Description
Technical field
The utility model relates to one and is applied to Pneumatic friction piece break on large pressing machine, relates in particular to the brake pad structure of this brake pad break.
Background technique
Brake pad break is used widely on large pressing machine, in order to realize the fast braking of press machine transmission part.
The brake pad break of prior art, its fixed body is arranged on press frame, and rotor is arranged on the transmission shaft of press machine, adopts individual layer brake pad structural type.Due to the needs of its braking moment, its boundary dimension is huge, and not only Master Cost is high, and manufacturing cost is high, and the maintenance cost of the quick-wear parts such as brake pad is also high, does not meet very much the requirement of low-carbon economy.
Summary of the invention
The utility model technical issues that need to address have been to provide double-deck brake pad break for a kind of large pressing machine, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: fixed body; Described fixed body is connected with the fuselage of press machine; Described fixed body comprises: break retainer ring, floating disc; Described floating disc is connected with break retainer ring by spline, and floating disc can move axially at break retainer ring; Also comprise: rotor; Described rotor is connected with press machine transmission system; Described rotor comprises: brake seat, the first brake pad retainer, first group of brake pad, spacer, the second brake pad retainer, second group of brake pad; First group of screw is connected to the first brake pad retainer, spacer and the second brake pad retainer on brake seat; First group of brake pad is set in the first brake pad retainer hole, can move to axial; Second group of brake pad is set in the second brake pad retainer, can move to axial; Also comprise: carry out assembly; Described execution assembly comprises: cylinder body, piston, the first seal ring, the second seal ring, thrust disc, force transmiting disk, brake spring, stud bolt and locking nut; Piston is arranged in cylinder body, is sealed by the first seal ring and the second seal ring, and thrust disc and force transmiting disk connect by stud bolt and locking nut; Brake spring compresses thrust disc and forces in second group of brake pad surface, and second group of brake pad moves axially promotion floating disc, and floating disc moves axially and forces in first group of brake pad again, realizes and engaging; Carrying out assembly is connected with fixed body by second group of screw.
Compared with prior art, the beneficial effects of the utility model are: brake pad break adopts double-deck brake pad structural type, and while realizing the moment of torsion same with individual layer brake pad structural type, break external diameter can reduce half, is only that thickness size increases to some extent; Thereby significantly reduce break Master Cost, save manufacturing cost, reduce the maintenance cost of friction material.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
The utility model comprises: fixed body; Described fixed body is connected with the fuselage of press machine; Described fixed body comprises: break retainer ring 1, floating disc 2; Described floating disc 2 is connected with break retainer ring 1 by spline, and floating disc 2 can move axially at break retainer ring 1; Also comprise: rotor; Described rotor is connected with press machine transmission system; Described rotor comprises: brake seat 3, the first brake pad retainer 4, first group of brake pad 6, spacer 5, the second brake pad retainer 8, second group of brake pad 9; First group of screw 7 is connected to the first brake pad retainer 4, spacer 5 and the second brake pad retainer 8 on brake seat 3; First group of brake pad 6 is set in the first brake pad retainer 4 holes, can move to axial; Second group of brake pad 9 is set in the second brake pad retainer 8, can move to axial; Also comprise: carry out assembly; Described execution assembly comprises: cylinder body 10, piston 15, the first seal ring 14, the second seal ring 16, thrust disc 18, force transmiting disk 17, brake spring 13, stud bolt 12 and locking nut 11; Piston 15 is arranged in cylinder body 10, is sealed by the first seal ring 14 and the second seal ring 16, and thrust disc 18 and force transmiting disk 17 connect by stud bolt 12 and locking nut 11; Brake spring 13 compresses thrust disc 18 and forces in second group of brake pad 9 surface, and second group of brake pad 9 moves axially and promote floating disc 2, and floating disc 2 moves axially and forces in first group of brake pad 6 again, realizes and engaging; Carrying out assembly is connected with fixed body by second group of screw 19.
Compared with prior art, the change of its maximum is to be to become two groups of brake pads from one group of brake pad to the utility model, carries out assembly consistent with prior art.
Working principle of the present utility model is: in the time that the transmission shaft of press machine turns round, enter cylinder body 10 from outside pressurized air by gas port A, promoting piston 15 moves, piston 15 promotes force transmiting disk 17 and pulls thrust disc 18 to overcome brake spring 13 by stud bolt 12 to be moved to the left, and second group of brake pad 9 and first group of brake pad 6 all discharge.In the time that needs are braked press machine transmission system, cylinder body 10 compressed airs are discharged from gas port A, and brake spring 13 promotes thrust disc 18 and moves right, and promote 9, the second groups of brake pads 9 of second group of brake pad and promote floating disc 2, first group of brake pad 6 again; Thrust disc is pressed on two groups of brake pads, floating discs on retainer ring 1 like this, the friction that relies on the dual face of the dual face of second group of brake pad and thrust disc and floating disc, first group of brake pad and floating disc and retainer ring to produce, realizes press machine transmission system and brakes rapidly.
