 holds out against the bottom surface 10 of wedge slides groove 6, makes wedge type piece 87 outwards slide along the inclined-plane, and then with blade 3 chuckings.
