Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings 1-3.
As shown in fig. 1-3, a wear-resistant sealing structure for a cutting tool comprises a cutting tool 1, an output shaft 2, a housing 3, a first contact surface 4, a second contact surface 5, a third contact surface 6, a silica gel sealing ring 7 and an elastic sealing device 8; the cutter head of the cutter 1 is inserted into the inner cavity of the output shaft 2; a shell 3 is further sleeved outside the cavity port of the output shaft 2, and a first contact surface 4 and a second contact surface 5 are sequentially arranged between the shell 3 and the output shaft 2 along the outward direction of the cavity port of the output shaft 2; a third contact surface 6 is also present between the housing 3 and the tool 1; the first contact surface 4, the second contact surface 5 and the third contact surface 6 are arranged in a ladder shape; the shell 3 of the first contact surface 4 is in threaded connection with the output shaft 2; a silica gel sealing ring 7 is arranged between the shell 3 of the second contact surface 5 and the output shaft 2 at the outer end of the port of the inner cavity of the output shaft 2 in the outward direction, the silica gel sealing ring 7 is bonded on the shell 3, and the silica gel sealing ring 7 is gradually reduced in the outward direction of the port of the inner cavity of the output shaft 2; an elastic sealing device 8 is arranged between the shell 3 in the middle of the third contact surface 6 and the cutter 1, and the elastic sealing device 8 comprises a silica gel sealing ring main body 81, a spring element 82 and an arc-shaped panel 83; a spring element 82 is arranged in the middle of the silica gel sealing ring main body 81, arc-shaped panels 83 are welded at two ends of the spring element 82, and the outer side surfaces of the arc-shaped panels 83 are arc-shaped surfaces; the spring element 82 is clamped in the silica gel sealing ring main body 81 through an arc-shaped panel 83 at the end part; the two sides of the silica gel sealing ring main body 81 are also provided with protruding structures which are clamped and fixed with the preformed groove of the shell 3.
