Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific examples, which are not intended to limit the scope of the invention.
As shown in fig. 1-2, the automatic chamfering machine tool for drum brakes of the present embodiment includes a frame 1, a material guide chute 2 is disposed at the top of the frame 1, and the frame 1 is sequentially provided with a feeding mechanism 3, a feeding mechanism 4, a chamfering mechanism 5, a dust removing mechanism 6, and a material collecting chute 7;
the feeding mechanism 3 comprises a material box 31 arranged at the starting end of the material guide chute 2, a push plate 32 and an air cylinder 33, the material box 31 is in a shape like a Chinese character 'ji', a stop block is arranged on the inner side of an open end of the material box 31, the material box 31 stretches across side plates on two sides of the material guide chute 2, a cylinder body of the air cylinder 33 is fixed on the rack 1, the push plate 32 is fixed at the end part of a piston rod of the air cylinder 33, and the push plate 32 is arranged in the material guide chute 2 and slides along the material guide chute 2;
the feeding mechanism 4 comprises a feeding wheel 41 which is arranged on the frame 1 and driven by a motor, the feeding wheel 41 is a friction wheel, and the feeding wheel 41 props against the inner arc of the brake pad;
the chamfering mechanism 5 comprises a slide rail 51 fixed on the frame 1 and a slide plate 52 connected with the slide rail 51 in a sliding manner, a screw 53 for driving the slide plate 52 to move is arranged between the slide rail 51 and the slide plate 52, one end of the slide plate 52 is hinged with a motor base 54, angle adjusters 55 are arranged on two sides of the other end of the slide plate 52, the other end of the motor base 54 slides in the angle adjusters 55 through pins and is fastened by nuts, a chamfering motor 56 is fixed on the motor base 54, and a grinding wheel 57 is fixed at the output end of the chamfering motor 56;
the dust removing mechanism 6 comprises a steel brush wheel 61 which is arranged on the frame 1 and driven by a motor, and the steel brush wheel 61 is a roller wheel with a large number of fine steel wires densely distributed on the surface.
The embodiment realizes the procedures of automatic feeding, chamfering and deburring of the drum brake pad, dust cleaning, grinding of the inner arc surface, automatic vertical stacking of the brake pad, is full-automatic, greatly improves the efficiency, reduces the production cost and reduces the labor intensity of workers.
In production, a worker only needs to put a stacked brake block into the material box 31 from the upper part of the material box 31, the air cylinder 33 reciprocates, the brake block at the bottommost layer is pushed out of the material box 31 through the push plate 32 and is pushed to the lower part of the feeding wheel 41, and then the feeding wheel 41 rotating at a constant speed pushes the brake block to move forwards along the material guide groove 2 through friction force; the brake pads of the embodiment move in the material guide groove 2 by means of the power provided by the material feeding wheel 41, and the brake pads move forward in the material guide groove 2 at a constant speed in an end-to-end manner because the material feeding wheel 41 rotates at a constant speed. When the brake pad moves to the chamfering mechanism 5, the rotating grinding wheel 57 chamfers and polishes burrs on the upper and lower edges of the two sides of the brake pad, the steel brush wheel 61 can clean dust on the surface of the brake pad, particularly on the inner arc surface of the brake pad, and the finally processed brake pad enters the material collecting groove 7 to be collected.
Since the magazine 31 is disposed across the side plates on both sides of the chute 2, the depth of the chute 2 is the distance from the bottom of the chute 2 to the bottom of the magazine 31; the depth of the material guide groove 2 is greater than the thickness of one brake pad and less than the thickness of two brake pads, and when the inner arc surface of the brake pad adopted in the embodiment is placed upwards, the overall height is about 30mm, so that the depth of the material guide groove 2 is greater than 30mm and less than 60mm, and 40mm is adopted in the embodiment; thus, the push plate 32 can only push out one brake pad at a time, and when the brake pad advances in the material guide groove 2, the inner arc of the brake pad faces upwards.
