The rotary drive mechanism of numerical control steel reinforcement cage forming machine
Technical field
The utility model relates to numerical control steel reinforcement cage forming machine, particularly be the rotary drive mechanism of numerical control steel reinforcement cage forming machine.
Background technology
At present, numerical control steel reinforcement cage forming machine is the special equipment with automation processing steel reinforcement cage.The process of prior art numerical control steel reinforcement cage forming machine is, earlier with main muscle according to the varying number requirement, penetrate and clamp main muscle termination in the hole of towing plate, drive mechanism drags the cage draw-gear to move towing plate, be fixed on the towing plate and the main muscle that drag on the cage draw-gear moves thereupon, rotating disc rotation, manipulator are twined stirrup and are welded on the main muscle outside, make steel reinforcement cage.
The prior art numerical control steel reinforcement cage forming machine drives the rotating disk rotation and adopts four jiaos slave unit support rotating disc is set, transferring power adopts the structure of the direct driven gear tooth bar engagement of motor, there is following defective in this structure: four point-supported modes are difficult to adapt to the requirement that rotating disc still can smooth operation at a high speed and under the situation of speed change because the error of processing and assembling be difficult to be eliminated.Motor directly drives the transmission mechanism of hard engagement, and when equipment fast turn-around, noise is very big and bigger to the vibratory impulse of motor.And common electric machine can't count or count inaccurate.
Summary of the invention
A purpose of the present utility model is to overcome the deficiency of above-mentioned technology, and a kind of bearings rotating disc of integral body is provided, and rotating disc high speed speed change is steadily rotated, automaticity height, the rotary drive mechanism of the numerical control steel reinforcement cage forming machine that reduces labor intensity.
Another purpose of the present utility model is to adopt the servomotor source that is used as power, and is with the driving-belt movable sprocket synchronously, realizes the smooth operation of high speed speed change, and precisely steel reinforcement cage end product quality and speed of production are improved in the location.
The technical scheme that solves the problems of the technologies described above is: a kind of rotary drive mechanism of numerical control steel reinforcement cage forming machine, described rotary drive mechanism comprises: underframe, be fixed on frame, rotating disc on the underframe, one end of described rotating disc is hinged in the frame endoporus, and rotating disc other end outward flange is chain fixedly; Be fixed on the frame with the chain drive of chain engages.
The beneficial effects of the utility model are: the purpose of this utility model is to overcome the deficiency of above-mentioned technology, provide a kind of can steady, atwirl rotary drive mechanism.The utility model automaticity height has greatly reduced operating personnel, has alleviated labor strength, has improved production efficiency.The utility model also has simple in structure, and is easy to maintenance, and stable working is saved energy consumption, the advantage that processing cost is low.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is implemented to be described in further detail.
Fig. 1 is the utility model front view; Fig. 2 is an A-A cutaway view among Fig. 1; Fig. 3 is the rearview of Fig. 1; Fig. 4 is a B-B cutaway view among Fig. 1.
As shown in the figure, the utility model provides a kind of rotary drive mechanism of numerical control steel reinforcement cage forming machine, and described rotary drive mechanism comprises: underframe 1, be fixed on frame 2, rotating disc 3 on the underframe 1.
One end of described rotating disc 3 is hinged in frame 2 endoporus, and rotating disc 3 other end outward flanges are chain 5 fixedly; Be fixed on the frame 2 with the chain drive of chain 5 engagements.
Described chain drive comprises: sprocket wheel 6, rotating shaft 7, big belt wheel 8, small pulley 10, servomotor 11; Described sprocket wheel 6 is fixed on rotating shaft 7 one ends and meshes with chain 5; Rotating shaft 7 is supported on the frame 2, and rotating shaft 7 other ends connect big belt wheel 8, is with 9 to connect big belt wheel 8 and small pulley 10 synchronously, and small pulley 10 is contained on servomotor 11 output shafts.
The utility model adopts servomotor, by synchronous band driving-belt movable sprocket, can realize the smooth operation of high speed speed change, precisely the location.
Be provided with bearing 4 between one end of described rotating disc 3 and frame 2 endoporus.Be the end that the inner ring of bearing 4 is equipped with rotating disc 3, adopt whole bearings rotating disc, can realize the smooth operation of high speed speed change, improve the end product quality and the speed of production of steel reinforcement cage.
Below the course of work of the present utility model is described:
When the utility model rotary drive mechanism is started working, start-up control system at first, servomotor 11 is started working, servomotor 11 drives small pulley 10 rotations, thereby by being with 9 transmissions to drive big belt wheel 8 rotations synchronously, thereby the drive by rotating shaft 7 makes sprocket wheel 6 rotations, and sprocket wheel 6 drives the rotation of rotating disc 3 with fixedly chain 5 engagements, the rotation of sprocket wheel 6 by chain 5.
