Description
Technical field
The present invention relates to a kind of mechanical tank twister for twisting iron core of motor.
Technical background
Usually the iron core of motor reverses to stepping, servomotor and machinery and reverses.Stepping, servomotor reverse can realize all kinds of needs that reverse, but its stability is poor slightly, and cost is high.It then is good stability that machinery reverses, and cost is low.Traditional machinery is turned round the groove device and is quickened for the single gear transmission, when customer demand product windup-degree is big, needs to adopt the multistart worm turbine, and its manufacture difficulty is high, and cost is high and unstable.If adopt single start worm then can only strengthen the gearratio of external gear, promptly need a gear and the gear matched that diameter is very little that diameter is very big, cause the volume of turning round the groove device big, and the shortcoming that gear wheel is prone to and mould interferes.。
Summary of the invention
Turn round the shortcoming that volume is big, easy and mould interferes of groove device for overcoming existing machinery, it is little to the invention provides a kind of volume, do not interfere with mould, but the torsional amplitude of product is big mechanical tank twister for twisting iron core of motor with low cost.
Mechanical tank twister for twisting iron core of motor; Moving up and down of upper bolster converts the torsional device that the drive product rotates into when comprising mould die sinking, matched moulds; Described torsional device comprises the litter affixed with the upper bolster of mould; Described litter is provided with can be along its linkage that horizontally slips; Described linkage comprise connecting-rods with constant lengh that is connected with litter and the adjusting rod that is connected with said connecting-rods with constant lengh through fastening bolt, described adjusting rod be provided with allow fastening bolt slide up and down, with the regulating tank of the entire length that changes linkage, the described adjusting rod and first fork are hinged; Drive power shaft when affixed, the described fork of the power shaft of described first fork and a gear box moves up and down and rotate, the output shaft of described gear box is connected with the worm screw of driven product rotation;
It is characterized in that: described power shaft is provided with first driving gear, and the jack shaft of gear box is provided with first driven gear with the described first driving gear engaged transmission; Described output shaft is provided with second driven gear, and described jack shaft is provided with second driving gear with the second driven gear engaged transmission.
Further, described first driving gear is connected with described power shaft through first unilateral bearing, and described second driving gear is connected with described jack shaft through second unilateral bearing, and described output shaft is connected with gear case body through the 3rd unilateral bearing.
Further, described first fork below is provided with the position-limit mechanism of restriction fork hunting range, and described position-limit mechanism comprises rod swinging frame and is arranged at rod swinging frame upper end, telescopic set screw.
Further; Described adjusting rod bottom is provided with first set bolt and second set bolt that clamps described first fork, be fixed in the top of second set bolt with the described second set bolt nut engaged so as bolt to move up and down, away from or push against described fork.
Further, described turning round also is provided with second torsional device in the groove device, and second fork and the described jack shaft of described second torsional device are affixed.
Technical conceive of the present invention is: when upper bolster moved up and down because of the opening and closing mould, litter and linkage were followed upper bolster and are moved up and down, and rotated thereby drive fork.The power shaft of fork and gear box is affixed, and rotatablely moving after the acceleration through gear box, with this is passed to the worm screw of driven product rotation, thereby realizes reversing of product.
The present invention makes the diameter of the diameter of driving gear greater than driven gear through the two-stage gear drive, realizes that two-stage drives up, and increased gearratio effectively, but the torsional amplitude of product is big.
Driving gear is connected with axle through unilateral bearing; When first fork drove the power shaft rotation, first driving gear was followed power shaft and is rotated, and rotated thereby drive first driven gear; The jack shaft and second driving gear are followed first driven gear and are rotated, and output shaft is followed second driven gear and rotated.
When second fork drove the jack shaft rotation, through the engaged transmission of second driving gear and second driven gear, output shaft rotated.When promptly using second fork, have only one group of gear to drive up, gearratio is less, can be used for the product that only need reverse by a small margin.
When needs adjustment fork length, only need linkage is slided along litter, fork slides between first, second set bolt, promptly is adjustable to the required length of fork.
It is little that the present invention has a volume, do not interfere with mould, but the torsional amplitude of product is big advantage with low cost.
