The working principle and the process of the invention are as follows:
as shown in fig. 1, firstly, a support frame of the discrete speed-dividing box is used, the support frame is mainly supported by a base 1 arranged on the support frame, a motor support 40 is fixed on the base, and then a first-stage cam support plate is carried, wherein the first-stage cam support frame 3, the first-stage speed-dividing support plate 4, the first-stage speed-dividing support frame 5, the reducer support plate 6, the reducer support frame 7, the reducer press plate 8, the second-stage cam support frame 9, the second-stage cam support plate 10, the second-stage speed-changing support frame 11, the second-stage speed-changing press plate 12, the output-end support frame 13, and the output-end press plate 14 are fixedly.
As shown in figure 2, the power output by the motor is transmitted to the power dividing mechanism, the power dividing mechanism is composed of three cams, a cam lower cushion block and a cam upper cushion block, the power output by the cams can be distributed in proportion by changing the profiles of the cams, if the three cams are uniformly distributed at 120 degrees, the three push rods simultaneously reach the farthest positions when the cams move to the maximum stroke, but the time of the process is changed according to the different profiles of the cams, so that the purpose of power dividing is achieved.
When the power output by the motor is transmitted to the cam group, the spring acts to make the roller closely contact with the cam profile when the push rod is at the base circle of the cam, the spring is compressed when the cam rotates to the lift, and the elastic force of the spring is released during the return stroke to change the rotation of the motor 41 into reciprocating motion through the cam group. Then the power is transmitted to the first speed reversing mechanism, as shown in fig. 5, three first speed reversing mechanisms are uniformly arranged in 120 degrees, a first speed reverser supporting block 30A of the three first speed reversing mechanisms is fixedly connected with a push rod, the push rod transmits the power in reciprocating motion to the first speed reversing mechanism, and the first speed reversing supporting block 30A of the first speed reversing mechanism reciprocates in a first speed reversing chute 31A. As shown in fig. 6, the first-speed-commutator upper rack 29A and the first-speed-commutator lower rack 29B are fixed in the first-speed-commutator chute 31A and reciprocate together with the chute. As shown in fig. 7, the first speed reverser upper rack 29A and the first speed reverser lower rack 29B rotate the first speed reverser upper gear 45A and the first speed reverser lower gear 45B, wherein the first speed reverser upper ratchet wheel 44A and the first speed reverser lower ratchet wheel 44B are fixed to the shaft, the first speed reverser upper gear 45A and the first speed reverser lower gear 45B rotate relative to the shaft, the first speed reverser upper pawl 47A is hinged to a spoke of the first speed reverser upper gear 45A, and the first speed reverser lower pawl 47B is hinged to a spoke of the first speed reverser lower gear 45B. When the input is in forward translation, the rotation directions of the first speed reverser upper gear 45A and the first speed reverser lower gear 45B are opposite, and at the moment, the first speed reverser lower pawl 47B is meshed with the first speed reverser lower ratchet wheel 44B, so that the shaft rotates clockwise; when the backward translation is input, at the moment, the pawl 47A on the first speed reverser is meshed with the ratchet wheel 44A on the first speed reverser, the shaft is also rotated clockwise, and if the rotating direction of the shaft is changed, the two ratchet wheels only need to be simultaneously exchanged in the assembling process, and the anticlockwise output rotation can be realized.
As shown in fig. 2, the first-stage speed reversing mechanism changes the translation of the power splitting mechanism into rotation, and then inputs power into the speed reducer through the coupling group, the power is transmitted to the cam of the second-stage speed reversing mechanism through the speed reducer group, the cam rotates to drive the three rollers arranged above, the rollers drive the double-light-rod support fixedly connected with the rollers, and the rollers are matched with the springs on the light rods to make the double-light-rod support reciprocate on the light rods arranged up and down to drive the three long connecting rods to rotate, so that the power is output through the three output shafts, and the effect of single-power multi-branch output is realized.
